[0002] Railway tracks consist of roadbed, ballast, ballast, sleepers, and rails from bottom to top. They are generally higher than the ground. In desert areas, after a railway is built, the wind and sand will slow down or form vortices near the railway due to the obstruction of the railway embankment, which will affect the operation. Therefore, it is necessary to use sand removal devices to remove the sand accumulated on the railway tracks.
[0003] According to the utility model patent application CN218597059U, a sand removal device for a sand removal vehicle is disclosed, including a supporting traveling frame, an excavation and conveying unit, a sand throwing unit, and a collection and conveying device. The excavation and conveying unit and the sand throwing unit are both mounted on the supporting traveling frame. Although this equipment realizes automated and mechanized rail sand removal operations, improves sand removal efficiency, and reduces labor intensity, it lacks protective capabilities during the sand throwing process. Sand is easily blown back onto the track surface by the wind, thus reducing the effectiveness of sand removal. Moreover, it cannot maintain the track in a timely manner after sand removal, failing to reduce the damage caused by sand to the track and reducing the effectiveness of the railway track sand removal device. Therefore, we provide a multifunctional railway track sand removal device to solve the above problems. Utility Model Content

[0013] Compared with existing technologies, this multifunctional railway track sand removal device has the following advantages:
[0014] 1. This utility model, by comprising a protective pipe, a sand-absorbing fan, an auxiliary shell, an auxiliary block, a reciprocating screw, a servo motor, a moving block, and a scraper, can extract sand from the track surface through the cooperation of the sand-absorbing fan and the auxiliary shell, and transfer the sand into the protective pipe. At the same time, the servo motor drives the reciprocating screw to rotate, which in turn causes the moving block to drive the scraper to move back and forth. The scraper can push the sand to move at the same time, thereby discharging the sand from the protective pipe, thus achieving the protective capability. The protective pipe and the scraper work together to reduce the amplitude of sand discharge, preventing sand from being blown back onto the track surface by the wind, and effectively improving the sand removal effect.

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0022] This embodiment provides a multifunctional railway track sand removal device. The device is used to clean sand covering the railway surface. The sand under the outer shell 1 is drawn into the protective pipe 201 by the sand suction fan 202. Then, the reciprocating screw 205 is rotated by the servo motor 206, which in turn causes the moving block 207 to move the scraper 208, thereby cleaning the sand in the protective pipe 201. This device can protect the track during sand removal and avoid secondary pollution caused by excessive sand blowing. The device also uses the solenoid valve 304 to allow the maintenance oil in the oil storage tank 301 to flow into the oil supply box 305 through the three-way pipe 303. The oil leakage hole and 307 continuously moisten the sponge roller 306, so that the sponge roller 306 can evenly apply the maintenance oil to the railway track surface when it rotates. This device can perform maintenance after sand removal and effectively reduce the aging rate of the railway track.
[0023] Reference Figure 1 and Figure 2 A multifunctional railway track sand removal device includes a housing 1, a sand removal mechanism 2 inside the housing 1, and a maintenance mechanism 3 on the front of the housing 1. The sand removal mechanism 2 includes a protective pipe 201, which is fixedly connected to the inner wall of the housing 1. A connecting ring 209 is fixedly connected to the back of the housing 1, and a traction hook 210 is rotatably connected inside the connecting ring 209. Through the cooperation of the connecting ring 209 and the traction hook 210, a good traction position can be provided for the housing 1, improving the ease of traction of the housing 1 by external equipment and increasing the convenience of the device.
[0024] Reference Figure 2 A sand-absorbing fan 202 is fixedly connected to the upper surface of the outer shell 1, and an auxiliary shell 203 is fixedly connected to the inner wall of the outer shell 1. The sand-absorbing end of the sand-absorbing fan 202 passes through the outer shell 1 and is fixedly connected to the upper surface of the auxiliary shell 203. Two sets of connecting blocks 211 are fixedly connected to the bottom surface of the outer shell 1. Each set of connecting blocks 211 has a rotatable wheel 212 inside. By using the cooperation of the connecting blocks 211 and the wheels 212, the device can be moved easily, and it can also be quickly changed direction during the movement, which increases the convenience of the device.
