[0044] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0045] In this application, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0046] In addition, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may or may not be the same in type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0047] The technical solution of the present application will be further described below with reference to specific embodiments and drawings.

[0048] Please also refer to Figure 1 and Figure 2The utility model discloses a transport device 1, which is installed at the bottom of an oil and gas tunnel and is used to transport pipelines. The transport device 1 includes a bearing plate 11, anchor bars 12, a track 13 and a bearing assembly 14. The bearing plate 11 is embedded in the bottom wall of the oil and gas tunnel. The bearing plate 11 has an upward bearing surface 111, and the bearing surface 111 is flush with the bottom wall of the oil and gas tunnel. The anchor bars 12 are arranged at the bottom of the oil and gas tunnel and are connected to the bearing plate 11. The track 13 is arranged on the bearing surface 111 and extends along the tunnel direction of the oil and gas tunnel. The bearing assembly 14 is arranged on the track 13 and can move along the extension direction of the track 13. The bearing assembly 14 is used to carry the pipeline.

[0049] The tunnel direction refers to the extension direction of the tunnel.

[0050] In this embodiment, the supporting plate 11 is embedded in the bottom of the oil and gas tunnel, and the supporting surface 111 of the supporting plate 11 is flush with the bottom wall of the oil and gas tunnel, so that the bottom of the oil and gas tunnel can fully restrict the supporting plate 11 in the horizontal direction, so that the supporting plate 11 can be stably installed on the bottom of the oil and gas tunnel, thereby improving the stability of the supporting plate 11 and reducing the possibility of shaking and tilting of the supporting assembly 14 during the transportation of the pipeline, ensuring safety during transportation and preventing the pipeline from falling off.

[0051] In addition, the anchor bar 12 is arranged at the bottom of the oil and gas tunnel and connected to the supporting plate 11, so that the bottom of the oil and gas tunnel can fully restrict the supporting plate 11 in the vertical direction, so that the supporting plate 11 can be further stably installed at the bottom of the oil and gas tunnel, further improving the stability of the supporting plate 11.

[0052] In the existing technology, concrete piers are usually cast, and the unassembled pipelines are hoisted into the oil and gas tunnel for welding by towing the pipeline transport vehicle in conjunction with the gantry. The specific construction process includes the installation of auxiliary facilities such as lighting and ventilation in the tunnel, installation of the drainage system, pipe transportation and layout, casting of piers, pipeline welding, installation of pipelines, and dismantling of temporary facilities.

[0053] In existing technologies, due to the limited space in oil and gas tunnels, installing auxiliary facilities and casting piers within them is limited by site space, reducing construction efficiency. However, in the embodiments of the present application, only anchor bars 12 and bearing plates 11 need to be pre-embedded within the oil and gas tunnel before track 13 is laid on the bearing surface 111 of bearing plates 11. This significantly saves construction space, ensures construction efficiency, and reduces construction costs.

[0054] Secondly, in the embodiment of the present application, there is no need to use devices such as a gantry, which reduces the frequency of equipment transfer and improves construction efficiency.

[0055] Furthermore, due to the poor ventilation and high humidity within oil and gas tunnels, conventional welding techniques prevent the large amount of smoke and dust generated within these tunnels from promptly dispersing outside. This results in high concentrations of suspended particulate matter and other substances in the tunnel air, potentially harming workers. However, in the embodiments of the present application, the pipeline can be welded in an open-air area outside the tunnel, and then transported to the tunnel via transport device 1 after welding is complete. As can be appreciated, due to the high air flow and low humidity in the open-air area outside the tunnel, the smoke and dust generated during welding can be dispersed quickly and not concentrated in a specific area, thus ensuring worker safety.

[0056] See also Figure 2 In some embodiments, a welding hole (not shown in the figure) is provided on the surface of the bearing plate 11 away from the bearing surface 111, and the first end 1211 of the anchor bar 12 is welded into the welding hole by plug welding.

[0057] Among them, plug welding refers to a fusion welding method. Specifically, during welding, filling materials such as copper plates, carbon blocks and iron plates need to be added into the welding holes.

[0058] In this embodiment, the bearing plate 11 is a steel plate, and may also be made of other materials that can be welded, which is not limited here.

