Description

Technical Field

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

[0002] Lifting equipment for construction projects plays a vital role in the construction industry. Lifting equipment can lift heavy objects to a certain height through a lifting mechanism, making it convenient for various installation and assembly work on the construction site. For the transportation of large building materials such as steel bars, concrete slabs, cement, glass, etc., lifting equipment can solve the height and distance problems that cannot be reached by manual transportation, greatly improving work efficiency.

[0003] According to a construction lifting equipment disclosed on the patent website (authorization announcement is CN 220449511U), "a construction lifting equipment includes a first support plate, a second support plate, a support rod, a guide rail, a slider, a bearing box, a wire rope and a retractable wire assembly. The plane where the second support plate is located is parallel to the plane where the first support plate is located. The support rod is connected between the opposite surfaces of the first support plate and the second support plate."

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During use, the utility model controls the operation of the wire-reeling and -release assembly to enable the wire rope to complete the wire-reeling or wire-release action, thereby driving the carrying box to move, thereby completing the lifting work. During the movement of the carrying box, the guide rails and sliders on both sides of the carrying box can play a role of guiding support. However, during actual use, the wire-reeling or wire-release action is completed by the wire-release assembly, thereby driving the carrying box to move. During use, the wire rope of the wire-release assembly is prone to loosening, resulting in an excessively fast rotation speed of the winding roller, which can easily cause the carrying box to fall, which is quite dangerous and thus creates a danger. Therefore, it is necessary to improve a lifting equipment for construction projects. Utility Model Content
