Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a snow removal device, a rail vehicle and a rail transit system. Background Art

[0002] Rail vehicles run on track beams. In cold areas or snowy weather, snow is likely to accumulate on the track beams, which will affect the normal running of rail vehicles and bring safety hazards to the operation of rail vehicles.

[0003] In the prior art, the snow removal device used for rail vehicles is usually a push-type snowplow. When the snow accumulates to a certain height, the resistance of the snow is relatively large, and the brush of the snowplow is squeezed and bent, resulting in reduced snow removal efficiency and poor snow removal effect. Utility Model Content

[0004] In order to solve the above problems, the present application provides a snow removal device, which optimizes the structure of the snow removal device in a targeted manner, uses a roller brush instead of a flat brush, and improves the prior art's flat-push snow removal to a rotary snow sweeping device, so as to provide a greater snow sweeping force and snow sweeping speed, thereby effectively improving the snow sweeping efficiency of the snow removal device and improving the snow sweeping effect. In addition, the present application also provides a rail vehicle and a rail transit system equipped with the snow removal device, which specifically include the following solutions:

[0005] In a first aspect, the present application provides a snow removal device for a rail vehicle, comprising:

[0006] A fixing bracket, suitable for connection with a rail vehicle;

[0007] A roller brush is rotatably connected to a fixed bracket;

[0008] A driving wheel is rotatably connected to the fixed bracket and is drivingly connected to the roller brush, and the driving wheel is suitable for contacting the beam surface of the track;

[0009] The roller brush is located at the front end of the driving wheel along the traveling direction of the rail vehicle. When the rail vehicle travels, the driving wheel is driven to rotate on the beam surface of the rail, and the driving wheel drives the roller brush to rotate to sweep away the snow on the beam surface of the rail.

[0010] The snow removal device of the present application is provided with a fixed bracket for fitting and mounting with a rail vehicle to support and connect a roller brush. By providing a rotational connection between the roller brush and the fixed bracket, it can be ensured that the roller brush and the fixed bracket can be connected and fixed to each other, and can also rotate relative to each other to ensure the normal operation of the roller brush. The snow on the beam surface of the track can be lifted and thrown out by the high-speed rotation of the roller brush. Compared with the flat push snow sweeping of the prior art, the rotary snow sweeping can provide a greater snow sweeping force, which can effectively improve the snow sweeping efficiency and enhance the snow sweeping effect. Further, the present application also drives the roller brush to rotate by arranging a driving wheel at the rear end of the roller brush. The driving wheel contacts the beam surface of the track, and the traction force of the rail vehicle itself and the friction force between the driving wheel and the beam surface of the track are used as the power source of the roller brush, so as to ensure that the driving roller brush rotates to remove snow and save energy. In addition, the driving wheel can also play a role of shock absorption, ensuring that the roller is always close to the beam surface of the track, thereby further improving the snow sweeping effect of the roller brush.

[0011] In one embodiment, the snow removal device includes a commutator, which is transmission-connected between the driving shaft of the driving wheel and the rotating shaft of the roller brush so that the rotating direction of the roller brush is opposite to the rotating direction of the driving wheel.

[0012] In this embodiment, a commutator is provided between the driving shaft of the driving wheel and the rotating shaft of the roller brush to adjust the rolling direction of the roller brush relative to the wheel of the rail vehicle, so that the roller brush rotates in the opposite direction of the forward movement of the rail vehicle, thereby ensuring that the roller brush can throw the snow on the beam surface of the track forward and avoid the snow interfering with the normal operation of the rail vehicle.

[0013] In one embodiment, the commutator includes a driving wheel, a driven wheel and a transmission mechanism, the driving wheel is coaxially fixed with the driving wheel, the driving wheel and the driven wheel are meshed and connected to the rotating shaft via the transmission mechanism.

[0014] In this embodiment, the driving wheel is coaxially fixed with the driving wheel so that the driving wheel is used as the input end of the commutator. The driving wheel is meshed with the driven wheel, and the driving force of the input end is transmitted to the rotating shaft by the transmission mechanism, so that the rotating shaft can rotate in the opposite direction to the driving shaft of the driving wheel, so as to lift the snow on the beam surface of the track forward. The transmission efficiency and accuracy of this structure are relatively high, and the structure is compact, which is conducive to the miniaturization design of the snow removal device.

