Description

Technical Field

[0001] This application relates to the field of track technology, and specifically, to a snow protection device for a bogie and a rail vehicle. Background Art

[0002] The unique low temperature, heavy snow and strong wind in alpine regions bring a series of special problems to rail transit operations. In winter, due to heavy snowfall or the surrounding area of the line being covered with heavy snow, when a rail vehicle runs at high speed, it will cause relatively strong train wind around it. The strong shear flow between the bottom of the train and the ground and the disturbance of the bogie will stir up the snow on the line. After being disturbed, the snowflakes flow through the bogie area. Some snowflakes deposit on the bogie because the moving speed inside the bogie decreases, and some snowflakes collide with the bogie structure during high-speed movement and adhere to the bogie.

[0003] For traditional snow protection devices of rail vehicles, due to insufficient snow protection ability, they cannot work under cold conditions due to low temperature.

[0004] Therefore, the traditional snow protection device of rail vehicles cannot carry out snow protection work due to its insufficient snow protection ability, which is a technical problem that needs to be urgently solved by those skilled in the art.

[0005] The above information disclosed in the background art is only used to enhance the understanding of the background of this application, so it may contain information on prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0008] Two heating boxes, the actual temperature inside the heating boxes can be maintained within a preset range, and are used to be fixed on an external fixed surface;

[0009] A snow protection board, including a snow protection board body and a rotating shaft fixed on one side of the snow protection board body, and both ends of the rotating shaft protrude from the snow protection board body;

[0010] A pair of mounting seats, one pair of mounting seats corresponding to one snow protection board, and the pair of mounting seats are respectively fixed in the two heating boxes; both ends of the rotating shaft are respectively rotatably connected to the two mounting seats, and the snow protection board body is located between the two heating boxes;

[0011] A driving device, located in one of the heating boxes, and fixedly connected to one end of the rotating shaft;

[0012] Wherein, the driving device is used to drive the rotating shaft to rotate reciprocally so that the snow shield can swing reciprocally with the rotating shaft as the axis.

[0013] According to the second aspect of the embodiments of the present application, there is provided a rail vehicle, including:

[0014] The above snow protection device, wherein the two heating boxes are respectively fixed on the lower bottom surfaces of the two side beams of the bogie frame, and the two snow shields are respectively located outside the two wheel sets of the rail vehicle bogie and are parallel to the axles of the wheel sets.

[0015] Due to the adoption of the above technical solutions in the embodiments of the present application, the following technical effects are achieved:

[0016] The train wind generated during the operation of the rail vehicle, the strong shear flow between the bottom of the train and the ground, and the disturbance of the bogie are interfered by the reciprocating swing of the snow shield with the rotating shaft as the axis, reducing the height of the air flow, weakening the intensity of the air flow, reducing the speed of the snowflakes, and flowing in a direction opposite to the running direction of the rail vehicle close to the track and away from the bogie, greatly reducing the probability of snowflakes colliding with and adhering to the bogie.

[0024] In order to make the technical solutions and advantages in the embodiments of the present application clearer and more understandable, the exemplary embodiments of the present application will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown, the snow protection device of the bogie in the embodiment of the present application includes:

[0027] Two heating boxes, the actual temperature inside the heating box can be maintained within a preset range and is used to be fixed on an external fixed surface; the bottom of the heating box is represented by 13, Figure 1 The heating box cover is omitted in the figure;

[0028] A snow protection board, including a snow protection board body 11 and a rotating shaft 12 fixed to one side of the snow protection board body, and both ends of the rotating shaft protrude from the snow protection board body;

[0029] A pair of mounting seats 2, one pair of mounting seats corresponding to one snow protection board, and the pair of mounting seats 2 are respectively fixed in the two heating boxes; both ends of the rotating shaft 12 are respectively rotatably connected to the two mounting seats 2, and the snow protection board body 11 is located between the two heating boxes;

[0030] A driving device 3, which is located in one of the heating boxes and is fixedly connected to one end of the rotating shaft 12;

[0031] Wherein, the driving device 3 is used to drive the rotating shaft 12 to rotate reciprocally so that the snow protection board can swing reciprocally with the rotating shaft 12 as the axis.

[0032] The snow protection device of the bogie according to the embodiment of the present application is used to protect the bogie of the rail vehicle from snow, preventing the snowflakes from being disturbed by the train wind generated during the operation of the rail vehicle and flowing towards the bogie area. The snow protection device according to the embodiment of the present application itself has two heating boxes; the driving device, the mounting seat, and the part where the rotating shaft of the snow protection plate is rotatably connected to the mounting seat are all located inside the heating boxes. In this way, only the snow protection plate body of the snow protection plate and the middle part of the rotating shaft are exposed outside. The actual temperature inside the heating box can be maintained within a preset range, so that the actual temperature of the environment where the driving device, the mounting seat, the rotating shaft, and the part where the rotating shaft is rotatably connected to the mounting seat is within the preset range, that is, the temperature inside the heating box is controllable. In this way, the snow protection device has the ability to maintain temperature and has a strong ability to prevent low temperature, enabling the snow protection device to adapt to the external low temperature and work normally. The snow protection method of the snow protection device is that both ends of the rotating shaft of the snow protection plate are rotatably connected to the mounting seat, and the driving device is fixedly connected to one end of the rotating shaft. In this way, when the driving device drives the rotating shaft to rotate reciprocally, it will drive the snow protection plate to swing reciprocally around the rotating shaft. The train wind generated during the operation of the rail vehicle, the strong shear flow between the bottom of the train and the ground, and the disturbance of the bogie are interfered by the snow protection plate swinging reciprocally around the rotating shaft, reducing the height of the air flow, weakening the intensity of the air flow, reducing the speed of the snowflakes, and making the snowflakes flow in the direction opposite to the running direction of the rail vehicle close to the track and away from the bogie, greatly reducing the probability of the snowflakes colliding with and adhering to the bogie.

