Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a construction elevator for a building project. Background Art

[0002] Building construction refers to the production activities during the implementation phase of a project. It is the process of constructing various buildings. It can also be said to be the process of transforming the various lines on the design drawings into physical objects at the designated location. It includes foundation construction, main structure construction, roof construction, and decorative construction.

[0003] Patent publication number CN221141027U discloses a construction hoist, which includes a transverse guide rail and a transverse seat. The ends of the transverse guide rail and the transverse seat are connected to each other by a connecting rod. The interior of the transverse seat is rotatably connected to a transverse screw through a bearing. The outer side of the transverse screw is provided with a transverse nut. One end of the transverse seat is fixedly connected to a transverse motor. The device is equipped with a transverse mechanism. When in use, the lifting mechanism is installed in the use position through the transverse mechanism. When the lifting mechanism is inconvenient to lift and transport materials during use, the position of the lifting mechanism can be adjusted laterally through the transverse mechanism as needed, thereby facilitating the lifting of materials to a specific position.

[0004] However, the problem with this device is that the material to be lifted is placed on the lifting seat, and then the lifting screw and lifting nuts are used to lift the material. However, there is only one lifting seat and lifting frame set in the elevator. This results in that in the process of logistics lifting and moving, the material in the lifting seat must be raised to a suitable position and moved out, and then the lifting seat is moved down to the initial position before the material can be continued to be transported to the moving seat, and then the lifting and feeding of the material can be continued. This seriously affects the lifting and feeding of the material, that is, the lifting and feeding efficiency of the material. For this reason, a construction engineering construction elevator is proposed to solve the problem of low lifting and feeding efficiency of the existing construction elevator. Utility Model Content
