Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, and more specifically to a pipeline sliding and positioning system for terrain with large elevation differences. Background Technology

[0002] In the construction of municipal heating pipelines, various situations arise depending on the terrain and topography of the project. For example, when heating pipelines are designed on hills with significant elevation differences, the terrain is often rugged, making it impossible for construction vehicles to operate normally. Transporting large-diameter heating pipelines to concrete supports becomes a major challenge. How to safely and efficiently transport pipelines to their installation location and place them in complex terrain or confined spaces where ground hoisting machinery cannot access has long been a concern for technical personnel in the field.

[0003] To address construction environments where hoisting equipment is restricted, existing technologies have proposed several solutions. For example, existing technologies include pipeline sliding devices. These devices typically include sliding tracks, sliding trolleys, traction components, and lifting components. The sliding trolley is slidably mounted on the sliding tracks. The traction component pulls the trolley, moving the pipeline to a preset position. Then, the lifting component raises the pipeline to a preset height, and finally, the pipeline is secured. This facilitates pipeline movement in confined spaces and offers excellent stability. This existing technology solution, by arranging sliding tracks on concrete supports and using the sliding trolley to move along the tracks for pipeline transportation, solves to some extent the construction difficulties where hoisting equipment cannot access the site.

[0004] However, the aforementioned existing technologies still have the following shortcomings: 1) Excessive requirements for the positioning accuracy of transport equipment: In existing technologies, the lifting components are usually fixed at a preset position next to the sliding track. The sliding trolley must precisely stop at the lifting component to complete the lifting and positioning of the pipeline. In terrain with large elevation differences, factors such as track laying errors and sliding trolley positioning errors are difficult to avoid. Requiring precise positioning of the sliding trolley is not only difficult to operate, but also inefficient. Once the positioning deviation exceeds the allowable range, repeated adjustments are required, seriously affecting the construction progress.

[0005] 2) The transportation and placement processes are mutually constrained, making continuous operation impossible: In existing technologies, the sliding trolley can only be removed after the pipeline is lifted and the next pipeline can be transported. This sequential operation mode causes the transportation and placement processes to wait for each other, making it difficult to improve construction efficiency. This is especially true in projects with a large number of pipelines, where the accumulated waiting time makes the efficiency bottleneck particularly prominent. Summary of the Invention

[0006] The purpose of this invention is to solve the technical problem in the prior art that pipelines need to be precisely aligned after transportation to the site before they can be put into place, which leads to high construction difficulty and low efficiency. This invention provides a pipeline sliding and positioning system for terrains with large elevation differences.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution: A pipeline sliding and positioning system for terrain with large elevation differences includes: The construction track is laid along the pipeline's design axis on one side of the concrete support.

[0008] Scooters, which slide along the construction track, are used to carry and transport pipes.

[0009] A lateral moving platform is slidably mounted on the construction track, and the lateral moving platform has an internal space for the scooter to enter.

[0010] The traversing platform includes a crossbeam extending above the concrete support and away from the side of the construction track.

[0011] A first movable frame is slidably mounted on the crossbeam. The first movable frame is equipped with a first pipe clamp and a first lifting mechanism for driving the first pipe clamp to rise and fall. The first pipe clamp is used to hold the pipe.

[0012] A positioning clamp is provided at the end of the crossbeam away from the construction track. The positioning clamp fixes the position of the transverse platform by clamping the side of the concrete support away from the construction track, so that when the scooter carrying the pipe enters the internal space, the pipe is aligned with the preset installation position in the axial direction.

[0013] Furthermore, the construction track is an H-shaped steel track, the scooter slides into the inner groove of the construction track, and the lateral moving platform slides into the outer groove of the construction track, forming functional zones on the inner and outer sides of the construction track.

[0014] Furthermore, the top of the scooter is provided with at least two sets of second pipe clamps along the pipe design axis for fixing the pipe to the scooter.

[0015] Furthermore, the first movable frame is provided with a first traversing trolley that drives the first movable frame to move laterally, and one first pipe clamp and one first lifting mechanism are provided at each end of the first movable frame, with the first pipe clamp suspended at the bottom of the first lifting mechanism.

[0016] Furthermore, the first movable frame includes a transverse frame and a longitudinal frame. The middle part of the transverse frame is fixedly connected to the first transverse trolley, and both ends of the transverse frame are slidably engaged with the crossbeam. The bottom of the transverse frame is slidably provided with a longitudinal frame along the pipe axis. Two first lifting mechanisms are installed at both ends of the longitudinal frame, and the transverse frame is provided with a longitudinal moving mechanism that drives the longitudinal frame to move along the pipe axis.

[0017] Furthermore, the positioning clamp includes two sets of sleeve plates, which are connected to the crossbeam. The two sets of sleeve plates are respectively used to be fitted onto the side of the top of two adjacent concrete supports away from the construction track. The bottom of the two opposite inner sidewalls of the sleeve plates are provided with side support plates, and the two side support plates are respectively used to clamp the concrete supports on the two sides along the pipeline axis.

