Description

Technical Field

[0001] This utility model relates to the field of pipeline rust removal technology, specifically a crawling device for pipeline cleaning. Background Technology

[0002] After long-term use, metal pipes will develop rust on their inner walls, which will seriously affect the efficiency and service life of the pipeline. At present, the main methods for removing rust from the inner walls of pipelines are mechanical rust removal, chemical cleaning and dry pressure water jet cleaning.

[0003] Mechanical rust removal involves scraping away rust using mechanical devices such as wire brushes and grinding wheels, but it suffers from incomplete cleaning, damage to pipe walls, and difficulty adapting to different pipe diameters. Chemical cleaning uses acid or alkaline solutions to dissolve rust, but it generates a large amount of waste liquid, posing an environmental pollution risk and corrosive to pipe materials. High-pressure water jetting requires large equipment, consumes a lot of energy, suffers from severe water pressure attenuation in long-distance pipelines, and generates a large amount of wastewater.

[0004] In summary, a crawling device for pipe cleaning is proposed to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a crawling device for pipe cleaning. It has the advantages of being adaptable to different pipe diameters, using a purely physical cleaning process that is non-contact, without causing mechanical damage to the pipe substrate, without generating any chemical waste liquid, and using a wired power supply to achieve a stable energy supply. It solves the problems of traditional mechanical rust removal damaging the pipe wall, chemical cleaning polluting the environment, poor adaptability of traditional equipment, and limited energy supply due to long distances.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A crawling device for pipe cleaning includes a columnar body, a laser processing head and a rotary fiber optic connector. The columnar body is rotatably connected to a mounting column extending to its front side. The outer side of the mounting column is fixedly connected to an external gear ring located inside the columnar body. The columnar body is provided with a rotary drive assembly that meshes with the external gear ring. The outer side of the front end of the mounting column is embedded with a laser processing head extending to its interior. The input end of the laser processing head is coupled to a rotary fiber optic connector extending to the rear side of the mounting column.

[0009] The rear side of the column is provided with an adjustment component extending into it. The outer side of the column is provided with irregularly shaped grooves arranged in a ring array. The interior of each irregularly shaped groove is provided with an outward expansion component that is symmetrically distributed front and back and extends into the interior of the column. The opposite ends of each outward expansion component are engaged with the adjustment component. The opposite ends of adjacent outward expansion components are provided with the same irregularly shaped block that is adapted to the irregularly shaped groove. The interior of each irregularly shaped block is provided with a traveling component extending to its opposite side.

[0010] The rear side of the column is fitted with a wire protection tube, and the interior of the rear side of the column is provided with a bent wire passage that communicates with the wire protection tube. The interior of the rear side of the column is provided with an annular wire passage that communicates with the bent wire passage.

[0011] The beneficial effects of this utility model are:

[0012] This crawling device for pipe cleaning inserts a cylindrical body into a metal pipe. A rotating adjustment component drives an expansion component, which in turn moves the irregularly shaped block synchronously to the opposite side until the traveling components are in close contact with the inner wall of the pipe. A servo driver then moves the traveling components, propelling the device inside the metal pipe. During this process, the servo driver activates a rotary drive component, which in turn drives the mounting column and the laser processing head on its outer side to rotate via an external gear ring. Simultaneously, a high-energy pulsed laser beam emitted by the laser cleaning machine is transmitted to the laser processing head via fiber optic cable and a rotating fiber optic connector. The high-energy pulsed laser beam then irradiates the rust layer on the inner wall of the metal pipe. The rust instantly absorbs the laser energy and rapidly heats up, causing vibration, vaporization, or plasma expansion, thus peeling the rust off the inner wall substrate. This device offers advantages such as adaptability to different pipe diameters, a purely physical cleaning process, non-contact cleaning, no mechanical damage to the pipe substrate, no chemical waste, and a stable energy supply via wired power.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the adjustment assembly includes a bolt head shaft and a first bevel gear. The bolt head shaft extending into the rear side of the column is rotatably connected, and the first bevel gear distributed in a front-to-back manner is fixedly connected to the outer side of the bolt head shaft.

[0015] Furthermore, the expansion assembly includes an internally threaded cylinder, a lead screw, and a second bevel gear. The bottom of each of the irregular grooves is rotatably connected to an internally threaded cylinder that is distributed front to back and extends into the interior of the columnar body. The interior of each internally threaded cylinder is threadedly connected to a lead screw that extends into the irregular groove. One end of each adjacent lead screw is fixedly connected to the same irregular block that is adapted to the irregular groove. The other end of each lead screw is fixedly connected to a second bevel gear located inside the columnar body and meshing with the first bevel gear.

[0016] The beneficial effect of adopting the above-mentioned further solution is that the bolt head shaft is driven by the power tool to rotate the first bevel gear. Since the first bevel gear meshes with the second bevel gear, it drives the internal threaded cylinder to rotate. The rotation of the threads on the inner wall of the internal threaded cylinder generates a force that pushes the irregular block through the lead screw, causing the irregular block to move synchronously to the opposite side.

