The invention relates to an electromagnet manual release device for a brake, belonging to the elevator technical field; the electromagnet manual release device comprises a shell, a release shaft, a central spring, a positioning screw, a position limiting screw and two groups of coils, iron cores, silencing pads, armatures and push rods with the same structure, wherein, the shell is a cylindrical symmetric structure, the position limiting screw is arranged in the center of the shell and clamped with the release shaft, the positioning screw is arranged in the center of the shell and tightly contacted with the release shaft, a first coil and a second coil are symmetrically arranged in the shell along the direction of a shaft line of the shell, the first coil and the second coil are connectedwith an external power supply in series, a first iron core and a second iron core are symmetrically fixedly arranged at the both ends of the shell, the central spring is arranged in the center in theshell, the two ends of the center spring are respectively arranged in spring holes which are arranged at the front ends of a first armature and a second armature, a first push rod and a second push rod are respectively press-fit with the first armature and the second armature and then sequentially penetrate the shell, the coils, the silencing pads and the iron cores. The electromagnet manual release device can effectively prevent the misoperation and is characterized by safety and convenience.
Description
technical field [0001] The invention relates to a device in the technical field of an elevator traction machine, in particular to an electromagnet manual release device for a brake. Background technique [0002] With the application and further development of various lifting equipment in modern society, more and more attention has been paid to their safe operation and the control of their safe state. However, the brake electromagnet on the driving device of traditional lifting equipment is provided with a manual release device. Since this device does not have a mechanism to prevent random manual release, anyone can arbitrarily pull the manual release device, causing the drive device to be in an idle state. In the free state of braking, the driving device will cause the object to be lifted to move in the direction of gravity caused by the imbalance due to the imbalance of the mass of the system itself. Once this movement is formed, its speed change will be determined by the a...
