Description

Technical Field

[0001] The utility model relates to the technical field of rust removal devices, and more particularly to a rust removal device for the surface of steel structures. Background Technique

[0002] In the field of steel structure construction and maintenance, especially in the preparatory stage before anti-corrosion construction of steel structures, it is crucial to conduct a comprehensive rust removal treatment on the surface of steel structures. The thoroughness of rust removal directly affects the adhesion of the subsequent anti-corrosion coating and the service life of the entire steel structure. However, in actual construction, especially when dealing with materials of complex shapes such as steel structures, H-beams, and I-beams, some challenges are often faced.

[0003] Traditional rust removal methods, such as using manual sandpaper, grinding wheels, or angle grinders, have significant limitations when dealing with hard-to-reach areas such as internal corners, dead corners, punched and perforated positions, and areas around bolts on the surface of steel structures. These tools often cannot effectively enter and thoroughly remove the rust in these areas due to size limitations or inconvenient operation, resulting in poor rust removal effects, which in turn affects the quality of the entire anti-corrosion system. In addition, although the traditional angle grinder has improved the rust removal efficiency to a certain extent, its processing ability for fine parts and complex shapes is still limited, and the dust and noise generated during the operation also pose a certain threat to the health of workers. Another more advanced laser rust removal technology, although it has remarkable rust removal effects, its high cost and complex equipment requirements have greatly limited its application in actual construction. Therefore, in view of the above technical problems, a rust removal device for the surface of steel structures is proposed here. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rust removal device for the surface of steel structures, which can arbitrarily adjust the corresponding angle of the first scraper, facilitating the insertion of the first scraper into areas that are difficult for human hands to reach, and cooperating with the second scraper adapted to various grooves for rust removal, which can not only improve the rust removal efficiency, but also expand the rust removal area, being relatively convenient.

[0005] The utility model is realized through the following technical solutions:

[0006] A rust removal device for the surface of steel structures includes a motor box, on one side of which an angle adjustment mechanism is installed. A driving motor is fixedly connected inside the motor box. One side of the driving motor is fixedly connected with a rotating shaft, the end of the rotating shaft is fixedly connected with a connecting block, the end of the connecting block is fixedly connected with a first scraper, telescopic components are detachably connected to both sides of the connecting block, and a second scraper is fixedly connected to the outside of the telescopic components.

[0007] Preferably, the angle adjustment mechanism includes a connecting rod, a rotating rod and a limiting plate. The connecting rod is fixedly connected to the outside of the motor box. The rotating rod is rotatably connected to the outside of the connecting rod. The limiting plate is fixedly connected to the outside of the rotating rod, and the limiting plate is located on both sides of the connecting rod.

[0008] Preferably, grips are fixedly connected to both sides of the rotating rod.

[0009] Preferably, the rotating shaft is rotatably connected to the motor box.

[0010] Preferably, the telescopic assembly includes a mounting base, a sliding plate, a telescopic rod, a spring and a fixing rod. The sliding plate is slidably connected to the inside of the mounting base. The telescopic rod and the spring are both fixedly connected between the sliding plate and the mounting base, and the spring is located on both sides of the telescopic rod.

[0011] Preferably, the fixing rod is fixedly connected to the other side of the sliding plate, and the fixing rod is slidably connected to the mounting base. The second scraper is fixedly connected to the end of the fixing rod, and both the upper and lower sides of the second scraper are processed into inclined surfaces.

[0012] Preferably, a connecting plate is fixedly connected to the outside of the mounting base, and the connecting plate is threadedly connected to the outside of the connecting block through bolts.

