Problems solved by technology

However, in actual engineering cases, the tension of several steel wire ropes is completely balanced, which is often not 100% realized, resulting in a larger force on the steel wire ropes that are adjusted more tightly, and a smaller force on the steel wire ropes that are loosely adjusted.
When the steel wire rope meshes with the sheave, the vibration generated interferes with each other, which affects the comfort of the elevator operation, and reduces the service life of the steel wire rope. The workload of on-site adjustment and maintenance is also large

Embodiment Construction

[0014] see figure 1 , 3 The wire rope tension automatic balancing rope head device comprises, wire rope rope head 7 (comprising wire rope initial end 71, steel wire rope termination end 72), steel wire rope 9 and pulley 6 for automatic balancing and the pulley seat (comprising car side pulley) that pulley 6 is set Seat 1 and counterweight side pulley seat 2) etc.

[0015] Car side pulley block 1 is fixed on car 3 one sides. The counterweight side pulley seat 2 is fixed on the counterweight 4 side. Wire rope starting end 71 (consistent with traditional rope head) is fixed on an end of car side pulley block 1. The wire rope goes around the traction sheave 5, the guide wheel rope groove reaches the pulley of the counterweight side pulley seat 2 at the other end and returns, bypasses the traction sheave, the guide wheel rope groove, reaches the pulley on the car side pulley seat 1, and winds After passing the pulley on the pulley seat 1 on the car side, return to the pulley on...

Abstract

The invention provides a wire rope tension automatic balancing rope end device capable of automatically balancing the tension of an elevator wire rope so as to improve the comfort degree of elevator operation, prolong the service life of the wire rope and reduce the workload of field adjustment and maintenance. An initial end and a terminal end of the wire rope are respectively fixed on a car side pulley block and / or a counter-weight side pulley block; and a middle section of the wire rope repeatedly bypasses a traction sheave, a pulley and a traction sheave on the car side pulley block, and a pulley on the counter-weight side pulley block.

Description

technical field [0001] The invention relates to a rope end device for automatically balancing the tension of a steel wire rope. technical background [0002] At present, traction elevators for various purposes installed in buildings, according to their main parameters such as load capacity, speed, lifting height, etc., through the calculation of safety rate, generally traction elevators need to be equipped with several steel wire ropes. In this way, in the elevator installation and debugging process, in order to make the elevator run more comfortably, the commissioning personnel need to adjust the tightness of the steel wire ropes, so that the tension of several steel wire ropes is balanced. However, in actual engineering cases, the tension of several steel wire ropes is completely balanced, which is often not 100% realized, resulting in a larger force on the steel wire ropes that are adjusted more tightly, and a smaller force on the steel wire ropes that are adjusted loosel...
