Abstract
Description
Technical Field
[0001] This invention relates to the field of pipeline laying technology, and in particular to an automatic pipeline laying device for communication pipelines. Background Technology
[0002] To reduce environmental damage to cables and optical fibers and to provide stable channels for cable laying, maintenance, and capacity expansion, communication pipelines are typically pre-laid underground before cables and optical fibers are laid. However, traditional open-cut laying methods are prone to disrupting traffic, damaging existing pipelines, and are inefficient, making them unsuitable for complex scenarios such as crossing rivers and soft soil layers. Therefore, trenchless automated devices are gradually becoming the inevitable choice to replace traditional methods. Taking the slurry-balanced pipe jacking machine as an example, this device can effectively solve a series of problems when laying pipelines using the traditional open-cut method, including traffic disruption, damage to existing pipelines, and high subsequent repair costs. At the same time, it can significantly improve the efficiency and quality of automated communication pipeline laying. Therefore, this device has been widely used in the field of automated communication pipeline laying. Before automatically laying communication pipelines, existing slurry balance pipe jacking machines typically pre-assess the jacking thrust of the existing hydraulic system based on factors such as foundation resistance, pipeline parameters, and jacking distance. However, during the pipeline jacking process, due to factors such as changes in the stratum and mismatched grouting lubrication, situations such as "insufficient thrust leading to jacking stagnation" or "excessive thrust damaging equipment / pipelines" can easily occur, reducing the automatic laying effect of the device. To address these issues, we propose an automatic communication pipeline laying device. Summary of the Invention
[0003] The purpose of this invention is to solve the problems mentioned in the background art by providing an automatic communication pipeline laying device.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An automatic communication pipeline laying device includes a hydraulic device, a tunneling machine, a first pipeline, a second pipeline, and a fixing plate. The hydraulic device is equipped with a correction component to improve the accuracy of the communication pipeline connection, and an adjustment component to adaptively adjust the jacking thrust of the communication pipeline. The correction assembly includes a guide rail fixedly installed on the hydraulic equipment, and an adjustment mechanism is installed on the guide rail; The adjusting assembly includes a circular roller fixedly mounted on a hydraulic device, an adjusting component mounted on the circular roller, a push plate slidably mounted on the circular roller, multiple rods fixedly mounted on the hydraulic device, a rotating shaft passing through and rotatably mounted between adjacent rods, an inclined plate fixedly mounted on each rotating shaft, a transmission plate evenly distributed in a ring fixedly mounted on the push plate, two connecting rods fixedly mounted on each transmission plate, an inclined block cooperating with the corresponding inclined plate fixedly mounted between adjacent connecting rods, and a rotating mechanism mounted together between the rotating shafts.
[0005] Compared with existing technologies, the advantages of this invention are: 1. Before laying communication pipelines, the present invention, through the cooperation of limiting components and correction components, can help improve the docking accuracy between pipeline one and pipeline two, as well as between pipeline two and subsequent communication pipelines to be laid, thereby helping to improve the laying effect of the device on communication pipelines.
[0006] 2: Before laying communication pipelines, the present invention can adaptively adjust the jacking force of the device on the communication pipeline according to the laying requirements of the communication pipeline, which can help improve the applicability of the device. At the same time, by adjusting the components, the jacking force of the device on the pipeline can be adjusted in a timely and adaptive manner according to the resistance during the jacking process of the communication pipeline, which can help further improve the automatic laying effect of the device on the communication pipeline.

[0009] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0010] Reference Figures 1-18 An automatic communication pipeline laying device includes a hydraulic device 1, a tunneling machine 2, a first pipeline 3, a second pipeline 4, and a fixing plate 5. The hydraulic device 1 is equipped with a correction component 8 to improve the accuracy of the communication pipeline connection, and an adjustment component 9 to adaptively adjust the jacking thrust of the communication pipeline.
