Description

Supporting mechanism for the deck that can be raised inside the ship{SUPPORT MECHANISM FOR LIFTABLE DECKS INSIDE SHIPS}

The present invention relates to a liftable or liftable support mechanism for a deck or panel on a ship, which is carried by a vehicle, and is collectively supported in a vertical direction on a post or other carrier positioned laterally at a fixed height on the ship. A movable stop lug having a fixed stop member, distributed along the perimeter of each panel and arranged with an attached group of stop members, may be actuated to engage a desired stop member, the stop lug comprising: It is movably mounted to be placed in the disengaged position and in the locked position by remote operation by a lockable traction member lockable by a locking mechanism, and in the disengaged position, each said stop lug is inside of the peripheral edge of the attached panel. Actuated to be sent to the dispatched position in, in the locked position, each said stop lug is sent out of the peripheral edge of the attached panel to mount the panel on the desired stop member, said stop lug , After the operation of the traction member, is sent to the inside of the panel toward the center of the target panel.

There are several problems with existing support mechanisms.

The above problem is simply explained by the fact that many ship owners and shipbuilders want to have more flexible ships with several selectable heights of the car deck panels, so there tends to be many semi-automatic stoppers on the ship's posts. Can be. In this regard, the following problems arise:

* It is difficult to physically provide space for the parts of the support mechanism in the post and there will be many ropes/strings for towing.

* Cost increases because the weight of the component becomes heavier.

* Time-consuming work in shipyards involving a lot of welding increases.

* There is a risk of the column distortion due to heat induction during welding.

* A heavier structure is required.

* The source of error increases due to many ropes and many stoppers to be machined.

* The building height of the ship is increased.

In particular, after each movement of the stop lug to and from the cargo deck, it is movable not only to be able to raise the cargo deck to the desired height, but also to support the target cargo deck at the desired height on board. Unnecessary height requirements of the ship, as the mechanism of the load-carrying liftable panel and the movement of the load-carrying liftable panel to keep the stop lugs in place will be able to be placed in the intended positions. There is a problem with avoiding it.

For example, in Japanese Patent Application No. 62-173394, the above mechanism is disclosed, but it requires considerable upward movement and space to obtain a movable stop lug that can move freely without interference. Additionally, in this connection the conventional locking mechanism 10 is in the form of a low-height handle wheel. In this regard, a handle wheel is required for each rope, which results in a large number of handle wheels if there are many liftable panels.

The above known mechanism relates to a support mechanism 31 with a rotatably mounted stop lug 30, similar to a bird's head, and the rotatable tip of the stop lug, similar to a _{bird's beak 30 2} The (turnable tip) is disposed in contact with the fixed stop member 33 along the path in the vertical direction of the movement of the panel. See FIGS. 1 to 9.

By means of a handle wheel 10 located below the deck De, the ropes 8, 34, 44 are operated to retract _{the rear ends 30 3} ; 40 _{3 of the stop lugs 5; 30; 40.} . In a known solution, the disclosed motion pattern of folding the stop lug occurs by rotating the handle wheel 10. The locking of the stop lug is effected by the rope and the steering wheel or by the weight of the stop lug at one end of the stop lug. In order to allow the unfolded stop lugs to be folded, the cargo deck must first be raised a considerable distance. 1 to 3 and 8 to 10, in order to be able to pull the rope 34 and fold the stop lugs, the cargo deck must be lifted by at least half the thickness of the cargo deck. This is for each cargo deck. It will be about 150 mm, which entails a significant superstructure of the ship that can achieve the desired height for the load on all cargo decks. 1 to 3, the stop lug rests on the anvil 32 in a folded state in the storage position when the cargo deck can move freely in the vertical direction to the intended height. See accompanying Attachment 1.

In Figures 4 to 6, a modified example in which the stop lug is operated to be rotated counterclockwise by the rope 44 to elongate in an interactive state with respect to the stopper 42 and the fixed stop member 33 is shown. Has been. In addition, in the illustrated embodiment, the cargo deck must be lifted a significant distance before the stop lugs can be lifted into the circumferential edge of the cargo deck without stop members 33.

As discussed at the outset of this specification, the fundamental reason for creating the present invention is that it is desirable to be able to reduce the height of the ship caused by the space requirements of the cargo space.

The present invention solves the above problem by the features defined in the claims. According to the invention, it is only required to lift 5 mm to 30 mm for each cargo deck, which leads to significant space savings in the vertical direction.

