Definitions

  • the present invention relates to a device for carrying out operations at locations difficult to access, such as at great heights, comprising a basket and a connecting piece.
  • Such baskets are generally known and are for instance used in aerial devices, telescopic handlers, cranes, etc.
  • a drawback of the known baskets is that they are generally quite small and that the permitted load and the number of persons allowed in the basket are generally relatively low.
  • European Patent Application EP1775255 discloses an extendible hoist platform, whereas United States Patent Application Publication US 2002/0144862 discloses apparatus for monitoring loading of a lift.
  • the invention has for its object to propose a device with improved properties according to claim 1.
  • the invention is distinguished for this purpose in that the basket comprises a first platform with first railing structures, at least one second platform with second railing structures and adjustable connecting means between the first platform and each second platform, this such that each second platform forms an extension of the first platform.
  • a multifunctional basket is in this way obtained with an adjustable width.
  • adjustable connecting means must be interpreted broadly in the sense that the overall width of the basket can for instance be adjustable in stepwise or continuous manner, or that the width can for instance have only two values. Telescopic connecting means can for instance thus be provided which allow a large number of variable widths. According to another embodiment however, hinges can also be provided between the first platform and each second platform, wherein each second platform is movable between a folded-in and a folded-out position, such that two or more different overall widths are possible in accordance with the number of second platforms.
  • the dimensions of the basket are preferably further chosen such that the basket is easily transportable in the position with minimal width.
  • the at least one second platform consists of two side platforms on either end of the first platform.
  • the first platform preferably has an elongate form with a length greater than 5 metres, still more preferably greater than 6 metres and for instance about 7 metres.
  • the side platforms preferably have a length roughly equal to half the length of the first platform or slightly smaller than said half.
  • the first elongate platform comprises a first railing structure on each longitudinal side of the platform.
  • Each first railing structure is preferably provided with a plurality of vertical uprights, for instance at least five uprights, and a plurality of horizontal girders. Diagonal elements are preferably further provided between adjacent vertical uprights to enable better take-up and transfer of loads on the side platforms.
  • the invention relates to a connecting piece for pivotally connecting a loadable platform to a machine, preferably for connecting a basket to a device for carrying out operations at locations difficult to access, comprising:
  • the measuring means are preferably adapted to measure the bending in different directions. This has the advantage that an overload in a determined direction can be detected.
  • An embodiment relates to a connecting piece for pivotally connecting a loadable platform to a machine, preferably for connecting a basket to a device for carrying out operations at locations difficult to access, comprising:
  • Such a construction has the advantage of being very rigid, simple and compact compared to existing connecting pieces.
  • cylinders for actuating the pivoting are mounted in the second tubular body.
  • the second tubular body can further be provided with a support platform for an auxiliary tool.
  • the connecting piece for pivotally connecting a loadable platform to a machine comprises:
  • FIG. 1 illustrates a connecting piece 2 which can be embodied in random manner and to which is attached a basket 1 according to an embodiment of the invention.
  • Connecting piece 2 is intended for connection to an optionally mobile device, such as for instance an aerial device, a telescopic handler, a device with a jib, a forklift truck etc.
  • connecting piece 2 is provided with a platform on which an auxiliary crane 20 is mounted, although the skilled person will appreciate that this is an option which can be omitted.
  • one or more modified connecting pieces will typically be provided.
  • the basket will typically be connected on its underside to the scissor arm.
  • Basket 1 is constructed according to a possible embodiment of the invention. Basket 1 comprises an elongate central work platform 3 and two side platforms 4, 4' extending on either end of elongate central platform 3 in line therewith.
  • Central platform 3 has a bottom 10 and two substantially parallel railing structures 5a, 5b.
  • Each side platform 4 has a bottom 11, two parallel railing structures 6a, 6b and a closure 7 at the outer end furthest removed from the central platform.
  • Closure 7 can for instance be embodied as a double-security door, such that two operations are necessary to open such a door.
  • the door can for instance thus be connected hingedly on one side to railing structure 5a, and a spring bolt can for instance be provided on the other side between door and railing structure 5b, in combination with a hook/flange system, such that the spring bolt must be released on the one hand and the door must be lifted and opened on the other in order to open the door.
  • the door can further be provided with a detection system which detects whether the door is open or closed. Loads can be loaded onto the work platform from the side in simple manner by providing such doors.