[0033] Specifically, the external fixed surface can be the lower bottom surface of the side beam of the bogie frame or the lower bottom surface of the car body.

[0034] Specifically, the paired mounting seats are respectively fixed at the inner top of the two heating boxes.

[0035] During implementation, the value range of the angle of the forward and backward swing of the snow protection plate during reciprocating swing is greater than or equal to 5 degrees and less than or equal to 15 degrees.

[0036] The size of the angle of the forward and backward swing of the snow protection plate during reciprocating swing and the swing frequency determine the interference force of the snow protection device, and thus determine the snow protection effect of the snow protection device.

[0037] During implementation, a heating coating is coated on the outer surface of the snow protection plate.

[0038] In this way, by coating a heating coating on the outer surface of the snow protection plate, the snowflakes adhering to the snow protection plate can be melted, preventing the snowflakes from gradually accumulating and causing the snow protection plate to not rotate.

[0039] During implementation, a heating wire is embedded in the snow protection plate, and the heating wire is used to heat the entire snow protection plate.

[0040] In this way, by embedding a heating wire in the snow guard, the snowflakes adhering to the snow guard can be melted, preventing the snowflakes from gradually accumulating and causing the snow guard to stop rotating.

[0041] During implementation, the heating box includes:

[0042] A box body;

[0043] A temperature sensor for obtaining the actual temperature inside the box body;

[0044] A heating element disposed inside the box body; the heating element is connected to the heating wire;

[0045] A control unit communicatively connected to the temperature sensor and the heating element respectively;

[0046] Wherein, the control unit is configured to control the operation of the heating element according to the actual temperature inside the box body obtained by the temperature sensor, so that the temperature inside the box body is maintained within a preset range.

[0047] In this way, the heating box can dynamically control the working state of the heating element according to the actual temperature inside the box body, such as running at high gear, running at low gear, etc., so that the temperature inside the box body is maintained within a preset range.

[0048] Specifically, the lower bottom of the box body is a lower box cover that can be opened.

[0049] In this way, when it is necessary to inspect and repair the components inside the heating box, only the lower box cover needs to be opened to perform the inspection and repair.

[0050] During implementation, as Figure 1 and Figure 2 shown, there are two snow guards, and there are two pairs of mounting seats 2;

[0051] As Figure 1 and Figure 2 shown, the snow protection device further includes:

[0052] Two racks 41, one rack 41 is installed at the inner top of one heating box;

[0053] Four gears 42, a part of the rotating shaft 12 located between the snow guard body 11 and the mounting seat 2 is sleeved with a gear 42, and the two gears 42 located in the same heating box are meshed with the rack 41;

[0054] Wherein, the driving device 3 drives the connected rotating shaft 12 to reciprocate, and drives the other rotating shaft 12 to reciprocate synchronously through the transmission of the gear 42 and the rack 41, so that the two snow guards swing synchronously and reciprocally.

[0055] The setting of two snow guards results in a relatively large interference force during reciprocating swing. The two racks and four gears are all located inside the heating box, ensuring the normal operation of the transmission between the gears and the racks without being affected by the external low temperature, snow, and wind.

[0056] During implementation, as Figure 1 and Figure 2 shown, the snow protection device further includes:

[0057] A coupling 5, located in the same heating box as the driving device 3, and the coupling 5 fixedly connects the output shaft of the driving device in the same heating box and one end of the rotating shaft;

[0058] Wherein, the driving device 3 is used to drive the rotating shaft 12 to reciprocate through the coupling 5.

[0059] The fixation of the output shaft of the driving device and the rotating shaft is realized through the coupling, and the connection method is simple and the fixation is reliable.

[0060] During implementation, as Figure 1 and Figure 2 shown, the mounting seat 2 includes:

[0061] A mounting seat body, which has a through mounting seat body through-hole;

[0062] A bearing, the outer ring of the bearing is fixed to the inner wall of the mounting seat body through-hole, and the inner ring of the bearing is fixed to one end of the rotating shaft.

[0063] Through the bearing and the mounting seat body through-hole, the rotational connection between the rotating shaft and the mounting seat is conveniently realized.

[0064] Specifically, the driving device includes a cylinder, and the gas from an external air source is connected to the cylinder through a three-position four-way valve.

[0068] In this way, no matter which direction the rail vehicle travels in, there is a snow guard located in front of the bogie in the forward direction, swinging back and forth to interfere, reducing the height of the air flow, weakening the intensity of the air flow, reducing the speed of the snowflakes, and making the snowflakes flow in a direction close to the track and away from the bogie and opposite to the running direction of the rail vehicle, greatly reducing the probability of the snowflakes colliding with and adhering to the bogie.
