Description

Technical Field

[0001] The present invention relates to the technical field of pipeline repair, in particular to a device for repairing deformation of a water supply pipeline. Background Art

[0002] As an important part of urban infrastructure, water supply pipes are an important component for maintaining the daily operation of the city. Water supply pipes are usually buried underground. Therefore, most water supply pipes adopt composite pipes (such as adding stainless steel lining to the inner wall of the pipe to improve the waterproof ability, and spraying anti-corrosion coating on the outside of the pipe to improve the corrosion resistance) to adapt to the complex and changeable underground environment. Due to the distribution characteristics of the water supply pipe network, it is often deformed due to ground load, internal corrosion of the pipe and inadequate daily maintenance. The deformation of the water supply pipe leads to a reduction in daily water supply capacity, and continuous deformation is very likely to occur, causing complete blockage of the pipe. Therefore, when the water supply pipe is deformed, it needs to be repaired in time.

[0003] Chinese invention patent application CN113898815A discloses a trenchless device and method for repairing deformation and collapse of drainage pipes. When repairing deformation of the pipe, this type of device activates a multi-section telescopic cylinder to push a resin plate to the top of the pipe wall, and then heats and cures the resin plate. After the resin plate is cured on the pipe, the deformation repair of the next section is carried out, and the deformed and collapsed position of the pipe to be repaired is supported in sections, thereby achieving a full circle repair.

[0004] Chinese invention patent application CN109654327A discloses a trenchless pipeline repair device and its repair process. When this type of device presses to repair a deformed pipeline, it uses a driving component to drive the first repair component to expand outward, expanding the concave part of the inner wall of the pipeline. Then, the propulsion device drives the rear-end repair device forward to perform a secondary repair on the pipeline, repairing the area that was not fully repaired by the front-end repair device.

[0005] However, in the existing repair device for the deformed part of the pipeline, when repairing the deformed part of the pipeline, the pressure exerted by each repair component on the pipeline often maintains the internal support repair in a fixed position, so there are gaps between adjacent repair components. Since the pipeline has stress, it is easy for the pipeline to deform towards the unstressed part under the action of stress, resulting in its unstressed part, especially the gap between two adjacent repair components, which is often unable to be effectively filled by the internal support pressure, resulting in the pressure repair of the pipeline being relatively limited, and it is easy for sharp corners, protrusions, etc. to appear between the pressure gaps, resulting in poor deformation repair effect. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention provides a water supply pipe deformation repair device, which solves the problems raised in the background art.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A water supply pipe deformation repair device includes: a support platform;

[0008] The top block is arranged on the outside of the support platform, and there is at least one group of top blocks. The top blocks expand and move to form a circular ring structure, which fits the inner wall of the water supply pipe and applies an outward expansion force toward the inner diameter of the pipe to the deformed part of the water supply pipe;

[0009] The driving assembly is arranged at the center of the moving path of the top block, and is used to drive the top block to expand, contract and rotate, so that when the top block expands outward, an outward expansion force tending to the inner diameter of the water supply pipe is applied to the deformed part of the water supply pipe, and when the top block contracts, a rotational force is applied to the top block that coincides with its expansion gap to compensate for the pressure gap when the top block expands outward again.

[0010] Furthermore, it also includes:

[0011] The wedge block is located in the middle of the inner side of the top block and is fixed to the support platform through a positioning support rod, and moves relative to the top block;

[0012] The telescopic arms are arranged on both sides of the top block and fit with the wedge surface of the wedge block. When the top block expands and moves outward, the telescopic arms are pushed out of the top block by the thrust of the wedge surface of the wedge block, and the telescopic arms in the adjacent top blocks are pressed and contacted to compensate for the gap when the top block expands and moves, forming a closed-loop force on the top block.

[0013] Furthermore, it also includes:

[0014] A first wedge surface, located at the bottom of the wedge surface of the wedge block, provides the displacement required for the telescopic arm to be pushed out relative to the top block, so that the telescopic arm is pushed out from the top block when sliding relative to the first wedge surface;

[0015] The second wedge surface is located at the top of the wedge surface of the wedge block, providing the displacement required for the adjacent telescopic arms to press against each other, so that when the telescopic arms slide relative to the first wedge surface, they come into contact with the adjacent telescopic arms.

