If you look at the bottom of the storage box to store the ladder and to prevent the shaking slats and the stored ladder is fixed as a pin so as not to be released during the movement, and the locking step at the tip so that the ladder can be caught in the connection groove of the loading box to the ground It forms a structure to be formed.

However, when the ladder is stored, the entire surface of the edge portion moves to the inner surface of the partition, so it requires a lot of force and at the same time there is a problem in that foreign matters such as dirt accumulate and noise that causes discomfort and discomfort. When the down to the ground and connected to the loading box and the ladder completely separated from within the partition and then lifting the jamming jaw of the front end to the stacking groove to be placed on the connection groove, there was a problem that the installation work is cumbersome and requires a lot of work manpower.

The present invention has been proposed to improve the above problems in the prior art, it is possible to facilitate the operation for loading or unloading heavy equipment by fixing the inclined plate that can be folded by the cylinder operation to the rear end of the trailer. There is a purpose.

In addition, another object of the present invention is to provide a structure capable of easily varying the separation interval between the inclined plate to enable the loading of several kinds of heavy equipment of different sizes.

The purpose of the inclination plate of the trailer is installed on both sides of the inclined plate for heavy equipment loading on the rear end side of the trailer when loading or unloading heavy equipment to form a predetermined inclined surface, the inclined plate is to be folded in two sets to be folded It is connected to the rear end of the trailer while being connected to be fixed rotatably, one end is provided with a rotation cylinder for transmitting the rotational force about the rotation shaft; The fixed bracket is connected to the variable cylinder for varying the distance between the two inclined plate is possible to achieve through the heavy equipment loading inclined plate of the trailer, characterized in that it is provided to enable the left and right movement of the inclined plate along the rotating shaft.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, referring to the technical configuration of the trailer according to the present embodiment, as shown in Figure 1, the mounting portion (2) for safely supporting the large heavy equipment installed and mounted at a low height from the ground, and based on the mounting portion (2) The front side is generally composed of a front deck portion 3 having a height higher than the mounting portion 2 so as to be connected to the tow vehicle, and a wheel portion 4 supporting the trailer 1 on the rear side to enable safe driving. In the trailer 1 structure, the rear end of the trailer 1 has two sets of folding structures 10a and 10b, and the inclined plate 10 which is rotatable about the pivot shaft 11 is provided in a vertical form. .

The inclined plate 10 is connected to the stop portion by the folding shaft 15, of which the rear end side inclined plate 10b, as shown in Figure 2, the support wire 16 via the guide roller 18, the trailer mounting portion It is connected from the (2) side, so that the rear end side inclined plate (10b) can form a proper inclined surface during rotation, and the connecting ring (17) is provided to prevent flow during storage, and the folding shaft of the front side inclined plate (10a) (15) Inside the site, the inclination pedestal 19 of the form shown in FIG. 7 is freely hinged 20 to be pivoted so as to support the load at the interruption of the inclination plate 10 while descending by its own weight during installation.

In addition, a rotation cam 12 is installed at the center of the length of the rotation shaft 11, and a rod 13a of the rotation cylinder 13 is connected to and mounted on the rotation cam 12 as shown in FIG. 4. It was configured to receive.

In addition, each of the variable cylinders 14 for varying the distance between the two inclined plates 10 is connected to both of the inclined plates 10 in the rotation cam 12, so that the rotating shaft 11 is rotated as shown in FIG. According to the configuration of the inclination plate 10 can be adjusted.
