    3 If the torque were to be increased in line with the current self-tensioning moment on the main winches in order to be able to handle an increased maximum load that can and can be transported with the vessel in raga, the ramp's function could be in the above-mentioned buoyancy where it is free to move vertically disappear due to the inertia and losses present in the wire winch of the main winches.
    If the ramp were to be dimensioned to handle an increased load that can be carried and can be transported with the ship in raga, the ramp would be unnecessarily oversized in most cases where the ship is driven or loaded, which means that unnecessarily much steel etc. is involved in the ship's and said ramp construction and that the operating cost increases due to unnecessary weight that must always be carried around with the ship.
    The main object of the present invention is primarily to solve the above-mentioned problems with a safe and functional method and with a hard-working device, respectively. In addition, the aim is to be able to supply already built ships and ramps with the present invention in retrospect as a complement to other safety equipment.
    Said dndamal is achieved by means of a procedure which can mainly be characterized as a drive, that with said main winches the ramp is allowed to support actively, whereby this allows only more load than what the ramp is maximally dimensioned for without standing and with corresponding load distribution as the ramp is dimensioned for, respectively with a device which is mainly characterized in that main winches are connected so that said main winches allow the ramp to be actuated, with a feedback signal arranged there to come from a load-feeding element on the ramp to a control system, in order to enable the ramp to carry heavier load on the same or larger widespread area than what it is structurally dimensioned for, without said active support of the main winch when the load increases along the longitudinal extension of the ramp.
    This is made possible by measuring the current load on the aft ramp (quarter ramp) by mounting load cells on e.g. the buttressing cylinders and feed the current pressure. The pressure signal is reconnected to a control system that regulates the ramp's support through increased torque in the main winches so that the pressure is kept more or less constant when the night reaches its maximum drill value, thus the torque in the ramp's steel structure can be kept constant. With a choice-regulating loop, you can load significantly more, but with less access. in the ramp structure without risking the ramp being knocked over, overloaded or lifted from the quay.
    With the control system, log the current pressure in the buttressing cylinders and the torque (pressure - if you have hydraulic winches) you give to the winches, you can store the maximum loads that are moved between the quay and the ship or vice versa and get useful statistics on when and how often the customer in question, the system uses, how long a loading or unloading procedure takes and whether a problem, alarm or potential overload of the ramp has occurred.
    The invention is described in the following with reference to the accompanying drawings, in which, Fig. 1 shows a perspective view of a stern ramp in a lowered bearing against a quay and with a vehicle running on the ramp, Fig. 2 shows load distribution along schematically shown stern ramp and maneuvering system therefor Fig. 3 shows parts of a known stern ramp, Fig. 4 shows a side view of a ramp in the unloaded loading platform and in a strung stowage ledge, Fig. 5 shows a plan view of the ramp in a folded ledge, Fig. 6 shows a side view of a stern ramp with control system and existing maneuvering system. Fig. 7 shows a stern ramp during maneuvering, and Fig. 8 shows said stern ramp in the closed ldge.
    A method at a ship's ramp 1 and more particularly defined as a quarter ramp, which is actuated by a number of main winches 2, which there are arranged to pivot with the ropes 3 or other towing means the ramp 1 about pivot joints 4 between lowered collar I, in which ldge the ramp 1 extends between the vessel 5 and the quay 6 or other connecting part, respectively suspended storage layer II on board the vessel 5, in which length of the ramp 1 closes an aft cargo opening 7, means that with said main winches 2 the ramp 1 is actively supported, whereby this It is possible to carry an increased maximum load 8 of what the ramp 1 is maximally dimensioned for without standing and with the corresponding load distribution for which the ramp 1 is dimensioned. Fig. 1 shows the ramp in lowered vessel with supported load 8 dArpa. This can be achieved by using a control system 23 to ensure that the ramp 1 is placed proportionally or stepwise against the load 8 which is collected for the occasion on the ramp 1.
    With one or more load cells 10 preferably located on the center span 9 of the ramp 6, the load of the ramp is transmitted via signals 24 to a control system 23 which in turn opposite control signals 25 to a pair of hydraulic proportional valves 22 on hydraulic control system 100, alternatively a frequency converter on electric driven winches.
    With eg pressure sensor on. the ramp 1 can send information about the load condition of the ramp to the control system 23 and the overall maneuvering system 100 which is arranged to support the ramp 1 as required.
    According to the preferred embodiment, the ramp 1 is allowed to be formed by at least pairwise articulated ramp parts 1A, 1B and is allowed to connect at least one load sensing load cell 10 in or in connection with a hydraulic or electric jack 11 acting between said ramp parts 1A, 1B, or in a swing joint 12 between the said ramp parts 1A, 1B.
    Either the load F on the ramp 1 is allowed to be sensed centrally, i.e. along its center line 13 and / or later the load F is sensed along the respective side portions 14, 15 of the ramp. In this case, the load F along the different areas can be separately sensed to have the ramp 1 in order to enable inboard regulation of the ramp position after receiving current information. load F.
