Description

Technical Field

[0001] The present application relates to the technical field of pipeline construction devices, and particularly to a pipeline rotation docking device and method for construction. Background Art

[0002] Pipeline construction is a core link in projects such as water conservancy, petroleum, and municipal engineering, involving multi-disciplinary intersections and high-precision operations. Pipeline connection is a key process in pipeline construction, and its quality directly determines the project life, safety, and economy. For pipelines connected by flange plates, the flanges need to be accurately aligned, and the pipeline needs to be rotated during the alignment process.

[0003] The existing alignment method usually uses lifting equipment or brackets to fix the pipeline, and then manually uses a crowbar to gently pry the flange edge to rotate the pipeline to gradually align the flange holes. However, for some large-diameter and heavy pipelines, it is difficult to adjust manually.

[0004] Here, the patent document with the publication number CN118128967A is cited. It discloses a pipeline docking device for water conservancy construction. Through the meshing between the second bevel gear and each first bevel gear, the rotating shaft key-connected to the first bevel gear rotates, and then the wheel plate drives the clamping roller to rotate until the axis of the clamping roller is parallel to the axis of the outer ring. Then, the control device controls the clamping roller to rotate, so that the pipeline rotates. However, this solution will cause friction between the clamping roller and the pipeline when the pipeline rotates, thereby reducing the service life of the equipment and having a high cost.

[0005] It should be noted that the information in the above background art section is only used to strengthen the understanding of the background art of the present application.

Detailed implementation manners

[0020] To make the objectives, features and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific implementation manners. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0021] The inventor found through analyzing the prior art that: the essential reason why the prior art solutions are difficult to achieve the rotary docking of some large-diameter and heavy pipelines is that it is laborious to pry manually, difficult to grasp the accuracy, and the efficiency is low, while the structures of existing automated devices are relatively complex and the design and assembly costs are relatively high.

[0022] Based on the above analysis, one of the core technical concepts of the present application is to clamp the outer wall of the pipe body to be docked by at least two limiting rings in the roller, rotate the roller axially, and align the connection positions of the first pipe body and the second pipe body.

[0023] Refer to Figures 1-7, showing a pipe rotary docking device provided in an embodiment of the present application, which is used to dock a first pipe body 61 to a second pipe body 62. The device includes: a base 1, a control component, a first limiting component 2, a first support seat 41, and a power component 5; The first support seat 41 is arranged on the base 1; the first limiting component 2 is rotatably arranged on the first support seat 41; The first limiting component 2 includes a first roller 20, a first limiting ring 210, and a second limiting ring 220; the power component 5 is connected to the first roller 20; the first limiting ring 210 is connected to the inner wall of the first roller 20 through a first telescopic rod 211; the second limiting ring 220 is connected to the inner wall of the first roller 20 through a second telescopic rod 221; During construction, the first pipe body 61 passes through the first limiting ring 210 and the second limiting ring 220, and the control component drives the first telescopic rod 211 and the second telescopic rod 221 to make the first limiting ring 210 and the second limiting ring 220 move relative to each other to clamp the outer wall of the first pipe body 61; the control component drives the power component 5 to make the first roller 20 rotate axially and align the connection position of the first pipe body 61 and the second pipe body 62.

[0024] In the embodiment of the present application, aiming at the problem that it is difficult to realize the rotary docking of some large-diameter and heavy pipes in the prior art, the present application provides a solution that the first limiting ring 210 and the second limiting ring 220 move relative to each other to clamp the outer wall of the first pipe body 61, make the first roller 20 rotate axially, and align the connection position of the first pipe body 61 and the second pipe body 62. Specifically: the first support seat 41 is arranged on the base 1; the first limiting component 2 is rotatably arranged on the first support seat 41; the first limiting component 2 includes a first roller 20, a first limiting ring 210, and a second limiting ring 220; the power component 5 is connected to the first roller 20; the first limiting ring 210 is connected to the inner wall of the first roller 20 through a first telescopic rod 211; the second limiting ring 220 is connected to the inner wall of the first roller 20 through a second telescopic rod 221; during construction, the first pipe body 61 passes through the first limiting ring 210 and the second limiting ring 220, and the control component drives the first telescopic rod 211 and the second telescopic rod 221 to make the first limiting ring 210 and the second limiting ring 220 move relative to each other to clamp the outer wall of the first pipe body 61; the control component drives the power component 5 to make the first roller 20 rotate axially and align the connection position of the first pipe body 61 and the second pipe body 62. The present application solves the problem of rotary docking of some large-diameter and heavy pipes, improves the service life of the equipment and reduces the cost.

[0025] Next, a pipe rotary docking device for construction in this exemplary embodiment will be further described.

