Abstract

Antenna tower construction/deconstruction biasing assemblies are provided. The biasing assemblies can be configured to extend between a standard and an antenna tower. The assemblies can include: an adjustable linear extension extending between a first end configured to couple with the standard and a second end configured to couple with the antenna tower; and a biasing mechanism configured to adjust the length of the linear extension and maintain the rigid engagement during transitioning of the tower from a down/erect position to an erect/down position. Methods for constructing/deconstructing an antenna tower are provided. The methods can include providing a biasing assembly.

DESCRIPTION

(10) This disclosure is submitted in furtherance of the constitutional purposes of the U.S. Patent Laws to promote the progress of science and useful arts (Article 1, Section 8).

(11) The present disclosure will be described with reference to FIGS. 1A-7. Referring first to FIG. 1A, an antenna tower construction stage 10 is shown with antenna tower 12 rotationally coupled (pivotably attached) to antenna tower base (ground structure) 14 and being raised to position 22 via line (cable or chain) 20 attached to a winch assembly 18 and standard (fixed assembly) 16. In accordance with example implementations and with reference to FIG. 1B, tower 12 can be raised into place (erect position), and as it is raised into place, the momentum of the tower reaching its peak position can cause instability 24 and 26 at line 20 and tower 12. Accordingly, this instability can damage the tower and may in fact snap the line and result in the tower returning to its deconstructed (down) state, thereby potentially injuring those about the tower.

(12) Referring next to FIG. 1C, during deconstruction (lowering), similar instability can occur, in that line 20 can be in a slack position, and tower 12 can be forced to a line non-slack position 26. Line 20 non-slack position is shown in FIG. 1D. This non-slack position can result in instability 26 and 24, again risking danger to the antenna tower and the operators or contractors associated therewith.

(13) Referring next to FIGS. 2A-2C, in accordance with example implementations, stability assembly 30 is provided and can be utilized when raising tower 12 about pivot point 14 utilizing line 20. Pivot point 14 can be the rotational coupling of the tower to the antenna tower base. In accordance with at least one example implementation, this coupling can be a hinge. As tower 12 is raised into place (erect position), tension on line 20 is maintained by having stability assembly 30 engage at least a portion of tower 12 and put resistance against tower 12 as it is raised into place, thereby as winch 18 is retrieving line 20, tension on stability assembly 30 is reduced, allowing tower 12 to gain the erect position without instability 26 or 24. As shown, stability assembly 30 is engaged with standard 18 in a rather normal dimensional relationship, however angled relationships other than normal are also contemplated.

(14) Referring next to FIGS. 3A-3B, stability assembly 30 can be utilized to place tension on line 20, allowing line 20 to be un-winched from standard 16, and allowing tower 12 to be lowered to the deconstructed position without the instability shown in FIGS. 1C-1D. In accordance with example implementations, assembly 30 can engage at least a portion of tower 12 when tower 12 is in the erect position and while line 20 is extended, the stability assembly can be extended to maintain tension in line 20 while moving tower 12 to a teetering position. Upon sufficient line being extended to allow the tower to maintain tension in the line, the stability assembly can be disengaged from the tower.

(15) Referring next to FIG. 4, in at least one stage, an example stability assembly 30 is shown disengaged from tower 12 while line 20 is directing tower 12 to the erect position.

(16) Referring next to FIG. 5, stability assembly 30 is shown engaged with tower 12 and coupling component 50 and component 54 operably engaged to bias with component 56 about biasing assembly 52. Coupling component 50 can be constructed of a complimentary configuration to mate with but slidably engage the portion of tower 12. In the shown embodiment, this coupling is a half section of a tube that is sufficiently large to engage a tube portion of tower 12. Other configurations are contemplated include square or rotating configurations such as those shown in FIG. 8 below.

(17) In accordance with example implementations, component 54 can be a tube, to received complimentary threaded bolt 56, and assembly 52 can be operational to engage the threading of bolt 56 to within tube 54 as component assembly 58 engages standard 16, according to example implementations. Inside component assembly 58 can be a nut welded to bolt 56 to affix it from turning. The nut inside assembly 52 screws in and/or out to extend or retract the tube 54 in and/or out. Tube 54 can float in and/or out as bolt 56 is long enough to stop when the cable 20 is at the right tension to take over and not run out of thread.

(18) Referring next to FIG. 6, component assembly 58 is shown in more detail as a block and cinch assembly, as well as coupling component 50 and internal conduit 54 as well as threaded bolt 56.

(19) Referring next to FIG. 7, stability assembly 30 is shown assembled having component assembly 58 configured for coupling to a standard, adjustable biasing assembly 52 as well as bolt 56, conduit 54, and coupling component 50. Additionally, bushing 53 can be provided. As mentioned previously, FIG. 8 provides another example of a coupling component 50 which is configured to rotate as the tower is raised or lowered into position.

(20) In accordance with example implementations, and with reference to the above assemblies, tower assemblies can be raised and lowered into position relatively safely and with little damage to the tower and/or those constructing or deconstructing the tower. In accordance with example implementations, various towers can be constructed/deconstructed using these assemblies and/or methods. For example, 52 ft towers typically having three sections, 72 ft towers typically having four sections, and/or 89 ft towers typically having five sections can be constructed.

(21) In compliance with the statute, embodiments of the invention have been described in language more or less specific as to structural and methodical features. It is to be understood, however, that the entire invention is not limited to the specific features and/or embodiments shown and/or described, since the disclosed embodiments comprise forms of putting the invention into effect.
