The purpose is to enable safe and effective loading and unloading of long columnar bodies by rotating the support column.

Conventionally, in a transport vehicle for loading and unloading long columnar objects such as logs, a supporting column to prevent the loaded long columnar objects from falling has been installed on the side of several rows of horizontal timbers suspended horizontally on the loading platform on the chassis frame. generally known.

With this conventional device, when loading and unloading, the support columns must be manually removed or attached one by one, which is not only time-consuming and inconvenient, but also causes the support columns to be damaged by the load. Side pressure is applied, making it difficult to hold the support column, and when the support column is removed, the load may fall, resulting in a lack of safety.

On the other hand, according to the invention of this application, the support columns are simply rotated without being removed, so that the cargo can be easily and safely unloaded without causing the cargo to fall.
It is extremely useful.

In the invention of this application, the load is locked so that it cannot be tilted during traveling and transportation, and in order to unload the load, the lock on the opposite side of the loading platform to the direction in which it is tilted is released, and the lock on the tilted side is left as is. Then, while rotating the support column, the tilting hydraulic cylinder in the center is used to overturn the support column.

In the actual device shown in the drawings, the cargo is indicated by phantom lines 31.

In the action explanatory diagrams shown in FIGS. 7 to 9, FIG. 7 shows the support column 2 being held in an upright state, and the loading platform has several rows of horizontal timbers 1 depending on the size of the transport vehicle. One support column 2 for the pillar-hung body is attached to the horizontal timber 1 so that it can rotate about a support shaft 3 as a fulcrum.

A retaining pin 4 is provided at the bottom of the support column 2, and an auxiliary column 5 is provided to adjust the support height.

However, using the support shaft 13 as a fulcrum, the connecting rod 9 is moved inward (indicated by the arrow) in relation to the guiding cam 16, and the wedge piece 7 is removed from the opposing part 6' of the rear grip piece 20.20 of the hook 6. If you let
The hook 6 is attached to the rear gripping piece 20 by the action of the spring 6''.
．． 20 is closed, the front gripping pieces 19 and 19 of the hook 6 are opened, and the engagement pin 4 is released.

In FIG. 9, the support column 2 has fallen due to the inclination of the horizontal rootstock 1, and the cargo 31 shown by the imaginary line is being unloaded.
At this time, the transfer roller 12 provided on the swing arm rod 11 is engaged with the upper part of the guide cam 16 so as not to come off.

The shape of the guide cam 16 is designed to prevent unnecessary loads from being applied to the hook portion and wedge portion due to an increase in the lateral pressure of the load on the support column 2 due to the inclination of the horizontal base 1.
It is designed to correspond to the angle when the horizontal script 1 is tilted.

After unloading a long columnar object such as raw wood, the hydraulic cylinder 1
5, the horizontal script returns from the tilted state to the horizontal position.

If the fallen support column 2 is manually raised upright, it will be in a state where there is no load.

When the support column 2 is stood upright, the relationship between the engagement pin 4 and the hook 6 is as follows: When the support column 2 is manually stood upright using the support shaft 3 as a fulcrum, the retaining pin of the support column 2 is attached to the open hook 6. 4 enters and the protrusion 6'' in the opening of the front gripping piece 19.19 of the hook 6 is pushed by the engagement pin 4, and the upper gripping piece of the front gripping piece 19.19 of the hook 6 is pressed. The lower grip piece moves upward, and the spring 6
"The gripping piece 20 at the rear of the hook 6 works against the engaging pin 4, and at the same time, the contact portion 6 of the rear gripping piece 20.
' is opened, and the wedge piece 7, by the action of the spring 10, plunges into its abutting portion 6', and the support column is held upright.

This holding state is designed and manufactured with sufficient consideration given to the angle, material, etc., so that it can withstand vibrations and other shocks while the transport vehicle is running. This increases the reliability of holding the support column upright, and prevents the support column from falling over.

By adopting the invention of this application, during unloading work, it is no longer necessary to pull out the safety pin or manually hold the upright position by operating a lever, making it possible to operate safely and making it easier to straighten the support column after unloading. This is extremely useful as it can be done in a number of ways.
