Description

Technical Field

[0002] In the processing of building steel structures, polishing is a crucial process, which directly affects the appearance quality, corrosion resistance and overall performance of the steel structure. With the rapid development of the construction industry, the requirements for the surface finish of steel structures are increasing. Traditional polishing technology can no longer meet the modern high-efficiency and high-quality production needs.

[0003] At present, there are a variety of building steel structure polishing devices on the market, most of which adopt manual or semi-automatic polishing methods. The manual polishing method relies on the experience and technical level of the operator, and has problems such as uneven polishing force, low efficiency and high labor intensity.

Embodiment 4:

[0024] See also Figures 1 to 7 As shown, on a large construction site, a batch of large H-shaped steel beams need to be surface polished. These steel beams are long and have complex surface shapes. Traditional polishing methods are difficult to meet the requirements of efficient and uniform polishing. For this reason, the construction party adopts the polishing device for building steel structures described in this application.

[0025] First, place the mounting platform 1 on a flat ground, ensure that the support column 31 firmly supports the entire device, place the H-shaped steel beam to be polished on the mounting platform 1, and fix it with the clamping plates 35 on both sides of the partition 32, and start the third electric telescopic rod 34 to drive the clamping plates 35 to clamp the steel beam to ensure that it will not move or vibrate during the polishing process.

[0026] The device is started through the control panel 30, and the driving motor 3 drives the driving rod 4 to rotate, thereby causing the arc-shaped electric slide rail 5 to rotate. The sliding block 7 slides in the arc-shaped electric slide rail 5, driving the mounting plate 8 to perform multi-angle adjustment to ensure that the polishing plate 13 can cover all surfaces of the steel beam. The first electric telescopic rod 15 fixes the plug-in block 9 through the limiting hole 18 to ensure the stability of the connecting plate 10 and the polishing plate 13.

[0034] The polishing plate 13 is connected to the connecting plate 10 via the elastic plug 12, and can automatically adjust its position according to pressure changes during the polishing process to ensure the consistency of the polishing effect.

[0035] The first servo motor 22 fixedly connected in the protective box 21 drives the connecting rod 24 to rotate through the transmission rod 23, and the second servo motor 26 fixedly connected in the motor box 25 drives the second electric telescopic rod 28 to adjust the angle through the movable rod 27. The second electric telescopic rod 28 performs telescopic movement, and the output end of the second electric telescopic rod 28 is fixedly connected to the top of the installation box 2, thereby realizing multi-angle adjustment and precise positioning of the installation box 2.

[0036] The camera 29 is disposed in the middle of the surface of the assembly frame 19 and is used to monitor the polishing process in real time to ensure the accuracy and safety of the polishing operation.

[0037] The control panel 30 is arranged on the top of one side of the assembly frame 19 and is used to control the operation of the entire device, including the start and stop and parameter adjustment of components such as the drive motor, servo motor, and electric telescopic rod.
