Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pipeline laying, in particular to a communication pipeline automatic laying device. BACKGROUND

[0002] In order to reduce the damage of cable and optical cable from the environment, and to provide a stable channel for the laying, maintenance and expansion of cable, a communication pipeline is usually laid in advance before the laying of cable and optical cable. However, due to the traditional excavation laying method, it is difficult to adapt to complex scenes such as crossing rivers and soft soil layers, because it easily affects traffic, damages existing pipelines and has low efficiency. Therefore, the non-excavation automatic device gradually becomes an inevitable choice to replace the traditional method. For example, the slurry balance pipe jacking machine can effectively solve a series of problems in the traditional open-cut method of laying pipeline, including interference with traffic, damage to existing pipelines, and high subsequent repair costs. At the same time, it can also significantly improve the efficiency and quality of automatic laying of communication pipeline, so the device has been widely used in the field of automatic laying of communication pipeline.

[0003] Before the existing slurry balance pipe jacking machine lays the communication pipeline automatically, it usually pre-inspects the existing hydraulic system for the jacking thrust of the pipeline according to factors such as stratum base resistance, pipeline parameters, and pipeline jacking distance length. However, during the jacking of the pipeline, due to factors such as stratum changes and grouting and lubrication mismatch, it is easy to cause "jacking stagnation due to insufficient thrust" or "damage to equipment / pipeline due to excessive thrust" during the jacking of the communication pipeline, which reduces the effect of the device on the automatic laying of the communication pipeline. Therefore, we propose a communication pipeline automatic laying device to solve the above problems. SUMMARY

[0004] The purpose of the present application is to solve the problems raised in the background art by providing a communication pipeline automatic laying device.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme:

[0006] A communication pipeline automatic laying device, comprising a hydraulic device, a tunneling machine, a pipeline one, a pipeline two, and a fixed plate, wherein the hydraulic device is provided with a deviation correction assembly for improving the accuracy of the communication pipeline butt joint, and the hydraulic device is provided with an adjusting assembly for adaptively adjusting the jacking thrust of the communication pipeline.

[0007] The deviation correction assembly comprises a guide rail fixedly installed on the hydraulic device, and the guide rail is provided with an adjusting mechanism.

[0008] 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.

[0009] Compared with existing technologies, the advantages of this invention are:

[0010] 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.

[0011] 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.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0036] Reference Figures 1-18 A communication pipeline automatic laying device, comprising a hydraulic device 1, a heading machine 2, a pipeline one 3, a pipeline two 4, a fixed plate 5, the hydraulic device 1 is provided with a deviation rectification assembly 8, which is used to improve the precision of the communication pipeline butt joint, and the hydraulic device 1 is provided with an adjusting assembly 9, which is used to adaptively adjust the communication pipeline jacking thrust.

[0037] When the device needs to be used to lay the communication pipeline, a working well and a receiving well need to be built at the starting point and the ending point of construction respectively, and then the existing hoisting equipment is used to hoist and fixedly install the hydraulic device 1 and the guide rail 7 in the preset position in the working well, and then the existing hoisting equipment is used to hoist the heading machine 2 to the guide rail 7, and then the heading machine 2 is pushed along the preset axis by the cooperation of the hydraulic device 1 and the heading machine 2, and after the heading machine head 2 is jacked into position, the existing hoisting equipment is used to hoist and place the pipeline one 3 on the guide rail 7, and in order to ensure the butt joint effect of the first jacking pipe body and the heading machine 2, the laser positioning and calibration of the axis of the first pipe body and the heading machine 2 is usually carried out at present, so as to ensure the butt joint effect of the two;

[0038] After the pipe 3 and the tunneling machine 2 are connected, the hydraulic equipment 1 is continuously pushed, so that the pipe 3 is gradually pushed into the cut soil space, and the tunneling machine 2 is continuously cut along the preset axis, and then the pipe is continuously connected, so that the communication pipe is continuously laid in the soil, until the tunneling machine 2 reaches the receiving well, and the automatic laying of the first communication pipe is completed (the working principle is similar to that of the existing slurry balance pipe jacking machine).

