Description
Technical Field
[0001] This invention relates to the field of coating technology, specifically to a device for coating the inner wall of a cable protection pipe with an anti-corrosion layer. Background Technology
[0002] As is well known, the cable protection pipe reinforced inner wall anti-corrosion coating device is a special equipment used to coat the inner wall of the cable protection pipe with an anti-corrosion layer. It uses a specific mechanism to evenly coat the anti-corrosion coating onto the inner wall of the pipe, forming a protective layer with anti-corrosion and wear-resistant properties, thereby extending the service life of the cable protection pipe and ensuring the safe operation of the cable. This device usually integrates functions such as feeding, coating, and curing, and can be adapted to protection pipes of different diameters. Through automated operation, it achieves efficient and stable inner wall anti-corrosion coating and is widely used in the cable protection pipe processing of power, communication and other fields.
[0003] A search revealed a Chinese patent disclosure for a surface coating device for processing polypropylene cable protection pipes, application publication number CN116510943B. This patent uses a drive guide rod to move an inner wall support plate to support the inner wall of the polypropylene cable protection pipe. Then, the drive motor is turned on to allow the polypropylene cable protection pipe to move. Finally, a support cylinder at one end drives a fixing clamp to retract into the protective housing, while the other end fixes and clamps the support rod. This allows the polypropylene cable protection pipe to move to the inside of the protective housing for coating from one side. Simultaneously, the fixing clamp at one end re-clamps the support rod, while the fixing clamp at the other end retracts into the protective housing, allowing the coated polypropylene cable protection pipe to move out from the other end of the protective housing. This design achieves bidirectional transport of the polypropylene cable protection pipe by contacting its inner wall, thus avoiding the risk of wiping off the coating and improving the working efficiency of the coating device.
[0004] When spraying anti-corrosion coatings onto the inner walls of large cable protection pipes, a spraying structure is used to gradually spray the coating onto the inner walls of the pipe. The problem with existing technology is that when spraying anti-corrosion coatings onto cable protection pipes of different diameters, the lack of an integrated support and displacement structure that adapts to different pipe diameters makes it impossible to provide support and displacement, thus reducing the flexibility of spraying anti-corrosion coatings onto the inner walls of cable protection pipes with different pipe diameters. Summary of the Invention
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this invention provides a device for coating the inner wall of cable protection pipes with an anti-corrosion layer. This device features an integrated support and displacement structure that adapts to inner walls of different pipe diameters. Therefore, it can adapt to inner walls of different pipe diameters, provide support and displacement, and spray an anti-corrosion coating, thus improving the flexibility of spraying anti-corrosion coatings on the inner walls of cable protection pipes with different pipe diameters.
[0007] (II) Technical Solution
[0008] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a coating device for the inner wall anti-corrosion layer of cable protection pipe reinforcement, comprising a moving mechanism and a coating mechanism. The moving mechanism includes a limiting component, a telescopic component, an adjusting component, an adapting component, and a displacement component. The telescopic component is located on top of the limiting component. Two adjusting components are respectively located on the front side of the limiting component and the rear side of the telescopic component. The adapting component is located inside the adjusting component. The displacement component is located on the side of the adapting component away from the limiting component. The coating mechanism includes a transfer component, a feeding component, a distributing component, and a spraying component. The transfer component is located on the front side of the adjusting component. The feeding component is located on the side of the transfer component away from the limiting component. The distributing component is located on the side of the feeding component away from the transfer component. The spraying component is located on the side of the distributing component away from the feeding component.
[0009] By adopting the above technical solution, by setting up a moving mechanism and a coating mechanism, the moving mechanism can adapt to the diameter of the inner wall of the cable protection pipe and drive the coating mechanism to move along the cable protection pipe. The coating mechanism can uniformly coat the inner wall of the cable protection pipe with an anti-corrosion coating as the moving mechanism moves.
[0010] The present invention is further configured such that: the limiting component includes a limiting track plate, a positioning motor base and a first servo motor, the positioning motor base is bolted to the front side of the limiting track plate, the first servo motor is snapped to the inner side of the positioning motor base, and the output shaft of the rear side of the first servo motor passes through the rear side of the positioning motor base and is rotatably connected to the positioning motor base.
[0011] By adopting the above technical solution, a limiting component is set up. The limiting track plate provides a guide for the forward and backward movement of the screw hole extension plate. The positioning motor base is a support structure that limits the first servo motor and the second servo motor. The first servo motor is a transmission structure that provides axial rotation for the adjusting screw. The limiting track plate can be used in conjunction with the positioning motor base and the first servo motor, allowing the first servo motor to provide axial rotation for the adjusting screw with the positioning motor base as the support point, and allowing the screw hole extension plate to move forward and backward within the limiting track plate.