[0015] In one embodiment, the commutator includes a driving wheel, a driven wheel and a transmission mechanism, wherein the driving wheel and the driven wheel are coaxially fixed with the driving wheel and the roller brush respectively, and are meshed and transmitted through the transmission mechanism.

[0016] In this embodiment, the driving wheel is coaxially fixed with the driving wheel so that the driving wheel serves as the input end of the commutator, and the driven wheel is coaxially fixed with the roller brush so that the driven wheel serves as the output end of the commutator. The driving wheel and the driven wheel are meshed by setting a transmission mechanism so that the driving force of the driving wheel is transmitted to the roller brush through the transmission mechanism and the driven wheel in sequence, so that the rotating shaft of the roller brush can rotate in the opposite direction to the driving shaft of the driving wheel so as to lift the snow on the beam surface of the track forward. This structure has high transmission efficiency and transmission accuracy, and can ensure that the roller brush has sufficient power to rotate.

[0017] In one embodiment, the transmission mechanism includes a transmission belt.

[0018] In one embodiment, the commutator includes an active rod, a driven rod and a connecting rod, one end of the active rod and the driven rod are respectively coaxially fixed with the driving wheel and the roller brush, and the other end of the active rod and the driven rod are respectively rotatably connected to one end of the connecting rod.

[0019] In this embodiment, the active rod is coaxially fixed with the driving wheel so that the active rod serves as the input end of the commutator, and the driven rod is coaxially fixed with the roller brush so that the driven rod serves as the output end of the commutator. The active rod and the driven rod are rotatably connected by a connecting rod, and the opposite ends of the connecting rod are arranged on both sides of the driving shaft in the vertical direction to form an anti-parallelogram connecting rod mechanism, thereby realizing power transmission from the driving wheel to the roller brush, and making the two rotate in opposite directions. This structure has the advantages of simple design and low noise.

[0020] In one embodiment, the snow removal device includes a shock absorber connected between a drive shaft of a drive wheel and the rail vehicle for maintaining contact between the drive wheel and a beam surface of the rail.

[0021] In this embodiment, a shock absorber is arranged between the driving shaft of the driving wheel and the rail vehicle to prevent the driving wheel from jumping up and down relative to the beam surface of the rail, thereby ensuring that the driving wheel is always close to the beam surface of the rail, thereby maintaining contact between the driving wheel and the beam surface of the rail and generating friction, thereby ensuring that the driving wheel provides sufficient driving force to the roller brush.

[0022] In one embodiment, the track is a monorail, and the axial dimension of the roller brush is greater than the width dimension of the beam surface of the monorail.

[0023] In this embodiment, based on the fact that the track is a monorail, the axial dimension of the roller brush is set to be larger than the width dimension of the beam surface of the monorail to ensure that the roller brush can fully cover the beam surface of the monorail. When the roller brush rotates, most of the snow on the beam surface of the track can be lifted and thrown away to avoid snow accumulation.

[0024] In one embodiment, the track is a double track, and the axial dimension of the roller brush is greater than the maximum width dimension of the double track.

[0025] In this embodiment, based on the double track, the axial dimension of the roller brush is set to be larger than the maximum width dimension of the double track to ensure that one roller brush can cover the two beam surfaces of the double track. When the roller brush rotates, the snow on the two beam surfaces of the double track can be lifted and thrown away, and at the same time, the components in the snow removal device of this application can be simplified.

[0026] In one embodiment, the track is a double track, the number of the driving wheels is two, each driving wheel is in contact with a beam surface of one track and is drivingly connected to one end of the roller brush.

[0027] In this embodiment, based on the double track, two driving wheels are arranged to contact the two beam surfaces of the double track, and the roller brush is driven to rotate by the two driving wheels. This can increase the rotation rate of the roller brush and improve the stability of the rotation of the roller brush, thereby improving the snow clearing effect.

[0028] In one embodiment, the fixed bracket includes a support arm and at least two connecting arms, the support arm is connected between the driving shaft of the driving wheel and the rail vehicle, and the at least two connecting arms are arranged on both sides of the roller brush along the axial direction of the roller brush and are respectively connected between the rotating shaft of the roller brush and the support arm.

