Definitions
- the invention relates to an unloading device for the cable-drawn carriage of an inclined elevator, which is guided on guide rails of the inclined elevator and has a loading area for transporting building material, the unloading device, which is stationary in the upper region of the inclined elevator, on the guide rails of the same, being able to be lifted by the cable-pulled, ascending carriage and in the raised position by means of a locking device which is automatically locked against lowering for automatically transferring the building material from the loading surface of the carriage to the receiving surface of the unloading device and means for retaining the building material on the receiving surface of the unloading device are provided on the unloading device.
- a aforementioned device has become known from British patent application 21 36 772.
- the receiving surface of the known unloading device can be raised at its front (lower) end via a lever which can be pivoted by the sliding carriage which, in the lowered position of the receiving surface, is arranged in a stowed position next to the guide rails and is erected by the carriage during the retraction of the carriage .
- the aforementioned lever not only lifts the front (lower) end of the receiving surface, but at the same time pushes the roof tile package onto the receiving surface by grasping the front (lower) end of the roof tile package.
- the rear (upper) end of the receiving surface cannot be rotated in height about an articulation point which is formed by a rod sliding in a hole guide.
- the component lifting the receiving surface and the component securing the tile package in the unloading position form a single component, the front edges of the roof tiles are subjected to pressure, so that damage occurs here.
- the lifting of the receiving surface of the unloading device on one side only has a negative effect.
- a device has become known in which an auxiliary scaffold is arranged between a building and the mast of a construction hoist, which has storage flaps at the level of the individual floors, which are driven over by the carriage guided on the mast in such a way that by the The flaps automatically move into an effective position so that the slide, when driving downward, without interrupting the downward movement, places the material transported on the slide on the flaps can.
- the dimensions of the carriage are such that it can move freely between the flaps during empty travel (from top to bottom).
- a device for feeding tool carriers in and out of assembly and processing stations has become known from German published patent application 31 01 659, which is concerned with the formation of a transfer station for the aforementioned tool carriers.
- the aforementioned device sets its own Energy supply of the transfer station (actuation of the swing arm by hydraulic cylinders or the like) ahead; the device is also designed in such a way that the wings of the second carriage can either lift off the workpiece being transported or let it pass through the carriage.
- the object of the invention is to optimize the process of transferring the building material, in particular roof tiles, from the loading area of the carriage to the receiving area of the unloading device.
- damage to the end edges of the roof tiles is to be avoided when the roof tile package is being transferred, and the tiles are to be set down to the exact height, while at the same time the roof tile package is to be retained safely and in a gentle manner on the receiving surface against slipping.
- 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 lying in the loading surface into the region of the receiving surface; since between the carriage (or its loading area) and the Appropriate stops are provided for the unloading device, the force of the traction cable is transmitted to the unloading device.
- the receiving surface of the unloading device is raised as a result of its bearing in rockers, so that the load resting on the support supports of the loading area of the carriage is picked up and picked up by the unloading device.
- the entire unloading device is adjustably supported by means of the short, height-adjustable rail section on the guide rails of the inclined elevator so that an adaptation to the size of the guide rails used in each case, taking into account the play between the upper and lower rollers, gives a precisely fixable distance between the receiving surface and the guide rails of the inclined elevator .
- the receiving surface of the unloading device which is mounted in rockers, can be lowered to an adjustable dimension; for this purpose serve the pivot limiter characterized in claim 7.
- 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 wings lock automatically in the upright position, so that the now unloaded sledge can return empty.
- the receiving surface is divided according to claim 2 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 ends (facing the carriage) 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 sled moves back 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 of a retaining element is 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 Carriage ropes 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 moved into the unloading device.
- the characteristic feature d of claim 1 and the features of subclaims 3 and 4 are of particular importance insofar as a rail section is provided according to which the unloading device is attached.
- 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 upper and lower 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. If the inclined elevator is relatively steep, the carriage can tip over this play, so that?
- the claims 5-6 relate to advantageous embodiments 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 used in practice can be deposited reliably and gently on the receiving surface of an 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, which is to 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'.
