The invention discloses a spark-proof and explosion-proof elevator safety gear wedge block, and belongs to the technical field of elevator protection, the spark-proof and explosion-proof elevator safety gear wedge block comprises a bottom plate, mounting plates are fixedly welded to the two sides of the upper end of the bottom plate, threaded columns are rotatably mounted in the middles of the surfaces of the mounting plates, and a fixing seat is rotatably mounted on one side of each threaded column; a first moving block capable of moving up and down is arranged on one side of the fixing base, a second moving block capable of moving along the inclined face of the first moving block is arranged on one side of the first moving block, protection mechanisms are arranged on the two sides of the second moving block and the two sides of the mounting plate, and a limiting nail is connected to the surface of the mounting plate in an inserted mode and fixedly connected with one side of the fixing base. On the basis that falling prevention of the dry shaft elevator is achieved, a certain spark-proof effect can be achieved, fires caused by violent friction are prevented, a certain protection effect can be achieved, and the situation that built-in parts are collapsed and overflowed under violent friction, and normal use of surrounding devices is affected is prevented.
