16 is a projecting piece 17 that is in contact with the rear end of the swinging rod 7
The stopper body 16 has a locking piece 19 on its upper part that forms a recess 18 to enable locking. It is provided so that it can slide vertically on the side surface of a fixing plate 22 provided on the rear side of the transporter main body 1 in the inserted state and can swing around the bolt 21 . Reference numeral 23 denotes a spring which constantly applies a tensile force in the direction of arrow a to the lower part of the stopper body 16.

The present embodiment has the above-described configuration, and next, the lifting and transporting work of the drum can 27 using the transporter will be explained.

First, as shown in FIG. 1, the entire transporter is brought close to the drum 27, and then the operating lever 11 at the rear end of the hook rod 9 is swung to open the claw on the tip side as shown in FIG. The ten plate bodies 30 are brought into contact with the inner circumferential surface of the ear part 28 formed on the upper part of the drum can 27.
On the other hand, the abutment and engagement plate 14 moves up and down as well as swings slightly in the front-rear direction in conjunction with the hook rod 9 through the action of the link mechanism of the hook rod 9, the auxiliary rod 12, the auxiliary link 13, etc. However, when the upper edge of the drum 27 is aligned with the lower edge of the bulging portion 29 on the upper outer periphery of the drum can 27 or is located slightly below,
The concavely curved front surface of the corresponding connecting and engaging plate 14 is brought into contact with the outer surface of the drum can 27. At this time, the abutting plate 15 of the elevating frame 6 also comes into contact with the outer surface of the lower part of the drum can 27, similarly to the abutting and engaging plate 14.

Next, in the above state, if the foot lever 24 is depressed to rotate the swinging rod 7 in the direction of arrow b, the elevating frame 6 will rise as shown in FIG. 3. At this time, since the rear side of the hook rod 9 is raised as the lifting frame 6 is raised, the claw part 10 at the tip firmly presses the inner circumferential surface of the ear part 28 of the drum can 27 from the inside. , As a result, the upper part of the drum 27 has the claw part 10
and the abutment and engagement plate 14, and the abutment and engagement plate 14 is securely engaged with the lower edge of the bulge 29, and is lifted together with the elevating frame 6. It is. In addition, the elevating frame 6
is raised while maintaining a normal vertical posture by the action of the auxiliary link 8, etc., and is not tilted in any way.
5, the stability is excellent even in the rising state.

Furthermore, if the rear end side of the swinging rod 7 is lowered as described above, the projecting piece 17 on the rear side of the swinging rod 7 will move from the state shown in FIG. Enter the inside and tighten the stopper body 16 with the bolt 21.
In order to push the stopper body 16 down, the stopper body 16 is rotated in the direction of arrow c by the elastic force of the spring 23. Therefore, if the worker removes his/her foot from the foot lever 24 in this state, the protruding piece 17 of the swinging rod 7 will rise due to the load of the raised drum 27 and the lifting frame 6, so that the same As shown in Figure C, the projecting piece 17 is securely engaged and locked inside the locking piece 19. In addition, when the stopper body 16 is locked, the bolt 2 is moved by the lifting force of the protruding piece 17.
1 and returns to the original raised position, thereby completely locking the swinging rod 7, and in this state appropriate transportation work can be performed.

Furthermore, to explain the case of lowering the drum 27, first step down the foot lever 24 again to lower the protrusion 17 in the direction of arrow d from the state shown in FIG. Since the locking piece 19 is rotated in the direction of arrow e by the elastic force of the spring 23 and the locking piece 19 is separated from above the protruding piece 17, if the foot lever 24 is left in the free state, the rocking The rod 7 naturally swings back to its original state due to the weight of the drum can 27, etc., and the drum can 27 is thereby lowered. Therefore, after lowering the drum can 27, if the operating lever 11 is operated to move the claw part 10 of the hook rod 9 away from the ear part 28 of the drum can 27 and the entire transporter is moved backward, the drum can 27 can be lowered. It can be easily separated from the transporter and released.

Further, when the transporter is not in use, the upper rod 6a of the lifting frame 6 is placed in contact with the upper end of the fixed frame 4, and the auxiliary rod 12 is placed on the upper end of the lifting frame 6.
It is in a compact standby state where it is placed in contact with the horizontal rod 6c.

In addition, in the above embodiment, the stopper body 16
A long hole 20, a spring 23, etc. are provided in the stopper body 16 so that the locking piece 19 of the stopper body 16 and the rear side of the swinging rod 7 can be automatically engaged and disengaged by the user's depression of the foot lever 24. However, the present invention is by no means limited to this, and the point is that the swinging rod 7 may be provided so that it can be freely engaged with and disengaged from the rear end when the rear side of the swinging rod 7 is lowered to raise the elevating frame 6. .

Further, in the above embodiment, when forming the claw portion 10 of the hook rod 9, the curved plate body 30 is used to greatly reduce the area where the plate body 30 contacts the ear portion 28 of the drum can 27. Since the claw portion 1 according to the present invention is large, it has the advantage of being excellent in stability and reliability when lifting the drum 27.
The specific configuration of 0 is not limited to this, for example, the above-mentioned plate 30 etc. are not provided, but a mere claw piece 10 is used.
It is also possible to form the claw piece 10a only by a, so that the claw piece 10a abuts and engages with the inner circumferential surface of the ear part 28 of the drum can 27.

In addition, the present invention is not limited to the specific shapes and mounting structures of each part as in the above embodiments, and the design of the specific configuration of each part can be changed within the scope of the present invention. Furthermore, the container to be transported in the present invention is not limited to metal drums, and the specific type of the container is not critical as long as the container has an ear and a bulge on the top.

(Effects of the invention) As described above, the present invention has a hook rod that has a claw that abuts and locks on the inner peripheral surface of the ear of a container such as a drum, and a bulge on the outer periphery of the upper part of the container. The abutting and engaging plate to be locked is connected by link, and the hook rod and the abutting and engaging plate are connected to an elevating frame that can be raised and lowered by swinging the swinging rod. In order to lift the container, the hook rod is brought into contact with the container's ear, and the top of the container is held and gripped by both the hook rod and the abutment engagement plate, and then the swing rod is operated. This can be done in an extremely simple one-touch operation by simply lifting the lifting frame.
The workability has been extremely good and the work can be done quickly, which has resulted in a special effect.

Moreover, since the present invention lifts the container while it is locked with the hook rod or the abutment engagement plate,
It is difficult to cause slippage with the container, and the container can be gripped reliably, and the abutment plate is brought into contact with the lower circumferential surface of the container to suitably prevent the container from swinging.
It also has the remarkable effect of making container gripping and lifting operations even more reliable.

In addition, since the present invention engages and grips a portion of the top of the container with a hook rod or the like provided on the top of the lifting frame that is raised and lowered by a swinging rod, the outer circumferential side surface of the conventional drum can is The overall structure is more compact than a means in which the arms are sandwiched from both sides. In particular, the present invention has an elevating frame that is formed in a substantially rectangular shape on the sides, and has a fixed frame and an elevating frame below the upper rod of the elevating frame. Since an ink mechanism is provided for lifting and lowering the frame, and a link mechanism between the lifting frame and the hook rod is provided above the lower rod, the overall structure becomes more compact and easy to use. has advantages.

In addition, since the present invention employs an ink mechanism to connect each part, it has the advantage of being extremely simple to manufacture and highly reliable in operation.
