Wherein the calibration table is connected to the base in a lifting mode, and the two clamping mechanisms are coaxially arranged and arranged on the calibration table in a spaced mode in the first direction so as to be used for clamping the butt joint ends of two pipelines to be in butt joint correspondingly. The clamping mechanism comprises two clamping jaws arranged in the second direction in a spaced mode and an adjusting shaft connected with one clamping jaw so that the clamping jaws can rotate along with the adjusting shaft. The observation part is connected to the adjusting shaft and used for displaying whether leveling is conducted or not. The two clamping jaws can move in the second direction and hold the pipeline. When the calibration table ascends and descends relative to the base, the butt joint end of the pipeline and the clamping jaw can rotate relative to the calibration table. And when the observation piece rotating along with the clamping jaw points to the preset position, the two butt joint pipelines can rotate to the same axis, and therefore the leveling procedure is completed.

Technical Field

[0001] The utility model relates to the technical field of pipeline connection, in particular to a pipeline butt-jointing leveling device. Background Art

[0002] Double-walled pipes are commonly used on ships to transport liquids or gases. Double-walled pipes have the advantages of good corrosion resistance, strong pressure resistance, high thermal insulation, stable structure, and convenient installation and maintenance, which can meet the use requirements of ship pipeline systems in marine environments. When laying double-walled pipes on ships and docking them, the two double-walled pipes need to be leveled to improve the connection effect between the two pipe walls, which helps to ensure the stable operation of the pipeline system, reduce vibration and noise, ensure the safe operation of the pipeline system, and extend the service life of the pipeline.

[0003] The butt joint between two double-walled pipes usually requires the assistance of an adjustment device to complete the welding of the two double-walled pipes.

It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0029] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0030] The butt joint between two double-walled pipes usually requires the assistance of an adjustment device to complete the welding of the two double-walled pipes. The existing adjustment device usually includes a support mechanism, and the support mechanism is generally a support part that can be raised and lowered. A limit seat is fixedly installed on the top of the support part, and the butt joint of the two double-walled pipes is fixed to the top of the support part through the limit seat. At the same time, a set of support mechanisms are installed on the periphery of the two double-walled pipes that need to be butt jointed, and the two double-walled pipes are raised and lowered by the support part, and a level ruler is used in conjunction to complete the leveling work before the double-walled pipe welding butt joint operation.

[0031] However, for this docking method, during the process of lifting and lowering the two double-walled pipes, the operator needs to use a level ruler to repeatedly confirm whether the two double-walled pipes are at the same level, which makes the entire adjustment operation more cumbersome and reduces the efficiency of the double-walled pipe docking. Therefore, a pipeline docking leveling device is proposed to solve the above problem.

[0032] The scheme is further illustrated by the following examples:

[0033] Figure 1 It is a schematic diagram of a pipeline butt-jointing and leveling device according to an embodiment of the utility model. Figure 2 yes Figure 1 A magnified view of point A. Figure 3 yes Figure 2 An enlarged view of point B.

[0034] See also Figure 1 , Figure 2 and Figure 3 The pipe docking and leveling device of this embodiment can be used to clamp two pipes to be docked and calibrate them so that the two pipes to be docked can be accurately docked. The pipes can be set as ordinary pipes or double-walled pipes, etc., which are not limited here.

[0035] In this embodiment, when two pipes are butt-jointed, the axis of the pipes is defined as the longitudinal direction, that is, the two pipes are butt-jointed along a first direction, and the direction along the horizontal direction and perpendicular to the first direction is defined as the second direction. The end of the pipe used for butt-jointing with another pipe is defined as the butt-joint end.

[0036] Specifically, the pipeline docking and leveling device may include a base 10 , a calibration platform 11 , two observation pieces 23 and two clamping mechanisms 20 .

[0037] The calibration platform 11 is arranged on the base 10 in a liftable manner, so that the calibration platform 11 can move vertically relative to the base 10. Two clamping mechanisms 20 are arranged on the calibration platform 11 at intervals to clamp the butt ends of the pipes, and are lifted and lowered along the calibration platform 11 to drive the butt ends to move, thereby achieving leveling of the two butt ends. Two observation pieces 23 are respectively arranged on the clamping mechanisms 20, so as to determine whether the two butt ends are in a leveling state by observing the observation pieces 23.

[0038] See also Figure 1 In this embodiment, the base 10 is used to support the calibration platform 11 and the observation piece 23 and the clamping mechanism 20 arranged on the calibration platform 11.

