Problems solved by technology

[0003] However, after the elevator balance compensation chain is installed, as the elevator goes up, the weight of the elevator balance compensation chain on the car side gradually increases; as the elevator goes down, the weight of the elevator balance compensation beam on the counterweight side of the car gradually decreases ; Both of these situations may lead to unbalanced loads on the car, increase the wear of the guide device, and affect the comfort of passengers when taking the elevator

Embodiment Construction

[0015] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] see figure 1 A counterweight device for an elevator includes a motor 1 , a transmission gear 2 , a transmission shaft 3 and a counterweight 4 . The transmission gear 2 meshes with the gear on the output shaft of the motor 1 . The transmission shaft 3 is fixedly connected in the central hole of the transmission gear 2 and rotates with the rotation of the transmission gear 2 . The transmission shaft 3 is a threaded rod, and the counterweight 4 is provided with a threaded hole, and the transmission shaft 3 is threadedly connected in the threaded hole of the counterweight 4 . When the motor 1 is running, it drives the transmission gear 2 to rotate, the transmission gear 2 drives the transmission shaft 3 to rotate, and the counterweight 4 moves along the axis of the transmission shaft under the drive of the transmission shaft.

Abstract

The invention discloses an elevator balance weight device, which is mounted on a lift car (6) of an elevator, wherein a servo electric cable (8) is set at the other side provided with a counter weight (7) set on one side relative to two sides of the lift car (6); an elevator balance compensation chain (5) is connected between the lift car (6) and the counter weight (7); the elevator balance weight device comprises a balance weight (4); the balance weight is located on one side relative to the counter weight (7) on the lift car (6); the balance weight (4) can be movably set on the lift car (6) relatively far away from and next to the balance weight (7); and a driving device is mounted on the lift car for driving the balance weight to move along the direction of being far away from and next to the counter weight (7). According to the invention, real-time balance to the reduction and increase in weight of a balance compensation beam can be realized, so unbalance loading of the lift car can be effective; abrasion to a guide device is reduced; and the comfort of a passenger who is taking the elevator can be improved at the same time.

Description

technical field [0001] The invention relates to an elevator counterweight device. Background technique [0002] During the operation of the elevator, the length of the wire ropes on the car side and the counterweight side is constantly changing, which causes the weight of the wire ropes on both sides of the traction sheave to change. 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 influence on the running performance of the elevator when the lifting height of the elevator is not large, but when the lifting exceeds a certain height, it will seriously affect the stability of the elevator operation and endanger the safety of passengers. For this reason, when the hoisting height of the elevator exceeds a certain height, a component with a certain weight must be provided to balance the weight change...
