Detailed Implementation

[0019] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0020] Example 1

[0021] like Figure 1 and Figure 2 As shown, Figure 1 This is a three-dimensional structural view of the automatic sand-adding device for the high-speed train. Figure 2 This is an internal structural view of the automatic sand-adding device for the EMU.

[0022] The automatic sand-adding device for high-speed trains of this utility model includes a housing 1, an operation panel 2, a power supply 3, a vacuum dust collection device 4, a sand box 5, and a blower 6. The power supply 3, the vacuum dust collection device 4, the sand box 5, and the blower 6 are all located inside the housing 1. The operation panel 2 is fixedly mounted on the outer wall of the housing 1. The power supply 3 is connected to the operation panel 2, the vacuum dust collection device 4, and the blower 6 to provide power. The operation panel 2 is also connected to the vacuum dust collection device 4 and the blower 6 to observe and control the sand-adding process in real time. The bottom of the sand box 5 is connected to a sand-adding pipeline 8 via a pipeline sealing joint 7. The end of the pipe 8 extends from the inside of the housing 1 to the outside of the housing 1 and is sealed to the sand filling port of the EMU through the sand filling port sealing joint 9, so as to transport the sand in the sand box 5 to the sand spreading system of the EMU. The blower 6 is connected to the sand delivery pipe 8 to provide the power for transporting the sand. The vacuum dust collection device 4 is connected to the sand filling port sealing joint 9 through the dust collection pipe 10. The sand delivery pipe 8 is set inside the dust collection pipe 10. A dust collection channel is formed between the outer wall of the sand delivery pipe 8 and the inner wall of the dust collection pipe 10. The vacuum dust collection device 4 forms a negative pressure at the sand filling port sealing joint 9 to absorb and clean the smoke and dust generated during sand filling.

[0023] like Figure 3 As shown, Figure 3This is a structural view of the sand filling port sealing joint. Preferably, the sand filling port sealing joint 9 is provided with a filter cover plate 11, and the sand delivery pipe 8 is disposed inside the filter cover plate 11. One end of the filter cover plate 11 is fixedly disposed on the sand filling port sealing joint 9, and the other end is fixedly disposed on the sand delivery pipe 8 through an end plate 12. The flow gap between the filter cover plate 11 and the sand delivery pipe 8 communicates with the dust suction channel. The filter cover plate 11 is provided with a plurality of filter holes. When the sand delivery pipe 8 adds sand to the sand filling port of the train set, the dust generated by adding sand enters the flow gap through the filter holes and is discharged into the vacuum dust collection device 4 through the dust suction channel.

[0024] Preferably, the bottom of the chassis 1 is provided with a pulley 13 and a support base 14. The pulley 13 is used to drive the chassis 1 to move as a whole, and the support base 14 is used to fix the chassis 1 in a suitable position.

[0025] A handle 15 is provided on the top of the chassis 1 to facilitate the disassembly of the upper wall panel of the chassis 1, which facilitates the installation and maintenance of the components inside the chassis 1, and also facilitates the movement of the chassis 1.

[0026] Preferably, a flow sensor is installed on the sand delivery pipeline 8 to detect the amount of sand delivered from the sand delivery pipeline 8 to the sand filling port of the train set. The flow sensor is connected to the operation panel 2.

[0027] The operation panel 2 is equipped with a start button, a stop button, an emergency stop button, a sand quantity setting button, and a fault indicator light. The operation panel 2 also contains a control module. The start button, stop button, emergency stop button, sand quantity setting button, and fault indicator light are all connected to the control module. The control module is connected to the vacuum cleaning device 4 and the blower 6. The start button, stop button, and emergency stop button control the start and stop of the vacuum cleaning device 4 and the blower 6. The sand quantity setting button sets the required amount of sand to be added, and the flow sensor detects the real-time amount of sand added. When the real-time sand quantity reaches the set amount, the control module stops the vacuum cleaning device 4 and the blower 6.

[0028] If a malfunction occurs during the sand adding process, such as a power supply 3 failure, sensor failure, or motor overload, the control module will issue an alarm signal and stop the equipment from operating. If the vacuum dust collection device 4 and the blower 6 are started, but the flow sensor does not detect that sand is being transported, the fault indicator light will be controlled to issue a fault warning.

[0029] A partition plate 16 is provided inside the chassis 1, which divides the interior of the chassis 1 into an electrical control cavity and an equipment cavity. The power supply 3 is located in the electrical control cavity, and the operation panel 2 is located above the power supply 3. The vacuum dust collection device 4, the sand box 5, and the blower 6 are all located in the equipment cavity. A through hole is provided on the upper part of the partition plate 16, and the connecting cable is connected to the operation panel 2, the power supply 3, the vacuum dust collection device 4, and the blower 6 through the through hole, thereby reducing the impact of sand and dust in the equipment cavity on the operation of electrical components when entering the electrical control cavity.

[0030] The cross-section of the sand box 5 gradually decreases from top to bottom, so that the sand in the sand box 5 can be completely discharged from the sand delivery pipe 8 at the bottom.

[0031] This utility model realizes the transformation of sand-addition operations on EMUs from manual to automated, and integrates functions such as automatic sand addition, sealing and dust prevention, and real-time monitoring. It reduces manual intervention, greatly saves maintenance personnel and time costs, and improves work efficiency. At the same time, through the sealing and dust prevention design and the application of vacuum dust collection device 4, it significantly reduces dust overflow, greatly improves the working environment of front-line EMU maintenance personnel, and reduces the impact of on-site dust on the health of workers.
