And described jig is upper and lower symmetrical opening structure, and jig one middle side part is provided with hinge, is provided with the snap close for holding clamp locking state in the middle part of jig opposite side.
And described rubber pad adopts solid rubber to make, and is interior circular rubber pad or interior hexagon rubber pad.
Advantage of the present invention and good effect are:
1, this device is arranged on the top of hydraulic tongs, because hydraulic tongs is lower climbing structure, during crimping top caliper maintain static and bottom caliper upwards lifting crimp, lift-on/lift-off type structure is conducive to the stroke controlling crimping, and balance shaft is convenient to left and right movement, convenient construction, the stressed sync equalizing of both sides, regulates accuracy rate high.
2, this device can control deformation quantity automatically, and control accuracy is high, effectively prevents distortion, be 100% through stand the test rate, and simple to operate, lower for workmen's skill requirement, time saving and energy saving, and construction quality is unified, effective lifting construction qualification rate.
3, the present invention adopts balancing device to replace manual operation first in this area, and after effectively avoiding hydraulic pipe to press, the appearance of distortion and buckling phenomenon, reduces rework rate, improves the quality of hydraulic pipe hydraulic construction; Save construction cost, ensure construction speed and construction quality, adopt this Technical investment cost lower, but carrying out long-distance transmission line construction, especially in large-scale power engineering, the benefit of generation is considerable.
