Description

Technical Field

[0001] The invention belongs to the field of pipeline construction, and in particular relates to a pipeline transportation device. Background Art

[0002] When adding or replacing pipelines in some narrow and closed trenches for transporting radioactive materials, due to site restrictions, the rigid pipe sections cannot be lowered into the trenches through reserved holes such as manholes. They need to be delivered into the trenches through special straight through-the-wall holes, and then manually carried to the installation location, and then welded and assembled at the installation location. Affected by the trench construction structure and the radioactive space dose rate in the trench, the transportation and welding of the pipelines to be transported in the narrow trenches are difficult, and the work intensity is high. The poor air flow in the construction environment during welding makes welding difficult. The long-term stay of personnel can easily cause construction personnel to be exposed to unnecessary radiation, which does not meet the principle of optimal management of radiation protection.

[0037] Example 1

[0038] like Figure 1-4 As shown, a pipeline transportation device includes: a card slot 4, a pipeline to be transported 5,

[0039] An angle adjustment device 2; at least two of the angle adjustment devices 2 are provided and are symmetrically distributed with the pipeline 5 to be transported as the central axis; a ball component 1, at least two first ends of the ball components 1 are connected to the angle adjustment device 2 through the notch 21; a fixing member 3, the fixing member 3 is used to fix the angle adjustment device 2 in the slot 4.

[0040] Specifically, the present application provides the angle adjustment device 2, which can be adjusted according to the pipeline 5 to be transported.

[0041] The size can be flexibly customized to suit pipes of various outer diameters, thus improving the flexibility and adaptability of the construction. In addition, the angle adjustment device 2 is symmetrically distributed with the pipe 5 to be transported as the central axis, thus ensuring the stability and balance of the pipe when it is transported between pipe supports, and reducing the risk of stress concentration and weld damage that may be caused by pipe transportation.

[0042] In this embodiment, the angle adjustment device 2 is fixed in the slot 4 by the fixing member 3, thereby ensuring the stability of the entire pipeline transportation device during operation. A notch 21 is provided at the center of the angle adjustment device 2 for connecting with the ball component 1.

[0043] 1 and the angle adjustment device 2 are connected to the notch 21 through the protruding shaft of the second limit plate 16, providing additional support and buffering for the pipeline to be transported 5. During the transportation of the pipeline to be transported, these ball components 1 can reduce the friction between the pipeline to be transported and the pipeline transportation device, reduce wear and noise, and also help to maintain the stability of the transportation of the pipeline to be transported.

[0044] Since the present invention connects the clamping slot 4 and the angle adjustment device 2 via the fixing member 3, the entire pipeline transportation device can be more easily disassembled and assembled when maintenance and overhaul are required, which not only improves maintenance efficiency but also reduces maintenance costs.

[0045] In a feasible implementation manner, along the direction from the at least two angle adjustment devices 2 to the axis of the pipeline 5 to be transported, the height of the angle adjustment devices 2 gradually decreases from the end away from the axis of the pipeline 5 to the end close to the axis of the pipeline 5 to be transported, forming a slope. After the at least two angle adjustment devices 2 are assembled with the ball component 1, the central axes of the symmetrically distributed ball components 1 form a V shape.

[0046] Specifically, the sloped angle adjustment device 2 can be customized according to the pipeline 5 to be transported to adapt to the transportation of pipelines with different outer diameters; the arrangement of the ball components 1 on the V-shaped central axis enables the ball components 1 on both sides to support the pipeline 5 to be transported at the same time and provide a stable guiding effect when the pipeline 5 to be transported moves. This stable support structure helps to prevent the pipeline to be transported from shifting or shaking during transportation. In addition, by adjusting the "V" angle of the angle adjustment device on both sides, it can adapt to the needs of pipelines to be transported with different diameters. This flexibility enables the transportation device to be applied to pipelines to be transported of various specifications and installation conditions. The V-shaped arrangement of the ball components 1 not only improves the support stability, but also optimizes the space utilization around the pipeline to be transported.

[0047] In a feasible implementation manner, the second ends of at least two of the rolling ball components 1 are in contact and connected with the outer peripheral wall of the pipeline 5 to be transported to achieve support and transportation of the pipeline 5 to be transported.

[0048] In this embodiment, the contact between the ball component 1 and the outer wall of the pipeline 5 to be transported is achieved by rolling, which can reduce the friction resistance during transportation. Compared with sliding friction, rolling friction has less resistance, so it can significantly improve the transportation efficiency of the pipeline 5 to be transported. Specifically, the rolling friction between the ball component 1 and the pipeline 5 to be transported reduces the direct contact area and frequency between the pipeline 5 to be transported and the transport device, thereby reducing the degree of wear of the pipeline to be transported.

