Description

Technical Field

[0001] This utility model relates to the field of pipe docking technology, specifically to a multi-size adjustable pipe docking auxiliary device. Background Technology

[0002] Pipeline connection aids are devices used for connecting, accessing, and maintaining pipelines, enabling workers to connect, repair, clean, and inspect pipelines. Pipeline connection aids can be various types of tools, equipment, or machinery used to ensure the accuracy of pipeline connections and prevent misalignment from affecting the quality of the connection.

[0003] Existing pipe connection aids are typically designed for specific pipe specifications. During operation, different aids need to be replaced depending on the pipe size, requiring workers to prepare a large number of different sized aids, which inconveniences them. Existing connection aids also require manual adjustment to align the pipes, which is inconvenient and prone to deviations during fixing, affecting the quality of the pipe connection. Utility Model Content

[0004] The purpose of this invention is to provide a multi-size adjustable pipe docking auxiliary device to solve the problems in the prior art where different sizes of pipes require different docking auxiliary devices and where manual alignment of pipes is required when fixing them.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-size adjustable pipe docking auxiliary device, comprising two mounting plates, each mounting plate having a lower clamping arm fixedly connected to its bottom, each mounting plate having a swing plate hinged to its top, each swing plate having an upper clamping arm fixedly connected to its top, each of the two lower clamping arms and the two upper clamping arms having a guide plate inside, each of the four guide plates having a slider slidably connected inside, and each of the four sliders having two clamping plates on opposite sides. During operation, the upper clamping arm is flipped so that one end of the upper clamping arm fits against the lower clamping arm, at which point the lower clamping arm, the upper clamping arm, and the mounting plate form a positioning cylinder.

[0006] Preferably, the guide plate located inside the upper clamping arm is fixedly connected between the upper clamping arm and the swing plate, and the guide plate located inside the lower clamping arm is fixedly connected between the lower clamping arm and the mounting plate. Both ends of the inner sides of the two sliders are hinged with connecting plates, and the ends of the four connecting plates away from the sliders are respectively hinged to the four clamping plates. During operation, the sliders push the connecting plates, thereby causing the four clamping plates to move simultaneously toward the center of the positioning cylinder to fix the pipe.

[0007] Preferably, two limiting plates are fixedly connected inside the lower clamping arm and the upper clamping arm. Sliding rods are fixedly connected to both ends of the four clamping plates. One end of each of the eight sliding rods passes through the four limiting plates and is slidably connected to the four limiting plates. A transmission block is hinged to the outer end of each of the two sliders that is close to each other. A first threaded rod is threadedly connected inside each of the two transmission blocks. When the first threaded rod rotates, it drives the sliders inside the lower clamping arm and the upper clamping arm to move. At this time, the slider drives the clamping plate to move towards the center of the positioning cylinder through the connecting plate, thereby directly clamping the pipe in the center of the positioning cylinder.

[0008] Preferably, a fixing plate is fixedly connected to one side of the mounting plate, a rotating shaft is rotatably connected inside the fixing plate, a first bevel gear is fixedly connected to one end of the rotating shaft, a second bevel gear is rotatably mounted on one side of the fixing plate, the second bevel gear meshes with the first bevel gear, and a second turntable is fixedly connected to one side of the second bevel gear.

[0009] Preferably, a rotating cylinder is sleeved on the outer side of the end of the rotating shaft away from the first bevel gear. The rotating cylinder is slidably connected to the rotating shaft. Universal joints are fixedly connected to one side of both the rotating cylinder and the first bevel gear. The other ends of the two universal joints are respectively fixedly connected to two first threaded rods.

[0010] Preferably, the ends of the two lower clamping arms away from the mounting plate are hinged with snap-fit ​​plates, and the inner sides of the two snap-fit ​​plates are provided with limiting grooves that are adapted to the lower clamping arms and the upper clamping arms. After the lower clamping arms and the upper clamping arms are attached, they are limited by the limiting grooves.

[0011] Preferably, one of the lower clamping arms has two limiting rods fixedly connected to both ends on one side. One end of each of the two limiting rods passes through one side of the other lower clamping arm and is slidably connected to the other lower clamping arm. A second threaded rod is rotatably installed on one side of one of the lower clamping arms. One end of the second threaded rod passes through the other lower clamping arm and is threadedly connected to the other lower clamping arm. The other end of the second threaded rod is fixedly connected to a first turntable. By rotating the second threaded rod, the two fixed pipes are brought closer together for docking.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this application, the first threaded rod is threadedly connected to the transmission block. By rotating the first threaded rod, the slider pushes the connecting plate to move. The connecting plate drives the four clamping plates to move simultaneously toward the center of the positioning cylinder, thereby fixing the pipe in the center of the positioning cylinder. The pipe does not need to be manually aligned. By adjusting the number of rotations of the first threaded rod, the four clamping plates can position and fix pipes of different sizes inside the positioning cylinder, thus improving the applicability of the device.