[0013] The technical solution of the present utility model has at least the following beneficial effects:

[0014] A steel structure surface rust removal device proposed by the present utility model rotates the connecting rod around the rotating rod, thereby controlling the motor box to rotate around the rotating rod, and then adjusting the corresponding angle of the first scraper, so that the first scraper can be extended into an area that is not easily accessible by hand for rust removal. When the first scraper extends into the groove body, due to the inclined surface treatment on the outside of the second scraper, under the action of force, the second scraper will be driven to push the fixing rod inward, so that the second scraper can be inserted into the groove body. After being inserted into the groove body, under the action of the spring, the second scraper can automatically reset and abut against the inside of the groove body, and then rust removal inside the groove body is carried out. In this way, by cooperating with the second scraper adapted to various groove bodies for rust removal, not only can the rust removal efficiency be accelerated, but also the rust removal area can be expanded, which is relatively convenient.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0022] Please refer to Figures 1-5 , a steel structure surface rust removal device proposed by the present utility model, including a motor box 1, an angle adjustment mechanism is installed on one side of the motor box 1, a driving motor 6 is fixedly connected inside the motor box 1, a rotating shaft 7 is fixedly connected to one side of the driving motor 6, a connecting block 8 is fixedly connected to the end of the rotating shaft 7, a first scraper 9 is fixedly connected to the end of the connecting block 8, telescopic components are detachably connected to both sides of the connecting block 8, and a second scraper 16 is fixedly connected to the outside of the telescopic components.

[0023] The angle adjustment mechanism includes a connecting rod 2, a rotating rod 3 and a limiting plate 4. The connecting rod 2 is fixedly connected to the outside of the motor box 1, the rotating rod 3 is rotatably connected to the outside of the connecting rod 2, the limiting plate 4 is fixedly connected to the outside of the rotating rod 3, and the limiting plate 4 is located on both sides of the connecting rod 2.

[0024] Grips 5 are fixedly connected to both sides of the rotating rod 3. Through the grips 5, it is convenient for the staff to better control this device for rust removal. The rotating shaft 7 is rotatably connected to the motor box 1.

[0025] The telescopic component includes a mounting seat 10, a slide plate 12, a telescopic rod 13, a spring 14 and a fixed rod 15. The slide plate 12 is slidably connected to the inside of the mounting seat 10. The telescopic rod 13 and the spring 14 are both fixedly connected between the slide plate 12 and the mounting seat 10, and the spring 14 is located on both sides of the telescopic rod 13.

[0026] The fixed rod 15 is fixedly connected to the other side of the sliding plate 12, and the fixed rod 15 is slidably connected to the mounting seat 10. The second scraper 16 is fixedly connected to the end of the fixed rod 15, and both the upper and lower sides of the second scraper 16 are processed into inclined surfaces. Both the first scraper 9 and the second scraper 16 are made of stainless steel material.

[0027] A connecting plate 11 is fixedly connected to the outside of the mounting seat 10, and the connecting plate 11 is threadedly connected to the outside of the connecting block 8 through bolts. Through the threaded connection of the bolts, the detachable connection between the mounting seat 10 and the connecting block 8 can be realized.

[0028] Based on the working principle of a steel structure surface rust removal device in the embodiment, when this device is in use, the staff for rust removal of the steel structure can hold the grip 5 and rotate the connecting rod 2 around the rotating rod 3, thereby controlling the motor box 1 to rotate around the rotating rod 3, and then adjusting the corresponding angle of the first scraper 9, so that the first scraper 9 can be extended into the area that is not easily reachable by hand. Then, by operating the driving motor 6, the rotating shaft 7 drives the connecting block 8 to rotate, so that the first scraper 9 can rotate at a high speed to remove rust from this area. And if it is necessary to remove rust from the inside of a steel structure with a groove, and the opening of the groove is relatively narrow and the internal space is relatively large, the mounting seat 10 can be installed on both sides of the connecting block 8 through the connecting plate 11. When the first scraper 9 extends into the groove, because the outside of the second scraper 16 is processed into an inclined surface, when the groove opening of this structure contacts and presses the second scraper 16, under the action of force, it will drive the second scraper 16 to push the fixed rod 15 inward, thereby driving the sliding plate 12 to compress the spring 14, and the second scraper 16 can be inserted into the groove. After being inserted into the groove, under the action of the spring 14, the second scraper 16 can automatically reset and abut against the inside of the groove, and then operate the driving motor 6 to remove rust from the inside of the groove. In this way, by cooperating with the second scraper 16 that adapts to various grooves for rust removal, not only can the rust removal efficiency be improved, but also the rust removal area can be expanded, which is relatively convenient.
