DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figure 1 The utility model relates to a composite EMU total air drainage and hollow shaft grinding device, comprising a detachable shaft 100, a driving device 300 connected to one end of the detachable shaft 100, a touch screen 200 arranged on the driving device 300, and a functional part arranged at the other end of the detachable shaft 100; the driving device 300 is controlled by the touch screen 200, and the detachable shaft 100 drives the functional part to rotate under the drive of the driving device 300 to complete the set function.

[0031] The removable shaft 100, as the main body of the device, not only has sufficient strength and stability, but also is designed with a quick disassembly structure, which is convenient for replacing different functional parts according to actual needs. Therefore, the removable shaft 100 is movably connected with the driving device 300 and the functional parts. The removable shaft 100 is a vertical rod made of high-speed steel.

[0032] The driving device 300 is controlled by the touch screen 200 to realize the forward and reverse rotation of the functional part. The touch screen 200 is used as an interface for the user to interact with the device. The user can set the working mode, control the start and stop of the driving device 300, and monitor the working status of the device through the touch screen 200.

[0033] The driving device 300 provides rotational power for the removable shaft 100. The driving device 300 uses a high-precision motor, and transmits the rotational power of the motor to the removable shaft 100 through a reducer and a transmission mechanism, thereby driving the functional part to rotate.

[0034] There are two types of functional parts. You can choose the total air drainage tool or the hollow shaft grinding tool according to actual needs. When the total air drainage tool is selected, the device can be used for the total air drainage operation of the EMU; when the hollow shaft grinding tool is selected, the device can be used for the hollow shaft grinding operation of the EMU, specifically:

[0035] When performing the drain function, please refer to Figure 2 , the functional part is the main air cylinder drainage assembly 400.

[0036] Please refer to Figure 3 , Figure 4 and Figure 8 The main air cylinder drainage assembly 400 includes an arc-shaped buckle 410 and a docking base 420. The arc-shaped buckle 410 is a structure for fixing and adapting the main air cylinder drainage valve of a standard EMU. Its design feature is that it includes two arc-shaped metal baffles 4101, which are symmetrically fixedly arranged on both sides of the upper end surface of the docking base 420. The curvature of the arc-shaped metal baffle 4101 matches the shape of the main air cylinder drainage valve, ensuring that it can fit tightly on the valve, thereby achieving stable fixation and operation of the drainage valve opening and closing.

[0037] The docking base 420 is a component used to connect the arc buckle 410 and the removable shaft 100. Its design feature is that the lower end surface is provided with a groove 4201, and the size and shape of the groove match the end of the removable shaft 100. When drainage work is required, the end of the removable shaft 100 can be embedded in the groove 4201 of the docking base.

[0038] In actual application, the operator first selects a suitable main air cylinder drainage assembly 400 according to the model of the EMU and the size of the main air cylinder drainage valve. Then, the end of the removable rod 100 is embedded in the groove 4201 of the docking base 420, and the arc-shaped metal baffle 4101 of the arc-shaped buckle 410 is aligned and tightly fitted on the drainage valve to ensure stable fixation. Finally, the drainage operation is controlled by operating the touch screen 200.

[0039] When performing the grinding function, please refer to Figure 5 , the functional part is a hollow shaft grinding assembly 500.

[0040] Please refer to Figure 6 and Figure 7 The hollow shaft grinding assembly 500 includes a grinding wheel 510 and a grinding groove 520 fixedly arranged on one side of the grinding wheel. The grinding wheel 510 is a main component of the grinding operation, and its material and shape are optimized and designed according to the actual situation of the hollow shaft to ensure the grinding effect.

[0041] The grinding groove 520 is a component that connects the grinding wheel 510 and the removable shaft 100. Therefore, the shape and size of the grinding groove 520 match the end of the removable shaft 100. When the hollow shaft grinding operation is required, the grinding groove 520 of the grinding wheel 510 is first aligned with the end of the removable shaft 100, and then the two are nested and connected.

[0042] In a specific application, a suitable hollow shaft grinding assembly 500 is selected according to the actual situation of the hollow shaft; the grinding groove 520 is aligned with the end of the removable shaft 100 for nested connection; the grinding parameters such as grinding speed and grinding depth are set through the touch screen 200; the driving device 300 is started to control the removable shaft 100 to rotate, driving the grinding wheel 510 to perform grinding operations; during the grinding process, the grinding wheel 510 contacts the surface of the hollow shaft while rotating, thereby achieving the grinding of the hollow shaft. After the grinding is completed, the driving device 300 is turned off, the connection between the grinding wheel 510 and the removable shaft 100 is disconnected, and the hollow shaft grinding assembly 500 is removed for cleaning and maintenance.

[0043] In order to reduce environmental pollution, a dust collection device can also be arranged around the grinding wheel. The dust collection device includes an annular dust hood arranged circumferentially of the grinding wheel, a hose connected to the annular dust hood, a vacuum pump fixed on a removable rod, and a waste chip collection box; the annular dust hood is made of flexible material and can automatically adjust its shape according to the grinding position; the hose is a telescopic hose, one end of which is connected to the annular dust hood and the other end is connected to the air inlet of the vacuum pump; the air outlet of the vacuum pump is connected to the air inlet of the waste chip collection box, and the waste chip collection box is provided with a detachable filter.

[0044] When the waste chip collection system is working, the vacuum pump generates negative pressure, and the dust and waste chips generated during the grinding process are sucked into the annular dust collection cover through the hose, and then transported to the waste chip collection box through the hose; the waste chips are blocked by the filter in the collection box, and clean air is discharged from the air outlet of the collection box. It can effectively collect the waste chips generated during the grinding process, reduce environmental pollution, and improve the cleanliness and safety of the working environment.

[0045] Please refer to Fig. 9 A bearing seat 600 is also slidably provided on the removable shaft 100, and the bearing seat 600 can rotate relative to the removable shaft 100 and can slide on the removable shaft 100. The bearing seat 600 is placed at a specific position on the removable shaft 100 according to the on-site construction conditions.

[0046] It will be easily understood by those skilled in the art that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
