Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removing device for a vehicle running on a tire running road surface of a U-shaped wall track.

[0002]

2. Description of the Related Art Conventionally, as a vehicle traveling on a tire traveling road surface of a U-shaped wall track, for example, a new transportation system vehicle equipped with tires such as an electric drive vehicle is known. When a new transportation system vehicle travels on a tire traveling road surface of a U-shaped wall track, a measure against snowfall is required.

[0003] It is conceivable to mount a rotary snow removal device or a Russell type snow removal device used for snow removal on railways and roads in regions where the amount of snow is large in new transportation system vehicles. The Russell type snow removing device is used when the amount of snow is relatively small, and pushes snow in a railway line to both sides of the railway line. On the other hand, the rotary snow removal device is a relatively snowy place where the snow is gathered by the wings to fly to the center and fly far away when the amount of snow is large or the amount of snow accumulated on the side of the railway line increases. It is used for the purpose of throwing snow. The Russell type snow removing device is used while the snowfall is small, and when the snowfall increases, the rotary snow removing device is used even if the snow removal speed is low.

[0004] New transportation system vehicles are used in rural areas where the amount of snowfall is small, and because of the structure of the U-shaped wall track, the new transportation system vehicles run on snow under conditions such as running in urban areas and overpasses. There is a special feature that snow cannot be thrown outside the road. In rural areas where the amount of snow is small, even if a rotary type snow removing device or a Russell type snow removing device is mounted on a new transportation system vehicle, the equipment becomes large-scale, which is not preferable.

[0005] It is required to mount a snow removing device, which can be easily mounted on a U-shaped wall track, in a vehicle of a new transportation system.
As described above, when a small amount of snow accumulates, it is difficult to directly apply a rotary or plow snow removal device conventionally used in railways or automobiles on a U-shaped wall track on which a new transportation system vehicle runs. It is. Therefore, as a snow removal measure, the snow discharged from the road surface on which the tires of the new transportation system vehicle run in the U-shaped wall track is deposited or melted in the U-shaped wall track. For snow melting,
There is snow melting by water or hot water and snow melting by spraying a snow melting agent (anti-freezing agent). However, snow melting by water or hot water requires water and hot water supply equipment in addition to wastewater treatment equipment, which means huge initial investment costs. There's a problem. For this reason, the snow in the U-shaped wall track has to be removed manually or the operation of the new transportation system vehicle has to be suspended.

Therefore, for example, conventionally, in a new transportation system vehicle, it is conceivable to use an obstacle mounted on both heads for snow removal. This will be described below with reference to FIGS. In the figure, a new transportation system vehicle 101 is configured by knitting a plurality of sub-vehicles 101A, and runs on a U-shaped wall track 102. U-shaped wall track 1
02 is a tire running road surface 102A formed of a bottom wall, and side walls 102B,
102B. New transportation system vehicle 1
01, the rubber tire 103 of each sub vehicle 101A is
Rolling on the tire running road surface 102A, the guide wheels 104, 1
04 is guided by the side walls 102 and 102B.

[0007] A support member 105 is provided at the front end of the leading sub-vehicle 101A of the new transportation system vehicle 101, and left and right obstacles 106 and 107 are mounted on the support member 105. The left and right obstacles 106 and 107 are arranged in a plane C shape. Each of the obstacles 106 and 107 is a plate-shaped member, which is located in front of the left and right tires 103 and 103, and removes an obstacle on the tire traveling road surface 102A.
The lower ends 106A and 107A of the obstacles 106 and 107 are located at predetermined positions above the tire traveling road surface 102A.

When snow is accumulated on the tire running road surface 102A, the left and right obstacles 106 and 107 are used as plows for snow removal.

[0009]

However, in the new transportation system vehicle 101, when the snow is removed, the two obstacles 106, 1 are removed.
07 is used as a plow.
7, the lower end 106A, 107A of the tire running road surface 102
A does not come into contact with A, so snow on the tire running road surface 102A cannot be removed, snow remains on the tire running road surface 102A, and the rubber tire 103 runs on this, so that it is turned into snow and frozen. Will be. In order to perform snow removal, the obstruction devices 106 and 107 do not satisfy the snow removal function.

