Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, specifically to a lifting device for long-distance pipeline installation. Background Technology

[0002] Long-distance pipelines are crucial infrastructure for transporting fluid media such as oil, natural gas, and chemical raw materials over long distances. During the construction of long-distance pipelines, on-site handling, connection and adjustment, and laying are key processes. As long-distance pipeline projects develop towards larger diameters, higher pressures, and longer distances, pipeline construction places higher demands on the mechanization, intelligence, and environmental friendliness of handling and auxiliary equipment.

[0003] Long-distance pipelines, as core infrastructure for the long-distance transportation of media such as oil, gas, and water, often require the use of lifting devices for alignment and installation during construction. Existing lifting devices mostly employ a fixed structure design, making it difficult to adjust them in multiple dimensions according to the terrain conditions of the construction site. The pipeline alignment process necessitates multiple adjustments to the device's position, adversely affecting construction accuracy. Furthermore, the device relies on its own weight for stability during operation, making it prone to slippage and swaying when supporting the pipeline, posing certain operational safety hazards.

[0004] Existing technology can only achieve vertical lifting of pipelines, but cannot complete horizontal movement, rotation adjustment and precise alignment. It is difficult to control multiple actions, which limits the accuracy and efficiency of construction. Summary of the Invention

A battery rack is fixedly connected to the outer wall of the side of the second limiting ring. A solar panel is fixedly connected to the outer wall of the top of the battery rack. A motor is fixedly connected to the outer wall of the left side of the battery rack. A bidirectional threaded rod is fixedly connected to the output end of the motor via a coupling. A threaded sleeve is threadedly connected to the outer wall of the side of the bidirectional threaded rod. A scraper is fixedly connected to the outer wall of the top of the threaded sleeve.

[0008] Preferably, the auxiliary mechanism includes a spring damper, which is fixedly connected to the bottom outer wall of the support plate. The output end of the spring damper is fixedly connected to a drive motor housing frame, and the bottom inner wall of the drive motor housing frame is provided with a silicone scraper.

[0009] Preferably, a tripod is fixedly connected to the outer walls of the left and right sides of the frame, and the bottom outer wall of the tripod is fixedly connected to the top outer wall of the support plate.

[0010] Preferably, the sliding plate is slidably connected to the bottom inner wall of the top frame, and a pipe clamp is fixedly connected to the bottom outer wall of the sliding plate. There are two first compression springs, and the ends of the two first compression springs away from the first limiting ring are fixedly connected to the left inner wall of the rotating rod.

[0011] Preferably, a tire is fixedly connected to the outer side wall of the wheel hub, and multiple barbs are fixedly connected to the outer side wall of the first limiting ring near the top frame, with the barbs engaging with the inner left side wall of the top frame.

[0012] Preferably, there are several barbs, and the barbs are also fixedly connected to the left outer wall of the second limiting ring, and the end of the second compression spring away from the second limiting ring is fixedly connected to the right inner wall of the rotating column.

[0013] Preferably, the threaded sleeve is slidably connected to the top inner wall of the battery rack, the length of the scraper is adapted to the width of the solar panel, and the scraper contacts the top outer wall of the solar panel.

[0014] Preferably, the battery rack has a power supply expansion port on the left outer wall, and the battery rack is rotatably connected to the left and right inner walls of the top frame.

[0015] Preferably, the wheel hub is fixedly connected to the output end of the drive motor housing frame via a coupling, the wheel hub is rotatably connected to the inner side wall of the drive motor housing frame, and the tire contacts the inner side wall of the silicone scraper.

[0016] Working principle: The support plate 38 and frame 1 are moved to the required direction and angle via the hub 39. Simultaneously, the hydraulic jack 310 extends the stabilizing plate 311, providing periodic support for the support plate 38. The height of the pipe clamp 35 is adjusted by pulling the first limit ring 36 away from the surface of the top frame 2, then rotating the first limit ring 36 to rotate the rotating rod 32. The rotation of the rotating rod 32 drives the threaded groove 33 to rotate, which in turn moves the sliding plate 34. The sliding plate 34 then adjusts the horizontal position of the pipe clamp 35, allowing for multi-faceted adjustment in direction, angle, verticality, and horizontality to adapt to different site conditions. Furthermore, the solar panel 45 provides power during sunny days. The battery rack 44 stores and charges the battery, and also supplies power to the drive unit housing 52. When the wheel hub 39 is climbing or on a steep slope, the drive unit housing 52 is opened to rotate the wheel hub 39, allowing personnel to move and adjust the frame 1. During the movement, the spring damper 51 buffers and reduces shocks to the drive unit housing 52 and the wheel hub 39, preventing severe vibrations that could damage other components on the frame 1. The motor 46 is turned on to rotate the bidirectional threaded rod 47, which in turn moves the threaded sleeve block 48. The movement of the threaded sleeve block 48 moves the scraper 49, which removes impurities from the surface of the solar panel 45, preventing dirt from obstructing the solar panel 45 and affecting normal energy conversion.

