Abstract

PURPOSE:To eliminate the necessity for providing a different driving gear driving a discharge plate or the like, by utilizing telescopic action of a telescopic frame in a container handling vehicle. CONSTITUTION:Under a condition for mounting a container C on a car bed 1, if a rotary shaft 23 of an intermediate sheave 19 is fitted to a hole of a bracket 22 to contract a telescopic cylinder 8, the container C is slid rearward in accordance with contraction of a telescopic frame 4. In short, the sheave 19 is slid forward to a long hole 47 in a bottom part of the container C by relative motion between the bed 1 and the container C. By moving action of this series, a sliding amount is further amplified through wires 15, 16 to slide a discharge plate 13 to the rear. To unload the container C onto the ground, the shaft 23 of the sheave 19 is pulled out of the hole of the bracket 22, and then if the cylinder 8 and a lift cylinder 9 are suitably telescopically operated, the frame 4 is turned rearward with a connection part 5 as the center, and the container C is slid on a guide roller 10 and unloaded onto the ground.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention utilizes the longitudinal sliding movement of an extensible frame constituting a container loading/unloading device of a container cargo handling vehicle, and eliminates the need for a separate drive device to remove a discharge plate provided on a container. Or it relates to something that can drive a canopy or the like.

Hereinafter, the first embodiment of the present invention will be explained with reference to FIGS. A telescopic frame 4 is bendably connected 5 to the tip of 1. j, the telescopic frame 4 is a guide member 6
A lift cylinder 9 is connected between the 5-shaped sliding member 7 chassis 1 and the telescopic frame 4, and the telescopic frame 4 is bent backward or undulated by the telescopic operation of the lift cylinder 9, as will be described later. Frame 2 and Isshinto ηt can be tilted backwards.

A guide roller 10 is rotatably supported coaxially with the pivot 3s of the undulating frame 2, and this guide roller 10
7 hooks 11 are fixed to the upper end of the telescopic frame 4, that is, the upper end of the sliding member 7. The engaging pin 12 can be engaged and disengaged.

A3 By the way, inside the container 0, a 6" discharge plate 1 which is in contact with the inner wall of the container 0 is installed so as to be able to slide back and forth on the container floor plate a', and on the lower surface of this discharge plate 13 there is a locking piece 14.
is installed protrudingly.

On the other hand, to explain the driving means, the locking piece 1
One end of a wire 15, 16 is fixed to the front and rear surfaces of the container 4, and this wire 15 connects a sheave 18 which is pivotally supported 17 at the front bottom of the container and an intermediate sheave 19 which is locked 26 so as to be slidable back and forth. After hanging, the wire 16 is fixed at a proper place on the bottom of the container 0, and the wire 16 is fixed at a position m on the bottom of the container a after hanging the sheave 21 and the intermediate sheave 19, which are pivoted 20 on the rear bottom of the container. has been done.

Thus, a bracket 2 is installed on the upper surface of the undulating frame 2.
2 is provided in a protruding manner, and a rotating shaft 26 of the intermediate sheave 19 can be fitted into a hole bored in this bracket 22.

In other words, when the rotating shaft 23 is fitted into the hole of the bracket 22, the intermediate sheave 19 is pivoted 26 on the bracket 22. Note that 24 is a pair of left and right rear doors of the container C; It is pivoted 25 to the rear end side wall and can be opened and closed as appropriate. Further, 47 is a long hole bored in the bottom of the container 0, and the rotating shaft 26 of the intermediate sheave 19 is connected to the long hole 47.
7, and allows the intermediate sheave 19 to slide back and forth.

Next, the operation of the first embodiment of the present invention will be explained. As shown in FIG. When the telescopic cylinder 8 is then contracted, the container 0 slides rearward as the telescopic frame 4 contracts.

In other words, due to the relative movement between the chassis 1 and the container 0,
The intermediate sheave 19 slides forward with respect to the elongated hole 47 in the bottom of the container 0. This series of movements causes the wire 15.
16, the amount of sliding is further increased, and the discharge plate 16 slides rearward as shown in FIG.

Therefore, even in a place where the container O cannot be tilted, the contents of the container O can be discharged.Furthermore, in order to return the discharge plate 16 to the forward position, the above procedure can be performed in reverse.

Next, in order to unload the container C from the chassis 1 to the ground, the lift cylinder 9 is extended and contracted appropriately, and the telescopic frame 4 rotates rearward around the connection 5, and the container 0 slides on the guide rollers 10 by its own weight. It can be unloaded to the ground while

Furthermore, in order to place the container 0 on the vehicle platform 1 from the ground, the above-mentioned procedure may be reversed. .

Next, a second embodiment of the present invention will be explained with reference to FIGS. 4 and 6. On the chassis 1, there is a undulating frame 2 similar to that of the first embodiment. Telescopic frame 4. Lift cylinder9. Container 0 is loaded.

By the way, to explain the driving means, a bracket 26 is protruded from the upper surface of the guide member 6, a sprocket 27 is pivotally supported by a vertical axis on one side of the center bottom surface of the container C, and At the bottom of the front end of the container 0 in front of the block 27, two sets of block brackets 28, 28 are supported by a horizontal shaft 29.
has been done. Furthermore, a sprocket 60 is pivotally supported 61 at the front end portion of the container C above the sprocket 28 by a shaft in the front and rear direction, and the sprockets 27, 28
．． A chain thread 62 is suspended between 28 and 30.

Both ends of the chain string 62 are fixed to a locking piece 63, and a bottle 64 can be fitted across a hole drilled in the locking piece 66 and a hole drilled in the bracket 26. There is.

On the other hand, a small pinion 65 is fixed to the sprocket 30 on the same shaft 61, and a large pinion 38 fixed to the front end of a rotating shaft 67 of the canopy 36 is screwed to the small pinion 65. Also, sprocket 69 coaxial with sprocket 6°
A small pinion 43 similar to that described above is suspended between the sprocket 41 which is pivotally supported at a symmetrical position.
In addition, a large pinion A7 screwed into the small pinion 43 as described above is supported by a shaft 45, and roughly on the shaft support 45,
A canopy 46 is fixed. Thus, the canopy 36,
46, the upper part of the container C can be opened and closed.

Next, the operation of the second embodiment of the present invention will be explained. As shown in FIG. , the pins 64 are fitted into both holes, and the locking pieces 66 are fixed to the bracket 26, that is, to the vehicle chassis 1 side. Thereafter, when the telescopic cylinder 8 is contracted, the container a slides rearward as the telescopic frame 4 contracts. Due to this series of actions, the container C and the bracket 26 move relative to each other, and as a result, the copper strip 62 is pulled, and the sprocket 60
rotates counterclockwise. In other words, the rotation of this sprocket 60 passes through the small pinion 35° and the large pinio b, and then the canopy 60.
6 in a clockwise direction.

On the other hand, simultaneously with the rotation of the sprocket 60, the sprocket 41 is rotated clockwise by a sprocket 69 coaxial with the sprocket 30, and the canopy 46 is rotated counterclockwise. In this way, the canopies 36 and 46 are rotated to open the upper part of the container 0.

Moreover, to close the upper part of the container C, the above-mentioned procedure may be reversed.

Further, in order to unload the container 0 from the vehicle platform 1 to the ground and vice versa, the same procedure as in the first embodiment described in Section 1lff may be used.

As described above, according to the present invention, it is possible to drive the discharge plate, canopy, etc. inside the container by utilizing the telescoping action of the telescoping frame of the container cargo handling vehicle, without providing a separate drive device to the container.

Therefore, the container is made lighter and the cost is reduced.
