ある。Further, in the drum can lifting device, the clamp device is lowered while contacting the ear of the drum can, and when it is raised next, the ear of the drum can is automatically clamped by the lower claw and the upper claw to lift the drum can. However, there is a device in which when the lifting device is lowered from this hoisted state, the clamp is automatically opened due to the landing of the drum can and only the lifting device is raised as it is. In this case, the structure of the hanger becomes more complicated, and it takes time to assemble. The present invention is
A clamp device that solves the above problems is disclosed.

When the weight of the nail is not acting, the claw support (3) and the lower claw (5) are lifted by the springs (37) (50),
The lower part of (3) is in the forward position, and the space between the upper claw (4) and the lower claw (5) is open. When the lifting device is lifted, the claw support (3) ascends by sliding the guide surface (34) to the drum can ear (71). When the lower claw (5) is caught by the drum ear (71) and the weight of the drum can (7) acts on the lower claw (5), the claw support (3) causes the spring (3) to move.
The lower claw (5) lowers relative to the lifting frame (1) against 7) and the spring (50) relative to the claw support (3), and the upper claw (5) lowers. (4) is pulled down, and the ears (71) of the drum can (7) can be clamped by the both claw pieces (41) and (51) of the both claws (4) and (5). When the clamped drum can is lifted from the lifted state and landed, the drum can (7) pushes up the upper claw (4) and lifts the lower claw (5) to move backward to release the clamp. When the lifting tool is lifted, the lifting tool rises as it is, and when the claw support (3) crosses the drum (7), the claw support (3) rotates forward around the pin (39) to the initial state.

体(３)の後退位置が決められている。When the lower claw (5) moves down, it moves forward with respect to the claw support (3), but acts on the claw support (3) in a drum can.
Due to the load of (7), the supporting member (14) is also lowered against the spring (22) and slightly retracted until it hits the mast (12), so there is almost no change in the front-rear position of the clamp with respect to the drum can (7). In the example, when the drum can is lifted,
The retracted position of the claw support (3) is determined so that the body of (7) hits the arcuate contact member (15) on the lifting frame (1) and the drum can is slightly tilted forward.

Insert the two clamping devices (2) so as to face the drums respectively. Hereinafter, the movements of the four clamp devices (2) are the same. As shown in FIGS. 9 and 15, when the clamp device (2) descends, the ear portion (71) of the drum can (7) hits the lower guide slope (34a) of the claw support (3), and FIGS. As shown in FIG. 5, as the clamp device (2) descends, a rearward pressing force acts on the claw support (3). This allows the nail support
(3) rotates backward around the pin (39), and the claw support (3) is hidden between the wall plates (17) and (17), but the front end of the lower claw piece (51) has a claw. It still projects forward from between the support body (3) and the wall plates (17) (17). When the lower claw piece (51) reaches the ear portion (71) of the drum can (7), the nail support (3) keeps the ear portion (71) until the lower nail piece (51) crosses the ear portion (71) downward. ) To retreat, lower nail piece
When (51) crosses the ear (71), the lower claw piece (51) slightly moves forward at the lower part of the ear (71) until it hits the body of the drum.

きる。As shown in FIGS. 11 and 17, when the lifting device is lifted and the clamp device (2) is raised, the drum can ear portion (71) is caught by the lower claw piece (51) and a downward load is applied. As a result, the lower claw (5) is moved relatively forward by the cam surface (53) and moves downward relative to the claw support (3). The upper claw (4) is pulled down as the lower claw (5) descends,
The space between the upper claw piece (41) and the lower claw piece (51) is closed, and the drum can ear (7
1) is clamped. When the lifting frame (1) is further pulled up, a downward load acts on the claw support (3), and the spring (37)
Against this, the claw support (3) descends by the inclined long hole (38) in the upper part, the notch (31a) faces the hooking part (19), and the claw support (3) in the lowered position is pin ( 39) Rotate backward around the center,

The pin (39) is urged to rotate forward by the pin (39) from between the wall plates (17) and (17), but the rotation of the claw support (3) is blocked by the drum can (7). . Further, as shown in FIG. 19, when the claw support (3) is relatively lowered with respect to the wall plate (17), the spring for urging the lower claw (5) is urged as compared with the initial state of FIG. (50) is stretched and biases the claw support (3) upward (the upward biasing force of the spring (50) is weaker than the rotational biasing force of the spring (37)). Nail support
Since the engaging portion (19) on the wall plate (17) is fitted in the notch (31a) of (3), the pawl support body (3) is relatively elevated with respect to the wall plate (17). Absent.
