Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a metal for lifting a lid plate.

[Prior Art] For example, in a container ship, when loading and unloading a container in a hold, the hatch cover 101 shown in the perspective view of FIG. 5 must be lifted and moved to another place. Therefore, it is necessary to provide a hoisting hardware for hoisting the hatch cover. As this kind of hoisting hardware, for example, as shown in the partial enlarged view of FIG. The recess 103 is provided as a recess, and the twist lock pin 102 of the crane spreader for lifting the hatch cover is engaged with the lifting recess 103 and lifted.

As the structure of this lifting hardware, as shown in the plan view of FIG. 7 and the vertical sectional view of FIG. 8, a lifting recess 103 is installed on the upper surface of the hatch cover 101, and the twist lock pin 102 is inserted on the upper surface thereof. The long hole 103a is opened.

However, with such a structure, only the work of lifting the hatch cover 101 can be used, and the work such as fastening the hatch cover to the hatch has to be performed separately, and if the spreader opens and closes the hatch cover. It would be very convenient if the hatch cover could be automatically locked and unlocked by using the motions.

[Problems to be solved by the invention]

The present invention has been proposed in view of such circumstances,
It is an object of the present invention to provide a lid plate lifting metal item that allows the vertical movement of the lifting metal item associated with the lifting of the lid plate to be used as the operating force of the attached member.

[Means for solving problems]

To this end, the present invention has a plurality of through holes formed in the horizontal cover plate at appropriate intervals and an end plate in which a twist lock pin insertion hole is formed so that the upper end is blocked and the through hole cannot rotate. Direction, the movable lifting recess cylinder is loosely inserted, the stoppers for restricting the upper limit position and the lower limit position of the axial displacement of the movable lifting recess cylinder with respect to the insertion hole, and the horizontal lid plate attached thereto. Displacement conversion means for converting the axial displacement of the movable lifting recess cylinder into a horizontal displacement.

[Action]

With such a configuration, the twist lock pin of the spreader is inserted into and engaged with the movable lifting recess metal object of the cover plate in the closed state, and then the spreader is lifted to operate in conjunction with the movement of the movable lifting recess metal object to the upper position. Strokes in one direction, lowers the spreader to close the cover plate, and separates the spreader from the cover.The movable lifting recess moves the above operation in the other direction in conjunction with the movement to the lower position of the hardware. It can be used for various purposes such as locking and unlocking.

〔Example〕

An embodiment in which the present invention is applied to a hatch cover will be described with reference to the drawings. FIG. 1 is an overall perspective view showing a loading and unloading procedure by a spreader of the hatch cover, FIG. 2 is a partially enlarged view of FIG. 1, and FIG. 2 is a plan view showing the movable lifting recess metal part of FIG. 2, and FIG. 4 is a vertical sectional view taken along the line IV-IV of FIG.

First, in FIGS. 1 and 2, 2 is a hatch cover 1
With the twist lock pin of the crane spreader that lifts up, the twist lock pin 2 is inserted into the movable lifting recess metal fittings 3 provided at the four central parts on the upper surface of the hatch cover 1, and then the twist lock pin is rotated by about 90 °. The lifting recess metal fitting 3 is engaged.

Next, referring to FIGS. 3 and 4, an elongated hole 3a for inserting the twist lock pin 2 is formed on the upper surface of the lifting recess metal piece 3, and 5 is a bottom surface 3b of the movable lifting recess metal piece 3. With the provided central axis, the central axis of the holder 4 and the central shaft 5 of the central axis of the holder 4 are slidably inserted into the short cylindrical holders 4 which are fitted in the central portion of the upper surface of the hatch cover 1, respectively. The cross section has an oval shape or a square shape so that the central shaft 5 does not rotate in the holder 4.

And when the movable lifting recess hardware 3 descends,
The movable lifting recess metal piece 3 moves up and down between the lower position and the upper position so that its bottom surface 3b contacts the upper surface 4a of the holder 4, and when it rises, the flange portion 5a of the central shaft 5 contacts the lower surface 4b of the holder 4. It is freely inserted into the holder 4.

In opening the hatch cover 1 in such a structure, the twist lock pin 2 of the crane spreader is used.
Is inserted into the long hole 3a of the movable lifting recess metal fitting 3 provided on the upper surface of the hatch cover 1, and the
When it is rotated and engaged with the movable lifting recess metal fitting 3 and the hatch cover 1 is lifted, the central axis 5 of the movable lifting recess metal fitting 3 is guided by the holder 4 and ascended, and the flange portion 5a at the lower end of the central shaft. Is the bottom surface 4b of the holder 4.
The hatch cover 1 is hung up when it comes into contact with.

Therefore, as shown in FIG. 4, by equipping the bottom surface of the flange portion 5a of the central shaft 5 with a link mechanism including an eye plate, a lever, an interlocking rod and the like, other devices such as a hatch cover locking device and a hatch cover sealing device are provided. It can be used as an operating force.

Next, when closing the hatch cover 1, when the hatch cover 1 descends to a predetermined closed position and sits down, the load applied to the twist lock pin 2 of the crane spreader supporting the weight of the hatch cover 1 will be reduced. No load,
The movable lifting recess metal piece 3 descends to the lower position by its own weight, and the bottom surface 3b thereof comes into contact with the upper surface 4a of the holder 4, and the twist lock pin 2 rotates approximately 90 ° in the clockwise direction, so The engagement is released and the closing of the hatch cover 1 is completed.

[Effect of device]

In short, according to the present invention, the horizontal lid plate has a plurality of through holes formed at appropriate intervals, and the end plate having the twist lock pin insertion holes formed therein has its upper end closed so that the through hole cannot rotate. A movable lifting recess cylinder that is loosely inserted so as to be slightly movable in the axial direction, stoppers that respectively restrict the upper limit position and the lower limit position of the axial displacement of the movable lifting recess cylinder with respect to the insertion hole, and the horizontal lid plate. By providing the displacement converting means for converting the axial displacement of the movable lifting recess cylinder into the horizontal displacement, the vertical movement of the lifting hardware associated with the lifting of the lid plate can be used as the operating force of the attached member. The present invention is extremely useful industrially because it can obtain a metal for lifting a lid plate.
