TECHNICAL FIELD

[0001] The present application relates to the technical field of pipe butt joint, in particular to a pipe butt joint tool. BACKGROUND

[0002] In the part of the system of the marine vessel, the cargo oil system is mainly used, and the pipe is mostly connected in the form of butt joint. Since the cargo oil pipe has a large diameter and the pipe is heavy, the two pipes for butt joint need to be placed on the ground for assembly and positioning. However, since the ground is uneven, it is difficult to ensure that the two pipes are on the same horizontal plane, thereby affecting the installation accuracy of the pipe. Moreover, when welding is performed, since the outside of the pipe is in contact with the ground, the pipe needs to be rotated for welding on the side in contact with the ground, thereby affecting the welding quality of the pipe. Therefore, the pipe butt joint tool is proposed. SUMMARY

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-8 This invention provides a technical solution: a pipe-connecting fixture, comprising two bottom bases 1, each bottom base 1 connected to a pipe support assembly 2, a mounting plate 3 connected to the pipe support assembly 2, and a V-shaped support frame 4 connected to the side of the mounting plate 3 away from the pipe support assembly 2. Two pipes to be connected are placed on the two V-shaped support frames 4 respectively. Two connectors 5 are connected between the two pipe support assemblies 2, and the two connectors 5 are connected to the two pipe support assemblies 2 respectively through hinge seats. A drive assembly 6 is provided at the connection point of the two connectors 5, and a tensioning assembly 7 is provided on the drive assembly 6. The two pipes to be connected are placed on the two V-shaped support frames 4 respectively, and then the drive assembly 6 drives the two driven pulleys 210 to rotate, thereby causing the pipe support assembly 2 to move up and down. This causes the two mounting plates 3 to drive the two V-shaped support frames 4 fixedly connected to them to move up and down, thereby adjusting the two pipes to a suitable height for welding operations.

[0025] The single-unit pipe support assembly 2 includes a first housing 201 mounted on a bottom base 1. A rectangular frame 202 is provided within the inner cavity of the first housing 201. The rectangular frame 202 is connected to a mounting plate 3, and racks 203 are provided on both the left and right inner walls of the rectangular frame 202. A drive gear 204 is also provided within the inner cavity of the first housing 201. A driven gear 205 is meshed with the outer edge of the drive gear 204. Both the drive gear 204 and the driven gear 205 are connected to a connecting shaft 206, and both are connected to the inner cavity of the first housing 201 via the connecting shaft 206. The outer side of 01 is connected to a second box 207. The connecting shaft 206 on the drive gear 204 passes through the first box 201 and extends into the inner cavity of the second box 207. The end of the connecting shaft 206 located in the inner cavity of the second box 207 is connected to a worm gear 208. The outer edge of the second box 207 is meshed with a worm 209. The worm 209 passes through the second box 207 and is connected to a driven pulley 210. In order to improve the stability of the rectangular frame 202 when it moves up and down, the inner cavity of the first box 201 is provided with a guide rail 2011, and the first box 201 is connected to the rectangular frame 202 through the guide rail 2011.

[0026] Specifically, when the driven pulley 210 rotates, it drives the worm 209, which is fixedly connected to it, to rotate. Since the worm 209 meshes with the worm wheel 208, the worm 209 drives the worm wheel 208 to rotate. The worm wheel 208 then drives the second housing 207, which is fixedly connected to it, to rotate. This causes the second housing 207 to drive the driving gear 204 to rotate. Since the driving gear 204 meshes with the driven gear 205, the driving gear 204 drives the driven gear 205 to rotate. At this time, because the driving gear 204... The driven gear 205 meshes with the racks 203 on both sides, so that the driving gear 204 and the driven gear 205 simultaneously drive the two racks 203 to move up and down. The two racks 203 will then drive the rectangular frame 202 fixedly connected to them to move up and down. Since the top of the rectangular frame 202 is connected to the mounting plate 3, the rectangular frame 202 drives the mounting plate 3 to move up and down. The mounting plate 3 will then drive the V-shaped support frame 4 fixedly connected to it to move up and down, thereby adjusting the two pipes to a suitable height to facilitate welding operations.

[0027] The drive assembly 6 includes a first connecting rod 602 connected to two connecting pieces 5. The two connecting pieces 5 are hinged together by the first connecting rod 602. A connecting plate 601 is connected to the bottom end of the first connecting rod 602. A turntable 603 and a drive pulley 604 are connected to the first connecting rod 602. A transmission belt 605 is provided on the outer side of the drive pulley 604. The drive pulley 604 is connected to two driven pulleys 210 respectively through the transmission belt 605. A second connecting rod 606 is connected to the connecting plate 601. A limit wheel 607 is connected to the second connecting rod 606. The limit wheel 607 contacts the transmission belt 605 but is not connected. In order to ensure that the transmission belt 605 and the drive pulley 604 do not detach, the connecting plate 601 and the two bottom bases 1 are in the same plane.

