Description

Technical Field

[0001] This application belongs to the field of pipeline laying technology, and more specifically, relates to an automated support device for pipeline laying. Background Technology

[0002] Miscellaneous fill and silty soil are typical complex and weak geological formations, characterized by loose soil, low bearing capacity, and significant uneven settlement. When laying pipelines under such geological conditions, the sidewalls of trenches or foundation pits are prone to collapse and deformation. Therefore, temporary support devices must be used to ensure construction safety and quality.

[0003] Currently, common trench support devices often employ two symmetrically arranged support plates connected by cross braces or hydraulic rods to push the support plates apart to conform to the trench sidewalls. However, when applied to miscellaneous fill and silty soil, the highly uneven soil texture can cause the support plates to tilt during the spreading process due to excessive soil pressure on one side. This can lead to severe twisting and jamming in the connection structure between the spreading drive and the support plate. This jamming can prevent the hydraulic rods and other drive components from extending or retracting properly, or even cause the mechanism to seize up, directly affecting the reliability of the support and the construction progress.

[0004] Furthermore, the existing support devices typically have their expansion drive components fixedly installed in the middle of the support plate or at a certain height, making them impossible to adjust along the height. After the support plate is attached to the side wall, the expansion drive components and their associated structures occupy a large amount of space inside the support plate, resulting in the bottom area being unusable. This makes it inconvenient for construction workers to operate during pipeline laying, and may even require the removal of part of the support structure before subsequent work can proceed, posing safety hazards.

[0005] Therefore, there is an urgent need for a support device that can adapt to uneven lateral pressure and flexibly adjust the support space to solve the problems of easy jamming and poor space adjustment ability of existing technologies under the conditions of miscellaneous fill and silty soil. Summary of the Invention

A lifting drive assembly is installed on the support main plate and connected to the spreading drive component, used to drive the spreading drive component to lift and lower along the height direction of the support main plate. The expansion drive component rotates relative to each other to adapt to the tilt angle of the support body plate, and the lifting drive component drives the expansion drive component to lift and lower to adjust the support height of the support body plate, so that the two support body plates are expanded to avoid jamming and to reserve space for the bottom pipeline laying.

A pressure spring is sleeved on the buffer rod and abuts against the buffer slider; The cross rods are rotatably connected at their middle parts, and their two ends are rotatably connected to the buffer sliders on the inner slider and the outer slider, respectively.

[0014] In one possible implementation, the inner slider has a plurality of pressure switches arranged along its height direction installed inside it.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] Please see Figures 1 to 9 The automated pipeline laying support device provided in this application will now be described. An automated pipeline laying support device includes two support main plates 1, which are arranged mirror-imagely within a trench during use, respectively supporting the left and right sidewalls of the trench. The two support main plates 1 are connected by a spacing adjustment component, which is used to drive the two support main plates 1 closer together (retract) or further apart (spread out).

[0026] The spacing adjustment assembly includes at least one spreading drive component. Both ends of the spreading drive component are movably connected to two support body plates 1, and the spreading drive component is rotatable relative to the support body plates 1. That is, the ends of the spreading drive component are not rigidly fixed, but are connected to the support body plates 1 via hinges or rotating joints. Thus, when uneven lateral pressure from the fill or silty soil causes one of the support body plates 1 to tilt, the spreading drive component can automatically adjust its own axial direction, always applying force along the line connecting the two connection points, thereby avoiding twisting and ensuring smooth spreading or contraction.

[0027] The device also includes a lifting drive assembly, which is mounted on the support main plate 1 and connected to the spreading drive component. The lifting drive assembly drives the spreading drive component to move up and down along the height of the support main plate 1. When the device is first lowered to the bottom of the trench, the lifting drive assembly positions the spreading drive component at the bottom area of ​​the support main plate 1. At this point, the spreading drive component pushes the two sides of the support main plate 1 outwards with a lower support point, facilitating stable insertion of the device into the trench bottom. After the support main plate 1 is attached to and locked against the trench sidewalls, the lifting drive assembly then drives the spreading drive component to rise to the top area of ​​the support main plate 1, thus leaving a continuous, unobstructed space below the bottom of the support main plate 1 for construction personnel to lay pipelines.

