Description

Technical Field

[0001] The invention relates to the field of pressure gauge detection, in particular to a portable pressure gauge on-site detection device. Background Art

[0002] Pressure gauge is a common pressure measuring instrument, widely used in chemical industry, petroleum, electricity, aerospace, scientific research and other fields. It can intuitively display the pressure changes in various industrial process links, monitor the safety trends in the production process, and gain insight into the formation of conditions in the product or medium process. It builds a rapid and reliable safety guarantee for enterprises and plays an important role in preventing accidents and protecting personal and property safety.

[0003] Nowadays, as enterprises' awareness of production safety continues to increase and their quality management systems gradually improve, enterprises' demand for pressure gauge testing continues to increase, but there are the following problems: the number of pressure gauges used in my country's industrial production is very large, and the use environment is complex and the installation locations are scattered, so the workload of inspection is huge; on the other hand, since pressure gauge inspection requires shutdown and disassembly, it will affect the normal production of the enterprise and bring certain economic losses to the enterprise, so it is often difficult to conduct regular inspections of pressure gauges as required. Therefore, the problem of how to complete on-site inspections of large quantities of pressure gauges in a short period of time needs to be solved urgently.

[0004] In the prior art, there are two main ways for metrology technical institutions to conduct on-site inspections of pressure gauges: one is to use a combination of a pressure standard and a manual air pressure / hydraulic pump to manually create pressure; the other is to use an integrated pressure calibrator, which has its own pressure control system and an electric pressure pump to automatically create pressure. Each of the two methods has its own advantages and disadvantages. The former has a simple structure, a fast pressure-building rate, and low equipment cost, but manual pressure-building will increase the workload of inspectors; the latter has a high degree of automation and can reduce the burden on inspectors to a certain extent, but the pressure-building rate is slow and cannot meet the needs of large-scale pressure gauge inspections. In addition, for pressure gauges of different ranges, the detection equipment on the market is generally divided into two sets of detection equipment: gas (for low pressure) and liquid (for high pressure) due to the different pressure-building media. Therefore, inspectors need to carry at least two sets of equipment to carry out on-site inspections, which does not meet the portability requirements of on-site detection devices. Summary of the invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The portable pressure gauge on-site detection device combines the pneumatic device and the hydraulic device through the air compressor and the gas-liquid boosting principle. The air compressor stores the compressed high-pressure gas and drives the hydraulic pressure through the air pressure. The appropriate detection method is selected according to the type and range of the pressure gauge to be tested. The pneumatic pressure detection port is suitable for pressure gauges with a small range and a small required detection pressure. Otherwise, the hydraulic pressure detection port is used for detection, so that a single pressure source can cover the detection of the full-range pressure gauge, replacing the traditional method of separating the pneumatic pump and the hydraulic pump. The staff does not need to carry two sets of equipment when conducting the detection, which improves the convenience of work and improves work efficiency.

[0018] (2) The portable pressure gauge on-site detection device adopts a micro multi-cylinder air compressor design. It is driven by a motor to enable multiple piston pumps to compress the gas to create pressure at the same time. The high-pressure gas in multiple compression chambers is stored centrally through a collecting pipe, which shortens the pressure-building time before detection and improves work efficiency.

[0019] (3) The portable pressure gauge on-site detection device adopts an integrated design with a compact structure and reasonable layout, which reduces the space occupied by the device and facilitates the carrying and transportation of the device. In addition, the device is equipped with pulleys and handrails for easy mobility. In some specific work scenarios, it can be tested while walking. The disassembled pressure gauge can be quickly reinstalled after the test is completed, shortening the downtime of the production equipment to which the tested pressure gauge belongs, avoiding long-term downtime that affects the normal production of the enterprise and causes certain economic losses to the enterprise.

[0020] (4) The portable pressure gauge on-site detection device uses an industrial camera to capture the detection results, uploads the captured images to the background computer, and uses software to accurately identify the detection results to achieve intelligent detection. During the pressure-generating stage, the motor output drives the gear to rotate, and the gear rotation drives the soft scraper to reciprocate. The soft scraper moves back and forth to clean the dust near the first standard pressure gauge and the second standard pressure gauge, so that the dial maintains good clarity, which is convenient for staff to observe the detection results, ensures that the industrial camera can capture clear detection images, and improves the accuracy of the detection results.

[0037] The surfaces of the gas collecting pipe 11 and the branch pipe 19 are covered with heat-insulating protective materials.

After flowing, the high temperature will be transferred to the surfaces of the gas collecting pipe 11 and the branch pipe 19. The heat-insulating materials are used to cover the surfaces to prevent workers from accidentally touching and getting burned.

[0038] The base 1 is made of lightweight polymer material with high strength and light weight, which improves the overall portability of the device.

