Definitions

  • the invention relates to a roller shutter-like pit cover consisting of a band of hinged supporting members which are movably supported in the longitudinal direction on two upper support rails arranged on the pit longitudinal edges, with two sprocket-like drive wheels connected by a transverse shaft in the upper region of a pit end and one with which Transverse shaft-coupled drive motor which can be driven in both directions, the drive wheels being in drive engagement with the support members or joint arrangements connecting them, further with lower deflection devices for the support members arranged on the same pit end near the pit floor, and also connecting lower linear guide rails which are parallel to the support rails , wherein the lower deflection devices comprise arc-shaped guide rails which connect the lower guide rails to vertical guide rails adjacent to the pit end wall in each case.
  • Such a cover is known from DE-A-2 646 395.
  • the known cover uses four deflection elements for two endless chains, to which the support link belt is attached. If the chains are tight enough are held, the support link belt can be pulled in both directions. This mode of operation is very reliable. The known cover has therefore proven itself quite well.
  • a covering device of a similar design is known, with three separately movable supporting link belts lying next to one another.
  • the middle support link belt corresponds in operation to the aforementioned prior art, the two outer support link belts are divided into longitudinal halves and each have only one upper driven deflection wheel for chain strands.
  • the support members are pushed when the pit is closed. When the pit is open, the supporting link belts hang freely downwards at the front.
  • This design requires deep shafts for the hanging link belts in long pits.
  • the object of the invention is to make the cover of the type mentioned simpler and in such a way that an arbitrarily long pit can be covered with a one-piece link belt without additional shafts or pit extensions being required and an absolutely safe operation being ensured.
  • the new cover avoids endless chains and reduces the number of deflection elements. A single pair of idler wheels on the drive shaft is sufficient.
  • the link belt is guided in an extremely space-saving manner and the uninterrupted guide rail arrangement ensures a safe operation even when pushing Working without the link belt building up and jamming.
  • the lower deflection devices each have a deflection wheel, which is in constant drive connection with the drive shaft by means of at least one endless connecting element, and that the deflection wheel is designed as a drive wheel for the supporting members.
  • the inner lower curve guide is then omitted and thanks to the synchronization of both drive wheel pairs, the hanging part of the link belt is relieved when pushing.
  • This version is particularly suitable for long pits.
  • a low-friction sliding strip is arranged on the support rails, on which the support members rest and that the guide legs are arranged at such a height above the support rails that the support members resting on the sliding strips or their sections or lugs lie a short distance below the lower surfaces of the guide legs.
  • the sliding strip ensures low-friction sliding with great smoothness.
  • the link belt tends to lift off the sliding strip and the sections or projections, which are also preferably designed to be low-friction, come to rest softly on the guide legs, which is associated with a reduction in the sliding resistance.
  • the approaches preferably consist of roles.
  • end plugs with slots are inserted into the hollow support members, into which the guide legs engage with vertical play.
  • the chain links each have a length equal to the width of the support links and the joints are located between the support links.
  • the joints are each arranged in the middle of the width of each support member and the sections of the support members or support member projections which underlie the upper arch guides and / or the lower arch guides are convex in cross section. This design enables the connection of circular guides in the deflection area while avoiding a large radial play in the guide area of the support members.
  • An assembly pit 10 has a widened area 12 at one end (FIGS. 3, 4).
  • longitudinal support rails 14 are concreted in the upper area, but at a distance from the level 16 of the adjacent hall floor, on which low-friction plastic strips 18 are fastened, on which a number of support links are supported, which are connected on the bottom side by means of two chains 22 to form a support link belt 24 are.
  • the chain links 26 have a length equal to the width of each of the support links 20 and the joints 28 of the chain links 26 are each between two support links 20 ( Figures 1 to 6).
  • Vertical mounting rails 30 are fastened to the two side walls of the pit widenings 12, on which an upper shaft 32 and a lower shaft 34 are rotatably mounted.
  • Each of the two shafts 32, 34 carries two sprockets 36 and 38, the circumferential recesses with the pivot pins of the joints 28 of the ket ten 22 work together.
  • a horizontal cross rail 40 is fastened to the two vertical mounting rails 30 and carries a drive motor 42 in a hanging construction, which is designed as a gear motor and is penetrated by the upper shaft 32.
