Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a securing device for a gate in the body of a dump truck.

Conventionally, the body of a dump truck has columns fixed to each corner of the floor surface, and the side gate and tailgate are secured between each column. When dumping, the opening/closing device at the bottom of the tailgate is opened and the upper stop is secured. The lower part of the tailgate, which was held in place by metal fittings, was open and the cargo was being unloaded.

Recently, dump trucks have been increasingly used as cargo trucks for multi-purpose use, and a flat type body that eliminates protrusions on the body floor during loading and unloading is desired.

However, in such a body, the side gates, tailgate pillars, etc. are all constructed so that they can be extended freely, so there are concerns about the strength when forming the body, and it is difficult to ensure that only one gate is opened and closed. The present invention has been made in view of this problem, and when the side gate, tail gate, and support pillars of the body are erected, the side gate and the support pillars, the tailgate and the support pillars are each firmly bound, It is constructed to ensure the strength of the body and to ensure that only desired gates can be opened and closed.

Next, embodiments of the present invention will be described with reference to the drawings.

A side gate 3 is mounted on a side edge of a floor surface 2 of a body 1 by a hinge 4 so as to be rotatable laterally. Reference numeral 5 denotes a column located at the rear end of the side gate 3, which is attached to the rear edge of the body 1 so as to be able to freely rotate rearward.A bracket 6 is attached to the lower surface of the column, and an outrigger material 7 welded to the back surface of the body 1 Fixed strut mounting member - In the embodiment, each of the above-mentioned brackets 6 is pivotally attached to the hinge 8 so as to be rotatable, and on the other hand, an upper fastener 10 is installed on the upper surface of the bracket 6 to removably pivot the tailgate 9. There is.

Furthermore, the support column 5 can be locked to the side gate 3 by a locking metal fitting 11 attached to the rear of the side gate 3.
By drilling a locking hole in the column 5 at the matching part and inserting the claw piece at the tip of the locking fitting 11 into the locking hole, the column 5 and the side gate 3 are locked. By pulling it out from the locking hole, the lock between the support column 5 and the side gate 3 is released.

Mounting shafts 12 are fixed to both ends of the upper part of the tailgate 9, and the mounting shafts 12 are removably pivoted to the upper stopper 01 mounted on the support column 5, while the lower part is equipped with a mounting shaft 12. 13 is fixed, and the locking claw 14 attached to the rear lower surface of the body that operates automatically or manually, the opening/closing device 16 consisting of the receiving part Muratomi, and the receiving money smelling turtle 3 are attached so as to be engageable. There is.

Next, to explain the operation, ``The side gate 3 is locked to the pillar 5 through the locking metal fitting 111, and the tailgate 9 is engaged at the upper part with the upper locking frame 8 ~ and the lower part is engaged with the opening/closing device 16. As a result, the side gate 3 and the tailgate 9 are tied together, and the body 1' is formed into a box shape with the top open.If a load is loaded on the body in this state, the load will be attached to the tailgate 9. Press down on the pillar 5
Although a force is generated to tilt the side gate 3 in the longitudinal direction, the support 5 and the side gate 3 are made into an integral structure due to the locking metal fitting 11' attached to the rear of the side gate 3, so that the structure can sufficiently withstand the force.

FIG. 3A shows the state when the dump truck is being discharged. When the body 1 is tilted and the locking claw 14 of the opening/closing device 16 of the tailgate 9 is opened, the receiving metal fitting 13 is released from the locking claw 14. Since the tailgate 9 is suspended from the upper stopper Q' on the support column 5, the loaded items are discharged from the lower part of the tailgate 9 which is opened downward.

FIG. 3B shows the opening of the rear part of the body 1, in which the opening/closing device 16 of the tailgate 9 is closed and the receiving metal fitting 13 is secured with the locking pawl 14, and the upper holding metal fitting 10 on the support column 5 is secured.
When the mounting steel 12 is opened, the tailgate 9 moves rearward with the receiving fitting 13 sandwiched between the locking pawl 14 and the receiving member 15 as its axial center, thereby opening the rear part of the body.

At this time, the rear end of the side gate 3 is locked to the support column 5 by a locking metal fitting 11, so that even if a loaded object leans against the side gate 3, a stable state can be maintained without opening outward. Also, when rotating only the side gate 3 laterally, press L.
By pulling out the locking metal fitting 11 provided on the side gate 3, the locking with the pillar 5 is released, and the side gate 3 is released from the hinge 4.
It is possible to spread it laterally around the center, and the side part of the body 1 can be opened. At this time, there is a distance between the placket of the tailgate support column 5, the hinge axis, and the engagement ball of the receiving fitting 13 by the opening/closing device 16 of the tailgate 9, so there is no fear of it falling backward.

FIG. 3C shows a state in which the floor surface 2 is flat. When the opening/closing device 16 at the bottom of the tailgate 9 is closed and the upper metal fitting Q and the locking metal fittings are released,
The lever gate 9 is moved rearward around the receiving shell 13 by the opening/closing device 6, and the pillar 5 is moved from the bracket S and the hinge type part.
Furthermore, the side gates 3 can be rotated laterally from the hinges 4, allowing the floor surface 2 to be placed in a flat state.

As described above, when the side gate, tailgate, and strut are erected on the body, the side gate and the strut can be connected to each other by the locking fitting attached to the rear of the side gate, and the tailgate can be connected to the tailgate by the upper fastening fitting attached to the top surface of the strut. It is useful for improving the strength of the body because it can firmly secure the pillars.

Furthermore, since the axes of the supporting column and the pivot point of the tailgate connected to the opening/closing device are arranged so that their axes are separated from each other, the tailgate does not open even when the side gate is opened. The locking metal fittings and upper locking metal fittings that lock the gates have their operating parts on each gate side, so the other gate will not be opened unexpectedly and only the desired gate can be opened with certainty. .
