' PIPE BOOM SUPPORTING APPARATUS Filed Oct. 18, 1950 2 Sheets-Sheet 2 INVENTOR. J.M. LEWIS ATTORNEY Patented Nov. 3, 1953 PIPE BOOM SUPPORTING APPARATUS Jesse M. Lewis, Tulsa, Okla., assignor to Williams Brothers Company, Tulsa, Okla., a corporation of Nevada Application October 18, 1950, Serial No. 190,855 8 Claims. (01. 118-506) This invention relates to a boom supporting apparatus, and more particularly, but not by way of limitation, to an apparatus for supporting a boom utilized in the internal treatment of tubular objects such as pipes and the like.
In the usual pipe processing yard utilized for the purpose of internally treating pipes, or similar cylindrical objects, three principal steps are utilized: internally cleaning the pipe; spraying priming material onto the inner surface of the pipe; and internally coating the pipe with a bituminous or asphaltic material. The cleaning is usually accomplished by inserting a rotating cleaning head through the pipe while retaining the pipe in a stationary position. The cleaning head is carried on the outer end of a horizontally disposed boom, and the boom is supported at its outer end by a suitable power operated car. The power car is adapted to rotate the boom and cleaning head as Well as move the cleaning head through the pipe.
v The priming is accomplished by moving a spray head, adapted to spray the priming material in a 360 degree pattern through the pipe. Again the pipe is held stationary, and the spray head is moved through the pipe by the use of a horizontally disposed boom. The boom is supported by a power car at its outer end, and suitable carriages spaced along the length of the boom which are adapted to move in a stationary runway. At least one of the carriages rolls along the inner surface of the pipe when'the spray head is moved therethrough,
The internal coating is usually accomplished by inserting a suitable V-shaped cantilevered trough in a joint of pipe. The trough is filled with the coating material and the pipe is' placed in rotation. As the pipe rotates, the trough is tilted to spill the coating material onto the inner surface of the pipe. The rotary motion of the pipe tends to spread the coating material into a relatively even and uninterrupted coat on the It will be apparent that the length of the .pipe that may be treated, particularly in the internal coating portion of the treatment, is very limited. The cantilevered troughmust be retained in a truly horizontal position to obtain the desired results, and since the coating material carried by the trough is relatively heavy, the trough cannot be of extended length.
The present invention contemplates a stationary boom over which a pipe may be telescoped, as contrasted with the movable booms and troughs presently utilized. The boom is suspended in a horizontal position by use of suitable hangers and hooks in such a manner that when a pipe is telescoped over the boom, the pipe will disengage the hangers and allow the boom to be supported on the inner surface of the pipe by use of suitable rollers or casters. The pipe is adapted to be moved into a telescoping position over the boom by suitable mobile power cars usually moved under the supported boom. Upon removal of the pipe from the boom, the hangers will engage hooks on the boom to again suspend the boom in a horizontal position. The boom may carry a cleaning head or spray head on the outer end thereof in order to perform any one of the various treating operations. The boom may be of a suitable length to accommodate multiple joints of pipe.
An important object of this invention is to provide a novel apparatus for supporting a boom used in the internal treatment of pipes.
Another object of this invention is to provide a boom supporting apparatus whereby a plurality of pipe joints may be treated in one operation.
Another object of this invention is to provide apparatus for supporting a pipe boom whereby ,a pipe may be telescoped over the boom without interference with the supporting structure.
i A further object of this invention is to provide a boom supporting apparatus whereby a pipe being telescoped over the boom will automatically disengage the boom supporting mechanism and permit the boom to be supported by the pipe.
A still further object of this invention is to 7 provide apparatus for supporting and maintaining a boom in a horizontal position. Another object of this invention is to provide a simple and inexpensive boom supportingapparatus; Other objects and advantages of the invention will be evident from the following detail description, read in conjunction with the accompanying drawings, which illustrate my invention.
In the drawings: ,i- Figure l is a perspective view of the novel boom and the supporting apparatus therefor.
Figure 2 is a 'detail of a hanger and hook device for supporting the boom.
Figure 3 is a cross sectional view of the boom illustrating a pipe, in dotted lines, being tele-- scoped over the boom. Referring to the drawings in detail, reference character 2 designates a novel boom having a suitable spray head 4 secured to an outer end 6 thereof. The opposite end 8 of the boom .2 "is anchored by a plurality of upstanding braces l0;
- 3 The boom 2 extends through a plurality of A- frames I2 uniformly spaced along the length thereof.
