Description

[Detailed explanation of the invention] This invention relates to a transportation device, and more specifically,
The present invention relates to a transport device suitable for transporting wood from mountainous areas using an alternative support.

The work of transporting felled wood from mountain forests to water reservoirs and sawmills at the foot of the mountain is one of the fields where mechanization and motorization are the least advanced. In addition to the transport route being too steep or in a narrow area, the location where trees are felled is not constant and changes as the work progresses, so even if tracks for the transport equipment are laid, Since it is a fixed installation, it may become obsolete as the work progresses.

Therefore, the reality is that cargo is transported using human and animal power, and this makes it easy to move and lay tracks as the logging work progresses, and even on steep mountain roads and narrow spaces. If there is something that can be done, it would be good news for this type of worker.

This idea was developed in consideration of the above-mentioned circumstances, and in order to make it possible to carry out cargo, especially wood, in mountainous areas mechanically and with power, it was designed to suit the particularities of the topography and conditions of mountainous areas. Another object of the present invention is to provide a transportation device that can be easily installed even in steep and narrow places, and that can easily install and move the equipment.

For this reason, the idea is to build the track in the air using standing trees or supports in places where there are no standing trees, and to run a transport vehicle with the load supported by a tow truck along this track.
The device is characterized in that it can be easily and reliably installed and removed from a standing tree or the like.

The details of this invention will be explained below with reference to the attached drawings.

Fig. 1 shows a transport device as an embodiment of the present invention, in which a support cable 2 is installed between supports 1 installed at approximately the same ground height on each of suitable standing trees T, and a support cable 2 is suspended from this. The transport vehicle 4 is configured to run along a track body 3 which is installed in the air at an appropriate height above the ground.

As shown in FIG. 2, the support body 1 includes a support arm 12 having a hook portion 11 formed at its tip for locking the support cable 2, and a tip of the arm 12 pivoted near the hook portion 11. It has a reinforcing arm 13, and both arms 12
．． Mounting metal fittings 14 and 14 are pivotally attached to the base ends of the tree T, respectively, and the fittings 14 and 14 are fixed to the standing tree T in two stages, upper and lower, at appropriate intervals.
This is done so that a cantilevered angle beam is formed that overhangs the side of the tree T.

The above-mentioned attachment is such that the chain 15 that is wrapped around the tree T is attached to the metal fitting 14 in order to fix the metal fitting 14 to the tree T.

Therefore, the upper and lower attachments will be explained using the lower one of the metal fittings 14, 14 as a representative.

As shown in FIG. 3, the mounting bracket 14 is constructed by hinged left and right pieces 17 and 18 on both sides of a piece of wood 16 to which the base end of the support arm 12 is pivotally attached. Hook 1 that hangs or hangs one end or the middle of the chain 15
9 is formed, and a lug 21 is formed on the chip 18 to insert an eye bolt 20 attached to the other end of the chain 15. By screwing and tightening a nut 22 to the eye bolt 20, the chain 15 can be attached to a standing tree. It can be wrapped around a T.

A predetermined number of rubber hose pieces 23 having appropriate elasticity are wrapped around the chain 15 so as not to damage the skin of the standout tree T.

As shown in FIGS. 4 and 6, the track body 3 has rack teeth 3 fixed to the lower surface of a rail having an inverted T-shaped cross section, and is designed to mesh with the drive wheels of a towing vehicle, which will be described later. The wheels of the driving vehicle and the following vehicle are mounted on the upper surface of the horizontal portion 32 of the rail to enable transfer.

The lower end of a two-pronged suspension body 35 whose upper end is connected by a pin 34 is removably pivoted to the vertical part 33 of the rail with bolts and nuts at an appropriate interval. The support cable 2 is inserted into the closed space, and the track body 3 is installed in the air.

As shown in FIG. 5, the transport vehicle 4 includes a towing vehicle 41 equipped with a power source, a follower vehicle towed by the towing vehicle 41, and the like.

