An on-vehicle snow removing apparatus 100 for a rail vehicle according to an embodiment of the present invention is described below with reference to the drawings.

Referring to fig. 1 to 8, a vehicle-mounted snow removing apparatus 100 according to an embodiment of the present invention may include: snow removing element 10, mounting element 20, plurality of links 30, drive member 40 and guide wheel 80.

In particular, the mount 20 may be connected to a rail vehicle. The snow remover 10 has a snow removing position (or working position) and a stowed position (or non-working position), and when the snow remover 10 is in the snow removing position, the snow remover 10 can contact the rail 200, as shown in fig. 3, and move on the rail 200 along with the movement of the rail vehicle to remove snow on the rail 200; as shown in fig. 4, when the snow removing member 10 is located at the stowed position, the snow removing member 10 can be separated from the rail 200, so that the snow removing member 10 is prevented from being worn more severely due to being located at the working position for a long time, and the wear of the snow removing member 10 can be effectively reduced.

The snow removing member 10 can be changed between the retracted position and the snow removing position, so that the snow removing member can better adapt to the change of the beam surface of the rail 200, is convenient for maintenance and replacement operation, and effectively solves the problem of difficulty in replacement and maintenance of a fixed structure in the related art due to narrow operation space.

The mounting member 20 and the snow-removing member 10 may be connected by a plurality of links 30, and specifically, one end of each link 30 may be pivotally connected to the mounting member 20, and the other end of each link 30 may be pivotally connected to the snow-removing member 10, and the plurality of links 30, the snow-removing member 10, and the mounting member 20 may constitute a translation mechanism so that the snow-removing member 10 may be translated. The snow remover 10 may be translated from a snow removing position to a stowed position when the link 30 is pivoted in one direction and the snow remover 10 may be translated from the stowed position to the snow removing position when the link 30 is pivoted in the other direction.

Translation is also referred to herein as translation, or parallel translation, and in particular, when an object is moving, if any given straight line in the object keeps its direction constant throughout the movement, such movement is referred to as translation.

Therefore, the snow removing piece 10 can translate relative to the rail 200 and cannot turn over, so that the snow removing piece 10 can be kept in good contact with the rail 200, for example, the snow removing piece 10 can still be kept parallel to the rail 200 after being translated for multiple times, the contact of the snow removing piece 10 and the rail 200 is good, and a good snow removing effect can be ensured.

A drive member 40 may be provided on the mount 20 and may drive the link 30 to pivot. Therefore, manual operation is not needed, automatic pivoting of the connecting rod 30 can be achieved by controlling the driving part 40, automatic translation of the snow removing piece 10 can be achieved between the snow removing position and the folding position, manual operation is not needed, and the snow removing piece is more convenient and labor-saving to use. Also, the drive member 40 may be connected to a control system of the rail vehicle so that the driver can complete the switching operation of the operating state of the vehicle-mounted snow remover 100 in the driver's cabin, facilitating the integrated design of the vehicle.

As shown in fig. 1 and 5, the guide wheel 80 is attached to the snow removing member 10. In some embodiments of the invention, not shown, idler 80 may also be coupled to mounting member 20. The guide wheels 80 can move on the rails 200 when the snow-removing member 10 is in the snow-removing position. From this, when on-vehicle snow removing device 100 is removing snow, not only snow removing piece 10 can contact and remove with track 200, and guide pulley 80 can roll on track 200 in addition, and on-vehicle snow removing device 100's guidance quality is better, and it is more steady to remove, can further promote on-vehicle snow removing device 100's snow removing effect.

According to the vehicle-mounted snow removing device 100 of the embodiment of the invention, the plurality of connecting rods 30 are arranged to pivotally connect the snow removing member 10 and the mounting member 20, the driving member 40 is adopted to drive the connecting rods 30 to pivot, and the guide wheel 80 is adopted to guide, so that the snow removing member 10 can automatically translate between the snow removing position and the stowing position, the snow removing effect is good, the operation is convenient and flexible, the replacement and the maintenance are convenient, the adaptability of the snow removing member 10 to the beam surface of the rail 200 is improved, and the abrasion can be reduced. The vehicle-mounted snow removal device 100 is simple in structure, convenient to operate and reliable in performance.

