Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a watertight device for a hatch cover, and more particularly to a watertight device for a hatch cover between adjacent panels.

Generally, on a cargo ship such as a container ship, a cargo handling schedule is determined in advance for cargo on the hatch cover or cargo in the hold. Cargo handling was said to be almost non-existent.

However, after oil shocks, the amount of cargo handled per port has decreased, and the number of cases in which cargo handling is carried out over several ports in one voyage has increased. Increasingly, out-of-order cargo handling is required.

In such a case, in a conventional pontoon-type hatch cover 1 etc. consisting of a plurality of panels A and B as shown in Fig. 1, the watertight mechanism between the panels A and B is Fix the packing 2 to one of the and tightening bar 3 to the other.
Since it is constructed by fixing the panels, the order in which the panels are opened and closed naturally occurs. Therefore, even if you only want to open one panel (for example, B), you may have to open the other panel (for example, A) first, which is a wasteful task. Especially when there is a container or other deck cargo placed on the panel. In such cases, the labor and time required for the work are doubled, making cargo handling uneconomical.

As a countermeasure against this problem, recently, as shown in Figs.
Link-type (FIG. 2) and hinge-type (FIG. 3) watertight devices have been proposed in which the order in which panels are opened and closed is not restricted, and the panels are rotatably supported around the edges.

However, the former has a complicated mechanism, requires time to assemble and adjust, and is an expensive device.
In the latter case, the mechanism is simple, but since the hinge is large and rotates within the panel, the depth of the panel (i.e., hatch cover) is required to be large, and it has the disadvantage that it cannot be attached to a short hatch cover. It was hot.

The present invention has been proposed in view of the above, and an object of the present invention is to provide a watertight device for a hatch cover that can be freely opened and closed on either side of the panel, is inexpensive, and can be applied to short panels.

In order to achieve the above object, the present invention has a plurality of packings attached to one of the opposing edges of two adjacent panels, and a plurality of tightening bars attached to the other edge to be crimped to the packing. Assuming that the hatch cover consists of two panels, either the mounting part of the seal or the tightening bar is rotatably supported via a slide pin on a hinge mount provided at the edge of the panel, and is provided with a slide slit that freely guides the slide pin in the advancing and retracting direction with respect to the opposing panel edge, and when the panel is opened/closed, the mounting portion is retracted to the panel edge in an inclined state via a drive mechanism. I tried to make it wet.

That is, in the above configuration, when the mounting portion of the packing or tightening bar is released, the sliding slit of the hinge mount allows the mounting portion to be moved in a direction to retreat with respect to the edge opposite to the support side edge. Therefore, there is no need to completely erect the mounting part, and it remains in an slanted position.
It can be stored in a position that does not interfere with the opposing panel edges.

Embodiments of the present invention will be described below based on the drawings.

As shown in FIG. 4, a hatch cover 12 consisting of panels 11A and 11B is placed on the hatch edge material 10. The opposing edges of the panels 11A and 11B are held watertight by a watertight device 13.

The watertight device 13 includes a swing frame 14 arranged along the joint surface of the panels 11A and 11B,
A predetermined number of cams 15 for tightening the swing frame 14, and hydraulic jacks 16, 1 arranged as part of the drive mechanism on the sides of the panels 11A, 11B to operate the swing frame 14 and the cams 15.
7.

As shown in FIGS. 5 and 6, two gaskets 18a and 18b are fixed to the swing frame 14 along the longitudinal direction of the frame, and the panel 11
The above gaskets 18a and 18b on the edges of A and 11B
Tightening bar 1 arranged in a position facing the
9a and 19b in a watertight manner.

Furthermore, a bracket 2 is attached to the swing frame 14.
0 are attached at certain intervals in the longitudinal direction of the frame, and can freely rotate and slide within the slide slit 23 of the hinge mount 22 provided at the edge of the panel 11B via the slide pin 21. It's summery.

This movement of the swing frame 14 is caused by engagement between pins 25 attached to both ends of the swing frame 14 via brackets 24 and guide slits 26 provided on both sides of the panel 11B, as shown in FIG. Slide pin 21 up to a certain angle at first
It rotates around , and after rotating to a normal position, it is regulated so that it is horizontally moved toward the interior of the panel 11B while maintaining the same angle.

This operation is performed by telescopically operating hydraulic jacks 16, which are disposed on both sides of the panel 11B and connected to the pin 25 via a link 27.

The hydraulic jack 16 has hook-shaped ends, and when the swing frame 14 is opened, the swing frame 14 and the panel 11B are fixed by a lock pin 28 provided in the guide slit 26 (or the frame 14 is fixed to the cam 15).
It is a portable type that can be removed after it has been tightened.

