Definitions

  • This invention relates to a device for warping and mooring ships with winching means comprising two grooved drums for hauling in and paying out a rope, and having stowing means for accommodating the rope end which is paid off from the winching device and is distal with respect to the load side and on which a pull S is applied.
  • Warping and mooring devices of this general type are already known, particularly on large ships.
  • a relatively large pull S can be applied to the load-side end of the rope by means of the grooved drums over which the rope is guided so as to hug the drums in a figure-eight configuration.
  • the rope which is paid off from the grooved double drums on the side which is distal with respect to the load side is supplied to a stowing drum. The purpose of the latter is also to apply the necessary pull S to the rope.
  • the device according to the invention is characterised by the application of the S pull to the end of the rope by the winching device itself. According to the invention this can be achieved in different ways, more particularly by increasing the friction of the rope in one or more rope grooves of the drum on the side of the winching device remote from the load side.
  • the invention proceeds from the fact that a pull S must necessarily be applied in such winching devices with grooved double drums on the rope end which is distal with respect to the load so that the necessary traction or pull S can be produced in accordance with the principles governing the reeving on the load side.
  • the pull or traction S on the remote side of the drums is applied to the rope by the drums themselves.
  • the surface of the drum grooves nearest to the free end of the rope is so constructed as to permit the application of a suflicient S pull.
  • the invention also relates to the drive of the grooved drums.
  • the drums are driven by a friction wheel transmission, namely by means of two friction wheels which are disposed at the ends of the drums and are thrust against each other and are driven by a common motor.
  • the driving force of the motor is therefore merely transmitted to one drum and from there via the friction wheels to the second drum.
  • the special feature according to the invention is the provision on one side of the apparatus of a spring by means of which the friction wheels disposed on said side are thrust against each other.
  • the thrust force of the spring is transmitted to adjacent friction wheels via a connecting linkage.
  • the construction of this arrangement is not only very simple, but is also achieves a favorable force distribution which prevents substantial or large forces from being transmitted via the foundations of the bearing pedestals for the grooved drums into the ships structure.
  • FIG. 1 shows a diagrammatic plan view of the device according to the invention
  • FIG. 2 shows a side view of FIG. 1 with the stowing device disposed below deck
  • FIG. 3 shows a cross-section through a drum in the zone of an S rope groove in an enlarged scale
  • FIG. 4 shows a cross-section IVIV of FIG. 3 through a groove section of an S groove in an enlarged scale
  • FIG. 5 shows a perspective diagrammatic view of the bearing system for the grooved drums
  • FIG. 6 shows a side view of the winching device.
  • the most essential component of the system comprises a winching device 10.
  • This comprises two drums 11 and 12 which are driven in counter-rotation.
  • the said drums are provided with grooves 13 disposed at a distance and parallel from each other and in which a finite rope l4-is adapted to run.
  • the drums 11 and 12 are repeatedly hugged in the region of the grooves 13 in a figure -eight configuration.
  • the S end 14a of the rope 14 disposed nearest to the load passes at one end onto the drum l1 and leaves the drum by its end 14b. As may be seen in FIG. 1 the load-side S end can run in different directions.
  • the S end 14b which is distal with respect to the load is stowed in a suitable manner.
  • the S end 14b passes into a collecting basket 16 which is disposed below deck 15.
  • the rope 14 is deposited in the basket in loose loops or turns.
  • a rope guide can be provided at this position if necessary.
  • a specific amount of guiding is obtained by a rope guide tube 17 which guides the rope to the longitudinal median axis of the collecting basket.
  • a rope pull S must be applied to the rope end 14b so as to produce a corresponding rope pull S on the load side.
  • the relationship between S and S is defined by the formula for reeved transmissions, namely:
  • the necessary rope pull 8 in the present case is applied to the rope 14 by the winching device 10.
  • the groove 13a on the drum 11 situated nearest to the S end 14b of the rope 14, but where appropriate also the preceeding groove 13b on the drum 12, is constructed in a special manner so that the rope 14 is provided with additional adhesion at that position.
  • This adhesion in turn produces the required rope pull S
  • the affected rope grooves are provided with ball head protuberances 18 and 19.
  • Advantageously two rows of protuberances l8 and 19 are provided which are disposed on both sides of the longitudinal median plane 20 of the affected groove or 13b in the peripheral orientation at distances from each other.
  • the spacing between protuberances 18 and 19 from the longitudinal median plane 20 is preferably 45.
  • the groove floor 21 in this case is constructed in the shape of a circular arc while the distance between the flanks 22 and 23 is such that the rope 14 engages with the protuberances l8 and 19 on the groove floor.
  • a thrust device in the form of a thrust roller 25 which is biased by a compression spring 24 or by other means can be used in addition to or in place of the previouslymentioned means for producing the rope pull S
  • a thrust roller 25 of this kind is appropriately provided at least in the region of the S side groove 13a. It thrusts the rope 14 against the groove floor 21 thus producing the desired engagement between the rope and the protuberances 18 and 19.
  • the thrust applied by the roller 25 is preferably 100 150 kg.