[0017] Furthermore, the traveling component includes a miniature dual-output shaft motor, a wheel axle, and a third bevel gear. Each of the irregular blocks is equipped with a miniature dual-output shaft motor. Each of the irregular blocks is rotatably connected to a wheel axle that is distributed front and back and located on the front and back sides of the miniature dual-output shaft motor and extends to the opposite side of the irregular block. The output end of the miniature dual-output shaft motor and the outer side of the wheel axle are fixedly connected to a meshing third bevel gear.

[0018] Furthermore, each of the irregular blocks is provided with a power spring wire electrically connected to a miniature dual-axis motor on one side, and the other end of each miniature dual-axis motor is electrically connected to an external power source through an annular wire channel, a bent wire channel, and a protective tube.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the irregular block moves synchronously to the opposite side, and the power spring wire is stretched at the same time until the wheel and axle are in close contact with the inner wall of the pipe. The servo driver causes the output end of the micro dual-axis motor to drive the wheel and axle to rotate synchronously through the third bevel gear, so that the device can move inside the metal pipe.

[0020] Furthermore, the rotary drive assembly includes a servo motor and a spur gear. The interior of the cylindrical body is equipped with a servo motor that is electrically connected to an external power source through a bent wire guide and a wire protection tube. The output end of the servo motor is fixedly connected to a spur gear that meshes with an external gear ring.

[0021] Furthermore, the stator end of the rotary fiber optic connector is fixed inside the column, the rotor end of the rotary fiber optic connector is fixed to the rear side of the mounting column, the stator end of the rotary fiber optic connector is provided with an optical fiber cable, and the optical fiber cable is connected to the output end of the laser cleaning machine through a bending cable channel and a protective tube.

[0022] The beneficial effect of adopting the above-mentioned further solution is that, during the process of the device moving inside the metal pipe, the servo driver causes the output end of the servo motor to drive the spur gear to rotate. Since the spur gear meshes with the external gear ring, it then drives the mounting column and the laser processing head on its outside to rotate through the meshing of the external gear ring. At the same time, the high-energy pulsed laser beam emitted by the laser cleaning machine is transmitted to the laser processing head through the optical fiber cable and the rotary optical fiber connector. Finally, the high-energy pulsed laser beam irradiates the rust layer on the surface of the inner wall of the metal pipe. The rust will instantly absorb the laser energy and rapidly heat up, producing vibration, vaporization or plasma expansion, thereby causing the rust to be peeled off from the surface of the inner wall of the pipe.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] In the embodiments, by Figure 1-4 The present invention discloses a crawling device for pipe cleaning. The present invention includes a columnar body 1, a laser processing head 2, and a rotary fiber optic connector 3. The columnar body 1 is rotatably connected to a mounting post 4 extending to its front side. The outer side of the mounting post 4 is fixedly connected to an external gear ring 5 located inside the columnar body 1. The columnar body 1 is provided with a rotary drive assembly 6 that meshes with the external gear ring 5. The laser processing head 2 extending to its interior is embedded on the outer side of the front end of the mounting post 4. The input end of the laser processing head 2 is coupled to a rotary fiber optic connector 3 extending to the rear side of the mounting post 4.

[0030] The rear side of the columnar body 1 is provided with an adjustment component 7 extending into it. The outer side of the columnar body 1 is provided with irregularly shaped grooves 8 arranged in a ring array. The interior of each irregularly shaped groove 8 is provided with an outward expansion component 9 arranged symmetrically front and back and extending into the interior of the columnar body 1. The opposite ends of each outward expansion component 9 are engaged with the adjustment component 7. The opposite ends of adjacent outward expansion components 9 are provided with the same irregularly shaped block 10 that is adapted to the irregularly shaped groove 8. The interior of each irregularly shaped block 10 is provided with a traveling component 11 extending to its opposite side.

[0031] The rear side of the column 1 is provided with a wire protection tube 12, and the interior of the rear side of the column 1 is provided with a bent wire passage 13 that communicates with the wire protection tube 12. The interior of the rear side of the column 1 is provided with an annular wire passage 14 that communicates with the bent wire passage 13.

[0032] The adjusting assembly 7 includes a bolt head shaft 701 and a first bevel gear 702. The bolt head shaft 701 extending into the rear side of the columnar body 1 is rotatably connected, and the first bevel gear 702 distributed in a front-to-back manner is fixedly connected to the outer side of the bolt head shaft 701.

[0033] The expansion assembly 9 includes an internally threaded cylinder 901, a lead screw 902, and a second bevel gear 903. The bottom of each of the irregular grooves 8 is rotatably connected to an internally threaded cylinder 901 that is distributed front to back and extends into the interior of the columnar body 1. The interior of each internally threaded cylinder 901 is threadedly connected to a lead screw 902 that extends into the irregular groove 8. One end of each adjacent lead screw 902 is fixedly connected to the same irregular block 10 that is adapted to the irregular groove 8. The other end of each lead screw 902 is fixedly connected to a second bevel gear 903 located inside the columnar body 1 and meshing with the first bevel gear 702.

