Definitions

  • the invention relates to a tilting mast with a stationary mountable mast shoe and a tiltable mast mounted thereon with a lower mast foot part and an upper mast tube part, and a double-acting hydraulic piston-cylinder unit, which on the one hand on the mast shoe below the tilting bearing point and on the other hand off-center on the tilting mast, in particular on the mast tube part of which is articulated above the tilting bearing point, the mast shoe being a tube or box body which is essentially closed in cross section and the mast base part is a tube or box body which is open on one side in cross section, which encloses the mast shoe in an upright position and one which can be closed with a detachable cover Has hand hole, as well as with a locking mechanism for connecting the mast shoe and mast base part when the mast is upright.
  • Such tilting mast constructions are provided for applications in which the masts exceed a size that still allows manual laying and erection of the masts.
  • such constructions are necessary for masts that carry a top load, for example lighting devices that also have to be serviced regularly.
  • a tilting mast of the type mentioned in which the unlocking and locking of the mast by vertical
  • An lifting and lowering of the mast tube part or the post upper part takes place by means of a cylinder-piston unit in an elongated hole guide of the mast foot part or the base part.
  • the upper part of the post comes out of the effective range of a retaining pawl, so that it could in principle be tilted with the pivot point in the slot guide.
  • the effect of the piston-cylinder unit acted upon in the sense of an extension, by means of which the mast is raised for unlocking is precisely opposed to such a tilting movement.
  • an auxiliary piston-cylinder unit must therefore be provided, which is used to tip over the post upper part when it is raised by the pressurized main piston-cylinder unit or an additional holding device for the mast be present in the raised position in the slot, after which the piston-cylinder unit can be relieved of pressure.
  • the mechanical holding device would have to be very large, since it has to absorb the entire weight of the mast. For operation, it is also the case that there is a possibility of errors if the correct sequence of control, reversing and locking processes is not observed. Falling back of the upper post part in the slot guide in the event of incorrect control or incorrect operation can lead to damage to the mast or to the lighting device carried by it.
  • the present invention has for its object to provide a tilting mast structure that is simplified in both the structure and in the control of the actuators, in particular the initiation of the tilting process should be facilitated without the risk that this is done unauthorized or unintentional .
  • the mast shoe has in its interior a spring element adjustable holding element in the form of a displaceable bolt, a pivotable pawl and / or an adjustable cam and on the mast foot part a latching means in the form of an eyelet, a tab provided with a hole or a catch or recess is attached, whereby - with the mast erected - the holding element can be locked with the latching means and the size of the spring force taking into account the translation of the locking mechanism and / or a locking element arranged in the interior of the mast shoe and accessible via the lockable cover of a manual release from outside the tilting mast.
  • the tilting process can be initiated by pressurizing the piston-cylinder unit in the sense of shortening after the locking device secured inside the mast shoe has been released. After releasing the locking device, the mast is in an almost unstable equilibrium, so that an auxiliary piston-cylinder unit or the like can advantageously be dispensed with. Protection against unauthorized access is ensured by the fact that the locking mechanism is located inside the mast shoe designed as a box body and cannot be unlocked manually from the outside.
  • a first further solution consists in that a locking element is arranged on the releasable cover for the hand hole in the mast shoe and a part of the locking mechanism, in particular a hand lever, is secured or blocked in the locking position with the cover closed at the same time and in the opened lid in Unlocking position can be fixed directly or via an attachable extension rod on the mast shoe - in particular by means of a plug pin connection - and prevents the lid to be closed in the area of the locking element.
  • the lid provided with a locking device offers the possibility of securing the locking device against unauthorized access, for example, by providing the lid with a built-in cylinder lock, on the other hand, the locking element provided ensures that the lid is only in the Locking position can be closed and the lid is prevented from closing when the mechanism is unlocked. The respective operator, who will not leave the tilting mast without closing the lid, is therefore forced to operate the locking device properly in the manner of a lock.
  • the cover can furthermore provide access to electrical installations of a light mast arranged inside the mast shoe, so that a dual function is thereby fulfilled.
