Description

Technical Field

[0001] This utility model relates to the technical field of pipeline repair auxiliary devices, and in particular to an adjustable-size pipeline repair anti-airbag slippage grid. Background Technology

[0002] Before the construction (inspection, dredging, and repair) of underground pipeline networks, water blocking and interception are required upstream and downstream of the pipeline section. This process involves airbag sealing engineering, which poses many safety hazards. Among them, accidents caused by airbag slippage are the most frequent. In the existing construction technology, there is a lack of standard anti-airbag slippage devices. The common practice is to place steel ladders vertically in the inspection well to prevent airbag slippage. This method can be effective for small-diameter pipelines, but when facing larger-diameter pipelines, the airbags are still prone to slippage. The existing technology lacks anti-airbag slippage devices that can be adapted to the repair of pipelines with various diameters. Therefore, it is necessary to provide an adjustable-size anti-airbag slippage grid for pipeline repair to solve the above technical problems. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides an adjustable-size pipe repair anti-airbag slippage grid.

[0004] This utility model provides an adjustable-size pipe repair anti-airbag slippage grid, including a telescopic rod component. Two sets of the telescopic rod components are symmetrically arranged, and several elastic ropes are arranged from top to bottom between the two sets of telescopic rod components. The telescopic rod component includes an outer tube, and two inner tubes facing opposite directions are symmetrically slidably arranged inside the outer tube. One end of the inner tube extends out of the outer tube and is fixedly connected to a fixed base. Both ends of the outer tube are provided with locking components for locking the inner tubes.

[0005] Preferably, the locking assembly includes an inner sleeve, which is fixedly connected to the end of the outer tube and sleeved on the outside of the inner tube. A locking nut is threaded onto the outer side of the inner sleeve. A plurality of circumferentially distributed locking pieces are fixedly connected at equal intervals to the front end of the inner sleeve. A first inclined portion is provided on the outer side of the locking piece, and a second inclined portion adapted to the first inclined portion is provided on the inner side of the locking nut.

[0006] Preferably, the inner sleeve and the outer tube are coaxially arranged.

[0007] Preferably, one elastic rope is fixedly connected between the two inner tubes at the same height of the two sets of telescopic rod components, and two elastic ropes are also fixedly connected between the two outer tubes of the two sets of telescopic rod components.

[0008] Preferably, each of the elastic cords is equipped with a spring buckle.

[0009] Preferably, a support component is provided between the two outer tubes. The support component includes a cylinder and a threaded rod. A fixing block is fixedly connected to one end of both the cylinder and the threaded rod. A connecting block corresponding to the fixing block is fixedly connected to the outer side wall of both outer tubes. Two insert rods are symmetrically fixedly connected to one side of the fixing block. An insertion hole adapted to the insert rod is opened through the connecting block. The insert rod is inserted into the corresponding insertion hole. An internal threaded sleeve is provided at the other end of the cylinder.

[0010] Preferably, one end of the internal threaded rotating sleeve near the cylinder is fixedly connected to an annular rotating rail with a T-shaped cross section, and the other end of the cylinder is provided with an annular groove adapted to the annular rotating rail. The annular rotating rail is rotatably disposed in the annular groove, the internal threaded rotating sleeve is threadedly sleeved on the outside of the threaded rod, and the other end of the threaded rod extends into the cylinder and is fixedly connected to a square block, which is slidably connected in the cylinder.

[0011] Compared with related technologies, the adjustable-size anti-airbag slippage grid for pipe repair provided by this utility model has the following beneficial effects:

[0012] 1. By loosening the locking nut, the pressure of the second inclined part on the first inclined part can be released, so that the locking plate is no longer pressed against the inner tube side wall. This allows for flexible adjustment of the length of the inner tube extending beyond the outer tube according to the pipe diameter requirements, so that the fixed base contacts the pipe wall. After adjustment, tighten the locking nut. With the pressure of the second inclined part on the first inclined part, the locking plate will undergo elastic deformation and move towards the outer wall of the inner tube. The friction between the locking plate and the outer wall of the inner tube will lock the inner tube in place, ensuring that the telescopic rod component can stably adapt to pipes of different diameters and providing a reliable support foundation for preventing airbag slippage.

