Description

[Technical field]

[0001] The present invention relates to a mounting apparatus for antenna devices on a support pole, and more particularly to a mounting apparatus for antenna devices on a support pole that can mount two or more antenna devices spaced apart in the vertical direction on a single support clamp, and includes a tilting means and a steering means that can adjust the tilting rotation of the two or more antenna devices in the vertical direction and the steering rotation of the two or more antenna devices in the horizontal direction simultaneously or at different times. [Background technology]

[0002] 2. Description of the Related Art A wireless communication antenna is generally installed in an open, high location in order to facilitate smooth transmission and reception with a wireless communication device located at a long distance.

[0003] For this reason, antennas are installed on utility poles, steel towers, building rooftops, etc., and in particular, when installing antenna equipment on a support pole such as a utility pole, a space usage fee (rental fee) must be paid to the lessor who operates the facility such as the pole.

[0004] However, in the case of a support pole, it is preferable from a cost perspective to install antenna equipment in a concentrated manner in a limited space. However, when antenna equipment is installed in a concentrated manner, there is a concern about radiation interference from surrounding antenna equipment, and there is also a problem that it is difficult to adjust the direction of the antenna equipment (for example, steering rotation adjustment in the left and right direction and tilting rotation adjustment in the up and down direction).

[0005] In addition, as the number of antenna devices installed increases, the external wires for external power supply and the various cables for connecting to the control unit are often exposed to the outside, which acts as a factor that impairs the aesthetic appearance of the area around the support pole. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention has been made to solve the above-mentioned technical problems, and has an object to provide an antenna equipment installation device for a pole that not only enables the concentrated installation of antenna equipment on a pole having a limited space, but also makes it easy to adjust the directionality of the antenna equipment.

[0007] Another object of the present invention is to provide an antenna equipment installation device for a pole, which can install antenna equipment at two locations, one above the other, on a single pole clamp of a pole so as to cover two frequency bands, and can easily adjust the direction of the antenna equipment for each frequency band to a desired position using a tilting means and / or steering means.

[0008] It is yet another object of the present invention to provide an antenna equipment installation device for a pole, which can prevent external exposure of external electric wires or cables provided for the operation of the antenna equipment.

[0009] The objects of the present invention are not limited to those mentioned above, and other objects not mentioned will be clearly understood by those skilled in the art from the following description. [Means for solving the problem]

[0026] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an installation apparatus for an antenna device on a pole according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0027] In assigning reference symbols to components in each drawing, it should be noted that the same components are assigned the same symbols as much as possible even if they are displayed in different drawings. In addition, in describing the embodiments of the present invention, if it is determined that a detailed description of such known configurations or functions would hinder understanding of the embodiments of the present invention, the detailed description will be omitted.

[0028] In describing components of the embodiments of the present invention, terms such as 1, 2, A, B, (a), (b) and the like may be used. Such terms are merely used to distinguish the components from other components, and do not limit the essence, order, or procedure of the components. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention belongs. Terms as defined in commonly used dictionaries should be interpreted as having a meaning consistent with the meaning they have in the context of the relevant art, and should not be interpreted in an idealized or overly formal sense unless expressly defined in this application.

[0029] FIG. 1 is an oblique view showing the installation of an antenna device by an installation device for an antenna device for a pole according to one embodiment of the present invention, FIG. 2 is an exploded oblique view of the antenna device separated from the installation device for an antenna device for a pole in FIG. 1, and FIGS. 3A and 3B are exploded oblique views of the front and rear parts showing the state in which the pole clamp and the directional adjustment unit are separated.

[0030] The installation device for an antenna device for a pole according to an embodiment of the present invention may include pole clamps 10, 110 provided at a middle portion of a pole P, as shown in Figs. 1 to 3B.

[0031] The pole clamps 10, 110 may include an upper clamp 10A, 110A disposed relatively higher and a lower clamp 10B, 110B disposed relatively lower, as shown in FIG.