[0034] The power tool drives the bolt head shaft 701 to rotate the first bevel gear 702. Since the first bevel gear 702 meshes with the second bevel gear 903, it drives the internal thread cylinder 901 to rotate. The rotation of the threads on the inner wall of the internal thread cylinder 901 generates force that pushes the irregular block 10 through the lead screw 902, causing the irregular block 10 to move synchronously to the opposite side.

[0035] The traveling component 11 includes a miniature dual-output shaft motor 111, a wheel axle 112, and a third bevel gear 113. Each of the irregular blocks 10 is equipped with a miniature dual-output shaft motor 111. Each of the irregular blocks 10 is rotatably connected to a wheel axle 112 that is distributed front and back and located on the front and back sides of the miniature dual-output shaft motor 111 and extends to the opposite side of the irregular block 10. The output end of the miniature dual-output shaft motor 111 and the outer side of the wheel axle 112 are fixedly connected to a meshing third bevel gear 113.

[0036] Each of the opposite sides of the irregular block 10 is provided with a power spring wire 15 electrically connected to the micro dual-output shaft motor 111. The other end of the micro dual-output shaft motor 111 is electrically connected to an external power source through an annular wire channel 14, a bent wire channel 13 and a protective tube 12.

[0037] The irregular block 10 moves synchronously to the opposite side, and the power spring wire 15 is stretched at the same time until the wheel axle 112 is in close contact with the inner wall of the pipe. The servo driver causes the output end of the micro dual-axis motor 111 to drive the wheel axle 112 to rotate synchronously through the third bevel gear 113, so that the device can move inside the metal pipe.

[0038] The rotary drive assembly 6 includes a servo motor 601 and a spur gear 602. The interior of the columnar body 1 is provided with a servo motor 601 that is electrically connected to an external power source through a bent wire channel 13 and a wire protection tube 12. The output end of the servo motor 601 is fixedly connected to a spur gear 602 that meshes with the external gear ring 5.

[0039] The stator end of the rotary fiber optic connector 3 is fixed inside the column 1, the rotor end of the rotary fiber optic connector 3 is fixed to the rear side of the mounting column 4, the stator end of the rotary fiber optic connector 3 is provided with an optical fiber cable, and the optical fiber cable is connected to the output end of the laser cleaning machine through the bending cable channel 13 and the protective tube 12.

[0040] During the movement of the device inside the metal pipe, the servo driver causes the output of the servo motor 601 to drive the spur gear 602 to rotate. Since the spur gear 602 meshes with the external gear ring 5, it then drives the mounting column 4 and the laser processing head 2 on its outer side to rotate through the meshing of the external gear ring 5. At the same time, the high-energy pulsed laser beam emitted by the laser cleaning machine is transmitted to the laser processing head 2 through the optical fiber cable and the rotary optical fiber connector 3. Finally, the high-energy pulsed laser beam irradiates the rust layer on the surface of the inner wall of the metal pipe. The rust will instantly absorb the laser energy and rapidly heat up, producing vibration, vaporization or plasma expansion, thereby peeling the rust off the substrate surface of the inner wall of the pipe.

[0041] Working principle:

[0042] Step 1: Insert the cylindrical body 1 into the metal pipe, and use a power tool to drive the bolt head shaft 701 to rotate the first bevel gear 702. Since the first bevel gear 702 meshes with the second bevel gear 903, it drives the internal threaded cylinder 901 to rotate. The rotation of the threads on the inner wall of the internal threaded cylinder 901 generates a force that pushes the irregular block 10 through the lead screw 902, causing the irregular block 10 to move synchronously to the opposite side.

[0043] Step 2: The irregular block 10 moves synchronously to the opposite side, and the power spring wire 15 is stretched at the same time until the wheel axle 112 is in close contact with the inner wall of the pipe. The servo driver causes the output end of the micro dual-axis motor 111 to drive the wheel axle 112 to rotate synchronously through the third bevel gear 113, so that the device can move inside the metal pipe.

[0044] Step 3: As the device moves inside the metal pipe, the servo driver causes the output of the servo motor 601 to drive the spur gear 602 to rotate. Since the spur gear 602 meshes with the external gear ring 5, it then drives the mounting column 4 and the laser processing head 2 on its outer side to rotate through the meshing of the external gear ring 5. At the same time, the high-energy pulsed laser beam emitted by the laser cleaning machine is transmitted to the laser processing head 2 through the optical fiber cable and the rotary optical fiber connector 3. Finally, the high-energy pulsed laser beam irradiates the rust layer on the surface of the inner wall of the metal pipe. The rust will instantly absorb the laser energy and rapidly heat up, producing vibration, vaporization or plasma expansion, thereby peeling the rust off the substrate surface of the inner wall of the pipe.
