Description

Technical Field

[0002] The hydraulic station is a hydraulic source device or a hydraulic device including a control valve, which is composed of a hydraulic pump, a driving motor, an oil tank, etc. It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines where the driving device is separated from the hydraulic station. The hydraulic station is connected to the driving device (cylinder or motor) with an oil pipe, and the hydraulic system can achieve various specified actions; the hydraulic oil in the hydraulic station tank works under high pressure, and the temperature will gradually increase. It needs to be cooled by the cooling system to ensure the viscosity and stability of the hydraulic oil; when the hydraulic station supplies hydraulic oil, when the number of load-driven cylinders changes at the same time, the liquid level of the hydraulic oil in the storage tank will also rise and fall. When the liquid level is too low, it will increase the possibility of air inhalation into the oil pump, causing unstable operation of the hydraulic system.

The output drop pipe 701 sprays liquid to the center of the outer surface of the arc-surface heat-conducting plate 7 through the two-way shuttle pipe 702.

[0033] The other end of the output vertical pipe 701 is connected to a reverse oil pipe 703, one end of which extends upward to the outside of the oil storage tank 1, a flange 704 is fixedly provided at the end of the reverse oil pipe 703, and a one-way oil valve 705 is provided in the reverse oil pipe 703. The one-way oil valve 705 allows the oil to flow in the reverse oil pipe 703 in one direction toward the output vertical pipe 701.

[0034] The external connection of the reverse oil pipe 703 is provided with an auxiliary branch pipe 706, and the end of the auxiliary branch pipe 706 is connected with a driving oil pipe 707. The driving oil pipe 707 is located below the hydraulic oil level in the oil storage tank 1. An oil suction end hole 708 is opened at the end of the driving oil pipe 707, and a one-way blocking disk 709 is provided to seal the inner side of the oil suction end hole 708.

[0035] A supporting spring piece 710 is fixedly provided on the surface of the one-way blocking disk 709, and the supporting spring piece 710 is fixedly connected to the driving oil pipe 707. A limiting inner ring 711 is fixedly provided on the inner wall surface of the driving oil pipe 707. A movable piston 712 is provided on the side of the limiting inner ring 711 away from the oil suction end hole 708, and the movable piston 712 is in sliding sealing contact with the inner wall surface of the driving oil pipe 707.

[0036] A return spring 713 is arranged between the limiting inner ring 711 and the moving piston 712, and a cam plate 714 is arranged on the side of the moving piston 712 away from the return spring 713. When the cam plate 714 rotates, the moving piston 712 can be squeezed and driven, so that the moving piston 712 moves axially toward the return spring 713. A cam shaft 715 is fixedly arranged in the cam plate 714. The cam shaft 715 is sealed and inserted through the top wall of the oil storage tank 1 and extends to the outside of the oil storage tank 1. A cam driving module 716 is fixedly arranged on the surface of the oil storage tank 1. The cam driving module 716 is used to drive the cam shaft 715 to rotate. The cam driving module 716 is composed of a motor and a reduction gear set.

[0037] An oil observation window 101 is embedded in the surface of the oil storage tank 1, and an oil pump motor 102 is fixedly installed on the oil storage tank 1. The oil pump motor 102 is used to drive the hydraulic oil pump 2 to operate. A minimum liquid level sensor 103 for monitoring the liquid level of the hydraulic oil is arranged on the inner wall surface of the oil storage tank 1.

[0038] A cooling fan 901 is disposed outside the cooling fin 9 , and a flow-through inner cavity 902 is provided in the cooling fin 9 . The flow-dividing frame plates 8 located on both sides of the cooling fin 9 are connected to each other through the flow-through inner cavity 902 .

[0039] When the hydraulic station cooling system of the present invention is in use, the axial flow driver 10 drives and controls the cooling medium in the support tube 4, the reflux support tube 5, the arcuate heat-conducting plate 7 and the heat dissipation fins 9 to circulate. The cooling medium filled in the above structure can be air, water or oil, etc. The heat of the hydraulic oil in the oil storage tank 1 is transferred to the cooling medium through the arcuate heat-conducting plate 7, and the cooling medium moves to the heat dissipation fins 9 and contacts with the air to release heat.

[0040] When the hydraulic oil level in the oil tank 1 is lower than the position of the minimum level sensor 103, Figure 4 As shown in the figure, the screw shaft 408 is controlled to rotate by the screw motor group 409, so that the T-shaped moving frame 405 is driven, and the T-shaped moving frame 405 pushes the control piston 403 to move the axis through the piston shaft 404, and pushes the cooling medium in the cache tube cavity 401 into the control bracket tube 4; at this time, the pressure in the control bracket tube 4, the reflux bracket tube 5, the arcuate heat conducting plate 7 and the heat dissipation fins 9 and other structures increases. When the pressure in the connecting ring frame 6 and the arcuate heat conducting plate 7 is greater than the thrust required for the deformation of the arcuate heat conducting plate 7, the arcuate heat conducting plate 7 will bulge outward in a spherical shape, that is, the arcuate heat conducting plate 7 is from Figure 6 The concave state shown in the figure is switched to a convex state, thereby increasing the volume occupied by the arc-surface heat-conducting plate 7, so that the liquid level in the oil storage tank 1 rises.

[0041] The reverse oil pipe 703 is connected to the external hydraulic return oil pipeline through the flange 704, and the returned hydraulic oil flows into the output vertical pipe 701 through the one-way oil valve 705, and is sprayed to the center position of the outer surface of the arc-surface heat-conducting plate 7 through the two-way shuttle tube 702; so that the high-temperature hydraulic oil first directly contacts the arc-surface heat-conducting plate 7 to improve the heat dissipation efficiency, and at the same time, the concave or convex spherical surface of the arc-surface heat-conducting plate 7 can be used to radially diffuse the returned hydraulic oil sprayed from the two-way shuttle tube 702 to the surroundings, so that the hydraulic oil in the oil storage tank 1 can be fully mixed; at the same time, the injection pressure of the two-way shuttle tube 702 can flush the surface of the arc-surface heat-conducting plate 7.

[0042] The cam drive module 716 drives the cam shaft 715 to rotate, thereby driving the cam plate 714 to rotate. When the cam plate 714 rotates, it can squeeze and drive the movable piston 712, so that the movable piston 712 moves axially toward the return spring 713. Since the cam plate 714 is a cam, as the protrusion passes through the movable piston 712 as it rotates, it loses the squeezing push, and thus cooperates with the return spring 713 to make the movable piston 712 in an axial reciprocating motion.

[0043] When the movable piston 712 moves away from the oil suction end hole 708, a part of the external oil will push open the one-way blocking plate 709 and enter the driving oil pipe 707, and the other part of the oil in the reverse oil pipe 703 will be sucked into the driving oil pipe 707 at the same time. A one-way valve can also be set in the auxiliary branch pipe 706 to prevent the oil in the reverse oil pipe 703 from entering the driving oil pipe 707; when the movable piston 712 moves toward the oil suction end hole 708, the oil in the driving oil pipe 707 is squeezed into the reverse oil pipe 703 through the auxiliary branch pipe 706, so that the injection pressure of the two-way shuttle tube 702 is increased and has a fluctuating pulse, thereby improving the cleaning effect of the arc surface heat conduction plate 7, and at the same time increasing the sputtering range of the hydraulic oil sprayed from the two-way shuttle tube 702 to diffuse radially around, thereby improving the mixing degree.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
