Description

Technical Field

[0001] This invention relates to the field of pipeline installation auxiliary equipment technology, specifically to a pipeline installation device and its usage method based on a lifting vehicle. Background Technology

[0002] In modern building engineering, municipal infrastructure construction, and industrial plant construction, high-altitude pipeline installation is a core component ensuring the functionality of building water supply and drainage, heating and ventilation, gas transmission, and industrial fluid transport. With continuous increases in building height, diversification of pipeline specifications (such as large-diameter pipes and irregularly shaped fittings), and more complex construction environments (such as confined spaces and strong winds at high altitudes), higher demands are placed on the precision, safety, and efficiency of pipeline installation.

[0003] Currently, the mainstream method for high-altitude pipeline installation in the industry is still "lifting platform + manual assistance." This involves using the lifting platform of the lifting platform to transport the pipeline to the designated height, where 2-3 workers then manually support and tie the pipeline to the ground to complete the connection. While this method meets basic installation requirements, it suffers from several technical bottlenecks: First, poor stability and high safety risks. Lifting platforms are mostly planar structures, lacking dedicated limiting mechanisms for cylindrical pipelines. Pipelines are prone to rolling or slipping due to platform vibration and wind interference, potentially causing pipeline damage and posing a life-threatening risk to personnel below. Second, insufficient adjustment flexibility and poor adaptability. Existing lifting platforms can only achieve overall height adjustment, unable to make precise adjustments to the local height and horizontal position for pipelines of different lengths and diameters or for irregularly shaped fittings such as tees. This results in low pipeline connection accuracy, requiring repeated corrections and low construction efficiency. Third, high labor costs and low operational safety. To ensure pipeline stability, additional manpower is required for auxiliary fixing. In high-altitude operations, workers must simultaneously perform fixing and connection operations on a confined platform, increasing the risk of falls due to loss of balance. Furthermore, the lack of consistency in manual operation makes it difficult to guarantee the stability of installation quality. Fourthly, the system has poor adaptability to complex working conditions. When faced with complex scenarios such as the installation of pipelines with tees, existing equipment cannot provide multi-point, multi-angle support and adjustment, requiring multiple adjustments to the position of the lifting platform and even the erection of temporary scaffolding, which prolongs the construction period and increases construction costs.

[0004] These problems not only hinder the improvement of the quality and efficiency of high-altitude pipeline installation operations, but also contradict the core requirements of modern engineering construction: "high efficiency, safety, and low cost." Therefore, there is an urgent need for a pipeline installation device with a dedicated support structure, precise adjustment function, adaptability to complex working conditions, and reduced manpower input, in order to overcome the current technological bottlenecks. Summary of the Invention

[0005] The purpose of this invention is to provide a pipeline installation device and its usage method based on a lifting vehicle. This device effectively solves the problems of unstable pipeline fixing, inconvenient adjustment, high labor costs, and poor adaptability to complex working conditions in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A pipeline installation device based on a lifting vehicle includes a lifting vehicle assembly, a first adjustment platform, and a second adjustment platform; a first adjustment platform is provided on one side of the lifting vehicle assembly, and a first adjustment platform or a second adjustment platform is provided on the other side of the lifting vehicle assembly. The first adjustment platform includes a first lower rod, a first upper rod, a first support member, a first linear drive member, a first controller, and a connector. The first lower rod is detachably mounted on the lifting vehicle unit via the connector. The first upper rod is slidably mounted inside the first lower rod. The first support member is fixedly mounted on the top of the first upper rod. One end of the first linear drive member is fixedly located at the bottom of the first lower rod, and the other end of the first linear drive member is connected to the first upper rod. The first controller is mounted on the first lower rod. The second adjustment platform includes a connecting plate, a bottom support plate, a second lower rod, a second upper rod, a second support member, a second linear drive member, and a second controller. The connecting plate is detachably mounted on the lifting vehicle assembly. The bottom support plate is slidably mounted on the connecting plate. The second lower rod is fixedly mounted on the bottom support plate. The second upper rod is slidably mounted inside the second lower rod. The second support member is fixedly mounted on the top of the second upper rod. One end of the second linear drive member is mounted on the connecting plate, and the other end of the second linear drive member is connected to the second lower rod or the bottom support plate. The second controller is mounted on the second lower rod.

[0007] Preferably, the lifting vehicle assembly includes a vehicle body, a lifting device, and an operating platform. The lifting device is mounted on the vehicle body, and the operating platform is mounted on the lifting device. The lifting of the operating platform is controlled by controlling the lifting of the lifting device.

[0008] Preferably, the first adjustment platform and the second adjustment platform are disposed on the operating platform.

[0009] Preferably, the first support member and the second support member have the same structure, both being U-shaped.

