Description

[Detailed explanation of the invention] This invention relates to the structure of the rear cover of power transport vehicles used for transport work, especially in narrow construction sites where dump trucks cannot enter, mountainous areas, wet fields, etc. ,
The purpose is to facilitate the loading and unloading of transported items.

This invention is based on a power transport vehicle which is provided with a column 3 for attaching a rear cover 6 to the rear corner of the loading platform 2, in which a guide cylinder 4 is vertically disposed at the rear corner of the loading platform 2, Further, an insertion part 3a is formed at the base end of the column 30 to be removably fitted into the guide cylinder 4, and bottle holes 3b and 4a are provided in alignment with the insertion part 3a and the guide cylinder 4. With,
Pins I are removably inserted into the pin holes 3b and 4a, and the column 3 is fixed in an upright state with the pin I inserted, and the side cover 5 and the side cover 5 are connected to the side of the column 3. A protrusion 3d having a contact surface 3c is provided, and a rear cover 6 is provided at the upper end of the column 3.
A pivoting part 3e that can be freely attached to and detached from the pin 10 provided at the upper end is provided, and the rear lid 6 is supported so as to be openable and closable around the pivoting part 3e, and the insertion part 3a of the columnar body 3 is The rear lid attachment structure is characterized in that the pillar body 3 and the rear lid 6 are detached from the loading platform 2 as a unit when they are removed from the guide tube 4.

In the figure, 3 indicates a hydraulic cylinder device for tilting the loading platform 2, and 9 indicates a hydraulic cylinder device 8 for tilting the loading platform 2.
A locking device 11 is a hinge of the side lid 5, which releases the locking of the rear lid 6 when the rear lid 6 is tilted.

Note that the shape of the pivot portion 3e is a cutout hole so that the rear end 6 can be attached to and detached from the column 3 independently.

In this invention, when a desired material such as earth and sand is loaded on the platform 2 of the Itapira complete power carrier 1 or dropped from the platform 2, the side lid is placed upright on the platform 2 depending on the nature of the material to be transported. 5 and the rear lid 6 are all opened, or only the rear lid 6 is opened.

That is, as is well known, the base end of the side cover 5 is pivotally connected to the loading platform 2 by a hinge 11, so that by removing a latch (not shown) at the top thereof, it can be opened to hang below the loading platform. The insertion part 3a can be pulled out from the guide cylinder 4 by removing the pin 1 which is the fixing means for the column 3, which is suspended by the upper pivot part 3e of the rear cover 6. Therefore, the rear cover 6 can be removed from the loading platform 2 together with the column 3, or after the loading platform 2 is slightly tilted by the hydraulic cylinder device 8,
The locking device 9 of the rear lid 6 is automatically removed, and the rear lid 6 is suspended from the pivot joint 3e, so that only the rear lid 6 can be pivoted without removing the column 3 from the loading platform 2. It can be opened and closed centering around part 3e.

Further, the rear cover 6 can be removed from the column 3 if necessary.

Next, when loading and transporting objects, a protrusion 3d is provided on the side surface of the column 3 that stands up at the rear corner of the loading platform 2,
In addition, since the same portion has a contact surface 3c that comes into contact with the side cover 5 when the side cover 5 is erected, the standing state of the side cover 5 can be made stable.

As described above, according to this invention, the rear cover can be removed as desired, and it can also be opened and closed without removing it, making it possible to handle the rear cover in a way that suits the work conditions. This has the effect of making it easy to take things in and out of the container.
