Description

Technical Field

[0001] This utility model relates to the field of hydraulic cylinder technology, and in particular to a hydraulic cylinder with a cooling and temperature reduction structure. Background Technology

[0002] A hydraulic cylinder is a device that converts hydraulic energy into mechanical energy. It is a cylindrical metal component that mainly guides the piston to perform linear reciprocating motion within the cylinder. Typically, a cooling structure is needed to dissipate the heat generated during the operation of a hydraulic cylinder.

[0003] A search revealed a Chinese patent (authorization announcement number: CN221628560U), which includes a hydraulic cylinder body and a cooling component. A sliding rod is slidably connected to the inner wall of the left end of the hydraulic cylinder body for cooling. The cooling component is installed on the outer wall of the middle end of the hydraulic cylinder body. The cooling component includes a first heat sink, a U-shaped tube, a water inlet pipe, a return pipe, and a telescopic corrugated pipe. The inner wall of the first heat sink is covered with a U-shaped tube, with the water inlet pipe connected to the beginning of the U-shaped tube. The return pipe is fixedly connected to the end of the U-shaped tube, and a telescopic corrugated pipe is connected to the middle end of the U-shaped tube. A second heat sink is connected to the end of the telescopic corrugated pipe, and the second heat sink has an overall arc-shaped structure. This hydraulic cylinder with a cooling and temperature-reducing structure can not only cool the hydraulic cylinder body during use but also be installed on hydraulic cylinder bodies of different sizes.

[0004] In practical applications, this patented technology can cool and dissipate heat from hydraulic cylinders to improve their performance. However, during use, the above solution supplies coolant to the U-shaped tube via an external water tank. The connection between the external water tank and the U-shaped tube must be compatible, requiring significant time to find a suitable tank. Furthermore, most external water tanks lack a mechanism for cooling the coolant, affecting its cooling effect on the hydraulic cylinder. Additionally, the first and second heat sinks in this solution have a certain curvature because they need to fit against the hydraulic cylinder. Since the curvature varies depending on the diameter of the hydraulic cylinder, and the two ends of the hydraulic cylinder are usually fixed, this solution prevents the installation or removal of cooling components once the cylinder is fixed. Therefore, this solution is unsuitable for hydraulic cylinders of different sizes, significantly reducing the device's practicality. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figure 1-9This utility model provides an embodiment of a hydraulic cylinder with a cooling and temperature reduction structure, comprising a hydraulic cylinder body 1. The cylinder body 1 is characterized by having main elastic steel plates A2 and B3 on both upper sides, and secondary elastic steel plates A4 and B5 on both lower sides. Water bags 6 are fixedly connected to the inner sides of the main elastic steel plates A2, B3, A4, and B5, storing circulating coolant. The other side of the water bags 6 is in contact with the hydraulic cylinder body 1. A circulation mechanism 7 is provided at one end of the hydraulic cylinder body 1. A fixing mechanism 8 is provided on the main elastic steel plate A2. Corrugated pipes 9 are provided on both the main elastic steel plates A2 and B3, penetrating the main elastic steel plates A2 and B3. The elastic steel sheet B3 is connected to the water bag 6 inside it. Corrugated pipes 9 and connecting pipes 10 are provided on the secondary elastic steel sheets A4 and B5, and they pass through the secondary elastic steel sheets A4 and B5 to connect to the water bag 6 inside them. The corrugated pipes 9 are used to connect the corrugated pipes 9 between the water bags 6. The other end of the corrugated pipe 9 is fitted with a connecting nut 11. The connecting nut 11 is used to connect the corrugated pipe 9 and the connecting pipe 10. The corrugated pipe 9 on the main elastic steel sheet A2 is threadedly connected to the connecting pipe 10 on the secondary elastic steel sheet A4 through the connecting nut 11. The corrugated pipe 9 on the secondary elastic steel sheet A4 is threadedly connected to the connecting pipe 10 on the secondary elastic steel sheet B5 through the connecting nut 11. The corrugated pipe 9 on the secondary elastic steel sheet B5 is threadedly connected to the connecting pipe 10 on the main elastic steel sheet B3 through the connecting nut 11.

[0030] The circulation mechanism 7 includes a liquid storage tank 71, a circulation pump 72, a semiconductor refrigerator 73, and a circulation pipe 74. The liquid storage tank 71 is located at one end of the hydraulic cylinder body 1. The circulation pump 72 is fixedly connected to the liquid storage tank 71. The input end of the circulation pump 72 extends through the liquid storage tank 71 to its lower interior. The output end of the circulation pump 72 extends through the main elastic steel sheet B3 and is connected to the water bag 6 inside it. The semiconductor refrigerator 73 is located on the inner wall of the liquid storage tank 71. One side of the semiconductor refrigerator 73 extends through the liquid storage tank 71 and is fixedly connected to it. One end of the circulation pipe 74 extends through the main elastic steel sheet A2 and is connected to the water bag 6 inside it. The other end of the circulation pipe 74 is connected to the liquid storage tank 71.

[0031] Through the above technical solution, by setting up a circulation mechanism 7, the coolant inside the liquid storage tank 71 is cooled down by starting the semiconductor refrigerator 73, and the coolant inside the liquid storage tank 71 is pumped into the water bag 6 by the circulation pump 72. In addition, multiple water bags 6 are connected by corrugated pipes 9, connecting pipes 10 and connecting nuts 11, so that the coolant can circulate between the water bags 6 and the liquid storage tank 71, thereby increasing the heat dissipation and cooling effect on the hydraulic cylinder.

