Description

Structure of the antenna pole &

The present invention relates to a structure of an antenna pole, and more particularly, to a structure of an antenna pole which is lightweight with a composite laminated structure using a glass fiber and carbon, and has excellent resilience and restoring force even when an external force is deformed, will be.

Generally, an antenna pole is installed in a pole or a pole located at the uppermost position in a separate device or a vehicle, and then the pole is raised to photograph a desired place at a high position, Can be used as.

The antenna pole is configured such that a plurality of cylindrical poles are inserted so as to be superimposed on each other and configured to be raised and lowered while vertically moving.

In the antenna pole, the movable pawls are inserted into the base pawls in descending order of diameters, and the worm coupled to the pulley shaft passing through the gear box is connected to the operating pulley by the driving force of the forward and reverse motors, The worm gear is driven by the worm to rotate the threaded shaft of the threaded spindle shaft in a threaded connection inside the threaded shaft connected to the inside of the pawl so that the threaded shaft is rotated and the movable guide is rotated When the pawl rises, the movable pawl is raised in such a manner that the movable pawl is raised while the sleeve is engaged with the movable ring coupled to the movable paw sequentially.

In order to reduce the weight of the conventional antenna pole, the diameter of the movable pole is made variously. The diameter of the inner pole is larger than the diameter of the inner pole, and the antenna pole is vertically operated.

In this case, the conventional antenna pole is operated at a height of several tens of meters at the time of ascending and descending. When the movable pole is formed of a metal material, if the deformation is easily caused by bending stress, there is no elastic restoring force to restore the original state. there was.

In addition, even if the conventional antenna pole is made of a metal material, even if there is no bending deformation, when an external force such as a shaking or a strong wind generated when moving in an elevated state acts, the stress is concentrated on the connecting portion.

In addition, when the conventional antenna pole is made of a metal material and a temperature change occurs at a high temperature or a low temperature, the thermal expansion and contraction are totally generated, so that a clearance or an excessive tightening phenomenon occurs at a connected portion.

In addition, in the conventional antenna pole, a rotation preventing key groove is formed along the inner surface longitudinal direction of the movable pole, and a key is engaged with the outer surface of the movable pole to move the key in the rotation preventing key groove during vertical movement, However, there is a problem in that a separate manufacturing process step is required after manufacturing the pole for this purpose, and a gap is created due to abrasion due to friction between the rotation preventing keyway and the key.

In addition, in order to determine the ascending order of the conventional antenna pole, a plurality of bolts formed on the movable pole are tightened and loosened, and it is inconvenient to adjust the pressing force of the stopper by adjusting the frictional force with the movable pole located inside the stopper .

When the frictional force with the stopper when the movable pole ascends and descends is increased due to the pressurizing operation of the movable pole, the conventional antenna pole is easily heated or broken and the durability is lowered there was.

This makes it possible to form a key on the inner surface of the movable pole by using a multilayer structure using glass fiber and carbon and to easily form a key groove on the corresponding movable pole and to improve the abrasion resistance of the glass fiber and the supporting function and stability against the external force of carbon An improved antenna pole is required which does not require a work for adjusting the ascending / descending order which can generate a latching force by the operation of the operating pole when the mobile terminal is moved up and down.

At this time, when the magnet 16 is lowered to the lowest height of the n-th working pole 15n of the claw portion 10, the magnet sensor 11b detects the rotation speed of the speed reducer 44 recorded in the controller 60 And a signal for stopping the forward and reverse motors 50 from being driven.

Accordingly, the conventional antenna pole has a problem that when the pole is formed of aluminum, the pole moves up to about 6 to 10 meters or more, or when the external force is applied by strong wind or the like, the pole is warped On the other hand, the antenna pole 100 of the present invention includes a glass fiber layer 10b having excellent strength against impact and breakage, and a carbon layer 10c excellent in stability against deflection and excellent in stability even when deformation occurs, There is a characteristic that deformation does not occur by forming the claw portion 10.

In addition, the conventional antenna pole has a problem in that when the material of the pole is formed of aluminum and the antenna pole 100 is bent, Can be restored even if deformation occurs due to the carbon layer 10c.

The conventional antenna pole has a problem in that the material of the pole is formed of aluminum and the portion of the up and down movement of the antenna is made of metal to increase the total weight and load is generated in the motor for the up and down movement. 100 has a structure in which the pole portion 10 and the up and down movement driving portion 40 are formed in a multilayer structure in which a glass fiber or carbon is laminated so as to reduce the total weight so as to significantly reduce the operating load on the forward and reverse motors 50, .

In addition, the conventional antenna pole adopts a method using a belt and a pulley in order to transfer the driving force of the motor to the lifting and lowering driving unit, and the weight is increased, and cutting accidents due to stiction or pinching may occur in the driving part. The antenna pole 100 of the present invention adopts a structure in which the forward and reverse motors 50, the speed reducer 44, the worm 45 and the worm wheel 42 are not exposed to the outside, There is a structurally safe feature that prevents a safety accident from occurring.

In addition, the conventional antenna pole adjusts the operation order by adjusting the pressing force acting on the movable pole in contact with the stopper by tightening the bolts of the movable ring in order to operate in order when the plural movable poles are moved up and down. There is a problem that the frictional force between the stopper and the movable pole is increased and the load during the driving of the motor due to the frictional force causes the decrease in durability and failure. When the first to nth movable pawls 13a to 13n are moved up to the maximum lifting position, the first and second sleeve ends 15a to 15n are pressed while being in contact with each other, There is a characteristic that load is not generated in the load.

In addition, in the conventional antenna pole, when a plurality of movable pawls are lifted and lowered, a separate sleeve is fastened to the lower end of the movable pawl to push up the movable ring of the next movable pawl, The antenna pole 100 of the present invention has the first sleeve end 15a to the nth sleeve end 15n integrally formed with the pawl body 17 so that the assembly is simple and the weight .

The antenna pawl 100 is lifted up and operated by the first and second movable pawls 15a and 15b different from the nth movable pawl 13n on which the installation equipment 1 is installed, The elevating, lowering, and position are fixed by the helical clamping method of the fixing device 41b (41c), so that even if the installation equipment (1) is heavy, settlement due to load does not occur and accurate operation can be performed.

In addition, all the operating states and controls can be confirmed through the display window 61 of the controller 60. The normal state and the non-state are displayed in different colors through the lamp 62, There is a feature that can be easily understood.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limited to the embodiments set forth herein. Various changes and modifications may be made by those skilled in the art.
