Description

Technical Field

[0001] This invention relates to the field of hydraulic oil pipe cooling technology, and more particularly to a hydraulic oil pipe cooling device to prevent overheating. Background Technology

[0002] Hydraulic oil, as a crucial force transmission medium in hydraulic systems, directly affects the system's operating efficiency and stability due to its temperature. Excessive hydraulic oil temperature can trigger a series of problems. First, high temperatures reduce the viscosity of the hydraulic oil, which not only increases internal leakage but also reduces the accuracy and efficiency of system movements. Therefore, it is necessary to cool the oil within the hydraulic lines.

[0003] Chinese Patent CN116241529B discloses a spiral internal circulation rapid cooling hydraulic oil pipe, relating to the field of hydraulic oil pipe cooling. It includes: a hydraulic oil pipe body; two hydraulic oil pipe bodies connected by a connecting hose; and a cooling mechanism on the outside of each hydraulic oil pipe body. While this patent can cool the oil, it only does so through external cooling pipes. If the oil flow rate is too fast, the oil at the center of the hydraulic oil pipe is subjected to compression and shearing from the surrounding oil, resulting in relatively low heat transfer efficiency and preventing timely dissipation, thus affecting the cooling effect.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, a hydraulic oil pipe cooling device that can cool the oil from both the inside and outside simultaneously and improve the cooling effect of the oil is proposed to prevent overheating. Summary of the Invention

[0005] To overcome the shortcomings of the aforementioned patents, which only rely on external cooling pipes to cool the hydraulic fluid, and where the fluid flow rate is too fast, the fluid located at the center of the hydraulic pipe is subjected to compression and shearing from the surrounding fluid, resulting in relatively low heat transfer efficiency and inability to dissipate heat in time, thus affecting the cooling effect, this invention provides a hydraulic pipe cooling device that can cool the fluid simultaneously from the inside and outside, thereby improving the cooling effect and preventing overheating.

[0006] This invention is achieved through the following technical solution:

[0007] A hydraulic oil cooling device for preventing overheating includes a cylinder and an inlet pipe fixedly connected to the cylinder. An outlet pipe is fixedly connected to the cylinder. A circular shell is fixedly connected to the end of the inlet pipe, and an electric dispersion wheel is installed on the circular shell. The device also includes evenly spaced branch pipes fixedly connected to the inner side of the cylinder. One end of the branch pipe is circumferentially connected to the circular shell, and the other end of the branch pipe is connected to the end of the outlet pipe. A cooling frame is fixedly fitted between the branch pipes. Cooling pipes are evenly spaced and fixedly connected to the cooling frame and the branch pipes. The number of cooling pipes gradually increases from left to right. Branch pipes are symmetrically connected to the cooling pipes. A circulation assembly is provided between the cylinder and the cooling pipes. The circulation assembly is used to discharge coolant into the cooling pipes. Part of the coolant in the cooling pipes is discharged into the cooling frame through the branch pipes and contacts the outer wall of the branch pipes, so that the coolant cools the oil from the inside and outside simultaneously through the cooling pipes and the cooling frame. An air blowing assembly is provided on the cylinder for air cooling of the cooling pipes and the cooling frame.

[0008] Further explanation includes guide plates fixed to both sides of the flow divider pipe at even intervals, with the guide plates on both sides arranged alternately to guide and block the oil.

[0009] Further explanation: The circulation assembly includes a liquid guide shell connected between the top and bottom ends of the cooling pipes, and circulation pumps are installed laterally and evenly on the inner side of the cylinder. The outlet end of the circulation pump is connected to one of the liquid guide shells, and the inlet end of the circulation pump is connected to the other liquid guide shell.

[0010] Further explanation: The air blowing assembly includes filter screens fixedly inserted around the circumference of the cylinder at uniform intervals. An annular nozzle is fixedly connected to the inner side of the cylinder along the circumference to blow air out to cool the cooling pipe and cooling frame. An n-shaped frame is fixedly connected to the cylinder. Control valves are installed at both discharge ends of the n-shaped frame. A three-way pipe is connected between the ends of the control valves. The air outlet end of the three-way pipe passes through the cylinder and is connected to the annular nozzle. A switch valve I is rotatably connected to the n-shaped frame. The channel of switch valve I is L-shaped. A drive motor is installed on the outer side of the n-shaped frame. The output shaft end of the drive motor is fixedly connected to the end of switch valve I. An air supply pump is installed on the cylinder. The air outlet end of the air supply pump is connected to the n-shaped frame. The air supply pump is connected to switch valve I. A filter assembly is provided on the n-shaped frame to filter impurities in the air.

