Technical Field
[0001] This utility model relates to the field of underground pipeline technology, specifically to an underground pipeline repair device. Background Technology
[0002] Underground pipeline repair mainly includes two types: open-cut repair and trenchless repair. Trenchless repair does not obstruct traffic, does not damage green spaces or vegetation, and does not affect the normal life and work order of shops, hospitals, schools, and residents. It solves the problem of interference with residents' lives caused by traditional excavation construction, as well as the damage and adverse effects on traffic, environment, and the foundations of surrounding buildings. Therefore, it has high socio-economic benefits.
[0003] This utility model, disclosed in announcement number CN213361507U, relates to the field of pipeline repair technology and discloses an underground pipeline repair device, including a push plate. The lower part of the push plate is rotatably connected to the right end of a rotating shaft. The left end of the rotating shaft is provided with a fixed seat, and the outer side of the fixed seat is provided with cutting teeth. The upper end of the push plate is provided with guide rods on both the front and rear sides. The middle part of the guide rods is slidably connected to the upper end of the main body on both the front and rear sides. The middle part of the upper end of the push plate is rotatably connected to the right end of a screw rod. The middle part of the screw rod is threadedly connected to the main body. The lower part of the main body is provided with a clearance groove. The rear side of the clearance groove is provided with a second clamping plate. The front side of the main body is provided with a sliding rod. The front end of the sliding rod is fixedly connected to the upper part of a retaining edge. The lower part of the retaining edge is provided with a first clamping plate. This utility model applies to an underground pipeline repair device. By setting a freely movable first clamp in the device, the first clamp and the second clamp can fix the right end of the underground pipeline, making the clamping of the device more convenient. However, the above-mentioned pipeline repair structure is relatively simple. When using it, it is not possible to fix the two sets of pipelines horizontally on the right end, and it is not possible to adjust the fixed position of the pipeline as needed. Therefore, we propose an underground pipeline repair device. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-5 This utility model provides a technical solution: an underground pipeline repair device, including a mounting plate 1:
[0024] A telescopic rod 2 is provided at the middle of the lower surface of the mounting plate 1, and an injection head 3 is installed at the lower end of the telescopic rod 2. A connection port 4 is provided at the middle of the upper surface of the mounting plate 1. Positioning rods 5 are provided at both the front and rear ends of the mounting plate 1, and movable sleeves 6 are provided at both the left and right ends of the two sets of positioning rods 5. Positioning frames 9 are installed at the lower ends of the two sets of movable sleeves 6 on both sides, and fixing rings 10 are provided on the front side inside the two sets of positioning frames 9. Adjusting rods 11 are inserted into the rear end of the two sets of positioning frames 9, and clamping rings 12 are provided at the front end of the two sets of adjusting rods 11.
[0025] Four sets of movable sleeves 6 are respectively inserted at both ends of two sets of positioning rods 5, and each end of the two sets of positioning rods 5 is provided with a limit block. The position of the two sets of movable sleeves can be adjusted on the outside of the positioning rods, thereby adjusting the position of the positioning frame as needed and adjusting the fixed position of the pipeline. The limit block can effectively prevent the movable sleeves 6 from sliding or falling off during operation, thereby improving the stability and safety of the entire device.
[0026] Each of the four sets of movable sleeves 6 has a fixing bolt 7 on one side close to the other at the top. The upper surfaces of the two sets of positioning rods 5 are evenly provided with multiple sets of matching positioning grooves on the left and right sides. The design of the fixing bolt 7 and the positioning groove can effectively prevent the movable sleeve 6 from sliding or falling off during operation, thereby improving the stability and safety of the entire device. Through the cooperation of the fixing bolt 7 and the positioning groove, it can be ensured that the movable sleeve 6 stops moving at the predetermined position, thereby achieving precise control of the pipeline repair position and improving the repair accuracy.
[0027] Each of the four sets of fixing bolts 7 is fixedly installed with a return spring 8, and the lower end of each of the four sets of return springs 8 is connected to a moving sleeve 6. The return spring 8 can provide additional support and stability, preventing the moving sleeve 6 from sliding or falling off during operation, thereby improving the stability and safety of the entire device. When the external force is removed, the return spring 8 can help the moving sleeve 6 automatically return to its initial position, reducing the need for manual adjustment and improving operating efficiency.
[0028] The two sets of fixing rings 10 and the two sets of clamping rings 12 are all uniformly provided with multiple sets of protrusions. The design of the protrusions can increase the contact area between the fixing rings 10 and clamping rings 12 and the pipe surface, thereby improving the stability and safety of the entire device. This design helps to prevent slippage or detachment during operation.
[0029] Both sets of adjusting rods 11 have threaded structures on their outer sides, and both sets of positioning frames 9 have matching threaded holes at their rear ends. Each positioning frame 9 also has a positioning bolt at its rear end. Both sets of adjusting rods 11 have a handle 13 at their rear ends, and the two sets of adjusting rods 11 are rotatably mounted on the rear ends of the two sets of clamping rings 12. Each set of clamping rings 12 has a limit rod 14 at its upper end, and both sets of positioning frames 9 have matching sliding grooves on their upper inner sides. The threaded structures on the adjusting rods 11 and the threaded holes on the positioning frames 9 work together to achieve precise adjustment of the position of the clamping rings 12. This design allows operators to adjust the position of the clamping rings as needed to adapt to pipes of different sizes and shapes, thereby ensuring the accuracy and effectiveness of the repair work. The positioning bolts further fix the position of the adjusting rods 11, preventing misalignment during operation. During the process, the adjusting rod may move due to vibration or external force. This design improves the stability of the entire device and ensures the smooth progress of the repair process. The design of the handle 13 allows the operator to easily rotate the adjusting rod 11, thereby achieving a quick adjustment of the position of the clamping ring 12. This user-friendly design reduces the difficulty of operation and improves work efficiency. The setting of the limit rod 14 can limit the movement range of the clamping ring 12 and prevent it from moving excessively and damaging the pipeline or the device itself. This design plays a protective role and extends the service life of the device. By rotating the handle, the adjusting rod moves behind the positioning frame through the threaded structure. Then, the adjusting rod drives the clamping ring to move. Through the limit rod and the rotating clamping ring, the angle of the clamping ring can be prevented from tilting, and then the position of the clamping ring can be easily adjusted to clamp the pipeline.
[0030] Working principle: The position of the positioning frame is adjusted by adjusting the position of the moving frame outside the positioning rod. The moving frame is then fixed by the fixing bolt. Turning the handle moves the adjusting rod through the threaded structure, thereby driving the clamping ring. The clamping ring and the fixing ring fix the device. Then, the position of the telescopic rod is adjusted to connect the grouting device to the connection port. Grouting is then performed on the damaged parts of the pipe through the injection head.
