In other embodiments, the conduit liner 110 may also include eight or ten liners, the particular number of which may be determined based on the shape and configuration of the conduit 400 to be repaired.
Moreover, since the pipe 400 to be repaired is generally a circular pipe, the lining plate is preferably an arc-shaped curved plate, and when the pipe lining 110 is unfolded to a supporting state, referring to fig. 9, the pipe lining 110 is cylindrical, so that the pipe lining 110 and the pipe 400 to be repaired can be better attached to each other, and the pipe lining 110 can firmly support the pipe 400 to be repaired. In other embodiments, the pipe 400 to be repaired may be a square pipe, an oval pipe, a hexagonal pipe, or the like, and the shape of the pipe liner 110 in the support state may be adapted to the shape of the pipe to be repaired.
In order to enable the adjacent liners to rotate relative to each other, as shown in fig. 5, the adjacent liners may be connected by a hinge 113, or may be connected by plastic ribs, or the like, so long as the adjacent liners can be converted between a relatively folded state and a mutually abutted state. The lining board can be stainless steel plate or other sectional materials such as PVC, so that the pipeline lining ring 110 in a supporting state has good strength, and the service life of the pipeline lining ring 110 is prolonged.

In addition, the male lock 114 and the female lock 116 are both arranged on the end surfaces of the lining boards, in order to improve the reliability of mutual butt joint between adjacent lining boards, as shown in fig. 6, a groove is formed in the male lock 114, a lubricating sealant 115 is injected into the groove, when the male lock 114 is inserted into the female lock 116, the lubricating sealant 115 can tightly bond the male lock 114 and the female lock 116, so that the adjacent lining boards are guaranteed to have better supporting and shaping effects, and the lubricating sealant 115 can also fill the female lock 116, so that gaps between the male lock 114 and the female lock 116 can be prevented, and further the condition of fluid leakage can be prevented. In a more preferred embodiment, the ends of the liners are further provided with sealing strips for sealing the gap between adjacent liners.
In addition, when the pipe lining 110 is in the contracted state, a setting tape is wound around the outside of the pipe lining 110 in order to enable the pipe lining 110 in the contracted state to be positioned and mounted on the driving mechanism. The contracted state of the pipe lining 110 is transferred to the deformed portion of the pipe 400 to be repaired, the pipe lining 110 is prevented from being detached from the driving mechanism by winding the setting tape, and the setting tape can be spread apart without affecting the state change of the pipe lining 110 when the driving mechanism drives the pipe lining 110 to the supporting state. Alternatively, in other embodiments, the contracted conduit liner 110 may be bonded to the drive mechanism, and the conduit liner 110 may be detached from the drive mechanism when the drive mechanism drives the conduit liner 110 to the supported state.
Further, the driving mechanism in the above-described embodiment may be of various forms, for example, a telescopic cylinder, a rack and pinion assembly, an inflatable balloon, or the like, as long as the force can be applied to the pipe liner 110 from the inside of the pipe liner 110. In a preferred embodiment, as shown in fig. 2 and 3, the driving mechanism includes a plurality of telescopic cylinders 120 supported within the pipe liner 110, the first ends of the plurality of telescopic cylinders 120 being fixed to each other and the second ends extending in different directions, and when the pipe liner 110 is in a contracted state, an end of at least one liner plate abuts against the second end of at least one telescopic cylinder 120. The plurality of telescopic cylinders 120 extending in different directions can drive the pipeline gasket 110 to be spread to a supporting state from a plurality of directions at the same time, and the pipeline gasket 110 can be ensured to be spread to a preset shape by applying force in the plurality of directions at the same time. The telescopic cylinder 120 may be a hydraulic cylinder, an air cylinder, or the like.
In the above embodiment, as shown in fig. 2, the number of the telescopic cylinders 120 is four, the four telescopic cylinders 120 are distributed in a cross shape, and the four telescopic cylinders 120 extend along the radial direction of the pipe lining 110, so that the stress of the pipe lining 110 is more balanced, and the pipe lining 110 is ensured to be capable of being stretched according to a predetermined shape. Such crisscross distributed telescopic cylinders 120 may also be referred to as jacks, and the force applied by the jacks may be transmitted to the pipe 400 to be repaired through the pipe collar 110, thereby helping to restore the deformed portion.