[0016] Furthermore, the top block and the telescopic arm both form a circular ring structure, and the center of the top block and the telescopic arm coincide with each other, so that when the top block expands and moves to form a circular ring structure to support the pipeline, the telescopic arms extend synchronously and press against each other to form a circular ring structure, compensating for the expansion gap of the top block's expansion movement, and forming a closed-loop force for the top block's outward expansion movement.

[0017] Furthermore, the driving assembly is used to drive the expansion and contraction movement of the top block, wherein the driving assembly includes:

[0018] A drive shaft, the drive shaft being located at the center of the moving path of the top block, one end of the drive shaft being rotatably connected to the first sleeve for driving the first sleeve to move along its axial direction;

[0019] The slide is arranged on the moving path of the top block and is fixed to the top block. A connecting rod connected to the first sleeve is provided at the bottom of the slide, so that the horizontal force applied by the drive shaft to the first sleeve is converted into a lifting force through the connecting rod, thereby pushing the top block on the slide to expand and contract.

[0020] Furthermore, the driving assembly is also used to drive the rotation of the top block during its contraction and movement, wherein the driving assembly further comprises:

[0021] a second frame disposed on a moving path of the drive shaft;

[0022] a rotating drum, the rotating drum being rotatably connected to the middle portion of the second frame and being fixedly connected to the support platform, the inner wall of the rotating drum being provided with at least one set of first chute grooves along its circumference, the inner wall of the rotating drum being provided with at least one set of second chute grooves staggered from the first chute grooves, and the first chute grooves and the second chute grooves being connected to each other to form a closed loop channel;

[0023] The second sleeve is arranged at the other end of the drive shaft, and the second sleeve is provided with at least one set of guide sliders along its radial direction, so that the horizontal force applied by the drive shaft to the second sleeve pushes the guide sliders to slide in the closed-loop channel between the first slide groove and the second slide groove.

[0024] Furthermore, the slotting direction of the first slide groove is parallel to the axial direction of the drive shaft, and the slotting direction of the second slide groove is inclined to the axial direction of the drive shaft, so that when the drive shaft drives the top block to expand and move, the guide slide buckle slides along the first slide groove to apply horizontal limit to the support platform, and when the drive shaft drives the top block to contract and move, the guide slide buckle slides along the second slide groove to apply rotational push to the support platform.

[0025] Furthermore, it also includes a travel assembly for driving the top block to move inside the water supply pipe, and the travel assembly drives the top block to move to the deformed part of the water supply pipe to perform repair work, wherein the travel assembly includes:

[0026] a housing, the housing being disposed on one side of the top block and being fixedly connected to the second frame;

[0027] A first frame, the first frame is arranged on the housing away from the second frame, and a track plate is provided on both sides of the first frame, and the track plate is provided with at least one set of track slides along the guide rail direction thereof;

[0028] The crawler propulsion structure is arranged in the displacement path direction of the track slide and is fixed to the track slide through a telescopic frame.

[0029] Furthermore, a driven gear is provided on one side of the track plate, a driving gear is meshed with one side of the driven gear, and a telescopic motor fixed to the casing is provided on the central axis of the driving gear.

[0030] Furthermore, a drive shell is provided in the direction of the moving path of the drive shaft, the drive shell passes through the track plate and is fixed to the casing, and an electric cylinder is provided in the drive shell to push the drive shaft to move horizontally.

[0031] The present invention has the following beneficial effects:

[0032] (1) The water supply pipe deformation repair device is driven by a driving component. When the driving top block expands and moves, a circular ring structure is formed to fit the inner wall of the water supply pipe, and an outward expansion force tending to the inner diameter of the pipe is applied to the deformed part of the water supply pipe. When the driving top block contracts and moves, the top block rotates and rotates to its expansion gap position to compensate for the pressure gap when the top block expands outward again, so that the top block rotates and expands cyclically along the deformed part of the water supply pipe, so as to apply an outward expansion force to various parts of the water supply pipe, eliminate the stress deformation caused by the local lack of force on the pipe, and improve the repair effect.

