Referring now to the drawings and particularly to FIG- URES l, 2 and 3, there is shown means for internally treating a tubular element generally indicated by the numeral 10. The means 10 comprise control structure 12 shown in FIG. 1 of the drawing, the particulars of which form no part of the present invention and which are wellknown in the art and need not, therefore, be further described. Means 14 for supporting and turning a tubular element 16 such as shown in dotted line in FIGURES 4 and 5 are indicated in FIGURE 1 of the drawings and may be of any conventional type such as those disclosed in copending application, Serial Number 755,667, filed August 18, 1958, now Patent Number 2,987,608, owned by the same assignee. A way indicated generally by the numeral 18 is provided including a pair of parallel-spaced tracks 20 and 22 fixed on a plurality of ties 24 and axially aligned with the supporting and turning means 14 but spaced axially therefrom.
There is shown supported upon the tracks 20 and 22 a primary carriage 26, a secondary carriage 28 and a boom 30 connected at one end to primary carriage 26, extending over secondary carriage 28 which supports the same and terminating in a head indicated generally by the numeral 32.
Referring now more particularly to FIGURES 6 and 7 of the drawings, it will be noted that primary carriage 26 consists primarily of fore and aft channel frame members 34 and 36 and side frame members 38 and 40. A front axle 42 is journalled in side frame members 38 and 40 tails of the head construction.
'by virtue of bearing plates 44 and 4d and a pair of front section with the open end facing upwardly to receive the wheels 48 and '50. A rear drive axle 56 is journalled in side frame members 38 and li and has mounted thereon a pair of wheels 57 similar to the ones already described and fixed to the axle in the same manner such that the same need not be redescribed. It should, however, be noted that axle 56 is rotatably journalled in the side frame members whereas the axle 42 may be fixed or rotatably journalled as desired.
Fixed to the primary carriage 26 approximately above the rear drive axle 56 is a gear-reduction unit 58 and a reversible prime mover 60. Reversible prime mover as has an output shaft 62 and gear-reduction unit 58 has an input shaft 64. Output shaft 62 is provided with a pulley as and input shaft 64 is provided with a pulley 68 the pulleys 66 and 68 being in the same vertical plane and thereby aligned to be connected by a belt 71 in driving connection. Gear-reduction unit 58 may be coupled drivingly with the axle by any suitable gear train or chain drive arrangement, many of which are well known in the art and need not be further described in this application;
There is further shown mounted on theprimary carriage 26 a suction pump '72 the same being provided with a driving prime mover 74 a discharge opening to atmosphere 76 and an intake conduit 78. By referring to FIG. 1 again, it may be seen that intake conduit 73 extends forwardly along boom 311, for a purpose which will subsequently be described, to a point adjacent to head 32.
A third prime mover 80 is mounted on primary carriage 26 and provided with an output shaft 82 having a belt receiving pulley 84 mounted thereon capable of receiving a plurality of belts. A rotatable shaft 81; secured to primary carriage 26 by virtue of bearing members 83 and 91 is provided with a belt receiving pulley 92 in the same vertical plane with pulley 84, the pulleys 84 and 92 being drivingly coupled by plurality of belts indicated generally by the numeral 94. It should be further recognized that the bearing members 88 and 911 rotatably journal shaft 86 thereby permitting prime mover 81 to drive shaft 36 through the pulleys 84 and 92 and belts 94. It should be further recognized that support structure is provided generallyindicated by the numeral 26 for supporting vacuum intake conduit 78 at a point spaced from the vacuum pump 72.
It should be noted at this point that shaft 86 extends forwardly along boom and is supported by the boom 31) such that the vacuum intake conduit and the shaft both terminate at the end of the boom 30 adjacent to head 32 for purposes of supplying a source of vacuum and a source of rotating driving power to the head 32 for purposes which will be described as this application proceeds.
