It supplies oil according to the flow direction, pressure and flow required by the driving device. It is suitable for various machines in which the driving device is separated from the hydraulic station. By connecting the hydraulic station and the driving device with an oil pipe, the hydraulic system can achieve various specified actions.

[0003] Hydraulic oil itself has good lubricity and wear resistance. When the hydraulic oil temperature environment is not lower than 35℃ and not higher than 50℃, hydraulic equipment can maintain the best working condition. However, when the equipment is running for a long time, the hydraulic station often has too high oil temperature, resulting in a high failure rate of the hydraulic system, which seriously affects the safe and stable operation of the lifting system, such as: causing the viscosity of the hydraulic oil, volumetric efficiency and hydraulic system efficiency to decrease; the system components overheat and expand, and the wear is aggravated, causing the precision matching surfaces of pumps, valves, motors, etc. to fail or be scrapped due to premature wear; accelerating the aging and deterioration of rubber seals, shortening their life, and even losing their sealing performance, causing serious leakage in the hydraulic system.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0023] like Figure 1-3As shown, in the embodiment, a brake hydraulic station heat dissipation device is provided, which is arranged on the hydraulic station body 1. The hydraulic station body 1 is provided with a heat dissipation mechanism 2, and the heat dissipation mechanism 2 includes a shell 21, a circulation pump 22, a heat dissipation main pipe 23, a heat dissipation branch pipe 24, a temperature sensor 25, a heat dissipation fan 26 and a controller 27. The shell 21 is arranged on one side of the hydraulic station body 1, and a heat dissipation cavity 211 is arranged in the shell 21. The heat dissipation main pipes 23 are vertically arranged at both ends of the heat dissipation cavity 211, and two or more heat dissipation main pipes 23 are connected between the two heat dissipation main pipes 23. The heat branch pipe 24 is connected, and the free end of the heat dissipation main pipe 23 is connected to the hydraulic station body 1. A circulating pump 22 and a temperature sensor 25 are connected to one of the heat dissipation main pipes 23. A ventilation hole 212 communicating with the heat dissipation cavity 211 is provided on one side of the housing 21. A heat dissipation fan 26 is provided in the ventilation hole 212. The controller 27 is fixed on the outer wall of the housing 21. An auxiliary cooling mechanism 3 is also provided in the heat dissipation cavity 211, and the circulating pump 22, the temperature sensor 25, the heat dissipation fan 26 and the auxiliary cooling mechanism 3 are all electrically connected to the controller 27. In this embodiment, since the hydraulic oil will heat up after working for a long time, causing the equipment to be unable to maintain the best working state, the heat dissipation mechanism 2 is provided to dissipate the heat for the hydraulic oil in the hydraulic station body 1 to ensure that the oil temperature is in a suitable range. Among them, the shell 21 is a rectangular shell, and a gap is reserved between the shell 21 and the outer wall of the hydraulic station body 1 for air to circulate between the heat dissipation cavity 211 and the external environment; more than two heat dissipation branches 24 are provided, and the more than two heat dissipation branches 24 are horizontally arranged in the heat dissipation cavity 211 from top to bottom; the circulating pump 22 provided can pump the hydraulic oil in the oil tank inside the hydraulic station body 1 to the heat dissipation main pipe 23 and the heat dissipation branch pipe 24 for heat dissipation, thereby increasing the heat dissipation area and improving the heat dissipation efficiency; the temperature sensor 25 is provided at one end of the heat dissipation main pipe 23 close to the hydraulic station body 1, which can monitor the temperature of the hydraulic oil in real time and transmit the detection result to the controller 27 for analysis and processing. When the temperature is high, the controller 27 will control the speed of the heat dissipation fan 26 to increase, thereby accelerating the gas flow rate, so that the heat exchange effect between the heat dissipation main pipe 23 and the heat dissipation branch pipe 24 and the cold air is improved. On the contrary, when the temperature is low, the speed of the heat dissipation fan 26 will be controlled to slow down or even stop rotating to ensure that the hydraulic oil is always at the optimal working temperature of 35°C to 50°C. The auxiliary cooling mechanism 3 is used to assist the heat dissipation mechanism 2 in heat dissipation. The controller 27 has an optimal operating temperature range of the hydraulic oil preset, and the controller 27 can control the circulation pump 22, the temperature sensor 25, the heat dissipation fan 26 and the auxiliary cooling mechanism 3 to work together.

