Definitions
- the field of the invention is that of antennas mounted on telescopic masts and connected by cables electronic transmitting and / or receiving modules. More specifically, the present invention relates to a system for guiding cables connected to an antenna mounted on a mobile section of a telescopic mast, this mast comprising at besides a fixed section with respect to which moves in translation of the mobile section.
- the invention applies including tactical antennas.
- the present invention aims in particular to remedy this drawback.
- one of the objectives of the invention is to provide a cable guidance system, connected to a antenna mounted on a mobile section of a telescopic mast, avoiding deterioration of this cable by pulling, twisting or excessive bending, giving it a length of more important life.
- the antenna cable is hung at least at several points on a cable traction over a fraction of its length, the cable traction being fixed between a first fixing point located on the mobile section and a second fixing point located at an intermediate point in the fixed section, the system further comprising a pulley carried by a carriage guided inside the fixed section and driven in it by the traction cable.
- the system of the invention advantageously comprises a carriage return mechanism allowing the mast telescopic to be deployed and folded in all positions.
- the mechanism of carriage return has a return cable attached at the base of the fixed section and on the other hand at the section mobile, the return cable passing successively through a first return pulley fixed to the mobile carriage, by a second deflection pulley fixed to the base of the fixed section and by a third deflection pulley fixed at the end top of the fixed section.
- the mechanism of carriage return has a return cable fixed by its two ends of the mobile section, the return cable passing successively through a first deflection pulley fixed to the base of the fixed section, by a second pulley of return fixed to the mobile carriage, by a third pulley of return fixed to the base of the fixed section and by a fourth return pulley attached to the upper end of the section fixed.
- FIG 1 is a schematic view of a mast telescopic antenna support, this mast being in position folded, provided with the guide system of the invention.
- the Figure 2 shows the same mast in the deployed position.
- the telescopic mast has a fixed section 10 and a mobile section 11.
- the mobile section 11 consists of a truss beam and can be driven, by means not shown, in translation relative to the fixed section 10, to deploy it and fit it into the fixed section 10.
- An antenna 12 is mounted on the mobile section 11, at the end of it.
- the fixed section 10 is for example mounted on a vehicle or fixed to the ground.
- a cable antenna 13 connects antenna 12 to equipment transmission not shown and the mobile section 11 is equipped with guide means 14, for example made up of rollers bearing on the fixed section 10.
- the present invention proposes to hang the antenna cable 13 on a cable traction shown in Figure 3 and referenced 30.
- the antenna cable is shown in lines discontinuous.
- the traction cable 30 is fixed between a first attachment point 31 located on the movable section 11 (Fig. 1 and 2) and a second attachment point 32 located at a intermediate point of the fixed section 10.
- the guiding of the traction cable 30 and, indirectly, antenna cable 13 is provided by a pulley 15 carried by a carriage 16 fitted with wheels and guided inside the fixed section 10.
- the carriage 16 is driven in this section fixed by the pulling cable 30 which supports the constraints.
- the weight of the trolley is optimized so that the pull cable partially wraps around the pulley 15 when deploying and folding the mast telescopic.
- the traction cable can for example be constituted by a steel cable, a strap, a strap or a chain.
- the pulley 15 is adapted to the nature of the cable traction: a toothed pulley, a drum can be used smooth or any other device ensuring a guide the traction cable.
- the function of the cable traction is to ensure the movement of the carriage 16 while preventing the carriage movement efforts from being supported by the antenna cable 13.
- the antenna cable is attached to the pull cable at the less at several points of it, for example using necklaces. It is also possible to use two traction cables extending parallel to each other to each other and connected by a strap, for example stainless steel, this strip comprising means for clipping the or antenna cables. According to another embodiment, the pull cable and antenna cable (s) included in a common sheath, flexible enough that a minimum effort is supported by the antenna cable (s).
- the cable antenna may have an extra length by in relation to the traction cable, between the fixing points of this pull cable.
- the antenna cable is fixed to the traction cable via collars, it is possible to provide a carriage pulley with two different diameters: a large diameter for the traction cable and a smaller diameter for the antenna cable. Passages for necklaces can also be provided on this pulley.
- the device described so far is particularly suitable for antennas that are deployed or folded when is in a position close to the vertical.
- FIG 4 is a schematic view of a mast telescopic antenna support, this mast being in position folded, provided with the guide system of the invention as well as a carriage return mechanism, Figure 5 representing the mast of Figure 4 deployed.
- the return mechanism here includes a return cable 40 shown in broken lines.
- the return cable 40 is fixed on the one hand to the base of the fixed section 10, in one point 41, and on the other hand to the mobile section 11, for example at point 31.
- the return cable 40 passes successively through a first return pulley 42 fixed to the mobile carriage 16, by a second return pulley 43 fixed to the base of the fixed section 10 and by a third deflection pulley 44 fixed to the upper end of the fixed section 10.
- the deployment and folding of the telescopic mast always ensures the movement of the carriage 16 and therefore a guide for the antenna cable.
- This device is particularly advantageous for antenna masts which are wants to be able to fold horizontally or to a position tilted, such as tactical masts.
- one of the return pulleys 42 to 44 is used to ensure deploying and folding the telescopic mast.
- one of the deflection pulleys is coupled to a motor ensuring the translational movement of the movable section by compared to the fixed section.
- This pulley is for example that referenced 43 in FIGS. 4 and 5.
- the return cable 40 in this case also provides a hoisting function of the mobile section, the reminder of the telescopic section being provided by the traction cable carried by the mobile carriage.
- the return mechanism of the carriage has a return cable 60 fixed by its two ends of the movable section 11, at a first point referenced 61 and in a second point which may be point 31.
- the return cable 60 passes successively through a first return pulley 62 fixed to the base of the fixed section 10, by a second return pulley 63 fixed to the mobile carriage 16, by a third return pulley 64 fixed to the base of the fixed section 10 and by a fourth deflection pulley 65 fixed to the upper end of the fixed section 10.
- One of the deflection pulleys can also be coupled to a motor.
- the return cable 60 can be wound up on several turns around pulley 64. Any system can be used motorized (electric, hydraulic winch, ). We assure thus simultaneously deploying and folding the mast telescopic and the recall of the mobile cart 16. This device works in all mast positions, whether vertical, horizontal or inclined.
- the antenna cable (s) may be free between the antenna and the transmission equipment, but we will ensure preferably their attachment to the first attachment point 31 and at the second attachment point 32, for example using cable ties.
- the antenna cable can be a radio cable such as a coaxial cable, a flexible waveguide or a electric cable supplying a demodulator installed near the antenna.
