Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable transport device, and in particular, the cable transport device can be arranged by bending a guide rope, that is, a transport path, and can be carried on any terrain or deep mountain forest by levitating the cargo with a balloon. It also allows lumber and other materials to be transported smoothly.

Traditionally, the methods for transporting timber cut from mountain forests are as follows:
Roads and rails were built in the mountains to transport goods by vehicle, but this had the drawback of being extremely expensive to transport from deep in the mountains, where the terrain was complex.

Therefore, recently, a method of transporting lumber using balloons has been considered.

On the other hand, rope transport devices using cables such as lifts are also known as a method of transporting lumber and materials, but due to the structure of conventional rope transport devices, guides that serve as transportation paths are known. Because the rope cannot be bent and arranged,
It is unsuitable for locations with complex terrain or for long-distance transportation, and it is extremely difficult to transport lumber floated by balloons from deep in the mountains using such rope transport devices.

This invention was made against this background, and includes a rotatable body having wheels that can be engaged with a guide rope. By suspending the lumber from a guide rope using casters, and by connecting a balloon to this floating body to levitate the lumber and transporting it by pulling it with a cable, it is possible to transport it even on a curved transport path. is possible,
It is an object of the present invention to provide a rope transport device that can easily and smoothly transport lumber from deep in the mountains in any terrain.

An embodiment of the present invention will be described below based on the drawings.

Fig. 1 shows an example of a cargo pod used in the cable transport device according to the present invention, where 1 is a guide rope arranged in the transport direction, and 2 is a U-shaped cross section guided by the guide rope 1. 3.3. . . . indicates a wheel having a recess that can be engaged with the guide rope 1 and this wheel 4.
This caster consists of a yoke 5 that holds the yoke 5 and a holder 6 that holds the yoke 5 rotatably around a vertical axis. It is constantly urged toward the guide rope 1 by a compression spring 8.

Two sets of casters 3 are added to the front and rear of the floating body 2 so as to sandwich the guide rope 1 from above and below, respectively, and the floating body 2 is supported by these casters.

9 is a holding frame provided at the bottom of the floating body 2;
A pulley 10 is rotatably attached to the lower part of the holding frame 9 parallel to the guide rope 1, and a drive cable 11 arranged parallel to the guide rope is wound around this pulley 10. The movable body 2 is pulled by a drive cable 11 via a pulley 10.

That is, if the tension of the cable is different before and after the pulley 10, the pulley rotates until one of the cables is loosened and comes to rest with the tension balanced, and the pulley and floating body 2 are transported in this balanced state. It is.

Note that the guide rope 1 is attached to the floating body 2 at the curve.
Notches 2a, 2b, and 2c are provided to prevent contact with the floating body 2, and locking portions 12, 12 are provided at the front and rear of the upper surface of the floating body 2 for securing a balloon, which will be described later.

Next, the structure and operation of the conveyance path curve of the conveyance device constructed as described above will be explained with reference to FIG.

In this type of cable conveyance device, the conveyance path is curved at the support portion of the guide rope.

In the figure, 13 is a support arm, and 14 is a support arm horizontally attached to the support support 13. The tip of this support arm is curved according to the bending of the guide rope, and an engagement member with which the guide rope can be engaged. An edge 15a is formed, the guide rope 1 is engaged with this engagement edge 15a, and a plate 1 with a similar engagement edge 15b is formed from the opposite side.
A guide rope is sandwiched between the guide ropes 6 and 6 to form a pipe-shaped guide rail.

Therefore, at the curved point of this column, the caster 3 of the floating body has the engaging edge 15a of the support arm 14 and the plate 16,
It will roll on the rail consisting of 15b.

Thus, the caster 3 is biased by the compression spring 8,
In addition, since the yoke 5 is rotatable, even if the wheel 4 moves from the rope to the rail or vice versa, the spring expands and contracts, allowing the wheel to rotate smoothly and the yoke to rotate according to the curve. Since the wheels follow the curvature of the rail, there is no risk of the wheels falling off.