[0032] Here, as shown in Figures 3A and 3B, if the direction in which the antenna devices A1, A2 are installed with respect to the support pole P is defined as the "inner side" and the opposite direction is defined as the "outer side", the support pole clamps 10, 110 are divided into an outer clamp 10 that is coupled to surround the outer side of the outer circumferential surface of the support pole P, and an inner clamp 110 that is coupled to surround the inner side of the outer circumferential surface of the support pole P.

[0033] First, the upper clamp 110A and lower clamp 110B of the inner clamp 110 are placed so as to surround the inside of the outer peripheral surface of the support pole P, and then the upper clamp 10A and lower clamp 10B of the outer clamp 10 are placed so as to surround the outside of the outer peripheral surface of the support pole P, and the clamps can be stably installed at a desired height on the support pole P using the clamp fixing bolt (11, see Figures 4A and 4B).

[0034] A total of four clamp fixing bolts 11 are provided, which are tiltably assembled in the front-rear direction to both left and right ends of the upper clamps 10A, 110A and both left and right ends of the lower clamps 10B, 110B, respectively.

[0035] Here, the portions of the outer clamp 10 and the inner clamp 110 facing the support pole P are each provided with a clamping gear panel (see reference numeral 12 in FIG. 7A) that adheres closely to the outer circumferential surface of the support pole P by the bolting connecting force transmitted from the clamp fixing bolt 11 to generate a predetermined friction force.

[0036] The clamping gear panels 12 are manufactured in various sizes and specifications to suit the diameters of the support poles P, and are detachably coupled to the outer clamp 10 and the inner clamp 110, respectively.

[0037] Meanwhile, the installation device 100 for an antenna device for a pole according to one embodiment of the present invention may further include a directional adjustment unit 140, 150 including a tilting means 140 for tilting two or more antenna devices A1, A2 connected at a distance in the vertical direction via the pole clamps 10, 110 via left and right tilting axes T1, T2 simultaneously or at different times, and a steering means 150 for steering and rotating the two or more antenna devices A1, A2 in the horizontal direction around the vertical axis.

[0038] The direction adjustment units 140 and 150 refer to means for adjusting the direction in a wide range so that the antenna devices A1 and A2 can efficiently realize beam-forming in desired directions.

[0039] Here, the tilting means 140 is manually tilted by an operator's operation, or is automatically tilted by supplying power to the electrically driven driving motors 130a and 130b.

[0040] Assuming that, as shown in FIG. 9A described later, an electrically driven driving motor (not shown) is provided inside the tilting housing 105, and the tilt bracket 145 is tiltably rotated by the tilting driving force transmitted by the driving motor.

[0041] 9B, a tilting adjustment bolt 143' is provided inside the tilting housing 105 so that an operator can manually rotate it using a predetermined tool, and the tilt bracket 145 is tilted and rotated by a tilting driving force transmitted by the rotation of the tilting adjustment bolt 143'. This will be described in more detail later.

[0042] As shown in Figures 1 to 3B, an installation device for antenna equipment for a pole according to one embodiment of the present invention is provided so that a cable A-3 electrically connecting a control unit (not shown) to a first antenna equipment A1 and a second antenna equipment A2 is concealed so as not to be exposed to the outside.

[0043] For this purpose, the first antenna device A1 and the second antenna device A2 may further include a concealment cover A-2 that covers a plurality of heat sink fins A-11 integrally formed on the rear portion and conceals the cable A-3.

[0044] The concealment cover A-2 serves as a finger guard to prevent the hands and other body parts of the operator or user from directly contacting the high-temperature system heat generated during the system operation of each antenna device A1, A2 when the high-temperature system heat is dissipated through the multiple heat sink fins A-11, and at the same time, as described above, serves to enable the concealed installation of the cable A-3.

[0045] More specifically, assuming that the control unit is provided inside the tilting housing 105 described below, the cable A-3 passes through the steering mounting panel 151 connected to the upper and lower ends of the tilting housing 105 via the tilt bracket 145, and is then directly connected to the connecting terminal A-4 provided on the rear part of the antenna devices A1 and A2, and at this time, the concealment cover A-2 prevents the cable A-3 from being exposed to the outside.

[0046] On the other hand, the concealment cover A-2 is formed with a plurality of through holes A-2h so as to facilitate smooth heat exchange with the outside air of a plurality of heat sink fins A-11 formed integrally with the rear portion of the antenna devices A1 and A2.