As shown in fig. 1 to 8, in some embodiments of the invention, the snow-removing member 10 may be located at a lower height when it is in the snow-removing position than when it is in the stowed position, for example, as shown in fig. 3, the snow-removing member 10 is in the snow-removing position, and as shown in fig. 4, the snow-removing member 10 is in the stowed position. Thus, the snow remover 10 can be lowered from the stowed position to the snow removing position and can be raised from the snow removing position to the stowed position, the snow remover 10 can be brought into contact with or separated from the rail 200 by changing the height, the switching effect is good, and the rail 200 can be better adapted to.

Alternatively, in other embodiments of the invention, the snow removing element 10 may be repositioned without a change in elevation. For example, the snow plow 10 may also translate in a horizontal direction from above the track 200 to one side of the track 200. Thus, the contact and separation of the snow-removing member 10 with the rail 200 can also be achieved, and the snow-removing member 10 is no longer positioned above the rail 200 but is moved to the side of the rail 200 when positioned in the non-snow-removing position, and the height of the vehicle-mounted snow-removing apparatus 100 can be reduced. This is understood by those skilled in the art and will not be described in detail herein.

The structure of the translation mechanism on which the snow removing member 10 is located will be described in further detail below with reference to the drawings.

As shown in fig. 1 to 8, according to some embodiments of the present invention, the snow removing device 100 on a vehicle may further include a first elastic member 60, the first elastic member 60 may be connected to the link 30, and the first elastic member 60 may apply a force to the link 30 that moves the snow removing member 10 to the snow removing position. That is, the link 30 can move the snow-removing member 10 to the snow-removing position under the urging force of the first elastic member 60. Thus, the snow remover 10 can realize the switching between the two positions under the common driving of the driving part 40 and the first elastic part 60, and the switching is reliable. Moreover, when the snow removing member 10 is located at the snow removing position, the first elastic member 60 may be further configured to still apply an acting force to the link 30, so as to increase the stability of the snow removing member 10 at the snow removing position, and the snow removing member 10 can be pressed on the rail 200 with a certain pressure, that is, the snow removing member 10 and the rail 200 may be in interference fit, for example, as shown in fig. 3, a certain interference amount exists between the snow removing member 10 and the rail 200, so that the close contact degree between the snow removing member 10 and the rail 200 can be further improved, which is beneficial to improving the snow removing effect.

It should be noted that, in the snow-removing member 10 whose height can be changed, in addition to the driving force of the driving member 40 and the force of the first elastic member 60, gravity also participates therein. For example, in the embodiment shown in fig. 1 to 8, since the snow-removing member 10 can be moved downward to the snow-removing position, the snow-removing member 10 can be positionally moved under its own weight, the urging force of the first elastic member 60, and the driving force of the driving member 40. When the snow remover 10 moves to the stowed position, the driving force of the driving member 40 can overcome the weight of the snow remover 10 and the force of the first elastic member 60, so that the snow remover 10 can be translated upward to the stowed position.

In addition, the number of the first elastic members 60 is not particularly limited in the present invention, and may be flexibly configured according to the need, for example, one first elastic member 60 may be provided, and may be connected to any one of the links 30. For another example, the number of the first elastic members 60 may be equal to the number of the links 30, for example, as shown in fig. 1, the number of the links 30 and the number of the first elastic members 60 are four, and the four links 30 and the four first elastic members 60 correspond to each other one by one, at this time, each link 30 may be subjected to an elastic force, the forces applied to the plurality of links 30 are more balanced, the translation mechanism moves more stably and reliably, and the smoothness of movement of the snow removing member 10 is increased.

The first elastic member 60 may have various structures, and the present invention is not limited thereto, and as an example, the first elastic member 60 may be a torsion spring (or called torsion spring), the connecting rod 30 and the mounting member 20 may be pivotally connected by a rotating shaft 21, the torsion spring may be sleeved on the rotating shaft 21, one end of the torsion spring may be connected to the connecting rod 30, and the other end of the torsion spring may be connected to the mounting member 20, as shown in fig. 1 to 8. Thus, the vehicle-mounted snow removing device 100 is more compact in structure and more convenient to assemble, and the urging force provided by the torsion spring can be more aligned with the pivoting direction of the link 30, facilitating the pivoting of the link 30.

As shown in fig. 1 to 8, according to some embodiments of the present invention, the mounting member 20 may extend in a long bar shape along a horizontal direction, and the number of the links 30 may include four, and the number of the torsion springs may also include four, and the four torsion springs correspond to the four links 30 one by one, wherein two links 30 are connected to both sides of one end of the mounting member 20 in a length direction, and wherein the other two links 30 are connected to both sides of the other end of the mounting member 20 in the length direction. Therefore, the mounting part 20, the connecting rod 30 and the snow removing piece 10 can form a more stable translation mechanism, and the snow removing piece 10 is more reliably mounted and moves more stably.