  • the hand lever of the locking mechanism can be extended tion rod can be connected, which can be fixed in the unlocked position on the mast shoe - in particular by means of a plug-in pin connection. This allows the operator to concentrate on laying the mast and is not forced to hold the locking mechanism against the action of the spring force during this process.
  • the second further solution consists in that the mast shoe in the area of the lower fixed articulation point, in particular in the form of a bearing bracket, for the piston-cylinder unit has an opening through which a vertically actuable lever end of an actuating lever of the locking mechanism passes, so that at the lever end the lower end of the piston-cylinder unit - in particular by means of a plug-in connection through an eye hole - can be articulated in a movable point of application, that in the locked position the point of application at the lever end lies above the lower fixed articulation point for the piston-cylinder unit and that in the unlocked position the lever end can be fixed together with the lower end of the piston-cylinder unit at the fixed lower articulation point - in particular by means of a plug-in pin connection through congruent eye holes. (Figs. 2 and 3)
  • This preferred embodiment is actuated in such a way that the piston-cylinder unit is articulated at the end of the actuating lever, which should not be adjustable manually or by body weight due to the selected transmission ratio, after which the piston-cylinder unit is extended is applied and releases the locking mechanism.
  • the piston-cylinder unit which is supported against the floor or the foundation, prevents the mast from overturning.
  • the lower articulation point of the piston-cylinder unit is now at the same time fixed at the fixed lower articulation point - in particular with the same push-through connection as between the piston-cylinder unit and the actuating lever - after which the piston-cylinder unit is reversed and pressurized in order to shorten it becomes.
  • the mast is tilted over and its controlled turning over takes place. Since unlocking is only possible with the aid of the piston-cylinder unit and is locked again immediately when reversing without establishing the additional plug-in connection, in the embodiment described here, the mast can only be tilted when the piston-cylinder unit is fitted as specified. This provides increased security against any incorrect operation.
  • the locking device can be characterized in that - with the mast erected - an eyelet or tab on the made-to-measure foot part passes through an opening in the mast shoe and is held by a bolt or a latch for locking the erected mast.
  • This configuration is particularly advantageous when the locking device, as described above, comprises a simple hand lever and a cover provided with a locking element.
  • a combination with a lever end protruding from the mast shoe, as also described above, is also possible via a linkage, the piston-cylinder unit being articulated at the lever end to unlock the mast.
  • the locking device can be characterized in that - when the mast is erected - a horizontal to the actuating lever horizontally Arranged locking bolt passes through elongated holes in the lower part of the mast shoe and engages with its ends in bulges on the lower lateral edges of the mast foot part to lock the erected mast.
  • the actuating lever can be designed as a one-armed lever, which simplifies the construction, since intermediate links and transmission links can be completely eliminated.
  • the actuating lever should not be able to be actuated manually from the outside by the selected spring force or the selected transmission ratio, it is provided in a preferred further development that the locking mechanism, in particular the bolt or the lever, is directly or indirectly, in particular on, the spring leading and the spring force transmitting rod can be fixed by a locking pin inside the mast shoe to lock the erected mast. In conjunction with a lockable cover in the mast shoe, this further increases the security against unauthorized unlocking of the mast.
  • the upper articulation point for the piston-cylinder unit is - when the mast is erected - preferably arranged off-center on the mast tube part vertically above the lower articulation point, whereby the corresponding bearing eye can be provided on a collar welded like a pipe clamp or a bolt inserted through the tube.
  • tilting can be initiated manually and thus transferred to a single-acting piston-cylinder unit.
  • the piston-cylinder unit is - as is known in the prior art - designed as a transportable unit, which can be attached to the tilting mast as required and via an independent pressure generation system, in particular with a hand pump, and via its own control systems for reversing between extension and shortening, and in particular is provided with throttle elements to control the tilting speed of the mast.
  • the tilting mast is erected and locked in the left half of the picture, unlocked in each case in the right half of the picture and shown laid horizontally.
