Abstract

The present invention relates to a clamping apparatus for an antenna and, particularly, to a clamping apparatus for an antenna, comprising: an arm unit which is coupled to a support pole vertically provided in the up-and-down direction and extends in the horizontal direction with respect to the support pole; a clamping unit having one end provided with an antenna device and the other end coupled to the distal end of the arm unit, wherein the clamping unit is provided to be rotatable leftward and rightward or to be tiltable upward and downward, so as to rotate the antenna device; and a rotation-auxiliary mounting unit coupled onto the support pole corresponding to the lower part of the arm unit, wherein when a rotation angle of the arm unit is changed, the rotation-auxiliary mounting unit rotatably supports the arm unit in the rotation direction of the arm unit while supporting the weights of the arm unit and the antenna device. Therefore, the clamping apparatus enables easy installation of the antenna device by an individual installer and easy direction adjustment thereof.

First claim

The invention claimed is:

1. A clamping apparatus for an antenna comprising:
an arm unit configured to couple with and extend horizontally from a vertical support pole;
a clamping part having one end coupled with a front end of the arm unit and another end configured to connect to an antenna device so as to be left and right rotatable or to be up and down tiltable, and configured to rotate the antenna device; and
a rotation assist mounting part configured to attach to the support pole corresponding to a bottom of the arm unit and configured to rotatably support the arm unit in a rotation direction of the arm unit while supporting a weight of the arm unit and the antenna device when a rotation angle of the arm unit is changed,
wherein the arm unit comprises:
a fixing type bracket integrated and provided at an end of an arm main body and is configured to be disposed in contact with an outer circumference surface of the support pole; and
a separation type bracket configured to be disposed in contact with the outer circumference surface of the support pole on a side opposite to the fixing type bracket with respect to the support pole and coupled with the fixing type bracket by multiple fixing-long bolts and fixing nuts,
wherein the rotation assist mounting part comprises:
a support panel part configured to support a weight of the arm unit, the clamping part and the antenna device; and
a rotation support part configured to support the rotation of the arm unit,

wherein the support panel part comprises:
a main support panel which has a horizontal surface so that bottom surfaces of the fixing type bracket and separation type bracket of the arm unit are simultaneously supported; and
a coupling panel provided at a bottom of the main support panel and has a surface which is configured to be in contact with a part of the outer circumference surface of the support pole,

wherein the main support panel is a “U”-shaped panel that comprises two substantially parallel straight legs, each having a distal end configured to be positioned beneath the fixing type bracket, and a semicircular portion that integrally connects the two legs and is configured to be positioned beneath the separation bracket, forming a cavity configured to enclose a full radius of the support pole.

2. The clamping apparatus of claim 1 , wherein the arm main body is configured to extend in a given length in a horizontal direction on any one of a first side and a second side of the support pole.

3. The clamping apparatus of claim 1 , further comprising:
a sub-support panel comprising a top supporting the bottom of the main support panel and a side supporting an outside of the coupling panel.

4. The clamping apparatus of claim 3 , wherein the sub-support panel is provided in plural along an outer circumference of the coupling panel.

5. The clamping apparatus of claim 3 , wherein the rotation assist mounting part further comprises a fixing band configured to fix the coupling panel to the support pole.

6. The clamping apparatus of claim 5 , wherein the fixing band is configured to be in contact with the outer circumference surface of the support pole while surrounding a part of the outside of the coupling panel.

7. The clamping apparatus of claim 5 , wherein the fixing band is configured to be coupled with the coupling panel and the support pole by using any one of a welding coupling method and a fastening method.

8. The clamping apparatus of claim 5 , wherein:
at least one band through hole through which the fixing band penetrates from an outside of the coupling panel to an inside thereof is formed in the coupling panel, and
at least one band accommodation hole in which the fixing band is accommodated between the sub-support panel and the outside of the coupling panel is formed in the sub-support panel.

9. The clamping apparatus of claim 3 , wherein the rotation support part comprises a plurality of ball bearing assemblies disposed to protrude upward from the support panel part and configured to be isolated from each other at a given distance in a circumferential direction of the support pole.

10. The clamping apparatus of claim 9 , wherein the ball bearing assembly comprises:
ball accommodation blocks seated in and fixed to rotation part-seated holes, respectively, formed in plural in the main support panel of the support panel part; and
bearing balls accommodated in the ball accommodation holes formed in the ball accommodation blocks, respectively, so that a part of an outer circumference surface of each of the bearing balls is exposed to an outside.

11. The clamping apparatus of claim 10 , wherein the ball bearing assembly further comprises a lubricant coated on an inside of the ball accommodation hole and configured to reduce a frictional force when the bearing ball rotates.

12. The clamping apparatus of claim 10 , wherein the rotation part-seated holes in which the ball accommodation blocks are seated and assembled are formed in the main support panel in a way to up and down penetrate the main support panel.