[0012] The present invention is further configured such that: the telescopic assembly includes an adjusting screw, a screw hole extension plate, and a limit motor base; the adjusting screw is fixedly connected to the output end of the rear side of the first servo motor; the screw hole extension plate is threadedly connected to the surface of the adjusting screw; the two sides of the screw hole extension plate are slidably connected to the inner side of the limit track plate; and the limit motor base is bolted to the rear side of the top of the screw hole extension plate.
[0013] By adopting the above technical solution, and by setting up a telescopic component, the adjusting screw allows the threaded extension plate to move on its surface, achieving the effect of moving the threaded extension plate back and forth. The threaded extension plate can provide support for the limit motor base, and when it moves with the adjusting screw, it drives the limit motor base to move together. The limit motor base is a support structure that provides a limit for the second servo motor, and it can drive the second servo motor to move together with the threaded extension plate. By using the adjusting screw in conjunction with the threaded extension plate and the limit motor base, when the adjusting screw rotates axially in different directions, the threaded movement can be used to allow the threaded extension plate to move back and forth when it is limited by the limit track plate on the surface of the adjusting screw, thereby driving the limit motor base to adjust the orientation of the second servo motor, so as to further change the spacing between the positioning discs.
[0014] The invention is further configured such that: the adjustment assembly includes a second servo motor, a positioning disk, a positioning T-shaped slide plate, a transmission disk, and a vortex plate; two second servo motors are respectively snapped onto the top of the inner side of the positioning motor base and the top of the inner side of the limiting motor base; the positioning disk is fixedly connected to the side of the second servo motor away from the limiting track plate; the output end of the side of the second servo motor away from the limiting track plate passes through the positioning disk and is rotatably connected to the positioning disk; four positioning T-shaped slide plates are respectively fixedly connected to the two sides, top, and bottom of the side of the positioning disk away from the limiting track plate; the transmission disk is fixedly connected to the output end of the side of the second servo motor away from the limiting track plate; and the vortex plate is welded to the side of the transmission disk near the positioning disk.
[0015] Using the above technical solution, by setting up adjustment components, the two second servo motors use the positioning motor base and the limit motor base as support points respectively, and each provides support for the corresponding positioning disk. The positioning disk can provide support and limit for the positioning T-shaped slide plate. The positioning T-shaped slide plate is a structure that guides the movement of the adaptive slide plate. The transmission disk is a structure that rotates with the axial rotation of the output shaft of the second servo motor, and can provide the power required for the rotation of the vortex plate. The vortex plate is a vortex-shaped transmission plate structure, which can use its own vortex-shaped structure to provide thrust for the adjustment vortex groove, so that the adaptive slide plate moves with the adjustment vortex groove on the vortex plate. As the rotation direction of the vortex plate is different, the centripetal movement and centrifugal movement of the adaptive slide plate are realized.
[0016] The invention is further configured such that: the adaptation component includes an adaptation slide plate, a positioning slide groove, and an adjustment vortex groove; four adaptation slide plates are respectively located on both sides, the top, and the bottom of the positioning disk on the side away from the limiting track plate; the positioning slide groove is opened on the side of the adaptation slide plate close to the positioning disk; the inner side of the positioning slide groove is slidably connected to the surface of the positioning T-shaped slide plate; the adjustment vortex groove is opened on the side of the adaptation slide plate away from the positioning slide groove; the inner side of the adjustment vortex groove is slidably connected to the side of the vortex plate close to the positioning disk.
[0017] By adopting the above technical solution, and by setting up an adaptation component, the adaptation slide plate consists of four slide plate structures that can provide support for the wheel base. The positioning slide groove is a T-shaped guide groove structure, and the adjustment vortex groove is a multi-semi-circular guide groove structure. Through the cooperation of the adaptation slide plate with the positioning slide groove and the adjustment vortex groove, the adaptation slide plate can slide centripetally and centrifugally on the surface of the positioning T-shaped slide plate through the positioning slide groove. The adjustment vortex groove can move centripetally and centrifugally together with the adaptation slide plate through contact with the vortex plate and the rotation of the vortex plate. With the displacement generated by the rotation of the vortex plate, the adjustment vortex groove can drive the adaptation slide plate to move centripetally and centrifugally together. Ultimately, the adaptation slide plate can drive the wheel base to adapt to the orientation of the inner wall of the cable protection pipe.
[0018] The invention is further configured such that: the displacement assembly includes a wheel base, a wheel servo motor, and a Mecanum wheel; the wheel base is bolted to the side of the adaptable slide away from the transmission disc; the wheel servo motor is bolted to the side of the wheel base near the limiting track plate; and the Mecanum wheel is fixedly connected to the output shaft of the wheel servo motor near the limiting track plate.