[0011] Before using this device to lay communication pipelines, working shafts and receiving shafts must be built at the starting and ending points of the construction, respectively. Then, the hydraulic equipment 1 and guide rail 7 are hoisted and fixed in the preset position in the working shaft using existing hoisting equipment. After that, the tunneling machine 2 is hoisted onto the guide rail 7 using existing hoisting equipment. Then, through the cooperation of the hydraulic equipment 1 and the tunneling machine 2, the tunneling machine 2 is pushed to drill along the preset axis. After the tunneling machine head 2 is pushed into place, the pipeline 3 is hoisted and placed on the guide rail 7 using existing hoisting equipment. In order to ensure the docking effect of the first section of the jacking pipe and the tunneling machine 2, laser positioning is usually used to calibrate the first section of the pipe and the axis of the tunneling machine 2 to ensure the docking effect of the two. After the connection between pipe 3 and tunneling machine 2 is completed, the continuous jacking of hydraulic equipment 1 will push pipe 3 to gradually "squeeze" into the cut soil space, and push tunneling machine 2 to continue to cut the soil along the preset axis. Then, as the pipe sections are connected, the communication pipeline can be continuously laid in the underground soil until tunneling machine 2 reaches the receiving well and completes the automatic laying of the last section of communication pipeline (this step is similar to the working principle of the existing slurry balance pipe jacking machine for automatic laying of communication pipeline).
[0012] Reference Figures 1-3 A limiting component 6 is provided on the fixed plate 5. The limiting component 6 includes a support plate 61 that is fixedly installed on the fixed plate 5 in an arc shape. A threaded rod 62 is rotatably installed through the support plate 61. A sliding frame is threadedly installed on the threaded rod 62. A limiting roller 63 is rotatably installed on the sliding frame.
[0013] After the hydraulic equipment 1 and the guide rail 7 are fixedly installed in the preset position, the fixing plate 5 can be fixedly installed on the working well side wall opposite to the hydraulic equipment 1 by multiple bolts on the fixing plate 5. This makes it easier to limit the position of the mobile communication pipeline by the limiting component 6, thereby improving the laying effect of the communication pipeline.
[0014] After the above-mentioned pipe 3 is connected to the tunneling machine 2, and before the pipe 3 is continuously pushed into the cut soil space, the position of multiple limiting rollers 63 can be adjusted according to the outer diameter of the pipe 3. If the pipe diameter of the pipe 3 is small, multiple threaded rods 62 are rotated in the forward direction in sequence to drive multiple sliding frames to bring the corresponding limiting rollers 63 closer to each other until the multiple limiting rollers 63 are in contact with the outer wall of the pipe 3 (the pipe sections that make up a communication pipe section are all the same size, that is, the pipe 3, the second pipe 4 and the subsequent communication pipe to be connected are all the same size and shape). The multiple limiting rollers 63 apply a certain squeezing force to it (the squeezing force applied to the pipe 3 by the multiple limiting rollers 63 is small, the purpose of which is to ensure that the movement of the pipe 3 and the subsequent pipe 4 and the pipe to be laid is limited, while also avoiding the situation where the frictional resistance of the pipe 3 and the second pipe 4 is increased when they are pushed forward due to the large squeezing force applied by the multiple limiting rollers 63, thus reducing the efficiency of the communication pipe laying).
[0015] Existing slurry-balanced pipe jacking machines face several challenges during automatic pipe laying. Firstly, uneven settlement or lateral pressure in underground strata (such as soft soil or sand layers) can cause communication pipes to shift due to uneven thrust and differences in ground friction. Secondly, communication pipes must maintain straightness and sealing to protect cables; pipe misalignment can lead to leaks at joints, cable damage from compression, and significantly increased difficulty in re-threading cables during subsequent maintenance. Therefore, using multiple limiting rollers (63) to restrict the movement of pipe 3 and subsequent communication pipes (including pipe 4) can improve the laying efficiency. Setting movement limits for pipelines can effectively reduce the additional pressure or loosening of the surrounding soil caused by the communication pipelines during the laying process. This can, to some extent, protect surrounding buildings and pipelines. In addition, limiting the movement of pipeline 3 can help improve the accuracy of the subsequent connection between pipeline 3 and pipeline 4, as well as the accuracy of the connection between pipeline 4 and subsequent low-lying pipelines, and improve the sealing performance between pipelines (if the sealing effect between pipelines is poor, after the pipeline is laid, impurities such as mud can easily enter the pipeline from the joint gaps between the pipelines, causing corrosion and damage to the cables and wires laid inside the pipeline).
[0016] Reference Figures 1-11 The correction component 8 includes a guide rail 7 fixedly installed on the hydraulic equipment 1 (the guide rail 7 can limit the height of the communication pipeline, ensuring that all communication pipelines are at the same height, which can improve the accuracy of the connection between pipelines to a certain extent), and an adjustment mechanism is installed on the guide rail 7.
