Description

Technical Field

[0001] This utility model relates to the field of pipeline measurement technology, and more specifically to a device for pipeline measurement. Background Technology

[0002] In the construction and operation and maintenance of petrochemical, municipal engineering, energy and power and industrial plants, pipelines are the core facilities for transporting fluids. The accuracy of their installation location is crucial. The elevation, centerline coordinates, slope and other parameters of the pipeline directly affect the fluid dynamics performance, structural safety and the quality of connection with surrounding equipment. Therefore, it is a routine and critical task to measure these geometric parameters quickly and accurately during the installation, acceptance and regular maintenance of pipelines.

[0003] Currently, the measurement of pipeline parameters mainly relies on traditional optical measuring instruments, such as levels and total stations. Levels are primarily used to obtain pipeline elevation data, while total stations can simultaneously determine the three-dimensional coordinates of points. Although these instruments perform well in engineering surveying in open areas, they present the following problems when applied to the specific scenario of pipeline measurement:

[0004] During inspection, the pipeline needs to be fixed. However, due to the circular structure of the pipeline, it is currently impossible to quickly and accurately locate the pipeline. Furthermore, after positioning, the inspection efficiency is currently low. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a device for pipeline measurement to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a device for pipeline measurement, comprising a working base, a central placement plate fixedly connected to the top of the working base, a main positioning mechanism provided on the side of the central placement plate, a synchronizing rod fixedly connected to both sides of the main positioning mechanism, and a secondary positioning mechanism fixedly connected to the sides of the synchronizing rods away from the main positioning mechanism, a pipeline to be tested placed on the top of the central placement plate, and a testing mechanism provided on the top of the pipeline to be tested; the main positioning mechanism includes a servo motor that can provide power, a bidirectional screw fixedly connected to the side of the servo motor, a mirror-symmetrical threaded groove opened on the side of the bidirectional screw, a moving plate threadedly connected to the side of the threaded groove of the bidirectional screw, two moving plates distributed on both sides of the bidirectional screw, a main positioning plate fixedly connected to the top of the bidirectional screw, and a limiting groove adapted to the pipeline to be tested opened on the sides of the bidirectional screw that are close to each other.

[0007] Furthermore, there are three central placement plates, which are distributed at the center and both sides of the top of the working platform. The central placement plate has a main positioning mechanism on its side, and the two central placement plates have a secondary positioning mechanism on their sides.

[0008] Furthermore, a main synchronizing plate is fixedly connected to the bottom end of the movable plate, and a first limiting rod is movably connected inside the main synchronizing plate. A first supporting plate is fixedly connected to both sides of the first limiting rod, and the side of the movable plate is fixedly connected to the side of the synchronizing rod.

[0009] Furthermore, the secondary positioning mechanism includes a synchronization block fixedly connected to the synchronization rod, a secondary positioning plate fixedly connected to the top of the synchronization block, the structure of the secondary positioning plate being the same as that of the main positioning plate, a secondary synchronization plate fixedly connected to the bottom of the synchronization block, a second limiting rod movably connected inside the secondary synchronization plate, and a second support plate fixedly connected to both sides of the second limiting rod.

[0010] Furthermore, the detection mechanism includes two fixed plates for support. One fixed plate has an output motor fixedly connected to the side away from the other fixed plate, and the output motor has a threaded rod fixedly connected to the side of the fixed plate close to the fixed plate. The threaded rod is located between the two fixed plates.

[0011] Furthermore, a movable block is threadedly connected to the side of the threaded rod, an extension plate is fixedly connected to the side of the movable block, and a detector is fixedly connected to the bottom end of the side of the extension plate away from the movable block, with the detector located above the pipeline to be tested.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model is equipped with a servo motor, a bidirectional screw, a moving plate, and a main positioning plate. During testing, the pipeline to be tested is placed above the central placement plate. After placement, the servo motor starts and drives the bidirectional screw to rotate. When the bidirectional screw rotates, the moving plates on both sides move inward synchronously. When the moving plates move, they drive the main positioning plate to move. The two main positioning plates automatically clamp the pipeline to be tested, which can achieve fast and accurate positioning of the pipeline to be tested.

[0014] 2. This utility model includes an output motor, a threaded rod, a moving block, and a detector. After the pipeline to be tested is fixed, the output motor drives the threaded rod to rotate when it starts. The rotation of the threaded rod causes the moving block to move. When the moving block moves, it drives the detector to move through the extension plate. The detector moves from above the pipeline to be tested, and the output motor can control the detector to move back and forth, thereby performing multiple tests. This allows for rapid testing of the pipeline to be tested while ensuring the accuracy of the test. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figure 1 This utility model provides a device for pipeline measurement, including a working base 1, a central placement plate 2 fixedly connected to the top of the working base 1, a main positioning mechanism 3 provided on the side of the central placement plate 2, a synchronizing rod 4 fixedly connected to both sides of the main positioning mechanism 3, and a secondary positioning mechanism 5 fixedly connected to the sides of the synchronizing rod 4 away from the main positioning mechanism 3. A pipeline 6 to be tested is placed on the top of the central placement plate 2, and a testing mechanism 7 is provided on the top of the pipeline 6 to be tested. There are three central placement plates 2, which are distributed in the middle and on both sides of the top of the working base 1. The side of the central placement plate 2 is provided with the main positioning mechanism 3, and the side of the two central placement plates 2 is provided with the secondary positioning mechanism 5.

