[0016] See also Figure 1-2 The utility model provides a technical solution: a device for grinding and polishing welds of steel structures, comprising a base 1, a grinding roller 2, an adjusting assembly, a mounting seat 5 and a limiting roller 6. The base 1 is a strip-shaped structure as a whole, and a conveying trough 11 is provided on the surface of the base 1, and conveying rollers 12 are arranged side by side in the conveying trough 11; the grinding roller 2 is mounted on the upper part of the base 1 through an adjusting assembly, and the adjusting assembly consists of a fixing frame 3 and an adjusting frame 4, wherein the adjusting frame 4 is arranged on the upper part of the fixing frame 3, and the fixing frame 3 is fixedly arranged on the surface of the base 1; the adjusting assembly is symmetrically arranged on both sides of the conveying trough 11, and both ends of the grinding roller 2 are mounted on the adjusting frames 4 on both sides; the mounting seat 5 is fixedly arranged on the upper part of the base 1, and is symmetrically arranged on both sides of the conveying trough 11, and the limiting roller 6 is transversely arranged on the side of the mounting seat 5 facing the middle surface of the base 1.

[0017] Furthermore, a screw barrel 31 is provided on the upper portion of the fixing frame 3 , and a screw rod is provided on the lower portion of the adjusting frame 4 . The screw rod is fitted into the screw barrel 31 . The screw barrel 31 is driven by a servo motor installed inside the fixing frame 3 .

[0018] Furthermore, a grinding motor is installed inside the adjusting frame 4, and the grinding roller 2 is connected to the output end of the grinding motor; the top of the conveying roller 12 is higher than the surface of the base 1, and both ends of the conveying roller 12 are connected to the wall of the conveying trough 11 through a rotating shaft.

[0019] Furthermore, a sleeve 51 is provided on the side of the mounting seat 5, and the limiting roller 6 is vertically arranged as a whole, and the limiting roller 6 is installed on a C-shaped bracket 61; a telescopic rod 62 is provided on the side of the bracket 61, and the telescopic rod 62 is docked in the sleeve 51 and connected to the electric push rod in the sleeve 51.

[0020] Furthermore, the bottom of the conveying trough 11 is set as an inverted V-shaped guide surface 14, and the middle of the guide surface 14 bulges upward; cleaning ports 13 are set at the four corners of the conveying trough 11, and the cleaning ports 13 are at the lowest end of the guide surface 14.

[0021] Working principle: In actual use, the base 1 is placed flat as a whole, and the steel frame to be polished is placed on the conveying roller 12 in the conveying trough 11; the position of the telescopic rod 62 in the sleeve 51 is adjusted by the electric push rod, thereby changing the position of the bracket 61 and the limiting roller 6 installed in the bracket 61, so that the limiting roller 6 is against the side of the steel frame to prevent the steel frame from deflecting when moving on the conveying roller 12; the servo motor is used to drive the screw barrel 31 to rotate, thereby engaging with the screw, and then adjusting the height of the adjustment frame 4, so that the grinding roller 2 installed between the adjustment frames 4 is pressed against the upper surface of the steel frame; then the grinding motor is started to drive the grinding roller 2 to rotate to grind the steel frame; the staff pushes and pulls the steel frame, so that the weld area is fully polished with the grinding roller 2.

[0022] Adjusting the height of the grinding roller 2 allows grinding of steel frames of varying heights; adjusting the position of the limiting roller 6 allows grinding of steel frames of varying widths. This makes it highly adaptable to steel frames of varying specifications. During the grinding process, the grinding roller 2 maintains a constant height while the steel frame moves horizontally at the same level, ensuring consistent grinding thickness and a smooth surface.

[0023] The waste debris generated during the grinding process falls into the conveying trough 11 and slides to the lower parts of both ends under the guidance of the inverted V-shaped guide surface 14 at the bottom of the trough, and can finally be cleaned up uniformly through the cleaning port 13.
