Abstract

The invention discloses a stall detection device and a stall detection method. The stall detection device comprises a first transmission part, a second transmission part connected on a same axis with the first transmission part, a stall detection disc arranged on the first transmission part, a stall detection rod with one end arranged on the second transmission part and the other end located at the same circumferential position together with the stall detection disc, and a photoelectric detection part located on the outer side of the stall detection rod and the stall detection disc; and the photoelectric detection part, the stall detection disc and the stall detection rod are located at the same circumferential position. When the stall detection device in the embodiment of the invention stalls, the first transmission part and the second transmission part generate relative motion, the stall detection rod is in contact with the stall detection disc, and the photoelectric detection part sends a stall signal after detecting that the stall detection rod is in contact with the stall detection disc, so that stall detection is realized. Therefore, an elevator car and a high-low speed brake can be stopped in time when the elevator car has a stall fault, and the safety of passengers and the stability of equipment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a stall detection device and a stall detection method. Background technique [0002] The working principle of the car of the existing jumping machine is that the motor of the car of the jumping machine is connected with the drum coupling, and the car is driven to move by the traction of the steel wire rope. [0003] However, during the working process of the car motor and the reel coupling of the jumping machine, it may be disengaged due to failure or component aging, and the car stall failure may occur, which may easily lead to safety accidents. [0004] Thereby prior art still needs to improve and improve. Contents of the invention [0005] In view of the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a stall detection device and a stall detection method, aiming to solve the problem that safety accidents are easily...
