Description

Technical Field

[0001] This invention belongs to the technical field of pipeline repair, and in particular relates to an integrated curing device for pipeline repair using an airbag and ultraviolet lamp. Background Technology

[0002] In the field of trenchless pipeline repair, especially for the lining repair of underground pipelines such as drainage pipelines and gas pipelines, ultraviolet curing repair technology is widely used due to its advantages such as fast construction speed and strong environmental adaptability. This technology usually requires attaching the lining material impregnated with light-curing resin to the inner wall of the pipeline, and then using ultraviolet light to irradiate it to cure it. In order to achieve effective adhesion between the ultraviolet light and the inner wall of the pipeline and the movement and positioning of the device in the pipeline, existing repair devices often adopt independent airbag support mechanism and ultraviolet light irradiation mechanism, and cooperate with external traction or manual pushing to complete the movement of the device in the pipeline.

[0003] Existing pipeline repair equipment typically uses separate components for the airbag support device and the UV curing device during the repair and curing process. This requires multiple insertions into the pipeline, first using the airbag to expand the lining material, then replacing or inserting the UV lamp for curing, sometimes necessitating repeated operations. This results in a complex repair process, long operation time, and reduced construction efficiency. To address these issues, we provide an integrated airbag and UV lamp curing device for pipeline repair. Summary of the Invention

[0005] To solve the above technical problems, the present invention is achieved through the following technical solution: The present invention is an integrated curing device for pipeline repair using airbag and ultraviolet lamp, including a movable curing and repair component. The curing and repair component includes several radially movable limiting support plates. A curing airbag is provided on one side of the limiting support plate, and several flexible ultraviolet lamp strips are fixedly connected to the periphery of the curing airbag. A movable support component is fixedly provided on one side of the curing and repair component. The movable support component includes several movable support rods, and a movable wheel is rotatably provided at one end of each movable support rod. The movable support component is provided with a movable adjustment mechanism on one side. The movable adjustment mechanism consists of two symmetrically arranged movable adjustment components. A movable cable is provided between the two movable adjustment components. One end of the movable cable is fixedly connected to the movable support component. The movable adjustment component includes a tapered adjustment tube that can move horizontally back and forth. Several radially movable limit transmission guide rods are provided inside the tapered adjustment tube.

[0006] The present invention is further configured such that the curing repair component also includes a fixedly disposed hollow support column, one side of which is rotatably connected to a transmission external threaded pipe, and the peripheral side of the transmission external threaded pipe is provided with an adjustable internal threaded ring, and the adjustable internal threaded ring and the transmission external threaded pipe are threadedly engaged.

[0007] The hollow support column has several limiting transmission rods rotatably connected to its circumferential side via a first ear plate. The adjusting internal thread ring has a limiting drive rod corresponding to each limiting transmission rod rotatably connected to its circumferential side via a second ear plate. One end of the limiting drive rod is rotatably connected to the corresponding limiting transmission rod, and the limiting support plate is connected to one end of the corresponding limiting transmission rod. Several transmission brackets are fixedly connected to the circumferential side of the hollow support column.

[0008] The present invention is further configured such that the movable support assembly includes a fixedly disposed hollow support frame, the transmission bracket is fixedly connected to the hollow support frame, a first bevel gear is rotatably disposed inside the hollow support frame, and the first bevel gear is fixedly connected to the transmission external threaded pipe.

[0009] A second bevel gear is rotatably mounted inside the hollow support frame, and a drive bevel gear is rotatably connected to the inner wall of the hollow support frame. The drive bevel gear meshes with the first bevel gear and the second bevel gear.

[0010] The invention is further configured such that an adjustment support ring is fixedly connected to one side of the second bevel gear, and the surface of the adjustment support ring is provided with an arc-shaped transmission slide corresponding to the movable support link; one end of the movable support link that slides through the hollow support frame is fixedly connected to a transmission crossbar through a transmission slider, and the transmission crossbar slides in cooperation with the corresponding arc-shaped transmission slide.

[0011] The invention is further configured such that the movable adjustment component includes a hollow transmission frame sleeved on the periphery of the movable cable, the surface of the hollow transmission frame having a plurality of limiting holes, the limiting transmission guide rod being slidably disposed inside the corresponding limiting hole, the periphery of the limiting transmission guide rod being fixedly connected to a limiting disk, a return spring being fixedly connected between the limiting disk and the hollow transmission frame, and the inner wall of the tapered control tube having an inclined sliding surface structure, and the tapered control tube and the end of the limiting transmission guide rod being in sliding engagement.

[0012] A support column is fixedly connected to the periphery of the tapered control tube. One end of the support column is rotatably connected to a control rod. One end of the control rod is rotatably connected to a drive disk. The control rod is rotatably connected to an eccentric position of the drive disk.

[0013] The present invention has the following beneficial effects: 1. By setting up a curing repair component, the present invention integrates the curing airbag and the flexible ultraviolet lamp strip into the same curing repair component, and with the radially movable limiting support plate, the device positioning, airbag support and ultraviolet curing operations can be completed in one go. There is no need to send different components such as independent airbags and ultraviolet lamps into the pipeline multiple times, which reduces the cumbersome steps of alternating equipment operation, significantly simplifies the repair process and improves the work efficiency.

