ϊ 750 783

that under difficult operating conditions there is a risk of loosening the threaded ring exists so that the claws can open unintentionally.

Proceeding from this prior art, the invention reads the object of creating a device for quickly connecting and disconnecting pipes of the type mentioned at the outset, which enables simple and quick centering even when the sea is not perfectly calm and almost simultaneous blocking of the: .ohrtnden as well as a quick separation of the same enables, and moreover is designed in a simple manner, to handle and to operate 211.

According to the invention this is achieved in that to eliminate the articulation of the rods to the Claws and the plate ball studs serve and the plate around the axis of the tube / wipe two positions is rotatable. the rods in the one position of the plate, the closed position, essentially in the plane of movement of the claws and in the other position, the separating layer, are inclined to this plane.

In this way it is achieved that the back and forth Rotation of the plate / between two positions takes place, in one of which the rods are essentially located in the planes of movement of the movable claws, while they are in the second end division of the plate are inclined with respect to these planes. If the rods are of such a length that their Ft issue i-t in the idle position when the plate is in the second angular position is located, then the rods are in the first angular position when the plate is rotated compressed, where they store such elastic energy in itself that they close the Claws to block the flanges of the two / 11 connecting pipe ends cause a ge white elastic energy remains stored in the rods, so that a certain holding pressure of the Claws is ensured. If the plate is then rotated a little over the position in which the rods are in the planes of movement of the claws are located, then it is achieved that the claws open again the plate must be rotated in the opposite direction, the one exerted by the spring part of the rods Force prevents a renewed opening without this rotation. The connection of the two pipe ends is open in this way by means of a simple but effective protection against any undesired equipped of the claws, which result in a possible break of the control member of the plate can.

In order to open the claws again, the plate must be rotated in the opposite direction so that it is returned to its second de-angled position. As a result of this reverse rotation, the rods are inclined and thus lengthened, whereby they return to their rest position and cause the claws to open again. This reopening is practically suddenly caused after it is sufficient that the rods cross the dead center, ^lv elk by its location in the planes of movement of the jaws is formed, after which the accumulated in the spring part of the rods energy is released and the G'.dforgane be withdrawn, whereby the rotation of the plate back into its second end position is favored.

The centering of the second pipe end with respect to the first is in this case by two symmetrical ones Caused bracket, which are attached to the flange of the first pipe end and axially from this protrude. With the device according to the invention, the object is achieved, namely the both pipe ends exactly centered and blocked against each other. In particular, uniform blocking is achieved achieved over the entire circumference of the two flanges after arranging several equally long and equally elastic rods at the same mutual distances give the claws a uniform Force is transmitted, which is exerted in a uniform manner through them on the two flanges Pressure affects.

Furthermore, the device according to the invention is easy to operate and, in particular, allows easy and quick opening of the claws, and consequently easy and quick separation of the two peoples. In fact, it is enough. to rotate st'cmäßen embodiment expediently in its second Endwinkellage so that the jaws open rapidly and the second tube end is released from the first: the plate of the erfindun _c.

This quick opening of the claws can be extremely advantageous in the event of a risk of fire, rough seas and the like. Since it is also possible to remotely arrange the control members of the plate, the disconnection of the lines can be carried out by an operator who is remote from the device, so that the dangers to which it is exposed. are reduced to a minimum. In the case of remote control of the device, a closed-loop television system can allow observing the operation of the device and making all the necessary conditions ^; It can only be carried out from a control cabin that is located away from the extinguishing bridge.

An embodiment of the invention is explained in more detail with reference to the drawing, namely show

Fig. 1 and 2 the device according to the invention in Seitenansicnt, with the one representation Claws are shown in the closed and in the other illustration in the open position and Fi g. 3 and 4 the device according to the invention in

Direction of arrows A in FIG. 1 and 2 also with the claws in the closed and open position, the rods for connecting the claws to the plate are shown schematically.

The device shown in Figs. 1 to 4 has a pipe end 51 which at one end with a flange 52 is provided. The claws 53 are hinged to the flange 52 at equal angular intervals and can be pivoted in planes through the axis of the pipe end 5! lead and equal to each other Form dihedral. Each claw 53 is provided with an elastic collar 73 by means of a ball stud 54 is, one end of a rod 55 articulated, the length of which is elastically variable. The others Ends of the rods 55 are hinged to ball studs 56, which are attached to a plate 57 at equal angular intervals are attached and are each provided with an elastic collar 74. The plate 57 is around the end of the pipe 51 rotatable and arranged on the same axis as the same. You can back and forth between two end positions are rotated, these rotations by a cylinder 60 and a displaceable therein Piston 59 comprehensive, arranged in a plane perpendicular to the axis of the pipe end 51 hydraulic fintidiiiin ·! 5ft hfrvorueriifeu be

the can. The free end of the piston 59 connected rod is hinged to a radial projection 61 of the plate 57, while the cylinder 60 is mounted between brackets 62 which are fastened to the pipe end 51. The shifts in the Pistons 59 in cylinder 60 are by alternately introducing pressure medium into the one or the brought about another space of the cylinder and connecting the pressureless space with the drain. The hydraulic circuit is not shown in the drawing because it is easily understandable per se is and includes a hand operated distribution valve.

