Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a snow removal device for a median strip used on temporary two-lane roads such as expressways.

[Conventional technology and technical issues to be solved] Today, as we enter the era of full-scale automobiles, all efforts are being made to develop national expressways and expressways, but due to the sudden increase in demand for roads, In order to meet this growth, it is sometimes unavoidable to open some unfinished national expressways. At this time, some unfinished sections will be tentatively
It is often opened as a lane road for two-way traffic.

These temporary two-lane roads often have concrete curbs and rubber balls as median strips. However, in winter, snow that has accumulated around these concrete curbs and rubber balls that protrude onto the road cannot be removed using conventional plows because they get caught on the concrete curbs and rubber balls. It had been left piled up.

As a result, the area around the center of the road is not cleared of snow, and the remaining snow around the center of the road can collapse onto the driving lanes or block the reflection of lights from the reflectors installed in the median strip, creating a dangerous situation. This made the two-way traffic section even more dangerous.

The present invention was made in view of the above-mentioned problems in snow removal from the median strip of a temporary two-lane road. The technical challenge is to provide such information.

[Means adopted to solve the problem]

The means adopted by the present inventor to solve the above problem will be explained below with reference to the accompanying drawings.

That is, in order to remove snow from the foot of a concrete curb, a snow removal plow 2 having a urethane edge 2a on the right edge end is supported by a carrier 1 and placed in front of a snow removal vehicle M, and rotates freely to cut down one wall. The cutting blade 3 is rotatably supported on a bearing 3b attached to one side of the carrier 1 so as to be vertically movable, and the sweep edge 4 is inverted to the same side as the rotating cutting blade 3 of the carrier 1. An elastic body 5 that is protruded so that it can touch the ground and supports the sweep edge 4 for snow removal work reverses the sweep edge 4 when the sweep edge 4 collides with an obstacle on the ground.
When the driver passes the obstacle, the sweep edge 4 is returned to the snow removal position, and the guide wheels 6a, 6a, 6b, 6
b is placed on the carrier 1, and the drive position of the device is determined by contacting the concrete curb with the wheels.By adopting this method, the center of the road can be cleared of snow even if there are concrete curbs or rubber poles. The company provided snow removal equipment for separation zones.

[Example] The present invention will be described below based on an example shown in the accompanying drawings.

A single-stream snow removal plow 2 is held in front of a carrier 1 attached to the front of a snow removal vehicle M. A urethane edge 2a is attached to the right edge of the snow removal plow 2,
Even if the right edge of the snow removal plow 2 rubs against the concrete curb, the snow removal plow 2 will not be damaged (it is possible to remove snow from the foot of the concrete curb.Furthermore,
A bracket) 3a is attached to the right side of the carrier 1 via a bar 18.
A four-blade waterwheel-shaped rotary cutting blade 3 is supported by a bearing 3b attached to the bearing 3b. The rotary cutting blade 3 can be vertically moved by rotating an adjustment screw 30 attached to the bracket 3a, and can be set to a desired height to avoid a concrete curb. While rotating in contact with one wall formed by the snow removal work of the snow removal plow 2, the blade of the long wing provides a cutting part in one wall, thereby having the effect of cutting down one wall and making it easier to melt the snow. Furthermore, when the rotary cutting blade 3 collides with the rubber pole, the blade rotates to avoid this collision. Now, career 1.
A sweep edge 4 is provided by an elastic body 5 behind the rotary cutting face II3 of the bar 1a provided on the right side of the bar 1a. The sweep edge 4 is in contact with the ground and removes snow when the snow removal vehicle M runs, but when it collides with a ground obstacle such as a concrete curb, it is reversed by the action of an elastic body 5 and returns to its original position after passing over the concrete curb. By repeating this reversing motion, snow can be removed between concrete curbs. Also, when the sweep edge 4 collides with the rubber ball, it is avoided in the same way (see FIGS. 1, 2, and 3).

At the rear end of the carrier 1, slide rails Ib-1b are arranged vertically in parallel. These slide rails 1b and 1b are slide guides 1c and 1b arranged on the lifting bracket 1d.
1c, 1c, and 1c, and the bottom side of the fluid pressure cylinder 1e is fixed to the bracket Hd. A shaft stopper 1g having a protrusion 1f is fixed on the rod side of the fluid pressure cylinder 1e, and slides left and right as the fluid pressure cylinder 1e expands and contracts.

Shafts 1h, 1h are attached to this shaft stopper 1g, and a spring holder 11 is further fixed to the shafts 1h, 1h. Spring holder 11
and the frame 1j of the carrier 1 is a buffer spring l.
k・1k are arranged. As described above, when the fluid pressure cylinder 1e extends, the protrusion 1f provided on the shaft stopper 1g pushes the frame 1j of the carrier 1 to the left, and the entire snow removal device moves to the left. Further, when the fluid pressure cylinder 1e retracts, the shaft stopper 1g moves to the right, the buffer springs 1k expand, and the entire snow removal device extends to the right. In addition, since the lifting bracket ld is attached to the lifting link 11 located in front of the snow removal vehicle M, the carrier 1 is located in front of the snow removal vehicle M, and the carrier 1, the snow removal plow 2, the rotary cutting blade 3, The sweep edge 4 can be moved horizontally to the working position and forwarding position, the width of the vehicle can be reduced during forwarding, and the snow removal plow 2, rotary cutting blade 3, and sweep edge 4 can be set to the most convenient position for work. . Furthermore, if the buffer springs 1k and 1k are provided, their buffering force can prevent the snow removal plow from being damaged even if it receives an impact from the side of the snow removal plow (see FIGS. 2 and 4).

Furthermore, a guide wheel 6 is attached to the bar 1a on the right side of the carrier.
a, 6a, 6b, and 6b are also provided swingably.

The guide wheels 6a, 6a are vertically installed below the bar 1a, and the guide wheels 6b, 6b are installed protrudingly from the right side surface of the bar 18.

When the horizontal angles of the guide wheels 6b and 6b are set appropriately and the snow removal vehicle M is run so as to roll along the edge of a concrete curb, the snow removal plow 2, rotary cutoff blade 3, and sweep edge 4 move along the road running part and the center. It allows you to reach the most suitable position for clearing snow in the vicinity and prevents damage to the entire device. The guide wheels 6a, 6a run on the ground to support and assist the carrier 1 at a predetermined height (see FIG. 5).

Although the present embodiment is configured as described above, the present invention is not limited to the above embodiment, and it is also possible to increase the number of rotary cutting blades.

[Effects of the present invention]

As explained above with reference to the embodiments, the snow removal device for the median strip of the present invention promotes snow melting by allowing the freely rotating rotary cutting blade to cut down one wall formed by the snow removal plow, and later By running the vehicle again, the snow that has fallen on the road surface can be removed, and therefore,
Snow remaining on the median strip in the center of the road can be removed.

This will prevent the snow that has accumulated on the center section 8111 from collapsing onto the road and becoming a hindrance to traffic, and will also prevent the snow from melting during the day and freezing on the road surface at night, creating a dangerous condition for traffic. Moreover, since the rotary cutting blade can be vertically moved to set an appropriate position, concrete curb stones can be avoided, and rubber balls can also be avoided by rotating the blade. In addition, snow is removed from the sides of concrete curbs and rubber balls using sweep edges that avoid flipping using elastic bodies, which prevents remaining snow from forming near median strips using conventional snow removal technology. This will ensure safe driving on roads such as roads.

As described above, the snow removal device for the median strip of the present invention has high industrial utility value.