[0023] In this embodiment, the three center placement plates 2 are respectively provided with a main positioning mechanism 3 and a secondary positioning mechanism 5 on their sides. The three center placement plates 2 can support the pipeline 6 to be tested, while the main positioning mechanism 3 and the secondary positioning mechanism 5 can clamp and position the pipeline 6 to be tested on both sides and the middle, respectively, to ensure the stability of clamping and positioning.

[0024] Reference Figure 2 and Figure 3 The main positioning mechanism 3 includes a servo motor 301 that provides power. A bidirectional screw 302 is fixedly connected to the side of the servo motor 301. The side of the bidirectional screw 302 has mirror-symmetrical threaded grooves. The side of the threaded grooves of the bidirectional screw 302 is threadedly connected to a moving plate 303. Two moving plates 303 are distributed on both sides of the bidirectional screw 302. The top of the bidirectional screw 302 is fixedly connected to a main positioning plate 304. The sides of the bidirectional screw 302 that are close to each other have limiting grooves that are adapted to the pipeline 6 to be tested. The bottom of the moving plate 303 is fixedly connected to a main synchronization plate 305. The inside of the main synchronization plate 305 is movably connected to a first limiting rod 306. The sides of the first limiting rod 306 are fixedly connected to a first support plate 307. The side of the moving plate 303 is fixedly connected to the side of the synchronization rod 4.

[0025] In this embodiment, the bidirectional screw 302 has mirror-symmetrical threaded grooves on its side. Therefore, when the servo motor 301 starts and drives the bidirectional screw 302 to rotate, the two moving plates 303 move inward synchronously. When the moving plates 303 move, they drive the main positioning plate 304 to move inward, thereby moving the main positioning plates 304 closer to each other and fixing the middle part of the pipeline 6 to be tested. When the moving plates 303 move, they drive the main synchronization plate 305 to move on the side of the first limit rod 306, thereby ensuring the stability of the main positioning plate 304 when it moves.

[0026] Reference Figure 2 and Figure 4 The secondary positioning mechanism 5 includes a synchronization block 501 fixedly connected to the synchronization rod 4. A secondary positioning plate 502 is fixedly connected to the top of the synchronization block 501. The structure of the secondary positioning plate 502 is the same as that of the main positioning plate 304. A secondary synchronization plate 503 is fixedly connected to the bottom of the synchronization block 501. A second limiting rod 504 is movably connected inside the secondary synchronization plate 503. A second support plate 505 is fixedly connected to both sides of the second limiting rod 504.

[0027] In this embodiment, when the moving plate 303 moves, it drives the synchronizing block 501 to move synchronously via the synchronizing rod 4. When the synchronizing block 501 moves, it drives the sub-positioning plate 502 above it to move, thereby causing the two sub-positioning plates 502 on both sides to move inward synchronously, thereby fixing both sides of the pipeline 6 to be tested, so that the pipeline 6 to be tested can be fully clamped and positioned.

[0028] Reference Figure 1 and Figure 5 The testing mechanism 7 includes two fixed plates 701 for support. An output motor 702 is fixedly connected to the side of one fixed plate 701 away from the other fixed plate 701. A threaded rod 703 is fixedly connected to the side of the output motor 702 near the fixed plate 701. The threaded rod 703 is located between the two fixed plates 701. A moving block 704 is threadedly connected to the side of the threaded rod 703. An extension plate 705 is fixedly connected to the side of the moving block 704. A testing instrument 706 is fixedly connected to the bottom end of the side of the extension plate 705 away from the moving block 704. The testing instrument 706 is located above the pipeline 6 to be tested.

[0029] In this embodiment, when the output motor 702 starts and drives the threaded rod 703, the moving block 704 moves on the side of the threaded rod 703. When the moving block 704 moves, it drives the detector 706 to move through the extension plate 705. The detector 706 moves above the pipeline 6 to be tested, thereby testing the pipeline 6 to be tested and realizing rapid testing.

[0030] The working principle of this utility model is as follows: During testing, the pipeline to be tested 6 is placed above the three center placement plates 2. After placement, the servo motor 301 is started. When the servo motor 301 is started, it drives the bidirectional screw 302 to rotate. When the bidirectional screw 302 rotates, it causes the two moving plates 303 to move inward synchronously. When the moving plates 303 move, they drive the main positioning plate 304 to move inward, thereby causing the main positioning plates 304 to move closer to each other and fix the middle part of the pipeline to be tested 6.

[0031] When the moving plate 303 moves, it will drive the synchronous rods 4 on both sides to move. When the synchronous rods 4 on both sides move, they will drive the synchronous block 501 to move. When the synchronous block 501 moves, it will drive the sub-positioning plate 502 above it to move, so that the two sub-positioning plates 502 on both sides move inward synchronously, thereby fixing the two sides of the pipeline 6 to be tested.

[0032] After the pipeline 6 to be tested is fixed, the output motor 702 is started. When the output motor 702 is started, it drives the threaded rod 703 to rotate. When the threaded rod 703 rotates, the moving block 704 moves to the side of the threaded rod 703. When the moving block 704 moves, it drives the detector 706 to move through the extension plate 705. The detector 706 moves above the pipeline 6 to be tested, thereby testing the pipeline 6 to be tested.

[0033] After the test is performed, the tester 706 is located on one side of the output motor 702. The servo motor 301 controls the bidirectional screw 302 to reverse, so that the moving plate 303 drives the main positioning plate 304 to move away from each other. At this time, the tested pipeline 6 can be removed and a new pipeline 6 can be placed in.

[0034] In conclusion, the above are merely preferred embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
