A hook member 7 having a hook 72 is provided.

(Operation and Effect) When the lifting frame 3 rises, the container is also supported by the support frame and rises at the same time, and while the container is rising, the upper edge of the container is caught on the hook member 7, and the upper edge of the container is hooked together with the lifting member 6. 7 also rises.

Therefore, when transporting a container on a transport vehicle,
The upper edge of the container is hung on a hook member 7,
It won't fall.

As the lifting frame 3 moves up and down, the hook member 7 automatically hooks onto the upper edge of the container, so there is no need to manually operate the hook member 7, and the hook member 7
There is no need to worry about forgetting to hang it on the container.

(Example) Fig. 1 shows a container transport vehicle, and Fig. 5 shows a container.

Container 9 is made of synthetic resin and has a height of approximately 100 cm and a diameter of approximately 50 cm.
The container 9 is formed into a cylindrical shape with a diameter of 1 cm, and the lower part gradually reduces in diameter to form a tapered part 92, and a short upward circumferential wall 91 protrudes from the upper edge of the container 9.

The transport vehicle is equipped with a lifting frame 3 on a trolley 1 so that it can be raised and lowered,
A pair of support members 4, 4 are rotatably supported on the elevating frame 3 in a substantially horizontal plane.

A short pin 24 is fixed to the protruding end of the piston rod 23 perpendicularly to the rod 23, and a pair of support plates 33, 33 are pivoted downward at both ends of the pin 24.

The lower ends of the support plates 33, 33 are pivotally connected to the elevating frame 3. In the embodiment, the support plate 33 also serves as a connecting member that connects the piston rod 23 of the cylinder 21 and the lifting frame 3.

A body support device 5 for the container 9 is provided at the lower part of the lifting frame 3, and a receiving plate 31 is provided at the front of the lifting frame 3 to prevent the container 9 from falling backward.

The trunk support device 5 has a U-shaped support frame 32 which is fitted within the U-shaped frame 11 of the truck 1 and is horizontally protruded, with arms 36 and 36 sandwiching the container 9 on both sides of the support frame 32. , 36, supporting members 4, 4 are pivotably supported in a substantially horizontal plane.

In the embodiment, the support member 4 is pivoted within the support frame 32 so as to rotate slightly downward.

Each support member 4, 4 is attached to a lower tapered portion 92 of the container 9.
It is formed by curving a tube or plate material with a length of a little less than 1/3 of the outer circumference of the container in accordance with the curvature of the tapered part, with the recessed sides facing each other, and the entire length of the recessed side is the container. It serves as a receiving part 41 for.

A rib 42 is provided at the center of the support member 4 and projects outward, and the rib 42 is rotatably fitted into a pivot pin 38 provided at the tip of the arm 36.

A spring 34 is connected to the support member 4 to bias the member 4 in the outward rotation direction. Although the spring 34 has sufficient force to bias the support member 4 outward, it does not have the force to push the container forward when the container 9 is held between the support members 4 as described later.

A support member stopper 35 is provided at the tip of the arm 36 for abutting against the rib 42 of the support member 4 to restrict the range of outward rotation of the support member 4.

As shown in FIG. 2, when both supporting members 4, 4 are in contact with the stopper 35, the distance W between the inner ends of the supporting members 4, 4 is smaller than the minimum diameter of the tapered portion 92 of the container 9.

Abutments 37, 37 are formed on the U-shaped support frame 32 to restrict the range of inward rotation of the support members 4, 4.

The center P of the imaginary circle C passing through the receiving parts 41, 41 of both the supporting members 4, 4 in a state where both the supporting members 4, 4 are in contact with the abutments 37, 37 is the pivot pin 38 of the supporting members 4, 4. , 38.

Note that the support members 4, 4 are directly attached to the U-shaped support frame 32.
It is also possible to use the U-shaped support frame 32 as a stop for restricting the inward rotation of the support members 4, 4.

An upper edge support device 8 is provided at the upper end of the vertical column 12 of the truck 1 to lock the upper end of the container 9 and prevent the container 92 from falling forward.

The upper edge support device 8 has an elevating member 6 formed by bending a metal plate into a U-shape, and is arranged on the vertical column 12 so that it can be raised and lowered, and both bent pieces 61, 61 of the elevating member 6 are connected to the support plate of the elevating frame 3. Cover 33,33.

A pair of rollers 62, 63 are freely rotatably supported on each bending piece 61, 61 with supporting plates 33, 33 in between, and a stopper 65 for an elevating member is extended by extending the axis of one roller 63 at the rear. The stopper 65 is brought into contact with a contact surface 16 formed on the vertical column 12, in the embodiment, the upper end surface of the vertical column 12 to prevent the lifting member 6 from falling.

A front roller 62 provided between the bent pieces 61, 61,
62 is attached at a lower position than the other rear roller 63.

The center of gravity of the elevating member 6 is located forward of the width center of the support plate 33, and therefore the front and rear rollers 62, 63 are always in contact with the support plate 33.

Swing prevention members 64, 64 are provided on the inner surface of the bent piece 61 above the front roller 62 and below the rear roller 63.
will be provided. The rocking prevention members 64, 64 are the third
When an upward force is applied to the front part of the elevating member 6 as shown by arrow A in the figure, it engages with the support plate 33 in a biting direction and moves up and down together with the support plate 33.

