Description

Technical Field

[0001] This utility model relates to the field of pipe pressure resistance testing technology, specifically a pipe pressure resistance testing device. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material, widely used in industrial pipelines for petroleum, chemical, medical, food, light industry, and machinery, as well as in mechanical structural components. Additionally, it is lighter in weight while maintaining the same bending and torsional strength, making it widely used in manufacturing mechanical parts and engineering structures. It is also commonly used in furniture and kitchenware. In stainless steel pipe standards, Brinell hardness is the most widely used, often expressed as the diameter of the indentation, which is both intuitive and convenient. However, it is not suitable for pipes made of harder or thinner steel.

[0003] Stainless steel pipes undergo compressive strength testing during processing, necessitating the use of a compressive strength testing device. Typically, this testing equipment requires clamping the steel pipe using a fixing device to ensure stability during testing. However, existing fixing devices can only accommodate pipes of one size, limiting their usability and hindering compatibility with various sizes. Furthermore, testing different pipe surfaces requires loosening the clamping device, rotating the pipe, and then re-clamping it, impacting testing efficiency. Therefore, this paper proposes a pipe compressive strength testing device to address these issues. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The pipe pressure resistance testing device in this embodiment includes a processing table 1, a protective cover 2 installed on the processing table 1, a linear module 6 arranged on the top inner side of the protective cover 2, a detection component 8 arranged on the moving end of the linear module 6, an adjustment component 7 arranged inside the processing table 1, a clamping mechanism 4 arranged on the processing table 1, and a rotating mechanism 5 arranged on the clamping mechanism 4.

[0024] The clamping mechanism 4 includes two movable seats 401 disposed on the processing table 1. A rotating ring 409 is rotatably mounted inside the movable seat 401. A mounting seat 405 is disposed in the middle of the rotating ring 409. Multiple fixed frames 407 arranged in a ring are fixed on the outside of the mounting seat 405. A sliding groove 408 is opened in the fixed frame 407. A slider 404 is slidably mounted in the sliding groove 408. A clamping plate 410 is fixed on one side of the slider 404.

[0025] A first cylinder 406 is fixedly connected to one side of the mounting base 405. A fixed plate 402 is fixedly connected to the output end of the first cylinder 406. A connecting rod 403 is rotatably connected to one side of the slider 404. The other end of the connecting rod 403 is rotatably connected to the fixed plate 402.

[0026] The detection component 8 includes a third cylinder 801 mounted on the moving end of the linear module 6. A pressure testing head 802 is fixed to the output end of the third cylinder 801. By activating the third cylinder 801, the third cylinder 801 drives the pressure testing head 802 to contact the pipe and perform detection.

[0027] The device activates the first cylinder 406, which drives the connecting rod 403 to move. The connecting rod 403 then drives the slider 404 to move within the slide groove 408, thereby moving the slider 404 towards the center. The clamping plate 410 moves synchronously, thus clamping and fixing the pipe.

[0028] The clamping plate 410 has a rubber pad on its inner side to increase the friction when clamping the pipe.

[0029] Meanwhile, the adjustment component 7 includes a threaded rod 701 horizontally disposed inside the processing table 1. The threaded rod 701 is threaded with movable blocks 702 that can move relative to or away from each other. The upper end of the movable blocks 702 is fixed to the movable seat 401. One end of the threaded rod 701 is driven by an external motor. By starting the external motor, the external motor drives the threaded rod 701 to rotate, and then the threaded rod 701 drives the two movable blocks 702 to move relative to each other. Then the movable blocks 702 drive the movable seat 401 to move, and then the fixing frame 407 on the movable seat 401 abuts against both ends of the pipe for positioning and clamping.

[0030] In addition, the support assembly 3 includes a second cylinder 301 located in the middle of the inner side of the processing table 1. The output end of the second cylinder 301 is fixed with a support plate 302. By activating the second cylinder 301, the second cylinder 301 drives the support plate 302 to rise, so that the support plate 302 abuts against the lower end of the pipe, thereby supporting the pipe.

[0031] Please see Figure 1 In this embodiment, the rotating mechanism 5 includes a drive motor 502 and a second gear 503 disposed on the outside of one of the rotating rings 409. The drive motor 502 is mounted on one of the movable seats 401, and the output end of the drive motor 502 is fixed with a first gear 501 that meshes with the second gear 503.

[0032] The device starts the drive motor 502, which drives the first gear 501 to rotate. The first gear 501 meshes with the second gear 503, which in turn drives the rotating ring 409 to rotate, thereby causing the pipe to rotate and thus detecting different surfaces of the pipe.

[0033] The working principle of the above embodiments is as follows:

[0034] By placing the pipe on the support plate 302, and then starting the second cylinder 301, the second cylinder 301 drives the support plate 302 to rise, so that the pipe is located inside the clamping plate 410. Then, by starting the external motor, the external motor drives the threaded rod 701 to rotate, and the threaded rod 701 drives the two moving blocks 702 to move relative to each other. Then, the moving blocks 702 drive the moving seat 401 to move, and then the fixing frame 407 on the moving seat 401 abuts against both ends of the pipe for positioning and clamping.

[0035] Then, by starting the first cylinder 406, the connecting rod 403 is moved, and the connecting rod 403 moves the slider 404 in the slide groove 408, thereby moving the slider 404 towards the center. The clamping plate 410 moves synchronously, thereby clamping and fixing the pipe.

[0036] Then, the third cylinder 801 is activated to drive the pressure testing head 802 to contact the pipe for testing. Then, the first cylinder 406, which is not equipped with the second gear 503 on the outside of the rotating ring 409, is activated. The first cylinder 406 drives the slider 404 on the connecting rod 403 to move, so that the multiple clamping plates 410 are slightly away from the outside of the pipe. Then, the drive motor 502 is activated to drive the first gear 501 to rotate. The first gear 501 meshes with the second gear 503, which in turn drives the rotating ring 409 to rotate, thereby driving the pipe to rotate. Then, the first cylinder 406 again causes the clamping plates 410 to clamp the pipe, thereby testing different sides of the pipe.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
