Description

Technical Field

[0001] The present invention relates to the technical field of pipe support, and in particular to a pipe support device for pipe jacking construction. Background Art

[0002] Pipe jacking construction is a commonly used construction method for underground pipeline laying, and is widely used in the laying of urban water supply, drainage, gas supply, communication and other pipelines. Its principle is to horizontally drill underground and use a pipe jacking machine to push the pipeline into a predetermined underground passage. Due to the characteristics of pipe jacking construction, the pipeline usually needs to enter the underground space through drilling or underground channels, and this process has high technical difficulty and great construction risks. Especially when passing through rock or soft soil layers, the pipeline needs to bear great external pressure, and at the same time is affected by factors such as soil, groundwater, and settlement. During the construction process, problems such as pipeline offset, tilt, and breakage may occur. Therefore, it is particularly important to ensure the stability and accuracy of the pipeline.

[0003] Thus, pipe support plays a crucial role in pipe jacking construction. The function of the pipe support device is to provide support and positioning for the pipeline, prevent the pipeline from deforming, offsetting or breaking during construction, and ensure that the pipeline can steadily advance along the predetermined path. The pipe support device can effectively disperse the external pressure and maintain the stability of the pipeline during the process of entering the hole or advancing. However, although the existing pipe support devices have certain adjustment functions, they have certain defects in the precise positioning at the initial stage of pipe jacking construction.

[0004] For example, after the existing pipe support device is connected to the pipe, it usually needs to be adjusted through multiple manual operations to ensure the accurate docking of the pipe. However, due to the lack of an initial reference line, its positioning is often not precise enough. Therefore, whenever a pipeline is installed, it needs to be continuously calibrated and corrected. This method that relies on manual experience and measuring tools is difficult to ensure that each adjustment can achieve the ideal positioning effect, and the overall efficiency is low, affecting the construction efficiency. At the same time, when making adjustments, small offsets may occur, resulting in the pipeline not being in an ideal position. Therefore, the present invention proposes a pipe support device for pipe jacking construction to solve the problems existing in the prior art. Summary of the Invention

[0005] Aiming at the above problems, the purpose of the present invention is to propose a pipe support device for pipe jacking construction, which has the advantages of improving the pipe positioning accuracy and construction efficiency, and can solve the problems existing in the prior art.

The adjusting support ring is provided with positioning jacks, and the number and position of the positioning jacks correspond to those of the positioning slots. A second plug post is installed on the positioning jack, and one end of the second plug post is connected to the positioning slot. A positioning component is installed on the adjusting support ring, and a monitoring component is installed on the positioning support ring.

[0007] A further improvement lies in that: both the positioning support ring and the adjusting support ring are composed of a lower ring shell, an upper ring shell and an inner ring body. The lower ring shell and the upper ring shell are fixed by bolts, and slots are provided on the inner sides of the lower ring shell and the upper ring shell. Several groups of slots are evenly provided. Blocks are installed on the outer side of the inner ring body, and the number and position of the blocks correspond to those of the slots.

[0008] A further improvement lies in that: the positioning component includes laser sensors. Several groups of laser sensors are evenly provided, and the detection ends of the laser sensors face the positioning support ring. Laser induction points are provided on the positioning support ring, and the number and position of the laser induction points correspond to those of the laser sensors.

[0009] A further improvement lies in that: the monitoring component includes arc-shaped patches. Several groups of arc-shaped patches are evenly provided, and arc-shaped wear-resistant pieces are installed on the inner sides of the arc-shaped patches through rubber pads. A pressure sensor is provided between the rubber pad and the arc-shaped wear-resistant piece, and the sensing end of the pressure sensor contacts the arc-shaped wear-resistant piece.

[0010] A further improvement lies in that: distance sensors are installed on the inner side of the positioning support ring. Several groups of distance sensors are provided. The distance sensors are located between two adjacent arc-shaped patches, and the sensing ends of the distance sensors face the center of the positioning support ring.

