Description

[Detailed explanation of the idea] The present invention relates to a loading platform expansion device for a transport vehicle.

In other words, it has a transport vehicle structure in which the front door can be opened and closed on the front of the cargo platform.In particular, the front door can be installed with the front door slanted downwards on the front end of the cargo platform. To provide a structure that can be supported so as not to occur and can be suitably implemented with a simple structure.

Next, the embodiment shown in the drawings will be described.

FIG. 1 shows a 1tlb side view of the transport vehicle, and a control section cover 1 is provided on the rear side of the fuselage frame 9 supported by crawlers 8.
0, engine cover 11, stainless steel 7" 12, control lever 13, etc. are installed, and the fuselage frame 9 is installed on the front side of the fuselage.
Loading platform A is installed on the top, but the intermediate part of loading platform A is pivoted by the metal 14 on the fuselage frame 9 so that it can rotate around the fulcrum O, and the operation of extending backward from the rear end side of loading platform A is performed. The lever 15 is removably locked by a hook 16, and the loading platform A can be tilted and dumped using the operating lever 15.

The side gates 4, 4 on both sides of the loading platform A are installed so as to be able to rotate outward, respectively.
Hook parts 5, 5 each having a recess 5a facing diagonally rearward are fixedly attached to the upper part of the front end side of the platform A, and the upper ends on both sides of the front gate 1 can be fitted between the front ends of the side gates 4, 4 in front of the loading platform A. Arms 3, 3 are respectively extended in a direction perpendicular to the front flap 1, and on the inner side of the rear end portions of both arms 3, 3, there is a retaining pin 2゜2 having a head 2a at the tip.
′ sideways and fix each.

On both sides of the loading platform A, hooks 6.6' and supports 7, 7' are provided below the front end of the platform A, projecting forward, respectively. ' is made of a plate and is formed integrally on the upper and lower sides, and the engaging pins 2 are attached to the hook parts 6 and 6' at the front and rear.
A concave groove 6a>6b is formed so that the end portion 1a of the front flap 1 on the arm 3 side can come into contact with the forward protrusion 7a of the supports 7, 7' below the concave groove 6a>6b. to form.

In the figure, 17 indicates a paddy bag.

Therefore, during normal transportation, the front flap 1 with the arms 3 and 3 side facing upward is aligned with the front end of the loading platform A, and
When the engaging pins 2, 2' of the arms 3, 3 are engaged with the recesses 5a, 5a of the hook parts 5, 5, the front part of the loading platform A can be covered, and the loading platform A can be dumped and loaded with earth and sand. When discharging the cargo, lift the operating lever 15 to rotate and tilt the loading platform A around the fulcrum O, and the front gate 1 will rotate using the engagement pins 2 and 2' as fulcrums to discharge the cargo. I can do it.

Also, remove the engaging pins 2, 2' from the hook parts 5, 5, replace the front flap 1 up and down, and remove the engaging pin 2 of the arm 3゜3.
', 2 are engaged with the grooves 6b, 6b of the hooks 6, 6', respectively, and both sides of the end 1a of the front gate 1 are brought into contact with the protrusions 7a, 7a of the supports 7, 7'. , as shown in FIGS. 6 and 7, the front gate 1 can be installed in an inclined state below the front end of the loading platform A, so that, for example, the paddy bag 17 can be prevented from collapsing as shown by the imaginary line in FIG. 6. It can be loaded without any problems.

Note that the engagement pins 2' and 2 are connected to the front groove 6a.

6a, as shown in FIG. 8, the front gate 1 can be installed in a state with less inclination, and the way cargo is placed can be changed.

In this way, the present invention has engagement pins 2 and 2 on the rear end side of the upper end of the front gate 10 for opening and closing the front side of the loading platform A.
' arms 3, 3 are extended, respectively, and hook parts 5, 5 that engage with the engagement pins 2, 2' are fixedly installed on the upper front end sides of both side gates 4, 4, respectively, and Below the front end on both sides of A are the engaging pins 2', hook parts 6, 6' that engage with the 2, and supports 7, on which the end 1a abuts.
7' are provided on the upper and lower sides, and when the front gate 1 is replaced vertically, the front gate 1 can be supported in an inclined state by the hooks 6, 6' and the supports 7, 7'. By engaging the engaging pins 2 and 2' with the hook parts 5 and 5, the front gate 1 can be attached to the front end of the loading platform A in a hanging state so that it can be covered in the same manner as before, and the front gate 1 can be engaged by changing the top and bottom. When the pin 2' 2 is engaged with the lower hook parts 6, 6' and the ends of the front gate 1 are brought into contact with the supports 7, 7', the front gate 1 is tilted downward on the front end side of the loading platform A. The load platform A can be expanded by attaching it to the front flap 1, and the inclination of the front gate 1 allows the loading of, for example, paddy bags without causing the load to collapse, and has the feature that it can be carried out suitably with a simple structure.
