Abstract

(57) [Abstract] [Purpose] To provide a slip-resistant surface forming device capable of coping with various road surface conditions and not damaging the road surface or damaging the spike pin and the spike roller itself. [Structure] A winding portion 27a of a spike pin 27 is fitted and inserted into one shaft of a pair shaft 25 and a locking portion 27b is locked into the other shaft to perform positioning and rotation regulation. The spike roller 11 has eight pairs of shafts 25 in each of which 8 to 9 spike pins 27 are fitted. Then, with the tip end of the spike pin 27 in pressure contact with the frozen road surface, the spike roller 11 is attached to the shaft 1.
While rotating around 3, the work proceeds in the direction of arrow S to perform the slip prevention surface forming work. When the spike pin 27 directly contacts the road surface because the ice plate on the frozen road is thin or absent, the winding portion 27a of the spike pin 27 elastically deforms to absorb the external force applied to the spike pin 27.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip surface forming apparatus for forming an anti-slip surface on a frozen road in winter, which is often found in cold regions, to prevent a slip accident.

[0002]

2. Description of the Related Art Conventionally, in cold regions, it has been customary to equip an automobile with spiked tires for traveling during the winter. However, since spiked tires cause dust pollution, their use has recently been regulated. For this reason, slip accidents have frequently occurred due to compacted snow and ice burns on the road. The best way to prevent slip accidents is to completely remove snow and ice burns on the road. However, even if the removal of fresh snow is relatively easy, the technology to completely remove ice sheets and ice burns frozen by compressed snow has not been completed yet.

Therefore, there has been proposed a device for preventing a slip accident by making a concave scar on the surface of an ice plate or an ice burn on the road. For example, a large number of spike-shaped projecting members or sharp blade-shaped members are implanted on the surface of a roller, and the roller member (hereinafter, referred to as a spike roller) is mounted on a front portion or a rear portion of the self-propelled vehicle, and the spike roller is rotated. There is a device that forms a slip-preventing surface for preventing slip on a surface of an ice plate or an ice bar on a road by running while being pressed against a road surface. In such an anti-slip surface forming apparatus, conventionally, the spike-shaped protruding member or the blade-shaped member of the spike roller is formed of a material having a high hardness such as steel.

[0004]

However, the thickness and hardness of ice plates and ice burns on the road are not uniform, and there are places where ice plates and ice burns exist, and there are places where they do not. The road surface is ever changing. When a conventional spike roller type anti-slip surface forming apparatus is used for roads having various road surface conditions, there is a problem that a hard spike-shaped projecting member or a blade-shaped member damages the road surface. Further, when the spike roller comes into contact with a step on the road surface, there is a problem that the spike-shaped projecting member or the blade-shaped member may be damaged.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems in the conventional anti-slip surface forming apparatus and to provide an anti-slip surface forming apparatus which can cope with various road surface conditions.

[0006]

According to the present invention, the above-mentioned problems are provided by a spike roller having a large number of spike pins arranged on its outer periphery and rotatably supported, and a drive mechanism for rotationally driving the spike roller. An anti-slip surface forming device having an ice plate on a frozen road by rotating the spike roller in a state where the spike pin is pressed against the freezing road surface and traveling of a self-propelled vehicle on which the anti-slip surface forming device is mounted and supported. In the anti-slip surface forming device for forming the anti-slip pattern on the freezing road by forming the anti-slip pattern, the spike pin has a predetermined elasticity.

According to the present invention, in order to solve the above problems, the spike pin is formed of a single steel wire having a contact portion with a frozen road surface, a winding portion, and a locking portion. I suggest that.

Further, according to the present invention, in order to solve the above-mentioned problem, the spike roller is constituted by a plurality of paired shafts fixedly arranged on substantially concentric circles and the spike pins mounted on the paired shafts. It is proposed that the winding portion of the spike pin is inserted into one shaft of the pair shaft, and the locking portion is locked to the other shaft, whereby the positioning and rotation of the spike pin are restricted.

Further, in order to solve the above-mentioned problems, the present invention proposes that the spike roller is provided so as to be capable of normal rotation and reverse rotation, and the rotation direction can be switched.

[0010]

[Function] Since the spike pin has a predetermined elasticity,
When the spike roller rotates while the spike pin is pressed against the frozen road surface, the spike pin that touches the road surface may bend when the ice plate on the frozen road surface is thin or soft, or where there is no ice plate. It will not deform and damage the road surface. It also prevents the spike pin and the spike roller itself from being damaged when the spike pin comes into contact with a step or the like on the road.

Other functions will be apparent from the description of the embodiments below.

6, a driving force is transmitted by a driving force transmission mechanism including a drive shaft and gears (not shown), and the spike roller 11 is rotationally driven. The driving force transmission mechanism is mounted and supported on the frame 17 of the apparatus body. In this embodiment, a forward rotation drive for rotating the spike roller 11 counterclockwise in the figure and a reverse rotation drive for rotating the spike roller 11 in the opposite clockwise direction are possible. It can be performed from a self-propelled vehicle. In addition,
It is also possible to replace the driving force transmission mechanism with a hydraulic transmission device, and in that case, the same operational effect is exhibited.

