Abstract

The invention discloses a seesaw-type rope end balancing device for forcibly driving an elevator, belonging to the technical field of elevators. The seesaw-type rope end balancing device comprises a bearing shaft, U-shaped screws, a bearing seesaw, a shaft sheath, a left-tilting limit protection switch and a right-tilting limit protection switch. In order to achieve the invention, a wire end combination comprising two driving wire ropes for the drum of the main machine of the elevator is respectively fixed at two ends of the seesaw-type device; and the seesaw-type device is mounted in a position depending on the multiplying power of a driving pulley block for forcibly driving the elevator, particularly, the seesaw-type device is mounted at the upper part of a bearing beam of an elevator machine room if the multiplying power of the driving pulley block is selected as an even number, and the seesaw-type device is mounted at the lower part of an upper beam of an elevator car if the multiplying power of the driving pulley block is selected as an odd number, thus achieving the purpose of balancing the rope ends to forcibly drive the elevator.

Description

technical field [0001] The invention relates to a rope head device for a forced-drive elevator, in particular to a seesaw type rope head balance device for a forced-drive elevator, belonging to the technical field of elevators. Background technique [0002] At present, most elevators at home and abroad are traction type. But along with the development of society, the user that elevator is installed in the low-rise building also increases gradually, and the forced drive elevator that is suitable for low-rise develops again thereupon. However, during the operation of the forced drive elevator, due to the unbalanced loading, the uneven force on the driving wire rope and the processing error of the drum will cause the deformation of multiple driving wire ropes, making the length inconsistent, and even exceeding the adjustment range of the spring in the rope head combination. Therefore, the field of elevator technology needs a device that uses other means to compensate and adjus...
