DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 As shown, an automatic cleaning device for steel pipes includes multiple transmission mechanisms 1, a feeding mechanism 2, an outer wall cleaning mechanism 3, a bearing mechanism 4, a pouring mechanism 5, an inner wall brushing mechanism 6 and a unloading mechanism 7.

[0021] like Figure 1 As shown, a plurality of conveying mechanisms 1 are arranged at intervals on the ground and are used to support and convey steel pipes. A loading mechanism 2 is used to load steel pipes and transfer them to the front conveying mechanism 1. An outer wall cleaning mechanism 3 is located between the two rear conveying mechanisms 1 and is used to clean the outer wall of the steel pipe.

[0022] like Figure 1 , Figure 2 As shown, the bearing mechanism 4 includes a first bearing component 41 and a second bearing component 42. The first bearing component 41 and the second bearing component 42 are arranged in parallel and are used to bear the steel pipe. The first bearing component 41 is located behind the rearmost transmission mechanism 1, and the second bearing component 42 is lower than the first bearing component 41.

[0023] like Figure 2 As shown, the first bearing assembly 41 and the second bearing assembly 42 each include a plurality of bearing seats 43 and bearing wheels 44. The bearing seats 43 are vertically and spaced apart on the ground, and the bearing wheels 44 are grouped in pairs and are rotatably connected to the bearing seats 43 and used to support the steel pipes.

[0024] like Figure 2 As shown, the unloading mechanism 5 is used to guide the steel pipe from the first bearing assembly 41 to the second bearing assembly, and the inner wall brushing mechanism 6 is located at both ends of the second bearing assembly and is used to clean the inner wall of the steel pipe. The unloading mechanism 7 is used to unload the cleaned steel pipe from the bearing mechanism 4.

[0025] When cleaning the steel pipes, the feeding mechanism 2 is used to transport the steel pipes one by one to the transmission mechanism 1, and the transmission mechanism 1 is used to transport the steel pipes so that the steel pipes enter the outer wall cleaning mechanism 3 to achieve automatic cleaning of the outer wall of the steel pipe.

[0026] Then, the cleaned steel pipe is transferred to the first bearing assembly 41 on the bearing mechanism 4, and then the steel pipe on the first bearing assembly 41 is introduced to the second bearing assembly 42 by the unloading mechanism 5. Then, the inner wall of the steel pipe on the second bearing assembly 42 is cleaned by the inner wall brushing mechanism 6. After cleaning, the cleaned steel pipe on the second bearing assembly 42 is unloaded by the unloading mechanism 7, and then continuously transferred to the next step to realize continuous production and processing.

[0027] Therefore, by setting up highly automated cleaning equipment, automatic loading, automatic transmission, automatic outer wall cleaning, automatic inner wall brushing and automatic unloading of steel pipes can be achieved, replacing traditional manual cleaning, saving labor, shortening cleaning time, and improving cleaning effects and cleaning efficiency.

[0028] like Figure 1 , Figure 3 , Figure 4 As shown, the transmission mechanism 1 includes a transmission seat 11, a transmission platform 12, an active transmission wheel 13 and a driven transmission wheel 14. The transmission seat 11 is vertically arranged on the ground, and the center line has an angle of 10°-20° with the traveling direction of the steel pipe.

[0029] like Figure 1 , Figure 3 , Figure 4 As shown, the transfer platform 12 is horizontally arranged on the transfer base 11 , one end of the transfer platform 12 is rotatably connected to the transfer base 11 , a cylinder 15 is rotatably connected to the transfer base 11 , and a piston rod of the cylinder 15 is rotatably connected to the other end of the transfer platform 12 .

[0030] like Figure 1 , Figure 3 , Figure 4 As shown, the active transmission wheel 13 and the driven transmission wheel 14 are rotatably arranged side by side on both sides of the transmission platform 12, and the outer wall of the active transmission wheel 13 is gradually contracted toward the travel direction. The outer wall of the driven transmission wheel 14 is gradually expanded toward the travel direction, so as to automatically push the steel pipe to rotate forward when rotating.

[0031] When the steel pipe needs to be transmitted, the steel pipe is located between the active transmission wheel 13 and the driven transmission wheel 14. At this time, the active transmission wheel 13 rotates, and the driven transmission wheel 14 rotates synchronously with the steel pipe. Since the active transmission wheel 13 and the driven transmission wheel 14 are set with one end larger than the other, and the directions of the large and small ends are opposite, and there is an angle between the entire transmission mechanism 1 and the transmission direction of the steel pipe, during the rotation of the active transmission wheel 13 and the driven transmission wheel 14, the steel pipe can be controlled to rotate and move forward at the same time, thereby realizing stable transmission of the steel pipe.

