Description

[Detailed Description of the Invention] This invention relates to a transportation device, and more specifically, to a single-track transportation device suitable for transporting wood from mountainous areas.

Conveyance equipment using single tracks can perform efficient cargo handling using mechanical power, and is particularly popular in orchards developed in mountainous areas such as manganese, and can be run even on steep slopes. Because it is possible, it is also being used to transport wood from mountainous areas.

However, the single track used in this transportation device has a structure in which the single track is attached to the upper end of a support that is erected on the ground, and the support is erected by driving it into the ground, so it is fixed. Once laid, the track cannot be easily moved to another location.

However, in forest logging, the logging location changes as the logging work progresses, and if the track for the transport vehicles to run is semi-permanently laid, it is extremely inconvenient to load the felled wood.

Therefore, it is desirable to be able to easily move the single track as the logging location changes.

However, if the supports supporting the single track are installed by driving them into the ground, it is inappropriate for the track to be installed in mountainous areas.

This invention is intended to provide a transportation device that is relatively easy to install even in narrow and sloped areas such as mountainous areas, taking into consideration the conditions described above.

To this end, the struts supporting the single track are characterized by having their lower ends erected on the ground, and some of the struts are attached to standing trees with support arms. be.

An embodiment of the conveying device according to this invention will be described below.

In the figure, reference numeral 10 is a hollow single track with engaging teeth 11 provided on the lower surface, and a unit body 10a of an appropriate unit length is a joint 12.
It is composed of connected.

The joint 12 is fitted into the ends of adjacent single track unit bodies 10a, and a connecting bolt 13 passes through the overlapped portion, and the end 13a of this connecting bolt 13 is connected to the upper end of the support column to be described later. It passes through the track support metal fittings provided in the hole and is individually defined by a hollow (13b).

Reference numeral 20 indicates a support column, which is composed of a support base tube 22 that is inserted into a hollow support tube 21 that is inserted into each other, and both tubes 21 and 22 are telescopically connected to each other. It is shaped like a mold and can be fixed to any desired length with bolts 23.

A flange 24 for a load receiver is attached to the lower end of the column base pipe 22 to prevent it from sinking into the ground, and a mounting bracket 25 for attaching the single track 10 to the column 20 is attached to the upper end of the flange 24.
is fitted and fixed to the support pipe 21 with bolts 26, and a flange-type bolt receiver 25a is provided protruding from one side of the mounting bracket 25.

The connecting bolt 13 is inserted through the bolt receiver 25a and is fastened with the collar H3b.

Further, among the groups of 20 columns supporting the single track 10, support devices 30 are arranged for each appropriate number of columns, and the support devices 3
0 has a support arm 32 at the upper end of a column 31 similar to the column 20.
is fixed, and the end of the support arm 32 has a plate-shaped flange 32.
The side surface of the single track 30 is fixed with bolts 33, and a fixture 34 that surrounds and fastens the standing tree T is fixed to the other end of the support arm 32.

In the fixture 34, one end of a wire 36 is connected to the end of a band 35 having a stop hole 35a, a buckle 37 is fixed to the end of the wire 36, and a pin 37a of the buckle 37 catches the stop hole 35a. , the standing tree T is fastened via the cushion K by turning the buckle 37.

The unit of the single track 10 supported by the end of the support arm 32 of the support device 30 is connected to the end of another unit by a joint.

For the single track 10 laid in this way, the transport vehicle 4
0 is easily set, and the towing vehicle 41 has a drive wheel 41a with a single track 1
It is designed to be able to mesh with the engagement teeth 11 of No. 0, and felled wood W is loaded onto a cart 42 which is pulled or pushed behind by this.

The conveying device configured as described above changes the laying length and position of the single track 10 as the location where the timber W is felled changes, and selects an appropriate standing tree T and supports it on this standing tree T. The single track 10 is attached via a device 30 to prevent it from falling sideways, and the single track 10 is connected and extended to a desired location.

When installing the structure, it is only necessary to set the columns upright on the ground and adjust the height to an appropriate height by expanding and contracting the columns, but there is no need to do work such as driving the columns.

Moreover, when changing the position of the laid single track, the attachment of the support device 30 to the standing tree T only needs to be canceled and the attachment to another standing tree T is performed.

As is clear from the above explanation, the conveying device of this invention does not require any driving work into the ground when laying the single track, and instead selects standing trees T at appropriate intervals and attaches supporting devices, thereby supporting the single track being laid. Because of the structure, it is easy to install or extend/change the installation position.
It is convenient to use for transporting wood.