On the other hand, the rotary and plow snow removing devices described above satisfy the snow removing function. However, in the case of snow with a small amount of snow, the size is large and is not preferable. There is a need for a simple snow removal device that can replace rotary and plow snow removal devices. The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a snow removing device for a vehicle that can remove snow with a simple structure corresponding to a small amount of snow accumulated on a tire traveling road surface. It is.

Features.

According to a second aspect of the present invention, in the snow removing device for a vehicle according to the first aspect, when the left and right plows on the traveling direction side of the train are in the lower snow removal position, the left and right plows on the opposite side of the traveling direction are not moved. It is characterized by being in an upper floating position. The invention described in claim 3 is claim 1 or claim 2.
The snow removal device for a vehicle according to claim 1, wherein the plow is a brush.

According to a fourth aspect of the present invention, in the snow removing device for a vehicle according to the third aspect, the brush is inclined with its upper end facing forward, and the cutting angle of the brush with respect to the tire traveling road surface is 90.
Less than degree. According to a fifth aspect of the present invention, in the snow removing device for a vehicle according to the third or fourth aspect, a snow removal plate is provided integrally with the brush and located in front of the brush. The brush is located above the lower surface of the tip of the brush.

According to a sixth aspect of the present invention, in the snow removing apparatus for a vehicle according to any one of the third to fifth aspects, a stopper that contacts a rear surface of the brush is provided on the lifting mechanism or the support member after the brush. It is characterized by the following. Claim 7
According to a third aspect of the present invention, in the snow removal device for a vehicle according to the third aspect, the brush is formed by bundling a synthetic resin wire.

According to an eighth aspect of the present invention, in the vehicle snow removing apparatus according to the third aspect, the brush is formed by binding bamboo strands.

(Function) In the first aspect of the present invention,
During snow removal, the left and right plows are lowered and are at the lower snow removal position. The lower end of the plow is in contact with the tire running road surface. The left and right plows remove the snow on the tire running road surface, and the snow in front of the tire is blown to the side of the vehicle.

According to the second aspect of the present invention, only the left and right plows on the traveling direction side of the train set required for snow removal are located at the lower snow removal positions, and the lower ends of the left and right plows contact the tire running road surface to perform the snow removal work. Done. On the other hand, since the left and right plows on the opposite side in the traveling direction are at the upper floating positions, the left and right plows on the opposite side in the traveling direction do not receive resistance from the tire traveling road surface.

According to the third aspect of the present invention, the lower surface of the tip of the brush is softly contacted with the tire traveling road surface. According to the fourth aspect of the present invention, since the cutting angle is less than 90 degrees, the elasticity of the brush is effectively used, and the tension of the brush when the lower end surface of the brush is in contact with the tire traveling road surface is strong. Become.

According to the fifth aspect of the present invention, since the snow flows at right angles to the strands of the brush and horizontally in the horizontal direction, the brush is a factor inhibiting the flow. Since the snow is caused to flow laterally by the snow plate, the resistance of the snow from the brush is reduced, and the flow of the snow is smooth. According to the sixth aspect of the invention, the rearward movement of the brush is restricted by the stopper. Particularly, when a large amount of snow is pressed by the brush, the resistance of the brush prevents the wire of the brush from bending backward.

In the invention according to the seventh aspect, since the surface of the wire is smooth, the snow slides well.
According to the eighth aspect of the present invention, since the bamboo wire is strong, the snow removal is performed while the lower end of the brush is in contact with the tire traveling road surface.

[0021]

Embodiments of the present invention will be described below with reference to the drawings.

According to FIG. 1 to FIG.
A snow removal device for a vehicle according to the embodiment of the invention described will be described by taking a new transportation system vehicle as an example of the vehicle. The structure of the U-shaped wall track on which the new transportation system vehicle travels is the same as that described in the conventional example, and the same components are denoted by the same reference numerals and description thereof will be omitted. In the figure, a new transportation system vehicle 1 has six sub vehicles 2
This is a train set in which A, 2B, 2C, 2D, 2E, and 2F (the reference numeral 2 is used when generically used) are connected in series.