[0039] With reference to Figures 1-3 The fixing plate 5 is provided with a limiting assembly 6, the limiting assembly 6 comprises a support plate 61 fixedly installed in an arc shape on the fixing plate 5, threaded rods one 62 are rotatably installed on the support plate 61, sliding frames are threadedly installed on the threaded rods one 62, and limiting rollers one 63 are rotatably installed on the sliding frames.

[0040] After the hydraulic equipment 1 and the guide rail 7 are fixedly installed at the preset position, the fixing plate 5 can be fixedly installed on the side wall of the working well opposite to the hydraulic equipment 1 through a plurality of bolts on the fixing plate 5, so that the position of the mobile communication pipe can be limited through the limiting assembly 6, and the laying effect of the device on the communication pipe is improved.

[0041] After the pipe 3 and the tunneling machine 2 are connected, and before the pipe 3 is continuously pushed into the cut soil space, the position of the limiting rollers one 63 can be adjusted according to the outer diameter of the pipe 3, if the pipe 3 has a small diameter, the threaded rods one 62 are sequentially and forwardly rotated to drive the sliding frames to drive the limiting rollers one 63 to approach each other until the limiting rollers one 63 are attached to the outer wall of the pipe 3 (the pipe sections of the pipe 3, the pipe 4 and the subsequent inclined communication pipe have the same size and shape), and the limiting rollers one 63 apply a certain extrusion force to the pipe 3 (the extrusion force applied by the limiting rollers one 63 to the pipe 3 is small, so that the pipe 3 and the subsequent pipe 4 and the to-be-laid pipe are limited in position, and the extrusion force applied by the limiting rollers one 63 to the pipe 3 is not too large, so that the frictional resistance of the pipe 3, the pipe 4 and the like when being pushed forward is reduced, and the laying efficiency of the communication pipe is improved).

[0042] The existing slurry balance pipe jacking machine, in the process of automatic laying of the pipeline, on the one hand, due to uneven settlement or lateral pressure of underground stratum (such as soft soil, sand layer), the communication pipeline is easy to deviate due to uneven thrust and different stratum friction during jacking, on the other hand, the communication pipeline needs to maintain straightness and sealing to protect the cable, if the pipeline is inclined, it may cause interface leakage, cable extrusion damage, and the cable threading difficulty will be greatly increased during subsequent maintenance, therefore, by limiting the movement of the pipeline 3 and the subsequent communication pipeline (including the pipeline 2 4) through the plurality of limiting rollers 63, the laying effect of the pipeline can be improved, at the same time, by limiting the movement of the pipeline 3 and the subsequent pipeline, the additional extrusion or loosening of the surrounding soil by the communication pipeline during the laying of the communication pipeline can be effectively reduced, which can to some extent start the effect of protecting the surrounding buildings, pipelines and the like, in addition, by limiting the movement of the pipeline 3, the accuracy of the connection between the pipeline 3 and the pipeline 2 4 and the accuracy of the connection between the pipeline 2 4 and the subsequent pipeline can be improved, and the sealing property of the connection between the pipelines (if the sealing effect between the pipelines is poor, impurities such as mud are easy to enter the pipeline from the joint gap between the pipelines after the pipeline is laid, which can corrode and damage the cables laid in the pipeline).

[0043] Reference Figures 1-11 The deviation correction assembly 8 comprises guide rails 7 fixedly installed on the hydraulic device 1 (the guide rails 7 can limit the height of the communication pipeline, ensure that the communication pipeline is at the same height, and improve the accuracy of the connection between the pipelines to some extent), and an adjusting mechanism installed on the guide rails 7.

[0044] The adjusting mechanism comprises a placing box 83 fixedly installed on the guide rails 7, two threaded rods 85 rotatably installed on the placing box 83, two moving pieces 86 threadedly installed on the two threaded rods 85, the two moving pieces 86 slidably installed on the placing box 83, two adjusting plates 88 fixedly installed on the two moving pieces 86, and a plurality of limiting rollers 89 rotatably installed on the adjusting plates 88 in a linear and uniform manner. A pushing part is installed on the hydraulic device 1, and a driving part is installed on the guide rails 7.

