Definitions

  • the invention relates to a device which is suitable for bulging cuboid steel containers used for the transport of goods, which have a floor, a ceiling and four side walls.
  • DE-B 1552975 describes a device used for restoring motor vehicle bodies and chassis.
  • This device has a support held by a support and three arms arranged in the form of a T in a vertical plane; a working cylinder attached to the carrier can optionally be linked to one of the three arms.
  • GB-A 1 201 435 also describes a device by means of which deformations on pipes of circular cross section can be compensated for.
  • the device which can be moved within the pipeline has a plurality of radially arranged hydraulic tappets which interact with shaped parts which are adapted to the contour of the pipeline inner wall.
  • the device has a frame designated as a whole by 1, the base frame of which has three frame legs 2, 3, 4 and an intermediate support 5.
  • Four wheels 6, 7, 8, 9 are loosely rotatably mounted on the frame legs 2, 3 and 4.
  • a tubular structure 10 attached to the base frame serves on the one hand as a boundary, and on the other hand for pushing when moving the frame.
  • a support column 11 protrudes upward from the intermediate carrier 5 and carries a free-lift hydraulic unit, which is not visible here and is designated 62/63 in FIG. 13.
  • This hydraulic unit is anchored with its lower part on the support column 11 and is used to raise and lower a sled carrier 12 on which a sled 14 is slidably guided.
  • the carriage 14 (cf. also FIG. 13) is connected via chains 60 to a movable cylinder 62 of the hydraulic unit. During the lifting movement, the carriage 14 is first raised by the chains 66 and then the carriage carrier 12 slides into the uppermost position with the carriage and the pressure beam 13 attached to the carriage.
  • the carriage support 12 is thus also slid vertically on the circumference of the support column 11.
  • the pressure beam 13 is rotatably supported in the central region on the slide 14 and coupled to a hydraulic swivel unit 51 (FIGS. 11 and 12).
  • Two pressure arms 13a, 13b are slidably mounted on the circumference of the pressure beam 13.
  • Each of these pressure arms 13a, 13b houses a double-acting hydraulic cylinder; each of these hydraulic cylinders is fastened to the central part of the pressure beam 13 and its piston rod is connected to the pressure arm 13a, 13b in question in such a way that the two pressure arms can be extended from the center to both sides if necessary.
  • each swivel arm 15-18 it carries a toothed segment which meshes with a toothed rack arranged in the respective frame leg 2, 4, whereby each toothed segment 45,46 (FIG. 7) with a toothed rack 42 arranged in the respective frame leg 2, 4 7 and 8) combs, one tooth segment of each associated pair of rollers 15, 16 and 17, 18 below, the other above the rack 42 is arranged.
  • a control system 24 is also arranged on the support column 11, and a lamp 25 for illuminating the workplace is arranged on the slide support 12.
  • a horizontal support profile 26 is detachably attached to the pressure arm 13a, while the opposite pressure arm 13b carries a directional profile 27 which is adapted to the contours of the container wall. If the container side wall now has a bulge protruding inwards, the device is pushed to the relevant point, the pressure beam 13 is brought to the desired height by a drive (to be described) (FIG. 13) and the two pressure arms 13a, 13b are extended laterally, until the support profile 26 rests on a side wall and the directional profile 27 engages in the dented groove of the opposite wall. The damage can then be corrected by applying an appropriate hydraulic pressure to the two pressure arms 13a, 13b.
  • the frame 1 is first pushed as far as possible to the edge of the container floor, whereupon the two pairs of swivel arms 19, 20 and 21, 22 are pivoted as far in the direction of the arrow (FIG. 2) until the wheels 6 to 9 are above the level of the container floor 28.
  • the rollers 15, 16 rest on the container floor 28, the rollers 17, 18 on the workshop floor 29.
  • the device can be easily pushed into the container and lowered onto the floor 28, whereupon the swivel arms automatically return to their rest position according to FIG. 1 take in.
  • the actuation of the swivel arm pairs 19, 20 and 21, 22 can, for example, take place according to an embodiment which is shown schematically in FIGS. 7 and 8, only one swivel arm 19 and 21 being shown here for the sake of simplicity.
  • the frame 1 is still on the workshop floor 29 and is now to be lifted onto the container floor 28, which is a distance h above the workshop floor 29.
  • This rack is provided in the region of the lower ends of the two swivel arms 19 and 21, each with a toothed end section 43 or 44, the toothing of one end section 43 pointing downward, whereas the toothing of the opposite end section 44 is directed upward.
  • the serrations of the two end sections 43 and 44 are in constant engagement with the tooth segments 45 and 46 of the two swivel arms 19 and 21.
  • the rack is slidably mounted in a known manner, for example by slide bearings 47 and 48.
  • the swivel arm 19 is considerably smaller than the opposite swivel arm 21.
  • the rack 42 has an offset 46, so that the toothed segment 45 comes to lie below the rack end section 43.
  • the entire facility can also be inserted into the container by hand.
  • the pressure beam 13 is in its vertical position, in which damage to the container ceiling can be compensated for.
  • the support profile 26 opposite the directional profile 27 is supported on the container floor.
  • FIG. 4 A further application of the device is shown in FIG. 4.
  • An insert 30, 31, 32 is inserted in corresponding recesses in the two pressure arms 13a, 13b and in the central region of the pressure beam 13.
