Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment for pipe jacking construction, specifically a pipeline deformation monitoring device during pipe jacking construction. Background Technology

[0002] Pipe jacking, also known as trenchless construction, is a pipeline installation technique that involves little or no excavation. In pipe jacking, the jacking force generated by jacking equipment within a working pit overcomes the friction between the pipe and the surrounding soil, pushing the pipe into the ground at a designed slope, and then removing the excavated soil. After one section of pipe is jacked into the soil, the second section is lowered and the jacking continues. The principle is based on the thrust generated by the main jacking cylinder and the pipe sections and intermediate sections, which propels the tool pipe or tunneling machine from the working pit through the soil to the receiving pit where it is lifted. The pipeline follows closely behind the tool pipe or tunneling machine, and is buried between the two pits.

[0003] Existing pipe jacking systems are prone to deformation under harsh construction conditions, which can lead to pipe bending, section damage, and even leaks at joints, causing unnecessary accidents. Therefore, new technical solutions are needed to address this issue. Utility Model Content

This device can solve the technical problem that pipe jacking can cause pipeline deformation under harsh construction environments, which may lead to pipe bending, pipe section damage, or even joint leakage, resulting in unnecessary accidents.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a pipeline deformation monitoring device is designed for the pipe jacking construction process, including a cylindrical body. A monitoring camera is installed in the middle of one end of the cylindrical body. Multiple adjustment slots are opened on both sides of the outer side of the cylindrical body. Bidirectional screw rods are rotatably connected in the multiple adjustment slots between the two sides of the cylindrical body. Adjustment blocks are slidably connected in the multiple adjustment slots. First connecting seats are installed on the multiple adjustment blocks. Support rods are rotatably connected to the inner side of the multiple first connecting seats through a rotating shaft.

[0006] The cylindrical body has second connecting seats installed on both sides of its outer surface. Support legs are rotatably connected to the inner sides of the second connecting seats via rotating shafts. Traveling wheels are rotatably connected to the support legs via rotating shafts. A sliding groove is formed at one end of each support leg near the cylindrical body. A slider is slidably connected in the sliding groove. A third connecting seat is installed on each slider. The other end of each support rod is rotatably connected to the inner side of each third connecting seat via rotating shafts. A servo motor is installed at one end of each support leg. The drive end of each servo motor is connected to the travel wheels.

[0007] Preferably, a circular groove is provided at the end of the cylindrical body away from the monitoring camera, a circular hole is provided in the circular groove, a battery, a processor and a wireless transceiver are installed in the circular hole, and a circular cover is provided in the circular groove.

[0008] Preferably, a drive motor is rotatably connected to the center of the circular cover, a connecting plate is installed on the drive end of the drive motor, three fixing rods are installed on the outer side of the connecting plate, a drive gear ring is installed between the outer ends of the three fixing rods, and multiple driven gears are rotatably installed on the end of the cylindrical body near the cover, and the multiple driven gears are respectively connected to multiple bidirectional lead screws, and the multiple driven gears mesh with the outer side of the drive gear ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model combines a servo motor, traveling wheels, a cylindrical body, an adjusting groove, an adjusting block, a support rod, a first connecting seat, a second connecting seat, a third connecting seat, a support leg, a monitoring camera, a sliding groove, and a slider. By starting the servo motor, the traveling wheels rotate, driving the cylindrical body to move. This, in conjunction with the monitoring camera, captures real-time video of the inner wall of the jacking pipe. The video is then processed by a processor and transmitted wirelessly to a monitoring terminal (such as a mobile phone). Personnel can then observe whether the inner wall of the jacking pipe has deformed based on the video transmitted by the monitoring camera. Furthermore, the traveling wheels can be adjusted to contact the inner wall of jacking pipes of different sizes, thus facilitating the monitoring of the deformation of the inner wall of jacking pipes of different sizes and further improving the applicability of the monitoring device.

