Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transportation device that uses standing trees, and more particularly, to a transportation device that makes it possible to collect cargo by using the power source of a towing vehicle that constitutes the transportation device.

The work of transporting felled timber from mountain forests to lumber yards and sawmills at the foot of the mountain is one of the fields where mechanization and motorization are lagging behind. In addition to the transport route being too steep and narrow, the location where trees are felled is not fixed and changes as the work progresses, so even if tracks for the transport equipment are laid, If it is a fixed installation, it may become obsolete as the work progresses, resulting in the facility becoming idle.

Therefore, the reality is that cargo is transported using human power or animal power, and this makes it easy to move and lay tracks as the logging work progresses, and it is also easy to move on steep mountain roads or in narrow spaces. It would be good news for such workers if there was something that could be laid down.

In addition, if the work of lifting the wood to a loading platform for transport or unloading the wood onto the ground after transport could be done mechanically, it would be even more convenient in addition to the above-mentioned transport work.

This invention takes into account the above-mentioned circumstances, and makes it possible to carry out cargo, especially wood, in mountainous areas mechanically and with power, and also to adapt it to the particularities of the topography and conditions of mountainous areas. This is a transportation device that can be easily installed even in steep and narrow places, and for this purpose, the track is built in the air using standing trees or supports in places where there are no standing trees, in other words, it is suspended in the air. A transport vehicle supporting the cargo is run along this track with a tow truck, and as necessary, appropriate trees are selected from among the surrounding trees.
Where the span of standing trees is too large, gate-shaped supports can be used to make it easier to lay or change tracks. This feature is characterized in that it can be carried out dynamically using the power source of the constituent tractors.

Hereinafter, details of the present invention will be explained with reference to the accompanying drawings. The transportation device of the present invention is composed of a support 10 that supports a track relative to the standing tree, a track 20 suspended between the supports 10, a transport vehicle 30 that runs along the track 20, and the like. .

In the figure, 50 indicates a chain or band that ties the lower end of the support 10 to the standing tree T, and this chain also has the function of preventing the support 10 from sinking into the ground.

Next, the actual track construction and transportation of the transportation device of the present invention will be explained.

First, if there is a suitable standing tree T, attach support 1 to it.
Add 0. That is, the support bodies 11 and 12 are aligned with the thickness of the standing tree T, and an appropriate spacing is maintained by selecting the amount of insertion of the horizontal members 13a and 13b, and the frame arms 15 and 16 are
sandwiching the sides of the tree T, positioning the horizontal members 13a and 13b on the front side of the tree (the side where the track body 20 is located), and positioning the locking arm 17 on the back side of the tree,
The entire structure surrounds the tree T, and the lower end of the support 10 is fixed to the tree T with a chain 50. In this case, the support 10 is attached by applying a patch such as a sponge so as not to damage the standing tree.

Then, the fitting end 18a of the track support arm 18 is fitted into the arm receiver 14 of the horizontal member, and the support bodies 11,1
2, the track support arm 18 is attached so that it can rotate around the attachment end. When supporting the track 20 using the wire 24, the track support arm 1
A wire 24 is passed through a locking part 19 provided at the end of the wire 24, and the suspension body 23 is supported by a U-bolt 25 to the wire 24, so that the track body 20 is suspended.

Moreover, when a wire is not used, the suspension body 23 of the track 20 is bolted directly to the support piece 19d of the locking part 19.

If there is no suitable standing tree T, or if there is a standing tree but the span is too large to withstand the weight of the transport vehicle 30 and the cargo B, the gate-shaped support 40 should be erected at an appropriate location. Set up In other words, the subsidence prevention bodies 45 are mounted and fixed on the pillar bodies 41 and 42, and the track 20 is attached to the horizontal member 43 to prevent the track bodies and wires from loosening.

The carrier vehicle 30 is made to travel along the track 20 supported by the support body 10 in this way, and the drive wheels 33 of the towing vehicle 31 are brought into mesh with the rack teeth 22, and the rolling wheels 34 are moved between the flanges of the track body 21. 2a
The following vehicles 35 and 36 are connected to this towing vehicle 31. Although the following cars 35 and the towing car 31 may be rigid, the following cars 35 and 36 are connected by a connecting rod 37 that is spline-fitted to each other so that the shaft length can be adjusted. ring 5
a, 36a are placed in a state of rolling on the flange 21a of the track body 21. The interval between the following vehicles 35 and 36 is determined by the length of the timber B to be transported, and if the timber B is extremely long or heavy, another following vehicle may be used in addition to the following vehicles 35 and 36. Link. Depending on the condition of the cargo, the additional following vehicle may be positioned between the following vehicles 35 and 36, or may be placed between the following vehicles 36 and 36.
Make it more connected.

Since the following vehicles 35 and 36 have luggage racks 38 on which the timber B is placed, the ends of the timber B are placed and fixed thereon. Actual traveling is carried out with the drive wheels 33 meshing with the rack teeth 22 using the output of the engine 32 of the towing vehicle 31. In this case, the drive shaft 331 and the drive wheel 33 are coupled to each other via a disc 332.

In addition, in order to load the felled timber B lying on the valley surface onto the transport vehicle, it must first be pulled, and the following work is performed for this purpose.

First, when the drive wheel 33 is disengaged from the drive shaft 331 and power from the engine 32 as a drive source is transmitted to the drive shaft 331, the drive wheel 33 is not driven, but only the winding drum 333 is driven. Then, the cargo handling wire 334 is wound up, thereby pulling the wood B together.

In any of these operations, it is preferable to connect the towing vehicle 31 to an appropriate location with a chain 336 so that it does not move unexpectedly.

As is clear from the above explanation, according to the transportation device of the present invention, suitable standing trees can be used to support the vehicle, and in areas where there are no standing trees or where there are wide gaps between trees, gate-shaped supports can be used. Since the tracks are supported by wire ropes, the tracks can be easily constructed even in mountainous areas with poor location conditions, and can be easily removed. Then, the desired transportation work can be carried out by loading lumber etc. onto the follower vehicle and towing it with the towing vehicle, and by fixing the movement of the towing vehicle and driving the drive shaft via the clutch, the winding drum can be moved. Loading and unloading of cargo can be easily performed by winding or unwinding the cargo handling wire.
