Description

Technical Field

[0001] This invention relates to the field of hydraulic system cooling technology, specifically to a hydraulic system having multiple cooling structures. Background Technology

[0002] A hydraulic system generally consists of five parts: power components, actuators, control components, auxiliary components, and hydraulic oil. In high-temperature environments, if the hydraulic oil is not cooled in time, it will deteriorate, thus affecting the operation of the hydraulic system.

[0003] A search revealed a cooling device for a hydraulic system, disclosed in publication number CN205639178U. This device uses a pump-driven chiller to pre-cool the cooling water, ensuring a large temperature difference between the hydraulic oil and the cooling water and improving the cooling effect. However, it has the following drawbacks: the device has only one mechanism for cooling the hydraulic oil, which can easily lead to the hydraulic oil being discharged and reused before it is fully cooled, resulting in high hydraulic oil temperature and thus deterioration of the hydraulic oil.

A second pump-driven chiller is fixedly connected to the top of the first pump-driven chiller. The upper surface of the base plate frame is provided with a power mechanism for turbulenting of the hydraulic oil inside the cooling water tank and driving the rotating cylinder and the rotating disk to rotate.

[0009] Furthermore, the third cooling mechanism includes a cooling water pipe, one end of which is fixed and connected to the first pumped chiller, and the other end of which passes through the cooling water tank and is fixed and connected to the first pumped chiller.

[0010] Based on the aforementioned scheme, the second cooling mechanism includes an outlet pipe and a return pipe. One end of the outlet pipe and the return pipe are fixed and connected to the second pumped chiller. The other end of the outlet pipe and the return pipe are fixed to the upper fixed plate and the lower fixed plate, respectively, and connected to the rotating cylinder.

[0011] As a further embodiment of the present invention, the third cooling mechanism includes an electric fan, which is fixed to the rotating disk.

[0012] Furthermore, the power mechanism includes a motor, which is fixed to the base frame. One end of the motor's output shaft is fixedly connected to a crankshaft, and one end of the crankshaft passes through a cooling water tank and is keyed to a gear. A fixed ring is rotatably connected inside the cooling water tank, and a gear ring is fixedly connected inside the fixed ring, meshing with the gear. Multiple agitator plates are fixedly connected to one side of the fixed ring. A rotating plate is rotatably connected inside the crankshaft, and a sliding plate is rotatably connected to the top of the rotating plate. A sliding groove is provided on one side of the sliding plate, and a slider is slidably connected inside the sliding groove. A fixed rod is fixedly connected to one side of the slider and is fixed to the cooling water tank. A guide rod is fixedly connected to one side of the sliding plate. A guide groove is provided on the outer side of the rotating cylinder, and the guide rod is slidably connected to the guide groove. An L-shaped frame is fixedly connected to the outer side of the rotating cylinder, and a pawl is rotatably connected to the top of the L-shaped frame.

[0013] Based on the aforementioned scheme, multiple baffles are fixedly connected inside the rotating cylinder, and two baffles are fixedly connected to the upper surface of each of the multiple baffles.

[0014] As a further embodiment of the present invention, a fixing frame is fixedly connected to the outer circumferential wall of the cooling water tank, and the fixing frame is fixed to the upper fixing plate.

[0015] Furthermore, the outer circumferential wall of the cooling water tank is provided with an oil outlet, and an oil outlet pipe is fixedly connected inside the oil outlet.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a hydraulic system with multiple cooling structures, which has the following advantages:

[0018] 1. Through the coordinated use of the first, second, and third cooling mechanisms, the hydraulic oil in the oil inlet pipe is cooled by the first, second, and third cooling mechanisms, allowing the hydraulic oil to be cooled multiple times, thus ensuring that the hydraulic oil is completely cooled and preventing the hydraulic oil from deteriorating due to excessive temperature.

[0019] 2. Through the setting of the drive mechanism, the motor drives the crankshaft to rotate. The crankshaft drives the fixed ring to rotate through the meshing of gears and gear rings. During the rotation of the fixed ring, the agitator plate will rotate, causing the agitator plate to agitate the hydraulic oil in the cooling water tank. This turbulence of the hydraulic oil in the cooling water tank allows the hydraulic oil to make more comprehensive contact with the cooling water pipes, further improving the cooling effect of the third cooling mechanism on the hydraulic oil.

