Description

Technical Field

[0001] The present invention belongs to the technical field of power pipe processing, and particularly relates to a device for cement mortar lining of a metal-structured power pipe and a lining method thereof. Background Art

[0002] Power pipes are pipe systems used to protect and lay power cables, ensuring the safe operation and easy maintenance of the cables. The cement mortar lining process for power pipes is a technology for protecting metal power pipes. By forming a layer of cement mortar lining on the inner wall of the metal pipe, it plays roles such as anti-corrosion, wear resistance, and enhanced structural strength. However, there are the following several types of cement mortar lining processes for power pipes: spraying method: using high-pressure spraying equipment to evenly spray the mortar on the pipe wall; centrifugal method: after injecting the mortar into the pipe, making the mortar evenly adhere to the pipe wall through high-speed rotation; manual smearing method: applicable to small-diameter or local repair.

[0003] When currently carrying out cement mortar lining processing on power pipes, usually the power pipe is placed on a rotating wheel, and workers manually shovel the mixed cement into one end of the power pipe with a spade. Through the rotation of the rotating wheel, the power pipe is driven to rotate at a high speed, so that the cement mortar evenly adheres to the pipe wall to achieve the lining process. However, in this process, manual feeding by workers is not only time-consuming and laborious; at the same time, due to manual feeding, the feeding speed is not accurate enough, resulting in uneven distribution of the mortar on the pipe wall; and when the cement mortar is at the edge of the pipe wall, the high-speed rotation of the power pipe may cause the mortar to splash everywhere towards the outer end, not only causing waste of the mortar, but also splashing on the workers and affecting the construction. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a device for cement mortar lining of a metal-structured power pipe and a lining method thereof.

[0005] The technical solution adopted to solve the above technical problem is: A device for cement mortar lining of a metal-structured power pipe includes two support frames. Between the two support frames, there are two rotating mechanisms, and protective mechanisms are installed on the tops of both support frames;

[0006] At the centers of the tops of both support frames, feeding mechanisms are installed. Scraper mechanisms are installed inside both feeding mechanisms. At the outer ends of the tops of both support frames, moving mechanisms are installed;

[0007] At the inner ends of both moving mechanisms, leveling mechanisms are installed, and power pipe bodies are arranged on the tops of both rotating mechanisms.

[0008] A first support plate is fixedly connected between the two support frames. A second support plate is fixedly connected between the two support frames and above the first support plate. Two first chutes and two second chutes are formed at the tops of the two support frames. Rack bars are fixedly connected to the rear ends of the tops of the two support frames. The two first chutes are used for the movement of the protection mechanism, and the two second chutes and the two rack bars are used for the movement of the moving mechanism.

[0009] Furthermore, the rotation mechanism includes a first hydraulic cylinder fixedly installed on the top of the first support plate. Buffer rods are installed at the four corners of the top of the first support plate near the first hydraulic cylinder. The top end of the piston of the first hydraulic cylinder is fixedly connected to a third support plate. The top ends of the plurality of buffer rods are fixedly connected to the bottom of the third support plate. Two bases are fixedly connected to the top of the third support plate. The centers of the two bases are rotatably connected to a rotating shaft. The outer walls of the two rotating shafts are fixedly connected with runners. A first motor is fixedly installed on the top of the third support plate. A first gear is fixedly connected to the outer wall of the output shaft of the first motor. One end of the outer wall of one of the rotating shafts is fixedly connected with a second gear.

[0010] Through the above technical solution, after the cement mortar falls into the main body of the power pipe, the corresponding first motor is started. The first gear connected to the output shaft drives the first gear to rotate, thereby driving the engaged second gear to rotate, thereby driving the connected rotating shaft to rotate, and further driving the runner to rotate, realizing the rotation of the main body of the power pipe, so that the cement mortar is evenly attached to the inner wall of the main body of the power pipe. The staff can adjust the height of the plurality of runners according to the diameter of the main body of the power pipe to ensure that the center of the main body of the power pipe is aligned with the center of the protection mechanism. The first hydraulic cylinder is started, so that the first hydraulic cylinder rises through the piston, thereby driving the corresponding runner to rise, realizing the height adjustment of the plurality of runners, and thus the inner lining processing of power pipe bodies with different diameters can be carried out, with strong functionality.