[0029] In this embodiment, a support arm is provided in the fixed bracket, and the support arm is used to support and connect the driving wheel and the rail vehicle. At the same time, connecting arms are provided on both sides of the roller brush along its own axis, and the connecting arms are used to connect the rotating shaft of the roller brush and the support arm, so that the rotation stability of the roller brush can be improved, and the roller brush can be prevented from tilting and shaking, etc., to ensure that the roller brush can always contact the beam surface of the track.

[0030] In a second aspect, the present application provides a rail vehicle, comprising a vehicle body and a snow removal device as in any of the above embodiments, wherein the snow removal device is fixed to the front end of the vehicle body and is used to remove snow from the beam surface of the track.

[0031] It can be understood that the rail vehicle provided in the second aspect of the present application, because it adopts the snow removal device provided in the first aspect of the present application, also has all possible beneficial effects in any embodiment provided in the first aspect of the present application.

[0032] In one embodiment, the fixing bracket of the snow removal device is fixed to the steering suspension of the rail vehicle.

[0033] In this embodiment, the fixed bracket of the snow removal device is fixed to the steering suspension of the rail vehicle so that when the rail vehicle turns, the roller brush of the snow removal device can follow the steering suspension to ensure that the roller brush of the snow removal device is always in contact with the beam surface of the track to achieve a good snow-clearing effect.

DETAILED DESCRIPTION

[0048] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

[0049] The following descriptions of the embodiments are with reference to the attached diagrams to illustrate specific embodiments that the present application can be used to implement.

[0052] It should be noted that the track of the rail transit system of the present application can be a double track or a single track, and the rail vehicle can be a tram, for example, a cloud bus. The cloud bus can also be called a rubber-wheeled tram, which is a small-capacity rail transit tool that can be used in the fields of super-large urban transportation branches and dense lines, urban comprehensive transportation hub shuttle lines, large and medium-sized city trunk lines, tourist attractions and sightseeing lines. The track of the cloud bus is generally laid on an elevated structure. In cold areas or snowy weather, the snow will cover the beam surface of the track (that is, the walking surface), causing the cloud bus to slip when walking on the track, affecting the safety of operation. The present application can remove the snow on the beam surface of the track by installing a snow removal device at the front end of the rail vehicle to ensure the normal operation of the rail vehicle.

[0053] Please refer to Figures 1 to 4 ,in Figure 1 This is a structural schematic diagram of a snow removal device 100 provided in an embodiment of the present application from a first perspective; Figure 2 This is a structural schematic diagram of a snow removal device 100 provided in an embodiment of the present application from a second perspective; Figure 3 It is a structural schematic diagram of a snow removal device 100 provided in an embodiment of the present application from a third perspective; Figure 4This is a structural schematic diagram of a snow removal device 100 provided in an embodiment of the present application from a fourth perspective.

[0054] like Figures 1 to 4 As shown, in one embodiment, the snow removal device 100 provided by the present application includes a fixed bracket 10, a roller brush 20 and a driving wheel 30. The fixed bracket 10 includes a fixing portion 11 and a supporting portion 12, and the fixing portion 11 is located at the upper end of the supporting portion 12 in the vertical direction. The fixing portion 11 of the fixed bracket 10 can be detachably connected to the body of the rail vehicle, and the supporting portion 12 can be used to support the roller brush 20. The supporting portion 12 includes a support rod 121 and two support seats 122, the support rod 121 extends along the width direction of the track, and the two support seats 122 are respectively arranged at opposite ends of the support rod 121 and are fixedly connected to the rail vehicle. The support rod 121 passes through the two support seats 122 and is rotatably connected to the support seat 122. The driving wheel 30 is rotatably connected to the fixed bracket 10, specifically, the driving shaft 31 of the driving wheel 30 is fixedly connected to the support rod 121, or it can be understood that the support rod 121 is the driving shaft 31 of the driving wheel 30. The tire of the driving wheel 30 contacts the beam surface of the track, and the tire of the driving wheel 30 can rotate relative to the support seat 122. Further, along the traveling direction of the rail vehicle, the roller brush 20 is arranged at the front end of the driving wheel 30. The roller brush 20 includes a rotating shaft 21 and bristles 22. The rotating shaft 21 of the roller brush 20 also extends along the width direction of the track, and the opposite ends of the rotating shaft 21 are respectively rotatably connected to a support seat 122. The bristles 22 are arranged around the outer peripheral surface of the rotating shaft 21 and contact the beam surface of the track. When the vehicle moves forward, the fixed bracket 10 moves with the rail vehicle, and the driving wheel 30 rotates under the combined action of the traction force of the rail vehicle and the friction force between the driving wheel 30 and the beam surface of the track, thereby driving the roller brush 20 to rotate, and the bristles 22 produce motion interference with the beam surface of the track and lift up and throw the snow on the beam surface of the track. Compared with the flat push snow sweeping of the prior art, the rotary snow sweeping can provide greater snow sweeping force, which can effectively improve the snow sweeping efficiency and enhance the snow sweeping effect.

