Problems solved by technology

[0003] The elevator balance compensation chain of the current technology is limited by manufacturing technology and use environment factors, and does not have self-lubricating function, and the outer wrapping material of the elevator balance compensation chain is not flame-retardant or does not meet environmental protection requirements although it is flame-retardant. Manufacturers generally The use of ordinary materials cannot play a role in flame retardancy. Ordinary materials generally contain harmful substances required by the European Union's list of prohibited substances, which cannot meet environmental protection requirements. However, ordinary skeleton layer electric welding anchor chains have not been rust-proofed on the surface of the wire during the manufacture of anchor chains. And lubrication treatment, in the process of use, due to surface rust or other reasons, it is easy to get stuck, causing the working condition of the compensation chain to be bent and blocked, and it is easy to produce gravity deviation, which affects the smooth operation of the compensation chain system

Embodiment 1

[0021] see Figure 1-4 , an elevator balance compensation chain with strong self-lubricating stability, including the first chain ring 1 and the second chain ring 2, the first chain ring 1 and the second chain ring 2 are flexibly socketed, and the first chain ring 1 is close to the second chain ring One end of the chain ring 2 and the end of the second chain ring 2 close to the first chain ring 1 are both sleeved with a collar 3, that is, when the second chain ring 2 rotates relative to the first chain ring 1, the second chain ring 2 is far away from the first chain ring 1. One end of the chain ring 1 will be close to or far away from the first chain ring 1. It can be, but not only, the collar 3 provided at both ends of the first chain ring 1 and the second chain ring 2, the first chain ring 1 and the second chain ring 2 When the two chain rings 2 rotate relative to each other, the first chain ring 1 and the second chain ring 2 rotate in the collar 3, which greatly reduces the...

Embodiment 2

[0023] Based on Example 1, such as Figure 1-4 , the two sides of the collar 3 are fixedly connected with flexible reinforcing ribs 4, the number of flexible reinforcing ribs 4 on each collar 3 is two, and the other end of the flexible reinforcing ribs 4 is connected with the first chain ring 1 and the second chain ring 1 respectively. Both sides of the chain ring 2 are fixedly connected, so that the position of the collar 3 is limited, and the position of the collar 3 can be limited while the first chain ring 1 and the second chain ring 2 can only produce relative rotation without It will produce relative movement, which can reduce the shaking of the compensation chain during the operation of the elevator, which is beneficial to the stability of the elevator during operation. The flexible reinforcing rib 4 is woven by tough material, and the flexible reinforcing rib 4 is soaked in lubricating oil, so that the first The rotation process of the chain ring 1 and the second chain...

Abstract

The invention relates to the technical field of elevator compensation chains, and discloses an elevator balance compensation chain with high self-lubricating stability. The elevator balance compensation chain comprises first chain rings and second chain rings, and the first chain rings and the second chain rings are movably connected in a sleeved manner. According to the elevator balance compensation chain with the high self-lubricating stability, outer barrels, inner barrels and stress ropes are arranged, limiting grooves and limiting rings in the outer barrels and the inner barrels can slide, so that the inner barrels and the outer barrels are rotationally connected, the inner barrels are connected to the two ends of the first chain rings and the second chain rings in a sleeving manner, when the balance compensation chain is used, grabbing swing and rotation can occur, the surfaces of the limiting rings are attached to the surfaces of the groove inner walls of the limiting grooves, the limiting rings and the limiting grooves are located at the middle positions of shaft rings, so that when the shaft rings bear rotating force of the first chain rings and the second chain rings, the positions of the outer barrels and the inner barrels cannot deviate, and the situation that the positions of the rotating joints of the ends of the first chain rings and the ends of the second chain rings deviate when the balance compensation chain operates is effectively avoided.

Description

technical field [0001] The invention relates to the technical field of elevator compensation chains, in particular to an elevator balance compensation chain with strong self-lubricating stability. Background technique [0002] The elevator balance compensation chain is mainly a device suspended between the counterweight and the car to compensate the weight of the accompanying elevator and the wire rope. It is an important safety component of the manned elevator, which can prevent the elevator from rushing to the top and improve the traction balance coefficient of the elevator. [0003] The elevator balance compensation chain of the current technology is limited by manufacturing technology and use environment factors, and does not have self-lubricating function, and the outer wrapping material of the elevator balance compensation chain is not flame-retardant or does not meet environmental protection requirements although it is flame-retardant. Manufacturers generally The use ...