The sub-vehicle 2 has a frame 3A forming the bottom of the vehicle body 3, and rubber tires 4, 4, 4, and 4 disposed on the front, rear, left and right sides of the frame 3A. At the front and rear ends of the frame 3A of the sub-vehicle 2, support members 5 and 6 composed of horizontal members are respectively disposed at lower ends thereof, and guide wheels 7 and 7 are provided at both left and right ends of each support member 5, respectively. It is installed.

The new transportation system vehicle 1 runs on a U-shaped wall track 102. Each tire 4 of the sub-vehicle 2 rolls on a tire running road surface 102A, and the guide wheels 7, 7, 7, 7 are guided by both side walls 102B, 102B. A snow removing device 9 is mounted on each of the support members 5 of the leading sub-vehicle 2A and the rear sub-vehicle 2F via an elevating mechanism 8. The snow removing device 9 of the leading sub-vehicle 2A and the snow removing device 9 of the back sub-vehicle 2F
Is the same structure. The elevating mechanism 8 includes a left elevating unit 8A and a right elevating unit 8B that are arranged symmetrically to the left and right with respect to the center line L. The snow removing device 9 includes a left-side plow 10 and a right-side plow 11 symmetrically disposed on the center line L, and has a flat C-shape. The left plow 10 and the right plow 11 have the same structure, and the details of each component of the support member 5, the lifting mechanism 8, and the left plow 10 will be described using the left plow 10 as an example.

A vertical plate 13 is attached to the support member 5 via a bracket 12 at an angle of 45 degrees with respect to the support member 5 (FIG. 4).
(Shown in plan view). A cylinder support plate 14 is attached to the upper end of the vertical plate 13.
5A is rotatably supported.

The tip 1 of the rod 15B of the air cylinder 15
The lower center of the movable member 6 is pivotally mounted on 5C. The movable member 16 includes a plate 16A and four slide members 16B fixed to the plate 16A. First plate pieces 17, 17 are fixed vertically at the right and left upper ends of the vertical plate 13, and second plate pieces 18, 18 are provided at the left and right lower ends of the vertical plate 13.
Are fixed vertically.

On the left and right end surfaces 13A, 13A of the vertical plate 13, levers 19, 19 are fixedly mounted, and at the ends of the levers 19, 19, a stopper 20 made of a bar is attached. This stopper 20 is parallel to the vertical plate 13. A guide rod 21 is fixed vertically from each first plate piece 17 to the second plate piece 18. The four slide members 16B are slidably fitted in the guide rod 21 in the vertical direction.

A compression spring 22, 22 is mounted between the lower slide member 16B, 16B and the second plate 18, 18, and the movable member 6 is urged upward by the compression spring 22, 22. , And floated upward (the state of FIGS. 5 to 8). On both left and right sides of the vertical plate 13,
3 is fixed by welding. One end of each of the link members 24, 24 is connected to the receivers 23, 23 (only one is shown in FIG. 7) via bolts 25, 25, and the receivers 23, 23 and the link members 24, 24 are formed by knock pins. Stopper 26,
26 is fixed.

At the other end of each of the link members 24, 24, a brush bracket 27 having an L-shaped cross section is provided with bolts 28, 28.
Has been fixed through. A frame 27A is provided on the lower surface of the brush bracket 27. The left plow 10 and the right plow 11 are each composed of a brush 29 whose base end is inserted into the frame 27A and fixed in a crimped state. The brush 29 is formed by bundling a plurality of smooth strands 29A made of a synthetic resin, and the front surface 29B of the brush 29 which is in contact with snow is formed in a planar shape.

