Definitions

  • the invention relates to a construction hoist, in particular a scaffold hoist with a base frame which can be supported on the floor, a multi-part, vertical guide mast which can be connected to it, a lifting carriage which can be moved thereon and which has hooking means on its front side facing away from the guide mast, and with a first conveying basket which can be hooked onto this. as well as with a second conveyor basket.
  • the invention is therefore based on the object of providing a construction hoist, in particular a scaffold hoist of the type mentioned at the outset, which is simpler in construction and thus less expensive to manufacture.
  • the two conveyor baskets can be hung alternately on the same lifting carriage and for this purpose a horizontal support arm is mounted on each side of the guide mast and at a distance from it for each conveyor basket so that it can pivot freely about a vertical pivot axis by about 90 ° End in a first swivel position in front of the lifting carriage and in the second swivel position to the side of it, that a vertical support is fastened to each support arm in the vicinity of its swivel axis, which is arranged in the first swivel position to the side of the lifting carriage, and that on the side facing the lifting carriage
  • the invention is therefore based on the idea of placing one of the conveyor baskets near the floor for loading on a special receiving means, namely the horizontally pivotable support arm, depending on the lifting carriage and parking it laterally by pivoting the support arm, and the previously loaded second conveyor basket by means of the to pivot it assigned to the second support arm to the lifting carriage, to hang on it and to move upwards.
  • a special receiving means namely the horizontally pivotable support arm, depending on the lifting carriage and parking it laterally by pivoting the support arm, and the previously loaded second conveyor basket by means of the to pivot it assigned to the second support arm to the lifting carriage, to hang on it and to move upwards.
  • the second conveyor basket loaded with scaffolding parts for example, moves upwards and is unloaded by several scaffolding workers at the top
  • the first suspended conveyor basket can be loaded with scaffolding parts below by a single scaffolding worker.
  • the unloaded second conveyor basket is back on the ground, it is unhooked and put aside, after which the loaded first conveyor basket can be hung on the lifting carriage again.
  • the two support arms which can be swiveled out laterally, serve as receptacles for each of the conveyor baskets.
  • the support bracket arranged on the support arm and the centering piece arranged on the respective conveyor cage ensure that the conveyor cage can also be pivoted back in position in front of the lifting carriage in such a way that the suspension means provided on the lifting carriage and on the conveyor cage engage when lifting the lifting carriage. Since the new construction elevator only has a conveyor carriage, there is no rack, a second lifting carriage, a drive motor with gear and pinion and a second power supply with control compared to the previously known construction elevator. This makes the new construction elevator easier to build and cheaper to manufacture.
  • an inclined building elevator which is used to transport building materials such as roof tiles, roof tiles or roof tiles.
  • This inclined construction elevator has a lifting carriage that can be moved vertically on rails, which carries a horizontal C-rail that is open to the front at its upper edge.
  • a stacking frame in the form of a brick distributor known per se has, among other things, two rollers on its rear side, which can be inserted from the side into the C-rail of the lifting carriage. In this way, a brick distributor on the ground can be loaded independently of the provision of the lifting carriage, then connected to the lifting carriage and raised with it.
  • the tile distributor On the roof there is a swivel frame which can be fixed on the roof battens next to the lifting slide and on which the tile distributor can be moved by the lifting slide. By lowering a part of the swivel frame, the tile distributor can be placed on the roof battens and moved on them.
  • the loaded brick distributor it is not specified how the loaded brick distributor can be connected to the lifting carriage in a simple manner near the ground.
  • another brick distributor instead of one Stacking frame or conveyor basket with heavy and bulky scaffolding parts would be connected to the lifting carriage, it is difficult to align the stacking frame with respect to the C-rail so that the rollers are exactly aligned with the C-rail of the lifting carriage.
  • an adapter is provided between the brick distributor and the lifting slide.
  • This adapter has at its lower end two hooks with which it can be hung on a cross tube of the lifting carriage.
  • the lifting carriage In the upper area, the lifting carriage has a bolt lock with which the adapter can be locked on the lifting carriage.
  • the adapter At its upper end, the adapter in turn carries a C-rail, into which the brick distributor with its rollers can be inserted.
  • the brick distributor itself is similar to a so-called hand truck, equipped with two wheels and two handles. The bolt lock can be released close to the ground, thus releasing the adapter from the lifting slide together with the brick distributor.
  • the brick distributor, together with the adapter, can then be moved laterally for loading by means of the wheels, similar to a plunger cart.
