Fall protection devices for vertical transport of building materials

Abstract

The invention discloses an anti-falling protective device for vertical conveying of building materials, and relates to the technical field of building material conveying equipment. The anti-falling protective device comprises a fixed base, and the top of the fixed base is fixedly connected with an installation plate; the front face of the installation plate is slidably connected with a material box; partition plates are fixedly connected between the two sides of the top of the inner wall of the material box and the two sides of the bottom of the inner wall of the material box; and a moving plate is slidably connected between one side of each partition plate and one side of the inner wall of the material box, and the tops of the moving plates are fixedly connected with lifting plates. According to the anti-falling protective device for vertical conveying of the building materials, the clamping connection effect is greatly improved, the situation that friction plates and elastic wedge-shaped buckles are heavily abraded due to long time using, and serious falling accidents occur is avoided quite well, the effect that the buckles and corresponding clamping plates do not make contact during normal using and are clamped only when accidents happen is achieved quite well, and accordingly, the anti-falling purpose is realized.

Description

technical field [0001] The invention relates to the technical field of building material transportation equipment, in particular to an anti-fall protection device for vertical transportation of building materials. Background technique [0002] In the process of building construction, it is usually necessary to transport building materials to a higher floor for building construction on a higher floor. Hoist from the bottom of the elevator shaft of the building to the corresponding floor. This vertical hoisting method has high hoisting efficiency. Since the hoisting device is usually hung on the output shaft of the motor through a cable, once a power failure occurs, the motor fails or the cable breaks In case of accidents, the car and the materials in the car will fall along the elevator shaft, and the elevator car will fall from a high place, causing a safety accident. [0003] At present, when people design hoisting devices, most of them design friction-type anti-lock contr...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an anti-fall protection device for vertical transportation of building materials, which solves the problem that the existing anti-fall method has a poor clamping effect and cannot realize the buckle and the corresponding clamping plate in normal use. No contact, only when an accident occurs, the buckle will be snapped into the corresponding snap-in plate
