Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline processing, and in particular relates to a pipeline anti-corrosion layer coating device. Background Art

[0002] Pipelines are mainly used to transport liquids and gases. In order to extend the service life of pipelines, it is usually necessary to perform anti-corrosion treatment on the surface of the pipelines. The existing technology usually requires workers to spray anti-corrosion coatings on the surface of the pipelines with handheld spray guns, but manual operation often leads to uneven spraying and poor spraying effect.

[0003] A Chinese patent with publication number CN217940581U discloses an anti-corrosion coating spraying device for pipe materials. The solution includes a mounting frame, a spraying mechanism, a supporting mechanism and a driving mechanism. The driving mechanism includes a motor and a screw rod. A movable seat is provided on the outer sleeve of the screw rod. The spraying mechanism is arranged on the movable seat. The supporting mechanism includes a first chuck and a second chuck. The above solution enables the first chuck and the second chuck to clamp the pipe, and uses the motor to drive the screw rod to rotate, which drives the movable seat to move and also drives the first chuck to rotate, thereby improving the spraying quality.

[0004] When the above scheme is in use, when the motor drives the screw rod to rotate to displace the movable seat, the first chuck is also driven to rotate. When the surface of the side of the pipe mouth away from the movable seat in the initial state rotates to be close to the movable seat, the movable seat moves away from the pipe mouth in the horizontal direction, resulting in that when the above scheme moves the movable seat unidirectionally, the surface of the side of the pipe mouth away from the movable seat in the initial state cannot be effectively sprayed, and the spraying area cannot cover the entire outer surface of the pipe, resulting in a poor spraying effect. Utility Model Content

[0005] The utility model aims to provide a pipeline anti-corrosion coating device to solve the problem of poor spraying effect in the above scheme.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipeline anti-corrosion coating device comprises a base, a movable base, a mounting base, a chuck and a first motor, a first support frame is fixedly arranged on the right side of the top of the base, a worm is arranged on the rear side of the first support frame for horizontal rotation, the movable base is slidably arranged on the top of the base along the left and right directions, a second support frame is fixedly arranged on the top of the movable base, the mounting base is fixedly arranged above the base, a slider is slidably hung below the mounting base, a nozzle is fixedly arranged at the bottom of the slider, a propulsion mechanism is arranged in the mounting base, the propulsion mechanism is connected to the worm gear through a transmission mechanism, and is used to drive the slider to move intermittently, two chucks are symmetrically arranged, and are rotatably embedded in the first support frame and the second support frame respectively, a worm wheel cooperating with the worm is fixedly arranged on the outer wall of the chuck on the right side along its axial direction, and the first motor is fixedly arranged on the right side of the first support frame and is connected to the worm gear transmission.

[0008] The principle and effect of this technical solution:

[0009] The pipe is clamped between the two chucks so that the claws of the chucks are pressed against the inner wall of the pipe, and the first motor is driven to rotate the worm. On the one hand, it drives the worm wheel and the chuck to rotate, and then drives the pipe to rotate. On the other hand, the slider is driven to move through the transmission mechanism and the propulsion mechanism. The slider moves once every time the pipe rotates one circle.

[0010] Through the above arrangement, the slider can be displaced after the pipeline rotates one circle, so that the utility model can spray the entire outer surface of the pipeline when the slider moves unidirectionally, thereby improving the spraying quality and solving the problem of poor spraying effect in the above solution.

[0011] In the utility model, the propulsion mechanism includes a U-shaped frame and a plurality of levers fixedly arranged at intervals at the bottom of the U-shaped frame, the transmission mechanism includes a first transmission wheel, a first transmission belt, a second transmission wheel, a transmission shaft, a third transmission wheel, a second transmission belt and a fourth transmission wheel, the first transmission wheel is fixedly arranged at the rear side of the worm, the second transmission wheel is rotatably arranged in the mounting seat and is located above the first transmission wheel, the first transmission belt is wound around the first transmission wheel and the second transmission wheel, the transmission shaft is fixedly arranged at the front side of the second transmission wheel, the third transmission wheel is rotatably arranged in the mounting seat and fixedly arranged at the front side of the transmission shaft, the fourth transmission wheel is rotatably arranged in the mounting seat, the second transmission belt is wound around the third transmission wheel and the fourth transmission wheel, the front sides of the third transmission wheel and the fourth transmission wheel are both eccentrically fixed with round pins, and the tops on the left and right sides of the U-shaped frame are respectively rotatably sleeved on the two round pins.