[0018] Furthermore, a second movable frame is slidably mounted on the crossbeam. The second movable frame is located on the side of the first movable frame facing the concrete pier. A second transverse trolley is mounted on the second movable frame. A second lifting mechanism is mounted at both ends of the second movable frame. The sleeve plate is installed at the bottom of the second lifting mechanism, and an upper support plate is provided on the inner top wall of the sleeve plate for supporting the top of the concrete pier.

[0019] Furthermore, the second lifting mechanism includes a telescopic arm and a lifting frame. The telescopic arm is disposed at both ends of the second movable frame, and the lifting frame is fixedly connected between the bottom ends of the two telescopic arms. The two sleeve plates are respectively disposed at both ends of the lifting frame. The sleeve plates can slide along the axial direction of the lifting frame and are fixed to the lifting frame by a locking mechanism.

[0020] Furthermore, baffles are provided at both ends of the sleeve plate on the side away from the construction track, so that when the second moving frame moves towards the construction track, it abuts against the end face of the concrete support pier on the side away from the construction track.

[0021] Furthermore, a limit plate is provided at the front end of the lateral moving platform. After the scooter enters the internal space of the lateral moving platform, it contacts the limit plate and stops in the internal space.

[0022] Compared with the prior art, the technical solution provided by this invention has the following beneficial effects: 1) Significantly reduced the requirements for the positioning accuracy of transport equipment, and improved the system's fault tolerance: This invention utilizes a positioning clamp at the end of the crossbeam furthest from the construction track. This clamp holds the concrete support pier away from the track, fixing the transverse platform to the support. This ensures that when the scooter carrying the pipe enters the internal space, the pipe automatically aligns axially with the preset installation position. The scooter only needs to roughly stop inside the internal space, without needing to precisely stop at the lifting component. This design shifts the alignment accuracy requirement from "long-distance transportation equipment" (scooter) to "short-distance fine-tuning equipment" (transverse frame), significantly reducing the accuracy requirements for scooter positioning, increasing the system's tolerance to construction errors, and reducing operational complexity.

[0023] 2) It enabled a streamlined process for pipeline transportation and placement, significantly improving construction efficiency: This invention utilizes a collaborative mechanism between a scooter and a traversing platform—the scooter handles long-distance transport, while the first moving frame on the traversing platform handles precise positioning—and incorporates a relay mechanism between a first and second pipe clamp. This allows the scooter to immediately return to transport the next pipe after it has been clamped and lifted by the first pipe clamp, without waiting for the pipe to be lowered completely. Compared to the sequential operation mode in existing technologies where the scooter must wait for the lifting process to complete before it can be withdrawn, this invention achieves parallel transport and positioning, significantly improving construction efficiency, and is particularly suitable for projects with a large number of pipes.

[0024] 3) A two-level positioning mechanism combining coarse alignment and fine adjustment is formed to ensure positioning accuracy: The first moving frame of the present invention further includes a transverse moving frame and a longitudinal moving frame. The transverse moving frame is responsible for lateral movement (moving the pipe from the side of the concrete support to directly above the concrete support), and the longitudinal moving frame is responsible for axial movement (making axial fine adjustments to the pipe). The combination of coarse alignment (axial alignment after the positioning clamp is fixed) and fine adjustment (axial movement of the longitudinal moving frame) reduces the requirements for the parking accuracy of the scooter while ensuring the final positioning accuracy, which can reach the millimeter level.

[0025] 4) It achieves efficient utilization of construction tracks, saving construction costs: This invention uses H-beams as the construction track. The scooter slides into the inner groove of the track, and the lateral platform slides into the outer groove of the track, forming functional zones on the inner and outer sides of the track. The scooter and the lateral platform share the same track but do not interfere with each other, achieving "dual use of one track." Compared to laying two independent tracks, the amount of track used is reduced by about 50%, significantly reducing material costs and laying workload.

[0026] Furthermore, the present invention forms a three-dimensional limiting structure through a sleeve-type positioning clamp, which enhances the stability and safety of the construction system; the positioning clamp can move laterally, be raised and lowered, and have adjustable spacing to adapt to construction conditions with different concrete support sizes and spacings; the overall structure of the present invention is compact and is particularly suitable for pipeline installation operations in terrains with large elevation differences and in confined spaces.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described 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 implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] This embodiment provides a pipeline sliding and positioning system for terrains with large elevation differences. This system is particularly suitable for the transportation and installation of heating pipelines, water pipelines, and other pipelines in terrains with large elevation differences such as hills and steep slopes. It is especially suitable for confined spaces or complex terrain conditions where ground hoisting machinery cannot operate normally.

[0032] like Figures 1 to 4 As shown, the pipeline sliding and positioning system for terrain with large elevation differences includes: a construction track 1, a trolley 3, a lateral moving platform 4, a first moving frame 6, a first pipeline clamp 7, and a positioning clamp 9.