[0055] Furthermore, the snow removal device 100 of the present application is also provided with a driving wheel 30, which is used to rotate under the combined action of the traction of the rail vehicle and the friction between the driving wheel 30 and the beam surface of the rail, so as to drive the roller brush 20 to work. This solution can not only ensure that the roller brush 20 can rotate to sweep the snow, but also save energy. In addition, the driving wheel 30 can also play a role in cushioning, ensuring that the roller is always close to the beam surface of the rail, thereby further improving the snow sweeping effect of the roller brush 20.

[0056] Please see Figure 5 , Figure 5 It is a partial structural schematic diagram of a snow removal device 100 provided in an embodiment of the present application.

[0057] like Figures 1 to 5 As shown, in one embodiment, the snow removal device 100 provided by the present application further includes a commutator 40. The commutator 40 is transmission-connected between the driving shaft 31 of the driving wheel 30 and the rotating shaft 21 of the roller brush 20, and is used to adjust the rotation direction of the rotating shaft 21 of the roller brush 20 relative to the driving shaft 31, so as to transmit the driving force of the driving wheel 30 to the roller brush 20 and make the roller brush 20 rotate in the opposite direction. It can be understood that based on the driving wheel 30 and most of the structures in the chassis of the rail vehicle are arranged at the rear end of the roller brush 20, if the roller brush 20 and the driving wheel 30 have the same rotation direction, when the rail vehicle moves forward, the rotation of the roller brush 20 will lift the snow on the rail beam surface toward the rear, and the lifted snow may interfere with the operation of the driving wheel 30 or other structural parts in the chassis, and the lifted snow will fall back to the rail beam surface due to being blocked, which will reduce the snow removal effect. The present application sets a commutator 40 to change the rotation direction of the roller brush 20, so that when the rail vehicle moves forward, the roller brush 20 can rotate counterclockwise to lift and throw the snow on the beam surface of the track forward, thereby preventing the accumulated snow from interfering with the normal operation of the rail vehicle.

[0058] For details, please refer to Figures 1 to 5 In one embodiment, the commutator 40 of the present application includes a driving wheel 41 and a driven wheel 42. The driving wheel 41 is arranged at one end of the driving wheel 30 along its own axial direction and is coaxially fixed with the driving wheel 30. The driven wheel 42 is located on the side of the driving wheel 30 where the driving wheel 41 is provided, and the driven wheel 42 is rotatably connected to one of the support seats 122. The number of the driven wheels 42 can be two. For the convenience of introduction, the two driven wheels 42 are defined as a first driven wheel 421 and a second driven wheel 422 respectively. The first driven wheel 421 and the second driven wheel 422 are arranged at intervals along the axial direction of the driving shaft 31, and the first driven wheel 421 is coaxially fixed with the second driven wheel 422. The first driven wheel 421 is meshed with the driving wheel 41, and the second driven wheel 422 is transmission-connected to the rotating shaft 21 of the roller brush 20. When the driving wheel 41 rotates clockwise, the first driven wheel 421 is driven to rotate counterclockwise. The second driven wheel 422 rotates counterclockwise along with the first driven wheel 421 and transmits the driving force to the rotating shaft 21 .

