First connecting seat 21 and second connecting seat 22 all are cylindricly, and both all can arrange in the restoration pipe in, both all are connected with a set of restriction mechanism 3 (see fig. 2) of restricting its and restoration pipe position, and restriction mechanism 3 includes six can with the restriction piece 31 of restoration pipe inner wall butt, articulate the connecting rod 32 that is close to the 2 axes of drive mechanism in restriction piece 31, simultaneously with connecting rod 32 articulated connecting plate 33 and two electric push cylinders 34 that drive the connecting plate and remove. The end faces of the first connecting seat 21 and the second connecting seat 22 close to each other are all penetrated with mounting holes 24, and are all fixed with mounting plates 241 for sealing the mounting holes 24 by bolts. First connecting seat 21 and second connecting seat 22 all are the cavity setting, and both lateral walls all run through in the circumference has six grooves 23 that slide, and restriction piece 31 can be arranged in and slide in grooves 23, and the connecting plate slides in first connecting seat 21 or the inner chamber of second connecting seat 22, and its lateral wall and first connecting seat 21 or the inner wall butt of second connecting seat 22. The electric pushing cylinder 34 is fixed on the end face of the first connecting seat 21 or the second connecting seat 22, which is far away from the inner cavity, by using a bolt, the piston rod of the electric pushing cylinder is abutted against the end face of the connecting plate 33, and the connecting rod 32 is hinged on the end face of the connecting plate, which is far away from the electric pushing cylinder 34. The end faces, close to each other, of the two mounting plates 241 are connected with a traction rope 25, the electric pushing cylinders 34 are connected with a controller 11 for controlling the start and stop of the electric pushing cylinders, and the controller 11 is connected with the electric pushing cylinders 34 in the first connecting seat 21 and the second connecting seat 22 through conducting wires. When a pipeline is repaired, a drill bit of a non-excavation drilling machine penetrates through the pipeline to be repaired, then the traction head 1 is connected with a rotating head of the non-excavation drilling machine, the first connecting seat 21 and the second connecting seat 22 are arranged in the repairing pipe and are respectively positioned at two ends of the repairing pipe, then the controller 11 is used for controlling a piston rod of the electric pushing cylinder 34 to extend, the limiting block 31 is abutted against the inner wall of the repairing pipe, at the moment, the non-excavation drilling machine is used for driving the repairing pipe to enter the pipeline to be repaired, whether the repairing pipe reaches a position to be repaired is determined according to the moving distance of the drill bit of the non-excavation drilling machine, when the repairing position is reached, the controller 11 controls the piston rod of the electric pushing cylinder 34 to contract, the limiting block 31 is separated from the connection with the repairing pipe, at the moment, the non-excavation drilling machine continues to move, the traction mechanism 2 is separated from the pipeline.

As shown in fig. 3, dirt remains on the inner wall of the unrepaired pipeline, and a force for blocking the movement of the repaired pipe is applied to the repaired pipe during the movement of the repaired pipe, so that the traction mechanism 2 is separated from the repaired pipe. Therefore, one end of the first connecting seat 21 close to the traction head 1 is in threaded sleeve connection with the cleaning ring 26, and the outer wall of the cleaning ring 26 is abutted with the inner wall of the unrepaired pipeline. The cleaning ring 26 is used for scraping off dirt on the inner wall of the pipeline which is not repaired, so that the dirt can not block the movement of the repaired pipe, and the connection between the traction mechanism 2 and the repaired pipe is more stable.

As shown in fig. 3, the cleaning ring 26 is disposed in the pipe to be repaired in a troublesome process because the outer wall of the cleaning ring 26 abuts against the inner wall of the pipe to be repaired. The cleaning ring 26 thus has a wedge surface 261 at its end face edge adjacent to the traction head 1, the end of the wedge surface 261 adjacent to the traction head 1 being inclined in the direction of the first connection socket 21. The use of wedge 261 reduces the area of the cleaning ring 26 at the opening to the pipe not being repaired, thereby making it easier for the cleaning ring 26 to be inserted into the pipe being repaired.

As shown in fig. 2, since the diameter of the pipeline to be repaired is changed, the diameter of the repair pipe is also changed, the shape of the end surface of the limiting block 31 away from the axis of the traction mechanism 2 is not changed, and the contact area between the limiting block 31 and the inner wall of the repair pipe is small, the connection strength between the limiting mechanism 3 and the repair pipe is low, and the movement of the repair pipe is affected. Therefore, the end faces, far away from the axis of the traction mechanism 2, of the limiting blocks 31 are all adhered with flexible pads 35, and the flexible pads 35 are made of rubber. When the restricting block 31 moves toward the inner wall of the repair tube, the restricting block 31 deforms the flexible pad 35 so that the flexible pad 35 can abut against the inner wall of the repair tube, and at this time, the frictional force between the restricting block 31 and the repair tube is increased, thereby increasing the stability of the restricting mechanism 3 during use.

