Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, and in particular to a sewer pipeline repair device and a repair method. Background Art

[0002] After long-term use, sewer pipes are usually damaged and affect their normal use. The traditional repair method is usually to excavate the sewer pipes and then repair them. This repair method will cause a large load on urban roads, and due to the complex pipeline layout and complex excavation construction, it is also difficult.

[0003] In order to improve the convenience of repair construction under the existing technology, it is usually repaired in a way that will not directly damage the sewer pipe. One of the ways is to spray paint on the inner wall of the pipe. However, due to the presence of many impurities on the surface of the sewer, the paint may not be evenly applied to the inner wall, and the impurities will also affect the adhesion of the paint to the sewer wall, affecting the repair effect. Summary of the invention

[0004] In order to solve the problem in the prior art that due to the presence of a large number of impurities on the surface of the sewer, the paint may not be evenly applied to the inner wall, and the impurities will also affect the adhesion of the paint to the sewer wall, affecting the repair effect, the present application provides a sewer pipe repair device, and the specific plan is as follows.

[0005] A sewer pipe repair device comprises a positioning frame, the positioning frame is arranged in a rectangular parallelepiped shape, a plurality of rotating wheels are rotatably arranged on the positioning frame, the rotating wheels abut against the inner wall of the sewer pipe with their remnants, and a motor for driving the rotating wheels to rotate is also arranged on the positioning frame; The positioning frame is also provided with a mounting block, one end of which is rotatably provided with a circular blade, a double-headed motor is arranged inside the mounting block, and a disk for storing water is also rotatably provided on the mounting block, a plurality of water spray guns for spraying water are equidistantly arranged on the disk, a motor shaft at one end of the double-headed motor is connected to the circular blade, and a motor shaft at the other end of the double-headed motor is used to drive the disk, a reducer is arranged between the double-headed motor and the disk, the reducer is connected to the double-headed motor, and an output shaft of the reducer is connected to the disk.

[0006] By adopting the above technical solution, a mounting block is arranged on the positioning frame, and the positioning frame can move along the sewer pipe under the drive of the rotating wheel. Since the positioning frame is a rectangular parallelepiped, the shape of the rectangular parallelepiped can play a positioning role, so that the positioning frame can move more stably in the sewer pipe and reduce the deviation. The circular blade can cut the impurities on the inner wall of the sewer pipe to reduce the influence of the impurities on the subsequent coating. At the same time, a water spray gun is arranged to further clean the impurities on the inner wall, which can further reduce the retention of impurities. At the same time, a double-headed motor is used to drive the circular blade and the disc body to rotate at the same time, thereby reducing the driving cost. The use of a reducer at the disc body can reduce the situation of excessive rotation speed.

[0007] Optionally, a debris removing shovel is also provided on the mounting block, and one debris removing shovel is provided on each circumferential side wall of the mounting block. The debris removing shovel is hinged to the mounting block, and a push rod is also slidably provided in the mounting block, one end of the push rod is transmission connected to the debris removing shovel, and the other end of the push rod is arranged at a position close to the output shaft of the reducer. A cam is fixedly provided on the output shaft, and the cam is used to abut the push rod, and the debris removing shovel is driven to rotate when the push rod is pushed.

[0008] By adopting the above technical scheme, a debris removing shovel is arranged on the mounting block, and the debris removing shovel can remove impurities on the inner wall of the sewer after completing the preliminary cutting, and the debris removing shovel is continuously pushed by the cam, so that the debris removing shovel can be moved away from the inner wall of the sewer pipe at a regular time to reduce the situation where the debris removing shovel and the inner wall of the sewer pipe interfere with each other and affect the movement, and the debris removing shovel can remove impurities at a certain frequency to ensure the debris removing effect of the debris removing shovel. Since the debris removing shovel has a certain curvature when rotating, it can remove impurities within a certain range without having to abut against the inner wall of the pipe all the time to remove impurities.

[0009] Optionally, a gear is provided on the push rod debris shovel, and a rack is provided on the push rod corresponding to the gear, and the corresponding gear and rack are meshed with each other.

[0010] By adopting the above technical solution, gears and racks are arranged to drive the debris shovel, so that the debris shovel is more stable during transmission, and the cleaning effect of the debris shovel is improved.

[0011] Optionally, a spring is further provided between the push rod and the mounting block, and the spring has a tendency to drive the push rod to move toward the motor shaft.

[0012] By adopting the above technical solution, a spring is arranged between the push rod and the mounting block, and the spring can drive the push rod to move toward the motor shaft. When the cam abuts against the push rod, the debris shovel can be retracted. The cooperation with the cam can not only reduce the situation where the debris shovel always abuts against the inner wall of the sewer pipe and affects the movement of the positioning frame, but also can reset the debris shovel to clean the impurities on the inner wall of the sewer pipe when the cam abuts. The cooperation of the cam and the spring rotates the debris removing rod back and forth to form a back and forth shoveling action, thereby further improving the cleaning effect of impurities.

