A pipeline repairing and bonding device is shown in figure 1 and comprises a traction head 1 connected with a non-excavation drilling machine, wherein the side of the traction head 1 is in a bullet shape. The end face of the traction head 1 is connected with a connecting rod 11 through a bolt, one end, far away from the traction head 1, of the connecting rod 11 is connected with a traction mechanism 2 for driving the repair pipe to move, and the traction mechanism 2 comprises a traction seat 21 and a retaining ring 22 for limiting the position of the repair pipe. The traction seat 21 is connected to one end of the traction head 1 of the principle of the connecting rod 11, the baffle ring 22 is welded to one end of the traction seat 21, which is far away from the connecting rod 11, one end of the baffle ring, which is close to the connecting rod 11, can be abutted against the repair pipe, a gap is left between the end face, which is far away from the axis of the traction seat 21, of the baffle ring and the inner wall of the pipeline to be repaired, and the traction seat 21 can be arranged. After repairing, a drill bit of the trenchless drilling machine penetrates through a pipeline to be repaired, then the repairing pipe is sleeved on the traction seat 21, then the traction head 1 is connected with the trenchless drilling machine, the trenchless drilling machine is used for driving the repairing pipe to move, whether the repairing pipe reaches a position to be repaired is determined according to the moving distance of the drill bit, then the drill bit moves towards the opposite direction, the traction mechanism 2 is separated from the drill bit, then the drill bit is separated from the pipeline from the other direction, and the pipeline repairing is completed.

As shown in fig. 2, since sewage passes through the pipeline, the flowing sewage exerts a force on the repair pipe along the axial direction thereof, so that the repair pipe moves, and the damage cannot be filled. Therefore, two groups of gluing mechanisms 3 are connected to the traction base 21, and each gluing mechanism 3 comprises a glue storage barrel 31, a pressure plate 32 sliding in the glue storage barrel 31 and an electric push rod 33 driving the pressure plate 32 to move. The traction seat 21 is hollow, the two ends of the traction seat are both penetrated with mounting holes 211, and the mounting holes are internally connected with a mounting plate 212 which is sealed by bolts. The middle part of the inner cavity of the traction seat 21 is welded with a fixed block 213, the bonding mechanisms 3 are respectively positioned at two sides of the fixed block 213, and the electric push rod 33 is fixed on the end surface of the fixed block 213 by using bolts. The glue storage barrel 31 is fixed in the traction base 21 by using bolts, a maintenance hole 311 penetrates through the end surface of the glue storage barrel, which is far away from the electric push rod 33, and a maintenance plate 312 for sealing the maintenance hole 311 is connected by screw threads. The pressure plate 32 is arranged in the glue storage barrel 31 to slide, the push rod of the electric push rod 33 penetrates through the glue storage barrel 31 to be connected with the pressure plate 32 through a bolt, and glue is arranged at one end of the pressure plate 32 far away from the electric push rod 33. The lateral wall of the glue storage barrel 31 is circumferentially provided with eight glue outlet holes 313 communicated with the inner cavity of the glue storage barrel, the glue outlet holes 313 are internally provided with first one-way valves 34, and the first one-way valves 34 are communicated towards the outside of the glue storage barrel 31. Eight abdicating holes 214 are circumferentially penetrated through the two end faces of the inner wall space of the traction seat 21, and the axes of the glue outlet holes 313 are respectively superposed with the axis of one abdicating hole 214. The electric push rod 33 is connected with a controller 23 for controlling the positive and negative rotation of the motor thereof by using a lead wire together, and is also connected with a storage battery by using a lead wire together. When the repair pipe is moved to the damaged position of the pipeline, the controller 23 is used for controlling the push rod of the electric push rod 33 to extend, then the pressure plate 32 is used for enabling glue to overcome the pressure of the first one-way valve 34 and flow out of the glue storage barrel 31, the repair pipe is connected with the pipeline to be repaired through the glue, and the position between the repair pipe and the pipeline to be repaired cannot be changed.

As shown in fig. 1, since dirt adheres to the inner wall of the pipe to be repaired, when the pipe to be repaired is connected to the pipe to be repaired by glue, the glue cannot adhere to the surface of the pipe to be repaired, and the connection strength between the pipe to be repaired and the pipe to be repaired is reduced. Therefore, the end face of the traction seat 21 close to the traction head 1 is hinged with a plurality of cleaning blocks 24, the cleaning blocks 24 are arranged around the axis of the traction seat 21, the adjacent cleaning blocks 24 are abutted, and the cleaning blocks 24 are made of flexible materials.