[0010] Preferably, two slide rails are fixedly installed on one side of the connecting plate, and the bottom support plate is slidably installed on the two slide rails; one cantilevered end of the slide rail is connected to the connecting plate through a diagonal brace.

[0011] Preferably, a second linear drive member is provided between the bottom of the second lower rod and the bottom of the connecting plate; a second linear drive member is provided between the connecting plate and the bottom support plate; and two second linear drive members are provided in a V-shape between the top of the connecting plate and the second lower rod.

[0012] Preferably, a through hole is provided on the bottom support plate, and a third linear drive is fixedly installed at the bottom of the bottom support plate. The extended end of the third linear drive is connected to the second upper rod. When the third linear drive is energized to extend or retract, it controls the vertical lifting and lowering of the second upper rod.

[0013] Preferably, the first support member includes a first L-shaped rod and a second L-shaped rod, one end of the first L-shaped rod is fixedly installed on the top of the first upper rod, and one end of the second L-shaped rod is slidably installed inside one end of the first L-shaped rod.

[0014] A method for using a pipe installation device assisted by a lifting vehicle, the method comprising the following steps: Step 1: Assembly of the device. Under normal operating conditions, a first adjustment platform is installed on one side of the lifting vehicle and a second adjustment platform is installed on the other side of the lifting vehicle. Under installation conditions with a T-junction, a second adjustment platform is installed on both sides of the lifting vehicle. Step two, pipe assembly: control the lifting vehicle to move into position, adjust the first or second adjustment platform to be below the pipe to be installed, fine-tune the height of the first and second adjustment platforms, and assemble the two sections of pipe to be installed.

[0015] In this invention, the combined structural design of "lifting vehicle group + first adjustment platform + second adjustment platform" and the sophisticated drive and control components effectively solve the problems of unstable pipeline fixation, inconvenient adjustment, high labor costs and poor adaptability to complex working conditions in the prior art.

[0016] Both the first support component of the first adjustment platform and the second support component of the second adjustment platform adopt a U-shaped structure, which can form a close-fitting wrap-around support with the cylindrical pipe. Compared with traditional planar support or rope binding, this greatly increases the contact area between the pipe and the support component, preventing the pipe from rolling or slipping due to vibration or wind. At the same time, the first support component, through the design of "first L-shaped rod + sliding second L-shaped rod", can flexibly adjust the support spacing according to the pipe diameter, further improving adaptability and fixation stability, fundamentally reducing the risk of pipe falling and ensuring the safety of construction personnel and equipment.

[0017] On the one hand, the first adjustment platform drives the first upper rod to slide within the first lower rod via a first linear drive component, enabling precise vertical height adjustment. The second adjustment platform, through the sliding of the bottom support plate on the connecting plate rail, combined with the multi-point arrangement of the second linear drive component (such as between the connecting plate and the bottom support plate, and between the second lower rod and the connecting plate), achieves flexible horizontal position adjustment. The V-shaped arrangement of the drive component enhances structural stability, and the third linear drive component allows for independent vertical lifting and lowering of the second upper rod, meeting local height fine-tuning needs. On the other hand, the operating platform of the lifting unit provides a stable installation foundation for the adjustment platform. The overall height adjustment is achieved through the lifting device, complementing the local adjustments of the adjustment platform. This allows for rapid adjustment of the pipeline to the docking position, significantly reducing manual corrections and improving pipeline docking accuracy and construction efficiency.

[0018] The design, featuring a flexible combination of a first and second adjustment platform, is adaptable to various construction scenarios. In conventional pipeline installation, the first adjustment platform is installed on one side of the lifting unit, and the second adjustment platform on the other, satisfying both foundation support adjustment needs and cost control. In complex pipeline installations with tees, the second adjustment platform is installed on both sides, utilizing its horizontal and vertical adjustment capabilities to provide multi-point support for the tee fittings without requiring adjustments to the lifting unit's position or the construction of temporary auxiliary structures, significantly improving adaptability to complex conditions. Furthermore, the second adjustment platform, by horizontally adjusting the position of its bottom support plate, enables auxiliary operations in confined spaces inaccessible to the lifting unit, further enhancing the device's versatility.

[0020] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 5 The pipeline installation device based on a lifting vehicle includes a lifting vehicle group 1, a first adjusting platform 2, and a second adjusting platform 3. A first adjusting platform 2 is set on one side of the lifting vehicle group 1, and a first adjusting platform 2 or a second adjusting platform 3 is set on the other side of the lifting vehicle group 1, depending on the specific working conditions.

[0021] The scissor lift unit 1 includes a vehicle body 10, a lifting device 11, and an operating platform 12. The lifting device 11 is mounted on the vehicle body 10, and the operating platform 12 is mounted on the lifting device 11. During operation, the operator controls the lifting of the operating platform 12 by controlling the lifting of the lifting device 11. The operator stands inside the operating platform 12 to perform the work. The scissor lift unit 1 is a mobile scissor lift purchased for construction.

