One end of the elevator traveling cable is fixed on the lift car, and the other end of the elevator traveling cable is connected with the control cabinet; one end of the compensation chain is fixed on the lift car, and the other end of the compensation chain is fixed on the counterweight, and as the elevator traveling cable and the compensation chain are not provided with a guiding and tensioning device in the process of up-and-down operation along with the lift car, the traveling cable and the compensation chain can swing and rock in the actual up-and-down operation process, so that the lift car has uncomfortable feelings such as abnormal sound in operation, and even causes safety accidents.
In order to solve the above problems, CN2020220425772 discloses an anti-swing device for an elevator trailing cable, wherein a slot channel is formed in a side edge of an elevator shaft, and a cable cavity is formed in a position of the elevator shaft, which is located in the slot channel, so that the trailing cable of the elevator runs in the cable cavity, thereby preventing the trailing cable from being easily scratched, hooked and wound with a traction steel rope or a protruding part on a shaft wall due to large-amplitude swing of the trailing cable directly arranged in the elevator shaft. The method needs to arrange a special trunking channel at the side edge of the elevator hoistway, has higher requirement on the building hoistway, and has low actual operability.
The above is where the present application needs to be addressed.

the compensation chain guide seat is arranged in the middle of the anti-shaking device, and one end of the compensation chain penetrates through the compensation chain guide seat and is fixed at the bottom of the car;
the anti-shaking device drags and goes upward along with the upward movement of the car by taking the main guide rail on the side of the car as a guide carrier through the guide shoe, and goes downward along with the car due to the gravity action when the car goes downward.
The anti-shaking device adopts a rope winding ratio of 2:1, and the running stroke of the anti-shaking device is half of the running stroke of the lift car.
And rollers are arranged on two sides of the cable guide seat, so that abrasion generated when the traveling cable runs is reduced.
And rollers are arranged on two sides of the compensating chain guide seat, so that the friction area of the compensating chain during operation is reduced.
The invention has the following advantages:
1) under the condition of not changing the arrangement of an original shaft, the anti-shaking device moving along with the running of the lift car is designed through the running characteristics of the fixed pulley and the movable pulley by depending on the existing design parts of the lift, the shaking angle of the following cable and the compensation chain is adjusted in real time, and the problem that the shaking angle of the following cable and the compensation chain on the side of the lift car of the high-speed lift is too large due to too large stroke of the lift car is effectively solved;
2) the compensation chain guide seat of the anti-shaking device and two sides of the cable guide seat are provided with rollers to reduce abrasion;
3) the high-speed elevator car runs by adopting a rope winding ratio of 1:1, the anti-shaking device adopts a rope winding ratio of 2:1, when the car runs in the whole running process, the running stroke of the anti-shaking device is always half of the running stroke of the car, and the anti-shaking device adjusts the shaking angle of the traveling cable and the compensation chain in real time according to the running stroke of the car to play a limiting role.