  • the drive for the winching device is so constructed that the drum 11 is driven through a drive shaft 26 by means of a motor which is disposed in a casing 27, the direction of rotation in the illustrated embodiment being clockwise.
  • the drive is transmitted by the drum 11 to the drum 12 through friction wheels 28 and 29 as well as 30 and 31.
  • the friction wheels 28-31 are thrust against each other by the rope 14 which hugs the drums l1 and 12, and an additional thrust force is also applied as described below.
  • the drums 11 and 12 are joined to each other in the region of the friction wheels 30 and 31 by means of a tie bar 32.
  • One end thereof is moored via a joint 46 on a bearing pedestal 33 of the drum 11.
  • the other end of the tie bar 32 is adapted to slide longitudinally in a sleeve shaped guide 34.
  • a compression spring 35 bears on the guide 34 on the side which is distal with respect to the bearing pedestal 33.
  • the other end of the compression spring 35 bears on a support plate 36 which is disposed at the end of the tie bar 32.
  • the guide 34 with compression spring 35 and support plate 36 is non-rotationally joined to the shaft 38 of the drum 12 by means of a rigid arm 37.
  • a defined prestress of the compression spring 35 causes it to transmit a contact pressure to the guide 34 which is movable relative to the tie bar 32.
  • the contact pressure is transmitted via the am 37 to the shaft 38 and therefore to the drum 12 which is thus thrust by means of the friction wheels 29 and 31 against the friction wheels 28 and 30.
  • the additional thrust force of the compression spring 35 which is disposed on only one side of the drums 11 and 12, is transmitted by means of a separate linkage to the friction wheels 28 and 29 which are distal or on the other side.
  • the drum 12 is movably supported by means of rocker supports 39 and 40 which are joined to the ends of the shaft 38.
  • the rocker supports 39 and 40 are mounted by means of joint bearings 41 and 42 on a foundation.
  • the drum 12 is supported by means of rotary bearings 43 and 44 on the shaft 38.
  • the end of the shaft 38 nearest to the rocker support 39 is coupled via a rotary bearing 45 to the rocker support 39, the opposite end of the shaft 38 being rigidly connected to the rocker support 40.
  • the contact force applied by the compression spring 35 is transmitted to the shaft 38 via the arm 37 which is rigidly coupled thereto. Accordingly, the friction wheel 31 is thrust directly on to the friction wheel 30. The contact force is also transmitted to the oppositely disposed friction wheel 29 via the shaft 38 which thus operates as a torsion bar, the friction wheel 29 being thus pressed with the same force against the friction wheel 28.
  • a relatively simple construction utilizing only one compression spring 35 therefore permits the friction wheels to be uniformly thrust against each other without any undesirable loading being applied to the foundation.
  • the construction of the thrust device which is diagrammatically illustrated in FIG. 5 is shown in FIG. 6.
  • the tie bar 32 constructed as a rod, is provided with a joint 47 disposed nearest to the guide 34, as also shown in FIG. 5, so as to avoid forcing.
  • the rocker supports 39 and 40 as well as the joint bearings 41 and 42 are specially constructed in this case.
  • the joint bearings comprise a bearing pedestal 48 of suitably small dimensions, the top of which is connected to the rocker support 39 by means of a support lug 49 and a pin joint 50.
  • rocker support 40 and the joint bearing 42 are identically constructed, the only difference being that the rocker support 40 at that position is not mounted on the shaft 38 by means of a hearing which corresponds to the rotary bearing 45 but is nonrotationally joined to the said shaft.
  • a winch apparatus for warping and mooring ships including two grooved drums l 1, 12 for hauling in and paying out a rope 14 on input and output sides, respectively, and having stowing means 16 for accommodating the rope end 14b which is paid off from the output side of the winching apparatus and which is distal with respect to the load or input side, and on which a tractive pull S is applied, the improvement characterized by means incorporated directly in the winch apparatus for applying the tractive pull on the rope end at the output side, one of the drums being driven from the outside and the drive being transmitted by pairs of friction wheels to the other drum, the friction wheels being additionally thrust against each other by spring force, such that the friction wheels 28, 29, 30, 31 are joined to each other by tie bars 32 which are retained under stress in the sense of pressing the friction wheels 28-31 against each other by means of compressing springs 35.
  • Apparatus according to claim 1 characterized in that only the pair of friction wheels, which are distal with respect to the input side are pressed against each other by means of a spring-biased tie bar 32, the contact force being transmitted by the friction wheels 30, 31 to the adjacent friction wheels 28, 29 by means of a linkage 37, 38.
  • Apparatus according to claim 3 characterized in that the thrust force of the compression spring 35 can be transmitted to a guide 34 which is slideable on the tie bar- 32 and is connected to the shaft 38 through a rigid lever 37, the end of the shaft 38 nearest to the spring 35 being connected via a rotating bearing 45 to the associated rocker support 39.
  • stowing means for accommodating the rope end which is paid off from the winching device and is distal with respect to the load side S wherein a pull S produced by the winching device is applied, the improvement characterized in that one or more rope grooves 13a, 13b nearest to the S side are provided with a plurality of protuberances l8, 19 in the bearing zone of the rope 14, the rope being pressed against the groove floor 21 by a thrust roller.
