High-gas tunnel trolley explosion-proof control box

Abstract

The invention discloses a high-gas tunnel trolley explosion-proof control box. The explosion-proof control box comprises a storage mechanism; the storage mechanism comprises a protective frame and a protective cover; three ventilation openings are formed in the outer surfaces of two sides of the protective frame respectively in the horizontal direction at equal intervals; three ventilation openings are also formed in the rear surface of the protective frame in the horizontal direction at equal intervals; supporting blocks are fixedly connected to the positions, close to four corners, of the outer surfaces of the two sides of the protective frame; and supporting blocks are also fixedly connected to the positions, close to four corners, of the rear surface of the protective frame. Accordingto the explosion-proof control box, through the arrangement of a buffering mechanism, contact between external hard objects and main body of the protective frame can be effectively avoided; further, the deformation of the protection frame in the actual collision process is effectively prevented, so deformation of the protective frame in the process of actual impact can be effectively prevented; and meanwhile, when an external hard object touches a buffer plate, the buffer plate can effectively drive a buffer frame to be effectively close to the protective frame under the pressure of the external hard object, and in the process that the buffer frame approaches the protective frame, buffer springs can effectively reduce the impact force of the buffer plate on the protective frame under the extrusion of the buffer frame and the supporting blocks.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof control box equipment, in particular to an explosion-proof control box for a trolley in a high-gas tunnel. Background technique [0002] The shell of the explosion-proof control box is made of steel plate welding or cast aluminum alloy or 304 stainless steel die-casting, and the surface is electrostatically sprayed with high voltage. Install explosion-proof buttons, explosion-proof components, explosion-proof signal lamps, explosion-proof transfer switches and explosion-proof instruments and other explosion-proof components and common electrical components such as AC contactors, thermal relays, temperature controllers and various functional modules. Instruments, etc. are all explosion-proof components, and the internal components of the control box are arranged according to the requirements of users, which can realize multiple functions. However, in the prior art, the explosion-proof contr...