[0028] The operating steps of this embodiment are as follows: First, suspend the two support main plates 1 above the trench and slowly lower them to the bottom of the trench. At this time, the lifting drive assembly keeps the spreading drive component in a low position. Second, activate the spreading drive component to gradually spread the two support main plates 1 to both sides until the outer side of the support main plates 1 contacts and presses against the trench sidewall. During this process, if the sidewall is uneven and causes one side of the support main plate 1 to tilt, the spreading drive component will automatically rotate to adapt and avoid jamming. Third, after the support main plates 1 are stably supported, activate the lifting drive assembly to lift the spreading drive component upward along the support main plates 1, freeing up the bottom area. Fourth, carry out pipeline laying operations in the freed-up bottom space. Fifth, after the laying is completed, the lifting drive assembly drives the spreading drive component back to its original position, the spreading drive component retracts, causing the support main plates 1 to detach from the sidewall, and finally the device is lifted out of the trench.

[0029] By leveraging the movable connection and adaptive rotation between the expansion drive component and the support main plate, the problem of the drive component easily jamming under uneven lateral pressure is solved. The lifting drive assembly moves the expansion drive component up and down, achieving a working mode of bottom expansion and top clearance, ensuring initial insertion stability and providing convenient space for pipeline laying. The entire solution improves the reliability and construction efficiency of support under complex geological conditions.

[0030] Please see Figure 1 , Figure 2 and Figure 6 As a specific embodiment of the automated pipeline laying support device provided in this application, the spreading drive component adopts a linear actuator, which can be any one of a hydraulic rod 7, an electric push rod, or a cylinder. In order to drive the linear actuator to move up and down along the support body plate 1, this embodiment is provided with a lifting drive assembly, which mainly consists of an adjusting screw 4, a connecting frame 5, and a drive source.

[0031] A motor plate 2 is fixed to one side of the support main plate 1 for mounting the drive source; a base block 17 is fixed at the corresponding position on the lower part of the support main plate 1. The drive source is preferably a servo motor 3, which is mounted on the top surface of the motor plate 2. Its output shaft passes vertically downward through the motor plate 2 and is fixed to the upper end of the adjusting screw 4 via a coupling or directly. The adjusting screw 4 is arranged vertically, and its lower end is rotatably connected to the base block 17 via a bearing. In this way, the adjusting screw 4 can rotate freely under the drive of the servo motor 3, while obtaining two support points at the top and bottom to ensure smooth rotation.

[0032] The connecting frame 5 is an intermediate component connecting the linear actuator and the adjusting screw 4. The connecting frame 5 has a threaded groove 18 inside, through which the adjusting screw 4 passes and forms a threaded engagement. Both sides of the connecting frame 5 also require sliding guides on the support body plate 1. The cylinder or piston rod end of the linear actuator is fixedly connected to the connecting frame 5.

[0033] When the servo motor 3 is powered on and rotates, the adjusting screw 4 rotates accordingly. Since the connecting frame 5 is restricted by the guide structure and cannot rotate, it can only move along the axial direction of the adjusting screw 4, thereby driving the linear actuator to rise or fall. When the device is first lowered to the bottom of the trench, the linear actuator is located at the lower part of the support body plate 1, using its lower thrust point to push the two support body plates 1 apart to the sides, which facilitates stable insertion into the bottom of the trench. When it is necessary to lay pipelines, the servo motor 3 reverses, and the linear actuator rises to the upper part of the support body plate 1, naturally creating an unobstructed working space at the bottom. This structure achieves flexible adjustment of the support height and precise and reliable movement.

[0034] Please see Figure 2 and Figure 6 As a specific embodiment of the automated pipeline laying support device provided in this application, the lower end of the adjusting screw 4 needs to be supported to rotate stably. In this embodiment, a base block 17 is specifically provided, which is fixedly connected to the lower side of the support body plate 1, and its position corresponds vertically to the upper motor plate 2. The base block 17 may have a countersunk hole or a bearing installed inside, and the lower end of the adjusting screw 4 is inserted into the countersunk hole or the bearing's inner hole to form a rotating connection. With the support of the base block 17, the adjusting screw 4 will not bend or deform when bearing the weight of the connecting frame 5 and the linear actuator, ensuring the straightness of the lifting movement and the reliability of long-term use. At the same time, the presence of the base block 17 also provides a solid lower support point for the entire lifting drive assembly, making the rotation of the adjusting screw 4 more stable and reducing vibration and noise.