  • the adapter since the adapter is connected to the brick distributor during loading, no other loaded brick distributor can now be attached to the lifting carriage, unless a separate adapter is provided for each brick distributor, which would however be correspondingly expensive.
  • This known inclined elevator would not be suitable for transporting heavy and bulky loads, in particular scaffolding parts, because a larger number of scaffolding parts because of their bulkiness and their weight could not be handled like a hand truck.
  • a vertical guide mast 2 can be fastened to a base frame 1 which can be supported on the ground and which can be plugged together from individual parts up to the desired delivery height.
  • a lifting slide 3 is mounted on the guide mast 2 so that it can move in height.
  • an electric motor not shown, can be provided on the lifting carriage and drives a pinion via a gear. This engages in one on the guide mast provided, also not shown rack.
  • the power supply and control of the drive motor takes place via a trailing cable.
  • the lifting carriage can also be driven by means of a cable winch.
  • the lifting carriage 3 has, on its front facing away from the guide mast 2, hanging means on which the two conveyor baskets 4 and 4 'can be alternately hung.
  • two hooks 5, which are arranged at a horizontal distance from one another and are open at the top and act on a longitudinal bar 4a of the respective conveyor cage 4, 4 ', can be provided as the hanging means, as can be seen in particular from FIG.
  • the lifting slide 3 has two laterally protruding rollers 6 as hooking means, which can be hooked into hooks 7 of the conveyor basket which are open at the bottom. These hooks 7 are welded to vertical struts 4b of the conveyor cage 4 or 4 '.
  • a horizontal support arm 8, 8 ' is pivotally mounted about a vertical pivot axis 9, 9' by about 90 °.
  • the free end 8a or 8'a is located in front of the lifting slide 3.
  • the left support arm 8 is shown in its first swivel position, while the right swivel arm 8 'is shown in its second swivel position. In this second swivel position, the free end 8a or 8'a is located to the side of the lifting carriage 3.
  • a vertical support bracket 10, 10 ' is also attached to each support arm 8, 8'.
  • each conveyor cage 4, 4 'facing the lifting carriage a holding bracket 11, 11' is fastened, which is connected to the holding support 10, 10 'of the associated support arm 8, 8 'cooperates.
  • the holding brackets 11, 11 ' are designed in such a way that the upper end of the holding support 10, 10' can be inserted into the associated holding bracket 11, 11 'when the lifting carriage 3 moves vertically.
  • each of the support arms 8, 8 ' is assigned a spring 13, 13', which in the exemplary embodiment shown is designed as a gas pressure spring.
  • One end 13a of each of these gas pressure springs 13, 13 ' is articulated on the associated support arm 8, 8'.
  • the other end 13 b is arranged on the base frame 1 at a distance from the pivot axis 9, 9 'so that when the support arm 8' is pivoted in the middle of its pivoting movement, the spring 13, 13 'reaches a dead center position.
  • the greatest spring tension occurs in this dead center position, but the spring 13, 13 'does not exert any moment on the associated support arm 8, 8', since in this dead center position the line of action of the spring 13, 13 'runs through the pivot axis 9, 9' .
  • a double-armed, spring-loaded locking bolt 15 is pivotably mounted on the lifting slide 3. This is in the locked position with his one Arm 15a opposite a stop 16 on the respective suspended basket 4, 4 '. A certain distance is provided between the lower end of the arm 15a and the stop 16, but this distance is smaller than the vertical height of the hooks 5, 7.
  • the other arm 15b of the locking bolt 15 carries a roller 17, which with a in the The control cam provided near the lower end of the guide mast 2 interacts.
  • the control curve 18 is shaped such that the locking bolt 15 is pivoted into its unlocked position in the direction of arrow 8 shortly before reaching the lower end position of the lifting slide 3 and releases the stop 16.
  • the conveyor cage 4 is thus suspended from the lifting carriage 3 and is carried solely by the support arm 8.
  • the suspended conveyor basket 4 can then be pivoted to the side in the direction C by 90 °.
  • the second conveyor cage 4 ' is initially in its loading and unloading position shown in FIG. 1 to the side of the guide mast 2.
  • the first conveyor cage 4 was moved up and down with the lifting slide 3, it was loaded with scaffolding parts or other material .
  • the support arm 8 ' By pivoting in the direction of arrow D, it can be pivoted on the support arm 8 'in front of the now empty lifting carriage 3.
  • the support arm 8 ' thus reaches the position shown in broken lines.
  • the lifting slide 3 is also raised so far that the roller 17 of the locking bolt 15 has left the control curve 18 again and the locking bolt 15 thus assumes its locking position shown in FIG.
