Description

[Detailed description of the invention]

The present invention relates to a hanging hardware, and more particularly, to a hanging hardware suitable for moving up a bottom plate that is separately produced in the work of assembling a bottom plate for a grating of a marine diesel engine. In general, in a marine diesel engine, a grating floor plate is installed at an appropriate height and used as a scaffold, etc. - Such a floor plate has a recess or the like so that one edge of the grating comes into contact with the diesel engine. It has a complicated planar shape, has an L-shaped raised part on its periphery, is manufactured in one piece, and is assembled into a diesel engine. Conventionally, in the work of assembling grating floor plates, wire lobes have been used to move the divided floor plates from a high place to an assembly position. this is,
As shown in FIG. 1, the wire robe 3 was wrapped around the recess 2 of the bottom plate 1 and lifted directly, and the work was done while keeping the bottom plate balanced. However, in the conventional method described above, there is a problem in that the wire rope 3 slips and loses balance, resulting in an extremely high risk of a falling accident. Moreover, this work area is located in a high place, the footing is poor, and the shape of the floorboards is not uniform, making it difficult to maintain a center of gravity, which exacerbates the above-mentioned problems. However, it is still extremely difficult to hang and turn the wire rope "3" on the bottom plate 1, and it takes a lot of time depending on how the bottom plate 1 is placed, and it is difficult to remove the wire rope 3. The present invention has focused on the above-mentioned conventional problems, and has been developed not only for grating bottom plates but also for all IB hardware for members having an L-shaped rising edge at the edge, making sling work easier. An object of the present invention is to provide an entire lifting hardware that can be held safely and firmly in a gripping state.
It has an approximately U-shaped hanging tool body with a lifting lever pivotally attached to the outer surface of the handle, and a handle that can slide freely in a groove provided in the handle of the hanging tool main body, and has an L-shape along with the hanging tool main body. and a hook body capable of forming a letter-shaped gripping space, and the hanging tool body and the hook body each have an arm pivotally connected to the handle, and the arm member is connected with a pin, and The connecting portion is rotatable beyond the extension line of the pivot point between each arm, the hanger main body, and the hook body, and is housed in a groove in the handle of the hanger main body to enable a υ locked state. It is composed of With this configuration, by extending both arms in a straight line, the hook body is separated from the hanging tool body, expanding the gripping space, and it is possible to easily engage the edge of the target grating floor plate on 1β. can. From here. Pull out the pin joint parts of the arms to the outside, rotate the pin joint parts around the arm pivot part on the suspender main body side, and make the pin joint ifB 1.

[By housing the three tools in the groove of the main body, the holding space of the first tool becomes an L-shaped space that matches the shape of the bottom plate and is locked. Therefore, by pulling up the upper metal fitting 113 via the lifting lever, the bottom plate can be reliably gripped and lifted up. in this way,
The sling work is done only by operating the arm part.
Moreover, it can be easily carried out regardless of the mounting form of the bottom plate. Furthermore, since the lifting hardware is securely gripped, there is an advantage that the work can be carried out safely without having to consider the balance of the bottom plate. A specific embodiment of the upper metal fitting according to the present invention will be described in detail below with reference to the drawings. Fig. 2 is a side view of the entire upper metal fitting according to this embodiment. The upper hardware mainly consists of a U-shaped hanging body 10, an L-shaped hook body 30, and two types of arms 5o and 7o that connect these two. 11'3 Specifications of the hanging body 10 The structure of this hanging device is shown in Figs. 12 are integrally formed with a grip block 13 at the tip of the short part and a connecting plate 15 connected to the inner edge of the long handle 14.

This is achieved by locking the r6 tool body 10 to the r6 tool body 10. For this reason, a locking piece 23 is provided on the hanging tool main body IO so that the rotation of the arms 50-700 is stopped in the locked state. It should be noted that a stopper claw portion 75 is formed at one end of the arm 7() on the side where it is connected to the arm 5o. This stopper claw portion 75 is a safety device that prevents the lifting fitting from being unlocked when it is locked as described above. This has a curved surface that can be engaged with the distal end roller 24 of the upper lever 2o 113. Then, with the arm 50.70 in the locked state (the position shown by the broken line in FIG. 2), the Ii4 upper lever 2o is rotated counterclockwise in the 11 direction in the figure to engage the connecting roller 24 and the claw portion 75, and the lifting lever 2o By raising 10 in the engaged state, the 81° removal movement (clockwise rotation in the figure) of the arm 5 (170) is prevented.'The arm 7o still has its outer edge 11 A handle 76 is provided at the handle 76. This is used to lock and release the l11-hi metal stem. The metal fittings are in the locked state in advance.

0 slides completely within 7H1er of the hanger main body 10, and the opening of the gripping space 33 of both is expanded. By further rotating the arm 70 around the bottle coupling portion 740, the hook body 30 is fully opened at the position indicated by the dashed line. In such a state, for example, the U-shaped groove 11 of the hanging tool body lO is inserted into the upright part of the grating bottom plate 1.
Next, the hook body 30 and the arms 50 and 70 are all arranged in the opposite manner. That is, the hook body 30 is pushed into the bottom surface of the bottom plate, and the bottle connecting portion 74 of the arm 50-70 is turned counterclockwise so as to cross the pivot joint extension line Ai, and the arm 70 is locked to the locking piece 23. Let it happen. In this state, the thinking point of arm 50.70 is connected tN
