Safety protection device for elevator

Abstract

The invention discloses a safety protection device for an elevator. The safety protection device for the elevator comprises an iron core, an outer stretching plate, a terminal baffle, a ball head anda fixed block; a brake spring is arranged between the terminal baffle and a brake arm; the terminal baffle is arranged at the right end of the brake arm; the outer stretching plate and the terminal baffle are fixedly connected through a pull rod; the iron core is arranged between two iron plates; a winding wire is arranged on the iron core uniformly; the iron plate and the brake arm are connectedthrough a connecting rod; the ball head and brake rubber are fixedly connected through a brake valve block; the brake rubber is arranged at the left end of the ball head; the ball head and the brake are connected through a connecting bolt; the ball head is arranged at the left end of the brake arm; an electromagnetic box is arranged at the left end of the fixed block; and a radiating fan is arranged between the fixed block and the brake arm. The safety protection device for the elevator applies electromagnet principle, the iron core is electrified to attract the brake arm to work, and the safety protection device for the elevator is sensitive and reliable and can effectively protect the safety of the elevator.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a safety protection device for elevators. Background technique [0002] With the rapid development of my country's economy since the reform and opening up, earth-shaking changes have taken place in the country. There are more and more tall buildings. Elevators are widely used as vertically carrying people. In the existing elevator installation, the driving wheel of the elevator slides The problem has not been effectively solved. When reaching a floor and needing to stop, at this moment due to the huge impact force generated by the inertia, the elevator slides, which poses a safety hazard. Therefore, an iron rod is used to block the driving wheel of the elevator during design. This will easily cause the deformation of the elevator driving wheel. When starting again, the deformation of the elevator driving wheel will cause the elevator to be unstable when rising and fallin...

[0002] With the rapid development of my country's economy since the reform and opening up, earth-shaking changes have taken place in the country. There are more and more tall buildings. Elevators are widely used as vertically carrying people. In the existing elevator installation, the driving wheel of the elevator slides The problem has not been effectively solved. When reaching a floor and needing to stop, at this moment due to the huge impact force generated by the inertia, the elevator slides, which poses a safety hazard. Therefore, an iron rod is used to block the driving wheel of the elevator during design. This will easily cause the deformation of the elevator driving wheel. When the elevator starts again, the deformation of the elevator driving wheel will cause the elevator to be unstable when rising and falling, and there are potential safety hazards. This traditionally designed device can no longer meet the existing market demand.
