Description

Technical Field

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

[0002] In the petrochemical industry, with rapid economic development, the demand for oil is increasing, requiring the installation of longer oil pipelines. The quality of oil pipelines determines the safety of oil transportation. Since pipeline quality varies, it is necessary to test the strength and compressive strength of the inner and outer surfaces of the pipelines to ensure the safety performance of the pipelines during production and use, and to ensure that the pipelines can operate smoothly under normal working conditions.

[0003] Existing testing devices only have one station to test the strength of pipelines. For example, the petrochemical machinery pipeline strength testing device disclosed in patent CN209841517U has a single-station structure, which means that after the testing of one pipeline is completed, the machine must be stopped for unloading and loading operations before the testing of the next pipeline can begin. The unloading and loading operations interrupt the continuous testing process, resulting in slow testing speed and the inability to complete the strength testing of a large number of pipelines in a short time, causing the entire production process to stop. This discontinuity affects the testing efficiency.

[0004] Therefore, it is necessary to invent a strength testing device for mechanical pipelines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a strength testing device for mechanical pipelines, in order to solve the problem that in the current technology, only one station is used to test the strength of the pipeline, resulting in a slow testing speed and an inability to complete the strength testing of a large number of pipelines in a short period of time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for mechanical pipelines, comprising a frame, a first testing platform and a second testing platform are arranged on the left and right sides above the frame, a support platform is arranged in the middle above the first and second testing platforms, a pressure sensor is arranged at the bottom of the groove of the support platform, a display is arranged on the front wall of the first and second testing platforms, the pressure sensor is connected to the display via a data connection cable, and a limit mechanism is arranged on the front and rear sides of the support platform.

[0007] Preferably, a crossbeam is provided at the top of the frame, baffles are provided on the left and right sides of the crossbeam, a slide bar is provided between the baffles, a slide plate is provided above the slide bar, and a sliding sleeve is provided on the bottom surface of the slide plate and slides on the slide bar. The baffles serve to limit and protect, restricting the horizontal movement range of the slide plate and preventing the slide plate from exceeding the safety boundary during movement. The combination of the slide bar and the sliding sleeve constitutes a sliding guide mechanism. The slide bar provides a precise track for the horizontal movement of the slide plate, enabling the slide plate to move smoothly and accurately along the direction of the slide bar.

[0008] Preferably, a first cylinder is provided at the center of the top surface of the slide plate, a connecting plate is provided on the bottom surface of one side of the slide plate, a second cylinder is provided on one side of the connecting plate and located on the crossbeam, and the output end of the second cylinder is connected to the connecting plate. When the piston rod of the second cylinder extends or retracts, it can drive the slide plate to slide along the sliding rod, thereby adjusting the pressure plate to switch back and forth between the first detection table and the second detection table.

[0009] Preferably, a pressure plate is provided below the slide plate, and the top surface of the pressure plate is connected to the output end of the first cylinder. Through the extension and retraction movement of the first cylinder, the pressure applied by the pressure plate to the pipeline and the downward speed can be precisely controlled to meet the strength testing requirements of pipelines of different specifications and materials.

[0010] Preferably, the limiting mechanism includes a stand and a drive plate. The stand is bolted to the surfaces of the first and second testing platforms. A third cylinder is mounted above the stand, and the output end of the third cylinder is equipped with a drive plate. The third cylinder is the power source of the limiting mechanism. It drives the drive plate to move up and down through the telescopic movement of its output end. The drive plate, as an intermediate transmission component, transmits the power of the third cylinder to the arc-shaped clamping block, thereby controlling the movement of the arc-shaped clamping block.

[0011] Preferably, movable pins are provided inside the strip grooves at both ends of the drive plate and extend through to the outside of the stand. Two arc-shaped clamping blocks are provided above the drive plate. The movable pins slide in the strip grooves of the drive plate, which plays a guiding and limiting role. It can ensure that the drive plate maintains linear movement during the up and down movement and avoid the drive plate from deviating or shaking.