[0032] Specifically, the fixing mechanism 8 includes a snap-fit ​​block 81, a rubber band 82, a plug rod 83, a connecting plate 84, and a pull-back spring 85. The snap-fit ​​block 81 is fixedly connected to one side above the main elastic steel sheet A2. One end of the rubber band 82 is fixedly connected to the other side above the main elastic steel sheet A2. Several adjustment holes 12 are provided on the rubber band 82. One end of the plug rod 83 passes through the snap-fit ​​block 81 and is movably connected to it. One end of the plug rod 83 passes through the rubber band 82 through the adjustment holes 12. The connecting plate 84 is sleeved on the other end of the plug rod 83. The pull-back spring 85 is disposed between the snap-fit ​​block 81 and the connecting plate 84. Both ends of the pull-back spring 85 are fixedly connected to the snap-fit ​​block 81 and the connecting plate 84, respectively.

[0033] Through the above technical solution, by pulling the insertion rod 83 to overcome the force of the return spring 85, the insertion rod 83 is pulled upwards. After the rubber band 82 is wrapped around the secondary elastic steel sheet A4, secondary elastic steel sheet B5 and main elastic steel sheet B3, it is inserted into the snap-fit ​​block 81 and pulled tight. Since the elastic steel sheet is plastic, it can deform according to the curvature of the hydraulic cylinder during the tightening process, so that the water bag 6 can fit more tightly against the hydraulic cylinder. Then, the insertion rod 83 is released and, under the action of the return spring 85, the insertion rod 83 is inserted into the adjustment hole 12 on the rubber band 82, thereby fixing the water bag 6 inside the main elastic steel sheet A2, main elastic steel sheet B3, secondary elastic steel sheet A4 and secondary elastic steel sheet B5. By adding or removing the secondary elastic steel sheet A4 and secondary elastic steel sheet B5, it can be applied to hydraulic cylinders of various sizes.

[0034] Specifically, a protective shell 14 is provided on one side of the semiconductor refrigerator 73. One side of the protective shell 14 is fixedly connected to the liquid storage tank 71, and a cooling fan 13 is fixedly connected to the other side of the inner side of the protective shell 14.

[0035] Through the above technical solution, by setting up a protective shell 14 and a cooling fan 13, since the semiconductor refrigerator 73 generates heat when it is working, the cooling fan 13 can be activated to dissipate heat from the semiconductor refrigerator 73, and the protective shell 14 protects the semiconductor refrigerator 73 and the cooling fan 13.

[0036] Specifically, a partition plate 15 is provided in the middle of the interior of the liquid storage tank 71, and the partition plate 15 is fixedly connected to the liquid storage tank 71.

[0037] Through the above technical solution, by setting the partition plate 15, the liquid storage tank 71 can be divided, so that the water flowing into the liquid storage tank 71 from the circulation pipe 74 can only flow to the other side of the liquid storage tank 71 after passing through the semiconductor refrigerator 73, thereby cooling the cooling water after the hydraulic cylinder heats up.

[0038] Specifically, a sealing gasket 16 is provided between the other end of the bellows 9 and the other end of the connecting pipe 10, and the sealing gasket 16 is fixedly connected to the other end of the bellows 9.

[0039] By using the above technical solution, the sealing gasket 16 can be used to seal the bellows 9 and the connecting pipe 10, thus preventing coolant from leaking between the bellows 9 and the connecting pipe 10.

[0040] Specifically, both the output end of the circulation pump 72 and the circulation pipe 74 are equipped with flexible and telescopic connecting pipes.

[0041] With the above technical solution, since the installation position and angle of the hydraulic cylinder need to be changed according to the use, the above settings can be used to select a suitable position to install the reservoir 71 according to the specific installation position and angle of the hydraulic cylinder.

[0042] Working principle: In use, first, select the number of secondary elastic steel plates according to the size of the hydraulic cylinder. Then, attach the main elastic steel plate A2, main elastic steel plate B3, secondary elastic steel plate A4, and secondary elastic steel plate B5 to the surface of the hydraulic cylinder. Next, pull the insertion rod 83 to overcome the force of the return spring 85, causing the insertion rod 83 to be pulled upwards. After wrapping the rubber band 82 around the secondary elastic steel plate A4, secondary elastic steel plate B5, and main elastic steel plate B3, insert it into the snap-fit ​​block 81 and pull it tight. Because the elastic steel plate has plasticity, it can deform according to the curvature of the hydraulic cylinder during the tightening process, so that the water bag 6 can fit more tightly against the hydraulic cylinder. Then, release the insertion rod 83. Under the action of the return spring 85, the insertion rod 83 is inserted into the adjustment hole 12 on the rubber band 82, thereby adjusting the main elastic steel plate A2, main elastic steel plate B3, and main elastic steel plate B5. The water bags 6 inside the secondary elastic steel plates A4 and B5 are fixed. Then, the corrugated pipes 9 and connecting pipes 10 on the main elastic steel plates A2, B3, A4, and B5 are connected in series, so that the coolant can circulate in the multiple water bags 6 and the reservoir 71. Then, the coolant is added into the reservoir 71 by opening the filling port on the reservoir 71. Then, the semiconductor refrigerator 73 and the circulation pump 72 are started. The semiconductor refrigerator 73 cools down the coolant in the reservoir 71, and the circulation pump 72 draws the coolant in the reservoir 71 into the water bags 6. The multiple water bags 6 are connected by the corrugated pipes 9, connecting pipes 10 and connecting nuts 11, so that the coolant can circulate in the water bags 6 and the reservoir 71 to dissipate heat and cool the hydraulic cylinder. Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
