Description

Technical Field

[0001] This utility model relates to the field of pipeline repair technology, and in particular to an auxiliary device for trenchless pipeline lining repair construction. Background Technology

[0002] In the construction of stainless steel lining for trenchless pipeline repair, repair equipment needs to be transported in from outside and then installed inside the pipeline at the damaged area. The repair equipment will then repair the damaged area, thereby achieving the purpose of pipeline repair.

[0003] Repair equipment must be transported to the repair site by a transport device before it can be used. Existing walking equipment is limited to pipes of a fixed diameter due to its fixed size, which reduces the practicality of the device. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides an auxiliary device for trenchless pipeline lining repair construction.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an auxiliary device for trenchless pipeline lining repair construction, comprising a support rod, a sliding rod fixedly installed on the side wall of the support rod, a support sleeve sleeved on the outer wall of the sliding rod, the support sleeve being slidably connected to the sliding rod, the diameter of the support rod being equal to the diameter of the support sleeve, a plurality of arc-shaped plates distributed in a circumferential array on the outer wall of the support sleeve, rollers being installed on the outer wall of each of the plurality of arc-shaped plates, and an adjustment component for adjusting the diameter of the plurality of arc-shaped plates being jointly provided on the support sleeve and the support rod.

[0006] By adopting the above technical solution, when workers need to repair pipelines, they need to install the repair equipment onto the curved plate. Then, the workers place the device inside the pipeline. At this point, the workers need to adjust the diameter of the curved plate using the adjusting components, thereby causing the rollers fixed to the curved plate to press against the inner wall of the pipeline. The workers can then move the main body of the device using the rollers. During this process, because the diameter of the curved plate is adjustable, it can move within pipelines of different diameters, thus improving the practicality of the device.

[0007] Furthermore, the adjustment assembly includes two first rotating seats respectively fixedly mounted on the outer walls of the support sleeve and the support rod, two second rotating seats mounted on the inner wall of the arc plate, and two rotating rods respectively rotatably mounted in the two first rotating seats. The other ends of the two rotating rods are rotatably connected to the two second rotating seats, and the two rotating rods are rotatably connected.

[0008] By adopting the above technical solution, when the operator needs to adjust the diameter of the arc plate, the operator needs to slide the support sleeve, which causes one of the first rotating seats to move with the support sleeve under the action of the support sleeve. This causes the rotating rod to rotate relative to the first and second rotating seats, and then causes one of the second rotating seats to slide along the arc plate, thereby changing the diameter of the arc plate. This causes the rollers fixed on the arc plate to press against the inner wall of the pipe. At this time, the operator can move the main body of the device through the rollers. During this process, since the diameter of the arc plate is adjustable, it can move in pipes of different diameters, thereby improving the practicality of the device.

[0009] Furthermore, a rotating groove is provided on the side wall of the slide rod, and a threaded rod is rotatably disposed in the rotating groove, and the support sleeve is threadedly connected to the threaded rod.

[0010] By adopting the above technical solution, when the worker needs to slide the support sleeve, the worker needs to rotate the threaded rod, which in turn causes the support sleeve to slide under the action of the threaded rod. This reduces the difficulty for the worker in sliding the support sleeve, thereby reducing the workload. Furthermore, the threaded rod also reduces the probability of the support sleeve slipping under external force, thus improving the stability of the device.

[0011] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the threaded rod.

[0012] By adopting the above technical solution, when the threaded rod rotates, the annular block rotates under the action of the threaded rod. During this process, the annular block limits the threaded rod, thereby reducing the probability of the threaded rod moving and improving the stability of the device.

[0013] Furthermore, two mutually symmetrical limiting rods are fixedly installed on the outer wall of the slide rod, and two mutually symmetrical limiting grooves are opened through the outer wall of the support sleeve, with the limiting rods and limiting grooves matching each other.

[0014] By adopting the above technical solution, the limiting rod reduces the probability of the support sleeve and the threaded rod rotating synchronously, thereby improving the stability of the device.

