Description

Technical Field

[0001] This utility model relates to the field of railway sand removal technology, specifically a sand removal guiding device for railway sand removal. Background Technology

[0002] In my country, many railways are built in areas prone to sandstorms. During the spring and autumn seasons, strong winds can blow sand from the surrounding areas onto the railway track bed. This can range from affecting train speed and increasing wear between train wheels and rails to burying the track bed and rails, disrupting normal train operations. Therefore, sand removal and guiding devices are needed to remove the sand from the rails.

[0003] According to the utility model patent application CN219547672U, a railway sand-removing device is disclosed, comprising a base plate, columns, and a horizontal plate. A battery box is mounted on the top of the base plate via a mounting bracket, and an air pump is mounted on the top of the battery box via the mounting bracket. Columns are fitted onto the top of both sides of the base plate, and a shelf is connected to the bottom of each column via a threaded groove. A cleaning brush for wiping the track is bolted to the bottom of each shelf. A horizontal plate is welded to both ends of one side of the base plate, and an air pipe is threaded through both ends of the top of the horizontal plate. A nozzle is connected to the bottom of each air pipe via a threaded groove. A dust cover is connected to the air inlet of the air pump via a threaded groove, and a three-way valve is connected to the air outlet of the air pump via a threaded groove. The top of the three-way valve has... A hose is connected via a pipe joint, with one end of the hose fixed to the top of the air pipe. Although this device can draw air from outside the dust cover into its interior via an air pump, and then deliver it into the air pipe through a three-way valve and hose, before blowing it out through a nozzle at the bottom of the air pipe, the strong airflow blows the debris and sand swept off the rails away. However, when guiding sand removal on the railway, the device blows sand off the rails through the nozzle, but the blown sand scatters everywhere and can easily fly back onto the rails, resulting in poor sand removal efficiency and an inability to quickly remove accumulated sand piles, thus reducing its practicality. Therefore, we provide a sand removal guiding device for railway sand removal to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a sand-draining guide device for railway sand drainage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sand-draining guiding device for railway sand drainage, comprising a sand-draining car, wherein the sand-draining car is internally equipped with a sand-draining and outgoing mechanism, the sand-draining and outgoing mechanism comprising two first conveyor belts, the outer surface of each first conveyor belt being rotatably connected to the inner wall of the sand-draining car, and guide blocks arranged at equal intervals being fixedly installed on the outer surface of each first conveyor belt; two first drive rollers are rotatably connected to the inner wall of each first conveyor belt, the top and bottom ends of each first drive roller being rotatably connected to the inner top and inner bottom walls of the sand-draining car; and a first stepper motor is provided above each sand-draining car.

The output end of the third stepper motor is through the sand-discharging car and fixedly connected to the right end of one of the second transmission rollers.

[0006] Furthermore, two support rods are fixedly installed on the upper surface of the sand-discharging vehicle, and a connecting block is fixedly installed on the right side of each support rod.

[0007] Furthermore, a first protective box is fixedly installed on the right side of the first stepper motor, and the bottom surface of the first protective box is fixedly connected to the upper surface of the sand removal vehicle.

[0008] Furthermore, a second protective box is fixedly installed on the bottom surface of the second stepper motor, and the back of the second protective box is fixedly connected to the front of the sand removal vehicle.

[0013] Compared with existing technologies, this sand-draining guide device for railway sand drainage has the following advantages:

[0014] This invention features a first stepper motor that powers a first transmission roller, which in turn drives a first conveyor belt. The rotation of the first conveyor belt, in turn, drives a guide block, which in turn transports sand from both sides of the rail to one side, thus facilitating the removal of sand from the rail to a distant location.

[0015] This invention utilizes a second stepper motor to power a rotating frame, which then transports sand from the rails to a second conveyor belt. The second conveyor belt then directly transports the sand to a third conveyor belt. A third stepper motor powers a second drive roller, which in turn drives the third conveyor belt to deflect the sand to one side. By controlling the forward and reverse rotation of the third stepper motor, the direction of sand deflection can be selected based on wind direction, preventing sand from flying back onto the railway. This results in a strong sand removal effect and allows for rapid discharge of accumulated sand, making it highly practical. Attached Figure Description

When sand removal from the railway is required, the connecting block 212 facilitates connection between the sand removal vehicle 1 and the external power mechanism. The roller 215 rotates on the rail, allowing the external power mechanism to move the device. The power provided by the first stepper motor 202 drives the first transmission roller 204 to rotate, which in turn drives the first conveyor belt 201 to rotate. The rotation of the first conveyor belt 201 drives the guide block 203 to rotate, allowing the guide block 203 to transport the sand on both sides of the rail to one side, thus facilitating the removal of the sand from the rail to a distant location. The power provided by the second stepper motor 205 drives the rotating frame 206 to rotate. The rotating frame 206 can transport sand from the rails to the second conveyor belt 207. The fourth stepper motor 218 drives the third transmission roller 217 to rotate, which in turn drives the second conveyor belt 207 to directly transport the sand to the third conveyor belt 208. The power provided by the third stepper motor 210 drives the second transmission roller 209 to rotate, which in turn drives the third conveyor belt 208 to discharge the sand to one side. By controlling the forward and reverse rotation of the third stepper motor 210, the direction of the sand discharge can be selected according to the wind direction, thus preventing the sand from flying back onto the railway. This results in a strong sand discharge effect and allows for the rapid discharge of accumulated sand piles. The sweeping plate 216 can sweep away the sand remaining on the rail surface, making the sand discharge guiding device for railway sand discharge more practical.
