Building material lifting device with safety increased stage by stage along with height

Abstract

The invention discloses a building material lifting device with safety increased stage by stage along with height. The building material lifting device comprises a lifting frame. A main rotating shaftis rotationally arranged between the upper ends of two side plates of the lifting frame. Wire winding wheels are arranged at the two ends of the main rotating shaft. The wire winding wheels are connected with a conveying plate through steel wires. The outer surface walls of the two side plates of the lifting frame are each provided with an automatic locking device. Safety locking pieces in the automatic locking devices are inserted in locking through grooves in the two side plates of the lifting frame. The safety locking pieces are each in a concave shape. Protruding ends of the safety locking pieces are inserted in vertical lengthening plates and are right opposite to the locking through grooves. The building material lifting device has the advantages that the conveying plate is lifted through two ropes, when the conveying plate continuously ascends, the safety locking pieces continuously goes into the lower side of the conveying plate through meshing of gears, and therefore the safety of the conveying plate is ensured, and no accidental falling phenomenon can happen.

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