[0014] 2. In this application, the swing plate is hinged to the mounting plate, and the snap-fit ​​plate is provided with a limiting groove that matches the lower clamping arm and the upper clamping arm. After the pipeline docking is completed, the limiting between the lower clamping arm and the upper clamping arm can be released through the snap-fit ​​plate, so that the upper clamping arm can be rotated around the hinge of the swing plate and the mounting plate, thereby making it convenient for workers to remove the docking auxiliary device from the outside of the pipeline and improving the removal efficiency of the docking auxiliary device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a multi-size adjustable pipe docking auxiliary device, including two mounting plates 1. The bottom of each mounting plate 1 is fixedly connected to a lower clamping arm 2, and the top of each mounting plate 1 is hinged to a swing plate 4. The top of each swing plate 4 is fixedly connected to an upper clamping arm 5. The interior of each of the two lower clamping arms 2 and the two upper clamping arms 5 is provided with a guide plate 6. The interior of each of the four guide plates 6 is slidably connected to a slider 7. Each of the four sliders 7 is provided with two clamping plates 9 on opposite sides. During operation, the upper clamping arm 5 is flipped so that one end of the upper clamping arm 5 is in contact with the lower clamping arm 2. At this time, the lower clamping arm 2, the upper clamping arm 5 and the mounting plate 1 form a positioning cylinder.

[0022] The guide plate 6 located inside the upper clamping arm 5 is fixedly connected between the upper clamping arm 5 and the swing plate 4. The guide plate 6 located inside the lower clamping arm 2 is fixedly connected between the lower clamping arm 2 and the mounting plate 1. Both ends of the inner side of the two sliders 7 are hinged with connecting plates 8. The ends of the four connecting plates 8 away from the sliders 7 are respectively hinged to the four clamping plates 9. During operation, the sliders 7 push the connecting plates 8, thereby causing the four clamping plates 9 to move simultaneously toward the center of the positioning cylinder to fix the pipe.

[0023] Both the lower clamping arm 2 and the upper clamping arm 5 are fixedly connected to two limiting plates 11. Both ends of the four clamping plates 9 are fixedly connected to sliding rods 10. One end of each of the eight sliding rods 10 passes through the four limiting plates 11 and is slidably connected to the four limiting plates 11. The outer ends of the two sliders 7 that are close to each other are hinged to transmission blocks 12. The two transmission blocks 12 are threadedly connected to the first threaded rod 13. When the first threaded rod 13 rotates, it drives the sliders 7 inside the lower clamping arm 2 and the upper clamping arm 5 to move. At this time, the sliders 7 drive the clamping plates 9 to move towards the center of the positioning cylinder through the connecting plate 8, thereby directly clamping the pipe in the center of the positioning cylinder.

[0024] A fixing plate 15 is fixedly connected to one side of the mounting plate 1. A rotating shaft 16 is rotatably connected inside the fixing plate 15. A first bevel gear 18 is fixedly connected to one end of the rotating shaft 16. A second bevel gear 19 is rotatably mounted on one side of the fixing plate 15. The second bevel gear 19 meshes with the first bevel gear 18. A second turntable is fixedly connected to one side of the second bevel gear 19.

[0025] A rotating cylinder 17 is sleeved on the outer side of the end of the rotating shaft 16 away from the first bevel gear 18. The rotating cylinder 17 is slidably connected to the rotating shaft 16. Universal joints 14 are fixedly connected to one side of both the rotating cylinder 17 and the first bevel gear 18. The other ends of the two universal joints 14 are fixedly connected to the two first threaded rods 13 respectively.

[0026] Two lower clamping arms 2 are hinged to a snap-fit ​​plate 3 at the end away from the mounting plate 1. The inner side of each snap-fit ​​plate 3 is provided with a limiting groove that matches the lower clamping arm 2 and the upper clamping arm 5. After the lower clamping arm 2 and the upper clamping arm 5 are in contact, they are limited by the limiting groove.

