Fig. 1 is the structural representation of single oil cylinder partial circulating swan neck system.
Among Fig. 1: 1, bend pipe oil cylinder, 10, piston rod, 100, single oil cylinder partial circulating swan neck system, 2, the bend pipe main shaft, 3, regulating wheel, 4, the bend pipe arm, 5, chain, 50, the first cutter chain bar, 51, the second cutter chain bar, 6, chain joint, 60, first chain joint, 61, second chain joint, the 62, the 3rd chain joint, 7, chain stretching device, 70, hinged seat, 71, screw mandrel, 72, regulating wheel bearing, 720, fixed axis, 8, the hole.
The specific embodiment
See also Fig. 1, a kind of single oil cylinder partial circulating swan neck system 100, this list oil cylinder partial circulating swan neck system 100 comprises: bend pipe oil cylinder 1, bend pipe main shaft 2, regulating wheel 3, be installed on the bend pipe arm 4 on the bend pipe main shaft 2, number cutter chain bar 5, several chain joints 6 and chain stretching device 7, described bend pipe oil cylinder 1 is provided with piston rod 10, described chain 5 comprises and is sheathed on the first cutter chain bar 50 on the bend pipe main shaft 2 and is sheathed on the second cutter chain bar 51 on the regulating wheel 3, described chain joint 6 comprises first chain joint 60, second chain joint 61 and the 3rd chain joint 62, the described first cutter chain bar 50 is by first chain joint 60 and piston rod 10 fixing mutually, the described second cutter chain bar 51 is by second chain joint 61 and piston rod 10 fixing mutually, be connected by the 3rd chain joint 62 between the described first cutter chain bar 50 and the second cutter chain bar 51, described the 3rd chain joint 62 is by fixture and bend pipe main shaft 2 fixing mutually, in the present embodiment, described fixture is a pin.Described chain stretching device 7 comprises hinged seat 70, be articulated in screw mandrel 71 on the hinged seat 70, be sheathed on the screw mandrel 71 and the regulating wheel bearing 72 that is threaded with screw mandrel 71, described regulating wheel 3 is supported on the regulating wheel bearing 72, and the central authorities of described regulating wheel bearing 72 are provided with fixed axis 720.
The operation principle of this list oil cylinder partial circulating swan neck system 100 is: hydraulic oil 8 enters from the hole, promoting piston rod 10 moves right, piston rod 10 ends drive bend pipe main shaft 2 by chain 5 and turn clockwise, and bend pipe main shaft 2 drives bend pipe arm 4 again and turns clockwise, and realize the bend pipe action.
In the prior art, the chain tension function normally realize by moving back by curved oil cylinder, it is given by hydraulic system and moves back curved opposite thrust of oil cylinder, realize the tensioning of chain, the active force that the feasible active force of really bestowing on the curved part of the two oil cylinder bend pipe structures of this kind is two oil cylinders generations is poor, and the bend pipe moment of torsion is directly proportional with active force on bestowing curved part, and therefore the bend pipe torque of this kind pair oil cylinder bend pipe structures is less, the bend pipe ability a little less than.
The computing formula of the bend pipe moment of torsion of two oil cylinder bend pipe structures is:
M=(F-F1)?·D/2
F: the thrust (N) that the bend pipe oil cylinder produces
F1: move back the thrust (N) that curved oil cylinder produces
M: bend pipe moment of torsion: Nm
D: bend pipe main shaft diameter (m)
And in the present invention, the chain tension function is realized by chain stretching device 7, has cancelled and has moved back curved oil cylinder, make that the active force of bestowing on the curved part is the thrust that bend pipe oil cylinder 1 produces, thereby increased the bend pipe moment of torsion, improved the bend pipe ability, enlarge the bend pipe specification, saved cost.
The computing formula of the bend pipe moment of torsion of single oil cylinder partial circulating swan neck system is:
M=F·D/2
F: the thrust (N) that the bend pipe oil cylinder produces
D: bend pipe main shaft diameter (m)
M: bend pipe moment of torsion (Nm)
