Abstract
Description
- The present invention relates to a mast system for constructing a mast, comprising:
- a) a number of stackable mast parts which are releasably connectable to each other in order to form the mast;
- b) a lifting device arranged on a frame which is mountable round the mast, which lifting device comprises a first arm provided with a first winch;
- c) means for displacing the frame in longitudinal direction of the mast to the upper mast part; and
- d) means for locking the frame to the upper mast part;
- 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. There is little space on a fairground so that a high-capacity lifting crane which can displace the mast parts to great height over a great distance must be utilized for the purpose of constructing high masts. Such cranes are expensive and must be reserved in good time by fairground operators. The mast system according to the invention therefore saves costs and increases flexibility.
- In a first preferred embodiment the drive of 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.
- According to a further preferred embodiment of the mast system according to the invention, 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.
- According to a practical preferred embodiment, the means for displacing and/or locking the frame are configured for co-action with uprights of the mast parts.
- According to a further development of this practical preferred embodiment, 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.
- According to another preferred embodiment, 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:
- a) positioning a first mast part on a ground surface;
- b) mounting the frame on the first mast part;
- c) displacing the frame in longitudinal direction of the mast to the upper mast part;
- d) locking the frame to the upper mast part;
- e) pivoting the arms to the starting position;
- f) coupling a subsequent mast part to the winches;
- g) lifting the subsequent mast part to the lifting position using the winches;
- h) positioning the subsequent mast part in line with the mast by pivoting the arms to the end position;
- i) paying out the subsequent mast part with the winches;
- j) uncoupling the subsequent mast part from the winches;
- k) locking the subsequent mast part to the adjacent mast part; and
- l) repeating steps c) to k) until the mast has reached a predetermined height.
- The invention will now be described in more detail with reference to the figures.