As shown in fig. 2 and 3, the telescopic cylinder 120 includes a cylinder body 121, a telescopic rod 122 slidable in the cylinder body 121, and an abutment block 123 provided on a free end of the telescopic rod 122, the abutment block 123 being capable of directly contacting an inner surface of the pipe liner 110 and expanding a contact area of the telescopic cylinder 120 and the pipe liner 110, so that the force applied by the telescopic cylinder 120 to the pipe liner 110 is more balanced. In other embodiments, the drive mechanism includes multiple sets of crisscrossed telescopic cylinders 120 spaced apart along the axial direction of the pipe collar 110. When the deformed portion of the pipe 400 to be repaired has a longer axial distance, the axial length of the pipe lining ring 110 is correspondingly longer, so that a plurality of groups of telescopic cylinders 120 distributed in a cross shape are required to apply a stretching driving force to the pipe lining ring 110, and the pipe lining ring 110 stretched to a predetermined shape can also better support and repair the deformed pipe 400 to be repaired.
In order to facilitate the transportation of the pipe lining 110 to a designated position within the pipe 400 to be repaired, as shown in fig. 3, the repair apparatus 100 further includes a traveling mechanism 130, the traveling mechanism 130 includes a traveling beam 131 and a plurality of traveling legs 132 supportable on an inner surface of the pipe 400 to be repaired, both ends of the traveling beam 131 are provided with the traveling legs 132, and a first end of the telescopic cylinder 120 is fixed to the traveling beam 131. The pipe collar 110 and the drive mechanism can be moved to the deformed position to be repaired by pulling the walking leg 132. In the above embodiment, the roller 133 is provided at one end of the travel leg 132 abutting against the inner surface of the pipe 400 to be repaired, so that the movement resistance of the travel mechanism 130 in the pipe 400 to be repaired can be reduced. Alternatively, in other embodiments, the running gear 130 may be of other forms, such as a running car having a plurality of wheels, or the like.
In addition, because the space in the pipe to be repaired is generally small, the operator cannot intuitively detect and monitor the working condition of the repairing device 100, and therefore, in a preferred embodiment, the repairing device 100 further includes a video collector (not shown) disposed on the walking beam 131, where the video collector may be preferably an infrared camera, which can complete the shooting task in a dim light environment. The image data captured by the video collector can be transmitted to a display device in the control room 200 on the ground, so that the operator can monitor in real time. Alternatively, as shown in fig. 1, the repairing device 100 may further include a video capture robot 300, where the video capture robot 300 can walk freely in the pipe 400 to be repaired to monitor the working condition of the repairing device 100, and the video capture equipment set on the video capture robot 30 may be an infrared camera as well.

and S3, after the supporting and fixing pieces on the adjacent lining plates are mutually fixedly matched, the driving mechanism is moved out of the pipeline 400 to be repaired.
Specifically, referring to fig. 1, the repair device 100 can be introduced into the pipe 400 to be repaired from the inspection well 500, and the traveling mechanism 130 is pulled by a rope extending from the control room 200 to travel to a deformed portion of the pipe 400 to be repaired. Then, the controller in the control room 200 controls the extension of the telescopic cylinder 120 to drive the pipe lining 110 to be opened from the contracted state to the supporting state, so that the pipe lining 110 is supported on the inner surface of the pipe 400 to be repaired. When the pipe lining 110 is spread, the male lock 114 on the end surface of the lining board is inserted into the female lock 116, so that the adjacent lining boards are locked and fixed with each other, and the pipe lining 110 is ensured to have enough supporting force, so that the deformed and collapsed position of the pipe 400 to be repaired is reset. Finally, the controller controls the telescopic cylinder 120 to shorten, the pipeline lining ring 110 is separated from the telescopic cylinder 120, and the travelling mechanism 130 and the telescopic cylinder 120 can be pulled out of the pipeline 400 to be repaired through ropes and pulled back to the ground through the inspection well 500.
