Definitions

  • the invention relates to a construction hoist, in particular a rack and pinion hoist, with a load-carrying means that can be moved on a mast, in particular a rotating platform, which is provided with an armor that is pivotally mounted on the floor of the platform and has an access that is pivotably mounted on the floor of the platform, with the armature pivoted from its vertical starting position in a substantially horizontal position pivoted loading flap forms a transition from the driving platform to a building.
  • Construction lifts especially rack and pinion construction lifts, such as Known by DE 41 26 768 C2, are used for the transportation of goods on the construction site, in particular for lifting or lowering such goods.
  • a construction elevator usually consists of a basic unit. This is provided with a base frame and a base mast element which is largely attached at right angles to it, and which can be extended by further elements to the desired height of the construction elevator, along which a load suspension device or the like can be moved by means of a drive.
  • the mast elements are provided with a continuous rack, along which the load suspension means can be moved by means of the drive provided with a gear wheel.
  • Such a construction hoist or its load suspension device or the like is usually loaded and unloaded via the loading flap or ramp pivoted into an essentially horizontal position, which serves as height compensation and at the same time prevents materials from falling down in its vertically folded up position.
  • the swing-out loading flap bridges the Distance between the driving platform and the building; its front end rests on a scaffold or the ceiling of a building.
  • the invention is therefore based on the object of providing a construction hoist of the generic type which corresponds to the safety requirements, is easy and safe to operate and assemble on site, and enables ergonomic loading or unloading of the load handling device or the like.
  • the loading flap on the building side is assigned a barrier which can be pivoted about a horizontal pivot parallel to the building level and which, in the swung-open position, blocks the loading flap which has been folded down as a transition to the building against folding back. Due to the interlocking opening and locking mechanism between the loading flap pivoting into the walking / loading position and the barrier barrier is achieved according to the invention that the loading flap must be open, ie must be in its walking / loading position before the barrier can be opened, and conversely the loading flap can only be closed if the barrier has been closed beforehand.
  • An embodiment of the invention provides that the pivot bearing is arranged on a frame of the building entrance and a post extension of the barrier, which extends downward beyond the pivot bearing.
  • the barrier designed in frame construction also provides a handrail and a knee bar thanks to the horizontal frame struts.
  • the deep storage of the pivot point of the barrier on its extended outer post results in several advantages, such as, in particular, a shorter and lower arm movement when opening, which can further be improved by moving the handle toward the center of the barrier.
  • Lowering the pivot bearing results in a lower swivel path and height movement of the barrier, which consequently does not swing out so high that it can also be arranged recessed in the building opening. Nevertheless, it can be opened completely or swung open without touching the ceiling.
  • the swivel path has a maximum height of only 2 m; when closed, the barrier secures a height of 1.1m.
  • Narrower barriers are lower by the corresponding difference.
  • the opening or the building entrance need not be greater than the width of the closed barrier.
  • walls, supporting beams or pipes are suitable and advantageously also horizontally or vertically mounted scaffolding pipes.
  • pipe couplings fixed to the frame allow the barrier to be moved sideways.
  • the barrier according to the invention is suitable in combination with both a drive-through platform, a pivoting platform and a rotating platform which is used primarily in smaller construction elevators.
  • a baseboard which is rotatably supported against a preload.
  • the skirting board is held in vertical position by spring force; it can only be folded down to the construction site.
  • the skirting board is folded down by the loading flap, which rests with its front end on the building side.
  • the foldable baseboard prevents the barrier from opening, because when it swings open the extension of the vertical outer post almost to the floor strut would hit the raised baseboard, which is in the swivel path of the tier barrier. Only when the opened and swung-out loading flap falls on the skirting board is it pressed down and can no longer block the path of the barrier to open it.
  • an additional embodiment provides a switch on the on-site frame of the barrier which is electrically connected to the drive motor of the platform and interrupts the control current when the barrier swings up.
  • the control current is interrupted while the front edge of the barrier is in, for example, the U-shaped guide of its on-site frame, i.e. at a time when the barrier is still securely closed.
