High-speed elevator compensation rope tensioning device

Abstract

The invention discloses a high-speed elevator compensation rope tensioning device. The device comprises a mounting bottom plate, a front guide rail, a rear guide rail, a guide wheel box, a damping buffering mechanism and a group of compensation ropes; the mounting bottom plate is fixed at the bottom of an elevator shaft pit; the middle of the guide wheel box in the length direction is simultaneously in direct sliding fit with the front guide rail and the rear guide rail at the position of a receding cavity of the guide wheel box, a plurality of counterweight plates are arranged at the lower part of a guide wheel box cavity in the length direction of the guide wheel box cavity in an overlapped state, and compensation rope wheels are arranged at the positions, corresponding to the positionsabove the counterweight plates, at the left end and the right end of the guide wheel box cavity correspondingly; the part, located at the position corresponding to the position of the middle of a guide rail connecting cross beam, of the damping buffering mechanism is arranged on a guide wheel box top plate of the guide wheel box and is connected with the middle of the side, which faces downwards,of the guide rail connecting plate; and one ends of the group of compensation ropes are connected with the lower part of a car, the middle parts of the group of compensation ropes sleeve the compensation rope wheels, and the other ends of the group of compensation ropes are connected with a counterweight block. According to the device, the structure is simplified, and manufacturing and assemblingare convenient; the space occupation of the elevator shaft pit is reduced; and the safety is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of elevator components, and in particular relates to a high-speed elevator compensating rope tensioning device. Background technique [0002] The aforementioned high-speed elevator means that the running speed of the elevator car is above 6m / s. Because the rope swing (rope throwing) phenomenon often occurs during the operation of the elevator car, that is, the swaying phenomenon of the traction wire rope occurs. The swaying of the traction wire rope will affect the running stability of the elevator car and even cause failure. Therefore, according to the design specifications, for Vertical up and down elevators with a running speed of the elevator car greater than 3m / s are usually equipped with a compensation rope, which balances the weight of the traction wire rope. In order to make the compensation rope run stably under the condition of guidance, the elevator compensation rope tensioning device is generall...

Problems solved by technology

But this CN204528997U following shortcoming: one, because it respectively connects a main girder at the left end and the right end of sub-beam, respectively connects the upper end of a guide rail at the two ends of two main girders, the lower end of guide rail is fixed with installation base plate, in two main girders A damping buffer is connected to the middle of the beam, so there are two main beams, four guide rails, and two damping buffers, which significantly increases the complexity of the structure, which is not conducive to manufacturing and assembly. , is also not conducive to reflecting the economy; secondly, because the plurality of stacked weight plates located under the guide wheel box (the patent is called "counterweight") forms a cross-staggered relationship with the guide wheel box and the two weight plates Both ends protrude significantly from both sides of the guide wheel box, thus occupying a large space in the pit of the elevator shaft
