AI Technical Summary
Existing trenchless pipeline lining repair devices have a small contact area between the support plate and the inner wall of the pipeline during use. This requires rotating the worm gear sequentially, which is time-consuming and laborious, and can easily lead to excessive local pressure that damages the inner wall of the pipeline.
The support mechanism, which adopts a synchronous expansion structure, includes components such as threaded columns, transmission discs, rotating plates, abutment plates, slide rails, and abutment blocks. Through the cooperation of the transmission discs and rotating plates, the abutment plates can be quickly expanded to contact the inner wall of the pipe, and the abutment blocks can increase the contact area and disperse stress.
It enables the rapid deployment of the contact plate, saving time and effort, reducing pressure per unit area, avoiding localized damage to the inner wall of the pipeline, and improving the ease of use and safety of the device.

[0022] In actual implementation, in the process of using the trenchless pipeline lining repair traction device, in order to quickly deploy the abutment plate 404 to make it contact with the inner wall of the pipeline, the threaded column 401 is first rotated to generate a pushing force on the transmission disc 402, so that the transmission disc 402 moves away from the fixed seat 411. Because the transmission disc 402 and the rotating plate 403 are rotationally connected, the movement of the transmission disc 402 drives the rotating plate 403 to rotate. At this time, the angle between the rotating plate 403 and the transmission disc 402 changes, thereby generating a pushing force on the abutment plate 404, so that the abutment plate 404 moves away from the base 3. Because the abutment plate 404 is connected with the fixed rod 409, the fixed rod 409 slides along the fixed column 408 at this time, thereby guiding the movement of the abutment plate 404 to move stably. At this time, the compressed spring 410 resets to generate an elastic force to assist the movement of the abutment plate 404. Until the abutment plate 404 contacts with the inner wall of the pipeline to support, the abutment plate 404 is deployed at the same time, without rotating the worm in sequence, the deployment of the abutment plate 404 is completed, saving time and effort.
[0023] Because the abutment plate 404 is connected with the abutment block 406 through the sliding rail 405, the threaded pin 407 can be disconnected with the sliding rail 405 in advance, thereby canceling the limiting of the sliding rail 405. Then, the abutment block 406 is moved to make the sliding rail 405 slide along the abutment plate 404. Until the abutment block 406 moves to the specified position, the threaded pin 407 is rotated and inserted into the sliding rail 405, thereby limiting the sliding rail 405 to prevent it from moving randomly. At this time, through the cooperation of the abutment block 406 and the abutment plate 404, the contact area between the abutment assembly and the inner wall of the pipeline is increased, thereby reducing the unit area pressure and dispersing the contact stress to avoid stress concentration, preventing the inner wall of the pipeline from being damaged due to excessive local pressure.
[0024] Because the threaded column 401 is connected with the threaded rod 412 through the fixed seat 411, the outer wall of the threaded rod 412 is threadedly connected with the threaded cylinder 413. The threaded cylinder 413 is first rotated downward. At this time, the total length of the threaded rod 412 and the threaded cylinder 413 increases, thereby generating a pushing force on the base 414, so that the base 414 moves downward and contacts with the ground. Then, the support rod 415 is rotated to penetrate the base 414 and is inserted into the ground, thereby fixing the base 414 to increase the fixing effect between the base 414 and the ground. At this time, the threaded column 401 is assisted and supported by the fixed seat 411, which facilitates the rotation of the threaded column 401 and the deployment of the abutment plate 404 at the same time. Therefore, when the trenchless pipeline lining repair traction device is used, it plays a role in facilitating the simultaneous deployment of the abutment assembly and dispersing the contact stress.
[0025] In summary, the non-excavation pipeline lining repair traction device with synchronous expansion structure is used, the pipeline repair device is moved into the pipeline to be repaired in advance, then the base 3 is fixed through the abutment plate 404, the servo motor on the outer wall of the winding box 1 is started, the winding box 1 winds the traction rope 2, then the traction rope 2 is wound to pull the repair device in the pipeline to move, and then the repair device is assisted to position and adhere the lining material on the inner wall of the pipeline, so that the repair and reinforcement of the pipeline are realized, which is the prior art and will not be described in detail here. The support mechanism 4 expands the abutment plate 404 at the same time to make it contact with the inner wall of the pipeline for support, then the expansion work of the abutment plate 404 can be completed without rotating the worm in sequence, time and effort are saved; and through the cooperation of the abutment block 406 and the abutment plate 404, the contact area of the abutment assembly and the inner wall of the pipeline is increased, so that the unit area pressure is reduced, the contact stress is dispersed to avoid stress concentration, so that the local high pressure of the inner wall of the pipeline is prevented from causing damage to the inner wall of the pipeline. The contents not described in detail in the description belong to the prior art known to those skilled in the art.
[0026] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
