[0002] At present, there are many pipelines buried underground that are intertwined and complicated. Some pipelines have caused accidents after years of use. Most of these pipelines are laid in densely populated and prosperous commercial areas. Excavation and construction will cause traffic jams and damage to green spaces and gardens. Therefore, people have produced a pipeline repair formwork device.

[0003] However, when most of the pipeline repair formwork devices are put into use, they need to repair pipelines of different widths, so arc plates of different angles need to be installed on the device. Most of the repair formwork devices are installed with screws and nuts. The installation steps are relatively cumbersome, and the staff need to manually support the arc plates during installation, which not only increases the workload of the staff, but also reduces the speed of pipeline repair.

[0004] At the same time, most of the repair formwork devices will be subjected to reaction force during repair, and this reaction force acts on the device itself. When the reaction force is large, it is easy to cause certain damage to the device, thereby reducing the service life of the device. Utility Model Content

[0023] See also Figure 1-5 As shown, a pipeline repair formwork device includes a locomotive component 1. The locomotive component 1 can move the device in the pipeline to a position that needs to be repaired and can support the upper part of the device. A hydraulic rod 2 is fixed on the top of the locomotive component 1. The hydraulic rod 2 can provide power for the device when repairing. The number of hydraulic rods 2 is three and they are symmetrically designed with the central axis of the locomotive component 1. With the increase in number, the speed of repairing the device can be accelerated. A connecting shell 3 is fixed on the top of the hydraulic rod 2. A slide groove 4 is opened inside the connecting shell 3. A fixed shell 7 is installed above the connecting shell 3, and a limiting mechanism 6 is installed in the inner cavity of the fixed shell 7. An arc plate 8 is installed above the fixed shell 7. Under the action of the hydraulic rod 2, the arc plate 8 can squeeze the protruding part of the inner wall of the pipeline to return the protruding part to its original position, so that the pipeline can be repaired. The cross-sectional shape of the arc plate 8 is an arc, and the top of the arc plate 8 is tightly fitted with the inner wall of the pipeline. Under the action of the angle of the arc plate 8, the device can repair the pipeline more comprehensively. A card slot 9 is opened inside the arc plate 8, and the card slot 9 and the limiting mechanism 6 and the fixed shell 7 are used in conjunction with each other. With the cooperation of the connecting shell 3 and the slide groove 4, the fixed shell 7 can be moved from the surface of the slot 9 to the inside of the arc plate 8. At the same time, with the cooperation of the limiting mechanism 6 and the slot 9, the arc plate 8 can be fixed on the top of the device, which is convenient for the staff to replace the arc plate 8 and reduces the labor of the staff, thereby increasing the practical effect of the device. The inner cavity of the locomotive component 1 is installed with a moving mechanism 10, and the inner cavity of the locomotive component 1 is slidably connected with a support rod 11. A fixing block 12 is fixed at one end of the support rod 11. Under the action of the moving mechanism 10, the fixing block 12 can be moved to the surface of the inner wall of the pipeline through the support rod 11, so that the device is more stable when repairing the pipeline, and the force-bearing area of ​​the locomotive component 1 during repair is increased, which effectively prevents the device from being damaged due to excessive reaction force during repair, thereby increasing the service life of the device. The number of support rods 11 and the fixing block 12 is two and is symmetrically designed with the central axis of the locomotive component 1. With the increase in number, the device can be more stable when working.

[0024] The limiting mechanism 6 includes a limiting block 61, the surface of the limiting block 61 is slidably connected to the inner cavity of the fixed shell 7, a compression spring 62 is fixed to one side of the limiting block 61, one side of the compression spring 62 is fixedly connected to the inner cavity of the fixed shell 7, and a fixing rod 63 is fixed to the inner cavity of the fixed shell 7. With the cooperation of the slide groove 4 and the manual block 5, the limiting block 61 can be moved to the inside of the fixed shell 7, and the compression spring 62 is compressed at the same time, so that the fixed shell 7 moves to the inside of the arc plate 8 on the surface of the slot 9, and then under the action of the rebound of the compression spring 62, the limiting block 61 can be moved out of the interior of the fixed shell 7 and fit closely to the surface of the slot 9, so that the arc plate 8 can be fixed on the top of the device, which makes it convenient for the staff to replace the arc plate 8, reduces the labor of the staff, and thus increases the practical effect of the device. The surface of the fixing rod 63 is slidably connected with the inner cavity of the limit block 61. The limit block 61 is located at the center of the compression spring 62, which effectively prevents the compression spring 62 from being displaced during operation, increases the stability of the limit mechanism 6, and thus increases the stability of the device. A manual block 5 is fixed to the bottom of the limit block 61, and the surface of the manual block 5 is slidably connected with the inner wall of the slide groove 4. Under the action of the manual block 5, the staff can conveniently control the limit block 61.

[0025] The moving mechanism 10 includes a stepper motor 101, the bottom of which is fixedly connected to one side of the locomotive component 1, the output shaft of the stepper motor 101 passes through one side of the locomotive component 1 and is rotatably connected to the passing portion, the output shaft of the stepper motor 101 is fixedly provided with a bidirectional threaded rod 102, both sides of the surface of the bidirectional threaded rod 102 are threadedly connected with sliders 103, one side of the slider 103 is fixedly connected to the surface of the support rod 11, there are two sliders 103 and they are symmetrically designed with respect to the central axis of the locomotive component 1, under the action of the stepper motor 101, the bidirectional threaded rod 102 can drive the two sliders 103 to move in opposite directions at the same time, so that the slider 103 drives the fixed block 12 to move to the surface of the inner wall of the pipe through the support rod 11, so that the device can be more stable when repairing the pipe, and effectively prevents the device from being damaged due to excessive reaction force during repair, thereby increasing the service life of the device.

[0026] Working principle: First, the staff determines the angle of the curved plate 8. When the curved plate 8 needs to be installed on the top of the device, the staff can move the limit block 61 to the inside of the fixed shell 7 by moving the manual block 5 on the inner wall of the slide groove 4. At the same time, the limit block 61 compresses the compression spring 62. Then the staff connects the card slot 9 and the fixed shell 7 to each other, so that the fixed shell 7 moves to the inside of the curved plate 8. At the same time, under the action of the rebound of the compression spring 62, the limit block 61 can be moved out of the inside of the fixed shell 7 and fit tightly with the inner wall of the card slot 9, so that the curved plate 8 can be fixed on the top of the device. When the replacement is completed, the staff places the device inside the pipeline. When the device is moved to the bottom that needs to be repaired, the stepper motor 101 drives the two sliders 103 to move in opposite directions at the same time through the bidirectional threaded rod 102, so that the slider 103 drives the fixed block 12 to move through the support rod 11, and the fixed block 12 moves to the surface of the inner wall of the pipeline. When repair is needed, under the action of the hydraulic rod 2, the arc plate 8 can squeeze the protruding part inside the pipeline, and then the device can be moved out of the pipeline after the repair is completed.