[0013] Optionally, the debris removal shovel is arranged in an arc shape and corresponds to the shape of the inner wall of the sewer.

[0014] By adopting the above technical solution, the debris shovel is set in an arc shape and corresponds to the shape of the inner wall of the sewer. The arc-shaped setting can better fit the inner wall of the sewer pipe to remove impurities, which can further improve the debris shovel's effect of removing impurities and improve the cleaning effect of impurities.

[0015] Optionally, when each of the push rods moves, the debris removing shovel rotates toward a side away from the circular blade.

[0016] By adopting the above technical solution, the impurity removing shovel can rotate toward the same side when the push rod moves, thereby reducing the situation where impurities are scraped toward one side of the circular blade and affect the rotation of the circular blade.

[0017] Optionally, the debris removal shovel is arranged between the disc body and the circular blade.

[0018] By adopting the above technical solution, the debris removing shovel is set between the disc body and the circular dividing blade, which can first cut the impurities. After cutting, some impurities can be pushed by the debris removing shovel to peel off from the inner wall, while some impurities cannot be peeled off from the inner wall. At this time, the inner wall is flushed with a water gun to flush the impurities from the inner wall, thereby further improving the cleaning effect of the inner wall of the sewer.

[0019] Optionally, the rotating wheels are respectively arranged on eight corners of the positioning frame.

[0020] By adopting the above technical solution, the rotating wheels are arranged on the eight corners of the positioning frame, and the rotating wheels on the upper and lower sides can abut against the inner wall of the sewer, so that the inner wall of the sewer can be used for positioning, making the positioning frame more stable during movement and reducing the displacement of the positioning frame during movement.

[0021] The present application also provides a sewer pipe repair method, comprising the sewer pipe repair device described above, using the following method: a. Put the repair device into the sewer and control the repair device to move along the sewer pipe; b. Start the circular blade to cut the impurities on the sewer wall; c. Start the debris removal shovel and water spray gun to remove impurities on the sewer wall; d. Take out the repair device and spray the repair paint on the wall of the sewer.

[0022] By adopting the above technical solution, the inner wall of the sewer pipe is first cleaned by the repair device, and then the paint is sprayed, thereby improving the adhesion rate of the paint and enhancing the repair effect of the paint on the sewer pipe.

[0023] To sum up, the present application has at least the following beneficial effects: the inner wall of the sewer pipe is first cleaned by a repair device, and then the paint is sprayed after cleaning, which can reduce the situation where impurities adhere to the inner wall of the sewer and affect the adhesion effect of the paint, and improve the repair effect of the paint on the sewer pipe.

[0024] 1. The present application solves the problem in the prior art that due to the presence of a large number of impurities on the surface of the sewer, the paint may not be evenly applied to the inner wall, and the impurities will also affect the adhesion of the paint to the wall of the sewer, thus affecting the repair effect. The present application sets a positioning frame that can move in the sewer pipe. During the movement, the circular blade can cut and remove the impurities on the wall of the sewer pipe. After cutting, the debris removal shovel can peel off the impurities on the wall of the sewer pipe again, remove the cut impurities from the wall of the sewer pipe, and then flush the wall of the sewer pipe again with water through a water spray gun, thereby further improving the cleaning effect.

[0025] 2. The present application also provides a reducer and a cam, and the movement of the cam can drive the debris removal shovel to perform a reciprocating cycle to remove impurities, which can not only improve the effect of removing impurities, but also reduce the situation where the debris removal shovel is always in contact with the wall of the sewer pipe and affects the movement of the repair device. At the same time, it can cooperate with the spring cycle to drive the debris removal shovel to reciprocate, thereby achieving the removal of impurities.

[0026] 3. The present application also provides a rectangular positioning frame so that the entire device can form an interference contact with the inner wall of the sewer, making it difficult for the device to deviate, making the entire device more stable during movement and reducing the possibility of getting stuck due to deviation.

