Explosion-proof control box for high gas tunnel trolley

Abstract

The invention discloses an explosion-proof control box for a trolley in a high-gas tunnel, which includes a storage mechanism. The storage mechanism includes a protective frame and a protective cover. There are also three air vents at equal distances in the horizontal direction. Support blocks are fixedly connected to the outer surfaces of both sides of the protective frame near the four corners, and support blocks are also fixedly connected to the rear surface of the protective frame near the four corners. In the present invention, through the buffer mechanism, the contact between the external hard objects and the protective frame body can be effectively avoided, thereby effectively preventing the deformation of the protective frame during the actual collision process. At the same time, when the external hard objects touch the buffer plate, the Under the pressure of external hard objects, the buffer plate can effectively drive the buffer frame to get close to the protective frame, and when the buffer frame is close to the protective frame, the buffer spring can effectively reduce the impact of the buffer plate on the protective frame under the extrusion of the buffer frame and the support block. impact.

[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 control boxes of high-gas tunnel trolleys are mostly closed in order to achieve higher protection capabilities. structure, and the actual opening and closing of the equipment is cumbersome, which is not convenient for the installation and maintenance of internal functional components. At the same time, due to the closed structure, the heat generated inside the equipment cannot be effectively discharged, which in turn makes the internal functional components of the equipment run in a high temperature environment for a long time , so that the actual service life is shortened, and the internal circuit functional components are prone to problems. In severe cases, electric sparks will be generated, which will bring serious safety hazards to actual construction. The trolley structure is effectively adjusted for its own structure, so that the explosion-proof control box of the high-gas tunnel trolley cannot be stably installed on different types of trolleys, so that the actual use of the equipment is not good, and when an accident occurs, the existing high-gas tunnel platform The outer protective shell of the vehicle explosion-proof control box is easily directly impacted by external hard objects, causing it to deform, causing its internal functional components to be affected. At the same time, the existing equipment cannot effectively monitor the change of gas content and the internal and external conditions of the equipment. It makes it impossible to warn the construction personnel in advance when the equipment fails or the gas content changes abnormally, so that the actual use effect of the equipment is not good