[0059] Furthermore, the commutator 40 of the present application further includes a transmission mechanism 43, which is used to connect the driven wheel 42 to the rotating shaft 21. Specifically, the transmission mechanism 43 may include a transmission wheel 431 and a transmission belt 432. The transmission wheel 431 is coaxially fixed with the rotating shaft 21, or it can be understood that the transmission wheel 431 is sleeved on the periphery of the rotating shaft 21 and fixed relative to the rotating shaft 21. Along the length direction of the driving shaft 31, the transmission wheel 431 and the driven wheel 42 are both arranged on the same side of the driving wheel 30. The transmission wheel 431 and the second driven wheel 422 are connected by a transmission belt 432.

[0060] It can be understood that in this embodiment, by reasonably designing the position and connection relationship between the driving wheel 41, the driven wheel 42, the transmission wheel 431 and the transmission belt 432, the driving force of the driving wheel 30 can be transmitted to the rotating shaft 21 via the driving wheel 41, the driven wheel 42, the transmission belt 432 and the transmission wheel 431 in sequence, which not only ensures the reverse rotation between the rotating shaft 21 and the driving wheel 30 to lift the snow on the beam surface of the track to the front, but also the transmission efficiency and accuracy of the structure are relatively high, and the structure is compact, which is conducive to the miniaturization design of the snow removal device 100.

[0061] It should be noted that the structure of the commutator 40 in the above embodiment is only an exemplary introduction and does not represent the specific structure of the commutator 40 in other embodiments of the present application. Or it can be understood that the number, position and connection relationship of the driving wheel 41 and the driven wheel 42 in the above embodiment is only one possible implementation of the present application. The present application can also change the number, position and connection relationship of the driving wheel 41 and the driven wheel 42 according to the actual application scenario to realize the function of the driving wheel 30 driving the roller brush 20 in reverse.

[0062] For example, see Figure 6 , Figure 6 It is a schematic structural diagram of a commutator 40 provided in another embodiment of the present application.

[0063] like Figures 1 to 6As shown, in another embodiment, the commutator 40 provided by the present application includes a driving wheel 41, a driven wheel 42 and a transmission mechanism 43. The specific transmission mechanism 43 includes a transmission belt 432. The driving wheel 41 is arranged at one end of the driving wheel 30 along its own axial direction and is coaxially fixed with the driving wheel 30. The driven wheel 42 is located on the side of the driving wheel 30 where the driving wheel 41 is provided, and the driven wheel 42 is rotatably connected to one of the support seats 122. The number of the driven wheels 42 can be three. For the convenience of introduction, the three driven wheels 42 are defined as the first driven wheel 421, the second driven wheel 422 and the third driven wheel 423. Along the length direction of the track, the third driven wheel 423 is located between the driving wheel 41 and the first driven wheel 421 and / or the second driven wheel 422. That is, the driving wheel 41 is located at the rear end of the third driven wheel 423, and the first driven wheel 421 and the second driven wheel 422 are located at the front end of the third driven wheel 423. The first driven wheel 421 and the second driven wheel 422 are both rotatably connected to the support seat 122, and the third driven wheel 423 is coaxially fixed to the rotating shaft 21. The transmission belt 432 is meshed and connected with the driving wheel 41, the first driven wheel 421, the third driven wheel 423, and the second driven wheel 422 respectively. The transmission belt 432 is connected to the third driven wheel 423 after the first driven wheel 421 and the second driven wheel 422 are reversed. When the driving wheel 41 rotates clockwise, the transmission belt 432 moves and drives the first driven wheel 421 and the second driven wheel 422 to rotate clockwise, and drives the third driven wheel 423 to rotate counterclockwise, and the third driven wheel 423 drives the rotating shaft 21 to rotate counterclockwise.

[0064] It can be understood that the structure in the above embodiment can also realize the function of the driving wheel 30 reversely driving the roller brush 20, and the structure has high transmission efficiency and transmission accuracy, and can ensure that the roller brush 20 has sufficient power to rotate. It should be noted that the driving wheel 41 and the driven wheel 42 in the above embodiment can include at least one of a gear and an idler wheel, and the corresponding transmission belt 432 can also include one of a chain or a belt, and the present application does not specifically limit this.

[0065] Please see Figure 7 , Figure 7 This is a schematic structural diagram of a commutator 40 provided in yet another embodiment of the present application.