First, the towing vehicle 41 has an engine 42 as a power source, and drive wheels 43 that are forcibly rotated by the output of the engine 42 mesh with the rack teeth 31, and drive wheels 44 that support the weight of the towing vehicle 41. rests on the horizontal portion 32 of the rail.

Follower cars 45, 46 are connected to this towing car 41, and the wheels 47, 48 of each follower car are connected to the horizontal part 32 of the rail.
It's on top.

The follower cars 45 and 46 are connected by a connecting rod 49 that is spline-fitted to each other, and the span between the follower cars 45 and 46 can be freely selected in relation to the cargo to be transported.

Each follower vehicle 45.46 has a luggage rack 50 on which wood B is placed.
is provided so that the ends of a plurality of pieces of wood B can be hung.

Especially when the wood B to be loaded is long and heavy,
Three follow-up cars will be used to support the middle of the timber B.

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

First, if there is a suitable standing tree T, the chain 15 is wound around it, the mounting bracket 14 is fixed, and the support 1 is set at a predetermined height of the standing tree T.

In other words, the eye pole fixed to one end of the chain 15)
20, loosen the nut 22 screwed onto the chain 15, and set the length of the chain 15 longer.
A hook 19 is provided on the piece 17 of the mounting bracket 14 by wrapping the ring 15a at an appropriate place so as not to loosen it.
Stop hanging.

After that, tighten the nut 22 and install the metal fitting 14 on the standing tree T.
It is fixed firmly.

At this time, the chain 15 is covered with a plurality of rubber hose pieces 23, which are in contact with the surface of the tree T.
Also, by appropriately selecting the ring 15a to hang on the hook 19, you can hang trees of different thicknesses.
It can also be installed on.

After fixing one of the pair of mounting brackets 14.14 in this way, the other mounting bracket is fixed at a predetermined distance in the vertical direction using the bracket 14 or in the same manner as described above, and the support arm 12 is fixed. It is installed almost horizontally protruding from the standing tree T.

As shown in FIG. 1, such supports 1 are arranged at appropriate intervals along a desired transportation route and at a predetermined ground height relative to a columnar object such as a standing tree T.

Thus, the support cable 2 inserted through each suspension body 35 of the track body 3 is locked to the hook part 11 of each support body 1,
By tensioning the support cable 2, the track body 3 is installed in the air along a desired conveyance path.

In this way, the transport vehicle 4 is run along the track body 3 supported by the support body 1 via the support cable 2,
The driving wheels 43 of the traction vehicle 41 are engaged with the rack teeth 31, the rolling wheels 44 are placed on the upper surface of the horizontal portion 32 of the rail, and the following vehicles 45 and 46 are connected to the traction vehicle 41.

Although the following vehicle 45 and the towing vehicle 41 may be rigid, the following vehicles 45 and 46 are connected by a connecting rod 49 that is spline-fitted to each other so that the shaft length can be adjusted. The wheels 47, 48 are placed in rolling position on the water extension 32 of the rail.

The interval between the following vehicles 45, 46 is determined by the length of the timber B to be transported. If the timber B is extremely long or heavy, another following vehicle may be used in addition to the following vehicles 45, 46. Link.

The additional follow-up vehicle may be placed in the follow-up vehicle 45, 46 or further connected to the follow-up vehicle 46 depending on the condition of the cargo.

Since the follow-up vehicles 45 and 46 have luggage racks 50 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 43 meshing with the rack teeth 31 using the output of the engine 42 of the towing vehicle 41.

As is clear from the above explanation, according to the conveyance device of this invention, the supports are arranged at appropriate intervals using suitable trees, etc., and the support cables installed between them are arranged. Since the track body is laid in the air through the cable, and the transport vehicle is run along the track body, it is relatively easy to lay the track body even on steep mountain roads or in narrow places, and it is also easy to attach the support body to standing trees. Since this is done using a chain that has a variable circumference and is detachable, it can be reliably attached even to standing trees of different thicknesses, and the work is simple, making it easy to lay a transportation path or move it. can be done.