[0039] Specifically, the base 10 is a horizontally arranged plate. The calibration platform 11 is horizontally arranged and arranged above the base 10. Specifically, the calibration platform 11 is arranged above the base 10 through a lifting mechanism 12 to achieve the lifting of the calibration platform 11.

[0040] See also Figure 1 The lifting mechanism 12 may include a power member 13 and a plurality of telescopic rods 14 .

[0041] The power member 13 may include a free end that can be lifted and lowered relative to the base 10, and the free end is fixedly connected to the bottom of the calibration platform 11. That is, the power member 13 may be connected between the base 10 and the calibration platform 11 to drive the calibration platform 11 to lift and lower relative to the base 10.

[0042] Preferably, the power member 13 is connected to the center of the calibration platform 11 .

[0043] In this embodiment, the power member 13 can be configured as a gas cylinder or an oil cylinder to drive the calibration platform 11 to move up and down in the vertical direction.

[0044] In some other embodiments, the power member 13 can be configured as a linear motor or a motor and a lead screw, etc., to drive the calibration platform 11 to move up and down.

[0045] In addition, a plurality of telescopic rods 14 are arranged at intervals along the circumference of the calibration platform 11, that is, the plurality of telescopic rods 14 are distributed on the outer circumference of the power member 13. The telescopic rods 14 are connected between the base 10 and the calibration platform 11 to guide and limit the calibration platform 11.

[0046] In this embodiment, there are four telescopic rods 14, which are arranged at four corners of the calibration platform 11. In other embodiments, the number and arrangement of the telescopic rods 14 can be set according to specific needs.

[0047] In this embodiment, the telescopic rod 14 includes a fixed section fixed to the base 10 and a telescopic section fixedly connected to the bottom of the calibration platform 11. When the telescopic section is retracted downward into the fixed section, that is, when the fixed section is sleeved on the outer periphery of the telescopic section, the calibration platform 11 descends. When the telescopic section extends upward from the fixed section, the calibration platform 11 rises.

[0048] See also Figure 1 The two clamping mechanisms 20 can be arranged on the calibration platform 11 at intervals along the first direction, and the two clamping mechanisms 20 are arranged coaxially to clamp the butt ends of the two pipes to be butted. Coaxial here means that the center lines of the two clamping mechanisms along the second direction are located on the same straight line.

[0049] See also Figure 2 and Figure 3 The clamping mechanism 20 may include an adjusting shaft 22 and two clamping jaws 21 .

[0050] The two clamping jaws 21 are spaced apart along the second direction, and the two clamping jaws 21 can move relative to each other along the second direction, so that the two clamping jaws 21 can approach each other and hold the pipe together, or the two clamping jaws 21 can move away from each other to release the pipe.

[0051] Figure 4 yes Figure 1 A partial schematic diagram of the clamping claw structure of the pipe docking and leveling device.

[0052] See also Figure 2 and Figure 4 The clamping jaw 21 may include a supporting plate 211 and a clamping plate 212 .

[0053] The clamping plate 212 may be located inside the supporting plate 211 , and the clamping plate 212 is connected to the supporting plate 211 via an adjusting shaft 22 , so that the clamping plate 212 can rotate relative to the supporting plate 211 .

[0054] In this embodiment, the clamping plate 212 is arc-shaped, and the convex surface of the clamping plate 212 faces outward, so that the clamping plates 212 of the two clamping jaws 21 can be tightly clamped on the outer peripheral side of the pipe.

[0055] In some other embodiments, the clamping plate 212 may also be configured as a flat plate or other shapes, and the clamping plate 212 can be clamped on the outer peripheral side of the pipe.

[0056] See also Figure 2 and Figure 4 The clamping jaw 21 may further include a plurality of balls 213 .

[0057] Among them, a plurality of balls 213 can be arranged on the inner side wall of the clamping plate 212, and the balls 213 can be rotatably arranged on the clamping plate 212. When the clamping plate 212 is clamped on the outer peripheral side of the pipe, the balls 213 can abut against the outer peripheral side of the pipe, thereby reducing the friction between the clamping plate 212 and the pipe, and avoiding displacement between the clamping plate 212 and the pipe during the leveling process to cause scratches on the surface of the pipe.

[0058] See also Figure 1 and Figure 3 The axis of the adjusting shaft 22 extends along the second direction and is connected to the center of one of the clamping jaws 21 so that the clamping jaw 21 can rotate along with the adjusting shaft 22 .

[0059] In some other embodiments, the two clamping jaws 21 of the clamping mechanism 20 can be respectively connected to the two supporting plates 211 through the adjusting shaft 22 so that the two clamping jaws 21 can rotate relative to the supporting plate 211 .