[0012] The principle and effect of this technical solution:

[0013] The first motor drives the worm to rotate, and the worm drives the worm wheel and the first transmission wheel to rotate at the same time, and then drives the third transmission wheel and the fourth transmission wheel to rotate clockwise through the first transmission belt, the second transmission wheel, the transmission shaft and the second transmission belt. During the process of the round pin rotating from the rightmost side to the leftmost side, the lever is driven to move leftward, thereby pushing the slider to move. When the round pin is reset from the leftmost side to the rightmost side, the lever does not contact the slider, and the slider is in a stationary state. When the round pin rotates from the rightmost side to the leftmost side again, the next lever continues to push the slider to move, and this operation is repeated until the entire outer surface of the pipeline is sprayed.

[0014] Through the above arrangement, the purpose of intermittent movement of the slider is achieved, and the practicality of the utility model is improved.

[0015] In the utility model, a groove is arranged horizontally on the top of the base, a screw is rotatably arranged in the groove, a protrusion is fixedly arranged on the bottom of the movable seat, the protrusion is slidably embedded in the groove and fitted on the screw, a second motor is fixedly arranged on the left side of the base, and the screw is transmission-connected to the output shaft of the second motor.

[0016] In the utility model, a rotating shaft is rotatably arranged above the base on the right side of the groove, a shielding cloth is wound around the rotating shaft, a cross bar is fixedly arranged on the right side of the movable seat, and one end of the shielding cloth is sleeved on the cross bar.

[0017] In the utility model, a mounting block is fixedly arranged on the front and rear sides of the top of the base on the right side of the groove, the mounting block has an inner cavity, the two ends of the rotating shaft are respectively rotatably inserted in the two inner cavities, and a clockwork spring is arranged between the side wall of the rotating shaft and the side wall of the inner cavity.

[0018] The principle and effect of this technical solution:

[0019] Because the groove limits the rotation of the protrusion, the protrusion is displaced as the screw rotates, thereby changing the distance between the two chucks so that the two chucks clamp the pipe to be sprayed. When the moving seat is away from the first support frame to reserve operating space for placing the pipe, the cross bar extends the cover cloth and drives the rotating shaft to rotate. At this time, the clockwork spring has a certain elastic force. When the moving seat is close to the first support frame to clamp the pipe, the rotating shaft rotates under the action of the clockwork spring to tighten the cover cloth.

[0020] Through the above arrangement, the cover cloth can receive the excess anti-corrosion paint dripping from the pipe surface to prevent it from dripping into the groove and adhering to the screw, thereby ensuring the smoothness of the movement of the protrusion and improving the practicality of the utility model.

[0021] In the utility model, a through hole is provided along the axial direction of the side wall of the chuck, an air outlet is fixedly provided laterally on the right side of the chuck above the base, the air outlet is penetrated through the worm gear and the through hole of the chuck on the right side, an exhaust fan is fixedly provided inside the air outlet, a fixing rod is fixed laterally above the movable seat, the right end of the fixing rod is inserted into the through hole of the chuck on the left side, and a heater is fixedly provided on the right end of the fixing rod.

[0022] The principle and effect of this technical solution:

[0023] After the spraying work is completed, the heater and the exhaust fan are started. The exhaust fan draws the air in the pipeline out of the air outlet, forming a negative pressure in the pipeline. The outside air flows into the pipeline through the through hole of the chuck on the left side. The air is heated to form hot air when passing through the heater. The hot air flows into the pipeline to heat the pipeline.

[0024] Through the above arrangement, the pipeline can be heated, the drying speed of the anti-corrosion coating on the pipeline surface can be accelerated, and the drying efficiency can be improved.