[0045] The pushing part comprises a circular ring 81 fixedly installed on the hydraulic device 1, two pushing rods 82 fixedly installed on the circular ring 81, two spring telescopic rods 810 fixedly installed on the two pushing rods 82, and a driving block 811 fixedly installed between the two spring telescopic rods 810.

[0046] The driving component comprises two fixed boxes 84 fixedly installed on the guide rail 7, two limiting frames 812 fixedly installed on the two fixed boxes 84, two sliding blocks 813 slidingly installed on the two limiting frames 812, two tooth conditions 814 fixedly installed on the two sliding blocks 813 and matched with the corresponding driving blocks 811, and two threaded rods two 85 fixedly installed with the rotating gears 87 matched with the corresponding tooth conditions 814.

[0047] The existing slurry balance pipe jacking machine mostly adjusts the position of the new pipe by manual mode after hoisting each section of communication pipe to the upper end of the track by using the existing hoisting equipment. However, the accuracy of the butt joint of the new pipe and the laid pipe is easily reduced due to the influence of human factors, the sealing effect between the two pipes after butt joint is reduced, and if there is a slight deviation in the butt joint, the interface stress is increased, which may cause pipe joint "misalignment" and even cannot continuously complete the subsequent butt joint, and the pipe laying effect and efficiency are reduced. In addition, if the laid communication pipe is made of concrete material, the butt joint of the two pipes is easily cracked due to uneven stress, and if the laid communication pipe is made of plastic (such as PE material), the pipe is easily deformed due to excessive jacking resistance, which reduces the service life of the laid communication pipe.

[0048] Therefore, when the pipe one 3 is butt jointed with the heading machine 2 and the hydraulic equipment 1 jacks the pipe one 3 into position, the pipe two 4 is hoisted to the guide rail 7, and the hydraulic equipment 1 is started first. At this time, the operation of the hydraulic equipment 1 first drives the two push rods 82, the plurality of spring telescopic rods 810 and the two driving blocks 811 to move to the right side (in the direction shown in combination with Figure 9 and Figure 10 the two driving blocks 811 are forced to move to the right side, the right end inclined surface of the two driving blocks 811 applies a pushing force to the left end inclined surface of the corresponding tooth condition 814, which drives the corresponding tooth condition 814 to move to the right side, and the two tooth conditions 814 are forced to move to the right side, which applies a driving force to the corresponding rotating gear 87, which drives the two rotating gears 87 to rotate, and the rotating directions of the two threaded rods two 85 are opposite (the two tooth conditions 814 are arranged above and below the corresponding rotating gear 87, which is to drive the two rotating gears 87 to rotate relatively when the two tooth conditions 814 are forced to move to the right side).

[0049] When the two threaded rods two 85 are forced to rotate relatively, the plurality of adjusting plates 88 and the limiting roller two 89 are driven to move close to each other by the two moving pieces 86. At this time, if the pipe two 4 is not located at the middle position of the guide rail 7 and is not aligned with the hydraulic equipment 1 and the pipe one 3, for example, the pipe two 4 is placed to the right side (for example, 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.

[0050] 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).

[0051] 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.

[0052] At the same time, the hydraulic device 1 and the push plate 92 continue to move to the right, and the push plate 92 is in contact with the left end of the pipeline two 4 (the right side of the push plate 92 is not in contact with the left end of the pipeline two 4 when the position of the pipeline two 4 is corrected through the deviation correction assembly 8), at this time, through the continuous operation of the hydraulic device 1, the push plate 92 can first push the pipeline two 4 to complete the butt joint with the pipeline one 3, and then the pipeline two 4 is pushed into place, and then the hydraulic device 1 is driven to reset. After the hydraulic device 1 and the push plate 92 move to reset, the above operation is repeated to correct the position of the remaining communication pipeline to be laid and automatically lay.