[0022] The first adjustment platform 2 and the second adjustment platform 3 are located on opposite sides of the operating platform 12.

[0023] The first adjustment platform 2 includes a first lower rod 20, a first upper rod 21, a first support member 22, a first linear drive member 23, a first controller 24, and a connector 25. The first lower rod 20 is detachably mounted on the lifting vehicle group 1 through multiple connectors 25, which are L-shaped clips, U-shaped clips, or fastening bolts.

[0024] The first upper rod 21 is slidably installed inside the first lower rod 20. The first support member 22 is fixedly installed on the top of the first upper rod 21. One end of the first linear drive member 23 is fixedly installed at the bottom of the first lower rod 20, and the other end of the first linear drive member 23 is fixedly connected to the bottom of the first upper rod 21. The first controller 24 is installed on the first lower rod 20.

[0025] The first linear drive unit 23 is selected as an electric push rod or a hydraulic rod, and the first controller 24 consists of two switch buttons that control the extension and retraction of the first linear drive unit 23.

[0026] The second adjustment platform 3 includes a connecting plate 30, a bottom support plate 31, a second lower rod 32, a second upper rod 33, a second support member 34, a second linear drive member 35, and a second controller 36. The connecting plate 30 can be detachably installed on the lifting vehicle group 1 by means of L-shaped clips, U-shaped clips, or fastening bolts.

[0027] The bottom support plate 31 is slidably mounted on the connecting plate 30. Specifically, two slide rails 4 are fixedly installed at intervals on one side of the connecting plate 30, and the bottom support plate 31 is slidably mounted on the two slide rails 4. One cantilevered end of the slide rail 4 is connected to the connecting plate 30 through a diagonal brace 5, which provides diagonal support to the slide rail 4, thereby improving the load-bearing capacity of the bottom support plate 31. Operators can temporarily stand on the bottom support plate 31 to perform their work.

[0028] The second lower rod 32 is fixedly mounted on the bottom support plate 31, and the second upper rod 33 is slidably mounted inside the second lower rod 32. In a preferred embodiment, a through hole is provided on the bottom support plate 31, which is located inside the second lower rod 32. A third linear drive (not shown in the figure, with the same overall structure as the first adjusting platform 2) is fixedly mounted at the bottom of the bottom support plate 31. The extended end of the third linear drive is fixedly connected to the second upper rod 33. When the third linear drive is energized and extends or retracts, it controls the vertical lifting and lowering of the second upper rod 33. The third linear drive can be an electric push rod or a hydraulic rod.

[0029] The second support member 34 is fixedly installed on the top of the second upper rod 33.

One end of the first L-shaped rod 220 is fixedly installed on the top of the first upper rod 21, and one end of the second L-shaped rod 221 is slidably installed inside one end of the first L-shaped rod 220. After the first support member 22 or the second support member 34 is placed below the pipe to be installed, the first L-shaped rod 220 and the second L-shaped rod 221 are fastened together by set screws or bolts, which can reliably clamp the pipe to be installed.

[0030] One end of the second linear drive member 35 is mounted on the connecting plate 30, and the other end of the second linear drive member 35 is connected to the second lower rod 32 or the bottom support plate 31, for driving the second lower rod 32 to move closer to or away from the connecting plate 30. The second controller 36 is mounted on the second lower rod 32, and the second controller 36 controls the second linear drive member 35 and the third linear drive member.

[0031] Specifically, a second linear drive member 35 is provided between the bottom of the second lower rod 32 and the bottom of the connecting plate 30; a second linear drive member 35 is provided between the connecting plate 30 and the bottom support plate 31; and two second linear drive members 35 are provided in a V-shape between the top of the connecting plate 30 and the second lower rod 32. The four second linear drive members 35 are linked together, causing the bottom support plate 31 to move away from or closer to the connecting plate 30.

[0032] like Figures 1 to 5 The illustrated method of using a pipe installation device based on a lift truck includes the following steps: Step 1: Assembly of the device. During normal operation, a first adjusting platform 2 is installed on one side of the lifting unit 1, and a second adjusting platform 3 is installed on the other side. In installations with a tee, i.e., when the tee is installed between two pipe sections, a second adjusting platform 3 is installed on both sides of the lifting unit 1.

[0033] Step two, pipe assembly: The operator controls the lifting vehicle 1 to move into position, adjusts the first adjustment platform 2 or the second adjustment platform 3 to be directly below the pipe to be installed, fine-tunes the height of the first adjustment platform 2 and the second adjustment platform 3, and assembles the two sections of pipe to be installed.

[0034] The above embodiments are merely illustrative of the concept and implementation of the present invention and are not intended to limit it. Under the concept of the present invention, technical solutions without substantial changes are still within the scope of protection.
