The pressing hydraulic cylinder device (81) includes a rod member (6).
However, as shown in FIG. 5 and FIG. 6, the contact part (62) on the rod member (6) has the receiving part (1) on the carriage (1).
The rod member (6) is prevented from sticking out because it rides on (0). Therefore, the working oil flows into the lifting / lowering cylinder device (23) to eject the piston rod (85) having a large load and raise the lifting / lowering base (2). When the lifting table (2) is raised by continuing the stepping operation of the hydraulic pump (92), the contact part (62) on the rod member (6) floats above the receiving part (10), so the working oil is pressed. It flows into the hydraulic cylinder device (81) for use to project the rod member (6) relative to the tilting post (3). This operation is a lift
Since it follows the rise of (2), it seems as if only the tilting post (3) rises while the hitting part (62) remains on the receiving part (10).

The working oil from the subsequent hydraulic pump (92) flows only into the lifting cylinder device (23) and raises the lifting platform (2). When the check valve (97) on the lift table (2) crosses the cam plate (36) on the carriage (1) due to the further lift of the lift table (2), the pressing hydraulic cylinder device (81) The working oil is prevented from flowing out, and the upper claw (42) is locked in the closed state.
Further, the hanging piece (52) is also locked in a state of being caught by the lower edge (202) of the container. Therefore, the container can be reliably held along the tilting post (3) in any posture of the reversing frame (25), that is, the container (200).

When the check valve (97) is omitted, it is shown in FIG.
As shown in 0, the reversing frame (25) is reversed by the manual reversing drive device (26) at the rising position of the lifting platform (2), and the contents of the container (200) are lowered to be discharged to the input port (300). When opening the release valve (95) for the container and making the outlet of the container correspond to the height of the inlet (300), if the container gets on the inlet (300), the hydraulic cylinder device for pressing (81) The working oil inside escapes to the tank (90) through the open release valve (95), the upper claw (42) opens, the clamp on the upper edge (201) of the container opens, and the container falls. There is a risk of In the first embodiment, such a danger can be eliminated without locking the upper claw (42) and opening it.

To lower the container (200) to the floor, the reversing frame (25) is returned to its original horizontal position by the manual reversing drive device (26) to erect the container (200), and the lowering release valve ( 95)

It is discharged to 0) and the lift table (2) descends. While descending, the check valve (97) operates by the cam plate (36) to open the branch flow path (93) leading to the pressing hydraulic cylinder device (81), but the lift table (2) and the container (200) are opened. Priority is given to the discharge of working oil from the lifting cylinder device (23) under the influence of weight.

A little before the elevator (2) reaches the descending end,
The hitting part (62) on the rod member (6) hits the receiving part (10) of the carriage (1) to prevent the rod member (6) from descending, and only the tilting post (3) including the reversing frame (25). Further down. As a result, by the action of the link mechanism (51), the hanging piece (52) rotates in the opposite direction to the above and returns to the original standby position. When the lift table (2) reaches the lower end, the container (200) is grounded to the floor surface, and the piston rod (85) of the hydraulic cylinder device for pressing (81) is retracted by the force of the spring (86) to store the working oil in the tank ( Discharge to 90). As a result, the upper claw (42) is opened and the clamp on the upper edge (201) of the container can be released.

As described above, the closing operation of the upper claw (42) clamps the upper edge (201) of the container by the upper claw (42) and the lower claw (41), the lifting operation of the container (200) and the hanging piece. The support operation of the container lower edge (202) due to the catch of the container (52) on the container lower edge (202) is automatically performed by the stepping operation of the hydraulic pump (92). Forgetting to hang (52) does not cause a major accident by flipping the drum in the raised position.

Further, since the upper claw (42) and the pressing hydraulic cylinder device (81) for driving the hanging piece (52) are connected to the check valve (97) which is convenient at the container lifting position, the pressing hydraulic cylinder is connected. It is possible to prevent accidental discharge of the working oil from the device (81) and eliminate the risk of the container falling.

The link mechanism (51) converts the movement in which the rod member (6) relatively projects from the lower end of the tilting post (3) into the movement in which the hanging piece (52) rotates from the lower side to the front side.

