The invention discloses an electric rescue barring device for an elevator with a machine room. The electric rescue barring device comprises a barring device main body, an electrical control box electrically connected with the barring device main body, a fixed adjustment screw rod fixedly connected with the barring device main body and a barring connection frame for connecting the barring device main body with an elevator traction machine, wherein the barring device main body comprises a motor, a speed reducer connected with the motor, a speed reducer gear connected with the speed reducer and a barring gear meshed with the speed reducer gear; the barring gear is fixedly connected with a belt wheel of the elevator traction machine; the barring device main body further comprises a speed reducer mounting frame for mounting the speed reducer; the speed reducer mounting frame is connected with the barring connection frame and the fixed adjustment screw rod respectively; the fixed adjustment screw rod is fixedly connected with a cross beam of a traction machine mounting seat. By adopting the electric rescue barring device, the whole barring process is finished by only two workers, so that the problem that multiple workers perform barring in turn is solved; by the adoption of the motor, barring can be automatically controlled, and the barring time is greatly saved.
Description
technical field [0001] The invention relates to the technical field of elevators, in particular to an electric rescue barring device for an elevator with a machine room. Background technique [0002] When the elevator has a trapped person, the traditional elevator rescue method with an organic room is to first open the brake release wrench of the elevator traction machine with an organic room. When it is large, the car will automatically move to the leveling position due to the difference in gravity, and then open the car door to rescue the trapped people; Balanced state, at this time, the car must be forced to move to the leveling position by increasing the external force. The traditional method is to reach the leveling level by operating the elevator with the handwheel of the maintenance rescuer. [0003] At present, many high-end residences generally adopt the design of direct access to the home with a single elevator, that is, one elevator and one household. Only the fi...
