Description

Technical Field

[0001] This utility model relates to the field of instrument and meter testing devices, and in particular to an instrument and meter fracturing testing device. Background Technology

[0002] The instrument fracturing test device is a device that evaluates the structural strength, sealing performance and pressure resistance of instruments and other equipment by applying pressure. It verifies the pressure resistance, structural stability and functional reliability of instruments and is widely used in manufacturing, petrochemical, energy and other fields.

[0003] In the prior art, such as Chinese Publication No. CN213209100U, this utility model relates to the technical field of auxiliary equipment for oil extraction. This utility model provides a fracturing equipment instrumentation testing device that accelerates the transfer speed of the equipment and improves the convenience of equipment transfer; it includes a testing host and a sensor, with the sensor electrically connected to the testing host; it also includes a transport component, which has a loading cavity, an inlet / outlet hole at the right end of the loading cavity, a rotating door component fitted inside the inlet / outlet hole, the rotating door component being hinged to the transport component, two sets of walking components at the bottom of the transport component, each set of walking components having a central shaft, rotating hubs at both ends of each central shaft, tires fitted on each rotating hub, suspension components fastened at both ends of each central shaft, the tops of multiple suspension components being connected to the bottom of the transport component, shock absorption components in each suspension component, and multiple leaf springs in each shock absorption component.

[0004] While the above-mentioned solutions have the advantages mentioned above, their disadvantages include the lack of a structure to apply pressure smoothly to the instruments under test. This can easily lead to instantaneous impacts and stress concentrations during the pressure loading process, resulting in uneven local deformation of the instruments under test, premature fatigue or even breakage of the internal structure, distorted test data, and inability to accurately assess the pressure resistance limit and reliability of the instruments. Pressure fluctuations can also cause vibration of the test bench, leading to sensor misjudgment or equipment displacement, reducing test accuracy and repeatability. Furthermore, the lack of a structure to protect the instruments under pressure reduces the testing efficiency and safety of the device. Utility Model Content

[0005] The purpose of this invention is to provide a fracturing testing device for instruments and meters. This invention is designed with a structure that applies pressure smoothly to the instruments and meters to be tested, avoiding instantaneous impacts and stress concentrations during the pressure loading process, preventing uneven local deformation, premature fatigue or even breakage of the internal structure of the instruments under test, and avoiding distortion of test data. The device can accurately assess the compressive strength and reliability of the instruments, and avoids sensor misjudgment or equipment displacement caused by pressure fluctuations and vibration of the testing platform, thereby improving test accuracy and repeatability. A structure is designed to protect the instruments and meters when pressure is applied, improving the testing efficiency and safety of the device.

The plurality of rubber support columns are evenly distributed on the outer surface of the bottom of the base near the four corners, and the plurality of rubber support columns provide stable support for the main body of the device.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] This invention provides a device with a structure that applies pressure smoothly to the instrument under test, avoiding instantaneous impacts and stress concentrations during pressure loading. This prevents uneven local deformation, premature fatigue, or even breakage of the instrument's internal structure. The device can accurately assess the instrument's pressure resistance limit and reliability, and prevents vibrations of the testing platform caused by pressure fluctuations, which could lead to sensor misjudgments or equipment displacement.

The output shaft of the servo motor 2 drives the first gear 3 to rotate, which drives the second gears 6 on both sides and the drive screws 14 on both sides to rotate synchronously. This drives multiple moving blocks 15 to move in opposite directions, and drives multiple rotating arms 17 to rotate relative to the moving blocks 15. Under the limiting guidance of two limit rods 16 in the protective plate 1, the multiple rotating arms 17 rotate, which drives the two connecting seats 18 and the pressure plate 4 to move smoothly down along the limit rods 16. This drives the pressure sensor mounting plate 19 to move smoothly down to contact the instrument in the placement plate 10, and applies pressure to the surface of the instrument, so that the device can smoothly apply pressure to the surface of the instrument to be tested.

[0027] Furthermore, such as Figures 1 to 4As shown, a safety door 20 is rotatably connected to the inner surface of the protective plate 1. An observation window 21 is fixedly embedded in the inner surface of the safety door 20. Two baffles 12 are fixedly installed on the outer surface of the bottom of the pressure plate 4. The two baffles 12 on the pressure plate 4, together with the safety door 20 and the protective plate 1, provide safety protection for the device and the operators.

[0028] Furthermore, such as Figures 1 to 4 As shown, two limiting rods 16 are fixedly installed on the inner surface of the protective plate 1. The two limiting rods 16 are slidably connected to the inner surface of the pressure plate 4. The two limiting rods 16 slide and limit the movement of the pressure plate 4.

[0034] Working principle: The instruments to be tested for fracturing are placed in the placement plate 10. The servo motor 2 is turned on through the control panel 11. The output shaft of the servo motor 2 drives the first gear 3 to rotate, which drives the second gears 6 on both sides and the drive screws 14 on both sides to rotate synchronously. This drives multiple moving blocks 15 to move in opposite directions, and drives multiple rotating arms 17 to rotate relative to the moving blocks 15. Under the limiting guidance of two limit rods 16 in the protective plate 1, the multiple rotating arms 17 rotate, driving the two connecting seats 18 and the pressure plate 4 to move smoothly down along the limit rods 16. This causes the pressure sensor mounting plate 19 to move smoothly down to contact the instruments in the placement plate 10, applying pressure to the surface of the instruments. This allows the device to smoothly apply pressure to the surface of the instruments to be tested. The device can accurately assess the compressive strength and reliability of the instruments, improving the testing accuracy and repeatability. The pressure sensor installed on the pressure sensor mounting plate 19 detects the pressure on the contact surface.