[0039] The device is dragged to the work site where batch inspection of pressure gauges is required. A pulley 29 and an armrest 28 are provided on the surface of the base 1. The device is moved to the inspection area by pushing the armrest 28. The base 1 is made of lightweight polymer material, which ensures light weight and high portability while ensuring the supporting effect of the device. The device is pushed to the side of the pressure gauge to be inspected, and the device can be disassembled and inspected immediately to avoid the pressure gauge being in a disassembled state for a long time, which may cause the working equipment to be unable to continue to operate for a long time, shorten the inspection time, and improve work efficiency. Before the detection, the device needs to be pressurized in advance, the power supply is turned on, the battery pack 2 provides power to the motor 3, the motor 3 starts to work, the output end of the motor 3 starts to rotate, the rotating output end of the motor 3 drives the drive shaft 9 to rotate, and the drive shaft 9 drives the top block 10 on the surface to rotate when it rotates. The surface of the top block 10 contacts the piston 8, and the piston 8 is lifted up when it rotates. After the piston 8 is lifted up by the top block 10, it resets under the elastic force of the first spring, completing a cycle of motion. When the output end of the motor 3 drives the drive shaft 9 to rotate continuously, the piston 8 reciprocates in the piston cylinder 7 under the push of the top block 10. When the piston 8 Each time it is reset, the air inlet valve opens and the air outlet valve closes, and the outside air is drawn into the compression chamber 41 through the air inlet pipe 5 on the surface of the compression chamber 41. When the piston 8 is lifted up again by the top block 10, the air in the compression chamber 41 is squeezed, the air in the air inlet valve closes, and the air outlet valve opens. The compressed air enters the gas collecting pipe 11 through the air outlet pipe 6. The high-pressure gas flows to the diverter pipe 19 through the gas collecting pipe 11, and then enters the gas storage tank 12 and the gas storage chamber 16 on the surface of the gas-liquid booster cylinder 14 through the diverter pipe 19, completing the pressure generation and storing the high-pressure gas. The stored high-pressure gas is used to detect the pressure gauge. The device has two detection methods for the pressure gauge, which are determined according to the type and range of the pressure gauge. The first method is to directly install the pressure gauge on the air pressure detection port 20, and to apply pressure to the pressure gauge by releasing the high-pressure gas in the gas storage tank 12, so that the pressure gauge displays the reading. This method is suitable for pressure gauges with small detection pressure and small range. For pressure gauges with large detection range and larger detection pressure, detection is performed through the hydraulic detection port 23. When the air pressure detection port 20 is used for detection, the pressure gauge is first installed on the surface of the air pressure detection port 20, and the first control valve 18 is turned to connect the air storage tank 12 with the air pressure detection port 20. The high-pressure gas in the gas storage tank 12 enters the air pressure detection port 20, and the high-pressure gas loads and pressurizes the pressure gauge to be tested and the first standard pressure gauge 24 on the surface of the air pressure detection port 20 at the same time. By comparing the readings of the pressure gauge to be tested with those of the first standard pressure gauge 24, it is determined whether there is an error in the pressure gauge to be tested, and the test is completed. During the test, the first control valve 18 can be rotated to different deflection angles to control the amount of gas in the gas storage tank 12 entering the air pressure detection port 20 per unit time, thereby changing the output pressure of the air pressure detection port 20, and using different pressures to pressurize the pressure gauge to be tested multiple times to make the test result more accurate.When the hydraulic test port 23 is used for testing, the pressure gauge to be tested is installed on the surface of the hydraulic test port 23, and the second control valve 21 is turned to allow the high-pressure gas in the air storage chamber 16 to enter the gas-liquid booster cylinder 14. The gas-liquid booster cylinder 14 converts the smaller gas pressure into a larger hydraulic pressure, and then pushes the output rod 15 outward through the high hydraulic pressure. The moving output rod 15 drives the pressure rod 22 to move in the hydraulic test port 23, and the pressure gauge to be tested and the second standard pressure gauge 25 are loaded and pressurized at the same time. The readings of the two are compared to determine whether there is an error in the pressure gauge to be tested. By turning the second control valve 21, the output pressure of the gas-liquid booster cylinder 14 reaches the test point quickly and accurately. When testing the pressure gauge, while manually observing the performance reading to determine the error, the industrial camera 27 takes a picture of the test results and uploads the captured image to the background computer. The software in the background computer uses image recognition technology to realize functions such as automatic recognition of test results and automatic reading of test data, making the test more accurate.

[0040] When the driving shaft 9 rotates, it drives the gear 33 on the surface to rotate. The gear 33 meshes with the surface of the rotating wheel 31, and drives the rotating wheel 31 to rotate when rotating. When the rotating wheel 31 rotates, it drives one end of the connecting rod 32 to continuously rotate along the contour of the rotating wheel 31, and the other end drives the soft scraper 30 to reciprocate. When the soft scraper 30 reciprocates, it cleans the dust on the dials of the first standard pressure gauge 24 and the second standard pressure gauge 25 to prevent dust accumulation from affecting the clarity of the dials and affecting the accuracy of the detection results.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
