Abstract

PURPOSE:To make the relative movement between a transport vehicle and a load smooth by providing a roller adapted to roll longitudinally on a turn-table on an auxiliary trailer. CONSTITUTION:A roller 13 adapted to roll longitudinally is provided on the top of a turn-table 12 provided on a carrier 10 of an auxiliary trailer 5. When a load is performed, a load 4 is brought from the rear thereof and the front end thereof is placed on the turn-table 12. A roller 13 positioned thereunder enables the loading simply by pushing it forward from the rear thereof, hence saving labor and making the work safe. Also, the use of a type roller 13 divided into several sections horizontally permits the loading sequentially shifting from the end thereof with only a fixed part of the roller, rolling.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary trailer towed by a transport vehicle for loading long objects, and a turntable for towing in the transport vehicle installed on the platform of the auxiliary trailer.

For transport vehicles used for cutting wood, etc., an auxiliary trailer is used when loading long items.

By the way, when using such an auxiliary trailer,
Since the seed material is long, it has a large weight and length, making it very difficult to dig into it.

Therefore, this invention uses a roller on the top surface of the turntable installed on the loading platform of the auxiliary trailer, and by placing the front end of the seed material on this roller, it is possible to load it by simply pushing it forward. This is intended to save labor.

Additionally, since the tow point of the auxiliary trailer is generally offset to the rear of the position of the turntable installed on the transport vehicle, the tow line and line of action, which are aligned when traveling straight, become misaligned when turning. In order to absorb the deviation, the transport vehicle and the seed material or auxiliary trailer must move relative to each other, which requires a structure, and the vehicle itself pitches and rolls violently, making it unstable and making loading difficult. There were drawbacks such as damage. In such cases, if you use the rollers mentioned above on the turntable on the auxiliary trailer,
This allows for smooth relative movement between the transport vehicle and the cargo.

Examples of the present invention will be described below with reference to the drawings.
In the accompanying drawings, FIG. 1 is a side view of a carrier equipped with the present invention, FIG. 2 is a plan view, FIG. 6 is a grenade view of the turntable, and FIG. 4 is a longitudinal sectional view.

The transport vehicle has a loading platform 2 mounted on a crawler-type traveling device 1, and the front portion of the loading platform 2 serves as a control section.

The loading platform 2 has a flat surface, and is further equipped with a turntable 4 near the rear thereof.

When towing the auxiliary trailer 5, the front end of the traction rod 7 of the auxiliary trailer 5 is pivotally connected to the pitch mechanism (towing point) B provided at the rear end of the loading platform 2 with a pin 8. In addition, traction rod 7
A rolling absorption mechanism 9 is inserted in the middle.

In addition to the above-described configuration, the auxiliary trailer 5 has a loading platform 10 formed at the rear end of the traction rod 7, and wheels 11.
11 is installed.

A turntable 12 is also installed on the loading platform 10, and a roller 16 that can be moved forward and backward is buried in the upper surface of the turntable 12, and the surface of the roller 16 is exposed.

With this configuration, the stowage 14 is loaded so as to be passed between the turntable 4 of the carrier vehicle and the turntable 12 of the auxiliary trailer 5. In addition, regardless of which turntable 4.12, if bar-shaped cargo collapse prevention bodies 15.16 are placed against both ends of the turntable 4.12, the turntable 4 and stowage 14 on the transport vehicle side are Lightly tie them with wires 17 or the like so that they cannot move relative to each other.

By the way, in the above explanation, the roller 16 is connected to the auxiliary trailer 5.
This is an example in which the turntable 12 is provided on the turntable 12 of
A similar effect can be obtained when both turntables 4 and 2 are provided (in the latter case, it is necessary to strengthen the binding between one of the turntables 4 and 12 and the stowage 14).

As described above, this invention is provided with rollers 16 that move in the front and back direction on the upper surface of the turntable 12 installed on the loading platform 10 of the auxiliary trailer 5. When loading, bring the stowage 14 from the rear and place its front end on the turntable 12. Since there is a roller 16 underneath, loading is possible by simply pushing from the rear to the front. It is very labor-saving and also safe. At this time, if the roller 16 is of a type that is divided into several parts in the left and right direction, only a certain part of the roller 13 (only on the lower side of the stowage 14) needs to roll. It is possible to load from one end to the other.

In addition, even if the turntable 4 and the traction point B of the transport vehicle are offset in the front and back, the transport vehicle and the loading point due to the misalignment between the line of action and the traction line L during turning may occur.
4 or the auxiliary trailer 5.
3 easily absorbs by rolling. In this respect, in the conventional system, in order to transmit the traction force from the turntable 4 to the rear turntable 12 (auxiliary trailer 5) via the stowage 14, each turntable 4.12 and stowage 14 are tightly tied together. As a result, during relative movement, a large force acts on the stowage 14, damaging it and causing severe vibrations, but according to the present invention, such problems do not occur. In this effect as well, the split roller 13 described above exhibits finer adaptability.

In addition, since the traction rod 7 can be a fixed type that does not need to be expanded or contracted, it has the advantage that it can exhibit good traction force and can be manufactured at low cost.
