Description

Technical Field

[0001] This utility model relates to the field of steel structure processing, and more specifically, to a steel structure processing spraying device. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. Due to its light weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. However, steel structures are prone to corrosion. Generally, steel structures need to be derusted, galvanized or painted, and require regular maintenance.

[0003] A search revealed that Chinese patent CN220215447U discloses "a steel structure processing and spraying device, comprising: a main body, a placement plate connected to the side of the main body near the top, a positive and negative motor installed on the top of the placement plate, a threaded screw driven by the positive and negative motor near the side of the main body, a heating component located on one side of the main body for heating the interior of the main body, and a ventilation component located inside the main body for removing odors from the interior of the main body. This spraying device can heat the interior of the main body through the heating component, thereby reducing the drying time of the coating. Secondly, the purification component can remove odors from the interior of the main body, preventing odor residue from remaining inside the main body." However, the following defects still exist:

[0004] When using this device, the spraying pipe can only spray in one direction. When spraying I-shaped steel structures, the direction and position of the steel structure must be readjusted after each spraying before the other side can be sprayed, which is inconvenient and greatly reduces work efficiency. To address this, a steel structure processing and spraying device is proposed. Utility Model Content

[0005] The purpose of this utility model is to address the problem that, when spraying H-shaped steel structural components, it is necessary to readjust the direction and position of the steel structure after each spraying before spraying the other side, which is inconvenient and greatly reduces work efficiency.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] The present invention is as follows: a steel structure processing and spraying device, including a frame, a spraying mechanism for spraying paint on steel structural components is provided on one side of the frame, and a conveying component for conveying steel structural components is provided on one side of the frame.

[0008] The spraying mechanism includes a servo motor bolted to the outer wall of the frame. A first lead screw is coaxially mounted on the output end of the servo motor. A second lead screw is rotatably connected to the inner wall of the frame. A first pulley is fixedly connected to the side of both the first and second lead screws extending to the outside of the frame. A first belt is mounted on the outer wall of the first pulley. Two stabilizing rods are fixedly connected to the inner wall of the frame. Movable frames are threaded to the outer walls of both the first and second lead screws. Spraying pipes are fixedly connected to the opposite sides of the two movable frames. Two paint pumps are mounted on the side of the frame away from the servo motor. A storage tank is mounted on one side of the frame. Flexible hoses are mounted on the output ends of both paint pumps.

[0009] As a preferred technical solution of this utility model, the conveying assembly includes a reduction motor bolted to the outer wall of the frame, a first friction roller coaxially arranged at the output end of the reduction motor, a second friction roller rotatably connected inside the frame, and a second pulley fixedly connected to one side of the first and second friction rollers extending to the outside of the frame, and a second belt arranged on the outer wall of the second pulley.

[0010] As a preferred technical solution of this utility model, multiple soft curtains are provided on both opposite sides of the frame, a fan is bolted to the top of the frame, a fixed pipe is provided at the output end of the fan, a resistance wire is provided on the inner wall of the fixed pipe, and the end of the fixed pipe away from the fan extends into the interior of the frame.

[0011] As a preferred technical solution of this utility model, an extension frame is fixedly connected to the top of the frame, and an exhaust fan is provided on the inner wall of the extension frame. The extension frame is connected to the interior of the frame.

[0012] As a preferred technical solution of this utility model, a placement frame is fixedly connected to the top of the extension frame, and a filter frame is slidably connected inside the placement frame. Both the placement frame and the filter frame have multiple ventilation holes that penetrate through them.

[0013] As a preferred technical solution of this utility model, an extension column is fixedly connected to one side of the placement frame, and a baffle is hinged to the outer wall of the extension column.

[0014] As a preferred technical solution of this utility model, a sliding plate is fixedly connected to both sides of the two movable frames, and a protective frame is fixedly connected to the inner walls of the opposite sides of the frame, and the sliding plate is slidably connected to the inside of the protective frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. The spraying mechanism enables comprehensive spraying of I-shaped steel structural components. A servo motor drives the first lead screw and the first drive to rotate, which in turn drives the second lead screw via the first belt. This causes the two moving frames to move synchronously, pouring the paint to be sprayed into the storage tank and simultaneously activating two paint pumps. This allows for simultaneous spraying of paint on both the top and bottom surfaces of the steel structural components, reducing the need to flip the components and improving work efficiency.

