Abstract
The invention discloses a two-node compensating device for wire rope sets of an elevator. The two-node compensating device comprises a body rotatably arranged on a base. Two spherical nodes are symmetrically arranged on the body. Through holes are formed in the centers of the spherical nodes and used for mounting wire ropes. The spherical nodes rotate around the body. A rotating center of the body is arranged on a center face of the body. A rotating center of each spherical node and that of the body are in the same horizontal plane and collinear. The two-node compensating device has the advantages that stress on the six wire rope sets is automatically adjusted and balanced until the stable condition, and accordingly danger caused by unbalanced stress of the wire rope sets of the elevator is avoided, service lives of the wire ropes are prolonged and safety of the elevator is improved.
Description
Technical field
The present invention relates to a kind of improvement of compensating gear of steel wire rope for elevator group, particularly a kind ofly can to regulate the stressed of two groups of steel ropes, and the stressed two node compensating gears reaching identical steel wire rope for elevator group making often to organize steel rope.
Background technology
Current elevator both domestic and external adopts towing machine to drive elevator usually, and towed elevator hangs elevator system and is made up of major parts such as traction sheave, steel rope group, car, balance block systems; Described towed elevator is hung and to be wound around in the groove of traction sheave by the every root steel rope in steel rope group in elevator system and the friction force that produces provides the power of car lifting or decline; Under the adjustment of elevator drive technology development, hoisting depth and the moving velocity of elevator are all greatly improved, and also have higher requirement to the safety and reliability of elevator self simultaneously.In theory, in use, the stressed of the every root steel rope in steel rope group should be the same for elevator, and traction sheave is used for the shape and size of groove of lay winding wire ropes also should be the same; But in actual use procedure, because a variety of causes can make the stressed different of the every root steel rope in steel rope group, some steel rope will be caused so greatly stressed, and some steel rope is stressed little; Friction force between groove on the traction sheave that stressed large steel rope is corresponding with it can be relatively large, the friction of the groove on the traction sheave of its correspondence can be caused so more severe, time one is long, the shape and size of all right groove caused on the traction sheave of its correspondence change, and cause power suffered in stressed large steel rope work increasing.If radius reduces 0.1 millimeter after the groove wearing and tearing on traction sheave, traction sheave often revolves and turns around, and steel rope will lack motion 0.314 millimeter; For the building of 20 layers, traction sheave approximately will rotate 100 circles, so should will lack motion 31.4 millimeters with steel rope, and through overtesting, finding should be how stressed about 3000 Ns with steel rope; When the unbalance stress of in steel rope group steel rope, produce crawl between stressed little steel rope and traction sheave, the wriggling between steel rope and traction sheave can cause the wearing and tearing of steel rope and traction sheave; Floor is higher, and above-mentioned situation is more serious.Thus, the long-time stressed large steel rope used in use, easily ruptures, and causes elevator safety accident; Meanwhile, stressed little steel rope also can, because of the wearing and tearing with traction sheave, occur impaired, if seriously impaired, also can cause the fracture causing steel rope, and cause elevator safety accident; For this reason, we have developed a kind of can adjustment the stressed of two groups of steel rope groups, and the stressed two node compensating gears reaching identical steel wire rope for elevator group making often to organize steel rope.
