Description

Technical Field

[0001] The present invention relates to the technical field of pipeline transportation, and particularly to a horizontal transportation device for lifting pipeline installation in an integrated pipe gallery. Background Technique

[0002] When installing pipelines with height requirements in the pipe gallery, it is usually necessary to use a horizontal transportation device to complete the transportation of the pipelines. The welded pipelines are sequentially transported to the upper end of the pipeline support, and the support is used to pre-support the pipelines; to reduce the installation difficulty, and when the pipelines are completely laid, the adjustment unit on the pipeline support is used to achieve stable support for the pipelines.

[0003] However, since the pipeline supports are pre-fixed to the gallery wall, as shown in the attached Figure 1 specification, there is an installation height difference h1 between the supports, which will cause the end of the horizontally moving pipeline to impact the support. Moreover, as the length and mass of the pipeline increase through welding, this impact will become more intense. When the support cannot transport the pipeline above it through its own deformation, the forced displacement of the pipeline will cause the support to break away from the gallery wall; the free end of the pipeline without support will become a longer cantilever beam, generating more deformation and causing a more intense impact on the subsequent supports. On the one hand, it affects the transportation efficiency of the pipeline, and on the other hand, frequent impacts will cause uncertain deformation of the free end of the pipeline.

[0004] Refer to the Chinese utility model patent with the application number CN201621194507.6; in the means described therein, the core idea is to achieve the transportation inside the pipe gallery through a number of horizontally distributed transportation devices at equal intervals. Essentially, it is a relay transportation method, which can more effectively solve the transfer problem. However, before transportation, each horizontal transportation unit needs to be calibrated with each other; it takes a long time and is difficult. Secondly, multiple horizontal transportation devices also mean higher transfer costs. Summary of the Invention

[0020] Reference Figure 6, the transport device is transported to the pipe joint inside the integrated pipe gallery by means of a crane and other equipment; the roller at the bottom end of the base 1 is locked, the base 1 is relatively fixed to the ground of the integrated pipe gallery, and the transport device remains stable; the pipes in the pipe gallery are installed and spliced ​​from top to bottom in sequence; the electric telescopic element 2 drives the support frame 3 to move upward until the transport unit 4 moves to the top of the pipe support; then the pipe is hoisted onto the transport unit 4 by means of a crane and other equipment; then the electric telescopic element 2 fine-tunes the height of the transport unit 4 to leave a small gap between the bottom of the pipe on the transport unit 4 and the pipe support (the bottom of the pipe is located above the pipe support) to avoid collision with the pipe support during the movement of the pipe to the right; the transport unit 4 is then driven The pipeline moves to the right in the direction of v1; after the first pipeline moves to the right side of the welding unit 8, the transport unit 4 transports the second pipeline to the position where it fits with the first pipeline; at this time, the joint of the two pipelines is located on the inner side of the welding unit 8; then the electric telescopic cylinder 7 drives the fixing plate 6 and the pressing unit 5 to move downward, and the pressing unit 5 makes the pipeline fit to the transport unit 4; the pressing unit 5 cooperates with the transport unit 4 to limit the ends of the pipelines on both sides of the welding unit 8, which can prevent the ends of the pipelines from tilting up, so that the pipelines on both sides of the welding unit 8 can be in a horizontal state, which is convenient for the subsequent welding unit 8 to weld the pipeline joints; the welding unit 8 can move and weld along the pipeline joints, and the pipeline does not need to rotate; after the welding of the pipeline joints is completed Finally, the transport unit 4 on the right side of the welding unit 8 transports the welded pipe to the right, and the transport unit 4 on the left side of the welding unit 8 transports the next pipe to the right synchronously, until the joint of the pipe is located inside the welding unit 8, and the welding unit 8 works again; as the length of the spliced ​​pipe increases, the length of the pipe on the right side of the welding unit 8 becomes longer and longer, and the pipe does not need to be rotated through the surrounding welding of the welding unit 8; at the same time, the pressing unit 5 cooperates with the transport unit 4, not only to transport the pipe, but also to limit the end of the pipe, so that the end of the pipe on both sides of the welding unit 8 is always kept in a horizontal state, preventing the pipe end on both sides of the welding unit 8 from tilting, especially the pipe with increased length after splicing on the right side, to ensure the welding quality of the pipe joint; wait for the top layer After the pipeline transportation is completed, the electric telescopic element 2 drives the support frame 3 to move downward to the next layer of pipeline installation position, and repeats the above pipeline transportation and welding work; the electric telescopic element 2 drives the support frame 3 to rise and fall, which can adapt to the installation of pipelines at different heights, greatly improving the installation efficiency of pipelines in the integrated pipeline gallery; as the length of the spliced ​​pipeline increases, the pressing unit 5 can ensure that the part of the spliced ​​pipeline located on the right side of the welding unit 8 remains horizontal, but the end away from the welding unit 8 will still bend downward under the action of gravity. When the spliced ​​pipeline is transported to the right, the downward bent end of the pipeline is easy to hit the pipeline support, and the end of the spliced ​​pipeline against the pipeline support and then continue to move to the right is easy to aggravate the bending deformation of the pipeline, thereby damaging the welding point of the spliced ​​pipeline;In this embodiment, after the transportation unit 4 transports the first pipe to the right side of the welding unit 8, the worker pushes the mounting plate 22 so that the clamping groove of the clamping block 23 is clamped into the right end of the pipe, and the clamping block 23 can stably clamp the end of the pipe; when the spliced pipe is transported to the right, the detection fork 28 contacts the pipe support instead of the pipe end; reference; Figure 7 , when the spliced pipe drives the mounting plate 22 and the detection fork 28 to move to the right, the detection fork 28 will slide along the pipe support. When the point a on the detection fork 28 contacts the point b on the pipe support, when the spliced pipe continues to move to the right, due to the setting of the limit block 29, in Figure 7 state, the detection fork 28 can only rotate clockwise, so the detection fork 28 will turn upward around the point a, and the rotation center c point of the detection fork 28 itself will drive the mounting plate 22 to lift upward, and the mounting plate 22 can drive the end of the pipe to lift upward synchronously; when the detection fork 28 rotates to the vertical state, the end of the pipe crosses the pipe support; then when the pipe continues to be transported, the detection fork 28 is separated from the pipe support, and the detection fork 28 returns to the Figure 7 shown state under the elastic force of the torsion spring 30; it should be noted that after the pipe crosses the pipe support, in order to make the detection fork 28 smoothly separated from the pipe support, as Figure 3 shown, an avoidance groove can be opened at the bottom end of the mounting plate 22 to increase the clockwise rotation angle of the detection fork 28; it can also be as Figure 5 and Figure 7 shown, to reduce the bottom edge length of the right end of the detection fork 28; through the setting of the mounting plate 22, the clamping block 23 and the detection fork 28 of the present invention, the end of the detection fork 28 away from the pipe end is set as a V shape. When the bending of the pipe end is within the specified range, the detection fork 28 can contact the pipe support during the movement process. The detection fork 28 can replace the end of the pipe to collide with the pipe support. The detection fork 28 can push the end of the pipe to lift upward over the pipe support, avoiding the collision between the pipe end and the pipe support, preventing the pipe support from hindering the transportation of the pipe, making the pipe transportation smoother during long-distance transportation, increasing the transportation length of the pipe, and improving the pipe transportation efficiency.