An adapter plate I4 (Fig. 2) is secured to the lower side of the top member l6 of each A-irame I2 in line with the longitudinal center line (not shown) of the boom 2. A bracket l8, having a pair of depending arms straddling the center line of the boom 2, is secured by a pair of bolts 22 to each adapter plate I4. Aligned apertures are provided in the lower ends of the arms 20 to rotatably receive the opposite endsof astud: 2G. The pin 26 is secured in the apertures '21 by suitable cotter pins 28 or the like. A- pair--of v transverse apertures 30 are also provided in the pin 26 symmetric with the center line of the boom 2. A downwardly extending u shaped hanger 32 has its free ends 34 extending through the apertures 30 and secured to the pin- 26 by the threaded nuts 36. The lower loop end 38 of each hanger 32 is adapted to engage a hook 40.ri'gidly Secu'redto the upper side of the boom. 2, in line with the longitudinal center line thereof. The hooks M), are provided v.WithEan open slotAl extendingtoward the inner end 8 ofthe boom 2 for purposes as will be hereinaftersetforth.
A .pair otpaster mounting plates 42.,fiFig. 3) are secured tothe underside of the. boom 2.in longitudinal spaced relation to each A-jrame, J2.
Asuitable. casterfit is secured to each mounting platen by-a-plurality of bolts 46. ,Each of the casters, 4lareprovidedwith caster wheels 48 contactingthe innersuriac e of the pipe 50. (shown in dott a ,iines.m.pi 3) when the pipe is telescoped;- over the boom 2 as will be hereinafter set forth. Operation operation, the boom'z is' normally "supported by the upstanding A -frames l2 through the medium of the pivotal hangers 32 and hooks 40. As a-"pi-pe 5D (Fig. 3 which is movably supported by suitablemobile power cars, not shown) is telescoped over the boom 2, the leadingend (not shown) of the pipe strikes the hangers32 to disengage the hangers from the hooks 40 and'svving t h s r up ar 9 1 f f r yfjmq smentof the pipe -Previous to the disengagement or each hangerfl; however, the proximately disposed caster wheels 4'8 contact the inner su fee of the pipe 50 to support the boom 2. The
caster-wheels 48 are preferably disposed'slig'htly onto the-boom2, coating materialmaybefsupplied to the spray head 4 through the boom 2. The pipe 50- may then. be translated off. of "the boom 2 andsimultaneouslyrotated to apply the coating.materialinternallyion. the pipe 50. in a helical path. As the pipeill .is rotated, thecasters 44 automatic-ally assume they position shown .by the right. handcasters M in Fig.3 to permit, free rotation of the pipe 50. In the ,eventja 360 degree type of spray :head ,(not shown) such asjthose used in priming operations is. provided on the cnd 6 of the boom 2,.the pipe 50.may,be, simply translated off. of the;.boom .2. Asthe pipe 50, moves past each hook 411, the respective hanger 32 therefore is then permitted to swing downwardly by gravity into engagement therewith to support the boom 2. It will be noted that as each hanger 32 is engaged, the respective casters M will still be in a raised position in the pipe 50 to facilitate the engagement of the hangers 32 and hooks 40 The braces IQ preclude longitudinal movement of the. boom} during the tre'a'ting operations, as well as support the rear end 8 of the boom. I It will be readily appreciated that the boom 2 may efliciently be utilized to support a cleaning heaifinot shownr instead of the spray head I if desired. Theboom 2 may then be used as a housing. for the cleaning head shaft (not shown) rotated any suitable manner (not shown) The length 0'! the hangers 32 may be readily adjusted, by themats 36 to support the boom 2 in either a truly horizontal position or at an angle to the horizontal as desired, and a sufiicient number of A-frames l2 may be provided to assureno sagging or deformation of the boom 2. From. the foregoing it is apparent that the present invention provides a novel apparatus. for supporting .a boom whereby a pipe or the like may be readily telescoped over the boom without interference with supporting structure. The boom may be disposed at any desired angle and will not sagor bend, either before'or after apipe is telescopedthereon. The boom may beer "a suitable length to accommodate a plurality of pipe joints.
