Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for removing snow accumulated on an edge of a road in a short work section when performing snow removal work on a road, and a snow melting vehicle used for removing snow.
[0002]
[Prior art]
For example, as shown in FIG. 9, the snow S removed from the traveling lane 31 and the overtaking lane 32 by the snowplowing work is once removed from the shoulder of the road. And accumulated in the roadside belt 33. This snow blocks the emergency vehicle traffic zone (roadside zone) of the road. Conventionally, the accumulated snow S is removed by loading the disturbing snow on the truck 51 and carrying it away. For example, the above-described snow is loaded onto a truck 51 at a loading place 53 by a tire shovel (shovel loader) 34. When the truck 51 is fully loaded, the truck 51 passes through the highway and carries snow toward a snow disposal site provided outside the highway. On the other hand, the next truck 52 that has been waiting moves to the snow loading place 53 and loads the snow S again on the truck 52. Such work is repeated one after another. By removing the snow S in this way, normal traffic on the road can be recovered. Also, the method as described above has the convenience that it can be carried out anywhere because it can go to the place where the snow S is accumulated and remove the snow there. In FIG. 9, reference numeral 55 denotes a marker installed on the road in order to clearly indicate the work section 54.
[0003]
[Problems to be solved by the invention]
However, the conventional method described above has a problem in that it requires high transportation costs because all the snow must be carried by a truck. In order to remove the above-mentioned snow in a short time, it is necessary to carry the snow on the truck one after another without interruption, and for that purpose, a large number of trucks 52 must be kept waiting as shown in the figure. Then, the waiting trucks 52 lined up side by side block the traveling lane 31 over a long section 54, and there is a problem that hinders traffic.
Also, on the main roads of up and down lanes in urban areas, if there are many snow carrying trucks occupying one lane over a long section, there will be a problem of causing heavy traffic congestion.
[0004]
The method for removing snow on the road of the present invention is provided to solve the problems of the prior art.
The first purpose is to remove snow on the road so that normal traffic on the road can be restored.
The second purpose is to be able to remove snow freely anywhere.
The third object is to enable the removal of the snow without the need for transportation costs.

[0010]
Next, the heating means D is configured to heat the hot water in the tank C, and is constituted by members indicated by reference numerals 10 to 16. Reference numeral 10 denotes a burner for generating heat for heating, and an oil burner is exemplified, but a gas burner or other heat generating means may be used. For example, two burners 10 cooked 20 to 50 liters per hour are used. 11 is a combustion cylinder, and the inside is a combustion chamber of the burner 10, and the peripheral wall transfers heat from the high-temperature combustion gas generated by combustion to the water in the tank C (the combustion gas and the water in the tank C). Heat transfer wall). The heat transfer pipes 12 and 14 guide the combustion gas for discharge and cause heat transfer from the combustion gas to the water in the tank C in the process, and 13 connects the heat transfer pipes 12 and 14 to each other. In addition, a connecting tube for transferring heat from the combustion gas to the water in the tank C, 15 is a collecting tube for collecting the combustion gas from the plurality of heat transfer pipes 14, and 16 is a discharge tube for discharging the combustion gas. Each cylinder is shown.
[0011]
Next, the agitating means E is for agitating hot water, agitating warm water and snow, breaking a lump of snow, etc. in the tank C. The agitator 18 provided in the tank C and its drive In order to carry out, it comprises the drive mechanism 19 provided outside the tank C. As can be understood from FIGS. 2, 3, 4, and 6, the agitator 18 is exemplified by a structure in which a large number of agitating blades 21 are attached around a rotating shaft 20 having a lateral axis. The rotary shaft 20 has a barrel 20a formed to have a large diameter for mounting the stirring blade 21 and both ends thereof for supporting it (the right end side in FIGS. 2 and 3 is behind the heating means D). It is comprised from the thin pivoted part 20b connected to. The stirring blade 21 is attached in a twisted state with respect to the rotation direction of the stirring member 18 as shown in FIG. Further, the twisting direction is reversed between the one side 18a and the other side 18b with the central portion 18c of the stirring member 18 as a boundary. Reference numeral 22 denotes a bearing for rotatably supporting the agitator 18 and supports the pivoted portion 20b. Reference numeral 23 denotes a seal member for preventing water leakage at a portion where the member 20b penetrates the tank C. Next, the drive mechanism 19 has a well-known configuration for rotationally driving the agitator 18, and includes a geared motor 25, sprockets 26 and 27, and a chain 28. The rotation speed of the stirring member 18 by the drive mechanism 19 is, for example, about 7 to 63 rotations per minute. Reference numeral 29 denotes a control panel for controlling the operation of the burner 10 and the geared motor 25.