[0059] Welding the anchor bars 12 to the load-bearing plate 11 ensures the strength and stability of the connection between the anchor bars 12 and the load-bearing plate 11, preventing loosening of the anchor bars 12 and the load-bearing plate 11 during transportation. Furthermore, the welding holes required for plug welding can be located at any position on the surface of the load-bearing plate 11 facing away from the load-bearing surface 111. Therefore, the layout and number of the anchor bars 12 can be adjusted according to actual needs to meet the transportation requirements of different pipelines.

[0060] In some other embodiments, the first end 1211 of the anchor bar 12 may also be directly welded to the surface of the supporting plate 11 facing away from the supporting surface 111 .

[0061] Please continue reading Figure 2 In some embodiments, the welding hole passes through the bearing surface 111 , and the end surface of the first end 1211 is flush with the bearing surface 111 .

[0062] The welding hole passes through the bearing surface 111 , so that the first end 1211 can be more directly exposed during the welding process, facilitating the welding operation and effectively improving the success rate and efficiency of welding.

[0063] In addition, the end surface of the first end 1211 is flush with the bearing surface 111 , preventing the bearing surface 111 from being convex or concave, thereby ensuring the flatness of the bearing surface 111 .

[0064] In some other embodiments, the height of the end surface of the first end 1211 may also be lower than the height of the supporting surface 111 .

[0065] Please continue reading Figure 2 In some embodiments, the anchor bar 12 includes a first anchor bar segment 121 and a second anchor bar segment 122. The first anchor bar segment 121 is axially perpendicular to the bearing surface 111 and has a first end 1211 and a second end 1212 opposite to each other. The second anchor bar segment 122 is axially perpendicular to the first anchor bar segment 121 and is connected to the second end 1212.

[0066] In this embodiment, the second anchor segment 122 can be connected to the second end 1212 at its end, or at the middle position of the second anchor segment 122, or at any other position of the second anchor segment 122, which is not limited here.

[0067] The axial direction of the first anchor rib segment 121 is perpendicular to the bearing surface 111, and the axial direction of the second anchor rib segment 122 is mutually perpendicular to the axial direction of the first anchor rib segment 121. The vertical force exerted on the second anchor rib segment 122 by the bottom of the oil and gas tunnel can enhance the vertical tension exerted on the bearing plate 11 by the first anchor rib segment 121. At the same time, the mutually perpendicular layout enables the anchor rib 12 to withstand forces from different directions, and enables the anchor rib 12 to better share and balance the forces in various directions, avoiding excessive stress concentration in certain parts, thereby ensuring the stability of the bearing plate 11.

[0068] In some other embodiments, the angle between the axial direction of the second anchor bar segment 122 and the axial direction of the first anchor bar segment 121 may also be less than 90°.

[0069] Please also refer to Figure 1 and Figure 3 In some embodiments, the support assembly 14 includes a base 141, at least two sets of wheels 142, a locking member 143, and a support 144. The at least two sets of wheels 142 are spaced apart from each other on the base 141 along the extension direction of the track 13 and are movable along the extension direction of the track 13. The locking member 143 engages with the outer wall of the pipe to secure the pipe. The support 144 is connected between the base 141 and the locking member 143.

[0070] The support 144 is used to support the pipeline.

[0071] At least two sets of wheel assemblies 142 are spaced apart on the base 141 along the extension direction of the track 13 , so as to balance the center of gravity of the pipeline and prevent the pipeline from tilting during transportation.

[0072] In some other embodiments, the pipe may also be directly fixed to the support 144 .

[0073] Please continue reading Figure 1 and Figure 3 In some embodiments, the engaging member 143 includes a first engaging portion 1431 and a second engaging portion 1432. The first engaging portion 1431 is attached to the upper half of the outer wall of the pipe, and the second engaging portion 1432 is attached to the lower half of the outer wall of the pipe. The two ends of the second engaging portion 1432 are respectively welded to the two ends of the first engaging portion 1431 by full welding.

