Description

A pipe pile spraying device

Technical Field

The invention belongs to the technical field of spraying, in particular to a pipe pile spraying device.

Background technique

Pipe piles are a kind of hollow long strip engineering material. Pipe piles are usually used in construction, roads, bridges and other projects. Pipe piles are used for support in engineering because of their strong bearing capacity. Therefore, pipe piles need to be exposed to the air for a long time. In order to prevent corrosion and other conditions during the use of pipe piles, the outside of the pipe piles will be sprayed with topcoat during the production process.

The prior art also proposes some solutions. For example, a patent application with publication number CN111282744B discloses a topcoat spraying system for a pipe pile end plate, which allows two pipe pile end plates to be sprayed with paint at the same time by setting two channels.

When the above-mentioned technical solution is in use, the two pipe pile end plates are painted at the same time. However, during the painting process, the upper and lower surfaces of the pipe pile end plates need to be painted separately, which may cause the surface of the pipe pile end plates to be not painted evenly. In addition, during the production process, there may be dirt and impurities on the surface of the pipe pile end plates. During the painting process, the dirt and impurities will block the pipe pile end plates, resulting in the inability of the topcoat to cover the outer surface. The protective effect during use will be greatly affected, and the distance between different pipe piles and the nozzle will change, resulting in the uniformity of the sprayed paint surface being affected.

During operation, the exterior of the pipe pile needs to be sprayed with a topcoat before use. The topcoat makes the pipe pile more durable. Before spraying, the pipe pile is placed between the active rotating rod 22 and the driven rotating rod 23, and then the first motor 21 is started to drive the active rotating rod 22 to rotate. The active rotating rod 22 rotates to drive the pipe pile to rotate, and at the same time, the reciprocating screw rod 31 rotates to drive the moving sleeve 32 to move. The moving sleeve 32 moves to drive the spraying pipe 36 and the cleaning structure to move at the same time. The cleaning structure cleans the surface of the pipe pile in advance. When the cleaning After the cleaning structure is cleaned, the reciprocating screw rod 31 drives the movable sleeve 32 to move in the opposite direction. At this time, the liquid extraction pump 361 is started to extract the topcoat liquid inside the liquid storage tank 362, and then input it into the inside of the spray pipe 36. At this time, the spray pipe 36 can spray the topcoat onto the surface of the pipe pile through the spray nozzle 364. During the uniform movement of the spray nozzle 364 for painting, the active rotating rod 22 drives the pipe pile to rotate at a uniform speed, so that the spray nozzle 364 can evenly spray paint on the surface of the pipe pile. After the painting is completed, the pipe pile is taken out through the discharge structure.

As shown in FIG1 , a first pulley 221 is fixed to one end of the active rotating rod 22 away from the first motor 21, a second pulley 311 is fixed to one end of the reciprocating screw rod 31 close to the first pulley 221, and a belt 222 is sleeved on the outer sides of the first pulley 221 and the second pulley 311;

The active rotating rod 22 drives the first pulley 221 to rotate during its rotation, and the first pulley 221 drives the second pulley 311 to rotate via the belt 222, so that the active rotating rod 22 can rotate and simultaneously drive the reciprocating screw rod 31 to rotate.

During use, the pipe pile will be placed between the active rotating rod 22 and the driven rotating rod 23. During this process, the pipe pile will push the support roller 363 upward, and the support roller 363 will push the support plate 351 upward. At this time, the support plate 351 can drive the spray nozzle 364 to adjust the distance between it and the pipe pile, so that the distance between pipe piles of different diameters and the spray nozzle 364 can be kept consistent, so that the thickness of the topcoat on the surface of the pipe pile is uniform.

As shown in FIG6 , the top ends of the spray pipe 36 and the liquid pump 361 are fixedly connected to the bottom end of the support plate 351 , and the bottom end of the liquid storage tank 362 is fixedly connected to the top end of the support plate 351 ;

The support plate 351 can drive the spray pipe 36 , the liquid pump 361 and the liquid storage tank 362 to move synchronously with the movement of the movable sleeve 32 .

