DETAILED DESCRIPTION
[0024] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0025] Please refer to Figures 1-4 An embodiment provided by the utility model:
[0026] The base 1 and the box 13 used in the application are products that can be directly purchased in the market, and their principles and connection modes are all prior art known to those skilled in the art, so they will not be described here.
[0027] A kind of refining machine gear box, comprising: base 1, the upper side of base 1 is fixedly installed with box 13 by bolt;
[0028] The top surface of the base 1 has an installation cavity 11, the top surface of the base 1 is covered with a sealing gasket 12, and the top surface of the box 13 has a storage groove 14.
[0029] A cooling structure 2 is installed on the inner side of the base 1. The cooling structure 2 includes a first heat-conducting plate 21, which is movably installed on the inner side of the mounting cavity 11. A second heat-conducting plate 22 is provided on the bottom surface of the first heat-conducting plate 21. An inlet pipe 23 and an outlet pipe 24 are fixedly connected to the back of the base 1. By staggering the second heat-conducting plates 22, the coolant entering the mounting cavity 11 through the inlet pipe 23 can flow out through the outlet pipe 24 along a fixed trajectory under the restriction of the second heat-conducting plates 22. This reduces the residence time of the coolant inside the mounting cavity 11 and quickly carries away the heat from the lubricating oil in the housing 13 while flowing out quickly, improving the cooling effect on the lubricating oil and ensuring a good user experience.
[0030] A lifting structure 3 is installed on the housing 13. The lifting structure 3 includes a limiting disc 31. The limiting disc 31 is slidably installed inside the storage slot 14. A fixing block 32 is fixedly connected to the top surface of the limiting disc 31. A circular lifting groove 33 is opened on the surface of the fixing block 32.
[0031] Furthermore, the top edge of the first heat-conducting plate 21 contacts the bottom surface of the sealing gasket 12. The sealing gasket 12 is located between the base 1 and the housing 13. The sealing gasket 12 can separate the mounting cavity 11 and the inner side of the housing 13 from the position of the first heat-conducting plate 21, thus preventing the coolant in the mounting cavity 11 and the lubricating oil in the housing 13 from leaking out.
[0032] Furthermore, the upper end of the first heat-conducting plate 21 is located inside the housing 13, and the second heat-conducting plate 22 is located inside the mounting cavity 11. The heat from the lubricating oil inside the housing 13 can be transferred to the coolant inside the mounting cavity 11 through the first heat-conducting plate 21.
[0033] Furthermore, the upper end of the second heat-conducting plate 22 is parallel to that of the first heat-conducting plate 21. The second heat-conducting plate 22 is installed in a front-to-back manner and is symmetrical about the center line of the first heat-conducting plate 21. The coolant flowing into the mounting cavity 11 through the liquid inlet pipe 23 can flow to both sides in a fixed trajectory under the guidance of the second heat-conducting plate 22 so as to be quickly discharged through the liquid outlet pipe 24. This avoids the coolant from accumulating in the mounting cavity 11 for a long time, which would result in the heat not being dissipated in time and reduce the user experience of the device.
[0034] Furthermore, both the inlet pipe 23 and the outlet pipe 24 are connected to the inside of the mounting cavity 11. There are two sets of outlet pipes 24, located on both sides of the inlet pipe 23. Coolant can be introduced into the mounting cavity 11 through the inlet pipe 23, and coolant in the mounting cavity 11 can also flow out through the outlet pipe 24.
[0035] Furthermore, the fixing block 32 is housed inside the storage slot 14, and the top surface of the fixing block 32 is flush with the top surface of the box 13. The flat top surface of the box 13 can prevent damage to the hoisting structure 3 and extend its service life.
[0036] Working principle: During use, the heat generated by the internal components of the housing 13 during operation is transferred to the lubricating oil inside the housing 13. The heat of the lubricating oil is transferred to the second heat-conducting plate 22 through the first heat-conducting plate 21. The coolant is introduced into the inner side of the mounting cavity 11 through the liquid inlet pipe 23, which can remove the heat on the second heat-conducting plate 22 and achieve the cooling function. The coolant entering the mounting cavity 11 can flow to both sides in a fixed trajectory under the guidance of multiple sets of second heat-conducting plates 22, so as to be quickly discharged through the liquid outlet pipe 24. This avoids the coolant from accumulating in the mounting cavity 11 for a long time, which would result in the heat not being dissipated in time and reduce the user experience of the device.
[0037] The fixed rectangular block 32 is stored inside the storage groove 14, and the top surface of the circular lifting groove 33 is flush with the top surface of the box 13, making the top surface of the box 13 flat, which can prevent the lifting structure 3 from being damaged and extend its service life. When in use, the circular lifting groove 33 is pulled out from the storage groove 14, so that the upper end of the fixed rectangular block 32 is exposed on the top surface of the box 13, and the limiting disc 31 will be locked inside the storage groove 14, which makes it easy to lift the device through the circular lifting groove 33.
[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