  • the device is located below the container, which was lifted onto an appropriate supporting structure, for example by an indoor crane.
  • an appropriate supporting structure for example by an indoor crane.
  • Fig. 5 shows the position of the pressure beam 13 when straightening a transverse to the side walls end wall.
  • a directional profile 27, 27a is arranged at the ends of both pressure arms 13a, 13b and both directional profiles are pressed into the corresponding grooves of the two container side walls 33, 34 in order to absorb the reaction forces that occur.
  • FIGS. 9 and 10 A preferred embodiment variant of such an arrangement is shown in FIGS. 9 and 10, the reference numbers already introduced being retained.
  • the figures show the pressure beam 13, on which, as already described, the two pressure arms 13a and 13b are slidably mounted and their inner ends are connected to the hydraulic cylinders mentioned.
  • the pressure bar 13 is formed in this embodiment as a hollow box profile of practically square cross-section and carries in its central region a loose sliding piece 52 on the same, which engages around the pressure bar 13 practically on all sides and can be displaced thereon in the direction of the double arrow 53.
  • this sliding piece 52 On the front side, this sliding piece 52 carries a support rail 54 designed as an upright U-profile, which is used to hang up the mobile hydraulic cylinder 23.
  • the latter carries an L-shaped plate 55 at one end, on the upper web of which two loosely rotatably mounted rollers 56 are arranged.
  • These rollers 56 are matched in shape and size to the mounting rail 54 in such a way that they can be pushed into it, the plate 55 resting with its inner surface on a pin 57 of the sliding piece 52, and the mobile hydraulic cylinder 23 is thus securely supported.
  • the two pressure arms 13a and 13b of the pressure beam 13 are also provided with support rails 58 and 59, in which the mobile hydraulic cylinder 23 is inserted in the manner described and thanks to the two rollers 56 to one as desired can move any position.
  • the straightening profiles can be loosely attached to the pressure arms 13a, 13b and to the hydraulic cylinder 23 and are secured in this operating position by a spring-loaded locking device.
  • a spring-loaded locking device In view of the numerous profile dimensions of the container walls, it is advisable to hold a straightening profile magazine so that the required straightening profile is at hand as needed.
  • the power transmission from the free-stroke cylinder actuating the support beam to a trolley carrying the support beam and slidably mounted on the slide carrier is preferably carried out via a transmission gear, which can be designed, for example, in the form of at least one chain guided by gear wheels.
  • FIG. 13 An embodiment of such a power transmission is shown schematically in FIG. 13.
  • the carriage 14 is connected to a hydraulically loadable outer cylinder 62 via two chains 60, only one of which is shown in FIG. 13, and a countershaft 61 consisting of chain wheels.
  • This outer cylinder 62 is vertically displaceably mounted on the circumference of an inner cylinder 63, a piston 64 being arranged in the inner cylinder 63.
  • the outer cylinder 62 If the outer cylinder 62 is in the lower position shown in dash-dotted lines, it can be moved upward by introducing hydraulic medium into the space 62a, whereby the two countershaft wheels, which are firmly connected to the upper edge of the outer cylinder 62 via a carrier 66, entrains, so that the countershaft wheels 65 also move from their lower to their upper position and the bar 13 is accordingly lowered into its fully extended position. To raise the pressure bar 13, the space designated 62b in FIG. 13 is accordingly acted upon by pressure medium.
  • the inner cylinder 63 is opposite the stationary, i.e. stationary anchored piston 64 movable and sealed with respect to its outer surface by an annular bead 63a. In its central region, this inner cylinder 63 has a further annular bead 63b, which is used on the one hand for guiding on the inner surface of the outer cylinder 62 and on the other hand for dividing the two pressure spaces 62a and 62b.
  • the pressure beam 13 can be rotated about a horizontal axis, so that it can be brought from its horizontal to its vertical working position.
  • a diagonal working position is also possible.
  • An embodiment of a drive that can be used for this is shown in FIGS. 11 and 12.
  • a permanently installed hydraulic cylinder 51 engages on the side flange of a U-profile 70, designated 70a, the piston 51a of which is articulated to the flange 70a via a joint 68; the housing 51 b forming the cylinder is connected to the pressure beam 13 via a lever 71 and a joint 72.
  • the hydraulic cylinder 51 When the hydraulic cylinder 51 is actuated, its cylindrical housing 51 b is thus moved in the direction of the arrow according to FIG. 12, the pressure bar 13 being pivoted about a horizontal axis.
  • the mobile hydraulic cylinder 23 has a lateral extension 37 (FIG. 6) on its housing. In the working position of the hydraulic cylinder 23, it is attached to the damaged U-profile U in such a way that the support plate 38 connected to the piston rod of the hydraulic cylinder rests on the upper flange 39 and the shoulder 37 on the lower flange 40 of the U-profile.
  • a bulge labeled B can be compensated, for example.
  • the pressure beam 13, which is rotatably attached to the trolley 14, can practically be lowered to the level of the container floor and, on the other hand, raised to the container ceiling.
  • this is achieved by a two-stage lifting device: on the one hand, the carriage 14 can be moved up and down on the carriage support 12, on the other hand, the carriage support 12 can be moved vertically with the carriage 14 on the support column 11.
  • another stroke drive or an electric drive could also be used.