. Referring now to FIGURES 3 through 5, head structure 32 is shown in magnified condition to illustrate the de- The fore end of boom 34 is provided with a mounting plate 98 and the aft end of head structure 32 is provided with a complementary mounting plate 100 for purposes of fixing the head structure 32 to the boom 36. It will be noted that the vacuum intake conduit 78 is coupled with one end of a flexible vacuum conduit 102 the other end of which is coupled to a vacuum intake shroud 1114. It will be further noted that the rotatable shaft 86 is coupled by universal coupling 1% to a rotatable shaft 168 on which a brush 111 is fixed. In the ambodiment of FIGURE 3, it will be noted specifically by referring to FIGURE 5 that the head 32 includes a pair of channel iron members 112 and 114 extending from rear mounting plate 190 and terminating in a forward mounting plate 116. A pair of slidable mounting plates only one of which is shown in FIG. 5 and identified by the numeral 118 are provided one at either end of brush'llltl having bearing members extending from the bottom margin thereof one of which is shown in FIG. 5 and identified by the numeral 121) for rotatably journaling the shaft 108. The pair of sliding mounting plates such as indicated by the numeral 118 are arranged to be vertically slidable between the channel members 112 and 114 and each of the sliding mounting plates 118 are provided with angle iron flanges at each side identified by the numerals 123 and 124- the same being located directly below the lower flanges of channel members 112 and 114. A spring 122 is in place between the flanges 123 and 124 and the lower flanges of channel members 112 and 114 and a rod extends through the angle irons 123 and 124 and the lower flanges of channel members 112 and 114, the same being fastened in a common manner such as by nuts 126 above the lower flanges of channel members 112 and 114 and below the angle irons 123 and 124, the structure being shown in FIG. 5 to have solid and dotted line positions which will subsequently be described. It will now be seen that from the construction of the spring biasing arrangement the springs which are indicated by the number 122 will continuously bias brush downwardly as shown in FIGURE 5 toward the dotted line position wherein the brush 110 engages the internal surface of the tubular element 16.
There is further shown a hydraulic, ram 124 which could be operated in either direction by either fluid or air pressure mounted to a fixed mounting member 126 spanning the distance between channel members 112 and 114and. fastened thereto by angle iron flanges and 12'7 which may be fixed to the channel members 112 and 114 by welding or any other suitable fastening means. Hydraulic ram 124- has a piston 128 extending outwardly therefrom and terminating ina coupling 13% engaged with sliding mounting plate 118. As was previously stated, a pair of the rams 124 are present one at each end of the structure to insure the uniform withdrawing of brush 1111 from engagement with element 16. It will now be seen that when the power output ram 124 is operated in one direction the piston 128 will apply power through coupling 130 to the sliding mounting plates 118 at either end of brush 110, withdrawing the brush 110. It is a simple matter then when it is desired to engage the brush 11% with the internal surface of pipe 16 to simply reverse the fluid or air pressure which operates the ram 124 fromthe control structure 12, thereby engaging the brush 111? with the internal surface of pipe 16. It will be further noted wtih reference to FIGURE 3 that the shroud 194 is located between the mounting structure at each end. It will be seen from this construction that loose material which is cleaned from the interior surface of the element of pipe 16 and which may include rust, dirt and other foreign material will'be carried into the vacuum intake shroud both by the force of the vacuum and by the brush, the same being conducted through flexible conduit 1112 and conduit 78 back to the vacuum pump 72 and through the discharge opening 76 to atmosphere. In order to insure that the head structure 32 isproperly disposed Within the element 16 such as shown in FIGURE 5, reference may be had to'FlGURE 4 wherein it can be seen that channel members 112 and 114 are provided with upper and lower spanning plates 134 and 136, respectively, each of which supports a pair of support roller assemblies 138 on the upper plate 134 and 1411 on the lower plate The assemblies 138 and 1411 taken together form a first ring fixed on the channels 112 and 114. A second ring 142 having an inner annular grooved surface for receiving the assemblies 138 and 141) is shown in FEGURE 4, the same having a plurality of rollers 144- which engage with the internal surface of the'pipe or tubular element 16 and which are disposed in a 90 degree offset relationship relative to the rollers of assemblies 138 and 140. The offset relationship is provided to ease the insertion and removal of head 32 by permitting the rollers 144 to rotate in the axial direction and at the same time the rollers 144 do not interfere with rotational movement of the pipe 16 inasmuch as the outer ring 142 will rotate relative to the inner ring formed by the assemblies 138 and 140.
It should be further noted that in order to direct and ease the shifting movement of the brush 110 the channel members 112 and 114 may be provided with a plurality of rollers 148 journalled therein and engageable with the tracks provided by vertically extending angle iron members 150 on sliding mounting plates 118 to prevent sidewise movement of the shifting plate 118 and to ease the vertical motion of the sliding plate 118 under the influence of either ram 124 or springs 122.
