Description

Technical Field

[0001] The utility model relates to the technical field of pipeline detection, and more specifically, it relates to a portable pipeline size measuring device which is convenient for positioning. Background Art

[0002] To avoid size problems during on-site installation, which may lead to abnormal installation, delay the on-site construction period, and cause some unnecessary losses, it is necessary to measure the size of each pipeline before leaving the factory to ensure that the size is within the tolerance range. Therefore, a measuring device is needed.

[0003] As retrieved, the existing related patent: CN209588902U discloses a size measuring device for large pipelines. In this prior art, a light-emitting device is fixedly connected to a support rod, which can accurately locate the pipeline flange holes. The light emitted by the light-emitting device just passes through the center point of the pipeline end face, facilitating the measurement of the pipeline, saving time and effort.

[0004] However, the following problems exist when using this prior art: The prior art uses a four-hole positioning mechanism execution part to position the inner wall of the flange hole to fix the measuring device. However, when measuring pipelines of different sizes, the operation range of the hole positioning mechanism execution part in the prior art is limited and can only be installed within pipelines of specific sizes, and it is impossible to install and measure within pipelines of various sizes, reducing the use effect and practicality of this measuring device. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the present utility model is to provide a portable pipeline size measuring device which is convenient for positioning and can fit the inner walls of pipelines of different sizes, further improving the use effect and practicality of the device.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A portable pipeline size measuring device which is convenient for positioning, includes an installation column. Four mounting plates arranged in a circumferential array are fixedly connected to the outer surface of the installation column. An adjusting plate is provided on the side of the mounting plate away from the installation column. An arc-shaped support plate is provided on the side of the adjusting plate away from the mounting plate. The outer surface of the arc-shaped support plate fits the inner wall of the pipeline. A first contraction cavity is formed in the mounting plate. The side of the adjusting plate close to the mounting plate slides through and into the first contraction cavity and slides within the first contraction cavity. A control component is provided on the installation column.

[0008] The present utility model is further provided as: An infrared detection device is provided on the side of the installation column.

Specific implementation manner

[0023] Please refer to Figures 1-4 , the present utility model provides the following technical solutions:

[0024] Specifically, it refers to a portable and easy-to-position pipeline size measuring device, including a mounting post 1. An infrared detection device 2 is provided on the side of the mounting post 1. The infrared detection device 2 is a publicly disclosed technology in the existing patent: CN209588902U, and will not be elaborated here. When the mounting post 1 is installed in the pipeline, the infrared detection device can measure the pipeline size.

[0025] Specifically, four mounting plates 3 arranged in a circumferential array are fixedly connected to the outer surface of the mounting post 1. An adjusting plate 4 is provided on the side of the mounting plate 3 away from the mounting post 1. An arc-shaped support plate 5 is provided on the side of the adjusting plate 4 away from the mounting plate 3. The outer surface of the arc-shaped support plate 5 is attached to the inner wall of the pipeline. A first contraction cavity 6 is opened in the mounting plate 3. The side of the adjusting plate 4 close to the mounting plate 3 slides through and into the first contraction cavity 6 and slides in the first contraction cavity 6. Therefore, the adjusting plate 4 can slide on the mounting plate 3. When the device needs to be placed in pipelines of different sizes for measurement, only need to control the adjusting plate 4 to slide in the first contraction cavity 6, so that the distance of the arc-shaped support plate 5 can be adjusted, making the arc-shaped support plate 5 fit the inner walls of pipelines of different sizes, further improving the use effect and practicability of the device.

[0026] Specifically, a fixing screw rod 7 is fixedly installed on the side of the installation column 1 facing away from the infrared detection device 2. A threaded sleeve 8 is sleeved on the outer surface of the fixing screw rod 7 in a threaded manner. A rotating sleeve 9 is rotatably sleeved on the outer surface of the threaded sleeve 8. Four first hinge seats 10 are fixedly connected to the outer surfaces of the four sides of the rotating sleeve 9. A communication sliding groove 12 communicating with the first contraction cavity 6 is formed on the outer surface of the mounting plate 3 facing the fixing screw rod 7. A second hinge seat 13 is fixedly connected to the surface of the adjusting plate 4 close to the communication sliding groove 12. The other side of the second hinge seat 13 extends out of the outer surface of the mounting plate 3 through the communication sliding groove 12 and slides in the communication sliding groove 12. A rotating plate 11 is hinged between the second hinge seat 13 and the first hinge seat 10;

[0027] When it is necessary to place the measuring device in the pipeline, by rotating the exposed side of the threaded sleeve 8 outside the rotating sleeve 9, the threaded sleeve 8 is displaced under the drive of the thread of the fixing screw rod 7, so that the threaded sleeve 8 is displaced towards the side close to the installation column 1, and then the rotating tube 9 forms a thrust on the rotating plate 11, so that the rotating plate 11 pushes the adjusting plate 4 to displace out of the first contraction cavity 6, and the arc-shaped support plate 5 presses against the inner wall of the pipeline, so that the measuring device is fixed in the pipeline. At the same time, by using the above method of synchronously displacing the four adjusting plates 4, the infrared detection device 2 can be better positioned at the axis center of the pipeline, the pipeline flange holes can be accurately located, and the light emitted by the infrared detection device 2 just passes through the center point of the pipeline end face, which is convenient for measuring the pipeline, saving time and effort.

[0028] Specifically, a second contraction cavity 14 is formed inside the side of the adjusting plate 4 close to the arc-shaped support plate 5. A contraction rod 15 is fixedly connected to the side of the arc-shaped support plate 5 close to the adjusting plate 4. The other end of the contraction rod 15 slides through and into the second contraction cavity 14. A sliding plate 16 is fixedly connected to the end of the contraction rod 15 located inside the second contraction cavity 14. The sliding plate 16 slides in the second contraction cavity 14. A tension spring 17 is fixedly connected between the sliding plate 16 and the inner wall of the second contraction cavity 14. The tension spring 17 is movably sleeved on the outer surface of the contraction rod 15. When there are irregular and protruding inner walls on the inner wall of the pipeline, the arc-shaped support plate 5 is squeezed by the protruding inner wall of the pipeline, so that the arc-shaped support plate 5 is displaced towards the side close to the adjusting plate 4. At the same time, the contraction rod 15 pushes the sliding plate 16 to slide in the second contraction cavity 14, and the tension spring 17 is stretched. By using this method, the problem that the installation effect of the pipeline size measuring device is affected by the irregular inner wall in the pipeline is avoided as much as possible. At the same time, the length of the protruding part of the inner wall of the pipeline can be judged according to the distance that the contraction rod 15 shrinks into the second contraction cavity 14, further ensuring the effect of pipeline detection.

[0029] The working principle of a portable and easy-to-position pipeline size measuring device provided by the present utility model is as follows: By rotating the side of the threaded sleeve 8 exposed outside the rotating sleeve 9, the threaded sleeve 8 is displaced under the drive of the thread of the fixed screw 7, so that the threaded sleeve 8 is displaced towards the side close to the mounting column 1, thereby the rotating tube 9 forms a thrust on the rotating plate 11, causing the rotating plate 11 to push the adjusting plate 4 to displace out of the first contraction cavity 6, and causing the arc-shaped support plate 5 to squeeze the inner wall of the pipeline, so that the measuring device is fixed in the pipeline.
