Description

Technical Field

[0001] This utility model relates to the field of hydraulic transmission technology, and in particular to a self-cooling oil tank and filling pump hydraulic system. Background Technology

[0002] The filling pump hydraulic system uses hydraulic oil as the working medium. With the help of hydraulic pumps and pipelines, the hydraulic oil is delivered to hydraulic equipment such as hydraulic cylinders or hydraulic motors to realize the conversion of hydraulic energy into mechanical energy.

[0003] During the use of the filling pump hydraulic system, an oil tank is usually used to store hydraulic oil. Since the hydraulic oil generates heat when it is working, the hydraulic oil in the tank needs to be cooled when the filling pump hydraulic system is working. However, at present, the oil tank mainly relies on radiators or condensers for cooling, which requires the arrangement of circulation pipelines and corresponding equipment, resulting in a complex cooling structure and high operating costs.

[0004] Therefore, it is necessary to provide a self-cooling oil tank and a filling pump hydraulic system to solve the above-mentioned technical problems. Utility Model Content

[0005] To address the technical problem that existing oil tanks used in filling pump hydraulic systems have complex heat dissipation structures and high operating costs, this utility model provides a self-cooling oil tank and a filling pump hydraulic system.

[0006] The self-cooling oil tank provided by this utility model includes: an oil tank; multiple heat dissipation fins disposed on the outer wall of the oil tank by means of heat dissipation adhesive, wherein the multiple heat dissipation fins are all used to dissipate heat from the hydraulic oil in the oil tank; an oil return port and two oil outlet ports disposed on the oil tank.

[0007] Preferably, all of the heat sinks are fixedly mounted on the oil tank by bolts.

[0008] Preferably, an oil drain pipe is fixedly installed at the bottom of the oil tank, and a valve is provided on the oil drain pipe.

[0009] This utility model also provides a filling pump hydraulic system, including: a support frame fixedly installed on the oil tank; a three-way pipe fixedly installed on the oil return port; and two pumping mechanisms mounted on the support frame for conveying hydraulic oil.

[0010] Preferably, the pumping mechanism includes: a hydraulic pump fixedly mounted on the support frame, an oil suction pipe fixedly mounted on the oil suction end of the hydraulic pump, one end of the oil suction pipe being fixedly connected to the oil outlet; a first connecting pipe fixedly mounted on the oil discharge end of the hydraulic pump, a first flexible hose fixedly mounted on one end of the first connecting pipe, a delivery pipe fixedly mounted on one end of the first flexible hose, a second connecting pipe fixedly mounted on the delivery pipe, a second flexible hose fixedly mounted on one end of the second connecting pipe, and one end of the second flexible hose being fixedly connected to one end of the three-way pipe.

[0011] Preferably, a one-way valve is provided on the first through pipe, and a solenoid valve is provided on the second through pipe.

[0012] Compared with related technologies, the self-cooling oil tank and filling pump hydraulic system provided by this utility model have the following beneficial effects: This invention provides a self-cooling oil tank and a filling pump hydraulic system. Through the use of multiple heat sinks, it can simultaneously absorb heat conducted by the hydraulic oil and transfer the heat from the oil tank to itself via thermal conduction. Finally, the heat sinks transfer the heat to the air, achieving heat dissipation for the hydraulic oil. Since thermal adhesive is filled between the heat sinks and the oil tank, the heat dissipation efficiency and area of ​​the oil tank are further increased. The heat dissipation structure is relatively simple and has low operating costs. Bolts can be used to not only fix the heat sinks but also to remove them from the oil tank, allowing for the replacement of the thermal adhesive between the heat sinks and the oil tank. Through the coordinated use of two pumping mechanisms, the filling pump hydraulic system can deliver hydraulic oil to the hydraulic equipment used, such as a hydraulic cylinder, enabling the output rod of the hydraulic cylinder to extend and retract.

[0016] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a self-cooling oil tank and a filling pump hydraulic system, such as Figure 1-5 As shown, the self-cooling oil tank includes: an oil tank 1; multiple heat dissipation fins 2 disposed on the outer wall of the oil tank 1 by means of heat dissipation adhesive, the multiple heat dissipation fins 2 being used to dissipate heat from the hydraulic oil in the oil tank 1; an oil return port 4 and two oil outlet ports 3 disposed on the oil tank 1.

