Description

Technical Field

[0001] This invention belongs to the technical field of pipeline welding auxiliary equipment, specifically relating to a pipeline docking aid and its usage method. Background Technology

[0002] Welding is the primary method of pipe connection during pipeline construction. However, due to manufacturing errors and installation deviations, misalignment at the pipe joints is prone to occur. This misalignment not only affects the appearance quality of the weld but also reduces the strength and sealing of the weld joint, leading to safety hazards such as leaks and ruptures during pipeline use, and even causing major production accidents. Currently, adjusting misaligned pipe joints mainly relies on manual operation, with workers using simple tools such as pry bars and jacks to pry and push the pipes to achieve alignment. This method has three major problems: first, it is labor-intensive and cumbersome; second, it has low work efficiency and a long adjustment cycle; and third, the adjustment accuracy is poor, the effect depends on the worker's experience and skill, and it is easy to scratch the pipe surface, affecting the service life of the pipeline. Therefore, there is an urgent need for a fast, accurate, and easy-to-operate device and method for adjusting misaligned pipe joints. Summary of the Invention

[0003] The purpose of this invention is to provide a pipe docking aid and its usage method to solve the problems mentioned in the background art.

[0004] The objective of this invention is achieved through the following technical solution: a pipe docking aid, comprising a base, wherein the base is formed by bottom surface I and bottom surface II to form a herringbone base, the bottom of the base is provided with symmetrical quick-connect grooves, quick-connect holes are fixedly provided on the quick-connect grooves, and a groove is provided on the side of the base away from the quick-connect grooves.

[0005] The quick-connect slots and grooves on the base are connected to the first connecting component and the second connecting component by connecting pins and pin shafts;

[0006] The soft steel wire rope of the first connecting component cooperates with the locking component of the second connecting component to fix the soft steel wire rope to the fixed pipe and the moving pipe.

[0007] Furthermore, the first connecting component includes a connecting joint, which is installed on the base through a quick-connect groove and a connecting pin. The connecting joint includes a soft steel wire rope and a steel sleeve. The end of the soft steel wire rope is fixed by the steel sleeve, which is embedded and fixed in the connecting hole.

[0008] The base is provided with a T-shaped groove rail connection hole, which passes through the groove;

[0009] The connection joint is positioned in a U-shape, and a through pin hole is fixedly provided on the connection joint.

[0010] Furthermore, the second connecting component includes a T-shaped groove rail, in which a slider is embedded and installed, the slider being slidable along the T-shaped groove rail.

[0011] Furthermore, a lead screw threaded hole is fixedly opened on the slider, and the lead screw threaded hole and the lead screw cooperate to form a lead screw and nut pair transmission structure;

[0012] The T-shaped grooves are symmetrically arranged, and T-shaped grooves are opened on the T-shaped grooves. The lead screw base is fixed to the end face of the T-shaped grooves by bolts and screw holes opened on the end face of the T-shaped grooves. The lead screw base is fixedly provided with a lead screw hole, and the lead screw passes through the lead screw hole and engages with the lead screw thread hole fixedly opened on the slider. A hexagonal column is fixedly provided at the end of the lead screw.

[0013] Furthermore, the slider is provided with a locking assembly, which includes symmetrical trapezoidal baffles formed on the slider. A through pin hole is fixedly opened on the trapezoidal baffle. A cam wrench is connected to the through pin hole by a pin shaft. The cam wrench includes a cam profile surface and a cam pushing surface at a relative position. The cam wrench drives the cam profile surface to rotate, and cooperates with the cam pushing surface to realize the one-way locking / positioning of the soft steel wire rope.

[0014] Furthermore, the bottom plane of the second connecting component conforms to the plane of the base, and a T-shaped groove connecting hole is fixedly provided on the second connecting component.

[0015] Furthermore, the soft steel wire rope forms a hook shape after being fixed by the locking assembly.

[0016] A method for using a pipe connection aid includes the following steps;

[0017] Pass the optical shaft of the lead screw through the upper through hole of the lead screw base, install the bolts, and make the collar abut against the hole wall; install the lower part of the slider into the trapezoidal groove rail, and screw the lead screw into the lead screw thread hole at the bottom of the slider; install the cam wrench and connecting joint, and ensure that the soft steel wire rope is firmly connected to the connecting joint;

[0018] Define the two pipes to be connected as a fixed pipe and a moving pipe respectively. First, place the base on the fixed pipe, select the point where the two pipes are most misaligned, tighten the soft steel wire rope until the base is fixed to one side of the fixed pipe, and then connect the moving pipe through the soft steel wire rope of the connecting joint. Adjust the position of the pipes to make the interface initially aligned.

[0019] The hexagonal column at the top of the lead screw on one side of the moving pipe drives the lead screw to rotate. The lead screw and nut pair drives the slider to slide along the T-shaped groove rail. At the same time, the cam wrench is operated to drive the cam profile surface to rotate. The cam push surface compresses the soft steel wire rope to achieve one-way locking and positioning. Then, the soft steel wire rope pulls and moves the pipe. According to the misalignment of the pipe, fine adjustments are made in the horizontal, vertical and angular directions until the interface is accurately aligned. The adjustment accuracy can reach ±0.1mm.

[0020] After aligning the pipe joints, keep the device locked and perform welding. After welding, rotate the screw to reset the slider, reverse the operation of the cam wrench to unlock the soft steel wire rope, and disconnect the connection between the connector and the pipe to complete the operation.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention offers high adjustment precision by employing a lead screw and nut pair transmission method in conjunction with a cam locking structure. This enables precise adjustment of the pipe's horizontal, vertical, and angular directions, with an accuracy of ±0.1mm, effectively ensuring the alignment quality of the welding joints.

[0023] This invention reduces labor intensity by replacing manual prying operations with mechanical transmission and locking structures. Operators only need to complete equipment assembly, pipeline fixing, and start / stop adjustments, significantly reducing labor intensity and dependence on operational skills.

[0024] This invention has high working efficiency. Compared with the traditional manual adjustment method, this device has a fast adjustment speed and accurate positioning, which can improve the working efficiency by 3-5 times, significantly shorten the construction cycle and reduce the construction cost.

[0025] This invention enables rapid and precise alignment of pipe joints, improves welding quality and construction efficiency, reduces labor intensity, expands the applicability of the equipment, meets the docking requirements of pipes of different specifications, adapts to the misalignment adjustment of welding joints of various pipe specifications, and has strong versatility and practicality.