[0013] 2. The tension ropes are connected between the two inner tubes and the two outer tubes at the same height of the two sets of telescopic rod components. The spring buckles are installed on the tension ropes, and the length of the tension ropes can be easily adjusted through the spring buckles. The tension ropes can be adjusted to a suitable tension state according to the adjustment of the telescopic rod components and the actual needs of the pipeline, further enhancing the overall compatibility and stability of the grid with the pipeline, and better limiting the airbag to prevent the airbag from slipping off.

[0014] 3. With the threaded connection between the threaded rod and the internal threaded swivel, rotating the internal threaded swivel causes the threaded rod to move along the length of the cylinder, thereby adjusting the overall length of the cylinder and the threaded rod. At the same time, inserting the insert rod on the fixing block into the insertion hole of the connecting block can achieve a stable connection between the support component and the two sets of telescopic rod components. This allows for flexible adjustment of the distance between the two sets of telescopic rod components to adapt to pipes of different diameters, and also provides stable support for the two sets of telescopic rod components, improving the overall structural stability of the grid and the anti-airbag slippage effect.

[0015] 4. This utility model fills the gap in pipeline repair projects where there is no dedicated device for preventing airbag slippage. The grid is adjustable as a whole, which can meet the usage requirements of different pipe diameters and improve the scope of application. It solves the problem of easy slippage after the airbag is sealed in larger diameter pipes. The easy adjustment method allows this anti-airbag slippage grid to meet the needs of various pipe diameters. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1

[0023] Please refer to the following: Figures 1 to 4 An adjustable-size pipe repair anti-airbag slippage grid includes a telescopic rod component 1, with two sets of telescopic rod components 1 symmetrically arranged, and several elastic ropes 2 arranged from top to bottom between the two sets of telescopic rod components 1; the telescopic rod component 1 includes an outer tube 101, and two inner tubes 102 symmetrically and slidingly arranged inside the outer tube 101, facing opposite directions; one end of the inner tube 102 extends out of the outer tube 101 and is fixedly connected to a fixed base 104; both ends of the outer tube 101 are provided with locking components 103 for locking the inner tubes 102; the inner tubes 102 and the outer tube 101 are preferably stainless steel tubes with a length of 500mm, and the elastic ropes 2 are preferably high-elasticity elastic ropes with a length of 1200mm.

[0024] In the above, the outer tube 101 provides a stable sliding support space for the inner tube 102. The inner tube 102 slides flexibly along the axial direction of the outer tube 101, thereby changing the overall length of the telescopic rod component 1 to meet the support length requirements of pipes with different diameters. The fixed base 104 keeps in contact with the pipe wall to improve the fixed stability of the telescopic rod component 1 in the pipe. The locking component 103 ensures that the adjusted inner tube 102 will not slide arbitrarily, ensuring the reliability of the support of the telescopic rod component 1. The inner tube 102 and outer tube 101 are made of stainless steel, which can enhance the corrosion resistance and structural strength of the components and adapt to the complex environment inside the pipe. The high-elasticity elastic rope 2 has good elasticity.

[0025] Furthermore, the locking assembly 103 includes an inner sleeve 1031, which is fixedly connected to the end of the outer tube 101 and sleeved on the outside of the inner tube 102. A locking nut 1032 is threaded onto the outer side of the inner sleeve 1031. Several locking plates 1033 are fixedly connected at equal intervals at the front end of the inner sleeve 1031 in a circularly distributed manner. The locking plates 1033 can be made of spring steel. A first inclined portion 1034 is provided on the outer side of the locking plate 1033. A second inclined portion 1035 adapted to the first inclined portion 1034 is provided on the inner side of the locking nut 1032. The inner sleeve 1031 and the outer tube 101 are coaxially arranged.