[0018] The multiple heat sinks 2 are all fixedly mounted on the oil tank 1 by bolts.

[0019] An oil drain pipe is fixedly installed at the bottom of the oil tank 1, and a valve is installed on the oil drain pipe.

[0020] During use, the hydraulic oil circulates through the filling pump hydraulic system and then flows back to the oil tank 1 through the return port 4. The oil tank 1 absorbs the heat conducted by the hydraulic oil through multiple heat sinks 2. The heat sinks 2 are of different sizes and are located at the top, bottom, left, right, front, and back of the oil tank 1. The metal material of the heat sinks 2 transfers the heat of the hydraulic oil from the oil tank 1 to itself through heat conduction. Finally, the multiple heat sinks 2 transfer the heat to the air, thus cooling the hydraulic oil. Since the heat sinks 2 are filled with heat-dissipating adhesive between them and the oil tank 1, the heat dissipation efficiency and area of ​​the oil tank 1 are further increased. When maintenance is required, the hydraulic oil can be drained by opening the valve on the drain pipe for replacement. When the heat-dissipating adhesive needs to be replaced, the heat sinks 2 can be removed from the oil tank 1 by removing the bolts, and then the heat-dissipating adhesive between the heat sinks 2 and the oil tank 1 can be replaced.

[0021] This utility model also provides a filling pump hydraulic system, including: a support frame 5 fixedly installed on the oil tank 1; a three-way pipe 6 fixedly installed on the oil return port 4; and two pumping mechanisms assembled on the support frame 5 for conveying hydraulic oil.

[0022] The pumping mechanism includes: a hydraulic pump 7 fixedly installed on the support frame 5, an oil suction pipe 8 fixedly installed on the oil suction end of the hydraulic pump 7, one end of the oil suction pipe 8 being fixedly connected to the oil outlet 3; a first connecting pipe 9 fixedly installed on the oil discharge end of the hydraulic pump 7, a first flexible hose 10 fixedly installed on one end of the first connecting pipe 9, a delivery pipe 11 fixedly installed on one end of the first flexible hose 10, a second connecting pipe 12 fixedly installed on the delivery pipe 11, a second flexible hose 13 fixedly installed on one end of the second connecting pipe 12, and one end of the second flexible hose 13 being fixedly connected to one end of the three-way pipe 6.

[0023] A one-way valve 14 is provided on the first through pipe 9, and a solenoid valve 15 is provided on the second through pipe 12.

[0024] In operation, the filling pump hydraulic system connects two delivery pipes 11 to the two hydraulic ends of the hydraulic cylinder. Then, one of the hydraulic pumps 7 is started. The hydraulic pump 7 delivers hydraulic oil to the first hose 10 through the suction pipe 8 and the first connecting pipe 9. The first hose 10 then delivers the hydraulic oil to the delivery pipe 11, and finally into the hydraulic cylinder, causing the output rod of the hydraulic cylinder to extend. Because the first connecting pipe 9 is equipped with a check valve 14, it prevents hydraulic oil from flowing back into the hydraulic pump 7. Next, the currently started hydraulic pump 7 is shut off, and the corresponding solenoid valve 15 is opened. Then, the other hydraulic pump is started. 7. Another hydraulic pump 7 delivers hydraulic oil to the hydraulic cylinder in the same way, causing the output rod of the hydraulic cylinder to retract. During the retraction process, the hydraulic oil delivered previously will flow back into the delivery pipe 11, then enter the second hose 13 through the second pipe 12, then enter the three-way pipe 6 through the second hose 13, and then enter the oil tank 1 through the return port 4. Then, the solenoid valve 15 that was opened at this time is closed, and another solenoid valve 15 is opened. Then, the hydraulic pump 7 that was opened at this time is closed, and the hydraulic pump 7 that was started earlier is started, so that the hydraulic cylinder can perform the next extension and retraction movement, and so on continuously.
