TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe lining inversion repair, in particular to a pipe lining inversion repair device. BACKGROUND

[0002] The pipe lining inversion repair technology is to use a felt-made hose immersed in thermosetting resin as the inversion material, and to use the old pipe to be repaired as the inversion channel after cleaning. During the repair construction, the inversion material is first wound on the winding roller of the inversion conveying device, then the free end of the inversion material is passed out of the air outlet of the inversion conveying device, and the end is reversely sleeved on the air outlet, and then the end of the inversion material is fixed on the air outlet through the throat clamp. Then, high-pressure gas is passed into the inversion conveying device, and the hose is reversely turned into the inner wall of the pipe under the action of gas pressure and tightly advances along the inner wall of the pipe until the hose penetrates through the entire pipe and extends out of the other end. After the felt-made hose immersed in thermosetting resin is cured and formed, a new steel pipe is formed. The new and old pipes jointly bear pressure, thereby completing the repair of the old pipe.

[0003] At present, in the process of repairing the inside of the old pipe by the pipe lining inversion repair technology, the adaptability between the hose and the joint is poor, so that after the throat clamp is tightened around the end of the hose, wrinkles are easily formed on the end of the hose, the hose and the air outlet cannot form a good seal, the high-pressure gas easily leaks out through the channel formed by the wrinkles during the conveying of the hose by the gas pressure, the gas pressure in the hose fluctuates, the hose is difficult to tightly adhere to the inner wall of the old pipe during the conveying process, and there are gaps between the hose as the lining layer and the inner wall of the old pipe. These gaps may become leakage channels for the gas or liquid conveyed in the pipe in the future, thereby damaging the sealing performance of the repaired pipe and affecting the repair effect of the pipe.

[0017] 2. The hose end is reversely sleeved on the cylindrical outlet pipe and the tapered connecting pipe in the port assembly, the part of the hose end reversely sleeved on the cylindrical outlet pipe is tightened by the throat clamp, and then the position of the execution structure is adjusted by the rotating adjusting screw, so that before high-pressure gas is injected into the hose, the position of the execution structure can be adjusted according to the position of the hose reversely sleeved outside the tapered connecting pipe, thereby facilitating people to fix the end of the hose reversely sleeved on the cylindrical outlet pipe and the tapered connecting pipe.

[0034] Embodiment 1: Reference Figure 1 , Figure 2 , Figure 4 and Figure 6 The embodiments of the present application provide a pipe lining turnover repair device, which comprises a turnover conveying structure and a port assembly arranged at an air outlet of the turnover conveying structure. The port assembly comprises a throat clamp 203, a flexible pressing structure and a conical connecting pipe 205 in the shape of a circular truncated cone, and the narrow end of the conical connecting pipe 205 is connected with a cylindrical outlet pipe 202. The flexible pressure covering structure comprises a flow guide hose 204, an adjusting structure, and an executing structure arranged around the outer periphery of the conical connecting pipe 205. The adjusting structure is connected between the turnover conveying structure and the executing structure, and is used to adjust the relative position between the executing structure and the conical connecting pipe 205. The executing structure comprises a ring-shaped base 201 with a circular truncated cone-shaped inner cavity, and the generatrix of the circular truncated cone-shaped inner cavity of the ring-shaped base 201 is parallel to the generatrix of the curved surface of the outer wall of the conical connecting pipe 205. A ring of air cavity grooves is arranged around the side wall of the inner cavity of the ring-shaped base 201. Ring-shaped elastic capsule units are connected to the side wall of the inner cavity of the ring-shaped base 201 at positions corresponding to the air cavity grooves. The flow guide hose 204 is connected between the turnover conveying structure and the executing structure.

[0035] Referring to Figures 2 to 4 , Figures 6 to 10 The ring-shaped elastic capsule units comprise ring-shaped elastic capsules 211 and ring-shaped flexible limiting covers 208 connected to the side wall of the inner cavity of the ring-shaped base 201. The ring-shaped elastic capsules 211 are located in the inner cavities of the ring-shaped flexible limiting covers 208. The ring-shaped flexible limiting covers 208 are preferably made of high-strength fiber fabric material. The ring-shaped elastic capsules 211 are arranged to cover the end openings of the air cavity grooves. When the ring-shaped elastic capsules 211 are in an initial state, the inner cavities of the ring-shaped elastic capsules 211 are circular truncated cone-shaped, and the generatrix of the circular truncated cone-shaped inner cavities of the ring-shaped elastic capsules 211 is parallel to the generatrix of the curved surface of the outer wall of the conical connecting pipe 205.

