What is a compensating wire rope

The compensation wire rope is the compensation chain.

Principle: Generally used on the elevator, its structure is an iron chain wrapped with PVC rubber composite material, which is used to compensate for the weight of the wire rope and make the elevator run smoothly.

When the elevator is on the top floor, the wire rope is on the counterweight side, and the weight of the wire rope is more on the counterweight side;

When the elevator is on the ground floor, the wire rope is on the car side, and the car side has more weight of the wire rope.

The compensation chain can be installed to balance this part of the drop, which is used to compensate for dynamic balance, because the wire rope has weight, and with the continuous up and down movement of the elevator, there will be a dynamic imbalance, so the compensation chain is used.

Detailed classification of the compensation chain:

At present, there are the following types of compensation chains on the market:

1. The fiber compensation chain can be used to a ladder speed of 4m s, which can be used in various cold and harsh environments, and is the best compensation chain at present, but it is higher.

2. The all-plastic compensation chain can be used to the ladder speed of 3m s, and the appearance is a cable-like PVC structure, which can achieve a smooth and silent effect when the elevator is used, which is loved by many large elevator companies.

3. Plastic-coated compensation chain, which can be used to a ladder speed of 2m s, has a flat PVC structure in appearance, and its performance is slightly worse than that of all-plastic compensation chain but better than that of rope compensation chain, and it is also cheaper.

4. Wear the rope compensation chain, the structure is to penetrate the hemp rope in the iron chain, the elevator operation noise is large when used, and people have an obvious sense of shaking in the car, but it is cheaper, and it is the most primitive compensation chain.

Quality judgment: The compensation chain can make the elevator run safely and smoothly and achieve the effect of silence and comfort.

There are 3 main characteristics of a poor quality compensation chain:

1. The elevator shakes violently during operation, causing the car to shake and make noise, which greatly reduces the passenger experience;

2. Short service life, poor flexibility, not cold-resistant, easy cracking of the outer coating, violent shaking after cracking, etc.;

3. Poor strength and instability, easy to cause chain breaking accidents.

Definition of elevator balance compensation chain: the car used to connect the elevator with the counterweight, balance the weight of the traction rope and the accompanying cable, and balance the components that play a balancing role in the operation of the elevator.

During the operation of the elevator, the length of the wire rope on the car side and the counterweight side is constantly changing, which causes the change of the weight of the wire rope on both sides of the traction wheel. When the car is located at the lowest station, most of the weight of the wire rope acts on the car side; When the car is located at the highest deck station, most of the weight of the wire rope acts on the opposite side.

This change has little impact on the operation performance of the elevator when the elevator lifting height is not large, but when the lifting exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers.

For this reason, when the lifting height of the elevator exceeds a certain height, the component with a certain weight must be set up to balance the weight change caused by the height change, which is the elevator balance compensation chain.

It is used to compensate for the weight of the wire rope and make the elevator run smoothly.

When the elevator is on the top floor, the wire rope is on the counterweight side; When the elevator is on the ground floor, the wire rope is on the car side. That is to say, with the continuous change of the weight of the elevator up and down, with the continuous up and down movement of the elevator, the empty eggplant will produce a dynamic imbalance;

The role of the compensation chain compensates for this imbalance. When the wire rope moves to the counterweight side, the compensation chain moves to the car side, and when the wire rope moves to the car side, the compensation chain moves to the counterweight side. This serves as a compensatory.

When the elevator is overweight or out of control, the elevator compensation chain will play a protective role to reduce the dynamic imbalance.

Acts as a cushioning stretch at 8 to extend the whole piece of PVC wrap with a specific gravity of about 300.

You're talking about the compensation chain, which is to compensate for the weight of the wire rope, and only high-rise elevators need to be used. Imagine that a 30-story elevator, when the elevator reaches the first floor, how long the wire rope above its head has to be, how heavy is such a long wire rope, when the traction machine pulls the elevator from the first floor down to the highest floor, the wire rope above the elevator continues to shorten and become lighter, if the traction machine can speak, it will definitely scold, and it will be heavy and light. Therefore, people add a few iron chains with the same weight as the wire rope under the counterweight and under the car to balance, and the other principles are the same.

Supplement According to the outline of the elevator operation and maintenance training materials for special personnel, when the ladder speed is greater than that, the rope compensation method with a tensioning device needs to be installed.

The weight balance system is mainly composed of counterweight and weight compensation devices. The main function of the system is to balance the weight of the car relatively, and to keep the weight difference between the car and the counterweight within the limit in the elevator work, so as to ensure the normal traction transmission of the elevator.

An elevator refers to a permanent transportation equipment that serves a number of specific floors in a building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line.

There is also a stepped type, and the tread plate is mounted on the track for continuous operation, commonly known as escalator or moving walk. Stationary lifting equipment serving the specified floors. A vertical lift has a car that runs between at least two rows of rigid rails that are vertical or have an inclination angle of less than 15°.

The utility model relates to a high-rise high-speed elevator compensation device, one end of the compensation rope is fixedly connected with the lower part of the counterweight, the other end is fixedly connected with the lower part of the car by the compensation rope tensioning device, wherein the compensation rope adopts a steel wire rope, the compensation rope tensioning device mainly comprises a tensioning rope pulley and a tensioning weight block, the tensioning rope sheave has a large groove spacing that is used for the tensioning and guiding of the compensation rope, the compensation rope layer is wound in the wheel groove, and one end of the compensation rope is provided with a rope end adjusting device that is used for adjusting and balancing the tension of the compensation rope. The utility model discloses a beneficial effect that: the utility model adopts steel wire rope as a compensation rope, comprises rope end adjusting device, belt rope wheel tensioning device, monitoring device etc., greatly improves the smoothness of compensation wire rope in elevator operation process, eliminates the potential safety hazard of traditional compensation device, thereby improves the running performance and safety performance of elevator.

There is no difference, it is related to the length of the wire rope, and the compensation chain is used to compensate the weight of the wire rope. Therefore, the low-rise elevator does not use the compensation chain. According to the floor, that is, the length of the wire rope, the middle and high-rise elevators choose a compensation chain that matches the weight of the wire rope.

The compensation chain is generally made of iron chains, and hemp rope is worn in the middle to reduce the collision sound caused by friction. There are also. 7335