[0032] Since the transmission platform 12 is rotatably connected to the transmission seat 11, in the actual working process, the cylinder 15 can be used to control the transmission platform 12 to tilt, so as to adjust the angle of the transmission platform 12 to adapt to steel pipes of different thicknesses. The inclination angle of the transmission platform 12 can also adjust the steel pipe transmission rate to meet different transmission requirements.

[0033] like Figure 3 , Figure 5 As shown, the feeding mechanism 2 includes a plurality of feeding racks 21 , which are arranged side by side and extend obliquely downward to the position of the transmission mechanism 1 , and a feeding stop rod 22 is provided at the lowest end of the feeding rack 21 .

[0034] like Figure 3 , Figure 5 As shown, a pair of loading supports 23 located between two adjacent transmission mechanisms 1 are provided on the side of the loading rack 21 close to the transmission mechanism 1 , and a loading plate 24 is rotatably connected to the loading supports 23 .

[0035] like Figure 3 , Figure 5 As shown, the loading plate 24 is arranged in an L shape, and the side for contacting the steel pipe after flipping is arranged to be inclined downward. The loading plate 24 is used to lift the steel pipe on the loading rack 21 after flipping, and make the steel pipe automatically roll down to the top of the transmission mechanism 1.

[0036] When the steel pipes need to be loaded, they are transferred to the loading rack 21 one by one, so that the steel pipes are cross-armed on multiple loading racks 21. At the same time, the steel pipes automatically roll down to the lowest end position of the loading rack 21 and are blocked by the loading stop rod 22 to achieve the positioning of the steel pipes.

[0037] Then, the hydraulic cylinder is used to control the loading plate 24 to rotate. At this time, the loading plate 24 flips from a horizontal state to a vertical state. At the same time, the loading plate 24 lifts up the steel pipe. Since there is an inclined surface on the loading plate 24, the steel pipe will automatically roll down to the lowest end position of the loading plate 24 and be blocked by the bent position. At this time, the steel pipe is located directly above the transmission mechanism 1.

[0038] Then the loading plate 24 is controlled to rotate in the opposite direction. At this time, the loading plate 24 flips from the vertical state to the horizontal state. At the same time, the loading plate 24 gradually lowers the steel pipe, and finally the steel pipe is accurately placed on the transmission mechanism 1, thereby realizing automatic loading of the steel pipe.

[0039] like Figure 6 As shown, the outer wall cleaning mechanism 3 includes a cleaning seat 31, a cleaning pool 32, a cleaning cover 33, a cleaning pipe 34 and a cleaning support 35. The cleaning seat 31 is set on the ground, the cleaning pool 32 is embedded in the cleaning seat 31, and the cleaning cover 33 is buckled on the cleaning seat 31, and the cleaning pool 32 is covered and a steel pipe passes through. One end of the cleaning pipe 34 is connected to the cleaning pool 32, and the other end is located at the top of the cleaning cover 33.

[0040] like Figure 6 As shown, the cleaning support 35 is arranged at the front and rear ends of the cleaning cover 33, and is used to carry and clean the outer wall of the steel pipe respectively.

[0041] like Figure 6 As shown, a flushing seat 36 is arranged at the rear of the cleaning seat 31, and a flushing pool 37 is embedded in the flushing seat 36. A flushing cover 38 for covering the flushing pool 37 is buckled on the flushing seat 36. A flushing pipe 39 is connected to the flushing pool 37, and the flushing pipe 39 is connected to the top of the flushing cover 38.

[0042] When cleaning the outer wall of the steel pipe, the steel pipe enters the cleaning cover 33 and is clamped by the cleaning support 35. At this time, the cleaning pipe 34 sprays the cleaning liquid in the cleaning tank 32 to the outer wall of the steel pipe and cooperates with the work of the cleaning support 35 to clean the outer wall of the steel pipe. At the same time, the cleaning liquid can be recycled and reused to reduce waste.

[0043] Then the steel pipe enters the flushing cover 38, and the flushing pipe 39 sprays the flushing liquid in the flushing tank 37 onto the outer wall of the steel pipe to flush the outer wall of the steel pipe and ensure the cleanliness of the outer wall of the steel pipe. At the same time, the flushing liquid can be recycled and reused to reduce waste.

[0044] like Figure 6 As shown, the cleaning support 35 includes a pair of lower seats 351 , a lower wheel frame 352 , a pair of lower cleaning wheels 353 , an upper seat 354 , an upper wheel frame 355 and an upper cleaning wheel 356 .

[0045] like Figure 6 As shown, a pair of lower seats 351 are distributed on both sides of the cleaning cover 33, a lower wheel frame 352 is set on the lower seat 351 and extends into the cleaning cover 33, a lower cleaning wheel 353 is rotatably connected to the lower wheel frame 352, and is located in the cleaning cover 33 and is used to support the steel pipe.

