Description

Technical Field

[0001] The utility model relates to the technical field of pipeline pressure-bearing detection equipment, in particular to a detection device for pipeline pressure-bearing equipment. Background Art

[0002] With the development of industrialization, pipelines can be seen everywhere in our daily life, such as water supply and drainage pipelines, heating pipelines, gas supply pipelines, long-distance oil transportation pipelines, agricultural irrigation pipelines, hydraulic engineering pipelines, and special pipelines for industrial production, etc. Measuring parameters such as the pressure-bearing capacity and anti-bending property of pipelines is of great significance for determining the usage environment of pipelines, and this requires the use of pipeline pressure-bearing detection equipment.

[0003] When using pipeline pressure-bearing detection equipment to detect the pressure-bearing capacity of pipelines, it is first necessary to use a clamping mechanism to clamp and fix the pipelines. Since a large load needs to be applied to the pipelines during detection, high requirements are imposed on the fixing effect of the clamping mechanism. Some existing clamping mechanisms use two mutually approaching clamping plates to externally clamp the pipelines, making the pipelines stable through two stress points. However, due to the need to apply a large load to the pipelines and the small number of stress points, the clamping stability is still not good. At the same time, the two stress points will bear a large force, so the force distributed on each stress point is large, which is likely to cause deformation of the pipe orifice and easily affect the detection results. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides the following technical solution: A detection device for pipeline pressure-bearing equipment, including a detector, on the surface of which a stabilizing mechanism is provided. The stabilizing mechanism includes a moving component. A moving component is provided on the surface of the detector. Clamping components are installed at both mobile ends of the moving component. The clamping component includes a connecting plate. The mobile end of the moving component is installed with a connecting plate. A first motor is installed on the surface of the connecting plate. A square pipe is connected to the surface of the connecting plate. The output end of the first motor penetrates through the connecting plate and is connected with a meshing rod. The output end of the first motor is rotatably connected to the connecting plate. The meshing rod is arranged inside the square pipe. A plurality of clamping components penetrating through it are slidably connected to the surface of the square pipe. The meshing surfaces of the plurality of clamping components are all meshed with the meshing rod. The clamping ends of the clamping components extend to the outside of the square pipe.

[0005] As an improvement of the above technical solution, the clamping component includes a meshing plate. A meshing plate penetrating through it is slidably connected to the surface of the square pipe. The meshing plate is meshed with the meshing rod. One end of the meshing plate is threadedly connected with a threaded rod. One end of the threaded rod is rotatably connected to a clamping plate. The meshing plate is slidably connected to a guide rod through a mounting block. One end of the guide rod is connected to the clamping plate.

[0006] As an improvement of the above technical solution, a limiting strip is arranged on the surface of the meshing plate, and the meshing plate is slidably connected with the square pipe through the limiting strip.

[0007] As an improvement of the above technical solution, a plurality of through holes are formed in the surface of the square pipe, the through holes are aligned with the guide rods, and the through holes are adapted to the guide rods.

[0008] As an improvement of the above technical solution, the moving assembly includes a second motor, the second motor is installed on the surface of the detector, a slide rail is installed on the surface of the detector, the output end of the second motor penetrates through the detector and is connected with a bidirectional lead screw, the output end of the second motor is rotatably connected with the detector, two sliders are slidably connected inside the slide rail, the bidirectional lead screw penetrates through the two sliders and is threadedly connected with the two sliders.

[0009] The beneficial effects of the present utility model:

[0010] The inner clamping of the pipeline is realized by using a plurality of expanded clamping components.

At the same time, since there are more clamping points, the force borne by each clamping point is smaller, thereby reducing the risk of local stress concentration of the object and reducing the influence on the detection result caused by clamping.