[0020] 3. Through the combined use of baffles and baffles, the baffles and baffles can turbulent the cooling water entering the rotating cylinder, so that the cooling water in the rotating cylinder can make more comprehensive contact with the oil inlet pipe, thereby further improving the cooling effect of the second cooling mechanism on the hydraulic oil.

[0021] 4. Through the coordinated use of pawls and ratchet teeth, the crankshaft rotation drives the rotating plate to perform circular motion. Simultaneously, with the cooperation of the slider and the slide groove, the rotating plate drives the slide plate to perform up-and-down reciprocating motion. The slide plate drives the guide rod to move. When the slide plate moves upward, the guide rod, in cooperation with the guide groove, causes the rotating cylinder to rotate. The rotating cylinder drives the L-shaped frame to move. The L-shaped frame, through the cooperation of pawls and ratchet teeth, pushes the rotating disk to rotate. The rotating disk drives the electric fan to rotate. When the slide plate moves downward, it causes the rotating cylinder to reverse, while the rotating disk does not rotate. This allows the electric fan to blow air from all directions onto the oil inlet pipe, further improving the cooling effect of the first cooling mechanism on the hydraulic oil.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-6A hydraulic system with multiple cooling structures includes a base plate frame 1. Two feet 9 are bolted to the upper surface of the base plate frame 1. A cooling water tank 8 is bolted to the top of each foot 9. The cooling water tank 8 contains a third cooling mechanism for cooling hydraulic oil. A lower fixed plate 23 is welded to the outer circumference of the cooling water tank 8. A rotating cylinder 24 is rotatably connected to the upper surface of the lower fixed plate 23. A second cooling mechanism for cooling hydraulic oil is located inside the rotating cylinder 24. An upper fixed plate 11 is rotatably connected to the top of the rotating cylinder 24. A rotating frame 29 is rotatably connected to the upper surface of the upper fixed plate 11. A rotating plate 27 is bolted to the top of the rotating frame 29. A first cooling mechanism for cooling hydraulic oil is located on the upper surface of the rotating plate 27. An oil inlet pipe 5 is welded to the outside of the cooling water tank 8 and is connected to the cooling water tank 8. Hydraulic oil is added to the inlet pipe 5, flows through the inlet pipe 5, and enters the cooling water tank 8. One end of the inlet pipe 5 passes through the lower fixed plate 23, the rotating cylinder 24, the upper fixed plate 11, the rotating frame 29, and the rotating disk 27. Multiple pads 4 are fixed to the upper surface of the base plate 1 by bolts. The first pump chiller 2 is fixed to the upper surface of the multiple pads 4 by bolts. The second pump chiller 3 is fixed to the top of the first pump chiller 2 by bolts. The first cooling mechanism, the second cooling mechanism, and the third cooling mechanism will all cool the hydraulic oil in the inlet pipe 5, so that the hydraulic oil can be cooled multiple times, thereby allowing the hydraulic oil to be completely cooled and preventing the hydraulic oil from deteriorating due to excessive temperature. The upper surface of the base plate 1 is provided with a power mechanism that turbulents the hydraulic oil inside the cooling water tank 8 and drives the rotating cylinder 24 and the rotating disk 27 to rotate.

