Definitions

  • the present invention relates to tower cranes, in particular those tower cranes in which the crane operator, also referred to as crane operator, sitting in a cabin, which is located on top of the tower tower tip, and operated from there the crane. More particularly, the present invention relates to a transfer for an elevator, in particular for a passenger elevator, more precisely a crane operator lift, according to the preamble of claim 1.
  • Crane driver lifts also known as crane operator lifts
  • crane operator lifts are attached to the crane mast so that a crane driver can more conveniently reach the cabin located at the top of the crane mast, also referred to as crane tower.
  • a crane driver can more conveniently reach the cabin located at the top of the crane mast, also referred to as crane tower.
  • the transport of the crane operator and the transport of material is thus possible, for example, for assembly and repair activities on the crane.
  • Object of the present invention is therefore to provide a transition for an elevator, which is attachable to a crane mast and which is protected in the assembled state from damage, especially when the crane on the the transfer is attached, disassembled and the individual mast segments of the crane are transported.
  • the crossing according to the invention is intended for use in a crane, in particular a tower crane. He creates a transition for the crane driver or for any other person who wants to get in and out on a crane mast, in particular on the outside of the crane mast, attached elevator. Due to safety regulations, a so-called transition between the crane mast interior and the elevator, more precisely the elevator car or the elevator platform, is to be provided for this purpose.
  • the crossing according to the invention has at least one fastening means with which the passage on the crane mast, also referred to as crane tower, can be fastened.
  • the attachment is made detachable; solvable insofar as the crossing, after it has been attached to the crane mast, can be solved by this again.
  • Under releasable is understood in the course of the invention that the release of the attachment can be done without destroying the fastener or the passage, not even partially, possibly by destroying an aid for the fastener, such.
  • B. a rivet A separation of the crossing from the crane mast z. B. using an angle grinder is not releasable attachment in the context of this invention.
  • screwing is considered, or even riveting, despite the fact that the rivet - which is considered as an aid to the fastener - can be destroyed when loosening the connection - the transfer itself remains intact.
  • each fastening means has at least one rail and at least one clamping piece. About the clamping piece a connection between the rail and the crane mast can be produced.
  • each fastening means consists of a rail and two clamping pieces. For the functioning of the invention however, one clamping piece per rail is sufficient. Of course, more than two clamping pieces per rail may be present.
  • a component which has an elongated shape As a rail is understood in the context of the present invention, a component which has an elongated shape. Examples are pipes, folded sheets, angle steels, flat iron or profiles of various types, both hollow and solid profiles.
  • clamping piece could also be spoken by clamping means or clamping element. It is a component or an assembly that fixes another component of the fastener, namely the rail, using clamping forces on the crane mast. A clamping piece causes by pressing the rail against a strut of the crane tower that the rail and thus the transfer to the crane mast are held.
  • the crossing has a folding platform.
  • the foldable platform knows at least two states - a raised state, which could also be said that in this state, the platform is collapsed, and a deployed state, which could also be said that the platform is folded in this state.
  • the platform In the unfolded state, the platform provides a walk-in surface, ie the person using the passage can stand on this platform and walk over it. If a plane passed through the fastening means, in particular the clamping piece, preferably by two clamping pieces on a rail, in the mounted state, the platform remains in the folded state completely on one side of this level - it does not pass through this level.
  • the platform Viewed from an inner region of the crane, the platform remains in the folded-up state in front of this plane, also referred to as the fastener plane. In the folded-up state, therefore, no penetration of this level takes place, but the platform remains beyond or on this side, depending on the viewing position, this level. In the unfolded state, however, the platform penetrates this plane. There is thus provided a transition between an interior of the crane mast and the elevator.
  • the crossing on the crane mast is detachable and non-destructive attachable. He can easily be solved, for. B. by opening screw connections. The crossing can be easily transferred in this way, be removed from a crane to another crane, or for storage.
  • the crossing according to the invention preferably solves not only the problem that hitherto known transfers were to be mounted each time and again destructive to disassemble when setting up or dismantling the crane, but also the problem that the transfers were virtually handmade for each individual crane types, ie had to be made individually.
  • the present transfer is very flexible and Can be mounted in the towers of various manufacturers, despite the different design of the struts, which form the crane mast.
  • the rail represents a profile with a large number of possible receiving points.
  • the transition according to the invention can be used for a large number of different crane types, which is not the case in the prior art.
  • the through holes are present at a constant distance in the rail.
  • a distance of 1 mm to 50 mm has been found, particularly favorable a distance of 5 mm to 20 mm, each measured from the outer edge of a through hole to the outer edge of the adjacent through hole.
  • the flexibility of the assembly is further increased by the inventive design of the clamping piece.
  • the clamping piece has an elongated plate with at least two through holes and two matching screws, d. H. through each through hole a screw can be passed.
  • the two through holes are therefore preferably present in the region of the two ends of the elongate plate.
