Abstract
The utility model provides a method of hydraulic cushion system - formula elevator rises and tightly installs reaches, be applicable to marine elevator or rise the impact load of tight device big, receive external factor to disturb the elevator that takes place to beat under the operating mode. The device is including rising by tight subassembly, hydraulic cushion system - subassembly and fixed subassembly. When the device received ascending impact load, the plunger returned and to contract, the cylinder body rebound, and the oil pressure of plunger inner chamber risees, restraines impact load, and buffer spring further compresses, restraines the tight device that rises and shifts up, and simultaneously, pressure oil and buffer spring storage impact energy reach the buffering effect that the elevator rises and tightly installs. This device is effectual to be prevented to rise the tight pulley and takes place to beat receiving impact load or disturbed by external factor, can real -time detection speed limit wire rope because of expend with heat and contract with cold or the long -time wire rope elongation that arouses that uses, real -time detection speed limit rope tensioning force change, prevents that speed limit rope tensioning force is not enough to arouse overspeed governor and safety tongs linkage failure, system compact structure, occupation space is little, and application scope is wide, installation convenient to use.