[0015] Furthermore, one of the second rotating seats is fixed to the arc-shaped plate, and the other second rotating seat is slidably connected to the inner wall of the arc-shaped plate. A guide rod is fixedly provided on the side wall of one of the second rotating seats, and the guide rod passes through the other second rotating seat and is slidably connected to it.

[0016] By adopting the above technical solution, the guide rod limits the sliding second rotating seat, thereby reducing the probability of the second rotating seat separating from the arc plate and thus improving the stability of the device.

[0017] Furthermore, a baffle plate is fixedly installed on the side wall of the guide rod.

[0018] By adopting the above technical solution, the baffle plate reduces the probability of the second rotating seat and the guide rod separating from each other, thereby improving the stability of the device.

[0019] In summary, this utility model has the following beneficial effects: 1. In this application, when workers need to repair a pipeline, they must install the repair equipment onto the curved plate. Then, the workers place the device inside the pipeline. At this point, the workers need to adjust the diameter of the curved plate using an adjusting assembly, thereby causing the rollers fixed to the curved plate to press against the inner wall of the pipeline. The workers can then move the main body of the device using the rollers. During this process, because the diameter of the curved plate is adjustable, it can move within pipelines of different diameters, thus improving the practicality of the device. 2. In this application, when the operator needs to adjust the diameter of the arc plate, the operator needs to slide the support sleeve, so that one of the first rotating seats moves with the support sleeve under the action of the support sleeve, thereby causing the rotating rod to rotate relative to the first rotating seat and the second rotating seat, and then causing one of the second rotating seats to slide along the arc plate, thereby changing the diameter of the arc plate, and then causing the roller fixed on the arc plate to press against the inner wall of the pipe. At this time, the operator can move the main body of the device through the roller. During this process, since the diameter of the arc plate is adjustable, it can move in pipes of different diameters, thereby improving the practicality of the device. 3. In this application, when the worker needs to slide the support sleeve, the worker needs to rotate the threaded rod, which causes the support sleeve to slide under the action of the threaded rod. In this process, the difficulty for the worker to slide the support sleeve is reduced, thereby reducing the difficulty of the worker's work. In addition, the threaded rod also reduces the probability of the support sleeve sliding when subjected to external force, thereby improving the stability of the device. Attached Figure Description

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0023] like Figure 1-4 As shown in the illustration, this application discloses an auxiliary device for trenchless pipeline lining repair construction, including a support rod 1, a sliding rod 11, a support sleeve 12, an arc-shaped plate 13, rollers 14, an adjusting assembly 2, and a threaded rod 31. The support rod 1 is a round rod structure with a horizontal axis. The sliding rod 11 is also a round rod structure with its axis coinciding with the axis of the support rod 1, and is fixedly mounted on the side wall of the support rod 1. The support sleeve 12 is fitted onto the outer wall of the sliding rod 11, with its axis coinciding with the axis of the sliding rod 11, and is slidably connected to the sliding rod 11. The diameter of the support rod 1 is equal to the diameter of the support sleeve 12. Multiple arc-shaped plates 13 are arranged in a circumferential array on the outer wall of the support sleeve 12, and rollers 14 are mounted on the outer walls of the multiple arc-shaped plates 13.

[0024] When pipeline repairs are required, the repair equipment is installed on the curved plate 13. The equipment is then placed inside the pipeline. At this point, the diameter of the curved plate 13 is adjusted using the adjusting component 2, causing the rollers 14 fixed to the curved plate 13 to press against the inner wall of the pipeline. The equipment can then be moved using the rollers 14. Because the diameter of the curved plate 13 is adjustable, the equipment can move within pipelines of different diameters, thus improving its practicality.