The left and right plows 10 and 11 made of brushes are inclined with their upper ends facing forward to form a cutting angle θ (V) with respect to the tire running road surface 102A. The cutting angle θ (V) of the left and right plows made of brushes is shown in FIG. 7, and a value of 85 degrees is selected in the embodiment of the present invention.
It can be selected within the range of 81 degrees or more to less than 90 degrees, and is determined by the material and structure (bundling method, rigidity) of the brush 29, and the like. Incidentally, when a snow removal test was conducted at a cutting angle of 80 degrees, it was confirmed that the stiffness of the brush 29 was weak and the elasticity of the brush 29 could not be used effectively. When a snow removal test was performed at a brush cutting angle of 90 degrees, the wire 29A of the brush 29 pressed the tire running road surface 102A vertically,
It has been confirmed that the elasticity of the brush 29 cannot be obtained.
By setting the cutting angle θ (V) of the brush 29 within the above range, the cutting angle θ (V) of the brush 29 is always used,
The snow can be cut by pressing the tire traveling road surface 102A. That is, since the cutting angle of the brush 29 is in the range of 81 degrees or more to less than 90 degrees, the elasticity of the brush 29 is effectively used.

Within the range of the cutting angle θ (V) of the left and right plows 10 and 11 made of brushes,
The tension of the brush 29 in the state where 9C is in contact with the tire traveling road surface 102A is increased. As a result, although the U-shaped wall track 102 on which the new transportation system vehicle 1 travels is not necessarily flat and has a joint portion, the new transportation system vehicle 1 has a joint portion of the tire traveling road surface 102A when traveling. Even if the tire 4 vibrates due to unevenness and the vertical movement of the tire 4 and the vertical movement of the support members 5 and 6 occur, the cutting angle θ (V) of the left and right plows 10 and 11 made of brushes is
These vertical movements are absorbed.

Also, left and right plows 10, which are composed of brushes,
Numeral 11 denotes a protruding angle α formed between the left and right plows 10, 11 and the center line L in plan view.
In the, the lateral flow of snow is emphasized as follows, and 45 degrees is adopted. The relationship between the propulsion angle α and the flow of snow will be described. In general, when the propulsion angle α is small, the lateral force (the force received from snow in a direction perpendicular to the traveling direction of the vehicle) increases,
If the snow flow improves, while the propulsion angle α is large, the lateral force decreases, and the snow flow deteriorates. Therefore, from the viewpoint of snow removal, the flow of snow can be improved by reducing the propulsion angle α, but this is not preferable because the lateral force increases. That is, a lateral force acts on the leading sub-vehicle 2A due to snow removal resistance, and a moment is generated around the position of the center of gravity of the vehicle, so that the leading sub-vehicle 2A is turned right or left. Further, reducing the propulsion angle α causes a problem that the length of the brush 29 increases.
Therefore, when the propulsion angle, the lateral force, the total length of the brush 29, and the flow of snow are comprehensively considered, the balance of the functions is in a good state near the propulsion angle of 55 degrees.

On the premise of such a design condition, as described above, in the embodiment of the present invention, the propulsion angle of 45 degrees is adopted with emphasis on the flow of snow, and the snow removal resistance and the lateral force become equal. I have. And the above-mentioned bracket 12 and vertical plate 1
3, movable member 16, air cylinder 15, guide rod 2
The left elevating part 8A is constituted by the receiving parts 23, 23, the brush bracket 27 and the like. The right lifting unit 8B has the same structure as the left lifting unit 8A.

The left plow 10 is located in front of the left tire 4. On the other hand, the right plow 11 is located in front of the right tire 4. The resistance of snow is
It is received by the first plate pieces 17, 17 via the slide members 16B, 16B and the guide rods 21, 21. Further, a snow removal plate 30 is provided at the tip of the brush bracket 27 in front of the brush 29 so as to be integral with the brush 29, and the snow removal plate 30 is disposed substantially parallel to the front surface 29 </ b> B of the brush 29. Have been. The lower end 30A of this snow removal plate 30
Are located above the lower end surface 29C of the brush 29. Therefore, when viewed from the front, the front surface 29B of the brush 29 is almost covered with the snow removal plate 30, but only the lower portion of the brush 29 is exposed to the front.