[0026] In the above, the inner sleeve 1031 and the outer tube 101 are coaxially arranged, which can ensure that the inner tube 102 always slides along the axial direction, avoiding offset and jamming, and ensuring the smooth adjustment of the telescopic rod component 1. The threaded engagement between the locking nut 1032 and the inner sleeve 1031 can achieve compression control of the locking plate 1033 by rotation. When the locking nut 1032 is tightened, the second inclined part 1035 presses the first inclined part 1034, causing the circumferentially distributed locking plates 1033 to contract inward synchronously and fit tightly against the outer wall of the inner tube 102. The friction force is used to firmly fix the inner tube 102 and prevent it from sliding under force. After the locking nut 1032 is loosened, the locking plate 1033 returns to its deformation, releasing the restraint on the inner tube 102, which makes it easy to readjust the length of the inner tube 102.

[0027] Furthermore, one elastic rope 2 is fixedly connected between each of the two inner tubes 102 at the same height of the two sets of telescopic rod components 1. The two ends of the elastic rope 2 are fixedly connected to the outer walls of the two inner tubes 102 respectively. Two elastic ropes 2 are also fixedly connected between each of the two outer tubes 101 of the two sets of telescopic rod components 1. The two elastic ropes 2 are arranged parallel to each other vertically. The two ends of the two elastic ropes 2 are fixedly connected to the outer walls of the two outer tubes 101 respectively. Hanging rings can be welded at corresponding positions on the outer walls of the outer tubes 101 and inner tubes 102. The ends of the elastic ropes 2 are fixed to the hanging rings of the corresponding outer tubes 101 and inner tubes 102 by a binding method, and the binding points are locked with buckles to achieve a fixed connection with the outer tubes 101 and inner tubes 102.

[0028] In the above, the setting of multiple sets of elastic ropes 2 can restrain the slippage of the airbag and improve the effect of preventing the airbag from slipping out.

[0029] Furthermore, each elastic cord 2 is equipped with a spring buckle 3, which adjusts the length of the elastic cord 2. The spring buckle 3 is a press-type spring buckle commonly available on the market.

[0030] In the above, the length of the tension rope 2 is adjusted by the spring buckle 3. When the length of the telescopic rod component 1 increases or the distance between the two sets of telescopic rod components 1 changes, the tension rope 2 is stretched or shortened by the spring buckle 3 to keep it in a suitable tension state and ensure that the tension rope 2 can stably play the role of limiting the airbag.

[0031] Example 2

[0032] For further details, please refer to [link / reference]. Figures 1 to 4 Based on Embodiment 1, a support component 4 is provided between the two outer tubes 101. The support component 4 includes a cylinder 401 and a threaded rod 403. A fixing block 404 is fixedly connected to one end of both the cylinder 401 and the threaded rod 403. A connecting block 406 corresponding to the fixing block 404 is fixedly connected to the outer side wall of both outer tubes 101. Two insert rods 405 are symmetrically fixedly connected to one side of the fixing block 404. An insertion hole 407 adapted to the insert rod 405 is opened through the connecting block 406. The insert rod 405 is inserted into the corresponding insertion hole 407. An internal threaded rotating sleeve 402 is provided at the other end of the cylinder 401.

[0033] In the above, the cooperation between the cylinder 401 and the threaded rod 403 provides rigid support for the two sets of telescopic rod components 1, preventing the two sets of telescopic rod components 1 from getting close to or far away from each other when under force, thus ensuring the stability of the overall structure of the grid. The insertion rod 405 on the fixing block 404 cooperates with the insertion hole 407 of the connecting block 406, realizing the quick disassembly and assembly of the support component 4 and the telescopic rod component 1, which facilitates the transportation and assembly of the grid.