[0066] like Figures 1 to 7As shown, in one embodiment, the commutator 40 of the present application includes an active rod 45, a driven rod 46 and a connecting rod 47. The active rod 45 is connected to the driving shaft 31 of the driving wheel 30 and one end of the connecting rod 47, and the driven rod 46 is connected to the rotating shaft 21 of the roller brush 20 and the other end of the connecting rod 47. One end of the active rod 45 is fixedly connected to the driving shaft 31, and the other end is hinged to the connecting rod 47. One end of the driven rod 46 is fixedly connected to the rotating shaft 21, and the other end is hinged to the connecting rod 47. In the vertical direction, the opposite ends of the connecting rod 47 are arranged on both sides of the driving shaft 31. The active rod 45, the driven rod 46 and the connecting rod 47 cooperate with each other to form an anti-parallelogram linkage mechanism. When the active rod 45 rotates with the driving shaft 31 of the driving wheel 30, the active rod 45 pulls the connecting rod 47 to swing relatively, and the connecting rod 47 drives the driven rod 46 to rotate, thereby driving the roller brush 20 to rotate in the opposite direction.

[0067] It can be understood that in this embodiment, an anti-parallelogram linkage mechanism is formed by using the active rod 45, the driven rod 46 and the connecting rod 47 to achieve the transmission of driving force between the driving wheel 30 and the roller brush 20, and enable the roller brush 20 to rotate in the opposite direction relative to the beam surface of the track. The linkage structure is not only simple in design, but also has the advantages of low noise and light weight.

[0068] It should be noted that the number and position of the commutators 40 in the above embodiment are only used as an exemplary introduction, that is, the number and position of the commutators 40 can be adaptively adjusted according to the actual application scenario, and the present application does not impose any special limitation on this.

[0069] Please look back Figures 1 to 5 In one embodiment, the snow removal device 100 of the present application includes a shock absorber 50, which is connected between the drive shaft 31 of the drive wheel 30 and the rail vehicle, and is used to maintain the contact between the drive wheel 30 and the beam surface of the rail and generate friction between the two. Specifically, the shock absorber 50 includes a cylinder 51, a piston 52 and a spring 53. The cylinder 51 is fixed to the support rod 121 of the fixed bracket 10, that is, fixed to the drive shaft 31 of the drive wheel 30. One end of the piston 52 extends into the cylinder 51 and is sealed and slidably connected to the cylinder 51, and the other end is fixedly connected to the body of the rail vehicle. The spring 53 is sleeved on the periphery of the piston 52 and the cylinder 51, and the opposite ends of the spring 53 are respectively fixedly connected to the drive shaft 31 and the rail vehicle.

[0070] It can be understood that in this embodiment, when the rail vehicle is traveling at high speed, the drive wheel 30 may bounce with the rail vehicle relative to the beam surface of the track. The present application sets a shock absorber 50 to attenuate vibration, prevents the drive wheel 30 from bouncing up and down relative to the beam surface of the track, and ensures that the drive wheel 30 is always close to the beam surface of the track, thereby maintaining the friction between the drive wheel 30 and the beam surface of the track, and further ensuring that the drive wheel 30 provides sufficient driving force to the roller brush 20.

[0071] It should be noted that, in the above embodiment, the number of the driving wheels 30 is two, and the number of the shock absorber 50 is one, while in another embodiment (see Figure 8 As shown in the structural schematic diagram of the snow removal device 100 provided in one embodiment of the present application, the number of shock absorbers 50 can be only one. In this case, the shock absorber 50 is arranged between the two driving wheels 30 along the length direction of the driving shaft 31, thereby ensuring the shock absorbing effect of the snow removal device 100 of the present application while reducing the manufacturing cost.

[0072] In one embodiment, the track is a monorail, and the axial dimension of the roller brush 20 is greater than the width dimension of the beam surface of the monorail. It can be understood that, based on the track being a monorail, by setting the axial dimension of the roller brush 20 to be greater than the width dimension of the beam surface of the monorail, it is ensured that the roller brush 20 can fully cover the beam surface of the monorail, and when the roller brush 20 rotates and works, most of the snow on the beam surface of the track can be lifted and thrown away to avoid snow accumulation.

