Description

Technical Field

[0001] This utility model relates to the field of steel rust removal technology, and in particular to a steel rust removal and grinding device. Background Technology

[0002] Steel is an iron-carbon alloy with iron as the main element and a carbon content generally below 2%, and contains other alloying elements. It is made into various engineering structures and mechanical parts through various processes. Steel is prone to rust when exposed for a long time. Rust not only affects the appearance, but also weakens its strength and durability. Therefore, rust removal is crucial. Mechanical rust removal methods are often used in the process of steel rust removal. Rust is removed by physical friction through the use of rust removal and grinding devices.

[0003] Existing rust removal and grinding devices mostly use tools such as grinding wheels and wire brushes. While these devices can remove rust from steel, the relatively smooth surfaces of the grinding wheels and wire brushes limit their effectiveness. They are only suitable for removing rust from flat steel or square steel. When processing round or oval steel, which have a certain degree of roughness, these devices cannot effectively remove rust because the grinding head cannot fully adhere to the steel surface. Some manufacturers use sandblasting machines to remove rust from round and oval steel. While sandblasting machines solve the problem of insufficient contact between the grinding head and the steel surface, they consume a large amount of silica sand and require skilled personnel to operate, resulting in high labor and material costs.

[0004] Therefore, there is an urgent need to provide a steel rust removal and grinding device to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel rust removal and grinding device.

[0006] To solve the above-mentioned technical problems, the present invention provides a steel rust removal and grinding device, including a housing mechanism and a grinding mechanism. A conveying mechanism is fixedly installed at one end of the housing mechanism, a traction mechanism is fixedly installed at the other end of the housing mechanism, and an adjustment mechanism is also fixedly installed on the housing mechanism.

[0007] A grinding mechanism is fixed at the end of the adjustment mechanism;

[0008] A tensioning mechanism is welded and fixed to the grinding mechanism to prevent the sanding belt from loosening.

[0009] The present invention is further configured such that: the housing mechanism includes a housing body, the housing body has multiple mounting holes, a support foot is welded and fixed to the bottom end of the housing body, and a reinforcing cross brace is welded and fixed to the inner side of the support foot.

[0010] Through the above technical solution, the shell body is made of stainless steel, which has high strength and corrosion resistance. The support feet can lift the shell body to a suitable height for easy operation. The reinforcing cross brace strengthens the structural strength of the device, and the mounting holes can be used to install various components.

[0011] The present invention is further configured such that: the conveying mechanism includes a mounting platform welded and fixed to one end of the housing body, a first conveying roller group is mounted on the mounting platform, a second conveying roller group is also mounted on the mounting platform, and the steel body is clamped on the inner side of the first conveying roller group and the second conveying roller group.

[0012] Through the above technical solution, the mounting platform raises the first and second conveyor roller groups to a height that matches the housing body. Both the first and second conveyor roller groups are composed of electric conveyor rollers. The first and second conveyor roller groups clamp the steel body from both sides and from the top and bottom, respectively, which can transport the steel body relatively stably.

[0013] The present invention is further configured such that the traction mechanism and the conveying mechanism have the same structure, and the traction rate of the traction mechanism is the same as the conveying rate of the conveying mechanism.

[0014] Through the above technical solution, the traction mechanism can pull the steel body from the other end of the shell body, which further improves the stability of steel conveying. After the steel body has completely passed through the conveying mechanism, the traction mechanism can continue to pull the steel body, preventing the steel body from staying inside the shell body.

[0015] The present invention is further configured such that: the adjusting mechanism includes a hydraulic cylinder installed outside the housing body, the output end of the hydraulic cylinder is fixed with a connecting plate, and two limiting posts are welded and fixed on the connecting plate.