[0011] Furthermore, the protection mechanism includes a bottom plate arranged at one end of the top of the support frame. Two first sliding strips are fixedly connected to the bottom of the bottom plate. A material receiving box is arranged on one side of the bottom plate. A second hydraulic cylinder is fixedly installed on the top of the support frame near the other side of the bottom plate. A protective cover is fixedly connected to one side of the top of the bottom plate. A plurality of material discharging openings are formed at the bottom of the protective cover. A connecting cover is fixedly connected to the other side of the top of the bottom plate. The two first sliding strips are slidably connected to the corresponding first chutes. One end of the piston of the second hydraulic cylinder is fixedly connected to the bottom plate.

[0012] Through the above technical solution, the second hydraulic cylinder is started, and the piston is used to push the connected bottom plate, thereby driving the protective cover close to both ends of the main power pipe body, so that the feeding pipe is located inside the main power pipe body. At the same time, when the main power pipe body rotates at a high speed, the mortar at both ends of the inner wall of the main power pipe body splashes into the protective cover, thereby preventing the mortar from splashing onto the ground and the staff, ensuring the construction environment.

[0013] Furthermore, the feeding mechanism includes a feeding pipe fixedly connected between the protective cover and the connecting cover. One side of the top of the feeding pipe is fixedly connected with a feeding pipe, and the other side of the bottom of the feeding pipe is fixedly connected with a discharging pipe. The center of the feeding pipe is rotatably connected with a rotating pipe, and a spiral feeding knife is fixedly connected to the outer wall of the rotating pipe. A second motor is fixedly installed on one side of the connecting cover. A connecting ear is fixedly connected to the outer wall of the feeding pipe, and a first connecting shaft is rotatably connected between the connecting cover and the connecting ear. One end of the outer wall of the first connecting shaft is fixedly connected with a third gear, and one end of the outer wall of the rotating pipe is fixedly connected with a fourth gear.

[0014] Through the above technical solution, the staff puts the cement mortar into the feeding pipe through the feeding pipe. At the same time, the second motor is started, and the first connecting shaft is driven to rotate through the rotation of the output shaft, thereby driving the third gear to rotate, and then driving the fourth gear to rotate, so that the fourth gear drives the rotating pipe to rotate, thereby driving the spiral feeding knife to rotate, realizing the transportation of the cement mortar, and finally falling to the inner wall of the main power pipe body through the discharging pipe to realize feeding.

[0015] Furthermore, the top end of the feeding pipe penetrates through the top of the outer wall of the connecting cover. The output end of the second motor is fixedly connected with the first connecting shaft, and the third gear meshes with the fourth gear.

[0016] Through the above technical solution, the rotation of the output shaft of the second motor drives the first connecting shaft to rotate, so that the first connecting shaft drives the third gear to rotate, and then drives the fourth gear to rotate.

[0017] Furthermore, the scraping mechanism includes a fifth gear fixedly connected to the other end of the outer wall of the first connecting shaft. One end of the outer wall of the feeding pipe is rotatably connected with a connecting sleeve. The other end of the outer wall of the connecting sleeve is fixedly connected with a toothed ring. One end of the outer wall of the connecting sleeve is fixedly connected with an L-shaped scraping bar. The fifth gear meshes with the toothed ring, and the L-shaped scraping bar is located inside the protective cover.

[0018] Through the above technical solution, at the same time, the rotation of the first connecting shaft drives the fifth gear to rotate, thereby driving the toothed ring to rotate, so that the toothed ring drives the connecting sleeve to rotate, thereby driving the L-shaped scraping bar to rotate, thereby scraping off the mortar attached to the inner wall of the protective cover. The scraped mortar falls into the receiving box through the discharging port. The staff pours the full receiving box into the feeding pipe and uses it again, reducing the use cost.

[0019] Further, the moving mechanism includes a moving frame disposed at the other end of the top of the support frame. A connecting plate is fixedly connected to the center of the moving frame. Two second sliding strips are fixedly connected to the bottom of the moving frame. A third motor is fixedly installed on the rear end of the inner surface of the bottom of the moving frame. A sixth gear is fixedly connected to the outer wall of the output shaft of the third motor. The two second sliding strips are slidably connected to the corresponding second sliding grooves. The sixth gear meshes with the corresponding rack.

[0020] Through the above technical solution, when the third motor is started, the sixth gear is driven to rotate on the rack by the rotation of the output shaft, so that the moving frame drives the leveling mechanism to move, enabling the leveling mechanism to fully level the cement mortar adhering to the inner wall of the main body of the power pipe.

