Description

Technical Field

[0001] This utility model relates to the field of hydraulic system testing technology, specifically to a hydraulic system testing device for a hydraulic lift. Background Technology

[0002] Hydraulic lifts primarily achieve their lifting function through the pressure transmission of hydraulic oil. Their scissor-lift mechanism provides high stability during lifting, while their large working platform and high load-bearing capacity allow for a wider range of high-altitude operations and suitability for multiple people to work simultaneously.

[0003] During the production of hydraulic lifts, the hydraulic system needs to be tested using testing equipment. Currently, with existing portable hydraulic testing devices, residual hydraulic oil in the connecting pipes easily drips from the open test joints after testing, not only contaminating the equipment and the working environment but also potentially damaging the internal electronic components. There is a general lack of an integrated solution that reliably secures the connecting pipes while effectively preventing oil leakage. Utility Model Content

The testing device body 1 includes a mounting block 101, a storage rod 102, and a telescopic groove 103. The mounting block 101 is located on one side of the top of the testing device body 1. The storage rod 102 is located at the middle position on one side of the mounting block 101, allowing the testing connecting pipe 205 to be wound and stored. The telescopic groove 103 is located at the top of the testing device body 1. The positioning block 2 includes an arc-shaped groove 201, an adjusting groove 202, an adjusting block 203, and an adjusting rod 204. 1. The positioning block 2 is located at the top of the positioning block 2. The adjustment groove 202 is located at the rear end of the main body 1 of the testing device and is connected to the telescopic groove 103. The adjustment block 203 is located at the rear end of the positioning block 2. The adjustment rod 204 is located inside the main body 1 of the testing device and passes through the interior of the adjustment block 203. The positioning block 2 can be adjusted by adjusting the adjustment rod 204 and the adjustment block 203, which facilitates the storage and use of the test connection tube 205. The test connection tube 205 is provided on one side of the top of the main body 1 of the testing device. The end of the test connection tube 205 away from the main body 1 of the testing device is provided with a test installation head 206, which facilitates the installation and testing of the testing device.

[0027] Please refer to this carefully. Figure 1 and Figure 3 The bottom of the main body 1 of the testing device is provided with a charging port 104 for charging the main body 1 of the testing device. The bottom of the front end of the main body 1 of the testing device is provided with multiple sets of touch buttons 105. The touch buttons 105 are set into two sets, one set can control the switch with one button and the other set can start the test with one button. The front end of the main body 1 of the testing device is provided with a touch display screen 106. Both sides of the main body 1 of the testing device are provided with grooves 107 to facilitate the picking up of the testing device and make the use of the testing device more convenient.

[0028] Please refer to this carefully. Figure 2 and Figure 3One end of the storage rod 102 is welded to one side of the mounting block 101. The storage rod 102 is fixedly connected to the main body 1 of the testing device via the mounting block 101, thus enabling the storage rod 102 to be installed on the top of the main body 1 of the testing device. The positioning block 2 is movably connected to the main body 1 of the testing device via the telescopic groove 103. The adjusting block 203 is movably connected to the main body 1 of the testing device via the adjusting groove 202, allowing for movable adjustment between the positioning block 2, the adjusting block 203, and the main body 1 of the testing device. The adjusting block 203 is welded to the positioning block 2. The bottom end of the adjusting rod 204 is equipped with a manual adjustment mechanism. The rotating block allows for manual adjustment of the adjusting rod 204. A bearing is located at the top of the adjusting groove 202, and the top of the adjusting rod 204 extends through the bearing. The adjusting rod 204 is rotatably connected to the main body 1 of the testing device via the bearing, making its use more stable. An external thread is located at the top of the outer side of the adjusting rod 204. A threaded hole matching the adjusting rod 204 is located inside the adjusting block 203, providing a limit adjustment effect. This allows the adjusting block 203 to drive the positioning block 2 for lifting and lowering adjustment, facilitating the storage and use of the test connection tube 205.

[0029] Please refer to this carefully. Figure 1 and Figure 2 The test mounting head 206 has a sealing gasket inside and a rotating hole at the bottom inside. The test mounting head 206 is movably connected to the test connecting pipe 205 through the rotating hole, which facilitates testing of the hydraulic system of the test device and the hydraulic lift. Rubber support pads are provided at the four corners of the rear end of the test device body 1 to make the horizontal placement of the device more stable. The test device body 1 consists of a test unit and a battery. The battery can be charged through the charging port 104. This utility model also includes a sealing cap, which can be threaded to the open end of the test mounting head 206 for physical sealing of the test mounting head after the test.

[0030] The main body 1 of the testing device also integrates a testing unit, which includes a pressure sensor fluidly connected to the testing connection pipe 205, a microprocessor for processing the sensor signals, and a battery to power the entire device. The pressure sensor is used to detect the pressure value of the hydraulic system in real time, and its electrical signal is output to the microprocessor. The microprocessor processes and analyzes the collected pressure data and presents the results, such as real-time pressure and peak pressure, on the touch display screen 106 through the drive circuit. The touch button 105 is connected to the microprocessor and is used to perform operations such as powering on, starting the test, and clearing the data.

[0031] Working principle: 1. Testing phase: First, reliably connect the test mounting head 206 to the test point of the hydraulic system of the hydraulic lift. Second, press the touch button 105 to start the device. The pressure sensor inside the main body 1 of the test device begins to collect hydraulic signals and processes the data through the microprocessor. Finally, the real-time pressure value and other key parameters are displayed on the touch screen 106 to complete the performance test of the hydraulic system.

[0032] 2. Storage Phase: After the test, the first step is to remove an independent sealing cap and tighten it at the port of the test mounting head 206. This physical sealing fundamentally prevents the leakage of residual hydraulic oil inside the pipe.

[0033] The second step is to wrap the sealed test connection tube 205 around the outside of the storage rod 102. The third step is to manually rotate the adjusting rod 204 at the bottom. Because the thread of the adjusting rod 204 engages with the threaded hole of the adjusting block 203, the adjusting block 203 will drive the positioning block 2 to move steadily upwards. Finally, the arc-shaped groove 201 at the top of the positioning block 2 will tightly press and fix the coiled test connection tube 205, achieving neat and reliable storage. By using a "sealing first, then fixing" method, the problem of residual oil contaminating the equipment is completely solved, providing good protection and ease of use.