[0014] 2. This invention, by setting up a curing and repair component and a moving support component, utilizes the meshing transmission of the first and second bevel gears and the driving bevel gear in the moving support component, combined with the sliding cooperation of the arc-shaped transmission slide on the control support ring and the transmission crossbar, to simultaneously realize the radial extension and retraction of the limiting support plate to fit against the inner wall of the pipe for positioning, and the radial extension and retraction of the moving support connecting rod to retract and extend the moving wheels. This reduces the need for additional power sources, making the switching between the working support state and the moving walking state of the device simpler and more synchronous. The overall structure is compact, with high control precision and good reliability.

[0015] 3. This invention incorporates a movable adjustment component. Within this component, a drive disc and a control linkage propel a tapered control tube to move horizontally back and forth. Utilizing the cooperation between the inclined sliding surface inside the tapered tube and the limiting transmission guide rod, the moving cable is periodically clamped and released. During the clamping phase, the moving cable is pulled to move the entire device. During the release phase, the adjustment component resets, thus forming a stable step-by-step movement. This allows the device to be controlled to gradually advance to the repair position within the pipeline, ensuring smooth movement and accurate positioning. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For a specific implementation example, please refer to Implementation Example 1. Figure 1-8 The present invention is an integrated curing device for pipeline repair using airbag and ultraviolet lamp, including a movable curing and repair component 1. Specifically, the curing and repair component 1 includes several radially movable limiting support plates 101. A curing airbag 102 is provided on one side of the limiting support plate 101, and several flexible ultraviolet lamp strips 103 are fixedly connected to the periphery of the curing airbag 102. Furthermore, a movable support component 2 is fixedly provided on one side of the curing and repair component 1. The movable support component 2 includes several movable support rods 201 that can move. One end of each movable support rod 201 is rotatably provided with a movable wheel 202. Furthermore, a movable adjustment mechanism is provided on one side of the movable support component 2. The movable adjustment mechanism consists of two symmetrically arranged movable adjustment components 3. A movable cable 4 is provided between the two movable adjustment components 3. One end of the movable cable 4 is fixedly connected to the movable support component 2. The movable adjustment component 3 includes a tapered control tube 301 that can move horizontally back and forth. Several radially movable limit transmission guide rods 302 are provided inside the tapered control tube 301.

[0028] The operation process of this embodiment is as follows: The entire device is sent into the pipe to be repaired through the pipe inlet. The corresponding moving adjustment component 3 is activated, causing the corresponding conical control tube 301 to move horizontally back and forth. The limiting transmission guide rod 302 moves radially in sync to clamp and limit the moving cable 4. Then, under the limiting action of the limiting transmission guide rod 302, the moving cable 4 is pulled, causing the moving wheel 202 to move along the inside of the pipe, driving the curing repair component 1 to move axially along the pipe to the position to be repaired. Then, the limiting support plate 101 is controlled to move radially outward, while the moving support connecting rod 201 moves in the opposite direction, and the moving wheel 202 retracts until the limiting support plate 101 and the pipe are aligned. The device is positioned to fit snugly against the inner wall of the pipe. The curing airbag 102 is then expanded, allowing the flexible ultraviolet lamp strip 103 to adhere to the inner wall of the pipe to be repaired. The flexible ultraviolet lamp strip 103 is then activated to perform ultraviolet curing on the lining material of the area to be repaired. After curing, the limiting support plate 101 is retracted, reducing the overall outer diameter of the curing airbag 102. Simultaneously, the support connecting rod 201 is moved radially until the moving wheel 202 is in contact with the inner wall of the pipe. Pulling the moving cable 4 allows the entire device to be removed from the pipe. This device integrates airbag support and ultraviolet curing functions, eliminating the need for multiple insertions of different working components, simplifying the pipe repair process and improving repair efficiency.

[0029] For a specific embodiment two, please refer to Figure 1-8 Based on the specific embodiment 1, specifically, the curing repair component 1 also includes a fixedly installed hollow support column 104, one side of which is rotatably connected to a transmission external threaded pipe 105, and the peripheral side of the transmission external threaded pipe 105 is provided with an adjustment internal threaded ring 106, and the adjustment internal threaded ring 106 and the transmission external threaded pipe 105 are threadedly engaged.

[0030] Furthermore, the hollow support column 104 has several limiting transmission rods 107 rotatably connected to its circumferential side via a first ear plate, and the adjusting internal thread ring 106 has limiting drive rods 108 corresponding to the limiting transmission rods 107 rotatably connected to its circumferential side via a second ear plate. One end of the limiting drive rod 108 is rotatably connected to the corresponding limiting transmission rod 107, and the limiting support plate 101 is connected to one end of the corresponding limiting transmission rod 107. Several transmission brackets are fixedly connected to the circumferential side of the hollow support column 104.

