On the other hand, in the forest, in order to maintain the growth of the main trees, it is required to lower the miscellaneous trees and thinned wood to the accumulation place of the foot of the mountain. This work is also required when installing transmission lines in the forest. However, since miscellaneous trees and thinned wood are heavy items with low added value, it is not profitable if a large and complicated cableway device is used.
However, miscellaneous trees, thinned wood, etc. have utility value as biomass, and if they can be transported from the forest at low cost, their effective use will be promoted, which will contribute to the improvement of the forest environment.
Therefore, the present invention is easy to install because of its simple structure, and can be carried out at a low cost of about 2,000 to 3,000 yen / ton or less, where the load can be used as biomass from the upper part to the lower part of a slope such as a forest. An object of the present invention is to provide a simple transport cableway device and system.

According to one aspect of the present invention, a cableway track provided in a state suspended in the up-down direction of a slope, a moving body that moves while being guided by the cableway track, and load accommodating means connected to the mobile body And a pulling wire that is arranged in a loop shape along the cableway trajectory and to which the moving body is fixed, an electric motor that is drivably connected to the pulling wire, and a storage battery. The change in potential energy when moving from the upper part to the lower part along the cableway trajectory by its own weight together with the load accommodating means is collected and stored as electric energy by regenerative braking of the electric motor via the pulling wire. A simple carrying cableway device is provided. It is convenient that the load accommodating means is detachably attached to the moving body. Moreover, it is convenient that this moving body is detachably fixed to the pulling wire.

Furthermore, according to another aspect of the present invention, the above-described simple carrying cableway device is provided as a trunk line, and further provided with one or more branch lines provided by branching from the trunk line, each branch line including a cableway track, Provided is a simple transporting cableway system comprising a moving body that is guided and moved by the cableway track, and a load accommodating means connected to the moving body. It is convenient to provide the load accommodating means for the branch line so that it can be transferred to the trunk moving body.
As described above, the number of branch lines to be provided at the same time may be one or more, and in short, it may be set to the most efficient number of lines depending on the work setup.

  According to the present invention, when the moving body moves with its own weight from the upper part to the lower part of the cableway track together with the load receiving means loaded with the load, the loop-shaped pulling wire connected to the moving body is moved to the pulling wire. Since the regenerative braking action of the connected motors is generated, it is possible to stably carry out the load from the slope with a simple configuration, and at the same time, the potential energy of the load can be recovered as electric energy. In addition to being able to be used as power for unloading and controlling equipment, it is easy to install as a whole, and it is possible to obtain a low-cost and easy-to-use cableway device and system for efficient use of energy.

  Hereinafter, although the present invention will be described based on the illustrated specific examples, the present invention is not limited to the specific examples.

  FIG. 1 shows a schematic diagram in which the cableway system for simple conveyance of the present invention is applied to a slope of a forest. There are valleys, rivers and forest roads in the middle of this forest. As is clear from FIG. 1, one simple transport cableway system according to the present invention is provided from the top of the forest to the river, and another from the top of the forest to the forest road. Each of the simple transport cableway systems has the same configuration. The trunk line 1 is provided from the top of the forest to the river or the forest road along the up and down direction of the slope, and the fish bone is branched from the trunk line 1. A plurality of branch lines 2 arranged in a shape are provided. The trunk line 1 may be installed toward the point when a forest road is installed in the vicinity of the cut-out point, and toward the river when the forest road is not in the vicinity and there is a river. The trunk line 1 is usually arranged so as to pass through a place where the timber to be cut out is most likely to be collected, and is installed almost linearly from the summit to the unloading base 6 such as a mountain skirt, but some bending is allowed.

