A bidirectional progressive brake safety caliper

Abstract

The invention relates to the technical field of special equipment, and discloses a two-way progressive brake safety tongs, in which a force plate is movably sleeved on the outer surface of the center shaft, the number of force plates is two, and one end of the force plate is fixed A trigger is installed, and the outer surface of the coil drum is in contact with the outer guide rail. When the device is working, the triggers on the upper and lower sides will move simultaneously, so that the brake bar will continue to collide with the trigger on the other side for a second time after hitting the upper trigger, making the braking effect more obvious. At the same time, the brake bar The self-rotating force generated when hitting the upper trigger can be transmitted to the contact position between the lowered trigger and the outer guide rail, so as to avoid the force plate on one side taking the axis of the central axis as the center of rotation due to too severe impact Rotation causes the position of the trigger to deviate and loses the frictional force between the outer guide rail and the whole device loses its effect, which improves the working stability of the device.

Description

technical field [0001] The invention relates to the technical field of special equipment, in particular to a bidirectional progressive brake safety gear. Background technique [0002] As high-rise residential buildings are becoming more and more common nowadays, elevators have become standard equipment for every residential building. Since elevators are often in working condition 24 hours a day and are often in a higher position, the safety of elevator riding has become a top priority. , the top of the current elevator will be equipped with a safety gear, the inside of the safety gear is equipped with a speed limit rope connected to the speed selector, if the elevator accelerates down, the speed limit rope will pull the body of the safety gear to clamp it The speed limit is tight, and the slopes on both sides of the clamp body and the italic body of the shell will produce a self-locking effect through the weight of the elevator, so that the elevator can stop stably and avoid...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing elevator safety tongs proposed in the background technology, the present invention provides a two-way progressive brake safety tongs, which can decelerate in two directions and accelerate to a progressive type, which is not easy to cause injuries to people in the car. It solves the problem that the existing safety gear can only decelerate in one direction and the acceleration is too large during deceleration, which may easily cause injuries to people in the car