[0019] By adopting the above technical solution, and by setting a displacement component, the wheel base provides a limiting support structure for the wheel servo motor. As the adaptive slide moves, it drives the wheel servo motor to adjust the orientation of the Mecanum wheel. The wheel servo motor is a transmission structure that provides axial rotation for the Mecanum wheel, providing the power required for the Mecanum wheel to rotate. The Mecanum wheel is an omnidirectional wheel in the prior art. Through the cooperation of the wheel base, the wheel servo motor, and the Mecanum wheel, the wheel servo motor can move omnidirectionally within the cable protection pipe in cooperation with other Mecanum wheels, depending on the different speeds and directions provided by the wheel servo motor, as the wheel base moves with the adaptive slide to the inner wall of the cable protection pipe, supported and limited by the wheel base.
[0020] The present invention is further configured such that: the transfer component includes a positioning box, a limiting sleeve, and a dispensing box; the dispensing box is bolted to the front side of the positioning plate; the limiting sleeve is rotatably connected to the front side of the inner side of the dispensing box; and the positioning box is welded to the front side of the limiting sleeve.
[0021] By adopting the above technical solution, and by setting up a transfer component, the positioning box is a corrosion-resistant coating material conveying structure that limits the pump, and the limiting sleeve is a limiting structure connected to the distributing box. The distributing box can be used as a support point to limit the positioning box. The distributing box is a corrosion-resistant coating material conveying structure that can provide corrosion-resistant coating to the distributing corrugated pipe. By using the positioning box, the limiting sleeve and the distributing box in conjunction, the positioning box can convey the corrosion-resistant coating material into the distributing box. When the distributing box rotates with the positioning plate, the limiting sleeve and the distributing box limit the positioning box, allowing the distributing box to rotate along with the positioning plate along the limiting sleeve, and preventing the positioning box and the limiting sleeve from rotating together with the distributing box.
[0022] The present invention is further configured such that: the feeding assembly includes a pump, a feeding bellows, and a feed inlet; the pump is bolted to the front side of the positioning box; the input end of the pump is connected to the positioning box; the feeding bellows is connected to the output end of the pump; and the feed inlet is located on the front side of the feeding bellows.
[0023] By adopting the above technical solution, a feeding assembly is set up. The pump is a fluid pumping structure, the feeding bellows is a corrosion-resistant coating material conveying structure, and the inlet is a corrosion-resistant coating material introduction structure. The pump, feeding bellows, and inlet are used in conjunction. When it is necessary to provide corrosion-resistant coating material to the positioning box, the inlet on the feeding bellows is connected to an external corrosion-resistant coating material conveying device. When the corrosion-resistant coating material is conveyed by the corrosion-resistant coating material conveying device, it is transported to the pump through the feeding bellows. After secondary pressurization by the pump, the corrosion-resistant coating material can be provided to the positioning box.
[0024] The present invention is further configured such that: the material distribution assembly includes a material distribution corrugated pipe, a feeding pump and a material pump base, the four material distribution corrugated pipes are respectively connected to the two sides, the top and the bottom of the material distribution box, the feeding pump is connected to the side of the material distribution corrugated pipe away from the material distribution box, the material pump base is fixedly connected to the surface of the feeding pump, and the rear side of the material pump base is bolted to the front side of the transmission disc.
[0025] By adopting the above technical solution, a material distribution component is set up. The material distribution corrugated pipe is a separate conveying structure for the anti-corrosion coating material, which can convey the anti-corrosion coating material separately in four directions. The feeding pump is a secondary pressurization conveying structure for the anti-corrosion coating material. The material pump base is a support structure that limits the feeding pump. Through the cooperation of the material distribution corrugated pipe, the feeding pump and the material pump base, the material pump base can limit the feeding pump to the side that adapts to the slide plate away from the second servo motor. When the material distribution corrugated pipe conveys the anti-corrosion coating material to the feeding pump, the feeding pump further pressurizes the anti-corrosion coating material and provides the pressurized anti-corrosion coating material to the feeding pipe.
[0026] The present invention is further configured such that: the spraying assembly includes a feeding pipe, a paint nozzle, and a pipe cap; the feeding pipe is threadedly connected to the side of the material pump base away from the material distribution box; the side of the feeding pipe near the material distribution box is connected to the output end of the material pump; the paint nozzle is connected to the side of the feeding pipe away from the material distribution box; and the pipe cap is threadedly connected to the front side of the feeding pipe.