The anti-slip surface forming device 10 includes wheels 18 whose height can be adjusted with respect to the road surface. The inner surface of the anti-slip surface forming device 10 is screwed into an outer shaft 19 fixed to the main body frame 17. By rotating the shaft 20 by the pin 21, the wheel 18 mounted on the lower end of the inner shaft 20 is moved up and down to adjust the distance between the device and the road surface. The distance between the device and the road surface can be adjusted by mounting the wheel 18 on a hydraulic, pneumatic or electric actuator and moving it up and down. In that case, the height adjustment with respect to the road surface can be performed from the driver's seat of the self-propelled vehicle. By the way, spike roller 1
Both left and right sides (front side and rear side in the figure) of 1 are covered with side plates 22, and the front and upper sides of the spike roller 11 are covered with a movable cover 23. A hydraulic cylinder 24 is provided between the movable cover 23 and the main body frame 17.
Rotates to open or cover the front and upper portions of the spike roller 11. The movable cover 23 is opened during inspection and repair of the device to facilitate the work. Spike roller 1 that rotates during the operation of the slip prevention surface forming apparatus 10.
The ice pieces scattered from 1 are prevented from scattering outside the device by the side plate 22 and the movable cover 23.

Next, the spike roller 11 of this anti-slip surface forming device will be described.

As shown in FIGS. 2 and 3, a pair of paired shafts 25 are fixedly attached to a total of eight side plates 26. The side plate 26 is a pair shaft 25
2 and 3, only one side is shown in FIGS. A spike pin 27 is fitted on the pair shaft 25. The spike pin 27 is formed by bending a single steel wire after heat treatment, and is designed to have a predetermined elasticity. The spike pin 27 has its winding part 27a fitted into a small-diameter part provided on one of the paired shafts 25 to be positioned, and the centrally extending part 27b of the winding part is fitted to the paired shaft 25.
The other shaft is locked and its rotation is restricted. The spike pin 27 has a winding portion 27a when an external force of a predetermined amount or more is applied to its tip portion (contact portion with the frozen road surface).
Absorbs the external force. The pair of shafts 25 are fitted with eight to nine spike pins 27. The spike pins 2 fitted to the pair of shafts
The position of 7 is gradually shifted. A reinforcing plate 28 is inserted into the paired shaft 25 to connect each shaft and the shaft 13 for reinforcement. The shaft 13 is fixed to the side plate 26 with bolts and nuts. A gear is disposed on the shaft 13 not shown in FIG. 3, and the driving force is transmitted from the driving force transmission mechanism described above. The arrow S in FIG. 2 indicates the traveling direction of the anti-slip surface forming device (the vehicle on which the anti-slip surface forming device is mounted).

FIG. 4 shows a state in which the slip prevention surface forming apparatus 10 of this embodiment is mounted on the self-propelled vehicle 1. The self-propelled vehicle 1 shown in this figure is obtained by removing a snow removing device from a general rotary snow removing vehicle. The anti-slip surface forming device 10 is mounted on a front portion of the self-propelled vehicle 1 by a parallel link 2.
Then, the non-illustrated hydraulic cylinder of the self-propelled vehicle 1 can raise and lower the anti-slip surface forming device 10. The anti-slip surface forming device 10 is raised, and is fed to the work destination with the tip of the spike pin 27 (see FIGS. 2 and 3) of the spike roller 11 separated from the road surface. When the vehicle reaches the work destination, the anti-slip surface forming device 10 is lowered and the device is lowered onto the ice bar on the road surface. Then, the height of the wheel 18 is adjusted to adjust the distance between the device and the road surface. This adjustment is performed in accordance with the thickness and hardness of the ice burn, and is intended to adjust the degree of contact of the spike pins 27 with the ice plate. Then, the spike roller 11 is rotated by the above-described driving force transmission mechanism while traveling in the direction of the arrow S. Then, the tip of the spike pin 27 scratches the ice barn and forms an anti-slip pattern P on the ice plate as shown in FIG. By forming the anti-slip pattern P, the ice burn is roughened, and it is possible to prevent a slip accident of an automobile running on a road.

By the way, an ice burn on a general road is
The ice plate has uneven thickness and hardness. In addition, there are places with and without ice sheets, and the road surface conditions are various. Further, there may be steps or installed objects on the road. Therefore, even if the height of the wheel 18 is adjusted to adjust the abutting condition of the spike pin 27 to the ice plate before starting the work, the optimum abutting condition is not always maintained. When the ice plate is thin or nonexistent, the road surface is damaged by a high hardness spike pin, cutting blade, or the like in a conventional anti-slip surface forming device. However, in the present embodiment, the winding portion 27a of the spike pin 27 absorbs the external force when a force larger than a predetermined value is applied to the tip end portion of the spike pin, so that the road surface is not damaged even in such a case. , Spike pin 27 or spike roller 1
1 can also be prevented from being damaged.

As described above, the spike roller 1
1 can be switched, and the length of each anti-slip pattern P formed when the spike roller 11 is driven in the reverse direction becomes longer than when the spike roller 11 is driven in the forward direction. Therefore, the rotation direction of the spike roller 11 may be switched according to the road surface condition and the work condition. Further, when the spike roller 11 is driven in the reverse direction, the shavings of the ice are scattered toward the front of the apparatus. Therefore, when the work is performed in a place where it is not suitable, the chip may be driven in the normal direction.

[0021]

As described above, according to the anti-slip surface forming apparatus of the present invention, since the spike pin has a predetermined elasticity, the anti-slip surface is formed on the frozen road surface in response to various road surface conditions. It is possible to prevent damage to the road surface or damage to the spike pin or the spike roller.

According to the structure of claim 2, a predetermined elasticity can be exhibited by the winding portion of the spike pin without manufacturing the spike pin with an expensive material, so that the material cost and the manufacturing cost can be suppressed. .

According to the third aspect of the present invention, the spike pin can be easily and securely attached to the spike roller, and the cost of the spike roller can be reduced and the durability can be improved.

According to the structure of claim 4, since the rotation direction of the spike roller can be switched, it is possible to perform the slip-resistant surface forming work according to the road surface condition and the work condition.
