Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a snow removal device, and more specifically, to a snow removal device that scoops snow accumulated on a roof and makes it easier to fall.

[Prior Art] Snow that has accumulated on the roof has the risk of crushing the house with its weight, so in regions with heavy snowfall, snow that has accumulated on the roof is removed.

This snow removal work is dangerous because it is performed on roofs, which are high and sloped with poor footing.

In order to reduce the load on the roof, this work must be done, and there are two ways to do it: manually or by installing a sprinkler system to melt the snow.

[Problems to be solved by the invention] Manual snowfall requires many people to climb onto the roof using tools such as a scoop, which is extremely dangerous as described above. In addition, the method of melting snow by sprinkling water requires a large initial investment and has a low operating rate throughout the year, while using hot water increases running costs even further. The purpose of this invention is to provide a device that can remove snow safely and inexpensively with less manpower in order to eliminate the above-mentioned drawbacks of the conventional method.

[Means for Solving the Problems] In order to achieve the above object, the snow removal device of this invention has a lower sled 15 attached to the lower frame member 12 constituting the structurally reinforced rectangular cylindrical frame 10. The frame body 10
An upper sled 1 for preventing crawling into the upper frame member 11 constituting the frame body 10 on at least one opening side of the upper sled 1
6, and a cable attachment fitting 17 on the one opening side.
The snow scooping device 1 is composed of a snow scooper 1 to which a snow scooper 1 is attached, and a roof horse 2 to which a fixed pulley 22 for guiding the direction of the cable 3 is attached.

[Function] The snow removal device of this invention removes snow 5 accumulated on the roof.
First, the roof horse 2 is placed on the roof ridge 42 and placed on the snow scooping tool 1 on one side of the eaves 43, and the cable 3 with one end fixed to the snow scooping tool is attached to the fixed pulley 22 of the roof horse 2. By pulling the cable 3, the snow scooping tool 1 is pulled up on the roof 40, thereby scooping up the accumulated snow 5 and letting it fall from the roof, and from the eave side. Once the snow has been pulled up to the roof ridge, the snow on the roof can be removed safely and with less manpower by shifting the position by the width of the snow scooper and repeating the same process.

[Example] The snow removing device of this invention is composed of a snow scooping tool 1 and a roof horse 2, and the snow scooping tool 1 is made of a lightweight steel plate or aluminum plate, as shown in FIGS. 1 to 3. The upper and lower frame members 11 and 12 made of metal and the side frame members 13 constitute a cylindrical frame 10 with a square cross section, and the upper frame member 11 and the side frame members 13 are arranged inside.
A pair of reinforcing members 14 are installed in a V-shape between the ridge of the frame member 12 and the center of the lower frame member 12 to provide structural reinforcement, and one end of both ends of the lower frame member 12 in the width direction is warped. A pair of lower sleds 15 that are longer than the frame members by the length of the warped portion are fixed, and the upper sled 16 with the warp formed on one end of the upper frame member 11 is fixed, and the upper part on the side where the upper sleds are attached is fixed. Cable 3 on frame material 11
It consists of a structure in which a pair of cable attachment fittings 17 are attached. As shown in FIGS. 4 to 6, the roof horse 2 has a fixed pulley 22 at the center of the ridge of a saddle body 20 which is formed by bending a plate member 21 into a V-shape according to the slope of the roof.
The structure is such that a non-slip material 23 is attached to the lower side of each of the plate-like members 21.

The snow removal device of this invention is constructed as described above, and snow removal work using this device will be described below.

As shown in FIGS. 4 and 5, a roof 40 made of roofing material 41 such as galvanized iron or straw for a house 4
When the amount of snow completely piled up on the roof exceeds a certain amount that does not exceed the load-bearing limit, the roof horse 2 is manually placed on the roof ridge 42, and the snow scooping tool 1 is placed on one eave 43 side. cable 3 attached to the snow scooper 1
is hung on the fixed pulley 22 and pulled down to the other eave 44 side, and if this cable 3 is pulled in the direction of the arrow with a winch or the like (not shown), depending on the condition and material of the roofing materials, the roofing materials overlap and become stepped. Even if the lower sled 15 is curved at the tip, it will not get caught, and the upper sled 16 will prevent the cylindrical frame 10 from sinking into the snow 5 and pull it up to the roof ridge 42 side. The snow 5 on the roof is scooped up, and the snow swallowed from one opening 18 is removed under the eaves through a flexible shed 6 shown by imaginary lines attached to the other opening 19 side.

In regions with heavy snowfall, the roof horses 2 can be used directly or mounted on the roof ridge 42 as shown in FIG. 6, or by attaching a large number of them in advance, without having to move them as will be described later.

Once you have finished clearing from the eaves to the roof ridge, move the roofing horse 2 by the width of the snow removal tool 1 and start falling snow from the eaves side again in the same way, and when one side of the roof is finished, the other By doing this on one side, you can remove snow from your roof in a short period of time without any danger or fatigue.

Note that instead of the fixed pulley 2, a known cable guide member for changing the direction of the cable 3 can be used.

[Effects of the invention] As described above, this invention has the lower sled 15 attached to the lower frame member 12 constituting the structurally reinforced rectangular cylindrical frame 10, and the lower sled 15 attached to the lower frame member 12 on at least one opening side of the frame member 10. A snow scooper 1 is provided with an upper sled 16 for preventing the user from climbing into the upper member frame 11 constituting the snow scooper 1, and a cable attachment fitting 17 is attached to the one opening side, and a snow scooper 1 for guiding the direction of the cable 3. Since it consists of a roof horse 2 with a fixed pulley 22 attached, only one person needs to climb onto the roof, which eliminates great fatigue and danger and allows snow to be removed efficiently.It can also be used as a sled. It has the effect of being able to.