Accordingly, the main object of the present invention is primarily to solve at least the above problems reliably and efficiently and by simple means that can be operated even by inexperienced personnel.

The object is essentially not only that the locking mechanism supported by the liftable panel is connected via an activation rope with an attached stop lug, the locking mechanism lies between the activation rope and the traction member, and the stop The lug can be actuated to be sent from a storage position inside the panel to a receiving position outside the circumferential edge of the panel or into a cargo panel by means of its own weight and/or an actuating spring connected to the stop lug, and a traction member It is achieved by the support mechanism according to the invention, characterized in that it can be operated to be sent to the opposite position by means of.

With this support mechanism, above all, the above problems are solved, and by distributing and arranging the movable remotely operable stop lugs on the panel on board, above all, the following effects will be:

* It is easier to physically prepare a space for the support of the column, and the support of the column is reduced.

* This support mechanism reduces the cost because the weight of the fittings is reduced.

* In shipyards, it will be more efficient to weld on a fixed support than a large semi-automatic stopper.

* As the column generates less heat, the risk of the column distortion due to heat decreases.

* Reduced sources of error due to less moving parts and fewer ropes/strings.

A movable panel operated at an intended desired height, where it is desirable that the target panel must be stationary and must be reliably held to support significant loads in the form of various types of vehicles. By placing in, many problems are solved. In addition, despite this fact, there has been a tendency to gradually develop a group of stop lugs that are movable and fixed along other parts of the vessel in which the columns and the liftable vehicle deck are arranged to act.

Accordingly, the main object of the present invention is, first of all, to reliably solve the above-described problems in accordance with the above-described features by means of simple, reliable, and economically appropriate means.

Stop members (3, 3A...) for accommodating various types of vehicles on board, and supported at a fixed height and collectively in a vertical direction to a post (4) or other carrier located laterally on the ship. A support mechanism 1 for a liftable panel 2, 2A... having a traction member 5 is arranged to be actuated by means of a traction member 5. A movable stop lug 6 arranged along the perimeter of each panel 2, 2A... is distributed with an attached group of available stop members 3, 3A..., said stop lug Can be operated to engage the desired stop members 3, 3A... According to the invention, which is shown by way of example in FIGS. 2 and 4 to 18, the stop lug 6 is in a separate position FL and a locked position by manual remote operation by the lockable traction member 5. It is movably mounted and arranged to be placed in (LL), and in the detached position (FL), each of the stop lugs 6 is rotated to a turned-in position inside the circumferential edge of the attached panel. Actuated, and in the locked position LL, the perimeter of the panel to which each of the stop lugs 6 is attached in order to mount the panels 2, 2A... to the desired stop members 3, 3A... It is rotated to the locked position LL outside the edge.

Each stop lug 6 is pulled by the attached traction member 5, and the respective stop lug 6 can be over-rotated so that each stop lug 6 can be over-rotated. It is arranged to be actuated by a separate pulling member 5 so as to be placed in the disengaged position FL and the locked position LL by being formed and mounted. This means that the stop lugs are preferably angular and have one angle side 7 mounted to their holder 8 via a shaft not shown. In addition, the stop lug 6 is balanced so as to maintain its equilibrium, that is to say that the stop lug is sent by gravity or by an acting force, for example by means of a spring, to the locked position. In addition, each stop lug 6 is connected with the rope 9 via an attachment 50 and the rope is diverted through a turning pulley 10, 11. Rope 9 extending from the turning pulleys 10 and 11 and the form of a traction and actuation rope extending to the fixed deck 12 of the ship on which the staff 13 controlling the support mechanism 1 is arranged Between the pulling members 5 made of the furnace, a locking mechanism 14 is arranged, which is arranged to be actuated by the pulling and actuating rope 5. Thus, there is one said traction and actuation rope 5 for each support mechanism 1 of each panel 2, 2A...

According to one preferred embodiment, the locking mechanism 14 is formed by an elongated slot 15 of an elongated holder 16, and each end 16A, 16B of the elongate holder has a pull member 5 and A rope 9 is connected, and a locking pin 17 of the stop lug 6 can be accommodated in the slot 15 and can be locked in the locked position LL. The locking pin 17 is preferably located at the upper end portion of the slot 15, is in the form of an end stop of an inverted V-shaped slot 15, and has an intermediate partition 19. It may be lockably received in the angled portion 18 of the slot 15. The locking pin 17 has a thick end portion 20, for example in the form of a washer 20, the thick end portion having a width exceeding the width of the slot 15 at its outer free end And is arranged to hold the locking pin 17 in place in the slot 15. The locking pin 17 is locked with the angled portion 18 of the slot 15 by first simply and efficiently pulling the attached traction member 5 and then tilting the traction member in the direction in which the slot widens. It is released from the bonded state. By immediately loosening the traction member 5, the stop lug 6 is released from its locking engagement with the stop member 3 either by its own weight or by an acting force, for example by a spring not shown.

