Description

Technical Field

[0001] This utility model relates to the field of steel structure production technology, specifically to a slag removal device that can remove welding slag from dead corners of steel structures. Background Technology

[0002] After welding, steel structures undergo painting to extend their service life. However, before painting, the steel structure usually needs to be descaled and derusted to prevent it from decaying from within the primer after painting.

[0003] During the welding process of steel structures, weld slag may splash onto the surface of the steel structure, cool and solidify, and firmly bond to the surface. Although sandblasting and shot blasting equipment can use foreign objects to impact the surface of the steel structure at high speed during the rust removal process to remove impurities and rust, the impurities and rust are not firmly bonded to the surface of the steel structure. After the foreign object impacts the surface of the steel structure, the surface vibrates at high frequency. Although it can complete the surface rust removal and impurity removal treatment, it cannot remove the weld slag that is firmly attached to the structure.

[0004] Therefore, before rust removal from steel structures, slag removal treatment is necessary on the surface. Although weld slag doesn't follow a fixed pattern when it spatters, it tends to land close to the welding point. Since steel structures are typically welded from two or more steel plates, there's often an angle between the plates after welding. This results in a significant portion of the weld slag settling near the corners and dead angles of the steel structure after cooling. Currently, the common method for handling weld slag is to manually observe its location and then remove it using tools like shovels. This method is inefficient and ineffective at removing slag near the corners and dead angles of the steel structure.

[0005] Based on this, the inventors designed a slag removal device that can remove welding slag from dead corners of steel structures, which can solve the problems of low efficiency of manual slag removal and inability to remove welding slag from dead corners of steel structures. Therefore, this application is filed. Summary of the Invention

[0006] The purpose of this application is to provide a handheld steel structure welding slag removal device to solve the problems of low efficiency of manual slag removal and inability to remove welding slag in dead corners of steel structures.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following solution:

[0008] This application provides a slag removal device for removing slag from dead corners of steel structures, including a gripping part and a slag removal mechanism fixed to the gripping part:

[0018] Optionally, the elastic guide assembly includes an L-shaped mounting block mounted on the motor mounting housing, a guide rod fixed to the L-shaped mounting block, and a spring fitted on the guide rod, wherein a limit protrusion is provided at the end of the guide rod away from the L-shaped mounting block;

[0019] The guide rod passes through the square limiting cover and is slidably connected to it, and the spring is located between the square limiting cover and the L-shaped mounting block.

[0020] Optionally, a square elastic pad is also provided at the bottom of the square limiting cover.

[0021] Optionally, it also includes a power supply unit for electrical connection with the drive motor; and a pressure sensor for controlling the circuit connection between the drive motor and the power supply unit, the pressure sensor being disposed between the grip and the slag removal mechanism.

[0027] The beneficial effects of this utility model are:

[0036] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0037] like Figure 1 and Figure 2 As shown, this embodiment provides a slag removal device for removing weld slag from dead corners of steel structures, including a gripping part and a slag removal mechanism fixed to the gripping part:

[0038] The slag removal mechanism includes a drive motor 2, a floating transmission assembly 4, and a slag removal impeller 3 with a Reuleaux triangle cross-sectional shape, wherein:

[0039] One end of the floating transmission component 4 is fixedly connected to the output shaft of the drive motor 2, and the other end is fixedly connected to the slag removal impeller 3. A slag removal structure 31 is provided on the side of the slag removal impeller 3 away from the drive motor 2.

[0040] It also includes a square limiting cover 5 that is fixedly connected to the drive motor 2, and the edge of the slag removal impeller 3 is in active contact with the square limiting cover 5.

[0041] This embodiment features a gripping part and a slag removal mechanism fixed to the gripping part. The slag removal mechanism includes a square limiting cover 5 and a Reuleaux triangular slag removal impeller 3 driven to rotate by a drive motor 2. The slag removal impeller 3 is in active contact with the inner wall of the square limiting cover 5, allowing the slag removal area to be the positive direction area within the square limiting cover 5. This enables the application not only to remove slag from the surface of the steel structure but also to approach and abut against the dead corner area of ​​the steel structure to remove slag from the dead corner area. This effectively solves the problem of low efficiency and inability to remove slag from dead corners of steel structures by manual slag removal.

