Anti-falling device of vertical elevating equipment

Abstract

The invention discloses an anti-falling device of vertical elevating equipment, which comprises a brake control connecting lever and a brake locking mechanism which is arranged in a groove-shaped guide rail, wherein the brake locking mechanism comprises a wedge-shaped inner brake block which is fixedly connected with an elevating platform and two wedge-shaped outer brake blocks which are arranged on the two sides of the wedge-shaped inner brake block respectively; one side, which is close to the groove-shaped guide rail, on each wedge-shaped outer brake block is provided with a friction plate; the two wedge-shaped outer brake blocks are hinged with each other through a wedge-shaped outer brake block pin for a waist-shaped hole on the lower part of the two wedge-shaped outer brake blocks; a tension spring is connected on the wedge-shaped outer brake block pin; the upper end of the tension spring is connected on the wedge-shaped inner brake block; the brake locking mechanism is connected at one end of the brake control connecting lever; the other end of the brake control connecting lever is connected to an elevating pull rod; the elevating pull rod is inserted into the hole of the elevating platform; and pressure springs are arranged in the space between the elevating pull rod and the hole of the elevating platform. By the anti-falling device, the problem of insufficient safety of the elevating platform capable of vertically ascending and descending is solved; and the anti-falling device has a simple structure and low cost and can be flexibly braked.

Description

A fall prevention device for vertical lifting equipment technical field The invention relates to an anti-falling device of vertical lifting equipment guided by grooved guide rails. Background technique The rise and fall of the lifting platform of the vertical lifting equipment is generally driven by wire rope, chain, rack and pinion, gas, hydraulic cylinder, etc. The above driving methods may cause the driving mechanism and the lifting platform to be damaged due to long-term use of materials such as fatigue and fracture. Out of joint, losing the upward force of the lifting platform, the lifting platform often falls freely under the action of gravity, resulting in damage to the lifting platform and the objects on it, casualties and other safety accidents, affecting the normal operation of the lifting equipment. The anti-fall device of the vertical lifting platform has always been a research problem in this industry. At present, it is a good structural form to guide the ve...
