Description

Technical Field

[0001] This utility model relates to the field of pipeline construction technology, and in particular to a fixing device for pipeline connection. Background Technology

[0002] In existing technologies, pipe butt welding is a crucial step before steel pipe welding, and the quality of the butt joint is a guarantee of reliable welding quality. During construction, manual hoists are often used to fix the movable pipe, multiple sections of angle steel are welded to the circumference of one end of the main pipe, and then triangular iron pins are made. Workers then use hammers and other tools to forcefully lock the two ends of the pipe, resulting in high labor intensity and low construction efficiency. Simultaneously, multiple sections of angle steel are welded to the main pipe material, and after welding, oxyacetylene cutting is used. Welding and cutting can easily damage the main material, potentially causing safety and quality hazards.

[0003] Therefore, how to efficiently and conveniently fix the pipes to be connected during pipeline construction is a technical problem that urgently needs to be solved in the existing technology. Utility Model Content

The clamping mechanism includes two clamping claws, which can be driven to move in opposite directions or in opposite directions to clamp and fix or release the pipes to be docked.

[0006] Furthermore, the clamping mechanism also includes a drive assembly, which includes a drive motor mounted on the support platform, a lead screw that is connected to the output end of the drive motor, and two drive blocks that are threadedly engaged with the lead screw. The two clamping claws are correspondingly mounted on the two drive blocks. When the lead screw is driven to rotate, the two drive blocks are driven to move towards or away from each other along the axial direction of the lead screw.

[0007] Furthermore, the clamping mechanism also includes a support assembly, which includes a support plate disposed on a support platform and two bearing seats. The support plate is provided with a mounting groove, and the two bearing seats are detachably fixedly connected to the bottom of the mounting groove. The lead screw is supported on the bearing seats by the bearing rotation.

[0010] Furthermore, the clamping claw includes a clamping portion, which has an arc-shaped structure.

[0011] Furthermore, the inner wall of the clamping part is provided with a rubber pad.

[0012] Furthermore, each of the two gripping claws has a strip-shaped hole on its gripping part.

[0021] like Figure 1-4As shown: The fixing device for pipe docking in this embodiment includes a support platform 1 and a clamping mechanism 2 disposed on the support platform 1. The clamping mechanism 2 includes two clamping claws 6, which can be driven to move towards or away from each other to clamp and fix or release the pipes to be docked. The support platform 1 is generally a plate-shaped structure. It clamps the pipes to be docked by driving the movement of the two clamping claws 6. In general, there are two pipes to be docked, one of which is a fixed pipe and the other is a movable pipe. In use, the fixed pipe is placed in the clamping space formed by the two clamping claws 6, and then the movable pipe is hoisted to dock with the fixed pipe. Then, the two clamping claws 6 are driven to clamp the two pipes at the docking point, thereby achieving the clamping and fixing of the pipes to be docked. After the two pipes to be docked are clamped and fixed, they are initially welded and fixed by welding. Then, the two clamping claws 6 are released, and further welding is performed to fix them, thereby completing the pipe docking.

[0022] In this embodiment, the clamping mechanism 2 further includes a drive assembly, which includes a drive motor 3 mounted on the support platform 1, a lead screw 8 connected to the output end of the drive motor 3, and two drive blocks 11 threadedly engaged with the lead screw 8. Two clamping claws 6 are correspondingly mounted on the two drive blocks 11. When the lead screw 8 is driven to rotate, the two drive blocks 11 are driven to move towards or away from each other along the axial direction of the lead screw 8. The drive blocks 11 have through holes for the lead screw 8 to pass through, and the lead screw 8 is threadedly engaged with the drive blocks 11. Two external threads with opposite directions are provided on the lead screw 8 corresponding to the travel distance of the two drive blocks 11. Thus, by rotating the drive motor 3 forward or backward, the two drive blocks 11 can move towards or away from each other along the axial direction of the lead screw 8, resulting in a simple and reliable overall structure.

[0023] In this embodiment, the clamping mechanism 2 further includes a support assembly, which includes a support plate 9 disposed on the support platform 1 and two bearing seats 5. The support plate 9 has a mounting groove, and the two bearing seats 5 are detachably fixedly connected to the bottom of the mounting groove. The lead screw 8 is rotatably supported by the bearing seats 5 through bearings. The support plate 9 is placed approximately perpendicular to the support platform 1 and can be fixedly connected to the support platform 1 by welding or bolting. The support plate 9 is positioned along its length or relative to the support platform 1. Figure 1 The upper and lower directions are provided with mounting grooves, which are through slots to facilitate the placement of the drive motor 3 and the lead screw 8, making the overall structure compact. The two bearing seats 5 are along... Figure 1 One bearing housing is positioned at the top and the other at the bottom, thus providing support for the lead screw 8. Generally, the bearing housing 5 is detachably fixed to the bottom of the mounting groove by bolts.

[0024] In this embodiment, the support assembly further includes slide rails 4, mounting bases 7, and sliders 10 disposed on the mounting bases 7 and slidably engaged with the slide rails 4. There are two mounting bases 7, each corresponding to one of two drive blocks 11, which are detachably and fixedly connected. The drive blocks 11 are located between the two sliders 10. Figure 1 As shown, the slide rail 4 is located on the left and right sides of the mounting groove. The slide rail 4 is fixedly connected to the support plate 9. The mounting base 7 and the drive block 11 can be detachably fixedly connected by bolts. The drive block 11 is provided with mounting holes for mounting the mounting base 7. Figure 3 As shown, the drive block 11 is located between the two sliders 10; by setting up the support components, the stability of the movement of the gripper 6 can be improved.

[0025] In this embodiment, the two clamping claws 6 are detachably and fixedly connected to the two mounting bases 7 in a one-to-one correspondence. The clamping claws 6 are provided with connecting parts, which are detachably and fixedly connected to the mounting bases 7 by bolts and nuts.

[0026] In this embodiment, the clamping claw 6 includes a clamping portion 601, which has an arc-shaped structure. The clamping portion 601 is arc-shaped and has a certain width, thereby facilitating the clamping and fixing of the pipe.

[0027] In this embodiment, the inner wall of the clamping part 601 is provided with a rubber pad. By providing the rubber pad, a certain buffering effect can be achieved, which can further reduce the probability of pipe damage.

[0028] In this embodiment, each of the two clamping claws 6 has a slotted hole on its clamping portion 601. The slotted hole is formed along the circumference of the pipe on the clamping portion 601, while the rubber pad is disposed on the inner wall of the clamping portion 601, avoiding the position of the slotted hole. By providing slotted holes on both clamping portions 601, it is convenient for construction personnel to observe whether the pipe is properly connected during pipe connection, and it is also convenient to perform preliminary welding and fixing of the connected pipe through the slotted hole, thereby improving work efficiency.