[0036] The central axis of the circular truncated cone-shaped inner cavity of the ring-shaped base 201 is collinear with the central axis of the conical connecting pipe 205. The central axis of the circular truncated cone-shaped inner cavity of the ring-shaped elastic capsules 211 is also collinear with the central axis of the conical connecting pipe 205.

[0037] After the felt hose soaked with thermosetting resin and wound inside the turnover conveying structure is passed through the cylindrical outlet pipe 202 in the port assembly, the end of the hose is reversely sleeved on the cylindrical outlet pipe 202 in the port assembly and the conical connecting pipe 205. After the part of the hose end reversely sleeved on the cylindrical outlet pipe 202 is clamped by the throat clamp 203, the hose end is gradually expanded by the conical connecting pipe 205 with a circular truncated cone shape. Then, high-pressure gas is injected into the inside of the turnover conveying structure. During the process that the high-pressure gas pushes the hose to gradually extend out of the inside of the port assembly, the high-pressure gas used for conveying the hose is also continuously injected into the inner cavities of the ring-shaped elastic capsules 211 of the executing structure, so that the ring-shaped elastic capsules 211 are elastically deformed and gradually expanded in volume and tightly press against the surface of the hose expanded by the conical connecting pipe 205, so that the expanded hose is tightly attached to the surface of the conical connecting pipe 205. Thus, on the basis of the hose fixed by the throat clamp 203, an additional sealing barrier is formed, thereby effectively reducing the risk of leakage caused by the wrinkles of the hose during the process of conveying the hose into the old pipeline, and improving the repair effect of the pipeline.

[0038] When the inner diameter size of the hose is the same as or similar to the outer diameter size of the cylindrical outlet pipe 202 in the port assembly, so that the hose is less wrinkled after being sleeved on the cylindrical outlet pipe 202, and the reversed hose is difficult to be sleeved on the conical connecting pipe 205, the hose does not need to be sleeved on the conical connecting pipe 205, and after the reversed hose is fixed on the cylindrical outlet pipe 202 by the grommet 203, the high-pressure gas can be injected into the inversion conveying structure, and the felt hose soaked with the thermosetting resin can be conveyed into the old pipeline by the high-pressure gas.

[0039] With reference to Figure 2 , Figure 4 and Figure 6 , the embodiment of the present application provides a pipeline lining inversion repair device, and the adjusting structure comprises an adjusting screw 207 arranged in an inclined manner.

The adjusting screw 207 and the guide column are parallel to the central axis of the conical connecting pipe 205.

[0040] The end of the hose is reversely sleeved on the cylindrical outlet pipe 202 and the conical connecting pipe 205 in the port assembly, the part of the end of the hose reversely sleeved on the cylindrical outlet pipe 202 is clamped by the grommet 203, and then the position of the executing structure is adjusted by rotating the adjusting screw 207, so that before the high-pressure gas is injected into the hose, the position of the executing structure can be adjusted according to the position of the hose reversely sleeved on the conical connecting pipe 205, thereby facilitating the fixing treatment of the end of the hose reversely sleeved on the cylindrical outlet pipe 202 and the conical connecting pipe 205.

The gas collecting cover 105 is fixedly connected to the inversion shell 101, one end of the flow guide hose 204 is fixedly connected to the side wall of the gas collecting cover 105 in the inversion conveying structure, and the other end is connected to the annular base 201, and the inner cavity of the flow guide hose 204 is connected to the air cavity groove in the annular base 201.

[0042] After the felt hose soaked in thermosetting resin is wound on the winding roller in the flip shell 101, the end of the hose is then inserted through the cylindrical outlet pipe 202 in the port assembly, and the end of the hose is reversely sleeved on the cylindrical outlet pipe 202 and the conical connecting pipe 205 in the port assembly. Then, the sealing door plate 103 is sealed and covered on the end opening of the entrance, and the sealing door plate 103 is detachably fixed on the side wall of the flip shell 101 by bolt connection or buckle connection. The external gas injection pipeline is connected to the end of the injection entrance 102, and then high-pressure gas is continuously injected into the inside of the flip shell 101 in the flip conveying structure through the external gas injection pipeline.