[0017] The adjustment mechanism includes a placement box 83 fixedly mounted on the guide rail 7. Two threaded rods 85 are rotatably mounted through the placement box 83. Movable parts 86 are threadedly mounted on both threaded rods 85, and both movable parts 86 are slidably mounted on the placement box 83. Two adjusting plates 88 are fixedly mounted on both movable parts 86. Limiting rollers 89 that are evenly distributed in a linear pattern are rotatably mounted on both adjusting plates 88. A pushing component is mounted on the hydraulic device 1, and a driving component is mounted on the guide rail 7.
[0018] The pushing component includes a ring 81 fixedly installed on the hydraulic equipment 1. Two pushing rods 82 are fixedly installed on the ring 81. Two spring telescopic rods 810 are fixedly installed on each of the two pushing rods 82. A drive block 811 is fixedly installed between each of the two spring telescopic rods 810.
[0019] The driving component includes two fixed boxes 84 fixedly mounted on the guide rail 7. Each fixed box 84 has a limit frame 812 fixedly mounted on it. Each limit frame 812 has a slider 813 slidably mounted on it. Each slider 813 has a tooth condition 814 that mates with the corresponding driving block 811 fixedly mounted on it. Each threaded rod 85 has a rotating gear 87 that mates with the corresponding tooth condition 814 fixedly mounted on it.
[0020] Existing slurry-balanced pipe jacking machines, after hoisting each section of communication pipe to the upper end of the track using existing hoisting equipment, mostly rely on manual methods to adjust the position of the new pipe. However, due to human factors, the accuracy of the connection between the new pipe and the existing pipe is easily reduced, which reduces the sealing effect between the two pipes after connection. At the same time, if there is a slight deviation between the pipe joints, it will increase the stress at the joints. In severe cases, it may cause the pipe sections to "misalign," or even make it impossible to continue to complete the subsequent connection, requiring a stop to correct the deviation, thus reducing the laying effect and efficiency of the pipe. In addition, if the communication pipe is made of concrete, forcibly connecting two misaligned pipes can easily cause cracks at the joint due to uneven stress. If the communication pipe is made of plastic (such as PE material), it is easy to deform due to excessive jacking resistance, reducing the service life of the laid communication pipe.
[0021] Therefore, after the connection between pipe 3 and tunneling machine 2 is completed as described above, and hydraulic equipment 1 pushes pipe 3 into place, pipe 4 is hoisted onto guide rail 7. Then, hydraulic equipment 1 is started first. At this time, the operation of hydraulic equipment 1 will first drive the two push rods 82, multiple spring telescopic rods 810, and two drive blocks 811 to move to the right through ring 81 (in conjunction with...). Figure 9 and Figure 10(As shown in the direction), where the two driving blocks 811 are moved to the right by force, the thrust applied by the right end inclined surface of the corresponding tooth condition 814 to the left end inclined surface can push the corresponding tooth condition 814 to move to the right together. The driving force applied by the two tooth conditions 814 to the corresponding rotating gear 87 when they are moved to the right can drive the two rotating gears 87 to drive the corresponding threaded rod 85 to rotate. The two threaded rods 85 are rotated in opposite directions. (The two tooth conditions 814 are set above and below the corresponding rotating gear 87 respectively. The purpose is that when the two tooth conditions 814 are moved to the right by force, the driving force applied by the two tooth conditions 814 to the corresponding rotating gear 87 can drive the two rotating gears 87 to rotate relative to each other.)
[0022] When the two threaded rods 85 rotate relative to each other under force, the two moving parts 86 can drive multiple adjusting plates 88 and limiting rollers 89 to move closer to each other. At this time, if pipe 4 is not located in the middle position of guide rail 7 and is not aligned with hydraulic equipment 1 and pipe 3, such as when pipe 4 is placed to the right (e.g.) Figure 6 (As shown in the direction), at this time, the multiple limiting rollers 89 on the two right adjustment plates 88 will first contact the right side wall of the second pipe 4. Since the multiple limiting rollers 89 on the two left adjustment plates 88 are not in contact with the side wall of the second pipe 4 at this time, there is room for movement on the left side of the second pipe 4. Therefore, by applying a pushing force to the left to the second pipe 4 through the multiple limiting rollers 89 on the right, the second pipe 4 can be pushed to the left until the multiple limiting rollers 89 on the left contact the side wall of the second pipe 4. The second pipe 4 will then cooperate with the limiting rollers 89 on both sides to apply a certain squeezing force to it. In this way, the position of the second pipe 4 can be automatically corrected, improving the accuracy of the subsequent docking of the second pipe 4 with the first pipe 3 and the push plate 92 on the hydraulic equipment 1. This helps to improve the effect and efficiency of the device in laying communication pipelines.