[0021] Further, the leveling mechanism includes a second connecting shaft rotatably connected to the top of the moving frame. The second connecting shaft penetrates through the rotating pipe. A fourth motor is fixedly installed at the center of the top of the connecting plate. A seventh gear is fixedly connected to the outer wall of the second connecting shaft. An eighth gear is fixedly connected to the outer wall of the output shaft of the fourth motor. The eighth gear meshes with the seventh gear. The other end of the center of the second connecting shaft is threadedly connected to a threaded rod. A rotating head is fixedly connected to the bottom end of the threaded rod. A threaded sleeve is threadedly connected to the outer wall of the threaded rod. Two limiting grooves are formed on the outer wall of the threaded sleeve. A limiting sleeve is fixedly connected to one end of the outer wall of the second connecting shaft near the outer wall of the threaded sleeve. Two limiting strips are fixedly connected to the inner wall of the limiting sleeve. The two limiting strips are slidably connected to the corresponding limiting grooves. A spring is fixedly connected to the top center of the threaded sleeve. A movable pin is fixedly connected to the top of the spring. The movable pin is slidably connected to the threaded sleeve. A leveling plate is fixedly connected to the top end of the movable pin.

[0022] Through the above technical solution, under the action of the moving mechanism, the leveling plate slowly contacts the mortar adhering to the inner wall of the main body of the power pipe. When the fourth motor is started, the eighth gear is driven to rotate by the rotation of the output shaft, thereby driving the seventh gear to rotate, and further driving the second connecting shaft to rotate. Under the action of the spring, the leveling plate levels the mortar adhering to the inner wall of the main body of the power pipe, solving the problem of uneven adhesion of the cement mortar. When it is necessary to adjust the leveling plate according to the diameter of the main body of the power pipe in the later stage, rotate the rotating head, thereby driving the threaded rod to rotate, and then driving the threaded sleeve to move within the limiting sleeve, and the adjustment of the leveling plate can be realized. It has strong functionality and can be used for power pipe main bodies with different diameters.

[0023] A lining method for a cement mortar inner lining device of a metal structure power pipe includes the following specific steps:

[0024] Step 1: The staff adjusts the heights of multiple rotating wheels according to the diameter of the main body of the power pipe to ensure that the center of the main body of the power pipe is aligned with the center of the protection mechanism. Start the first hydraulic cylinder, so that the first hydraulic cylinder rises through the piston, thereby driving the corresponding rotating wheel to rise. After adjustment, place the main body of the power pipe on multiple rotating wheels, start the corresponding first motor, drive the connected first gear to rotate through the output shaft, thereby driving the meshing second gear to rotate, thereby driving the connected rotating shaft to rotate, and then driving the rotating wheel to rotate, realizing the rotation of the main body of the power pipe;

[0025] Step 2: Start two second hydraulic cylinders, both of which push the connected bottom plate through the piston, thereby driving the two protective covers to approach both ends of the main body of the power pipe, so that the feeding pipe is located inside the main body of the power pipe. The staff puts the cement mortar into the feeding pipe through the feeding pipe. At the same time, start the second motor, drive the first connecting shaft to rotate through the rotation of the output shaft, thereby driving the third gear to rotate, thereby driving the fourth gear to rotate, so that the fourth gear drives the rotating pipe to rotate, thereby driving the spiral feeding knife to rotate, realizing the conveying of the cement mortar, and finally falling onto the inner wall of the main body of the power pipe through the feeding pipe to realize feeding;

[0026] Step 3: The main body of the power pipe rotates at a high speed through multiple rotating wheels, so that the cement mortar is evenly attached to the inner wall of the main body of the power pipe, and at the same time, it will also drive the mortar at the edge to splash into the protective cover. At this time, the first connecting shaft rotates to drive the fifth gear to rotate, thereby driving the toothed ring to rotate, so that the toothed ring drives the connecting sleeve to rotate, thereby driving the L-shaped scraping strip to rotate, thereby scraping off the mortar attached to the inner wall of the protective cover. The scraped mortar falls into the receiving box through the discharge port. The staff pours the full receiving box into the feeding pipe and uses it again;

