Definitions
- the present invention concerns vehicles for transporting and/or dispensing coiled pipes.
- the present invention relates to vehicles of the type which are used to transport large coiled pipes of the type used to convey gas or liquids underground.
- the vehicles may be powered vehicles (such as customised trucks) or trailers for towing by another vehicle.
- such vehicles in the prior art take the form of a trailer and are able to hold and transport one or more coils of pipe material which has been formed into a coil for ease of transport.
- the pipe is installed directly into a trench which has been pre-dug to receive the pipe.
- the pipe is forcibly pushed into a pre- installed conduit.
- such a conduit is an existing pipe and the new pipe is used to line the existing pipe.
- Such an installation is relatively common where the integrity or structure of the existing pipe is questionable or coming to the end of its life.
- By forcibly pushing the new pipe into the existing pipe a more economic means of installing pipe is provided. This can be achieved with or without the carrier pipe (pre-existing conduit) being drained/emptied/decommissioned. Such an operation is known respectively as live or dead insertion.
- the coiled pipe may be formed from any suitable material, but is commonly formed from polyethylene (PE). Typical dimensions of the pipes commonly transported by prior art vehicles range in diameter from 50mm and up to 125mm and lengths of up to 500m. Other materials and dimensions of pipe are, of course, possible Figure 1 shows an example of a prior art trailer 500 used to transport coiled pipes to an installation site.
- PE polyethylene
- Prior art vehicles typically take the form of an enclosed cage structure 510 in which the coiled pipe 520 resides.
- the trailer is provided with one or more axles each having a pair of wheels 530.
- a coupling hitch for attachment to a towing vehicle (not shown).
- the trailer 500 shown in figure 1 includes a rotatable hub 550 about which the pipe may be coiled. In the particular example shown, however, a relatively large diameter of pipe is coiled and this resides within the cage 510 of the trailer but is not wound tightly on the hub 550.
- Figure 1 shows a prior art trailer for carrying coiled pipe
- Figure 2 shows the upper part of a vehicle according to an embodiment of the present invention
- FIG. 3 shows a chute, which forms part of the vehicle shown in figure 2;
- Figure 4 shows a retractable conveyor for use in a second embodiment of the present invention
- FIG. 5 shows an embodiment of the present invention with the chute and retractable conveyor in place
- Figure 6 shows the embodiment of figure 5 with a coiled pipe in position
- Figure 7 shows a view of the second embodiment of the invention in use.
- Figure 8 shows a more detailed view of the pipe pusher.
- Figure 2 shows the upper part of a vehicle according to an embodiment of the present invention.
- the upper part of the vehicle is arranged to be fitted to a suitable powered vehicle or to a chassis having wheels and a towing hitch for attachment to a towing vehicle.
- These parts of the vehicle or trailer have been omitted for clarity purposes since these are standard parts and well-known to the skilled person.
- vehicle The structure of embodiments of the present invention will be referred to as a vehicle, and it will be understood that the vehicle will include the structure shown in the figures and described herein, as well as the requisite parts of a powered vehicle or trailer, as appropriate.
- the vehicle 1 comprises a structure, which is generally closed at the sides and generally open at the top, in which is accommodated the coiled pipe to be transported.
- an outer frame 10 which substantially surrounds the coiled pipe whilst it is being transported.
- the outer frame is further provided with a wire mesh which impedes access to the interior of the outer frame and is intended to prevent an operative or other person from placing their arms inside the outer frame since this can be dangerous.
- the wire mesh is not shown in the figures for clarity purposes but the skilled person would appreciate that this can be readily applied to the outer frame by means of welding or other fixing techniques.
- Figure 6 shows a further embodiment of the vehicle, together with a coiled pipe 520in position for transportation and later installation.
- the coiled pipe sits on support rollers 20 .
- At least one of these support rollers 20 is adjustable to accommodate coiled pipes 520 having a different coil diameter.
- the adjustment is performed by means of a suitable provider of motive force, such as a pneumatic or hydraulic system or an electrical motor.
- the adjustment is controlled by an operative by means of a control panel situated outside of the outer frame.
- side rams 25 which may be operated to control the position of the coiled pipe from side to side within the outer frame. This can ensure that the coiled pipe is evenly positioned, does not lean over to one side and is properly located for the free end to be dispensed from the vehicle in a process which will be described shortly.
- lateral bars 35 are used to couple the two longer sides of the outer frame together. These are locked in position and ensure that the coil is retained securely in the vehicle, as shown in Figure 6, where the lateral bars 35 sit within the coil.
- the free end of the coiled pipe is intended to be discharged from the vehicle in the vicinity of one end of the vehicle 30. This may be the front or the rear of the vehicle as required and may depend on whether the particular embodiment is in the form of a trailer or a powered vehicle.
- a chute 40 is provided such that the free end of the pipe passes into the chute and is smoothly guided towards the front 30 of the vehicle, from where it is dispensed.
- the chute 40 takes the form of a smoothly curved channel having a curved concave profile into which the free end of the pipe travels easily and without impairment.
- the chute is shown in Figure 3 and in-situ in Figure 5.
- an operative was required to access the straps through the side of the cage supporting the coiled pipe. This could lead to injury in cases where the cold pipe sprang free with considerable force. Since the operative was accessing the pipe through the side of the cage, this had the potential to cause quite significant injury to the operative.