[0053] At the same time, the hydraulic device 1 drives the circular ring 81, the two push rods 82 and the two drive blocks 811 to move to the left side and reset (as shown in the direction of Figure 9 When the left end of the two drive blocks 811 is in contact with the right side of the inclined surface of the corresponding tooth condition 814, the push plate 92 can be pushed to the left side and reset (in combination with Figure 10 and Figure 11 directions shown in

[0054] When the two tooth conditions 814 are driven to move to the leftmost end of the corresponding limiting frame 812, the limiting frame 812 indirectly limits the movement of the corresponding tooth condition 814 through the corresponding sliding block 813, which can limit the position of the two tooth conditions 814. At this time, when the two drive blocks 811 continue to move to the left, they will continuously move upwards along the right end of the corresponding tooth condition 814 until the two drive blocks 811 move above the corresponding tooth condition 814. After that, through the continuous left movement of the drive block 811, the two drive blocks 811 can be driven to move downward and reset again under the elastic force of the corresponding two spring extension rods 810. In this way, the subsequent position correction of the pipeline to be laid can be facilitated through the cooperation of the two drive blocks 811 and the deviation correction assembly 8.

[0055] Referring to Figure 1 , Figures 12-18The adjusting assembly 9 comprises a round roller 91 fixedly installed on the hydraulic device 1, a position adjusting part is installed on the round roller 91, a pushing plate 92 is slidably installed on the round roller 91, a plurality of rod bodies 94 are fixedly installed on the hydraulic device 1, a rotating shaft 95 is rotatably installed through and between every two adjacent rod bodies 94, an inclined plate 96 is fixedly installed on the rotating shaft 95, a plurality of transmission plates 98 are fixedly installed on the pushing plate 92 in a ring shape and uniformly distributed, two connecting rods 99 (having a force-stretching function) are fixedly installed on the transmission plate 98, an inclined block 910 matched with the corresponding inclined plate 96 is fixedly installed between every two adjacent connecting rods 99, and a rotating mechanism is jointly installed between the rotating shafts 95.

[0056] The rotating mechanism comprises a rack rod 913 fixedly installed on the pushing plate 92 in a ring shape, a parallel shaft gear 912 matched with the corresponding rack rod 913 is fixedly installed on the rotating shaft 95, a plurality of cylinders 93 are fixedly installed on the pushing plate 92 in a ring shape and uniformly distributed, the rod bodies 94 are slidably installed through the corresponding cylinders 93, and a limiting part is jointly installed between the inclined plates 96.

[0057] The limiting part comprises a plurality of round rods 911, every two adjacent round rods 911 are fixedly installed on the corresponding inclined block 910, two limiting plates 97 are fixedly installed on the inclined plate 96, and a limiting opening matched with the corresponding round rod 911 is formed in the limiting plate 97.

[0058] The existing slurry balance pipe jacking machine usually determines the jacking thrust of the pipe by the existing hydraulic system according to the factors such as the stratum foundation resistance, the pipe parameter, the pipe jacking distance length and the like before the automatic laying and jacking of the communication pipe, but in the process of jacking the pipe, if the stratum changes from soft soil to hard stratum, the grouting lubrication is insufficient, the muck discharge is not smooth (for example, the mud pipe is blocked by large pieces of sundries, the pressure of the mud tank is increased to cause the resistance to increase) and the like, the jacking resistance of the pipe will increase, and if the stratum becomes soft or a cavity is encountered (for example, the pipe enters the silt layer), the grouting is excessive and the like, the jacking resistance of the pipe will decrease.

[0059] When the jacking resistance of the pipe increases, if the jacking resistance exceeds the set thrust of the existing jacking equipment, the pipe jacking will be stalled, and even the hydraulic system of the existing jacking equipment will leak, the pipe interface will crack due to uneven force and the like, and when the jacking resistance of the pipe decreases, the pipe is prone to "stall" due to inertia, the pipe axis is deviated (if the laid communication pipe is sensitive to the elevation deviation, the deviation may affect the cable laying), and the laying precision of the pipe as a whole is reduced.

[0060] 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".

[0061] 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 corresponding two connecting rods 99 and the transmission plate 98, so this component force will not affect the movement of the push plate 92.

[0062] 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 jacking 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).

[0063] 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.

[0064] And when the inclined block 910 and the corresponding two round rods 911 are subjected to force and move to the left (such as...) 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.

