Problems solved by technology

[0004] However, the traction sheave and the traction rope are important safety components of the elevator. In recent years, higher requirements have been put forward for its detection, accuracy and safety. The installation position of the traction wheel will also be different, and the existing traction sheave is not installed accurately; in addition, the tension of a certain traction rope in the traction sheave may be weakened, causing a safety hazard; finally, due to multiple traction ropes The uneven tension between them will produce a horizontal offset force on the traction sheave itself, resulting in the inclination or even displacement of the traction sheave

Abstract

The invention relates to the field of elevator manufacturing and specifically relates to a novel traction sheave. The novel traction sheave is implemented through the following technical solution: the novel traction sheave comprises a connecting shaft and a main wheel connected to the connecting shaft; a traction rope is connected to the main wheel; the novel traction sheave further comprises a fixing device against the main wheel and used for fixing a position of the main wheel on the connecting shaft, a wheel stabilizing device for preventing the main wheel from side tipping and a detection device for testing the tension of the traction rope; the connecting shaft is provided with length distance scale marks and a plurality of positioning holes. The present invention aims at providing the novel traction sheave; a space between every two of a plurality of traction sheaves may be adjusted conveniently and accurately; the novel traction sheave has good supporting performance, and meanwhile, is capable of detecting the tension of the traction rope in first time.

Description

technical field [0001] The invention relates to the field of elevator manufacturing, in particular to a traction wheel. Background technique [0002] As a common vertical lifting tool, traction elevators are widely used in large commercial buildings or office buildings. Compared with hydraulic elevators, traction elevators have the advantages of high transmission height, high acceleration, and rapid lifting. The use range of traction elevators is also very large. widely. [0003] The traction elevator is different from the hydraulic elevator, its power source comes from the counterweight and the traction device, and the traction device includes a traction wheel, such as the traction wheel disclosed in the patent document with the authorized announcement number CN202912536U, which includes a rope groove, There is a special design for the rope groove, which can detect the amount of wear. [0004] However, the traction sheave and the traction rope are important safety compone...
