This results in significant difficulties and high costs associated with pipeline lifting and transportation. Furthermore, safety must be considered when transporting pipelines within confined spaces.

[0003] To improve construction efficiency, reduce construction costs, and ensure construction safety, there is an urgent need for an integrated safety tool capable of effectively lifting and transporting large-diameter pipes in confined spaces. This tool needs to be highly operable, have sufficient load-bearing capacity, and possess high safety performance to adapt to complex and ever-changing construction environments.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0021] An embodiment of this utility model: A tool integrating safe design for loading, unloading, and transporting pipelines in confined spaces includes a square frame formed by multiple interconnected square beams 1. The four corners of the bottom of the square frame are fixed to the tops of four columns 4. A pipe stabilizing safety device mounting frame is installed between the waist positions of the four columns 4. A walking system is provided at the bottom of each of the four columns 4. A lifting lug 13 is provided at the bottom of each of the left and right ends of the square frame, and a hand-operated hoist 14 is installed below the lifting lug 13. A pipe stabilizing safety device 3 is provided at the bottom of each of the left and right ends of the pipe stabilizing safety device mounting frame. The pipe stabilizing safety device 3 includes a steel arc-shaped support plate 33 and a steel arc-shaped cover plate 31 arranged facing each other. The two are connected on each side by four connecting bolts 34 to form a detachable structure. A connecting ear plate 32 is provided on the steel arc-shaped cover plate 31 and connected to the pipe stabilizing safety device mounting frame.

[0022] The square beam 1 includes square beam longitudinal bars 11 and square beam transverse bars 12. The two square beam longitudinal bars 11 and the two square beam transverse bars 12 are connected to form a square frame. Each square beam transverse bar 12 has a lifting lug 13 at the bottom center.

[0023] The mounting frame for the pipe stabilization safety device is formed by connecting multiple H-beams 2. Each H-beam 2 includes two parallel H-beam longitudinal bars 21. Each H-beam longitudinal bar 21 is connected to two columns 4 at the waist. Two H-beam transverse bars 22 are connected between the two H-beam longitudinal bars 21. The H-beam transverse bars 22 are located inside the square beam transverse bars 12 on the same side. A pipe stabilization safety device 3 is provided at the bottom center of each H-beam transverse bar 22. The H-beam transverse bars 22 and the square beam transverse bars 12 on the same side are staggered to avoid interference between the hand chain hoist 14 and the pipe stabilization safety device 3 during operation.

[0024] The walking system is a ground tank 8 installed at the bottom of the column 4, which enables horizontal movement. The ground tank 8 has good load-bearing capacity and durability, high safety performance, and overcomes the disadvantage of frequent inspections in complex construction site environments.

[0025] A stabilizing beam 7 is also connected between the two columns 4 on the front and rear sides below the stabilizing safety device 3. The bottom of each square beam crossbar 12 is connected to the two columns 4 via two diagonal braces A5, forming an isosceles right-angled triangle structure; the bottom of each H-shaped beam longitudinal bar 21 is connected to the two columns 4 via two diagonal braces B6, forming an isosceles right-angled triangle. Through the reinforcement of diagonal beams A5, B6, and the stabilizing beam 7, the structure of this utility model becomes a more stable and robust safety device. The structural design considers the principle of triangle stability, and the use of diagonal beams A5 and B6 makes the overall structural design more compact, and improves stability and safety performance.

[0026] The working principle of this utility model is as follows:

[0027] After determining the location of the pipeline to be transported, the large-diameter pipeline lifting and transport integrated tool is moved to the middle of the pipeline via the ground tank 8. The pipeline is then vertically lifted by the manual chain hoist 14 until it reaches the lower end of the steel arc-shaped cover plate 31. The bottom outer wall of the pipeline is then supported by the steel arc-shaped support plate 33, and the steel arc-shaped cover plate 31 and the steel arc-shaped support plate 33 are tightened and fixed using connecting bolts 34. This reliably secures the pipeline to the pipe stabilizing safety device 3, ensuring stability and safety during pipeline transportation. The horizontal transport of the pipeline is achieved through the movement of the ground tank 8.