As shown in FIG. 2, the main line 1 includes a cableway track 10 provided in the vertical direction of the slope, a moving body 20 that moves while being guided by the cableway track, and a belt-pulley along the entire length of the cableway track 10. The loop-like pulling wire 30 is provided.
The cableway track 10 may be made of any material as long as it guides the moving body 20 in a slidable manner, and can be made of at least one of a single rope, wire, rail, and the like. When these materials are used, the cableway track 10 can be extended between a pair of standing trees 11 and 11 that are vegetated adjacent to the forest as pillars. For example, as shown in FIGS. 2 and 3, a rope 12 can be bridged between a pair of adjacent standing trees 11, 11, and the cableway track 10 can be suspended from the rope 12. The cable track 10 is usually installed linearly along the slope, but may be bent somewhat. However, when a large number of standing trees are dense and the cableway track 10 cannot be installed in a straight line, it is permitted to cut some standing trees. In addition, when there is no suitable pair of standing trees 11 and 11 over which the rope 12 is bridged, a part of the columns 13 and 13 using thinned wood may be reinforced with a reinforcing branch line. In any case, because the lumber to be carried out at one time is short and light, the cableway track 10 can be installed by making the best use of standing trees, and the alteration of the natural environment by the cutting of standing trees and the installation of struts is minimal. It can be stopped to the limit. By arranging a large number of such ropes 12 at predetermined intervals along the slope, the cableway track 10 is installed in a suspended state.
In addition, when supporting using a standing tree, it is good to protect with a batten etc. so that the part which winds a rope around a standing tree may not be damaged.

  The moving body 20 can be slidably arranged in the vertical direction of the slope while being guided by the cableway track 10 by various methods as shown in FIGS. 4a to 4c. FIG. 4 a-1 shows an example in which a wire is used as the cableway track 10, and the cableway track 10 is suspended from a rope 12 via a connecting fitting 15. The connecting fitting 15 is configured to hold the rope 12 at the upper end and hold the cableway track 10 at the lower end. The movable body 20 is composed of a pair of half-symmetrical halves including a plate-like lower end portion 21 having two screw holes and a curved jaw portion 22 extending above the lower end portion 21, and the two halves are mutually connected. In combination, the screws are inserted into the screw holes in the lower end 21 and fixed together. As a result, a slit 23 is formed between the jaws 22 facing each other to allow the coupling fitting 15 to pass therethrough. In addition, the moving body 20 may be integrally formed into a shape in which both the half portions are assembled. A roller 24 is disposed inside the upper portion of the jaw 22. A hook 26 is attached to the lower end portion 21 so that the load accommodating means 40 can be detachably connected. Thus, the movable body 20 can move in the vertical direction of the slope along the cableway track 10 by inserting the cableway track 10 into the inner space of the jaw 22 and placing the roller 24 on the upper surface of the cableway track 10. . The moving body 20 is normally used in the form of embracing the cable track 10 and is provided with an index wire restraining tool above the hook 26 below the moving body 20, and the moving body 20 is detachably fixed to the pulling wire 30 by this restraining tool. The As shown in FIG. 4 a-2, the catching tool is shaped like a bowl so as to accommodate a generally T-shaped clasp 25 rotatably attached to the lower end 21 and a head of the T-shaped clasp 25. The traction wire 30 can be fixed by rotating the T-shaped clasp 25 in a state where the traction wire 30 is accommodated in the wire cabin 29 and accommodating the head in the wire cabin 29. (See FIG. 4a-1 (1)). Then, by rotating the T-shaped clasp 25 and detaching its head from the wire cabin 29, the pulling wire 30 can be detached from the moving body 20 with one touch (see FIG. 4a-1 (2)). For example, the load accommodating means 40 that has moved along the branch line 2 and arrived at the small accumulation area is transshipped to the trunk line 1, but if the loading table serving as this place is set to be slightly higher, the hook 26 of the mobile body 20. By delivering the load accommodating means 40 and rotating the T-shaped clasp 25, the tow wire 30 can be fixed to the catching tool with one touch, and the moving body 20 automatically moves according to the speed of the tow wire 30, and the load is accumulated. It is transported to the field. After arriving at the collection area, the T-shaped clasp 25 can be released by one-touch by rotating the T-shaped clasp 25. It is good also as a structure which is made to rotate by contacting the stopper (not shown) installed before the return | turnback point of 30, and to release the catch of the pulling wire 30 automatically. As shown in FIG. 2, the loop-shaped pulling wire 30 is arranged in a belt-pulley relationship. Specifically, the pulley at the summit and the pulley of the electric motor 50 that can generate regenerative braking at the foot of the forest. Is arranged so as to be driven by the electric motor 50. The electric motor 50 may include a storage battery (not shown) that stores electricity generated by the regenerative braking. Further, the return portion of the pulling wire 30 facing the moving body 20 is inserted and guided through an annular guide 14 (see FIG. 4 a-1) provided at the upper end of the connection fitting 15.

