Rope end combining device of lift

Abstract

The invention provides a rope end combining device of a lift. The rope end combining device comprises a closed box body with an inner cavity filled with liquid. The box body is provided with a plurality of sliding grooves which are provided with upper openings and are downward concave. A piston capable of sliding vertically along each sliding groove is arranged in each sliding groove. The bottom of each sliding groove is communicated with the inner cavity of the box body so as to enable the space between the bottom of each sliding groove and the corresponding piston to be full of liquid. Each piston is fixedly connected with a connecting rod. The upper end of each connecting rod is fixedly connected with the corresponding piston. Each connecting rod movably penetrates through the bottom of the corresponding sliding groove and the bottom of the box body and extends downward. The lower end, extending downward, of each connecting rod is connected with a rope end used for fixing the end portion fo a steel wire rope. The pistons are equal in cross section area. The rope end combining device of the lift is simple in structure, enables steel wire ropes to be even in stress through using hydraulic damping to automatically balance the pull force of a plurality of steel wire ropes, reduces damage, and prolongs the service life of the steel wire ropes.

Description

technical field [0001] The invention relates to a rope end combination device of an elevator. Background technique [0002] The rope end combination device is generally installed above the car or the counterweight device, and is used to connect the ends of the traction wire rope. It is a group of important load-bearing components on the elevator. The combined strength of the steel wire rope and the rope head combination device should be able to withstand at least 80% of the minimum breaking load of the steel wire rope. In the prior art rope end combination device, the tension adjustment of each steel wire rope is generally realized by manually rotating the adjusting nut to loosen the over-tightened traction wire rope or tighten the over-tightened traction wire rope. This method is time-consuming and labor-intensive. Not only is the accuracy not high, but also the tension of each traction wire rope needs to be adjusted again after the elevator has been running for a period o...

AI Technical Summary

Problems solved by technology

This method is time-consuming and labor-intensive. Not only is the accuracy not high, but after the elevator has been running for a period of time, the tension of each traction wire rope needs to be adjusted again, which is very troublesome.

If the pulling force of the traction wire rope is not adjusted in time, the force on each wire rope will be uneven, the loss of the wire rope will increase, and the service life of the wire rope will be shortened.