[0034] Furthermore, the internal threaded swivel 402 is fixedly connected to an annular rotating rail 4021 with a T-shaped cross section at one end near the cylinder 401. The other end of the cylinder 401 is provided with an annular groove that matches the annular rotating rail 4021. The annular rotating rail 4021 is rotatably disposed in the annular groove. The internal threaded swivel 402 is threadedly sleeved on the outside of the threaded rod 403. The other end of the threaded rod 403 extends into the cylinder 401 and is fixedly connected to a square block 408. The square block 408 is slidably connected inside the cylinder 401. The inner cavity of the cylinder 401 is a square inner cavity that matches the square block 408.

[0035] In the above, the cooperation between the annular rotating track 4021 and the annular sliding groove not only realizes the free rotation of the internal threaded rotating sleeve 402, but also prevents the internal threaded rotating sleeve 402 from undergoing axial displacement during rotation, ensuring that the internal threaded rotating sleeve 402 always maintains a stable threaded engagement with the threaded rod 403. When the internal threaded rotating sleeve 402 is rotated, the threaded rod 403 can move precisely along the length direction of the cylinder 401, thereby accurately adjusting the overall length of the cylinder 401 and the threaded rod 403, and thus achieving precise control of the distance between the two sets of telescopic rod components 1 to adapt to the needs of pipes with different diameters. At the same time, it ensures the stability of the support force of the support component 4 on the two sets of telescopic rod components 1. The square block 408 can slide along its length direction inside the cylinder 401, and the square block 408 restricts the circumferential rotation of the threaded rod 403.

[0036] The working principle of the adjustable-size pipe repair anti-airbag slippage grid provided by this utility model is as follows:

[0037] In use, during pipeline repair work, firstly, airbags are placed to seal the pipeline. Airbags of different sizes are used to seal and cut off the flow according to different pipe diameters. Then, the anti-airbag slippage grid of this invention is placed, adjusted according to the pipe diameter. By loosening the locking nut 1032, the second inclined part 1035 is prevented from compressing the first inclined part 1034. At this time, the locking piece 1033 does not press against the side wall of the inner tube 102. Then, the length of the inner tube 102 extending beyond the outer tube 101 is adjusted according to the required pipe diameter, so that the fixed base 104 and the pipeline... The tube wall contacts the inner tube 102, and then the locking nut 1032 is tightened by the threaded connection between the locking nut 1032 and the inner sleeve 1031. The locking nut 1032 drives the second inclined part 1035 to press against the first inclined part 1034, causing the locking plate 1033 to undergo elastic deformation. The circumferentially distributed locking plates 1033 move closer to and press against the outer wall of the inner tube 102. The friction between the locking plates 1033 and the outer wall of the inner tube 102 locks and fixes the inner tube 102, keeping it in the current position before moving it. The distance between the two sets of telescopic rod components 1 can be adjusted as needed. With the threaded connection between the threaded rod 403 and the internal threaded sleeve 402, rotating the internal threaded sleeve 402 causes the square block 408 to slide within the cylinder 401, moving the threaded rod 403 along the length of the cylinder 401. This allows the insertion rod 405 on the fixing block 404 connecting both ends of the cylinder 401 and the threaded rod 403 to be inserted into the corresponding insertion hole 407. The support member 4 supports the two sets of telescopic rod components 1, enabling adjustment of the distance between them and allowing for further adjustment of the distance between the two sets of telescopic rod components 1. The spring buckle 3 provides stable support and allows for adjustment of the length of the elastic rope 2. The operator holds the spring buckle 3 housing with one hand, presses the movable button on the spring buckle with their thumb, causing the internal locking component to overcome the spring force and disengage from the rope, releasing the locking of the elastic rope 2. While maintaining the pressed position, the operator simultaneously pulls both ends of the elastic rope 2 to both sides until the entire elastic rope 2 is taut. Then, the operator releases the movable button, and the internal locking structure of the spring buckle automatically locks the elastic rope 2, tightening it and adjusting its length to the required position.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
