Explosion-proof fireproof electromagnetic brake device

Abstract

The invention discloses an explosion-proof fireproof electromagnetic brake device. The explosion-proof fireproof electromagnetic brake device comprises a power supply component and an explosion-proofelectromagnet mechanism, wherein the power supply component supplies power for the explosion-proof electromagnet mechanism, and the explosion-proof electromagnet mechanism is arranged on an electric door machine and used for controlling the opening and closing of an electric door; the device further comprises a shell, a manual opening and closing assembly, a manual releasing assembly and a temperature control releasing assembly; the shell is used for supporting the explosion-proof electromagnet mechanism to work, and the explosion-proof electromagnet mechanism is used for controlling the electric door machine to operate and realizing opening and closing of the electric door; the manual opening and closing assembly is used for controlling the explosion-proof electromagnet mechanism to realize manual opening and closing of the electric door; the manual releasing assembly is installed on the shell and used for manually achieving opening and closing of the electric door; and the temperature control releasing assembly is mounted on the shell side and used for monitoring the temperature and controlling the manual releasing assembly. The explosion-proof fireproof electromagnetic brake device has the beneficial effects that the manual releasing assembly and the temperature control releasing assembly are arranged; meanwhile, a manual release function and a temperature control release function are realized; and the structure is compact and the functions are complete.

Description

technical field [0001] The invention relates to the technical field of electric door machine equipment, in particular to an explosion-proof and fire-proof electromagnetic brake device. Background technique [0002] As a device for automatically controlling the opening and closing of doors and windows, the electric door brake is widely used in all walks of life; it is also reflected in the automatic opening and closing device of the fire door; the application of the electric door brake can prevent the expansion of the fire, or reduce the damage caused by the fire. loss. [0003] At present, there are roughly two types of electric door brakes: one is a mechanical brake; the other is an electromagnetic brake. The hand chain realizes the manual opening and closing function, but cannot realize the manual release function and the temperature control release function. The 2nd, electric door machine brake device is made electromagnetic type explosion-proof brake device, can be wit...

Problems solved by technology

[0003] At present, there are roughly two types of electric door brakes: one is a mechanical brake; the other is an electromagnetic brake. The hand pull chain realizes the manual opening and closing function, but it cannot realize the manual release function and temperature control release function

The second is to make the electric door brake device into an electromagnetic explosion-proof brake device, which can be equipped with a manual crank function, but cannot be equipped with a hand chain, so that the manual opening and closing function cannot be realized, and the manual release function and temperature control release function cannot be realized.
