Description
technical field [0001] The invention belongs to the technical field of elevator maintenance, in particular to a safety pin device for elevator maintenance. Background technique [0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two rigid rails that are perpendicular to the horizontal plane or less than 15° from the plumb line; the safety gear is the safety protection of the elevator. The elevator safety gear device is under the control of the speed limiter. When the elevator speed exceeds the limit speed set by the elevator speed limiter, or when the suspension rope breaks and relaxes, it will emergency stop and clamp the car. A safety device on the car frame; it provides effective protection for the safe operation of the elevator, and is generally installed on the car frame or counterweight frame. [0003] At present, when installing the safety gear in the prior art, inaccurate po...
