Description

Technical Field

[0001] The utility model relates to the technical field of pipeline construction, in particular to a precise pipeline alignment tool. Background Art

[0002] In the field of civil engineering pipeline construction, it is often necessary to lay pipelines over a large area. However, in order to ensure that the pipelines are easy to transport and install, the pipelines are divided into different sections and lengths. However, the materials, diameters, etc. of each section of the pipeline may be different.

[0003] When connecting pipelines, not only the connection position should be considered to facilitate construction, but also various issues such as different materials, diameters, thicknesses, etc. The most important thing is that the pipelines should be connected correctly to ensure the use effect.

[0004] Current construction methods:

[0005] ①One worker holds the ends of the two pipes to be connected and aligns them manually, while another worker connects them;

[0006] ② When the pipeline is heavy or cannot be handled by one person, two or more workers will operate the two ends of the pipeline respectively, align them, and then one worker will connect them;

[0007] ③ Place the pipeline on the ground, use stones, sand or wooden wedges to support the low places, and use your feet and body weight to press down the high places to achieve the purpose of alignment;

[0008] ④The connection between pipelines is usually made by welding, heating, sealant, connectors, joint sleeves, etc.

[0009] There are problems with the current construction method:

[0010] ① The workers hold the pipes close to each other, and the alignment accuracy of the pipes is extremely challenging for their personal level, which has a huge impact on the control of construction quality. In addition, the alignment efficiency is not high and deviations are prone to occur;

[0011] ② Multiple people perform alignment operations, which not only wastes labor, but also requires constant adjustment of the alignment positions on both sides, making coordination and operation difficult;

[0012] ③Due to the operations of electric welding, heating and glue injection, workers need to wear protective equipment, which may cause harm to other people around them, thus creating a great safety hazard for the surrounding personnel;

[0013] ④ When pipelines are placed on the ground, high pipelines are prone to be squeezed and cracked or damaged due to uneven weight, and low pipelines are prone to rolling or slipping at the support pad position, which have a serious impact on the alignment and connection of the pipelines;

[0014] ⑤ When the pipeline is not aligned, not only the material consumption increases exponentially, but also during use, the joints are easily damaged because the degree of patency is seriously lower than that of normal pipelines.

[0038] The utility model aims to provide a precise pipeline alignment tool to solve the problems existing in the prior art, with high alignment accuracy, improved construction quality, construction efficiency and construction safety, labor saving and a wide range of applications.

[0039] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] like Figure 1-Figure 6 As shown, this embodiment provides a precise pipeline alignment tool, including two alignment units 1 and a plurality of connection limiters 2, with a simple structure and low manufacturing cost. The alignment units 1 correspond to the pipelines 3 one by one, thereby realizing the clamping and fixing of the two pipelines 3, and facilitating the alignment of the two pipelines 3 in different directions. The alignment unit 1 includes an alignment seat, two pairs of clamping elements and two pairs of locking elements. The clamping elements and the locking elements correspond to each other one by one. The two pairs of clamping elements are movably connected to the alignment seat, and one end of the clamping element can be extended into the alignment seat. The alignment seat is used to place the pipeline 3. The length of the clamping element extending into the alignment seat can be adjusted, thereby being able to adapt to the alignment of the pipelines 3. The alignment of pipelines 3 of different diameters has a wide range of applications. Two pairs of clamping elements are used to clamp pipelines 3 in different directions. The locking element can clamp the clamping element after the adjustment of the clamping element is completed to avoid the movement of the clamping element due to misoperation, which affects the alignment accuracy. A number of limit openings 18 are also provided on the outer wall of the alignment seat. The limit openings 18 correspond to the connecting limit pieces 2 one by one, and the connecting limit pieces 2 can pass through the limit openings 18 on the two alignment units 1 to achieve the alignment of the two alignment units 1, thereby facilitating the alignment of the two pipelines 3, improving the alignment efficiency, and ensuring the alignment quality, reducing the construction difficulty, and avoiding subsequent repeated maintenance. In addition, the operation of this embodiment is simple, which greatly reduces the requirements for personnel quality, saves labor, and avoids injuries to construction workers caused by sparks generated during construction.

