Definitions

  • the present invention relates to material lifts, of the kind of those formed by a ladder or beam structure serving as raceway for a carriage capable of supporting a load, and comprising a motorized cable winch used to tow the carriage along of the raceway, the cable which connects the winch to the carriage passing over a return pulley located on the head of said structure. More in particular, the invention relates to a material hoist of this kind, in which the carriage carries a tilting skip, capable of receiving a material such as concrete that can be spilled by tilting the grab.
  • Material lifts of the kind considered here known by example by document FR 2683516 A, allow to bring charges in height, from the ground, in particular to raise construction up to the roof level of a building, during construction or renovation.
  • the present invention aims to solve this problem, by providing a hoist of the kind concerned, including the receptacle or load support, in particular consisting of a tilting skip, can both be brought very close to the ground when the cart is in the end position of low stroke, and be brought very forward when the carriage reaches its high end position, the proposed technical solution remaining simple from the point of view of structure and operation.
  • the invention provides a carriage configuration, allowing to a part (movable frame) of this carriage to describe a race extra, and in particular an extra run down, bringing the support or load receptacle very close to the ground, without prevent this support or load receptacle from reaching also very before, when the carriage arrives in the upper end position.
  • the mechanism proposed for this purpose is particularly simple, since it does not requires no special means to move the movable frame relatively the main chassis of the trolley, the cable activated by the winch sufficient to obtaining all displacements, in combination with simple limit stops and contacts.
  • document EP 0341563 A already provides, in a material lift of the kind concerned, a carriage comprising a chassis main, mounted rolling on the raceway formed by the structure ladder, and a frame movable in translation on the main chassis, parallel to the raceway, but this document does not indicate the purpose of this provision, and in particular it does not explain in which operating circumstances the movable frame would move relative to the main chassis; the movable frame being connected by a spring to the base chassis, it is apparently a simple suspension.
  • this document does not specify how the cable traction is linked to the carriage; in particular, it is not specified whether this cable is attached to the base frame or the movable frame, while this point is particularly important for determining the operation of the material lift according to the present invention.
  • the movable frame comprises advantageously lateral guide rollers, mounted in main chassis side rails; these slides are closed, at less at their upper ends, to form stops which position the movable frame, relative to the main chassis, in its high or advanced position, and which allow the chassis to be driven main through the framework.
  • the movable frame also advantageously comprises, in its central part, a tab or clevis used for mooring the end corresponding cable operated by the winch.
  • the chassis main carriage consists of two opposite "U" half-chassis, assembled together in a removable manner by their respective side members, formed by angles, the meeting of these angles forming the side rails, in which the movable frame is trapped when the two half-frames are assembled together, while the separation of these two half-chassis allows the assembly or disassembly of the mobile frame.
  • Figure 1 shows, schematically, a material lift which includes a structure 1 in the form of a ladder or beam, and more particularly, in the example illustrated, in the form of a truss of triangular section (see also figure 2).
  • Structure 1 is made up of a succession of elements fitted into each other, in particular rectilinear elements, and a curvilinear connecting element or “Knee pad” 2.
  • the lower end of structure 1 rests on the ground 3, while its upper part is located at the level of the roof of a building 4 under construction or renovation. Thanks to the toggle 2, the upper element (s) of structure 1 have a inclination adapted to the slope of the building's roof 4.
  • Structure 1 forms, by two of its members 5, a path of rolling for a carriage 6, and more particularly for a carriage equipped with a tilting skip 7, pivotally mounted around an axis horizontal 8.
  • a motorized cable winch 9 is provided at the lower end of the structure 1.
  • the head 10 of the structure 1, opposite the winch 9, is equipped with a return pulley 11, over which passes a cable 12 which is operated by the winch 9 and which is used to tow the carriage 6 along the bearing 5, the end of the cable 12 being linked to the carriage 6 (in a way specified below).
  • the main chassis 13 is itself constituted, like the shows FIG. 4, of two opposite half-chassis in “U” shape 15 and 16, each half-frame 15 or 16 comprising two longitudinal members, formed by angles, connected at one end by a crosspiece.
  • the two half-chassis 15 and 16 are joined and assembled to each other, by screwing, so that their corresponding longitudinal members, joined together, form two slides lateral 17, closed at their upper and lower ends by the sleepers.
  • One of the half-chassis 15 carries lateral guide rollers 18, grouped in pairs, which take place on either side of the path bearing formed by the structure 1.
  • the movable frame 14 has two triangular side parts 19, interconnected by crosspieces 20.
  • the two lateral parts triangular 19 carry, respectively, two lateral bearings 21 of support and pivoting of the tilting skip 7, the latter being provided side pins resting in the bearings 21.
  • the movable frame 14 comprises lateral guide rollers 22, which are engaged and trapped in the side rails 17 of the chassis main 13. Given the length of these slides 17, the frame mobile 14 is movable in translation, on the main chassis 13, between a high or advanced position A (figure 3) and a low or moved back position B (see Figure 1, below). These two positions are defined by stops resulting from the elements (crosspieces) which close the slides 17 at their upper and lower extremities. In particular, an upper stop is formed by the ends of a cross member 23 of the half-frame 15.
  • One of the crosspieces 20 of the movable frame 14 comprises, in its central part, a tab or clevis 24, projecting from the side opposite the tipping body 7.
  • the end of the cable 12, actuated by the winch 9, is moored to lug or clevis 24, via a pin transverse 25, a parachute device being provided at this location.
  • the movable frame 14, retained by the cable 12 occupies its high or advanced position A, relative to the chassis main 13, which occupies its lowest position by the effect of gravity.
  • the actuation of the cable 12 by the winch 9, in one direction or in the other drives the movable frame 14 up or down, the chassis main 13 "following" the frame 14.
  • the carriage 6 is driven by through its movable frame 14, which carries the tilting skip 7.
  • the main chassis 13 is first stopped by a stop. From there, the movable frame 14, moved directly by cable 12, can still describe a certain race towards the bottom, bringing it (relative to the main chassis 13) in its position low or remote B.
  • the tilting skip 7, carried by the movable frame 14, is thus brought itself into a low position, very close to the ground 3, which facilitates its loading, in particular its filling with concrete, according to arrow F, from a concrete mixer (not shown).
  • the functioning of the winch 9 is controlled by contacts of limit switch, not shown, which intervene when the carriage 6 reaches its lower and upper limit positions.
  • the lower limit switch is arranged to be actuated by the movable frame 14 (and not by the main frame 13), to allow frame 14 to carry out its additional downhill stroke, while the chassis 13 is already stopped in its lowest position.