It is important that the locking mechanism 14 is arranged supported by the respective liftable vehicle deck panels 2, 2A with the rope 9 and the traction member 5 connected as described above. Thus, each of the vehicle deck panels 2, 2A is adjusted by a respective rope 9 and a respective traction member 5.

The holder (8) for the support mechanism (1) is formed of a pair of shape members (21, 22) assembled with an intermediate member, as well as a frame (23) attached for bearing mounting of the traction member (5) These screws 24 and 25 can be loosely connected with the holder 8 on one side 8A. On the side surface of the frame 23, the locking pin 17 is attached to protrude from the frame 23 toward one side.

In order to be able to reduce the weight of the cargo panel, do not make the stop lug too large and heavy, otherwise the stop lug, due to its own weight, is actuated by a spring acting in the direction it would have acted, thereby removing part of the heavy stop lug. Can be replaced. For example, a tension spring is hung between the holder of each stop lug and the free end of the stop lug.

The essence of the present invention according to the above embodiments should be clearly understood from the above contents and the items shown in the drawings. In the following, the function of the support mechanism is described according to the first embodiment of the present invention.

Vehicle deck panels (2, 2A) are arranged on a fixed support stop member (3, 3A...) so that the panels (2, 2A) are in the stowed position and the support mechanism (1) is "locked. When in (locked)", it proceeds as follows:

A. The vehicle deck lifter 13 lifts the panels 2, 2A free from the support of the panel (stop members 3, 3A) (~25 mm, at least)

B. The operator 13 pulls the traction and actuating rope 5 to secure this traction and actuating rope to the locking mechanism at the stopper.

a. When the traction and actuation rope 5 is pulled and sent to the side 60, the movable stop lug 6 is actuated to move freely toward the retracted position FL at the panels 2, 2A.

b. This stop lug 6 can, in the locked position, over-rotate to give a generous clearance.

c. The end of the hand/tow and actuation rope 5 to engage the locking mechanism 14 and the hook when the towing and actuation rope 5 is pulled so that the stop lug 6 is completely inside the panels 2, 2A. Is moved from the side (60) in the direction of the column or web.

d. Then, the pulling force is reduced and by its own weight, the stop lug 6 tries to rotate outward.

e. This causes the traction and actuation rope 5 to be pulled upwards and the hook of the locking plate caught on the shaft 17 of the guide washer 20 at the angled portion 18.

f. The stop lug 6 is now in the "free" position.

C. The vehicle deck lifter 13 can operate the panels 2, 2A downward past the existing fixed upper supports of the stop members 3, 3A.

D. The operator 13 can then move at the exact desired height of the panels 2, 2A and release the stop lug 6 of the panel stopper from the optional support by actuating the attached rope.

a. This is accomplished by the operator 13 pulling the traction and actuation rope 5 downward.

b. In doing so, the stop lug 6 is over-rotated and the locking mechanism 14 and its hook are released, i.e., either by its own weight or by another force, for example by a spring force from the placed spring, The stop lug 6 will rotate outward.

c. By directing the free end of the rope in the post 4 or web essentially straight down, the locking pin 17 of the frame 23 is released from the elongated slot of the locking mechanism.

d. The stop lug 6 now rotates outward by its own weight and pulls the traction and actuation rope 5 upwards.

e. When the stop lug 6 is in the protruding position, the locking mechanism 14 slides and is guided in the elongated slot 15 of the locking mechanism and then hangs freely.

E. The operator 13 can feel, see and hear that the stop lug 6 is out, visually and audibly, as well as tactile feedback from the traction and actuation rope 5.