A hook member 7 formed by bending a metal rod into an inverted L shape is arranged at the center of the front surface of the lifting frame 3 so that its height can be adjusted by a clamp device 71. A downwardly directed claw piece 72 is formed at the bottom.

The stopper 65 of the lifting member 6 is connected to the vertical column 1 of the truck 1.
2 and the elevating member 6 is in the lowered position, the hook member 7 is moved so that the lower end of the claw piece 72 of the hook member 7 is at a position slightly higher than the height of the upper edge of the container on the floor surface. Adjust the height.

Then, with the lifting frame 3 lowered, the cart 1 is pushed toward the container 9, the tips of both supporting members 4 are placed on the lower part of the container, and the supporting members 4, 4 are moved against the spring 34 by the arm 36. , 36.

As the support members 4, 4 rotate, the receiving portion 41 on the support member 4 gradually follows the lower peripheral surface of the container 9.

When the support members 4, 4 rotate inward to the maximum, the support member 4 follows the circumferential surface of the container, and the center P of the virtual circle C passing through the receiving part 41 is a straight line L passing through the center of rotation of the support members 4, 4. Therefore, the axis of the container, that is, the center of gravity is also inside the line L.

By stepping on the hydraulic pump 22, the piston rod 23 of the hydraulic cylinder 21 is projected upward, and the elevating frame 3 is raised via the support plates 33, 33.

When the lifting frame 3 is raised, the tapered part 9 at the bottom of the container
2, the weight of the container is applied to the support members 4, 4, but as mentioned above, the center of gravity of the container is located inside the straight line L passing through the center of rotation of the support members 4, 4. Therefore, the support member 4 does not rotate to the outside of the arms 36, 36.

The reason for this is that if the center of gravity of the container is located on a straight line passing through the centers of gravity of both support members 4, 4,
The load acts equally forward and backward from the center of rotation of the supporting members 4, 4, and the supporting members 4, 4 remain stationary without rotating inward or outward. In the case of this application, the supporting members 4, 4, the center of gravity of the container 9 is located inside the straight line L passing through the center of rotation of the support members 4, 4, so that the force R1 pushing the support members 4, 4 outward is This is because the force R2 pushing the inner side becomes larger.

The support members 4, 4 enter between the arms 36, 36 at the maximum and do not rotate inward any further, so that the container rises while being held by the support members 4, 4.

As mentioned above, the support members 4, 4 rotate inward slightly downward, so when the container is held by the support members 4, 4, the container tilts slightly backward and hits the abutment plate 31 of the lifting frame 3. It rises in a cascading state.

When the lifting frame 3 starts to rise, even if the support plate 33 rises, the lifting member 6 of the upper edge support device 8 is moved by the rollers 62, 6.
3 only rotates in contact with the support plate 33, and the height position of the elevating member 6 does not change.

As the container 9 rises, when the upper end of the container hits the horizontal portion 73 of the hook member 7 of the upper edge support device 8 and an upward force is applied to the front part of the elevating member 6, the swing prevention member 64 of the elevating member 6 , 64 strongly press against the support plate 33 so as to bite into the support plate 33 and the lifting member 6.
rises in unison. When the container 9 rises from the floor, the cart 1 is pushed to the desired location to move the container.

Even if the trolley 1 tilts back and forth due to unevenness of the floor, the lifting frame 3 is provided with a receiving plate 31 that prevents the container 9 from falling backward, and an upper edge support device is installed inside the upper edge of the container. Since the claw pieces 72 of No. 8 are inserted, there is no risk that the container 9 will fall back and forth.

When moving the container 9 to a target location and lowering the lifting frame 3, the upper edge support device 8 supports the support plate 3 of the frame 3.
It descends together with 3.

While the elevating member 6 is descending, the stopper 65 hits the contact surface 16 at the upper end of the vertical column 12 and is caught, and the descending of the member 6 is stopped, but the elevating frame 3 further descends until the bottom of the container is on the floor. ground to the surface.

When the cart 1 is pulled in the direction of separating it from the container while the container 9 is in contact with the floor, the supporting members 4, 4
is opened outward by the force of the spring and being pushed by the container, allowing the container to be removed from between the arms 36, 36.

Containers that can be transported by the transport vehicle of the present invention are not limited to those that have a tapered portion 92 whose lower part is reduced as described above, and as shown by the two-dot chain line in FIG. Support members 4, 4 are attached to the trunk.
It is also possible to carry items with protruding ribs 93 that can be hooked on.

In carrying out the present invention, as shown in FIG. It can also be used by mounting it on a lift. In this case, the forklift main body becomes the truck 1.

Further, the arms 36, 36 at both ends of the U-shaped frame 32 can be separated and used by directly fitting the arms 36, 36 into the forks of a forklift.

Further, as shown in FIG. 6, a plurality of ribs 4 are provided on the support member 4.
It is also possible to form the receiving part 41 by attaching 1a on the support member 4 along the curvature of the tapered part 92 of the container 9.

Furthermore, the present invention is not limited to the above configuration, and various modifications can be made within the scope of the claims for utility model registration.
