Problems solved by technology

Once wear occurs, the brake disc can be replaced, but the brake of this structure still cannot be used under high load
And there is no locking structure after the braking stops, which is a kind of wear and tear for the braking device, and there are potential safety hazards

Abstract

The invention discloses a traction wheel of an elevator. The traction wheel is characterized by comprising a tubular wheel body and a hollow shaft sleeve which is coaxially arranged with the wheel body; the wheel body and the shaft sleeve are connected through a plurality of spokes distributed in the direction vertical to the circumferential direction of the wheel body; two protective plates are arranged on the wheel body; the protective plates divide the wheel body into a braking section and a sheave section; a braking device is arranged on the braking section in a sleeving manner; the braking device comprises a fixed plate, brake pads and hydraulic rods; the brake pads are arc-shaped structures; one ends of the brake discs are movably connected with the fixed plate; the other ends of the brake discs are movably connected with extension rods of the hydraulic rods; the hydraulic rods are fixedly arranged on the fixed plate; and the brake pads can be pressed towards the braking section or separated from the braking section under the action of the hydraulic rods.

Description

technical field [0001] The invention relates to the field of elevator equipment preparation, in particular to an elevator traction sheave. Background technique [0002] The traction elevator is applied to the longitudinal transportation of high-rise buildings because of its simple structure and convenient use. With the improvement of people's living standards, there are more and more high-rise buildings, and traction elevators are also used more and more widely. [0003] The structure of the traction elevator is that the traction machine as the main power source drives the car to run through the traction sheave and the steel cable wound on the traction sheave. Therefore, a deceleration device is also provided on the traction sheave, which is used to brake the traction sheave when the car approaches the target leveling floor. The traditional braking device acts directly on the traction sheave, once the traction sheave wears too much, it must be replaced, the cost is high an...