Therefore, the hydraulic jack 16 (including the hydraulic jack 17 described later) can be removed after use and used for other purposes, and should be stored in a separate location to protect it from damage during cargo handling, rust during voyage, etc. be able to.

Swing frame (cleat) tightening cam 1
5 are fixedly provided at positions facing the bracket 20 on the drive shaft 30 passing through the panel 11A, and a roller is provided on the contact surface of the cam 15 with the bracket 20 to reduce resistance during tightening. 31 is attached.

As the drive shaft 30 rotates, the cam 15 is rotated clockwise in FIG. The rotation is regulated by a stopper 32 provided at the edge of the panel 11A so that it cannot rotate beyond the overstroke of the panel 11A.

The meaning of tightening the cam 15 beyond the dead point in this way is that once the cleat is tightened against the repulsive force from the swing frame 14 side due to the gaskets 18a and 18b, the cam 15 will always have a stable force relationship in the direction that prevents it from escaping. This is for the purpose of maintaining the condition.

The rotation of the drive shaft 30 is controlled by a lever 33 attached to both ends of the drive shaft via a nut or the like, as shown in FIG.
This is done by operating hydraulic jacks 17 provided on both sides of the panel 11A.

This hydraulic jack 17 is also formed into a hook shape at both ends like the aforementioned hydraulic jack 16, and can be removed after the lever 33 is fixed to the panel 11A at a predetermined position (the tightening position of the cam 15) by the lock pin 34. It's getting old.

In addition, as shown in FIG. 8, the swing frame 14
Guide pieces 35 and 36 are provided at predetermined positions on the panel 11B, respectively, so that when the frame 14 is closed, the frame 14 is reliably set in a fixed position along its entire length, and lateral movement is restricted after the frame 14 is set. It's summery.

Also, gaps A and B are formed between the guide piece 35 and the panel 11B and between the frame bracket 20 and the touch plate 37 of the panel 11A, respectively.
When a load is placed on panels 11A and 11B, the packing 18
a, 18b are prevented from being overcompressed beyond the specified limit.

Because of this structure, when you want to release the watertight state of panels 11A and 11B shown by solid lines in Figure 6 and open either panel 11A or 11B, first open the hydraulic jack that was removed. 1
6 and 17 in the predetermined positions (see FIG. 7).

First, after removing the lock pin 34 of the hydraulic jack 17, the lever 3 is operated by extending it.
Rotate 3 counterclockwise. As a result, the cam 1 rotates integrally with the lever 33 via the drive shaft 30.
5 similarly rotates counterclockwise to release the swing frame 14.

Next, when the hydraulic jack 16 is operated to the contraction side, the swing frame 14 is initially The panel 11 rotates around the slide pin 21.
The watertight state of panels A and 11B is released, and the panels are horizontally moved (slided) from the predetermined inclined position and stored at the edge of panel 11B.

In this state, the panels 11A and 11B can be opened using a predetermined means (not shown), but as described above, the swing frame 14 is fixed to the panel 11B with the lock pin 28, and the panels 11A and 11B are opened after the hydraulic jack 16 is removed. You can also do that.

On the other hand, when the panels 11A and 11B are closed and maintained in a watertight state, it is easily understood that the operation in the opposite manner to the above-mentioned operation can be performed, so a description thereof will be omitted.

As described above, according to this embodiment, the swing frame 14 rotates and tilts at the edge of the panel 11B to release the watertight state between the panels 11A and 11B, and also slides horizontally in the tilted position to move the panel 11B. Since the swing frame 14 does not protrude outward from the edge of the panel 11B, the opening/closing order of the panels 11A and 11B is not restricted, and since the rising height of the frame 14 is low, the depth of the panel 11B is The hatch cover 12 does not require much height and can be applied to a hatch cover 12 having a short height.

In addition, the slide pin 21 itself that rotatably supports the swing frame 14 is attached to the hinge mount 22.
Since the swing frame 14 is supported so as to be horizontally movable by the slide slit 23, the swing frame 14 can be rotated and slid in series and simultaneously.
The swing frame 14 can be driven by a single hydraulic jack 16, resulting in a simple structure and no increase in cost.

As explained above, according to the present invention, either one of the mounting parts such as a swing frame where a packing or tightening bar is provided is rotatably supported via a slide pin on a hinge mount provided at the panel edge. On the other hand, the hinge mount is provided with a slide slit that freely guides the slide pin in the advancing and retracting direction with respect to the opposing panel edge, and when the mounting portion is opened, the slide slit of the hinge mount allows the By moving the mounting part in a direction away from the supporting edge and the opposite edge, it is possible to store the mounting part in a diagonal position without interfering with the opposing panel edge. I did it like this,
It is possible to provide an inexpensive and versatile hatch cover watertight device that can be applied to shallow and small panels and does not restrict the order in which the panels can be opened and closed.