[0027] By adopting the above technical solution, a spraying assembly is set up. The feeding pipe is a guide structure for the anti-corrosion coating material, which guides the anti-corrosion coating material to the paint nozzle. The paint nozzle is a spraying structure for the anti-corrosion coating material, which sprays the anti-corrosion coating material onto the inner wall of the cable protection pipe. The pipe cap is a structure that seals the feeding pipe and has a built-in rubber sealing ring. The rubber sealing ring is in close contact with the feeding pipe, allowing the front of the feeding pipe to be sealed when no maintenance of the paint nozzle is required. Through the cooperation of the feeding pipe, paint nozzle, and pipe cap, the feeding pipe can evenly deliver the anti-corrosion coating material to the input end of each paint nozzle. Then, the pressure continuously provided by the feeding pump allows the paint nozzle to spray the anti-corrosion coating material onto the inner wall of the cable protection pipe. The pipe cap can seal the feeding pipe when no maintenance of the paint nozzle is required. When maintenance of the paint nozzle is required, the paint nozzle can be disassembled and maintained from the feeding pipe by opening the pipe cap.
[0028] (III) Beneficial Effects
[0029] Compared with the prior art, the present invention provides a coating device for the inner wall anti-corrosion layer of cable protection pipe reinforcement, which has the following beneficial effects:
[0030] This device for coating the inner wall of cable protection pipes with an anti-corrosion layer, through the setting of a moving mechanism, allows the limiting component to be used in conjunction with the telescopic component, adjusting component, adapting component, and displacement component. When adapting to the diameter of the cable protection pipe, the second servo motor, using the limiting motor base and the positioning motor base as support points, drives the transmission disc to rotate the vortex plate. The vortex plate then drives the adjusting vortex groove to move the adapting slide plate along the positioning slide groove on the positioning T-shaped slide plate in a centripetal or centrifugal motion until the wheel servo motor, along with the movement of the wheel base and the adapting slide plate, contacts the inner wall of the cable protection pipe, and the contact is achieved through the Mecanum wheel. To provide support for the slide plate, vortex plate, and transmission plate, the transmission plate can provide support and limit for the second servo motor, positioning motor base, limit motor base, and positioning box. The first servo motor drives the adjusting screw to rotate with the positioning motor base as the support point. The screw hole extension plate is adjusted in front and behind through the threaded transmission. The screw hole extension plate drives the limit motor base to adjust the distance between the limit motor base and the positioning motor base. This allows for further adjustment of the distance between the second servo motors, thereby further adapting to the length of the cable protection pipe and improving the stability of the subsequent coating mechanism when spraying the anti-corrosion coating on the inner wall of the cable protection pipe.
[0031] This device for coating the inner wall of cable protection pipes with an anti-corrosion layer includes a coating mechanism. The transfer component can cooperate with a feeding component, a distributing component, and a spraying component. When an anti-corrosion coating needs to be sprayed onto the inner wall of the cable protection pipe, the anti-corrosion coating material is fed through the feeding bellows to the extraction pump via the inlet. The extraction pump further pressurizes the anti-corrosion coating material and delivers it to the positioning box, then to the distributing box. The distributing box evenly distributes the anti-corrosion coating material into each distributing bellows. The flexible tube can adapt to the movement of the slide plate and the material pump base, and can deliver the anti-corrosion coating material to the feed pump. The feed pump can pressurize the anti-corrosion coating material a second time and deliver it to the feed tube, providing the anti-corrosion coating material required for the paint nozzles. The feed pump can evenly deliver the anti-corrosion coating material to each paint nozzle, allowing the paint nozzles to spray the pressurized anti-corrosion coating material into the cable protection tube. Furthermore, as the Mecanum wheel moves within the cable protection tube, spraying is also achieved simultaneously with the movement, improving the flexibility of spraying anti-corrosion coatings inside the cable protection tube.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0046] Example 1
[0047] Please see Figure 1-7A device for coating the inner wall of a cable protection pipe with an anti-corrosion layer includes a moving mechanism 1. The moving mechanism 1 includes a limiting component 11, a telescopic component 12, an adjusting component 13, an adapting component 14, and a displacement component 15. The telescopic component 12 is located on top of the limiting component 11. The two adjusting components 13 are respectively located in front of the limiting component 11 and behind the telescopic component 12. The adapting component 14 is located inside the adjusting component 13. The displacement component 15 is located on the side of the adapting component 14 away from the limiting component 11. By setting the moving mechanism 1, the limiting component 11 can be used in conjunction with the telescopic component 12, the adjusting component 13, the adapting component 14, and the displacement component 15. When adapting to the diameter of the cable protection pipe, the second servo motor 131 drives the transmission disk 134 to rotate the vortex plate 135 with the limiting motor base 123 and the positioning motor base 112 as support points. The vortex plate 135 will then drive the adjusting vortex groove 143 to move the adapting slide plate 141 along the positioning slide groove 142 on the positioning T-shaped slide plate 133. The wheel servo motor 152 moves centripetally or centrifugally until it contacts the inner wall of the cable protection tube as the wheel base 151 and the adapting slide plate 141 move. It also contacts the inner wall of the cable protection tube through the Mecanum wheel 153, providing support for the adapting slide plate 141, the vortex plate 135 and the transmission disk 134. Thus, the transmission disk 134 can provide support and limit for the second servo motor 131, the positioning motor base 112, the limit motor base 123 and the positioning box 211. The first servo motor 113 drives the adjusting screw 121 to rotate with the positioning motor base 112 as the support point. The screw hole extension plate 122 is adjusted in front and behind through the thread transmission. The screw hole extension plate 122 drives the limit motor base 123 to adjust the distance between the limit motor base 123 and the positioning motor base 112. This can further adjust the distance between the second servo motors 131, thereby further adapting to the length of the cable protection tube and improving the stability of the subsequent coating mechanism 2 when spraying the anti-corrosion coating on the inner wall of the cable protection tube.