[0024] Specifically, a fixing member 28 is provided on the housing 21, and the fixing member 28 includes a fixing plate 281, a cushion block 282 and a fastening bolt 283. The fixing plates 281 are fixed on both sides of the housing 21, and a cushion block 282 is provided on one side of the fixing plate 281. The fastening bolt 283 passes through the fixing plate 281 and the cushion block 282 in sequence and is threadedly connected to the hydraulic station body 1. In this embodiment, the fixing member 28 is provided so that the housing 21 and the hydraulic station body 1 can be detachably connected, so that the heat dissipation mechanism 2 can be removed for cleaning, replacement, maintenance, etc., wherein the fixing plate 281 is a flat plate and is fixed on the housing 21 by welding; the cushion block 282 is provided between the fixing plate 281 and the outer wall of the hydraulic station body 1, so that a certain gap is reserved between the housing 21 and the hydraulic station body 1, and the airflow generated by the rotation of the heat dissipation fan 26 will be discharged from the housing 21 through the gap after heat exchange with the heat dissipation main pipe 23 and the heat dissipation branch pipe 24, and the airflow will also cool the shell of the hydraulic station body 1 while being discharged through the gap.

[0025] Specifically, the auxiliary cooling mechanism 3 includes a heat-conducting ring 31 and a heat expansion ring 32. The heat-conducting ring 31 is sleeved on the heat-dissipating branch pipe 24, and the heat expansion ring 32 is fixed on the outer wall of the heat-conducting ring 31. In this embodiment, the heat-dissipating branch pipe 24 is preferably a flexible pipe. The heat-conducting ring 31 is made of a metal material with high thermal conductivity, such as copper, which can improve the heat exchange efficiency between the heat-dissipating branch pipe 24 and the cold air. The set heat expansion ring 32 can expand when heated, thereby increasing the gap between two adjacent heat-dissipating branch pipes 24. At this time, the ventilation volume in the gap increases, which helps to improve the heat exchange efficiency. When the heat expansion ring 32 is not heated or the temperature of the surface of the heat-conducting ring 31 is low, it will shrink, so that the gap between the two adjacent heat-dissipating branch pipes 24 is reduced. At this time, the ventilation volume in the gap is reduced, and the heat exchange effect between the heat-conducting ring 31 and the cold air becomes worse, so that the temperature of the hydraulic oil can be prevented from being too low, thereby playing the purpose of assisting in regulating the temperature of the hydraulic oil.

[0026] Specifically, a water tank 33 is further provided on the top wall of the heat dissipation cavity 211, a water inlet 34 is provided on the top of the water tank 33, a spray pipe 36 is transversely provided below the water tank 33, and one end of the spray pipe 36 is connected to a pump body 35 at the bottom of the water tank 33, and nozzles 37 are evenly provided on the spray pipe 36. In this embodiment, cooling water is filled in the water tank 33, and after the cooling water is used up, the staff can add water to the water tank 33 through the water inlet 34 on the top. The pump body 35 is provided to pump the cooling water in the water tank 33 into the spray pipe 36, and then the water mist is sprayed by the nozzle 37 and falls on the surface of the heat-conducting ring 31. At this time, the airflow blows the water droplets to make them evaporate and absorb heat, so as to achieve the purpose of auxiliary cooling of the hydraulic oil.

[0027] Specifically, a dust filter 4 is further provided on one side of the cooling fan 26, and the dust filter 4 is fixed on the housing 21. In this embodiment, the dust filter 4 can filter out dust in the air and prevent dust from adhering to the surface of components in the housing 21.

[0028] Specifically, the controller 27 is provided with a touch screen 271. In this embodiment, the touch screen 271 can display the speed of the cooling fan 26, the temperature of the hydraulic oil and other information in real time, so that the staff can understand the working status of the equipment and adjust the equipment parameters adaptively.

[0029] Working principle: When in use, the temperature sensor 25 monitors the temperature of the hydraulic oil in real time. When the temperature is high, the circulating pump 22 is controlled to start. The circulating pump 22 controls the hydraulic oil in the hydraulic station body 1 to pass through the heat dissipation main pipe 23 on the left, the heat dissipation branch pipe 24, and the heat dissipation main pipe 23 on the right in turn and return to the oil tank in the hydraulic station body 1 to achieve circulating cooling. Then the controller 27 controls the cooling fan 26 to start. The rotation of the cooling fan 26 will generate a cold air flow and exchange heat with the heat conduction ring 31 and the heat dissipation main pipe 23, thereby cooling the hydraulic oil, and the heat expansion ring 32 will expand when heated, thereby causing the two adjacent heat dissipation branch pipes 24 to move away from each other, so that the gap becomes larger. At this time, the ventilation volume in the gap becomes larger, and the heat exchange effect is better. At the same time, the pump body 35 is started, and the pump body 35 sprays the water in the water tank 33 from the nozzle 37 to the surface of the heat conduction ring 31. At this time, the air flow causes the water mist to evaporate and absorb a large amount of heat, which plays a role in assisting the cooling of the hydraulic oil. When the temperature drops, the controller 27 controls the speed of the cooling fan 26 to slow down, thereby slowing down the air flow speed. At the same time, the thermal expansion ring 32 will shrink so that the adjacent cooling branch pipes 24 are close to each other, thereby reducing the air volume passing through the gaps between the adjacent cooling branch pipes 24, reducing the cooling efficiency, and preventing the hydraulic oil temperature from being too low.
