Definitions

  • a device at hatch covers
  • the present invention relates to a device at a mechanism for the operation of displaceably movable hatch covers of ships between a closed and an open position and between an open and a closed position, respectively, and that comprises actuating means connecting with the respective hatch cover.
  • Mechanisms to actuate displaceably movable hatch covers of ships according to the above are shown as examples in WO 2005/025977 Al and WO 02/090175 Al, respectively.
  • Said mechanisms work with mechanical elements, but normally a plurality of hydraulically operated jacks are required, a con- siderable work being needed for the pipe routing from pumping stations to jacks in question and that leakage of oil from the same may occur with the risk of slippery substrate for the staff onboard. Many parts are also required for the mechanism to work satisfactory. By avoiding hydraulic piping the following component and work will not be required:
  • the main object of the present invention is primarily to solve said problems in a simple, efficient and economically satisfactory way.
  • a device that substantially is characterized in that the respective hatch cover is electrically operated directly or indirectly by an electrical motor, and that on either side of the lateral limiting edge of the hatches, there is provided a turnably mounted actuating ele- ment, which is detachably interconnectable with the respective hatch cover, for the operation of the displaceably moveable hatch covers of the ship between a closed and an open position and between an open and a closed position, respectively.
  • the new simple lift side rolling hatch cover is designed to be a reliable and cost effective hatch cover for bulk carriers. This will apply in all aspects of the hatch cover such as design, purchase, manufacturing, installation and in service maintenance. These aspects influence the cost for all involved parts. In the design work, it has been aimed for a reduction of the numbers of parts and assemblies to be handled. This has been done without any compromises to the well established standard of the equipment.
  • a hydraulic cylinder lifting mechanism is fitted in the middle of the longitudinal coaming on starboard (SB) and portside (PS) .
  • This mechanism acts on one of the panels and by a fork link mechanism in the other panel.
  • the panels are simultaneously uncleated and lifted into a rolling position.
  • Hydraulic oil is supplied by a local mini pump unit fitted close to the mechanism and connected with two hoses to the hydraulic cylinder.
  • the rotation of the electric motor is changed when lifting and lowering of the panels take place. Together with the electric motor gear drive, this means an overall electric solution. There are no electric valves incorporated in the hydraulic circuit.
  • the back and fore operations are performed by changing the rotation of the electric motor.
  • an electric gear motor driven winch/wire arrangement opens both the panels of the hatch cover simultaneously.
  • the wire drive arrangement is fitted aft only.
  • the pulling wires can be between 16 and 24 mm or more and the interconnection wire between the two panels can be 24 mm or more in order to get less wire stretch and keep the distance between the two panels more constant. (An extra interconnection wire may be used on the fore side of the hatch cover) .
  • the panels are lifted 65 mm by the lifting mechanism. A single seals gasket is fitted and the nominal compression is 15 mm.
  • sup- port pads are incorporated. These pads also ensure long trouble-free service life.
  • the lifting and fork mechanisms are designed to be easy to fit to the coaming.
  • the top of the coaming is in one plane and no cuts out for wheels or cleats will be required. If a lower rail is required by the yard/owner, this is of course possible. Due to weight and size, different sizes of the gear motors and lifting mechanism may be required. To secure the panels to each other in the closed position, manually operated heavy duty pins are fitted in CL. An alternative solution could be to fit over centre links to the lifting mechanism.
  • the operation time for a complete opening or closing sequence is approximately 5 min.
  • the operation of the hatch covers will be done by a fixed or a portable electric control, which can be connected and used on a preferable location on the coaming.
  • One electric cabinet will be supplied for each hatch.
  • Electric gear motors and brakes protect against penetration of solid objects into the housing and complete the protection from live or moving parts, and also protect against penetration of dust and against penetration of liquids into the housing. Water from heavy seas will not enter the device.
  • the operating equipment is designed for a max trim of 3°, and in the basic design, the two panels are operated simultaneously. The default location of the operating equipment is on the PS.
  • the flanged wheels on the panels and the guide rails on the coaming are fitted aft. Wheels without flanges are fitted fore.
  • the steel structures of the panels, coaming and ramps are not a part of this project. These items have been investigated in another study.
  • Fig. 1 shows a schematic plan view of ship's hatches in pairs in a closed position
  • Fig. IA shows also a schematic plan view of ship's hatches in pairs in an open position
  • Figs. 2-6 show side views of the ship's hatches actuated by a mechanism according to the invention and brought into different displacement positions
  • Figs. 7-8 show edge views of ship's hatches
  • Figs. 9-10 show functional diagrams of the actuation of the ship's hatches by the mechanism according to the invention in a closed position and an opening position, respectively,
  • Fig. 11 shows actuating elements, included in the mechanism, in different actuating positions and the cooperation with the respective hatch,
  • Figs. 12-13 show a loop-shapedly drawn and driven pulling rope included in the mechanism as seen from the side and from above, respectively
  • Figs. 14-16 and Figs. 17-19, respectively, show examples in pairs of different lifting and actuation members for the hatches
  • Fig. 20 shows an integrated driving and rope- supporting roll assembly for the pulling-rope loop, as seen from the side, and
  • Fig. 21 shows an alternative embodiment example of the operation of hatch covers.
  • a device 1 at a mechanism according to the invention for the operation of the displaceably movable hatch covers 3, 4 of a ship 2 between a closed position I and an open position II and between an open position II and a closed position I, respectively, and that comprises actuating means connecting with the respective hatch cover 3, 4, is shown in the drawings in Fig. 1 and Fig. IA.
  • the respective hatch cover 3, 4 is connected to a loop-shapedly running, driven pulling rope 6.
  • a pulling rope may be composed of a wire, of metal or plastic, a strip, a chain or a combination of said pulling members.
  • Such a pulling rope may be provided on at least one side A of the appurtenant closable opening 7 of the two hatches 3, 4.
  • a driven pulling rope may be provided on one side of the hatches 3, 4, while a pulling rope that only runs freely is provided on the other side of the hatches 3, 4.
  • Such an additional slave rope provided on the opposite side of the hatch allows to obtain non-even running of the drive and the movement actuation of the hatches.
  • a turnably mounted actuating element 12 and 13, respectively which is detachably intercon- nectable with the respective hatch cover 3, 4 at desired occa- sions.
  • Said pulling rope 6 is driven by an electrical motor 14 that is arranged to actuate the pulling rope 6 via a rope drum 15 to open the two hatch covers simultaneously in directions 16, 17 opposite each other and shut the two hatch cov- ers simultaneously in directions 18, 19 opposite each other, respectively.
  • the hatches may be run by means of a rack-and-pinion drive that consists of a rack placed along the side and hatch half of one hatch, and of a pinion that is driven by an electric motor and a gear that are placed in the coaming, as well as of a slave wire that is attached to the rack-and-pinion driven hatch half and that runs as a loop to the slave part.