[0012]
The snow removal on the road performed using the snow melting wheel Y having the above configuration will be described. First, water is supplied to the tank C (for example, about 2 m ^{3 in} the case of the apparatus of the above size), and the truck B is run to go to the site as shown in FIG. In this case, a means for putting snow into the tank C, for example, a tire excavator 34, may be put together. In addition, it is good to operate the heating means D and to heat the water in the tank C while traveling to the site. The hot water may be stored in the tank C in advance and then may be started, or the heating may be performed after arrival at the site. The heating of the water in the tank C by the heating means D is as follows. When the burner 10 is burned, high-temperature combustion gas is generated by combustion in the combustion cylinder 11, and the heat of the combustion gas is transmitted to the surrounding water through the peripheral wall of the combustion cylinder 11. The generated combustion gas then passes through the heat transfer pipe 12, the connecting cylinder 13, and the heat transfer pipe 14 in this order. Even in this process, the heat of the combustion gas is transmitted to the surrounding water through the peripheral walls of these members. As described above, the heat of the combustion gas is transferred to the water, so that the temperature of the combustion gas gradually decreases, and the low-temperature combustion gas is discharged from the exhaust cylinder 16 through the collecting cylinder 15 as exhaust gas. In the process in which the combustion gas passes as described above, the water in the tank C receives heat as described above, and the temperature gradually rises to become hot water. In the case of heating the water, the water in the tank C may be agitated by rotating the agitator 18 by the drive mechanism 19 in the agitation means E.
[0013]
Next, at the site, the snowmelt vehicle Y is stopped near the snow S accumulated along the edge of the road 30 as shown in FIG. Then, the snow S is removed using the snow melting device A. In FIG. 8, reference numeral 30 denotes, for example, one of the lanes on the highway that is up or down, 31 denotes a traveling lane, 32 denotes an overtaking lane, and 33 denotes a roadside zone. The removal of snow S is as follows. In the snow melting apparatus A, the heating means D is operated to heat the water in the tank C (which is hot water at this time). Further, the stirring means E is operated, and the stirring body 18 is rotated, for example, in the direction of arrow 36 in FIG. In this state, the accumulated snow S is thrown into the tank C from, for example, the inlet C ′ above it by the tire excavator 34. The charging is preferably performed with the space between the left and right heat transfer pipes 14 as shown in the range indicated by reference numeral 35 in FIG. The introduced snow S receives heat from the hot water W in the tank C and is melted to become water.
[0014]
In the case of melting the snow S in the tank C, the snow S is rapidly melted by the following actions (1) to (5). (1) In the tank C, the hot water W in the vicinity 37 of the snow S is used to melt the snow S and the temperature is lowered. However, since the warm water W in the tank C is agitated by the rotation of the agitator 18, the hot water having a high temperature is supplied to the portion 37 again. Therefore, the snow S is melted quickly. (2) Even if the snow in the tank C floats on the warm water W, the snow is mixed with the warm water W by the movement of the warm water W by the rotating stirring body 18. As a result, the hot water W having a high temperature goes around the snow, and the snow is melted quickly. (3) The snow S that is thrown into the tank C and floats on the hot water W is swept into the hot water W one after another by the numerous blades 21 of the rotating stirring body 18. As a result, the stirring of the snow S and the hot water W is promoted, and the snow is melted quickly. (4) Even if the snow S introduced into the tank C is a large lump as indicated by reference numeral 38 in FIG. 6, the snow is turned into a large number of small lumps 39 by a large number of blades 21 of the rotating stirring body 18. Cut down. Accordingly, the hot water W enters between the pieces of snow S of the small blocks 39 that have been cut. As a result, the contact area between the snow and the hot water is increased, and the snow S is rapidly melted. (5) Even if the amount of snow S put into the tank C is large and the snow S is piled up as indicated by reference numeral 40 in FIGS. The snow S which becomes the pile 40 by 21 is cut down in order from the lower part. Then, the cut snow is scraped into the warm water W by the blades 21. As a result, the snow melts quickly.