[0023] When multiple limiting rollers 89 work together to correct the position of pipe 4, and the hydraulic equipment 1 continues to drive the ring 81, two push rods 82, multiple spring telescopic rods 810, and drive block 811 to move to the right, the pipe 4 limits the continuous movement of the multiple limiting rollers 89 and adjusting plate 88. That is, the pipe 4 limits the position of the two threaded rods 85 and two toothed conditions 814 through the multiple limiting rollers 89, which will cause the two drive blocks 811 to be continuously moved to the right under force (such as...). Figure 11 (In the direction shown), along the inclined plane that cooperates with the left end of the corresponding tooth condition 814, the two corresponding spring telescopic rods 810 are compressed and continuously moved upward until they move to the upper end of the corresponding tooth condition 814 (after the two driving blocks 811 have continuously moved to the right side of the corresponding tooth condition 814, the driving blocks 811 can be driven to move downward and reset under the elastic force of the corresponding spring telescopic rods 810).
[0024] To ensure the stability of the subsequent movement of pipe 24 under force, multiple limit rollers 2 89 can be configured to have a certain degree of elasticity. This is so that after the multiple limit rollers 2 89 have worked together to correct the position of pipe 24, when the hydraulic equipment 1 continuously drives the two drive blocks 811 to move to the right (e.g., ...), Figure 10 (As shown in the direction), at this time, the drive block 811, the corresponding tooth condition 814, and the threaded rod 85 will first drive the multiple limit rollers 89 to move closer to each other and tightly clamp the pipe 4 (at this time, the multiple limit rollers 89 are compressed). When the multiple limit rollers 89 cannot move further due to the reaction force applied to them by the pipe 4, the drive block 811 will move relative to the corresponding tooth condition 814 through the continuous operation of the hydraulic device 1. At this time, since the multiple limit rollers 89 have a certain elasticity, when the drive block 811 does not indirectly apply driving force to the corresponding threaded rod 85, the multiple limit rollers 89 can return to their original state under the action of automatic elasticity, that is, release the pipe 4. This can ensure that when the pipe 4 is moved by force in the future, the multiple limit rollers 89 will not hinder the movement of the pipe 4.
[0025] Simultaneously, the hydraulic device 1 and the push plate 92 continue to move to the right. When the push plate 92 contacts the left end of the second pipe 4 (when the position of the second pipe 4 is corrected by the correction component 8, the right side of the push plate 92 does not contact the left end of the second pipe 4), the continuous operation of the hydraulic device 1 allows the push plate 92 to first push the second pipe 4 to complete the docking with the first pipe 3, and then push the second pipe 4 into place. After that, the hydraulic device 1 can be driven to reset. After the hydraulic device 1 and the push plate 92 move and reset, the above operation can be repeated to correct the position of the remaining communication pipes to be laid and to automatically lay them.
[0026] Simultaneously, the hydraulic device 1 drives the ring 81, the two push rods 82, and the two drive blocks 811 to move to the left and reset (as shown in the image). Figure 9 (As shown in the direction) When the left ends of the two drive blocks 811 contact the right inclined surface of the corresponding tooth condition 814, the thrust applied by the drive blocks 811 to the corresponding tooth condition 814 can push the corresponding tooth condition 814 and the slider 813 to move to the left and reset (in conjunction with...). Figure 10 and Figure 11 (as shown in the direction), during this process, through the cooperation of two tooth conditions 814 with the corresponding rotating gear 87 and threaded rod 85, multiple adjusting plates 88 and limiting rollers 89 on both sides can be driven to move away from each other, thereby facilitating the cooperation of multiple limiting rollers 89 to correct the position of the subsequent communication to be laid.