[0017] 2. The set conveying components realize the effect of conveying the steel structure inside the frame; by starting the reduction motor, the first friction roller and the second pulley can be rotated, and then the second friction roller is rotated through the second belt. When the steel structure is inside the frame, the first friction roller and the second friction roller rotating in the same direction will contact the bottom of the steel structure and continuously convey the steel structure for spraying operation, reducing manual operation.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0026] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0028] like Figure 1 As shown, this embodiment proposes a steel structure processing and spraying device, including a frame 1, a spraying mechanism 2 for spraying paint on steel structural components is provided on one side of the frame 1, and a conveying assembly 3 for conveying steel structural components is provided on one side of the frame 1.

[0029] like Figure 2As shown, the spraying mechanism 2 includes a servo motor 201 bolted to the outer wall of the frame 1. A first lead screw 202 is coaxially mounted on the output end of the servo motor 201. A second lead screw 203 is rotatably connected to the inner wall of the frame 1. A first pulley 204 is fixedly connected to both the first lead screw 202 and the second lead screw 203 on one side extending outside the frame 1. A first belt 205 is mounted on the outer wall of the first pulley 204. The servo motor 201, the first pulley 204, and the first belt 205 can cause the first lead screw 202 and the second lead screw 203 to rotate in the same direction. Two stabilizing rods 206 are fixedly connected to the inner wall of the frame 1. The two stabilizing rods 206 are located below the first lead screw 202 and above the second lead screw 203, respectively. The wall is threaded with a movable frame 207. The two movable frames 207 slide along the length of the two stabilizer rods 206 respectively. The stabilizer rods 206 can maintain the stability of the movable frame 207 when moving. Spray pipes 208 are fixedly connected to the opposite side of the two movable frames 207. Two paint pumps 209 are provided on the side of the frame 1 away from the servo motor 201. A storage tank 210 is provided on one side of the frame 1. The input ends of the two paint pumps 209 are connected to the inside of the storage tank 210. The output ends of the two paint pumps 209 are provided with hoses 211. The two hoses 211 are connected to the two spray pipes 208 respectively. The paint pumps 209, hoses 211 and spray pipes 208 can realize the synchronous spraying of the upper and lower surfaces of the I-shaped steel structure. In use, the paint to be sprayed is poured into the storage tank 210, and then the steel structure to be sprayed is placed inside the frame 1 and continuously pushed. The servo motor 201 is started, causing the first lead screw 202 and the first pulley 204 to rotate, which in turn causes the second lead screw 203 to rotate synchronously through the belt. When the first lead screw 202 and the second lead screw 203 rotate, they will drive the two moving frames 207 to move along the length direction of the two stabilizing rods 206 respectively. The paint pump 209 is started to extract the paint from the storage tank 210 and spray it out through the hose 211 and the spray pipe 208. The two spray pipes 208 are vertically distributed and the spraying direction is towards each other. Through the continuous reciprocating movement of the moving frame 207, the upper and lower surfaces of the steel structure can be continuously sprayed with paint.

[0030] like Figure 3 and Figure 4As shown, the conveying assembly 3 includes a reduction motor 301 bolted to the outer wall of the frame 1. A first friction roller 302 is coaxially mounted on the output end of the reduction motor 301. A second friction roller 303 is rotatably connected inside the frame 1. A second pulley 304 is fixedly connected to one side of both the first and second friction rollers 302 and 303 extending outside the frame 1. A second belt 305 is mounted on the outer wall of the second pulley 304. The I-shaped steel structure to be painted is placed inside the frame 1, with the bottom of the steel structure in contact with the outer wall of the second friction roller 303. The reduction motor 301 is started, causing the first friction roller 302 and the second pulley 304 to rotate. The second belt 305 causes the second friction roller 303 to rotate in the same direction. The high surface friction of the first and second friction rollers 302 and 303 allows for continuous and stable movement of the steel structure, facilitating subsequent painting work.

