In the technique scheme, described clamping device one end is hydraulic cylinder, piston bush is contained in the hydraulic cylinder, piston rod end is connected and fixed the first blade, the piston rod periphery is set with back-moving spring, the clamping device other end is toxoplasm, and toxoplasm is connected and fixed by screw thread and hydraulic cylinder, and the toxoplasm installed inside is fixed with the second blade.
In the technique scheme, described clamping device is the hydraulic bench vice structure.
In the technique scheme, described hydraulic shock spanner is existing mature technology, and market is purchased.
Substantive distinguishing features and remarkable result that the utility model is outstanding:
1, when Bolt dismantling, clamped the screw rod of split bolt with the insert cartridges of hydraulic clamp, when effectively preventing Bolt dismantling threaded spindle cap nut the two rotate together.Hydraulic clamp chuck and dismounting are connected as a single entity with the hydraulic shock spanner, and be easy to use by the oil cylinder folding, and the hydraulic pressure great efforts, effective.
2, it is fast to adopt rotary dismounting to compare other hydraulic torque wrench speed
3, suspended structure is adopted in whole provision for disengagement, has effectively alleviated workman's working strength
4, spanner can be realized the dismounting effect that needs high pulling torque just can reach with impulsive force under less moment of torsion in unloading process.
5, applied widely, can be widely used in the dismounting of railway freight-car and the various high strength corrosion of other heavy industry industry bolt, the hook bolt of tearing open that bogie position linking springs supporting plate is connected with bogie side frame when keeping in repair especially for railway freight-car is dismantled, and can be used for other high strength corrosion bolt of dismounting by changing swivel head.
6, the utility model has comprehensively solved the technical barrier that prior art dismounting corrosion bolt exists, and is skillfully constructed, and rational in infrastructure, practicality is good.

The accompanying drawing marking explanation:
The 1-cantilever crane, the 2-travelling car, the 3-balancer, the 4-side is hung, the 5-fairlead, the 6-guide post, 7-provision for disengagement, 8-bearing pin, 9-swing arm, 10-oil cylinder, 11-the first pin, 12-the second pin, 13-connecting screw rod, 14-back tightening nut, 15-clamping device, 16-bolt to be torn open, 17-steel plate, 18-workpiece, 19-connecting plate, 20-hydraulic shock spanner, 21-skeleton, 22-hydraulic cylinder, 23-piston, the 24-toxoplasm, 25-the first blade, 26-the second blade, 27-back-moving spring.
The specific embodiment
Referring to Fig. 1, the utility model comprises: cantilever crane 1, travelling car 2, balancer 3, side extension 4, fairlead 5, guide post 6, provision for disengagement 7.
Provision for disengagement 7 is suspended on the cantilever crane 1, can realize moving forward and backward by travelling car 2, can realize moving up and down by balancer 3, and balancer is actual to be exactly the adjusting device of pulley and rope.Side is hung the both sides that are positioned at balancer, and side is hung and is steel pole, and upper end and travelling car are fixed, and lower end and fairlead are fixed, and guide post passes fairlead and is connected with provision for disengagement 7.Can realize left rotation and right rotation by cantilever crane, like this can the handled easily personnel, reduce labor intensity.
Referring to Fig. 2, described provision for disengagement part is skeleton 21, bearing pin 8, swing arm 9, oil cylinder 10, connecting screw rod 13, back tightening nut 14, hydraulic shock spanner 20, clamping device 15, connecting plate 19, the first pin the 11, second pin 12.
Operation principle:
At first provision for disengagement 7 is positioned over the position that needs dismounting, oil cylinder 10 back cavity oil-feeds, swing arm is opened, swing arm is put in the bolt head top, then the oil cylinder ante-chamber is logical oily, and swing arm is closed, the clamping device clamps bolt head in the swing arm, at the same time, sleeve on the hydraulic shock spanner just in time overlaps top nut, and this two action is finished together, and this has just entered the SBR of Bolt dismantling, then drive the oil cylinder on the clamping device, the clamping screw head prevents its rotation in the time of dismounting, restarts the hydraulic shock spanner, the rotation of hydraulic shock spanner driven rotary cover realizes Bolt dismantling.Opening and closing oil cylinder in the time of dismounting does not have pressure, and the relative motion that screw rod and nut separate is opened swing automatically, and after Bolt dismantling was complete, provision for disengagement entered the SBR of next Bolt dismantling.
Referring to Fig. 3, described clamp mechanism comprises hydraulic cylinder, piston 23, toxoplasm 24, the first blade 25, the second blade 26, back-moving spring 27.Piston 23 is sleeved in the hydraulic jack 22, and piston rod end is connected and fixed the first blade 25, and the piston rod periphery is set with back-moving spring 27, and toxoplasm 24 is connected and fixed by screw thread and hydraulic cylinder, and the toxoplasm installed inside is fixed with the second blade 26.
Operation principle:
After between two blades that enter clamp mechanism wait the screw head of tearing bolt open, start the hydraulic pressure button, the back cavity oil-feed of hydraulic cylinder, the pushing piston bar advances, and piston rod and the first blade link together, and has so just realized that two blades clamp screw head, the blade strip tooth, dismantle complete after, the back cavity off-load relies on compressed back-moving spring that piston top is gone back to the home position.This clamp mechanism has adopted the bench vice structural principle, hydraulic clamp, and clamping force is large, and is locking, easy to operate.