[0033] like Figure 3 and Figure 4 As shown, construction track 1 is laid along the pipeline design axis on one side of concrete support pier 2. Specifically, construction track 1 consists of two parallel tracks, located on both sides below the pipeline design axis. Construction track 1 is an H-beam steel track, which has an upper flange, a lower flange, and a web, thus forming an inner groove 101 and an outer groove 102.

[0034] The scooter 3 is mounted on the construction track 1 and is used to carry and transport the pipeline.

[0035] like Figure 1 and Figure 3 As shown, the traverse platform 4 is slidably mounted on the construction track 1, and an internal space 5 is provided inside the traverse platform 4 for the scooter 3 to enter. Specifically, the traverse platform 4 is a portal frame structure, and the internal space 5 of the traverse platform 4 refers to the area between its two side columns and below the crossbeam 401. The size of this area is designed to allow the scooter 3 and its supporting pipe to pass through. In this embodiment, a limit plate 15 is provided at the front end of the traverse platform 4. The limit plate 15 fixes the front end of the traverse platform 4 to the columns on both sides of the construction track 1. When the scooter 3 enters the internal space 5 and stops, the limit plate 15 causes the scooter 3 to stop at a predetermined position.

[0036] like Figure 3 As shown, the lateral platform 4 includes a crossbeam 401 extending above the concrete support 2 and away from the side of the construction track 1. Figure 1 and Figure 2 As shown, the crossbeam 401 extends horizontally from the main body of the transverse platform 4 toward the concrete support 2, and the end of the crossbeam 401 is located directly above the concrete support 2, and the end of the crossbeam 401 is located on the side away from the construction track 1.

[0037] like Figure 3 , Figure 4 and Figure 7 As shown, a first movable frame 6 is slidably mounted on the crossbeam 401. Specifically, the crossbeam 401 is an H-beam, and both sides of the crossbeam 401 have transverse guide grooves 16 arranged along its length. Pulleys 17 are provided at both ends of the first movable frame 6, and the pulleys 17 are located within the transverse guide grooves 16 and roll along the crossbeam 401. A first pipe clamp 7 and a first lifting mechanism 8 for driving the first pipe clamp 7 to rise and fall are provided on the first movable frame 6. The first pipe clamp 7 is used to clamp pipes. The first lifting mechanism 8 can be an electric hoist or a hydraulic cylinder; in this embodiment, the first lifting mechanism 8 is an electric hoist.

[0038] like Figures 2 to 4As shown, a positioning clamp 9 is provided at the end of the crossbeam 401 away from the construction track 1. The positioning clamp 9 fixes the position of the transverse platform 4 by clamping the side of the concrete support 2 away from the construction track 1, so that when the scooter 3 carries the pipeline into the internal space 5, the pipeline is axially aligned with the preset installation position. Specifically, after the positioning clamp 9 clamps and fixes the transverse platform 4 to the concrete support 2, the position of the transverse platform 4 relative to the concrete support 2 is locked. At this time, after the scooter 3 drives into the internal space 5 of the transverse platform 4 along the construction track 1 and stops, since the stopping position of the scooter 3 is predetermined, the axial direction of the pipeline is basically parallel to the arrangement direction of the concrete support 2, and the position of the pipeline in the length direction is basically aligned with the installation position of the concrete support 2, thus achieving axial alignment.

[0039] In this embodiment: First, construction track 1 is laid on one side of concrete supports 2 (rather than between concrete supports 2), providing a shared path for scooter 3 and traverse platform 4. Scooter 3 transports pipes from the storage area to the vicinity of the installation location along the track, while traverse platform 4, acting as a "mobile workstation," slides along the same track to the concrete support 2 to be installed.

[0040] Secondly, the positioning clamp 9 holds the side of the concrete support 2 away from the construction track 1, fixing the transverse platform 4 to the concrete support 2. Since a rigid connection is established between the transverse platform 4 and the concrete support 2, the spatial relationship between the first moving frame 6 and the first pipe clamp 7 on the transverse platform 4 and the concrete support 2 is determined. When the scooter 3 carrying the pipe enters the internal space 5 of the transverse platform 4, the pipe automatically aligns with the preset installation position axially—this is because the fixed position of the transverse platform 4 is designed based on the preset installation position of the concrete support 2; the scooter 3 only needs to enter the internal space 5 and stop, without requiring additional axial alignment adjustments.

[0041] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Reduced requirements for the positioning accuracy of the scooter 3: In the prior art, the sliding trolley must be precisely positioned at the lifting component, which requires extremely high operational precision. In this embodiment, the lateral platform 4 is fixed to the concrete support 2 by the positioning clamp 9, so that the pipeline is automatically aligned axially. The scooter 3 only needs to be parked in the internal space 5, which greatly reduces the difficulty of operation.

[0042] 2) Improve construction efficiency: The transverse platform 4 and the scooter 3 work together, with the scooter 3 responsible for long-distance transportation and the transverse platform 4 responsible for fine-tuning and positioning. The two can work in parallel.

