[0024] The accompanying drawings mentioned above are not necessarily drawn to scale, and it should be understood that they provide schematic diagrams of the invention and illustrations of the principles involved. For ease of explanation and understanding, some features of the tube support clamping assembly described in the drawings have been enlarged or modified relative to other features. The same reference numerals are used in the drawings for similar or identical parts and features shown in various alternative embodiments. The tube support clamping assembly disclosed herein will have a construction and components partially determined by the intended application and environment in which it is used. Detailed Implementation

[0025] The present application can be implemented in various forms. Figure 1 An embodiment of a tube support installation assembly 10 is shown. In the illustrated embodiment, components of the tube support installation assembly 10 are mounted on top of a workbench 12. It should be understood that components of the tube support installation assembly 10 need not all be mounted to a single workbench 12, and one or more components of the tube support installation assembly 10 can be positioned away from the remainder of the tube support installation assembly 10.

[0026] For convenience, the terms "upper," "lower," "top," "bottom" are used herein to distinguish between upper and lower ends of the tube support installation assembly 10, as well as particular components of the assembly. It should be understood that "upper," "lower," "top," "bottom" are used for ease of description and understanding only, and the above terms are not intended to limit the possible spatial orientation of the tube support installation assembly or its components during assembly or use.

[0027] The term "substantially" as used herein means a majority or nearly the same as within reasonable constraints of business engineering goals, costs, manufacturing tolerances, and capabilities in the field of tube support installation. Similarly, the term "approximately" as used herein means close to or about a particular value, within reasonable constraints of business engineering goals, costs, manufacturing tolerances, and capabilities in the field of tube support installation.

[0028] The tube support installation assembly 10 can include an alignment bar 14, as Figures 2-4 shown, during installation of a tube support on a finned tube 16, the finned heat exchanger tube or finned tube 16 can be seated on the alignment bar 14. A stop block 18 can be movably secured to the alignment bar 14, and can be used to properly position the finned tube 16 along the alignment bar 14. As Figures 2-4 shown, a spacer bar 20 can extend along the alignment bar 14, and can be received in the finned tube 16 during at least a portion of the installation of a support bar 21 (see below Figures 11-14 ) on the finned tube 16.

[0029] A pressing assembly 22 can be positioned along the alignment bar 14, and can be used to flatten fins on the finned tube 16, as described in greater detail below. A gauge assembly 24 can be secured to the alignment bar 14, and can be used to measure the flattened portion of the fins of the finned tube 16. A tube support clamping assembly 26 can be positioned on the workbench 12, and can be configured to clamp a support bar around the flattened portion of the fins of the finned tube 16, as described in greater detail below.

[0030] Each of the stop block 18, pressing assembly 22, gauge assembly 24, and tube support clamping assembly 26 can be configured as a separate workstation on which different stages of installing the support bar 21 onto the finned tube 16 can be performed. As mentioned above, each of these components or workstations can be positioned on the worktable 12; however, it should be understood that one or more workstations can be positioned away from the worktable 12 and still function as intended in installing the support bar 21 onto the finned tube 16.

[0031] like Figures 2-4 As shown, the finned tube 16 may include a tube portion 28 having a first open end 30 and a second open end (not shown), and a plurality of fins 32 fixed to the outer surface of the tube portion 28. The first open end 30 may be substantially cylindrical, while the tube portion 28 may be more flattened, having an elliptical or racetrack shape. Figures 2-3 As shown, in order to begin installing the support bar 21 onto the finned tube 16, the first end 34 of the spacer bar 20 is inserted into the first open end 30 of the finned tube 16, and then the finned tube is slid along the alignment rod 14. The finned tube 16 then travels along the alignment rod 14 and through the opening 36 of the pressing assembly 32, through which the alignment rod 14 extends.

[0032] The finned tube 16 can travel along the alignment rod 14 until a selected portion of the finned tube 16 is positioned at the center of the pressing assembly 22, where a portion of the fin 32 can be flattened to accommodate the support bar 21. In some embodiments, such as Figure 1 and Figure 4 As shown, the stop block 18 can move along the alignment rod 14 until the left edge 38 of the stop block 18 is located at a desired distance D from the center of the pressing assembly 22. Figure 4 As shown, the scale 39 can be positioned along the alignment rod 14, allowing the user to accurately measure the distance between the left edge 38 of the stop block 18 and the center of the pressing assembly 22. In the illustrated embodiment, the scale 39 has measurements in inches; however, it should be understood that any unit of measurement can be used on the scale 39.

[0033] The stop block 18 can then be secured to the alignment rod 14 with one or more fasteners such as bolts 40. It should be understood that any type of fastener can be used to releasably secure the stop block 18 to the alignment rod 14, and other suitable fasteners will become apparent to those skilled in the art in light of the benefits of this disclosure.

[0034] Once the finned tube 16 is in the proper position relative to the pressing assembly 22, the first set of fins 32 42 on the top or first surface 44 of the finned tube 16 and the second set of fins 32 46 on the bottom or second surface 48 of the finned tube 16 can be compressed or flattened by the pressing assembly 22 to form the flattened portion 49 of the finned tube 16.

[0035] like Figures 5-7 As shown, the pressing assembly 22 may include a housing 50 defining an opening 36. A handle 52 is rotatably supported on the housing 50 via a shaft 54. A pinion (not visible) at one end of the shaft 54 ​​engages a rack 56, such that rotation of the handle 52 about the shaft 54 ​​causes vertical movement of the rack 56. A top block 58 of the pressing assembly 22 is mounted at the bottom of the rack 56, and a bottom block 60 of the pressing assembly is mounted to the housing 50 below the top block 58.