[0027] Step 4: After the inner wall of the main body of the power pipe is attached with cement mortar, start the third motor, drive the sixth gear to rotate on the rack through the rotation of the output shaft, so that the moving frame drives the smoothing mechanism to move, so that the smoothing plate slowly contacts the mortar attached to the inner wall of the main body of the power pipe. Start the fourth motor, drive the eighth gear to rotate through the rotation of the output shaft, thereby driving the seventh gear to rotate, and then driving the second connecting shaft to rotate. Under the action of the spring, the smoothing plate levels the mortar attached to the inner wall of the main body of the power pipe;

[0028] Step 5: After the inner wall of the main body of the power pipe is leveled with cement mortar, the cement mortar lining process of the entire main body of the power pipe is realized. The protection mechanism, feeding mechanism, scraping mechanism, moving mechanism and smoothing mechanism are reset, and the staff removes the main body of the power pipe;

[0029] Step 6: When it is necessary to adjust the smoothing plate according to the diameter of the main body of the power pipe, rotate the rotating head, thereby driving the threaded rod to rotate, thereby driving the threaded sleeve to move in the limit sleeve, and the adjustment of the smoothing plate can be realized.

[0030] The beneficial effects of the present invention are as follows: (1) By designing a protection mechanism, a feeding mechanism, and a scraping mechanism, when lining the power pipe, the protective covers at both ends can block the sputtered mortar, ensuring the working environment. At the same time, the sputtered mortar can be scraped and collected for reuse, reducing the lining cost; (2) By designing a rotating mechanism, power pipes with different diameters can be supported, with strong functionality. At the same time, the center of the power pipe is ensured to be aligned with the protection mechanism, facilitating the lining process; (3) By designing a smoothing mechanism, after the cement mortar lining of the power pipe is completed, the attached cement mortar can be smoothed by the smoothing mechanism to prevent the unevenly attached cement mortar from affecting the final quality, greatly improving the lining accuracy. At the same time, it can be used for power pipes with different diameters, with strong functionality. Brief Description of the Drawings

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] As Figures 1 - 3 shown, a device for cement mortar lining inside a metal structure power pipe in this embodiment includes two support frames 1. A first support plate 11 is fixedly connected between the two support frames 1. A second support plate 12 is fixedly connected between the two support frames 1 and above the first support plate 11. Two first chutes 13 and two second chutes 14 are provided at the tops of the two support frames 1. Rack bars 15 are fixedly connected to the rear ends of the tops of the two support frames 1. The two first chutes 13 are used for the movement of the protection mechanism 3, and the two second chutes 14 and the two rack bars 15 are used for the movement of the moving mechanism 6. The tops of the two rotating mechanisms 2 are both provided with a main body 8 of a power pipe.

[0044] As Figures 1 - 9As shown in the figure, there are two rotating mechanisms 2 between the two support frames 1. The rotating mechanism 2 includes a first hydraulic cylinder 201 fixedly installed on the top of the first support plate 11. Buffer rods 202 are installed at the four corners of the top of the first support plate 11 near the first hydraulic cylinder 201. The piston top of the first hydraulic cylinder 201 is fixedly connected to a third support plate 203. The tops of multiple buffer rods 202 are fixedly connected to the bottom of the third support plate 203. Two bases 204 are fixedly connected to the top of the third support plate 203. The centers of the two bases 204 are rotatably connected to a rotating shaft 205. The outer walls of the two rotating shafts 205 are fixedly connected with runner wheels 206. A first motor 207 is fixedly installed on the top of the third support plate 203. The outer wall of the output shaft of the first motor 207 is fixedly connected with a first gear 208. One end of the outer wall of one of the rotating shafts 205 is fixedly connected with a second gear 209. After the cement mortar drops into the main body 8 of the power pipe, start the corresponding first motor 207, drive the connected first gear 208 to rotate through the output shaft, thereby driving the engaged second gear 209 to rotate, thereby driving the connected rotating shaft 205 to rotate, and further driving the runner wheel 206 to rotate, realizing the rotation of the main body 8 of the power pipe, so that the cement mortar is evenly attached to the inner wall of the main body 8 of the power pipe. The staff can adjust the height of multiple runner wheels 206 according to the diameter of the main body 8 of the power pipe to ensure that the center of the main body 8 of the power pipe is aligned with the center of the protection mechanism 3. Start the first hydraulic cylinder 201, so that the first hydraulic cylinder 201 rises through the piston, thereby driving the corresponding runner wheel 206 to rise, realizing the height adjustment of multiple runner wheels 206, and thus the inner lining processing of the main body 8 of the power pipe with different diameters can be carried out, with strong functionality.

