Hoisting device for building construction

Abstract

The invention discloses a hoisting device for building construction. The hoisting device for building construction comprises a supporting frame and a supporting arm, a stand is fixed to the top of thesupporting frame, a first motor and a second motor are fixedly welded to the upper surface of the stand, a large winding drum and a small winding drum are rotationally connected to the top of the stand, an output shaft of the first motor is in transmission connection with the large winding drum through a first belt, an output shaft of the second motor is in transmission connection with the smallwinding drum through a second belt, the supporting arm is fixed to one end of the top of the supporting frame, a roller is rotationally connected to the top end of the supporting arm, a first steel wire rope is wound around the large winding drum, one end of the first steel wire rope is wound around the roller, and a guide rail is fixedly welded to the bottom of the supporting arm. According to the hoisting device for building construction, the small winding drum retracts the second steel wire rope, so that a slider is pulled to move downwards along a sliding groove, at the moment, a hook pulls the first steel wire rope to move downwards, and other tools are not needed for pulling a hoisting rope into a room.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a hoisting device for building construction. Background technique [0002] In modern construction projects, cranes replace manpower to move, lift, carry, and lift, and solve the problem of high-altitude hoisting of objects weighing hundreds of kilograms. They can enter civil elevators for lifting or handling, and can also be completely dismantled and disassembled for human handling. . [0003] When the existing hoisting device is used on the window, due to the limited space of the window, the existing hoist cannot rotate horizontally, and other tools are needed to pull the sling to the house; in order to make the suspension more stable, two hooks are often installed, and the two The horizontal height of each hook cannot be adjusted, and it is easy to cause the center of gravity to shift. For this reason, we propose a hoisting device for building construction. Contents of the in...