The cleaning block 24 is utilized to scrape off dirt on the inner wall of the pipeline to be repaired, so that glue can be connected with the inner wall of the pipeline, and the connection strength between the repairing pipe and the pipeline is increased.

As shown in fig. 1, when the glue flows out of the abdicating hole 214, it moves downward under the action of gravity, which may result in that the glue cannot completely adhere the connection between the repair tube and the pipeline. Therefore, the end of the traction seat 21 far away from the traction head 1 is coaxially welded with a limiting ring 26, the outer wall of the limiting ring 26 can be abutted against the inner wall of the pipeline to be repaired, and the end face of the limiting ring 26 close to the baffle ring 22 can be welded with the baffle ring 22. The limiting ring 26 is used for limiting the flowing of the glue, so that the glue can be completely contacted with the repair pipe and the pipeline to be repaired, the gap between the repair pipe and the pipeline to be repaired can be completely bonded, the connection strength between the repair pipe and the pipeline to be repaired is increased, and the repair effect of the repair pipe is better.

In order to facilitate the process of adding glue into the glue storage barrel 31, the traction base 21 and the glue storage barrel 31 do not need to be disassembled. As shown in fig. 3, the sidewall of each of the two glue storage barrels 31 has a glue inlet 314 penetrating through the sidewall thereof, and the glue inlet 314 is provided with a second one-way valve 35 communicating with the inside of the glue storage barrel 31. The inner wall of the traction seat 21 is provided with a connecting hole 215 at the position close to the two ends, and the glue inlet 314 is connected with the connecting hole 215. Glue can be directly injected into the glue storage barrel 31 by utilizing the glue inlet 314 and the connecting hole 215, so that the traction seat 21 and the glue storage barrel 31 do not need to be disassembled, and the process of injecting the glue into the glue storage barrel 31 is more convenient.

As shown in fig. 1, when the traction base 21 is passed through the repair tube, the cleaning block 24 needs to be rotated in the axial direction of the traction base 21, and the number of the cleaning blocks 24 is large, so that it is troublesome to directly move the cleaning blocks 24. Therefore, the connecting rod 11 is connected with a driving ring 12 in a sliding way, a plurality of connecting ropes 13 are adhered to the outer wall of the driving ring 12, and one ends of the connecting ropes 13 far away from the driving ring 12 are respectively adhered with a cleaning block 24. When the traction base 21 passes through the repair tube, the driving ring 12 is moved away from the traction base 21, and the cleaning block 24 is simultaneously rotated toward the axis direction of the traction base 21, so that the moving process of the cleaning block 24 is more convenient.

Since the position of the drive ring 12 still needs to be manually defined when moving the drive ring 12 away from the fifth wheel 21. Therefore, the connecting rod 11 is screwed with the driving nut 14, and one end of the driving nut 14 far away from the traction base 21 can be abutted with the end face of the driving ring 12 close to the traction base 21. The drive ring 12 is restrained in position by the drive nut 14 so that manual restraint of the position of the drive ring 12 is no longer required when the fifth wheel 21 is passed through the repair tube, thereby facilitating the pipe repair process.

The working principle is as follows:

a drill bit of the trenchless drilling machine firstly extends out from the other end of a pipeline to be repaired, the driving ring 12 is moved towards the direction far away from the traction seat 21, the cleaning block 24 is moved towards the axis direction of the traction seat 21, then the traction seat 21 penetrates through the repairing pipe to be connected with the traction head 1 and the drill bit, and then the driving ring 12 is moved towards the traction seat 21, so that the end face of the cleaning block 24 is abutted to the traction seat 21. Then, the repairing pipe is moved to the position to be repaired by using a trenchless drilling machine, whether the repairing pipe reaches the position to be repaired is judged by using the moving distance of the drill bit, then the controller 23 is used for controlling the push rod of the electric push rod 33 to move, so that the glue enters the pipeline, the limiting ring 26 and the cleaning block 24 are used for limiting the flow of the glue, and the glue can completely adhere the connecting position of the repairing pipe and the pipeline. The drill bit then drives the pull socket 21 and the pull head 1 out of the opening into the pipe, and then if the pull head 1 is disconnected from the drill bit, the drill bit is disconnected from the other end of the pipe, at this time the pipe repair is completed.