[0043] In example 2, the difference from example 1 is that Figures 2 to 4 , Figure 8 , Figure 10 The pipe lining flip repair device provided by the embodiment of the application is further provided with an internal pressure sensing unit on the annular base 201. The internal pressure sensing unit comprises an insulating cover 209 which is sealingly connected to the side wall of the annular base 201 and of which the inner cavity is in communication with the gas cavity groove. The insulating cover 209 is connected with an indicating lamp 210. The insulating cover 209 is further provided with an insulating piston seat 213, an elastic element, and a passive switch spring 216 and a static switch terminal 217 which are oppositely arranged in the inner cavity of the insulating cover 209. The insulating piston seat 213 is sealingly and slidably arranged in the inner cavity of the insulating cover 209, and the elastic element is connected in the inner cavity of the insulating cover 209 and the free end of the elastic element is connected with the insulating piston seat 213. The passive switch spring 216 is connected with the insulating piston seat 213, and the static switch terminal 217 is connected in the inner cavity of the insulating cover 209. When the gas pressure value in the gas cavity groove reaches the preset range, the passive switch spring 216 moves towards the static switch terminal 217 in the process of driving the elastic element to elastically extend by the gas pressure, and when the passive switch spring 216 contacts with the static switch terminal 217, the indicating lamp 210 is triggered to be turned on.

[0044] Referring to Figure 8 and Figure 10The embodiment of the present application provides a pipeline lining turnover repair device, the elastic element comprises an inner connecting frame 212 connected in the inner cavity of the insulating cover 209, a directional plug 215 is slidably inserted into the end of the inner connecting frame 212; The directional plug 215 is sleeved with a telescopic spring 214, one end of the telescopic spring 214 is connected with the end of the inner cavity of the inner connecting frame 212, and the other end is connected with the end of the insulating piston seat 213; The passive switch spring 216 is connected to the end of the insulating piston seat 213 away from the telescopic spring 214; One end of the directional plug 215 extends into the inner cavity of the inner connecting frame 212 and is connected with the end of the insulating piston seat 213, and the other end extends out of the end of the inner connecting frame 212 and is connected with a limiting seat; When the air pressure value in the air cavity groove reaches the preset range, the air pressure drives the telescopic spring 214 in the elastic element to elastically elongate through the insulating piston seat 213.

[0045] High-pressure gas is injected into the inside of the turnover conveying structure, and in the process that the high-pressure gas pushes the hose to gradually extend out of the inside of the port assembly, the high-pressure gas is continuously injected into the inside of the annular elastic capsule 211 of the execution structure through the flow guide hose 204, when the air pressure in the inside of the annular elastic capsule 211 is in a set range, the air pressure pushes the insulating piston seat 213 to move, the moving insulating piston seat 213 not only pulls the telescopic spring 214 to elastically stretch, but also drives the passive switch spring 216 to move towards the static switch terminal 217, and when the passive switch spring 216 contacts the static switch terminal 217, the trigger schematic lamp 210 is triggered to turn on, reminding the staff that the air pressure in the annular elastic capsule 211 has reached the preset range, so that the annular elastic capsule 211 elastically expanded is tightly pressed on the surface of the hose expanded by the conical connecting pipe 205, guaranteeing that the execution structure has the compaction sealing effect on the hose end portion reversely sleeved outside the conical connecting pipe 205, and reminding the operator to further inject high-pressure gas into the inside of the turnover conveying structure, so that the air pressure in the turnover conveying structure reaches the conveying air pressure value.

[0046] When the air pressure in the annular elastic capsule 211 has reached the preset range and triggered the trigger schematic lamp 210 to turn on, and further injects high-pressure gas into the inside of the turnover conveying structure, the volume of the annular elastic capsule 211 elastically expanded is limited by the annular flexible limiting cover 208 of flexible inelastic material located outside the annular elastic capsule 211, so that the annular elastic capsule 211 is prevented from being broken due to excessive expansion, thereby affecting the compaction sealing effect of the execution structure on the hose end portion reversely sleeved outside the conical connecting pipe 205.
