Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to prevention of a slip accident caused by a frozen road surface (ice burn) in a snowfall area.

[0002]

[Prior art]

 The freezing of the road surface that occurs in snowfall areas causes frequent slip accidents and is a serious social problem. Conventionally, the method that has been used to prevent slip accidents is to prevent slippage by using spiked tires.

However, running a vehicle using a spike tire scrapes off asphalt on an unfrozen road surface to generate asphalt dust. In addition, the generated dust mixes with the accumulated snow and accumulates with the snow, and appears on the road shoulders as the snow melts in early spring, and this dust is polluted by the wind and pollutes the atmosphere.

It has been confirmed hygienically and medically that the inhalation of such dust-containing air adversely affects the human body. Therefore, bylaws that prohibit spiked tires have been established in the major local governments in snowy areas, and statless tires have come to be used mainly.

However, by using statless tires, the snow accumulated on the road surface is stomped by the tires of a vehicle or pedestrians, and an unexpected phenomenon of generating slippery ice burns appears. In this way, the braking function of the statless tire is significantly reduced on the road surface formed in the shape of an ice burn.

Therefore, by prohibiting spiked tires, slip accidents such as rear-end collision accidents and contact accidents frequently occur in addition to personal injury accidents. In addition, accident handling and excessive careful driving to fear an accident cause traffic congestion, and today it is taken up as one of the most important issues that local governments must solve.

[0007] In order to solve these problems, attempts have been made to prevent the formation of a frozen road surface (ice burn) by making the road surface road-heated. However, it will take a huge amount of construction cost for several minutes and a considerable amount of maintenance cost is expected, so priority is given to locations with high risk, and it is difficult to implement it on general roads.

[0008] Also, in order to prevent slip accidents on frozen road surfaces (ice burns) such as general roads and slopes, calcium chloride is sprayed or sand is sprinkled, but calcium chloride spray causes salt damage to plants and vehicles. Excuse me.

[0009] The work of sprinkling sand is similar to scattering the source of dust as with the asphalt dust described above. Furthermore, dry sand accumulates on the road shoulders after the snow melts and clogs sewers and rainwater basins. There is a thing.

Since the work of spraying calcium chloride and sprinkling sand is a work in the cold, it is difficult and troublesome to secure human resources. Furthermore, since all the work to remove sand that has accumulated on the shoulders of roads and that has clogged sewers or rainwater basins depends on human resources, local municipalities are often worried about securing transportation means due to the rise in personnel costs and the burden of various costs. It has become a challenge.

[0011]

[Problems to be solved by the device]

 The present invention aims to prevent slip accidents that occur on a frozen road surface (ice burn) in a snowfall area, but at the same time, it does not generate asphalt dust on the road surface that is not frozen and does not generate asphalt dust. It provides maintenance vehicles.

[0012]

[Means for Solving the Problems]

 In the present invention, a cutting blade chain formed with cutting blades is stretched and tied to a cutting sprocket that is configured on the left and right sides of the direction of travel of a cutting vehicle, and this can be rotated forward and backward as desired, thereby freezing road surfaces (ice burns). The purpose is to prevent slip accidents by forming a diamond-shaped lateral groove in) and increasing the friction coefficient between the road surface and tires to enhance the braking function of the traveling vehicle.

Further, by constructing the cutting blade as a flexible structure, it is possible to provide a road surface maintenance vehicle that does not generate asphalt dust by scraping off asphalt on an unfrozen road surface.

[0014]

[Action]

 A diamond-shaped lateral groove is formed on the frozen road surface (ice burn) to enhance the braking function of the traveling vehicle and prevent slip accidents. However, by configuring the cutting blade as a flexible structure, asphalt dust is generated. It provides a new road maintenance vehicle that does not require maintenance.

【Example】

 An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a plan view of the ice burn scratcher according to the present invention, taken along line XX of FIG. Figure 2 is a side view of the Ice Burn Scratcher. FIG. 3 is a side view showing a mounting state of the cutting chain and the cutting blade.

FIG. 4 is a side view showing an operation of forming a lateral groove on a frozen road surface by a cutting blade. FIG. 5 is a plan view showing a vertical groove formed on a frozen road surface by a conventional technique. FIG. 6 is a plan view showing a lateral groove formed on a frozen road surface by the technique of the present invention.