[0035] Please see Figure 6 , Figure 7 and Figure 9As a specific embodiment of the automated pipeline laying support device provided in this application, the two ends of the spreading drive are respectively connected to two support body plates 1 through a set of rotating connection components. Each set of rotating connection components includes a rotating body 22, a rotating block 8, and a locking component for locking.

[0036] Specifically, an auxiliary plate 21 is fixed to the inner side of the main support plate 1, and a rotating body 22 is welded or bolted to the auxiliary plate 21. The rotating body 22 is shaped like a U-shaped bracket, with coaxial through holes on its two side walls. A rotating block 8 is installed in the U-shaped groove of the rotating body 22, and a transverse through mounting hole is also provided on the rotating block 8.

[0037] To form a rotatable connection, a rotating bolt 19 is used to pass through the through hole on one side wall of the rotating body 22, the mounting hole of the rotating block 8, and then through the through hole on the other side wall of the rotating body 22. Second nuts 33 are screwed onto both ends of the rotating bolt 19. By adjusting the tightness of the second nuts 33, the rotating block 8 can be ensured to rotate flexibly, and can also be completely locked when needed. When the second nuts 33 are loose, the rotating block 8 can rotate freely around the axis of the rotating bolt 19, thereby causing the expansion drive component fixed to it to adapt to the tilt angle of the support body plate 1. When the expansion drive component has extended or retracted to its position and the support body plate 1 has adhered to the trench sidewall, the second nuts 33 can be further tightened, clamping the rotating block 8 between the two side walls of the rotating body 22, thereby locking the angle and preventing angle changes due to vibration during subsequent construction.

[0038] For other parts of the device that need to be detachable and fixed, the plug bolts 11 can be used in conjunction with the first nut 32 for locking. The principle is similar to that described above, and will not be described in detail here.

[0039] Please see Figure 1 , Figure 2 , Figure 4 and Figure 7 As a specific embodiment of the automated pipeline laying support device provided in this application, the guide structure includes a guide rail 6 and a movable slider 9. The guide rail 6 is a long strip-shaped metal component, which is fixedly connected to the inner side of the support body plate 1 (i.e., the side facing the other support body plate) and extends vertically along the height direction of the support body plate 1. A through guide groove 20 is opened on the side of the guide rail 6 facing the center of the support body plate 1. The cross-section of the guide groove 20 is usually T-shaped or rectangular.

[0040] The movable slider 9 is fixedly connected to the side of the connecting frame 5. Specifically, the two sides of the connecting frame 5 extend outward to form protrusions, which are the movable sliders 9. The movable slider 9 is inserted into the opening of the guide groove 20 and can slide freely up and down along the guide groove 20. When the adjusting screw 4 drives the connecting frame 5 to rise and fall, the movable slider 9 slides in the guide groove 20. The side wall of the guide groove 20 applies a horizontal constraint to the movable slider 9, so that the connecting frame 5 can only move in the vertical direction and will not swing back and forth or twist left and right, thereby ensuring the straightness of the linear actuator's lifting trajectory.

[0041] In addition, to provide another fixed hinge point for the expansion drive component, a fixing block 10 is also fixed inside the guide rail 6. For example... Figure 4 and Figure 7 As shown, the fixing block 10 is inserted into the threaded hole of the guide rail 6 by means of a plug bolt 11 passing through the side wall of the guide rail 6, or the fixing block 10 is clamped in a predetermined position within the guide rail 6 by means of a plug bolt 11 together with a first nut 32. In this way, the fixing block 10 remains stationary relative to the support body plate 1. An auxiliary plate 21 is provided on both the fixing block 10 and the movable slider 9, and the auxiliary plate 21 is used to connect the rotating body 22. Thus, the rotating connection assembly connected to the fixing block 10 remains fixed, while the rotating connection assembly connected to the movable slider 9 can rise and fall with the connecting frame 5, realizing a movement mode in which one end of the supporting drive component is fixed and the other end is raised and lowered.

[0042] In environments with mixed fill and silty soil, trench sidewalls are often soft and uneven, making them prone to impact when the support panels are deployed. To absorb this impact and achieve adaptive fit, this embodiment incorporates an adaptive buffer abutment component. Please refer to... Figure 3 , Figure 4 and Figure 8 .