  • the control current can alternatively be interrupted even earlier, either by lowering the baseboard, opening the loading flap, swiveling in the turntable, or pulling on the rope that is required to release the turntable.
  • the latter version would be the earliest possible shutdown and possibly the safest in connection with the on-site shutdown by the baseboard.
  • a preferred embodiment of the invention provides a side protection connected to the loading flap depending on the movement and securing the transition to the building when the loading flap is folded down.
  • a side protection designed in a frame construction is advantageously movably mounted on the two vertical posts of the stage access, the side protection frames being connected to the loading flap via a respective articulated lever and one of which is provided with a locking lever.
  • the side protection is also produced at the same time.
  • the pivot points of the tailgate mechanism thus achieved are chosen so that the tailgate is over a considerable angle Can open 90 ° and the two side protection frames in this case move only a little away from their position that they would take if the loading flap was opened by 90 °.
  • the side protection is ensured by the construction as a rectangular frame, which replaces the otherwise required handrails and knee rails when the loading flap is open.
  • the loading flap itself is designed with web plates that are angled on its sides and serve as baseboards.
  • the grid lever allows the loading flap to be brought into different positions, so that the size of the load handler or the platform can be adapted to the space requirements of different wheelbarrow sizes in relation to their bars.
  • the side baseboards still provide the necessary side protection.
  • the locking lever enables the maximum opening angle of the loading flap to be set so that it can be used for vertical transport, i.e. prevents parts from falling when lifting or lowering. It is possible to mount a limit switch on the loading flap, which interrupts the elevator movement when a maximum opening angle is exceeded.
  • the side protection frames are located on both sides above the loading flap, it is recommended that only one side if possible, i.e. to provide a side protection frame with a locking lever to avoid operation with both hands.
  • the side protection combined with the loading flap mechanism described can advantageously also be provided on fixed drive-through platforms, since it automatically ensures the required safety distance after the loading flap has been closed.
  • the locking lever which is locked in a desired position, holds the loading flap in a safe position, which was not the case with the chains previously used because they are not always hooked in as carefully as they should be.
  • a side guard provides that complementary hinged doors are arranged above the loading flap on the vertical posts of the access, filling the access upwards. If the driving platform is surrounded by a height of, for example, 1.1 m, the loading flap fills in its vertically swung-in position Position 0.6 m out, and the hinged doors hinged directly above the loading flap are correspondingly 0.5 m high.
  • the wing doors consisting essentially of only one frame serve as a handrail with their horizontal upper frame strut and as a knee rail with their lower horizontal frame strut located at a height of 0.6 m.
  • the wing doors are provided with a latch.
  • These can advantageously be designed as swivel levers that can only be moved forward, which project downward beyond the lower edge of the hinged doors and lie behind the upright loading flap.
  • the closed hinged doors therefore find their abutment on the locking latches, which can only be moved outwards or forwards.
  • the locking latches move forward as soon as they hit the top edge of the vertically positioned loading flap. After the locking latches have moved over the top edge, they fall down and lie against the loading flap from the inside of the platform.
  • the loading flap is bordered with web plates on its two longitudinal sides, lateral baseboards of, for example, 15 cm in height result in the transition position of the loading flap. This secures a construction site scaffold - handrail, knee rail, skirting board - also in the area of the open loading flap.
  • a revolving platform which is rounded on its head side is provided in the barrier walls with slots arranged at the height of wheelbarrow bowls.
  • the stage can be set at a minimum distance of 1 to 2 cm in front of the Screw in the wall of the building, which allows the mast structure and the anchors required to fix it to be installed from the stage without the need for an expensive assembly bridge.
  • the opened loading flap can rest on the on-site ceiling or on scaffolding.
  • the loading flap must in any case rest on the ceiling or scaffolding for about 10 cm, so that a mobility of 10 cm can be maintained for the assembly of the mast. This is also necessary because the building wall can flee in one direction or the other or the mast is not always fully aligned.
