Definitions

  • the present invention relates to a mast system for constructing a mast, comprising:
  • Such a mast system is known from the Chinese utility model CN 202670977 U .
  • the known mast system is part of a lift which is self-erecting and intended for use on a building site.
  • This lift can be erected to a great height and serves to replace a tower crane for lifting light materials for finishing buildings.
  • the deployment of a tower crane in the finishing of buildings can be avoided through use of this lift with the known mast system and the associated costs can be saved.
  • the known mast system has a number of drawbacks.
  • the most significant drawback is that moving of the mast part for stacking to an aligned position lying in line with the mast has to be performed by manual rotation of the arm about the longitudinal axis thereof.
  • the raised mast part moreover has to be aligned manually from the lifting position relative to the mast. Locking and unlocking of the frame has to take place using an operating handle.
  • the winch is likewise manually operated.
  • the present invention has for its object to improve and make the known mast system suitable for other applications, for instance the construction of a mast for an amusement attraction.
  • the mast system according to the present invention has for this purpose the feature that the lifting device comprises a second arm provided with a second winch for lifting together with the first winch the mast part for stacking to the lifting position, that the arms are mounted pivotally on the frame and that each arm is provided with an individual drive, and that the lifting device is configured to move the mast part for stacking from the lifting position to the aligned position by pivoting the arms.
  • the pivotable lifting device enables a rapid positioning of the mast part for stacking on the mast. From the aligned position the stacking can be completed by paying out the winches.
  • the separate operation of the drives of the arms makes it possible to carry the mast part for stacking into an optimally aligned position in line with the mast. Operation takes place by means of a controllable drive of the lifting device, which further increases speed and accuracy.
  • the dual embodiment of the arms moreover provides a strong construction with optimal safety.
  • the mast system according to the invention is very compact, this being a particularly great advantage in the construction of a mast for mobile applications such as a fairground attraction.
  • each arm comprises a hydraulic cylinder which is connected to the frame and configured to move the arm.
  • the choice of hydraulic cylinders contributes toward making accurate and reliable corrections to the aligned position.
  • An imaginary line through pivot points of the arms preferably lies out of the centre of the frame so that space is available on the frame for the hydraulic cylinders.
  • each arm comprises two arm parts of differing length which make an angle with each other, wherein the shorter arm part is provided at an outer end with a pivot point for mounting on the frame.
  • the bent arms guarantee an unimpeded movement of the cable along the cable pulley of the winch in all positions of the arms.
  • the means for displacing and/or locking the frame are configured for co-action with uprights of the mast parts.
  • the mast parts and the frame have a substantially square cross-section and the plane of the frame is rotated through an angle of substantially 45 degrees relative to the plane of the mast.
  • the displacing means and/or locking means can now be mounted halfway along the sides of the square frame for co-action with the uprights in order to thus form a stable construction.
  • the frame is provided with a work platform for personnel. It is usual in the field for adjacent mast parts to be stacked and locked by personnel who climb up the mast. In the mast system according to the invention personnel can make use of the work platform so as to thus further increase the speed of construction of the mast.
  • the present invention also relates to an attraction for amusement rides, such as a fairground attraction, comprising a mast system according to the invention.
  • the invention also relates to a method for constructing a mast, for instance a mast for an amusement attraction, using a mast system according to the invention, comprising the following steps of:
  • FIGS. 1 to 6 illustrate a mast constructed by means of the mast system according to the present invention at different stages.
  • Mast system 1 is illustrated in a preferred embodiment in which the mast is part of an attraction for amusement rides, in this case a fairground attraction.
  • the mast is constructed from mast parts 2 with a lattice frame provided with four substantially parallel uprights 22.
  • the mast has a generally square cross-section. This form can of course also be different, for instance round or rectangular.
  • Mast parts 2 are stackable and are provided for this purpose with coupling means 26. These coupling means are located at an outer end of uprights 22 of each mast part 2. Located at the other outer end of uprights 22 are co-acting coupling means (not shown) for receiving the protruding coupling means 26.
  • the coupling means provide for a releasable coupling.
  • Stacked mast parts 2 will be referred to in this text as "mast”. This mast has a variable height. Stacked mast parts 2 can be locked to each other. Such masts are known in the relevant field, as are suitable locking means therefor.
  • Mast system 1 comprises a frame 6 which is mountable round mast parts 2.
  • Frame 6 is provided with a lifting device for lifting mast parts 2.
  • Frame 6 is displaceable in longitudinal direction of mast parts 2.