[0033] (2) The water supply pipe deformation repair device can cyclically apply pressure to the deformed part of the pipe in a step-by-step rotation and expansion manner through the cyclic rotation and expansion of the top block. On the one hand, it can apply uniform and comprehensive pressure repair force to the deformed part of the pipe, thereby improving the uniformity and comprehensiveness of the force during the repair of the deformed part of the water supply pipe. On the other hand, it can evenly transmit the pressure repair force to various parts of the pipe, maintain the force integrity during the deformation repair of the water supply pipe, and avoid the situation where the pipe is locally stressed and tensilely deformed.

[0034] (3) The water supply pipe deformation repair device, through the setting of the telescopic arm, makes the top block extend outward to form a circular ring structure when it expands outward, and compensates the force of the expansion gap of the top block, so that the outward expansion of the top block forms a closed-loop force. In an integrated force application method, a uniform pressure repair force is applied to the water supply pipe, reducing the uneven force on the water supply pipe caused by independent pressure application, and improving the water supply pipe deformation repair effect.

[0035] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0056] See also Figures 1-18 , an embodiment of the present invention provides a technical solution: a water supply pipe deformation repair device.

[0057] See also Figure 1-Figure 4 The water supply pipe deformation repair device includes a support platform 2, a top block 3 is provided on the outside of the support platform 2, and at least one group is provided. A driving component is provided at the center of the moving path of the top block 3. When the top block 3 is driven to expand and move, a circular ring structure is formed to fit the inner wall of the water supply pipe, and an outward expansion force tending to the inner diameter of the pipe is applied to the deformed part of the water supply pipe. At the same time, the driving component is used to drive the top block 3 to shrink and move, and a rotational force that coincides with its expansion gap is applied to the top block 3, so that the top block 3 rotates when it shrinks and moves, and rotates to coincide with its expansion gap to compensate for the pressure gap when the top block 3 expands outward again, so that the top block 3 rotates and expands outward along the deformed part of the water supply pipe in a cycle, so as to apply an outward expansion force to various parts of the water supply pipe, eliminate the stress deformation caused by the local lack of force on the pipe, and improve the repair effect.

[0058] In addition, a traveling component is provided on one side of the top block 3 to drive it to move inside the water supply pipe. The traveling component is used to drive the top block 3 to move to the deformed part of the water supply pipe for repair work. The deformation repair work of the water supply pipe can be completed without excavating or disassembling the water supply pipe.

[0059] See also Figure 1-Figure 7 In order to realize the movement of the top block 3 to the deformed part of the water supply pipe, the top block 3 is driven to move along the inner wall of the pipe by the driving of the traveling assembly, wherein the traveling assembly includes a casing 1 arranged on one side of the top block 3, a first frame 9 is provided on the casing 1, and track plates 10 are provided on both sides of the first frame 9. The track plate 10 is provided with at least one set of track slides 11 along its guide rail direction. The guide rail of the track plate 10 is set as a spiral track. The spiral thrust is converted into displacement thrust by sliding the track slide 11 along the spiral track of the track plate 10. A crawler propulsion structure 8 is provided in the displacement path direction of the track slide 11. The crawler propulsion structure 8 is telescopically extended. The frame 21 is fixedly connected to the track slide 11, and the crawler propulsion structure 8 is preferably set as three groups, which are supported and propelled by the inner wall of the water supply pipe in a star-triangle support manner, and the deformation repair device is placed in the center of the water supply pipe to be repaired. Then, based on the driving combination of the track plate 10 and the track slide 11, the crawler propulsion structure 8 is pushed to expand and move outward relative to the inner wall of the water supply pipe, fit against the inner wall of the water supply pipe, and support the deformation repair device on the inner wall of the water supply pipe. The crawler propulsion structure 8 is driven to drive the deformation repair device to travel and propel inside the water supply pipe, and the top block 3 is pushed to the deformed part of the water supply pipe for repair work.