[0047] Additionally, although not shown, the concealment cover A-2 can be produced in two halves so as to cover the left half and the right half of the rear parts of the antenna devices A1 and A2, respectively.

[0048] 4A and 4B are a bottom perspective view and a top perspective view showing the directionality adjustment portion, FIG. 5 is a front view of FIG. 1 and a partially enlarged view thereof, and FIG. 6 is a side view of FIG. 1 and a partially enlarged view thereof.

[0049] The steering means 150 of the direction adjustment unit 140, 150 may include an upper steering mounting panel and a lower steering mounting panel 151 to which the lower end surface of any one of the two or more antenna devices A1, A2 (see reference symbol A1 in FIGS. 1 to 3B) is coupled to an upper surface or the upper end surface of the other one of the two or more antenna devices A1, A2 (see reference symbol A2 in FIGS. 1 to 3B) is coupled to a lower surface, at least one guide slot 155 formed by penetrating the upper steering mounting panel and the lower steering mounting panel 151 vertically to correspond to the steering rotation trajectory of the antenna devices A1, A2, and at least one guide bolt 157 that is bolted to the lower or upper part of the antenna devices A1, A2 and that passes through the at least one guide slot 155 and is bolted to the lower or upper part of the antenna devices A1, A2.

[0050] Here, at least one guide slot 155 is provided in pairs on the left and right sides, each pair being spaced apart from the other, and formed within a steering trajectory having a different radius from the upper and lower rotation axes which are the center of steering rotation of the antenna devices A1 and A2. It is also preferable that at least one guide bolt 157 is provided in the number inserted and fastened to each guide slot 155.

[0051] The worker positions the antenna devices A1 and A2 on the upper and lower surfaces of the steering mounting panel 151, and then passes the guide bolt 157 downward or upward through the guide slot 155 and fastens it loosely to adjust it to the pre-designed steering rotation angle. Then, the worker firmly tightens the guide bolt 157 to stably fasten it, thereby installing the antenna devices A1 and A2 on the steering mounting panel 151.

[0052] At this time, the two or more antenna devices A1 and A2 are coupled to the upper steering mounting panel 151 and the lower steering mounting panel 151 within a range of at least one guide slot 155 so as to be able to adjust the steering rotation in the left and right horizontal directions.

[0053] Thus, according to an antenna equipment installation device 100 according to one embodiment of the present invention, as shown in FIG. 5, an upper steering means 150 involved in steering rotation of the first antenna equipment A1 in the left-right direction and an upper tilting means 140 involved in tilting rotation in the front-back direction are arranged on the upper side of the tilting housing 105 connected to the support pole P via the support clamps 10, 110, and an upper steering means 150 involved in steering rotation of the second antenna equipment A2 in the left-right direction and an upper tilting means 140 involved in tilting rotation in the front-back direction are arranged on the lower side of the tilting housing 105 connected to the support pole P via the support clamps 10, 110.

[0054] Meanwhile, the antenna device installation device 100 according to one embodiment of the present invention may further include an external power cable PC for supplying external power from an external power supply unit (not shown) to the antenna devices A1, A2 or a control unit (not shown), as shown in FIG. 6.

[0055] Here, the external electric wire PC is installed concealed from the outside by being inserted inside the support pole P corresponding to the vicinity of the support clamps 10, 110 so as to minimize deterioration of the appearance in the vicinity of the support pole P. For this purpose, the support pole P is formed with a support electric wire installation hole Ph in which the external electric wire PC is housed, in communication with the support pole P.

[0056] In this way, according to the installation device 100 for antenna equipment for a support pole according to one embodiment of the present invention, the external exposure of the cable A-3 connecting the antenna equipment A1, A2 to the control unit and the external electric wire PC connected to the control unit is minimized, thereby providing the advantage of preventing a deterioration in the appearance around the support pole P.