Next, the operation of the embodiment of the present invention will be described. As shown in FIG. 3, a case where the new transportation system vehicle 1 moves to the right in the drawing will be described.
5 to 8 show the leading sub-vehicle 2 on the traveling direction side.
A shows a state in which the left and right plows 10 and 11 (brushes 29) of the sub-vehicle 2F at the back of the sub-vehicle 2F on the opposite side to the traveling direction have risen. When a small amount of snow accumulates on the tire traveling road surface 102A, the operator instructs the traveling direction of the train at the driver's seat, the air cylinder 15 is operated by a control circuit (not shown), and the left and right plows 10 and 1 of the leading sub-vehicle 2A.
1 descends to the lower snow removal position.

Here, the downward stroke of the brush 29 by the air cylinder 15 corresponds to the tire 29 on the tire running road surface 1.
When the lower surface 29C of the tip of the brush 29 is lowered to be larger than the floating amount S from 02A, the brush 29 is in a curved state, and the pressing force against the tire traveling road surface 102A is secured. Therefore, the brush 29 has sufficient strength that the lower end surface 29C of the brush 29 is in soft contact with the tire traveling road surface 102A, and that the posture of the brush 29 is maintained. In addition, the air pressure in the air cylinder 15 is reduced, and the pressing force against the tire traveling road surface 102A can be adjusted. Thus, the brush 29 is raised with respect to the unevenness of the tire running road surface 102A and the like, and has a structure capable of absorbing the unevenness.

In this state, the snow removing operation is performed. That is, with the plows 10 and 11 on the left and right sides of the sub-vehicle 2A, the snow in front of the tires 4 and 4 is blown to the side of the new transportation system vehicle 1 with the plows 10 and 11 of the sub-vehicle 2A. Deposited on both sides. This protects the functions of facilities such as a vehicle control cable (not shown) at the center of the tire traveling road surface 102A.

Here, in the snow removing operation, the snow is brush 2
The brush 29 is a factor that hinders the flow of snow, because the brush 29 flows at a right angle and horizontally in the horizontal direction with respect to the element wire 29A. Therefore, as described above, by attaching the snow removal plate 30 to the tip of the brush 29 for shaving snow on the tire running road surface 102A, snow is caused to flow laterally by the snow removal plate 30,
The resistance of the snow from the brush 29 is reduced, and the flow of the snow is smooth. In addition, since the surface of the wire 29A of the brush 29 is smooth, the snow slides well. further,
The front surface 29B of the left and right brushes 29 on which the snow hits is flat and has no uneven surface, so that when the snow flows sideways, the snow flows smoothly sideways without being caught on the front surface 29B of the brush 29. .

In the snow removing operation, the brush 29 receives a pressing force from the snow.
The rearward movement of the wire 9 is restricted, and particularly when a large amount of snow is pushed, the resistance prevents the wire 29A of the brush 29 from bending backward. When a failure occurs in the air system, the brush 29 is automatically raised by the compression springs 22 to ensure safety.

On the other hand, the plows 10 and 11 on the opposite side of the traveling direction
Is raised, the plows 10 and 11 of the occipital sub-vehicle 2F on the opposite side of the traveling direction are separated from the tire traveling road surface 102A and do not receive resistance from the tire traveling road surface 102A. As a result, the plows 1 on both ends of the train
Of the plows 0 and 11, only plows necessary for snow removal can be used.

In the case where the amount of snow falling is several times consecutively and the amount of snow is large, the snow is removed manually. According to the above configuration, the following effects can be obtained. First, left and right plow 1
Since 0 and 11 are vertically movably mounted on the support member 5 via the elevating mechanism 8, the snow removing device 9 can be configured with a simple structure, and a small amount of snow is removed from the tire traveling road surface 102A.
When piled up, snow can be easily removed.

Second, the left and right plows 1 on both heads of the train set
Of the plows 0 and 11, only the plows 10 and 11 necessary for snow removal can be used. Third, since each of the plows 10 and 11 is made of a brush, the lower end surface 2 of the brush 29 is
9C can be brought into soft contact with the tire running road surface 102A, and the brush 29 does not receive any impact force or resistance from the tire running road surface 102A,
Snow can be reliably removed from above.