[0060] Specifically, a driven gear 12 is provided on one side of the track plate 10, and a driving gear 13 is engaged with one side of the driven gear 12. The central axis of the driving gear 13 is provided with a telescopic motor 14 fixed to the casing 1. The telescopic motor 14 is used as a driving source to drive the driving gear 13 to rotate, and the engagement of the driving gear 13 and the driven gear 12 is used to drive the track plate 10 to rotate. The combination of the track plate 10 and the slide rail of the track slide 11 generates a driving force to drive the crawler propulsion structure 8 to expand and move outward.

[0061] Furthermore, the crawler propulsion structure 8 is composed of a crawler frame 81 as the main supporting structure and is fixedly connected to the telescopic frame 21. Drive wheels 83 are provided at both ends of the crawler frame 81, and a crawler belt 82 is provided between the two sets of drive wheels 83. A drive motor 84 is provided in the middle of the crawler frame 81. The drive motor 84 drives the combination of the first pulley 85, the transmission belt 86, and the second pulley 87 to drive one set of drive wheels 83 to rotate, and then under the tension of the other set of drive wheels 83, the crawler belt 82 is driven to rotate, pushing the deformation repair device to move forward on the inner wall of the water supply pipe.

[0062] See also Figure 1 、 Figure 4 、 Figures 8-14In order to realize the repair of the deformed part of the water supply pipe by driving the top block 3 of the driving component, the driving component drives the top block 3 to expand, contract and rotate, so that when the driving component drives the top block 3 to expand, a circular ring structure is formed to fit the inner wall of the water supply pipe, and an internal support and reset thrust is applied to the deformed part of the water supply pipe. When the driving component drives the top block 3 to reset and contract, the top block 3 is driven to rotate and coincide with the expanded gap part, so as to compensate for the pressure gap when the top block 3 expands again. Since water supply pipes often have stress, when the deformed parts of the water supply pipes are repaired, the stressed gap parts are prone to produce corners, protrusions, etc. under the action of stress, which makes the deformation repair effect of one time poor. The stress of the water supply pipes also makes it easy for deformation to be reset during a single internal support repair, resulting in that a single internal support repair often cannot meet the deformation part's original radius of the water supply pipe. By utilizing the step-by-step rotation expansion support of the top block 3, after a single internal support repair of the deformed part of the water supply pipe, the top block 3 can be rotated to coincide with the repaired gap part when it shrinks, so that when the top block 3 expands the internal support next time, the unstressed gap part is internally supported and the deformed part is repaired again at the same time, so as to maintain the expansion state of the step-by-step rotation, and apply uniform internal support repair to various parts of the water supply pipe, thereby realizing cyclic internal support repair of the deformed part of the water supply pipe.

[0063] Specifically, the driving assembly includes a driving shaft 7 arranged at the center of the moving path of the top block 3, and a driving shell 17 is provided in the moving path direction of the driving shaft 7. The driving shell 17 passes through the track disk 10 and is fixed to the casing 1. An electric cylinder 18 is provided in the driving shell 17 to push the driving shaft 7 to move horizontally. One end of the driving shaft 7 is rotatably connected to the first shaft sleeve 6. By arranging the first shaft sleeve 6 on the driving shaft 7 in a rotating form, the first shaft sleeve 6 has the ability to move horizontally with the driving shaft 7 while also having the ability to rotate relative to the driving shaft 7. When the top block 3 rotates, the first shaft sleeve 6 can be driven to rotate synchronously along the driving shaft 7, and the driving force of the first shaft sleeve 6 on the top block 3 is always maintained. At the same time, a slide 4 is provided on the moving path of the top block 3, the slide 4 is fixed to the top block 3, and a support is provided on the support table 2. A giveway slide groove 24 is provided for the displacement of the slide 4, so that the slide 4 can slide along the support platform 2 within a limited range. A connecting rod 5 connected to the first shaft sleeve 6 is provided at the bottom of the slide 4. When pushing the top block 3 to expand outward to repair the internal support of the deformed part of the water supply pipe, the electric cylinder 18 is used to drive the drive shaft 7 to move horizontally, and apply horizontal force to the first shaft sleeve 6, which is converted into a lifting force through the connecting rod 5, pushing the slide 4 to slide along the support platform 2, and expanding the top block 3 outward so that the top block 3 forms a circular ring structure and fits with the inner wall of the water supply pipe. While expanding outward, an internal support thrust is applied to the deformed part of the water supply pipe, pushing the deformed part toward the inner diameter of the pipe for deformation repair. After a single internal support repair, the electric cylinder 18 is used to drive the reverse movement of the drive shaft 7 to drive the top block 3 to reset and shrink inward.

