Description

Technical Field

[0001] This utility model relates to the field of rope traction technology for pipeline lining repair, and specifically to a rope traction device for pipeline lining repair. Background Technology

[0002] In the field of pipeline lining repair technology, rope traction devices currently used for pipeline lining repair typically include basic components such as mounting frames, connecting sleeves, pull ropes, air inlet pipes, rollers, and connectors. The usage process is roughly as follows: First, the lining to be repaired is placed on the connecting sleeve at the bottom of the mounting frame. The lining is initially fixed by the sealing structure of the outer wall of the connecting sleeve. Then, the air inlet pipe is connected to an external inflation device. Gas enters the connecting sleeve through the air inlet pipe and inflates the lining, causing it to expand and conform to the inner wall of the pipeline. Subsequently, an external motor connected to one end of the pull rope drives the pull rope to move. After the pull rope passes around the rollers inside the mounting frame, it drives the curing device connected to the end connector to move along the inside of the lining, completing the curing and repair work of the lining.

[0003] However, existing rope traction devices for pipeline lining repair have significant shortcomings in practical use, particularly in terms of support and balance adjustment. Most existing devices lack dedicated stable support components, relying solely on the simple support structure of the mounting frame itself or temporary manual fixing for positioning. Furthermore, they lack components for precisely adjusting the balance of the mounting frame. When the work site is uneven, the mounting frame is prone to tilting to the left or right, failing to maintain a horizontal position. This instability in support and lack of balance adjustment directly leads to insufficient overall installation stability, causing subsequent misalignment of core components. For example, the rollers around the pull rope may deviate due to the mounting frame's tilt, causing the rope to easily shift or become entangled during movement, hindering stable traction of the curing equipment. The connecting sleeve may also deviate from its preset position due to the mounting frame's tilt, affecting the sealing effect after the lining is installed and increasing the risk of gas leakage during inflation, thus affecting the lining's expansion and adhesion to the pipeline wall. Ultimately, the curing equipment cannot move evenly within the lining, resulting in uneven curing and severely impacting the precision of pipeline lining repair operations, failing to meet the quality requirements of pipeline repair. Utility Model Content

[0004] The problem this invention aims to solve is to provide a rope traction device for pipe lining repair. In the support assembly of this invention, the symmetrically arranged unfolding frames can unfold outward and insert into the soil under the action of the potential energy released by the torsion springs, thus providing initial support for the mounting frame. In conjunction with the lifting screw threaded to the mounting frame, the position of the mounting frame can be adjusted, keeping the mounting frame in a balanced state and avoiding a situation where the left side is higher than the right side. This ensures that the entire device is installed firmly and in a horizontal state, preventing the subsequent working positions of each component from shifting due to the tilt of the mounting frame, and ensuring the accuracy of subsequent pipe lining repair operations.

[0005] The technical solution provided by this utility model to solve the above problems is as follows: a pipe lining repair rope traction device, including a mounting frame, a connecting sleeve, a sealing ring, an air inlet pipe, a roller, a pull rope, and a connector. The connecting sleeve is installed at the lower part of the mounting frame, the sealing ring is installed on the outer wall of the connecting sleeve, the air inlet pipe is installed on the mounting frame, and the end of the air inlet pipe is connected to the connecting sleeve. The roller is rotatably connected to the inside of the mounting frame, the pull rope passes through the connecting sleeve and is wound around the roller, the connector is installed at the end of the pull rope, the other end of the pull rope is connected to an external motor, and the connector is located inside the connecting sleeve. It also includes a support assembly for supporting the mounting frame.

[0006] More preferably, the sealing ring can be stretched and deformed to tighten and secure the lining.

[0007] More preferably, the connector is used to connect to an external curing device.

[0008] More preferably, the support assembly includes an unfolding frame, a torsion spring, a stop bar, and a lifting screw. The symmetrically arranged unfolding frames are rotatably connected to the mounting frame. The torsion spring connects the unfolding frame and the mounting frame. The stop bar is rotatably connected to the mounting frame and is used to limit the unfolding frame. The lifting screw is threadedly connected to the mounting frame.

[0009] More preferably, the upper part of the blocking rod is a semi-circular plate.

[0010] More preferably, the lifting screw is used to adjust the position of the mounting bracket so that the mounting bracket can remain in a balanced state and will not be higher on the left and lower on the right.

[0011] Compared with the prior art, the advantages of this utility model are: In the support assembly of this utility model, the symmetrically arranged unfolding frame can unfold outward and insert into the soil under the action of the potential energy released by the torsion spring, so as to achieve the initial support for the installation frame. With the help of the lifting screw threaded to the installation frame to adjust the position of the installation frame, the installation frame can be kept in a balanced state, avoiding the situation of left higher than right, thereby ensuring that the whole device is installed firmly and in a horizontal state, preventing the subsequent working position of each component from shifting due to the tilt of the installation frame, and ensuring the accuracy of the subsequent pipeline lining repair work.

[0012] The sealing ring on the outer wall of the connecting sleeve can be stretched and deformed. After the liner to be repaired is put on the connecting sleeve, the deformation of the sealing ring can tighten and fix the liner, thereby achieving a seal between the liner and the connecting sleeve. This effectively prevents gas from leaking from the connection between the two during subsequent inflation, providing a reliable guarantee for the smooth expansion of the liner.

