Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
As shown in fig. 1-2, a mechanical and electrical locking mechanism of a mining explosion-proof frequency conversion device is mounted on a housing 11 of the frequency conversion device.
As shown in fig. 3-6, the mechanical and electrical locking mechanism includes a clamping plate 2, a rotating chuck 3, a button 5, a guide block 6, a locking fixture block 7, and a travel switch 8; the rotary chuck 3 is fixed at the front end of a switch shaft 4 of a main power supply breaker of the frequency conversion device, the rotary chuck 3 is semicircular, and the edge part is connected with the clamping plate 2 and is connected with a quick-opening door shaft 1 of the frequency conversion device through the clamping plate 2.
The button 5 is arranged on the surface of a shell 11 of the frequency conversion device, the rear end of the button penetrates through the shell 11 to be connected with a locking fixture block 7 in the shell 11, and a boss 71 at the upper end of the locking fixture block 7 is inserted into a groove at the rear end of a switch shaft 4 of the main power circuit breaker; the travel switch 8 is arranged at the lower end of the locking fixture block 7, and the cam position of the travel switch 8 corresponds to the locking fixture block 7.
The guide block 6 is fixed in the shell 11 of the frequency conversion device and at two sides of the locking fixture block 7.
The button 5 is internally provided with a spring 9 and a copper rod 10, the copper rod 10 is arranged in the spring 9, and the tail end of the copper rod 10 is fixedly connected with the locking fixture block 7.
