    Telescopic Mast
    FIELD OF THE INVENTION
    The present invention relates to a telescopic mast comprising at least one or more telescopic links with parallel walls, one of two adjacent telescope sections being narrower than the other of the two adjacent telescopic sections so that a telescopic section can be inserted into and out of a the surrounding telescopic section of a telescopic link, as well as the fact that it can be inserted into and out of a further telescopic section of a further telescopic link.
    BACKGROUND OF THE INVENTION
    There are many types of telescope masts, some of which can be extended automatically. In connection with such telescope masts, for example for military use, special requirements are set for usability as well as for operation in extreme situations and weather conditions.
    In addition, demands are made for • low energy consumption, • high load capacity.
    • High telescope speed • Possibility of manual telescoping • That the order of telescoping of the sections can be controlled, for example, that the second-largest mast section telescopes out before the others and as the last • start / stop (mast locked) in all positions, • a design that can protect against rotation of the mast / mast sections about the longitudinal axis (azimuth rotation) • a design that allows internal cabling in the mast up to the payload on the mast • that the mast cannot collapse in single faults which can cause personal injury and / or damage on equipment mounted on the mast and • high load capacity.
    Telescope masts can be very high and can be used for sensors and weapons as well as for pointing targets. High telescopic masts contain many telescope sections. With the above requirements for speed, low energy consumption, it will be appropriate to offset the weight of the load on the mast as well as the individual mast sections.
    Masts are driven pneumatically, hydraulically, electrically as well as manually and in these cases the effect that must be applied to postpone or defer. contraction of the telescopic mast is a result of mast loads, self-weight, friction, etc. and the power consumption for high speed in both directions can be large and the time for manual operation very long as a human can only provide a limited power.
    It is desirable that the telescopic mast's sub-elements are not heavier and larger in scope than is most necessary. In order to live up to the requirements for reliability and robust construction, it is clearly a disadvantage for a telescopic mast if the technique includes fragile technical solutions, which can cause errors that cause the telescopic mast to not be operated quickly, accurately and under all conditions.
    Telescopic masts used in high-load environments are subjected to static as well as dynamic loads. For example, these can be caused by wind loads, as well as dynamic loads that arise from mobile use.
    DK 2018 00189 A1
    These loads can be very large G loads that occur suddenly. This occurs with arbitrary sizes and directions and provides a very complex load picture on the structure.
    These loads can arise from the top where the payload e.g. is mounted and / or from the bottom of the telescopic mast in the case of a mobile base / platform.
    The mast telescope system can / will similarly be subjected to very large loads.
    Therefore, in the case of high telescopic masts, it is highly advantageous if they are made up of simple components that, regardless of conditions, provide a simple and uncomplicated use and operation of the telescopic mast, which minimize maintenance and ensure that the mast can provide high telescopic speeds in both directions combined with positive control of mast length and low power consumption, respectively by manual operation.
    None of the known solutions meet these requirements.
    The object of the invention
    It is the object of the present invention to provide a high capacity telescopic mast (load and mobility), rotation protection and where power consumption is minimized.
    Description of the Invention
    As mentioned initially, the invention relates to a telescopic mast comprising at least one or more parallel wall telescopic poles, one of two adjacent telescopic sections being narrower than the other of the two adjacent telescopic sections, so that a telescopic section can be inserted into and out of the respective telescopes. an adjacent telescopic section of a telescopic link, as well as being capable of being inserted into and out of a further telescopic section of a further telescopic link.
    The telescopic mast is distinguished by the fact that • the mast's drive system is given by lifting strap / wire which is hidden between the sections and thereby can give positive lift as well as contraction and hold / lock the mast in any position. These can be duplicated for safety and reliability reasons. Also, these can be fixed between mast sections so that they are lifted simultaneously or a long tape / wire so that they are not lifted simultaneously.
    • At the same time, resilient elements are arranged between the individual mast sections, inside the mast, so that they equalize the weight of the sum payload and of the sections of the mast which are above the resilient element whereby these are in weight / weight balance. In doing so, the mast drive system alone must overcome frictional forces between the individual mast sections during mast release, respectively. contraction.
    • The mast sections are designed as multilayer pipes, thereby ensuring rotation between the pipes about the longitudinal axis of the mast.
    • Sliding shoes / rails are placed between the low friction mast tubes and minimizing rotation of sections between the mast sections about the mast longitudinal axis. These can be placed only in the bottom of mast pipes adapted to a length that does not exceed the overlap between the mast sections when the mast is fully extended but can also be supplemented with sliding rails inside the top of the individual mast sections.
