technical field

The invention relates to the field of elevator manufacturing, in particular to a novel traction wheel.

Background technique

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.

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.

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 the traction sheave itself will produce a horizontal offset force, resulting in the inclination or even displacement of the traction sheave.
