Description

Technical Field

[0001] This utility model belongs to the field of pipeline installation technology, specifically relating to a pipeline centering adjustment device. Background Technology

[0002] Pipe centering devices are key tools used in pipeline installation projects to ensure that the centerline of the pipeline coincides with that of the casing or support structure. Their design and technology need to be continuously innovated to adapt to different scenario requirements.

[0003] Commonly used pipe centering methods include the airbag method and the retaining ring method. The airbag method involves evenly arranging airbags on the outer side of the casing wall, connecting them in parallel via air conduits, and finally converging at a one-way valve connection. The airbags inflate to center the pipe within the casing. The retaining ring method involves placing a retaining ring at the top of the casing wall to restrict pipe movement and ensure the pipe remains centered within the casing.

[0004] Chinese patent CN204611105U discloses a pipe centering and limiting device, which includes a pair of pipe clamp assemblies; the pipe clamp assembly includes a large semi-circular clamp and a small semi-circular clamp, the large semi-circular clamp and the small semi-circular clamp are coaxially arranged, and the small semi-circular clamp is fixed on the upper side of the large semi-circular clamp.

[0005] The aforementioned patent is not widely applicable to the installation of pipes of various sizes, and misalignment can easily occur when fixing the pipe at the end of the sleeve, affecting the pipe installation. Utility Model Content

[0006] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a pipe centering adjustment device to reduce installation misalignment, improve work efficiency, and ensure the reliability and aesthetics of the pipeline system.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] The pipe centering adjustment device of this utility model includes a sleeve, which includes two sets of oppositely arranged arc plates and a fixed plate. The oppositely arranged arc plates are connected by a connecting shaft. The end of the arc plate away from the connecting shaft is fixedly connected to the fixed plate. Positioning holes are spaced apart on the arc plates. Positioning plates are symmetrically arranged inside the sleeve. Positioning rods are provided on the positioning plates and pass through the positioning holes. A slot is opened at one end of the positioning plate and the other end is connected to a connecting plate. A locking platform is provided on the inner side of the connecting plate.

[0009] in:

[0010] The arc plate is semi-circular in shape, and the fixing plate is perpendicular to the arc plate.

[0011] The opposing fixing plates are fixed together by fixing bolts.

[0012] The connecting shafts are interlocking hinges, with one end of the hinge fixed to the end of one of the arc plates and the other end fixed to the end of another arc plate.

[0013] The sleeve has two positioning plates on its upper and lower inner sides, and the two upper positioning plates and the two lower positioning plates are arranged symmetrically at the center.

[0014] The arc plate has two positioning holes at both the upper and lower parts.

[0015] The positioning plate has two positioning rods symmetrically arranged to match the positioning holes.

[0016] The positioning rod is threaded, and a positioning nut is connected to the positioning rod through the positioning hole.

[0017] The card holder can be locked in the card slot.

[0018] The connecting plate is made of elastic plastic.

[0019] The beneficial effects of this utility model are:

[0020] This invention ensures that the pipeline remains in the correct position during installation. The device is simple to manufacture and the raw materials are readily available. It can be made from materials such as steel or polyethylene sleeves on the construction site. By using fixing bolts to assist the positioning plate and connecting plate, the pipeline fits tightly with the positioning plate. Adjusting the connection of the positioning rod and positioning nut restricts the movement of the pipeline. At the same time, it can also ensure that the corresponding model of pipeline is in the center position of the sleeve when passing through structures such as wall panels and this invention, thereby accurately positioning the pipeline in the predetermined position and ensuring the stability and functionality of the pipeline.

[0021] This invention improves positioning accuracy, simplifies operation procedures, and increases construction efficiency. It can be used for centering various types of pipelines, reducing construction errors and instability. Attached Figure Description

[0027] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0028] Example 1

[0029] like Figure 1-4 As shown, the pipe centering adjustment device of this utility model includes a sleeve 1. The sleeve 1 includes two sets of arc plates 101 and a fixing plate 102 arranged opposite to each other. The arc plates 101 are connected by a connecting shaft 2. The end of the arc plate 101 away from the connecting shaft 2 is fixedly connected to the fixing plate 102. Positioning holes 4 are provided on the arc plate 101 at intervals. Positioning plates 5 are symmetrically arranged inside the sleeve 1. Positioning rods 8 are provided on the positioning plates 5 and are arranged through the positioning holes 4. A slot 501 is provided at one end of the positioning plate 5 and a connecting plate 7 is connected to the other end. A locking platform 701 is provided on the inner side of the connecting plate 7.

[0030] The arc plate 101 is semi-circular in shape, and the fixing plate 102 is perpendicular to the arc plate 101.

[0031] The opposing fixing plates 102 are fixed together by fixing bolts 3.

[0032] The connecting shaft 2 is a hinge that is inserted into each other. One end of the hinge is fixed to the end of one of the arc plates 101, and the other end of the hinge is fixed to the end of another arc plate 101.

[0033] Two positioning plates 5 are provided on the upper and lower parts of the inner side of the sleeve 1, and the two positioning plates 5 on the upper part and the two positioning plates 5 on the lower part are respectively arranged in a centrally symmetrical manner.

[0034] The arc plate 101 has two positioning holes 4 on both the upper and lower parts.

[0035] Two positioning rods 8 are symmetrically arranged on the positioning plate 5 to match the positioning holes 4.

[0036] The positioning rod 8 is threaded and passes through the positioning hole 4 to connect to the positioning nut 6.

[0037] Card holder 701 can be inserted into card slot 501.

[0038] The connecting plate 7 is made of elastic plastic. The material of the connecting plate 7 ensures that when fixing different types of pipes, its position can be adjusted within the slot 501, and the slot 701 can prevent the connecting plate 7 from coming out of the slot 501.

[0039] Working principle and process:

[0040] During pipeline construction, the sleeve 1 is first placed at the location where the pipeline will be installed and rotated along the connecting shaft 2, causing the two sets of arc plates 101 and fixing plates 102 to separate to both sides. The two positioning plates 5 are then positioned opposite each other inside the sleeve 1, and positioning rods 8 are inserted into the positioning holes 4. The two positioning plates 5 are then adjusted according to the position where the pipeline will be placed, and the position of the connecting plate 7 in the slot 501 is adjusted according to the diameter of the pipeline, so as to ensure that the pipeline can be accurately fixed between the positioning plates 5. The sleeve 1 is then closed along the connecting shaft 2 and fixed with fixing bolts 3. The positioning nuts 6 are then fixed to all the positioning rods 8 in sequence to ensure that the pipeline is located in the center of the sleeve 1, thus achieving the centered setting of the pipeline.
