Description

Technical Field

[0001] This utility model relates to the field of sampling and testing equipment technology, and in particular to a hydraulic oil timed sampling and testing mechanism. Background Technology

[0002] During the operation of a hydraulic system, the quality of the hydraulic oil plays a crucial role in the system's performance and stability. The hydraulic oil's performance can deteriorate due to factors such as oxidation and contamination during use, which in turn affects the normal operation of the entire hydraulic system. Therefore, it is essential to regularly sample and test the hydraulic oil. Currently, there are many inconveniences in hydraulic oil sampling. Due to the influence of factors such as temperature, pressure, and impurity sedimentation, the quality of hydraulic oil at different depths in the tank may vary. Existing sampling devices are mostly single-function and cannot conveniently sample hydraulic oil at different depths in the tank. This makes it difficult to comprehensively and accurately detect the overall quality of the hydraulic oil in the tank, posing a hidden danger to the safe and stable operation of the hydraulic system. Therefore, to solve this problem, we need to consider designing a hydraulic oil timed sampling and testing mechanism. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic oil timed sampling and testing mechanism. Addressing usage issues, it includes a sampling mechanism for convenient quantitative sampling of hydraulic oil from the tank, and a lifting mechanism that, in conjunction with the sampling mechanism, allows for sampling of hydraulic oil at different depths within the tank, ensuring the accuracy of subsequent testing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A hydraulic oil timed sampling and testing mechanism includes an oil tank body with a detector mounted on its upper end; a sampling mechanism including a piston cylinder fixedly connected to the upper end of the oil tank body, a piston block that can slide up and down inside the piston cylinder, a telescopic rod mounted on the upper end of the piston cylinder, the telescopic end of the telescopic rod being fixedly connected to the upper end of the piston block, an inlet hose and a drain pipe communicating through the inner bottom space of the piston cylinder, and the other end of the drain pipe communicating with the detection port of the detector; and a lifting mechanism for controlling the sampling depth of the hydraulic oil.

[0005] Preferably, a one-way valve is provided in both the inlet hose and the outlet hose, and a vent is provided at the upper end of the piston cylinder.

[0006] Preferably, the lifting mechanism includes a motor installed on the upper end of the oil tank body, a threaded rod rotatably connected to the upper end of the oil tank body, the upper end of the threaded rod penetrating the inner top of the oil tank body and fixedly connected to the output shaft of the motor, a lifting plate threadedly connected to the threaded rod, and the lower end of the liquid inlet hose penetrating the lifting plate and fixedly connected to the lifting plate.

[0007] Preferably, a guide rod is fixedly connected to the upper end of the main body of the oil tank, the guide rod passes through the lifting plate and is slidably connected to the lifting plate.

[0008] Preferably, the telescopic rod is a hydraulic telescopic rod, and the motor is a servo motor that can change the direction of rotation.

[0009] Preferably, an observation window is provided on the front side of the main body of the fuel tank.

[0010] Compared with the prior art, the advantages of this utility model are as follows: A sampling mechanism is installed, which controls the piston block to move up and down by controlling the telescopic rod. Together with the inlet and outlet pipes, it can conveniently and quickly draw a quantitative amount of hydraulic oil from the tank into the testing instrument for testing, ensuring the accuracy of the test results. A lifting mechanism is also installed, which drives the threaded rod to rotate by starting the motor, causing the lifting plate to move up and down along the guide rod. The height of the lower end of the inlet hose can be adjusted to extract hydraulic oil at different depths, effectively ensuring the accurate detection of the overall hydraulic oil and ensuring the safe operation of the hydraulic system.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figures 1-3A hydraulic oil timed sampling and testing mechanism includes an oil tank body 1, with a detector 2 installed at the upper end of the oil tank body 1. This is the prior art, which can detect the hydraulic oil delivered into it. An observation window 13 is provided on the front side of the oil tank body 1, which allows the staff to observe the current sampling depth. The system also includes a sampling mechanism, which comprises a piston cylinder 3 fixedly connected to the upper end of the oil tank body 1. A piston block 4, which can slide up and down, is installed inside the piston cylinder 3. A telescopic rod 5, which is a hydraulic telescopic rod, is installed at the upper end of the piston cylinder 3. The telescopic end of the telescopic rod 5 is fixedly connected to the upper end of the piston block 4. An inlet hose 6 and a drain pipe 7 are connected to the bottom space inside the piston cylinder 3. Both the inlet hose 6 and the drain pipe 7 are equipped with one-way valves. The one-way valve in the inlet hose 6 supplies only the oil tank body 1. The hydraulic oil inside flows unidirectionally into the bottom of the piston cylinder 3. The one-way valve in the drain pipe 7 allows the hydraulic oil at the bottom of the piston cylinder 3 to flow unidirectionally into the detection port of the detector 2. By controlling the telescopic rod 5 to drive the piston block 4 to move up and down, the hydraulic oil in the oil tank body 1 can be drawn into the bottom of the piston cylinder 3 and then transported to the detector 2 for testing. The other end of the drain pipe 7 is connected to the detection port of the detector 2. The piston cylinder 3 has a vent hole 8 at the top, which allows the top space of the piston cylinder 3 to be ventilated. The system also includes a lifting mechanism for controlling the sampling depth of the hydraulic oil. The lifting mechanism includes a motor 9 mounted on the upper end of the tank body 1. The motor 9 is a servo motor that can change the direction of rotation. A threaded rod 10 is rotatably connected to the upper end of the tank body 1. The upper end of the threaded rod 10 passes through the inner top of the tank body 1 and is fixedly connected to the output shaft of the motor 9. A lifting plate 11 is threaded onto the threaded rod 10. A guide rod 12 is fixedly connected to the upper end of the tank body 1. The guide rod 12 passes through the lifting plate 11 and is slidably connected to the lifting plate 11. The lower end of the inlet hose 6 passes through the lifting plate 11 and is fixedly connected to the lifting plate 11. By controlling the motor 9 to drive the lifting plate 11 to move up and down, the height of the lower end of the inlet hose 6 can be adjusted to extract hydraulic oil at different depths.

[0015] In this invention, initially, the piston block 4 inside the piston cylinder 3 is located at the lower end. The telescopic rod 5 is activated, causing the piston block 4 to move upward a specified distance within the piston cylinder 3. This allows hydraulic oil from the tank body 1 to be quantitatively drawn into the bottom of the piston cylinder 3 through the inlet hose 6. Then, the telescopic rod 5 is controlled to move the piston block 4 downward within the piston cylinder 3, allowing the hydraulic oil at the bottom of the piston cylinder 3 to be transported to the detector 2 through the drain pipe 7. This allows the detector 2 to test the sampled hydraulic oil. The entire sampling and testing process is convenient, and the amount of hydraulic oil sampled can be controlled, ensuring the accuracy of the test results.

[0016] When it is necessary to extract hydraulic oil at different depths from the main body 1 of the oil tank, the starter motor 9 drives the threaded rod 10 to rotate, which in turn drives the lifting plate 11 to move up and down along the guide rod 12. As the lifting plate 11 moves up and down, the height of the lower end of the inlet hose 6 is also adjusted accordingly, thereby enabling the extraction and sampling of hydraulic oil at different depths. This ensures accurate detection of the overall hydraulic oil and guarantees the safe operation of the hydraulic system.

[0017] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