Each rod 55 consists of a first part 63 and a second part 64, which are connected to one another by means of a Spring coupling 75 are connected, which comprises a sleeve 67 screwed onto the part 64, in the the free end of the part 63 is displaceable, this displacement being counteracted by a spring 65 a spring plate 66 acts, which is arranged around the part 63 and against a screwed onto the part 63 Mother 77 is supported. Furthermore, the parts 63 and 64 are connected to one another by a bolt 76, which is screwed onto part 63 and can be moved in part 64. A collar 71 of the bolt 76 counteracts it an inwardly projecting annular stop 78 of the sleeve 67 for complete extension to prevent the part 63 from the part 64 when the rod 55 is under tension. The length of the not under The compression or tension standing rod 55 is thus through the engagement between the sleeve 67 and the part 64 and adjustable between the bolt 76 and the part 63. The greatest shortening of the rod under pressure can, however, be adjusted by means of the nut 77.

To explain the mode of operation of this device it is initially assumed that the initially in the in the F i g. 2 and 4 are the state shown. The piston 59 is in this state in its front end position in the cylinder 60, the plate 57 is in one of its end positions, the rods 55 are inclined with respect to the planes of movement of the claws 53 and have their greatest length in the tensionless State (springs 65 at rest), the claws 53 are open and there is nothing else on the pipe end 51 Pipe end connected.

Now, when pressure medium is let into the right lying in Figure 4 the end of the cylinder 60, the piston 59 is displaced back in the cylinder and with simultaneous pivoting of the cylinder 60 about the pivot axis in the bearings 62 a rotation of the disk 57 is based in a clockwise direction ( on Fig. 4). As a result of the presence of the ball studs 54 and 56, the position of the rods 55 is changed during this rotation of the plate, which are arranged in the planes of movement of the claws 53, the springs 65 being compressed and storing elastic energy. As soon as the rods 55 are in a position in the mentioned movements

Lo range of the claws 53 are, the stored elastic energy is transferred to the claws 53, which are pivoted about their points of articulation on the flange 52 and thereby press the flange 68 of a second pipe end 70 against the flange 52, which second pipe end 70 is approximated beforehand and by means of symmetrical Bracket 69 was centered, which are welded to the flange 52 and protrude axially therefrom.

For the purpose of closing the claws 53 alone, the plate 57 could also be stopped in that position in which the rods 55 in the Bcwegungscbenen of the claws 53 are located. However, in order to ensure a safe connection even in the event of a fault

tion of the control member of the hydraulic device 58 / u, the plate 57 is still somewhat rotated further so that the rods 55 are inclined somewhat in the opposite direction than before. the End position of the rods 55 with closed Klai.cn 53 '

(which end position is determined by the maximum stroke of the piston 59) is shown in FIGS. 1 and 3 ce /. As can be seen, the bars form 55 with the R.-Jien through the points of articulation on the claws 53 small angles λ, wa- means that for renewed opening of the claws 53 the hydraulic device 58 in opposite Meaning must be actuated, while a break in the DruckmiKelspeisekreiscs by no means unwanted opening of the claws 53 can cause.

To open the claws 53 again and loosen the pipe ends 70 pressure medium must be in the left Space (based on FIG. 3) of the cylinder 60 let in will.

The resulting shift de; KoI-

bens 59 causes plate 57 to rotate counterclockwise (always based on Fig. 3).

As soon as the dead center has been overcome, which is due to the position of the rods 55 in the plane of movement the claws 53 is given, the rods 55 pull the

Claws 53 back and open them, the elastic energy still stored in the rods 55 being the Reverse rotation of the plate 57 into the starting position according to F1 g. 2 and 4 supported. When the device returns to the position shown in these figures,

then the pipe end 70 is no longer held and can be removed.

Since it would be impossible to open the claws 53 again in the event of a malfunction in the pressure medium supply system, a hand-operated pump can be parallel to the

Dining system to be provided to the renewed To enable opening of the claws 53 in any case. Furthermore, since the flanges 52, 68 of the pipe ends 58, 70 to be connected are dependent on the pressure load different strengths of the liquid to be

can sit, it is possible to use the device To provide means for adjusting the axial position of the plate 57 in order to reduce the range of motion of the claws 53 to be adjusted proportionally.