[0045] As Figures 1 - 5 As shown in the figure, protection mechanisms 3 are installed on the tops of the two support frames 1. The protection mechanism 3 includes a bottom plate 301 arranged at one end of the top of the support frame 1. Two first sliding strips 302 are fixedly connected to the bottom of the bottom plate 301. A material receiving box 303 is arranged on one side of the bottom plate 301. A second hydraulic cylinder 304 is fixedly installed on the top of the support frame 1 near the other side of the bottom plate 301. One side of the top of the bottom plate 301 is fixedly connected with a protective cover 305. A plurality of material discharging openings 306 are opened at the bottom of the protective cover 305. The other side of the top of the bottom plate 301 is fixedly connected with a connecting cover 307. The two first sliding strips 302 are slidably connected with the corresponding first sliding grooves 13. One end of the piston of the second hydraulic cylinder 304 is fixedly connected with the bottom plate 301. Start the second hydraulic cylinder 304, push the connected bottom plate 301 through the piston, thereby driving the protective cover 305 to approach both ends of the main body 8 of the power pipe, so that the material discharging pipe 403 is located inside the main body 8 of the power pipe. At the same time, when the main body 8 of the power pipe rotates at a high speed, the mortar at both ends of the inner wall of the main body 8 of the power pipe splashes into the protective cover 305, thereby preventing the mortar from splashing onto the ground and the staff, ensuring the construction environment.

The staff puts the cement mortar into the feeding pipe 401 through the feeding pipe 402, and at the same time starts the second motor 406. The rotation of the output shaft drives the first connecting shaft 408 to rotate, thereby driving the third gear 409 to rotate, and then driving the fourth gear 410 to rotate, so that the fourth gear 410 drives the rotating pipe 404 to rotate, thereby driving the spiral feeding knife 405 to rotate, realizing the conveying of the cement mortar, and finally falling to the inner wall of the power pipe body 8 through the discharging pipe 403 to realize discharging.

At the same time, the rotation of the first connecting shaft 408 drives the fifth gear 501 to rotate, thereby driving the toothed ring 503 to rotate, so that the toothed ring 503 drives the connecting sleeve 502 to rotate, thereby driving the L-shaped scraping bar 504 to rotate, thereby scraping off the mortar attached to the inner wall of the protective cover 305. The scraped mortar falls into the material collecting box 303 through the discharging port 306. The staff pours the full material collecting box 303 into the feeding pipe 402 and uses it again, reducing the use cost.

[0048] As Figures 1 - 7As shown in the figure, moving mechanisms 6 are installed at the outer ends of the tops of the two support frames 1. The moving mechanism 6 includes a moving frame 601 arranged at the other end of the top of the support frame 1. A connecting plate 602 is fixedly connected to the center of the moving frame 601.

When the third motor 604 is started, the sixth gear 605 is driven to rotate on the rack 15 through the rotation of the output shaft, so that the moving frame 601 drives the leveling mechanism 7 to move, enabling the leveling mechanism 7 to fully level the cement mortar adhering to the inner wall of the power pipe body 8.

[0049] As Figures 1 - 10 shown, leveling mechanisms 7 are installed at the inner ends of the two moving mechanisms 6. The leveling mechanism 7 includes a second connecting shaft 701 rotatably connected to the top of the moving frame 601. The second connecting shaft 701 penetrates through the rotating pipe 404. A fourth motor 702 is fixedly installed at the center of the top of the connecting plate 602. A seventh gear 703 is fixedly connected to the outer wall of the second connecting shaft 701. An eighth gear 704 is fixedly connected to the outer wall of the output shaft of the fourth motor 702. The eighth gear 704 meshes with the seventh gear 703.

A threaded sleeve 707 is threadedly connected to the outer wall of the threaded rod 705. Two limiting grooves 708 are formed on the outer wall of the threaded sleeve 707. Two limiting strips 710 are fixedly connected to the outer wall of one end of the second connecting shaft 701 close to the outer wall of the threaded sleeve 707.