Detailed Description of the Invention

[0017] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Please refer to Figures 1-5 , the present utility model provides a technical solution: a pipeline pressure-bearing equipment detection device, including a detector 1, a stabilizing mechanism 2 is arranged on the surface of the detector 1, the stabilizing mechanism 2 includes a moving component 22, a moving component 22 is arranged on the surface of the detector 1, clamping components 21 are installed at both mobile ends of the moving component 22, the clamping component 21 includes a connecting plate 211, the mobile end of the moving component 22 is installed with a connecting plate 211, a first motor 213 is installed on the surface of the connecting plate 211, a square tube 212 is connected to the surface of the connecting plate 211, the output end of the first motor 213 penetrates through the connecting plate 211 and is connected with an engaging rod 214, the output end of the first motor 213 is rotatably connected with the connecting plate 211, the engaging rod 214 is arranged inside the square tube 212, and a plurality of clamping members 215 penetrating through the square tube 212 are slidably connected to the surface of the square tube 212, the engaging surfaces of the plurality of clamping members 215 are all engaged with the engaging rod 214, and the clamping ends of the clamping members 215 extend to the outside of the square tube 212.

[0019] In this implementation scheme, first start the moving component 22 to make the two clamping components 21 approach each other. When the clamping member 215 enters the inside of the pipe orifice, start the first motor 213, so as to drive the engaging rod 214 to rotate, and then drive the plurality of clamping members 215 to expand outwards, and use the plurality of expanded clamping members 215 to clamp the pipe internally. Since this mechanism can act on multiple clamping points on the inner wall of the pipe during clamping, the clamping stability of the pipe is improved. At the same time, since there are more clamping points, the force borne by each clamping point is smaller, thus reducing the risk of local stress concentration of the object and reducing the influence on the detection result caused by clamping.

[0020] Specifically, the clamping member 215 includes an engaging plate 2151, an engaging plate 2151 penetrating through the square tube 212 is slidably connected to the surface of the square tube 212, the engaging plate 2151 is engaged with the engaging rod 214, one end of the engaging plate 2151 is threadedly connected with a threaded rod 2152, one end of the threaded rod 2152 is rotatably connected with a clamping plate 2153, the engaging plate 2151 is slidably connected with a guide rod 2154 through a mounting block, and one end of the guide rod 2154 is connected with the clamping plate 2153.

[0021] In this embodiment, by rotating the threaded rod 2152 and cooperating with the guide rod 2154, the user can move a single clamping plate 2153, thereby adjusting the length of a single clamping member 215. As a result, multiple clamping plates 2153 can move independently, improving the clamping adaptability of the clamping assembly 21. Therefore, this mechanism can clamp special-shaped pipes.

[0022] Specifically, a limiting strip 2155 is provided on the surface of the meshing plate 2151, and the meshing plate 2151 is slidably connected to the square pipe 212 through the limiting strip 2155.

[0023] In this embodiment, the meshing plate 2151 and the limiting strip 2155 jointly expand and slide on the surface of the square pipe 212. Under the limiting action of the limiting strip 2155, an additional guiding and limiting effect can be exerted on the meshing plate 2151, thereby improving the stability of the meshing plate 2151 when it moves.

[0024] Specifically, a number of through holes 2156 are provided on the surface of the square pipe 212. The through holes 2156 are aligned with the guide rod 2154 and are adapted to the guide rod 2154.

[0025] In this embodiment, by providing the through holes 2156 corresponding to the guide rod 2154, when the clamping plate 2153 moves, the guide rod 2154 can penetrate the through holes 2156 and enter the interior of the square pipe 212, thereby increasing the adjustment range of the clamping plate 2153.

[0026] Specifically, the moving assembly 22 includes a second motor 221. The second motor 221 is installed on the surface of the detector 1. A slide rail 224 is installed on the surface of the detector 1. The output end of the second motor 221 penetrates the detector 1 and is connected to a bidirectional lead screw 222.

The bidirectional lead screw 222 penetrates the two sliders 223 and is threadedly connected to the two sliders 223.

[0027] In this embodiment, by starting the second motor 221, the bidirectional lead screw 222 can be driven to rotate, and then the two sliders 223 can be driven to approach or separate, and further the two clamping assemblies 21 can be made to approach or separate.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