On the other hand, at this curve point, as shown in the figure, the curvature of the drive cable 11 and the conveyance path do not match and the cable passes inside the conveyance path, resulting in a speed difference between the casters 3 and the pulley 10. However, at this time, the pulley 10 around which the cable is wound rotates to absorb this speed difference, so that the floating body can be transported safely.

That is, when the tensions at the front and rear sides of the cable wound around the pulley 10 are balanced, the pulley does not rotate, but if one of the cables becomes loose or the tension increases, the pulley rotates until the tensions on both sides are balanced. At the curve point, the pulley rotates until the cable tension is balanced, so at the curve point, the pulley rotates until the cable tension is balanced, preventing rapid acceleration of the floating object and allowing safe transportation. .

Note that the support column 13 is provided with a vertical roller 17 and a horizontal roller 18 for preventing friction with the drive cable 11.

Figures 3 and 4 show an example of the structure of a support when the guide rope is curved in the vertical direction.The tip of the support arm 14 supported horizontally by the support 13 is at a right angle It is then bent outward again to form an appropriate curve in the vertical direction, and an engaging edge 15a is provided along the edge.

A plate 16 having a similar engagement edge 15b and a curve is joined from the lower surface thereof, and the guide rope 1 is held therebetween.

Note that the bent piece 14a at the tip of the support arm 14 is configured to be narrower than the width of the notch 2c formed on the lower surface of the floating body 2, so that it does not come into contact with the bent piece 14a when the floating body passes therethrough.

Next, a system for transporting timber felled in a mountain forest by using the above-described transport device and a balloon will be described with reference to FIG. 5.

The drawing shows an embodiment in which the conveyance path is of an endless type, in which supports 13 are erected according to the terrain and the guide rope 1 is curved to form a curved conveyance path.

A plurality of floating bodies 2 are placed on this guide rope 1 at appropriate intervals, and each floating body 2 is connected to a three-stage balloon 19 by a rope, and the main rope of this balloon 19 is A locking metal fitting 21 is attached to the lower end of 20, and a lumber 22 and a weight 2 are attached to this locking metal fitting 21.
3 is suspended.

The drive cable 11 is connected to the winches 24 and 2.
5, each movable body 2 is pulled by the cable and transported.

Further, at this time, the weights 23 of each floating body are adjusted so that the buoyancy of the balloon and the weight of the cargo are balanced, so that a large amount of lumber can be easily and quickly transported from a distance with a small amount of power.

Furthermore, once the timber is lowered at the position indicated by the broken line in the drawing, the cable 11 is removed from the winch 24 and the floating body 2 is passed through.
Next, connect the cable 11 to the winch 24, and
An endless system can be realized by removing the floating body 2 from the casing and passing the floating body 2 through it.

In addition, when taking down the carried lumber, as shown by the broken line, the sub rope 27 is wound up with the winch 26, the lumber is removed from the locking fitting 21, and a weight that balances the buoyancy of the balloon is suspended instead. .

In this embodiment, an endless type was described, but the present invention can also be applied to a reciprocating type.

As explained above, the cable transport device according to the present invention is
A support pole erected along a conveyance route selected according to the topography, a guide rope supported by the support support and arranged to bend at the support part of the support support, and a guide rope approximately parallel to the guide rope. suspended from the guide rope via a drive cable disposed as such and rotatable casters having wheels that can be engaged with the guide rope;
and a floating body having on one side a pulley around which a part of the drive cable is wound, a balloon connected to the floating body and having a locking member capable of locking cargo and a weight, and a balloon having a locking member capable of locking cargo and weight; and a driving means, and the drive cable is driven while the cargo is levitated by the balloon to transport the movable body along the guide rope, so that the movable body can be transported even on a meandering conveyance path. As a result, it can be installed deep in the mountains in any terrain, and has the advantage of being able to transport lumber easily and smoothly.