[0012] Preferably, the side wall of the arc-shaped clamping block is provided with a connecting member, and a connecting rod is hinged to the connecting member. The lower end of the connecting rod is movably installed between itself and the stand and is fixedly installed on the side wall of the stand. The connecting member, the connecting rod, and the connecting pin together constitute a linkage mechanism. When the drive plate moves up and down, the arc-shaped clamping block is driven to move through the guiding action of the movable pin. The linkage mechanism amplifies or changes the direction of movement, so that the arc-shaped clamping block can clamp or release according to a predetermined trajectory.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model, by setting up a first testing platform and a second testing platform and cooperating with a movable pressure plate, allows the pressure plate to flexibly switch positions between the first and second testing platforms. This design greatly improves testing efficiency. After the strength test of one pipe is completed on the first testing platform, there is no need to wait for the lengthy equipment reset or rearrangement. With the simple operation of the second cylinder, the pressure plate can be moved to the second testing platform to test another pipe. This seamless testing method saves a lot of time and labor costs, and is especially suitable for the strength testing of batch pipes, significantly improving production testing efficiency.

[0015] 2. This utility model achieves precise clamping and positioning of the pipeline to be tested through a limiting mechanism. Precise clamping and positioning ensures that when the pressure plate applies pressure to the pipeline, the pressure can be applied evenly and accurately to the pipeline, thereby improving the accuracy and reliability of the pipeline strength test results and avoiding test errors caused by pipeline position deviation.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-6 The strength testing device for mechanical pipelines shown includes a frame 1. A first testing platform 2 and a second testing platform 3 are arranged on the left and right sides above the frame 1. A support platform 13 is arranged in the middle above the first testing platform 2 and the second testing platform 3. A pressure sensor 14 is arranged at the bottom of the groove of the support platform 13. A display 15 is arranged on the front wall of the first testing platform 2 and the second testing platform 3. The pressure sensor 14 and the display 15 are connected by a data connection cable. Limiting mechanisms 16 are arranged on the front and rear sides of the support platform 13.

[0026] In this embodiment, the arrangement of testing platform 2 and testing platform 3 allows the device to prepare and test two pipes simultaneously. While the pipe on testing platform 2 is being tested, the operator can place the next pipe to be tested on testing platform 3. After testing platform 2 is completed, the pressure plate 12 can be quickly moved to testing platform 3 for testing, without waiting for the equipment to be reset or rearranged, greatly shortening the testing time and improving testing efficiency. Furthermore, the pressure sensor 14 and the display 15 are connected via a data cable, enabling real-time transmission and display of pressure data. Operators can record the testing data promptly and analyze it quickly, avoiding the time-consuming manual reading and recording of data required in traditional testing methods, further improving testing efficiency.

[0027] A crossbeam 4 is provided at the top of the frame 1. Baffles 5 are provided on the left and right sides of the crossbeam 4. A slide rod 6 is provided between the baffles 5. A slide plate 7 is provided above the slide rod 6. A sliding sleeve 8 is provided on the bottom surface of the slide plate 7 and slides on the slide rod 6. A first cylinder 9 is provided at the center of the top surface of the slide plate 7. A connecting plate 10 is provided on the bottom surface of one side of the slide plate 7. A second cylinder 11 is provided on one side of the connecting plate 10 and is located on the crossbeam 4. The output end of the second cylinder 11 is connected to the connecting plate 10. A pressure plate 12 is provided below the slide plate 7. The top surface of the pressure plate 12 is connected to the output end of the first cylinder 9.

[0028] In this embodiment, the slide plate 7 is driven by the second cylinder 11 to slide on the slide rod 6, which can quickly and accurately move the pressure plate 12 to different detection positions. The baffles 5 on the left and right sides of the crossbeam 4 play a limiting and protective role, which can limit the range of movement of the slide plate 7 in the horizontal direction. The combination of the slide rod 6 and the sliding sleeve 8 constitutes a precise sliding guide mechanism. The slide rod 6 provides a stable track for the horizontal movement of the slide plate 7, so that the slide plate 7 can move smoothly and accurately along the direction of the slide rod 6, thereby ensuring the positional accuracy of the pressure plate 12 in the horizontal direction. During the movement of the pressure plate 12, there will be no deviation or shaking, ensuring that it can accurately reach the top of the pipe to be detected each time, thus improving the accuracy of detection.

[0029] The limiting mechanism 16 includes a stand 1601 and a drive plate 1602. The stand 1601 is bolted to the table surfaces of the first inspection table 2 and the second inspection table 3. A third cylinder 1603 is arranged above the stand 1601. The output end of the third cylinder 1603 is provided with the drive plate 1602. Movable pins 1604 are arranged inside the strip grooves at both ends of the drive plate 1602 and extend through to the outside of the stand 1601. Two arc-shaped clamping blocks 1605 are arranged above the drive plate 1602. Connecting parts 1606 are arranged on the side walls of the arc-shaped clamping blocks 1605. Connecting rods 1607 are hinged to the connecting parts 1606. A shaft pin 1608 is movably installed between the lower end of the connecting rod 1607 and the stand 1601 and is fixedly installed on the side wall of the stand 1601.