FIG. 1 is a plan view of an ice burner scratcher A according to the present invention. The ice burner scratcher A is equipped on the front or rear of a cutting vehicle and is established as a road surface maintenance vehicle. In the present invention, since the functional explanation of the Ice Burn Scratcher A will be focused, the explanation of the equipment type condition of the road maintenance vehicle will be omitted.

The ice burner scratcher A comprises cutting sprockets SA and SB on the left and right of the pedestal A1 with respect to the traveling direction of the cutting vehicle, and the pedestal A1 is a top plate in which a lifting bracket A3 is formed by a wire rope A2 from a square. Are connected to and form a box condition.

A cutting blade chain SC is stretched and connected to the cutting sprockets SA and SB, and a cutting blade K having a flexible structure is formed on the cutting blade chain SC by a wire fixing bracket K1. In addition, regarding the positional relationship between the cutting sprockets SA and SB, the ability does not change whether it is left or right.

The cutting blade K is formed on the wire fixing bracket K1 by the wire K2, the cutting blade fixing bracket K3, and the blade K4, but it is necessary to obtain the flexibility for hitting the frozen road surface R1.

In order to solve this problem, the wire K 2 which has an appropriate repulsive force and strength and can be obtained at low cost was used as a main material for obtaining flexibility. The advantage of using the wire K2 is that the flexibility of hitting the frozen road surface R1 can be freely controlled by adjusting the length of the wire K2.

Drive sprockets EA and EB are formed on the upper portion of the cutting sprocket SA via a shaft F and are connected by a drive chain EC. Further, a motor M is connected to the drive sprocket EA.

The ice burner scratcher A is built in these and is integrally configured to be installed in a cutting vehicle. The ice burner scratcher A is pulled up by a traction device (not shown) except for the frozen road surface (ice burn) and is separated from the road surface.

The procedure for operating Ice Burn Scratcher A will now be described. When the cutting wheel reaches the icy road surface, the traction device lowers the ice burner scratcher A to the icy road surface, and the weight of the ice burner scratcher A is pressed against the icy road surface R1 and brought into contact therewith.

Since they are brought into contact with each other by their own weight, the shape of the road surface (roughness, inclination, etc.) can always be set horizontally. Further, the wire rope A2 connected to the top plate forming the pedestal A1 and the elevating bracket A3 flexes in a timely manner according to the road surface condition, so that the function is not hindered.

When the motor M is started, the drive sprocket EA starts to rotate and the drive sprocket EB also starts to rotate via the drive chain EC. The rotational movement of the drive sprocket EB is transmitted to the cutting sprocket SA via the shaft F and is rotated.

The rotary motion of the cutting sprocket SA causes the cutting chain SC which is stretched and connected to the cutting sprocket SB to operate in an elliptical shape. A cutting blade K having a flexible structure is formed in the cutting blade chain SC, and as shown in FIG. 4, shaving diamond-shaped lateral grooves R2 and R3 are formed so as to scratch the frozen road surface R1.

The diamond-shaped lateral groove R2 showing the formed geometric pattern becomes as close as possible to the lateral groove R3 as the speed of the cutting vehicle becomes slower, and the friction coefficient between the road surface and the tire becomes large. It gets shorter.

Up to now, many attempts have been made to scrape the frozen road surface R1 to increase the coefficient of friction between the road surface and the tire by forming a groove, but since it is applied as a force for cutting the advancing force of a cutting vehicle. The formed groove is formed like the vertical groove R5 as shown in FIG.

A groove formed like the vertical groove R5 can prevent the vehicle from skidding, but cannot shorten the braking distance.

[0031]

[Effect of device]

 Statless tires are used because it is possible to easily form lateral grooves on a frozen road surface by the cutting chain that is stretched and tied on the cutting sprockets provided on the left and right of the Ice Burn Scratcher A, and the cutting blade formed on the cutting chain. The braking ability of the running vehicle on the frozen road surface was greatly enhanced.

Therefore, slip accidents that occur on a frozen road surface (ice burn) can be reduced, traffic congestion that local municipalities have been troubled with can be solved, and at the same time, asphalt on an unfrozen road surface can be scraped to remove asphalt dust or sand. Dust can also reduce air pollution that has a negative impact on the human body.

Further, since it is possible to reduce the spraying of calcium chloride and sand as much as possible, it is possible to prevent the occurrence of salt damage and dust, remove the trouble and trouble of cold work, and significantly reduce the dust treatment after snow melting. Therefore, road maintenance vehicles that can reduce personnel expenses and other expenses can be widely provided to the society.