[0027] When the two tooth conditions 814 are subjected to force, the corresponding sliders 813 move to the leftmost end of the corresponding limiting frame 812. At this time, the limiting frame 812 indirectly limits the movement of the corresponding tooth conditions 814 through the corresponding sliders 813, thus limiting the position of the two tooth conditions 814. When the two driving blocks 811 are subjected to force and continue to move to the left, they will move upward along the right end slope of the corresponding tooth condition 814 until the two driving blocks 811 move above the corresponding tooth condition 814. Afterward, through the continuous leftward movement of the driving blocks 811, under the elastic force of the two spring telescopic rods 810, the two driving blocks 811 can be driven to move downward and reset again. This facilitates the subsequent correction of the position of the pipeline to be laid by cooperating with the two driving blocks 811 and the correction component 8.
[0028] Reference Figure 1 , Figures 12-18 The adjusting assembly 9 includes a circular roller 91 fixedly mounted on the hydraulic device 1, an adjusting component mounted on the circular roller 91, a push plate 92 slidably mounted on the circular roller 91, multiple rods 94 fixedly mounted on the hydraulic device 1, a rotating shaft 95 passing through and rotatably mounted between adjacent rods 94, an inclined plate 96 fixedly mounted on each rotating shaft 95, a transmission plate 98 evenly distributed in a ring fixedly mounted on the push plate 92, two connecting rods 99 (both with force-bearing and retractable functions) fixedly mounted on each transmission plate 98, an inclined block 910 cooperating with the corresponding inclined plate 96 fixedly mounted between adjacent connecting rods 99, and a rotating mechanism jointly mounted between the rotating shafts 95.
[0029] The rotating mechanism includes rack rods 913 that are uniformly fixed in a ring on the push plate 92, and parallel shaft gears 912 that cooperate with the corresponding rack rods 913 are fixedly installed on the rotating shafts 95. Cylindrical cylinders 93 that are uniformly distributed in a ring are fixedly installed on the push plate 92, and rods 94 are all slidably installed through and on the corresponding cylinders 93. Limiting components are installed between the inclined plates 96.
[0030] The limiting component includes multiple round rods 911, and two adjacent round rods 911 are fixedly installed on the corresponding inclined blocks 910. Two limiting plates 97 are fixedly installed on each inclined plate 96, and each limiting plate 97 has a limiting opening that cooperates with the corresponding round rod 911.
[0031] Before automatically laying or jacking communication pipelines, existing slurry balance pipe jacking machines typically determine the jacking thrust of the existing hydraulic system based on factors such as the foundation resistance, pipeline parameters, and jacking distance. However, during the jacking process, factors such as the change of the stratum from soft soil to hard soil, insufficient grouting lubrication, and poor soil removal (e.g., the slurry pipe being blocked by large debris, causing increased pressure in the slurry chamber and increased resistance) can increase the jacking resistance of the pipeline. At the same time, if the stratum softens or encounters cavities (e.g., entering a silt layer), or if there is excessive grouting, the jacking resistance of the pipeline can easily decrease.
[0032] When the resistance to pipe jacking increases, if the resistance exceeds the thrust set by the existing jacking equipment, it will cause the pipe jacking to stop, or even cause the hydraulic system of the existing jacking equipment to leak due to continuous overload, or the pipe joints to crack due to uneven stress. When the resistance to pipe jacking decreases, the pipe is prone to "stall" due to inertia, which will cause the pipe axis to deviate (if the laid communication pipe is sensitive to elevation deviation, the deviation may affect the cable laying), reducing the overall laying accuracy of the pipe.
[0033] Although some existing slurry balance pipe jacking machines manually adjust the thrust of the hydraulic system based on on-site monitoring data (such as jacking speed and oil pressure gauge readings) during the laying of communication pipelines, human factors (such as work experience and judgment) can easily lead to over-adjustment or untimely adjustment of the thrust. At the same time, in order to improve the accuracy of pipeline jacking resistance detection, some existing slurry balance pipe jacking machines use sensors (such as jacking force sensors and torque sensors) to monitor resistance changes in real time and automatically adjust the jacking thrust of the hydraulic system in conjunction with the hydraulic system. However, this mode may also have problems such as sensor response lag or mismatch between preset parameters and actual strata (such as the default thrust increase being too fast in soft soil), resulting in untimely or over-adjustment of the thrust. It is also easy to cause extreme situations such as "insufficient thrust causing pipeline jacking to stop" or "excessive thrust damaging equipment / pipelines".
