Two-way progressive brake safety caliper

Abstract

The invention relates to the technical field of special equipment, and discloses a two-way progressive brake safety caliper. The outer surfaces of central shafts are sleeved by stress plates in a movable mode, and the number of the stress plates is two. One end of each of the stress plates is fixedly provided with a trigger. The outer surfaces of coil cylinders are in contact with an outer guidingrail. When the caliper works, the triggers at upper and lower sides move simultaneously, so that brake bars continue to collide with the triggers on the other side for a second time after hitting theupper triggers, which makes the braking effect more obvious. At the same time, the force produced when the brake bars hit the upper triggers and making the brake bars rotate can be transmitted to thecontact positions between the lower triggers and the outer guiding rail, so as to avoid the problem of excessive impact which causes the rotation of the stress plates on one side with the axis of thecentral shaft as the rotation center, the deviation of the positions of the triggers, and the loss of the friction force between the triggers and the outer guiding rail, which makes the whole caliperineffective. The stability of the caliper is improved.

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] In view of the shortcomings in the use of the existing elevator safety gear proposed in the background technology, the present invention provides a two-way progressive brake safety gear, which can decelerate in two directions and accelerate to a gradual 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
