Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipeline deformation repair technology, and in particular to a pipeline deformation repair device. Background Technology
[0002] Currently, many underground pipelines intersect and are complex, and some pipelines have experienced frequent leaks and ruptures after years of use. The repair work of pipelines adopts the excavation repair technology and the internal pipeline repair. The excavation repair technology uses excavation equipment to excavate the trenches where the pipeline is laid, and then fills the trench after the pipeline is installed, repaired or replaced. Excavation may cause secondary damage to the pipeline. Therefore, repair devices can be used to assist in the repair of pipelines.
[0003] A search revealed patent document CN 218208413 U, which discloses a support bracket with a repair mechanism for repairing pipes. The support bracket includes a support mechanism for securing the bracket, comprising two screws movably connected to the bracket and a drive assembly for moving the screws towards or away from the inner wall of the pipe. The ends of the two screws that are far apart from each other are provided with clamping elements for securing the bracket to the inside of the pipe. This application offers the advantages of preventing slippage during use of the repair mechanism, and providing a simple and convenient support and fixing process, as well as flexible and convenient movement.
[0004] In the aforementioned prior art, the entire device is supported by a T-shaped bracket and moves inside the pipe with casters. The overall center of gravity of the device is biased towards the center of the pipe, which makes the device prone to tipping over during movement and affects its use. Therefore, a new pipe deformation repair device is proposed to optimize the aforementioned prior art. Utility Model Content

Simultaneously, a second hydraulic telescopic cylinder drives a second wedge-shaped seat to press against the first wedge-shaped seat, thereby causing the clamping block to press against the inner wall of the pipe, forming a fixed position. The combination of electric and hydraulic drives saves manpower. A second motor drives a second drive gear to rotate, which in turn drives a second rotating gear, causing the second platform to rotate along the axis of the second rotating gear. This controls the position of the two first hydraulic telescopic cylinders against the pipe. The first hydraulic telescopic cylinders drive a shaping head to repair deformed areas of the pipe.

Figure 5 As shown, the first rotating gear 7 has a through hole at its center, through which the extension end of the second hydraulic telescopic cylinder 18 passes. The first rotating gear 7 and the inverted V-shaped support leg 2 are rotatably connected by a bearing. The inner ring of the bearing is interference-fitted with the outer ring of the first rotating gear 7 shaft, and the outer ring of the bearing is interference-fitted with the mounting groove on the inverted V-shaped support leg 2. The first motor 9 is fixedly connected to the U-shaped beam 4.
[0028] Preferably, in this embodiment, the external support mechanism includes: two end plates 12 symmetrically arranged at the front end of the first base 6; connecting rods 13 slidably connected to the two end plates 12; guide sleeves 14 slidably connected to the connecting rods 13; a limiting plate 19 fixedly connected to the connecting rods 13; a return spring 20 sleeved on the connecting rods 13; a first wedge-shaped seat 16 disposed at one end of the connecting rod 13 extending out of the guide sleeve 14; a second wedge-shaped seat 17 disposed between the two first wedge-shaped seats 16; and a second hydraulic telescopic cylinder 18 whose telescopic end is rotatably connected to the second wedge-shaped seat 17. Figure 5 and Figure 6 As shown, in this embodiment, the telescopic end of the second hydraulic telescopic cylinder 18 is fixedly connected to an I-beam connecting block 25. The inner side of the I-beam connecting block 25 is symmetrically provided with two steps. A plane bearing 26 is fitted on the opposite surface of the two steps. The end face of the plane bearing 26 is in contact with the surface of the second wedge seat 17. A rotary bearing 27 is fitted in the middle of the I-beam connecting block 25. The I-beam connecting block 25 is rotatably installed with the second wedge seat 17 through the rotary bearing 27. The outer ring of the rotary bearing 27 is interference-fitted with the second wedge seat 17. Specifically, in this embodiment, the I-beam connecting block 25 includes a first connecting part 28 and a second connecting part 29. The first connecting part 28 is convex, and the second connecting part 29 is circular. The second connecting part 29 is connected to the first connecting part 28 by bolts.
[0029] A limiting plate 19 is placed between a guide sleeve 14 and an end plate 12, and a return spring 20 is placed between the limiting plate 19 and the end plate 12. A second wedge-shaped seat 17 is adapted to a first wedge-shaped seat 16, and the inclined surface of the second wedge-shaped seat 17 slides in contact with the inclined surface of the first wedge-shaped seat 16. The guide sleeve 14 is fixed to a first base 6. A second hydraulic telescopic cylinder 18 is fixedly connected to an inverted V-shaped support leg 2, and the telescopic end of the second hydraulic telescopic cylinder 18 passes sequentially through a first rotating gear 7, a first base 6, and is rotatably connected to the second wedge-shaped seat 17. Clearance holes are provided on the first rotating gear 7 and the first base 6. In this embodiment, the first motor 9 is connected to an external power source via an electrical wire; the second hydraulic telescopic cylinder 18 is connected to a hydraulic system via a pipe 1.
