Description

Technical Field

[0001] This utility model relates to the field of hydraulic fluid technology, and in particular to a hydraulic fluid viscosity adaptive adjustment device. Background Technology

[0002] For machines such as loaders, excavators, and cranes, the viscosity of the hydraulic fluid in the hydraulic system will change under different working ambient temperatures. This device can ensure that the hydraulic fluid is not too viscous in cold weather, which would cause sluggish operation, and that the system pressure and efficiency are not affected by too low viscosity in hot weather, so that the construction machinery can always maintain good working performance.

[0003] In some existing hydraulic fluid viscosity adaptive adjustment devices, sensors and temperature control systems work together to detect and adjust the viscosity of the hydraulic fluid in real time, while temperature sensors provide synchronous feedback on the oil temperature. The data is then collected and sent to the control unit. When the viscosity deviates from the optimal range, if the viscosity is high due to low oil temperature, the control unit activates the heating element to raise the oil temperature and reduce the viscosity.

[0004] However, in actual use, hydraulic fluid becomes viscous and its fluidity deteriorates in cold weather or low-temperature working environments. If the heating ring cannot reciprocate, the viscosity of the hydraulic fluid will remain high, leading to increased pressure loss and reduced energy transfer efficiency in the hydraulic system. For example, when excavators operate in cold regions, the hydraulic pump needs to consume more energy to overcome the resistance of the high-viscosity hydraulic fluid, which not only increases the engine load but also reduces the response speed and work efficiency of the digging action. To address the above problems, a hydraulic fluid viscosity adaptive adjustment device is proposed. Utility Model Content

[0008] The transmission adjustment mechanism includes a driving bevel gear, which is fixedly connected to the outside of the driving rod. A driven bevel gear is fixedly connected to the top of the hydraulic tank. A transmission rod is fixedly connected to the inside of the driven bevel gear. An eccentric wheel is fixedly connected to the outside of the transmission rod. A drive plate is rotatably connected to the outside of the eccentric wheel.

This allows the docking plug to be adjusted and locked with the heating ring. The heating ring is then energized. When locking the docking plug, the rotating plate is released, causing the return spring to rebound. This allows the positioning rod to lock with the docking plug, thus fixing the docking plug.

Detailed Implementation

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a hydraulic fluid viscosity adaptive adjustment device, comprising a base plate 1. The surface of the base plate 1 is flattened to ensure stable placement of the device. Mounting holes are pre-drilled at the four corners of the base plate 1 for connection to support rods 2. Support rods 2 are fixedly connected to the top four corners of the base plate 1. The two ends of the support rods 2 are precision machined to ensure a tight and secure connection with the base plate 1 and the top plate 3. The top of the support rods 2 is fixedly connected to the top plate 3. A hydraulic tank 4 is fixedly connected inside the top plate 3. The hydraulic tank 4 serves as the core container for storing hydraulic fluid and has good... With good corrosion resistance and pressure resistance, the top plate 3 has an internal mounting hole for mounting the hydraulic tank 4. The top of the hydraulic tank 4 is fixedly connected to a drive mechanism, which includes a motor 5. The motor 5 is a high-performance DC motor, and the power is selected according to the working requirements of the device. The motor 5 is externally fixedly connected to the top of the hydraulic tank 4. The top of the drive rod 8 is externally fixedly connected to the drive end of the motor 5. The bottom of the drive mechanism is fixedly connected to the drive rod 8. The drive rod 8 is made of solid metal rod with good strength and wear resistance. The drive rod 8 is externally fixedly connected to a transmission adjustment mechanism.

[0034] The transmission adjustment mechanism includes a drive bevel gear 12, which is precision machined and heat-treated to have good tooth surface hardness and wear resistance. The module of the drive bevel gear 12 is designed according to the transmission ratio and torque requirements. The drive bevel gear 12 is externally fixedly connected to the outside of the drive rod 8. The top of the hydraulic tank 4 is fixedly connected to a driven bevel gear 13, which meshes with the drive bevel gear 12. Its module is the same as that of the drive bevel gear 12, and the number of teeth is designed according to the transmission ratio. The driven bevel gear 13 is internally fixedly connected to a transmission rod 14. Both ends of the transmission rod 14 are mounted on bearing seats through bearings to ensure that the transmission rod 14 can rotate smoothly. The transmission rod 14 is externally fixedly connected to an eccentric wheel 15. The eccentric wheel 15 is circular in shape, but there is a certain eccentricity between the center of the circle and the center of rotation. The size of the eccentricity is designed according to the adjustment requirements of the device. The eccentric wheel 15 is externally rotatably connected to a drive plate 16, and the bottom of the drive plate 16 is fixedly connected to a follower plate 17.

