Telescopic Mast
FIELD OF THE INVENTION
The present invention relates to a telescopic mast comprising at least one or more parallel wall telescopic links, wherein one of two adjacent telescopic sections is narrower than the other of the two adjacent telescopic sections so that a telescopic section can be inserted into and out of an adjacent one respectively. 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.
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.
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. As blur occurs between all of the mast's adjacent telescope sections, the blur will accumulate in connection with high masts. Therefore, especially in the case of high telescopic masts, it would be extremely appropriate to minimize the veil that occurs between adjacent telescope sections.
There is the telescopic mast where, in the space between two adjacent telescope sections, means are provided which include actuators and / or mechanisms that can reduce blurring by, for example, pushing the adjacent walls away from each other. These help reduce blurring, but are technically complicated and undesirably contribute to weight gain.
It is desirable that the telescopic mast's sub-elements are not heavier and larger in scope than is most necessary. In order to meet the requirements for reliability and robust construction, it is clearly a disadvantage for a telescopic mast if the technique includes
GB 2017 70947 A1 fragile technical solutions in which errors can occur which means that the telescopic mast cannot be operated quickly, accurately and in all conditions.
A solution is also needed which in a simple way counteracts rotational movement about the longitudinal axis of the mast sections on telescopic masts with one or more extendable telescopic links.
Telescopic masts used in high-load environments are subjected to static as well as dynamic loads. These may, for example, be caused by wind loads as well as loads arising from mobile use.
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 is mounted and / or from the bottom of the telescopic mast in the case of a mobile base / platform.
The rotation control can / will be exposed to very large loads.
There is a desire to counteract rotational movement about the longitudinal axes of the mast sections in telescopic masts used on mobile platforms, for example vehicles, and where there is a requirement / desire for minimal rotation between the sections about the center axis of the mast as the load / payload sitting on the mast can have requirements for direction control as seen on the center axis of the mast. These can be communication antennas, radar, sensors, weapons, etc.
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 blurring and counteract rotational movement of the telescopic sections on the longitudinal axis of the mast. None of the known solutions meet these requirements.
DK 2017 70947 A1
The object of the invention
It is the object of the present invention to provide a telescopic mast where the blurring between the telescopic sections is minimized. It is a further object of the invention to provide a telescopic mast that counteracts rotational movement of the telescope sections and which is lightweight.
Description of the Invention
As mentioned initially, the invention relates to a telescopic mast comprising at least one or more telescopic poles with parallel walls, one of two adjacent telescope sections being narrower than the other of the two adjacent telescope sections, so that a telescopic section can be inserted into and out of one respectively. lying telescopic section in a telescopic link, as well as being able to be inserted into and out of a further telescopic section in a further telescopic link. The telescopic mast is characterized in that in one telescopic section of a telescopic link, a guide rail extending in the axial direction of the telescopic section is provided that at least one spacer is provided between each of the two adjacent telescopic sections. keeping a distance between the telescopic sections and controlling their mutual movement, which includes a mounting bracket attached to the second telescopic section of a telescopic link and a flexible bushing mounted in the mounting bracket, a sliding shoe comprising a pin in the flexible bushing for engagement with the flexible bushing and a groove adapted for engagement with the guide rail.
With a telescopic mast according to the invention, reduction in blur and a rotational control with several advantages are achieved.
The component parts can be produced with very narrow tolerances which means minimal blurring.
The solution is very compact as it is damped with flexible and resilient material in the bushing. The material for making the bushing is resiliently resilient, so that upon impact there may be a change in the position of the hole and thus the sliding shoe relative to the mounting bracket under a load, and that the bushing will return to its initial form after the load has ceased.
DK 2017 70947 A1
Deformations and / or movement in and between the telescope sections of the mast, which amplify the loads on the guide rail / sliding shoes, must not all be taken up as loads in the material; but submerged in the flexible material of the bushing.
The effect of these complex combinations of shock loads in multiple directions and simultaneously will not only have to be absorbed as loads in / between sliding shoes and slides, but will be absorbed and damped in the flexible material.
