Description

Technical Field

[0001] This invention relates to the field of pipeline transportation, and more particularly to a method for high-altitude pipeline transportation. Background Technology

[0002] In industrial projects, high-altitude pipeline welding and transportation are currently unavoidable. Existing installation methods include the following:

[0003] Support bracket fixing method: First, install and fix supports and hangers on a high-altitude working surface, such as the roof slab or steel structure of a pipe gallery, and then place and connect the pipes section by section. This method has obvious disadvantages, such as extremely high requirements for the working surface and supports, the need to build a stable platform, a small range of pipe diameters that can be used, difficulty in installing both lighter and larger pipes, low work efficiency, and high modification costs, etc.

[0004] Modular integrated hoisting method: Pipes, supports, valves, etc. are pre-assembled into complete modules on the ground, and then hoisted as a whole to a high altitude, with interfaces reserved at the altitude for connection. This method is suitable for most pipeline transportation and installation, but it has significant safety hazards. The weight of the integrated module is easily excessive, which can cause swaying during hoisting, threatening the lives of hoisting personnel. It also requires high-end hoisting equipment, is slow, and has high costs.

[0005] Therefore, current pipeline transportation and installation costs are high and efficiency is low, making it impossible to balance the mechanical equipment requirements of light and heavy pipelines. Summary of the Invention

[0006] To address the above problems, this invention proposes a method for high-altitude pipeline transportation, which improves the efficiency of high-altitude pipeline transportation, reduces the construction work area, and lowers the risk of safety accidents.

[0007] This application proposes a method for high-altitude pipeline transportation, characterized by comprising:

[0008] S001. Construct high-altitude pipeline support and power unit;

[0009] S002. Hoist the first section of pipe into the inlet of the high-altitude pipe support, and fix the power head of the power unit to the beginning of the pipe.

[0010] S003. Hoist the next section of pipe to the end of the previous section of pipe and weld it to the previous section of pipe. Move the welded pipe as a whole a certain distance in the direction of transportation.

[0011] S004. Repeat step S003 to hoist the nth section of pipe until the last section of pipe is welded.

[0012] Furthermore, the high-altitude pipeline support includes columns and a transport channel. Multiple columns are fixedly supported below the transport channel, and the pipeline is transported from above the transport channel. The columns are perpendicular to the plane of the transport channel.

[0013] Furthermore, the transport channel includes support rods and connecting rods, with multiple support rods arranged parallel to each other at a certain distance, and the connecting rods perpendicular to the support rods connecting the multiple support rods; the column is located at the intersection of the connecting rod and the support rod.

[0014] Furthermore, the distance between two adjacent support rods is less than the length of each segment of the pipe.

[0015] Furthermore, the method also includes a lifting device. During the hoisting process in step S002, the pipe needs to be placed on the lifting device, which is then raised to the height of the transport channel. Construction workers then move the pipe to be installed and welded onto the transport channel.

[0016] Furthermore, the lifting device is positioned below the entrance of the aerial support structure, located on one side of the aerial support structure.

[0017] Furthermore, a guardrail is installed on the side of the transport channel away from the lifting device, and the guardrail is perpendicular to the plane of the support rod.

[0018] Furthermore, in step S003, the distance the welded pipe as a whole moves is the length of a section of the pipe.

[0019] Furthermore, the power unit includes a power head, a traction wheel, a traction rope, and a drive device.

[0020] The power head is installed at the beginning of the entire pipeline, and the traction wheel is fixed at the outlet of the high-altitude pipeline support at a certain distance from the outlet.

[0021] The traction rope is wound around the traction wheel. One end of the traction rope is fixed to the power head, and the other end is connected to the drive device. The drive device pulls the traction rope, thereby driving the entire pipeline to move in the transportation direction.

[0022] Furthermore, the traction wheel and the pipe are on the same horizontal plane, the drive device is located below the traction wheel, and the traction rope changes direction through the traction wheel.

[0023] The beneficial effects of this invention are as follows: the invention is highly safe to operate, allowing workers to work at one point without having to move back and forth, reducing the occurrence of accidents such as falls from heights and lowering safety risks; the device is simple, easy to hoist, and easy to install and transport pipelines at heights; it improves work efficiency and reduces labor costs.

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other implementations obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. In the various drawings, the same elements are represented by the same or similar reference numerals, and for clarity, the various parts in the drawings are not drawn to scale.

