Description

[Detailed explanation of the idea] This invention relates to a conveyance device, and more details.

This invention relates to a transport device suitable for transporting wood from mountainous areas using standing trees or alternative supports.

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 fact that the conveyance route is too steep or in a narrow place, the location where trees are felled is not constant and changes as the work progresses, so even if the tracks for the conveyance equipment are laid, However, since it is a fixed installation, it may become obsolete as the work progresses.

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

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.

To this end, this idea is to construct a track in the air using supports in areas where there are no standing trees or standing trees, and to run a transport vehicle with the load supported by a tow truck along this track. It is characterized in that it can be easily and reliably attached and removed.

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 attached to each of suitable standing trees T at approximately the same height above the ground, and is suspended from the support cables 2. The carrier 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
, 130, respectively, are pivoted to the base ends, and these fittings 14, 14 are fixed to the standing tree T in two stages, upper and lower, at appropriate intervals. The support arm 12 is configured to form a cantilevered angle beam extending substantially horizontally to the side of the tree T.

This mounting bracket 14 (with a clamping piece 14a formed into a substantially chevron-shaped fold for clamping the outer periphery of the nine standing trees T).

A pivot piece 14b for pivotally attaching the support arm 12 or the reinforcing arm 13 is arranged to protrude in opposite directions on the outer periphery of a short cylindrical body part 14c.
A predetermined space is formed between the support rod 15 that penetrates through 4c and the outer periphery of the tree T, and by pressing the top and bottom of the support rod 15 against the tree, the bending resistance force of the support rod 15 is received and the above-mentioned clamping is performed. The piece 14a is pressed against the standing tree T so that the friction is high.

Therefore, the support rod 15 is connected to the main body parts 14a, 14a of the mounting brackets 14.14 arranged in two stages, upper and lower, with respect to the standing tree T.
It is attached to the standing tree T by passing through it.

A chain 17 with a chain hook 16 protruding from its lower end is wound around the outer circumference of the tree T, and the lower end of the support rod 15 is attached to the tree T.

In order to hold the support rod 15 against the tree T, as shown in FIG. It has a puncture ring 19 that can be hung at any point on the free end side, and a claw part 20 that locks this link 19, and is located outside of the titration tree T from the center of the support rod 15. Clamp lever 21 pivotally mounted
A buckle fitting 22 is provided, which tightens and fixes the chain 18 by a predetermined amount by rotating the clamp lever 210.
is formed.

In order to avoid damaging the skin of the standing tree T when tightening the chains 17 and 18, the chains 17 and 18 are covered with a plurality of rubber hose pieces 23 having appropriate elasticity.

As shown in FIGS. 4 to 6, the track body 3 has rank teeth 31 fixed to the lower surface of a rail having an inverted T-shaped cross section.
The driving wheels of the towing vehicle, which will be described later, are engaged with each other, and the wheels of the driving vehicle and the follower vehicle are placed 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 carrier vehicle 4, in which the support cable 2 is inserted into the closed space and the track body 3 is laid in the air, is towed by a towing vehicle 41 equipped with a power source as shown in FIG. Consists of following vehicles, etc.

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 rank teeth 31, and the rolling wheels 44 that support the weight of the towing vehicle 410 Follower cars 45, 46 are connected to this pulling car 41, which rests on the horizontal part 32 of the rail, and the wheels 47, 48 of each follower car are attached 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 are used to support the middle of timber B.

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

First, if there is a suitable standing tree T, attach it to the support 1.

That is, the support rod 15 fitted with the mounting brackets 14 and 14 is attached to a suitable tree T, the chain 17 is wound around the tree T using the chain hook 16 protruding from the lower end of the support rod 15, and the lower end of the support rod 15 is Attach it to the standing tree T.

Thereafter, the mounting brackets 14, 14 are moved along the support rod 15, and the support arm 12 is placed at a predetermined height above the ground.

and. Wrap the chain 18 at the upper end of the support rod 15 around the tree T, and attach the buckle fitting 22 at any point on the free end side.

As a result, the chain 18 is tightened and fixed to the tree T by a predetermined amount, and the reaction force acts on the upper end of the support rod 15,
The clamping piece 14a * 14a serves as a fulcrum and also acts on its lower end, and the clamping piece 14a receives the elastic resistance of the support rod 15.
, 14a are frictionally fixed to the standing tree T, and the support arm 12
, an angle beam composed of reinforcing arms 13 is constructed.

At that time, the engagement position of the buckle ring 19 (with respect to the claw portion 20 of the clamp lever 21) or the engagement position of the buckle ring 19
By appropriately selecting the position of the chain 18 that stops the hanging, a predetermined fixing force can be obtained even for standing trees T with different trunk diameters.

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 route.

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.