[0011] Further explanation: The filter assembly includes a discharge pipe symmetrically connected to the n-shaped frame for discharging impurities. A switching valve II is rotatably connected to the discharge pipe. The end of the switching valve II is connected to the switching valve I via a synchronous belt assembly. The channel of the switching valve II is L-shaped. Baffles are symmetrically fixed to both sides of the n-shaped frame. An electric filter cartridge is installed between each side of the baffles for filtering impurities in the air. A brush plate that contacts the inner wall of the electric filter cartridge is symmetrically fixed to one of the baffles for removing impurities adhering to the inner wall of the electric filter cartridge. A bidirectional air pump is installed between the two sides of the n-shaped frame.

[0012] Further explanation: The hydraulic oil cooling device for preventing overheating also includes a diversion assembly. The diversion assembly includes a housing installed between the diversion pipes. Electrically controlled drain pipes are connected to the housing at even intervals along the circumference, with the tail end of the electrically controlled drain pipe connected to the diversion pipe. Electrically controlled suction pipes are also connected to the housing at even intervals along the circumference, with the tail end of the electrically controlled suction pipe connected to the diversion pipe, for drawing a portion of the oil from the diversion pipe into the housing. A temperature sensor is installed on the diversion pipe, and the temperature sensor is electrically connected to the electrically controlled drain pipe and the electrically controlled suction pipe through a control module. A conveying assembly is provided on the housing for moving the oil to the left for conveying.

[0013] Further explanation: the conveying assembly includes a spiral conveying shaft rotatably connected between the two sides of the housing, a stepper motor is mounted on the housing, and the output shaft end of the stepper motor is fixedly connected to the end of the spiral conveying shaft.

[0014] To further explain, the hydraulic oil cooling device for preventing overheating also includes heat dissipation copper fins fixed between the cooling pipes at even intervals, which are used to absorb heat from the cooling pipes.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The oil is discharged into four manifolds by an electric distributor. The circulation pump is started to discharge coolant into the cooling pipes through the upper liquid guide shell. The cooling pipes cool the coolant in the manifolds from the inside through the coolant. At the same time, some of the coolant in the cooling pipes flows into the cooling frame through the branch pipes. The cooling frame cools the coolant in the manifolds from the outside through the coolant. The cooled oil continues to flow to the right and is discharged through the oil outlet pipe. In this way, the oil can be cooled from both the inside and the outside at the same time, thereby improving the cooling effect of the oil.

[0017] 2. Under the action of the annular nozzle, whenever the cooling pipe and cooling frame cool the oil through the coolant, the annular nozzle can spray air to cool the cooling pipe and cooling frame, so as to prevent the cooling pipe and cooling frame from overheating due to the heat in the coolant, thereby ensuring the normal use effect of the cooling pipe and cooling frame.

[0018] 3. Under the action of the distribution assembly, whenever the internal temperature of one of the distribution tubes is high, the oil in the high-temperature distribution tube can be drawn into the low-temperature distribution tube through the electrically controlled liquid extraction tube and the electrically controlled liquid discharge tube, so that the oil in the distribution tube is balanced. This can prevent the oil in one part of the distribution tube from being too much and affecting the cooling effect, thereby ensuring that all four distribution tubes can be fully utilized to cool the oil.

[0033] Example: A hydraulic oil cooling device to prevent overheating; please refer to [link / reference]. Figures 1-9 As shown, the system includes a cylinder 1 and an oil inlet pipe 2 fixedly connected to the middle left side of the cylinder 1. An oil outlet pipe 3 is fixedly connected to the middle right side of the cylinder 1. A circular shell 4 is fixedly connected to the right end of the oil inlet pipe 2.

