Material lifting device for construction projects

Abstract

The invention discloses a material lifting device for construction projects in the technical field of the construction projects. The material lifting device comprises a bottom plate, wherein the top of the bottom plate is symmetrically fixed with two sets of mounting side walls, a rotary shaft is arranged between two sets of the mounting side walls in a penetrated mode, the rotary shaft and each set of the mounting side walls are movably connected by a bearing, the right side of the mounting side wall at the right is fixedly connected with a motor mounting table, and the top of the motor mounting table is provided with a first rotating motor. The invention has strong safety in that on one hand, a lifting plate is driven to move up and down to realize the purpose of lifting by the cooperation between screw rods and inner threaded sliding blocks; on the other hand, the lifting plate is pulled by a taken-pulling wire which is driven by a taken-up wire wheel for insurance operation. When the taken-pulling wire is fractured or screw rods and inner threaded sliding blocks are broken, safe incidents can not happen due to the direct falling of the lifting plate. By means of clamping and fixing devices, materials can be clamped and fixed by the device, so that the safe incidents can be avoided due to the slide falling of materials.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a material lifting device for construction engineering. Background technique [0002] Construction engineering refers to the engineering entity formed through the construction of various housing buildings and their ancillary facilities and the installation activities of supporting lines, pipelines and equipment. Among them, "housing construction" refers to projects that have roofs, beams, walls, foundations, and can form internal spaces to meet people's needs for production, living, learning, and public activities. [0003] Material is a professional term in the field of production in our country. Production enterprises are used to transfer all materials (whether they come from means of production or means of living), fuel, parts, semi-finished products, outsourced parts, and leftovers that are inevitably generated in the production process, other than the final...

Problems solved by technology

[0006] The object of the present invention is to provide a kind of material lifting equipment for construction engineering, to solve the problem that most of the existing material lifting equipment proposed in the above background technology have a low safety factor, and most of them use pull ropes for lifting, which have poor stability and If the stretching breaks, it is very easy to cause a safety accident. The existing material lifting equipment has poor shock absorption performance, and most of them do not have the function of clamping and fixing the material. During the process of lifting the material, the material is prone to slipping, which is an extremely dangerous problem.