A movable pin 712 is fixedly connected to the top of the spring 711. The movable pin 712 is slidably connected to the threaded sleeve 707. A leveling plate 713 is fixedly connected to the top end of the movable pin 712. Under the action of the moving mechanism 6, the leveling plate 713 slowly contacts the mortar adhering to the inner wall of the power pipe body 8. When the fourth motor 702 is started, the eighth gear 704 is driven to rotate through the rotation of the output shaft, thereby driving the seventh gear 703 to rotate, and further driving the second connecting shaft 701 to rotate. Under the action of the spring 711, the leveling plate 713 levels the mortar adhering to the inner wall of the power pipe body 8, solving the problem of uneven adhesion of the cement mortar. When the leveling plate 713 needs to be adjusted according to the diameter of the power pipe body 8 in the later stage, rotate the rotating head 706, thereby driving the threaded rod 705 to rotate, and further driving the threaded sleeve 707 to move within the limiting sleeve 709, so as to realize the adjustment of the leveling plate 713. It has strong functionality and can be used for power pipe bodies 8 with different diameters.

[0051] Step 1: The staff adjusts the heights of multiple rotating wheels 206 according to the diameter of the power pipe main body 8 to ensure that the center of the power pipe main body 8 is aligned with the center of the protection mechanism 3. Start the first hydraulic cylinder 201, so that the first hydraulic cylinder 201 rises through the piston, thereby driving the corresponding rotating wheel 206 to rise. After adjustment, place the power pipe main body 8 on the multiple rotating wheels 206, start the corresponding first motor 207, drive the connected first gear 208 to rotate through the output shaft, thereby driving the meshing second gear 209 to rotate, thereby driving the connected rotating shaft 205 to rotate, and further driving the rotating wheel 206 to rotate, realizing the rotation of the power pipe main body 8;

[0052] Step 2: Start two second hydraulic cylinders 304, both of which push the connected bottom plate 301 through the piston, thereby driving the two protective covers 305 to approach both ends of the power pipe main body 8, so that the feeding pipe 403 is located inside the power pipe main body 8. The staff puts the cement mortar into the feeding pipe 401 through the feeding pipe 402. At the same time, start the second motor 406, drive the first connecting shaft 408 to rotate through the output shaft rotation, thereby driving the third gear 409 to rotate, thereby driving the fourth gear 410 to rotate, so that the fourth gear 410 drives the rotating pipe 404 to rotate, thereby driving the spiral feeding knife 405 to rotate, realizing the conveying of the cement mortar, and finally dropping it onto the inner wall of the power pipe main body 8 through the feeding pipe 403 to realize feeding;

[0053] Step 3: The power pipe main body 8 rotates at a high speed through multiple rotating wheels 206, so that the cement mortar is evenly attached to the inner wall of the power pipe main body 8, and at the same time, the mortar at the edge will also be splashed into the protective cover 305. At this time, the first connecting shaft 408 rotates to drive the fifth gear 501 to rotate, thereby driving the toothed ring 503 to rotate, so that the toothed ring 503 drives the connecting sleeve 502 to rotate, thereby driving the L-shaped scraping strip 504 to rotate, thereby scraping off the mortar attached to the inner wall of the protective cover 305. The scraped mortar falls into the material collection box 303 through the material discharge port 306. The staff pours the full material collection box 303 into the feeding pipe 402 and uses it again;

[0054] Step 4: After the inner wall of the power pipe body 8 is attached with cement mortar, start the third motor 604. Drive the sixth gear 605 to rotate on the rack 15 through the rotation of the output shaft, so that the moving frame 601 drives the leveling mechanism 7 to move, making the leveling plate 713 slowly contact the mortar attached to the inner wall of the power pipe body 8. Start the fourth motor 702, drive the eighth gear 704 to rotate through the rotation of the output shaft, thereby driving the seventh gear 703 to rotate, and further driving the second connecting shaft 701 to rotate. Under the action of the spring 711, the leveling plate 713 levels the mortar attached to the inner wall of the power pipe body 8;

[0055] Step 5: After the cement mortar on the inner wall of the power pipe body 8 is leveled, the cement mortar lining process of the entire power pipe body 8 is completed. The protection mechanism 3, the feeding mechanism 4, the scraping mechanism 5, the moving mechanism 6, and the leveling mechanism 7 are reset, and the staff removes the power pipe body 8;

[0056] Step 6: When it is necessary to adjust the leveling plate 713 according to the diameter of the power pipe body 8, rotate the rotating head 706, thereby driving the threaded rod 705 to rotate, and then driving the threaded sleeve 707 to move within the limit sleeve 709, so as to realize the adjustment of the leveling plate 713.

[0057] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
