Description

[Detailed description of the invention] As a main business, it's easy to use! The present invention relates to a snow eaves disposal method for cutting off snow eaves formed on stone walls along roads, snow sheds, and the like.

Usually, protruding lumps of snow called ``snow eaves'' form on stone walls, fences, and snow sheds along roads in areas with a lot of snow.

Fig. 1 shows an example of a snow eave (A) formed on a stone wall along a road, and Fig. 2 shows an example of a snow eave (A) formed on a snow shed. As the days pass, this snow canopy (A) gradually becomes larger and becomes unable to support itself and falls onto the road, obstructing traffic, falling onto cars, or even driving cars into valleys. In order to eliminate this danger, to prevent the snow eaves (A) from growing too large, the fallen snow was manually removed at the appropriate time, and the fallen snow was removed using snowplows. The work required a lot of effort and time, and was extremely dangerous as it involved climbing on top of the snow eaves (A) and using a shovel to remove it.

This invention is a method of cutting and removing snow eaves by moving the vehicle while drilling holes in the snow eaves using high-pressure water from a high-pressure water generator mounted on a vehicle.This snow eaves treatment method solves the above-mentioned conventional problems. It is something.

Hereinafter, a third snow eave treatment vehicle for carrying out the method of this invention will be described.
The explanation will be as follows with reference to the figures and FIG.

In Fig. 3, (1) is the vehicle body, (2) and (3) are the water tank and high pressure water generation pump unit that constitute the high pressure water generator mounted on the vehicle body (1), and (4) is the water tank. The turntable (5) installed on the top of the tank (2) consists of two booms: an outer boom (5a) and an inner boom (5b).
) is pivotally connected to the support frame (6) provided on the turntable (4) so that the root part of the turntable (
4) The raising and lowering operation is performed by the raising and lowering cylinder (7) provided between the (8) is a water emitting nozzle attached to the tip of the boom (5b) inside the boom (5) so that it can swing vertically and horizontally, and the boom (5) can be raised and lowered by remote control from the driver's seat.
It can be rotated, expanded and contracted and placed in any position in the air,
You can freely select the direction of water discharge by swinging it up, down, left or right to match the slope of the stone wall, etc. on which the snow canopy is placed.

The above-mentioned snow eave treatment vehicle pressurizes water sucked out from a water tank (2) with a high-pressure water generation pump unit (3), and the pressurized high-pressure water is passed from the pump unit (3) to a turntable (
4) to the root of the boom (5), and then along the boom (5) to the water ejection nozzle (8) at the tip of the boom (5), and from the water ejection nozzle (8) high pressure water is sent. It is configured to spray water.

Next, a description will be given of snow eave processing work using the snow eave processing vehicle.

First, as shown in Figure 4, the snow eaves processing vehicle is stopped on the road so that its direction of movement is aligned with the stone wall whose snow eaves (A) is to be processed, and then the boom (5) is raised, swiveled, extended and contracted to remove water. For example, the water emitting nozzle (8) is disposed close to the top of the snow eave (A), and the water emitting nozzle (8) is swung vertically and horizontally to align the direction of water discharge with the slope on which the snow eave exists (fourth Point it in the direction shown by the dotted arrow in the figure.Next, the high-pressure water pressurized by the high-pressure water generation pump unit (3) is sprayed from the water ejection nozzle (8), and the sprayed high-pressure water is used to spray the snow eaves ( Drill a transparent hole in A) from above to below.In this state, if you move the car body (1) slowly along the stone wall, the snow will fall one after another as the car body (1) moves. The snow canopy (A) is removed and the snow canopy (A) is cut off with a long series of holes, and then the snow chunks fall onto the road and the snow canopy (A) is removed.

In the above embodiment, the boom (5) is described as being of a straight type, but it may be of either a straight type or a refracting type, as long as the water emitting nozzle (8) can be placed in a high place.

As explained above, this invention uses high-pressure water from a high-pressure water generator mounted on the vehicle to cut and remove the snow eaves by moving the vehicle while drilling holes in the snow eaves. Snow cornices can be treated easily and quickly, and therefore, the treatment work is carried out very efficiently, the labor required for this is eliminated, the work is not dangerous, and the water ejection nozzle is High-pressure water jets can be used as a substitute for force and tar, making it possible to remove snow eaves without worrying about the presence of obstacles such as stone walls hidden inside snow eaves.