    Thus, with a telescopic mast according to the invention, a mast with low power consumption can also be obtained at high speed, whether this drive mechanism is manually, hydraulically, pneumatically or electrically driven.
    Thus, single faults on the resilient elements, respectively. drive does not cause a mast collapse.
    DK 2018 00189 A1
    The construction is furthermore advantageous in that the large dynamic forces, shock impacts and G-forces do not have to be absorbed by the drive system to the same extent as in other structures as the resilient elements equalize the basic weight of the structure and the load and at the same time can dampen dynamic influences.
    According to a further embodiment, the telescopic mast according to the invention is characterized in that strips / wires for moving the sections of the telescopic mast are arranged in such a way that they run inside the mast.
    According to a further embodiment, the telescopic mast according to the invention is characterized in that e.g. the resilient element (s) supporting the first telescope section is sized for greater loads than the weight, which will cause the first mast section to move before the other mast sections.
    In practice, it has proved most convenient that the mast is made of angular tubes whereby the guide rail or the guide rails in each telescopic joint can be omitted.

    Detailed description of the invention
    In FIG. 1 -3, different sectional images from the same construction are shown.
    FIG. 1 shows a telescopic mast with five sections 1 showing a section through a single telescopic link 1. The telescopic link 2 comprises a first telescope section 3, a second telescope section 4, a third telescope section 5 and a fourth telescope section 6. The telescope section 3 is of smaller dimension. than the first telescope section 2, so that the second telescope section 2 can be inserted over the first telescope section. It is possible to provide a plurality of telescope sections outside the telescopic link shown, or an additional telescope section located within the telescope link 3 shown.
    In the embodiment shown, the telescopic sections are provided with an angular cross-section, for example, hexagonal (Fig. 3) or orthogonal, etc. Alternatively, the telescope sections may be provided with other cross-sectional shapes, for example circular.
    Located in the free clearance between the sections, there are straps or wires to extend the mast A, respectively, to contract the mast B. These may be a long wire or strap whereby the mast sections move arbitrarily as the drive E rotates. When rotated clockwise F as illustrated, the mast is ejected and when rotated counterclockwise G the mast is pulled together. These wires / straps may also be secured to sections so that all sections guided move simultaneously. If a combination of the above two methods of mast movement is used, some sections can be controlled and others moved arbitrarily. Eg. can be achieved that section 3 always runs out first and last.
    In addition, resilient members C are provided which support the individual sections and by dimensioning these to equalize the load (the weight of sections and loads, etc.). above the resilient element this will equalize this load / weight and thus the drive system must only overcome friction in the mast system by moving the telescopic mast. This allows the mast to be moved with a much reduced energy consumption as this does not have to lift the loads.
    FIG. 2 shows the mast in a contracted condition and here is shown an example of divided slide rails / shoe E. The lower E1 is located at the bottom and outside of the inner telescopic section 3 and slides inside of the outer telescope section 2. The upper slide rail / shoe is placed inside the top of the outer telescope section 2 and sliding externally on the inner telescope section 3.
    As shown in Fig. 3, slides / shoes E (Figs. 3 - F) are fitted. The slide rail / shoe E is mounted on the bottom exterior of e.g. telescopic tube 3 supporting on the inside of telescopic tube 2 and of a length not exceeding the length of the overlay between the two mast sections illustrated 7. Slide rails / shoe E may be split in two (seen in the longitudinal axis of the mast) with one mounted as above and the other mounted at the top of the outer mast section 2 in the example above but such that the total length of the two slides / shoes does not exceed the sections overlay 7.
    By placing a number of slides / shoes (2 or more) around angular mast sections, it is achieved at the same time that the mast is secured against rotation between the individual sections (azimuth) seen in the longitudinal axis of the mast.
    Also shown are examples of rollers for wire / straps for mast telescopic drives. with cut-outs in sliding rails / shoes for these alternatively sliding rails / shoes are placed respectively. wire / straps on each of their surfaces on an angled mast section.
    Figure 4 shows an example of mast mounted in / on armored vehicle.
    The telescopic mast is mounted on a vehicle equipped with wheels but alternatively can be fitted with belt drive. A payload is mounted at the top of the mast. This payload can be, for example, antenna equipment, monitoring equipment, lamps, weapons or other equipment.