    A device 16 which is arranged for carrying out said method at a ship's ramp 1, which is actuated by a number of main winches 2 which are arranged to pivot with the ropes 3 or other towing means the ramp between lowered carriage I, in which the low ramp 1 stretches between the ship 5 and a quay 6 or any other connecting part, respectively suspended storage dock II on board the ship 5 comprises means which enable main winches 2 to be connected so that with said 7 main winches 2 the ramp is actively supported, with a feedback signal 24 which is arranged to come from a load-feeding element on the ramp 1 via a control system 23 to a control system 100, in order to enable the ramp 1 to support heavier loads on the same or larger extended surface than what it is structurally dimensioned for, without said active support of the main winch 2 change the load 8 acres along the length extension of the ramp.
    The ramp 1, which in submerged corridor I extends between the vessel 5 and a quay 6 or other connecting part, respectively in suspended storage floor II closes a cargo opening 7 on board the vessel 5 has main winches 2 connected so that when the cargo 8 increases along the longitudinal extent of the ramp 2 years arranged to be forced to support the ramp 1 actively to enable the said increased load 8 to be possible. Thereby it is arranged to enable the ramp 1 to carry more load 8 than what the ramp 1 is maximally dimensioned for without standing and with the corresponding load distribution as the ramp 1 is dimensioned for.
    A means is arranged on the ramp 1 which, with feedback signal 24, 25 to said main winches 2, regulates its proportional load-increasing active support against the load 8 which is carried on the ramp 1 at the time in question. The said ramp 1, which is formed by at least pairwise pivotally articulated ramp portions 1A, 1B, may have a number of load cells which are preferably bellows at the center span 9 of the ramp to reconnect the ramp At least current load, for example in the inner structure of the ramp, to a control system 23 which in turn faces signals 25 to an overall maneuvering system 100, for subsequent active alignment of the ramp 1 with said main winches 2 so that the ramp 1 is enabled to carry 8 more loads 8 than what the ramp 1 is normally maximally dimensioned to stand only without extra and with the corresponding load distribution that the ramp is 1 year dimensioned for. The said load cells are formed, for example, by pressure sensors which are arranged to sense the load and / or load of the ramp in the pivotally mounted ramp parts bearing shaft 12, and transfer the load result to a control system 23 for the required support of the ramp and an overall maneuvering system 100.
    An example is that in the case of a hydraulically acting jack, which is arranged connected between the ramp parts 1A, 1B of the ramp facing each other, one or more load-sensing load cells are left connected in said jack.
    Means for load sensing there are typically arranged / arranged along the center line 13 of the ramp and / or along the respective side portions 14, 15 of the ramp jointly or separately from each other for separate in-house regulation and / or for in-house separate regulation of the ramp 1.
    Connected to the ramp 1 is a buttressing system 30 which is arranged to regulate the abutment angle of the outer ramp part 20 against a counter-abutting surface 6A of a berth 6 and, if necessary, regulate an effective jack for increasing or decreasing the angle of said ramp outer part. In this case, a load cell 10 connected to said buttressing system 30 is allowed to detect increased load on ramp 1 in order to be able to support ramp 1 at 6kad load F darpa, via the ramp's main winches 2 or other regulating lift means for said ramp 1.
    Fig. 2 shows how heavier load 8 reaches the ramp 1, the pressure increasing in a relevant buttressing jack 11, this side of the ramp 1 being affected by higher torques from its side main winch 2 so that the force 6 increases in the wire tackle 3 so that the ramp 1 can withstand the unknown 9 the load on the ramp 1. With the aid of sensor means 10 separated per side, hydraulic pressure can be sensed in the port and starboard buttressing cylinder 11 and let this be guided towards a constant or stepwise increasing drilling value of the control system 23 where the ramp 1 is supported on each side of the ramp. of the main winch on this side 2. The ramp 1 can be hydraulically actuable, electro-hydraulically or fully electrically actuable. It is important that the ramp 1 does not collapse and rest with its centered bottom part directly against the quay 6 without there being a distance 34 between the quay 6 and the ramp 1. However, that an outer pivotable portion 20 of the ramp 1 rests directly against the quay 6 and its upper surface 6A, and that this ramp portion 20 is affected by the buttress 30 to be pressed against the quay 6 or other surface which the ramp 1 abuts so that the ramp 1 is not lifted from the quay 6. However, said buttressing does not make it possible to solve the problem which the present invention solves by method and device.
    In summary, it can be said that the main object of the invention is to allow the ramp 1 to be actively supported by a procedure by means of the main winches 2 in question. The ramp is thereby made possible to carry more load 8 than the ramp 1 is dimensioned for without city and with corresponding load distribution as ramp 1. is dimensioned for. This is made possible by means of an active control system 23 and said control system is allowed to control the operating system 100 of the ramp 1 to the extent that the ramp 1 is supported proportionally or stepwise against the load 8 collected on the ramp 1. With one or more load cells 10, which are preferably located on the center span 9 of the ramp, the load of the ramp is allowed to be connected to a control system 23 which in turn transmits signals 25 to said maneuvering system 100.