[0060] See also Figure 4 The clamping jaw 21 may further include a rotating bearing 24 , a thrust bearing 25 and a retaining ring 26 .

[0061] The rotating bearing 24 is disposed between the adjusting shaft 22 and the supporting plate 211 , so that the adjusting shaft 22 can rotate relative to the supporting plate 211 , thereby enabling the clamping jaw 21 to rotate relative to the supporting plate 211 .

[0062] The outer periphery of the adjusting shaft 22 is provided with a thrust bearing 25 and a retaining ring 26, and the thrust bearing 25 and the retaining ring 26 are both located between the support plate 211 and the clamping jaw 21, and the thrust bearing 25 is located on the outside of the retaining ring 26. When the clamping jaw 21 is clamped on the outer periphery of the pipe, the thrust bearing 25 and the retaining ring 26 can offset the axial force between the adjusting shaft 22 and the rotating bearing 24, thereby avoiding displacement between the adjusting shaft 22 and the rotating bearing 24.

[0063] See also Figure 1 and Figure 2 The clamping mechanism 20 may further include a driving assembly 30. The driving assembly 30 may be used to drive the two clamping jaws 21 to move.

[0064] The driving assembly 30 may include a screw 32 and two bases 31 . The two bases 31 are spaced apart on the calibration platform 11 along the second direction, the screw 32 is connected between the two bases 31 , and the screw 32 can rotate relative to the base 31 .

[0065] In this embodiment, the two clamping jaws 21 are symmetrically arranged at opposite ends of the screw rod 32, and the clamping jaws 21 can move along the second direction driven by the screw rod 32, so that the two clamping jaws 21 move toward or away from each other and then clamp on the outer peripheral side of the pipe.

[0066] Specifically, in this embodiment, the clamping jaw 21 is connected to the screw rod 32 through the support plate 211, so that the screw rod 32 can drive the support plate 211 and the clamping plate 212 to move.

[0067] See also Figure 2 The clamping mechanism 20 may further include a guide member 33. The guide member 33 is connected between the two bases 31, and the guide member 33 extends along the second direction. The clamping jaw 21 is sleeved on the outer periphery of the guide member 33 and can move along the guide member 33.

[0068] In this embodiment, two guide members 33 are provided, and the two guide members 33 are arranged at intervals along the first direction and are located between the two bases 31. The two guide members 33 can limit the clamping jaw 21 to prevent the clamping jaw 21 from changing its posture during movement.

[0069] In this embodiment, the clamping jaw 21 is connected to the guide member 33 via the support plate 211 , so that the support plate 211 can move along the guide member 33 .

[0070] See also Figure 2 The driving assembly 30 may further include a hand wheel 34. The hand wheel 34 is connected to one end of the screw rod 32 to drive the screw rod 32 to rotate around its own axis.

[0071] The hand wheel 34 can be driven manually or by a motor to drive the screw rod 32 to rotate, so that the screw rod 32 can drive the clamping jaw 21 to move.

[0072] See also Figure 1 and Figure 3 Two observation pieces 23 are respectively arranged on the adjustment shafts 22 of the two clamping mechanisms 20 to display whether the clamping mechanisms 20 have leveled the two pipes during the leveling process.

[0073] When both observation pieces 23 are shown to be leveled, the clamping jaws 21 on the two clamping mechanisms 20 are in a coaxial state, and the axes of the two pipes are located in the same straight line.

[0074] See also Figure 3 The observation piece 23 may include a calibration scale plate 231 and a calibration pointer 232 .

[0075] The calibration scale plate 231 is disposed on the support plate 211 . The calibration pointer 232 is disposed on the adjustment shaft 22 and is located on a side of the adjustment shaft 22 away from the clamping plate 212 .

[0076] In this embodiment, since the clamp 21 includes a support plate 211 and a clamp plate 212, and the adjustment shaft 22 passes through the support plate 211 and is connected to the clamp plate 212, the calibration pointer 232 is fixed on the adjustment shaft 22 and is located on the outside of the support plate 211, so that the calibration pointer 232 can point to the calibration scale plate 231 located on the support plate 211.

[0077] When the calibration pointer 232 points to a preset position on the calibration scale plate 231 , the axes of the two pipes are located in the same straight line.

[0078] See also Figure 3 The calibration scale plate 231 is provided with a plurality of scales 233, and the layout trajectory of the plurality of scales 233 is arc-shaped, and the layout trajectory is coaxial with the adjustment shaft 22. It should be noted that the provision of a plurality of scales 233 can clearly show the deflection direction of the clamping jaws 21 during the lifting process of the clamping mechanism 20, thereby adjusting the raising or lowering of the calibration platform 11, and thus facilitating the adjustment of the two pipes to the alignment position, that is, making the calibration pointer 232 point to the preset position.