[0025] In the utility model, a controller is fixedly arranged on the side wall of the sliding block, and the controller is electrically connected to the nozzle.

[0026] The principle and effect of this technical solution:

[0027] When the slider moves, the controller closes the nozzle, and when the slider stops moving, the controller opens the nozzle to perform spraying.

[0028] Through the above-mentioned arrangement, it is possible to avoid the nozzle from continuously spraying the pipe during movement, thereby avoiding uneven spraying caused by repeated spraying of part of the pipe, further improving the spraying quality and the practicality of the utility model.

[0041] In this embodiment, a rotating shaft 80 is rotatably arranged above the base 10 on the right side of the groove 13 , a cover cloth 81 is arranged around the rotating shaft 80 , a cross bar 22 is fixedly arranged on the right side of the movable base 20 , and one end of the cover cloth 81 is sleeved on the cross bar 22 .

[0042] In this embodiment, a mounting block 16 is fixedly provided on the front and rear sides of the top of the base 10 on the right side of the groove 13, and the mounting block 16 has an inner cavity 161.

[0043] In this embodiment, a through hole 62 is provided along the axial direction of the side wall of the chuck 60, and an air outlet tube 17 is fixedly provided laterally on the right side of the chuck 60 above the base 10.

[0044] In this embodiment, a controller 312 is fixedly disposed on the side wall of the slider 31 , and the controller 312 is electrically connected to the nozzle 311 .

[0045] The specific implementation process is as follows:

[0046] The pipeline is clamped between the two chucks 60 so that the claws of the chucks 60 are pressed against the inner wall of the pipeline, and the first motor 70 is driven to drive the worm 12 to rotate. On the one hand, it drives the worm wheel 61 and the chuck 60 to rotate, and then drives the pipeline to rotate. On the other hand, the slider 31 is driven to move through the transmission mechanism and the propulsion mechanism. The slider 31 moves once every time the pipeline rotates one circle.

[0047] The first motor 70 drives the worm 12 to rotate, and the worm 12 drives the worm wheel 61 and the first transmission wheel 51 to rotate at the same time, and then drives the third transmission wheel 55 and the fourth transmission wheel 57 to rotate clockwise through the first transmission belt 52, the second transmission wheel 53, the transmission shaft 54 ​​and the second transmission belt 56. During the process of the round pin 58 rotating from the rightmost side to the leftmost side, the lever 42 is driven to move leftward, thereby pushing the slider 31 to move. When the round pin 58 is reset from the leftmost side to the rightmost side, the lever 42 does not contact the slider 31, and the slider 31 is in a stationary state. When the round pin 58 rotates from the rightmost side to the leftmost side again, the next lever 42 continues to push the slider 31 to move, and this operation is repeated until the entire outer surface of the pipeline is sprayed.

[0048] Because the groove 13 limits the rotation of the protrusion 24, the protrusion 24 is displaced as the screw 14 rotates, thereby changing the distance between the two chucks 60 so that the two chucks 60 clamp the pipe to be sprayed. When the movable seat 20 is away from the first support frame 11 to reserve operating space for placing the pipe, the cross bar 22 extends the cover cloth 81 and drives the rotating shaft 80 to rotate. At this time, the clockwork spring 162 has a certain elastic force. When the movable seat 20 approaches the first support frame 11 to clamp the pipe, the rotating shaft 80 rotates under the action of the clockwork spring 162 to tighten the cover cloth 81.

[0049] After the spraying work is completed, the heater 231 and the exhaust fan 171 are started. The exhaust fan 171 draws the air in the pipeline from the air outlet 17, forming a negative pressure in the pipeline, and the outside air flows into the pipeline through the through hole 62 of the chuck 60 on the left side. The air is heated to form hot air when passing through the heater 231, and the hot air flows into the pipeline to heat the pipeline.

[0050] When the slider 31 moves, the controller 312 closes the nozzle 311 , and when the slider 31 stops moving, the controller 312 opens the nozzle 311 to perform the spraying operation.
