The invention relates to a reversible loading bridge for ships with an inner bridge part articulated to pivot about a horizontal axis, and an outer bridge part articulated to the inner bridge part so that when the loading bridge is turned upright against the underside of the inner bridge part by means of rope hoists and reversible, and rope pulleys by means of which the outer bridge part can be pivoted with respect to the inner bridge part, the ropes of the outer bridge part being guided by rope rollers arranged in connection with the cantilever arms, which cantilever arms are .

In the loading bridge known from DE-0S 20 46900, a rope hoist is used at its free end to turn the outer bridge part with a flap at its free end, which is guided by a winch fitted to the inner bridge part. Such a winch is a relatively expensive structural element. In addition, when raising and lowering the loading bridge, the operation of this winch must be adapted to the operation of the main winch, which allows the internal loading bridge to be turned. Therefore, additional monitoring connections are also required.

59760 2

The object of the invention is to provide a loading bridge of the type described, in which it is possible to operate an external bridge part without an additional winch.

According to the invention, this object is solved in that the ship-side ends of the guide ropes controlling the relative rotation of the outer bridge are guided in the area of the ship's side suspension ropes via fastening devices in connection with the ship's hull and fixed in this area so that the outer bridge turns alone. .

Some suitable embodiments of the solution according to the invention are set out in the subclaims.

The invention will be explained in detail on the basis of a drawing illustrating some embodiments thereof.

Figure 1 shows a perspective view of the loading bridge in its effective folded down position.

Fig. 2 shows the device according to Fig. 1 seen from the side of the loading bridge and with the loading bridge in its upright rest position and folded down to some intermediate positions.

Figure 3 shows on an enlarged scale a part of the loading bridge located in the region of the connecting joint of the inner and outer bridge part.

Figures U ... 7 show different embodiments of the ship-side suspension of the control ropes of the outer bridge section.

Fig. 8 shows a representation similar to Fig. 1 of a modified embodiment of the loading bridge.

Fig. 9 shows a side view of the movements of the bridge parts when the loading bridge shown in Fig. 8 is turned up and down.

Figure 1 schematically shows the stern of ship 1. The ship is at berth 2 so that its longitudinal axis 3 is parallel to berth 3 59760. The loading bridge 4 is arranged at the stern of the ship so as to form an angle with the longitudinal axis of the ship. The loading bridge 4 has an inner bridge part 4a and an outer bridge part 4b. The two bridge parts 4a and 4b are connected to each other by means of a joint 5 so that the outer bridge part 4b can be turned against the underside of the inner bridge part 4a so that in the upright rest position shown in Fig. 2 these two bridge parts are parallel to each other.

The inner bridge part 4a is connected to the ship 1 by means of a horizontal joint 6 in the region of the stern gate 30 leading to the intermediate deck 29. The overflow flaps 28 allow for a smooth transition.

A flap 4c is fitted to the outer end of the outer bridge part 4b by means of a hinge connection 5a, which ensures a wide-surface pressing of the outer bridge part 4b into the ground. The transition of the outer end of the flap 4c is ensured by the transition flaps 27.

The inner bridge part 4a has side beams 7, the outer ends of which are fitted with multi-part rope hoists 8. Their guide ropes are guided by the inner bridge section through rope rollers 9 and at the upper end by a roller 12 attached to a post 13 on the ship's upper deck. located in front of the column 13 on the top deck 11.

Attached to the outer bridge part 4b is a cantilever arm 23 extending past the articulation 5. A guide rope 15 is used to guide the outer bridge part 4b, i.e. to fold out the outer bridge part when the inner bridge part is folded down.

This guide rope is attached at one end to the attachment point 14a of the holder. This holder is attached to the side member 7 of the inner bridge section, and the rope pulley 14 is mounted on this holder. At the end of the cantilever arm 23, rope rollers 19 are arranged. The rope rollers 14 and 19 form a hoist between the cantilever arm and the inner bridge part 4a.

The other end of the guide rope 15 is fastened to the upper end of the column 13 by a fastening device 17, 18 and is guided here through the rope rollers 16 to the fastening point 18. In the region of this fastening point 18 there is a rope S9760 μ lock 17, so the length of the rope 15 is thus constant.

In the rest position shown in Fig. 2, the inner bridge part and the flat outer part turned against it are fixed to the hull of the ship. Almost the entire length of the guide rope 15 is stored in the hoist between the rollers 1i + and 19.