[0011] A further improvement lies in that: arc-shaped support blocks are installed on the inner side of the adjusting support ring. Several groups of arc-shaped support blocks are evenly provided, and universal ball bearings are installed on the arc-shaped support blocks. Several groups of universal ball bearings are provided.

[0012] A further improvement lies in that: guiding slide bars are installed on the inner side of the annular bracket, there are several groups of the guiding slide bars, two connecting seats are arranged on the inner side of the annular bracket, and the connecting seats move on the guiding slide bars. The two connecting seats are respectively connected to the X-axis servo linear modules and two mounting seats on both sides.

[0013] A further improvement lies in that: limiting tracks are installed on both sides above the annular bracket, threaded holes are provided on the limiting tracks, and several groups of the threaded holes are evenly arranged.

[0016] The beneficial effects of the present invention are as follows: (1) Through the precise docking of the positioning support ring with the hole, the present invention provides a precise initial positioning reference for the pipe jacking construction. Thus, through precise docking, it is ensured that the pipe can accurately align with the hole at the initial stage, avoiding the problems of pipe deviation or inclination caused by inaccurate positioning in the traditional method. It not only improves the initial positioning accuracy of the pipe but also ensures the stability of the pipe during the pipe jacking construction. Further, taking the positioning support ring as the reference, no matter how the position of the adjusting support ring changes, its positioning reference remains unchanged. Thus, rapid and accurate repositioning can be carried out through the positioning support ring to ensure that the pipe can be accurately and smoothly pushed forward.

[0017] (2) The monitoring component is integrated on the positioning support ring of the present invention, and the monitoring component is used to monitor the pipe in real time during the pipe jacking construction, facilitating the operator to make corresponding adjustments according to the real-time data fed back by the monitoring, improving the safety and accuracy of the pipe jacking construction, and avoiding the problem of error accumulation that may occur during the pipe pushing process due to the lack of a real-time monitoring mechanism in the traditional technology.

[0018] (3) Through the innovative design of the positioning support ring and the adjusting support ring, the present invention greatly simplifies the pipe positioning process. Compared with the traditional support device that focuses on support and adjustment, the present invention improves the accuracy and construction efficiency of pipe positioning by simplifying the positioning process. Thus, through this design, the pipe positioning process is significantly simplified, not only saving a large amount of time but also reducing manual errors and improving the construction accuracy.

[0028] In order to deepen the understanding of the present invention, the following will further describe the present invention in detail in conjunction with embodiments. These embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0029] In the prior art, after the pipe support device is connected to the pipeline, manual intervention is usually required to adjust it to ensure accurate positioning of the pipeline. Due to the complexity and uncertainty of the construction site, such as soil loosening, geological condition changes, etc., the positioning support device will not immediately enter the precise docking position after being connected to the pipeline. The manual adjustment process usually relies on the experience and intuition of the operator rather than precise mechanical or electronic control. This leads to a problem: even if the pipeline and the support device are finally docked to the hole, the position of the pipeline may still have a slight deviation or inaccurate alignment, thus affecting the normal advancement of the pipeline.

[0030] In the existing support device, after the pipeline is connected to the support device, multiple steps are usually required to ensure the docking accuracy of the pipeline. The complexity of the adjustment process makes the construction period longer and requires multiple manual calibrations. After each adjustment, the operator needs to repeatedly check the position of the pipeline until it is confirmed that the pipeline is aligned with the hole. This repeated checking and adjustment not only increases the construction time but also results in a reduction in the overall construction efficiency.