[0048] The limiting component 11 includes a limiting track plate 111, a positioning motor base 112, and a first servo motor 113. The positioning motor base 112 is bolted to the front side of the limiting track plate 111, and the first servo motor 113 is snapped into the inner side of the positioning motor base 112. The output shaft of the rear side of the first servo motor 113 passes through the rear side of the positioning motor base 112 and is rotatably connected to the positioning motor base 112. By setting the limiting component 11, the limiting track plate 111 provides a guide for the forward and backward movement of the screw hole extension plate 122. The positioning motor base 112 is a support structure that limits the first servo motor 113 and the second servo motor 131. The first servo motor 113 is a transmission structure that provides axial rotation for the adjusting screw 121. The limiting track plate 111 can be used in conjunction with the positioning motor base 112 and the first servo motor 113, so that the first servo motor 113 can provide axial rotation for the adjusting screw 121 with the positioning motor base 112 as the support point, and the screw hole extension plate 122 can move back and forth within the limiting track plate 111.
[0049] The telescopic assembly 12 includes an adjusting screw 121, a screw hole extension plate 122, and a limit motor base 123. The adjusting screw 121 is fixedly connected to the output end of the first servo motor 113. The screw hole extension plate 122 is threadedly connected to the surface of the adjusting screw 121. The two sides of the screw hole extension plate 122 are slidably connected to the inner side of the limit track plate 111. The limit motor base 123 is bolted to the rear side of the top of the screw hole extension plate 122. By setting the telescopic assembly 12, the adjusting screw 121 can cause the screw hole extension plate 122 to move threadedly on its surface, achieving the effect of moving the screw hole extension plate 122 back and forth. The screw hole extension plate 122 can provide support for the limit motor base 123 and move with the adjusting screw 121. When the lead screw 121 moves, it drives the limit motor base 123 to move together. The limit motor base 123 is a support structure that provides a limit for the second servo motor 131. It can drive the second servo motor 131 to move together with the screw hole extension plate 122 as the screw hole extension plate 122 moves. By adjusting the lead screw 121 in conjunction with the screw hole extension plate 122 and the limit motor base 123, when the lead screw 121 rotates axially in different directions, the screw hole extension plate 122 can be moved back and forth by the screw thread when the surface of the lead screw 121 is limited by the limit track plate 111. This drives the limit motor base 123 to adjust the position of the second servo motor 131, so as to further change the spacing between the positioning disks 132.
[0050] The adjustment assembly 13 includes a second servo motor 131, a positioning disk 132, a positioning T-shaped slide plate 133, a transmission disk 134, and a vortex plate 135. Two second servo motors 131 are respectively snapped onto the top of the inner side of the positioning motor base 112 and the top of the inner side of the limiting motor base 123. The positioning disk 132 is fixedly connected to the side of the second servo motor 131 away from the limiting track plate 111. The output end of the second servo motor 131 on the side away from the limiting track plate 111 passes through the positioning disk 132 and is rotatably connected to it. Four positioning T-shaped slide plates 133 are respectively fixedly connected to the two sides, top, and bottom of the side of the positioning disk 132 away from the limiting track plate 111. The transmission disk 134 is fixedly connected to the output end of the second servo motor 131 on the side away from the limiting track plate 111. The vortex plate 135 is welded to the transmission disk 134 near the positioning disk 132. On one side, by setting the adjustment component 13, two second servo motors 131 respectively use the positioning motor base 112 and the limit motor base 123 as support points, and each provides support for the corresponding positioning disk 132. The positioning disk 132 can provide support and limit for the positioning T-shaped slide plate 133. The positioning T-shaped slide plate 133 is a structure that guides the movement of the adaptation slide plate 141. The transmission disk 134 is a structure that rotates with the axial rotation of the output shaft of the second servo motor 131, and can provide the power required for the rotation of the vortex plate 135. The vortex plate 135 is a vortex-shaped transmission plate structure, which can use its own vortex-shaped structure to provide thrust for the adjustment vortex groove 143, so that the adaptation slide plate 141 moves on the vortex plate 135 with the adjustment vortex groove 143. As the rotation direction of the vortex plate 135 is different, the centripetal movement and centrifugal movement of the adaptation slide plate 141 can be realized.