[0065] 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 force of the object, m is the mass of the object, a is the acceleration of the object), because the pushing plate 92 is subjected to a rightward combined force greater than 0, so the pushing plate 92 will generate a rightward acceleration at this time, that is, at this time the pushing plate 92 will move to the right side relative to the hydraulic device 1 due to inertia (as shown in the direction of Figure 14

[0066] When the pushing plate 92 moves to the right side relative to the hydraulic device 1, the pushing plate 92 will drive the plurality of transmission plates 98, the plurality of connecting rods 99, the plurality of inclined blocks 910 and the plurality of rack rods 913 together to move to the right side at this time, the driving force exerted on the corresponding parallel shaft gear 912 through the rack rod 913 right-moving under stress can drive the corresponding rotating shaft 95 to drive the corresponding inclined plate 96 to rotate clockwise, so that the inclination angle of the right end inclined surface of the inclined plate 96 gradually flattens (from cosθ 初 to cosθ 新 < cosθ 初 ), at this time the horizontal component of the normal force decomposed on the inclined plate 96 becomes F 推新 = Ncosθ 新 (because cosθ 新 < cosθ 初 ), therefore F 推新 will be nonlinearly reduced at this time, at this time the pushing force indirectly transmitted to the pushing plate 92 through the inclined plate 96 will also gradually decrease, so that the effect of the pushing plate 92 on the pipeline pushing force can be timely and adaptively reduced when the communication pipeline jacking resistance decreases, until F 推新 = F 新阻 at this time the pushing plate 92 gradually recovers from the acceleration state to the uniform speed, and synchronously moves with the hydraulic device 1 again.

[0067] Referring to Figures 12-18 , the positioning component includes a motor 914 fixedly installed on the hydraulic device 1, a lead screw 915 fixedly installed at the driving end of the motor 914, one end of the lead screw 915 rotatably installed on the inner wall of the circular roller 91, and two push plates 916 installed on the lead screw 915 through two ball nuts, and the two push plates 916 are both slidingly installed on the circular roller 91.

[0068] Before the device lays the communication pipeline, the jacking pushing force of the device on the communication pipeline can be adaptively adjusted according to the needs (such as the ground foundation resistance, the pipeline itself parameters, etc.), if it is necessary to increase the indirect laying pushing force of the hydraulic device 1 on the communication pipeline, the motor 914 can be started in a positive direction at this time, the operation of the motor 914 can drive the two push plates 916 to move to the left side (as shown in the direction of Figure 18 ​When the right pushing plate 916 is driven to move to the left, the pushing plate 92 gradually moves to the left and gradually approaches the driving disc on the hydraulic equipment 1, according to the above operation principle, the inclined plate 96 gradually rotates counterclockwise, gradually increasing the pushing force of the pushing plate 92 on the hydraulic equipment 1 through the driving disc and the plurality of inclined plates 96, that is, increasing the pushing force of the pushing plate 92 on the communication pipeline, realizing the effect of adaptively increasing the pushing force of the device on the communication pipeline laying, and vice versa. The motor 914 needs to be reversed to drive the two pushing plates 916 to move back to the original position to prevent the two pushing plates 916 from hindering the subsequent movement of the pushing plate 92.

[0069] Further, the above-mentioned fixed connection should be understood in a broad sense unless otherwise specified and limited, for example, it can be welding, gluing, or integrally formed with other conventional means familiar to those skilled in the art.

[0070] In the present application, when the device needs to lay the communication pipeline, the abutment accuracy between the pipeline one 3 and the pipeline two 4, and the abutment accuracy between the pipeline two 4 and the subsequent pipeline to be laid can be improved through the cooperation of the limiting assembly 6 and the deviation correcting assembly 8, which can help to improve the laying effect of the device on the communication pipeline.

[0071] Meanwhile, during the process of pushing the communication pipeline by the device, the pushing force of the pushing plate 92 on the communication pipeline can be adaptively adjusted according to the pipeline pushing resistance, which can help to further improve the laying effect of the device on the communication pipeline, and through the position adjusting component, the pushing force of the pushing plate 92 on the communication pipeline can be adaptively adjusted according to the needs during the device laying the communication pipeline, which can help to improve the application range of the device.

[0072] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change within the technical range disclosed by the present application according to the technical solution and inventive concept of the present application, which should be covered within the protection scope of the present application.