Guide plates 11 are fixedly connected to the front and rear sides of the distribution pipe 5 at even intervals. The guide plates 11 on the front and rear sides are staggered. The guide plates 11 can guide and block the oil so that the oil can be cooled by contacting the cooling pipe 7 for a long time. A circulation component is provided between the cylinder 1 and the cooling pipe 7. The circulation component is used to discharge coolant into the cooling pipe 7. Part of the coolant in the cooling pipe 7 is discharged into the cooling frame 6 through the branch pipe 10 and contacts the outer wall of the distribution pipe 5 so that the coolant can cool the oil from the inside and outside simultaneously through the cooling pipe 7 and the cooling frame 6. An air blowing component is provided on the cylinder 1. When the air blowing component is in operation, the air blowing component can achieve air cooling of the cooling pipe 7 and the cooling frame 6.

[0034] Please see Figure 4 As shown, the circulation assembly includes a liquid guide shell 8 and a circulation pump 9. Each set of cooling pipes 7 is connected between the top and bottom ends of the liquid guide shell 8. Three circulation pumps 9 are installed horizontally and evenly at intervals on the front side of the cylinder 1. The liquid outlet of the circulation pump 9 is connected to the front side of the upper liquid guide shell 8, and the liquid inlet of the circulation pump 9 is connected to the front side of the lower liquid guide shell 8.

[0035] Please see Figures 7-9As shown, the air blowing assembly includes an annular nozzle 12, a filter screen 121, an n-shaped frame 122, an air supply pump 123, a control valve 124, a three-way pipe 125, a switch valve I 126, a drive motor 127, and a filter assembly. Four filter screens 121 are fixedly connected at even intervals along the circumference on the left side of the cylinder 1. An annular nozzle 12 is fixedly connected along the circumference on the right side inside the cylinder 1. The annular nozzle 12 can spray air to cool the cooling pipe 7 and the cooling frame 6. An n-shaped frame 122 is fixedly connected to the upper part of the outer right side of the cylinder 1. Control valves 124 are installed at both outlet ends of the n-shaped frame 122. Control valves are located on both the front and rear sides. A three-way pipe 125 is connected between the bottom ends of 124. The air outlet of the three-way pipe 125 passes through the bottom right side of the cylinder 1 and connects to the bottom of the annular nozzle 12. A switch valve I 126 is rotatably connected to the inner center of the n-shaped frame 122. The channel of the switch valve I 126 is L-shaped. A drive motor 127 is installed on the upper part of the outer right side of the n-shaped frame 122. The output shaft end of the drive motor 127 is fixedly connected to the right end of the switch valve I 126. An air supply pump 123 is installed on the outer top right side of the cylinder 1. The air outlet of the air supply pump 123 is connected to the middle of the top of the n-shaped frame 122. The air supply pump 123 is connected to the switch valve I 126. A filter assembly is provided on the frame 122. When the filter assembly is in operation, it can filter impurities in the air. The filter assembly includes a switch valve II 128, a discharge pipe 129, a partition 1210, an electric filter cartridge 1211, a two-way air pump 1212, and a brush plate 1213. The discharge pipe 129 is symmetrically connected to the upper part of the n-shaped frame 122. The discharge pipe 129 can discharge impurities. The switch valve II 128 is rotatably connected to the upper part of the discharge pipe 129. The right end of the switch valve II 128 on both the front and rear sides is connected to the right side of the switch valve I 126 through a synchronous belt assembly. The channel of 28 is L-shaped. The n-shaped frame 122 has partitions 1210 fixedly attached to the front and rear sides, and an electric filter cylinder 1211 is installed between the two partitions 1210 on each side. The electric filter cylinder 1211 can filter impurities in the air. The top of the upper partition 1210 has a brush plate 1213 fixedly attached to it. The brush plate 1213 contacts the inner wall of the electric filter cylinder 1211. When the electric filter cylinder 1211 rotates, the brush plate 1213 can remove the impurities attached to the inner wall of the electric filter cylinder 1211. A bidirectional air pump 1212 is installed between the lower parts of the front and rear sides of the n-shaped frame 122.

