Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipeline construction, in particular to a natural gas transmission pipeline supporting structure. Background Art

[0002] A natural gas pipeline refers to a pipeline that transports natural gas from the extraction site or processing plant to the urban gas distribution center or industrial enterprise users. It is also called a gas transmission pipeline. Using a natural gas pipeline to transport natural gas is the only way to transport natural gas in large quantities on land. Natural gas pipelines account for about half of the world's total pipeline length.

[0003] Since the natural gas extraction site is too far away from the gas distribution center, the assembled natural gas pipeline will be laid on various rugged mountains. However, since the natural gas pipeline is composed of multiple sections, the existing support structure cannot effectively control the height of the adjustment during the adjustment process. It is very easy to adjust it too high or too low each time. Once the position and height of the support frame fixed to the ground deviate, the pipelines cannot be assembled, and the support frame needs to be fixed to the ground again, which is not only time-consuming and labor-intensive, but also reduces the efficiency of the installation, resulting in the need for repeated debugging each time, which reduces work efficiency and seriously affects the progress of the project.

DETAILED DESCRIPTION

[0018] Please refer to the attached Figure 1-Figure 3 Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0019] The utility model proposes a natural gas transmission pipeline support structure. Before use, a pair of card plates 1 are at the farthest relative distance, a group of gripping nails 7 are located at a position higher than the universal wheel, and the lifting plate 4 is at the lowest position. When using the device, after pushing the device to a point on the set route for laying the pipeline, after adjusting the angle and position of a group of card plates 1, first rotate a turntable 15, and the turntable 15 drives the corresponding lead screw 6 to rotate, and the lead screw 6 drives the corresponding gripping nail 7 to slide downward. When the lower side of the gripping nail 7 is in contact with the ground, stop rotating a turntable 15, adjust the U-shaped gripping nail 7 to a suitable gripping angle according to the terrain, and continue to rotate a turntable 15, and a lead screw The corresponding gripping nails 7 are driven by the screws 6 to be inserted into the ground. After one gripping nail 7 is driven into the ground to a suitable depth, the remaining turntables 15 are rotated in sequence. By adjusting the gripping depth of a group of gripping nails 7, the vehicle plate of the vehicle body is leveled (for example, a leveling method is: after all the gripping nails 7 on one side are driven into the ground, the turntable 15 is continuously rotated. Under the action of the reaction force of the gripping nails 7, one end of the vehicle plate slides upward along a pair of lead screws 6, so that the universal wheel on the corresponding side is separated from the ground, while the gripping nails 7 on the other side only need to be driven into the ground. In short, the gripping nails 7 at the highest point are driven into the ground first, and the descending depths of the gripping nails 7 at other lower surfaces and the corresponding lead screws 6 are adjusted to achieve the purpose of leveling the vehicle plate). It is suitable for supporting pipelines on various rugged mountains to avoid the pipelines being in a tilted state and unable to be assembled during pipeline laying, and the gripping nails 7 can fix the device. After adjusting the vehicle plate to a horizontal state, start the motor 14, the motor 14 drives the bevel gear 10 to rotate, the bevel gear 10 drives the bevel gear 2 8 meshing therewith to rotate, the bevel gear 2 8 drives the sleeve 9 to rotate, the sleeve 9 drives the lead screw 2 12 to slide upward, the lead screw 2 12 pushes the lifting plate 14 to slide upward, the lifting plate 4 drives a group of rectangular tubes 5 to slide upward along the corresponding rectangular rods 11, and the height of a pair of card plates 1 on the lifting plate 4 is adjusted according to the height of the required pipeline installation. After the height of the pair of card plates 1 is adjusted, close the lifting plate 4. The motor 14 first adjusts the lifting plates 4 of a group of supporting devices to a uniform height according to the laying route and the road section. The adjustment method is the same and will not be repeated here, which is convenient for the subsequent laying of the natural gas pipeline. When the height of the supporting device is adjusted for laying the pipeline, the corresponding hexagonal end cap 13 is rotated by a hexagonal wrench, and the hexagonal end cap 13 drives the screw three 2 to rotate, and the screw three 2 drives a pair of sliders 3 to slide along the groove in the direction of approaching each other, and the pair of sliders 3 drives the corresponding card plates 1 to slide in the direction of approaching each other. When the right-angle grooves on the opposite side of a pair of card plates 1 are tightly fitted to the outside of the pipeline, stop rotating the hexagonal end cap 13, and use the pair of card plates 1 to fix and support the pipeline of the corresponding section.