[0043] The adaptive buffer abutment assembly includes an inner slider 23, an outer slider 24, and a buffer unit located between them. The inner slider 23 is fixed to the outer side of the support body plate 1 (i.e., the side facing the trench sidewall). The outer slider 24 is sleeve-shaped and slides around the outer side of the inner slider 23, meaning that the outer slider 24 can slide relative to the inner slider 23 in a direction perpendicular to the support body plate 1. The outer side of the outer slider 24 directly abuts against the inner wall of the trench and is the final component of the device that comes into contact with the soil.

[0044] The buffer unit connects the inner slider 23 and the outer slider 24. Its function is to absorb energy and reduce impact when the outer slider 24 is subjected to sidewall pressure. When the drive component pushes the support plate 1 outward, the outer slider 24 first contacts the trench sidewall. After receiving the reaction force, it slides towards the inner slider 23. The buffer unit stores or dissipates this energy through elastic deformation or damping, preventing rigid collisions from damaging the device or causing the sidewall to collapse. At the same time, the buffer unit can also provide a certain preload between the outer slider 24 and the inner slider 23, keeping the outer slider 24 in the extended position in a free state.

[0045] Please see Figure 8 As a specific embodiment of the automated pipeline laying support device provided in this application, the buffer unit includes a buffer frame 26, a buffer rod 27, a buffer slider 29, a pressure spring 28, and a cross support rod 30. A buffer frame 26 is fixed to the inner side of each of the inner slider 23 and the outer slider 24, resulting in a total of two buffer frames 26. At least one buffer rod 27 is fixed to each buffer frame 26 in the horizontal direction (sliding direction), with the end of the buffer rod 27 being a free end. Two buffer sliders 29 are slidably sleeved on each buffer rod 27, arranged in a mirror image, one near the inner side and the other near the outer side. The pressure spring 28 is sleeved on the buffer rod 27, with one end contacting the buffer frame 26 and the other end contacting the inner or outer buffer slider 29.

[0046] There are two cross braces 30, which are hinged together in the middle by a rotating column 31 to form an X shape. The four ends of the X shape are rotatably connected to the two buffer sliders 29 on the inner slider 23 and the two buffer sliders 29 on the outer slider 24, respectively.

[0047] When the outer slider 24 moves inward under pressure, the angle between the two intersecting rods 30 increases, thereby pushing the buffer slider 29 to slide along the buffer rod 27 to both sides, compressing the pressure spring 28. In this way, the external impact energy is converted into the elastic potential energy of the pressure spring 28, achieving buffering. When the external pressure disappears, the pressure spring 28 pushes the buffer slider 29 to reset, the angle between the intersecting rods 30 decreases, and the outer slider 24 is pushed back to its original position.

[0048] This scissor-type linkage buffer structure has advantages such as large buffer stroke, uniform force distribution, and compact structure, making it particularly suitable for mixed fill and silty soil environments that require a large buffer margin. At the same time, the combination of the cross strut 30 and the pressure spring 28 can also provide a certain self-adaptive centering force, ensuring that the outer slider 24 can always closely fit the irregular sidewall.

[0049] Please see Figure 8As a specific embodiment of the automated pipeline laying support device provided in this application, a plurality of pressure switches 25 are installed inside the inner slider 23 (or on its outer surface along its sliding direction). These pressure switches 25 are arranged along the height direction (i.e., the sliding direction) of the inner slider 23. In a preferred embodiment, there are four pressure switches 25, each corresponding to a different sliding stroke position of the outer slider 24. The output terminal of each pressure switch 25 is electrically connected to the control circuit of the opening drive (e.g., hydraulic rod 7) via a wire.

[0050] When the expansion drive pushes the support plate 1 outward, the outer slider 24 gradually contacts the trench sidewall and begins to slide towards the inner slider 23 under counter-pressure. As the sliding distance increases, the inner wall of the outer slider 24 will sequentially touch and trigger pressure switches 25 at different positions. When the outer slider 24 slides to the very end (i.e., all four pressure switches 25 are triggered), the control circuit determines that the outer slider 24 has reached the ideal contact pressure with the trench sidewall (at this time, the track body 15 is also tightly pressed against the sidewall), and then automatically cuts off the power source of the expansion drive, stopping its extension. In this way, the device can automatically adjust the expansion degree according to the actual trench width to achieve adaptive contact. In addition, it can also be preset to stop when only two or three pressure switches are triggered, depending on the actual soil conditions, to adjust the preload. This graded control method improves the intelligence and adaptability of the device.