[0034] When the device needs to connect to and advance the communication pipeline, and the hydraulic equipment 1 moves its upper drive plate to the right, i.e., closer to the pipeline, the hydraulic equipment 1 will transmit the thrust it generates to multiple inclined plates 96 through the cooperation of its upper drive plate, multiple rods 94, and multiple rotating shafts 95. At this time, the inclined plate 96 will "push" against the corresponding inclined block 910, applying a normal force N perpendicular to the inclined plane (the direction of the force: perpendicular to the inclined plate 96 and upward) to the inclined block 910. This normal force N can be decomposed into a horizontal component N. 水平 =N·cosθ, vertical component N 垂直 =N·sinθ, where the horizontal component N 水平The thrust generated by the hydraulic device 1 can be indirectly transmitted to the push plate 92 through the cooperation of the inclined block 910 with the corresponding two connecting rods 99 and the transmission plate 98. 垂直 The force is offset by the positional constraints of the two connecting rods 99 and the transmission plate 98, so this component force will not affect the movement of the push plate 92.
[0035] When hydraulic equipment 1 is running, it pushes and jacks pipes 3, 4, and subsequent pipes to be laid via push plate 92. At this time, due to the horizontal component force F on hydraulic equipment 1, 推初 =Ncosθ 初 (θ) 初 (where the inclination angle of the inclined plate 96 is the angle of inclination), and the F of the push plate 92 is... 初阻 Balance (i.e., F) 推初 =F 初阻 Therefore, at this time, the hydraulic equipment 1 and the push plate 92 can move synchronously. If the resistance of the communication pipeline increases by F... 新阻 >F 初阻 That is, the push plate 92 pushes the communication pipe forward and moves to the right, increasing the resistance (such as...). Figure 1 (As shown in the direction), at this time, the reverse resistance applied by the communication pipe to the push plate 92 will reduce the moving speed of the push plate 92. Meanwhile, because the hydraulic device 1 continues to move the drive plate on it to the right, the push plate 92 will move to the left relative to the drive plate (as shown in the direction). Figure 14 direction shown).
[0036] When the push plate 92 moves to the left relative to the hydraulic device 1, the push plate 92 will drive multiple transmission plates 98, multiple connecting rods 99, multiple inclined blocks 910, and multiple rack rods 913 on it to move to the left together. At this time, the rack rod 913 is subjected to force on the left side, and the driving force applied to the corresponding parallel shaft gear 912 can drive the corresponding rotating shaft 95 to drive the corresponding inclined plate 96 counterclockwise, so that the inclination angle of the inclined surface at the left end of the inclined plate 96 gradually increases (from cosθ). 初 variable cosθ 新 >cosθ 初 At this point, the horizontal component of the normal force on hydraulic equipment 1, i.e., on inclined plate 96, becomes F. 推新 =Ncosθ 新 (Because of cosθ) 新 >cosθ 初 Therefore, F at this time 推新 The thrust will increase non-linearly. At this point, the thrust indirectly transmitted to the push plate 92 through the inclined plate 96 will also gradually increase. This increases the indirect thrust of the hydraulic equipment 1 on the push plate 92, thus increasing the pushing force of the push plate 92 on the pipeline, until F... 推新 =F 新阻At this point, the push plate 92 gradually returns to a constant speed from the deceleration state and moves synchronously with the hydraulic equipment 1 again.
[0037] And when the inclined block 910 and the corresponding two round rods 911 are subjected to force, they move to the left (e.g. Figure 16 (In the direction shown) When the inclined plate 96 is driven by the force to rotate the corresponding two limiting plates 97 counterclockwise, the driving force applied by the two limiting plates 97 to the corresponding round rod 911 through their upper limit opening will make the inclined block 910 always in contact with the inclined surface of the corresponding inclined plate 96. This can ensure the stability of the thrust transmitted by the inclined plate 96 to the push plate 92 through the corresponding inclined block 910, the two connecting rods 99, and the transmission plate 98 during this stage.