[0051] The adaptation component 14 includes four adaptation slides 141, positioning grooves 142, and adjusting vortex grooves 143. The four adaptation slides 141 are respectively located on both sides, top, and bottom of the positioning disk 132 away from the limiting track plate 111. The positioning grooves 142 are located on the side of the adaptation slides 141 closest to the positioning disk 132, and their inner sides are slidably connected to the surface of the positioning T-shaped slide 133. The adjusting vortex grooves 143 are located on the side of the adaptation slides 141 away from the positioning grooves 142, and their inner sides are slidably connected to the side of the vortex plate 135 closest to the positioning disk 132. By setting the adaptation component 14, the adaptation slides 141 form a four-slide structure, which can accommodate vehicles... The wheel base 151 provides support, the positioning slide 142 is a T-shaped guide groove structure, and the adjusting vortex groove 143 is a multi-semi-circular guide groove structure. The adapting slide 141 is used in conjunction with the positioning slide 142 and the adjusting vortex groove 143. The adapting slide 141 can slide centripetally and centrifugally on the surface of the positioning T-shaped slide 133 through the positioning slide 142. The adjusting vortex groove 143 can move centripetally and centrifugally together with the adapting slide 141 through contact with the vortex plate 135 and the rotation of the vortex plate 135. With the displacement generated when the vortex plate 135 rotates, the adapting slide 141 is driven to move centripetally and centrifugally together, so that the adapting slide 141 can drive the wheel base 151 to adapt to the orientation of the inner wall of the cable protection pipe.
[0052] The displacement assembly 15 includes a wheel base 151, a wheel servo motor 152, and a Mecanum wheel 153. The wheel base 151 is bolted to the side of the adapting slide plate 141 away from the transmission disk 134. The wheel servo motor 152 is bolted to the side of the wheel base 151 near the limiting track plate 111. The Mecanum wheel 153 is fixedly connected to the output shaft of the wheel servo motor 152 near the limiting track plate 111. By setting the displacement assembly 15, the wheel base 151 provides a limiting support structure for the wheel servo motor 152. As the adapting slide plate 141 moves, it drives the wheel servo motor 152 to move the Mecanum wheel 153. Position adjustment: The wheel servo motor 152 is a transmission structure that provides axial rotation for the Mecanum wheel 153. It can provide the power required for the rotation of the Mecanum wheel 153. The Mecanum wheel 153 is an omnidirectional wheel in the prior art. It is used in conjunction with the wheel servo motor 152 and the Mecanum wheel 153 through the wheel base 151. The wheel servo motor 152 can move omnidirectionally in conjunction with other Mecanum wheels 153 in the inner wall of the cable protection pipe when the wheel base 151 moves to the inner wall of the cable protection pipe with the adaptation slide plate 141, depending on the different speed and direction provided by the wheel servo motor 152.
[0053] The working principle of this embodiment is as follows: First, the first servo motor 113, the second servo motor 131, and the wheel servo motor 152 are connected to an external mobile battery and a signal receiver via wires. The signal receiver is then remotely connected to a PLC controller. The PLC controller then uses its built-in preset program to control the first servo motor 113, the second servo motor 131, and the wheel servo motor 152. When the Mecanum wheel 153 needs to adapt to the inner wall of the current cable protection pipe diameter, the second servo motor 131 uses the limit motor base 123 and the positioning motor base 112 as support points. It rotates the output shaft counterclockwise to rotate the transmission disk 134. The transmission disk 134 rotates the vortex plate 135. As the vortex plate 135 rotates counterclockwise, it drives the adjusting vortex groove 143 to move the adapting slide plate 141 in a centrifugal direction. The adapting slide plate 141 then moves along the positioning T-shaped slide plate 133 on the positioning disk 132 towards the inner wall of the cable protection pipe via the positioning groove 142. The process continues until the adaptive sliding plate 141 moves the wheel base 151 to the inner wall of the cable protection pipe, then the first servo motor 113 drives the adjusting screw 121 to rotate counterclockwise. The adjusting screw 121 then moves the screw hole extension plate 122 towards the positioning motor base 112. The screw hole extension plate 122 then drives the limit motor base 123 to move the second servo motor 131, which is far away from the positioning motor base 112, towards the second servo motor 131 at the positioning motor base 112, reducing the distance between the two second servo motors 131 and thus increasing the balance between the two second servo motors 131. Finally, the wheel servo motor 152, with the wheel base 151 as the support point, drives the Mecanum wheel 153 to rotate adaptively under the control of the PLC. The Mecanum wheel 153 then moves along the inner wall of the cable protection pipe, moving the entire structure of the moving mechanism 1 and the entire structure of the coating mechanism 2 together, until they reach the designated destination according to the preset program.