  • Construction lifts with a payload of 500kg require a platform size that allows the transport of two wheelbarrows, i.e. the driving platform must be about 1.4 to 1.6 m wide and at least as long. In the case of construction lifts suitable for the transport of only one wheelbarrow, a width of 0.8 to 1.0 m is sufficient.
  • the depth of the stage has a major impact on the statics of the mast and the stability of the elevator. If the platform of a free-standing elevator becomes larger, not only are the support bars to be extended, but their cross-section must also be enlarged, i.e. the basic framework becomes much heavier. Along with this, the mast construction also has to absorb greater bending forces and consequently also becomes heavier.
  • the full payload must be stored on 75% of the platform area, in each case in the most unfavorable position for the mast and stability.
  • this has a decisive impact on the statics and stability.
  • the platform With the design of the turntable rounded on the side remote from the stage access, the problem that arises when transporting wheelbarrows is otherwise due to the handlebars having a height of 40 to 65 cm.
  • the platform enlarged to a depth of 1.6m, can be manufactured inexpensively from standard sheet metal dimensions, which has the advantage that long weld seams can be avoided.
  • the driving platform has a dimension suitable for all types of wheelbarrows; the length of the wheelbarrows can be up to 1.6m with a bowl width up to 75cm.
  • the fulcrum of the rotating platform is eccentrically displaced away from the mast.
  • the wheelbarrows can be moved forward by approx. 15 cm.
  • the rotating stage which maintains a distance of 0.5 m, can be turned in front of the building wall, because the eccentric bearing causes the driving platform to pivot backwards - according to the above example - by 7.5 cm.
  • the eccentric shifting of the pivot point in combination with the slots or openings in the sides of the rotating platform makes it possible to reduce the size of the platform floor for static, weight and cost reasons, in the driving position always a distance of 50 to 60 cm from the building wall or scaffolding to be observed, to turn the stage in close to the wall of the building, to set the fastening anchors from the driving platform and the loading flap up to max. 20cm on the building ceiling or the scaffolding for safe loading and unloading.
  • an approx. 65cm long loading flap and 20cm support on the building ceiling or the scaffolding floor there is a distance between the building and after the driving platform has been screwed into the loading position the driving platform of approx. 45 cm, ie a distance that lies comfortably in the handling area of, for example, an operator installing the anchor.
  • a preferred embodiment of the invention provides that the loading flap can be adjusted in different inclined positions. Since the loading flap can thus be tilted even when closed, the eccentric mounting of the rotating platform could possibly be unnecessary. Tilting is of particular interest for turntables with which only one wheelbarrow is to be transported. With some common wheelbarrows, the handlebar handles are over 60cm high, i.e. above the height of the upright tailgate, the tailgate can be closed completely or - depending on the construction of the spars - despite a slanted position of the tailgate and the slightly open gullwing doors, a minimum protective height of 60cm can be achieved on all sides, namely through to the front or top edge the tailgate reaching side web plates or baseboards of 15cm height.
  • Wheelbarrows with low, long spars allow a sufficiently steep closing, whereby the raised baseboard at least partially reaches or even exceeds the height of almost 60 cm.
  • the baseboards reduce an open triangle towards the side wall to a minimum.
  • the triangles, which remained open on the sides, could even be closed completely if the side wall of the stage was pulled forward around the resulting opening or the baseboard was raised accordingly.
  • partially closed wing doors or side protection frames already offer additional side protection with respect to a triangle between the side wall and the baseboard.
  • the frame-like gullwing doors open under the bars and settle in front of the closed loading flap.
  • the loading flap can be adjusted by means of a lever linkage supported by spring force with a handle ending at the height of an operator's hand.
  • a lever linkage supported by spring force with a handle ending at the height of an operator's hand.
  • the movement is supported by the spring force both when opening and when closing.
  • a movable mounting of the handle is possible, with stops limiting the movement to the required extent.
  • the hand lever is always pressed in the direction of the lock by spring force. Any number of latches and thus inclined positions can be provided, so that all possible types of wheelbarrows or similar devices can be loaded.
  • the opening angle of the tailgate should be limited to 30 o ; a noticeable further opening or inclination would also prevent the stage from turning in.