[0046] like Figure 6As shown, the upper seat 354 is arranged on the cleaning cover 33, the upper wheel frame 355 is arranged on the upper seat 354 and extends into the cleaning cover 33, the upper cleaning wheel 356 is rotatably connected to the upper wheel frame 355, is located in the cleaning cover 33, and is used to compress the steel pipe.

[0047] like Figure 6 As shown, the middle position of the lower wheel frame 352 is rotatably connected to the lower seat 351 , and a guide rod 357 penetrating the wheel frame is provided at the opposite end of the lower seat 351 , and a spring 3571 located above the lower wheel frame 352 is sleeved on the guide rod 357 .

[0048] like Figure 6 As shown, the middle position of the upper wheel frame 355 is rotatably connected to the upper seat 354 , and the cleaning seat 31 is rotatably connected to a hydraulic cylinder 358 , and the piston rod of the hydraulic cylinder 358 is rotatably connected to the end of the upper wheel frame 355 .

[0049] When cleaning the outer wall of the steel pipe, as the steel pipe enters, the steel pipe will press the lower wheel frame 352 and the lower cleaning wheel 353 to move downward, and the lower wheel frame 352 squeezes the spring 3571. When the steel pipe is separated from the lower wheel frame 352, the lower wheel frame 352 and the lower cleaning wheel 353 are automatically flipped to the initial position under the elastic force of the spring 3571, so that the lower wheel frame 352 and the lower cleaning wheel 353 can automatically adapt to steel pipes of different specifications and always press the surface of the steel pipe to achieve stable cleaning.

[0050] At the same time, when the steel pipe enters, the hydraulic cylinder 358 is first used to control the upper wheel frame 355 and the upper cleaning wheel 356 to flip upward. When the steel pipe enters, the upper wheel frame 355 and the upper cleaning wheel 356 are controlled to flip downward, so that the upper cleaning wheel 356 presses the surface of the steel pipe, so that the upper wheel frame 355 and the upper cleaning wheel 356 can automatically adapt to steel pipes of different specifications and always press the surface of the steel pipe to achieve stable cleaning.

[0051] like Figure 6 As shown, a pair of lower seats 351 are slidably connected to the cleaning seat 31, and a screw 359 is horizontally threadedly connected to the cleaning seat 31, and the screw 359 is rotatably connected to the end of the lower seat 351. Therefore, the distance between the pair of lower seats 351 can be controlled according to the diameter specification of the steel pipe and actual needs to meet different work needs.

[0052] like Figure 6 As shown, the material pouring mechanism 5 includes a plurality of material pouring racks 51, which are arranged side by side between the first bearing assembly 41 and the second bearing assembly 42, and one end close to the first bearing assembly 41 is higher than the other end, and a material pouring stop rod 52 is arranged at the lowest end of the material pouring rack 51.

[0053] like Figure 6As shown, both sides of the dumping rack 51 are provided with dumping supports 53, which are respectively located between two adjacent bearing seats 43. A dumping plate 54 is rotatably connected to the dumping support 53, and the dumping plate 54 is L-shaped, and the side for contacting the steel pipe after flipping is tilted downward.

[0054] like Figure 6 As shown, the dumping plate 54 on one side is used to lift up the steel pipe on the first bearing assembly 41 after flipping, and make the steel pipe automatically roll down to the top of the dumping rack 51. The dumping plate 54 on the other side is used to lift up the steel pipe at the lower end of the dumping rack 51 after flipping, and make the steel pipe automatically roll down to the top of the second bearing assembly 42.

[0055] After the steel pipe is transferred to the first bearing assembly 41, the hydraulic cylinder 358 near the first bearing assembly 41 is used to control the pouring plate 54 near the first bearing assembly 41 to rotate, and the pouring plate 54 is flipped from a horizontal state to a vertical state, and the pouring plate 54 lifts the steel pipe. Since the pouring plate 54 is an inclined surface, the steel pipe will automatically roll down to the lowest end of the pouring plate 54 and be blocked by the bent position. At the same time, the steel pipe is located directly above the upper end of the pouring rack 51.

[0056] Then the pouring plate 54 is controlled to rotate in the opposite direction. At this time, the pouring plate 54 flips from the vertical state to the horizontal state. At the same time, the pouring plate 54 gradually lowers the steel pipe, and finally the steel pipe is accurately placed at the upper end position of the pouring rack 51. Then the steel pipe rolls from top to bottom along the pouring rack 51. When the steel pipe automatically rolls to the lowest end position of the pouring rack 51, it is blocked by the pouring stop rod 52 to achieve the positioning of the steel pipe.