[0054] Example 2
[0055] refer to Figure 8-12A coating device for reinforcing the inner wall of a cable protection pipe with an anti-corrosion coating also includes a coating mechanism 2. The coating mechanism 2 includes a transfer component 21, a feeding component 22, a distributing component 23, and a spraying component 24. The transfer component 21 is located in front of the adjusting component 13. The feeding component 22 is located on the side of the transfer component 21 away from the limiting component 11. The distributing component 23 is located on the side of the feeding component 22 away from the transfer component 21. The spraying component 24 is located on the side of the distributing component 23 away from the feeding component 22. By setting the coating mechanism 2, the transfer component 21 can cooperate with the feeding component 22, the distributing component 23, and the spraying component 24. When it is necessary to spray an anti-corrosion coating onto the inner wall of the cable protection pipe, with the anti-corrosion coating material conveying structure connected to the external feeding corrugated pipe 222, the anti-corrosion coating material is conveyed through the inlet 223 to the pump 221 via the feeding corrugated pipe 222. The pump 221 can then pump the anti-corrosion coating material into the feed pipe. After initial pressurization, the material is conveyed to the positioning box 211, and then from the positioning box 211 to the distribution box 213. The distribution box 213 can evenly convey the anti-corrosion coating material to each distribution corrugated pipe 231. The distribution corrugated pipe 231 can adapt to the movement of the material pump base 233 driven by the slide plate 141 through its own flexible structure, and can also convey the anti-corrosion coating material to the feeding pump 232. The feeding pump 232 can pressurize the anti-corrosion coating material a second time and then convey it to the feeding pipe 241 to provide the anti-corrosion coating material required for spraying the paint nozzle 242. The feeding pump 232 can evenly convey the anti-corrosion coating material to each paint nozzle 242, allowing the paint nozzle 242 to spray the pressurized anti-corrosion coating material into the cable protection pipe. As the Mecanum wheel 153 moves within the cable protection pipe, the spraying is also achieved simultaneously with the movement, improving the flexibility of spraying the anti-corrosion coating inside the cable protection pipe.
[0056] The transfer component 21 includes a positioning box 211, a limiting sleeve 212, and a dispensing box 213. The dispensing box 213 is bolted to the front of the positioning plate 132, and the limiting sleeve 212 is rotatably connected to the front of the inner side of the dispensing box 213. The positioning box 211 is welded to the front of the limiting sleeve 212. By setting the transfer component 21, the positioning box 211 serves as a corrosion-resistant coating material conveying structure that limits the feeding pump 221, and the limiting sleeve 212 serves as a limiting structure connected to the dispensing box 213. The dispensing box 213 can be used as a support point to limit the positioning box 211. For the anti-corrosion coating material conveying structure, anti-corrosion coating can be provided to the material distribution corrugated pipe 231. The positioning box 211, the limiting sleeve 212, and the material distribution box 213 are used together. The positioning box 211 can convey the anti-corrosion coating material into the material distribution box 213. When the material distribution box 213 rotates with the positioning plate 132, the limiting sleeve 212 and the material distribution box 213 limit the positioning box 211, so that the material distribution box 213 can rotate along the limiting sleeve 212 with the positioning plate 132, and prevent the positioning box 211 and the limiting sleeve 212 from rotating together with the material distribution box 213.
[0057] The feeding assembly 22 includes a pump 221, a bellows 222, and an inlet 223. The pump 221 is bolted to the front of the positioning box 211, and its rear input end is connected to the positioning box 211. The bellows 222 is connected to the output end of the pump 221, and the inlet 223 is located at the front of the bellows 222. By configuring the feeding assembly 22, the pump 221 serves as a fluid pumping structure, and the bellows 222 serves as a corrosion-resistant coating material conveying structure. The material inlet 223 is a structure for introducing anti-corrosion coating material. It is used in conjunction with the material pump 221, the feeding bellows 222 and the material inlet 223. When it is necessary to provide anti-corrosion coating material to the positioning box 211, the material inlet 223 on the feeding bellows 222 is connected to an external anti-corrosion coating material conveying device. When the anti-corrosion coating material is conveyed by the anti-corrosion coating material conveying device, it is transported to the material pump 221 through the feeding bellows 222. After secondary pressurization by the material pump 221, the anti-corrosion coating material can be provided to the positioning box 211.