[0021] Specifically, as Figure 3 shown, a first steel rope 24 is fixedly connected to each of the clamping blocks 23. One end of the first steel rope 24 away from the clamping block 23 passes through the mounting plate 24 and is fixedly connected to a sliding sleeve 25. The sliding sleeve 25 is horizontally slidably connected to the mounting plate 22; a coaxial thread sleeve one 26 is rotatably connected to the sliding sleeve 25; a thread sleeve two 27 is rotatably connected to the mounting plate 22; the thread sleeve two 27 is threadedly connected to the thread sleeve one 26; by rotating the thread sleeve two 27, the thread sleeve one 26 can be driven to drive the sliding sleeve 25 to horizontally slide on the mounting plate 22. The sliding sleeve 25 can drive one end of the first steel rope 24 to move synchronously, and the other end of the first steel rope 24 can drive the clamping block 23 to slide along the radial direction of the mounting plate 22; in Figure 3In the shown state, the first steel rope 24 is in a taut state. When the sliding sleeve 25 moves outward, it can drive the clamping block 23 to open outward through the first steel rope 24. The staff can adjust the distance between the clamping block 23 and the axis of the mounting plate 22 according to the diameter of the pipeline to be transported, so that the clamping block 23 can adapt to the clamping of pipelines with different diameters, and the adjustment is convenient.

[0022] Specifically, as Figure 3 and Figure 12 shown, the transportation unit 4 is composed of a support 9 and two guide rollers 10. The two guide rollers 10 are rotatably mounted on the support 9, and the axes of the two guide rollers 10 are perpendicular to each other. When pressing the pipeline, the guide rollers 10 of the transportation unit 4 and the guide rollers 10 of the pressing unit 5 are tangent to the outer wall of the pipeline. It should be noted that a motor can be set on the support 9 to drive the guide rollers 10 to rotate, and the transportation of the pipeline is completed through the rolling friction between the guide rollers 10 and the pipeline. Or the pipeline can be pushed to move to the right by equipment such as a crane. If the transportation of the pipeline is realized by equipment such as a crane, there is no need to set a motor on the support 9, and the guide rollers 10 play a role in reducing the friction when the pipeline moves.