F. The operator 13 can now safely lower the panels 2, 2A onto the fixed supports 3, 3A of the panels.

Thus, the stop lug 6 is arranged to be actuated to be rotated to its intended locking position LL by its own weight, by spring force actuation, or in some other way, but from below, for example Separation position FL by remote actuation by means of a traction member 5 arranged lockably, in a manner specified by a traction member 5, which may consist of a rope actuated, for example from a fixed cargo deck of the ship. Is sent to The holder 8 receives a rotatably mounted stop lug 6 and the traction member 5 is connected to the stop lug 6 via a fastening ear 50. The intermediate locking mechanism 14 to which the traction member 5 is connected is, in the locked position, by means of a locking pin and a locking hook shown in the figure, to the object fixed according to the above example. It is arranged to be fixed. The traction member 5, for example, by prior art from the sailing boat industry, i.e. by means of a number of clamp cleats in which the actuating rope is pulled between a pair of rotatable fastening members. Is simply locked by simply loosening it. In one direction of movement of the actuating rope, a turnable and grooved clamping member resists the actuating rope, while pulling the actuating rope cross-direction away from the clamp cleat. It will loosen the actuating rope from the clamp cleat so that the actuating rope can move freely again.

20-26, instead of a rotatably mounted stop lug 6, a displaceably spring-actuatable mounted stop lug 806, i.e. A piston-like bar supported by the target movable panel 2 in the support 850 may be disposed. The support 850 also supports the holder 808 according to the first embodiment, and a corresponding locking mechanism 14 is supported and attached to the support according to the first embodiment. In this connection, an activation rope 9 extends from the locking mechanism 14 to the stop lug 806 and is fixedly connected to the stop lug via an attachment 851. A spring 853, preferably a tension spring, is arranged to be connected with the stop lug 806. This spring 853 closes the stop lug 806 after the attached locking mechanism is loosened so that the rope 9 can move along the stop lug 806 in the movement provided by the spring 853. It is actuated to be pulled towards the holder 808 and the panel 2 which can be supported by the stop lug 806. When the stop lug 806 moves back and forth in a protruding receiving position with a protrusion protruding from the inside of the holder 808 and the panel, another spring 852 is provided to allow for adjusting possible longitudinal movement of the stop lug 806. ) May be supported by the attachment 851. In this regard, the stop lug 806 is essentially horizontal when the stop lug 806 is actuated by the spring 853 after the attached locking mechanism 14 is loosened. It is formed and mounted to move in the direction from the locked position LL to the detachable position FL into the movable liftable panel 2 attached. Each stop lug 806 is connected to the activation rope 9 via an attachment 851, which extends past the turning pulleys 810, 811 to the locking mechanism 14. In another respect, the support mechanism is according to the example. In other words, a traction and actuation rope 5 or other traction member is connected with the locking mechanism 14 and extends to the fixed deck of the ship. The stop lug 806 has a portion 855 supported by a reel 856 or some other rotating member, and the reel 856 or some other rotating member is a substratum of the stop lug 806. To reduce friction and displace the stop lug along the base layer. The stopper 857 of the stop lug 806, in the loaded state of the panel 2 and the stop lug 806, is caused by possible external forces, inward of the stop lug towards the panel 2 It is arranged to stop by touching the anvil 858, which prevents return to the direction.

By pulling the rope 5, the locking mechanism 14 is operated so that the function of the locking mechanism becomes the same as in the first embodiment, but the stop lug 806 is, unlike the first embodiment, the panel ( 2) is pulled. In order for the support mechanism 101 to operate, it is required that the liftable panel 2 be lifted to a minimum, whereby the desired object is reliably achieved.

In FIGS. 17-19 an example of a remote-controllable mechanism 201 is shown in which a ^{rotatable stop lug 306 can be operated remotely from a central operation unit 380 of the panel 2 n.} For example, via the remote control 390, which is not described in more detail, the operation unit 380 moves the movable stop lug 306 into the inside of the circumferential edge 400 of the attached liftable panel. As it can be operated to pull or release the stop lug 306, the stop lug may be engaged at the bottom of it with a mating stop member at a desired height.

The piston-type cylinder 500 is connected to a common connection part 540 through a traction member in the form of a block 501 and a rope 590, and when the piston-type cylinder 500 is operated, the above-described All stop lugs 306 are pulled together in the direction of arrow 600 at the same time as a group or released in the direction of arrow 700 at the same time.

Of course, the invention is shown in the accompanying drawings and is not limited to the embodiments described above. Various modifications can be realized without departing from the scope of protection of the present invention, as defined in the claims, particularly with respect to the nature of different parts, or by using equivalent techniques. For example, in the form of a spring member arranged to be actuated by a locking mechanism other than that shown and described herein, for example a rope or other traction member operable at a distance from the subject panel 2, 3 Or other types of locking mechanisms could be used.