[0017] This invention provides a lifting device for installing long-distance pipelines. It has the following advantages:

[0018] 1. This invention achieves multi-dimensional precise adjustment and reliable locking of the operation status of pipeline installation through the adjustment mechanism. It can complete the horizontal displacement adjustment of the pipeline and the vertical support conversion of the entire device, adapting to the pipeline erection requirements under different terrain conditions. It effectively solves the problems of low positioning accuracy and easy slippage and shaking during operation of traditional lifting devices, and significantly improves the construction accuracy and operation safety of long-distance pipeline installation.

[0019] 2. This invention achieves autonomous power supply of clean energy, automated cleaning of solar panels, and intelligent collaborative operation of the device through an extended mechanism. It uses solar energy to convert into electrical energy to power the device, eliminating dependence on the external power grid. At the same time, the self-cleaning structure promptly removes obstructions and impurities from the surface of the solar panels, ensuring continuous and stable photoelectric conversion efficiency. The integrated Internet of Things communication module enables remote monitoring, location tracking, and fault diagnosis of the device. It also supports master-slave collaborative control and synchronous operation between multiple devices, eliminating the need for frequent manual maintenance and significantly improving construction efficiency and management level.

[0020] 3. This invention improves the mobility and component protection of the device through auxiliary mechanisms. Equipped with an electric assisted walking system, it reduces the labor intensity of personnel pushing the device and facilitates the relocation of the device in complex terrain. At the same time, the shock-absorbing and buffering structure absorbs the vibration and impact during the movement, and the tire self-cleaning structure prevents the adhesion of debris, effectively avoiding damage to the device components due to vibration or foreign object intrusion, and extending the service life of the device.

An auxiliary mechanism 5 is provided on the adjustment mechanism 3. The adjustment mechanism 3 includes a rotating rod 32, which is rotatably connected to the inner walls of the left and right sides of the top frame 2 via bearings. A threaded groove 33 is formed on the outer side wall of the rotating rod 32, forming a threaded transmission pair with a sliding plate 34 to achieve precise conversion from rotational motion to linear motion. The sliding plate 34 is threadedly connected to the outer side wall of the threaded groove 33. A first limiting ring 36 is slidably connected to the inner left side wall of the rotating rod 32 to lock the rotation state of the rotating rod 32 and prevent... To prevent the pipe clamp 35 from shifting unexpectedly while carrying the pipeline, a first compression spring 37 is fixedly connected to the left outer wall of the first limiting ring 36, and a support plate 38 is fixedly connected to the bottom outer wall of the frame 1 to increase the contact area between the device and the ground, distribute the overall weight of the device, and improve the stability of the device when it is placed. A hub 39 is in contact with the bottom inner wall of the support plate 38, and a hydraulic jack 310 is fixedly connected to the bottom inner wall of the frame 1 to provide vertical lifting force and realize the lifting and adjustment of the support plate 311. The output end of the hydraulic jack 310 is fixedly connected to the support plate 311, and after being lifted, it is in close contact with the ground, replacing the hub 39 to bear the weight of the device and completely eliminating the risk of slippage during device operation.

[0025] Please see the appendix Figure 2 -Appendix Figure 4 Tripods 31 are fixedly connected to the outer walls of the left and right sides of the frame 1. The bottom outer wall of the tripods 31 is fixedly connected to the top outer wall of the support plate 38, increasing the contact area between the device and the ground, distributing the overall weight of the device, and improving the stability of the device during placement. A sliding plate 34 is slidably connected to the bottom inner wall of the top frame 2. A pipe clamp 35 is fixedly connected to the bottom outer wall of the sliding plate 34 for clamping and fixing long-distance pipelines, enabling the lifting and alignment of the pipelines during installation. There are two first compression springs 37. The ends of the two first compression springs 37 away from the first limiting ring 36 are fixedly connected to the left inner wall of the rotating rod 32. The hub 39... Tires are fixedly connected to the outer side wall to increase friction with the ground and improve the device's passability on muddy and soft ground. At the same time, it further buffers ground vibrations. This is an improvement over existing technology where the walking wheels are rigidly connected without any shock absorption mechanism. When moving on uneven roads in the field, the ground bumps are directly transmitted to the pipes and the device, causing damage to the anti-corrosion layer of the pipes and impact loads on the hydraulic system, affecting the service life of the equipment. Multiple barbs are fixedly connected to the outer wall of the first limiting ring 36 near the top frame 2. They are embedded in the inner wall of the top frame 2 to form a mechanical lock, which greatly improves the reliability of the locking state of the rotating rod 32. The barbs are engaged with the inner wall of the left side of the top frame 2.

