Description

Technical Field

[0001] The utility model relates to the technical field of steel structure grinding, in particular to a rust removal device for the surface of a steel structure. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. After a steel structure device is used for a period of time, it may need to be disassembled. Due to being exposed to the external environment for a long time after disassembly, the steel structure will rust. In order to enable it to be used continuously in the later stage, rust removal operations need to be carried out. Generally, grinding is mainly used for rust removal operations on steel structures.

[0003] In view of this, Chinese Patent No. CN213164735U proposes a rust removal device for the surface of a steel structure. The purpose of the utility model is to provide a rust removal device that is flexible to use and can well remove rust from the edges and corners of sections, especially steel structures;

[0004] However, in the process of grinding and rust removal with the above technical solution and the existing steel structure rust removal devices, during grinding, since the grinding equipment rotates at a high speed and repeatedly grinds the surface of the steel structure, there may be some unground spot areas, or the debris generated by grinding will remain on the surface of the steel structure. If not processed in time, when the grinding equipment repeatedly grinds, it will squeeze with the debris, resulting in more depressions and scratches in the grinding area of the steel structure, and in severe cases, it may cause damage to the grinding equipment. When manually cleaning by workers, the grinding equipment needs to be paused, reducing the rust removal efficiency and increasing the operation burden of the workers. In view of this, a rust removal device for the surface of a steel structure is proposed in this design solution. Content of the Utility Model

[0005] In order to solve the above problems, the purpose of the utility model is to provide a rust removal device for the surface of a steel structure to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model proposes a rust removal device for the surface of a steel structure, including a processing table, and a grinding mechanism and a fixing mechanism that are both installed on the processing table and are distributed up and down;

[0007] The grinding mechanism includes a first chute opened at the upper edge of one side of the inner wall of the processing table. A moving bracket is slidably provided on the inner wall of the first chute. A connecting frame is rotatably provided at the lower edge of one side of the moving bracket. A grinding wheel is rotatably provided at one end of the connecting frame. A scraping blade is fixedly provided at the edge of one side of the bottom of the connecting frame.

One end of the grinding wheel passes through the outer wall of the connecting frame and is connected to a first motor, and one end of the gear passes through the inner wall of one side of the moving bracket and is connected to a second motor.

[0008] In one example, a support frame is fixedly provided at the edge of one end of the bottom of the moving bracket. A moving wheel is rotatably provided at the bottom of the support frame. A limiting groove is opened at the edge of one side of the top of the processing table, and the outer wall of the moving wheel is in rolling connection with the inner wall of the limiting groove.

[0009] In one example, a one-way lead screw is rotatably provided on the inner wall of the first chute, and the outer wall of the one-way lead screw is in threaded connection with the inner wall of one end of the moving bracket. One end of the one-way lead screw passes through the outer wall of the processing table and is connected to a third motor.

[0010] In one example, the fixing mechanism includes second chutes opened at both ends of both sides of the top of the processing table. Connecting grooves are opened at the middle positions of both ends of the top of the processing table. A bidirectional lead screw is inserted through the inner walls of the two connecting grooves.

[0014] The steel structure surface rust removal device proposed by the present utility model can bring the following beneficial effects:

[0015] For this steel structure surface rust removal device, after fixing the steel structure parts, start the third motor to make the one-way lead screw drive the moving bracket to move back and forth, and make the grinding wheel contact the surface of the steel structure parts obliquely downward for grinding.

[0024] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0025] The embodiments are as follows. The present utility model provides a steel structure surface rust removal device as shown in Figures 1-5 Figure 5, which includes a processing table 1, and a grinding mechanism 2 and a fixing mechanism 3 that are both installed on the processing table 1 and are distributed up and down.

[0026] The grinding mechanism 2 includes a first chute 201 opened at the upper edge of one side of the inner wall of the processing table 1. A moving bracket 202 is slidably provided on the inner wall of the first chute 201. A connecting frame 203 is rotatably provided at the lower edge of one side of the moving bracket 202. A grinding wheel 204 is rotatably provided at one end of the connecting frame 203. A scraping blade 205 is fixedly provided at the edge of one side of the bottom of the connecting frame 203. An arc-shaped toothed ring 206 is fixedly provided at the middle position of the top of the connecting frame 203. A gear 207 is rotatably provided above the connecting frame 203 on one side of the moving bracket 202. The outer wall of the gear 207 meshes with the outer wall of the arc-shaped toothed ring 206. One end of the grinding wheel 204 passes through the outer wall of the connecting frame 203 and is connected to a first motor 208. One end of the gear 207 passes through the inner wall of one side of the moving bracket 202 and is connected to a second motor 209. By meshing the gear 207 with the arc-shaped toothed ring 206, the inclination of both ends of the connecting frame 203 is adjusted, so that the grinding wheel 204 and the scraping blade 205 contact the rigid connection. At the same time, when the scraping blade 205 contacts the surface of the steel structure part, it can be smoothly slid on the surface of the steel structure part and scrape off debris driven by the moving bracket 202. At the same time, when the gear 207 meshes with the arc-shaped toothed ring 206, the connecting frame 203 being ground can be firmly fixed to keep it stable.

