Description

  The present invention relates to a snow-protection panel elevating device and a method for elevating a snow-protection panel used when attaching and removing a snow-prevention panel of a snow fence that is installed along a road or railway in a snowy region.

The snow protection panels of the snow fences that are installed along the roads or railways in the snowy region are installed only during snowfall, and are removed during the other periods so as not to obstruct the view of the surrounding scenery. The weight of one snow protection panel of the snow fence is about 60kg, and there are problems in the work efficiency and work safety at high places of workers when attaching and removing the snow protection panel, and solve these problems Therefore, some kind of snowproof panel lifting device is used.
Japanese Utility Model Registration No. 3090205 (hereinafter referred to as “Conventional Example 1”) as a conventional snow fence lifting / lowering device for snow fences includes a panel such as a snow guard between pillars erected on both sides of the panel. At the top of both ends of the panel, a small moving pulley is attached, the wire rope is passed to the two moving pulleys, and the wire rope is directed upward via the left and right moving pulleys. The end of the rope is fixed to the upper end of the pillar on one side, and the other is directed downward via a fixed pulley installed on the upper part of the pillar on the other side and wound around a hoisting machine, manually or driven There has been disclosed a panel lifting device which can be lifted or lowered by a device so that the panel can be lifted and lowered.
Japanese Patent No. 2909400 (hereinafter referred to as “conventional example 2”) discloses a lifting device for a snowproof panel in which a snowproof panel of a snowbreak fence is lifted and hung by a crane of a crane truck traveling on a road. .
Utility Model Registration No. 3090205 Japanese Patent No. 2909400

However, in the conventional snow prevention panel raising / lowering device, since the machine elements such as pulleys are exposed in a state where they are not always in operation, the work of raising and lowering the snow prevention panel is performed when installing the snow prevention fence in the snowy season. In many cases, these lifting devices do not function due to rusting of the target elements, and there is a problem that the load of the manual winch becomes large and work cannot be performed efficiently.
Moreover, in the snow-protection panel raising / lowering apparatus of the prior art example 2, since the work vehicle provided with the crane for raising / lowering the snow-protection panel travels on the road when the snow-protection panel is lifted / lowered, the general vehicle cannot travel during the work period. Will occur.

  The present invention solves the above-mentioned problems of the prior art with a simple configuration, and does not obstruct the traveling of a general vehicle on the road during work, and it is possible to efficiently and safely lift and lower the snowproof panel with a small number of workers. An object of the present invention is to provide a snowproof panel lifting device and a lifting method capable of performing the above.

In order to solve the above-mentioned problem, the first invention of the present invention is a device for elevating and lowering a snowproof panel that is detachably mounted between two snowproof fence posts in a snowproof panel elevating device for a snow fence, And a pillar material that can be detachably attached to the front surface of the snow fence post when the snow protection panel is attached and detached , and the pillar material includes an engagement member and a pillar material that are detachably attached to the front surface of the snow fence post. a pulley which is fixed to the upper end, is passed over the pulley, the lifting the snow panel, and a wire rope for unloading hanging, the engaging member is lockable pillar back side snow fences strut upper end an upper engaging member provided on the upper, is composed of a lower engaging member provided on the lockable pillar backside lower the lower snow fences struts, characterized in Rukoto.

  According to the second aspect of the present invention, in the snow protection panel lifting / lowering device of the snow fence according to the first aspect of the invention, the pulley is attached to the upper end portion of the column member and the back side of the column member.

  The third invention is characterized in that, in the snow protection panel lifting / lowering device of the snow fence according to the first or second invention, a wire rope winding / unwinding winch is attached to the front surface side of the pillar material.