[0026] It should be noted that the first telescopic rod 211 and the second telescopic rod 221 can be arranged on the opposite sides of the inner wall of the first roller 20. At least one rubber ring can be arranged on the inner side wall of the limiting ring. The inner diameter of the rubber ring is slightly smaller than that of the limiting ring and the rubber rings are arranged along the axial direction of the limiting ring. When clamping the first pipe body 61, the rubber rings and the inner wall of the limiting ring are in contact with the outer wall of the first pipe body 61 at the same time. At this time, the rubber rings will undergo adaptive deformation according to the outer wall of the first pipe body 61, which can increase the contact area with the first pipe body 61 and also prevent the first pipe body 61 from sliding in the limiting ring when it rotates. At the same time, in order to increase the contact area with the first pipe body 61, the shape of the inner ring of the limiting ring can not be a conventional or complete circle, but can also be an ellipse, or an elastic or inelastic convex structure is provided. However, the axis of the first pipe body 61 when it is clamped needs to be kept consistent with the axis of the roller to ensure that the first pipe body 61 can rotate along the axial direction.

[0027] The length of the roller can be 2-5 times the outer wall diameter of the first pipe body 61, which can ensure that the first pipe body 61 is fully supported in the axial direction as much as possible; the limiting rings are evenly arranged in the axial direction of the roller; the first support seat 41 and the first limiting component 2 can be connected by rollers or bearings; at least a pair of crawler wheels can be arranged at the bottom of the base 1 to increase the overall flexibility of the device; adjustable height foot pads can also be arranged at the bottom of the base 1 to cope with the construction environment of uneven ground.

[0028] Refer to Figures 2-4 In an embodiment of the present application, the first limiting component 2 further includes: a third limiting ring 230 and a third telescopic rod 231; The third limiting ring 230 is connected to the inner wall of the first roller 20 through the third telescopic rod 231; the first telescopic rod 211 and the third telescopic rod 231 are arranged on the same side of the inner wall of the first roller 20; the first limiting ring 210 and the third limiting ring 230 are respectively arranged at both ends of the second limiting ring 220 in the axial direction; When construction is carried out, the control component drives the third telescopic rod 231 to move the third limiting ring 230 to be connected to the outer wall of the first pipe body 61.

[0029] It should be noted that by arranging the first telescopic rod 211 and the third telescopic rod 231 on the same side of the inner wall of the first drum 20, the force application points of the first limiting ring 210 and the third limiting ring 230 on the outer circumference of the outer wall of the first pipe 61 can be kept on the same side. At the same time, by arranging the first limiting ring 210 and the third limiting ring 230 at the two axial ends of the second limiting ring 220 respectively, the torques of the first limiting ring 210, the second limiting ring 220 and the third limiting ring 230 in the axial direction of the outer wall of the first pipe 61 can be kept balanced, so as to stably clamp the outer wall of the first pipe 61. And because the three limiting rings are arranged side by side, no excessive bending moment will be generated.

[0030] Referring to Figures 5-6 , in an embodiment of the present application, the first telescopic rod 211 and the second telescopic rod 221 are arranged on the same side of the inner wall of the first drum 20; the first telescopic rod 211, the second telescopic rod 221 and the third telescopic rod 231 are hydraulic telescopic rods; The first limiting assembly 2 further includes: a hydraulic pump, a reversing valve and a flow dividing and collecting valve; The hydraulic pump, the reversing valve, the flow dividing and collecting valve, the first telescopic rod 211, the second telescopic rod 221 and the third telescopic rod 231 form a hydraulic oil circuit; wherein, the outlet of the hydraulic pump is connected to the inlet of the reversing valve; the second telescopic rod 221 is connected to the first working port of the reversing valve, the first telescopic rod 211 and the third telescopic rod 231 are connected to the second working port of the reversing valve, and the oil circuits of the first telescopic rod 211 and the third telescopic rod 231 are arranged in parallel through the flow dividing and collecting valve; When construction is carried out, the first telescopic rod 211, the second telescopic rod 221 and the third telescopic rod 231 move at the same speed.

[0031] It should be noted that in this embodiment, the telescopic control of the first telescopic rod 211, the second telescopic rod 221 and the third telescopic rod 231 is realized through a hydraulic system. The hydraulic pump is used to output high-pressure oil in the fuel tank to the reversing valve and is driven by the control assembly.

[0032] When the first telescopic rod 211, the second telescopic rod 221 and the third telescopic rod 231 are all arranged on the same side of the inner wall of the first drum 20, in order to realize the clamping of the first pipe 61 by the three limiting rings, it is necessary to ensure that while the first telescopic rod 211 and the third telescopic rod 231 extend / retract synchronously, the second telescopic rod 221 can retract / extend synchronously, that is, the first telescopic rod 211 and the third telescopic rod 231 move in the same direction, while the second telescopic rod 221 moves in the opposite direction.

