Definitions

  • the invention relates to a box-shaped assembly scaffold with a lifting platform, which is longitudinally upright on supports arranged on a frame and is continuously height-adjustable, which comprise a cable winding device arranged on the lifting platform for synchronous winding and unwinding of lifting cables or the like, two lifting cables in each case common rope are connected to each other and guided over a common rope drum.
  • Such a mounting frame is known from EP-A-0 219 883.
  • This assembly scaffold which has already proven itself extremely well in practice, a high degree of stability is achieved at any height of the lift with relatively little design effort, the lift being "rigidly" connected to the chassis at any height.
  • This known assembly scaffold has the additional advantage of a light construction due to the use of a cable construction.
  • the height adjustment of the assembly scaffolding requires a certain effort, due to the special cable guide although due to the pulley effect achieved, this well-known lifting platform can be adjusted very easily with relatively low drive power at high loads.
  • the transport of this assembly scaffold for example when changing the place of use, is relatively cumbersome. Accordingly, the frame with the supports arranged thereon for the transport and the lifting platform are to be transferred to or from the loading platform of a transporter or the like each time, securing the assembly scaffold against slipping during transport by additional, often time-consuming measures is indispensable.
  • the object of the invention is to further develop the known device in such a way that, while maintaining high stability and lightweight construction, improved handling for the height adjustment of the lifting platform and the transport of the assembly scaffold as a whole achieved and at the same time operational and functional safety is increased.
  • the measures according to claims 3 to 18 lead to a cable drum for the assembly scaffold according to the invention, and also independently of the measures according to claims 1 and 2, which works particularly efficiently and above all functionally reliable.
  • the cable drum is arranged approximately parallel to the transverse or longitudinal sides of the mounting frame and is equipped with two roller bodies which can be driven by a continuous shaft and each take up two lifting cables connected to one another to form a common cable. This results in a synchronous and uniform winding and unwinding of the hoisting ropes over the entire height adjustment range of the lift.
  • the arrangement of a drive between the two roller bodies of the cable drum according to the features of claim 6 has the advantage of a direct, moreover uniform application of force, which ultimately results in an improved drive performance.
  • each roller body is provided on the outer circumference with receiving grooves for the lifting rope windings, so that the lifting ropes or The ropes, which are connected to each other by two lifting ropes, are arranged and are immovably received by the corresponding roller body.
  • each roller body is surrounded by an axially movable pressure shell for the hoisting ropes, so that jumping out or the like. Individual hoisting rope windings are prevented from the corresponding receiving grooves of the roller bodies.
  • the inventive adaptation of the diameter of the pulleys to the width of the supports according to the feature of claim 21 has the advantage that the lifting cables are guided in close proximity to the supports without directly touching them.
  • an extremely compact construction of the support with associated hoisting rope is achieved, while largely avoiding additional torsional forces or moments of force acting on the respective support.
  • a particularly favorable distribution of the forces, which are caused on the one hand by the dead weight of the lifting platform and on the other hand by further weight loads due to personnel and auxiliary equipment or the like being raised or lowered, within the assembly scaffolding on the individual supports can also be achieved by the arrangement according to the invention of the individual deflection rollers to each other and this on the individual components of the entire assembly scaffold according to the measures of claims 22 to 26.
  • both the guiding accuracy and the smooth operation of the lifting platform when it is displaced along the respective support are further improved with little design effort. Since this design also prevents the lift from tilting on one or more of the supports from the outset, its overall height adjustment is extremely smooth even with one-sided loading.
  • the operational safety of the assembly scaffold according to the invention is increased in that the lifting platform is provided with braking devices in accordance with the features according to claims 31 to 39, regardless of the measures according to the preceding claims. Since, in the context of the invention, each support is assigned a braking device which automatically and immediately triggers when the corresponding hoisting rope breaks, the lifting platform can be kept at the current height at any time.
  • the structural details according to the invention in particular by the coupling of the spring-loaded brake shoes with the lifting cable guided over the so-called first deflection pulley, ensure that the brake shoes when the hoist rope breaks, ie when the rope tension ceases, due to the counteracting spring force and last but not least due to the weight of the lift, they reliably engage with the respective support.
