Problems solved by technology

[0008] In order to overcome the problem existing in the prior art that when the elevator is running at high speed, the use effect and performance of the elevator compensation chain are not good, which will limit the lifting speed of the elevator when it is rising, the bearing load is small, it does not have good suspension verticality, and it is easy to twist problem, the present invention provides an all-plastic elastic flame-retardant elevator balance compensation chain

Embodiment 2

[0037] Such as Figure 5 Shown: On the basis of Embodiment 1, both the first sub-metal chain 31 and the second sub-metal chain 32 of this embodiment are also provided with a chain connection device.

[0038] Specifically, such as Figure 5 As shown: the chain connection device as a whole is a horizontal Z-shaped structural member 4, and the length of the Z-shaped structural member 4 is set to be 0.5 to 0.8 times the length between the two alternate chain rings; preferably, the Z-shaped structural member 4 The length is set to 0.6 times of the length between the two alternate chain rings. The chain connecting device is designed as a Z-shaped structural part, mainly considering the stress of the connecting parts. Since the connecting parts play a role of reinforcement between the chains again, the chain itself is extremely difficult to break, which greatly increases the safety factor, and Improve the stability of the compensation chain when the elevator is running; also consid...

Abstract

The invention provides an all-plastic elastic flame-retardant elevator balance compensation chain, which includes a metal chain, the metal chain is covered with a wrapping layer, and a sheath is arranged outside the wrapping layer. The metal chain is composed of two sub-metal chains. The sliver metal chains are respectively a first sub-metal chain and a second sub-metal chain, and the second sub-metal chain is fixed on the first sub-metal chain in a winding manner. In the present invention, the conventional single metal chain is designed as a combination of two sub-metal chains, which does not limit the lifting speed of the elevator when it is rising, has a large load, has good suspension verticality, is not easy to twist, and the quality of a single metal chain is improved. Increase, to a certain extent, reduce the time cost and operating cost.

Description

technical field [0001] The invention relates to the technical field of elevator accessories, in particular to an all-plastic elastic flame-retardant elevator balance compensation chain. Background technique [0002] The elevator balance compensation chain is mainly used to connect the elevator car and the counterweight, balance the weight of the traction rope and accompanying cables, and is a component that balances the operation of the elevator. Generally, during the operation of the elevator, the lengths of the steel wire ropes on the car side and the counterweight side are constantly changing, which causes changes in the weight of the steel wire ropes on both sides of the traction sheave. When the car is at the lowest floor, most of the weight of the wire rope acts on the side of the car; when the car is at the highest floor, most of the weight of the wire rope acts on the counterweight side. This change has little effect on the operating performance of the elevator when...