[0043] 3) Enhanced system stability: The positioning clamp 9 rigidly connects the transverse platform 4 to the permanent concrete support 2. Compared with the independently set lifting components in the prior art, this solution has higher operational stability and stronger anti-overturning ability.

[0044] like Figure 3 and Figure 4 As shown, construction track 1 is an H-shaped steel track. The scooter 3 slides into the inner groove 101 of construction track 1, and the lateral platform 4 slides into the outer groove 102 of construction track 1, forming functional zones on the inner and outer sides of construction track 1. Figure 5 As shown, the bottom of the scooter 3 is equipped with multiple inner wheels 18. These inner wheels 18 are located in inner grooves 101 and roll along the construction track 1, thereby enabling the scooter 3 to move. Figure 6 As shown, outer traveling wheels 19 are installed at the bottom of the columns on both sides of the transverse platform 4. The outer traveling wheels 19 are located in the outer grooves 102 and roll along the construction track 1, thereby realizing the movement of the transverse platform 4. In this way, the scooter 3 and the transverse platform 4 can slide independently on the same H-shaped steel track at the same time without interfering with each other.

[0045] In this embodiment, the H-shaped steel track has a natural "I"-shaped cross-section, forming two independent sliding spaces: an inner groove 101 and an outer groove 102. The scooter 3 slides using the inner groove 101, and the traversing platform 4 slides using the outer groove 102. Both share the same track but do not interfere with each other. This design achieves "dual-use on one track"—it eliminates the need to lay two separate tracks, allowing the transport unit—the scooter 3—and the work unit—the traversing platform 4—to operate collaboratively on the same track.

[0046] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Save on construction costs: Compared to laying two independent tracks, this embodiment only requires one H-beam steel track to meet the sliding needs of two functional units, reducing the amount of track used by about 50%, which greatly reduces material costs and laying workload.

[0047] 2) Avoid mutual interference: The inner groove 101 and the outer groove 102 are spatially isolated from each other. The scooter 3 and the transverse platform 4 operate in their own independent sliding spaces, and there will be no collision or jamming, which improves the safety and reliability of the system operation.

[0048] 3) Full utilization of track cross-section: In traditional H-beam rails, only one side of the groove is used, while the other side is left unused. This solution utilizes both sides of the groove, achieving efficient use of the track cross-section.

[0049] like Figure 5As shown, at least two sets of second pipe clamps 10 are provided on the top of the scooter 3 along the pipe design axis for fixing the pipe to the scooter 3. This embodiment provides three sets of second pipe clamps 10, which are spaced apart along the length of the scooter 3. Figure 5 As shown, each set of second pipe clamps 10 includes a left half clamp 1001 and a right half clamp 1002. The bottom ends of the left half clamp 1001 and the right half clamp 1002 are rotatably mounted on both sides of the top of the scooter 3, and the top ends of the left half clamp 1001 and the right half clamp 1002 are locked by bolting. After the pipe is placed on the scooter 3, the left half clamp 1001 and the right half clamp 1002 are closed and locked to secure the pipe to the scooter 3.

[0050] In this embodiment: During pipeline transportation, the second pipeline clamp 10 securely fixes the pipeline to the scooter 3, preventing the pipeline from rolling, slipping, or falling off due to track slope or vibration during transportation. After the scooter 3 enters the internal space 5 of the transverse platform 4, the first pipeline clamp 7 clamps the pipeline, and the second pipeline clamp 10 is released, completing the transfer of the pipeline from the scooter 3 to the transverse platform 4.

[0051] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Ensuring transportation safety: In terrain with large elevation differences, the construction track 1 has a slope. The fixing function of the second pipe clamp 10 can effectively prevent the pipe from sliding or rolling during transportation, thus avoiding safety accidents.

[0052] 2) Achieve rapid handover: The second pipe clamp 10 is locked by bolting, and its opening and closing operation is relatively convenient. When used in conjunction with the first pipe clamp 7, the handover of the pipe can be completed in a short time, improving construction efficiency.

[0053] like Figure 6 and Figure 7 As shown, a first traversing trolley 11 is installed on the first movable frame 6 to drive its lateral movement. The first traversing trolley 11 is driven by a motor and can move on the crossbeam 401, thereby causing the first movable frame 6 to move along the crossbeam 401. A first pipe clamp 7 and a first lifting mechanism 8 are each provided at both ends of the first movable frame 6, with the first pipe clamp 7 suspended from the bottom of the first lifting mechanism 8. Specifically, the first movable frame 6 has a length extending along the axial direction of the pipe, and a first lifting mechanism 8 is installed at each of its left and right ends. A first pipe clamp 7 is suspended below the sling of each first lifting mechanism 8. The two first pipe clamps 7 can be raised and lowered synchronously to ensure uniform force distribution at both ends of the pipe.