[0028] Specifically, rotating the turntable 603 will cause the first connecting rod 602, which is fixedly connected to it, to rotate. Since the bottom of the first connecting rod 602 is connected to the connecting plate 601 through a coupling, the first connecting rod 602 is prevented from rotating while the connecting plate 601 is rotating. Since the driving pulley 604 is fixedly connected to the first connecting rod 602, the first connecting rod 602 drives the driving pulley 604 to rotate. Since the driving pulley 604 is connected to the two driven pulleys 210 through the transmission belt 605, the driving pulley 604 drives the two driven pulleys 210 to rotate through the transmission belt 605. When it is necessary to adjust the docking angle, the positions of the two pipe support components 2 are adjusted. At this time, since the limiting wheel 607 fixedly connected to the second connecting rod 606 is in contact with the transmission belt 605 but not connected, it is ensured that there is no slippage between the transmission belt 605 and the driving pulley 604.

[0029] The tensioning assembly 7 includes a third connecting rod 701 mounted on the connecting plate 601. Two fixed rods 702 are connected to the third connecting rod 701. Sleeves 703 are mounted on the outer sides of the two fixed rods 702. Locating pins 704 are connected to the sleeves 703, and the sleeves 703 are connected to the fixed rods 702 through the locating pins 704. A tensioning wheel 705 is connected between the two sleeves 703. The tensioning wheel 705 contacts the transmission belt 605 but is not connected. To prevent slippage between the transmission belt 605 and the two driven pulleys 210 when the tensioning wheel 705 is adjusted according to different docking angles, multiple through holes are provided on the two fixed rods 702, and the diameter of the through holes is equal to the diameter of the locating pins 704.

[0030] Specifically, when adjusting the positions of the two pipe support assemblies 2 according to the docking angle, the transmission belt 605 may become loose due to the change in the distance between the two driven pulleys 210, causing slippage between the transmission belt 605 and the driving pulley 604. At this point, simply remove the two locating pins 704 and pull the two sleeves 703 that are movably sleeved on the fixed rod 702. The sleeves 703 will then drive the tensioning wheel 705, connected via a rotating shaft, to move. This ensures that the tensioning wheel 705 keeps the transmission belt 605 always in contact with both sides of the driving pulley 604, preventing the transmission belt 605 from becoming loose. This ensures that the driving pulley 604 can drive the two driven pulleys 210 to rotate via the transmission belt 605, allowing simultaneous driving of the two pipe support assemblies 2. This keeps the two V-shaped support frames 4 at the same height, preventing the two pipes that need to be docked from being unable to maintain the same horizontal plane, which would affect the installation accuracy of the pipes.

[0031] First, place the pipe-connecting fixture on the ground. Then, place the two pipes on the two V-shaped support frames 4 respectively. At this time, rotate the turntable 603, causing the turntable 603 to drive the drive pulley 604 to rotate via the first connecting rod 602. The drive pulley 604 will then drive the two driven pulleys 210 to rotate via the transmission belt 605, thereby causing the worm gear 209 to drive the worm wheel 208 to rotate. When the worm wheel 208 rotates, it drives the drive gear 204 to rotate via the second housing 207. The drive gear 204 will then drive the driven gear 205 to rotate synchronously, thereby causing the rack 203 to drive the rectangular frame 202 to move up and down. The rectangular frame 202 drives the V-shaped support frames 4 to move up and down via the mounting plate 3. Since the two V-shaped support frames 4 move up and down simultaneously, the two pipes are always in a constant position. While on the same horizontal plane, it facilitates welding work for the staff and avoids the inconvenience of welding the side that is close to the ground when welding on the ground. When there is a certain angle between the two pipes that need to be connected, first adjust the angle of the two pipe support components 2 to the two connecting pipes, and then place the two pipes on the two V-shaped support frames 4 respectively. At this time, due to the change in the position of the two pipe support components 2, the distance between the two first boxes 201 changes. At this time, simply remove the two positioning pins 704, and then adjust the relative position of the two sleeves 703 on the two fixed rods 702. While the sleeves 703 drive the tension wheel 705 to move, they make the transmission belt 605 fit against both sides of the drive pulley 604, thereby preventing slippage between the transmission belt 605 and the drive pulley 604.
