Description

Technical Field

[0001] This application relates to the technical field of welding slag cleaning, and in particular to a welding slag cleaning device for H-shaped steel column processing. Background Technology

[0002] H-shaped steel columns are characterized by their reasonable cross-sectional shape and excellent mechanical properties. With wider flanges and relatively thinner thickness, they can effectively withstand bending moments and shear forces, while the web mainly bears shear forces. This structure makes H-shaped steel columns perform well in terms of load-bearing capacity and stability, and can save steel consumption and reduce structural weight while ensuring structural safety.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following defects: In the prior art, when welding H-shaped steel columns, welding slag remains on their surface. If this slag is not cleaned, it will hinder the tight bonding between the coating and the steel surface during subsequent anti-corrosion coating processes, thereby reducing the protective performance of the coating. Utility Model Content

[0004] In order to clean the welding slag on the surface of H-shaped steel columns, this application provides a welding slag cleaning device for H-shaped steel column processing.

[0005] This application provides a welding slag cleaning device for H-shaped steel column processing, which adopts the following technical solution: including a base plate, a conveying roller fixedly connected to the top of the base plate, a fixed box fixedly connected to the side of the top of the base plate close to the conveying roller, a fixed block fixedly connected to the side of the top of the base plate away from the conveying roller, and a limiting rod fixedly connected to the top of the fixed block; A grinding roller is provided above the limiting rod, a rotating disk is fixedly connected to the top of the grinding roller, a sealing box is provided on the left side of the rotating disk, a push plate is slidably connected to the inner wall of the sealing box, and an air blowing pipe is fixedly connected to the left side of the sealing box.

[0006] Optionally, a motor is fixedly connected to the front of the fixed box, and a bidirectional threaded rod is fixedly connected to the output end of the motor via a coupling. A limiting plate is fixedly connected to the inner wall of the fixed box.

[0007] Optionally, the limiting plate has a rotating hole on its front side, the inner wall of the rotating hole is in contact with the middle of the outer wall of the bidirectional threaded rod, and a moving block is threadedly connected to the outer wall of the bidirectional threaded rod.

[0008] Optionally, the top of the movable block is fixedly connected with a pulley gripper, and the number of pulley grippers is two, which are symmetrically arranged with the limiting plate as the center.

[0009] Optionally, a connecting rod is fixedly connected to the right side of the pulley gripper on the back side, and an assembly plate is fixedly connected to the right side of the connecting rod. The bottom of the inner wall of the assembly plate is rotatably connected to the bottom of the grinding roller, and a rotating groove is opened on the top of the assembly plate. The inner wall of the rotating groove is rotatably connected to the top of the outer wall of the grinding roller.

[0010] Optionally, a fixed column is fixedly connected to the top of the rotating disk, a movable rod is in contact with the outer wall of the fixed column, the left side of the movable rod is fixedly connected to the right side of the push plate, and a one-way valve is fixedly connected to the right side of the push plate.

[0011] Optionally, a limiting groove is provided at the bottom of the moving rod, and the inner wall of the limiting groove contacts a limiting block.

[0012] In summary, this application includes the following beneficial technical effects: 1. This utility model, by setting up components such as grinding rollers, a sealing box, and a push plate, uses two grinding rollers to grind the welding slag on the H-shaped steel column. While the grinding rollers are rotating, the push plate moves back and forth in the sealing box via a rotating disk, compressing the gas in the sealing box into the air blowing pipe and spraying it out. Since the air blowing pipe is aligned with the grinding position, the welding slag that has been ground and fallen on the surface of the H-shaped steel column can be cleaned. This device can grind the welding slag on the surface of the H-shaped steel column, and at the same time, it can clean the welding slag that has fallen on the surface during grinding, so as to prevent the welding slag from affecting the subsequent anti-corrosion coating process of the H-shaped steel column.

[0013] 2. This utility model, by incorporating components such as a motor, a bidirectional threaded rod, and moving blocks, places the H-shaped steel column on the conveying roller. The motor then starts, causing the bidirectional threaded rod to rotate counter-clockwise. This counter-clockwise rotation drives two moving blocks to move synchronously in opposite directions until both pulleys and grippers contact the surface of the H-shaped steel column, clamping it and allowing the column to move under restricted conditions. This device not only restricts H-shaped steel columns of varying widths but also prevents displacement or misalignment during grinding, thus avoiding any impact on the grinding effect.

