Abstract

A restraint assembly includes a plurality of tensile restraints and a plurality of restraints. Each tensile restraint of the plurality of tensile restraints is configured to couple to a respective anchor plate of a plurality of anchor plates disposed on one or more foundations, and a mobile system. The mobile system is disposed on the one or more foundations. Each restraint includes a rigid element configured to couple to a respective anchor plate of the plurality of anchor plates, and to interface with or couple to a respective location on the mobile system.

First claim

The invention claimed is:

1. A system comprising:
a restraint assembly configured to restrain at least one trailer of a mobile power plant system, wherein the restraint assembly comprises a plurality of restraints configured to be arranged around the at least one trailer at different axial positions relative to a trailer axis of the at least one trailer,
wherein each of the plurality of restraints is configured to extend downwardly from a first interface with the at least one trailer to a second interface coupled with a foundation supporting wheels of the at least one trailer,
wherein the plurality of restraints is configured to resist movement of the at least one trailer in response to an external load in any direction caused by at least one of wind and seismic conditions,
wherein the plurality of restraints comprises a plurality of different types of restraints configured to be distributed around the at least one trailer based on a load distribution on the at least one trailer, and
wherein the plurality of different types of restraints of the restraint assembly comprises one or more tensile restraints configured to be flexible and loaded in tension between connections with the at least one trailer and the foundation, one or more fastened restraints configured to be rigid between connections with the at least one trailer and the foundation, and one or more interface restraints configured to be rigid between the at least one trailer and the foundation while providing at least one degree of freedom.

2. The system of claim 1 , comprising the mobile power plant system having the at least one trailer that includes first and second trailers, wherein the restraint assembly is configured to maintain an orientation of a first axis of a first component disposed on the first trailer relative to a second axis of a second component disposed on the second trailer, the restraint assembly is configured to maintain the first trailer at a first position relative to the foundation, the orientation of the first axis relative to the second axis is a coaxial orientation, the first axis is a first rotational axis of the first component, and the second axis is a second rotational axis of the second component.

3. The system of claim 2 , wherein the first component comprises a turbine disposed about a shaft along the first axis, and the second component comprises a generator disposed about a generator shaft along the second axis, wherein the shaft is coupled to the generator shaft.

4. The system of claim 1 , wherein each tensile restraint of the one or more tensile restraints comprises:
an anchor plate configured as the second interface coupled to the foundation;
a first end coupled to the anchor plate; and
a second end coupled to a lashing member configured as the first interface at a location on the at least one trailer;
wherein each tensile restraint of the plurality of tensile restraints is configured to support a tensile load between the foundation and the at least one trailer.

5. The system of claim 1 , wherein each fastened restraint of the one or more fastened restraints comprises:
an anchor plate configured as the second interface coupled to the foundation; and
a rigid element coupled to the anchor plate and configured to be coupled to a location on the at least one trailer via the first interface, wherein the rigid element is configured to restrict movement of the location along the trailer axis, a vertical axis, and a lateral axis.

6. The system of claim 5 , wherein the one or more fastened restraints comprises a fastener configured to couple the rigid element to the location on the at least one trailer.

7. The system of claim 1 , wherein each interface restraint of the one or more interface restraints comprises:
an anchor plate configured as the second interface coupled to the foundation; and
a rigid element coupled to the anchor plate and configured to interface with a location on the at least one trailer via the first interface without coupling to the location.

8. The system of claim 1 , comprising a plurality of the tensile restraints, a plurality of the fastened restraints, and a plurality of the interface restraints.

9. The system of claim 1 , comprising the mobile power plant system having the at least one trailer with a turbine and a generator driven by the turbine.

10. The system of claim 9 , wherein the at least one trailer comprises a first trailer supporting the turbine and a second trailer supporting the generator.

11. The system of claim 1 , wherein the one or more interface restraints are configured to provide two degrees of freedom.

12. The system of claim 1 , wherein the one or more tensile restraints comprise a cable or a strap.

13. The system of claim 1 , wherein the plurality of different types of restraints comprises a first restraint type configured to be disposed adjacent a first portion of the load distribution on the at least one trailer and a second restraint type configured to be disposed adjacent a second portion of the load distribution on the at least one trailer, wherein the first portion is relatively heavier than the second portion.

14. The system of claim 13 , wherein the first restraint type comprises the one or more tensile restraints, and the second restraint type comprises the one or more fastened restraints and/or the one or more interface restraints.

15. The system of claim 1 , wherein the different types of restraints comprise first and second restraint types, the first restraint type is configured to support more tensile loads or lighter loads than the second restraint type, and the second restraint type is configured to support more shear loads or compressive loads than the first restraint type.

16. The system of claim 15 , wherein the first restraint type comprises the one or more tensile restraints, and the second restraint type comprises the one or more fastened restraints and/or the one or more interface restraints.

17. The system of claim 13 , comprising the at least one trailer having a turbine or a generator disposed on the at least one trailer, wherein the turbine or the generator represents the first portion of the load distribution.

18. The system of claim 13 , wherein the first restraint type is disposed at a first end portion of the at least one trailer and the second restraint type is disposed at a second end portion of the at least one trailer.

19. The system of claim 1 , wherein the plurality of tensile restraints comprises a plurality of sets of tensile restraints, wherein each of the sets of tensile restraints has first and second tensile restraints configured to be angled away from one another from the at least one trailer toward the foundation.

20. The system of claim 1 , wherein the plurality of restraints comprises at least one set of four restraints configured to be arranged in an X-shaped pattern between the at least one trailer and the foundation, the X-shaped pattern comprises a first V-shaped pattern of two restraints on a first side of the at least one trailer and a second V-shaped pattern of two restraints on a second side of the at least one trailer, and the first and second sides are opposite from one another.

21. The system of claim 1 , wherein at least one of the plurality of restraints is configured to be disposed at or between adjacent wheels of the at least one trailer.