[0025] Reference Figure 2 and Figure 3The sand outlet of the sand suction fan 202 passes through the protective pipe 201 and extends into the interior of the protective pipe 201. An auxiliary block 204 is fixedly connected to the inner wall of the protective pipe 201. A reciprocating screw 205 is rotatably connected inside the auxiliary block 204. A servo motor 206 is fixedly connected to the left end of the reciprocating screw 205. An auxiliary bearing 213 is sleeved on the outer surface of the reciprocating screw 205 and is embedded in the interior of the auxiliary block 204. The auxiliary bearing 213 can reduce the friction generated by the reciprocating screw 205 when rotating, making the reciprocating screw 205 more sensitive when rotating. It can also reduce the wear rate of the reciprocating screw 205 and increase the durability of the reciprocating screw 205.
[0026] Reference Figure 3 The reciprocating lead screw 205 has a threaded connection to a moving block 207 on its outer surface. The moving block 207 is slidably connected to the inside of the auxiliary block 204. The outer surface of the servo motor 206 is provided with a protective shell 214. The right side of the protective shell 214 is fixedly connected to the left side of the auxiliary block 204. The protective shell 214 can protect the servo motor 206, prevent the servo motor 206 from being affected by external interference during operation, and also increase the dustproof capability of the servo motor 206 and improve the service life of the servo motor 206.
[0027] Reference Figure 3 A scraper 208 is fixedly connected to the front of the moving block 207, and a sliding block 215 is fixedly connected to the front of the scraper 208. The sliding block 215 is slidably connected to the inside of the auxiliary block 204. The sliding block 215 can move simultaneously with the scraper 208 and use the friction force generated by itself on the scraper 208 during the movement to improve the stability of the scraper 208 when it moves, thereby increasing the stability of the device.
[0028] Reference Figure 1 and Figure 4 The maintenance mechanism 3 includes an oil reservoir 301, which is fixedly connected to the inner wall of the outer shell 1. A one-way valve 302 is fixedly connected to the upper surface of the oil reservoir 301, a three-way pipe 303 is fixedly connected to the bottom surface of the oil reservoir 301, a solenoid valve 304 is fixedly connected to the outer surface of the three-way pipe 303, and a drain pipe 308 is fixedly connected to the front of the oil reservoir 301. A switch valve 309 is fixedly connected to the outer surface of the drain pipe 308. The drain pipe 308 can improve the convenience of draining the maintenance fluid in the oil reservoir 301, and the switch valve 309 can control the closing state of the drain pipe 308, increasing the convenience of use.
[0029] Reference Figure 4The two ends of the three-way pipe 303 away from the oil storage tank 301 are fixedly connected to the oil supply box 305. Each oil supply box 305 has a sponge roller 306 rotatably connected inside. Each oil supply box 305 has an oil leakage hole 307 on its inner wall. Two reinforcing rings 310 are fixedly connected to the outer surface of the three-way pipe 303. The bottom end of each reinforcing ring 310 is fixedly connected to the upper surface of the oil supply box 305. The reinforcing rings 310 can increase the fixed connection area between the three-way pipe 303 and the oil supply box 305, thereby making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the robustness of the device.
[0030] Working Principle: In use, the sand suction fan 202, servo motor 206, and solenoid valve 304 are first powered on. The outer casing 1 is connected to the external traction equipment via the connecting ring 209 and the traction hook 210. When the device is needed, the sand suction fan 202 and servo motor 206 are started. The suction force generated by the sand suction fan 202 and auxiliary casing 203 is used to extract sand from below the outer casing 1 and transfer it into the protective pipe 201. The servo motor 206 then drives the reciprocating screw 205 to rotate. The auxiliary bearing 213 improves the sensitivity of the reciprocating screw 205 during rotation, causing the moving block 207 to drive the scraper 208 to move repeatedly within the protective pipe 201. The sliding block 215 increases the stability of the scraper 208 during movement. Simultaneously, the scraper 208... During the process, the sand inside the protective pipe 201 can be pushed out continuously, thereby achieving the sand removal capability. In addition, it can effectively protect against excessive sand blowing, preventing the sand from following the wind direction and covering the track again. This effectively improves the sand removal effect. Furthermore, during the movement of the outer shell 1, the sponge roller 306 will rotate continuously due to friction with the track. At this time, the solenoid valve 304 is opened, allowing the pre-added maintenance fluid in the oil storage tank 301 to flow through the three-way pipe 303 to the oil supply box 305. The oil leakage hole 307 continuously moistens the sponge roller 306, thereby evenly applying the maintenance fluid to the surface of the railway track through the sponge roller 306 and maintaining it. This effectively reduces the damage caused by sand to the track and slows down the aging rate of the railway track.