In practical use, the mounting member 20 may extend in a long strip shape along the extending direction of the rail 200 (for example, the front-back direction shown in fig. 1), the four links 30 are distributed in a substantially rectangular shape, the two links 30 located at the front side are located at the left and right sides of the front end of the mounting member 20, respectively, and the two links 30 located at the rear side are located at the left and right sides of the rear end of the mounting member 20, respectively.

Further, the vehicle-mounted snow removing apparatus 100 may further include a connecting rod 50, as shown in fig. 1 to 8, the connecting rod 50 may extend in a horizontal direction, for example, in a width direction (for example, a left-right direction shown in fig. 1) of the rail 200, both ends of the connecting rod 50 may be connected to two of the links 30, and the connecting rod 50 may be moved by the driving of the driving member 40, so that the links 30 may be pivoted by the driving of the connecting rod 50. Therefore, the driving part 40 can transmit the driving force to the two connecting rods 30 through the connecting rod 50, and the other connecting rods 30 can be driven, so that the direct connection with the two connecting rods 30 is not needed, the structure is simpler, and the driving effect is better.

Note that, when the vehicle-mounted snow removing apparatus 100 does not have the connecting rod 50, the driving member 40 can directly drive the link 30 to move. The driving part 40 can drive only one of the connecting rods 30 to pivot, and can also drive a plurality of connecting rods 30 to move at the same time, and the arrangement can be flexibly set according to actual conditions.

In the embodiment in which the vehicle-mounted snow removing apparatus 100 includes torsion springs, both ends of the connecting rod 50 may also be connected to two of the torsion springs, for example, as shown in fig. 1 and 6, torsion springs connected to two links 30 located on the rear side may be connected to both left and right ends of the connecting rod 50, and the driving member 40 may transmit the driving force to the links 30 through the connecting rod 50 so that the links 30 may pivot. At this time, the two torsion springs can be connected through the connecting rod 50, so that the force transmission effect of the vehicle-mounted snow remover 100 is better, and the deformation is more balanced.

The structure associated with idler 80 is described in further detail below.

According to some embodiments of the invention, the guide wheel 80 is configured to be spaced apart from the rail 200 when the snow remover 10 is in the stowed position, as shown in fig. 4. Therefore, when the vehicle-mounted snow removal device 100 is not removing snow, the snow removing member 10 and the guide wheel 80 can be spaced apart from the rail 200, so that the abrasion of the guide wheel 80 can be reduced, and the service life of the vehicle-mounted snow removal device 100 is prolonged.

As shown in fig. 3, the lower end of the snow-removing member 10 may be lower than the lower end of the guide wheel 80 when the snow-removing member 10 is in the snow-removing position. Therefore, when the snow removing member 10 contacts the rail 200, the snow removing member 10 can be in interference fit with the rail 200 to be stopped against the rail 200 with a large pressure, and the guide wheel 80 can be slightly stopped against the rail 200 to roll, and the pressure between the snow removing member 10 and the rail 200 is greater than the pressure between the guide wheel 80 and the rail 200, so that the snow removing member 10 can be in closer contact with the rail 200, the snow removing effect is improved, and the abrasion of the guide wheel 80 can be reduced while the guiding effect is ensured.

It should be noted that the description here that the lower end of the snow remover 10 is lower than the lower end of the guide wheel 80 is made in the case that the vehicle-mounted snow removing apparatus 100 is in a free state, that is, assuming that the snow remover 10 moves to the snow removing position but does not contact the rail 200, at this time, the snow remover 10 does not engage the rail 200, the lower end of the snow remover 10 is lower than the lower end of the guide wheel 80 in the free state, when the snow remover 10 contacts the rail 200, the snow remover 10 is pressed by the rail 200 and has an interference fit with the rail 200, and for some snow removers 10 having flexibility, at this time, the snow remover 10 is slightly deformed, so that the lower end of the snow remover 10 can approximately approach the lower end of the guide wheel 80 and stop on the rail 200.