[0036] Initially, the cooling frame 6, cooling pipe 7, and liquid guide shell 8 are all filled with an appropriate amount of coolant. The front switch valve II 128 is in the closed state, and the rear switch valve II 128 is in the open state. Switch valve I 126 is connected to the front of the n-shaped frame 122. First, the oil inlet pipe 2 and oil outlet pipe 3 are connected to hydraulic oil pipes. Then, the electric dispersing wheel 41 is started to reverse. When the oil is discharged into the oil inlet pipe 2, the oil is discharged into the circular shell 4 and contacts the electric dispersing wheel 41. The electric dispersing wheel 41 reverses and pushes the oil into the four diversion pipes 5, so that the oil flows in four parts. The oil in the diversion pipes 5 contacts the outer wall of the cooling pipe 7. At this time, the circulation pump 9 is started. The circulation pump 9 discharges the coolant in the upper liquid guide shell 8 into the cooling pipe 7. The coolant flows in the cooling pipe 7. 7. Coolant cools the oil in the distributor pipe 5 from the inside, absorbing and carrying away the heat from the oil. Simultaneously, some coolant in the distributor pipe 7 flows into the cooling frame 6 through the upper branch pipe 10. The coolant in the cooling frame 6 flows along the outer wall of the distributor pipe 5, thus cooling the oil from the outside. This allows for simultaneous cooling of the oil from both inside and outside, improving the cooling effect. The oil in the distributor pipe 5 also contacts the guide plate 11, which obstructs and guides the oil, causing it to remain in contact with the cooling pipe 7 for cooling. The guide plate 11 allows the oil to be cooled for a longer period, further improving the cooling effect. The cooled oil continues to flow to the right. The coolant that absorbs heat in the cooling pipe 7 is discharged through the oil outlet pipe 3 and then discharged into the lower liquid guide shell 8. The coolant that absorbs heat in the cooling frame 6 is discharged into the lower liquid guide shell 8 through the lower branch pipe 10. The coolant in the lower liquid guide shell 8 is then pumped away by the circulation pump 9 for recycling. This process is repeated to continuously cool the flowing oil. At the same time, the front control valve 124 is opened, and the air supply pump 123 is started. The air supply pump 123 discharges air into the n-shaped frame 122 through the switch valve I 126. The air in the n-shaped frame 122 is discharged into the front electric filter cartridge 1211. The front electric filter cartridge 1211 first filters impurities from the air. The air after filtering impurities passes through the front electric filter cartridge 1211 and is discharged into the front control valve 12. Inside the cylinder 1, the front control valve 124 discharges air into the annular nozzle 12 through the three-way pipe 125. The annular nozzle 12 sprays air into the cylinder 1, where it contacts the cooling pipe 7 and the cooling frame 6. The air cools the cooling pipe 7 and the cooling frame 6 to prevent them from overheating due to the heat in the coolant, thus ensuring their normal operation. After cooling the cooling frame 6, the air continues to flow to the left, passing through the filter screen 121 and being discharged. This process is repeated to continuously cool the cooling frame 6. When a large amount of impurities are filtered out on the front electric filter cylinder 1211, the front control valve 124 is closed, and the drive motor 127 is started to rotate the switch valve I 126 90 degrees clockwise.Switch valve I 126 rotates 90 degrees clockwise, ceasing communication with the front of n-shaped frame 122 and connecting with the rear of n-shaped frame 122. Simultaneously, the clockwise rotation of switch valve I 126 drives the clockwise rotation of switch valves II 128 on both sides via the synchronous belt assembly, opening the front switch valve II 128 and closing the rear switch valve II 128. Air pump 123 then discharges air into the rear of n-shaped frame 122 via switch valve I 126. The rear electric filter cartridge 1211 filters impurities in the air. The rear control valve 124 is activated, and air is discharged into the three-way pipe 125 through the rear control valve 124, which is then sprayed out through the annular nozzle 12 to provide air cooling for cooling pipe 7 and cooling frame 6. At this time, the front electric filter cartridge 1211 is activated to rotate, and the brush plate 1213 removes impurities adhering to the inner wall of the front electric filter cartridge 1211. The bidirectional air pump 121 is activated. 2. Air is discharged into the front side of the n-shaped frame 122, and then into the front electric filter cartridge 1211. The air blows the removed impurities upwards, and the upward-blown impurities are discharged into the front discharge pipe 129 through the front switch valve II 128. The front discharge pipe 129 discharges and collects the impurities. After the impurities on the inner wall of the front electric filter cartridge 1211 are cleaned, the front electric filter cartridge 1211 is closed, and then the bidirectional air pump 1212 is turned off. In this way, impurities in the electric filter cartridge 1211 can be cleaned without stopping the air cooling. When it is necessary to clean the impurities in the rear electric filter cartridge 1211, the above operation can be followed to clean and collect the impurities in the electric filter cartridge 1211. When no oil is discharged into the oil inlet pipe 2, the electric dispersion wheel 41, circulation pump 9, and air supply pump 123 can be turned off, and the coolant in the cooling pipe 7 and cooling frame 6 will stop flowing.