[0079] In this embodiment, the preset position on the calibration scale plate 231 is the middle scale of the plurality of scales 233. When the calibration pointer 232 points to the middle scale, the calibration pointer 232 is located in a vertical position, and the axis of the clamping jaw 21 is in a horizontal position.

[0080] Figure 5 , Figure 6 and Figure 7 yes Figure 1 Schematic diagram of the leveling principle of the pipeline butt leveling device.

[0081] See also Figure 5 , Figure 6 and Figure 7 In actual application, the butt ends 3 of the two pipes 1 to be butted are generally suspended in the air, so that the butt ends 3 can swing vertically relative to the support point 2. Therefore, after the two clamping claws 21 of the clamping mechanism 20 are tightly clamped on the butt ends 3 of the pipe 1, the butt ends 3 can swing vertically relative to the support point 2 by lifting and lowering the calibration platform 11. Figure 5 , Figure 6 shown.

[0082] At the same time, since the clamping jaw 21 can rotate with the adjusting shaft 22, when the clamping jaw 21 drives the butt end 3 to rise and fall, due to the swing of the butt end 3, the clamping jaw 21 can also swing vertically relative to the calibration platform 11 with the butt end 3, thereby changing the angle of the axis of the butt end 3 relative to the calibration platform 11, such as Figure 5 , Figure 6 shown.

[0083] In addition, since the clamping jaws 21 of the two clamping mechanisms 20 are coaxially arranged in the initial position, when the observation piece 23 shows leveling, the clamping jaws 21 of the two clamping mechanisms 20 are in a coaxial state, so that the axes of the two butt ends 3 clamped by the clamping jaws 21 are also located on the same straight line, such as Figure 7 As shown, the leveling of the two pipes 1 to be connected is achieved.

[0084] Therefore, when the pipe docking and leveling device of the present application is used, the pipe docking and leveling device is first placed directly below the two pipes 1 to be docked, the calibration platform 11 is raised to a certain height by the power member 13, and the screw rod 32 is rotated to drive the two clamping jaws 21 to move relative to each other, so as to clamp the outer peripheral side of the pipe 1, and the two clamping mechanisms 20 respectively clamp the docking ends 3 of the two pipes 1 to be docked. At this time, the clamping jaws 21 of the clamping mechanism 20 are coaxial with the pipe 1, and under the limiting action of the two clamping jaws 21, the axes of the two pipes 1 are located in the same plane, thereby completing the preliminary leveling action of the two pipes 1.

[0085] After the clamping jaws 21 clamp the pipes 1 to limit the position, the axes of the two pipes 1 are in the same plane, but the axes of the two pipes 1 may not be in the same straight line. And this state can be displayed from the observation member 23. For example, when the axes of the two pipes 1 are not in the same straight line, the calibration pointer 232 on at least one of the two clamping mechanisms 20 does not point to the middle scale of the calibration scale plate 231. If the axes of the two pipes 1 are in the same straight line, the calibration pointers 232 of the two clamping mechanisms 20 both point to the middle scale of the calibration scale plate 231.

[0086] When the axes of the two pipelines 1 are not in the same straight line, the calibration platform 11 is driven to rise and fall by the power member 13, and the direction of the calibration pointer 232 is observed during the lifting process. When both calibration pointers 232 point to the middle scale of the calibration scale plate 231, the leveling process is completed.

[0087] Therefore, the pipe docking and leveling device of the present application only needs to clamp the pipe 1 to be docked on two clamping mechanisms 20, lift the calibration platform 11, and observe whether the observation piece 23 is in the leveling position, so as to determine whether the two pipes 1 are leveled, thereby avoiding the problem of switching back and forth between the lifting and adjusting action and the level ruler detection action in the prior art, and simplifying the entire adjustment operation process.

[0088] In summary, the two clamping mechanisms 20 are fixed on the calibration platform 11, and the clamping claws 21 of the clamping mechanisms 20 can be clamped on the outer peripheral side of the pipe and can rotate relative to the calibration platform 11, so that during the lifting process of the calibration platform 11, the butt end of the pipe is driven to swing or rotate, thereby achieving leveling and alignment of the two pipes.

[0089] At the same time, since the observation piece 23 is connected to the clamping jaw 21, the operator can intuitively see the leveling state of the two pipes through the observation piece 23. When the observation piece 23 shows leveling, the leveling process is completed, thereby simplifying the leveling process of pipe docking.
