Description

DETAILED DESCRIPTION OF THE INVENTION This invention provides a mechanism for fixing the wire lobes to a drum protection plate that covers the cylindrical surface of the drum around which the cargo handling wire lobes are wound.
The present invention relates to an improvement of a hoist in which a support member supporting a shaft for suspending an illumination is welded and a reinforcing member is provided to reinforce the support member mounting portion of the drum support plate.

This conventional ash wood will be explained according to the fJ1 diagram and the %2 diagram. In the figure, (lA) and (IB) are well-known sliding side plates that are paired with each other, and (2A) and (2B) are horizontally spaced apart from each other, and both ends thereof are connected to the corresponding pulleys. This is a hanging rod suspended from the lower part of the side plates (IA) and (1B), and is used to suspend an outer frame for a hoist, which will be described later. (3) is a well-known drum that is placed within the outer frame of a hoist and around which a wire robe for cargo handling (described later) is wound; (4) is suspended from hanging rods (2A), C2B), The outer frame of the hoist surrounds and supports the drum (3), and is arranged correspondingly at both axial ends of the drum (3).

(4kl), (4Jn) are welded vertically to the lower surface of the horizontal bent part (41)a at the bottom of the dome retainer plate (4D), and are spaced apart from each other.

(5) L- is a shaft whose one end and the other end are supported by supporting plates (4K), C4L), (6) is a shaft whose upper part is loosely fitted to the shaft (5), and whose lower end is a shaft of the wire puller L for cargo handling, which will be described later. A cylindrical support member (8) is a wire rope for cargo handling, which supports the cargo via a terminal fitting (7) fixed to the terminal, one end of which is engaged with the drum (3) and the other end is a support member. Element(
6) The hook block (9) is suspended by the K and is wound up and unwound onto the drum (3). Note that FIG. 2 is a side view of FIG. 1 as viewed in the direction of arrow 1.

With this structure, the seven vine blocks (9) move up and down as the drum (3) rotates forward and backward, making it possible to carry out cargo handling operations.
) and (4N) are placed and welded on the inside of the drum protection plate (4), so the position of the shaft (5) must be separated from the drum (3), and the hoisting height of the hook block (9) is Not only is the welding cost low, but the welding work is difficult to perform, resulting in poor productivity.

The present invention has been made in view of the above-mentioned conventional circumstances, and includes a support member for supporting a shaft for suspending a fixed side pant of a wire rope for cargo handling, which is in hot contact with a drum protection plate. This invention has been made for the purpose of increasing the hoisting height of a hoist provided with a reinforcing member for reinforcing the support member mounting portion of the invention. Let's discuss an example. In the figure (4Db)1-t
Bent part formed by bending the lower half of the drum protection plate (4D) into the drum (3) gIJ, (4P) Vi mid drum 3)
It is a support member made of channel steel that opens downward in parallel with and supports a pair of support plates to be described later.The upper outer drum (3) 1ill @ is welded to the outer side of the curved part (41) b). That's what happens. (4Q) has a bent part (4Q) at the upper end.
J) A reinforcing member whose lower end is welded to the upper outer side of a) on the opposite side to the upper outer drum (3) of the support member (4P), which connects the drum protection plate (4D) and the support member (4P). It is intended to reinforce the (4R), (4B) #i A support member consisting of a pair of support plates arranged and welded at a predetermined distance from each other in the axial direction of the drum (3) at the lower opening of the support member (4P), It corresponds to support both jaws of the shaft (5). In addition, other code theory F! A is Figure 1,
The explanation is the same as that of FIG. 2, so the explanation will be omitted. Also, the fourth
The figure is a side view of FIG. 3 viewed from the direction of the arrow ■.

With this structure, cargo handling can be carried out by rotating the drum (3) as in the past, but the reinforcing member (4Q) is placed outside the drum protection plate (4D) to protect the drum. Place the bottom of the board (4D) on the drum (3
) Since it is bent at @, the shaft (5) can be placed higher than before.

It should be noted that the support plates (4R) and C4B) may be integral with each other, and that the support plates may be directly welded to the drum retainer plate (4D) without the support plate (4Q); It goes without saying that the bent portion (4Dt) may be welded separately from the drum retainer plate (4D), and the reinforcing member (4Q) may be integrated with the drum retainer plate (4D). stomach.

This departure F! As described above, a bent part that approaches the drum is formed at the bottom of the drum retainer plate, and a support that supports the shaft that supports the fixed @ end of the cargo handling wire rope is formed on the outside of the lower part of the bent part. The side part of the drum on the outside of the upper part of the member was welded, and the side part of the support member on the outside of the upper part opposite to the drum was welded and connected to the upper part of the bent part through the reinforcing member, so that the wire rope could be fixed. The end position can be positioned higher than before, and therefore, not only can the winding height be increased, but also the above-mentioned fixing 1Iilf@ does not protrude outward and can be miniaturized, which is extremely superior. This has the effect of providing a high-quality hoist.