[0027] Two limiting rods 20 are fixedly connected to one end of one of the lower clamping arms 2. One end of each limiting rod 20 passes through one side of the other lower clamping arm 2 and is slidably connected to the other lower clamping arm 2. A second threaded rod 21 is rotatably installed on one side of one of the lower clamping arms 2. One end of the second threaded rod 21 passes through the other lower clamping arm 2 and is threadedly connected to the other lower clamping arm 2. The other end of the second threaded rod 21 is fixedly connected to a first turntable 22. By rotating the second threaded rod 21, the two fixed pipes are brought closer together for docking.

[0028] In use, the swing plate 4 and the snap-fit ​​plate 3 are hinged together. Before operation, the worker can rotate the upper clamping arm 5 around the hinge point of the swing plate 4 and the snap-fit ​​plate 3, so that the end of the upper clamping arm 5 away from the swing plate 4 is in contact with the lower clamping arm 2. The snap-fit ​​plate 3 is hinged to the outside of the lower clamping arm 2. At this time, the snap-fit ​​plate 3 can be rotated, and the limiting groove on the inner side of the snap-fit ​​plate 3 limits the end of the lower clamping arm 2 and the upper clamping arm 5 that are in contact. The lower clamping arm 2, the upper clamping arm 5 and the mounting plate 1 form a positioning cylinder. At this time, the worker can place the positioning cylinder on the outside of the pipe to be connected and start the connection work.

[0029] During operation, the worker drives the second bevel gear 19 to rotate via the second turntable. The second bevel gear 19 drives the rotating shaft 16 and the rotating drum 17 to rotate via the first bevel gear 18, thereby causing the universal joints 14 on one side of the first bevel gear 18 and the rotating drum 17 to rotate. The two universal joints 14 drive the two first threaded rods 13 to rotate. The first threaded rods 13 are threadedly connected to the transmission block 12, and the transmission block 12 is hinged to the slider 7. The rotation of the first threaded rods 13 causes the transmission block 12 to move away from the mounting plate 1, thereby pushing the slider 7 to slide inside the guide plate 6. The connecting plate 8 is hinged to the slider 7 and the clamping plate 9 at both ends. When the two sliders 7 move away from the mounting plate 1, they push the clamping plate 9 to move through the connecting plate 8. The sliding rod 10 is fixedly connected to the clamping plate 9 and is slidably connected inside the limiting plate 11, so that the sliding rod 10 limits the clamping plate 9. When the connecting plate 8 pushes the clamping plate 9 to move, the four clamping plates 9 move towards the center of the positioning cylinder at the same time. Pipes of different sizes can be clamped and fixed in the center of the positioning cylinder, which improves the applicability of the pipe docking auxiliary device and the degree of fit when the pipe is docked.

[0030] Then, place the other pipe to be connected in another cylinder and repeat the previous operation to fix it. At this time, the two pipes are clamped in the center of the positioning cylinder and correspond to each other. Then the worker can rotate the first turntable 22, which drives the second threaded rod 21 to rotate. The second threaded rod 21 is threadedly connected to one of the lower clamping arms 2, thereby driving the pipes to move closer to each other for connection through the positioning cylinder.

[0031] After the two pipes are connected, the clamping plate 3 can be rotated to release the restriction on the lower clamping arm 2 and the upper clamping arm 5. At this time, the worker can flip the upper clamping arm 5 so that one end of the lower clamping arm 2 and the upper clamping arm 5 are away from each other, which makes it convenient for the worker to quickly remove the connection auxiliary device after completing the connection work, thus improving work efficiency. When the upper clamping arm 5 is flipped, the transmission block 12 at one end of the slider 7 gradually approaches the mounting plate 1. At this time, the slider 7 drives the universal joint 14 on one side of the upper clamping arm 5 to move through the transmission block 12 and the first threaded rod 13. When the mounting plate 1 is installed, the first threaded rod 13 on one side of the upper clamping arm 5 is close to the rotating shaft 16. The rotating shaft 16 and the rotating cylinder 17 are slidably connected. The transmission block 12 is hinged to the slider 7. The universal joint 14 is an existing mature technology, so it will not be described in detail here. When the upper clamping arm 5 completes the flip, the rotating shaft 16 is completely inserted into the rotating cylinder 17. When the guide plate 6 is gradually inserted into the rotating cylinder 17 through the transmission block 12 and the universal joint 14, the change in the angle between the first threaded rod 13 and the rotating cylinder 17 will not affect the flipping of the upper clamping arm 5.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
