Description

Technical Field

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

[0002] When installing and constructing pipelines with high 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 transported to the upper end of the pipeline support in sequence, and the support is used to pre-support the pipelines; this reduces the difficulty of installation, and when the pipelines are completely laid, the adjustment units on the pipeline support can be used to achieve stable support for the pipelines.

[0003] However, since the pipe support is pre-fixed with the corridor wall, as shown in the attached instructions Figure 1 As shown, there is an installation height difference h1 between the brackets, which will cause the transversely moving end of the pipe to collide with the bracket. As the length and mass of the pipe increase through welding, the impact will become more severe. When the bracket cannot transport the pipe above it through its own deformation, the forced displacement of the pipe will cause the bracket to detach from the corridor wall; the free end of the pipe that loses support will become a longer cantilever beam, resulting in more deformation, and will cause more severe impact on subsequent brackets. On the one hand, it affects the transportation efficiency of the pipe. On the other hand, frequent impacts will cause uncertain deformation of the free end of the pipe.

[0004] See the Chinese utility model patent application number CN201621194507.6; the core of the means described therein is the idea of realizing transportation within the corridor through a number of equally spaced horizontal transport devices, which is essentially a relay transportation method that can more effectively solve the problem of transshipment. However, before transportation, each horizontal transport unit needs to be calibrated with each other; it is time-consuming and difficult, and multiple horizontal transport devices also mean higher transshipment costs.

[0008] As a further solution of the present invention, an avoidance groove is provided at the bottom end of the mounting plate.

[0009] As a further solution of the present invention, the transport unit is composed of a support and two guide rollers. The two guide rollers are rotatably mounted on the support, and the axes of the two guide rollers are perpendicular to each other.

[0033] refer to Figure 6, use a crane or other equipment to transport the transport device to the pipe splicing location inside the integrated pipe gallery; 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; 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 a crane or 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 above the pipe support) to avoid collision with the pipe support during the movement 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 along the pipeline joints for welding, and the pipelines do 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 splicing point 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, and the end of the pipe on both sides of the welding unit 8 is always kept in a horizontal state, preventing the pipe ends 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 seam; 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; by the electric telescopic element 2 driving the lifting of the support frame 3, it can adapt to the installation work of pipelines at different heights, greatly improving the installation efficiency of pipelines in the integrated pipeline corridor; 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 likely to hit the pipeline support, and the spliced pipeline end will continue to move to the right after it hits the pipeline support, which is likely to aggravate the bending deformation of the pipeline and damage the welding point of the spliced pipeline;In this embodiment, after the transport 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 slot of the clamping block 23 engages with 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 bracket. When point a on the detection fork 28 contacts point b on the pipe bracket, the spliced pipe continues to move to the right. Due to the setting of the limit block 29, Figure 7 In the state, the detection fork 28 can only rotate clockwise, so the detection fork 28 will flip upward around point a, and the rotation center point c of the detection fork 28 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 passes over the pipe support; then when the pipeline continues to be transported, the detection fork 28 is separated from the pipe support, and the detection fork 28 returns to the vertical state under the elastic force of the torsion spring 30. Figure 7 It should be noted that, after the pipe passes over the pipe support, in order to make the detection fork 28 can be smoothly separated from the pipe support, such as Figure 3 As shown, a avoidance groove can be opened at the bottom of the mounting plate 22 to increase the clockwise rotation angle of the detection fork 28; Figure 5 and Figure 7 As shown, the length of the bottom side of the right end of the detection fork 28 is reduced; the present invention is provided with the installation plate 22, the clamping block 23 and the detection fork 28, and the detection fork 28 is set to a V-shape at the end away from the pipe end. When the bending of the pipe end is within the specified range, the detection fork 28 can contact the pipe support during the movement. 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 up and pass 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 pipeline, and making the pipeline smoother during long-distance transportation. The transportation length of the pipeline can be increased, and the pipeline transportation efficiency can be improved.

[0034] Specifically, such as Figure 3 As shown, the clamping block 23 is fixedly connected with a steel rope 1 24, and the end of the steel rope 1 24 away from the clamping block 23 passes through the mounting plate 24 and is fixedly connected with a sliding sleeve 25, and the sliding sleeve 25 is horizontally slidably connected to the mounting plate 22; a coaxially arranged threaded sleeve 1 26 is rotatably connected to the sliding sleeve 25; the mounting plate 22 is rotatably connected with a threaded sleeve 27; the threaded sleeve 27 is threadedly connected to the threaded sleeve 1 26; by rotating the threaded sleeve 27, the threaded sleeve 1 26 can be driven to drive the sliding sleeve 25 to slide horizontally on the mounting plate 22, and the sliding sleeve 25 can drive one end of the steel rope 1 24 to move synchronously, and the other end of the steel rope 1 24 can drive the clamping block 23 to slide radially along the mounting plate 22; Figure 3In the state shown, the steel rope 24 is in a taut state. When the sliding sleeve 25 moves outward, the clamping block 23 can be driven to open outward through the 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 of different diameters and is easy to adjust.

