Description

  The invention includes actuator means associated with each hatch cover in a mechanism for operation of a movable ship hatch cover that is displaceable between a closed and open position and between an open and closed position, respectively. Relates to the device.

  The mechanism which operates the movable hatch cover which can displace a ship according to the above is shown by patent document 1 and patent document 2 as an example, respectively. The mechanism works with machine components, but usually requires multiple hydraulic jacks, and considerable work is required to define the conduit from the pumping station to the jack. Oil spills may occur, and in that case, there is a risk that the staff on the ship will slip their feet. Also, many parts are required for the mechanism to work perfectly.

By eliminating the hydraulic piping, the following components and operations will not be required. In other words, it is not necessary to understand complicated hydraulic equipment, hatch combing and partition hole drilling, pipe foundation, hydraulic pipe, coupling, clamp, flushing, considerably less hydraulic oil, paint and paint preparation Cost savings, installation work, less component transportation and handling, no maintenance work, and crews do not necessarily need to understand and perform complex hydraulic equipment service and maintenance.

  The main object of the present invention is therefore mainly to solve the above problems in a simple, efficient and economical manner.

  The above object is a device according to the invention in which each hatch cover is electrically operated directly or indirectly by means of an electric motor and is closed on either side of the lateral limiting edge of the hatch. It is rotatably mounted such that it can be removably interconnected with the respective hatch cover for the operation of movable ship hatch covers that can be displaced between open and closed positions, respectively. This is achieved by a device which is essentially characterized by the fact that a separate actuator element is provided.

  A new simple lift side rolling hatch cover is designed to be a reliable and cost-effective hatch cover for bulk carriers. This applies to all aspects of the hatch cover, such as design, purchase, manufacture, installation, maintenance during operation, and the like. These aspects affect the cost of all relevant parts. In the design work, it aims to reduce the number of parts and assemblies handled. This has been done without compromising any well-established standard of ceremonies.

  A hydraulic cylinder lifting mechanism is installed in the center of the longitudinal hatch combing on the starboard (SB) and port (PS). This mechanism acts on one of the panels, and on the other panel is a fork link mechanism. Both panels are lifted to the rolling position by being released from cleat tightening at the same time. The hydraulic oil is supplied by a local minipump unit that is installed close to the mechanism and is connected to the hydraulic cylinder by two hoses. In order to minimize the number of components and eliminate the electric valve, the rotation of the electric motor is reversed when the panel is raised and lowered. Together with the electric motor gear drive mechanism, this realizes an overall electrical system.

  There is no electric valve built into the hydraulic circuit. The forward and backward operations are performed by changing the rotation direction of the electric motor.

  When the panel is lifted to the rolling position, the electric gear motor driven winch / wire structure opens both of the hatch cover panels simultaneously. The wire drive structure is installed only on the stern. The puller wire can be 16-24 mm or more, and the interconnect wire between the two panels can be 24 mm in order to reduce wire stretch and keep the distance between the two panels more constant. Or it can be more. (A special interconnect wire may be used in front of the hatch cover.)

  The panel is lifted 65 mm by the lifting mechanism. One sealing gasket is attached and the nominal compression is 15 mm.

  In order to reduce the friction between the hatch combing and the panel, particularly during tightening / releasing by cleats, a support pad is incorporated. These pads also guarantee a long fault-free service life. The lift / fork mechanism is designed to easily fit hatch combing.

  In order to provide easy installation, the top surface of the hatch combing will be coplanar and no drilling for wheels or cleats will be required. This is of course possible if a lower rail is required by the yard / owner. For reasons of weight and size, different sized gear motors and lifting mechanisms may be required. In order to secure the panels together in the closed position, a sturdy manually operated pin is fitted into the CL. Alternatives that are compatible with the center link to the lifting mechanism are possible.

  The operating time for a complete open or closed sequence is about 5 minutes. The operation of the hatch cover will be done by a fixed or portable electric control device, which can be combined and used at a suitable position on the hatch combing. One electrical cabinet will be supplied to each hatch. Electric gear motors and brakes prevent solids from entering the housing, complete protection from charged or moving parts, and prevent dust and liquids from entering the housing. Water from rough seas will not enter the device.

  The operating device is designed with a maximum trim of 3 °, and in the basic design, the two panels are operated simultaneously. The default position of the operating device is on the PS. The flanged wheels on the panels and the guide rails on the hatch combing are placed towards the stern. Flangeless wheels are placed towards the bow. Panel, hatch combing and slope (ramp) steel structures are not part of this project. These items are being studied in separate studies.

  Hereinafter, the present invention will be schematically described with reference to the drawings. 1 and 1A show the operation of the movable ship hatch covers 3, 4 that are displaceable between a closed position I and an open position II and between an open position II and a closed position I, respectively, according to the present invention. A device 1 is shown that includes actuator means associated with respective hatch covers 3, 4 in a mechanism for the purpose.