[0064] Furthermore, the driving assembly also includes a second frame 15 arranged on the moving path of the driving shaft 7, the middle part of the second frame 15 is rotatably connected to the rotating drum 16, and the rotating drum 16 is fixed to the support table 2, and the inner wall of the rotating drum 16 is provided with at least one group of first sliding grooves 22 along its circumference, and the inner wall of the rotating drum 16 is staggered from the first sliding grooves 22 to provide at least one group of second sliding grooves 23, and the first sliding grooves 22 and the second sliding grooves 23 are connected to each other to form a closed loop channel. At the same time, a second shaft sleeve 19 is provided at the other end of the driving shaft 7, and the second shaft sleeve 19 is provided with at least one group of guide sliders 20 along its radial direction. The guide slider 20 can slide in the closed loop channel of the first sliding groove 22 and the second sliding groove 23. When the electric cylinder 18 drives the driving shaft 7 to move, it pushes the top block 3 to expand and move outward, and synchronously drives the second shaft sleeve 19 to move horizontally, so that the guide slider 20 on the second shaft sleeve 19 slides along the first sliding groove 22, and utilizes the guide slider 20 and the first sliding groove 2 When the electric cylinder 18 drives the driving shaft 7 to move in the opposite direction and pushes the top block 3 to return to its original position and retract, the guide slider 20 slides to the other end of the first slide groove 22. At this time, the guide slider 20 is guided by the bending of the overlapping ends of the two sets of slide grooves and slides into the second slide groove 23. The guide slider 20 slides along the second slide groove 23 to apply a rotational thrust to the drum 16, so that the drum 16 rotates along the second frame 15, and then the support platform 2 and the top block 3 on its outside rotate, so that the top block 3 keeps rotating while shrinking, rotates to its expansion gap position, and coincides with the expansion gap position. When the top block 3 expands next time to repair the water supply pipe internally, the gap of the last internal support repair can be compensated and repaired.

[0065] It should be noted that the slotting direction of the first slide groove 22 is parallel to the axial direction of the drive shaft 7, and the slotting direction of the second slide groove 23 is inclined to the axial direction of the drive shaft 7. By setting the first slide groove 22 parallel to the drive shaft 7, when the drive shaft 7 drives the guide slider 20 to slide along the first slide groove 22, the first slide groove 22 is horizontally limited, which plays a horizontal limiting role, and the combination of the rotating drum 16 and the support platform 2 is limited and fixed, so that the top block 3 maintains fixed-point expansion movement, and by setting the second slide groove 23 inclined to the drive shaft 7, when the drive shaft 7 drives the guide slider 20 to slide along the second slide groove 23, a thrust is applied to the second slide groove 23, and the linear thrust is converted into a rotational thrust, which is transmitted to the rotating drum 16, pushing the combination of the rotating drum 16 and the support platform 2 to rotate, so that the top block 3 maintains its own rotation while shrinking.

[0066] See also Figures 15-18In order to realize the integrated force when the top block 3 expands and moves to form a circular ring structure, a wedge block 301 is provided in the middle of the inner side of the top block 3, and a second clearance groove 28 for the sliding of the wedge block 301 is provided at the bottom of the top block 3. The wedge block 301 is fixed to the support platform 2 through a positioning support rod 29, so that the wedge block 301 can move relative to the top block 3. At the same time, telescopic arms 25 are provided on both sides of the top block 3, and first clearance grooves 27 for the extension of the telescopic arms 25 are provided on both sides of the top block 3. The telescopic arms 25 fit in with the wedge surface of the wedge block 301. When the top block 3 expands and moves outward, the top block 3 drives the telescopic arms 25 to move synchronously, so that The telescopic arm 25 moves relative to the wedge block 301, and then the telescopic arm 25 is gradually pushed out from the top block 3 by the thrust of the wedge surface of the wedge block 301. When the top block 3 expands outward to form a circular ring structure, the telescopic arm 25 in the adjacent top block 3 continues to extend and press into contact, forming a circular ring structure with the same center as the top block 3, so that the telescopic arm 25 and the top block 3 form a common circular ring structure, which compensates for the gap when the top block 3 expands and moves, and constitutes a closed-loop force on the top block 3. In an integrated force manner, a uniform internal support repair force is applied to the water supply pipe, thereby reducing the uneven force on the water supply pipe caused by independent pressure and improving the deformation repair effect of the water supply pipe.