  • the construction has a box-shaped mast shoe 1 with a generally square cross section, the base plate 24 of which can be screwed onto a foundation in a stationary manner.
  • the mast shoe 1 which is provided with an upper slope 25, there is a tilting mast 2 in a tilting bearing point 6 stored, which comprises a mast base part 3 and a mast tube part 4.
  • the mast foot part 3 of the tilting mast 2 encompasses the mast shoe 1 in an upright position, its basic shape being a box open at the bottom and on one side.
  • the bevel 25 on the mast shoe 1 enables the pivoting movement of the cover plate 26 of the mast foot part 3 about the tilting bearing point 6.
  • the upper mast tube part 4 of generally round cross section is placed on the cover plate 26, with gusset plates 27 being provided for reinforcement.
  • an eye bearing block 15 is provided, to which a hydraulic piston-cylinder unit 5 can be linked with the lower end.
  • the upper end of the piston-cylinder unit 5 can be articulated in a bearing block 29 which is formed at the end of a bolt or a clamp band 23 in the area of the mast tube part 4.
  • the piston-cylinder unit 5, the control means and pressure generating means are not shown, is reversible and can be lengthened and shortened under load.
  • a vertically protruding tab 9 with a hole is provided in the interior of the mast foot part 3, which passes through an opening 10 in the mast shoe 1 when the mast is erected.
  • a bolt 8 is provided in the mast shoe 1, which is vertically displaceable against the force of a spring 28. The latch 8 can be inserted into the tab 9 and locks the tilting mast 2 by resting on the inner wall of the mast shoe 1.
  • a two-armed hand lever 14 is arranged on the bolt 8, which blocks in the locked position by a locking element 13 inside a releasable cover 12 becomes.
  • the hand lever 14 can be pressed down in particular by means of an extension rod 20, as a result of which the bolt 8 is pulled out of the tab 9.
  • the extension rod 20 can be fixed on the mast shoe 1 by means of a plug-in pin connection.
  • a one-armed lever 30 is arranged on the bolt 8, which can be adjusted via a handlebar 31 by the operating lever 32.
  • the two-armed actuating lever 32 mounted on an axis of rotation 22, the lever end 17 of which passes through an opening 16 in the mast shoe 1, has an outside eye hole 19 to which the piston-cylinder unit 5 can be articulated.
  • the lever 32 is moved clockwise, whereby the mast is unlocked.
  • an operating lever 36 is mounted inside the mast shoe 1 on an axis of rotation 35 and passes with the lever end 17 through an opening 16 in the mast shoe 1.
  • the cranked lever end 17 has an upper eye hole 19 for articulating the lower end of the piston-cylinder unit 5 and a lower eye hole 37 that is located in the locking position above the eye hole 18 in the eye bracket 15.
  • a vertically arranged, horizontally arranged locking pin 38 is fastened to the actuating lever 36 and passes through elongated holes 39 in the mast shoe 1 on both sides. This locking pin 38 engages in the locking position in recesses 40 on the lower edge of the mast foot part 3, which extends at a distance from the base plate 24, and in this way locks the mast in an upright position.
  • a rod 41 is articulated on the actuating lever 36, via which the force of a spring 28 is transmitted to the actuating lever 36 in the sense of holding it up.
  • the rod 41 can be locked with a securing bolt 42.
  • the actuating lever 36 can be pressed downward against the force of the spring 28 by pressurizing the piston-cylinder unit 5, as a result of which the locking pin 38 comes out of the region of the recess 40, as a result of which the tilting mast 2 is unlocked.
  • the unlocking position of the locking pin 38 can be secured and at the same time a fixed articulation point for the lower end of the piston-cylinder unit 5 can be established that tilting of the mast can be initiated by pressurization in the sense of shortening the piston-cylinder unit 5.
  • the tab 9 can be replaced by a pivotable pawl. This is then pivotally arranged on the mast foot part 3 and loaded by a spring. At the Erecting the mast, the pawl is moved through the opening 10 and rests with a hook part on the inner wall of the mast shoe part 1, whereby the mast shoe and mast foot part are locked together.