  • a plurality of through-holes is present in the elongate plate, at least at one end, whereby the distance between the two screws to each other, and thus the clamping width, can be varied.
  • the clamping pieces may comprise different widths of the struts.
  • the elongated plate rests on one side of the strut, the two screws each comprise one side this brace and fix on the back of the brace, also referred to as the opposite side, the rail and thus the crossing of the crane tower by passing through the screws through the through holes of the rail and tightening nuts.
  • the elongate plates are mounted on the inside of the crane mast and on the outside of the crane mast are preferably the screw heads of the screws, so that the screwing can take place inside the crane.
  • the passage has a floor safety door.
  • a landing security door is provided.
  • the transfer on the construction site remains in the folded, d. H. in walkable condition. If the elevator car is not present before this crossing, there would be a danger of falling over the crossing. For this reason, this point must be locked with a door, which is done by the floor security door.
  • floor-level security doors are sliding doors and can be pushed aside.
  • the platform preferably remains in front of this level when viewed from the interior of the crane mast in the folded-up state of the transfer according to the invention. In the folded-down state, the platform preferably also penetrates the plane of the floor protection door.
  • the floor safety door is guided in front of the crane mast, ie outside the crane mast. The platform is therefore preferably beyond the area in which the floor safety door runs.
  • the floor safety door is usually dismounted to transport the crossing and reassembled at each construction site again, as they must, as already mentioned, typically run outside the crane tower in order to fulfill their function.
  • the passage comprises a frame.
  • the hinged platform is articulated and it is also the at least one rail, preferably two rails, connected to the Ge Beach.
  • the two rails can be attached to the same side of the frame - considering the platform in the unfolded state as a base of the frame and thus the crossing. Most preferably, however, the two rails are attached to the frame at a corner, d. H. they are on two different sides, these two sides abutting each other. As a result, the transition can be secured in a corner region of the crane mast, whereby one rail can be fastened to one crane mast side and the other rail to the other crane mast side. In this area, the crossing is particularly space-saving and fixed by the over-corner attachment also in its position.
  • the two rails mentioned in the preceding paragraph are preferably vertically aligned, they follow, in other words, the longitudinal extent of the crane tower.
  • the at least one rail can also be oriented horizontally, d. H. follow the trusses of the crane tower.
  • Particularly preferred three rails are provided, two vertically aligned and one horizontally oriented rails.
  • a further preferred embodiment provides that part of the crossing is also a stepladder.
  • the crossing is mounted in an area of a crane segment in which a standing platform is located.
  • a crane mast is composed of individual mast segments. This, z. B. in a crane without crane operator lift or in case of failure, the crane operator does not have to climb the crane mast in one piece from bottom to top or from top to bottom over a ladder, in each crane segment at least one standing platform available, on which the crane driver or the person climbing in the crane mast can make a stop.
  • the transition from the crane mast to the elevator or from the elevator to the crane mast is typically carried out in the area of such platforms.
  • the step ladder is provided.
  • this is mounted on the frame of the crossing, in particular held by two brackets.
  • the step ladder is displaceable within this bracket, so as to be adapted to the respective position of the standing platform of the crane mast.
  • the passage may preferably also have railing elements. It is Z. B. a railing element is provided, which provides a fall protection to the interior of the crane mast, laterally from the platform. Furthermore, one or preferably two railing elements are provided in the area of the floor safety door, d. H. in the transition region between crane mast or crossing and ramp of the elevator car or the elevator car itself, whereby a lateral protection is provided during the transition from the present crossing in the crane tower to the elevator.
  • a recess can be provided laterally in the platform into which a strut of the crane mast, in particular a diagonal of the crane mast, can engage.
  • a unit comprising an elevator and a transfer according to the invention.
  • This lift can be mounted on a crane mast.
  • the elevator has a ramp, which is in particular hinged. This ramp interacts with the platform of the crossing.
  • This transition is preferably continuous, d. H. he has no gaps in which a person could step into and certainly no gaps that would be so large that there would be a danger of falling.
  • FIGS. 1 . 4 to 6 and 10 the transition according to the invention 1 is shown in the unfolded, ie walk-in state.
  • Figures 2 . 3 and 7 to 9 is the crossing 1 in the folded state and thus shown in Kranmastsegmenttransportschreib.
  • the passage 1 comprises a frame 3, on which in the embodiment shown two elongated rails 15A, 15B are attached. It is basically conceivable to attach the crossing 1 via only one rail 15 on the crane, z. B. by being supported on the crane tower by concern. Preferably, however, at least two elongate rails 15 are present. In the particularly preferred embodiment, shown in the figures, a total of three rails are present, the two vertical rails 15 and a horizontal rail 115th
  • the rails 15, 115 are in the present embodiment hollow profiles with a rectangular cross-section.

  • flat iron or folded and folded sheets can be used, for.