As shown in fig. 4, since the degree of damage in the pipe is different, the length of the repair pipe required at this time is also different, and the interval between the first and second connection seats 21 and 22 needs to be changed. Therefore, the end surface of the second connecting seat 22 far from the first connecting seat 21 is connected with the fastening mechanism 4, and the fastening mechanism 4 comprises a fixing block 41 welded to the end surface of the second connecting seat 22, a fastening block 42 for clamping the traction rope 25 and two fastening bolts 43 for driving the fastening block 42 to move. The fastening block 42 and the fixed block 41 can clamp the traction rope 25 together, and the fastening bolt 43 penetrates through the fastening block 42 and is in threaded connection with the fixed block 41. The end face of the second connecting seat 22 coaxially penetrates through a yielding groove 221, the mounting plate 241 connected with the second connecting seat 22 penetrates through the yielding groove 221, and the traction rope 25 penetrates through the yielding groove 221 and is arranged between the fixing block 41 and the fastening block 42. After the length of the repair tube to be moved is changed, the distance between the first and

second coupling sockets

21 and 22 is adjusted, and then the relative position of the traction rope 25 and the second coupling socket 22 is fixed by the fastening mechanism 4, at which time the repair tube after the length change can be driven.

In order to increase the connection strength between the fastening block 42, the fixing block 41 and the pulling rope 25 and to prevent the relative position between the pulling rope 25 and the second connecting seat 22 from changing, as shown in fig. 4, a plurality of fastening strips 421 are integrally formed on the end surface of the fastening block 42 close to the fixing block 41, a plurality of fixing strips 411 are integrally formed on the end surface of the fixing block 41 close to the fastening block 42, and the fastening strips 421 and the fixing strips 411 are perpendicular to the axis of the second connecting seat 22. Utilize fastening strip 421 and fixed strip 411 to make haulage rope 25 produce slight deformation, increased the area of contact between haulage rope 25 and fastening block 42 and the fixed block 41 this moment, increased the frictional force between the three, make the difficult emergence of position between haulage rope 25 and the second connecting seat 22 change.

As shown in fig. 3, since the cleaning ring 26 is screwed with the first connection seat 21, when a force is applied by dirt in a direction away from the traction head 1, the cleaning ring 26 rotates to move in a direction toward the repair pipe, so that the cleaning ring abuts against the repair pipe to affect the connection strength between the limiting mechanism 3 and the repair pipe. Therefore, the first connecting seat 21 is coaxially welded with the baffle ring 211, one end of the baffle ring 211, which is close to the traction head 1, can be abutted against the end face of the cleaning ring 26, the position of the cleaning ring 26 is limited by the baffle ring 211, so that the repair pipe cannot be abutted against the repair pipe to separate from the limiting mechanism 3, and the stability of the limiting mechanism 3 in use is improved.

In order to facilitate the use of the fastening bolt 43, as shown in fig. 4, a rotating block 431 is welded to the head of the fastening bolt 43, and the fastening bolt 43 is rotated by the rotating block 431, so that a tool is not required to be used when the fastening bolt 43 is used, thereby facilitating the use of the fastening mechanism 4.

The working principle is as follows:

when repairing a pipeline, firstly, a drill bit of a non-excavation drilling machine penetrates through the pipeline to be repaired, then a traction head 1 is connected with a rotating head of the non-excavation drilling machine, a traction mechanism 2 is arranged in the repair pipe, a first connecting seat 21 and a second connecting seat 22 are respectively positioned at two ends of the repair pipe, then a controller 11 is used for controlling a piston rod of an electric pushing cylinder 34 to move, so that a limiting block 31 is driven to abut against the inner wall of the repair pipe, then a traction rope 25 is pulled to keep tight, a fastening bolt 43 is rotated to drive a fastening block 42 to move towards a fixing block 41, the fastening block 42 and the fixing block 41 jointly clamp the traction rope 25, then the non-excavation drilling machine is started, the repair pipe is driven by the non-excavation drilling machine to enter the pipeline, the position of the repair pipe is determined according to the moving position of the drill bit of the non-excavation drilling machine, when the repair pipe is positioned at the damaged position of the pipeline, the controller 11 controls, thereby disconnecting the restricting block 31 from the repair tube, at which time the repair of the damaged pipe is completed.