[0027] Further, a support frame 210 is fixedly provided at the edge of one end of the bottom of the moving bracket 202. A moving wheel 211 is rotatably provided at the bottom of the support frame 210. A limiting groove 212 is opened at the edge of one side of the top of the processing table 1. The outer wall of the moving wheel 211 is in rolling connection with the inner wall of the limiting groove 212. When the moving bracket 202 slides in the first chute 201, it is supported in the limiting groove 212 through the support frame 210 and the moving wheel 211, and the moving wheel 211 rolls in the limiting groove 212, making its movement smoother and also playing a supporting role.

[0028] A one-way lead screw 213 is rotatably provided on the inner wall of the first sliding groove 201, and the outer wall of the one-way lead screw 213 is threadedly connected to the inner wall of one end of the moving bracket 202. One end of the one-way lead screw 213 passes through the outer wall of the processing table 1 and is connected to a third motor 214;

[0029] Further, the fixing mechanism 3 includes second sliding grooves 301 opened at both ends of the two sides of the top of the processing table 1. Connecting grooves 302 are opened at the middle positions of both ends of the top of the processing table 1. A bidirectional lead screw 303 is inserted through the inner walls of the two connecting grooves 302. The two second sliding grooves 301 mainly play a role in limiting the movement of the adjusting base 305 and making its movement more stable;

[0030] Further, one end of the bidirectional lead screw 303 passes through the outer wall of the processing table 1 and is connected to a rotating handle 304. Adjusting bases 305 are installed on both sides of the top of the processing table 1, and the outer walls of the two adjusting bases 305 are respectively slidably connected to the inner walls of the four second sliding grooves 301 and the inner walls of the two connecting grooves 302.

[0031] The outer walls of both ends of the bidirectional lead screw 303 are respectively threadedly connected to the inner walls of one side of the two adjusting bases 305. A limiting clamp 306 is fixedly provided on one side of each of the two adjusting bases 305. A protective pad 307 is fixedly provided on one side of each of the two limiting clamps 306. Support blocks 308 are fixedly provided at the lower edges of one side of each of the two limiting clamps 306. When the two ends of the steel structure member are squeezed and fixed by the limiting clamps 306, they are supported by the support blocks 308 at the bottom of the steel structure, so that it is not easy to fall off during grinding. At the same time, a protective pad 307 is provided on one side of the limiting clamp 306 to play a role in protecting and preventing wear of the steel structure member.

[0032] Working principle: When using the steel structure surface rust removal device in this design solution, first place the steel structure part on the top of the processing table 1. By rotating the rotating handle 304 at one end, the bidirectional lead screw 303 drives the adjusting bases 305 at both ends to slide in the two connecting grooves 302, thereby squeezing both ends of the steel structure part and supporting it with the support block 308 at the bottom. Then, start the first motor 208 to rotate the grinding wheel 204 and start the second motor 209 to drive the gear 207 to engage with the arc-shaped toothed ring 206, so that one end of the connecting frame 203 where the grinding wheel 204 is located inclines downward and contacts the surface of the steel structure part below for grinding. Start the third motor 214, and driven by the unidirectional lead screw 213, the moving bracket 202 drives the grinding mechanism 2 to move back and forth on the surface of the steel structure part for grinding and rust removal. When grinding once, reverse-drive the second motor 209 to make the scraping blade 205 at the other end of the connecting frame 203 face downward and move to scrape the surface of the steel structure part after grinding clean, so that the debris and spots that have not been ground off are scraped off. When grinding again, the extrusion between the debris and spots and the grinding wheel 204 is reduced, the damage to the grinding wheel 204 is reduced, and at the same time, the scratches on the steel structure surface are also reduced, improving the protection performance of the device.