[0031] Therefore, according to Figures 1 - 8 As shown, this embodiment proposes a pipe support device for pipe jacking construction, including a support base 1. Above the support base 1, an annular bracket 2 is installed through a bracket. On both sides (left and right sides) inside the annular bracket 2, an X-axis servo linear module 3 is installed, which can provide stable and high-precision left and right displacements. As Figure 4 shown, specifically, two groups of installation cavities are distributed inside the annular bracket 2 for installing the X-axis servo linear module 3. Above the annular bracket 2, there are two groups of mounting seats 4, and the two groups of mounting seats 4 are respectively connected to the X-axis servo linear modules 3 on both sides. Specifically, a guiding slide bar 27 is installed inside the annular bracket 2. There are several groups of guiding slide bars 27. In this embodiment, two groups of guiding slide bars 27 are symmetrically arranged. Inside the annular bracket 2, there are two groups of connecting seats 28, and the connecting seats 28 move on the guiding slide bar 27, that is, the guiding slide bar 27 penetrates through the connecting seats 28. The function of the guiding slide bar 27 is to provide a stable track system to ensure the stability of the connecting seats 28 during movement. The corresponding two groups of connecting seats 28 are respectively connected to the X-axis servo linear modules 3 on both sides and the two groups of mounting seats 4. Thus, under the action of the X-axis servo linear modules 3 on both sides, the mounting seats 4 can be driven to move on the guiding slide bar 27, and then the positions of the subsequent positioning support ring 7 and the adjusting support ring 8 can be adjusted respectively. Then, in this device, the positioning support ring and the adjusting support ring can be accurately adjusted according to actual needs.

[0032] On both sides above the annular bracket 2, limit tracks 29 are installed, and the length of the limit tracks 29 corresponds to the length of the annular bracket 2. As Figure 6As shown, threaded holes 30 are provided on the limit track 29, and several groups of threaded holes 30 are evenly arranged. The limit track 29 is connected to the mounting base 4 through the first slider 31, and the first slider 31 is connected to the threaded hole 30 through a bolt. After the position of the mounting base 4 is adjusted, the threaded holes 30 at the corresponding positions are threadedly connected by installing bolts, so as to fix the first slider 31. The first slider 31 is fixedly connected to the mounting base 4, thus ensuring the stability of the mounting base 4 after the position adjustment and avoiding displacement or instability caused by vibration or external force. Correspondingly, the cooperation between the first slider 31 and the limit track 29 improves the stability of the mounting base 4 during the movement process, providing a strong guarantee for the subsequent pipe positioning and support.

[0033] It should be noted that Figure 1 as the reference, the X-axis is in the front-back direction, the Y-axis is in the left-right direction, and the Z-axis is in the up-down direction.

[0034] Y-axis servo linear modules 5 are installed on both groups of mounting bases 4, which can provide stable and high-precision left-right displacement. A ring base 6 is installed on the Y-axis servo linear module 5. Correspondingly, a support track 32 is installed on the mounting base 4, and the ring base 6 is fixedly connected to the support track 32 through the second slider 33. Through the Y-axis servo linear module 5, the mounting base 4 can move in the left-right direction to meet the needs of the pipe during the pipe jacking construction process. The cooperation between the support track 32 and the second slider 33 ensures the stability of the ring base 6 during movement. Specifically, the length of the second slider 33 is adapted to the length of the support track 32. Thus, when the ring base 6 moves left and right (the bottom of the middle position of the ring base 6 is connected to the moving end of the Y-axis servo linear module 5), the second slider 33 can be connected and contacted with the support track 32, ensuring its support performance.

[0035] Z-axis lifting components are installed on both groups of ring bases 6, and a positioning support ring 7 and an adjustment support ring 8 are respectively installed on the two Z-axis lifting components. The function of the Z-axis lifting component is to ensure that the pipe can maintain the correct height during the pipe jacking construction process. Therefore, this device can be suitable for pipe jacking construction at different positions within a certain range. Specifically, the Z-axis lifting component includes servo electric push rods 34. There are two groups of servo electric push rods 34 symmetrically arranged, and the servo electric push rods 34 are connected to the ring base 6 through brackets. There are installation openings on the ring base 6 for installing the servo electric push rods 34. Correspondingly, a fixed column 35 is installed at the telescopic end of the servo electric push rod 34, and the positioning support ring 7 and the adjustment support ring 8 are connected to the fixed column 35 at the corresponding positions through bolts. During operation, by starting the servo electric push rod 34, it pushes the corresponding positioning support ring 7 and adjustment support ring 8 to move through its telescopic end. Correspondingly, two servo electric push rods 34 are installed on each ring base 6, and they are synchronously controlled by a main control servo driver.