[0038] Simultaneously, if the jacking resistance of the communication pipe decreases, the reverse resistance exerted by the communication pipe on the push plate 92 decreases (i.e., F). 新阻 <F 初阻 At this time, the horizontal component of the force indirectly transmitted from the inclined plate 96 to the push plate 92 does not have time to change (the thrust of the hydraulic device 1 is constant, and the response of the mechanical structure has a certain time process), therefore F 合 =F 初阻 -F 新阻 >0. At this time, according to Newton's second law F=ma (where F is the net force on the object, m is the mass of the object, and a is the acceleration of the object), since the net force to the right on the push plate 92 is greater than 0, the push plate 92 will generate a rightward acceleration. That is, the push plate 92 will move to the right relative to the hydraulic device 1 due to inertia (e.g., Figure 14 direction shown).
[0039] When the push plate 92 moves to the right relative to the hydraulic device 1, it will drive multiple transmission plates 98, multiple connecting rods 99, multiple inclined blocks 910, and multiple rack rods 913 on it to move to the right. At this time, the rack rods 913 are forced to the right, and the driving force applied to the corresponding parallel shaft gears 912 can drive the corresponding rotating shafts 95 to rotate the corresponding inclined plates 96 clockwise, so that the inclination angle of the right end of the inclined plate 96 gradually flattens (from cosθ). 初 variable cosθ 新 <cosθ 初 At this point, the horizontal component of the normal force on the inclined plate 96 becomes F. 推新 =Ncosθ 新 (Because of cosθ) 新 <cosθ 初 Therefore, F at this time 推新 The thrust will decrease non-linearly, and the thrust indirectly transmitted to the push plate 92 through the inclined plate 96 will also gradually decrease. This allows for a timely and adaptive reduction of the push plate 92's thrust on the communication pipe as the jacking resistance decreases, until F... 推新 =F新阻 At this point, the push plate 92 gradually returns to a constant speed from the accelerated state and moves synchronously with the hydraulic equipment 1 again.
[0040] Reference Figures 12-18 The adjustment component includes a motor 914 fixedly installed on the hydraulic equipment 1. A lead screw 915 is fixedly installed on the drive end of the motor 914, and one end of the lead screw 915 is rotatably installed on the inner wall of the circular roller 91. Two push plates 916 are installed on the lead screw 915 through two ball nuts, and both push plates 916 are slidably installed on the circular roller 91.
[0041] Before laying the communication pipeline, the jacking thrust of the device can be adjusted according to requirements (such as foundation resistance, pipeline parameters, etc.). If it is necessary to increase the intermittent laying thrust of the hydraulic equipment 1, the motor 914 can be started in the forward direction. At this time, the operation of the motor 914, through the cooperation of the lead screw 915 and two ball nuts, drives the two push plates 916 to move to the left (e.g., ...). Figure 18 (As shown in the direction) When the left end of the right push plate 916 contacts the side wall of the push plate 92, the thrust applied by the right push plate 916 to the push plate 92 can drive the push plate 92 to move to the left. As the push plate 92 moves to the left and gradually approaches the drive disc on the hydraulic device 1, according to the above operating principle, the inclined plate 96 will gradually rotate counterclockwise, gradually increasing the thrust indirectly transmitted by the hydraulic device 1 to the push plate 92 through the drive disc and multiple inclined plates 96, that is, increasing the thrust of the push plate 92 on the communication pipe, thus achieving... The effect of the device on the jacking thrust of the communication pipeline is increased according to the required adaptability; otherwise, the motor 914 needs to be driven in reverse. (In order to ensure that the push plate 92 can cooperate with the adjustment component 9 in a timely manner to adjust the thrust of the communication pipeline according to the change of the movement resistance of the communication pipeline during the subsequent jacking process, after the initial position of the push plate 92 is adjusted according to the required requirements, the two push plates 916 are driven to move and reset by the reverse motor 914 to prevent the two push plates 916 from obstructing the subsequent movement of the push plate 92.)
[0042] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
[0043] In this invention, when the device is needed to lay communication pipelines, the accuracy of the connection between pipeline 3 and pipeline 4, as well as the accuracy of the connection between pipeline 4 and subsequent pipelines to be laid, can be improved by the cooperation of the limiting component 6 and the correction component 8. This can help improve the laying effect of the device on communication pipelines.
[0044] Meanwhile, during the process of jacking the communication pipeline, the jacking force of the push plate 92 on the communication pipeline can be adaptively adjusted according to the pipeline jacking resistance, which can help to further improve the laying effect of the communication pipeline. Furthermore, through the adjustment component, the jacking force of the push plate 92 on the communication pipeline can be adaptively adjusted as needed when laying the communication pipeline, which can help to improve the applicability of the device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