[0031] In particular, the third cooling mechanism of this invention includes a cooling water pipe 7, one end of which is fixed and connected to the first pumped chiller 2, and the other end of which passes through the cooling water tank 8 and is fixed and connected to the first pumped chiller 2. The second cooling mechanism includes an outlet pipe 36 and a return pipe 25, one end of which is fixed and connected to the second pumped chiller 3, and the other ends of which are fixed to the upper fixed plate 11 and the lower fixed plate 23 respectively and connected to the rotating cylinder 24. The third cooling mechanism includes an electric fan 26, which is fixed to the rotating plate 27. When the first pumped chiller 2, the second pumped chiller 3, and the electric fan 26 are started, the electric fan 26 blows air onto the oil inlet pipe 5. The hydraulic oil inside is cooled. Cooling water from the second pump-driven chiller 3 enters the rotating drum 24 through the outlet pipe 36, allowing the cooling water to contact the oil inlet pipe 5. This heat exchange between the cooling water and the hydraulic oil in the oil inlet pipe 5 provides secondary cooling. The cooling water then returns to the second pump-driven chiller 3 through the return pipe 25 for further cooling. Simultaneously, the cooling water from the first pump-driven chiller 2 drives the flow in the cooling water pipe 7, bringing the cooling water in the cooling water pipe 7 into contact with the hydraulic oil in the cooling water tank 8. This heat exchange between the cooling water and the hydraulic oil in the cooling water tank 8 provides tertiary cooling. Finally, the cooling water returns to the first pump-driven chiller 2 for further cooling, thus providing multiple cooling cycles for the hydraulic oil. The system ensures complete cooling of the hydraulic oil, preventing overheating and deterioration. The power mechanism includes a motor, fixed to the base frame 1. One end of the motor output shaft is bolted to a crankshaft 17. One end of the crankshaft 17 passes through a cooling water tank 8 and is keyed to a gear 12. A fixed ring 13 is rotatably connected inside the cooling water tank 8. A gear ring 16 is bolted to the fixed ring 13, meshing with the gear 12. Multiple agitator plates 14 are welded to one side of the fixed ring 13. A rotating plate 18 is rotatably connected inside the crankshaft 17. A sliding plate 19 is rotatably connected to the top of the rotating plate 18. A groove 20 is formed on one side of the sliding plate 19, within which a slider 21 is slidably connected. A fixed rod 15 is bolted to one side of the slider 21, and the fixed rod 15 is connected to the cooling water tank 8. The water tank 8 is fixed in place. A guide rod 22 is welded to one side of the slide plate 19. A guide groove 31 is provided on the outer side of the rotating cylinder 24, and the guide rod 22 is slidably connected to the guide groove 31. An L-shaped frame 30 is welded to the outer side of the rotating cylinder 24. A pawl 32 is rotatably connected to the top of the L-shaped frame 30. A torsion spring 33 is welded to the upper surface of the pawl 32, and the torsion spring 33 is fixed to the L-shaped frame 30. Multiple ratchet teeth 28 are provided on the outer side of the rotating disk 27, and the pawl 32 meshes with the ratchet teeth 28. At the same time, the motor is started, which drives the crankshaft 17 to rotate. The crankshaft 17 drives the gear 12 to rotate. The gear 12, through meshing with the gear ring 16, drives the fixed ring 13 to rotate. The fixed ring 13 drives the agitator 14 to rotate, so that the agitator 14 agitates the hydraulic oil in the cooling water tank 8.This allows the hydraulic oil in the cooling water tank 8 to make more comprehensive contact with the cooling water pipes 7, further improving the cooling effect of the third cooling mechanism on the hydraulic oil. As the crankshaft 17 rotates, it drives the rotating plate 18 to rotate in a circular motion. The rotating plate 18 rotates with the sliding plate 19. Since the slider 21 is fixed by the fixing rod 15, the cooperation between the slider 21 and the slide groove 20 causes the rotating plate 18 to move the sliding plate 19 up and down, and the slider 21 to move within the slide groove 20. When the sliding plate 19 moves upward, it drives the guide rod 22 upward. The guide rod 22 moves along the guide groove 31, thereby pushing the rotating cylinder 24 to rotate. The rotating cylinder 24 drives the L-shaped frame 30 to rotate. The L-shaped frame 30, through the cooperation of the pawl 32 and the ratchet 28, pushes the rotating disk 27 to rotate. The rotating disk 27 drives the electric fan 26 to rotate. When the sliding plate 19 moves downward, the rotating cylinder 24 rotates in the opposite direction, at which point the rotating cylinder 24 drives the L-shaped frame... The rotating cylinder 24 rotates in the opposite direction, at which time the ratchet 28 pushes the pawl 32 to rotate and the torsion spring 33 to generate torque. The pawl 32 then engages with the next ratchet 28 through the torque of the torsion spring 33, until the rotating cylinder 24 rotates in the forward direction. This cycle repeats, allowing the electric fan 26 to blow air onto the oil inlet pipe 5 comprehensively, further improving the cooling effect of the first cooling mechanism on the hydraulic oil. Multiple baffles 34 are welded inside the rotating cylinder 24. Two baffles 35 are bolted to the upper surface of each baffle 34. When cooling water enters the rotating cylinder 24, the baffles 35 inside the rotating cylinder 24 turbulent the cooling water, allowing the cooling water inside the rotating cylinder 24 to make more comprehensive contact with the oil inlet pipe 5, thereby further improving the cooling effect of the second cooling mechanism on the hydraulic oil. A fixing bracket 10 is welded to the outer circumference of the cooling water tank 8, and the fixing bracket 10 is fixed to the upper fixing plate 11. An oil outlet is opened on the outer circumference of the cooling water tank 8, and an oil outlet pipe 6 is welded inside the oil outlet.

