Description

Technical Field

[0001] This utility model relates to the field of pipeline welding technology, and specifically to a pipeline welding connector. Background Technology

[0002] Pipelines are devices made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. There are many types of pipelines, among which metal pipelines are widely used. In the process of connecting metal pipelines, butt welding is required. Therefore, construction workers often use pipe welding joints when welding pipelines. A pipe welding joint disclosed in the Chinese utility model patent application has the advantages of making it difficult for weld beads to form inside the joint between the first and second pipelines and making it difficult for the sweeping ball to get stuck at the joint between the first and second pipelines. However, this pipe welding joint has the following disadvantages: (1) It is not convenient for personnel to effectively fix the pipeline during the pipe welding process, which makes it inconvenient for personnel to weld and affects the efficiency of personnel work; (2) It is not convenient for personnel to effectively support the pipeline, which leads to the pipeline accidentally falling off during personnel welding, causing inconvenience for personnel welding.

[0003] To solve the above-mentioned technical problems, Chinese Patent No. CN218396797U discloses a welding pipe connector, which includes a first fixed cylinder, a sliding rod slidably connected to the surface of the first fixed cylinder, a second fixed cylinder slidably connected to one end of the sliding rod, and threaded bolts threadedly connected to both sides of the surface of the first fixed cylinder.

[0004] Although the existing technical solution described above can clamp and weld the two sets of pipes together, after the top joint of the two sets of pipes is welded, the bottom joint cannot be rotated to weld. The pipes still need to be removed and manually flipped by the workers, which increases the workload of the workers and affects the work efficiency. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] Please see Figures 1-4 This utility model provides a technical solution:

[0024] A pipe welding connector includes a base 1, a fixed frame 2 mounted on one end of the top of the base 1, and a handrail 3 mounted on the top of the base 1 at one end of the fixed frame 2. An angle flipping mechanism is mounted on the fixed frame 2, and a docking clamping mechanism is mounted on the angle flipping mechanism. The angle flipping mechanism includes a rotating component and a locking component. The rotating component is used to drive the pipe body on the docking clamping mechanism to rotate, and the locking component is used to fix the angle position after rotation. In use, the device can drive the pipe body on the docking clamping mechanism to rotate around the center through the rotating component, while the locking component can fix the angle position after rotation. The structure is simple and easy to operate, making it convenient for workers to remove the pipe for manual flipping, reducing the workload of workers and ensuring work efficiency.