Additional guide means may be provided for the insertion of the head assembly 32 into the pipe or element 16 in the form of a mounting bracket 152 which may be fixed to the forwardly facing surface of forward-mounting plate 116. A plurality of grooved rollers 154 may be fixed to mounting bracket152 and extended forwardly therefrom, the same rotatably receiving a plate having a plurality of radially inwardly biased roller assemblies 156. The casters 156 may be provided with a housing member 158 mounted on a rotatable ring 160 which is .received in the grooves of rollers 154. It will be noted that a roller mounting member 162 may be pivotally fixed to housing 158 as at 164, the mounting member 162 being receivable within housing 156 a distance limited by groove 166. The mounting member 162 and housing 158 may be provided with a spring (not shown) biasing withdrawal of the head structure 32 from the element.
It will be further noted that a sleeve 170 extends axially forwardly from mounting bracket 152 relative to the pipe or element 16 and terminates in a flange 172. A second flange 174 is fixed to flange 172 the two flanges being complementary the same being fixed in any suitable manner not shown such as bolts or the like, and inserted between the flanges 172 and 174 is a shield 176 and a shield backing 178 for reasons which will become apparent as this description proceeds. A pair of ears 180 only one of which is shown in FIG. 3 extend forwardly from flange 174 and a spray unit generally indicated by the numeral 182 is adjustably fixed to the ears 180 by suitable means such as a bolt and nut arrangement 184.
Having now described one complete embodiment of pressure.
the present invention, it will be seen that as the reversible prime mover 60 drives the carriage 26, the direction of the drive of the reversible prime mover 60 will determine the direction of the carriage 26 along the tracks 20 and 22 such that the carriage will move toward or away from the tubular element or pipe 16 with which is is aligned. The boom 30 and head 32 which are fixed to carriage 26 will therefore reciprocate with the carriage 26 as will the secondary carriage 28 which merely rides upon the tracks 20 and 22 to support the boom 30. The boom 30 when it travels toward the pipe or element 16 will insert the head 32 therein, the same being centered by virtue of the casters 138 and and the ring 142 and rollers 144 and further by the rollers 154, ring and casters 156. The ram 124 may be activated to move the brush 110 into engagement with the surface of the pipe or element 16 to clean the same, as previously indicated, the dirt and foreign matter removed from the internal surface of the pipe or element 16 being conveyed by the vacuum intake shroud 104 and related structure, as previously described, to a zone removed from the element or pipe 16. Obviously the spray unit 182 would not be operated on the initial pass through the pipe inasmuch as the surface is being cleaned behind the location of the spray unit 182, but when the unit is reciprocated in the opposite direction, the valve structure 198 may be operated by ram 200 to couple the spray head 186 with source 194 so that material may be sprayed on the clean surface of the pipe or element 16. It should be further noted at this point that 194 is a source of material to be sprayed which is under It is, of course, obvious that it may be desirable to clean the surface in a double pass or twice and for this purpose the shield 176 is provided to separate the sprayed material from the area behind the shield 176 which is being cleaned such that the two operations do not interfere with each other. Therefore, on at least the pass wherein the head is moving from right to left as viewed in FIG. 3, the head may be operated to both clean and spray simultaneously.
Various other aspects of the operation may be worthy of note and especially the fact that the universal joint 106 permits the brush 110 to shift between its engaged and disengaged positions while not cutting the brush off from its source of rotated power, namely shaft 86.
It will be further noted that the rings 160 and 142 permit the head to be centered relative to the pipe or element 16 while not in any respect interfering with the rotating of the same by the pipe supporting and turning mechanism 14 or its effect upon the pipe or element 16.
Referring now to FIGURES 8 through 11, a second embodiment of head structure is shown therein which has many of the features of the first embodiment already described, the second embodiment being designated by the general numeral 320. It will be noted that at least at one end of the structure, which is the right hand end as viewed in FIGURE 8, one of the centering rings similar to that already described and having the numeral 160 as shown, the same simply to indicate that both head structure 32 and 320 may be provided with the said mechanism, and it should be further understood that a spray unit 182 may be attached to the right-hand end of the unit as viewed in FIGURE 8 in the same manner as already described.
