Specific embodiments

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] Please refer to Figures 1 - 5 , the present utility model provides a technical solution: an automatic formwork support device for pipeline repair, including: circular shell 1, first telescopic rod 2, driving wheel 3 and pushing mechanism 4;

[0028] The outside of the circular shell 1 is connected with the first telescopic rod 2, the end of the first telescopic rod 2 is connected with the driving wheel 3, and the inside of the circular shell 1 is provided with a pushing mechanism 4; a mounting mechanism 5 is arranged in the pushing mechanism 4, an arc-shaped plate 6 is connected above the mounting mechanism 5, an observation head 7 is connected to the front of the circular shell 1, a wireless controller 8 is connected to the front of the circular shell 1 near the observation head 7, a storage battery 9 is connected to the front of the circular shell 1 near the wireless controller 8, a second telescopic rod 10 is connected to the outside of the circular shell 1 far from the second one, and the end of the second telescopic rod 10 is connected with a driven wheel 11.

[0029] The driving mechanism 4 includes: a push plate 401, a guiding groove 402, a spiral plate 403, a circular plate 404, a driving motor 405 and a reduction gearbox 406. The push plate 401 slides through the inner wall of the circular shell 1. A guiding groove 402 is formed on the back of the push plate 401. A spiral plate 403 is slidably connected in the guiding groove 402. A circular plate 404 is fixedly connected to the back of the spiral plate 403. The back of the circular shell 1 is connected with a driving motor 405. The output end of the driving motor 405 is connected with a reduction gearbox 406. The reduction gearbox 406 is connected to the back of the circular shell 1, and the output end of the reduction gearbox 406 penetrates and rotates in the inner wall of the circular shell 1. The circular plate 404 is connected to the output end of the reduction gearbox 406.

[0030] During specific implementation, by starting the driving motor 405 to drive the gear set in the reduction gearbox 406 to rotate, the reduction gearbox 406 reduces the speed and increases the torque to drive the circular plate 404 to rotate. The circular plate 404 drives the front spiral plate 403 to rotate and slide in the guiding groove 402 in the push plate 401. When the spiral plate 403 rotates, it drives the four groups of push plates 401 to move simultaneously, driving the corresponding arc plates 6 to move synchronously, applying pressure to the sunken part of the pipeline to restore the sunken part of the pipeline. By using a set of driving motor 405 to drive the four groups of arc plates 6 to move simultaneously, the maintenance cost of the automatic formwork device is reduced.

[0031] Refer to Figure 1 、 Figure 2 and Figure 6 It can be known that the installation mechanism 5 includes: an L-shaped groove 501, a stopper 502, a T-shaped block 503, a through hole 504, an L-shaped rod 505, a push handle 506 and a spring 507. An L-shaped groove 501 is formed at the end of the push plate 401. A stopper 502 is fixedly connected to the inner wall of the L-shaped groove 501. A T-shaped block 503 is abutted above the stopper 502. The T-shaped block 503 is slidably connected in the L-shaped groove 501, and the T-shaped block 503 is fixedly connected to the bottom of the arc plate 6. A through hole 504 is formed in the T-shaped block 503. An L-shaped rod 505 is slidably connected in the through hole 504. One side of the L-shaped rod 505 is connected with a push handle 506. The push handle 506 slides through the inner wall of the L-shaped groove 501. One end of the L-shaped rod 505 away from the push handle 506 is connected with a spring 507. The spring 507 is connected to the inner wall of the L-shaped groove 501.

[0032] During specific implementation, the L-shaped rod 505 is driven to move by pressing the push handle 506, and the L-shaped rod 505 is pulled out from the through hole 504, and the spring 507 is compressed to release the limit on the T-shaped block 503. Then, the arc-shaped plate 6 is directly pulled to drive the T-shaped block 503 to be pulled out from the L-shaped groove 501. The T-shaped block 503 at the bottom of the arc-shaped plate 6 to be replaced is inserted into the L-shaped groove 501 and abuts against the stop block 502. Then, the push handle 506 is released, and the spring 507 pushes the L-shaped rod 505 to insert into the through hole 504. At the same time, the L-shaped rod 505 abuts against the stop block 502 to limit the T-shaped block 503 and fix the T-shaped block 503 in the L-shaped groove 501 to prevent the T-shaped block 503 from falling off from the L-shaped groove 501, thereby fixing the arc-shaped plate 6 and facilitating the quick replacement of the arc-shaped plate 6 of the automatic formwork support device.

[0033] In summary, when using the automatic formwork support device for pipeline repair, first, adjust the lengths of the four groups of first telescopic rods 2 to make the driving wheels 3 abut against the inner wall of the pipeline. The storage battery 9 provides power for the entire device. Observe the internal situation of the pipeline through the observation head 7. Remotely control the wireless controller 8 to start the motors near the two groups of first telescopic rods 2 below to drive the driving wheels 3 to rotate and drive the entire device to move inside the pipeline. When moving to the sunken part, start the driving motor 405 to drive the arc-shaped plate 6 to move and squeeze the sunken part to restore it. When the arc-shaped plate 6 is deformed or worn after long-term use, install the push handle 506 to remove and replace the arc-shaped plate 6.