[0036] The positioning support ring 7 is provided with plug post through holes 9 and positioning slots 10, and several groups of both the plug post through holes 9 and the positioning slots 10 are provided. In this embodiment, four groups of plug post through holes 9 are evenly arranged in the up, down, left, and right directions, and four groups of positioning slots 10 are also evenly arranged.

[0037] For the plug post through hole 9, a first plug post 11 is installed on the plug post through hole 9. As Figure 8 shown, after the device is aligned with the hole, the first plug post 11 (the insertion end of which is a tip) is used to pass through the plug post through hole 9, and then further penetrate into the soil layer near the hole. The pressure and friction of the soil layer are used to further stably position the positioning support ring 7. In this way, the positioning support ring 7 can establish a firm physical connection with the surrounding soil layer, ensuring that the pipeline can be accurately butted in the initial stage and remain stable during the construction process. Correspondingly, the contact between the plug post through hole 9 and the soil layer provides stronger mechanical stability, further improving the positioning support ring 7 not to displace or deviate during the pipe jacking construction process.

[0038] For the positioning slot 10, a positioning jack 12 is provided on the adjusting support ring 8, and the number and position of the positioning jacks 12 correspond to those of the positioning slots 10. A second plug post 13 is installed on the positioning jack 12, and one end of the second plug post 13 is connected to the positioning slot 10. One end of the second plug post 13 is connected to the positioning slot 10 by threads. Thus, after the position of the support ring 8 is determined, the position of the adjusting support ring 8 is adjusted. After the adjustment, the second plug post 13 is connected to the positioning slot 10 to strengthen the connection relationship between the adjusting support ring 8 and the positioning support ring 7, improving the overall stability of the device.

[0039] A positioning component is installed on the adjusting support ring 8. The positioning component includes laser sensors 19. Several groups of laser sensors 19 are evenly arranged, and the detection ends of the laser sensors 19 face the positioning support ring 7. Laser induction points 20 are provided on the positioning support ring 7, and the number and position of the laser induction points 20 correspond to those of the laser sensors 19. The laser induction points 20 are the target points detected by the laser sensors 19. At each laser induction point 20, the laser sensors 19 will receive laser reflection signals for calculating the distance from the positioning support ring 7. In this embodiment, eight groups of both the laser sensors 19 and the laser induction points 20 are provided. Specifically, the induction data of the laser sensors 19 are used to determine whether the adjusting support ring 8 and the positioning support ring 7 are in a parallel and horizontal state. Thus, after determining the initial positioning reference, through real-time laser data feedback, it is convenient to position the adjusting support ring 8, thereby reducing manual errors and improving the overall efficiency and stability of the construction.

[0040] A monitoring component is installed on the positioning support ring 7. Specifically, the monitoring component includes arc-shaped adhesive blocks 21. A number of groups of arc-shaped adhesive blocks 21 are evenly provided, and an arc-shaped wear-resistant sheet 23 is installed on the inner side of the arc-shaped adhesive block 21 through a rubber pad 22. A pressure sensor is provided between the rubber pad 22 and the arc-shaped wear-resistant sheet 23, and the sensing end of the pressure sensor contacts the arc-shaped wear-resistant sheet 23, which is used to measure the pressure between the pipeline and the positioning support ring 7 in real time. In this embodiment, four groups of arc-shaped adhesive blocks 21 are evenly provided. Specifically, the arc-shaped wear-resistant sheet 23 is in direct contact with the pipeline. Therefore, during operation, since the arc-shaped wear-resistant sheet 23 is in direct contact with the pipeline, the pressure exerted during the construction of the pipeline will be transmitted to the pressure sensor through the arc-shaped wear-resistant sheet 23. The pressure sensor feeds back the data to an external control device (this device has a main controller, which is the external control device and is electrically connected to all electronic components of this device). By sensing the contact pressure between the pipeline and the support ring, the pressure sensor can detect any pressure fluctuations caused by factors such as pipeline position changes, soil changes, and uneven pipeline stress. Thus, the operator can perform corresponding operations according to the monitored pressure value changes to avoid pipeline offset or damage caused by excessive or too small pressure. The need for manual intervention and frequent inspections is reduced throughout the process.