[0054] In this embodiment: the first lateral trolley 11 drives the first moving frame 6 to move along the crossbeam 401, enabling the first pipe clamp 7 to move from the lateral position of the pipe to directly above the pipe, and after clamping the pipe, to move the pipe laterally from the side of the concrete support 2 to directly above the concrete support 2. Two first pipe clamps 7 are respectively located at both ends of the first moving frame 6. When the two first lifting mechanisms 8 lift synchronously, the two first pipe clamps 7 simultaneously clamp both ends of the pipe, maintaining the pipe's horizontal lifting and lowering.

[0055] like Figure 8 As shown, the first pipe clamp 7 includes a bracket 701, a left jaw 702, a right jaw 703, a lower left connecting rod 704, a lower right connecting rod 705, an upper left connecting rod 706, an upper right connecting rod 707, and a telescopic cylinder 708. The top of the bracket 701 is connected to the first lifting mechanism 8. The left jaw 702 and the right jaw 703 are arc-shaped to fit the pipe, and the tops of the left jaw 702 and the right jaw 703 are rotatably mounted on the bracket 701 in a concentric state. At the bottom, the bottom ends of the lower left connecting rod 704 and the lower right connecting rod 705 are fixedly connected to the tops of the left gripper 702 and the right gripper 703, respectively. The bottom ends of the upper left connecting rod 706 and the upper right connecting rod 707 are hinged to the tops of the lower left connecting rod 704 and the upper right connecting rod 705, respectively. The cylinder of the telescopic cylinder 708 is fixedly connected to the bracket 701. The tops of the upper left connecting rod 706 and the upper right connecting rod 707 are rotatably connected to the piston rod of the telescopic cylinder 708. When the piston rod of the telescopic cylinder 708 extends downward, the first pipe clamp 7 closes; when the piston rod of the telescopic cylinder 708 retracts upward, the first pipe clamp 7 opens.

[0056] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Achieve precise lateral positioning of the pipeline: The first lateral trolley 11 drives the first moving frame 6 to move laterally, enabling the pipeline to be precisely moved from the lateral transport position to directly above the concrete support 2, thus solving the technical problem of the pipeline needing to move laterally in the "track on one side of the concrete support 2" scheme.

[0057] 2) Ensure the stability of pipeline lifting: The first pipeline clamp 7, which is symmetrically arranged at both ends, can simultaneously clamp both ends of the long pipeline to prevent the pipeline from tilting or twisting during lifting and ensuring that the pipeline is smoothly positioned.

[0058] 3) Improve positioning accuracy: The first lateral trolley 11 can be driven by a servo motor and, in conjunction with a position sensor, can achieve precise control of the lateral movement of the pipeline.

[0059] like Figure 7As shown, the first movable frame 6 includes a transverse frame 601 and a longitudinal frame 602. The middle part of the transverse frame 601 is fixedly connected to the first transverse trolley 11, and both ends of the transverse frame 601 are slidably engaged with the crossbeam 401. The longitudinal frame 602 is slidably mounted on the bottom of the transverse frame 601 along the pipe axis. Specifically, a longitudinal guide groove 20 extending along the pipe axis is installed on the bottom of the transverse frame 601, and a slider 21 that engages with the longitudinal guide groove 20 is installed on the upper surface of the longitudinal frame 602, so that the longitudinal frame 602 can slide relative to the transverse frame 601 along the pipe axis. Two first lifting mechanisms 8 are installed at both ends of the longitudinal frame 602. A longitudinal moving mechanism for driving the longitudinal frame 602 to move along the pipe axis is provided on the transverse frame 601.

[0060] like Figure 7 As shown, in this embodiment, the longitudinal moving mechanism includes a lead screw 603, a threaded sleeve 604, and a drive motor 605. The lead screw 603 is rotatably mounted on the transverse frame 601, the drive motor 605 is mounted on the transverse frame 601, and the threaded sleeve 604 is fixedly mounted on the slider 21. The threaded sleeve 604 is threadedly engaged with the lead screw 603. When it is necessary to fine-tune the axial position of the pipe, the longitudinal moving mechanism is activated, driving the longitudinal frame 602 to move axially, thereby causing the first pipe clamp 7 and the pipe it holds to perform axial fine-tuning.

[0061] In this embodiment: the transverse moving frame 601 is responsible for lateral movement (moving the pipe from the side of the concrete support 2 to directly above the concrete support 2), and the longitudinal moving frame 602 is responsible for axial movement (making axial fine adjustments to the pipe). After the scooter 3 stops, due to the fixing effect of the positioning clamp 9, the pipe is roughly aligned with the preset installation position in the axial direction (rough alignment). However, considering factors such as the laying error of the construction track 1 and the stopping error of the scooter 3, there may be a slight deviation in the axial direction of the pipe (e.g., ±20mm). At this time, the longitudinal moving mechanism drives the longitudinal moving frame 602 to slide axially, driving the two first pipe clamps 7 and the clamped pipe to make axial fine adjustments, so that the pipe is accurately aligned with the installation position of the concrete support 2.