[0015]
When the amount of water in the tank C increases due to the melting of the snow S in the tank C, excess water is discharged by overflow from the overflow port 9. You may carry out by the waste_water | drain from the drain port 8. FIG. The discharged water is discharged out of the road 30. For example, it flows in a drain at the edge of the road.
[0016]
If the snow S accumulated on the road 30 disappears due to the continuation of the above operation, the snow melting wheel Y and the tire excavator 34 are removed to complete the snow S removal work, and the roadside belt 33 is opened. The
[0017]
Next, an example of the snow processing capacity of the snow melting vehicle Y is 200 m ³ per day, for example. Therefore, for example, if the amount of snow removal per day at Nagoya High Speed in the Nagoya area is, for example, 1000 m ³ , a total of 200 trucks are required to load the entire amount on a 10-ton truck by 5 m ³ . However, according to the snow melting vehicle Y, snow for 40 trucks per vehicle can be melted and removed, so that only 5 snow melting vehicles Y need be introduced. This has the great effect of eliminating the congestion of roads (round-trip highways and general roads from the place where snow is removed to the place where snow is discarded) due to the passage of many trucks for transportation. This has a great effect on eliminating the need for trucking.
[0018]
Next, in the case of stirring the stirrer 18 in the tank C, a number of the stirring blades 21 provided around the rotating shaft 20 are twisted as described above. As a result, the snow S in the tank C receives a force in the directions of the arrows 41a and 41b parallel to the axial direction of the rotary shaft 20 in FIG. 6, or receives a force in the directions of the arrows 42a and 42b. Accordingly, the direction of rotation of the stirring member 18 by the drive device 19 can be changed forward and backward, and the snow S in the tank C is moved largely in the lateral direction of the arrows 41a and 41b or moved in the lateral direction of the arrows 42a and 42b. Then, the melting of the snow in the tank may be accelerated.
[0019]
【The invention's effect】
As described above, in the method of the present invention, when it is desired to remove the snow S accumulated on the edge of the road 30, the snow S is put in the tank C of the snowmelt wheel Y and melted to make water, which is outside the road. The snow S can be removed from the road and the normal traffic can be restored.
Moreover, since the movable snow melting wheel Y can be sent to any place where the snow S to be removed is present, there is a convenience that the work for removing the snow S can be performed anywhere.
Further, the removal of the snow S is performed by melting and discharging the snow S as described above at the site where the snow S is accumulated. This has the economic effect of eliminating the need for transportation costs, and it is sufficient if there is only a means for putting snow S into the snowmelt vehicle Y and the tank C in the snowmelt vehicle Y, and a large number of trucks for transportation are queued on the road. Therefore, there is an effect that the obstruction section 56 for traffic can be shortened very much.
Further, in the snow melting wheel Y of the present invention, when the snow S is melted, the snow S can be melted by putting it in the hot water W. Therefore, the snow S can be melted quickly, and the snow S in the field can be melted. It is very suitable for use for removal.
Moreover, since the hot water W having a high temperature can be increased in contact with the snow S by the stirring of the hot water W by the stirring means E, there is a feature that the melting of the snow S can be speeded up. This allows the snow S on the road to be introduced and melted one after another, and as a result, the removal of the snow S from the road can be completed in a short time, thereby speeding up normal traffic recovery. There is an effect that can be done.
