Description
Technical Field
The utility model relates to an elevator detects technical field, especially an elevator wire rope testing arrangement.
Background
At present, the elevators at home and abroad are usually driven by a traction machine, and a suspension lifting system of the traction elevator comprises main components such as a traction sheave, a steel wire rope set, a lift car, a balance block system and the like; in the suspension lifting system of the traction elevator, friction force generated by winding each steel wire rope in the steel wire rope group in a groove of a traction sheave provides power for lifting or descending the elevator car; under the regulation of the continuous development of elevator driving technology, the lifting height and the running speed of the elevator are greatly improved, and simultaneously, higher requirements on the safety and the reliability of the elevator are provided.
Theoretically, when the elevator is in use, the stress of each steel wire rope in the steel wire rope group should be the same, and the shape and the size of a groove for winding the steel wire rope on the traction sheave should be the same; in the actual use process, however, the stress of each steel wire rope in the steel wire rope group is different due to various reasons, so that some steel wire ropes are stressed greatly and some steel wire ropes are stressed slightly; the friction between the steel wire rope stressed greatly and the corresponding groove on the traction sheave is relatively large, so that the friction of the groove on the corresponding traction sheave is more severe, the shape and the size of the groove on the corresponding traction sheave are changed after a long time, and the force borne by the steel wire rope stressed greatly in the working process is increased. If the radius of the groove on the traction sheave is reduced by 0.1 mm after the groove is worn, the movement of the steel wire rope is reduced by 0.314 mm when the traction sheave rotates for one circle; taking a building with 20 floors as an example, if the traction sheave rotates about 100 circles, the following steel wire rope needs to move less by 31.4 millimeters, and tests show that the following steel wire rope needs to bear about 3000 newtons more; when the stress of each steel wire rope in the steel wire rope group is uneven, a creeping phenomenon is generated between the steel wire rope with small stress and the traction sheave, and the creeping between the steel wire rope and the traction sheave can cause the abrasion of the steel wire rope and the traction sheave; the higher the floor, the more serious the above situation. Therefore, the steel wire rope which is used for a long time and is stressed greatly is easy to break in the using process, so that the safety accident of the elevator is caused; meanwhile, the steel wire rope with small stress is damaged due to abrasion with the traction sheave, and if the steel wire rope is seriously damaged, the steel wire rope is also broken, so that the safety accident of the elevator is caused.