[0062] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) A two-level positioning mechanism is formed: coarse alignment (axial alignment after the positioning fixture 9 is fixed) + fine adjustment (axial movement of the longitudinal transfer frame 602), which reduces the requirements for the parking accuracy of the scooter 3 and ensures the final positioning accuracy.

[0063] 2) Improve system fault tolerance: Even if there is a certain error in the parking position of the scooter 3, or if there is a deviation in the laying of the construction track 1, the longitudinal shift frame 602 can compensate for it through axial fine adjustment without rework.

[0064] 3) Adaptable to different pipe lengths: The longitudinal shift frame 602 can adjust the axial distance between the two first pipe clamps 7 to adapt to pipes of different lengths, thus improving the versatility of the system.

[0065] like Figure 9 As shown, the positioning clamp 9 includes two sets of sleeve plates 901, which are connected to the crossbeam 401. The two sets of sleeve plates 901 are respectively used to fit onto the side of the top of two adjacent concrete supports 2 away from the construction track 1. Each set of sleeve plates 901 has an inverted U-shaped structure with its opening facing downwards, allowing it to cover the top of the concrete support 2. Side support plates 902 are provided at the bottom of the two opposite inner sidewalls of the sleeve plates 901. The two side support plates 902 are respectively used to clamp onto the two sides of the concrete support 2 along the pipeline axis. When the sleeve plates 901 are placed on the concrete support 2, the two side support plates 902 abut against the front and rear sides of the concrete support 2, i.e., the two sides along the pipeline axis, thereby restricting the movement of the transverse platform 4 along the pipeline axis.

[0066] In this embodiment, the distance between the two opposing inner wall surfaces of the sleeve plate 901 is greater than the thickness of the concrete pier 2. A top support threaded rod 905 is threadedly installed at the bottom of both opposing inner sidewalls of the sleeve plate 901. A side support plate 902 is rotatably installed at one end of the top support threaded rod 905 located inside the sleeve plate 901. After the sleeve plate 901 is fitted onto the top of the concrete pier 2, by rotating the top support threaded rods 905 on both sides respectively, the side support plate 902 is pressed against the concrete pier 2, thus enabling the positioning clamp 9 to hold the concrete pier 2.

[0067] In this embodiment, the sleeve plate 901 is fitted onto the top of the concrete support 2 from above, and the side support plates 902 clamp the two sides of the concrete support 2 along the pipeline axis from both sides. This structure uses the top and sides of the concrete support 2 as positioning references to achieve a rigid connection between the transverse platform 4 and the concrete support 2 in the pipeline axis, thus limiting the displacement of the transverse platform 4 in the pipeline axis.

[0068] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Achieve precise axial positioning: By fitting the sleeve plate 901 with the concrete support 2 and clamping the side support plate 902 with the side of the concrete support 2, the relative position of the transverse platform 4 and the concrete support 2 in the axial direction can be precisely fixed.

[0069] 2) Using permanent structures as construction benchmarks: The completed concrete pier 2 is used as the positioning benchmark, eliminating the need for additional positioning piles or measurement benchmarks, thus simplifying the construction preparation process.

[0070] 3) Simple structure and easy operation: The 901 sleeve plate structure only requires the sleeve plate 901 to be placed on the top of the concrete support 2, and then the top support threaded rod 905 to complete the positioning, which is quick and easy.

[0071] 4) Adapting to concrete supports of different thicknesses 2: By adjusting the length of the threaded rods 905 on both sides of the sleeve 901 extending into the sleeve 901, the positioning clamp 9 can adapt to concrete supports of different thicknesses, further improving the versatility of the system.

[0072] like Figure 6 As shown, a second movable frame 12 is slidably mounted on the crossbeam 401, located on the side of the first movable frame 6 facing the concrete pier 2. A second transverse trolley 13 is mounted on the second movable frame 12, and the structure of the second transverse trolley 13 is similar to that of the first transverse trolley 11, used to drive the second movable frame 12 to move along the crossbeam 401. A second lifting mechanism 14 is provided at both ends of the second movable frame 12. A sleeve plate 901 is installed at the bottom of the second lifting mechanism 14, and an upper support plate 903 is provided on the inner top wall of the sleeve plate 901 for supporting the top of the concrete pier 2. When the second lifting mechanism 14 descends, the upper support plate 903 presses against the top surface of the concrete pier 2, thereby forming a three-dimensional limit together with the side support plate 902, firmly fixing the transverse platform 4 to the concrete pier 2.

[0073] In this embodiment: the second traverse trolley 13 drives the second moving frame 12 to move along the crossbeam 401, so that the sleeve 901 can be aligned with the position of the concrete support 2. The second lifting mechanism 14 drives the sleeve 901 to descend, so that the sleeve 901 is fitted onto the top of the concrete support 2, while the upper support plate 903 supports the top surface of the concrete support 2. When it is necessary to release the positioning, the second lifting mechanism 14 rises, the sleeve 901 disengages from the concrete support 2, and the second moving frame 12 can then move laterally away.

