Description

Technical Field

[0001] This utility model relates to the field of pipeline strength testing technology, specifically a pipeline strength testing device for petrochemical machinery. Background Technology

[0002] Petrochemical machinery pipelines typically possess high strength, high pressure resistance, and good corrosion resistance, ensuring long-term stable operation in harsh environments. After pipeline production, strength testing devices are required to test the pipeline's strength. In existing technologies, once the pipeline is placed on the device, its weight makes it inconvenient to adjust its position, resulting in less than ideal ease of use.

[0003] For example, patent publication number CN222212536U specifically describes a strength testing device for petrochemical machinery pipelines, relating to the technical field of testing devices. It includes a support base, with a base at its upper end, a slider fixedly connected to the lower end of the base, the slider slidably connected to the support base, a connecting block fixedly connected to the lower end of the slider, the connecting block contacting the support base, and a fixing plate fixedly connected to the lower right side of the support base. This utility model provides a strength testing device for petrochemical machinery pipelines. By incorporating components such as a movable seat and a limiting frame, it can limit the pipeline according to its diameter, allowing for quick clamping of the pipeline. Furthermore, by incorporating a cylinder, it can drive a pressure plate, pressing down on the pipeline, thus better fitting the pipeline to the limiting frame. This solves the technical problem of inconvenience in limiting pipelines of different specifications when using petrochemical machinery pipeline strength testing devices. Previously, when the pipeline was placed on the device, its weight made it difficult to adjust its position, resulting in less than ideal ease of use. Utility Model Content

[0007] Preferably, the placement seat is arc-shaped and is fixedly mounted on the base, so that the placement seat can accommodate the pipe, thereby facilitating the placement of the pipe.

[0008] Preferably, a plurality of the supporting steel balls are evenly arranged inside the placement groove, and the supporting steel balls partially penetrate the placement groove and extend to the outside, so that the supporting steel balls can be used to support the pipe.

[0009] Preferably, the threaded post matches the threaded hole, and the threaded post is threadedly connected to the rotating sleeve through the threaded hole, so that the rotating sleeve can drive the threaded post to move when it rotates.

[0021] 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.

[0022] Please see Figure 1-3This utility model provides a technical solution: a strength testing device for petrochemical machinery pipelines, including a base 1, a placement mechanism 2 on the top of the base 1, a stabilizing mechanism 4 and a testing device 3 on the top of the placement mechanism 2, the testing device 3 being an ultrasonic hardness tester, capable of non-destructively testing the hardness of the pipeline, and equipped with a cylinder for lifting and lowering, allowing the pipeline to be placed through the placement mechanism 2, and converting sliding friction into rolling friction, reducing frictional force, making the pipeline easier to move, and facilitating the adjustment of the pipeline's position, thereby effectively improving the convenience of use.

[0023] The placement mechanism 2 includes a placement seat 201, which is arc-shaped and fixedly mounted on the base 1 to accommodate the pipe. The top surface of the placement seat 201 has a placement groove 202, inside which multiple support steel balls 203 are movably installed. These support steel balls 203 are evenly distributed within the groove, extending beyond it to the outside, thus supporting the pipe and converting sliding friction into rolling friction, reducing frictional force. A locking plate 204 is located inside the placement seat 201. A rubber pad 206 is fixedly connected to the top surface of the locking plate 204 to increase friction with the support steel balls 203, thereby securing the support steel balls 203. Two threaded posts 205 are fixedly connected to the bottom surface of the locking plate 204. A rotating sleeve 207 is rotatably connected to the bottom of the placement seat 201 via a bearing 208. The sleeve 207 has a threaded hole 209 inside, and a threaded post 205 matches the threaded hole 209. The threaded post 205 is threadedly connected to the rotating sleeve 207 through the threaded hole 209, so that the rotating sleeve 207 can drive the threaded post 205 to move when it rotates. Synchronous pulleys 210 are fixedly connected to both rotating sleeves 207, and a synchronous belt 211 is provided between the two synchronous pulleys 210, so that the two rotating sleeves 207 can rotate synchronously. A driven gear ring 212 is fixedly connected to the bottom end of one rotating sleeve 207. A drive gear 213 is provided on one side of 212. A drive motor 214 is fixedly connected to the bottom end of the drive gear 213. The drive gear 213 meshes with the driven gear ring 212. The output shaft end of the drive motor 214 is connected to the rotating sleeve 207 through the drive gear 213 and the driven gear ring 212, so that the drive motor 214 can drive the rotating sleeve 207 to rotate. A mounting bracket is provided on the drive motor 214. The mounting bracket is fixedly installed on the bottom surface of the placement seat 201, so that the drive motor 214 can be easily fixed.

[0024] Please see Figure 1 and Figure 4The stabilizing mechanism 4 includes a support frame 401, which is detachably connected to the base 1 by bolts, allowing for easy adjustment of the position of the support frame 401 and thus improving installation flexibility. A hydraulic cylinder 402 is fixedly connected to the support frame 401, and a pressure plate 403 is fixedly connected to the end of the output shaft of the hydraulic cylinder 402. A groove 404 is provided on the bottom surface of the pressure plate 403, which can be driven to move down by the hydraulic cylinder 402. The groove 404 fits against the surface of the pipe, so that the pressure plate 403 can press down on the pipe, thus facilitating the fixation of the pipe.

[0025] During operation, the pipe is placed on the placement seat 201 and supported by multiple movable support steel balls 203, which converts sliding friction into rolling friction, reduces friction, makes the pipe easier to move, and facilitates the adjustment of the pipe's position, thereby effectively improving the ease of use.

[0026] After adjustment, the drive motor 214 drives the drive gear 213 to rotate, which in turn drives the driven gear ring 212 to rotate. The driven gear ring 212 rotates simultaneously, causing the two rotating sleeves 207 to rotate synchronously. The rotation of the rotating sleeves 207 drives the threaded post 205 to rise through the threaded hole 209. The movement of the threaded post 205 causes the locking plate 204 to move, so that the rubber pad 206 is pressed tightly against the support steel ball 203, locking the support steel ball 203 and preventing it from moving freely. This converts rolling friction back into sliding friction, increasing friction and thus improving stability.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