[0013] The air inlet pipe on the mounting bracket is connected to the connecting sleeve. After connecting the air inlet pipe to an external inflation device, the gas can enter the connecting sleeve through the air inlet pipe and then enter the inner lining, causing the inner lining to gradually expand and fit against the inner wall of the pipe. In this way, the inner lining is first supported, which lays a good foundation for the subsequent curing and repair of the inner lining, ensuring that the inner lining can form a stable fit with the pipe after repair, and improving the sealing performance and structural stability of the repaired pipe.

[0022] Example: As shown in the attached drawings, a pipe lining repair rope traction device includes a mounting frame 1, a connecting sleeve 2, a sealing ring 3, an air inlet pipe 4, a roller 5, a pull rope 6, and a connector 7. The connecting sleeve 2 is installed on the lower part of the mounting frame 1, and the lining can be fitted onto the connecting sleeve 2. The sealing ring 3 is installed on the outer wall of the connecting sleeve 2 and can be stretched and deformed to tighten and fix the lining. The air inlet pipe 4 is installed on the mounting frame 1, and its end is connected to the connecting sleeve 2 for inflating the lining. The air inlet pipe 4 needs to be connected to an external inflation device. The roller 5 is rotatably connected to the inside of the mounting frame 1. The pull rope 6 passes through the connecting sleeve 2 and is wound around the roller 5. The roller 5 is used to limit and guide the pull rope 6. The connector 7 is installed at the end of the pull rope 6, and the other end of the pull rope 6 is connected to an external motor. The connector 7 is located inside the connecting sleeve 2 and is used to connect to an external curing device. It also includes a support assembly for supporting the mounting frame 1.

[0023] In this embodiment, the support components specifically include a deployment frame 8, a torsion spring 9, a blocking rod 10, and a lifting screw 11. The symmetrically arranged deployment frame 8 is rotatably connected to the mounting frame 1. When deployed, the deployment frame 8 can be inserted into the soil to support the mounting frame 1. The torsion spring 9 is connected between the deployment frame 8 and the mounting frame 1. Initially, the torsion spring 9 is in a charged state. The blocking rod 10 is rotatably connected to the mounting frame 1. The upper part of the blocking rod 10 is a semi-circular plate. The blocking rod 10 is used to limit the deployment frame 8. The lifting screw 11 is threadedly connected to the mounting frame 1. The lifting screw 11 is used to adjust the position of the mounting frame 1 so that the mounting frame 1 can maintain a balanced state and will not be higher on the left and lower on the right.

[0024] When performing pipeline lining repair work, the device is first installed and fixed. The blocking rod 10 connected to the mounting frame 1 is rotated. Since the blocking rod 10 originally limited the unfolding frame 8, the rotation of the blocking rod 10 releases the limitation on the unfolding frame 8. At this time, the torsion spring 9 connected between the unfolding frame 8 and the mounting frame 1 releases the initial stored potential energy, causing the unfolding frame 8 to unfold outward. After unfolding, the unfolding frame 8 is inserted into the soil, initially supporting the mounting frame 1. Then, the position of the mounting frame 1 is adjusted by the lifting screw 11 to keep the mounting frame 1 in a balanced state, so that it does not appear to be higher on the left and lower on the right. This process can ensure that the device is installed firmly and in a horizontal state, avoiding the subsequent displacement of the working position of each component due to the tilt of the mounting frame 1, and ensuring the accuracy of subsequent repair work. Next, the liner to be repaired is fitted onto the connecting sleeve 2 installed at the lower part of the mounting frame 1. Utilizing the stretchable and deformable characteristic of the sealing ring 3 installed on the outer wall of the connecting sleeve 2, the sealing ring 3 is adjusted and the liner is then tightened and fixed. This operation achieves a sealed fixation between the liner and the connecting sleeve 2, effectively preventing gas leakage from the connection point during subsequent inflation and ensuring smooth expansion of the liner. Then, the air inlet pipe 4 installed on the mounting frame 1 is connected to an external inflation device. The external inflation device is started, and gas enters the connecting sleeve 2 connected to its end through the air inlet pipe 4, and then enters the fitted liner through the connecting sleeve 2, causing the liner to gradually expand and adhere to the inner wall of the pipe. This step, through inflation, ensures close contact between the liner and the inner wall of the pipe, laying a good foundation for subsequent liner curing and repair, ensuring that the repaired liner can form a stable, fitted structure with the pipe. After the lining expansion is completed, the connector 7 is passed through the lining and connected to the external curing equipment. Since the pull rope 6 passes through the connecting sleeve 2 and is wrapped around the roller 5, and the other end of the pull rope 6 is connected to the external motor, after the external motor is started, the motor drives the pull rope 6 to move in the set direction. The roller 5 plays a limiting and guiding role during the movement of the pull rope 6, preventing the pull rope 6 from deviating or tangling. When the pull rope 6 moves, it simultaneously drives the connector 7 and the external curing equipment to move along the connecting sleeve 2 and inside the expanded lining. This process achieves uniform movement of the curing equipment inside the lining through the stable traction of the pull rope 6, ensuring that the curing equipment can perform comprehensive and uniform curing treatment on the lining, significantly improving the quality of pipeline lining repair. At the same time, the guiding role of the roller 5 can also reduce the friction and wear of the pull rope 6 during movement, extend the service life of the pull rope 6, and ensure the continuity and stability of the entire traction process.

[0025] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