[0023] Specifically, as Figure 9 , Figure 10 and Figure 12 shown, the welding unit 8 includes a bottom plate 11, a mounting ring 12, a rotating ring 13, a welding head 14, an electrical box 15, a second electric telescopic cylinder 16, a first friction wheel 17 and a second friction wheel 18. The bottom plate 11 is installed in the middle of the support frame 3. The mounting ring 12 is fixedly installed on the top of the bottom plate 11 and an opening for avoiding the pipeline is provided at the top. The central angle corresponding to the opening is greater than 90° and less than 180°. The rotating ring 13 is coaxially arranged with the mounting ring 12 and is rotatably installed inside the mounting ring 12. The rotating ring 13 has the same shape as the mounting ring 12. The welding head 14 is arranged inside the rotating ring 13. The fixed end of the second electric telescopic cylinder 16 is fixedly connected to the rotating ring 13, and the output end is fixedly connected to the welding head 14. The electrical box 15 is fixedly installed inside the rotating ring 13 and is used to control the operation of the welding head 14 and the second electric telescopic cylinder 16. The first friction wheel 17 is coaxially arranged with the rotating ring 13 and is fixedly connected to the rotating ring 13. The second friction wheel 18 is rotatably connected to the bottom plate 11 and is in transmission connection with the first friction wheel 17.

[0024] After the splicing joint of the pipeline is located directly above the welding head 14, the control system in the electrical box 15 controls the second electric telescopic cylinder 16 to drive the welding head 14 to move upward, so that the welding head 14 contacts the outer wall of the pipeline; then the motor (not shown in the figure) drives the second friction wheel 18 to rotate, the second friction wheel 18 drives the first friction wheel 17 to rotate, the first friction wheel 17 drives the rotating ring 13 to rotate inside the mounting ring 12, and the rotating ring 13 drives the welding head 14 to make a circular motion along the outer side of the pipeline to weld the splicing joint of the pipeline; after the rotating ring 13 rotates one circle, the welding work of the pipeline splicing joint is completed, and then the second electric telescopic cylinder 16 drives the welding head 14 to move downward to the initial position to prevent the welding head 14 from being knocked during the subsequent movement of the pipeline; there are two second friction wheels 18, and the two friction wheels 18 work synchronously, so that the rotating ring 13 can work more stably; by providing openings at the tops of the mounting ring 12, the rotating ring 13 and the first friction wheel 17, after the welding and transportation of the pipeline are completed, when the support frame 3 drives the welding unit 8 to move downward to the lower layer, the pipeline can be removed from the opening of the welding unit 8, which is convenient for the welding unit 8 to separate from the pipeline.

[0025] Specifically, as Figure 11 and Figure 12 shown, a first hydraulic cylinder 19 is fixedly installed on the support frame 3, and the free end of the first hydraulic cylinder 19 is fixedly connected to the fixing plate 6; a second hydraulic cylinder 20 is also fixedly installed on the support frame 3, and the free end of the second hydraulic cylinder 20 is fixedly connected to the bottom plate 11; the cross-sectional area of the piston rod at the free end of the second hydraulic cylinder 20 is twice that of the piston rod at the free end of the first hydraulic cylinder 19; the first hydraulic cylinder 19 and the second hydraulic cylinder 20 are connected through a conduit 21; the conduit 21 is fixed to the inner side of the support frame 3 by a buckle or a bolt; the two ends of the conduit 21 are respectively located below the free end of the first hydraulic cylinder 19 and above the free end of the second hydraulic cylinder 20.

[0026] In the initial state, the inscribed circle of the rectangle formed by the two guide rollers 10 of the pressing unit 5 and the two guide rollers 10 of the transportation unit 4 is concentric with the rotating ring 13; refer to Figure 12, when the pressing unit 5 cooperates with the transportation unit 4 to press the pipeline, the outer wall of the pipeline is tangent to the four guide rollers 10 and is concentric with the rotating ring 13; when the diameter of the pipeline to be transported changes from a large diameter on the left to a small diameter on the right, the position of the transportation unit 4 remains unchanged (the transportation unit is relatively fixed with the support frame 3), and the pressing unit 5 moves downward by an increased distance, with a height difference of h2; at this time, the rotating ring 13 of the welding unit 8 needs to move downward by a height of h3 to ensure concentricity with the small-diameter pipeline; when the transportation unit 4 does not move, h2 = 2h3; the downward movement of the pressing unit 5 is driven by the fixed plate 6; when the electric telescopic cylinder 7 drives the fixed plate 6 and the pressing unit 5 to move downward, the fixed plate 6 drives the free end of the hydraulic cylinder 19 to move downward synchronously, and the hydraulic oil in the hydraulic cylinder 10 enters the hydraulic cylinder 20 through the conduit 21; under the action of the hydraulic oil pressure, the free-end piston of the hydraulic cylinder 20 drives the bottom plate 11 to move downward; the bottom plate 11 drives the mounting ring 12, the rotating ring 13, the welding head 14, the electrical box 15, the electric telescopic cylinder 17, the friction wheel 17 and the friction wheel 18 to move downward synchronously; since the cross-sectional area of the free-end piston rod of the hydraulic cylinder 20 is twice that of the free-end piston rod of the hydraulic cylinder 19, the downward movement distance of the free-end piston of the hydraulic cylinder 19 is equal to twice the downward movement distance of the free-end piston of the hydraulic cylinder 20; when the pressing unit 5 cooperates with the transportation unit 4 to clamp pipelines of different diameters, the rotating ring 13 of the welding unit 8 is always concentric with the pipeline to be welded, and the welding unit 8 can complete the welding and splicing of pipelines of different diameters and can also ensure the welding quality of the pipelines.
