Embodiment

[0028] A stall-prevention locking mechanism for a driving device of an elevator, such as figure 1 , figure 2 As shown, it is set on the driving device for the elevator. The driving device for the elevator includes a motor 1, a roller 2, a coupling 3 and a roller brake pad 4. The two ends of the roller 2 are respectively connected by two couplings 3 and two Connect to the motor 1 output. Both ends of the roller 2 are respectively provided with a first roller brake pad 41 and a second roller brake pad 41. The locking mechanism includes a brake device 5, a travel switch 6 and a controller. The brake device 5 is arranged on the first roller. On the side of the drum brake pad 41 , there are two braking devices 5 , which are respectively located on the front and rear sides of the drum 2 , and are arranged on the side of the first drum brake pad 41 . The travel switch 6 is set at the shaft coupling 3, the brake device 5 and the travel switch 6 are connected to the controller at th...

Abstract

The invention relates to an anti-falling locking mechanism for the stall of a drive device of a lift. The anti-falling locking mechanism is arranged on the drive device of the lift. The drive device of the lift comprises a motor, a roller, a coupler and roller brake pads. The roller is connected with the output end of the motor through the coupler. The roller brake pads are arranged at the two ends of the roller. The locking mechanism comprises braking devices, a travel switch and a controller. The braking devices are arranged on the side edges of the roller brake pads. The travel switch is arranged at the coupler. The braking devices and the travel switch are both connected with the controller. When the coupler triggers the travel switch when being cut off or loosened, signals of the travel switch are transmitted to the controller, the controller controls the braking devices to be started to lock the roller brake pads, and rotation of the roller is stopped. Compared with the prior art, the anti-falling locking mechanism has the advantages of being compact in structure, capable of saving space, convenient to adjust, good in locking effect and the like.

Description

technical field [0001] The invention relates to an elevator device, in particular to a stall-prevention locking mechanism for a driving device for an elevator. Background technique [0002] The commonly used elevator structure is to drive the roller to rotate through the motor, the conveyor belt is wound on the roller, the roller drives the conveyor belt to run, and the platform is set on the conveyor belt, so the operation of the conveyor belt makes the platform lift and complete the lifting function of the platform. When the coupling between the motor and the roller is disconnected, the elevator stalls, and if the roller continues to rotate, it will cause great danger. Therefore, in order to avoid the phenomenon that the elevator stalls and the roller continues to idle, it is necessary Set a locking mechanism for the roller operation. [0003] The existing lifting and locking mechanism is mainly realized by a stroke switch, which is complex, takes up a large space, and ha...