[0036] When the user grasps the top portion 62 of the handle 52 and rotates it forward about the axis 54, the rack 56 moves downward, causing the top block 58 to move downward in the direction of arrow A, compressing or flattening the first group 42 fins 32. Simultaneously, as the top block 58 presses downward onto the first group 42 fins 32, the second group 46 fins 32 are forced downward and compressed or flattened by the bottom block 60 to form the flattened portion 49 of the finned tube 16 with height F. Figure 8 The finned tube 16 is shown, in which the first group 42 and the second group 46 fins 32 are in a flattened state.

[0037] like Figure 5 As shown, the stop 64 can be mounted to the housing 50 and positioned to engage the top block 58 and prevent it from moving downwards at the desired location. The positioning of the spacer 20 within the tube portion 28 of the finned tube 16 helps prevent the tube portion 28 from being compressed and flattened as the top block 58 moves downwards.

[0038] like Figure 9As shown, the gauge assembly 24 can include a first plate 66 that can be secured to the alignment bar 14 by fasteners such as gauge bolts 68. It should be appreciated that the first plate 66 can be secured to the alignment bar 14 by any type of fastener, and other suitable fasteners will become apparent to those of ordinary skill in the art with the benefit of this disclosure. Furthermore, it should be appreciated that the gauge assembly 24 need not be secured to the alignment bar 14 and can be located at any desired location away from the alignment bar 14. A second plate 70 can be vertically spaced above the first plate 66, defining a first gap 72 having a first height H1 between the first plate 66 and the second plate 70. A first spacer 74 can be positioned between the first plate 66 and the second plate 70. A third plate 76 can be vertically spaced above the second plate 70, defining a second gap 78 having a second height H2 that is less than the height H1 between the second plate 70 and the third plate 76. A second spacer 80 can be positioned between the second plate 70 and the third plate 76. The first plate 66, the first spacer 74, the second plate 70, the second spacer 80, and the third plate 76 can all be secured to one another by one or more fasteners such as plate bolts 82. It should be appreciated that the first plate 66, the first spacer 74, the second plate 70, the second spacer 80, and the third plate 76 can be secured together by any type of fastener, and other suitable fasteners will become apparent to those of ordinary skill in the art with the benefit of this disclosure.

[0039] The gauge assembly 24 can be used to determine whether the first set 42 and the second set 46 of fins 32 have been flattened by an appropriate amount such that the height F of the flattened portion 49 is sized to accommodate the strut 21. To use the gauge assembly 24, as Figure 10 shown, the flattened portion 49 of the finned tube 26 can be alternately inserted into each of the first gap 72 and the second gap 78. The height H1 of the first gap 72 and the height H2 of the second gap 78 can be sized to ensure that the flattened portion 49 is sized to accommodate the strut 21. When the height F of the flattened portion 49 is small enough that the flattened portion 49 can be slid into the first gap 72, as Figure 10 shown, but too large to be slid into the second gap 78, the user can be confident that the strut 21 will fit around the flattened portion 49.

[0040] Figures 11-14The diagram illustrates mounting a strut 21 onto the flattened portion 49 of a finned tube 16 using a tube strut clamping assembly 26. The strut 21 may include a top wall 84, a bottom wall 86, a rear wall 88, and a front wall 90, the front wall 90 having a bottom edge 92 pivotally connected to the bottom wall 86 and a free top edge 94. Initially, the strut 21 may be positioned in a recess 96 formed in a clamping housing 98 of the tube strut clamping assembly 26. A protrusion 100 may be formed on the rear wall 88 and may be received in a groove 102 formed in the rear surface 104 of the recess 96 to help retain the strut 21 within the recess 96.

[0041] The tube support clamping assembly 26 may include a clamping arm 106, which is pivotally connected to the clamping housing 98 via an arm shaft 108. A pair of link arms 110 may be pivotally connected at their first end 112 to a first arm shaft 114 supported by the clamping arm 106, and at their second end 116 to a second arm shaft 118 supported by a clamping block 120. The clamping block 120 may be pivotally connected to the clamping housing 98 via a block shaft 122.

[0042] In order to install the support bar 21 on the finned tube 16, as Figure 12 As shown, the flattened portion 49 of the finned tube 16 is inserted into the support slat 21 between the top wall 84 and the bottom wall 86, wherein the front wall is tilted forward away from the bottom wall 86. When the flattened portion 49 is properly positioned within the support slat 21, the clamping arm 106 can rotate rearward about the arm axis 108, causing the connecting arm 110 to pull the clamping block 120 and pivot it rearward about the block axis 122. As the clamping block 120 pivots rearward, it engages the front wall 90 of the support slat 21 and forces the front wall rearward, so that the lip 124 located at the free top edge 94 of the front wall is forced to engage with the groove 126 formed in the top wall 84 (see...). Figure 11 ), thereby enclosing the support bar 21 around the flattened portion 49 of the finned tube 16.

[0043] In the illustrated embodiment, the strut clamping assembly is mounted on and attached to the worktable 12. It should be understood that the strut clamping assembly 24 does not need to be mounted on or attached to the worktable 12 and can be located at any desired location away from the worktable 12.