  • the frame is provided with support sections in accordance with the features of claims 56 to 64 , the upper ends of which are each connected to the lower end of each support via a hinged joint or the like.
  • Each functionally hinged support hinged to the corresponding support section can be locked without play in the extension of the support section and can be folded into the plane of the frame for transportation purposes just as quickly as after releasing the lock.
  • the structural measures for the folding joint according to the invention by means of which play-free locking of the respective support on the assigned support section is ensured, are of great importance for a functionally reliable assembly scaffold.
  • the supports according to the invention can be inserted into tubular holding devices of the frame in accordance with the measures according to claims 40 to 44 and can be removed from them for transport purposes.
  • the mechanism according to the invention for releasing the press fit between the respective support and tubular receiving device is of particular interest. Because of the eccentric provided, the respective support with its tapered end is simply and quickly pressed out of the tubular receiving device or out of the mast quiver when it is rotated by means of a dismantling lever. In this way, the assembly scaffold according to the invention can both be assembled without difficulty and, in turn, conveniently dismantled to form a compact transport unit.
  • support feet are provided in the corner regions of the frame, which are designed to be extendable downwards at least beyond the maximum height and width dimensions of the single-axle trailer chassis and can be moved out laterally from the frame.
  • the support feet are each provided with their own impeller, so that the assembly scaffold according to the invention remains movable even after the single-axle trailer chassis has been removed. Not least because of the improved handling resulting therefrom, the assembly scaffold according to the invention can be used universally.
  • the 1 to 5 comprises a frame 1 which is rectangular in plan and has the same shape as a lifting platform 2 with a platform 3.
  • the lifting platform 2 is arranged together with the platform 3 upright on the frame 1 and in the corner areas 4 Supports 5 continuously adjustable in height by lifting means, ie can be raised and lowered as required.
  • the platform 3 is surrounded by a railing 6, which is connected, for example, by a plug connection to the lifting platform 2, the design of which can be of the most varied types (cf. FIGS. 1, 2; 4, 5).
  • 4 support feet 7 are arranged on the frame 1 in each of the corner areas, which can be extended by means of locking spindles 8 of conventional design.
  • a single-axle trailer chassis 9 is provided for transporting the assembly scaffold, which may be moved under the frame 1 of the assembly scaffold and then releasably connected to it and vice versa.
  • the lifting means have a rope winding device arranged on the lifting platform 2 for the synchronous winding and unwinding of lifting ropes 10, each lifting rope 10 crossing according to FIGS. 4 and 5 on a transverse side 11 and on a longitudinal side 12 of the assembly frame with a further lifting rope each diagonally across the surface .
  • the support feet 7 according to FIGS. 1 and 4 in the corner regions 4 of the frame 1 can be extended at least beyond the maximum height or width dimensions of the single-axle trailer chassis 9 or can be moved out laterally from the frame 1. While the extension of the support feet 7 in the vertical direction is carried out by extending the locking spindles 8, the support feet 7 are displaced in the horizontal direction from the plane of the longitudinal sides 12 of the mounting frame, for example by tubular support parts (not shown) rigidly connected to each support foot 7 . These carrier parts are longitudinally displaceably received in corresponding receiving parts 13 (cf. FIGS.
  • the support feet 7 are each inclined from the frame 1 towards the outside in the vertical direction. Such an inclined position of the support feet 7 ensures play-free support of the assembly scaffold as a whole, especially on an uneven floor surface. Furthermore, the support feet 7 are each provided with an impeller 15, so that the mounting frame itself remains movable after removal of the single-axle trailer chassis 9. In order to be able to secure the assembly scaffold against rolling after removal of the single-axle trailer trolley 9, the support feet 7 or the locking spindles 8 can each be individually extended at least until each impeller 15 is lifted off the ground.
  • the wheels 15 are arranged on the corresponding support feet 7 such that the wheels are in contact with the ground through the uniaxial trailer chassis 9 while the mounting frame is being driven under. In this way, it is easy to make position corrections between the single-axle trailer chassis 9 and the assembly scaffold due to its movability even during the coupling process without difficulty.