[0035] Specifically, such as Figure 3 and Figure 12 As shown, the transport unit 4 consists of a support 9 and two guide rollers 10, and the two guide rollers 10 are rotatably installed on the support 9, and the axes of the two guide rollers 10 are perpendicular to each other; when the pipeline is compressed, the guide rollers 10 of the transport 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 pipeline transportation work is completed by the rolling friction between the guide rollers 10 and the pipeline; the pipeline can also be pushed to the right by a crane or other equipment. If the pipeline transportation is achieved by a crane or other equipment, there is no need to set a motor on the support 9, and the guide rollers 10 serve to reduce the friction when the pipeline moves.

[0036] Specifically, such as Figure 9 、 Figure 10 as well as Figure 12 As shown, the welding unit 8 includes a base plate 11, a mounting ring 12, a swivel 13, a welding head 14, an electrical box 15, an electric telescopic cylinder 2 16, a friction wheel 17 and a friction wheel 2 18; the base plate 11 is installed in the middle of the support frame 3; the mounting ring 12 is fixedly installed on the top of the base plate 11 and has an opening at the top for avoiding the pipeline, and the central angle corresponding to the opening is greater than 90° and less than 180°; the swivel 13 is coaxially arranged with the mounting ring 12 and is rotatably installed inside the mounting ring 12 The swivel 13 has the same shape as the mounting ring 12; the welding head 14 is arranged on the inner side of the swivel 13; the fixed end of the electric telescopic cylinder 2 16 is fixedly connected to the swivel 13, and the output end is fixedly connected to the welding head 14; the electrical box 15 is fixedly installed on the inner side of the swivel 13 and is used to control the operation of the welding head 14 and the electric telescopic cylinder 2 16; the friction wheel 17 is coaxially arranged with the swivel 13 and fixedly connected to the swivel 13; the friction wheel 2 18 is rotatably connected to the base plate 11 and is transmission-connected to the friction wheel 17.

[0037] After the joint of the pipe is located directly above the welding head 14, the control system in the electrical box 15 controls the electric telescopic cylinder 2 16 to drive the welding head 14 to move upward so that the welding head 14 contacts the outer wall of the pipe; then the motor (not shown in the figure) drives the friction wheel 2 18 to rotate, and the friction wheel 2 18 drives the friction wheel 17 to rotate, and the 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 pipe to weld the joint of the pipe; after the rotating ring 13 rotates one circle, the pipe joint is completed. The welding work is completed, and then the electric telescopic cylinder 2 16 drives the welding head 14 to move downward to the initial position to avoid the welding head 14 from being bumped during the subsequent movement of the pipeline; there are two friction wheels 18, and the two friction wheels 18 work synchronously, so that the swivel 13 can work more stably; by providing openings at the top of the mounting ring 12, the swivel 13 and the friction wheel 1 17, after completing the welding and transportation work of the pipeline, when the support frame 3 drives the welding unit 8 to move to the lower layer, the pipeline can be moved out of the opening of the welding unit 8, which facilitates the separation of the welding unit 8 from the pipeline.

[0038] Specifically, such as Figure 11 and Figure 12 As shown, a hydraulic cylinder 19 is fixedly mounted on the support frame 3, and the free end of the hydraulic cylinder 19 is fixedly connected to the fixed plate 6; a hydraulic cylinder 2 20 is also fixedly mounted on the support frame 3, and the free end of the hydraulic cylinder 2 20 is fixedly connected to the base plate 11; the cross-sectional area of the free end piston rod of the hydraulic cylinder 2 20 is twice the cross-sectional area of the free end piston rod of the hydraulic cylinder 19; the hydraulic cylinder 19 and the hydraulic cylinder 2 20 are connected by a conduit 21; the conduit 21 is fixed to the inner side of the support frame 3 by a buckle or bolt; the two ends of the conduit 21 are respectively located below the free end of the hydraulic cylinder 19 and above the free end of the hydraulic cylinder 2 20.

[0039] 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 transport unit 4 is concentric with the rotating ring 13; Figure 12When the pressing unit 5 cooperates with the transport unit 4 to press the pipe, the outer wall of the pipe is tangent to the four guide rollers 10 and is concentric with the swivel 13; when the diameter of the pipe to be transported changes from the large diameter on the left to the small diameter on the right, the position of the transport unit 4 remains unchanged (the transport unit and the support frame 3 remain relatively fixed), the pressing unit 5 moves downward a greater distance, and the height difference is h2; at this time, the swivel 13 of the welding unit 8 needs to move downward by a height of h3 to ensure that it is concentric with the small diameter pipe; when the transport 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 passes through the conduit 21 enters the hydraulic cylinder 20; under the action of hydraulic oil pressure, the free end piston of the hydraulic cylinder 20 drives the base plate 11 to move downward; the base plate 11 drives the mounting ring 12, the swivel 13, the welding head 14, the electrical box 15, the electric telescopic cylinder 2 17, the friction wheel 17 and the friction wheel 2 18 to move downward synchronously; since the cross-sectional area of the free end piston rod of the hydraulic cylinder 20 is twice the cross-sectional area 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 transport unit 4 to clamp pipes of different diameters, the swivel 13 of the welding unit 8 is always in a concentric state with the pipe to be welded, and the welding unit 8 can complete the welding and splicing of pipes of different diameters, while also ensuring the welding quality of the pipes.
