Abstract

An apparatus comprises a housing including a housing first portion having a first joint portion configured to overlap a second joint portion of a housing second portion so as to form a housing joint. A primary clamp is positioned at a primary location of the housing joint which abuts at least a portion of the first and the second joint portion. A mounting bracket is positioned on and contacts the primary clamp. A plurality of secondary clamps are positioned at secondary locations, each of which is different than the primary location, of the housing joint. A band is operatively coupled to the mounting bracket by positioning around and contacting each of the plurality of secondary clamps. The band is tightened to urge the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint to secure the housing joint.

First claim

What is claimed is:

1. An apparatus, comprising:
a housing including a housing first portion and a housing second portion, the housing first portion including a first joint portion configured to overlap a second joint portion of the housing section portion so as to form a housing joint;
a primary clamp positioned at a primary location of the housing joint, the primary clamp abutting at least a portion of the first joint portion and the second joint portion;
a mounting bracket positioned on and contacting the primary clamp;
a plurality of secondary clamps positioned at secondary locations of the housing joint, each of the plurality of secondary locations being different than the primary location, the plurality of secondary clamps abutting at least a portion of the first joint portion and the second joint portion;
a band operatively coupled to the mounting bracket, the band positioned around and contacting each of the plurality of secondary clamps, the band comprising a band first portion and a band second portion, the first and second band portions being formed as separate pieces; and
a winch;
wherein the band is configured to be tightened so as to urge the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint to secure the housing joint;
wherein the band first portion is coupled to a mounting bracket first end;
wherein the band second portion is coupled to a mounting bracket second end opposite the mounting bracket first end; and
wherein the winch is coupled to each of the band first portion and the band second portion and configured to urge the band first portion and the band second portion towards each other to clamp the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint.

2. The apparatus of claim 1 , wherein the housing is a cylindrical housing defining a circular cross-section.

3. The apparatus of claim 2 , wherein the primary clamp and the plurality of secondary clamps are curved to conform to a curvature defined by the cylindrical housing.

4. The apparatus of claim 3 , wherein the mounting bracket includes a curved sidewall, the curved sidewall configured to be positioned on and contact the primary clamp such that the curved sidewall is in continuous contact with the curved primary clamp.

5. The apparatus of claim 1 , further comprising a mounting arm coupled to the mounting bracket, the mounting arm configured to mount the housing on a structure.

6. The apparatus of claim 5 , wherein the primary location is configured to be positioned proximate to the structure when the housing is mounted on the structure.

7. The apparatus of claim 5 , wherein the mounting bracket includes a mounting bracket first portion and a mounting bracket second portion, a first sidewall of the mounting bracket first portion positioned on and contacting the primary clamp, the mounting bracket second portion positioned parallel to a second sidewall of the mounting bracket first portion extending orthogonally from the first sidewall such that a space is defined therebetween, the space configured to receive a mounting arm coupling portion of the mounting arm.

8. The apparatus of claim 7 , further comprising a plurality of fasteners coupling the mounting bracket first portion and the mounting bracket second portion such that mounting arm coupling portion is secured therebetween, the plurality of fasteners passing through mating throughholes defined in the mounting bracket first portion, the mounting arm coupling portion and the mounting bracket second portion.

9. An aftertreatment system, comprising:
a housing including a housing first portion and a housing second portion, the housing first portion including a first joint portion configured to overlap a second joint portion of the housing second portion so as to form a housing joint;
a first aftertreatment component positioned within a first internal volume defined by the housing first portion;
a primary clamp positioned at a primary location of the housing joint, the primary clamp abutting at least a portion of the first joint portion and the second joint portion;
a mounting bracket positioned on and contacting the primary clamp;
a plurality of secondary clamps positioned at secondary locations of the housing joint, each of the plurality of secondary locations different than the primary location, the plurality of secondary clamps abutting at least a portion of the first joint portion and the second joint portion;
a band operatively coupled to the mounting bracket, the band positioned around and contacting each of the plurality of secondary clamps, the band comprising a band first portion and a band second portion, the first and second band portions being formed as separate pieces; and
a winch;
wherein the band is configured to be tightened to urge the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint to secure the housing joint;
wherein the band first portion is coupled to a mounting bracket first end;
wherein the band second portion coupled to a mounting bracket second end opposite the mounting bracket first end; and
wherein the winch is coupled to each of the band first portion and the band second portion and configured to urge the band first portion and the band second portion towards each other to clamp the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint.

10. The aftertreatment system of claim 9 , wherein a second aftertreatment component is positioned within a second internal volume defined by the housing second portion.

11. The aftertreatment system of claim 10 , wherein at least one of the first aftertreatment component and the second aftertreatment component includes a selective catalytic reduction system.

12. The aftertreatment system of claim 9 , wherein the housing is a cylindrical housing defining a circular cross-section, and wherein the primary clamp and the plurality of secondary clamps are curved to conform to a curvature defined by the cylindrical housing.

13. The aftertreatment system of claim 12 , wherein the mounting bracket includes a curved sidewall, the curved sidewall configured to be positioned on and contact the primary clamp such that curved sidewall is in continuous contact with the curved primary clamp.

14. The aftertreatment system of claim 9 , wherein a mounting arm is coupled to the mounting bracket, the mounting arm configured to mount the aftertreatment system on a structure.

15. The aftertreatment system of claim 14 , wherein the primary location is positioned proximate to the structure when the aftertreatment system is mounted on the structure.

16. The aftertreatment system of claim 14 , wherein the mounting bracket includes a mounting bracket first portion and a mounting bracket second portion, a first sidewall of the mounting bracket first portion positioned on and contacting the primary clamp, the mounting bracket second portion positioned parallel to a second sidewall of the mounting bracket first portion extending orthogonally from the first sidewall such that a space is defined therebetween, the space configured to receive a mounting arm coupling portion of the mounting arm.

17. The apparatus of claim 16 , further comprising a plurality of fasteners coupling the mounting bracket first portion and the mounting bracket second portion such that mounting arm coupling portion is secured therebetween, the plurality of fasteners passing through mating throughhol