Water spray gun; DETAILED DESCRIPTION The present application is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0030] A sewer pipe repair device, such as Figure 1 and Figure 2 As shown, it includes a positioning frame 1, which is arranged in a rectangular parallelepiped shape. A plurality of rotating wheels 11 are rotatably arranged on the positioning frame 1. The rotating wheels 11 abut against the inner wall of the sewer pipe with a surplus. The positioning frame 1 is also provided with a motor for driving the rotating wheels 11 to rotate. In specific implementation, the rotating wheels 11 can be controlled by remote control. The rotating wheels 11 of the positioning frame 1 can abut against the upper and lower sides. The rectangular parallelepiped arrangement of the positioning frame 1 can also be fitted into a circular or elliptical sewer pipe, and it is not easy to deviate when moving. In this embodiment, only one rotating wheel 11 is provided with a motor, and the other rotating wheels 11 can follow. The entire positioning frame 1 can be driven to move by one motor. In other embodiments, the direction of the rotating wheel 11 can also be changed, so that the rotating wheel 11 fits the shape of the sewer pipe more closely, further improving the stability of the positioning frame 1 when moving.

[0031] like Figure 1 and Figure 2 As shown, the positioning frame 1 is also provided with a mounting block 2, one end of which is rotatably provided with a circular blade 26, and a double-headed motor 21 is arranged inside the mounting block 2. A disk 3 for storing water is also rotatably provided on the mounting block 2, and a plurality of water spray guns for spraying water are equidistantly arranged on the disk 3. The motor shaft at one end of the double-headed motor 21 is connected to the circular blade 26, and the motor shaft at the other end of the double-headed motor 21 is used to drive the disk 3. A reducer 22 is arranged between the double-headed motor 21 and the disk 3, and the reducer 22 is connected to the double-headed motor 21, and the output shaft 221 of the reducer 22 is connected to the disk 3. During specific implementation, the circular blade 26 is directed toward the direction in which it needs to move forward, cutting first and then flushing. The double-headed motor 21 can simultaneously drive the circular blade 26 and the disc body 3 to rotate. Since the disc body 3 is sprayed with water, the speed reducer 22 is provided to reduce the rotation speed to a certain extent. The interior of the disc body 3 is hollowed out, and the water used for cleaning is stored in the interior of the disc body 3. Cleaning agents can also be mixed into the water. The water spray gun uses a pressurized method to spray water from the disc body 3, thereby flushing the inner wall of the sewer pipe, further improving the cleaning effect.

[0032] like Figure 1 and Figure 2As shown, the mounting block 2 is also provided with a debris shovel 23, and one is provided on each side wall along the circumference of the mounting block 2, that is, except for the two ends in the length direction of the mounting block 2, one is provided on each side wall of the mounting block 2. The debris shovel 23 is hinged to the mounting block 2, and a push rod 24 is also slidably provided in the mounting block 2, one end of the push rod 24 is transmission-connected with the debris shovel 23, and the other end of the push rod 24 is provided at a position close to the output shaft 221 of the reducer 22, and a cam 222 is fixedly provided on the output shaft 221 of the reducer 22, and the cam 222 is used to abut against the push rod 24, and the push rod 24 drives the debris shovel 23 to rotate when it is pushed. In specific implementation, the push rod 24 can move along the mounting block 2, and the cam 222 is fixedly connected to the push rod 24. The cam 222 is arranged in an arc shape as a whole to reduce interference during rotation. The cam 222 can push each push rod 24 to move in sequence during rotation. The push rod 24 can push the debris shovel 23 to rotate during movement, thereby removing impurities on the inner wall of the sewer pipe, thereby completing the subsequent cleaning of impurities on the wall, and reducing the situation where impurities on the wall surface remain on the wall surface after being cut. In addition, by repeatedly driving the cam 222, the situation where the debris shovel 23 abuts against the wall surface for a long time and affects the movement can be reduced, so that the debris shovel 23 can move and reduce the deviation. In other embodiments, multiple cams 222 can be set on the output shaft 221 of the reducer 22 to increase the movement frequency of the debris shovel 23, further increase the frequency of removing impurities, and improve the cleaning efficiency, but it is also easy to cause abutment and affect the movement.

[0033] like Figure 1 and Figure 2 As shown, a gear 231 is provided on the push rod 24 and the debris shovel 23, and a rack 241 is provided on the push rod 24 corresponding to the gear 231, and the corresponding gear 231 and the rack 241 mesh with each other. In specific implementation, when the push rod 24 is pushed, it can drive the corresponding debris shovel 23 to rotate, and the rotation process is smoother, and the linkage mode of the gear 231 and the rack 241 makes it difficult for the debris shovel 23 to move when the push rod 24 does not move, thereby further improving stability. In other embodiments, a connecting rod can be provided between the debris shovel 23 and the push rod 24, one end of the connecting rod is hinged to the debris shovel 23, and the other end of the connecting rod is hinged to the debris shovel 23, so that when the push rod 24 moves, the debris shovel 23 can be driven to rotate, and transmission can also be achieved.

