Description
Technical Field
The invention relates to the technical field of a balance compensation chain of a lifting elevator, in particular to a guide device of the balance compensation chain of the elevator.
Background
When the elevator runs, a car of the elevator is connected with an opposite counterweight through a steel wire rope, when the car is on the top floor, the steel wire rope is on the counterweight side, and the weight of the steel wire rope is increased on the counterweight side; when the elevator car is at the bottom layer, the steel wire rope is arranged at the side of the elevator car, the weight of the steel wire rope is increased at the side of the elevator car, and the steel wire rope can generate dynamic unbalance along with the continuous up-and-down movement of the elevator, so that the weight of the steel wire rope needs to be compensated by a compensation chain, the fall of the part is balanced, and the elevator can run stably; at present, in an elevator with a vertical lifting distance of more than 30 meters, a compensation chain is important equipment for ensuring the operation stability and safety of the elevator, and for a car with a higher lifting height and a high speed, the car has the defects that the swing amplitude of the balance compensation chain is too large in the motion process and even can touch other parts in a shaft due to the vibration and the high speed of the car load, so that the balance chain is damaged or other potential safety hazards are caused, and a compensation chain guide device needs to be arranged.
