Technical Field

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

[0002] With the continuous development of social science and technology, the floors built on the ground are higher. In order to facilitate the transportation of construction materials to higher floors, construction workers operate the lifting devices used in construction projects to lift the construction materials. Compared with manual handling of construction materials, its advantages are as follows: it effectively reduces the workload of construction workers and greatly improves the efficiency of engineering lifting.

[0003] After searching, a patent document with patent announcement number CN218345066U discloses a lifting device for construction engineering, including a main body mechanism, a lifting mechanism and an adjusting mechanism, wherein the lifting mechanism is located at the upper end of the main body mechanism, and the adjusting mechanism is located at the lower end of the lifting mechanism, and the main body mechanism includes a support base, a universal wheel, a foot brake, a controller and a reinforcement plate, wherein the universal wheel is fixedly mounted at the lower end of the support base, the foot brake is fixedly mounted at the lower end of the universal wheel, the controller is fixedly mounted above the foot brake, the controller is located at the left end of the support base, and the reinforcement plate is fixedly mounted inside the support base. The lifting device for construction engineering, through the installation of the lifting mechanism, has an electric push rod that pushes the placement plate up and down, so as to facilitate the adjustment of the placement plate to tilt and facilitate the loading and unloading of materials by the staff, and the buffer spring can buffer the pressure generated by the lowering, which plays a protective role and improves the use effect of the lifting device for construction engineering.

[0004] However, it still has the following disadvantages in actual use:

[0005] 1. In the existing lifting device for construction projects, when discharging the engineering materials inside the lifting mechanism, first, the L-shaped baffle is opened, and then the electric push rod is operated to extend the electric push rod, thereby tilting the placement plate, and then completing the unloading of the engineering materials on the lifting mechanism. However, there are many operating steps, which will increase the workload of the construction workers;