Fourth, since the cutting angle of the brush 29 is less than 90 degrees, the elasticity of the brush 29 can be used effectively, and the lower end surface 29C of the brush 29
The tension of the brush 29 in the state of being in contact with 2A is strengthened, and snow removal by the brush 29 can be reliably performed.

Therefore, the new transportation system vehicle 1 may vibrate due to the unevenness of the joint portion of the tire traveling road surface 102A during traveling, and the vertical movement of the tire 4 and the vertical movement of the support member 5 may occur. These vertical movements can be absorbed in the range of the cutting angle. Fifth, snow can be reliably eliminated. Sixth, when fresh snow is pushed, snow flows smoothly to the side, but when wet snow is pushed, snow does not flow to the side and snow may accumulate on the front surface 29B of the brush 29, which can be prevented.

Seventh, the present invention has the effect of reliably removing snow. In the present embodiment, the left and right plows 10 and 1 of the leading sub-vehicle 2A on the side of the traveling direction of the train are described.
1 descends, and the sub-vehicle 2F at the back of the head on the opposite side
The case where the left and right plows 10 and 11 are raised has been described. In FIG. 3, when the train is traveling in the left direction in the drawing, the rear sub-vehicle 2F which is on the traveling direction side of the train is The left and right plows 10 and 11 descend, and the left and right plows 1 of the leading sub-vehicle 2A on the opposite side in the traveling direction.
It can be applied to the case where 0 and 11 are rising.

In the present embodiment, the brush 2
9, the stopper 20 that contacts the rear surface of the brush 29
Has been described in connection with the lifting mechanism 8,
A stopper may be provided on the support member 5 via a suitable bracket. Further, in the present embodiment,
When the snow removal test was performed at a cutting angle of 80 degrees, it was found that the stiffness of the brush 29 was weak. However, depending on the material of the brush 29 or the diameter of the wire material 29A, the stiffness of the brush 29 was less than 80 degrees. Is strong.

In this embodiment, a horizontal member is used as the support member 5. However, a bracket other than the horizontal member is provided on the vehicle body 3 downward, and the left and right plows 10, 11 are attached to the bracket. Can also be attached.

And, in the present embodiment,
The brush is configured by bundling strands made of synthetic resin, but the brush can also be configured by bundling strands made of bamboo. Since the bamboo wire is stiff, the lower end of the brush is in contact with the tire running road surface. With the bamboo wire, snow can be removed from the tire running road surface. And
Further, in the present embodiment, a brush has been described as an example of the plow, but the present invention is not limited to this, and may be a rubber plate, for example.

[0049]

According to the first aspect of the present invention, since the left and right plows are vertically movably mounted on the support member via the elevating mechanism, when a small amount of snow is piled up on the tire running road surface, a simple operation can be achieved. The structure has the effect of removing snow. Claim 2
According to the invention described above, there is an effect that only the plows necessary for snow removal can be used among the left and right plows of both heads of the train.

According to the third aspect of the present invention, since the plow is a brush, the lower surface of the tip of the brush can be softly brought into contact with the tire running road surface, and the brush receives no impact force or resistance from the tire running road surface. This has the effect of reliably removing snow on the tire running road surface. According to the fourth aspect of the present invention, since the cutting angle of the brush is less than 90 degrees, the elasticity of the brush can be effectively used, and the lower surface of the tip of the brush is in contact with the tire traveling road surface. The tension of the brush is increased, and snow removal with the brush can be reliably performed. As a result, when the vehicle is running, it vibrates due to the unevenness of the joint portion on the tire running road surface,
The vertical movement of the tire and the vertical movement of the support member may occur, but within the range of the cutting angle of the brush, there is an effect that these vertical movements can be absorbed.

According to the fifth aspect of the present invention, there is an effect that snow can be reliably removed. According to the invention as set forth in claim 6, when fresh snow is pushed, snow flows laterally smoothly. However, when wet snow is pushed, snow does not flow laterally, and snow may accumulate on the front of the brush. It has an effect that can be prevented.
According to the seventh aspect of the invention, there is an effect that snow removal can be surely performed. According to the eighth aspect of the invention, the bamboo element has an effect of removing snow from the tire traveling road surface.