    With pressure sensors on the ramp 1, such information is transmitted in the load load of the ramp to the control system 23 which is arranged to control the operating system 100 of the ramp and to support the ramp 1 as required.
    Preferably, the ramp 1 is formed by at least pairwise articulated ramp parts 1A, 13, and one is allowed to connect one or more load sensing load cells in or adjacent to a hydraulic or electric jack 11 acting between said ramp parts 1A, 13, or in a swing joint 12. between the said ramp parts 1A, 1B, allowing the load F on the ramp 1 to be sensed centrally 13 and / or along the respective side portions 14, 15 of the ramp.
    Finally, it is pointed out that the load F is sensed separately from each other along different areas, the ramp 1 for inboard regulation of the support of the ramp after receiving information on the load F.
    It is further pointed out that a device which injectes itself has its main winches 2 connected in such a way that said main winches 2 allow the ramp to be actively supported, with a reconnected signal 24 from the load sensing means and which is arranged to access the load-bearing elements on the ramp 1 to a control system. 23 and further to a maneuvering system 100, to enable the ramp 1 to support heavier loads 8 on the same widespread surface than what it is structurally dimensioned for, without said active replacement of the main winch 2 when the load 8 increases along the longitudinal extent of the ramp. Arranged on the ramp 1 is a load sensing means which, with a signal 24 connected to said main winches 2 via a control system 23, is arranged to regulate its proportional load-increasing support against the load 8 which is collected on the ramp 1 in the event in question.
    At the ramp 1, which is formed by ramp portions 1A, 1B pivotally hinged to each other, a number of load cells are located at the center span 9 of the ramp to reconnect the ramp at least current load, for example in the inner structure of the ramp for subsequent alignment of the ramp 1 with said main winch 2. The said load cells can be formed by a number of pressure sensors which are arranged to sense the load and / or load of the ramp in the pivotally mounted ramp parts bearing shaft 12, and via signals 24 Transfer the load result to a control system 23 for the required active support of the ramp and via signals 25 to a control system 100, for subsequent control by means of the main winches 2.
    A hydraulically acting jack can be arranged connected between the ramp parts 1A, 1B facing each other, wherein one or more load-bearing load cells dr are connected in said jack.
    Other means for load sensing may be arranged / arranged along the center line 13 of the ramp and / or along the respective side portions 14, 15 of the ramp jointly or separately from each other for separate inboard control and / or for inboard separate control of the ramp 1.
    Connected to the ramp 1 is a buttressing system which is arranged to regulate the abutment angle of the outer ramp part 20 towards a counter 6 abutable surface 6A and, if necessary, to regulate an effective jack for increasing or decreasing the angle of said ramp outer part. In this case, one or more load cells can be connected to said buttressing system in order to detect increased load on ramp 1 and to be able to support ramp 1 at 12 increased load F darpa via the ramp's main winches 2 or other regulating lift means for said ramp 1.
    A control system 23 is arranged connected to the ramp 1 for receiving incoming signals 24 from a number of load-supplying elements on the ramp 1 and for outgoing signals 25 being arranged to be delivered to a said control system 100, which comprises a pump 21, a number of hydraulic proportional valves 22 and hydraulic lines or tubes 26 are subsequently regulated by said main winches 2 and ropes 3.
    The nature and function of the invention should have been understood from the foregoing and from what is shown in the drawings.
    The invention is of course not limited to the embodiments described above and shown in the accompanying drawings. Modifications are possible, especially when it comes to the nature of the various parts, or by using equivalent technology, without departing from the scope of the invention, as defined in the claims. 13

    1. In addition, the weight of the vessel increases, which increases fuel consumption. For this type of ship ramp, there are known systems such as buttressing and self-tensioning, the main system of the latter system is to ensure that the main winch wires are stretched so that they in turn do not hang down over the ramp and risk getting caught in vehicles loaded. majliggOra a certain reduction of the quay pressure that the ramp gives when it rests against the quay in its extended kOrldge. Self-tensioning means that you set a certain torque on the winches and stretch the wires required during the entire loading and unloading sequence. Another edge system at ramps for sensing and regulating the ramp's and functional corollary and condition is the so-called buttressing. However, this known system is only arranged and intended to detect the distance to the quay or other fixed object and to be able to regulate the abutable part of the outer part of the ramp against the intended abutable horizontal berth surface against which the outer part of the ramp abuts. The well-known buttressing and self-tensioning systems are not intended to increase the barking shape of the ramp, e.g. heavy vehicles or other heavy loads are driven on the ramp between ship and quay or vice versa due to the fact that the ramp must be free to move vertically as the depth of the boat changes during loading and that the berth height changes due to the tide difference. 3 If the torque were to be increased in line with the current self-tensioning moment on the main winches in order to be able to handle an increased maximum load that can and can be transported with the vessel in raga, the ramp's function could be in the above-mentioned buoyancy where it is free to move vertically disappear due to the inertia and losses present in the wire winch of the main winches.
