Description

  The present invention is a device of a mechanism for operating a movable hatch cover portion of a ship from a closed position to an open position, and from an open position to a closed position, each of which can be moved by the force of an operating cylinder type hydraulic jack. It relates to a device comprising a pivoting link element movably attached to a hatch cover part.

  The mechanism that opens and closes and locks the hatch cover portion on the ship in question here is usually composed of a hydraulically actuated piston-cylinder jack or a hydraulic prime mover and a chain. The aforementioned hatch cover portion is thus smoothly moved to the desired position along the track for the intended purpose.

  As a solution for achieving the actual opening and closing and locking of the hatch cover part, a plurality of linked pivot link arms have been previously disclosed. A pivoting link arm is used to move the hatch cover parts in question in the direction away from and close to each other with the aid of a gripper to open and close the entrance to the lockable cargo hold on board. Operated with a common jack. In this case, it is necessary to provide a separate locking device.

  Further, for example, a mechanism for operating a hatch cover portion on a ship is also disclosed in Patent Document 1 in advance. For this purpose, a pair of gear parts is used. The gear portion can be actuated by a jack that pivots the gear portion to a desired position. However, although the aforementioned locking device is operatively connected between the jack and gear portion, a special locking device is required to hold the hatch cover portion in place in the closed position.

The previously disclosed solution is as a general unit that is complex to manufacture components and does not require special adaptation between the deck and the frame in order for the mechanism to function reliably, i.e. not a dedicated unit. It cannot be installed easily.
International Publication No. WO 02/090175 A1

  The main object of the present invention is therefore firstly to solve the above-mentioned problems in a particularly simple and effective manner.

  This object is achieved by a device according to the invention. Such a device means that a plurality of pairs of pivotal link arms mounted on a common part of the ship are attached at one end of each link arm to the corresponding hatch cover part, preferably by an interlocking connection, The other end of the link arm is attached to a split link (11) that can be moved by the force of the jack described above, and both the link arms are connected to each other by a distance piece. When force is applied by a jack, the two link parts are forced to pivot from the lower retracted lock position to the open position, and in the open position, each hatch cover portion attached to the link arm is moved to the upper deployed position. It is an apparatus characterized by being held.

  The function of this mechanism is to raise / operate and lower / operate the two hatch cover parts from the closed position to the open position, and conversely from the open position to the closed position. And locked in the closed position. This new solution is a further development of the previously disclosed solution. Comparing that feature with the previously disclosed solution, the link corresponds to the gear rack portion, but the manufacturing process required in the present invention is simple. The mechanism of the present invention is composed of a large number of links and is lighter than the gear rack portion. The entire mechanism can be assembled and installed as a unit. At this time, adjustment between the deck and the frame is not necessary.

  The device 1 of the mechanism 2 that operates the movable hatch cover portions 3 and 4 of the ship from the closed position A to the open position B and from the open position B to the closed position A, respectively, with the force of the operating cylinder type hydraulic jack 7 The device 1 comprising pivoting link elements 5, 6 movably attached to each hatch cover part 3, 4 which can be moved is pivotable which can interact in pairs. Link arms 8 and 9 are provided. Each hatch cover portion 3, 4, which is the subject here, usually extends over the entire longitudinal range and cargo width of the ship, so only a small part is schematically shown in the figure. The aforementioned link arms 8 and 9 are supported on the common part 10 of the ship and are attached to the corresponding hatch cover parts 3 and 4 by so-called meshing connection at one end 8A and 9A of each link arm. The link arms 8 and 9 are attached to the divided links 11 at the other ends 8B and 9B of the link arms. The link connecting portion 11 can be moved by the forces FF and FB of the jack 7 described above.

  Both link arms 8 and 9 are also connected to each other by a distance piece 12. The link arms 8 and 9 are thus pivoted from the lower retracted lock position C to the open position D by the forced interaction of both parts 13 and 14 of the split link when a force is applied by the jack 7. In the open position D, the hatch cover portions 3 and 4 attached to the link arms 8 and 9 are held at the upper deployed position B.

  The aforementioned split link 11 is formed by a pair of interacting articulated arms 13, 14 as shown in the figure, and the articulated arms 13, 14 are common to one end 13A, 14A of each articulated arm. The joints 15 are connected to each other in a multi-joint manner. Each of the two articulated arms 13, 14 is connected to its corresponding link arm 5, 6 via the joints 16, 17 in an articulated manner at a distance from the aforementioned common joint 15.

  The aforementioned common joint 15 is arranged at a given angle X so that it can pass through an imaginary line 18 connecting the joints 16 and 17 which are a part of each of the link arms 8 and 9. When the common joint 15 passes the virtual line 18, so-called over-center lock of the two links 8, 9 is achieved in conjunction with it, and when the common joint 15 that has passed the virtual line 18 returns to its original state, The lock can be released in conjunction.

  Both link arms 8 and 9 are pivotally mounted on the ship via joints 19 and 31, respectively, and are supported by a common support portion 10. The aforementioned support part 10 is preferably formed by long beams and / or plates 23. As a result, the mechanism 2 is supported as a unit 24, and the unit 24 is easily transported on the deck of the ship along the frame top 22 at the opening of the frame 21 without requiring complicated operations. Can be securely attached.

  A part of one articulated arm 13 is an oblique pivoting arm 25 attached directly or indirectly to the jack 7 described above. The aforementioned oblique pivoting arm 25 is arranged to extend with an obtuse angle Z of preferably 100 ° to 140 ° with respect to the remaining part 20 of the corresponding articulated arm 13. The joint 16 between the aforementioned articulated arm 13 and one of the link arms 8 is located near both the pivoting arms 20 and 25 of the aforementioned articulated arm 13 for this purpose. As a result, the desired unlocking and locking of the mechanism 2 can be achieved simply by expanding and contracting the jack 7.

  The two link arms 8 and 9 are also connected to each other via a rigid arm 12. The rigid arm 12 acts as a distance piece and is connected in an articulated manner to the fixed lugs 27, 28 of each link arm 8, 9 at one end 8B, 9A of each link arm, as illustrated in FIG.

  The link arms 8, 9 preferably have a triangular shape such that the joints 29, 30; 16, 17 for the hatch cover parts 3, 4 and the articulated arm 13 are located at their respective ends.

  As can be clearly seen from the perspective views of FIGS. 2 and 3, the link connecting parts 13 and 14 are doubled, and each of the pair of links is located on both sides I and II of the two link arms 8 and 9. .

  In order to be able to easily install the mechanism, the aforementioned mechanism 2 is assembled as a unit arranged so that it can be installed at the place of use simply by being attached to the ship by welding and / or bolted joints. The above-mentioned jack 7 is supported by the above-described unit 24, and is pivotally attached at one end 7A to the pivot 32 supported by the above-described plate 23 and / or the beam 10, and is pivotally attached to the pivot 26 at the opposite other end 7B. ing.

  The present invention is of course not limited to the embodiments shown in the above description and the accompanying drawings. Modifications are possible, particularly in connection with various components or using equivalent techniques, without departing from the scope sought for protection as defined by the claims.