[0049] Specifically, the design of at least two rolling ball components 1 in the present application provides multi-point support for the pipeline to be transported, enhances the stability of the pipeline to be transported during transportation, and helps prevent the pipeline 5 to be transported from being offset or tipped over due to vibration or impact during transportation.

[0050] In a feasible embodiment, the ball component 1 includes: a first limit plate 11, a ball 13, a sleeve 14, and a second limit plate 16 from the conveying pipeline 5 to the angle adjustment device 2; the ball 13 is partially sleeved in the sleeve 14; the sleeve 14 is a hollow tubular structure, and the diameter of the sleeve 14 is larger than the diameter of the ball 13, and is used to accommodate and support the ball 13.

[0051] In this embodiment, the rolling ball 13 is made of polytetrafluoroethylene. The rolling ball 13 is in point contact with the outer peripheral wall of the pipeline 5 to be transported. After the pipeline 5 to be transported is placed on the pipeline transportation device, a supporting force is applied to the pipeline 5 to be transported axially. The pipeline 5 to be transported and the rolling ball 13 are in point-line sliding motion, and the friction resistance is small. At the same time, the polytetrafluoroethylene ball in the rolling ball component is in a rolling shape in the sleeve, which further reduces the sliding resistance of the pipeline to be transported, can realize easy transportation of the pipeline to be transported, and can effectively realize fixed support of the pipeline to be transported.

[0052] In this embodiment, a plurality of groups of latch teeth 41 are symmetrically arranged at both ends of the slot 4 along the axial direction of the pipeline 5 to be transported, and the angle adjustment device 2 is connected to the slot 4 through the fixing member 3 passing through the latch teeth 41 .

[0053] In a feasible implementation manner, the fixing member 3 includes a buckling device for inserting into and / or buckling onto the buckling teeth 41 at both ends of the buckling slot.

[0054] The fixing member 3 of the present application is configured as a buckle device that can be quickly and accurately inserted into the teeth at both ends of the slot 4, so as to fix the connection between the angle adjustment device 2 and the slot 4, and to adjust the angle adjustment device 2 arranged along the x direction on the slot 4. Compared with traditional fixing methods such as bolts and nuts, the buckle device can be installed without the use of additional tools, reducing the requirements for the skills of the installer. In addition, the tight engagement between the buckle device and the teeth ensures a stable connection between the angle adjustment device and the slot, which helps to prevent loosening or falling off due to factors such as vibration and impact during the transportation of the pipeline to be transported. When the fixing member needs to be replaced or repaired, it can be easily removed from the slot, reducing the difficulty and time of maintenance work. Since the disassembly process is simple and does not cause damage to the slot, fixing member and angle adjustment device, the service life of these components can be extended and the maintenance cost can be reduced.

[0055] In a feasible implementation manner, the bottom of the angle adjustment device 2 is provided with a limiting slot 22 adapted to the latching tooth 41;

[0056] The pipeline transportation device is provided with a fixing member 3 , and the angle adjustment device 2 is fixed inside the slot 4 by passing the fixing member 3 through the limiting slot 22 and the latching teeth 41 .

[0057] In a feasible embodiment, when the pipeline transport device is provided with at least two fixing members 3, the fixing members 3 are respectively arranged on both sides of the slot 4 which is perpendicular to the extension direction of the pipeline 5 to be transported, and at least two of the fixing members 3 respectively pass through the teeth 41 on both sides of the slot 4, and the angle adjustment device 2 is fixed inside the slot 4 by mechanical engagement.

[0058] In this embodiment, at least two fixing members 3 are provided on both sides of the slot 4, respectively, so as to form a double fixation for the angle adjustment device 2 and an adjustment and fixation of the angle adjustment device 2 between different teeth on the slot 4, which significantly improves the stability of the angle adjustment device and the slot. The two fixing members 3 are distributed on both sides of the slot, so that the fixing force can be more evenly distributed on the angle adjustment device, avoiding deformation or damage caused by uneven force.

[0059] In a feasible implementation manner, the first limiting plate 11 is arranged on the rolling ball component

[0060] 1 is close to one end of the pipeline 5 to be transported, and is used to limit the movement of the rolling ball 13 toward the pipeline 5 to be transported;

[0061] The second limiting plate 16 is arranged at the end of the ball component 1 away from the pipeline 5 to be transported, and is used to limit the movement of the ball 13 toward the angle adjustment device 2 and to support the ball 13. At the same time, the second limiting plate 16 is provided with a protruding shaft for cooperating and connecting with the notch 21 of the angle adjustment device 2.

[0062] In a feasible embodiment, a first weld 12 matching the ball 13 is arranged between the first limiting plate 11 and the ball 13; a second weld 15 is arranged between the sleeve 14 and the second limiting plate 16, and the first weld 12 and the second weld 15 are used to limit the ball 13 in the cavity formed by the first limiting plate 11, the sleeve 14, and the second limiting plate 16.

[0063] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention.
