Detailed description of the invention
Embodiment
Fig. 1 is the structural representation of Simple large-diameter steel pipe bender embodiment of the present invention, as shown in Figure 1, including: for providing the traction apparatus 2 of bending force, swan neck system main body 3 and for connecting the holding clamp 4 of steel pipe 1 to be curved and traction apparatus 2 to steel pipe 1 to be curved, one end of holding clamp 4 is taper round steel, in bend pipe process, it is internal that it inserts steel pipe 1 to be curved, fix with steel pipe 1 to be curved and be connected, Fig. 4 is the structural representation of holding clamp 4 in Simple large-diameter steel pipe bender embodiment of the present invention, and the angle of taper round steel is between 30 degree to 50 degree.The other end of holding clamp 4 is connected with traction apparatus 2 by pull rope 5.Fig. 2 is the plan structure schematic diagram of Simple large-diameter steel pipe bender embodiment of the present invention, Fig. 3 is the side-looking structural representation of Simple large-diameter steel pipe bender embodiment of the present invention, as shown in Figures 2 and 3, swan neck system main body 3 includes by the fixing side supports plate 31 connected of bearing connecting rod 39, two fixing running rollers 32 and an adjustable rolling 33, fixing running roller 32 and adjustable rolling 33 are connected with support plate 31 by rotating axle 34, fixing running roller 32 and adjustable rolling 33 are connected by bearing with rotating axle 34, along with moving of steel pipe 1 to be curved, the moving axis that rotates rotates under the effect of pull rope 5 so to make fixing running roller 32 and adjustable rolling 33.Swan neck system main body 3 is provided with sliding rail 35, and adjustable rolling 33 is fixed on sliding rail 35 by adjusting screw 36 and feed screw nut 37, can pass through leading screw 36 and adjust the centre-to-centre spacing of adjustable rolling 33 and fixing running roller 32.In bend pipe process, regulated the relative position of adjustable rolling 33 and two fixing running rollers by adjustment adjusting screw 36 and feed screw nut 37, thus forming the pressure to steel pipe 1 to be curved.Fixing running roller 32 and adjustable rolling 33 are provided with groove 38, and groove 38 is the arc-shaped groove adapted with steel pipe to be curved so that the outer surface of steel pipe 1 to be curved is fitted with groove 38 all the time in moving process.So owing to, in the moving process of steel pipe 1 to be curved, there is fixing running roller 32 and adjustable rolling 33 pressure to steel pipe 1 to be curved all the time, so that steel pipe to be curved 1 forms certain radian after bend pipe process terminates, meeting the needs of site operation.And, owing to steel pipe 1 to be curved is in moving process, fixing running roller 32 rotates all the time with adjustable rolling 33 together with steel pipe 1 to be curved, therefore avoids and forms cut in steel tube surface to be curved, improve the aesthetics of tube bending rear surface to be curved, and it also avoid the appearance of dog leg phenomenon.
In the present embodiment, the core wheel of adjustable rolling 33 is positioned on the perpendicular bisector of two fixing running roller core wheel lines, the diameter of adjustable rolling and fixing running roller selects same case, the core wheel spacing of two fixing running rollers is not less than 2 times of fixing roller diameter, above-mentioned measure, prove through experiment, being effectively increased the work efficiency of bend pipe operation, most of steel pipes can reach construction requirement through one to twice bend pipe operation.
In the present embodiment, holding clamp 4 is provided with open-work 41, pull rope 5 one end is fixed in open-work 41, the other end is fixed in traction apparatus 2, in the bend pipe process of the present embodiment, the traction angle of pull rope 5 and described steel pipe to be curved is between 5 degree and 30 degree, the control of above-mentioned angle finds in practice of construction process, it is possible to effectively avoid the appearance of bend pipe dog leg phenomenon.
In the present embodiment, steel wire rope selected by pull rope 5, and hoist engine is selected in traction apparatus.
Therefore, the present invention adopts the Simple large-diameter steel pipe bender of said structure, has reached the purpose that large diameter steel pipe is curved, low price, easy construction, the needs that large diameter steel pipe is curved can be met completely, reduce construction cost, facilitate workman's construction.
It is last it is noted that above example is only limited in order to technical scheme to be described, although the present invention being described in detail with reference to preferred embodiment, it will be understood by those within the art that: technical scheme still can be modified or equivalent replace by it, and these amendments or be equal to replacement amended technical scheme also can not be made to depart from the spirit and scope of technical solution of the present invention.