As in the case of the first embodiment, however, as shown in FIG. 1, the trolley is used for the container (200) standing on the floor.
(1) is thrust into the inversion frame (25) of the lift table (2) to invade the container body, and the lower claws (41) of the upper support means (4) are applied to the upper part of the body. The clamp screw (43) shown in FIG. 11 is rotated to close the upper claw (42), and the lower claw (41) and the upper claw (42) clamp the upper edge (201) of the container upper edge.

When the hydraulic pump (92) is stepped on, the lifting platform (2) is lifted by the lifting cylinder device (23) while the upper edge of the container (200) is clamped. As described above, the free ends of the arms (66) and (66) are lowered by the elevation of the lifting platform (2),
The rod member (6) is tilted by its own weight and the spring (87).
As shown in FIG. 15, the hooking piece (52) is rotated forward by the action of the link mechanism (51) relative to (3), and the claw piece (52a) at the tip is moved to the lower edge of the container ( 202). or,
The plate piece (63) on the rod member (6) hits the lower hitting shaft (72) to prevent the rod member (6) from further protruding.

The upper edge (201) and the lower edge (202) of the container (200) are supported by the upper support means (4) and the lower support means (5). As described above, the lifting member (2) is lifted to move the rod member.
(6) is a movement toward the upper support means (4) side with respect to the support shaft (103) by the lock member (101), that is, a movement in a direction in which the rod member (6) is pushed into the tilting post (3). The locking piece (52) does not come off from the lower edge (202) of the container (200) when the container (200) is lifted or inverted.

FIG. 16 shows a state in which a container having a height a little larger than that in FIG. 15 is supported, and the rod member (6) has a lower contact shaft.
Before hitting (72), the hanging piece (52) is hooked on the lower edge of the container (200a).

To lower the container (200) to the floor, return the container (200) in the raised position to the standing posture, and then release the lowering release valve.
Open (95). The working oil in the lifting cylinder device (23) flows out to the tank (90), and the truck (1) descends.

A little before the elevator (2) reaches the descending end,
The hitting portion (62) above the rod member (6) hits the receiving portion (10) of the carriage (1) to prevent the rod member (6) from being lowered, but the tilting post.
(3) descends. When the contact part (62) hits the receiving part (10) (10), the free ends of the arms (66) (66) are slightly lifted up relative to the rod member (6), and the unlocking rod (105) is slightly moved. Push up to unlock the lock member (101) with respect to the support shaft (103). This causes the rod member (6) to tilt post.
It is pushed relative to (3), and by the action of the link mechanism (51), the hanging piece (52) rotates in the direction opposite to the above and returns to the original standby position.

As described above, the lifting operation of the container (200) and the supporting operation of the container lower edge (202) by the catch piece (52) being caught by the container lower edge (202) are the foot operation of the hydraulic pump (92). Since it is automatically performed by,
Also, since the hanging piece (52) is forgotten to be hung, the drum can is not inverted at the raised position, which causes a serious accident.

Further, the locking means (10) by the locking member (101)
Due to 0), the hanging piece (52) does not come off from the lower edge (202) of the container during the lifting operation or the reversing operation of the container, so that the risk of the container falling can be eliminated.

In the second embodiment, the lock member (10
The spring (87) for urging 1) has a function of pushing the rod member (6) out of the tilting post (3), but the lock member (101) is supported by a torsion spring (not shown) or the like to support shaft (103). The rod member (6) is biased only in the direction in which it engages with the tilting post (6).
It can be implemented even if there is no action to push out from (3).
In this case, when the lift table (2) is lifted, the rod member (6) relatively protrudes from the tilting post (3) only by its own weight, and the bar
The (52) can be rotated in a direction in which the lower edge (202) of the container is hooked.

In carrying out the present invention, the upper support means (4) is
The present invention is not limited to the configuration of the above-described embodiment, as long as it can reliably support the upper portion of the container, and the present invention is not limited to the configuration of the above-described embodiment, and various modifications can be made within the scope of the claims. is there.