[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the rotating assembly includes a rotating disk 4 rotatably connected inside the fixed frame 2. A connecting block is installed on one side of the fixed frame 2, and a fixed disk 5 is installed on the other end of the connecting block. A rotating rod is rotatably connected inside the fixed disk 5. One end of the rotating rod extending to the outside of the fixed disk 5 is fixedly connected to one end of the rotating disk 4. A connecting plate 6 is installed on the other side of the rotating disk 4. A movable sleeve 7 is fitted onto the other end of the rotating rod extending to the outside of the fixed disk 5. A handle is installed on one end of the movable sleeve 7. The locking assembly includes multiple sets of positioning holes arranged on one side of the fixed disk 5. Positioning pins 8 are slidably connected inside the positioning holes. The other end of the positioning pins 8 is fixedly connected to one side of the movable sleeve 7. Limiting points are provided inside the movable sleeve 7 on both sides of the rotating rod. The groove and the two ends of the rotating rod are equipped with limiting blocks 9 that are slidably connected to the limiting groove. A spring 10 is installed between the limiting block 9 and the inner wall of the limiting groove. A magnetic block 20 is embedded in the fixed plate 5 at the port of the positioning hole. An iron block that attracts the magnetic block 20 is embedded in one end of the bottom of the movable sleeve 7. First, pull the handle to move the movable sleeve 7. The limiting block 9 also squeezes the spring 10, causing the positioning post 8 to disengage from the inner side of the positioning hole. At this time, the handle can be twisted to rotate the rotating plate 4, the connecting plate 6 and the clamped tube to rotate around the center. After changing the joint position, the handle can be released. The spring 10 drives the movable sleeve 7 to reset. At the same time, the magnetic block 20 and the iron block attract the positioning post 8 and lock it into the inner side of the positioning hole, completing the angle fixation.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a motor is installed at the bottom of the fixed cylinder 13. The drive end of the motor extends to one end inside the fixed cylinder 13 and is equipped with a second threaded rod 17. The second threaded rod 17 is threadedly connected to the movable cylinder 14. Sliding grooves are provided at both ends of the inner wall of the fixed cylinder 13. Sliding blocks 18 that are slidably connected to the sliding grooves are installed at both ends of the movable cylinder 14. Then, when placing the pipes, the two sets of pipes can be placed on the two sets of first clamping plates 11. Then, the motor is started to drive the second threaded rod 17 to rotate, so that the movable cylinder 14 retracts and slides in conjunction with the sliding blocks 18 and the sliding grooves. The second clamping plates 15 on both sides and the first clamping plates 11 come closer together to clamp the pipes.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the docking clamping mechanism includes a set of first clamping plates 11 installed on one side of the connecting plate 6. A slide rod 12 is installed at one end of the first clamping plate 11, and another set of first clamping plates 11 is slidably connected to the other end of the slide rod 12. A fixed cylinder 13 is embedded inside the first clamping plate 11, and a movable cylinder 14 is slidably connected to the inner side of the fixed cylinder 13. A set of second clamping plates 15 is installed at the top of the movable cylinder 14. A first threaded rod 16 is threadedly connected to one end of the second clamping plate 15. A knob is installed at one end of the first threaded rod 16, and another set of second clamping plates 15 is installed at the other end of the first threaded rod 16. A movable rod is installed at the bottom end of the other set of second clamping plates 15. The movable rod is slidably connected to the other set of first clamping plates 11. Furthermore, after clamping, the knob can be held and rotated to rotate the first threaded rod 16, so that the other end of the second clamping plate 15, together with the movable rod and the slide block 18, drives the other set of first clamping plates 11 to move, so as to bring the ports of the two sets of pipes closer together.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, casters 19 are installed at the bottom corners of the base 1, and rubber anti-slip sleeves are fitted on the handles of the armrest 3. The casters 19 are lockable casters. Furthermore, holding the armrest 3 can drive the casters 19 at the bottom of the base 1 to slide, thereby moving the entire device.

[0029] The implementation principle of a pipe welding connector according to an embodiment of this application is as follows: Pulling the handle moves the movable sleeve 7, causing the limiting block 9 to compress the spring 10, thus disengaging the positioning post 8 from the inner side of the positioning hole. At this time, the handle can be twisted in conjunction with the rotating rod to rotate the rotating disk 4, connecting plate 6, and the clamped pipe body around the center, changing the joint position. After changing the joint position, the handle can be released, and the spring 10 drives the movable sleeve 7 to reset. Simultaneously, the magnetic block 20 and the iron block attract the positioning post 8 and engage it inside the positioning hole, completing the angle fixation. When placing pipes, two sets of pipes can be placed on two sets of first clamping plates 11. The start motor drives the second threaded rod 17 to rotate, causing the movable cylinder 14 to retract and slide in conjunction with the sliding block 18 and the sliding groove. The second clamping plates 15 and the first clamping plates 11 on both sides come closer together to clamp the pipe. After clamping, the knob can be held and rotated to drive the first threaded rod 16 to rotate, causing the second clamping plate 15 at the other end to move in conjunction with the movable rod and the sliding block 18 to drive the other set of first clamping plates 11 to move, so that the ends of the two sets of pipes are brought closer together. Holding the handle 3 can drive the universal wheel 19 at the bottom of the base 1 to slide, thereby moving the entire device.

[0030] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