  • a guide rail 44 is welded to the support rail 14 with a U-profile open to the interior of the pit, the upper edge of which is flush with the adjacent hall floor 16.
  • the guide rail 44 is laterally offset outwards with respect to the center of the support rail 14, such that the support members 20 delimit a gap of approximately 5 mm with the upper legs of the guide rails 44.
  • the height of the profile of the guide rails 44 is equal to the sum of the height dimensions of the sliding strip 18 and the support member 20, so that the support members 20 are flush with the upper edges of the guide rails 44 at level 16.
  • Each support member 20 has two rollers 46 on the end face, each of which engages under the upper leg of the guide rail 44. These rollers 46 are rotatable on axes which are fastened in plastic plugs 48 which are inserted into the support members 20.
  • the upper horizontal limbs of the guide rails 44 extend beyond the length of the support rails 14 and are continued in curved sheets 50, which are assigned to the quarter-circle deflection zones.
  • a vertical guide 52 in the form of a U-profile, the inside width of which is equal to the diameter of the rollers 46, so that the support link belt is also guided exactly in this vertical path section between the two deflection zones.
  • the motor 42 is started and the upper part of the supporting link belt 24 slides on the sliding strip 18 with little friction and quietly in the direction of the chain wheels 36.
  • the lower end of the supporting link belt 24 enters the lower arch guides 50, is deflected and gets into the lower guide rails 44.
  • the rollers 46 overlap the lower leg of the guide rails 44 and roll on this leg with low friction. Should the sliding resistance increase for any reason, the upper leg of the U-för- Migen guide rail 44 that the pushed strand of the support link belt 24 can not flare up. In the reverse drive direction, the entire belt run below the driven chain wheels 36 is pulled. The frictional forces are low because the rollers 46 exclude larger sliding resistances.
  • the upper band strand is thanks to the upper B ogenbleche clean 50 inserted into the upper guide rail 44th
  • a modification is that the lower sprockets 38 are omitted, the lower arch plate 50 is assigned a concentric inner arch plate at a distance equal to the clear distance of the vertical guide 52, so that the rollers 46 guide the link belt 24 in the deflection area.
  • FIGS. 5 and 6 differs from the previous figures only in that two further chain wheels 54 are fastened on each of the two shafts 32, 34 and are looped around by an endless chain 56.
  • the two sprocket pairs 36, 38 are synchronized in this way. The hanging part of the support link belt 24 is thus relieved when pushing.
  • the guide rails 45 consist of mirror-image Z-profiles, the upper horizontal leg being offset somewhat downwards from the upper edge of the vertical leg.
  • plastic end plugs 58 are inserted, which have a continuous slot 60 running in the longitudinal direction of the support member belt, into which the horizontal guide leg 62 of the guide rail 45 engages with all-round play.
  • the B in turn join ogenbleche 50, which are in turn connected by a leg of the vertical guide 52 which is here shown as L-profile.
  • the joints 28 of the chain links 26 are located in the middle of the width of the support links 20, making it possible to run the two upper arch plates 50 concentrically with the drive shaft 32.
  • the sections 64 of the end plugs 58 which engage under the guide limbs 62 of the upper guide rails 45 have circularly curved surfaces which lie symmetrically to the center of the width of each support member 20. The radius of curvature corresponds approximately to that of the sheet metal 50, so that the support members are guided exactly.
  • the upper guide rails 45 in turn serve exclusively as an auxiliary guide when pushing the supporting link belt in order to limit lifting off from the sliding strips 18. Lower deflection sprockets are not required in this version.
  • the support members 20 are supported in a line-like manner with the convex surfaces of the sections 64 of the end plugs 58 which overlap the rail guide legs 62 here, so that only narrow contact zones with low friction resistances are formed.
  • FIG. 9 shows a cross section similar to that of FIG. 8.
  • the support members 20 are longer here and extend almost to the vertical leg of the guide rails 45.
  • Each support member has at its end a slot 61 running in the longitudinal direction of the support member belt, into which a plastic end piece 59 is inserted, which closes the end face of the support member 20 and the one channel corresponding to the slot 60 according to FIG. 4 for receiving the guide leg 62 of the guide rail 45 having.