[0057] Then, the hydraulic cylinder near the second bearing assembly 42 is used to control the pouring plate 54 near the second bearing assembly 42 to rotate, and the pouring plate 54 is flipped from a horizontal state to a vertical state, and the pouring plate 54 lifts up the steel pipe. Since the pouring plate 54 is an inclined surface, the steel pipe will automatically roll down to the lowest end of the pouring plate 54 and be blocked by the bent position. At the same time, the steel pipe is located directly above the upper end of the second bearing assembly 42.

[0058] Then the pouring plate 54 is controlled to rotate in the opposite direction, and the pouring plate 54 is flipped from the vertical state to the horizontal state. At the same time, the pouring plate 54 gradually lowers the steel pipe, and finally the steel pipe is accurately placed on the second supporting component 42, realizing automatic pouring of the steel pipe.

[0059] like Figure 7As shown, the inner wall brushing mechanism 6 includes a brushing seat 61, a brushing pipe 62, a brushing head 63, a traveling vehicle 64 and a sewage pool 65. The brushing seat 61 is distributed at both ends of the second bearing assembly 42, and the brushing pipe 62 slides horizontally on the brushing seat 61 and is used to be inserted into both ends of the steel pipe. The brushing head 63 is arranged at the end position of the brushing pipe 62 and is used to press against the inner wall of the steel pipe.

[0060] like Figure 7 As shown, the traveling vehicle 64 is slidably connected to the scrubbing seat 61 and is used to control the horizontal sliding of the scrubbing pipe 62. The cleaning pool 32 is located between the scrubbing seat 61 and the second bearing assembly 42 and below the pipe opening of the steel pipe.

[0061] When the inner wall of the steel pipe needs to be cleaned, the traveling vehicle 64 is used to control the synchronous sliding of the brush pipe 62 and the brush head 63, and the end position of the brush pipe 62 is inserted into the steel pipe. At the same time, the second supporting component 42 is used to control the rotation of the steel pipe position, and the traveling vehicle 64 is used to control the brush pipe 62 and the brush head 63 to move slowly.

[0062] At this time, the cleaning liquid will flow into the steel pipe along the scrubbing pipe 62, and the inner wall of the steel pipe will be scrubbed with the scrubbing head 63. The combination of scrubbing and flushing can ensure the cleaning effect of the inner wall of the steel pipe and improve the cleanliness of the inner wall of the steel pipe. Finally, the sewage will be collected in the sewage pool 65 to achieve stable recycling of sewage. After recycling, an oil-water separation mechanism can be added in the sewage pool 65 to achieve the reuse of the cleaning liquid.

[0063] Since the brush pipes 62 are inserted into both ends of the steel pipe at the same time, when the inner wall is cleaned, when both brush pipes 62 move to the middle position of the steel pipe, one of the brush pipes 62 retreats and the other continues to slide forward, thereby ensuring all-round cleaning of the inner wall of the steel pipe.

[0064] like Figure 8 As shown, the unloading mechanism 7 includes a transport track 71, a transport roller 72 and a unloading support 73. The transport track 71 is horizontally arranged beside the second bearing assembly 42, and the transport roller 72 is horizontally rotatably connected to the transport track 71. Both ends of the transport roller 72 are provided with limit rods 74 for clamping the steel pipe.

[0065] like Figure 8 As shown, the unloading support 73 is respectively located between two adjacent bearing seats 43, and a unloading plate 75 is rotatably connected to the unloading support 73. The unloading plate 75 is set in an L shape, and the side used for contacting the steel pipe after flipping is set to be inclined downward. The unloading plate 75 is used to lift the steel pipe on the second bearing assembly 42 after flipping, and make the steel pipe automatically roll down to the top of the transport roller 72.

[0066] When the cleaned steel pipe needs to be unloaded, the hydraulic cylinder is used to control the unloading plate 75 to rotate, and the unloading plate 75 is flipped from a horizontal state to a vertical state, and the unloading plate 75 lifts up the steel pipe. Since the unloading plate 75 is an inclined surface, the steel pipe will automatically roll down to the lowest end of the unloading plate 75 and be blocked by the bent position. At the same time, the steel pipe is located directly above the transport roller 72.

[0067] Then, the unloading plate 75 is controlled to rotate in the opposite direction, and the unloading plate 75 is flipped from the vertical state to the horizontal state. At the same time, the unloading plate 75 gradually lowers the steel pipe, and finally the steel pipe is accurately placed on the transport roller 72 and located between the limit rods 74 at both ends of the transport roller 72. Finally, the transport roller 72 is controlled to rotate, and the cleaned steel pipe can be transported to complete the next step or process.