[0016] Through the above technical solution, at least four adjustment mechanisms are provided. The four adjustment mechanisms are respectively installed on the two outer walls and the upper and lower ends of the housing body, and their installation positions are staggered. When the hydraulic cylinder extends, the distance between the two grinding mechanisms in opposite directions will shorten, and vice versa, the distance will increase. This allows the device to be applicable to steel of different specifications. The limiting column can not only make the running direction of the hydraulic cylinder more stable, but also reduce the radial pressure on the hydraulic cylinder.

[0017] The present invention is further configured such that: the grinding mechanism includes a Y-shaped mounting bracket fixed to the connecting plate, the Y-shaped mounting bracket is provided with a sliding groove, an electric roller is rotatably connected to the Y-shaped mounting bracket, a driven roller is rotatably connected to the Y-shaped mounting bracket, and a grinding belt is wound around the outside of the electric roller and the driven roller.

[0018] With the above technical solution, when the electric roller is started, the electric roller and the driven roller can drive the grinding belt to rotate, thereby grinding the steel body. The grinding mechanism is provided with at least four grinding belts, which are respectively attached to the outer wall and the upper and lower ends of the steel body. The structure of the Y-shaped mounting frame allows the grinding belt to fit more closely to the outer wall of steel bodies of different specifications and shapes, thereby improving the grinding effect and also improving the applicability of the device.

[0019] The present invention is further configured such that: the tensioning mechanism includes a fixed plate integrally fixed on a Y-shaped mounting bracket, a tensioning spring is fixed on the fixed plate, a roller frame is connected to the end of the tensioning spring, a slider is integrally fixed on the roller frame, and a tensioning roller is rotatably mounted on the roller frame.

[0020] With the above technical solution, the tension roller is in close contact with the inner side of the sanding belt. When the sanding belt is running, the tension spring can pull the tension roller, thereby providing tension to the sanding belt and preventing it from loosening. This ensures that the sanding belt can always be in full contact with the steel body. The roller frame is slidably connected to the slide groove through the slider. The slider and the slide groove can limit the position of the roller frame, thereby improving the stability of the roller frame and the tension roller.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. By setting up an adjustment mechanism and a grinding mechanism, this utility model enables the grinding part of the device to fully contact the outer wall of steel with different specifications, shapes, and sizes, thereby effectively improving the grinding effect and applicability of the device;

[0023] 2. This utility model effectively improves the stability of steel conveying by setting up a conveying mechanism and a traction mechanism, and effectively avoids the loosening of the grinding belt by setting up a tensioning mechanism, thereby improving the stability of grinding and effectively reducing the frequency of personnel maintenance.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] Please see Figures 1-5 A steel rust removal and grinding device includes a housing mechanism 1 and a grinding mechanism 5. The housing mechanism 1 includes a housing body 101 with multiple mounting holes 102. A support foot 103 is welded to the bottom of the housing body 101, and a reinforcing cross brace 104 is welded to the inner side of the support foot 103. The housing body 101 is made of stainless steel, which has high strength and corrosion resistance. The support foot 103 can raise the housing body 101 to a suitable height for easy operation. The reinforcing cross brace 104 strengthens the structural strength of the device. The mounting holes 102 can be used to install various components.

[0032] like Figure 1 and Figure 3As shown, a conveying mechanism 2 is fixedly installed at one end of the housing mechanism 1. The conveying mechanism 2 includes a mounting platform 201 welded and fixed to one end of the housing body 101. A first conveying roller group 202 is installed on the mounting platform 201, and a second conveying roller group 203 is also installed on the mounting platform 201. The inner sides of the first conveying roller group 202 and the second conveying roller group 203 hold the steel body 204. The mounting platform 201 raises the first conveying roller group 202 and the second conveying roller group 203 to a height matching that of the housing body 101. Both the first conveying roller group 202 and the second conveying roller group 203 are composed of electric conveying rollers. 03 clamps the steel body 204 from both sides and top and bottom, which can transport the steel body 204 relatively stably. The other end of the housing mechanism 1 is fixedly provided with a traction mechanism 3. The traction mechanism 3 has the same structure as the conveying mechanism 2, and the traction rate of the traction mechanism 3 is the same as the conveying rate of the conveying mechanism 2. The traction mechanism 3 can pull the steel body 204 from the other end of the housing body 101, which further improves the stability of steel transport. After the steel body 204 has completely passed through the conveying mechanism 2, the traction mechanism 3 can continue to pull the steel body 204, preventing the steel body 204 from staying inside the housing body 101.