The difference in height between the lower end of the snow-removing member 10 and the lower end of the guide wheel 80 may be specifically determined according to actual circumstances, for example, in some embodiments of the present invention, the difference in height between the lower end of the snow-removing member 10 and the guide wheel 80 may be set to be within 3mm, for example, 1mm or 2mm, and the like, which makes it easier to keep the snow-removing member 10 and the guide wheel 80 in good contact with the rail 200 at the same time, and to avoid damage to the snow-removing member 10 due to excessive force between the snow-removing member 10 and the rail 200.

In alternative embodiments of the present invention, the guide wheel 80 may be configured to move upward when encountering an obstacle to avoid the obstacle. Because snow removing member 10 usually has certain flexibility, when meetting comparatively hard barrier, snow removing member 10 can be through certain deformation of self in order to pass through the barrier, and guide pulley 80 is usually comparatively rigid, can not realize dodging through flexible deformation, through setting up guide pulley 80 to can certain displacement of upwards moving when meetting the barrier, in order to dodge the barrier, increase guide pulley 80's trafficability characteristic, so not only can reduce guide pulley 80's damage, can make rail vehicle move more smoothly moreover.

It should be noted that the guide wheel 80 may be configured to move upward to avoid an obstacle when the snow remover 10 is in the snow removing position, or may be configured to move upward to avoid an obstacle when the snow remover 10 is in the stowed position. In the case where the guide wheel 80 is in contact with the rail 200, the guide wheel 80 may be lowered again to be in contact with the rail 200 after moving up through the obstacle. In the case where the guide wheel 80 is separated from the rail 200, the guide wheel 80 may be lowered again to a position separated from the rail 200 after moving up through an obstacle. That is, the guide wheel 80 can be returned to the position where it is not moved up after passing over an obstacle, so that it is convenient to use without manually returning the guide wheel 80.

Further, in some embodiments of the present invention, the snow remover 10 is configured and adapted to move upward by the guide wheel 80 when the guide wheel 80 moves upward. Thus, not only can the guide wheel 80 move up to avoid a harder obstacle, but also the snow-removing member 10 can move up, so that the risk of damage to the snow-removing member 10 can be reduced and the running stability of the vehicle-mounted snow-removing device 100 can be further improved.

Fig. 1 to 5 show one embodiment of a vehicle-mounted snow removing apparatus 100 according to an embodiment of the invention. As shown in fig. 1 to 5, the snow removing device 100 on-vehicle may further include a shaft 81, one end of the shaft 81 may be pivotably connected to the snow removing member 10, and the other end of the shaft 81 may be pivotably connected to the guide pulley 80, wherein both the pivot axis of the shaft 81 and the pivot axis of the guide pulley 80 extend in the horizontal direction. From this, guide pulley 80 not only can roll on track 200, and guide pulley 80 is when meetting the barrier, and the pivot of snow removing part 10 relatively can be driven to guide pulley 80 moves upwards to, after crossing the barrier, under the action of gravity, axostylus axostyle 81 antiport, and guide pulley 80 can reply to the original position, and it is more convenient to use and guide pulley 80 work is more reliable and more stable.

Further, the vehicle-mounted snow removing device 100 may further include a second elastic member 82, as shown in fig. 1 to 5, the second elastic member 82 may be connected to the shaft 81, and the second elastic member 82 may apply a force to the shaft 81 to urge the guide wheel 80 against the rail 200, so that the guide wheel 80 can be more stably stopped against the rail 200 to move, further improving the guiding effect.

Furthermore, the vehicle-mounted snow removing device 100 may further include a limiting member 83, as shown in fig. 3 to 5, when the guide wheel 80 contacts the rail 200, the limiting member 83 may abut against the shaft 81, so that the shaft 81 cannot rotate downward, and the guide wheel 80 may be stably fixed at a height position where the guide wheel contacts the rail 200, at this time, the limiting member 83 may play a role of limiting the guide wheel 80 downward, and may balance an acting force of the second elastic member 82, so as to prevent the guide wheel 80 from abutting against the rail 200 with a larger pressure due to an excessive elastic force of the second elastic member 82. Alternatively, the stopper 83 may be a stopper plate, which may extend in the horizontal direction and be disposed adjacent to one end of the shaft 81.

As shown in fig. 1 to 5, the second elastic member 82 may be a coil spring, a lower end of the second elastic member 82 may be connected to the shaft 81, and an upper end of the second elastic member 82 may be connected to the mounting member 20. Therefore, the spiral spring can apply a downward acting force to the guide wheel 80, so that the guide wheel 80 can be stably contacted with the track 200, and the guide wheel 80 can be timely restored after jumping.