[0031] Furthermore, the movable support assembly 2 also includes a fixedly installed hollow support frame 203, a transmission bracket fixedly connected to the hollow support frame 203, a first bevel gear 204 rotatably installed inside the hollow support frame 203, the first bevel gear 204 being fixedly connected to the transmission external threaded pipe 105; a second bevel gear 205 rotatably installed inside the hollow support frame 203, a drive bevel gear 206 rotatably connected to the inner wall of the hollow support frame 203, a drive motor fixedly installed on the periphery of the hollow support frame 203 via a motor mount, the output shaft of the drive motor being fixedly connected to the drive bevel gear 206, and the drive bevel gear 206 meshing with the first bevel gear 204 and the second bevel gear 205.

[0032] The second bevel gear 205 is fixedly connected to one side of an adjustment support ring 207. The surface of the adjustment support ring 207 is provided with an arc-shaped transmission slide 208 that corresponds one-to-one with the movable support link 201. One end of the movable support link 201 slides through the hollow support frame 203 and is fixedly connected to a transmission crossbar 209 through a transmission slider. The transmission crossbar 209 and the corresponding arc-shaped transmission slide 208 slide in a sliding fit.

[0033] Furthermore, the movable adjustment component 3 includes a hollow transmission frame 303 sleeved on the periphery of the movable cable 4. The surface of the hollow transmission frame 303 has several limiting ports. The limiting transmission guide rod 302 is slidably disposed inside the corresponding limiting port. A limiting disc is fixedly connected to the periphery of the limiting transmission guide rod 302. A return spring is fixedly connected between the limiting disc and the hollow transmission frame 303. The inner wall of the tapered control tube 301 is an inclined sliding surface structure. The tapered control tube 301 and the end of the limiting transmission guide rod 302 are in sliding engagement.

[0034] A support column is fixedly connected to the periphery of the tapered control tube 301. A control rod 304 is rotatably connected to one end of the support column. A drive disc 305 is rotatably connected to one end of the control rod 304. The drive disc 305 is fixedly connected to the external support frame. A control motor is fixedly installed on one side of the external support frame. The output shaft of the control motor is fixedly connected to the corresponding drive disc 305. The control rod 304 is rotatably connected to the eccentric position of the drive disc 305.

[0035] The operation process of this embodiment is as follows: When repairing the pipeline, the entire device is inserted into the pipeline to be repaired through the pipeline inlet. The corresponding control motor is started to drive the corresponding drive disc 305 to rotate. After the drive disc 305 rotates, the eccentrically set control rod 304 pulls the conical control tube 301 to move horizontally back and forth. During the reciprocating movement of the conical control tube 301, the limiting transmission guide rod 302 is forced to move radially periodically by the compression of the inclined sliding surface. When the conical control tube 301 moves forward, the limiting transmission guide rod 302 moves radially closer to the conical control tube 301. When the axis is in place, the moving cable 4 is clamped and restricted, and then the moving cable 4 is periodically clamped. Under the clamping restriction of the limiting transmission guide rod 302, when the tapered control tube 301 moves in the opposite direction, the limiting transmission guide rod 302 gradually moves away from the axis, releasing the clamping restriction on the moving cable 4. Only the tapered control tube 301 and the hollow transmission frame 303 move in the opposite direction, and then the moving cable 4 is pulled to drive the moving support component 2 to move. The moving wheel 202 moves along the inside of the pipe, driving the curing repair component 1 to move synchronously along the axial direction of the pipe to the position to be repaired.

[0036] The drive motor is restarted, driving the drive bevel gear 206 to rotate. Under the meshing action of the drive bevel gear 206 with the first bevel gear 204 and the second bevel gear 205, the first bevel gear 204 and the second bevel gear 205 rotate synchronously in opposite directions. After the first bevel gear 204 rotates, it drives the transmission external threaded pipe 105 to rotate synchronously. After the transmission external threaded pipe 105 rotates, it drives the regulating internal threaded ring 105 to move axially through the thread action. After the regulating internal threaded ring 105 moves axially, it pushes the limiting transmission rod 107 to open outward through the limiting drive rod 108, thereby driving the limiting support plate 101 to move radially outward to fit against the inner wall of the pipe. When the second bevel gear 205 rotates, the second bevel gear... 205 drives the control support ring 207 to rotate synchronously. After the control support ring 207 rotates, it drives the moving support connecting rod 201 to retract inward through the sliding cooperation between the arc-shaped transmission slide 208 and the transmission crossbar 209. This, in turn, drives the moving wheel 202 to retract inward synchronously, completing the switch of the support position. Then, the curing airbag 102 is opened, so that the flexible ultraviolet lamp strip 103 fits against the inner wall of the pipe to be repaired. The flexible ultraviolet lamp strip 103 is started to perform ultraviolet curing on the lining material of the part to be repaired. When it is necessary to retract the device, the drive bevel gear 206 can be rotated in the opposite direction to complete the retraction of the limit support plate and the extension of the moving wheel synchronously. This allows the support switching and position adjustment of the device to be completed synchronously with only a single power source.
