Description

Technical Field

[0001] This utility model relates to the field of column spraying technology, and in particular to a spraying tool for bridge steel structure guardrail columns. Background Technology

[0002] Bridge steel structure guardrail posts are mainly used to support and fix the guardrails on both sides of the bridge, ensuring the safety of vehicles and pedestrians, as well as the structural stability of the bridge. Guardrail posts are typically made of steel or other metal materials, possessing high strength, corrosion resistance, and impact resistance. Before the steel structure guardrails are officially installed on the bridge, they are usually sprayed with anti-corrosion coating to form the first protective film. Existing spraying technologies, such as the road and bridge construction surface spraying device disclosed in patent CN221472299U, while improving work efficiency through the cooperation of a mixing shaft, support, cylindrical shaft, gears, moving frame, and spray pipe, suffer from uneven coating when encountering irregular or inclined surfaces. This results in an excessively thick coating on the irregular or inclined surfaces, while other areas may be thin or completely uncoated. Therefore, this utility model proposes a bridge steel structure guardrail post spraying fixture to solve the aforementioned technical problems. Utility Model Content

Detailed Implementation

[0019] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0020] A type of spray painting tool for bridge steel structure guardrail posts, such as Figures 1-5As shown, the device includes a base 101, a first fixing block 204 fixed to the top surface of the base 101, a temporary storage box 205 rotatably connected to the first fixing block 204, the temporary storage box 205 being driven to rotate by a first motor 206 mounted on the bottom surface of the base 101, a fixing plate 201 fixed to the temporary storage box 205 via a fixing ring 203, four first sliding grooves 2011 provided on the fixing plate 201, sliding blocks 219 slidably connected within the first sliding grooves 2011, and a nozzle 202 connected to the side of the sliding block 219 via a rotating component. Specifically, the rotating component includes a rotating connection... A rotating block 212 is located on one side of the sliding block 219. The rotating block 212 is driven to rotate by a second motor 220 installed on the other side of the sliding block 219. A second sliding groove 2121 is provided on the rotating block 2121. A circular arc plate 216 is symmetrically slidably connected in the second sliding groove 2121. A third lead screw 217 is rotatably connected in the second sliding groove 2121. A knob 218 is fixed to one end of the third lead screw 217. The knob 218 is rotatably connected to the side of the rotating block 212. Rotating the knob 218 can clamp the nozzle 202 through the two circular arc plates 216. By rotating knob 218, the two arc plates 216 can be moved further apart or closer together, facilitating the replacement of the spray head 202. The spray head 202 is connected to the temporary storage box 205 via a hose, allowing it to swing up and down, thus changing the spray angle or expanding the spraying area. The sliding block 219 is driven by a first driving component to slide within the first sliding groove 2011. Specifically, the first driving component includes symmetrically fixed components to the first sliding groove 2011. The groove 2011 has two second fixing blocks 211 on both sides. A first guide rod 213 is fixedly connected to the two second fixing blocks 211. The first guide rod 213 is slidably connected to the sliding block 219. A first lead screw 214 is rotatably connected between the two second fixing blocks 211. The first lead screw 214 is driven by a first motor 215 installed on one of the second fixing blocks 211 to achieve rotation. The first lead screw 214 is threadedly connected to the sliding block 219. This allows the nozzle 202 to move, thereby adjusting the distance between the nozzle 202 and the spraying surface to adapt to different curvatures.

[0021] Therefore, when the first motor 206 is started, its output shaft drives the temporary storage box 205 to swing, which in turn drives the fixed plate 201 to swing through the fixed ring 203, thus enabling all the nozzles 202 on the fixed plate 201 to swing. When the first motor 215 is started, its output shaft drives the first lead screw 214 to rotate, which in turn causes the sliding block 219 to move through the threaded connection, thus enabling the nozzles 202 to move. When the second motor 220 is started, its output shaft drives the rotating block 212 to rotate, thus changing the elevation angle of the nozzles 202 during spraying. In this way, through the action of the first motor, the first motor, and the second motor on the nozzles, the distance between the nozzles 202 and the spraying surface can be adjusted to adapt to different curvatures and avoid the coating being too thick on irregular surfaces or in some areas.

[0022] Furthermore, the system also includes a clamping assembly for holding objects. The clamping assembly includes a squeegee 301 rotatably connected to the base 101. The squeegee 301 has squeegee holes 3011, through which excess paint is discharged to the outside. A second motor 307 is mounted on the bottom surface of the base 101. The second motor 307 drives the squeegee 301 to rotate via a synchronous belt component 306. A third slide groove 3012 is provided on the squeegee 301. Flexible clamps 302 are symmetrically slidably connected within the third slide groove 3012. The flexible clamps 302 are driven by a second driving component to move closer or further apart. The flexible clamps 302 are prior art and will not be described further. Specifically, the second driving component includes third fixing blocks 303 symmetrically fixed to the bottom surface of the squeegee 301. A second guide rod 305 is fixed between the two third fixing blocks 303. The two flexible clamps 302 are slidably connected to the second guide rod 305. A second lead screw 304 is rotatably connected between two third fixing blocks 303. The second lead screw 304 is driven to rotate by a third motor 308 mounted on the third fixing blocks 303. A flexible clamp 302 is threadedly connected to the second lead screw 304. Thus, the bridge steel structure column used in this utility model is hollow. The flexible clamp 302 clamps the column inside the column and places it on the sprue plate 301. Then, the third motor 308 is started, and the output shaft of the third motor 308 drives the second lead screw 304 to rotate. The second lead screw 304, through the threaded connection, causes the two flexible clamps 302 to move away from or towards each other, thereby fixing the column. Then, according to the actual situation, the second motor 307 is started. The second motor 307 drives the sprue plate 301 to rotate through the synchronous belt component 306, which in turn drives the column to rotate, allowing the column to be sprayed on all surfaces as needed.

[0023] Furthermore, it also includes a mixing assembly for mixing materials. The mixing assembly includes a mixing drum 401 and a pump body 102 installed on the top surface of the base 101. The pump body 102 is connected to the mixing drum 401 through a pipe and to the temporary storage tank 205 through a hose. A mixing rod 402 is rotatably connected inside the mixing drum 401. A third motor 404 is installed on the bottom surface of the base 101. The output shaft of the third motor 404 is fixedly connected to the mixing rod 402. A hopper 403 is connected to the top surface of the mixing drum 401. Thus, the raw materials enter the mixing drum 401 through the hopper 403. Then, the third motor 404 is started, and the output shaft of the third motor 404 drives the mixing rod 402 to rotate, mixing the raw materials into a coating. Then, the coating is extracted by the pump body 102 and transported to the temporary storage tank 205, and then sprayed out by the nozzle 202.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