[0074] Specifically, the first engaging portion 1431 being attached to the upper portion of the exterior of the pipe means that the first engaging portion 1431 is located above the pipe, with its two ends located on opposite sides of the pipe and in the same horizontal plane, and the distance between the two ends of the first engaging portion 1431 is maximized. Similarly, the second engaging portion 1432 being attached to the lower portion of the exterior of the pipe means that the second engaging portion 1432 is located below the pipe, with its two ends located on opposite sides of the pipe and in the same horizontal plane, and the distance between the two ends of the second engaging portion 1432 is maximized. This structure facilitates welding of the two ends of the first engaging portion 1431 and the two ends of the second engaging portion 1432, thereby improving welding efficiency.

[0075] In some other embodiments, both ends of the first engaging portion 1431 may extend to the lower half of the outer wall of the pipe.

[0076] See also Figure 3 In some more specific embodiments, the size of the second engaging portion 1432 in the axial direction of the pipe gradually increases from both ends of the second engaging portion 1432 to the middle position of the second engaging portion 1432.

[0077] The middle position of the second engaging portion 1432 refers to a position that is equidistant from both ends of the second engaging portion 1432 .

[0078] The axial dimension of the second engaging portion 1432 in the pipe gradually increases from both ends of the second engaging portion 1432 toward the middle of the second engaging portion 1432. This increases the contact area between the second engaging portion 1432 and the pipe, thereby dispersing the pressure exerted by the pipe on the second engaging portion 1432 and protecting the second engaging portion 1432. Furthermore, increasing the contact area between the second engaging portion 1432 and the pipe increases friction between the second engaging portion 1432 and the pipe, thereby enhancing the fixing effect on the pipe.

[0079] In some other more specific implementations, the size of the second engaging portion 1432 in the axial direction of the pipe may also be the same everywhere.

[0080] Please also refer to Figure 1 and Figure 3 In some embodiments, the support 144 includes a support portion 1441 and at least two reinforcement portions 1442. The support portion 1441 is connected between the base 141 and the engaging member 143 to support the pipe. The at least two reinforcement portions 1442 are respectively connected to the side walls on both sides of the support portion 1441.

[0081] Reinforcement parts 1442 are provided on both sides of the support part 1441. Under the premise of preventing the weight of the support 144 from being too heavy, the support 144 can enhance the supporting capacity of the pipeline. At the same time, the support 144 can also enhance the horizontal limiting effect of the pipeline to ensure the safety of the transportation process.

[0082] In some other embodiments, the size of the support 144 may be increased in the horizontal direction.

[0083] See also Figure 1 In some more specific embodiments, the side wall of the support portion 1441 is parallel to the vertical direction; the reinforcing portion 1442 has a first surface 1442a, the first surface 1442a is away from the side wall of the support portion 1441, and is inclined relative to the side wall of the support portion 1441, and the distance between the first surface 1442a and the side wall of the support portion 1441 gradually increases in the vertical upward direction.

[0084] In this embodiment, the first surface 1442a of the reinforcing portion 1442 is inclined relative to the side wall of the supporting portion 1441, and the distance between the first surface 1442a and the side wall of the supporting portion 1441 gradually increases in the vertical upward direction, which can further enhance the restraining effect of the support 144 on the pipeline in the horizontal direction.

[0085] In some other more specific implementations, the first surface 1442 a may also be parallel to the sidewall of the support portion 1441 .

[0086] Please continue reading Figure 1 In some more specific embodiments, the reinforcement portion 1442 further has a second surface 1442b and a third surface 1442c, the second surface 1442b is attached to the locking member 143, the third surface 1442c is connected between the first surface 1442a and the second surface 1442b, the axis of the pipe is located on the extension plane of the third surface 1442c, and the angle between the third surfaces 1442c of the two reinforcement portions 1442 located on both sides of the support portion 1441 is 90°.

[0087] Among them, the axis of the pipeline is located on the extension plane of the third surface 1442c, and the angle between the third surfaces 1442c of the two reinforcement parts 1442 located on both sides of the support part 1441 is 90°, which not only enhances the overall structural stability of the support 144, but also can effectively disperse the pressure and load from the pipeline, reduce the occurrence of stress concentration, and improve the durability and service life of the support 144.

[0088] In some other more specific embodiments, the angle between the third surfaces 1442 c of the two reinforcing portions 1442 located on both sides of the supporting portion 1441 may also be greater than 90°.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