[0025] Adjustment assembly 2 is mounted on support sleeve 12 and support rod 1, and is used to adjust the diameter of multiple arc-shaped plates 13. Adjustment assembly 2 includes a first rotating seat 21, a second rotating seat 22, and a rotating rod 23. Two first rotating seats 21 are provided and fixedly mounted on the outer walls of support sleeve 12 and support rod 1, respectively. Two second rotating seats 22 are provided and mounted on the inner walls of arc-shaped plates 13. Two rotating rods 23 are provided and rotatably mounted in the two first rotating seats 21, respectively. The other ends of the two rotating rods 23 are rotatably connected to the two second rotating seats 22, respectively.

[0026] When the operator needs to adjust the diameter of the arc plate 13, the operator slides the support sleeve 12, causing one of the first rotating seats 21 to move with the support sleeve 12 under its action. This causes the rotating rod 23 to rotate relative to the first rotating seat 21 and the second rotating seat 22, causing one of the second rotating seats 22 to slide along the arc plate 13. This changes the diameter of the arc plate 13, causing the roller 14 fixed on the arc plate 13 to press against the inner wall of the pipe. At this time, the operator can move the main body of the device through the roller 14. During this process, since the diameter of the arc plate 13 is adjustable, it can move in pipes of different diameters, thereby improving the practicality of the device.

[0027] A rotating groove 3 is provided on the side wall of the slide rod 11. The threaded rod 31 is rotatably disposed in the rotating groove 3, and its axis coincides with the axis of the support sleeve 12. The support sleeve 12 is threadedly connected to the threaded rod 31.

[0028] When the operator needs to slide the support sleeve 12, they need to rotate the threaded rod 31, which causes the support sleeve 12 to slide under the action of the threaded rod 31. In this process, the difficulty of sliding the support sleeve 12 is reduced, thereby reducing the difficulty of the operator's work. In addition, the threaded rod 31 also reduces the probability of the support sleeve 12 sliding when subjected to external forces, thereby improving the stability of the device.

[0029] To improve the stability of the device, an annular groove 4 is formed on the inner wall of the rotating groove 3, and an annular block 41 is rotatably disposed in the annular groove 4. The annular block 41 is fixed to the threaded rod 31. When the threaded rod 31 rotates, the annular block 41 rotates under the action of the threaded rod 31. During this process, the annular block 41 limits the threaded rod 31, thereby reducing the probability of the threaded rod 31 moving and thus improving the stability of the device.

[0030] To improve the stability of the device, two symmetrical limiting rods 5 are fixedly installed on the outer wall of the slide rod 11, and two symmetrical limiting grooves 51 are formed through the outer wall of the support sleeve 12. The limiting rods 5 and the limiting grooves 51 are matched with each other. The limiting rods 5 reduce the probability of the support sleeve 12 and the threaded rod 31 rotating synchronously, thereby improving the stability of the device.

[0031] To improve the stability of the device, one of the second rotating seats 22 is fixed to the arc-shaped plate 13, and the other second rotating seat 22 is slidably connected to the inner wall of the arc-shaped plate 13. A guide rod 6 is fixedly installed on the side wall of one of the second rotating seats 22, and the guide rod 6 passes through the other second rotating seat 22 and is slidably connected to it. The guide rod 6 limits the sliding second rotating seat 22, thereby reducing the probability of the second rotating seat 22 separating from the arc-shaped plate 13, thus improving the stability of the device.

[0032] To improve the stability of the device, a baffle plate 7 is fixedly installed on the side wall of the guide rod 6. The baffle plate 7 reduces the probability of the second rotating seat 22 separating from the guide rod 6, thereby improving the stability of the device.

[0033] The operating principle of the auxiliary device for trenchless pipeline lining repair in this embodiment is as follows: When workers need to repair the pipeline, they install the repair equipment onto the arc-shaped plate 13. Then, the workers place the device inside the pipeline. At this time, the workers adjust the diameter of the arc-shaped plate 13 using the adjusting component 2, thereby causing the rollers 14 fixed on the arc-shaped plate 13 to press against the inner wall of the pipeline. The workers can then move the main body of the device using the rollers 14. During this process, since the diameter of the arc-shaped plate 13 is adjustable, it can move within pipelines of different diameters, thus improving the practicality of the device.

[0034] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
