Elevator safety protection clamp

Abstract

The invention discloses an elevator safety protection clamp. The elevator safety protection clamp comprises a support, an upper cavity and a lower cavity, wherein the upper cavity and the lower cavityare formed in the support and connected vertically. The elevator safety protection clamp further comprises an upper clamp body arranged in the upper cavity and a lower clamp body arranged in the lower cavity, and the upper clamp body can move horizontally. The upper clamp body comprises two upper fixing clamp blocks and sliding parts arranged on the two upper fixing clamp blocks, and limiting parts are formed between the sliding parts and the upper fixing clamp blocks. The lower clamp body comprises two lower fixing clamp blocks arranged on the support and movable wedge blocks arranged on thetwo lower fixing clamp blocks, sliding part matching parts matched with the sliding parts are arranged on the movable wedge blocks, and the lower fixing clamp blocks penetrate through the upper end of a partition plate and are clamped in the limiting parts. The elevator safety protection clamp further comprises a pull rod, one end of the pull rod penetrates through the upper side wall of the support, a connecting block is connected to the other end of the pull rod, pin holes inclined upwards are formed in the connecting block, and pin shafts penetrating through the pin holes are arranged on the rear side walls on the lower fixing clamp blocks. The elevator safety protection clamp can effectively prevent digression and is high in safety.

Description

technical field [0001] The invention relates to elevator accessories, in particular to an elevator safety protective clamp. Background technique [0002] In order to prevent the elevator from going up or down too fast and causing accidents, safety gears are generally installed at both ends of the lower beam. When the car overspeeds, the speed limiter set in the elevator shaft moves to drive the safety gear to clamp the track to stop the car. , Safety gear generally includes instantaneous and progressive, so the quality requirements for safety gear are relatively high. The traditional progressive safety gear does not take protective measures, that is, it does not protect the parts that slide with each other, and it is easy to fall under severe vibration. Make mutual sliding braking parts slide out, have certain potential safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an elevator safety protective ...
