[0018] Figure 5 This is a schematic diagram of the second structure of the air knife of this utility model. Detailed Implementation

[0019] like Figures 1-3 The figures show different structural schematic diagrams of the railway track snowplow provided by this utility model. As can be seen from the figures, the railway track snowplow of this utility model includes: a car body 4 that can travel along the railway track; a handle 2 installed on one side of the car body for easy pushing by the user; a fan 8 installed on the car body for outputting gas; a pair of air blades 6 connected to the fan through a pipeline for blowing away snowfall on the railway track with gas; a power supply box 3 installed on the car body for providing power to the fan; and a control panel 1 installed on the handle and electrically connected to the power supply box and the fan respectively.

[0020] Specifically, the vehicle body of this utility model can travel along railway tracks. Two pairs of rollers 5 are installed at the front and rear of its bottom. Each pair of rollers includes two rollers located on either side of the front or rear of the bottom of the vehicle body, and the two rollers are connected together by a pivot. The rollers adopt the structure of existing train wheels, and the distance between a pair of rollers is equal to the distance between the railway tracks. In the design, the vehicle body can be a closed structure, that is, a cuboid structure composed of a frame and six side plates. Depending on the needs, corresponding holes can be opened on the side plates, such as holes on the front side plate for the air blades to be exposed. Alternatively, the vehicle body can also be a fully open frame structure, that is, a structure composed of a frame and a base plate.

[0021] The vehicle can move by human push, and a handle is installed on one side of the vehicle to facilitate pushing. The handle can be fixedly connected to one side of the upper part of the vehicle (such as the rear). Figure 1 (As shown). Alternatively, the handle can also be connected to the vehicle body via a rotating connection (as shown). Figure 2 As shown in the figure, the handle can rotate relative to the vehicle body, and after rotation, the handle can be fastened to the vehicle body, reducing the space occupied and making it easier to store and transport.

[0022] Furthermore, to reduce the labor intensity of railway workers, the car body of this utility model can also move automatically under the drive of an electric motor. For example, one pair of rollers in the two pairs of rollers (such as the pair of rollers located at the rear) can move under the drive of an electric motor. Correspondingly, a double-output shaft motor 9 can be installed at the rear of the car body floor (see...). Figure 3 In this dual-output-shaft motor, one pair of extended shafts extend in opposite directions, with the direction of extension aligned with the width direction of the vehicle body (i.e., perpendicular to the vehicle's travel direction). The other pair of rollers (such as the pair located at the front) can move accordingly. Alternatively, the dual-output-shaft motor can transmit power to the shaft of the other pair of rollers via a transmission mechanism such as a belt drive or gear drive, allowing both pairs of rollers to rotate simultaneously. The structure where the motor drives the rollers can refer to existing technologies.

[0023] To power the motor on the vehicle body, this invention installs a power supply box on the vehicle body's floor and connects it to the motor via wires. The battery in the power supply box can be a rechargeable battery, and corresponding charging interfaces (not shown in the figure) are provided on the vehicle body.

[0024] To remove snow from the tracks as the vehicle travels along them, this invention includes a fan installed on the vehicle's underbody. This fan is a high-pressure fan capable of outputting high-pressure airflow and has two or two pairs of air outlets. Each air outlet or pair of air outlets is connected to an air inlet 61 of an air knife (see reference). Figure 4 , Figure 5(The diagram only shows the air knife with one air inlet) which is connected to the air duct, so that the air knife can blow away the snow under the action of the high-pressure air output by the fan.

[0025] To secure the air blades, a pair of mounting seats 7 are installed at the front of the vehicle's floor, and a pair of air blades are respectively mounted on the pair of mounting seats. To allow the air blades to rotate relative to the vehicle body to change the direction of the high-pressure airflow and improve the snow removal effect, each air blade of this invention is rotatably connected to its corresponding mounting seat.

[0026] Among them, the air knife can be adopted as follows: Figure 4 The structure shown has a pair of rotating shafts 63 extending from both sides of the air knife housing 62, which are rotatably connected to the fixed base. Correspondingly, the fixed base corresponding to the air knife includes a pair of seat bodies (not shown in the figure) located at the front of the vehicle body floor and on both sides of the corresponding air knife, and the pair of seat bodies are rotatably connected to the rotating shafts on both sides of the corresponding air knife. In the design, the air inlet 61 on the air knife housing is located on the rear side of the air knife (i.e., the side opposite to the air outlet of the air knife).

[0027] Alternatively, the air blade can also be used as follows: Figure 5 The structure shown features a pair of lugs 64 on the rear side of the air knife housing 62, which are rotatably connected to the fixed seat via a pivot passing through the lugs. Correspondingly, the fixed seat for the air knife includes a U-shaped base located on the rear side of the corresponding air knife. The base can be inserted between the lugs or located outside the lugs. The base has through holes or countersunk holes corresponding to the positions of the lugs. The pivot connects the base to the lugs, allowing the air knife to rotate relative to the fixed seat. The hinged structure of the U-shaped base and the lugs can be found in existing technology and will not be described in detail here.

[0028] During assembly, a pair of air blades are installed at an angle relative to the vehicle body, with their air outlets extending onto the body. The corresponding mounting brackets ensure the air blades are installed vertically, and the assembled air blades are staggered vertically, meaning they are at different heights relative to the vehicle body floor. This vertical and vertical arrangement of the air blades allows them to blow away snowfall from both sides of the track, improving snow removal efficiency.

[0029] During the design process, the high-pressure blower and air knife both adopted existing technologies that can provide high-pressure air blowers and their matching air knife structures, and their structures are described in detail here.

[0030] Furthermore, to adjust the walking speed of the snowplow driven by the motor and the snow-blowing force of the fan, a control panel is installed at a suitable position on the handle, such as near the upper part of the handlebars, and is electrically connected to the power box, motor, and fan via wires. Further, the motor and fan can be connected to a frequency converter. The output of the frequency converter is connected to the motor and fan, and the input is connected to the control panel. The control panel controls the frequency converter to indirectly control the motor and fan; that is, the frequency converter controls the motor speed and fan speed to adjust the vehicle's walking speed and fan force respectively. In the design, a multi-speed adjustment method can be adopted. Different walking speed and fan force level buttons or knobs (not shown in the figure) are set on the control panel. By switching different levels, different motor speeds and different fan forces are achieved. Controlling the motor and fan via the control panel is readily apparent to those skilled in the art and will not be described in detail here.

[0031] In summary, this utility model of a railway track snow removal vehicle has a simple structure and is easy to manufacture and use. It can be manually pushed or driven by an electric motor to move automatically as needed. It can remove snow from the railway track through a pair of air blades, which can remove a large amount of snow on the railway track in a short time, significantly improve snow removal efficiency, greatly reduce the labor intensity of railway workers, and ensure the safety of workers. Timely removal of snow on the tracks can ensure the normal operation of trains and improve the safety and reliability of railway transportation.

[0032] Although the present invention has been described in detail above, it is not limited thereto. Those skilled in the art can make modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood as falling within the protection scope of the present invention.