[0057] However, in the installation device 100 for antenna devices for a pole according to one embodiment of the present invention described above, the first antenna device A1 and the second antenna device A2 must be provided so as to be tiltably rotated in the front-rear direction from above and below based on the tilting housing 105 described below, and therefore must be horizontally spaced a predetermined distance or more from the pole P to prevent interference during tilting rotation. In this case, the tilting housing 105 may have to bear the moment load of the antenna devices A1 and A2, which acts relatively large.

[0058] Hereinafter, another embodiment will be disclosed that can solve the above-mentioned problems and completely solve the problem of the exposure of the external electric wire PC between the pole electric wire installation hole Ph of the pole P and the tilting housing 105. In addition, the tilting means 140, which has not yet been described among the direction adjustment units 140 and 150, will be described in detail below.

[0059] Figures 7A and 7B are rear and front exploded oblique views of a partial configuration showing an installation device for an antenna equipment for a mast pole according to another embodiment of the present invention, Figure 8 is a partially enlarged oblique view showing the installation on a mast pole of the antenna equipment for a mast pole according to another embodiment of the present invention shown in Figures 7A and 7B, and Figures 9A and 9B are cross-sectional views taken along line "I-I" in Figure 5, respectively showing a tilting means that can be operated automatically (see Figure 9A) and manually (see Figure 9B).

[0060] As shown in Figures 7A to 9B, the installation device 100 for an antenna device for a pole according to another embodiment of the present invention may further include a wire storage box 160 that is disposed between the pole clamps 10, 110 and the tilting housing 105 of the tilting means 140 described later, and that conceals and stores at least one external wire PC that is electrically connected to at least two antenna devices A1, A2.

[0061] The wire storage box 160 is formed in an approximately hexahedral box shape, with the front surface 163 being firmly fixed to the rear surface of the tilting housing 105, and the rear surface 161 being fixed at four points by a screw connection method using fixing screws 165 to the upper clamp 110A and the lower clamp 110B of the inner clamp 110 of the pillar clamps 10, 110.

[0062] To this end, a screw through hole 162 through which the fixing screw 165 passes is formed on the rear surface 161 of the wire housing box 160, and a screw fastening hole 115 through which the fixing screw 165 is fastened is formed on the upper clamp 110A and the lower clamp 110B, respectively.

[0063] The wire storage box 160 is formed of a panel made of a rigid material having a rigidity sufficient to withstand at least the moment load of the antenna devices A1 and A2, and is formed in a hollow box shape. At least one wire through hole 164 is formed on the front surface 163 so that the external wire PC can pass through and be inserted into the tilting housing 105 side.

[0064] Here, the pole electric wire installation hole Ph formed in the pole P is formed between the upper clamp 110A and the lower clamp 110B (not shown), and is thereby concealed by the electric wire storage box 160, making it possible to completely block exposure of the external electric wire PC.

[0065] In this way, the antenna equipment installation device 100 for a pole according to another embodiment of the present invention provides the advantage that, by additionally providing the wire storage box 160, a horizontal separation distance between the pole P and the antenna equipment A1, A2 can be secured, thereby preventing tilting rotation interference between the antenna equipment A1, A2 in advance and completely preventing the external exposure of the external wires PC.

[0066] Meanwhile, the tilting means 140 of the direction adjustment units 140, 150 may include an upper tilting means for tilting the first antenna device A1 located relatively at the upper position, and a lower tilting means for tilting the second antenna device A2 located relatively at the lower position, as shown in Figures 7A to 9B.

[0067] Here, the upper tilting means and the lower tilting means differ only in the installed antenna devices A1 and A2, and their configurations are arranged completely symmetrically above and below based on the tilting housing 110 described later. However, hereinafter, the upper tilting means and the lower tilting means will not be described separately, but the upper tilting means will be mainly described in detail.

[0068] The tilting means 140 includes a tilting housing 105 connected to the pillar clamps 10, 110, a driving motor (not shown in the drawing) provided inside the tilting housing 105 and electrically driven to rotate, a gear set 142 that reduces the rotational force of the driving motor when it is input and outputs it, and a worm wheel gear unit 144 that constitutes a tilting shaft by axially penetrating the tilting housing 105 in the left-right direction and that rotates by receiving the driving force output from the gear set 142 through worm wheel gear teeth formed on the outer circumferential surface.

