Description

It is known to construct air overhead roads with one carrying cable, made, for example, in the form of fixedly fixed at the end points at different heights of the wire, along which the cargo carriages move under the action of gravity. Such cableways, being simple to implement, can be used with advantage, for example, for launching firewood, charcoal in bags and short assortments of a whole forest of mountain slopes, along which none of the other means of transport is feasible due to, for example, unprofitability rugged terrain, etc. The weak point of such roads, however, are intermediate support points supporting the carrying cable, as rocking shoulder-blades, which are usually used in cable-suspended roads, adyvaets track line, have the disadvantage that for changing from one another on the bearing side load carriage must overcome the difference in height between the tangents to baschma; and free hanging cable. In cable-suspended roads using a cable, overcoming this difference in height is accomplished with the help of this latter, but on airways with only one track.

the cable on which the freight trolley moves under the force of gravity; overcoming this height difference is possible only due to the live force of moving trolleys, which manpower under certain conditions may not be enough, and in this case there is no lock between the supports; in other conditions, the living force will develop the speed of movement of the trolley and then last, having met some points on its way (at the point of crossing through the bagmak), will break the track rope.

The present invention aims at eliminating this disadvantage, for which the track cable at each intermediate support is freely suspended from below to the ends of the long rocker swinging on the support. By using this rocker, it is achieved, firstly, that within the intermediate support in front of the moving trolley a reduced portion of the track cable is constantly formed, as a result of which the trolley continues its movement along the slope under the action of gravity, and secondly, that the points in the way and the car, even in the presence of significant speed, quite satisfactorily passes through the support. In the schematic drawing of FIG. 1 shows an air-way with the use of the proposed rocker arms on intermediate supports, side view; FIG. 2-position of the support rocker at the approach of the cargo car to the support-side view; FIG. 3-position of the support rocker with the passage of the trolley on the other side - a side view of the support; FIG. 4 - intermediate support side view; FIG. 5 - the same front view; FIG. b-trolley front view; FIG. 7 - the same side view; FIG. 8 and 9 - version of the cargo truck.

The track cable, as such, can be applied, for example, wire /, is fixed at the top of the track, for example, to tree 2, and supported by paired intermediate supports made up of two tripods formed by poles 3; bound, for example, by a ring 4 fitted on top; the tops of the tripods support the crossmember 5, on which the rocker 6 is laid. The clamps 7 are attached to the ends of this rocker arm, to which the track cable 7 is freely suspended. 3 The lower point of the path is connected to a tension device, for example, a collar S. in this way, trolleys are started up, which can be performed, for example, either in the form of a cramp / O attached to the running roller 9, to which the load is suspended

(Fig. b and 7), or in the form of the same bracket attached to the bar //, fitted with a groove / 2, put on the track cable (Fig. 8 and 9). When a carriage moving along an inclined track cable approaches an intermediate support, the rocker arm 6 turns towards the cart, lowering the track cable, as a result of which the cart passes freely through collar 7 (Fig. 2). Upon further movement of the trolley, there will always be a lower portion of the track cable in front of it, since the rocker 6 gradually turns. When the cart passes by the supporting beam of the support beam 5, the beam will rotate in the opposite direction (Fig. 3), again lowering a section of the track cable in front of the load trolley that is sufficient to freely pass the support.

The subject matter of the invention.

An aerial ropeway with a fixed rope, on which the trolleys move under the force of gravity, is characterized in that, in order to facilitate the movement of the freight carriages at the intermediate supports, it is not possible to hang the rope at each intermediate support from below to the ends of the rocker swinging on the support 6