[0033] The reversing valve can be a three-position four-way valve, which is used to control the flow direction of hydraulic oil and switch the movement direction of the hydraulic cylinder. The first telescopic rod 211 and the third telescopic rod 231 are combined pipelines arranged in parallel, and the second telescopic rod 221 is a separate pipeline. The flow dividing and collecting valve is used to forcibly distribute the total flow to the first telescopic rod 211 and the third telescopic rod 231, so that the two can move synchronously. By adjusting the flow distribution ratio, the synchronous error caused by uneven load can also be eliminated.

[0034] As an example, when the reversing valve is in the left position, the hydraulic oil sequentially passes through the reversing valve and is output to the rod chamber of the second telescopic rod 221 and the flow dividing and collecting valve, and is output from the flow dividing and collecting valve to the rodless chamber of the first telescopic rod 211 and the rodless chamber of the third telescopic rod 231; at this time, the first telescopic rod 211 and the third telescopic rod 231 extend, while the second telescopic rod 221 retracts; When the reversing valve is in the right position, the hydraulic oil is output through the reversing valve to the rodless chamber of the second telescopic rod 221, the rod chamber of the first telescopic rod 211 and the rod chamber of the third telescopic rod 231; at this time, the first telescopic rod 211 and the third telescopic rod 231 retract, while the second telescopic rod 221 extends.

[0035] In a specific embodiment of the present application, the hydraulic system of this embodiment can also adopt a low-pressure accumulator to realize a design without an oil tank, and then the low-pressure accumulator is arranged on the side plate 201 of the first limiting component 2 away from the limiting guide rail 2011, so that the entire hydraulic system is embedded in the first limiting component 2, ensuring that the operation of the hydraulic system will not affect the rotation of the first limiting component 2 and is more suitable for scenarios with limited space.

[0036] In a specific embodiment of the present application, the hydraulic pump can also be a bidirectional variable hydraulic pump, which is used to directly drive the forward and reverse flow of hydraulic oil to replace the original hydraulic pump and reversing valve, thereby reducing the volume of the hydraulic system.

[0037] Refer to Figures 3-4 , in an embodiment of the present application, two side plates 201 parallel to each other are provided inside the first roller 20; rollers are respectively provided on both sides of the limiting ring of the first limiting component 2; the side plate 201 is provided with a limiting guide rail 2011 corresponding to the roller; When construction is carried out, the limiting ring of the first limiting component 2 moves along the length direction of the limiting guide rail 2011.

[0038] It should be noted that the side plate 201 can limit the limiting ring of the first limiting component 2 from both sides, ensuring that the limiting ring can only move along the length direction of the corresponding telescopic rod. When the first pipe body 61 is installed and the first limiting component 2 rotates, the side plate 201 is used to support the limiting ring of the first limiting component 2 to avoid excessive radial load on the telescopic rod.

[0039] Referring Figure 1 , in an embodiment of the present application, it further includes: a second limiting component 3 and a second support seat 42; The second support seat 42 is arranged on the base 1; the second limiting component 3 is rotatably arranged on the second support seat 42; The second limiting component 3 includes a second roller 30 and at least two limiting rings; the limiting rings of the second limiting component 3 are respectively connected to the inner wall of the second roller 30 through telescopic rods; the telescopic rods of the second limiting component 3 are arranged perpendicular to the axis of the telescopic rods of the first limiting component 2; During construction, the control component drives the telescopic rods of the second limiting component 3 to make at least two limiting rings of the second limiting component 3 move relative to each other to clamp the outer wall of the first pipe body 61; the control component drives the power component 5 to rotate the second roller 30 axially.

[0040] It should be noted that the second limiting component 3 can have the same structure as the first limiting component 2 in any embodiment of the present application. The telescopic rods of the second limiting component 3 are arranged perpendicular to the axis of the telescopic rods of the first limiting component 2, so that the second limiting component 3 can clamp the first pipe body 61 from different angles, and can further serve as a supplement to the force application points of the first pipe body 61 in the first limiting component 2 to ensure the stability of the first pipe body 61 during rotational docking.

