The invention discloses a mining safety type vacuum feed switch mechanical lock, belongs to the technical field of mechanical locks for mining safety type vacuum feed switches, and is used for preventing misoperation of a mining safety type vacuum feed switch. The mechanical lock comprises a connecting part, a plugging part and a locking part; one end of the plugging part is connected with the connecting part; the locking part comprises two locking pieces arranged in parallel and a padlock, one end of each locking piece is connected with the connecting part, through holes are formed in the twolocking pieces, the two through holes form a lock hole structure, and the padlock penetrates through the lock hole structure to be connected with the two locking pieces. The mining safety type vacuumfeed switch is simple in structure and fewer in parts, can be directly added and transformed in a mining machine, can effectively avoid the phenomenon that maintenance personnel or other unwanted persons open the mining safety type vacuum feeder switch privately after the simple mechanical lock is added, standardizes field operation of hooking personnel, and ensures the safety and the reliability.
Description
technical field [0001] The invention belongs to the technical field of mechanical locks for vacuum feed switches, is used for preventing misoperation of vacuum feed switches, and relates to a mine safety mechanical lock for vacuum feed switches. Background technique [0002] Mine-used safety vacuum feed switch is mainly used for power transmission and power-off of coal mine underground power supply system. , protectors, relays and control components and other electrical components. The vacuum feed switch is very important equipment. The vacuum feed switch cannot be operated at will, otherwise it will affect the production process. In severe cases, it will cause accidents in the mine. Personnel can also operate, and safety cannot be guaranteed. It is difficult and costly to directly weld a mechanical lock on the door of the vacuum feed switch. At the same time, it is not possible to directly transform the vacuum feed switch in the mine. Contents of the invention [0003] ...