[0041] Specifically, the alignment seat includes a bottom support plate 19, a mounting slot plate 11 and a closing cover plate 12. The mounting slot plate 11 is fixed to the upper end of the bottom support plate 19, and one side of the mounting slot plate 11 is open. The mounting slot plate 11 is used to place the pipeline 3, so that the pipeline 3 can be placed through the opening side of the mounting slot plate 11, which is easy to operate. The closing cover plate 12 can be detachably installed on the opening side of the mounting slot plate 11 to achieve the blocking of the opening side of the mounting slot plate 11 to achieve the clamping of the pipeline 3; there are two limit openings 18, and the two limit openings 18 are respectively located at the upper end of the bottom support plate 19 and on both sides of the mounting slot plate 11, which can achieve the limit between the two alignment seats, ensure that all pipelines 3 are coaxial, and then the connection operation can be carried out. This embodiment can ignore the influence of terrain factors during construction, can accurately align, and has a wider range of applications and is more accurate.

[0042] The cross section of the installation slot plate 11 is a square with one side open, and the open side of the installation slot plate 11 faces obliquely upward, which is convenient for placing the pipeline 3 and improves the convenience of operation.

[0043] A buckle 13 is hinged on the two opposite outer walls of the mounting slot plate 11. When the closing cover plate 12 is placed on the open side of the mounting slot plate 11, the buckle 13 can be rotated to buckle on the closing cover plate 12, and the closing cover plate 12 is fixed to the open side of the mounting slot plate 11, so as to achieve a stable connection between the mounting slot plate 11 and the closing cover plate 12, thereby improving the clamping effect on the pipeline 3. The specific structure of the buckle 13 is consistent with the prior art, as long as the closing cover plate 12 can be fixed on the mounting slot plate 11. The overall design is detachable, assemblyable, and replaceable, which saves costs, is easy to carry, can be adjusted to multiple sizes, and has strong applicability.

[0044] The limiting opening 18 is a rectangular hole, and the connecting limiting member 2 is a rectangular plug rod. The connecting limiting member 2 is limited by the limiting opening 18 to achieve alignment of the two alignment units 1.

[0045] Each clamping element includes two relatively arranged movable clamping parts, one end of each movable clamping part is located inside the alignment seat and is used to contact and press the outer wall of the pipeline 3, and the other end of each movable clamping part is located outside the alignment seat, thereby clamping the pipeline 3 through the two relatively arranged movable clamping parts.

[0046] The movable clamping part includes a rotating handle 14, a screw rod 15 and a baffle 16. The rotating handle 14 is fixed to one end of the screw rod 15, and the baffle 16 is fixed to the other end of the screw rod 15. The outer peripheral thread of the screw rod 15 is connected to the threaded hole on the side wall of the alignment seat. The baffle 16 is located in the alignment seat and is used to contact the outer wall of the pipeline 3. The length of the screw rod 15 extending into the alignment seat is adjusted according to the actual diameter of the pipeline 3. By operating the rotating handle 14, the rotating handle 14 drives the screw rod 15 to rotate. While the screw rod 15 rotates, it also moves linearly along the length direction, thereby realizing the distance adjustment between the two relatively arranged baffles 16, and realizing the clamping of pipelines 3 of different diameters. The outer wall of the screw rod 15 is provided with scale lines along the length direction, so that the length of each screw rod 15 extending into the alignment seat can be intuitively seen, and then by making the length of each screw rod 15 extending into the alignment seat consistent, it is ensured that the pipeline 3 is in the center position of the alignment seat, thereby improving the alignment effect and alignment efficiency.

[0047] When the construction is finished, force is applied in the reverse direction to loosen the rotating handle 14, open the buckle 13, and remove the closed cover plate 12. The precision pipeline alignment tool in this embodiment can be removed and used for other constructions.

[0048] The locking element is a latch 17, which is slidably connected to the alignment seat and arranged close to the screw 15. A locking groove is provided on the latch 17 on one side close to the screw 15. The thread of the screw 15 can be embedded in the locking groove to prevent the screw 15 from moving along the length direction, thereby limiting the screw 15 and improving the alignment effect.

The above examples are only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation and application scope.