[0030] Preferably, in this embodiment, the end of the connecting rod 13 away from the second wedge seat 17 is provided with a clamping block 15, and the outer wall of the clamping block 15 is fixedly connected with an anti-slip pad.
[0031] In this embodiment, the first motor 9 drives the first drive gear 8 to rotate, which in turn drives the first rotating gear 7 to rotate, allowing the first base 6 to rotate along the axis of the first rotating gear 7, thereby controlling the position of the clamping block 15 against the pipe 1. Simultaneously, the second hydraulic telescopic cylinder 18 drives the second wedge seat 17 to press against the first wedge seat 16, thus causing the clamping block 15 to press against the inner wall of the pipe 1, forming a fixed position. This combination of electric and hydraulic drive achieves a labor-saving effect. Example 3
[0032] Based on Examples 1 and 2, such as Figure 4 and Figure 5 As shown, preferably, in this embodiment, the shaping mechanism includes: a second rotating gear 22, a second base 21 fixedly connected to the second rotating gear 22, a second drive gear 23 meshing with the second rotating gear 22, a second motor 24 whose output shaft is fixedly connected to the first drive gear 8, and two first hydraulic telescopic cylinders 10 symmetrically arranged on the second base 21; the second rotating gear 22 is rotatably connected to the inverted V-shaped support leg 2, as shown in the figure. Figure 5 As shown, the second rotating gear 22 is rotatably connected to the inverted V-shaped support leg 2 via a bearing. The inner ring of the bearing is interference-fitted with the outer ring of the second rotating gear 22 shaft, and the outer ring of the bearing is interference-fitted with the mounting groove on the inverted V-shaped support leg 2. The second motor 24 is fixedly connected to the U-shaped beam 4. In this embodiment, the second motor 24 is connected to an external power source via an electrical wire. The first hydraulic telescopic cylinder 10 is connected to the hydraulic system via a pipe 1.
[0033] In this embodiment, the second motor 24 drives the second drive gear 23 to rotate, which in turn drives the second rotating gear 22 to rotate, causing the second base 21 to rotate along the axis of the second rotating gear 22, thereby controlling the position where the two first hydraulic telescopic cylinders 10 abut against the pipe 1. The first hydraulic telescopic cylinders 10 can be used to repair deformed areas of the pipe 1. Example 4
[0034] Based on Examples 1 to 3, such as Figures 1 to 5 As shown, preferably, in this embodiment, the extension end of the first hydraulic telescopic cylinder 10 is provided with a shaping head 11.
[0035] In this embodiment, when using this device to repair pipe 1, the device is placed inside pipe 1. The inverted V-shaped support leg 2 is supported inside pipe 1 by the bullseye wheel 3. Under the action of the counterweight base 5, the device remains vertical inside pipe 1. Then, the device is moved inside pipe 1 to the position requiring reshaping. After that, the first motor 9 of the fixing mechanism can be activated. The first motor 9 drives the first drive gear 8 to rotate, which in turn drives the first rotating gear 7 to rotate. This allows the first base 6 to rotate along the axis of the first rotating gear 7, thus avoiding the deformed position. At this time, the second wedge block is further pulled by the second hydraulic telescopic rod. The second wedge seat 17 presses against the first wedge seat 16, thereby... Pushing the connecting rod 13 compresses the return spring 20, causing the clamping block 15 to be pushed out and pressed against the inner wall of the pipe 1 to form a fixed effect. Then, the second motor 24 of the shaping mechanism is further activated. The second motor 24 drives the second drive gear 23 to rotate. Through the second drive gear 23, the second rotating gear 22 is rotated, which can make the second base 21 rotate along the axis of the second rotating gear 22 to control the position of the two first hydraulic telescopic cylinders 10 against the pipe 1, so that the shaping head 11 corresponds to the deformed position. The first hydraulic telescopic cylinder 10 is further activated to drive the shaping head 11 to press against the deformed position of the pipe 1 for repair and support. After the support is in place, the pipe 1 is shaped by the shaping head 11.
[0036] After the first shaping is completed, the first hydraulic telescopic cylinder 10 is retracted, and at the same time, the second hydraulic telescopic cylinder 18 drives the second wedge seat 17 to push out. At this time, the return spring 20 drives the connecting rod 13 to return to its original position, so that the first wedge seat 16 and the second wedge seat 17 remain in contact. At this time, the clamping block 15 does not abut against the inner wall of the pipe 1. Then, the moving device in the pipe 1 moves to the next position that needs shaping for shaping.
[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Substitutions may include replacements for some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the scope of protection of this utility model.
