Problems solved by technology

The current elevator balance compensation chain guide device is only installed on the counterweight side through the installation bracket, and can only guide one side of the balance compensation chain. For a car with a high lifting height and a fast speed, it will cause balance The compensation chain swings too much during the movement, and may even touch other parts in the hoistway, causing potential safety hazards

Embodiment 1

[0012] see figure 1 , a guide device for an elevator balance compensation chain, comprising a balance compensation chain 1 , a guide device 4 on the counterweight side and a guide device 8 on the car side. One end of the balance compensation chain 1 is fixed on the bottom of the counterweight frame 100 , and the other end is fixed on the bottom of the car frame 200 . Among them, S is the center line of the counterweight, and M is the center line of the car.

[0013] The counterweight-side guiding device 4 is fixed below the counterweight frame 100 . The counterweight side guide device 4 includes a roller device composed of a plurality of rollers 41 surrounding the balance compensation chain 1 and a counterweight side mounting bracket 5 supporting the roller device. The counterweight side mounting bracket 5 is fixed on the counterweight side by expansion bolts 7 on the wall 300 of the well.

[0014] The car side guiding device 8 is fixed below the car frame 200. The car side...

Abstract

The invention discloses a guide device for an elevator balance compensation chain. The guide device comprises the balance compensation chain (1) and a counterweight side guide device body (4). One end of the balance compensation chain (1) is fixed to the bottom of a counterweight frame (100), and the other end of the balance compensation chain (1) is fixed to the bottom of a car frame (200). The counterweight side guide device body (4) is fixed below the counterweight frame (100). The guide device for the elevator balance compensation chain further comprises a car side guide device body (8) which is fixed below the car frame (200). The balance compensation chain (1) is sequentially wound around the counterweight side guide device body (4) and the car side guide device body (8). According to the guide device for the elevator balance compensation chain, the car side guide device body and the counterweight side guide device body are used for guiding and limiting the two sides of the balance compensation chain together, the swing amplitude of the balance compensation chain during high-speed running of a car is effectively reduced, and therefore the balance compensation chain runs more stably and more safely.

Description

technical field [0001] The invention relates to a balance compensation chain of an elevator, in particular to a guide device for an elevator balance compensation chain. Background technique [0002] In the elevator, the counterweight and the car move towards each other under the drive of the traction wire rope. When the car is raised, the counterweight moves downward, and when the car is lowered, the counterweight moves upward. In high-speed elevators, in order to make the car run more smoothly, there is also a balance compensation chain between the car and the counterweight. In the prior art, the elevator system is also equipped with an elevator balance compensation chain guide device for guiding the elevator balance compensation chain. The elevator balance compensation chain guide device includes a roller device and a mounting bracket that rolls with the balance compensation chain. The current elevator balance compensation chain guide device is only installed on the count...
