Cylinders of hydraulic props are fitted with pivots mounted for interaction with bushings of locators arranged in holes of base. Each bushing has cut-out which width exceeds diameter of pivot and forms unclosed surface in the form of arch which embraces pivot of hydraulic prop. Base is equipped with loop, locator is fitted with eccentric carrying groove and with stopper and the latter can be installed in loop of base and groove of eccentric. EFFECT: increased reliability of fixing of hydraulic props in base, improved conditions for assembly- disassembly of hydraulic props. 3 dwg |