  Alternatively, the moving body 20 can be placed on the cableway trajectory 10 in a manner as shown in FIG. 4b. In addition, in FIG. 4b, the part shown with the code | symbol similar to FIG. 4a-1 means having the structure similar to FIG. 4a-1. In FIG. 4 b, a rail 110 having a reverse T-shaped cross section is used as the cableway track 10. The rail 110 is suspended from the rope 12 via a connecting fitting 115. The upper end of the connecting fitting 115 is connected to the rope 12 in the same manner as the connecting fitting 15 in FIG. 4a-1, and the lower end of the connecting fitting 115 is formed in a bifurcated fork shape. The part is inserted and pinned. The moving body 20 has a pair of rollers 24 having substantially the same shape as that of FIG. 4 a-1 and facing the inside of the jaw portion 22. Thus, the moving body 20 allows the rail 110 to be inserted into the inner space of the jaw portion 24 and the roller 24 is placed on the horizontal overhanging portion at the lower end of the rail 110, so that the up and down direction of the slope along the cableway track 10. Move to.

  FIG. 4c shows a modification of FIG. 4b, and an example in which a C-shaped member 210 such as a curtain rail is used as the cableway track 10 in place of the rail 110 whose cross section in FIG. Show. In this case, the pair of rollers 224 of the moving body 20 is fixed to each end portion of the pin 228 inserted through the plate-like piece 227 protruding from the upper end of the moving body 20. Thus, the moving body 20 moves in the vertical direction along the cableway track 10 by inserting the pair of rollers 224 through the rail 210 and placing the roller 224 on the inner horizontal portion of the rail 210.

  The load accommodating means 40 is suspended from the hook 26 of the moving body 20, but the load accommodating means 40 may be any of a rope, a net, a box, a saddle, and the like. FIG. 3 shows an example in which felled trees are bundled with a rope and the rope is connected to a hook 26. In this case, the load accommodating means 40 is a rope. Further, as shown in FIGS. 2 and 5, the load accommodating means 40 may be a boat-shaped container. In this case, as shown in FIG. 1, it is possible to carry the cargo together with the container from the accumulation base adjacent to the river to the downstream collection site and transport it by truck from there.

  The branch line 2 shown in FIG. 1 is provided to be branched from the main line 1 from the middle of the main line 1 and is usually provided in a plurality in the shape of a fish bone. And the small accumulation base 3 is installed in the location where the branch line 2 branches from the trunk line 1, and it is set as the delivery place of the load from the branch line 2 to the trunk line 1. FIG. Each branch line 2 is basically composed of a cableway track, a moving body that moves while being guided by the cableway track, and a load accommodating means connected to the moving body. The cableway trajectory of the branch line 2, the moving body, and the load accommodating means can all have the same configuration as that described for the trunk line 1. The moving body is basically moved by human power. Therefore, the branch line 2 is preferably provided on a gentle slope near almost horizontal. For example, the moving body connected with the load accommodating means is directed to the small accumulation base 3. When it is pushed by human power, the slope is inclined so that it automatically stops in the vicinity of the small accumulation base 3, or the small accumulation base 3 can be stopped without using large force if it is stopped halfway. It is good to install on the slope of the grade which can be carried to. However, this does not prevent the branch line 2 from having the same configuration as that of the trunk line 1 including a pulling wire and an electric motor. In any case, the load accommodating means that has reached the small accumulation base 3 can be removed from the hook of the moving body 20 of the branch line 2 and attached to the hook 26 of the moving body 20 of the trunk line and can be easily transferred. When transferring to the moving body 20 of the main line 1, it is desirable to be able to adjust it to a predetermined length with something like a small chain block or a shimmer, and measures that do not involve large physical labor are appropriately adopted for the transfer. It is desirable.