[0032] Working principle of this embodiment: During use, hydraulic oil is added to the inlet pipe 5. The hydraulic oil flows in the inlet pipe 5 and enters the cooling water tank 8. At the same time, the first pump-driven chiller 2, the second pump-driven chiller 3, and the electric fan 26 are started. The electric fan 26 blows air onto the inlet pipe 5 to cool the hydraulic oil inside. The cooling water in the second pump-driven chiller 3 enters the rotating drum 24 through the outlet pipe 36, so that the cooling water comes into contact with the inlet pipe 5. This allows for heat exchange between the cooling water and the hydraulic oil in the inlet pipe 5, providing secondary cooling for the hydraulic oil. Then, the cooling water returns to the second pump-driven chiller 3 through the return pipe 25 for further cooling. Meanwhile, the cooling water in the first pump-driven chiller 2 drives the flow in the cooling water pipe 7. The motor activates the hydraulic system, bringing the cooling water in the cooling water pipe 7 into contact with the hydraulic oil in the cooling water tank 8. This allows for heat exchange between the cooling water and the hydraulic oil in the cooling water tank 8, resulting in three cooling cycles for the hydraulic oil. Finally, the cooling water returns to the first pump-driven chiller 2 for further cooling. This multiple cooling process ensures the hydraulic oil is completely cooled, preventing it from overheating and deteriorating. Simultaneously, the motor starts, driving the crankshaft 17 to rotate. The crankshaft 17 then drives the gear 12, which in turn rotates the fixed ring 13 through meshing with the gear ring 16. The fixed ring 13 then drives the agitator 14 to rotate, causing the agitator 14 to agitate the hydraulic oil in the cooling water tank 8, ensuring more comprehensive cooling of the hydraulic oil. The cooling water pipe 7 makes contact, further improving the cooling effect of the third cooling mechanism on the hydraulic oil. While the crankshaft 17 rotates, it drives the rotating plate 18 to rotate. The rotating plate 18 rotates with the sliding plate 19. Since the slider 21 is fixed by the fixing rod 15, the cooperation between the slider 21 and the slide groove 20 causes the rotating plate 18 to move the sliding plate 19 up and down, and the slider 21 to move within the slide groove 20. When the sliding plate 19 moves upward, it drives the guide rod 22 upward. The guide rod 22 moves along the guide groove 31, thereby pushing the rotating cylinder 24 to rotate. The rotating cylinder 24 drives the L-shaped frame 30 to rotate. The L-shaped frame 30, through the cooperation of the pawl 32 and the ratchet 28, pushes the rotating disk 27 to rotate. The disc 27 drives the electric fan 26 to rotate. When the slide plate 19 moves downward, it causes the rotating cylinder 24 to rotate in the opposite direction. This rotating cylinder 24 then drives the L-shaped frame 30 to rotate in the opposite direction. Simultaneously, the ratchet 28 pushes the pawl 32 to rotate, causing the torsion spring 33 to generate torque. The pawl 32 then engages with the next ratchet 28 through the torque of the torsion spring 33, until the rotating cylinder 24 rotates forward. This cycle repeats, allowing the electric fan 26 to provide comprehensive airflow to the oil inlet pipe 5, further improving the cooling effect of the first cooling mechanism on the hydraulic oil. When cooling water enters the rotating cylinder 24, the baffle 35 inside the rotating cylinder 24 turbulents the cooling water, ensuring more comprehensive contact between the cooling water in the rotating cylinder 24 and the oil inlet pipe 5.This further improves the cooling effect of the second cooling mechanism on the hydraulic oil.