[0073] In one embodiment, the track is double-track, and the axial dimension of the roller brush 20 is greater than the maximum width dimension of the double track. It can be understood that based on the double-track track, by setting the axial dimension of the roller brush 20 to be greater than the maximum width dimension of the double track, it is ensured that one roller brush 20 can cover the two beam surfaces of the double track, and when the roller brush 20 rotates and works, the snow on the two beam surfaces of the double track can be lifted and thrown, and at the same time, the components in the snow removal device 100 of the present application can be simplified.

[0074] In one embodiment, the track is a double track, the number of driving wheels 30 is two, each driving wheel 30 contacts the beam surface of one track and is drivingly connected to one end of the roller brush 20. It can be understood that based on the double track, by setting two driving wheels 30 to contact the two beam surfaces of the double track, and using the two driving wheels 30 to drive the roller brush 20 to rotate, the rotation rate of the roller brush 20 can be increased while improving the stability of the rotation of the roller brush 20, thereby improving the snow sweeping effect.

[0075] In one embodiment, the track is a single track, and the number of driving wheels 30 is two, and the two driving wheels 30 are arranged on both sides of the beam surface of the track along the width direction of the single track. Using two driving wheels 30 to drive the same roller brush 20 to perform snow sweeping operations on the same beam surface can improve the stability of the roller brush 20 and also increase the rotation speed. It can be understood that the number of driving wheels 30 in the above embodiment is only used as an exemplary introduction.

[0076] In one embodiment, the fixed bracket 10 of the present application includes a support arm 13 and a connecting arm 14. The support arm 13 is connected between the driving shaft 31 of the driving wheel 30 and the rail vehicle. The number of the connecting arms 14 is two. The two connecting arms 14 are arranged on both sides of the roller brush 20 along the axial direction of the roller brush 20, and are respectively connected between the rotating shaft 21 of the roller brush 20 and the support arm 13. It can be understood that by arranging the support arm 13 in the fixed bracket 10, the support arm 13 is used to support and connect the driving wheel 30 and the rail vehicle. At the same time, the connecting arms 14 are arranged on both sides of the roller brush 20 along its own axial direction, and the rotating shaft 21 of the roller brush 20 and the support arm 13 are connected by the connecting arms 14, which can improve the rotation stability of the roller brush 20, and at the same time prevent the roller brush 20 from tilting and shaking, etc., to ensure that the roller brush 20 can always be in contact with the beam surface of the track.

[0077] It should be noted that the number of supporting arms 13 and driving wheels 30 in the above embodiment is only an exemplary introduction, and the number of supporting arms 13 and driving wheels 30 can be one or more, that is, the number of supporting arms 13 and driving wheels 30 can be adaptively adjusted according to the actual application scenario. Fig. 9 In the structural diagram of the snow removal device 100 provided in another embodiment of the present application, there is only one driving wheel 30 and two support arms 13. In this case, no matter whether the track is a single track or a double track, the one driving wheel 30 can realize the snow removal operation on the track beam surface. At the same time, in order to ensure the stability of the snow removal device 100, the driving wheel 30 is set between the two support arms 13 along the length direction of the driving shaft 31, and the two support arms 13 are simultaneously connected between the driving shaft 31 and the rail vehicle. Fig.10 In the structural diagram of the snow removal device 100 provided in another embodiment of the present application, there are two driving wheels 30 and one support arm 13. In this case, whether the track is a single track or a double track, the two driving wheels 30 can realize the snow removal operation on the track beam surface. At the same time, in order to ensure the stability of the snow removal device 100, a support arm 13 is set between the two driving wheels 30 along the length direction of the driving shaft 31. Of course, the number of driving wheels 30 and support arms 13 is not limited to the above examples.

[0078] In one embodiment, the fixed bracket 10 in the snow removal device 100 of the present application is fixed to the steering suspension of the rail vehicle. Specifically, the support arm 13 of the fixed bracket 10 is fixed to the steering suspension of the rail vehicle. It can be understood that, based on the fact that the steering suspension is close to the power device of the rail vehicle, fixing the support arm 13 to the steering suspension is conducive to the rail vehicle being able to provide sufficient power to the drive wheel 30. At the same time, it is ensured that when the rail vehicle turns, the roller brush 20 can follow the steering suspension to turn, ensuring that the roller brush 20 of the snow removal device 100 is always in contact with the beam surface of the track, so as to have a good snow removal effect.
