Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an overhead cableway for collecting and transporting materials that can cover the entire area over a wide area and can suspend and transport materials such as wood from any point.

Traditionally, overhead cableways have been used as a means of transporting wood from, for example, mountains and forests, and the major feature of overhead cableways is that they can be transported in steep areas such as mountains and canyons much more easily than other transportation methods. There are several advantages that can be achieved.

However, when transporting cut timber from a rectangular logging area 61 as shown in FIG. Shaded area 63
After completing carrying out the felled timber inside to the road side, one of the support columns 64 is moved to the side by a predetermined distance, and the overhead cableway 62a is re-erected. It is necessary to sequentially re-string the ropes to carry out the removal of the cut wood, which requires a tremendous amount of labor and expense, and also makes it difficult to suspend and lift the material to a desired point within the transport area. For this reason, for example, during thinning in mountain forests, when the thinned wood is carried out, the remaining standing trees and the carried out felled trees are damaged by impact or the like. Also,
When transporting through the air, etc. over non-logging areas,
Furthermore, the use of cross-cutting cables and hoisting cables for hooks, etc., which serve as a means of hoisting transported objects, devastates the mountain forests in the passage areas, and therefore it is necessary to clear trees and thin rows to create passageways for the cables. arise. Furthermore, a worker must always be present at the loading/unloading position when loading and unloading the transported items, which has many disadvantages such as requiring a great deal of labor and being dangerous.

In addition, as shown in Fig. 2, which is another conventional implementation, when transporting cut timber from such an L-shaped terrain, there are many disadvantages similar to those mentioned above, and in addition, two A major technical and economic drawback was that a two-stage lumber collection method (or a multi-stage lumber collection method depending on the terrain), which required a main rope, had to be adopted.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a system that has a simple structure, is easy and safe to operate, is technically and economically advantageous, and can transport materials such as cut wood from any point in the transport area, such as a logging area. An object of the present invention is to provide an overhead cableway for collecting materials that can be carried out.

A radio wave receiving means 35 is provided in the main carrier 5, and the control command received by the receiving means 35 is transmitted to the hydraulic equipment 17, which starts the power source 9, acceleration,
Operation control is performed during stopping, engagement and disengagement of the clutch 10, and switching of the transmission 11. The command to the receiving means 35 by radio waves is issued by the transmitting means 36 operated by a person located at a safe and visible place on the ground. The various commands mentioned above, such as engine starting and clutch engagement/disengagement, are issued using radio waves with a single frequency.
As is well known, by modulating the radio waves in various ways and transmitting them, it is possible to send various desired commands to the remote receiving means 35. Note that 37 is a receiving antenna.

Further, the main carrier 5 is provided at the front and rear ends of the main carrier 5.
The end of the tow rope 38 that pulls and moves is tied to form an endless rope, and the tow rope 38 is wound around an endless drum 39. Furthermore, a contactor 40 for connecting and disconnecting current for the receiving means 35 is protruded from the left end of the main carrier 5 in FIG. A collision piece 41 that comes into contact with the contactor 40 is provided with an operating cable 42 for moving the collision piece 41 hanging down to the ground.

In addition, the main carrier 5 is provided with, for example, a tow for preventing the main carrier 5 from being moved by the tension of the support ropes when the main carrier 5 is tightened and stopped at a desired position and the support ropes are stretched, which will be described later. Known means for preventing reverse movement, such as locking the cable 38, is provided.

Next, an example of cable tensioning using the above-mentioned radio-controlled main carrier 5 will be described.

In FIG. 5, reference numeral 51 indicates a timber cutting area, and in order to carry out felled wood by thinning or complete felling in the entire area of the area 51, first
In order to stretch the main rope 1 longitudinally across the mountain, a support 2 on the mountain side and a support 3 on the unloading side are erected. Next, the main carrier 5 is suspended from the main rope 1, and first, in order to let out the first rope 18 from the first winding means 12,
A thin lead rope (not shown) is attached to the tip of the cable 18.
are tied together, wound around the first guide pulley 30, and suspended on the ground. The lead rope is pulled out across the logging area 51 to the side post 52 position, and finally
The cables 18 are tied to the side struts 52 to complete the support cables 53. In addition, an auxiliary carrier 54 is provided on the support rope 53 so as to be able to travel back and forth along the support rope 53. The secondary carrier 54 has the third and fourth carriers of the main carrier 5.
A third rope 20 and a fourth rope 21 extending from the winding means 14 and 15 are tied together as a tow rope 55, and the fourth rope 21 is wound through a pulley 56 provided near the side strut 52, The secondary carrier 54 is configured to be able to reciprocate, that is, travel alternately, on the support ropes 53. Further, the second rope 1 extending from the second winding means 13
9 is pulled out in the same direction and completely opposite to the first rope 18 stretched as the support rope 53, and is attached to the side strut 58 as a safety rope 59, preventing the main carrier 5 from being pulled toward the sub-carrier. It functions as a support for the power of 1 and ensures safety.

Therefore, when the cable is strung in this way, and the main carrier 5 is positioned as shown in position A in FIG. This is the area along the railway line. Therefore, move the main carrier 5 along the main rope 1 at the arrow 69 in FIG.
If it is moved again in the 69 direction, the entire lower half 51a of the logging area 51 is covered, and the cut wood in the lower half 51a of the logging area 51 can be easily collected directly under or near the main rope 1. It is.
Similarly, the upper half 51 of the logging area 51 in FIG.
The work of collecting the felled wood in b. is also easily accomplished.

Due to the maneuverability of the main carrier 5, the felled timber collected immediately below or in the vicinity of the main rope 1 can be extremely easily transported to the position of the pillar 3 on the transport side, which is the road side. In other words, the main carrier 5 functions as a so-called winch when operating to drive the sub-carrier 54 as described above, and functions as a carriage when transporting material up to the position of the pillar 3 on the road side.

As is clear from the above description, according to the present invention, when transporting objects such as wood from locations such as mountainous areas that cannot be transported by other means of transport, the following steps are required. It has such remarkable effects.

In other words, the main rope is strung across the unloading surface area,
A main carrier whose operation is controlled by radio waves is suspended from the main rope, and the main carrier is provided with four ropes that can be operated in and out, and the cables are used to cross the carrying-out surface area. (1) Usage The total length of the cables to be carried out can be short, and the cable tensioning is simple, and there is no need to re-string the main rope, which is very labor-intensive as in the conventional method. Suspension lifting can be carried out reliably, and when used, for example, in a thinned area of a mountain forest, the remaining standing trees will not be damaged by impact or the like, and therefore the thinned wood can be carried out unscathed.

(2) One of the four ropes was tied to the strut in the exact opposite direction to the main rope to serve as a safety rope, so when collecting wood using the support rope, it could be attached to the main rope in one unfavorable direction. The force of can be canceled by the safety rope,
Dangerous stresses occurring in the main rope can be prevented.

(3) There is no need for horizontal cables for hooks, etc., which are the means for lifting the transported object, and there is no need for the hoisting cable to hang down to the ground. There is no inconvenience of disturbing the trees, and if the device according to the present invention is used, for example, in a thinned area of a mountain forest, it will not damage remaining standing trees or trees in a non-cutting area.
There is no need to perform clearing or row thinning to create paths for hanging cables, and ideal thinning and forestry management can be achieved.

(4) There is extremely little work required to re-string the cables, and the operation can be controlled remotely from the loading/unloading site with good visibility through wireless operation, resulting in a significant reduction in labor compared to conventional methods. and ensure safe work.

(5) Since the device according to the present invention has an extremely simple configuration, maintenance and inspection of the device is easy, and the usable life is extremely long.
