A building material lifting device whose safety performance increases step by step with height

Abstract

The invention discloses a construction material lifting device whose safety performance increases step by step with the height. The wire wheel and the transport plate are connected by steel wires. The outer walls of the two side plates of the lifting frame are respectively equipped with automatic locking devices. The safety lock blocks in the automatic locking device are inserted on the two side plates of the lifting frame. In some locking through slots, the safety lock block is concave, and the protruding end of the safety lock block is inserted in the vertically elongated plate and faces the locking through slot. The advantage of the present invention is that it lifts the transport board through two ropes, and as the transport board rises continuously, the safety lock block continuously enters the bottom of the transport board through the engagement of the gears, thereby ensuring the safety of the transport board , there will be no accidental fall phenomenon.

Description

Technical field: [0001] The invention relates to the technical field of building construction equipment, in particular to a building material lifting device whose safety performance increases step by step with height. Background technique: [0002] In building construction, due to the height of the floor, materials will be frequently lifted and transported. In the existing technology, devices that can be directly lifted, such as safety pendants, are often used for how to transport materials to the height. These devices use a It is very dangerous in high-altitude transportation without corresponding safety remedial measures. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and provide a building material lifting device whose safety performance increases step by step with height, which lifts the transport board through two ropes, and as the transport board continues to rise, through The meshing of the g...

Problems solved by technology

[0002] In building construction, due to the height of the floor, materials will be frequently lifted and transported. In the existing technology, devices that can be directly lifted such as safety pendants are often used for how to transport materials to the height. These devices use a There is no corresponding safety remedial measures for direct hoisting with a single rope, which is very dangerous in high-altitude transportation
