Definitions

  • the invention relates to an unloading device for a cable-drawn carriage of a construction hoist, in particular an inclined hoist, which is guided on at least one guide rail of the construction hoist and is provided with a loading area for transporting building material from the level area upwards, a retaining element arranged at a predetermined position on the guide rail after passage of the ascending carriage automatically arrives in the retention position, such that when the carriage is moving without interrupting the downward movement, the transported goods are automatically removed from the carriage and are received by the retaining element.
  • the advantage of saving time is given, because the unloading of the sled takes place automatically through the stowage flaps, ie the sled can already be loaded again on the floor, while the deposited material is cleared by the unloading team from the stowage flaps.
  • the dimensions of the carriage are such that it can move freely between the flaps during empty travel (from top to bottom).
  • An elevator for construction purposes has become known from German patent specification 3 18 285, in which an emptying frame is provided on the guide rails of the elevator, which can be displaced and locked in any desired preselectable height.
  • the carriage which is rolling on the guide rails of this elevator, is guided into the emptying frame as a result of the train in the traction cable and unloaded there via special angle guides.
  • an emptying frame arranged above the carriage and already fixed is provided on the guide rails of the elevator; however, it was perceived as a disadvantage with this device that special angular guides had to be provided on the slide itself in order to bring the slide into the emptying position on the guide frame.
  • the object of the invention is to find an unloading device for a cable-drawn carriage according to the preamble, in which the carriage does not have to be adapted to the unloading device, or does so only to an extremely insignificant extent, i.e. the slide should be usable with or without an unloading device without a fundamental structural change.
  • pivotable connecting parts on the slide are to be dispensed with.
  • the invention aims to use the train of the load winch rope for the automatic reloading of the goods to be transported from the sled to the unloading device, so that the lifting of the goods to be transported from the sled to the unloading device required during the reloading takes place by means of the load winch rope.
  • the load winch rope thus serves not only to move the carriage, but also to absorb the load weight during the reloading process.
  • the invention solves the stated problem by the teaching of claim 1.
  • the change in height of the receiving surface of the unloading device takes place in that the carriage moves with its loading surface or with the load bearing support supports resting in the area of the receiving surface; since appropriate stops are provided between the carriage (or its loading surface) and the unloading device, the force of the pulling rope is transmitted to the unloading device.
  • the receiving surface of the unloading device is raised as a result of its storage in rockers, so that the load resting on the support supports of the loading surface of the carriage is underpinned and picked up by the unloading device.
  • the rockers carrying the receiving surface are inclined against the ascending carriage until the carriage has passed over the receiving surface with its load.
  • the receiving surface forms approximately a parallelogram joint with the wings and an imaginary line connecting the support points of the wings.
  • the receiving surface of the unloading device which is mounted in rockers, can be lowered to an adjustable dimension; serve for this purpose pivoted limiter characterized in claim 17. The lowering takes place to such an extent that the incoming goods can be moved with certainty over the top of the receiving surface of the unloading device; after the automatic lifting process, the rockers lock automatically in the upright position, so that the now unloaded carriage can return empty.
  • the receiving surface is divided according to claims 9 and 10 into two support plates, between which a free space is formed, which is used to pass the support bearing resting on the loading surface of the carriage.
  • Retaining elements are arranged at the lower (facing the carriage) ends of these support plates; the retaining elements are preferably designed so that they represent flaps locked on one side, which are brought into the inactive position by the arriving goods to be transported (stack of roof tiles) and swivel into the active position behind the rear end of the stack of roof tiles, so that the stack of roof tiles automatically at every inclined position of the elevator is held lying on the support plates while the sledge returns empty. It is not necessary to unlock the retaining elements after the unloading device has been unloaded. The operator only has to release the locking device after the unloading process has ended so that the rockers return to their inclined position while lowering the receiving surface of the unloading device.
  • an embodiment is one Retained element characterized, which consists of a swivel linkage.
  • the swivel linkage is rotatably mounted on the two free ends of the receiving surface.
