Description

[Detailed description of the invention] (a) Industrial application field This invention relates to an improvement of a loading device disposed on the loading platform of a forestry transport vehicle for loading long wood onto the loading platform.

(B) Prior art There is a prior art similar to the above-mentioned loading device, as seen in Japanese Utility Model Publication No. 54-18967, in which a loading device is installed along the rails of a frame that stands above the loading platform. A lifting device that can move back and forth is installed, and when loading cargo, the vehicle is moved and adjusted so that the cargo to be loaded is located directly below the rear end of the rail, and the cargo is first placed vertically using the lifting device. The device is configured to lift up the load, then move the lifting device in the load lifting state forward, and lower the lifted load at a required position.

(c) Problems to be solved by the invention As is clear from the above points, in conventional loading devices, the lifting device is a hoist, and the cargo cannot be lifted unless it is positioned directly below the rail. However, it is inconvenient that it cannot be used for tasks such as pulling long pieces of wood or the like that are located far away from the vehicle body towards the vehicle and then continuously pulling them onto the loading platform for loading.

Therefore, the present invention was implemented with the aim of eliminating the above-mentioned inconveniences of conventional loading devices, and it is a loading device that can continuously load long pieces of wood, etc. onto a loading platform from a location away from the vehicle. This is what we provide.

(d) Means for solving the problem In order to achieve the above-mentioned object, the present invention has an operating section 1 installed at one end of the upper part of the frame F supported by the traveling devices 3, 3 on both sides, and a In a wood loading device for a forestry transport vehicle A, in which a loading platform 2 is extended toward the other end, a winch 6 is provided below the loading platform 2, and a sheave S for guiding a wire 5 is provided at the front of the loading platform 2. , a gate frame 11 equipped with a pulley 8 through which a wire 5 that can be pulled in and pulled out by the winch 6 is inserted is erected so as to be able to slide freely across both sides of the loading platform 2, and the gate frame 11 is A fixing means for fixing to the loading platform 2 is provided so as to be freely fixed and released at any position.

(e) Effects Since the present invention is a loading device having the above-mentioned configuration, a long piece of wood or the like located far away from the transport vehicle A is connected to the tip of the wire 5 fed out from the winch 6.

At this time, the wire 5 paid out from the winch 6
is inserted into the pulley 8 suspended below the gate frame 11, so that it is drawn out obliquely upward.

At this time, the gate frame 11 is immovably fixed to the loading platform 2 by a fixing means.

In this state, when the tip of the long piece of wood rides on the tip of the loading platform 2 while operating the winch 6 and pulling in the wire 5, the winch 6 is temporarily stopped, and then the fixing means fixing the gate frame 11 to the loading platform 2 is removed. When the winch 6 is released and the winch 6 is further activated to continue winding up the wire 5, a long piece of wood or the like comes into contact with the pulley 8 of the gate frame 11, and after that,
The gate frame 11 itself, together with a long piece of wood, etc., slides and moves toward the front side of the loading platform 2 by the action of the winch 6.

As mentioned above, the pulling and loading of long timbers is carried out in a continuous operation, and since the winch 6 is installed below the loading platform 2, the center of gravity of the transport vehicle itself is lowered to improve stability. It is possible to exert a strong pulling and loading force, and there is no restriction on the loading movement path or the loading space of the long wood on the loading platform 2, making it possible to work extremely conveniently.

(f) Examples Hereinafter, embodiments of the present invention will be described in detail with reference to drawings of specific examples.

A forestry transport vehicle A is equipped with an operating section 1 at one end of the upper part of a frame F, and has a loading platform 2 extending from the rear of the operating section 1 toward the other end, and further supports the frame F at the lower part. A winch 6 is provided below the loading platform 2.

The pillars 10 and 10a forming the gate frame 11 are
Each of them is erected in the front and rear, spanning the loading platform 2, and has a substantially triangular shape when viewed from the side, and its base wraps around the side edges of the loading platform 2 to support it so that it can slide, and can also be moved to any position on the loading platform 2. It is provided so that it can be fixed with a fixing means such as a pin, and when sliding with respect to the loading platform 2, it can be slid by removing the fixing means such as a pin.

The wire 5 wound around the winch 6 passes below the loading platform 2, is wound around the sheave S, passes through the pulley 8 fixed at the center of the upper part of the gate frame 11, and passes through the far end of the wire 5. It is provided so that it can be freely combined with the shaku lumber 4.

The gate frame 11 can be fixed manually or with a winch 6 by removing and releasing fixing means such as pins.
The gate frame 11 is moved to the side of the operating section 1 by the action of the gate frame 11, and the gate frame 11 also serves to protect the operator.

Since this invention has the above configuration, it is used as follows.

The gate frame 11 is fixed to the tip of the loading platform 2, and the drawn end of the wire 5 is connected to the long wood 4 to be transported.Then, the winch 6 is operated to move the long wood to the tip of the loading platform 2 of the transport vehicle A. 4, and further operates the winch 6 to pull the long timber 4 until it rests on the upper surface of the loading platform 2.

If the long timber 4 rides on the loading platform 2, the gate frame 11 is released from its fixation so that it can slide, and then the winch 6 is activated to move the long timber 4 onto the loading platform at the same time as the gate frame 11. 2 to the operation section 1 side.

(g) Effects of the device As is clear from the above explanation, the loading device of the present invention has an operating section 1 installed at one end of the upper part of the frame F supported by the traveling devices 3, 3 on both sides, and an operation section 1 installed from the rear of the frame F. In a wood loading device for a forestry transport vehicle A, which has a loading platform 2 extending toward the other end, a winch 6 below the loading platform 2, and a sheave S for guiding a wire 5 at the front of the loading platform 2,
A gate frame 11 equipped with a pulley 8 through which a wire 5 that can be freely drawn in and pulled out by the winch 6 is inserted.
are erected so as to be able to slide freely across both sides of the loading platform 2, and the gate frame 11 is attached to the loading platform 2.
Since the fixing means for fixing to the vehicle A is provided so that the fixation can be released at any position, by hoisting the winch 6, the long lumber 4 located far away from the transport vehicle A can be pulled in, and the upper part of the loading platform 2 can be pulled up. Moreover, it is possible to completely load the long timber 4 onto the top of the loading platform 2 while sliding the gate frame 11 by hoisting the winch 6, allowing continuous and efficient loading work. There are advantages.

In addition, since the winch 6 is placed below the loading platform 2, the center of gravity of the transport vehicle itself is lowered, and the lumber pulling and lifting force can be exerted strongly and stably. It has the advantage of being able to work conveniently without placing restrictions on routes or loading space.