  • the two vertical rails 15 are preferably arranged at a corner, ie they are not viewed from the platform 2 on the same side of the platform 2 but on two abutting sides (see. Fig. 1 ).
  • the arrangement over the corner increases the stability of the attachment.
  • the arrangement of the two rails 15 on the same side of the platform 2, preferably on the front side thereof (cf., reference numeral 32), ie the side facing the elevator 50, would also be possible.
  • each vertical rail 15 is fixed with two clamping pieces 17, whereas for a horizontal rail 115 due to their brevity mounting via a clamping piece 117 has been found to be sufficient.
  • the rails 15, 115 could also be referred to as perforated rails. They have a multiplicity of through bores 16, 116, ie holes which pass completely through the rail 15, 115.
  • clamping pieces 17, 117 are provided, two clamping pieces 17 per vertical rail 15 in the illustrated preferred embodiment.
  • the horizontal rail 115 is connected via a clamping piece 117 with the crane mast 55.
  • Each clamping piece 17, 117 has an elongate plate 18, 118, in which at least two through holes 21, 121 per elongated plate 18, 118 are present. At least each end, first end 27 and second end 28 (see FIG. FIG. 2 ), has at least one through hole 21.
  • a plurality of through holes 21, 121 are provided on each elongate plate 18, 118.

It could also over the entire elongated plate 18, 118 away uniformly distributed or unevenly distributed through holes 21, 121 may be present, similar to the through holes 16, 116 are distributed on the rail 15, 115.
  • Part of the clamping jaws 17, 117 are further two screws 19, 119, which are inserted through the elongated plate 18, 118 and in the assembly through the rails 15,115, more precisely whose through holes 16, 116, are inserted, as for example, is clearly visible in FIG. 7 , Out FIG.
  • the clamping pieces 17, 117 are adaptable to different widths of crane struts, for example at the diagonal 58. If the bracing to be clamped is narrower, the screws 19 'are correspondingly inserted into closer through bores 21' of the elongate plate 18 ', as on the clamping piece 17' in FIG. 8 you can see. If, however, a larger clamping width is required, as in the clamping piece 117 in FIG. 8 can be seen, then correspondingly further spaced through holes 121 are used.
  • the installer only needs to decide which of the struts of the crane tower, whether a traverse, a diagonal or a vertical, he wants to use, then using two clamping pieces 17, 117 per rail 15, 115, the rail 15, 115 on the crane mast 55 to fasten, which in turn the frame 3 and thus the entire crossing 1 is attached to the crane mast 55.
  • rails 15, 115 and at least one clamping piece 17, 117 together form the fastening means 5.
  • the crossing 1 shows according to the invention two states. There is a state in which the crossing 1 is accessible. Here the platform 2 is lowered and thus offers a walk-on surface 30 (see. FIG. 1 ). Unlike in the second state, here the surface 30 of the platform 2 is not accessible because the platform 2 is folded up (cf. FIG. 2 ).
  • the platform 2 is hinged to the frame 3, z. B. on a bearing element 12, in this case by a hinge 31st
  • the platform 2 has on its longitudinal sides in each case a side guard 14 in order to avoid the falling of objects.
  • a recess 20 is provided (see, for example, FIG. FIG. 2 ), in which a strut 60, for example the diagonal 58, can be accommodated, as can be seen in FIG FIG. 4 or FIG. 6 ,
  • the front edge 32 of the platform 2 serves as a support surface for the ramp 53 provided by the elevator 50, as in FIG. 10 you can see.
  • the crane operator thus rises above the surface 30 of the platform 2 and the ramp 53 from the crane tower into the elevator car 51.
  • FIGS. 1 to 3 and FIGS. 7 and 8 show, for the sake of simplicity of illustration, a crossing 1 without floor protection door 4.
  • a floor protection door 4 In the assembled state, however, a floor protection door 4 must be provided due to safety regulations (see, for example, US Pat FIGS. 4 to 6 ).
  • the floor safety door 4 With the floor safety door 4, the transition 40, ie the area in which the crane driver changes from crossing 1 into the elevator 50, is secured, so that no one can accidentally crash if and as long as no elevator 50 stops before the crossing 1.
  • the floor safety door 4 is a sliding door as indicated in FIG FIG. 6 by the double arrow P. In the open state, it releases the transition 40 to the elevator 50. In the closed state, the floor safety door 4 extends over the platform 2 to the opposite side to a corresponding stop 41.

  • the railing 8 is intended to prevent lateral crashes in the crane inner region 59. While floor safety door 4 and the railing elements 9 and 10 should be dismantled usually when the crane is dismantled, the railing 8 can be folded away, as well as the clamp for the floor safety door 11 (see. FIG. 1 With FIG. 2 ). Also, the receptacle 13 for the floor safety door 4 and the railing 10 can be folded and thus remain at the crossing 1.
