Machines, systems, and methods for truss installation and assembly
An assembly for a truss foundation embedment and installation machine. The machine mast has a rotary driver, target assembly, and a truss component holder. After a pair of foundation components are embedded, the truss component holder is moved to an orientation location that aligns the rotational axis of a specific tracker bearing with respect to a work point of the truss foundation. A truss cap is placed on the truss component holder and held in place while upper leg sections are sleeved over the truss cap and down onto the embedded foundation components. A hydraulic crimper is used to crimp the portions of each upper leg section that overlap with the truss cap and the embedded foundation components to unify the truss foundation.
1. An assembly for a machine for embedding foundation components and assembling truss foundations, the assembly comprising:
an elongated mast;
at least one crimping device attached to the mast;
a first movable assembly;
a rotary driver attached to the first movable assembly and controllable to rotate foundation components into underlying ground; and
a jig for holding a truss component in place while attached to a set of foundation components embedded by the machine to form a truss foundation.
2. The assembly according to claim 1 , further comprising an alignment target attached to the first movable assembly for aligning a position of the jig with respect to a predetermined location in free space.
3. The assembly according to claim 2 , wherein the truss component is a truss cap for a specific tracker and the alignment target aligns a position of the truss cap so that a rotational axis of the specific tracker is oriented at known position with respect to a work point of the truss foundation.
4. The assembly according to claim 1 , further comprising a motor attached to the mast for moving the first movable assembly along the mast.
5. The assembly according to claim 4 , further comprising at least one drive chain linked to the first movable assembly.
6. The assembly according to claim 1 , wherein the mast is movably coupled to a machine to embed foundation components into underlying ground at angles with respect to vertical.
7. The assembly according to claim 1 , wherein the truss component is a bearing adapter.
8. A mast for a machine for embedding foundation components and assembling truss foundations, the mast comprising:
at least one rail extending along the mast;
a first movable assembly movable along the at least one rail;
a motor connected to the first movable assembly to move the assembly along the at least one rail;
a rotary driver attached to the first movable assembly for driving a pair of foundation components into underlying ground;
a jig for holding an apex truss component above a pair of embedded foundation components at a specific location relative to a work point at an intersection of a central longitudinal axis of each of the pair of embedded foundation components; and
at least one crimping device for connecting the apex truss component to the embedded foundation components.
9. The mast according to claim 8 , wherein the pair of foundation components are hollow screw anchors.
10. The mast according to claim 8 , wherein the apex truss component is a truss cap.
11. The mast according to claim 8 , wherein the apex truss component is a bearing adapter.
12. The mast according to claim 8 , further comprising a target assembly attached to the first movable assembly.
13. A method of installing and assembling a truss foundation with an automated installation and assembly machine, the method comprising:
embedding a pair of foundation components into underlying ground with a rotary driver on the mast of an embedment machine;
orienting an assembly containing a target to an orientation position above the pair of embedded foundation components;
attaching a truss apex component to a component holder on the assembly;
sleeving upper leg sections on to the truss apex component and onto the embedded foundation components; and
crimping the portions of the upper leg sections overlapping with the truss apex component and the embedded foundation components to unify the truss foundation.
14. The method according to claim 13 , wherein orienting an assembly containing a target to an orientation position comprises orienting the assembly so that the truss apex component will align a bearing of a specific tracker relative to a work point of the truss foundation formed by the embedded foundation components, upper leg sections, and truss cap.
15. The method according to claim 13 , wherein the crimping comprises crimping with a hydraulic crimper.
16. The method according to claim 13 , wherein the truss apex component comprises a truss cap.
17. The method according to claim 13 , wherein the truss apex component comprises a bearing adapter.
