Definitions

  • the invention relates to a tower crane according to the preamble of claim 1.
  • a top-rotating tower crane of this type which meets the requirements of a quick and easy and space-saving assembly and disassembly and a disassembly into easy-to-transport assembly and transport units, is known from DE-PS 35 10 116.
  • an essential assembly and transport unit consists of a rail piece connected to the rotating platform, on which the trolley and a carriage provided with the fixed point of the lifting rope and the deflection roller for the trolley traveling rope can be moved so that these together with the rotating platform, form an assembly unit that can be transported by road.
  • This way of combining the turntable with the counter jib, the guying jib, the trolley and the head-end station into one assembly and transport unit has proven very successful with smaller cranes.
  • the object of the invention is therefore to provide a tower crane according to the preamble of claim 1, which can be disassembled, quickly and even in confined spaces, street-appropriate assembly and transport units if it is of a larger design.
  • the supporting structure or platform carrying the machine unit can thus only be combined with the trolley, the sheared load hook and the head station to form an assembly unit that can be transported by road.
  • This type of combination enables the formation of a transport unit that does not exceed the weights and dimensions permitted for road transport and assembly.
  • an assembly unit is created which is already stranded and installed in the factory, so that after or during assembly there is no need for complex and cumbersome stranding and installation work.
  • the lifting and trolley ropes are completely reeved in the factory, all limit switches and safety devices, namely the Lift limit switches, the winding limit switch, the trolley travel limit switches and the overload protection devices are preset in the factory.
  • the assembly and transport unit according to the invention can also additionally contain all electrical installations in preassembled form, so that the assembly is also considerably simplified in this respect.
  • the basic supporting frame which can be connected to the upper end of the tower and which is connected to the rotating platform by means of a rotating mechanism provided with the rotating platform, forms an assembly unit with the crane driver's cab hinged to the rotating platform. Since the crane operator's cab is located to the side of the turntable during crane operation, it can be folded in front of the turntable to form a transport unit, whereby the folded-in transport position and the unfolded operating position can be locked by means of appropriate safety bolts.
  • the turntable expediently has, on its side facing the counter jib, upstanding supporting supports, with the upper regions of which the upper straps of the support structure carrying the winches and the lower straps of the trolley boom can be connected.
  • the bearing points of the supporting structure and the trolley bracket only need to be hooked into the corresponding receptacles, so that there is firstly an easy-to-carry out pre-assembly and the further bolting or securing can then be carried out.
  • the towering supports are expediently stiffened by V-shaped supports.
  • the lower chords of the support structure carrying the winches can be bolted to the base frame of the rotating platform.
  • the support structure for the winches expediently exists and the machine unit from a triangular beam assembly with a lower bar of the base beam that can be bolted to the rotating platform.
  • the counter jib can consist of a box section girder, which is to be connected to the base frame of the rotating platform directly or via the lower cross member to the base girder frame of the support structure carrying the winches.
  • the counter jib can also be connectable to the rear end of the supporting structure that carries the winches and the machine unit.
  • the counter jib bracing is expediently articulated on the counter jib in the area of the rear ballasting. In this way, the bending moments acting on the counter jib can be kept small.
  • the bracing of the counter jib consists of a counter jib guy rod, it is provided in a further embodiment of the invention that it can be locked in its mounting position by a mounting bolt.
  • the counter jib rod can then be raised and bolted in its assembly position with the counter jib still lying on the floor, so that difficult assembly work can be omitted with the counter jib raised in its assembly position.
  • the counter jib tensioning rod can expediently be bolted to the machine cantilevered tip of the triangular beam assembly.
  • the guy bracket which is articulated at the boom articulation point, has an articulated rear holding rod and the guy bracket with a Swing-out support is provided, which fixes the mounting position of the handrail.
  • This configuration also makes it possible to set and fix the angle corresponding to the mounting position between the guy stand and the rear support rod on the ground.
  • the guy stand is also expediently connected to the upper boom of the trolley jib after erection and is thus held in the appropriate mounting position.
  • the guy stand is raised, the boom support linkage is unfolded and held in the correct assembly or functional position.
  • the trolleys of the trolley are mounted on trolley carriers which are pivotally mounted on the trolley frame and can be bolted to the trolley frame in their pivoted-in driving position. In this way, the trolley can be easily moved into its driving position on the running rail formed by the lower straps of the trolley boom. A laborious postponement, which will often not be possible, is no longer necessary.
