Description

TECHNICAL FIELD

[0001] The utility model relates to steel structure production technical field, concretely relates to a handheld welding slag removing device for steel structure. BACKGROUND

[0002] After the steel structure is welded, it needs to be painted to prolong the service life of the steel structure. However, before the painting process, the steel structure usually needs to be deslagged and derusted to prevent it from decaying from the inside of the primer after painting.

[0003] During the welding process, the welding slag may splash onto the surface of the steel structure and be fixed there, firmly bonding to the surface of the steel structure. Although the sandblasting equipment and the shot blasting equipment can impact the surface of the steel structure at high speed to remove impurities and rust from the surface of the steel structure during the derusting process, the impurities and rust are not firmly bonded to the surface of the steel structure. Therefore, after the foreign objects impact the surface of the steel structure, the surface of the steel structure vibrates at high frequency, completing the derusting and impurity removal process, but the firmly structured welding slag cannot be removed.

[0004] Therefore, before the derusting process of the steel structure, the surface of the steel structure needs to be deslagged. Since the welding slag does not have a fixed pattern when it splashes, the current deslagging process for the steel structure is usually performed manually by observing the position of the welding slag and then using a shovel or other tool to remove it. Due to the lack of efficient and specialized deslagging tools, the efficiency of removing the welding slag is low, and the labor intensity is high.

[0005] Based on this, the inventor designed a handheld welding slag removing device for steel structure to solve the problem of the lack of efficient and specialized deslagging tools for manual deslagging, thus presenting the present application. SUMMARY

[0038] Example 1:

[0039] like Figures 1 to 3 As shown, this embodiment provides a handheld welding slag removal device for steel structures, including a gripping part 1 and a welding slag removal mechanism fixed to the gripping part 1, as well as a power supply body, wherein:

[0040] The slag removal mechanism includes a drive motor 2 fixedly connected to the gripping part 1, and a slag removal impeller 3 disposed on the output shaft of the drive motor 2. The drive motor 2 is electrically connected to the power supply body, and the side of the slag removal impeller 3 away from the drive motor 2 is on the same plane.

[0041] This embodiment uses a gripping part 1, a slag removal mechanism fixed to the gripping part 1, and a power supply body. Since the slag removal mechanism includes a drive motor 2 and a slag removal impeller 3, and the drive motor 2 is electrically connected to the power supply body, when the operator grips the gripping part 1, the side of the slag removal impeller 3 away from the drive motor 2 is on the same plane. This allows the slag removal impeller 3 to be brought close to and pressed against the steel structure surface with slag. Then, the drive motor 2 drives the slag removal impeller 3 to rotate, which allows the slag removal impeller 3 to quickly remove the slag, thus achieving rapid removal of slag from the steel structure surface and solving the problem of the lack of efficient dedicated slag removal tools in the prior art.

[0042] Specifically, in the embodiment, the slag removing impeller 3 comprises a coaxially fixed connecting shaft 32 and an impeller body 33, and a plurality of slag removing blades 31 arranged on the circumferential wall of the impeller body 33.

[0043] The connecting shaft 32 is detachably coaxially fixedly connected with the output shaft of the driving motor 2.

[0044] The slag removing blades 31 and the impeller body 33 are located in the same plane away from the driving motor 2.

[0045] In the embodiment, the impeller body 33, the slag removing blades 31 and the connecting shaft 32 are integrally formed, and the impeller body 33, the slag removing blades 31 and the connecting shaft 32 are made of high-strength alloy steel or tungsten steel or other high-strength materials to ensure durability. Meanwhile, the connecting body is detachably fixedly connected with the output shaft of the driving motor 2 through a shaft coupling, so that the slag removing impeller 3 can be conveniently replaced.

[0046] Optionally, the cross section of the slag removing blade 31 can be a right trapezoid or an isosceles trapezoid. Specifically, in the embodiment, the cross section of the slag removing impeller 3 is a right trapezoid. Other shapes can also be selected by the skilled person, which will not be described here.

[0047] Specifically, the included angle between the inclined surface and the bottom surface of the slag removing blade 31 ranges from 30° to 75°. In the embodiment, the included angle is 45°, and other angles such as 60° can also be selected, which will not be exemplified one by one here.

[0049] The slag removing mechanism further comprises an elastic guide assembly 6 installed on the motor mounting shell 4 and a shroud 5 installed on the elastic guide assembly 6. The guide direction of the elastic guide assembly 6 is parallel to the axial direction of the slag removing impeller 3, and the slag removing impeller 3 is located in the shroud 5. The motor mounting shell 4, the elastic guide assembly 6 and the shroud 5 are arranged to avoid the splashing of the removed welding slag of the slag removing impeller 3, which affects the safety of the operator.

[0051] The elastic guide assembly 6 comprises an L-shaped mounting block 62 installed on the motor mounting shell 4, a guide rod 61 fixed to the L-shaped mounting block 62, and a spring 63 sleeved on the guide rod 61. The end of the guide rod 61 away from the L-shaped mounting block 62 is provided with a limiting protrusion.

[0052] The guide rod 61 is arranged through the shield 5 and is in sliding connection with the shield 5, and the spring 63 is arranged between the shield 5 and the L-shaped mounting block 62.

[0053] Specifically, in the embodiment, the shield 5 is further provided with an elastic blocking pad 51.

[0054] Specifically, in the embodiment, a pressure sensor (not shown in the figure) for controlling the on-off of the circuit between the driving motor 2 and the power body is further included, and the pressure sensor is arranged between the holding part 1 and the slag removing mechanism.

[0055] The starting button 8 arranged on the holding part 1 is further included, and the driving motor 2 is electrically connected with the power body through the starting button 8. The starting button 8 and the pressure sensor are arranged, so that the operator needs to push the slag removing impeller 3 to contact the surface of the steel structure, and then the entire circuit is turned on, and the slag is removed by opening the starting button 8, thereby avoiding the direct opening of the entire device, which causes a safety hazard.

[0056] In some embodiments, a warning light (not shown in the figure) can be arranged, which is started according to the signal of the pressure sensor, and reminds the operator that the slag removing impeller 3 has contacted the surface of the steel structure, and prepares for slag removal, thereby facilitating the operator to identify and operate.

[0062] The main holding position 12 and the auxiliary holding position 13 are respectively arranged on the holding main body 11 and the handle 14. The difference between the embodiment and the above-mentioned embodiment 1 is that the handle 14 is arranged, and the main holding position 12 and the starting button 8 are arranged on the handle 14. Compared with embodiment 1, the embodiment actually provides a new holding mode different from embodiment 1, which is convenient for the operator to use.

[0063] The rest of the structure of the embodiment is the same as that of embodiment 1, and will not be described here.

[0064] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the utility model, and the utility model is not limited thereto.