[0058] The material distribution assembly 23 includes four corrugated pipes 231, a feeding pump 232, and a pump base 233. The four corrugated pipes 231 are respectively connected to the two sides, top, and bottom of the material distribution box 213. The feeding pump 232 is connected to the side of the corrugated pipes 231 away from the material distribution box 213. The pump base 233 is fixedly connected to the surface of the feeding pump 232, and the rear side of the pump base 233 is bolted to the front side of the transmission disc 134. By setting the material distribution assembly 23, the corrugated pipes 231 form a structure for separating and conveying anti-corrosion coated material, which can distribute the anti-corrosion coated material to four... The material is conveyed separately in a specific direction. The feeding pump 232 is a secondary pressurized conveying structure for the anti-corrosion coating material. The pump base 233 is a support structure that limits the feeding pump 232. The material distribution corrugated pipe 231 cooperates with the feeding pump 232 and the pump base 233. The pump base 233 can limit the feeding pump 232 to the side of the adaptable slide plate 141 away from the second servo motor 131. When the anti-corrosion coating material is conveyed to the feeding pump 232 by the distribution corrugated pipe 231, the feeding pump 232 further pressurizes the anti-corrosion coating material and provides the pressurized anti-corrosion coating material to the feeding pipe 241.
[0059] The spraying assembly 24 includes a feed pipe 241, a paint nozzle 242, and a pipe cap 243. The feed pipe 241 is threadedly connected to the side of the material pump base 233 away from the distribution box 213. The side of the feed pipe 241 near the distribution box 213 is connected to the output end of the material pump 232. The paint nozzle 242 is connected to the side of the feed pipe 241 away from the distribution box 213. The pipe cap 243 is threadedly connected to the front side of the feed pipe 241. By setting up the spraying assembly 24, the feed pipe 241 serves as a guide structure for the anti-corrosion coating material, guiding the anti-corrosion coating material to the paint nozzle 242. The paint nozzle 242 serves as a spraying structure for the anti-corrosion coating material, spraying the anti-corrosion coating material onto the inner wall of the cable protection pipe. The pipe cap 243 is a structure that closes the feed pipe 241. It also features a built-in rubber sealing ring, which makes tight contact with the feed pipe 241. This allows the front of the feed pipe 241 to be sealed when no maintenance is required for the paint nozzle 242. The feed pipe 241, in conjunction with the paint nozzle 242 and the pipe cap 243, can evenly deliver the anti-corrosion coating material to the input end of each paint nozzle 242. The pressure continuously provided by the feed pump 232 then causes the paint nozzle 242 to spray the anti-corrosion coating material onto the inner wall of the cable protection pipe. The pipe cap 243 can seal the feed pipe 241 when no maintenance is required for the paint nozzle 242. When maintenance is needed, the paint nozzle 242 can be removed from the feed pipe 241 and maintained by opening the pipe cap 243.
[0060] The working principle of this embodiment is as follows: First, the pump 221, the feed pump 232, and the paint nozzle 242 are connected to a mobile battery and a signal processor via wires. Then, the pump 221, the feed pump 232, and the paint nozzle 242 are remotely connected to a PLC controller via the signal processor. The PLC controller then controls these components according to its preset program. Next, the feed bellows 222 is connected to the output end of the anti-corrosion coating material conveying equipment via the feed inlet 223. When anti-corrosion coating needs to be sprayed onto the inner wall of the cable protection pipe, since the distribution box 213 is bolted to the positioning plate 132, and the positioning plate 132 is linked with the output shaft of the second servo motor 131, the transmission plate 134 rotates synchronously. The distribution bellows 231 also adapts to the rotation of the distribution box 213. When the adaptation slide 141 moves circumferentially with the movement of the Mecanum wheel 153, the pump base 233 also adapts to the circumferential movement of the adaptation slide 141. The moving mechanism 1 moves along with the entire structure of the feeding pump 232 and the spraying assembly 24. When the anti-corrosion coating material is sent from the anti-corrosion coating material conveying equipment to the extraction pump 221 through the feeding bellows 222 and the inlet 223, the extraction pump 221 pressurizes the anti-corrosion coating material and delivers it to the positioning box 211. The positioning box 211 and the distribution box 213 are gradually filled. Then, the distribution box 213 delivers the anti-corrosion coating material to each feeding pump 232 through the distribution bellows 231. The feeding pump 232 pressurizes the anti-corrosion coating material again and delivers it to the feeding pipe 241. The feeding pipe 241 delivers the pressurized anti-corrosion coating material evenly to each paint nozzle 242. The paint nozzle 242 sprays the anti-corrosion coating material evenly on the inner wall of the cable protection pipe along the way until the entire structure of the moving mechanism 1 moves to the final destination to complete the anti-corrosion coating spraying operation on the inner wall of the cable protection pipe.