[0035] The follower plate 17 is similar in shape to the drive plate 16, but slightly smaller in size. The bottom of the follower plate 17 is fixedly connected to the mounting plate 18. On the left and right sides of the mounting plate 18, a sliding groove structure is carefully designed. The width of the sliding groove is customized according to the size of the docking plug 27. Telescopic components are fixedly connected to the left and right sides of the mounting plate 18. The telescopic components include a mounting bracket 21. The function of the mounting bracket 21 is to install the connecting shaft 22. The mounting bracket 21 is fixedly connected to the left and right sides of the mounting plate 18. The connecting shaft 22 is rotatably connected inside the mounting bracket 21. The rotating plate 23 is rotatably connected to the outside of the connecting shaft 22. The telescopic rod 24 is fixedly connected to the outside of the rotating plate 23. A return spring 25 is sleeved on the outside of the telescopic rod 24. One end of the return spring 25 is fixedly connected to the outside of the rotating plate 23. The other end of the return spring 25 is fixedly connected to the top of the mounting plate 18. A positioning rod 26 is fixedly connected to the outside of the rotating plate 23. The function of the positioning rod 26 is to position and limit the rotation angle of the rotating plate 23.

[0036] Reference Figures 2 to 4 The mounting plate 18 has sliding connectors 27 on both the left and right sides. The connectors 27 are used to connect the heating ring 28 to the relevant circuit components on the mounting plate 18 and are silver-plated to reduce resistance and improve conductivity. The heating ring 28 is slidably connected to the outside of the hydraulic tank 4. One end of the connector is provided with a metal contact for circuit connection with the heating ring 28. The other end is designed with a slider that matches the groove of the mounting plate 18. The surface of the slider is polished and has extremely low roughness to ensure smooth sliding in the groove. The outside of the heating ring 28 is engaged with the outside of the connector 27. Limiting rods 29 are fixedly connected to the four corners of the heating ring 28. The limiting rods 29 are inserted into the mounting base and tightened with nuts to ensure that the limiting rods 29 are perpendicular to the base plate 1.

[0037] This provides a stable limiting effect for the heating ring 28, preventing it from shifting during operation. The limiting rod 29 is externally fixedly connected to the top of the base plate 1. The top of the mounting plate 18 is fixedly connected to the mounting power supply 19. The size of the mounting groove is precisely matched to the shape of the mounting power supply 19, ensuring that the mounting power supply 19 can be installed stably. The mounting power supply 19 is externally electrically connected to a power cord 20. One end of the power cord 20 is connected to the output end of the mounting power supply 19, and the other end is connected to the circuit interface of the electrical components such as the docking plug 27 to realize the transmission of electricity. The top of the hydraulic tank 4 is fixedly connected to an injection port 11, which is fixed to the top of the hydraulic tank 4 by welding or threaded connection. The four corners of the active rod 8 are all fixedly connected to stirring rods 30.

[0038] The function of the stirring rod 30 is to stir the hydraulic fluid in the hydraulic tank 4 when the drive rod 8 rotates, making the heating more uniform and accelerating the viscosity adjustment process of the hydraulic fluid. A scraper 31 is fixedly connected to the outside of the stirring rod 30. The scraper 31 can scrape off impurities or hydraulic fluid with uneven viscosity adhering to the inner wall of the hydraulic tank 4, promoting uniform mixing and heating of the hydraulic fluid. The outside of the scraper 31 fits in close contact with the inside of the hydraulic tank 4. A drive wheel 6 is fixedly connected to the outside of the drive rod 8. The groove design of the drive wheel 6 is adapted to the belt 7 to ensure that the belt 7 can fit tightly. The drive wheel 6 is mounted on the drive rod 8 to achieve efficient power transmission. When the drive rod 8 rotates under the drive of the motor 5, the drive wheel 6 rotates synchronously. The drive wheel 6 is fitted with a belt 7. The driven rod 9 is fixedly connected inside the hydraulic tank 4. The driven wheel 10 is fixedly connected to the bottom of the driven rod 9. The driven wheel 10 is connected to the drive wheel 6 through the belt 7. When the drive wheel 6 rotates under the drive of the drive rod 8, the belt 7 transmits power to the driven wheel 10, thereby driving the driven rod 9 to rotate, realizing auxiliary stirring of the hydraulic fluid in the hydraulic tank 4 or other related operations.

[0039] Working principle: By starting the motor 5, the driving wheel 6 drives the driven wheel 10 to rotate via the belt 7. This drives the driving wheel 6 and driven wheel 10 to rotate the driving rod 8 and driven rod 9, which in turn drives the stirring rod 30. The rotation of the driving rod 8 drives the driving bevel gear 12 to rotate. The driving bevel gear 12 then drives the transmission rod 14 to rotate via the driven bevel gear 13. This drives the transmission rod 14 to rotate the eccentric wheel 15. The eccentric wheel 15 then drives the drive plate 16 to rotate. The drive plate 16 then drives the mounting plate 18 to move via the follower plate 17. This causes the docking plug 27 to move the heating ring 28 outside the hydraulic tank 4 to heat the hydraulic oil inside the hydraulic tank 4.

[0040] When the position of the docking plug 27 is adjusted and inserted into the heating ring 28, pressing the rotating plate 23 causes it to squeeze the telescopic rod 24, which in turn causes the return spring 25 on the outside of the telescopic rod 24 to deform. This allows the rotating plate 23 to drive the positioning rod 26 to separate from the docking plug 27, thereby adjusting the docking plug 27 to lock into the heating ring 28 and energizing the heating ring 28. When locking the docking plug 27, releasing the rotating plate 23 causes the return spring 25 to rebound, which in turn locks the positioning rod 26 into the docking plug 27, thus fixing the docking plug 27 in place.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
