Problems solved by technology

When the compensation rope expands and contracts due to, for example, temperature changes, the compensation rope tensioner and its frame can slide along the tensioner guide rail in a certain range in the vertical direction so that the compensation rope remains tense. Jumping and swinging will not only easily cause damage to the hoistway, but also easily cause the compensation rope to be hooked with other elevator components, affecting the safe operation of the elevator equipment. Therefore, an elevator compensation rope tensioner limiting mechanism is needed to improve the above problems

Abstract

The invention relates to the technical field of elevators, in particular to a limiting mechanism for a compensation rope tensioning wheel of an elevator. The limiting mechanism comprises a bottom plate and a tensioning frame, wherein a cushioning supporting component is arranged in the middle of the base face of a supporting plate in the length direction; limiting rods corresponding to supporting rods are arranged at the bottom of the supporting plate; a first tensioning wheel is arranged in the left side of the tensioning frame; a second tensioning wheel is arranged in the right side of the tensioning frame; a first limiting frame is arranged at the left end of the tensioning frame; a second limiting frame is arranged at the right end of the tensioning frame; and limiting sleeve bases are symmetrically arranged at the left side and the right side of the tensioning frame front and back. According to the limiting mechanism, the stress displacement stability of the tensioning frame can be high through the limiting rods and the limiting sleeve bases; the displacement direction can be guided, the tensioning frame can be effectively prevented from being stressed and deviated, and the overall operation and use stability is improved; and the tensioning frame can be subjected to cushioning supporting through a cushioning supporting component, the stability of the tensioning frame in the stress process is high, and the overall use stability is improved.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to an elevator compensation rope tensioner limiting mechanism. Background technique [0002] Various elevator systems are common in the prior art. One common type is the traction elevator system. This system includes traction machine, traction rope, car, counterweight and corresponding control system, etc. One end of the traction rope is connected to the car and the other end is connected to the counterweight through the traction sheave on the traction machine. The traction machine drives the traction rope through the friction force between the traction rope and the traction wheel, and then drags the car and the counterweight for relative motion. [0003] In order to compensate the weight of the traction rope and other components to make the elevator run stably, it is generally necessary to install a compensation device for the elevator system. Compensation chains are generall...