  • the head station consists of a sleeve-like part with locking bolts which can be pushed onto a holding part connected to the trolley frame to form the assembly and transport unit and can be inserted into a pocket-shaped receiving part at the outer end of the trolley arm and can be locked on this.
  • One side of a catwalk is expediently connected to the triangular structure and the other side of the catwalk is connected to the counter jib. Since the catwalks would widen the construction to an extent permissible for road transport, the triangular structure can be combined with one in this embodiment Place the catwalk and the counter jib with the other side of the catwalk overlapping one another on a transport vehicle in such a way that the permissible width for road transport is maintained.
  • the catwalk located in the area of the revolving platform and leading to the crane driver's cab is expediently foldable onto the catwalk part of the triangular structure.
  • the counterweight plates are provided with lateral locking bolts which are supported on inclined edges by holding plates connected to the counterjib, so that the counterweight plates are self-tensioning.
  • the tower 1 which basically consists of a telescopic tower, is supported on a foundation cross 2 or an undercarriage known as such. With the upper end of the tower 1, the base support frame 3 is connected, to which the rotating platform 5 is connected via the slewing ring 4.

  • the boom is articulated to the coupling pieces 11, 12 of the supports 7, 8 and the guy stand 36 is articulated through the articulation bolts 35.
  • the guy stand 36 can be supported at the fixed point 37 of the upper chord 38 of the trolley boom 39 for mounting so that it does not tip forward before the counter jib guy rod 47 is tensioned.
  • the rear support rod 40 and the front boom guy rod 41 are articulated.
  • the guy bracket 36 is provided in its upper area with a pivotable and in its pivoted position lockable auxiliary support 43 which fixes the rear support rod 40 in the pivoted position shown during assembly.
  • the rear support rod 40 is articulated in the joint 46 to the support tube 20.
  • a further counter jib tension rod 47 is articulated, which with the counter jib 30 in the area approximately through the center of gravity of the counterweight 48 extending line is articulated.
  • the articulated connection located in the area of the counterweight 48 consists of a tab 51 which is articulated to the counter jib by the articulation pin 50 and which can be coupled to the bearing plates by an auxiliary pin 52 for assembly purposes in such a way that the counter jib tensioning rod 47 is held in its assembly position, so that the coupling with the articulated connection of the support tube 20 after lifting the counter jib 30 can be effected without cumbersome manipulations.
  • the counterweight plates 56 are held on the rear crossbeams 55 of the counterjib 30 in the manner shown in FIG. 11 on both sides of the counterjib.
  • the cross members 55 are provided with sheets with oblique sliding planes 57, on which support bolts 58 of the counterweight plates 56 are supported in such a way that they are clamped together under their weight.
  • the trolley 100 consists of a frame 60 in which the deflecting rope pulleys 61, 62 for the lifting rope carrying the crane hook 63 and the bottle 64 are guided in the manner shown in FIG.
  • Lateral supports 65 are articulated to the frame 60 of the trolley and carry the castors 66 at their upper ends.
  • the carriers 65 can be pivoted from a pivoted-out position into a pivoted-in position indicated by dashed lines in FIG. 6 and bolted to the frame 60 in this position. In this swiveled-in position, the castors 66 are located on the lower chords 68 of the boom 39 forming the travel rails.
  • the frame 60 of the trolley 100 is connected to the base support 21 of the support structure for the winches via corresponding holding plates 70, 71.
  • the connection consists of holding bolts reaching into elongated holes 73, so that the undercarriage frame 60 is connected to the supporting structure 13,19 has a certain pivotability.
  • the front end of the chassis frame 60 is connected to a mandrel-like holding device 75, onto which the sleeve-shaped head station 76 is pushed in the assembly and transport position.
  • This sleeve-shaped head station 76 is provided with the fixed point 77 for the hoisting rope 78 and a lateral deflection roller 79 for the trolley rope 80.
  • the head station 76 has been moved forward by the trolley 100 until it snaps into its seat at the front end of the boom, which consists of a pocket-shaped receptacle 82 and a spring-loaded locking lever 83.
  • the catwalk part 86 is connected to the lower area of the support structure 13, 19, 21, which consists of a triangular beam assembly.