  • anchoring points 8 for anchoring a load in the basket.
  • Such anchoring points can of course also be provided at other locations.
  • the basket is preferably manufactured from very high-grade light materials, wherein specially rolled lightweight profiles with a high moment of inertia are for instance used, this such that the dead weight is very low in relation to the permitted load.
  • the materials suitable for the basket are, among others, high-strength types of steel, aluminium, particularly the aluminium alloys typically used in aircraft, strong plastics, composite materials etc.
  • side platforms 4, 4' are mounted telescopically relative to central platform 3.
  • the longitudinal sides of central platform 3 are more particularly provided with U-profiles 12a, 12b, in which sides 13a, 13b of a side platform 4 can be guided, see figure 2 .
  • These sides 13a, 13b are formed here as tubular profiles with a height adapted to that of the U-profiles.
  • side platforms 4, 4' can be connected in fold-out manner relative to central platform 3, wherein side platforms 4, 4' can for instance be folded out from a vertical position to a horizontal operating position.
  • side platforms 104, 104' are movable from a folded-in position, in which the side platforms are situated on central work platform 103, to a folded-out position in which the side platforms lie in line with central work platform 103.
  • a set of pivotally mounted support arms 105a, 105b; 105a' , 105b' are provided for each side platform 104, 104' (only 105a and 105a' are shown in the figure, although arms 105b, 105b' are provided in similar manner on the other side of the side platforms).
  • These support arms perform a circular sideward movement in order to move side platforms 104, 104' from the folded-in position to the folded-out position, see figures 5A-C .
  • bottom 10 of the central platform has a length l c , for instance 7 metres, and a depth d
  • the side platforms have a bottom 11 with a length l z which is substantially equal to half the length l c .
  • the maximum length is equal to twice the length of the central platform minus the minimum overlap (2*l z ) between the central platform and the side platforms.
  • the maximum length can for instance be 13 metres.
  • the dimensions, and particularly the length and depth dimensions can be adapted in accordance with the needs of the user and/or in accordance with the application.
  • connection between the railing structures of central platform 3 and side platforms 4, 4' typically takes place using an end of stroke safety 9a, 9b such as two hooks which mutually engage, optionally in combination with a locking or overlapping latches.
  • end of stroke safety 9a, 9b such as two hooks which mutually engage, optionally in combination with a locking or overlapping latches.
  • the connection between bottoms 10, 11 can for instance take place in similar manner.
  • side platforms 4, 4' can be locked in different, non-fully extended positions 3 relative to the central platform.
  • the underside of the bottom of central platform 3 can be further reinforced using stiffening ribs 15, 16, see figures 1 and 3 .
  • stiffening ribs 15, 16, see figures 1 and 3 can be arranged to greater or lesser extent in determined positions or according to a determined pattern, such as in a honeycomb structure, a diagonal structure, a lateral structure etc.
  • Figure 3 shows a rear view of the basket of figure 1 . Particularly shown herein is connecting piece 2 between basket 1 and a random machine (not shown), this connecting piece being shown in further detail in figure 4 .
  • connection consists of a supporting tube construction 2 which allows pivoting of the basket through 180 degrees.
  • a construction can be provided which allows pivoting of 0 to 360 degrees or 360 degree continuous pivoting.
  • An overload detection system can further be built in, which is able to detect an overload in the different directions (frontal, left/right).
  • Railing structure 5b is reinforced with elements 17, 18, 19 on the side with supporting tube construction 2.
  • a frame 21 and two mounting profiles 22, 23 are further provided for mounting of connecting piece 2.
  • a rod 25 of rectangular cross-section is mounted between mounting profiles 22, 23 using upper (not shown) and lower clamping blocks 38, 39, between which respectively an upper and lower end of rod 25 is clampingly received.
  • rod 25 can also have an overload detection function in the shown embodiment.
  • rod 25 can be provided with one or more strain gauges, i.e. gauges whose resistance changes when they are deformed. When the rod bends as a result of loads in the basket, this bending can thus be measured. Holes with screw thread can be provided in rod 25 for mounting of the strain gauges. According to an advantageous embodiment as shown in figure 6 , three strain gauges are mounted on rod 25:
  • the bending of the rod can in this way be measured in different directions: frontal, left and right.
