Description

Technical Field

[0001] The utility model relates to the field of building materials, in particular to a building material lifting device for construction. Background Art

[0002] Building materials refer to the general term for materials used in civil engineering and construction projects. Building materials play a vital role in construction projects. The quality of building materials directly affects the safety, environmental protection, energy saving, comfort level and service life of the building. During the construction of high-rise buildings, it is usually necessary to use lifting to transport them.

[0003] Existing lifting equipment generally requires workers to drag the building materials in mid-air back into the house after the building materials are lifted up. This not only increases the workload of the workers, but also cannot guarantee safety, making the lifting equipment inconvenient to use. For this reason, we propose a construction material lifting equipment to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a construction material lifting equipment to solve the problems raised in the above background technology.

[0010] In a further embodiment, a symmetrical second support frame is fixedly connected to the outer surface of the first suspension arm, and the upper end of each of the second support frames is commonly connected to the outer surface of the second motor.

[0011] In a further embodiment, a control panel is fixedly connected to the outer surface of the support.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The device utilizes the second motor to drive the second gear to rotate forward and reverse, and the second gear and the first gear are meshed with each other to drive the threaded rod to rotate, and the rotation of the threaded rod drives the second boom to extend and retract. When the boom is extended and retracted, the rotating wheel is driven to rotate through the retraction and extension movement of the lifting rope, and the first motor drives the retraction and extension of the lifting rope at the same time, so as to keep the lifting box at the same horizontal plane, so that when the building materials are lifted to a high place, there is no need for workers to drag the building materials, which avoids the problem of workers stepping on air and ensures the safety of lifting and use.