  • the opposite catwalk 85 is connected to the counter jib 30.
  • the catwalk part 88 which bridges the rotating platform, is articulated to the catwalk 85 by the articulated connection 87 and can thus be folded onto the catwalk 85 of the counter-jib for transport purposes. Further details of the crane, in particular the individual articulated bolt connections, are not described in more detail because these can be easily understood by the person skilled in the art from the illustration of the drawing.
  • the ropes leading to the trolley winch 15 run over the deflection pulleys 90.91.
  • the hoisting rope 78 is guided over the hoisting rope deflection roller 92 in the rear area of the counter jib so that there is sufficient distance to wind the hoisting rope drum evenly over its width.
  • a transport and assembly unit forms the turntable with a slewing ring support and slewing ring, pantograph, turntable frame with connections for the machine unit and boom, slewing gear and cab.
  • the cab is pivotally connected to the revolving platform for road transport.
  • the cantilever head station with hoist rope fixed point and trolley rope guide pulley, the trolley with load hook, the hoist and trolley chassis with all safety devices and the switchgear are combined to form an assembly and transport unit, in a fully installed, adjusted and stranded form.
  • a holding frame can be provided or the trolley chassis frame can be used.
  • the support structure for the machine unit is only connected to a pedestal on one side.
  • the counter jib essentially consists of a solid wall section beam, which is articulated at the front near the rotating platform to the support structure for the machine unit.
  • the counter jib like the jib, is only simply braced, which means that only one guy rod is provided at a time.
  • the bracing of the counter jib is directed exactly towards the heavy weight of the counterweight arrangement, so that no additional bending moments arise in the solid wall profile beam due to the counterweight arrangement and the articulation of the guy rod. This allows a favorable dimensioning.
  • the counterweights are evenly arranged on both sides of the longitudinal beam of the counterjib and are self-tensioning due to their own weight.
  • the catwalk is attached to the side in the front area of the counter jib.
  • the turntable, machine unit and counter jib can be loaded offset on one vehicle for transport, so that both in the assembled state the permissible transport width is exceeded in accordance with the crane size, but the permissible transport mass can still be maintained during road transport.
  • the electrical installation is hidden at the separation points of the tower and rotating platform on the one hand and the rotating platform and machine unit on the other.
  • the jib and counter jib are therefore without any installation.
  • the revolving platform is first placed on the tower with the cab swung out during operation and connected to it.
  • the supporting structure with the machine unit, the trolley, the load hook and the head station is then hung in a quick-release bearing on the top of the rotating platform and bolted in a tab connection at the bottom. The connection points can be reached safely from the rotating platform.
  • the hoist rope is then unwound somewhat and, after the cable reel bearing has been opened, is inserted into the deflection roller 92 at the rear end of the counter jib 30. Since the assemblies are bolted together to form transport and assembly units, only one assembly stroke is required.
  • the boom 39 is then assembled in a known manner from its individual sections with the associated guy rods.
  • the handrail 40 is opened with the mobile crane and held in its assembly position by means of the pivotable and lockable support 43. This happens while the boom guy stand 36 is still on the boom link. Then the guy stand and the boom guy linkage are erected and brought into the functional position. Here too, the correct mounting position is determined by the support 37.
  • the boom and its holding device are lifted to the rotating platform with the help of a mobile crane and hooked into a quick-release connection here. Now the boom is inclined so far that the trolley roller carrier 65 with its rollers 66 over the lower belts 68, which form the running rails, pivoted and bolted in their operating position to the frame of the trolley or can be locked on this.
  • the boom is raised again to about the horizontal.
  • the bolts that connect the ready-wired assemblies, the trolley, the load hook and the jib head station to the machine unit during transport and assembly can then be removed.
  • the pin bearings are designed as elongated holes, so that no precise boom position must be maintained during this assembly process and damage is avoided when lifting the boom.
  • the load unit which consists of trolley, load hook and jib head station, is manually pushed out over the rotating platform so that the jib can be lowered again and the load unit can roll to the jib tip on the resulting incline.
  • the boom head station is then automatically locked with the boom tip in a manner that is already known per se from DE-PS 35 10 116.
  • the head station is mounted with its hollow body carrier on a carrier arranged at the front of the trolley and is held in this position by the hoisting cable.