[0069] Here, the tilting means 140 may further include a worm gear portion 143 that is disposed between the gear set 142 and the worm wheel gear portion 144, extends from the rotation axis of any one of the gears of the gear set 142, and has worm gear teeth formed thereon that mesh with the worm wheel gear teeth of the worm wheel gear portion 144.

[0070] More specifically, as shown in FIG. 9A, when the drive motor rotates, the gear set 142 receives the rotational force of the drive motor, reduces the rotational force at a predetermined reduction ratio, and outputs the reduced rotational force. The rotational drive force output from the gear set 142 is transmitted to the worm wheel gear unit 144 via the worm gear unit 143, and the worm wheel gear unit 144 constituting the tilting shaft rotates, thereby automatically adjusting the tilting rotation of the antenna devices A1 and A2.

[0071] However, it is not necessary that the tilting means 140 is provided so as to perform the tilting operation automatically by a drive motor.

[0072] That is, as shown in FIG. 9B, the tilting means 140 includes a tilting housing 105 connected to the pillar clamps 10, 110, a tilting adjustment bolt 143' arranged inside the tilting housing 105 to rotate around a horizontal rotation axis in the front-to-rear direction and having worm gear teeth formed on its outer circumferential surface, and a worm wheel gear portion 144 that penetrates the tilting housing 110 in the left-right direction to form a tilting axis and rotates by meshing between the worm wheel gear teeth formed on the outer circumferential surface and the worm gear teeth of the tilting adjustment bolt 143'.

[0073] The tilting adjustment bolts 143' are arranged so that their heads are exposed to the front surface of the tilting housing 105, and an operator can adjust the tilting angles of the antenna devices A1 and A2 by rotating the tilting adjustment bolts 143' in one direction or the other using a predetermined adjustment tool (such as a screwdriver or hexagonal wrench). The heads of the tilting adjustment bolts 143' exposed to the front surface of the tilting housing 105 are covered by bolt caps 141A and 141B, respectively.

[0074] Here, the tilting means 140 is provided on the upper and lower sides with respect to the tilting housing 105, and the upper tilting adjustment bolt 143' can be defined as the "upper tilting adjustment bolt", and the lower tilting adjustment bolt 143' can be defined as the "lower tilting adjustment bolt", and similarly, the upper worm wheel gear portion 144 can be defined as the "upper worm wheel gear portion", and the lower worm wheel gear portion 144 can be defined as the "lower worm wheel gear portion".

[0075] Thus, the manually operated type tilting means 140 described with reference to FIG. 9B differs from the tilting means 140 described in FIG. 9A in that the drive motor and gear set 142 are omitted, and instead a tilting adjustment bolt 143' that performs a function similar to that of the worm gear portion 143 is provided, thereby providing the advantage of simplifying the internal structure of the tilting housing 105.

[0076] Meanwhile, two or more antenna devices A1, A2 can be coupled via a steering mounting panel 151 to a pair of tilt brackets 145 connected to rotate coaxially with a worm wheel gear portion 144 constituting a tilting shaft.

[0077] More specifically, both ends of a worm wheel gear portion 144 constituting the tilting shaft are connected to tilt brackets 145 arranged parallel to the outer surface of the tilting housing 105 .

[0078] Here, when the worm wheel gear portion 144 rotates, the pair of tilt brackets 145 rotate in conjunction with the worm wheel gear portion 144, causing the steering mounting panel 151 formed integrally with one end of the pair of tilt brackets 145 to rotate about the tilting axis, thereby tilting and rotating the antenna devices A1 and A2.

[0079] For reference, an arrow-like indicator symbol is printed on the pair of tilt brackets 145 so that an operator can recognize the tilting angle, and a tilting angle gauge 146 indicated by an arrow is printed on the outer surface of the tilting housing 105, which corresponds to the outside of the rotation radius of the tilt brackets 145.

[0080] Therefore, the operator can precisely adjust the first antenna unit A1 and the second antenna unit A2 to the desired tilting angle while watching the arrow and the tilting angle gauge 146.

[0081] FIG. 10 is a side view showing the antenna device of FIG. 1 after tilting.