[0042] In this embodiment, the Reuleaux triangle, combined with a square frame, can cover the entire square during rotation, which is a prior art technique. Its conventional application is to use its principle to drill square holes. The core concept of this application is to utilize the special property that the Reuleaux triangle covers a square area during rotation, allowing it to penetrate into the dead corners of the steel structure, thereby removing slag from the dead corners of the steel structure.

[0043] In an optional embodiment, the slag removal structure 31 of the slag removal impeller 3 is any one of outwardly protruding convex points, radial edges, or a mesh structure. In this embodiment, for example... Figure 2 As shown, the slag removal structure 31 of the slag removal impeller 3 is a mesh structure. During the rotation of the slag removal impeller 3, the mesh structure will remove the welding slag protruding from the surface of the steel structure. Technicians can also choose other shapes such as protrusions, radially protruding edges, etc., which will not be elaborated here.

[0044] Specifically, in this embodiment, such as Figure 1 As shown, the floating transmission component 4 is a universal joint, and the slag removal impeller 3 is provided with a mounting hole 32. The universal joint is fixedly connected to the slag removal impeller 3 through the mounting hole 32.

[0045] In this embodiment, such as Figure 1 As shown, the slag removal mechanism also includes a motor mounting housing, and the drive motor 2 is mounted on the motor mounting housing;

[0046] The square limiting cover 5 is connected to the motor mounting housing. The square limiting cover 5 can also prevent welding slag from flying out during the removal process and causing injury to the workers.

[0047] Specifically, in this embodiment, such as Figure 1 As shown, the slag removal mechanism also includes several elastic guide components 6 distributed circumferentially along the motor mounting housing, and the guiding direction of the elastic guide components 6 is parallel to the output shaft of the drive motor 2.

[0048] The square limiting cover 5 is connected to the motor mounting housing via an elastic guide assembly 6. The elastic guide assembly 6 allows the square limiting cover 5 to move along its guiding direction, ensuring that the entire slag removal impeller 3 is covered within the square limiting cover 5 before startup, preventing the impeller 3 from being exposed.

[0049] In this embodiment, as Figure 1 As shown, the elastic guide assembly 6 includes an L-shaped mounting block 62 mounted on the motor mounting housing, a guide rod 61 fixed on the L-shaped mounting block 62, and a spring 63 fitted on the guide rod 61, and a limit protrusion is provided at the end of the guide rod 61 away from the L-shaped mounting block 62;

[0050] The guide rod 61 passes through the square limiting cover 5 and is slidably connected to it, and the spring 63 is located between the square limiting cover 5 and the L-shaped mounting block 62.

[0051] In this embodiment, a square elastic pad is also provided at the bottom of the square limiting cover 5.

[0052] Specifically, in this embodiment, it also includes a power supply body for electrical connection with the drive motor 2; and a pressure sensor for controlling the circuit connection between the drive motor 2 and the power supply body, the pressure sensor being disposed between the gripping part and the slag removal mechanism;

[0053] It also includes a start button 8 located on the grip, and the drive motor 2 is electrically connected to the power supply unit via the start button 8. The start button 8 and pressure sensor are provided so that the entire circuit is only connected after the operator presses the slag removal impeller 3 to contact the surface of the steel structure, and then the start button 8 is turned on to start slag removal. This avoids the safety hazard caused by the square limit cover 5 of the device being opened even when it is not pressed against the surface of the object.

[0054] Specifically, in this embodiment, the gripping part includes a gripping body 11 and a detachable power mounting bracket 7 disposed within the gripping body 11;

[0055] The gripping body 11 is arranged vertically or parallel to the axial direction of the output shaft of the drive motor 2;

[0056] It also includes a main grip position 12 and an auxiliary grip position 13 disposed on the grip body 11. The dual grip positions can improve stability during use. In this embodiment, for example... Figure 1 As shown, the gripping body 11 is axially perpendicular to the output shaft of the drive motor 2. Technicians can also choose to axially position the gripping body 11 parallel to the output shaft of the drive motor 2.

[0057] Specifically, in this embodiment, the gripping body 11 has a hollow structure; a plurality of elastic retaining rings 71 are fixedly mounted on the power mounting bracket 7, and the power mounting bracket 7 is detachably inserted into the gripping body 11 through the elastic retaining rings 71, which facilitates the assembly and disassembly of the power mounting bracket 7 and makes device maintenance convenient.

[0058] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of this utility model, and the utility model is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of this utility model, and these modifications and improvements are also considered to be within the protection scope of this utility model.
