Definitions

  • the invention relates to a transport device in a tube, in particular a torpedo tube, preferably in a submarine, which enables loading and unloading operations through the tube and is suitable for dispensing mines or containers.
  • US-A-4 640 182 describes a device for a rapid fire gun for grenade launching.
  • This transport device is arranged in the center of a rotatable magazine. It consists of two parallel cylinders in which two parallel pistons, which are connected to each other, are moved. The pistons interact with two parallel chains, which are attached to the cylinders at one point and which move a driver in such a way that when the pistons are pushed out, they travel twice the distance of the pistons and are moved at twice the speed of the pistons.
  • the cross section of this Transport device is approximately equal to the clear cross-section between guides for the grenades, so that it appears to be unsuitable in connection with a torpedo tube, especially since this increases the speed, for. B. for loading operations, but also when dispensing mines and containers is not necessary.
  • the submarines are usually loaded with torpedoes, mines and containers through the upper torpedo tubes, which protrude from the water in a suitably trimmed position of the boat.
  • the objects are guided on guideways.
  • the loading device can therefore be moved essentially over the entire length of the tube.
  • the cramped space of the tube which is shaped as a pressure-resistant cylindrical body and is designed as a torpedo drain tube, must be taken into account.
  • US-A-3 807 274 shows a torpedo tube in which a torpedo or similar body is pushed out by a driver arranged on a chain moved by a hydraulic motor.
  • the path of the driver does not extend over the entire length of the pipe.
  • the chain does not run within the circular cross section of the tube, but in an approximately semicircular bulge, which reduces the compressive strength of the circular cross section or requires additional measures to maintain the strength.
  • This device has in addition to the piston-cylinder unit in the tube two axially displaceable slides and therefore requires a larger tube diameter than is necessary for the delivery of the objects brought in, which leads to increased space and weight of the tube.
  • the document shows a further solution in which a threaded spindle is fixedly mounted on the one hand and can move a spindle housing axially in the tube, which itself runs in a guideway and has a guide for the receiving carriage.
  • this drive device allows only a low extension speed and a mostly undesirable noise can be expected.
  • the object of the invention is therefore to provide a transport device which can be fitted in a tube, in particular in a torpedo tube, which brings about a stroke of almost the length of the tube with perfect guidance of the moving parts, which can be driven hydraulically with sufficient threading and which has a flat design having.
  • a transport device arranged in the tube, which comprises a piston-cylinder unit and a receiving carriage which is driven by a cable when the piston-cylinder unit moves in such a way that a lifting movement of the Piston-cylinder unit results in an approximately double stroke movement of the slide.
  • the piston rod is the piston-cylinder unit arranged parallel to the axis of the tube in the tube near its inner end, whereby the cylinder is profiled on the outside and slidably guided on a slide, while the slide on the profiled as a slideway, to the center of the tube-facing side of the cylinder is movable.
  • the cylinder When the piston rod is fixed, the cylinder can move axially in the tube on a slide rail, and at the same time the slide can move in the same direction on the cylinder.
  • Two pulley pulleys are located on the cylinder. The sled is attached to a run of the cable. The ends of the cable are tensioned and held on fastening devices that are firmly connected to the tube. This ensures that a displacement of the cylinder between its two end positions simultaneously moves the carriage on the cylinder between the two ends of the cylinder.
  • the piston-cylinder unit is preferably designed such that a cylinder is arranged in front of and behind the piston connected to the piston rod in the cylinder.
  • the piston rod is provided with channels for the supply and discharge of the pressure medium into the displacement. The movements of the cylinder are controlled by the differential pressure between the two displacements.
  • the piston rod is mounted on the one hand in a fixed bearing and on the other hand in the piston which is located in the displaceable cylinder.
  • Another bearing for the piston rod may be expedient, which is displaceable on the slide rail and is carried along part of the way by a drag frame when the cylinder is pushed out and which supports the piston rod over approximately half the length when the cylinder is pushed out.
  • the torpedo tube 1 is closed at its inner end 12 by a flap (not shown) and widens to its other end, also not shown.
  • the objects are centered and guided in the tube 1 by guideways 13 (FIG. 2).
  • a piston rod 21 is mounted in a bearing 22 near the inner end 12 and held in place by a screw 39 (FIG. 1).
  • the piston rod 21 is essentially hollow.
  • a tube 23 is inserted into its interior.
  • the bearing 22 has supply lines 24, 25 for a hydraulic pressure medium, one of which leads into the interior of the tube 23, which forms a channel 26, and the other into the space between the tube and the inner circumference of the piston rod 21, where another annular channel 27 is formed leads.
  • the piston 30 is located at the end of the piston rod 21.
  • the cylinder 31 is displaceable on the piston 30.
  • On the outer side of the piston there is a first displacement 28, which is closed to the outside by an insert 36 made of plastic and the cylinder head 32.
  • the channel 26 opens into the displacement 28.
  • a further displacement 29 is located on the inner side of the piston 30 between the cylinder 31 and the outer surface of the piston rod 21 and is sealed towards the inside by a seal on the piston rod 21 which is connected to the cylinder 31 sliding part 38 limited.
  • the displacement 29 is connected to the channel 27 by bores in the piston rod 21.
  • the outer surfaces of the cylinder 31 are profiled on the two sides lying radially to the center of the tube and are designed as guide surfaces in the manner of a dovetail.
  • sliding surfaces 33 the cylinder 31 can be moved on a correspondingly shaped sliding rail 35 made of plastic, which runs on the inner wall of the tube 1.
  • the radial in tube 1 inner side of the cylinder 31 forms a slideway 34 on which the side of the slide 4 formed with corresponding profiles 41 is guided and can slide. (Fig. 2).
  • the cable 5 runs from a fastening device 55, which can be attached to the side of the slide rail 35, via a deflection disk 53, which is also attached to the slide rail 35 by means of a holder 54, to a deflection wheel 51, which is mounted on the cylinder head 32, with a first strand parallel to the axis of the cylinder 31 up to a fastening 42 with which the carriage 4 is fastened to the cable, then via the deflection wheel 52 on the sliding part 38 with an oppositely running strand to a second deflection disk 53 up to one further fastening device 55.
  • the deflection disks 53 are located laterally next to the cylinder 31, approximately in the area of the piston 30.
  • This guidance of the cable pull 5 ensures that the cylinder 4 is moved outwards (to the right in the drawing) by a total of 4 double stroke of the cylinder to the outside (to the right in the drawing), the carriage 4 from a position na he the deflection wheel 52 comes into a position on the deflection wheel 51.
  • the length dimensions of the device parts must be adapted to the necessary stroke paths.
  • the cable 5 provided not only increases the stroke of the carriage 4 but also accelerates its movements.
  • the drag frame of the bearing 37 and structural details such as sealing rings and supports of the tube 23 in the piston rod 21 are not shown to simplify the only schematic drawings. Furthermore, the loading frame to be attached to the carriage 4 with the receiving device for the objects is not shown.
  • the proposed design of the piston-cylinder unit with a displaceable cylinder with a fixed piston and a fixed piston rod not only enables the slide-out part of this unit to be stored correctly, but also simplifies the entire structure of the transport device by creating a sliding guide for the slide directly on the moved cylinder, whereby a very flat design of the transport device is achieved, by means of which the carriage can be moved over almost the entire length of the tube.
