SOLUTION: In the strut erected in a line of a cableway for supporting a cable line, the snow melting device is fit in a side face of the strut so as to face an interior, an electric cable is laid along the line of the cableway, and electricity is fed to the snow melting device from the electric cable.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a column with a snow-melting device in which a snow-melting device for melting snow around the column is mounted on a column for supporting a cable in a cableway.

[0002]

2. Description of the Related Art A cableway stretches and circulates a rope between pulleys provided at a stop at both ends, and transports a person or an object by suspending a carriage on the rope. It is well known that it is used as a transport system in mountainous areas and is often used as a ski lift or a gondola lift.

[0003] In a track of a cableway, a plurality of pillars are erected to elevate the ropes, and the ropes are supported by a rope receiving device provided on the pillars. As described above, since the cableway is often used for applications such as ski lifts, the strut is often buried in snow to a considerable height from the ground surface in the snowy season in winter. In addition, there are facilities on the cableway that is provided in heavy snowfall areas, etc., where the entire support is buried in the snow in winter and the operation is resumed by removing snow during the thaw season in spring.

[0004]

In general, the support of the cableway is generally erected on a slope, and when the support is buried in snow as described above, the snow pressure is applied to the support from above the slope. It will work downwards, i.e. substantially from the side of the strut. The pillar has the original function of supporting the rope as described above, and is mainly for supporting the load in the direction of gravity. Thus, the load from the lateral direction is applied by the snow pressure. It is not preferable.

Inspection of these columns requires a lot of labor for snow removal. Particularly, in the case of a cableway in which the entire column is buried in the snow, much labor is required.

SUMMARY OF THE INVENTION The present invention has been made in view of such circumstances, and it is possible to eliminate snow pressure applied to a support from a lateral direction and to reduce labor for removing snow around the support. The purpose is to provide a cableway support that can be used.

[0007]

SUMMARY OF THE INVENTION In accordance with this object, the present invention is directed to a column for supporting a cable standing upright in a cableway, the side of the column being directed toward the inside of the column. And fitted a snow melting device, laid electric wires along the cableway line,
The electric wire is adapted to supply electricity to the snow melting apparatus, and is configured as a column with a snow melting apparatus for a cableway.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 is a longitudinal sectional view showing a cableway line. In the figure, the stop 1 at the foot of the mountain and the stop 2 at the summit
Are provided with pulleys 5a and 5b, respectively, and the rope 3 is endlessly circulated and looped between the pulleys 5a and 5b. The cable 3 is supported by columns 4, 4, ... standing upright on a slope in the cableway.

FIG. 2 is a front view of a pillar with a snow melting device according to the present invention. The strut 4 is erected on a concrete foundation 6 formed on the ground, and a receiving ring 5 pivotally attached to the head of the strut 4.
5 supports the rope 3. The strut body member 4a
It is made of a round steel pipe or a square steel pipe, and the height of the column 4 is usually about 6 m to about 12 m.

At a height of about 1 m to about 2 m from the lower end of the pillar 4, a snow melting device 10 is fitted on the side surface of the pillar main body member 4a, and a power supply box 11 is provided below the snow melting device 10. It is fixed. On the other hand, the electric wire 12 is buried in the ground along the cableway, and each of the columns 4, 4,
The snow melting devices 10, 10,...
Are supplied from the power supply boxes 11, 11,....

Next, details of a mounting portion of the snow melting apparatus 10 will be described with reference to FIG. FIG. 1 is a sectional view of a mounting portion of the snow melting device 10. A hollow pipe member 7 penetrates through the side surface of the column main body member 4a, and projects outward from the column main body member 4a and is fusion-welded. A flange member 8 is fusion-welded to an end portion of the pipe member 7. I have. The snow melting device 10 is inserted into the mounting portion formed in this way, and is fixed to the flange member 8 with bolts 9. In the snow melting apparatus 10, a heat generating portion 10a uses an elongated electric heater, and the capacity of the electric heater is about 1.5 kW to 3 kW economically when the height of the column 4 is about 10 m. Is preferred.

The snow melting device 10 attached to the column 4 is always energized during an arbitrary period during which snow falls. By doing so, the heat generated by the snow melting device 10 is constantly transmitted to the column body 4a,
Since the snow falling around the column 4 is constantly melted, it is possible to prevent the snow from being closely attached to the column 4 and accumulating snow.

[0013]

The strut with the snow-melting device of the present invention is constructed as described above. When the snow falls, the snow around the strut is constantly melted and snow-covered, so that a space is formed around the strut and the snow cover. Therefore, it is possible to prevent the snow pressure due to the snow from acting on the support.

In addition, since the space is formed around the column in this manner, the column can be easily inspected even during snowfall, and furthermore, most of the column is buried in winter. In the cableway, the strut is prevented from being damaged, and the snow removal is facilitated when driving is resumed.
