Examples:

referring to fig. 1, the cooperation is referring to fig. 2 to 6, this application provides a pipeline centering device, including along the circumference direction of pipeline 1 outer wall laminating in proper order a plurality of joint structures placed in the middle on pipeline 1 outer wall, joint structure placed in the middle includes integrated into one piece's fan-shaped locating plate 3 and joint bent plate 4, fan-shaped locating plate 3 installs on the one end of joint bent plate 4, joint bent plate 4 laminating is on pipeline 1's outer wall, and can insert or take out in the clearance between pipeline 1 and the wall body 2, and the degree of depth in the clearance is the same for adjust in the middle pipeline 1 of installing on wall body 2.

The small end of the fan-shaped positioning plate 3 is integrally mounted on the large end of the clamping bent plate 4.

The fan-shaped positioning plate 3 is provided with a first threaded through hole 5 penetrating through two opposite side walls, and one side wall, close to the clamping bent plate 4, of the fan-shaped positioning plate 3 is provided with an arc-shaped groove 6 communicated with the first threaded through hole 5; the arc-shaped groove 6 is internally provided with a matched arc-shaped clamping block 7, and the arc-shaped clamping block 7 is provided with a second threaded through hole 8 penetrating through two opposite side walls; the first threaded through hole 5 corresponds to the second threaded through hole 8, and is in threaded connection with a hexagonal bolt 9; the end of the hexagonal bolt 9 is sleeved with an anti-slip pad 10, and the anti-slip pad 10 is abutted against the surface of the wall body 2 when the centering clamping structure is installed. And, design arc fixture block 7 and hex bolts 9 then be convenient for demolish this device and use.

Further, the diameter of the snap-fit bent plate 4 gradually decreases from one end near the fan-shaped positioning plate 3 toward the other end far from the fan-shaped positioning plate 3. Meanwhile, the thickness of the clamping bent plate 4 gradually decreases from one end close to the fan-shaped locating plate 3 to the other end far away from the fan-shaped locating plate 3.

Further, the outer surface of the snap-fit bent plate 4 is an arc-shaped surface.

In this embodiment, when the pipe 1 is a circular pipe 1, the inner surface of the clamping bending plate 4 is an arc-shaped surface attached to the pipe 1. In other embodiments, when the pipe 1 is a square pipe 1, the inner surface of the clamping bending plate 4 is a folded surface fitting the pipe 1. Moreover, the contact part of the inner surface of the clamping bending plate 4 and the pipeline 1 is preferably made of a material for preventing the pipeline 1 from being scratched, and the clamping bending plate can be well attached. And, the diameter of the internal cavity that is enclosed by a plurality of joint bent plates 4 jointly is unchanged to make it can carry out better laminating with pipeline 1.

Therefore, the device is mainly composed of a structure formed by splitting a conical sleeve which is hollow in the inside and is cylindrical into a plurality of centering clamping structures, and can be used for centering the circular pipeline 1; when the square pipeline 1 is used for centering, the square pipeline 1 can be replaced by a structure formed by splitting a pyramid with a hollow cylinder inside into a plurality of centering clamping structures.

The device has the advantages of simple structure and strong practicability, the design principle is that a plurality of centering clamping structures are utilized to be plugged into gaps between the pipelines 1 and the sleeves on the wall body 2, and when the centering clamping structures are plugged tightly and have the same depth, the centering clamping structures are filled in the same space, so that the central pipeline 1 can be naturally centered. In addition, because the installation of the plurality of centering clamping structures is too firm and difficult to take down in the installation process, the device uses a common thread tightening method to take down the plurality of centering clamping structures, and because the materials of the plurality of centering clamping structures have special requirements and the threads are easy to slide and lose efficacy, the plurality of centering clamping structures are taken out through the rubber hammer; the rubber hammer comprises a hammer head 11, a hammer handle 12, a hexagonal starting head 13 and a protective sleeve 14, wherein the hammer head 11 and the hexagonal starting head 13 are respectively arranged at two ends of the hammer handle 12, the protective sleeve 14 is covered on the hexagonal starting head 13 to play a role in protection, the hexagonal starting head 13 is matched with a hexagonal bolt 9, and an anti-slip pad 10 is abutted on the surface of a wall body 2, so that an arc-shaped clamping block 7, a fan-shaped positioning plate 3 and a clamping bent plate 4 can be driven to loosen by rotating the hexagonal starting head 13 and the hexagonal bolt 9, and the device can be disassembled rapidly. In addition, the hammer 11 is designed into a horseshoe shape and detachably sleeved on the hammer handle 12, so that the hammer can be better installed and replaced, can be used in a turnover manner, reduces the design of threads, reduces the manufacturing cost, and has better stability compared with the triangular structure of the hammer 11 due to the fact that the triangular structure is of a traditional hexagonal shape. The hammer head 11 is smaller, but the gravity center is biased to the hammer head 11 and is symmetrically arranged, so that the hammer head is convenient to hold when the hexagonal starting head 13 is rotated, the weight is increased by adopting metal inside, and the plastic is wrapped outside. The hexagonal bolt 9 is equipped with to hammer handle 12 one end to be furnished with afterbody protective sheath 14, tup 11 are used for beating fan-shaped locating plate 3, and hexagonal plays first 13 cooperation rubber hammer and uses and be used for demolishing the joint structure placed in middle, and afterbody installs hexagonal to play first 13 additional and has accomplished portably under not influencing tup 11 and bolt function, and when using hexagonal to play first 13 simultaneously, symmetrical and have the tup 11 of radian also fine to hold.

In summary, in the pipeline centering device of the application, the structure is simple and the practicability is strong. This device is through in plugging into the clearance between the sleeve pipe on pipeline 1 and the wall body 2 with a plurality of joint structures placed in the middle, and when a plurality of joint structures placed in the middle can cock up simultaneously and the depth of insertion is the same, a plurality of joint structures placed in the middle fill the space the same, then central pipeline 1 is placed in the middle. Simultaneously, install arc fixture block 7 and hexagon bolt 9 on fan-shaped locating plate 3, can very conveniently draw out a plurality of joint structures placed in middle from the clearance to dismantle, the dismouting is more convenient, can repeatedly turn round the use, can be used for the use of different diameter pipelines 1.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
