Elevator balance compensation chain with high self-lubricating stability

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 ...

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
