Along with the development of the elevator industry, the intelligent transportation requirement of modern buildings is adapted, some elevator manufacturers develop a wide-body car elevator with a rectangular box body, in order to ensure the stable operation of the elevator, a specially-arranged elevator balance compensation chain system needs to be hung at the bottom of the elevator car, the stable and reliable operation is ensured, and the problem of dynamic balance in the elevator lifting process is solved.
The balance compensation chain is commonly used for a car elevator and is mainly used for compensating the weight of a steel wire rope to ensure that the elevator runs stably. When the elevator 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 is at the bottom floor, the wire ropes are on the car side, which adds to the weight of the wire ropes. The fall can be balanced by installing the compensating chain, and the compensating chain is used for compensating dynamic balance, because the steel wire rope has weight, and can generate dynamic unbalance along with the continuous up-and-down motion of the elevator, so the compensating chain is used.
The existing balance compensation chain has the problems that the elevator balance compensation chain is coated by an electric welding anchor chain and a composite material, but the bending diameter is not controlled generally, so that the suspension systematical problem of the compensation chain is caused, namely, the compensation chain cannot form a natural vertical motion curve because the bending diameter is too small, the compensation chain can deviate from a guide wheel in motion to form motion resistance, and the service life of a product is reduced. Therefore, we propose a balance compensation chain and an automatic winding device for a wide car elevator.
