Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a pipeline transmission device and a pipeline transmission system. Background Art

[0002] In chemical projects, since the process pipelines on the entire pipeline corridor are too long, they are generally composed of multiple shorter pipeline sections that are installed and welded in sequence end to end. During the pipeline corridor installation process, the installation and welding positions of the pipelines need to be determined in advance. The pipelines are transported to the welding positions by cranes, and then the workers weld the pipelines. After the workers complete the welding, the crane transports another section of the pipeline to the corresponding welding position, and the workers move to the corresponding welding positions simultaneously for welding.

[0003] The above pipeline welding process is relatively complicated, and because the crane needs to constantly change positions to hoist the pipeline section by section during the pipeline installation process, the workers also need to change the welding position, resulting in low efficiency of process pipeline installation. Therefore, it is necessary to invent a pipeline conveying device to improve the efficiency of process pipeline installation, thereby shortening the pipeline installation period and saving labor and machinery costs.

[0025] The utility model provides a pipeline conveying device and a pipeline conveying system. Figure 1 to Figure 2 The utility model provides a specific embodiment of a pipeline transmission device.

[0026] like Figure 1 As shown, an embodiment of the utility model provides a pipeline conveying device 100, including a machine base 1, a fixing component 2 and a conveying component 3, wherein the fixing component 2 includes two fixing parts 21 arranged relatively to the machine base 1 in the x direction, the conveying component 3 is connected between the two fixing parts 21, and the conveying component 3 includes a rotating part 311 for carrying the pipeline, and the rotating part 311 is rotatably arranged so that the pipeline has a movable stroke in the y direction.

[0027] It should be noted that the two fixing parts 21 may also be arranged relative to each other in the y direction. In this case, the rotating part 311 rotates so that the pipeline has a movable stroke in the x direction. It is only necessary to ensure that the x direction is arranged perpendicular to the y direction.

[0028] Specifically, the connection method between the components in the pipeline conveying device 100 can be welding or other fixing methods known to those skilled in the art.

[0029] In the utility model, two fixing parts 21 are arranged relatively in the x direction, and the conveying component 3 is connected between the two fixing parts 21. The conveying component 3 includes the rotating part 311 for carrying the pipeline. The rotating part 311 is rotatably arranged. Since the conveying component 3 is arranged along the x direction, that is, the rotating part 311 extends along the x direction, when the rotating part 311 rotates, the pipeline has an active stroke in the y direction. With this arrangement, the crane places the pipeline to be welded on the pipeline conveying device 100, and the workers weld the pipeline. When the workers finish welding, the welded pipeline moves in the y direction to be separated from the current pipeline conveying device 100. At the same time, the crane places another section of the pipeline on the pipeline conveying device 100, and the workers continue to weld. Compared with the existing pipeline welding process, the crane and the workers do not need to move, and there is no need to determine the welding position of each section of the pipeline in advance, which greatly improves the installation efficiency of the process pipeline of the entire pipeline corridor, thereby shortening the pipeline installation period and saving labor and machinery costs.

[0030] Specifically, the pipeline conveying device 100 is arranged on the crossbeam of the H-shaped steel of the pipeline gallery, and the machine base 1 is fixed to the crossbeam by using U-shaped limit cards or wire rope binding to prevent the pipeline conveying device 100 from moving or tipping over during the conveying process of the pipeline.

[0031] It should be noted that the upper end surfaces of the two fixing parts 21 are higher than the conveying assembly 3. Since the pipeline moves on the conveying assembly 3, this arrangement is to prevent the pipeline from detaching from the pipeline conveying device 100 during the movement and injuring the welding workers.

[0032] Since the pipes to be welded are usually heavy during the actual installation of the process pipes, a single conveying assembly 3 may not be able to carry the pipes for a long time. Therefore, in some embodiments, Figure 1 As shown, the conveying assembly 3 includes two conveying structures 31 and a connecting portion 32 provided on the machine base 1. One end of the two conveying structures 31 is connected to the connecting portion 32, and the other end is respectively connected to the corresponding fixing portion 21. By providing two conveying structures 31 to share the pressure of the pipeline, it is prevented that a single conveying structure 31 is damaged after long-term use. At the same time, the connecting portion 32 provided on the machine base 1 can also help share the pressure on the two fixing portions 21.

[0033] Furthermore, when two conveying structures 31 are provided, the pipeline only contacts one corner of the ends of the two conveying structures 31. Since the forces on the two ends of the same conveying structure 31 are inconsistent, the conveying structure 31 may be deformed and damaged after long-term use. Therefore, in some embodiments, Figure 1As shown, the conveying structure 31 is arranged to slope downward from one end connected to the fixed part 21 towards the direction close to the connecting part 32. With such an arrangement, the pipeline can be in contact with the end face of the conveying structure 31, and the generated pressure can be distributed over the entire conveying structure 31, so as to extend the service life of the conveying structure 31. At the same time, the two obliquely arranged conveying structures 31 enable the pipeline to always be between the two conveying structures 31 under the influence of gravity, thereby restricting the movement of the pipeline in the x direction and making the welding effect of the pipeline better during welding.

[0034] Furthermore, although the obliquely arranged conveying structure 31 can restrict the movement of the pipeline in the x direction, it also limits the size of the pipeline that can be conveyed. In order to make the pipeline conveying device 100 adapt to pipelines of more sizes, in some embodiments, the included angle between the conveying structure 31 and the horizontal direction is r, where 0° < r ≤ 45°. The smaller the included angle between the conveying structure 31 and the horizontal direction, the more sizes of pipelines can be adapted, but at the same time, the effect of the conveying structure 31 in distributing pressure is worse. Therefore, the included angle between the conveying structure 31 and the horizontal direction can be determined according to the actual size of the conveyed pipeline.