  • the loading flap can be brought into an almost vertically hanging position by means of the lever linkage and, moreover, can be brought into a position that is shifted under the stage.
  • a forklift truck is increasingly being used on construction sites, for whom the loading flap would otherwise be very rearward for loading or unloading the turntable, since the truck with the usual fork lengths cannot place the pallet on the platform.
  • the handle for adjusting the different opening angles of the loading flap could also be mounted so as to be movable and have stops which limit the movement to the required extent.
  • Such a movable lever could always be pressed in the direction of the latch by spring force. In this way too, any number of latches are possible, so that in turn all kinds of wheelbarrows or similar devices can be loaded.
  • the fall arrest device can, according to the invention, consist of a tube which is immersed in a guide when the stage having an eccentric fulcrum is screwed into the mast structure and is resiliently suspended and has a tip. Simultaneously with the turning of the platform, the holding means in the form of the safety tube is pushed into the mast structure and immersed in it. Due to the resilient suspension of the tube in the middle of the guide area, the tube tip can deflect in all directions when it meets a round bar of the mast framework.
  • a locking plate could, for example, be immersed in the mast as a holding means.
  • This is provided with a base frame 2, a base mast element 3 arranged largely at right angles thereon, on which further mast elements 4 can be fixed, and a driving platform 5 which can be moved along the base mast element 3 and the further mast elements 4 connected thereto by means of a drive.

  • a locking latch 22 is pivotally mounted at the bottom, in such a way that the locking latch 22 can only move outwards or forwards in the direction of the arrow 23 according to FIG. 13b; pivoting in the other direction is prevented by an abutment 24 arranged on the wing doors 17a, 17b.
  • the wing doors 17a, 17b are driven by the force of a torsion spring arranged on the pivot axis 25 26 acted upon and kept closed (see FIG. 13a).
  • a lever linkage 28 is arranged on the driving platform 5, 105 and ends with a handle 29 at a height above the barrier 8 that is easy for an operator to reach.
  • a spring 31, which engages the lever linkage 28, is arranged approximately at the level of the platform 30 for easier opening and closing of the loading flap.

  • FIG. 10 shows an embodiment of a barrier 45 opposite the access 9 of a screwed-in driving platform 5 or 105 and opened in the example. It consists of a frame-like frame which provides a handrail 46 at the top and a knee bar 47 at the bottom.
  • the barrier 45 is pivotally mounted in a frame 49 inserted into a building entrance 48 and made of profiled beams.

  • the closed position of the barrier 45 in FIG. 11 The lowered arrangement of the pivot bearing 53 requires a lower arm movement of the operator to open the barrier 45; the displacement of the handle 55 toward the center of the tier barrier 45 also contributes to this, as shown in the dashed position of the handle 55 in FIG. 10.
  • the swivel radius or swivel path 56 is shifted downward, so that the barrier 45 can also be set back in the building entrance 48, if necessary, without touching the building ceiling when swung open.
  • the movement mechanism of the pivot bearing 53 is located in front of the U-shaped frame 49, so that the barrier 45 is pushed laterally in front of the building wall 41.

FIG. 16) - a baseboard 62 held in a vertical position by spring force 61; This can only be pushed down to the building site. This is caused when the tailgate 16 of the turntable 5 or 105 lies with its front end on it, which is the case when the tailgate 16 is in its position Transition from the entrance 9 of the revolving stage to the building entrance 48 and lies up with its front end on the building side (cf. also FIG. 27). The principle of operation can be found in the diagram shown in FIG. 17.
  • the interplay of the loading flap 16 of the platform 5 or 105 and the barrier 45 is such that the loading flap 16 must first have been lowered in order to depress the baseboard 62 before the barrier 45 can be opened, and likewise the barrier 45 must first be closed , before the tailgate 16 close again, ie in their position blocking access to the driving platform 5 or 105.
  • the side protection frames 78 or the wing doors 17a, 17b automatically open, so that side protection is also ensured before the barrier 45 is opened (see FIGS. 27 and 24a and 24b).