As shown in FIG. 7 , the cleaning structure includes a cleaning roller 37 disposed on a side of the support plate 351 away from the support roller 363, a lifting frame 373 is disposed outside the cleaning roller 37, the cleaning roller 37 is rotatably connected to the inside of the lifting frame 373, bristles 371 are disposed on the outside of the cleaning roller 37, and transmission rollers 372 are fixed on both sides of the cleaning roller 37;

Before painting, a cleaning structure is needed to pre-clean the surface of the pipe pile. At this time, the active rotating rod 22 drives the pipe pile to rotate, and at the same time, the active rotating rod 22 drives the reciprocating screw 31 to rotate synchronously, and the reciprocating screw 31 drives the moving sleeve 32 to move. During the movement, the transmission roller 372 is attached to the surface of the pipe pile. The rotation of the pipe pile drives the transmission roller 372 to rotate at the same time. When the transmission roller 372 rotates, it drives the cleaning roller 37 to rotate. When the cleaning roller 37 rotates, it drives the bristles 371 to flip over. The bristles 371 flip over to clean the surface of the pipe pile, which can make the surface of the pipe pile cleaner and prevent uneven spraying due to dirt and impurities during spraying.

As shown in FIG. 7 , the bristles 371 are provided in a plurality of groups, and the plurality of groups of bristles 371 are evenly spaced and distributed on the outside of the cleaning roller 37 , and the outer diameter of the driving roller 372 is larger than the outer diameter of the cleaning roller 37 ;

Providing multiple groups of bristles 371 can make them contact with the surface of the pile more frequently, thereby increasing the number of cleaning times.

As shown in FIGS. 7 and 8 , a connecting frame 378 is fixed to one end of the lifting frame 373, and a cleaning comb 379 is fixed to one end of the bottom of the connecting frame 378 close to the cleaning roller 37. A plurality of cleaning combs 379 are provided, and the plurality of cleaning combs 379 are evenly spaced and distributed between two adjacent groups of bristles 371;

When the bristles 371 clean the dirt on the surface of the pipe pile, the dirt may accumulate, causing the cleaning effect of the bristles 371 to deteriorate. When the bristles 371 are turned over, the cleaning comb 379 is inserted between the bristles 371. At this time, the dirt accumulated on the surface of the bristles 371 is removed to prevent the dirt from affecting the subsequent cleaning effect of the bristles 371.

As shown in FIG7 , a lifting block 374 is fixed to one side of the lifting frame 373 close to the support plate 351, a guide frame 375 is fixed to one side of the support plate 351 close to the lifting frame 373, a third motor 376 is installed on the top of the guide frame 375, a second threaded rod 377 is fixed to the end of the rotating shaft of the third motor 376, the lifting block 374 forms a sliding structure inside the guide frame 375, and a threaded connection is formed between the lifting block 374 and the second threaded rod 377;

After the bristles 371 have cleaned the pipe pile, paint is carried out. At this time, the bristles 371 need to be separated from the pipe pile, and the third motor 376 is started to drive the second threaded rod 377 to rotate. The second threaded rod 377 drives the lifting block 374 to rise from the inside of the guide frame 375, and the lifting block 374 drives the lifting frame 373 to rise. At this time, the lifting frame 373 can drive the cleaning roller 37 to rise to separate the bristles 371 from the pipe pile, and then paint can be carried out. During the painting process, the bristles 371 will not affect the spraying effect.

As shown in FIGS. 2 to 4 , the discharge structure includes a movable groove 11 provided inside the support platform 1, a flip plate 12 is rotatably connected inside the movable groove 11, a buffer spring 13 is fixed to the bottom end of the flip plate 12, and the bottom end of the buffer spring 13 is fixedly connected to the support platform 1, a slide groove 234 is provided on one side of the first support frame 2 close to the driven rotating rod 23, a first threaded rod 232 is rotatably connected inside the slide groove 234, a second motor 233 is installed inside the first support frame 2, and the end of the rotating shaft of the second motor 233 is fixedly connected to the first threaded rod 232, both sides of the driven rotating rod 23 are rotatably connected to slider columns 231, the slider columns 231 are movably connected inside the slide groove 234, and a threaded connection is formed between the slider columns 231 and the first threaded rod 232;

After the pipe pile is painted, it is removed, and the second motor 233 is started to rotate to drive the first threaded rod 232 to rotate. The first threaded rod 232 drives the slider column 231 to move inside the slide groove 234. At this time, the slider column 231 drives the driven rotating rod 23 to move away from the active rotating rod 22. At this time, the pipe pile falls downward, and the pipe pile falls on the top of the flip plate 12. The flip plate 12 is flipped under force. At this time, the buffer spring 13 buffers the flip plate 12, and then the pipe pile slides out of the inside of the movable groove 11 along the flip plate 12, and then the elastic force of the buffer spring 13 pushes the flip plate 12 to return to its original position.