  • Frame 6 is lockable at a desired height to each mast part 2. This locking preferably takes place on the upper side of the uppermost mast part of the mast.
  • the lifting device according to the invention comprises two arms 8. Each arm 8 is provided with a winch 10 with a cable 14 which is trained along an outer end of each arm 8, for instance by means of a cable pulley 12. Located at the other outer end of each arm is a pivot point S for mounting of the arm on frame 6.
  • the lifting device according to the invention is configured to pivot a raised mast part 2 from a lifting position to an aligned position from which it can be stacked on the mast.
  • each arm 8 is individually drivable.
  • Each arm 8 is connected for this purpose to a hydraulic cylinder 9.
  • the hydraulic cylinders are also mounted on frame 6.
  • each arm 8 takes a bent form.
  • Each arm 8 comprises two arm parts 8A, 8B which make an angle with each other.
  • the shorter arm part 8B is provided with the pivot point S and is connected to hydraulic cylinder 9.
  • arms 8 are mounted on either side of frame 6.
  • An imaginary line L through the pivot points S lies out of the centre of frame 6.
  • frame 6 likewise has a generally square cross-section and is constructed from four beams 7.
  • the pivot points S of each arm 8 are mounted out of the centre of two of the beams 7.
  • the arms can alternatively take a straight form.
  • Arms 8 preferably take an identical form.
  • Arms 8 are pivotable between a lifting position, in which arms 8 incline forward toward the mast part 2 for lifting. This lifting position is illustrated in figure 2 . Arms 8 are also pivotable to a rest position in which both arms 8 extend substantially in longitudinal direction of the mast. This rest position is illustrated in figure 1 as starting position and in figure 6 as end position.
  • the lifting device can also take up diverse aligning positions. Using the individual drives 9 both arms 8 can take up different positions for the purpose of aligning the mast part 2 for stacking on the mast. A possible aligning position is illustrated in figure 4 .
  • Frame 6 is arranged round mast 2 such that the plane of frame 6 is rotated through an angle A about the longitudinal axis of the mast relative to the plane of the mast. Angle A is substantially 45 degrees.
  • Frame 6 has to have a cross-section shaped in accordance with the cross-section of the mast parts. In this preferred embodiment this is a generally square cross-section.
  • the cross-section of the frame can however also take other forms, for instance round.
  • Frame 6 is provided with rolling elements, in this example wheels 16, which are arranged on beams 7 and/or on sub-beams 17. Wheels 16 roll along uprights 22 of mast parts 2. Frame 6 is further provided with a suitable drive for displacement along the mast in longitudinal direction of the mast.
  • the other two uprights 22 which do not guide wheels 16 of frame 6 are configured for co-action with locking means.
  • these locking means comprise claw brakes 18.
  • Uprights 22 are provided with profiles 24, for instance T-profiles, co-acting with claw brakes 18.
  • suitable locking means for instance pin-hole connections of jack-up systems.
  • the drive for frame 6 preferably takes a hydraulic form, for instance with hydraulic cylinders 15.
  • the means for displacing the frame and the means for locking the frame are preferably integrated.
  • Hydraulic cylinders 15 can be provided for this purpose with the claw brakes 18, whereby frame 6 can also ascend and descend along the mast.
  • frame 6 is further provided with a work platform 19 which is accessible by personnel.
  • a control for operating the diverse (hydraulic) drives is preferably arranged on work platform 19.
  • Frame 6 with work platform 19 will of course be embodied completely in accordance with current safety standards.
  • Work platform 19 will be provided with a rail (not shown) and personnel have to be secured when working on the work platform. The presence of personnel is necessary for the purpose of locking the stacked mast parts 2 to each other and for coupling and uncoupling the cables 14 to and from each mast part 2.
  • Figure 1 illustrates positioning of a mast part 2 for stacking adjacently of a partially erected mast. Displacement of the frame in longitudinal direction of the mast to the uppermost mast part and locking of frame 6 to the uppermost mast part have taken place and arms 8 are in the rest position.
  • Figure 4 illustrates positioning of the mast part 2 for stacking in line with the mast by pivoting the arms to the end position or rest position. If necessary, the position of the mast part can be corrected visually by hand by individual operation of drives 9 of arms 8.
  • the frame can remain in place at the top of the mast and the attraction can be constructed on the mast.
  • the mast system according to the invention is also suitable for dismantling of the mast.
  • the arms pivot backwards and during disassembly the arms pivot forward.
  • the above described steps have to be performed in reverse sequence during disassembly.
  • the mast parts are then removed one by one, starting from the situation shown in figure 6 and ending at the situation shown in figure 1 .