- an access platform 50 which includes a ladder (not shown) for accessing the upper portion of the coiled pipe.
- the access platform 50 further comprises one or more safety rails 55.
- safety rails 55 surround the access platform and ensure that if an operative, working at the top of the ladder, leans back or otherwise stumbles, he will not fall to the road surface below. In cases where the free end of the pipe is liable to spring out, the operative is quite likely to react in a way which may cause him to fall backwards and be injured.
- the access platform and safety rails is intended to mitigate any risk of that happening, combined with further safety features also herein described.
- the operative is able to access the various straps which secure the coil in formation. From here, the individual straps may be severed or released individually slowly freeing the coiled pipe.
- the coiled pipe is initially located in the vehicle such that the free end of the pipe, which is accessible, is positioned towards the end of the vehicle adjacent the access platform 50.
- the operative fits a towing head into the free end of the pipe and secures its in position.
- the towing head is well-known in the art and includes a device which fits securely inside the open end of the pipe and can be fastened in position such that it cannot be easily released.
- the towing head features an eye at its free end and this eye can be coupled to a towing line (not shown) which is attached to a winch 100 such that the coiled pipe can be uncoiled in a controlled and reliable fashion by use of the winch.
- the winch 100 is located conveniently at the same end 30 of the vehicle from which the pipe is to be dispensed, and is controlled from there or elsewhere by an operative.
- the winch may be powered or manually operable.
- the towing cable runs from the winch 100 to the rear of the vehicle from where it can be attached to the towing head when the coiled pipe needs to be uncoiled.
- the towing cable will be positioned, using a series of rollers and/or pulleys, before the coiled pipe is placed into the vehicle. Once the towing head has been installed into the coiled pipe, the winch cable may be detached from a stowed position and attached to the eye of the towing head.
- the towing head is drawn by means of the towing cable towards the end 30 of the vehicle.
- the winch may be stopped and the strap nearest to the operative may be severed or released accordingly.
- the tension which would otherwise cause the pipe to spring outward and potentially injure an operative is kept under control by means of the winch 100 which is operably connected to the towing head in the free end of the pipe.
- the free end of the pipe is caused to enter the chute 40 and, due to the gently curving nature of the chute, the free end of the pipe travels easily through it and along the lower part of the vehicle where it is guided by one or more rollers.
- the free end of the pipe reaches the end 30 of the vehicle, all of the restraining straps holding the coil in formation will have been removed.
- the free end of the pipe is then dispensed from the vehicle and may be used as required. Such use may involve completely uncoiling the pipe and laying in a trench. Alternatively the pipe may be fed into a device for forcibly pushing it into a pre-existing conduit.
- a pipe pushing machine 200 which is provided on a platform 210 which extends downwardly from the end of the vehicle towards the ground such that the free end of the pipe can be forcibly pushed into the pre-existing conduit, which is already positioned underground.
- Figure 7 shows a view of this second embodiment
- Figure 8 shows a more detailed view of the pipe pushing machine.
- Figure 4 shows a view of the platform 210 which, in transit, is raised so that it does not foul the road. However, when the vehicle 1 arrives at the installation site, the platform is lowered into position. The platform rotates about hinge points 215 so that the other end of the platform 210 sits on or near the ground.
- the winch 100 is located part way up the end of the vehicle such that the towing cable passes through the body of the pipe pushing machine 200, via a roller 220.
- the winch may be detached from the towing head and the towing head may be removed from the free end of the pipe.
- the pipe pushing machine 200 operates in a grasping and reciprocating fashion to slowly push the pipe into a pre-existing conduit underground.
- the pipe pushing machine 200 comprises a collar, having 2 halves 201 , 202, which surround the pipe. Shims of appropriate dimensions may be inserted as needed.
- the two halves can be separated and brought into contact.
- the two halves have a hinged connection 203 on one side and, at the other side, may be opened or closed by means of hydraulic, pneumatic or electrical means 205.
- the 2 halves of the machine are bought into close proximity so that the pipe is gripped firmly.
- the pipe pushing machine is then propelled forward along the platform 210 such that the pipe is forcibly propelled from the vehicle and into an underground conduit.
- the pipe pushing machine 200 Once the pipe pushing machine 200 has reached the end of the platform 210, the pipe pushing machine releases its grip on the pipe by opening the two halves 201 , 202 of the collar. The pipe pushing machine then travels back towards the opposite end of the platform 210, where it again grips the pipe and the process is repeated to push a further length of pipe underground. As will be appreciated, the length of pipe which can be pushed underground in any one action is equal to the length of travel along the platform 210.
- the pipe pushing machine 200 is propelled along the platform by means of hydraulic, pneumatic or electrical force.
- the speed with which pipe may be installed in an underground conduit can be greatly increased. Furthermore, the ease with which the pipe may be initially uncoiled and fed into the pipe pushing machinery as a single process by means of the winch 100, greatly increases the efficiency of the pipe laying operation and significantly reduces the likelihood of any operative being injured during the process.
- a door 60 is provided in one or more sides of the outer frame.
- An operative may be required to enter the interior of the cage to realign the cold pipe or to remove a blockage or obstruction should that be necessary.
- the door 60 is opened and audible and/or visual alarm is provided to other operatives in the vicinity so that they are aware that someone is potentially at danger inside the cage of the vehicle.
- Embodiments of the present invention provide a quicker and safer means of transporting and, particularly, dispensing coiled pipe.
