Description
Technical Field
The invention relates to an elevator transmission technology, in particular to a nondestructive elastic elevator rope head combination.
Background
The rope head combination is a connecting part of the hoisting rope and a bearing device such as a car, a counterweight device or a machine room spandrel girder. At present, three rope end combination forms exist: eccentric wire rope head combination, coaxial wire rope head combination and steel belt rope head combination. The first two are matched on a main body with a steel wire rope as a transmission; the third application is matched with the main body with the steel belt as the transmission. No matter how the main body of the elevator is changed, the structure of the elevator is not changed, and only the size of the parts is changed for matching use.
The rope end combination has a spring arrangement in addition to the main function of connecting the transmission body, which gives it a shock-suppressing function. However, there is still a difficulty at present: that is, when the elevator is installed and is in normal operation, the tightening degrees of the steel wire ropes or steel belts (hereinafter referred to as steel wire ropes) of the same elevator are extremely close but not the same, and if the tightening degrees are adjusted again to be consistent, the tightening degrees are very difficult, and the tightening degrees cannot be realized in practice. Because the industry relies on people to wind multiple strands of longer steel wire ropes, the tightening degree of the steel wire ropes is necessarily different. The tension difference is large, and the tightening degree can be realized only by fixing the lift car, the counterweight device and the like and tightening the steel wire rope; the slight tension inconsistency can only be achieved by adjusting the springs compressing the rope hitch, but in this case the rope tension during operation of the elevator is not uniform only in the stationary state of the elevator, due to or as long as the springs of the individual rope hitch are compressed. Thus, the existing products have obvious disadvantages: when a large tension difference value between the steel wire ropes is regulated, the labor and time are wasted; and when small tension differences between the steel cords are adjusted, they cannot be adjusted to be uniform. The result is elevator jitter, noise rise, etc.
