A compensating rope tensioning mechanism suitable for high-speed elevators

Abstract

A compensating rope tensioning mechanism suitable for high-speed elevators is composed of a compensating steel wire rope and a rope wheel, a tensioning mechanism body and a counterweight steel plate, a guide rail and guide shoe system, an impact buffer system, and a compensating tensioning mechanism body limiting sleeve. It belongs to the technical field of elevator equipment. The compensating steel wire rope runs through the compensating steel wire rope wheel. On the tensioning mechanism body, the wheel axle is fixedly connected to the tensioning mechanism body, and the wheel rotates freely around the wheel axle. The counterweight steel plate increases the mass of the entire mechanism to ensure that the gravity of the mechanism provides sufficient tensioning force for the compensating steel wire rope. The guide rail and guide shoe system is responsible for providing a limiting effect for the entire tensioning mechanism. The impact buffer system improves the shaking phenomenon of the car and reduces the impact on the car. The utility model replaces the operation mode of the traditional compensating tensioning mechanism to limit the counterweight jump that can reach several meters to a range of tens of centimeters, reduce the impact on the elevator car, and can provide sufficient tension for the compensating steel wire rope, and can absorb the excess kinetic energy of the counterweight system when the car is urgently stopped.

Description

Technical Field

[0001] The utility model relates to a compensating rope tensioning mechanism suitable for high-speed elevators, specifically utilizing compensating ropes or compensating cables to ensure that the pressure difference between a car side and a counterweight side is not too large, and belongs to the technical field of elevator equipment. Background Art

[0002] Existing high-speed elevators are all equipped with compensating rope devices. The shock absorption of the compensating rope device is generally achieved by installing rope heads under the car and counterweight, and adding counterweights to the lower ends of the compensating ropes. When the compensating rope tensioning device is running, it plays a certain shock absorption role.

[0003] At present, the main deficiencies of the compensation rope tensioning mechanism are as follows: on the one hand, since the compensation tensioning mechanism is suspended between the car and the counterweight, the compensation tensioning mechanism itself will produce a large shake during the operation of the elevator, which will reduce the riding experience of the car. On the other hand, when the elevator car is in emergency braking when going down, the elevator car stops running, and the counterweight still runs upward at the speed before stopping, until the kinetic energy of the counterweight is consumed by gravity, the counterweight will fall back and rebound again. After multiple rebounds, the counterweight of a high-speed elevator can go up to several meters. During the process, the car will feel a lot of noise and shaking, which will cause the passengers in the car to panic. Utility Model Content

[0004] In view of the above shortcomings, the utility model provides a compensation rope tensioning mechanism suitable for high-speed elevators, and the utility model is realized by the following technical solutions:

[0005] A compensating rope tensioning mechanism suitable for high-speed elevators, comprising a compensating steel wire rope, a rope wheel, a tensioning mechanism main body, a counterweight steel plate, a guide rail, a guide shoe system, an impact buffer system, and a compensating tensioning mechanism main body limiting sleeve, wherein the compensating steel wire rope runs through the compensating steel wire rope wheel; on the tensioning mechanism main body, the wheel axle is fixedly connected to the tensioning mechanism main body, and the rope wheel rotates freely around the wheel axle; the counterweight steel plate consists of inner and outer counterweight steel plates, and is connected to the tensioning mechanism main body by bolts; the guide rail is bolted to the tensioning mechanism main body through a bracket fixing channel steel; the guide shoe is bolted to the tensioning mechanism main body; the impact buffer system consists of a safety clamp, a safety clamp impact block, a buffer spring group, a buffer rubber pad impact plate, a buffer rubber pad, and a buffer rubber block mounting frame.

[0006] Furthermore, the tensioning mechanism body includes two parts, a compensating tensioning mechanism body limiting plate is arranged at the upper part between the two tensioning mechanism bodies, and four compensating tensioning mechanism body limiting sleeves are arranged at the lower part.

[0007] Furthermore, the limiting shaft sleeve of the main body of the compensating tensioning mechanism and the tensioning body are connected by bolts.

[0008] Furthermore, the guide rail includes a guide rail mounting plate and a guide rail mounting plate reinforcement portion.

[0009] Furthermore, the safety clamp is installed on the compensation mechanism body by a safety clamp mounting bolt group.

[0010] Furthermore, the safety clamp impact block is bolted to the guide rail fixing channel steel.

[0011] Furthermore, the buffer spring group is composed of a buffer spring combination mounting plate, a spring limiter, a locking bolt under the guide shaft, a guide shaft, a locking bolt on the guide shaft, and a buffer spring in sequence, and the buffer spring group is connected to the tensioning mechanism body by bolts.

[0012] Furthermore, the buffer rubber impact plate is fixed on the guide rail fixing steel groove through a buffer rubber block mounting frame.

[0013] Furthermore, the buffer rubber pad is connected to the tensioning mechanism body through bolts.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] (1) The safety clamp used in the utility model will hit the safety clamp collision block installed on the guide rail, triggering the safety clamp to clamp the guide rail, which can absorb the excess kinetic energy of the counterweight system when the car stops urgently, thereby improving the safety and comfort of riding.

[0016] (2) The buffer rubber pad impact plate used in the utility model will impact the buffer rubber pad, and finally transfer the remaining energy to the ground and the elevator shaft wall, so that the shock absorption and anti-sway effect of the elevator during operation is more prominent.