  Next, the operation of the above specific example will be described. When carrying out miscellaneous trees and thinned wood from the forest, usually the miscellaneous trees and thinned wood are gathered from the branch line 2 to the small accumulation base 3 and finally used to the accumulation base 6 of the mountain using the simple conveying cableway device of the trunk line 1. It is carried out. Prior to carrying out, the cableway device for simple transport of the trunk line 1 moves the moving body 20 to the summit with the empty load accommodating means 40 attached. At the time of this movement, a chain saw necessary for felling and materials and equipment used for unloading the loaded tree can be carried on the load accommodating means 40. This movement may be performed manually, but is usually performed by using an electric motor 50 that drives the loop-shaped pulling wire 30. Then, after the miscellaneous trees and thinned wood near the summit are accommodated in the load accommodating means 40, the load accommodating means 40 and the moving body 20 move from the upper part to the lower part along the cableway track 10 by their own weight. When passing through each small accumulation base 3, miscellaneous trees and thinned wood collected there are loaded into the load accommodating means 40, so that the small collection base 3 can be carried out.

  While the load accommodating means 40 and the moving body 20 move by their own weight along the cableway track 10 from the upper part to the lower part, the loop-shaped pulling wire 30 moves in the opposite direction to the case of moving to the summit. At this time, the electric motor 50 rotates in the same manner. At this time, since the electric motor 50 exerts an action of braking the pulling wire 30 by regenerative braking, the movement of the load accommodating means 40 and the moving body 20 is stabilized, and the electric motor 50 functions as a generator, and the load accommodating means. Power generation is performed by converting a change in potential energy of 40 and the moving body 20 into electric energy. This electric power may be used for night lighting around the cableway device, or stored in an appropriate storage battery to serve as electric power or control power for the motor 50 when moving the load accommodating means 40 and the moving body 20 to the summit again. It may be used for other purposes. In addition, if there is a point where a head such as a waterfall can be made nearby, a portable small hydraulic power may be installed to chip the wood at the accumulation location.

  It is convenient to install the mountain summit base 6 at a point where it can be transported by a truck or the like on a forest road, or on the bank of a valley or river. When installed on the banks of valleys and rivers, it is advantageous to cut the wood that has been cut and carried out from the mountains into the optimum size for flowing into the river at this accumulation base 6 and dry it naturally to reduce the weight. Then, wrap the chopped wood into a certain unit size with a tough transportation network, put it into the river in anticipation of favorable conditions such as when the river is flooded, and collect it at a collection place that can be transported by a downstream truck etc. By carrying it, it is possible to construct an economically applicable transportation system together with the cableway system of the present invention.

  If a thin piece of timber skin flows into the river and causes pollution, or if you want to use the leather as a resource, instead of the transport network, a tough and lightweight transport bag with a shape that easily floats in the river, For example, it is possible to wrap wood in a rugby ball-shaped bag or a boat-shaped bag as shown in FIG. In this case, it is possible to add buoyancy to the transport bag with air or a foaming agent. It is preferable that the above-described transport network and transport bag have a yellow or other conspicuous color and have a structure that can be easily recovered from a river by attaching a recovery hook or the like.

  The simple transport cableway device and system of the present invention can be easily installed using lightweight materials without making major changes to the natural environment, and when unloading loads such as miscellaneous trees and thinned wood from the mountaintop Since the change in potential energy can be changed to electrical energy, it not only contributes to the effective use of biomass and contributes to the conservation of the forest environment, but also achieves energy savings. It is very useful. Especially, the cableway device and system for simple transportation of the present invention is highly useful as a method for carrying out small-sized timber at a low cost when mainly using miscellaneous trees and thinned wood of a forest for biomass. It is preferable for transporting a short load of about 50 to 100 kg.