[0037] Please see Figure 10 and Figure 11As shown, the hydraulic oil cooling device for preventing overheating also includes a flow-dividing assembly installed between four flow-dividing pipes 5. The flow-dividing assembly includes a temperature sensor 13, a housing 131, an electrically controlled drain pipe 132, an electrically controlled suction pipe 133, and a conveying assembly. The housing 131 is installed between the left sides of the four flow-dividing pipes 5. Four electrically controlled drain pipes 132 are evenly spaced along the circumference of the left side of the housing 131, with their tail ends connected to the left sides of the four flow-dividing pipes 5 respectively. Four electrically controlled suction pipes 133 are evenly spaced along the circumference of the right side of the housing 131, with their tail ends connected to the left sides of the four flow-dividing pipes 5 respectively. The electrically controlled suction pipes 133 can... The system allows a portion of the oil in the diversion pipe 5 to be drawn into the housing 131. Two temperature sensors 13 are installed on the left side of each of the four diversion pipes 5. The temperature sensors 13 are electrically connected to the electrically controlled drain pipe 132 and the electrically controlled suction pipe 133 through a control module. A conveying assembly is provided on the housing 131. When the conveying assembly is in operation, it can drive the oil to move to the left for conveying. The conveying assembly includes a spiral conveying shaft 134 and a stepper motor 135. The spiral conveying shaft 134 is rotatably connected between the left and right sides of the housing 131. The stepper motor 135 is installed on the outer right side of the housing 131. The output shaft end of the stepper motor 135 is fixedly connected to the right end of the spiral conveying shaft 134.

[0038] When the oil is discharged into the four distribution pipes 5, the temperature sensor 13 monitors the temperature inside the four distribution pipes 5. When the temperature of one of the distribution pipes 5 exceeds the set maximum value, the corresponding temperature sensor 13 controls the electrically controlled suction pipe 133 on the distribution pipe 5 with the higher internal temperature and the electrically controlled drain pipe 132 on the distribution pipe 5 with the lower internal temperature to start through the control module. The electrically controlled suction pipe 133 draws part of the oil in the distribution pipe 5 with the higher internal temperature into the housing 131. The oil in the housing 131 then flows into the spiral conveyor shaft 1. Upon contact with stepper motor 135, the spiral conveyor shaft 134 rotates. This rotation causes the oil inside housing 131 to move to the left. The oil then flows through electrically controlled drain pipe 132 into the cooler internal distribution pipe 5. When the temperature inside the distribution pipe 5 drops to the standard value, temperature sensor 13, via the control module, closes the corresponding electrically controlled drain pipe 132 and electrically controlled suction pipe 133, shutting off stepper motor 135 and stopping the spiral conveyor shaft 134 from rotating. This prevents excessive oil in some of the distribution pipes 5 from affecting the cooling effect, ensuring that all four distribution pipes 5 are fully utilized for oil cooling.

[0039] Please see Figure 12 As shown, the hydraulic oil pipe cooling device for preventing overheating also includes heat dissipation copper fins 14. Multiple heat dissipation copper fins 14 are fixedly connected at even intervals between the three sets of cooling pipes 7. The heat dissipation copper fins 14 can absorb the heat on the cooling pipes 7 to complete the heat dissipation of the cooling pipes 7.

[0040] When the cooling pipe 7 cools the oil in the distributor pipe 5 through the coolant, the heat dissipation copper fins 14 can absorb and dissipate the heat on the cooling pipe 7, thereby further dissipating heat from the cooling pipe 7 and improving the performance of the cooling pipe 7.
