Description

Technical Field

[0001] This utility model relates to the field of petrochemical pipeline transportation technology; specifically, this utility model relates to a prefabricated long-distance pipeline transportation tool for pipe racks. Background Technology

[0002] In some petrochemical construction projects, supporting pipeline corridors are indispensable, especially for pipeline installation and transportation in existing pipeline corridors, which present numerous challenges. For safety reasons, existing pipeline corridors often have high standards and requirements for construction operations, with pipeline welding being a significant factor. This necessitates the pre-installation of five-sided protective barriers, operates in extremely limited space, and carries a high risk of open flame work in operational corridors. To minimize work above the pipeline corridor, prefabrication and welding are performed on the ground. However, the prefabricated pipelines are quite long, and due to limitations in truck height and cab size, ordinary 13m flatbed trucks cannot transport them due to the excessive length. Furthermore, road and space constraints prevent even longer flatbed trucks from turning. Considering construction costs, this application provides a prefabricated long-distance pipeline transportation tool for pipeline corridors. Utility Model Content

The second-layer crossbeam connects the same-side ends of the two second-layer main beams. The secondary reinforcing beams are equidistantly arranged between the two second-layer crossbeams, and the two ends of the second-layer sub-beam are respectively connected to the two second-layer main beams.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1 to 4 As shown, a typical embodiment of this utility model provides a prefabricated long-distance pipeline transportation tool for utility tunnels, including a first-layer base, a second-layer base, a column 2-1, and a front-mounted lifting structure. The bottom of the first-layer base is supported on the frame of a pipeline transportation trolley, forming the cargo compartment of the pipeline transportation vehicle. The second-layer base is fixedly installed above the first-layer base via the column 2-1 for placing the pipeline. The front-mounted lifting structure is located at the front end of the top of the second-layer base to raise the front half of the pipeline to avoid obstructing the vehicle's front end.

[0026] After applying this embodiment, when transporting long-distance prefabricated pipelines on the ground, the combination of the two-layer base and the front-mounted heightening structure allows the pipeline to be placed more stably on the two-layer base, and ensures that the height of the front half of the pipeline is greater than that of the truck head, so that the front end of the pipeline can extend forward from the top of the truck head, thereby shortening the horizontal projection distance, avoiding the limitations of the truck bed height and the truck head, and enabling the transport vehicle to make smooth turns in restricted road areas during pipeline transportation, thus realizing the effective transportation operation of prefabricated long-distance pipelines in the pipe gallery.

[0027] In this embodiment, the base includes two parallel longitudinal main beams 1-1, a transverse main beam 1-2 connecting the same side ends of the two longitudinal main beams 1-1, an intermediate main beam 1-3 connecting the two longitudinal main beams 1-1 at both ends and equidistantly positioned between the two transverse main beams 1-2, and intermediate secondary beams 1-4 connecting the two longitudinal main beams 1-1 at both ends and staggered with the intermediate main beams 1-3. The longitudinal main beams 1-1, transverse main beams 1-2, and intermediate main beams 1-3 are all H-beams, the intermediate secondary beams 1-4 are channel steel, and stiffening ribs 1-5 are fixedly installed inside the longitudinal main beams 1-1. All connections between the various parts of the base can be fixed by welding.

[0028] In a relatively specific embodiment, the longitudinal main beam 1-1 is made of 150*150 H-beams, the transverse main beam 1-2 is made of 150*150 H-beams, the intermediate main beam 1-3 is made of 150*150 H-beams, and the stiffening ribs 1-5 are welded from t=12mm steel plates. The column 2-1 has a specification of Φ114*6.3.

[0029] In this embodiment, the second-layer base includes two parallel second-layer main beams 3-1, a second-layer crossbeam 3-3, and a second-layer sub-beam 3-4. One second-layer main beam 3-1 is positioned above each of the two longitudinal main beams 1-1, and the second-layer main beam 3-1 is fixedly connected to the column 2-1. The second-layer crossbeam 3-3 connects the same-side ends of the two second-layer main beams 3-1. Secondary reinforcing beams are equidistantly positioned between the two second-layer crossbeams 3-3, and both ends of the second-layer sub-beam 3-4 are connected to the two second-layer main beams 3-1 respectively. Both the second-layer main beams 3-1 and the second-layer crossbeams 3-3 are H-beams, and the second-layer sub-beam 3-4 is a channel steel.

[0030] In a relatively specific embodiment, the second-floor main beam 3-1 is made of 100*100 H-beams, and the second-floor crossbeam 3-3 is also made of 100*100 H-beams. A lifting lug 3-2, made of t=16mm steel plate, is fixedly installed on the second-floor main beam 3-1. Specifically, the second-floor main beam 3-1 and the second-floor crossbeam 3-3 are first welded to the column 2-1, then the second-floor beam 3-4 is welded to the second-floor main beam 3-1, and finally the lifting lug 3-2 is welded to the second-floor main beam 3-1.

[0031] Among them, multiple columns 2-1 are equidistantly arranged on the top of the longitudinal main beam 1-1, and the second-floor main beam 3-1 includes multiple beam parts, and in the length direction of the longitudinal main beam 1-1, the beam parts fix two adjacent columns 2-1.

[0032] In this embodiment, the top height of column 2-1 is greater than the height of the front-mounted heightening structure, and along the length of the longitudinal main beam 1-1, the top of column 2-1 is connected to a lifeline claw 2-3. Specifically, the lifeline claw 2-3 can be a Φ12mm steel wire rope. A pull ring 2-2 is fixedly installed on the top of the side surface of column 2-1, the lifeline claw 2-3 passes through the pull ring 2-2, and both ends of the lifeline claw 2-3 are fixed by the lifeline claw.

[0033] During implementation, first weld the column 2-1 to the longitudinal main beam 1-1, then fix the finished pull ring 2-2 to the column 2-1, and then pull the lifeline cat claw 2-3 to the column 2-1, fixing both ends with the lifeline cat claw.

The heightening short beam 4-1 is fixedly installed at the front end of the top of the second-layer base, and the heightening pad is fixed on the top of the heightening short beam 4-1.

The heightened short beam 4-1 is made of 100*100 H-beams, the heightening pads are made of square timber, and wire holes 4-5 are opened on the heightened short beam. Wires 4-4 pass through the wire holes 4-5 and bind and fix the square timber to the top of the heightened short beam 4-1.

[0036] Rubber pads 4-2 are installed on the top of the second-layer base, the top of the heightened short beam 4-1, and the top of the heightened pad block.

[0037] During implementation, the heightening short beam 4-1 is welded to the column 2-1 and the second-layer crossbeam 3-3. The timber 4-3 is then fixed to the heightening short beam 4-1 using wire 4-4. To protect the sharp edges of the wire 4-4, rubber pads 4-2 are installed on both the timber 4-3 and the heightening short beam 4-1. The entire second-layer base is welded to the column 2-1, and rubber pads 4-2 are used to secure and protect the entire second-layer crossbeam 3-3 and the second-layer beam 3-4, increasing friction and protecting the pipe surface paint from damage.