To fold down the loading bridge, its attachment is first removed. The inner bridge portion is then initialized by a push cylinder 24. The inner part of the bridge then turns around the joint 6 under the influence of its own weight, whereby the movement is controlled by winches 10, from which the guide ropes of the rope hoists are wound.

During the pivoting movement of the inner bridge part 4a, the outer bridge part 4b turns downwards under the control of the guide ropes 15, whereby the number of ropes corresponding to each turning angle of the inner bridge part is pulled from the rope hoists between the rollers 14 and 19. The lengths of the ropes are then dimensioned in such a way that, for example, after a turn of 45 °, which is shown in Fig. 2 as an intermediate position, there is already a wide deflection of the outer bridge part from the inner bridge part - position C2 ·

In position Cg, the external bridge part 4b rests on platform 2. This position Cg can be, for example, the highest permitted position. When the ship 1 is located higher or when the platform 2 is located deeper, a position C 1 may finally occur, in which the ropes 15 have become almost completely pulled from the rope hoists between the rollers 14 and 19.

As can be easily seen, the outer bridge part 4b, at least between the positions Cg and C?

Since the ropes in the working area of the lowered loading bridge 15 are inactive, it may happen that these ropes hang down untensioned. To avoid such down-hanging, the fastening devices 31, 34 of the ship-side ends of the ropes 15 have; 36, 37; 37.38; 39 self-tensioning devices 31; 36; 38; 39 and cooperating with these 5 59760 on-board stops 34 or anchor points 37, as shown in detail in Figures 4-7.

In the embodiment according to Fig. 4, a weight is attached to the ship-side end of the rope 15 as a tensioning device 31, which on the rear side of the post 13 can move on rollers 32 along an inclined guide track 33 with a fixed stop 34 at its upper end. The rope 15 is then guided around the post 16

When the loading bridge is folded down, the weight remains pressed against the stop 34 due to the rope tension. The ship-side fastening thus remains fixed until the rope 15 loosens.

The weight can then roll downwards and thus keep the rope 15 taut. When the loading bridge is turned up, the weight again moves towards the stop 34 as soon as the outer bridge part 4b loads this rope 15.

In the embodiment shown in Fig. 5, the ship-side end of the rope 15 is again turned downwards through the rope rollers 16a and led to the attachment point 37 as a compressed air-operated spring to keep the rope 15 tightened.

In the embodiment shown in Fig. 6, the rope 15 is also guided through a pivot roller 35 to an attachment point 37. Here, the pivot roller is attached to the end of the piston rod, which is loaded by the spring device formed by the tensioning device 38, which keeps the piston rod and The spring device can then be a mechanical coil or disc spring device, but it is also possible to use a spring acting under the influence of gas pressure, in which, for example, nitrogen is used as the pressure medium.

Finally, in the embodiment shown in Fig. 7, a winch generating a constant traction force is arranged in connection with the column 13 as a fastening and tightening device 39, to which the end of the rope 15 is fastened and which keeps the rope under constant tension.

6 59760

As shown in Fig. 3, counterweights 40 can be fitted to the ends of the cantilever arms 23, which act as a counterweight to the outer bridge part 4b and remove the load of the rope 15.

The embodiment shown in Fig. 8 substantially corresponds to that shown in Fig. 1, but in contrast, the cantilever arms 22 are attached to the inner bridge portion 4a so as to extend over the joint 5 in the direction of the outer bridge portion 4b. The series of movements shown in Fig. 9 from an upright rest position through a downward position B1 and various unnumbered intermediate positions to a position Bg, where the outer bridge part first presses to the ground and finally the loading bridge movement in the working area between positions Bg and B1 +, corresponds essentially to the above.

Fig. 9 is a view similar to Figs. 8 illustrates schematically and in detail the operation of the tightening device according to 8. The weight acting as the clamping device 31 is shown here as freely suspended, and the stop 34 is located at the upper end of the column 13. The position is the weight position. The distance between the weight in the position A 1 and the stop 34 is chosen so that the weight reaches the stop when the loading bridge reaches the position B2. Thus, between positions B 1 and B 1, the rope 15 is inactive. As the downward movement continues from position B2, the weight remains depressed in the stop 34. After the outer bridge part has depressed into the platform 2, the stress of the rope 15 first decreases much, as a result of which the weight falls to the position Ag. As the movement continues from the position Bg towards the position B 1, in the embodiment described here the weight rises again to the position A 1, but it does not reach the response 34.