[0014] 2. This utility model combines a drive motor, a drive gear ring, a driven gear, a connecting disc, and a fixed rod. By starting the drive motor, the drive gear ring rotates, which in turn drives multiple bidirectional lead screws to rotate synchronously with the driven gear. This allows for the synchronous adjustment of multiple traveling wheels, thus facilitating the monitoring of the movement of the cylindrical body within the inner wall of the jacking pipe of different sizes.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: A pipeline deformation monitoring device during pipe jacking construction, see [link / reference] Figures 1 to 5 The system includes a cylindrical body 1, with a monitoring camera 11 installed at the center of one end of the cylindrical body 1. Multiple adjustment slots 2 are formed on both sides of the cylindrical body 1. A bidirectional lead screw 21 is rotatably connected to each of the multiple adjustment slots 2 between the two sides of the cylindrical body 1. Adjustment blocks 22 are slidably connected to each of the multiple adjustment slots 2. First connecting seats 23 are installed on each of the multiple adjustment blocks 22. Support rods 24 are rotatably connected to the inner sides of each of the multiple first connecting seats 23 via a rotating shaft. Second connecting seats 25 are installed on both sides of the cylindrical body 1. Support legs 26 are rotatably connected to the inner sides of each of the multiple second connecting seats 25 via a rotating shaft. Support rods 24 are rotatably connected to each of the multiple support legs 26 via a rotating shaft. A rotating shaft connects to a traveling wheel 29. Multiple support legs 26 have grooves 210 at their ends near the cylindrical body 1, and sliders 211 are slidably connected within these grooves. Each slider 211 has a third connecting seat 27 mounted on it. The other ends of multiple support rods 24 are rotatably connected to the inner sides of the third connecting seats 27 via a rotating shaft. Servo motors 28 are mounted at their outer ends, and their drive ends are connected to the traveling wheels 29. A circular groove 14 is formed at the end of the cylindrical body 1 furthest from the monitoring camera 11, and a circular hole 13 is formed within the groove 14. The device contains a battery 6, a processor 61, and a wireless transceiver 62. A circular cover 4 is installed inside the circular groove 14, with multiple bolts 41 threaded through it and connected to the inner cavity of the circular groove 14. The monitoring camera 11, processor 61, and wireless transceiver 62 are connected in series via a data cable. During operation, the cylindrical body 1 is placed inside the jacking pipe. Then, the servo motor 28 is activated to drive the walking wheels 29, moving the cylindrical body 1. This allows the monitoring camera 11 to capture real-time video of the inner wall of the jacking pipe, which is then processed by the processor 61 and transmitted to the monitoring camera 62 via the wireless transceiver 62. On the monitoring terminal (such as a mobile phone), personnel can observe whether the inner wall of the jacking pipe is deformed based on the video transmitted by the monitoring camera 11. By rotating the screw, the adjusting block 22 moves in the adjusting groove 2, which is rotatably connected between the first connecting seat 23 and the third connecting seat 27 in conjunction with the support rod 24. At the same time, the third connecting seat 27 is slidably connected in the sliding groove 210 through the slider 211 and rotatably connected to the inner side of the second connecting seat 25 by the support leg 26. This allows the walking wheel 29 to be adjusted to contact the inner wall of the jacking pipe of different sizes, thereby facilitating the monitoring of the deformation of the inner wall of jacking pipes of different sizes and further improving the applicability of the monitoring device.

[0023] For details, see Figure 2 and Figure 5A drive motor 5 is rotatably connected to the center of the round cover 4. A connecting plate 51 is installed on the drive end of the drive motor 5. Three fixing rods 52 are installed on the outer side of the connecting plate 51. A drive gear ring 53 is installed between the outer ends of the three fixing rods 52. Multiple driven gears 54 are rotatably installed on the end of the cylindrical body 1 near the cover. The multiple driven gears 54 are respectively connected to multiple bidirectional lead screws 21. The multiple driven gears 54 are all meshed with the outer side of the drive gear ring 53. By starting the drive motor 5, the drive gear ring 53 is driven to rotate, thereby cooperating with the driven gears 54 to synchronously drive the multiple bidirectional lead screws 21 to rotate. This allows for the synchronous adjustment of multiple traveling wheels 29, thus facilitating the monitoring of the movement of the cylindrical body 1 in the middle of the inner wall of the jacking pipe of different sizes.

[0024] Further, see Figure 1 A transparent cover 3 is provided on the outer side of the cylindrical body 1 near the monitoring camera 11. Multiple fixing bolts 31 pass through the transparent cover 3, and the multiple fixing bolts 31 are threaded to the surface of the cylindrical body 1. By setting the transparent cover 3, the monitoring camera 11 is protected without affecting the monitoring of the inner wall of the jacking pipe by the monitoring camera 11, thereby improving the service life of the monitoring camera 11.

[0025] It is worth noting that, see Figure 3 Multiple supplementary lights 12 are installed on one end of the cylindrical body 1 near the monitoring camera 11, and the multiple supplementary lights 12 are distributed in a circle on the outside of the monitoring camera 11. The supplementary lights 12 are set to provide supplementary lighting for the monitoring camera 11 when it is working, thereby improving the clarity of the video of the inner wall of the jacking pipe captured by the monitoring camera 11 and further improving the effect of jacking pipe deformation monitoring.