  • the vertically erected baseboard 62 prevents the barrier 45 from being able to be opened before the loading flap 16 has depressed the baseboard 62; because the post extension 54 of the barrier 45 would be against the side edge of the baseboard 62 and would consequently be prevented from being able to be swung open (cf. FIG. 11).
  • the baseboard 62 is in the pivot path of the barrier 45.
  • the safety with regard to the dependence of the opening of the loading flap 16 or the barrier 45 could further be supported by the fact that either a limit switch 63, which monitors the pivoting movement of the barrier 45, the pivot bearing 53 (see FIG. 12b) of the barrier 45 or a limit switch 64, the pivot pin or the pivot bearing 59 of the baseboard 62 (see FIG. 12a). If the loading flap 16 has not yet been swung out, a pushing down of the skirting board 62 or swinging up of the barrier 45 from the construction side, causing a rotary movement in the bearings 53 or 59, would lead to an interruption of the control current for the driving platform 5 or 105 and that Prevent starting the aerial platform.

  • the long baseboard section 62a is only slightly shorter than the width of the loading flap 16, so that when the loading flap 16 is folded down, the narrow baseboard section 62b is also depressed and releases the storey barrier.
  • the narrow baseboard section 62b is held in the vertical position by a separate spring 61.
  • a flat iron 65 held vertically by the force of a spring 61 (cf. FIG. 19) with a tube or sheet metal 66 welded parallel to the baseboard 62 could also take over the securing function.
  • the loading flap of the driving position I (cf. FIG. 25a and the schematic dash-dotted line in FIG. 26a) via a base-side swivel 67 into its unloading position II (cf. FIG. 25b or the driving platform shown in solid lines in FIG. 26a) turned-in driving platform is in its upper Unloading positions II by a fall arrest 68, as shown in FIGS. 25a to 26a, prevented them from opening by more than approx. 110 ° in order to rule out unloading or loading at shoulder height, for example, over an abyss.
  • the fall arrester 68 (cf. FIGS.
  • 26a and 26b) for a cable elevator consists of a tube 72 which is formed at the front with a tip 69 and is suspended in the middle in a guide 71 with a spring 70 at the front; the rear tube end is supported in a bearing 73 of the eccentrically offset axis of rotation 74 (cf. FIG. 26b).
  • the driving platform 5 or 105 is screwed in from the driving position I into the unloading position II, the securing tube 72 (see FIG. 25) previously located under the driving platform floor 30 reaches a position projecting relative to the driving platform (see FIGS. 26a and 26b). and immersed in the mast construction 3; 4. Due to the suspension of the securing tube 72 via the spring 70, the tube tip 69 can deflect in all directions when it strikes a round bar of the mast framework 3; 4 and become lodged in the mast structure.
  • An eccentric rotary movement of the rotating platform 5 or 105 allows the driving platform 5 or 105 to be screwed in close to the various platform sizes and the goods to be transported, for example wheelbarrows the building wall 41 or a scaffolding arranged in front of it.
  • the eccentricities R 1 , R 2 are selected so that after the driving platform 5 or 105 has been fully screwed in, there is a distance of approximately 0.4 m between the building and the driving platform; this small distance from the building wall 41 makes it possible to mount the required anchors easily from the driving platform. As shown in FIGS.
  • the eccentric rotary movement also creates the necessary space to be able to use the handles 40 to protrude wheelbarrows 39 protruding beyond the loading flap 16 on suitably adapted movement paths or radii 42 with the driving platform in front of the screw ; the same applies to a loading flap 16 which is fixed in a forward projecting inclined position.
  • the maximum use of the loading area provided by the driving platform floor 30 of the driving platform 5 or 105 by adjusted wheelbarrows can be done under Consideration of the movement paths 42 or turning radii due to the eccentricities R 1 , R 2 of the driving platform 5 or 105 also further improve that in the walls 8 of the driving platform 5 or 105 at the level of the bowls of the wheelbarrows slots or openings 75 (vg. Fig. 23b) are arranged, through which the corners 76 of the bowls can protrude from the wheelbarrow set.