[0041] Furthermore, a number of distance sensors 24 are installed on the inner side of the positioning support ring 7. The distance sensors 24 are located between two adjacent arc-shaped adhesive blocks 21, and the sensing ends of the distance sensors 24 face the center of the circle of the positioning support ring 7. After the protective pipe (pipeline) is installed and during the pipe jacking construction process, the distance between the distance sensors 24 and the pipeline is sensed again. Specifically, each distance sensor 24 measures the distance between the pipeline and the positioning support ring 7 by emitting signals and receiving reflected signals. The sensing ends of the distance sensors 24 are located at the mid-axis position between the pipeline and the positioning support ring 7. Therefore, the relative position between the pipeline and the positioning support ring 7 can be accurately obtained. Thus, this device can detect the relative position between the pipeline and the support ring in real time to ensure that the pipeline is on an accurate track. When the pipeline position deviates or is misaligned, the distance sensors 25 will detect the change in distance and feed back the data to an external control device. Thus, in cooperation with the pressure sensor, the changes in the pipeline during the pipe jacking construction process can be detected in a timely manner to ensure the accuracy of the pipeline position.

[0042] The difference between the adjustable support ring 8 and the positioning support ring 7 is that an arc-shaped support block 25 is installed on the inner side of the adjustable support ring 8. There are several groups of arc-shaped support blocks 25 evenly arranged. In this embodiment, there are four groups of arc-shaped support blocks 25 evenly arranged, and universal ball bearings 26 are installed on the arc-shaped support blocks 25. There are several groups of universal ball bearings 26. Each group of arc-shaped support blocks 25 is evenly distributed with universal ball bearings 26 in a 5×5 array. After the pipeline passes through, the universal ball bearings 26 come into contact with the surface of the pipeline. The function of the universal ball bearings 26 is to reduce the friction between the pipeline and the positioning support ring 7 and improve the efficiency of pipeline propulsion. For its installation process, the pipeline is connected to the adjustable support ring 8 through an external hoisting device. After connection, the position of the pipeline is adjusted through the positioning of the adjustable support ring 8 and the positioning support ring 7. Then, one end of the pipeline is inserted into the positioning support ring 7. Finally, the external hydraulic pipe jacking device is connected to the pipeline for subsequent pipe jacking construction. During this process, once the pipeline is adjusted to the predetermined position through the adjustable support ring 8, the positioning support ring 7 will provide a fixed support point to ensure the stability of the pipeline during the entire construction process. When the pipeline is correctly installed, the distance sensor 24 and the pressure sensor will show a corresponding initial value. Based on the initial value, the changes during the pipe jacking construction process are observed.

[0043] Both the positioning support ring 7 and the adjustable support ring 8 are composed of a lower ring shell 14, an upper ring shell 15, and an inner ring body 16. The lower ring shell 14 and the upper ring shell 15 are fixed by bolts, and several groups of clamping grooves 17 are evenly arranged on the inner sides of the lower ring shell 14 and the upper ring shell 15. A clamping block 18 is installed on the outer side of the inner ring body 16. The number and position of the clamping blocks 18 correspond to those of the clamping grooves 17. In this embodiment, there are six groups of clamping grooves 17 evenly arranged, with three groups respectively in the lower ring shell 14 and the upper ring shell 15. Therefore, for the support rings (positioning support ring 7 and adjustable support ring 8) of this device, they can be easily disassembled. After installation, through the arrangement of the clamping grooves 17 and the clamping blocks 18, the situation of the inner ring body 16 rotating is avoided.

[0044] Then, for the detachable positioning support ring 7 and adjustable support ring 8, several groups of inner ring bodies 16 with different inner diameters can be preset. The outer diameters of the inner ring bodies 16 need to be kept the same, so as to adapt to the size adjustment of different pipelines. Correspondingly, when the inner diameter of the inner ring body 16 changes, the sizes of the corresponding components also need to be adjusted. This method makes this device have good expandability.