[0034] like Figure 1 and Figure 2As shown, a spring 25 is also provided between the push rod 24 and the mounting block 2, and the spring 25 has a tendency to drive the push rod 24 to move toward the motor shaft. When each push rod 24 moves, the debris shovel 23 rotates toward the side away from the circular blade 26. During specific implementation, one end of the spring 25 is fixedly connected to the inside of the mounting block 2, and the other end of the spring 25 is fixedly connected to the push rod 24. In normal state, the spring 25 will drive the transmission rod toward the motor shaft. At this time, under the action of the push rod 24, the debris shovel 23 will abut against the inner wall of the pipe, and continuously clean up the debris cut on the inner wall of the sewer pipe. When the cam 222 abuts and pushes the push rod 24 once, the debris shovel 23 rotates toward the side away from the circular blade 26, completing a debris shoveling action, and throwing the debris accumulated on the debris shovel 23 downward. At the same time, the debris shoveling action can throw a part of the debris off the inner wall of the sewer pipe with higher efficiency. When the cam 222 is moved away, the debris shovel 23 will reset again. Since the rotation efficiency of the cam 222 is not low, the debris shoveling action of the debris shovel 23 can be repeated, thereby improving the efficiency of debris removal, reducing the situation where impurities are still attached to the inner wall of the sewer pipe after being cut, and improving the effect of subsequent spraying and repairing.

[0035] like Figure 1 and Figure 2 As shown, the debris shovel 23 is arranged in an arc shape and corresponds to the shape of the inner wall of the sewer. In specific implementation, the debris shovel 23 is arranged in a fan-shaped arc shape as a whole, which just corresponds to the shape of the inner wall of the sewer. The bending direction of the debris shovel 23 in this application is toward the side away from the circular blade 26, and impurities will accumulate on the side close to the circular blade 26. In order to prevent the impurities from falling onto the mounting block 2 in this application, this design is adopted. In other embodiments, in order to better knock off the impurities, the bending direction of the debris shovel 23 can be toward the side close to the circular blade 26, and a collection basket for collecting impurities is set on the mounting block 2, and the impurities knocked off from the top are collected and processed. At this time, the cut impurities can be pushed down along the debris shovel 23 after accumulation, which can further improve the treatment effect of the impurities.

[0036] like Figure 1 and Figure 2 As shown, the impurity removal shovel 23 is arranged between the disc body 3 and the circular blade 26. In specific implementation, in this embodiment, the impurity removal shovel 23 is arranged near the disc body 3, and the impurities on the impurity removal shovel 23 can also be washed during the shower, which provides convenience for subsequent impurity removal. When the impurities are removed, the impurities can be cut by the blade first, and then washed by the liquid, so as to further improve the cleaning effect of the impurities. In other embodiments, the impurity removal shovel 23 can also be arranged behind the disc body 3. At this time, the attachment effect of the impurities can be reduced by spraying first, and then the impurities can be removed by the impurity removal shovel, so as to improve the efficiency of shoveling the attached objects, and also improve the cleaning efficiency.

[0037] like Figure 1 and Figure 2 As shown, the rotating wheels 11 are respectively arranged on the eight corners of the positioning frame 1. In specific implementation, the rotating wheels 11 on the eight feet of the positioning frame 1 can all abut against the inner wall of the sewer pipe, forming a guiding effect on the positioning frame 1, so that the positioning frame 1 is more stable when moving along the sewer pipe, and further reduces the situation where the positioning frame is offset and stuck during movement. In other embodiments, the positioning frame 1 can also be set as a column with an equilateral pentagon or equilateral hexagon cross-section, which can also abut against the inner wall of the sewer pipe to play a guiding role, and can further improve the stability of the positioning frame 1 during movement, and further reduce the situation where the positioning frame 1 is stuck in the sewer pipe due to offset.

[0038] A sewer pipe repair method is also provided, comprising the sewer pipe repair device described above, and adopting the following method: a. Put the repair device into the sewer, and control the repair device to move along the sewer pipe in the direction that needs to be cleaned; b. Start the circular blade 26 to cut the impurities on the wall of the sewer; c. Start the debris removal shovel 23 and the water spray gun to remove impurities on the sewer wall; d. Return the removal device to its original path and take out the repair device, spray the wall of the sewer with repair coating such as epoxy putty, waterproof glue and other repair liquids to form a smooth protective coating, thereby completing the repair of the sewer. During the specific implementation, it can be cleaned again when returning.

[0039] Working principle: first put the repair device into the sewer pipe, cut and clean the impurities attached to the inner wall of the sewer pipe, return the repair device to the original path after cleaning the impurities on the inner wall of the sewer pipe, and perform another cleaning at the same time. At this time, take out the repair device, and then send in the trolley for spraying the repair liquid. At this time, spray the repair liquid on the inner wall of the sewer pipe to repair the inner wall of the sewer pipe.

[0040] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