[0030] In this embodiment, the limiting mechanism 16 clamps and releases the pipe through the telescopic movement of the third cylinder 1603. The operator only needs to control the switch of the third cylinder 1603 to easily complete the clamping action. The linkage mechanism composed of the connecting piece 1606, the connecting rod 1607 and the shaft pin 1608 plays a role in stabilizing the transmission. When the drive plate 1602 moves up and down, the linkage mechanism can accurately convert the movement of the drive plate 1602 into the clamping or releasing action of the arc-shaped clamping block 1605, and ensure the smoothness and consistency of the movement of the arc-shaped clamping block 1605. This stable transmission method avoids the problem of insecure clamping or uneven clamping force caused by unstable mechanical transmission.

[0031] Working principle of this utility model:

[0032] Refer to the instruction manual appendix Figure 1-6When using this utility model, firstly, the operator places the first pipe to be tested on the support platform 13 of the first testing platform 2, so that the pipe is approximately in the center of the groove of the support platform 13. Then, the third cylinder 1603 of the limiting mechanism 16 on the first testing platform 2 is activated. The piston rod of the third cylinder 1603 extends, pushing the drive plate 1602 downward. The movable pin 1604 slides in the strip grooves at both ends of the drive plate 1602, which plays a guiding role and ensures that the drive plate 1602 moves linearly. As the drive plate 1602 descends, the arc-shaped clamping block 1605 moves towards the pipe through the transmission of the connecting piece 1606 and the connecting rod 1607, gradually clamping the pipe on the support platform 13. While the pipe on the first testing platform 2 is being limited, the operator can place the second pipe to be tested on the support platform 13 of the second testing platform 3, similarly so that the pipe is approximately in the center of the groove of the support platform 13. The pressure plate 12 is clamped and fixed by the limiting mechanism 16. Then, the second cylinder 11 is activated, and the piston rod of the second cylinder 11 extends. Through the connecting plate 10, the sliding plate 7 slides along the sliding rod 6, so that the pressure plate 12 moves to the top of the clamped pipe on the first detection table 2. During the movement, the baffle 5 plays a limiting and protective role to prevent the sliding plate 7 from exceeding the safety boundary during the movement. At the same time, the combination of the sliding rod 6 and the sliding sleeve 8 ensures that the sliding plate 7 moves smoothly and accurately, ensuring that the pressure plate 12 can accurately reach the detection position. Finally, the first cylinder 9 is activated, and the piston rod of the first cylinder 9 extends, pushing the pressure plate 12 to move downward, applying pressure to the pipe on the first detection table 2. After the pipe is subjected to pressure, it will transmit the pressure to the pressure sensor 14 at the bottom of the groove of the bearing platform 13. The pressure sensor 14 converts the pressure signal into an electrical signal and transmits it to the display 15 in real time through the data connection line to display and record the pressure data at this time.

[0033] After the pipeline on test bench 2 is inspected, cylinder 9 is activated, causing its piston rod to retract and move pressure plate 12 upwards away from the pipeline. Cylinder 11 is then activated, causing slide plate 7 to slide pressure plate 12 along slide rod 6 from above test bench 2 to directly above the pipeline on test bench 3. Similarly, cylinder 9 is activated, causing pressure plate 12 to move downwards and apply pressure to the pipeline on test bench 3 for strength testing. Pressure sensor 14 transmits the pressure signal to display 15 for display. The operator records the relevant pressure data and compares the strength of the two pipelines based on the pressure data recorded on display 15 to determine whether the pipeline meets the quality requirements.

[0034] Based on this design, inspection station 2 and inspection station 3 can carry out inspection operations in an alternating manner. When one inspection station is in the inspection working state, the other inspection station can simultaneously carry out preparatory work such as unloading and loading. This dual-station alternating operation mode enables seamless connection of the inspection process, greatly avoids the idle time caused by the equipment waiting for loading and unloading, significantly improves the overall efficiency of the inspection work, and ensures that the inspection work can be carried out efficiently, orderly and continuously.
