Description

Technical Field

[0002] In the current steel structure construction process, due to the high height of the steel structure, the construction workers need to climb to the top to manually tighten the bolts at the top connection of the steel structure. In this case, the use of the bracket is particularly important because it can provide the construction workers with the necessary working platform to ensure the smooth progress of the construction.

[0003] However, there are some problems with the existing bracket design, which greatly affect the safety and efficiency of construction. First, the existing bracket needs to be manually supported when placed to enhance the stability of the bracket. This manual support method not only requires a lot of effort, but also has poor stability. This may cause the bracket to fall due to tilting when the construction workers are working at height, thus causing safety accidents;

[0004] Secondly, due to the stability issues of the existing supports, construction workers tend to feel unsafe when working at heights, which may affect their work efficiency and psychological state;

[0005] Therefore, in order to solve the above problems, a lifting bracket for T-shaped steel structure engineering is needed, which can improve the work efficiency of construction workers and ensure their safety at the same time. Utility Model Content

[0008] As a preferred technical solution of the present invention, the number of pinions is the same as the number of guide posts and supporting toothed plates, and the supporting toothed plates are slidably matched with the guide posts.

[0009] By adopting the above technical solution, the pinion gear, the guide column and the supporting tooth plate are divided into four, each of which is individually meshed and connected, and has the same transmission direction. The supporting tooth plate can be raised and lowered, so that the supporting tooth plate drives the lifting guardrail to rise and fall vertically along the inside of the guide column, which is convenient for adaptation and adjustment according to the installation height.

[0010] As a preferred technical solution of the present invention, a reduction motor is installed on the outer surface of one end of the mounting plate, and the output end of the reduction motor is connected to the driving gear.

[0011] By adopting the above technical solution, the reduction motor transmits the power to multiple gears through the driving gear, so as to synchronously raise and lower the height of the lifting guardrail.

[0012] As a preferred technical solution of the present invention, the driving gear and the driven gear are meshed and transmission-coordinated with the pinion gear.