[0031] like Figure 4 As shown, multiple flexible curtains 4 are installed on opposite sides of the frame 1. A fan 5 is bolted to the top of the frame 1, and a fixed pipe 6 is installed at the output end of the fan 5. A resistance wire 7 is installed on the inner wall of the fixed pipe 6, and the end of the fixed pipe 6 away from the fan 5 extends into the interior of the frame 1. Before spraying the steel structure, the fan 5 can be turned on and the resistance wire 7 can be connected to an external power source. The fan 5 can blow the heat generated by the resistance wire 7 into the frame 1 through the fixed pipe 6. The warm environment helps the paint to form a uniform film on the surface of the steel structure, thereby improving the quality and durability of the coating. The flexible curtains 4 can maintain the temperature inside the frame 1 without affecting the transmission of the steel structure.

[0032] like Figure 5 As shown, an extension frame 8 is fixedly connected to the top of the frame 1. An exhaust fan 9 is installed on the inner wall of the extension frame 8, and the extension frame 8 is connected to the interior of the frame 1. When the exhaust fan 9 is turned on, the odor generated by the paint spraying inside the frame 1 can be expelled from the frame 1, and the internal temperature of the frame 1 can be prevented from becoming too high.

[0033] like Figure 5 As shown, a placement frame 10 is fixedly connected to the top of the extension frame 8, and a filter frame 11 is slidably connected inside the placement frame 10. Multiple ventilation holes 12 are provided throughout the interior of both the placement frame 10 and the filter frame 11. Activated carbon is placed in the filter frame 11, and then the filter frame 11 is slid into the placement frame 10. Odors blown out by the ventilation fan 9 will enter the filter frame 11 through the ventilation holes 12, be adsorbed by the activated carbon, and then be discharged from the placement frame 10, thus preventing environmental pollution.

[0034] like Figure 5As shown, an extension post 13 is fixedly connected to one side of the placement frame 10, and a baffle 14 is hinged to the outer wall of the extension post 13. The extension post 13 and the baffle 14 can limit the filter frame 11 that slides into the placement frame 10, preventing the filter frame 11 from opening arbitrarily.

[0035] like Figure 2 As shown, slide plates 15 are fixedly connected to both sides of the two movable frames 207, and protective frames 16 are fixedly connected to the inner walls of the opposite sides of the frame 1. The slide plates 15 are slidably connected to the inside of the protective frames 16. The slide plates 15 will slide into the protective frames 16 as the movable frames 207 move, which can block the sprayed paint during the spraying process and prevent the first lead screw 202 and the second lead screw 203 from adhering to the paint.

[0036] Specifically, when using this steel structure processing and spraying device: start the fan 5 and connect the resistance wire 7 to the external power supply. The fan 5 can blow the heat generated by the resistance wire 7 into the frame 1 through the fixed pipe 6 (e.g., Figure 4 (As shown); Place the I-shaped steel structure to be painted inside the frame 1, and make the bottom of the steel structure contact the outer wall of the second friction roller 303. Start the reduction motor 301 to make the first friction roller 302 and the second pulley 304 rotate, and make the second friction roller 303 rotate in the same direction through the second belt 305. The surface friction of the first friction roller 302 and the second friction roller 303 is large, which can drive the steel structure to move continuously and stably (as shown). Figure 3 and Figure 4 (As shown); pour the paint to be sprayed into the storage tank 210, start the servo motor 201 to make the first lead screw 202 and the first pulley 204 rotate, and then make the second lead screw 203 rotate synchronously through the belt. When the first lead screw 202 and the second lead screw 203 rotate, they will drive the two moving frames 207 to move along the length direction of the two stabilizing rods 206 respectively. Start the paint pump 209 to draw the paint from the storage tank 210 and spray it out through the hose 211 and the spray pipe 208. The two spray pipes 208 are vertically distributed and the spraying direction is towards each other. Through the continuous reciprocating movement of the moving frame 207, the upper and lower surfaces of the steel structure can be continuously sprayed with paint (such as...). Figure 2 (As shown); Activated carbon is placed in the filter frame 11, and then the filter frame 11 is slid into the placement frame 10. Odors blown out by the ventilation fan 9 will enter the filter frame 11 through the vent 12, be adsorbed by the activated carbon, and then be discharged from the placement frame 10, avoiding environmental pollution (e.g. Figure 4 and Figure 5 (As shown).

[0037] All technical features in this embodiment can be freely combined according to actual needs.

[0038] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