[0074] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Adapting to different spacing between construction track 1 and concrete support 2: The second moving frame 12 can move along the crossbeam 401 to adjust the lateral distance between the sleeve plate 901 and the construction track 1, so that the two sets of sleeve plates 901 can adapt to different spacing between construction track 1 and concrete support 2, thus improving the versatility of the system.

[0075] 2) Achieve rapid positioning and separation: The second lifting mechanism 14 enables rapid engagement and separation of the sleeve plate 901 and the concrete support 2, which greatly improves positioning efficiency compared to manual operation.

[0076] 3) Enhance vertical stability: The upper support plate 903 is supported on the top of the concrete support pier 2 and works together with the side support plate 902 to limit the transverse platform 4 in both vertical and horizontal directions, preventing the transverse platform 4 from overturning when the pipeline moves horizontally.

[0077] like Figure 9 and Figure 10As shown, the second lifting mechanism 14 includes a telescopic arm 1401 and a lifting frame 1402. The telescopic arms 1401 are located at both ends of the second movable frame 12. Each telescopic arm 1401 is formed by two nested sleeves and can extend and retract vertically. The lifting frame 1402 is fixedly connected between the bottom ends of the two telescopic arms 1401, forming a horizontal frame. Two sleeve plates 901 are respectively located at both ends of the lifting frame 1402. The sleeve plates 901 can slide along the axial direction of the lifting frame 1402 and are fixed to the lifting frame 1402 by a locking mechanism. Specifically, the lifting frame 1402 is a long rod with a rectangular cross-section. The upper part of the sleeve plate 901 is provided with a sleeve 906 that slides with the lifting frame 1402. The sleeve 906 can slide back and forth along the lifting frame 1402 to adjust the distance between the two sleeve plates 901 to accommodate different spacings of the concrete supports 2. When the distance is adjusted to the correct position, the sleeve plate 901 is fixed to the lifting frame 1402 by the locking mechanism. In this embodiment, the locking mechanism includes a positioning bolt 907, a first pin hole 908, and a second pin hole 909. Multiple first pin holes 908 are provided at both ends of the lifting frame 1402, and the second pin hole 909 is provided on the sleeve 906. The positioning bolt 907 fixes the sleeve plate 901 to the lifting frame 1402 by passing through the second pin hole 909 and the first pin hole 908 in sequence.

[0078] The second lifting mechanism 14 can be driven by a lifting cylinder (such as...) Figure 10 The telescopic boom 1401, after being cut open, contains the lifting cylinder. The lifting cylinder is located inside the telescopic boom 1401. The cylinder body of the lifting cylinder is connected to the second moving frame 12, and the piston rod is connected to the lifting frame 1402. The lifting frame 1402 is raised and lowered by the extension and retraction of the lifting cylinder.

[0079] In this embodiment: the telescopic boom 1401 extends and retracts under the drive of the lifting cylinder, thereby raising and lowering the lifting frame 1402 and the sleeve plate 901 mounted on it. The sleeve plate 901 can slide along the axial direction of the lifting frame 1402, thereby adjusting the axial distance between the two sets of sleeve plates 901 to adapt to the spacing of different concrete supports 2. After adjustment, the sleeve plate 901 is fixed on the lifting frame 1402 by the locking mechanism to maintain the adjusted position.

[0080] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Adapting to different spacings of concrete supports 2: The sleeve plate 901 can slide and adjust along the axial direction of the lifting frame 1402, so that the same set of positioning clamps 9 can adapt to different construction conditions of concrete support 2 spacing, thus improving the versatility of the system.

[0081] 2) Smooth and reliable lifting: The telescopic boom 1401 has good guiding properties, which can ensure that the lifting frame 1402 remains horizontal during the lifting process, and avoid the sleeve plate 901 from being tilted, which would prevent it from being accurately fitted into the concrete support 2.

[0082] 3) Reliable locking: The locking mechanism can prevent the sleeve plate 901 from sliding accidentally during operation, ensuring that the connection between the positioning clamp 9 and the concrete support 2 is firm and reliable.

[0083] like Figure 6 , Figure 9 and Figure 10 As shown, baffles 904 are provided at both ends of the sleeve plate 901 on the side away from the construction track 1. The baffles 904 are horizontal plates and are fixedly installed at the ends of the sleeve plate 901. When the second moving frame 12 moves towards the construction track 1, the baffles 904 can abut against the end face of the concrete support pier 2 on the side away from the construction track 1, further enhancing the stability of the transverse moving platform 4.

[0084] In this embodiment: when the second moving frame 12 moves towards the construction track 1 (i.e., towards the main body of the transverse platform 4), the baffle 904 moves together with the sleeve plate 901, and finally abuts against the end face of the concrete support 2 away from the construction track 1. The abutment between the baffle 904 and the end face of the concrete support 2 restricts the displacement of the transverse platform 4 in the transverse direction of the pipeline (i.e., away from the construction track 1).

