Description

Technical Field

[0001] The utility model relates to the technical field of leakage detection, in particular to a hydraulic rod leakage detection device. Background Art

[0002] A hydraulic rod is a mechanical device that uses liquid pressure as a power source. The hydraulic rod consists of a sealed pipe system filled with liquid, usually oil. When liquid is added to the pipe system, due to its incompressibility, when a force is applied on one side, the liquid will transfer this force and transmit it to the other side. The hydraulic pump is used to generate the power of liquid flow and push the liquid into the hydraulic rod. By controlling the operation of the hydraulic pump and valve, the output force of the hydraulic rod can be precisely controlled to meet different working requirements.

[0003] Hydraulic rod oil leakage is one of the common faults of machinery and equipment. During the use of the hydraulic rod, due to the aging of the seal or the long service life of the hydraulic rod, hydraulic rod oil leakage will occur, which will directly affect the mechanical hydraulic power transmission system. The pressure drop of the hydraulic system will cause the equipment to work abnormally and lose power support.

[0004] Therefore, after a hydraulic rod fails, maintenance personnel are required to perform a leak test. The conventional operation is to first place the hydraulic rod on the ground, then connect the oil pipe to the hydraulic rod, turn on the hydraulic press to fill oil into the hydraulic rod, extend the hydraulic rod telescopic rod to the limit, and check whether there is hydraulic oil flowing out of the oil port joint. During the detection process, the hydraulic press applies pressure to the hydraulic rod to push the liquid. During this process, the hydraulic rod will be offset due to mechanical movement, and the hydraulic rod needs to be manually fixed, which is not conducive to the operation of maintenance personnel.

[0005] Based on this, in order to solve the above-mentioned technical defects, a hydraulic rod leakage detection device is now proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] Embodiment 1: A hydraulic rod leakage detection device, such as Figure 1-Figure 2As shown, it includes a base 1, a workbench 2, a fixed block 3, a movable frame 4, a first spring 5 and an auxiliary component. The top of the base 1 is connected to the workbench 2, and the movable frame 4 is symmetrically slidably connected to the workbench 2 front and back. The two movable frames 4 are welded with fixed blocks 3 for clamping the hydraulic rod to be tested on one side close to each other. Two first springs 5 ​​are connected between the fixed block 3 and the workbench 2. The first springs 5 ​​are sleeved on the movable frame 4 on the same side, and the workbench 2 is provided with an auxiliary component.

[0022] like Figure 2 As shown, the auxiliary components include a rotating frame 6 and a sliding column 7. The front bottom side of the workbench 2 is slidably connected to the sliding column 7, the lower side of the movable frame 4 is rotatably connected to the rotating frame 6, and the left sides of the two rotating frames 6 are rotatably connected to the sliding column 7.

[0023] Embodiment 2: Based on Embodiment 1, Figure 1 and Figure 4 As shown, the detection device also includes a sliding frame 10, a second spring 11, a scale 12 and an indicator frame 13. The sliding frame 10 is slidably connected to the workbench 2, two second springs 11 are connected between the sliding frame 10 and the inside of the workbench 2, the indicator frame 13 is welded to the right front part of the sliding frame 10, the scale 12 is fixedly connected to the front side of the workbench 2, and the left side of the indicator frame 13 is sharp and is used to point to the scale on the scale 12.

[0024] like Figure 1 and Figure 3 As shown, it also includes a hydraulic pump 14, an oil guide pipe 15, a through pipe 8 and a collecting box 9. The right side of the workbench 2 is connected with the through pipe 8, and a collecting box 9 for collecting leaked oil is placed on the top of the base 1 below the through pipe 8. A hydraulic pump 14 is installed on the left side of the top of the base 1, and an elastic oil guide pipe 15 is clamped on the rear side of the workbench 2, and the lower end of the oil guide pipe 15 is connected to the hydraulic pump 14.

[0025] First, push the sliding column 7 to the right to push the rotating frame 6 to rotate, so that the rotating frame 6 drives the two movable frames 4 to move outward, and moves the fixed block 3 outward. The first spring 5 is compressed, and the hydraulic rod to be tested is placed on the workbench 2, and then the sliding column 7 is released, so that the fixed block 3 moves inward under the reset action of the first spring 5 to clamp the hydraulic rod, and moves the movable frame 4 inward to reset. The movable frame 4 pushes the rotating frame 6 to rotate in the opposite direction, so that the rotating frame 6 pushes the sliding column 7 to move to the left to reset. After the hydraulic rod is clamped, connect the oil guide pipe 15 to the oil filling port of the hydraulic rod, and then connect the external oil pipe to the hydraulic pump 14. The oil is injected into the hydraulic rod through the oil guide pipe 15 through the hydraulic pump 14, so that the hydraulic rod telescopic rod extends, and the telescopic rod will push the sliding frame 10 to move to the right. The second spring 11 is compressed, and the indicator frame 13 moves with the sliding frame 10. The indicator frame 13 will point to the scale on the scale 12. Through the scale 1 2 can know the extended length of the telescopic rod. The greater the hydraulic pressure, the faster the flow speed of the oil, and the stronger the force that pushes the hydraulic rod to extend and retract. The fixed block 3 clamps the hydraulic rod to ensure the stability of the hydraulic rod during detection, and avoids the displacement of the hydraulic rod position caused by the flow of oil and affects the detection. Observe whether the joint of the hydraulic rod is leaking. If there is oil leakage, the leaked oil will flow through the through pipe 8 to the collection box 9 for storage. After the test, the oil is pumped back by the hydraulic pump 14. The telescopic rod of the hydraulic pump 14 is shortened and reset, and will no longer resist the sliding frame 10. The sliding frame 10 will drive the indicator frame 13 to move to the left and reset under the reset action of the second spring 11. The upper end of the oil guide pipe 15 is removed from the hydraulic rod, and then the sliding column 7 is pushed to move to the right, so that the fixed block 3 moves outward to loosen the clamping of the hydraulic rod, and the hydraulic rod is removed from the workbench 2, and then the sliding column 7 is loosened to reset the fixed block 3 and the sliding column 7. In this way, the leakage detection of the hydraulic rod is completed.