Each actuator element 12, 13 is forced into a receiving ready position III (see illustration E in FIG. 11) adapted to receive a connecting member 20, 21 coupled to a respective hatch cover 3, 4. It is arrange | positioned so that it may transfer. In the position III, the reception is performed, for example, in the form of a weight at one end with the aim of the respective actuator element 12, 13 being automatically transferred to the intended connection ready position III. Can be done by the fact that it is actuated or unbalanced.

  Each actuator element 12, 13 has a slot-shaped elongated recess 29, 30 at its respective end 26, 27, in which the coupling member 20, 21 is guided more efficiently, respectively. And in order to allow reception, the opposite arm ends 26, 27 preferably have shorter 26A, 27A and longer arm end positions 26B, 27B, respectively.

  Attachments 32 and 33 projecting in the downward direction 31 of the respective hatch covers 3, 4 are respectively lateral portions 8, 9 and 10 of the respective hatch covers in the vicinity of the respective closing edges 34, 35 of the hatch covers. , 11 respectively. The type of attachment secures each end 38, 39 of the tow rope loop 6 at its corners 40 and supports the connecting member 20 at its free branch end 41 facing the closing edge 34, 35 of the hatch cover. For this purpose, an L-shaped side plate 32 having attachments 36 and 37 is used. In addition, there is a downward plate 33, such as a straight vertical material, intended to fix the ends 42, 43 of the tow rope loops that meet each other. Thereby, the connecting member 21 of the hatch cover 4 is directly supported by the hatch cover 4 and preferably projects outwardly on the ear-shaped fastener 5 at the front edge 4A of the hatch cover. A plurality of bars 44, 45 connected in a line so that the tow rope loop 6 can be manually adjusted function between the attachments 32, 33 and the end portions 39, 46 of the rope loop.

The additional portion 6 </ b> B can be provided so as to be wound around the rope drum 15.

  The hatch covers 3 and 4 are supported by a rotating member such as a wheel 49, for example, and the rotating member is disposed along the mutually facing edge side surfaces 8, 9 and 10, 11 of the closeable opening 7 of the subject. 50 so as to travel on the road.

  The track 50 has a recess 51 in the vicinity of the closed position of the hatch cover, and the hatch covers 3, 4 cooperate with a lifting / ratchet member 53 provided in the part of the opening facing outward as viewed from each other. Therefore, the stoppers 52 are provided in the portions facing outward when viewed from each other.

  In FIGS. 14 to 16 and FIGS. 17 to 19, two variations of the kick-off mechanism having the above-described function are shown. In accordance with the example of the first embodiment, the kick-off mechanism 53 is directly actuated by a hydraulic piston 54 having a drive mechanism disposed from a small pumping station 55 near the kick-off mechanism 53. But in that regard, it is necessary to define some pipeline for the hydraulic part. Alternatively, the jack may be operated electrically. Please refer to FIG. 14 to FIG. 16 and FIG. 7 to FIG.

  The variant shown in FIGS. 17-19 includes an over-center mechanism 60 comprised of a lever arm or the like that is actuated by a piston 54 and driven by a pumping station 55.

  The function of the present invention will be apparent from the above description and the drawings. Between the hatches 3 and 4 and the surrounding edges there is an elastic gasket 61 which is squeezed and sealed when the hatches 3 and 4 are placed in place.

  The hatch cover 103 shown in FIG. 21 is arranged so as to be able to travel by a rack and pinion drive mechanism 175, and the rack and pinion drive mechanism 175 is a rack 176 attached to the hatch cover 103. And is arranged so as to extend along one side of the hatch cover 103 and is attached thereto. A pinion 177 driven by an electric motor 178 via a gear 179 is disposed in hatch combing. The slave wires are attached to one side 103 of the rack and pinion driven hatch, and are arranged so as to cover and expose the hatch opening 107 of the ship together with the first hatch cover 103. The second hatch cover that is not running travels around the return gear as a loop. In addition, a pivotally mounted actuator element is also provided, which can be removably interconnected with the respective hatch cover via a coupling member as described above. The drive of the electric motor 178 activates the pinion 177 and drives the rack 176 and hence the corresponding hatch cover 103 in the desired direction. The slave wire operates so that the second hatch cover is driven in the reverse direction because the slave wire is attached to the second hatch cover. The function of the oscillating arm-like actuator element is the same according to the example embodiment of the device 1 for lifting the hatch cover and starting the movement of the hatch cover as previously shown and described.

  Alternatively, one or both of the hatch covers can be driven by separate racks. The opposite side of the hatch opening 107 can have a slave wire that conforms to the above and has the same function.

  Of course, the present invention is not limited to the embodiments described above and shown in the accompanying drawings. Modifications may be made without departing from the protection scope of the present invention as defined in the claims, particularly with respect to the various component types, or by using equivalent techniques.