[0067] As a further solution of this embodiment, the wedge block 301, the first wedge surface 302, and the second wedge surface 303 together constitute the wedge block structure 30, wherein the first wedge surface 302 is located at the bottom of the wedge surface of the wedge block 301, providing the displacement required for the telescopic arm 25 to be pushed out relative to the top block 3, so that when the telescopic arm 25 slides relative to the first wedge surface 302, it is pushed out from the top block 3, and the second wedge surface 303 is located at the top of the wedge surface of the wedge block 301, providing the displacement required for the adjacent telescopic arms 25 to press against each other, so that the telescopic arm 25 can be pushed out relative to the first wedge surface When the surface 302 slides, it comes into pressure contact with the adjacent telescopic arm 25. By setting the first wedge surface 302 and the second wedge surface 303 as inclined surfaces with different inclinations, when the top block 3 is expanding outward, the telescopic arm 25 slides along the first wedge surface 302 and is smoothly pushed out from the top block 3 without coming into contact with the adjacent telescopic arm 25. When the top block 3 expands outward to form a circular ring structure, the telescopic arm 25 slides along the second wedge surface 303 and suddenly accelerates the push-out movement, so that the adjacent telescopic arm 25 comes into pressure contact with each other, forming a circular ring structure with the top block 3 having the same center.

[0068] Furthermore, a compression spring 26 is provided on the moving path of the telescopic arm 25, so that when the top block 3 expands and drives the telescopic arm 25 to extend, the compression spring 26 is compressed and stored, and when the top block 3 resets and contracts, the telescopic arm 25 resets and contracts along the wedge surface of the wedge block structure 30 under the elastic reset force of the compression spring 26.

[0069] When in use, the deformation repair device is placed in the center of the water supply pipe to be repaired, and then based on the driving combination of the driving track plate 10 and the track slide 11, the crawler propulsion structure 8 is pushed to expand and move outward relative to the inner wall of the water supply pipe, so that the crawler propulsion structure 8 is supported at multiple points and fits the inner wall of the water supply pipe. The crawler propulsion structure 8 is driven to drive the deformation repair device to move inside the water supply pipe, and the top block 3 is pushed to the deformed part of the water supply pipe for repair work.

[0070] After the top block 3 moves to the deformed part of the water supply pipe, the outward expansion driving action of the driving component is utilized to drive the top block 3 to expand and move outward, so that in the process of forming a circular ring structure and fitting with the inner wall of the water supply pipe, the deformed part of the water supply pipe is repaired by internal support, and when the top block 3 expands and moves outward, the top block 3 drives the telescopic arms 25 to be gradually pushed out from the inside thereof. When the top block 3 expands outward to form a circular ring structure, the adjacent telescopic arms 25 in the top block 3 are pressed and contacted to form a circular ring structure cocentric with the top block 3, compensating for the gap when the top block 3 expands and moves, forming a closed-loop force on the top block 3, and transmitting the internal support force evenly to various parts of the water supply pipe in an integrated force state, thereby avoiding tensile deformation of the water supply pipe caused by local force.

[0071] After a single internal support repair is completed, the contraction driving action of the driving component is used to drive the top block 3 to reset and contract. While contracting, the top block 3 is driven to rotate and coincide with its expanded gap to compensate for the pressure gap when the top block 3 expands outward again. Then, in this way, the top block 3 is driven to apply uniform internal support repair to various parts of the water supply pipe in a state of step-by-step rotation and expansion, eliminating the stress deformation caused by the stress of the water supply pipe itself, and realizing uniform repair of the deformed parts of the water supply pipe.
