Description

Technical Field

[0001] This utility model relates to the field of pipeline laying technology, specifically a pipeline docking and positioning tool. Background Technology

[0002] During the pipeline laying process, the ends of two or more pipelines to be connected are quickly and accurately aligned to facilitate the installation of cables.

[0003] A power cable conduit butt sealing device disclosed in patent publication number CN222981221U includes a base, two lower clamps symmetrically arranged on the left and right sides of the upper end of the base, an upper clamp detachably installed on the upper end of the two lower clamps, and a sealing ring disposed between the two lower clamps and the upper clamp. Two guide blocks penetrating the base are symmetrically fixedly connected to the lower ends of the lower clamps. A guide groove corresponding to the guide blocks is provided on the base. A locking mechanism for butt sealing of two power cable conduits and pre-tightening operation after butt sealing is provided between the base and the two lower clamps. The power cable conduits can be pre-butt-fixed between the lower and upper clamps. When the knob is held and turned, the two lower clamps move synchronously towards the center under the helical transmission action between the double-ended screw and the inner screw seat, thereby pre-tightening the ends of the power cable conduits and the sealing ring. The sealing ring can be combined and fixed between the base, the two lower clamps, and the upper clamp, eliminating the need for manual adjustment of the butt joint state between the power cable conduits and the sealing ring by the operator.

[0004] The aforementioned device can assist in pipe docking and sealing during use. However, in the docking sealing process, after the pipe is moved and docked using clamps to fix it, the stability after docking still needs improvement. To address these issues, a pipe docking positioning fixture is proposed. Utility Model Content

There are two sets of lead screws 12, and the two sets of lead screws 12 are symmetrically arranged. The ends of the two sets of lead screws 12 that are far apart are connected to knobs 13. The moving block 21 is provided with threaded holes 26 that are threadedly engaged with the lead screw 12. By rotating the knobs 13, the lead screw 12 can be rotated, thereby moving the moving block 21 to adjust its position.

[0033] Please see Figure 3 The base 11 is provided with a first moving groove 14 and a second moving groove 15 for the sliding of the moving block 21, so as to facilitate the stable movement of the moving block 21. The base 11 is also provided with mounting holes, so that the base 11 can be fixed at the target position of the pipeline laying using existing mounting bolts or other mounting components.

[0034] Please see Figure 1 An adjustment gap is provided between the ends of the fixed clamp 22 and the movable clamp 23; the adjustment gap allows for the accommodation and fixation of pipes of various sizes between the fixed clamp 22 and the movable clamp 23.

The screw 41 passes through the positioning ring 25 and is fixed to the top of the locking bolt 24. By tightening the bolt 42 at the end, the stress points of the two sets of fixing components 2 are connected into a whole, reducing axial displacement when the pipe is connected.

[0037] Please see Figure 3 The fixing block 31 is fixed to the top of the base 11; it does not affect the connection of the pipe.

[0038] Furthermore, both the fixed clamp 22 and the movable clamp 23 have anti-slip pads connected to their inner walls, improving the stability of the pipe clamping.

[0039] The working principle of this utility model is as follows: the fixed clamp 22 and the movable clamp 23 clamp the pipe.

When the pipe is docked, the end of the pipe passes through the fixed ring 32 and contacts the docking ring 33. When it contacts the docking ring 33, it will squeeze the pressure surface 35. The sealing surface 36 of the sealing ring 34 will squeeze the inner wall of the pipe to enhance the sealing performance. The screw 41 passes through the positioning ring 25 and is fixed to the top of the locking bolt 24. The bolt 42 at the end is tightened to connect the force points of the two sets of fixing parts 2 into a whole, reducing the axial displacement when the pipe is docked.