[0030] See Figure 1-3 As shown, this invention proposes a method for high-altitude pipeline transportation, characterized by comprising:

[0031] S001. Construct high-altitude pipeline support and power unit;

[0032] S002. Hoist the first section of pipe into the inlet of the high-altitude pipe support, and fix the power head of the power unit to the beginning of the pipe.

[0033] S003. Hoist the next section of pipe to the end of the previous section of pipe and weld it to the previous section of pipe. Move the welded pipe as a whole a certain distance in the direction of transportation.

[0034] S004. Repeat step S003 to hoist the nth section of pipe until the last section of pipe is welded.

[0035] See Figure 2 , 3 As shown, specifically, the high-altitude pipeline support 1 includes columns 11 and a transport channel 12. Multiple columns 11 are fixedly supported below the transport channel 12, and the pipeline 4 is transported above the transport channel 12. The columns 11 are perpendicular to the plane of the transport channel 12. Specifically, the transport channel 12 includes support rods 121 and connecting rods 122. Multiple support rods 121 are arranged parallel to each other at a certain distance, and the connecting rods 122 connect the multiple support rods 121 perpendicularly to them. The columns 11 are located at the intersection of the connecting rods 122 and the support rods 121. In this embodiment, the columns 11 are made of high-strength steel, capable of withstanding significant pressure and tension, ensuring the stability of the entire high-altitude pipeline support 1. The connecting rods 122 connect the support rods 121 on both sides, and together with the support rods 121 and connecting rods 122, they form a stable frame structure, further improving the load-bearing capacity of the transport channel 12.

[0036] See Figure 2 As shown, specifically, the distance between two adjacent support rods 121 is less than the length of each section of the pipe. Specifically, a guardrail 13 is installed on the side of the transport channel 12 away from the lifting device 3, and the guardrail 13 is perpendicular to the plane of the support rods 121. In this embodiment, the guardrail 13 is formed by interlacing and welding multiple vertical and horizontal rods, and its height is set according to the specifications and safety requirements of the actual transport pipe, effectively preventing the pipe from sliding out of the transport channel 12 during transportation due to unexpected circumstances.

[0037] See Figure 2As shown, specifically, the method further includes a lifting device 3. During hoisting in step S002, the pipe 4 needs to be placed on the lifting device 3. The lifting device 3 is raised to the height of the transport channel 12, and the construction personnel move the pipe 4 to be installed and welded onto the transport channel 12. Specifically, the lifting device 3 is positioned below the entrance 101 of the aerial support, located on one side of the aerial support. Specifically, in step S003, the distance the welded pipe 4 moves as a whole is the length of a section of pipe. In this embodiment, the lifting device 3 is placed in front of the aerial pipe support 1, and the construction personnel are positioned on the lifting device 3. As the lifting device 3 rises to the height of the transport channel 12, the joint 42 of each pipe 4 is welded at the entrance 101 of the aerial pipe support 1. The joint 42 is the connection point between the tail of the previous section of pipe 4 and the head of the next section of pipe 4.

[0038] See Figure 2 As shown, specifically, the power unit 2 includes a power head 21, a traction wheel 22, a traction rope 23, and a drive unit 24. The power head 21 is installed at the first end of the entire pipeline. The traction wheel 22 is fixed at the outlet 102 of the high-altitude pipeline support 1 and installed on the structural steel bars at a certain distance from the outlet 102 of the high-altitude pipeline support. The traction rope 23 is wound around the traction wheel 22. One end of the traction rope 23 is fixed to the power head 21, and the other end is connected to the drive unit 24. The drive unit 24 pulls the traction rope 23, thereby driving the entire pipeline to move in the transportation direction. Specifically, the traction wheel 22 is on the same horizontal plane as the pipeline, and the drive unit 24 is located below the traction wheel 22. The traction rope 23 changes direction through the traction wheel 22. In this embodiment, the drive unit 24 is a winch, which has sufficient traction force to smoothly pull the traction rope 23. Specifically, the power head 21 is firmly connected to the first end of the pipeline 41 by bolts to ensure that it will not loosen or fall off during transportation. The traction wheel 22 is made of high-strength alloy material and its surface is specially treated to reduce friction with the traction rope 23 and extend its service life. The traction rope 23 is made of high-strength steel wire rope, which has tensile strength and wear resistance, and can withstand the tension during the overall transportation of the pipeline.

[0039] The beneficial effects of this invention are as follows: the invention is highly safe to operate, allowing workers to work at one point without having to move back and forth, reducing the occurrence of accidents such as falls from heights and lowering safety risks; the device is simple, easy to hoist, and easy to install and transport pipelines at heights; it improves work efficiency and reduces labor costs.