[0041] Referring Figure 1 and Figure 5 , as an example, the second limiting component 3 includes: a second roller 30, a fourth limiting ring, a fifth limiting ring and a sixth limiting ring; the power component 5 is connected to the second roller 30; the fourth limiting ring is connected to the inner wall of the second roller 30 through a fourth telescopic rod; the fifth limiting ring is connected to the inner wall of the second roller 30 through a fifth telescopic rod; the sixth limiting ring is connected to the inner wall of the second roller 30 through a sixth telescopic rod; the fourth limiting ring and the sixth limiting ring are respectively arranged at both axial ends of the fifth limiting ring; the fourth telescopic rod, the fifth telescopic rod and the sixth telescopic rod are arranged on the same side of the inner wall of the second roller 30; When construction is carried out, the first pipe body 61 passes through the fourth limiting ring, the fifth limiting ring and the sixth limiting ring, and the control assembly drives the fourth telescopic rod, the fifth telescopic rod and the sixth telescopic rod to move the fourth limiting ring, the fifth limiting ring and the sixth limiting ring to clamp the outer wall of the first pipe body 61; wherein, the fourth limiting ring and the sixth limiting ring move in the same direction, and the fifth limiting ring moves in the opposite direction to the fourth limiting ring.

[0042] Referring to Figure 7 , in an embodiment of the present application, the first support seat 41 and the second support seat 42 are movably arranged on the guide rail of the base 1; the first support seat 41 and the second support seat 42 are connected by an adjustable telescopic rod 43; When construction is carried out, the control assembly drives the first support seat 41 and the second support seat 42 to translate synchronously along the guide rail of the base 1, so that the first pipe body 61 approaches the second pipe body 62.

[0043] It should be noted that the adjustable telescopic rod 43 can ensure that the first support seat 41 and the second support seat 42 can adjust the support points of the first pipe body 61 to ensure the stability during rotational docking when installing the first pipe body 61, and can also move in coordination during translation. It can be understood that when adjusting the distance between the first support seat 41 and the second support seat 42, the position of the power gear 502 in the power shaft 50 of the power assembly 5 should be correspondingly adjusted to ensure that the roller gear 501 and the power gear 502 can cooperate.

[0044] Referring to Figure 5 , Figure 7 and Figure 8 , in an embodiment of the present application, the power assembly 5 includes two power shafts 50 respectively arranged on both sides of the base 1; the axis of the power shaft 50 is arranged parallel to the guide rail of the base 1; both end faces of the first roller 20 and the second roller 30 are provided with roller gears 501; a plurality of power gears 502 matching with the roller gears 501 are arranged along the axial direction of the two power shafts 50; When construction is carried out, the power shaft 50 drives the roller gear 501 through the power gear 502 to make the first roller 20 and the second roller 30 rotate synchronously along the axis.

[0045] It should be noted that by driving the first roller 20 and the second roller 30 through the power shaft 50 provided on the base 1, it can be ensured that the first roller 20 and the second roller 30 can rotate synchronously without deviation, and the power shaft 50 can output a relatively stable and sufficiently large torque, which is more suitable for large-diameter and heavy-weight pipes. The rotation angle of the first pipe body 61 can be accurately controlled by the cooperation of the roller gear 501 and the power gear 502. For pipes that do not need to rotate at a large angle, the gear teeth of the roller gear 501 can be distributed only on one side close to the power gear 502.

[0046] As an example, the power shaft 50 may also be movably disposed on the base 1 along the axial direction, so that the power shaft 50 , the first roller 20 and the second roller 30 may move synchronously along the guide rail of the base 1 .

[0047] In one embodiment of the present application, both the first support seat 41 and the second support seat 42 are provided with a locking mechanism; When the first tube 61 completes its rotation, the locking mechanism of the first support seat 41 is fixedly connected to the first roller 20 , and the locking mechanism of the second support seat 42 is fixedly connected to the second roller 30 .

[0048] It should be noted that the locking mechanism can be a toothed fixing member that can be lifted and lowered to cooperate with the drum gear 501, or a movable latch that is inserted into a positioning slot / hole on the outer wall of the drum, so that the drum cannot rotate. The locking mechanism can be driven by the control assembly.

[0049] In one embodiment of the present application, both the first support seat 41 and the second support seat 42 are provided with a telescopic mechanism; When the rotation of the first roller 20 and the second roller 30 is locked, the telescopic mechanism of the first support seat 41 drives the first roller 20 to lift, and the telescopic mechanism of the second support seat 42 drives the second roller 30 to lift synchronously, so that the roller gear 501 and the power gear 502 are disengaged, and the axes of the first tube body 61 and the second tube body 62 are at the same height.

[0050] It should be noted that, since the height of the base 1 is not easy to adjust directly, the height of the first tube 61 and the second tube 62 may not be aligned in actual working conditions. Therefore, the telescopic mechanism is provided to enable the drum gear 501 and the power gear 502 to be disengaged, so as to facilitate the movement of the first support seat 41 and the second support seat 42 along the guide rail of the base 1, and to lift the first tube 61 so that it can match the height of the second tube 62. The telescopic mechanism can be driven by the control component.

[0051] The above is the description of the device embodiments of the present application.