In the embodiment of FIG. 8, head 320 is provided with a rear mounting plate 322 which is fixed to boom 30 in a manner similar to the first embodiment such as by welding at 324 or by bolts or the like. It can be seen that shaft 86 extending forwardly along the boom has the universal coupling 326 similar to that of the first embodiment illustrated with a rotatable brush shaft 328. Rear mounting plate 322 is connected with a front mounting plate 330 by a series of three angle iron members 332, 334 and 336. It will be further noted that shaft 328 extends through an aperture 339 provided therefor in rear mounting plate 322. A brush shaft plate 3381's also fixed to the angle iron members 332, 336 and 334 adjacent to the rear mounting plate 322. Shaft 328 which is the main brush drive shaft is journalled in the plates 338 and 330, as are two slave brush drive shafts 342, and 344. The shafts 328, 342 and 344 extend through brush shaft plate 338 toward rear mounting plate 322. Each of the shafts 328, 344 and 342 have respectively mounted thereon in the same perpendicular plane at the end of the shafts intermediate brush shaft plate 338 and rear mounting plate 322, sprockets respectively enumerated 346, 348 and 358. The sprockets 3'46, 348 and 350 are drivingly interconnected by a chain 352 such that driving power imparted to shaft 328 by shaft 86 may be transferred through the chain 352 to sprockets 348 and 358 and thence to shafts 344 and 342 respectively. On the facingsides of shaft plates 338 and 330 and adjacent thereto are pivotally mounted brush supporting and positioning plates 354, 356 and 358. It is to be understood that there are duplicate plates 354, 356 and 358 at either end of the brush shafts. The brushes are designated generally by the numbers 360, 362 and 364. Shaft supporting and positioning plates 354, 35 6 and 358 being pivotally mounted on respective shafts 344, 342 and 328 have journalled' rotatably therein brush shafts 366, 368 and 370 respectively. Brush shafts 366, 368 and 378 haveibrush shafts 3%, 360 and 362 respectively mounted thereon and the driving power from the shafts 328', 344 and 34-2 may be transferred to the shafts 366, 368 and 378 by means of'a chain and sprocket connection between thepairs of shafts 344 and 366, 342 and 368 and 328 and 378. The latter are not shown inasmuch as such means of transferring driving power is well known in the A pair of spaced parallel discs 372 and 374 are shown in FIGURE 8 mounted on a central shaft 376 which is rotatably journaled in brush shaft plate 338 and front mounting plate 330. The discs 372 and 374 are respectively positioned between shaft supporting and positioning plates 356, 358 and 354 and the brushes 368, 362 and 364cm opposing ends of the brush shafts. Discs 372 and 374 are provided with link assemblies 378, 380 and 382 respectively com necting the disc 372 to shaft supporting and positioning plates 35%, 358 and 354. A hydraulic ram 384 is shown fixed to angle iron member 334 by coupling 385, the ram 384 having a piston 388 pivotally coupled with a pivot arm 398 keyed to shaft 376 as-indicated in FIG- URE 11 to be fixed to shaft 376. It is obvious that operation of the ram 384 will move the piston 388 and thereby the pivot arm 3% to rotate or more correctly to oscillate the shaft 376 which in turn will oscillate the discs 372 and 374. Oscillation of discs 372 and 374 will move the pivot links 378, 380 and 382 each of which is respectively pivotally coupled with an ear 392 of shaft supporting and positioning plate 356 and ear 394 of shaft supporting and positioning plate 358 and an car 396 of shaft supporting and positioning plate 354. The shaft supporting and positioning plates 354, 356 and 358 will then be oscillated about their rotatable connection with shafts 344, 342 and 328 to move the brushes into and away from engagement with the interior surface of the pipe or element 16. It should be noted at this point, and is well known in the art, that the ram 384 may be openated from control structure 12 remotely positioned therefrom to move the brushes in either the engagement or disengagement direction.
It is, of course, obvious that the head structure 328;
with the spray nozzle and suction apparatus shown in the embodiment of FIGURES 3 through 5 and placing the same on the end of the boom 30 in place of the embodiment of FIGURES 3 through 5 will provide a head structure which will function in substantially the manner already described with the exception of the positioning of the brushes which will be done by the hydraulic ram 384 in the manner already described.
It should be further noted that the tracks and 22 may be provided with stops 2% and 288 spaced on opposite sides of the secondary carriage 28 such that the reciprocable movement of the secondary carriage 28 is limited and that the secondary carriage 28 may be provided with an idler roller 210 engageable with the bottom of boom 30 which is generally triangular in shape in the preferred embodiment such that when the carriage is stopped by either of the stops 206 or 288 the boom may continue to reciprocate by rolling on the roller 210.