[0051] Please see Figure 3 , Figure 4 and Figure 5 As a specific embodiment of the automated pipeline laying support device provided in this application, during the process of lowering the entire device into the trench, there is a large sliding friction between the outer surface of the support main plate and the trench sidewall, especially in deeper trenches. This friction increases the difficulty of lowering and may damage the sidewall. To reduce friction, an auxiliary moving component is added.

[0052] The auxiliary moving assembly includes a moving frame 12, multiple moving rollers 13, and a ring-shaped track body 15. The moving frame 12 is fixedly connected to the outside of the outer slider 24, i.e., the side facing the trench sidewall. Typically, two moving frames 12 are symmetrically arranged along the longitudinal centerline of the outer slider 24, and the two moving frames 12 are connected to each other by an internal abutment plate 14 to enhance overall rigidity. Moving rollers 13 are rotatably mounted at the upper and lower ends of each moving frame 12, for example, supported by bearings, so that each moving frame 12 has at least two moving rollers 13, one upper and one lower.

[0053] The annular track body 15 is fitted around the upper and lower movable rollers 13, and forms a track surface that can roll continuously by relying on the support and tension of the movable rollers 13. Track grooves 16 are formed on the outer surface of the track body 15 to increase the friction with the sidewalls of the grooves and prevent slippage; the material of the track body 15 is preferably synthetic rubber, which is both wear-resistant and has a certain degree of elasticity.

[0054] When the device descends vertically under the traction of the slings, the track body 15 first contacts the sidewall of the trench. Under the action of gravity and friction, the track body 15 drives the moving rollers 13 to rotate, thereby converting the original sliding friction into rolling friction and significantly reducing the descent resistance. Simultaneously, because the track body 15 moves in a cyclical motion, it does not leave deep scratches on the sidewalls like a sliding plate, thus protecting the soft fill and silty soil sidewalls. During the device's ascent and retraction, the auxiliary moving components also reduce resistance. It should be noted that the number of moving rollers 13 can be set in multiple groups depending on the device height; for example, moving rollers 13 can be added in the middle of the moving frame 12 to provide more even support.

[0055] Working principle: The main support plate 1 can be suspended from the top of the trench using a crane, and the main support plate 1 can be gradually lowered.

[0056] Then, the hydraulic rod 7 is activated to push the support plate 1 to move until it abuts against the inner wall of the trench. During this process, the bottom hydraulic rod 7 remains at the bottom of the support plate 1, ensuring that the thrust on the support plate 1 is more even, until the pointed end of the support plate 1 is inserted into the bottom of the trench.

[0057] Next, the servo motor 3 is started to drive the adjusting screw 4 to rotate, so that the connecting frame 5 slides on the inner wall of the guide rail 6, and simultaneously drives the hydraulic rod 7 to rise, thereby reserving space at the bottom for the buried pipeline.

[0058] During the extension of the hydraulic rod 7, the hydraulic rod 7 can rotate inside the rotating body 22, so that when the support body plate 1 is tilted on one side, the hydraulic rod 7 will not be subjected to force, thus ensuring the normal extension and retraction of the hydraulic rod 7.

[0059] The outer slider 24 can slide outside the inner slider 23. During the unfolding of the support main plate 1, the outer slider 24 slides on the inner slider 23 and drives the buffer slider 29 to cooperate with the cross support rod 30, so that the buffer slider 29 slides outside the buffer rod 27. At the same time, the pressure spring 28 is compressed, which plays an auxiliary buffering role.

[0060] As the outer slider 24 slides outside the inner slider 23, it gradually comes into contact with the pressure switch 25. The hydraulic rod 7 stops extending once all four pressure switches 25 are activated. At this point, the track body 15 of the support plate 1 is precisely abutting against the inner wall of the trench for support, thus achieving adaptive adjustment of the support plate 1.

[0061] During the movement of the support body plate 1, the track body 15 first abuts against the inner wall of the trench, and the track groove 16 increases the friction between the track body 15 and the inner wall of the trench. This allows the track body 15 to move externally to the moving roller 13 during the descent of the support body plate 1, thereby reducing the friction between the support body plate 1 and the trench during descent and facilitating the convenient descent of the support body plate 1 during the support process.

[0062] The above are merely preferred embodiments of this application and are not intended to limit this application.