[0085] After applying the pipeline sliding placement system for terrains with large elevation differences in this embodiment: 1) Forming three-dimensional limiting: The baffle 904, together with the side support plate 902 (limiting axial displacement) and the upper support plate 903 (limiting vertical displacement), limit the transverse platform 4 from three orthogonal directions, ensuring that the transverse platform 4 remains stationary during the transverse movement of the pipeline.

[0086] 2) Improve lateral restraint performance: When the pipeline moves laterally, the baffle 904 abuts against the end face of the concrete support 2, and works with the construction track 1 to limit the movement of the lateral platform 4, preventing the lateral platform 4 from moving laterally.

[0087] 3) Improved operational safety: The three-dimensional limiting structure effectively prevents the transverse platform 4 from overturning or sliding during the transverse movement of the pipeline, ensuring the safety of operators and equipment.

[0088] The working process of the pipeline sliding and positioning system in terrain with large elevation differences in this embodiment is as follows: 1) Positioning of the transverse platform 4: Slide the transverse platform 4 along the construction track 1 to the pair of concrete supports 2 where the pipe to be installed is located. Activate the second lifting mechanism 14 to lower the sleeve plate 901, so that the sleeve plate 901 is fitted onto the top of the concrete support 2. The side support plates 902 clamp the axial sides of the concrete support 2, and the upper support plate 903 supports the top surface of the concrete support 2. At the same time, the baffle plate 904 abuts against the end face of the concrete support 2 away from the construction track 1. If necessary, the lateral position of the second moving frame 12 can be finely adjusted by the second transverse trolley 13, and the distance between the two sleeve plates 901 can be adjusted by sliding the sleeve plates 901 on the lifting frame 1402, so that the sleeve plates 901 are accurately aligned with the concrete support 2.

[0089] 2) Positioning of scooter 3: Place the pipe on scooter 3 and secure it with the second pipe clamp 10. Activate the traction device (e.g., a winch) to pull scooter 3 along the construction track 1, into the internal space 5 of the transverse platform 4, until scooter 3 touches the limiting plate 15 and stops. At this point, since the transverse platform 4 has been fixed to the concrete support 2 by the positioning clamp 9, and the stopping position of scooter 3 is preset, the pipe is basically aligned axially with the preset installation position (i.e., the pipe's axis is parallel to the arrangement direction of the concrete support 2, and the pipe's position in the length direction is approximately aligned with the installation position of the concrete support 2).

[0090] 3) Pipe clamping and handover: Activate the first lateral trolley 11 to move the first moving frame 6 laterally to directly above the pipe. Activate the first lifting mechanism 8 to lower the first pipe clamp 7 to the periphery of the pipe. Drive the first pipe clamp 7 to close, clamping the pipe. Subsequently, release the second pipe clamp 10 on the scooter 3, allowing the pipe to detach from the scooter 3.

[0091] 4) Pipe lifting: Simultaneously start the two first lifting mechanisms 8 to lift the first pipe clamp 7 together with the pipe, so that the bottom of the pipe is higher than the top surface of the concrete support 2, ensuring that the pipe is detached from the scooter 3.

[0092] 5) Scooter 3 return trip: The empty scooter 3 is driven out of the internal space 5 of the transverse platform 4 and returned to the starting point to transport the next pipe.

[0093] 6) Lateral movement and axial fine-tuning of the pipeline: Start the first lateral movement trolley 11, drive the first moving frame 6 to move the pipeline laterally towards the concrete support 2 until the pipeline is directly above the concrete support 2. If there is a slight deviation between the pipeline and the installation position of the concrete support 2 in the axial direction at this time, the longitudinal movement mechanism can be started to drive the longitudinal moving frame 602 to move axially, thereby performing axial fine-tuning of the pipeline until the pipeline is precisely aligned with the concrete support 2.

[0094] 7) Lowering the pipe: Simultaneously activate the two first lifting mechanisms 8 to slowly lower the pipe to the top surface of the concrete support 2, completing the pipe positioning. Afterward, release the first pipe clamp 7 and raise it back to its original position.

[0095] 8) Transfer of transverse platform 4: Disconnect the positioning clamp 9 from the concrete support 2, slide the transverse platform 4 along the construction track 1 to the next pair of concrete supports 2, and repeat the above steps.

[0096] In summary, the pipeline sliding and positioning system for terrains with large elevation differences provided in this embodiment effectively reduces the requirements for the positioning accuracy of transportation equipment through the coordinated mechanisms of functional zoning of the inner and outer sides of the construction track 1, fixing and axial alignment of the positioning clamp 9, relay of the first pipeline clamp 7 and the second pipeline clamp 10, and two-level positioning. It realizes the assembly line operation of transportation and positioning, and has the advantages of compact structure, strong adaptability and high construction efficiency. It is particularly suitable for pipeline installation projects in mountainous and hilly terrains with large elevation differences and has industrial applicability.