As shown in FIG3 , the inner part of the flip plate 12 is rotatably connected with guide rollers 121, and the guide rollers 121 are evenly spaced and distributed inside the flip plate 12;

When the pipe pile falls on the flip plate 12 and slides down, the guide roller 121 can roll inside the flip plate 12. The rolling of the guide roller 121 reduces the friction between the pipe pile and the flip plate 12, making it easier to take out the pipe pile.

Working principle: When working, the exterior of the pipe pile needs to be sprayed with topcoat before use. The topcoat makes the pipe pile more durable. Before spraying, the pipe pile is placed between the active rotating rod 22 and the driven rotating rod 23. The cleaning structure is used to pre-clean the surface of the pipe pile. The first motor 21 is started to drive the active rotating rod 22 to rotate. The active rotating rod 22 rotates to drive the pipe pile to rotate. During the rotation of the active rotating rod 22, the first pulley 221 is driven to rotate. The first pulley 221 drives the second pulley 311 to rotate through the belt 222. The active rotating rod 22 can rotate while synchronously driving the reciprocating screw 31 to rotate. The reciprocating screw 31 rotates. The movable sleeve 32 is driven to move, and the movement of the movable sleeve 32 drives the spray pipe 36 and the cleaning structure to move at the same time. During the movement, the transmission roller 372 is attached to the surface of the pipe pile. The rotation of the pipe pile drives the transmission roller 372 to rotate. When the transmission roller 372 rotates, it drives the cleaning roller 37 to rotate. When the cleaning roller 37 rotates, it drives the bristles 371 to flip. The bristles 371 flip to clean the surface of the pipe pile. When the bristles 371 clean the dirt on the surface of the pipe pile, the dirt may accumulate, causing the cleaning effect of the bristles 371 to deteriorate. When the bristles 371 flip, the cleaning comb 379 is inserted between the bristles 371. At this time, the dirt accumulated on the surface of the bristles 371 is removed.

When the cleaning structure is finished, the reciprocating screw rod 31 drives the movable sleeve 32 to move in the opposite direction, and the liquid pump 361 is started to extract the topcoat liquid in the liquid storage tank 362, and then input it into the inside of the spray tube 36. At this time, the spray tube 36 can spray the topcoat onto the surface of the pipe pile through the spray nozzle 364. During the uniform movement of the spray nozzle 364, the active rotating rod 22 drives the pipe pile to rotate at a uniform speed, so that the spray nozzle 364 can spray paint evenly on the surface of the pipe pile. During the placement of the pipe pile between the active rotating rod 22 and the driven rotating rod 23, the pipe pile will push the support roller 363 upward, and the support roller 363 pushes the support plate 351 upward. At this time, the support plate 351 can drive the spray nozzle 364 to adjust the distance between it and the pipe pile, so that the distance between the pipe piles of different diameters and the spray nozzle 364 can be kept consistent, so as to make the topcoat thickness on the surface of the pipe pile uniform.

After the pipe pile is painted, the second motor 233 is started to rotate and drive the first threaded rod 232 to rotate. The first threaded rod 232 drives the slider column 231 to move inside the slide groove 234. At this time, the slider column 231 drives the driven rotating rod 23 to move in the direction away from the active rotating rod 22. At this time, the pipe pile falls downward and falls on the top of the flip plate 12. The flip plate 12 is flipped under force. At this time, the buffer spring 13 buffers the flip plate 12, and then the pipe pile slides out of the inside of the movable groove 11 along the flip plate 12. The friction between the pipe pile and the flip plate 12 is reduced by the rolling of the guide roller 121. Then the elastic force of the buffer spring 13 pushes the flip plate 12 to return to its original position.