[0035] In some embodiments, as Figure 1 shown, the conveying structure 31 includes a rotating part 311, a supporting part 312 passing through the rotating part 311, and a bearing 313 arranged between the supporting part 312 and the rotating part 311. One end of the supporting part 312 is connected to the connecting part 32, and the other end is connected to the fixed part 21. The rotating part 311 is rotatably arranged along the axis extending in the length direction of the supporting part 312. The inner ring of the bearing 313 is connected to the supporting part 312, and the outer ring is connected to the rotating part 311. Since the outer ring of the bearing 313 rotates relative to the inner ring, the rotating part 311 rotates relative to the supporting part 312. At this time, the axial direction of the rotating part 311 is consistent with the length direction of the supporting part 312.

[0036] It should be noted that the bearing 313 can be a ball bearing 313, a needle bearing 313, including but not limited to other types of bearings 313 well-known to those skilled in the art.

[0037] Further, when a worker welds the pipeline, it is necessary to ensure that the pipeline is in a static state. The obliquely arranged conveying structure 31 has restricted the movement of the pipeline in the x direction. In order to restrict the movement of the pipeline in the y direction, in some embodiments, as Figure 1As shown, the conveying structure 31 further includes a limiting portion 314 disposed on the supporting portion 312, the limiting portion 314 has a movable stroke in the length direction of the supporting portion 312, and the end of the limiting portion 314 close to the bearing 313 can extend into the bearing 313 to limit the rotation of the rotating portion 311. In this way, by limiting the rotation of the rotating portion 311, the movement of the pipeline in the y direction can be limited. At this time, the pipeline is in a stationary state, the worker can weld the pipeline more effectively, and it can also prevent the pipeline from moving and injuring the operator.

[0038] It should be noted that the method of limiting the rotation of the rotating part 311 is not limited to limiting the rotation of the rotating part 311 by interfering with the bearing 313 through the limiting part 314. The rotation of the rotating part 311 can also be limited by providing a bearing 313 with a rotation limiting function.

[0039] Specifically, the support portion 312 is provided with a movable groove along its length direction, and the transmission structure 31 further includes a movable portion 315, the movable portion 315 can move in the movable groove, and the movable portion 315 is connected to the limiting portion 314, so that the limiting portion 314 can move in the length direction of the support portion 312. In this configuration, the movable portion 315 moves in the movable groove to drive the limiting portion 314 to move in the length direction of the support portion 312, so that the limiting portion 314 can extend into the bearing 313, interfere with the movement of the ball or needle in the bearing 313, thereby limiting the rotation of the outer ring of the bearing 313, and finally limiting the rotation of the rotating portion 311.

[0040] When a bearing 313 is provided, in order to ensure that the pressure on the rotating part 311 can be better transmitted to the supporting part 312, the bearing 313 needs to be provided at the force points of the pipe and the rotating part 311. However, pipes of different sizes have different force points on the rotating part 311. Therefore, in some embodiments, as Figure 1 As shown, at least two bearings 313 are provided, and the two bearings 313 are respectively provided at both ends of the rotating part 311. Such a configuration allows the pressure on the rotating part 311 to be more evenly transmitted to the supporting part 312, thereby preventing the rotating part 311 from being deformed due to different pressures at different positions. The more the number of bearings 313, the better, and the specific number is determined in combination with the actual cost.

[0041] In some embodiments, Figure 1As shown, the connecting portion 32 includes two connecting members 321 connected to each other, and the free ends of the two connecting members 321 are arranged to be tilted downward in a direction away from each other. In this way, the two connecting members 321 and the base 1 form a triangle. Due to the stability of the triangle, the connecting portion 32 can better transfer the pressure on the conveying structure 31 to the base 1, and is not easily deformed.

[0042] In some embodiments, Figure 2 As shown, the fixing portion 21 includes a first fixing member 211 and a second fixing member 212 connected to each other, one of the first fixing member 211 and the second fixing member 212 extends along the x direction and the other extends along the y direction, and the second fixing member 212 is connected to the transmission component 3. In this way, the first fixing member 211 and the second fixing member 212 can support each other, and when the second fixing member 212 is subjected to the pressure transmitted by the transmission component 3, the first fixing member 211 can share the pressure and transmit the pressure to the base 1.

[0043] Specifically, the connecting portion 32 and the fixing portion 21 can both be made of angle steel on the construction site, which is not only simple to manufacture but also extremely low in cost, and is easy to replace when a component is damaged.

[0044] In addition, the utility model also provides a pipeline conveying system, which includes a plurality of pipeline conveying devices 100 and a driving unit as described above, wherein the pipeline conveying device 100 includes a machine base 1, a fixing component 2 and a conveying component 3, wherein the fixing component 2 includes two fixing parts 21 relatively arranged on the machine base 1 in the x direction, the conveying component 3 is connected between the two fixing parts 21, and the conveying component 3 includes a rotating part 311 for carrying the pipeline, the rotating part 311 is rotatably arranged so that the pipeline has a movable stroke in the y direction, and the driving unit is used to drive the pipeline to move in the y direction.

[0045] It should be noted that, in actual use, a plurality of the pipeline conveying devices 100 are provided, and the distance between each of the pipeline conveying devices 100 is less than the length of the pipeline to be welded.

[0046] Specifically, the driving part can be a winch. When the worker completes welding, the winch directly pulls the pipe to move in the y direction and detaches from the current pipe conveying device 100 to the next pipe conveying device 100. The driving part can also be connected to the rotating part 311, and drives the rotating part 311 to rotate during operation to drive the pipe to move in the y direction.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