[0016] The following is in conjunction with the appendix Figures 1-4 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] This application discloses a device for cleaning weld slag during the processing of H-shaped steel columns. For example... Figure 1 , Figure 3 , Figure 4 As shown, it includes a base plate 1, with a conveyor roller 11 fixedly connected to the top of the base plate 1. The conveyor roller 11 allows the H-shaped steel column to be pushed on its surface, making it convenient for workers to repeatedly grind it. A fixing box 12 is fixedly connected to the top of the base plate 1 near the conveyor roller 11, and a fixing block 13 is fixedly connected to the top of the base plate 1 away from the conveyor roller 11. A limiting rod 131 is fixedly connected to the top of the fixing block 13.

[0018] In this embodiment, a grinding roller 311 is provided above the limiting rod 131, a rotating disk 34 is fixedly connected to the top of the grinding roller 311, a sealing box 32 is provided on the left side of the rotating disk 34, a push plate 321 is slidably connected to the inner wall of the sealing box 32, and an air blowing pipe 33 is fixedly connected to the left side of the sealing box 32.

[0019] Please see Figure 2 As shown, a motor 2 is fixedly connected to the front of the fixed box 12, and a bidirectional threaded rod 21 is fixedly connected to the output end of the motor 2 via a coupling.

[0020] Please see Figure 4 As shown, a fixed column 341 is fixedly connected to the top of the rotating disk 34. A movable rod 35 is in contact with the outer wall of the fixed column 341. A limit ring is provided at the top of the fixed column 341. The limit ring can restrict the movable rod 35, prevent it from falling off during rotation, and improve the stability of the device. The left side of the movable rod 35 is fixedly connected to the right side of the push plate 321. A one-way valve 322 is fixedly connected to the right side of the push plate 321.

[0021] Please see Figure 2As shown, a limiting plate 23 is fixedly connected to the inner wall of the fixed box 12. A rotating hole is provided on the front of the limiting plate 23. The opening of the rotating hole allows the bidirectional threaded rod 21 to be restricted to rotate inside it. The inner wall of the rotating hole is in contact with the middle of the outer wall of the bidirectional threaded rod 21. A moving block 211 is threadedly connected to the outer wall of the bidirectional threaded rod 21.

[0022] Please see Figure 4 As shown, a limiting groove is provided at the bottom of the moving rod 35, and the inner wall of the limiting groove contacts a limiting block.

[0023] Please see Figure 2 As shown, the top of the movable block 211 is fixedly connected with a pulley gripper 22. There are two pulley grippers 22, which are symmetrically arranged with the limiting plate 23 as the center. A connecting rod 3 is fixedly connected to the right side of the pulley gripper 22 on the back. Since the pulley gripper 22 and the grinding roller 311 are both connected through the connecting rod 3, when the two pulley grippers 22 come into contact with the H-shaped steel column, the two grinding rollers 311 can also come into contact with the H-shaped steel column and grind it.

[0024] Please see Figure 3 As shown, an assembly plate 31 is fixedly connected to the right side of the connecting rod 3. The bottom of the inner wall of the assembly plate 31 is rotatably connected to the bottom of the grinding roller 311. A rotating groove is provided on the top of the assembly plate 31, and the inner wall of the rotating groove is rotatably connected to the top of the outer wall of the grinding roller 311.

[0025] The implementation principle of the welding slag cleaning device for H-shaped steel columns in this application embodiment is as follows: The H-shaped steel column is placed on the conveying roller 11, and then the bidirectional threaded rod 21 is rotated counterclockwise by the start of the motor 2. The counterclockwise rotation of the bidirectional threaded rod 21 will drive the two moving blocks 211 to move synchronously in opposite directions until the two pulley jaws 22 are in contact with the surface of the H-shaped steel column and clamp it, so that the H-shaped steel column can move under restricted conditions. This device can not only restrict H-shaped steel columns of different widths, but also avoid the H-shaped steel column from shifting or misaligning during the grinding process, which would affect the grinding effect. The start of the two grinding rollers 311 will cause them to clean the welding slag on the H-shaped steel column. During grinding, the grinding roller 311 rotates, which in turn drives the moving rod 35 to reciprocate left and right through the rotating disk 34 and the fixed column 341. When the moving rod 35 pushes the push plate 321 to the left, the one-way valve 322 is closed. At this time, the push plate 321 pushes the air in the push plate 321 to the grinding area of ​​the weld point through the air blowing pipe 33. When the moving rod 35 drives the push plate 321 to the right, the one-way valve 322 is open, and external air is drawn into the sealing box 32, so that the device can grind the welding slag on the surface of the H-shaped steel column. At the same time, the air pushed out by the reciprocating push plate 321 during grinding can clean the welding slag that falls on its surface, so as to avoid the welding slag affecting the subsequent anti-corrosion coating process of the H-shaped steel column.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