[0026] Please see the appendix Figure 4 -Appendix Figure 6The expansion mechanism 4 includes a rotating column 41, which is rotatably connected to the inner walls of the left and right sides of the top frame 2 via bearings. A second limiting ring 42 is slidably connected to the inner wall of the right side of the rotating column 41 to lock the rotation state of the rotating column 41 and prevent the solar panel 45 from shifting at an angle under wind force. A second compression spring 43 is fixedly connected to the outer wall of the right side of the second limiting ring 42. A battery rack 44 is fixedly connected to the outer wall of the side of the second limiting ring 42. A solar panel 45 is fixedly connected to the outer wall of the top of the battery rack 44 to convert solar energy into electrical energy to charge the battery. This enables the device to operate without a power grid in the field, improving upon existing technologies that rely on continuous external power input, lack energy storage and management functions, and cannot recover and utilize the kinetic energy generated during downhill driving or braking, resulting in low energy utilization. This reduces the passive situation of energy depletion during operation. The battery rack 44... A motor 46 is fixedly connected to the left outer wall. The output end of the motor 46 is fixedly connected to a bidirectional threaded rod 47 via a coupling. A threaded sleeve block 48 is threadedly connected to the side outer wall of the bidirectional threaded rod 47. A scraper 49 is fixedly connected to the top outer wall of the threaded sleeve block 48. Several barbs are present. Several barbs are also fixedly connected to the left outer wall of the second limiting ring 42. The end of the second compression spring 43 away from the second limiting ring 42 is fixedly connected to the right inner wall of the rotating column 41. The threaded sleeve block 48 is slidably connected to the top inner wall of the battery rack 44. The battery rack 44 also integrates an Internet of Things (IoT) communication module. Through the cloud platform, remote monitoring, location tracking, and fault diagnosis of the device are realized. Through the IoT communication module, master-slave collaborative control and synchronous operation between multiple devices are realized, improving the existing technology of independently operating electromechanical equipment that does not have any data communication and remote monitoring functions. Managers cannot remotely obtain the equipment's operating status, location information, and work progress. When equipment malfunctions, they cannot obtain fault information in a timely manner and perform remote diagnosis, resulting in low maintenance efficiency. The length of the scraper 49 is matched with the width of the solar panel 45. When it moves with the threaded sleeve 48, it scrapes away dust, fallen leaves, and other impurities from the surface of the solar panel 45, ensuring solar energy conversion efficiency. Through the cooperation of the solar panel and the battery, the device achieves autonomous energy supply and optimized management, eliminating dependence on external power sources and improving energy utilization. The scraper 49 contacts the top outer wall of the solar panel 45. The left outer wall of the battery rack 44 has a power supply expansion port. The battery rack 44 is rotatably connected to the left and right inner walls of the top frame 2.

[0027] Please see the appendix Figure 5 -Appendix Figure 7The auxiliary mechanism 5 includes a spring damper 51, which is fixedly connected to the bottom outer wall of the support plate 38. It absorbs the vibration energy generated during the movement of the device and reduces the impact damage of vibration to the precision components on the frame 1. The output end of the spring damper 51 is fixedly connected to the drive motor housing frame 52. The bottom inner wall of the drive motor housing frame 52 is provided with a silicone scraper 53. The wheel hub 39 is fixedly connected to the output end of the drive motor housing frame 52 through a coupling. The wheel hub 39 is rotatably connected to the side inner wall of the drive motor housing frame 52. The tire contacts the side inner wall of the silicone scraper 53. When the wheel hub 39 rotates, it scrapes off the mud and gravel adhering to the tire surface to prevent debris from entering the drive motor and causing malfunctions.

[0028] Example 2: Please refer to the attached document. Figure 8 The difference from Embodiment 1 lies in the change of the driving method of the rotating rod 32. The extension mechanism 4 includes a servo motor 410. The output shaft of the servo motor 410 is fixedly connected to the end of the rotating rod 32. The servo motor 410 is electrically connected to a remote controller. The opening and closing of the servo motor 410 is controlled by the external remote controller to control the lateral position of the pipe clamp 35. An electric hoist 411 is threadedly connected to the rotating rod 32 through a threaded block. The electric hoist 411 is fixedly connected to the pipe clamp 35 through a cable or cable. The pipe clamp 35 can be replaced according to the change of pipe diameter.