  • the actuating lever for the swivel linkage is designed as an adjusting screw and is movably mounted on the rocker facing the slide above the axis of rotation connecting the receiving surface to the rocker. This ensures that the tensile force of the sled rope and thus the movement of the rocker is transferred to a sensible lever linkage, by means of which corresponding retaining plates can be pivoted laterally, such that the retaining plates are pivoted laterally inwards into the retaining position when the carriage is retracted into the unloading device .
  • the feature of claim 11 is of particular independent importance.
  • a rail section is provided on which the unloading device is fastened.
  • the height of the surface of the upper flange of this rail section is chosen so that the play of the lower roller of the carriage is essentially exhausted. It can be assumed that a considerable play between the top roller and the bottom roller is essential for the slides for modern inclined lifts, because a large number of guide rail sections are telescoped. If the unloading device were arranged, for example, in the region of the first (upper) guide rail, there would be considerable play between the lower edge of the upper flange of the guide rail and the lower roller.
  • Claims 12-15 relate to advantageous configurations of the fastening of the rail section to the guide rail and the connection between the unloading device and the rail section.
  • an unloading device for an inclined elevator is achieved, with the aid of which material, in particular roof tiles, transported by means of a slide that is used in practice can be reliably deposited on the receiving surface of the unloading device.
  • Fig. 1 denotes an inclined elevator, which consists of individual guide rails 2 and 2 ', the first (upper) guide rail 2' via an elbow 5 is angled.
  • the inclined elevator 1 rests on a chassis 3; the first guide rail 2 'lies against the roof 6 of a building 4. 7 with a sled loaded with roof tiles 13 is designated, which should place the roof tiles in the unloading device 9 with a corresponding upward movement in the direction of arrow 8.
  • FIG. 2 Details of the unloading device 9 can be seen from FIG. 2.
  • the loaded with the roof tiles 13 carriage 7 is supported by upper rollers 27 on the guide rails 2 '.
  • Support supports 25 (FIG. 8) are placed on the loading area 10, on which the roof tiles 13 rest.
  • the unloading device 9 consists essentially of support feet 35, to which rockers 15 are connected, which support plates 23.
  • the front pair of wings 15 is connected by a cross belt 39.
  • the retaining elements designated 11 are arranged at the front end of the support plates 23, which together form the receiving surface 14.
  • the retaining elements are designed as plates which can be pivoted back against spring force and which have a joint which is locked on one side. They pivot freely by contact with the roof tiles 13 in the direction of arrow 42, so that (see also FIG. 9) the slide with its support supports 25 can freely pass the free space 24 between support plates 23.
  • the support plates 23 are in the position shown in FIG.
  • the support plates 23 have the roof tiles from below (Fig. 9) and received (see arrow direction in Fig. 9) so that the carriage can return empty.
  • the retaining elements 11 are now in the retaining position 12 so that the roof tiles cannot slide downwards.
  • the position 12 'pivoted out of the retention position 12' is only reached again when a new roof tile package is retracted after the unloading device has been unloaded.
  • the rail section 26 is fixed by means of spacers 32 and 33 (Fig. 6) relative to the guide rail 2 'at the desired distance and fixed by means of a clamp connection 34 on the guide rail 2'.
  • retaining plates 36 are provided which cover a rung 37 so that they cannot move.
  • the support feet 35 are connected to the rail section 26 by means of a screw connection 41.
  • FIGS. 10-12 A further embodiment of a retaining element 11 'can be seen from FIGS. 10-12, wherein FIG. 10 otherwise corresponds to FIG. 2, while FIGS. 11 and 12 represent detail drawings of FIG. 4.
  • the designated with 11 'retaining element consists of a pivot linkage which is rotatably connected on the outside to the two free ends of the receiving surface 14.
  • the pivot linkage is rotatably mounted on a bearing plate 43 at the rear (upper) end of the receiving surface 14 and has a longer pivot lever 44 which is supported on a front (lower) bearing plate 50 on the receiving surface 14 via two shorter pivot levers 45 and 46.
  • a further pivot lever 47 is connected, which at its free end by means of an adjusting device 49 on the front (lower) rocker 15 ' is pivotally connected in such a way that the articulation point 53 of the pivot lever 47 on the rocker 15 formed into a closed U-frame 'lies above the axis of rotation 52 connecting the receiving surface 14 with the rocker 15'.