Advantageously, a telescopic mast according to the invention may be constructed such that a tube is provided within the telescopic sections. In this tube, supply lines and cables of various kinds may be arranged which are used in connection with equipment located at the top of the telescopic mast. For example, these may be antenna equipment, monitoring equipment, lamps, weapons or other equipment.
Thus, with a telescopic mast according to the invention, a number of advantages are obtained, the spacer (s) which resiliently keeping the adjacent walls away from each other minimizes the blurring that occurs between adjacent telescope sections. By pushing the adjacent walls away from each other, the blur is eliminated or minimized.
Furthermore, with the telescopic mast according to the invention, an advantage is obtained by the slides of the sliding shoe interacting with the guide rail, thereby preventing a mutual rotational movement of the telescopic sections around the longitudinal axis of the mast. Furthermore, the construction, which consists of individual elements, will be a light and simple construction.
In addition, in the construction, an advantage is obtained by absorbing impact and impact in the flexible bush between the groove which engages the guide rail on one telescopic section and the mounting bracket attached to the other telescopic section.
Spacers of different nature can be used in both design and material selection. It may be advantageous to manufacture the sliding shoe and sleeve in materials that are shape stable in connection with large temperature fluctuations.
DK 2017 70947 A1
Further, it may be advantageous to provide a coating of the sliding shoe, sleeve and / or guide rail with a layer of friction-reducing material such as e.g. teflon, to minimize friction between and wear of the elements involved.
According to a further embodiment, the telescopic mast according to the invention is characterized in that the guide rail in each telescopic joint is arranged on an inwardly facing side of one telescopic section and that the mounting bracket is arranged on an outwardly facing side of the other telescopic section.
In practice, it has proved most convenient that the guide rail or guide rails in each telescopic link are arranged on an inward facing side for a simple construction. Hereby, the mounting bracket will be located on an outward facing side of the second telescopic section which is located within the first telescopic section. Alternatively, it is possible to reverse this location opposite so that the guide rail in each telescopic link is placed on an outward facing side of the inner telescopic section of a telescopic link.
According to a further embodiment, the telescopic mast according to the invention is characterized in that the flexible bushing is made of a flexible material, so that the sliding shoe can be displaced radially or axially with respect to a central axis through the mounting bracket. Since the flexible bushing is made of a flexible material that allows shear in multiple dimensions, the greatest security is obtained for absorbing shock effects which reduce wear, and at the same time the rotational retention between the different telescope sections is achieved.
As the sliding shoe can be displaced both radially and axially with respect to a central axis through the receiving bracket, shock effects are taken up, regardless of their orientation.
According to a further embodiment, the telescopic mast according to the invention is characterized in that the flexible bushing is made with a mounting hole for accommodating the sliding shoe pin and that the slider shoe pin can rotate in the mounting hole in the bushing. By making the connection between the pin of the sliding shoe and the hole in the bush without a restraint, the rotation in the mounting hole can ensure that even twistings between the two telescopic sections 2017 70947 A1 can be absorbed into the flexible bush. Also, a rotation of the slip of the slider shoe will allow the use of guide rails which do not extend completely axially but may have an oblique orientation with respect to an axial direction parallel to a center axis through the telescopic mast.
According to a further embodiment, the telescopic mast according to the invention is characterized in that for each telescopic link there are provided three or more guide rails distributed along the circumference of the telescopic link. By using multiple guide rails distributed along the circumference of the telescopic link, an even distribution is obtained which accommodates the veil along with the rotation-fixed distribution. By the even distribution of the guide rails and thus also the cooperating spacers, a centering of the inner telescope section in an outer telescope section in a telescopic link can be established. Thus, there may be a single guide rail in a telescopic link, but there may also be two or more guide rails in a telescopic link.
According to a further embodiment, the telescopic mast according to the invention is characterized in that for each guide rail there are provided two or more spacers distributed in the axial direction of the telescopic link. In order to distribute a load and ensure an orientation against rotation, two or more spacers may be provided which are distributed in the telescopic link distributed in the axial direction of the telescopic link. With such a mounting, a torsional twist of one telescopic section relative to the other telescopic section of a telescopic joint is prevented.