[0033] like Figure 1 and Figure 4As shown, an adjustment mechanism 4 is also fixedly installed on the housing mechanism 1. The adjustment mechanism 4 includes a hydraulic cylinder 401 installed outside the housing body 101. A connecting plate 402 is fixed to the output end of the hydraulic cylinder 401. Two limiting posts 403 are welded and fixed on the connecting plate 402. At least four adjustment mechanisms 4 are provided. The four adjustment mechanisms 4 are respectively installed on the two outer walls and the upper and lower ends of the housing body 101, and their installation positions are staggered. When the hydraulic cylinder 401 extends, the distance between the two grinding mechanisms 5 in opposite directions will shorten, and vice versa. This allows the device to be applicable to steel of different specifications. The limiting posts 403 not only make the running direction of the hydraulic cylinder 401 more stable, but also reduce the radial pressure on the hydraulic cylinder 401. A grinding mechanism 5 is fixed to the end of the adjustment mechanism 4. The grinding mechanism 5 includes a fixed... A Y-shaped mounting bracket 501 is fixed on the connecting plate 402. The Y-shaped mounting bracket 501 has a sliding groove 502. An electric roller 503 and a driven roller 504 are rotatably connected to the Y-shaped mounting bracket 501. A grinding belt 505 is wound around the outside of the electric roller 503 and the driven roller 504. When the electric roller 503 is started, the electric roller 503 and the driven roller 504 can drive the grinding belt 505 to rotate, thereby grinding the steel body 204. At least four grinding mechanisms 5 are provided. The grinding belts 505 are respectively attached to the outer wall and the upper and lower ends of the steel body 204. The structure of the Y-shaped mounting bracket 501 allows the grinding belt 505 to fit more closely to the outer wall of steel bodies 204 of different specifications and shapes, thereby improving the grinding effect and the applicability of the device.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, a tensioning mechanism 6 for preventing the sanding belt from loosening is welded and fixed to the grinding mechanism 5. The tensioning mechanism 6 includes a fixing plate 601 integrally fixed to the Y-shaped mounting bracket 501, a tension spring 602 fixed on the fixing plate 601, a roller frame 603 connected to the end of the tension spring 602, a slider 604 integrally fixed on the roller frame 603, and a tension roller 605 rotatably mounted on the roller frame 603. The tension roller 605 is in contact with the inner side of the sanding belt 505. When the abrasive belt 505 is running, the tension spring 602 can pull the tension roller 605, thereby providing tension to the abrasive belt 505 and preventing the abrasive belt 505 from loosening. This ensures that the abrasive belt 505 can always be in full contact with the steel body 204. The roller frame 603 is slidably connected to the slide groove 502 through the slider 604. The slider 604 and the slide groove 502 can limit the position of the roller frame 603, thereby improving the stability of the roller frame 603 and the tension roller 605.

[0035] In use, the operator first operates the adjustment mechanism 4 to increase the spacing of the grinding mechanisms 5. Then, the operator can pass the steel body 204 through the conveying mechanism 2, and then turn on the grinding mechanism 5. The operator also operates the adjustment mechanism 4 to make the grinding sand belts 505 of each grinding mechanism 5 fit against the outer wall of the steel body 204. At this time, the grinding sand belts 505 will grind the steel body 204. During the grinding process, the conveying mechanism 2 will slowly convey the steel body 204. When the end of the steel body 204 contacts the traction mechanism 3, the traction mechanism 3 will also pull the steel body 204 at the same time. When the steel body 204 has completely passed through the device, the grinding of the steel body 204 is completed.
