Retractable rotating hose apparatus

Abstract

A retractable rotating hose device for rotating and helically thrusting a high pressure hose and biased nozzle into a pipe for the purpose of cleaning the interior surface of the pipe. The retractable rotating hose device is powered by converting linear torque from a rotating high pressure hose into linear thrust, forcing the high pressure hose and biased nozzle into the pipe, where the high pressure hose and biased nozzle travel through the pipe in a helical manner. The retractable rotating hose device remains generally stationary during the pipe cleaning operation and includes a spring-operated spool which automatically rewinds the high pressure hose at the termination of pipe cleaning operations. The present invention more effeciently cleans conduit, pipe and other tubular members, by constantly positioning the biased nozzle against the interior surface of the pipe and avoiding the "streaking" effect left by prior art nozzles. The helical pitch of the rotating high pressure hose, speed and direction of travel of the high pressure hose are controlled through the alignment of the drive wheels in the rotary hose drive.

Description

FIELD OF THE INVENTION

The present invention relates generally to cleaning the internal surface of conduits or pipes. Specifically, the present invention relates to a retractable rotating hose apparatus for thrusting a high pressure, rotating, fluid bearing hose and cleaning nozzle into a pipe to remove tough, hard or brittle deposits or coatings from the interior surface of the pipe.

BACKGROUND OF THE INVENTION

Effectively and effeciently cleaning plugged or partially plugged conduit, pipe or assorted tubular members continues to be a major problem. Keeping industrial, commercial and residential piping clean and avoiding the problem of "streaking" or leaving an uncleaned or partially cleaned path is an ongoing concern which costs hundreds of millions of dollars annually in this country alone. Plugged residential piping is a nuisance and an inconvenience to the home dweller and can become costly if improperly handled. Plugged commercial and industrial piping is more than a nuisance or an inconvenience. Plugged commercial and industrial piping is costly in terms of lost production and lost profits to the company, lost or reduced wages to the workers and the costly expense of cleaning and maintaining the piping.

Of primary concern in the present invention is to provide a more efficient, less expensive, safer and easier to use system to clean and maintain the internal surface of industrial, commercial and residential piping.

It is, therefore, a feature of the present invention to provide a cleaning operation which is automatic and thereby reduces the cleaning time compared to prior manual cleaning techniques.

A feature of the present invention is to provide an independent set of controls for forward or backward speed, and rotational speed to control the size particles removed from the internal surface of the piping.

Another feature of the present invention is to provide a safer system of cleaning the interior surface of piping, in that the operator need not be in close proximity to the pipe opening or the rotating hose.

Another feature of the present invention is to provide a hydraulic, or other non-internal combustion, powered rotating device which can be safely used in hazardous or explosive environments, where an internal combustion engine could not safely operate.

Yet another feature of the present invention is to provide rotating, helical or screw-like insertion of the high pressure hose and biased cleaning nozzle into the pipe, which greatly reduces the amount of streaking on the interior surface of the piping.

Yet another feature of the present invention is to provide an internal pipe cleaning system which is light and portable permitting its use in many small, elevated or lowered work areas.

Still another feature of the present invention is to provide an internal pipe cleaning apparatus which can be used in piping of wide ranging diameters, with comparatively small water blast equipment.

Yet further, an additional feature of the present invention is to provide a safe internal pipe cleaning apparatus whereby, should the high pressure hose burst while inside the pipe or the biased cleaning nozzle become separated from the high pressure hose, the hose will not uncontrollably retreat from the piping.

Still another feature of the present invention is to convert the torque from the rotating hose into linear thrust, to thrust the high pressure hose forward or backward, and to use the same linear thrust to control the speed with which the high pressure hose and biased cleaning nozzle are inserted into the pipe.

Yet another feature of the present invention is to control the helical pitch at which the high pressure hose and biased cleaning nozzle are inserted into a pipe, to provide more efficient cleaning.

Another feature of the present invention is to employ a biased cleaning nozzle which is designed to press itself against the interior surface of the pipe to more effectively clean the interior surface and not attempt to position itself centrally within the pipe as do prior art nozzles.

Yet still another feature of the present invention is to provide an apparatus for cleaning the interior surfaces of pipe more effectively and more efficiently than other currently known devices.

Another feature of the present invention is to provide an apparatus for rotating a high pressure hose to be thrusted into a pipe for the purpose of cleaning the interior pipe surface, where the hose rotation apparatus remains relatively stationary during the thrusting of the high pressure hose and biased cleaning nozzle.

Still another feature of the present invention is to provide an apparatus for rotating a high pressure hose where the hose rotation apparatus does not require a linear path-way to move back and forth on, and where said hose rotation device may be vertically raised or lowered and contains a finite length of high pressure hose which is inserted into the pipe to effectively clean the interior surfaces of pipe.

Yet another feature of the present invention is to provide an apparatus for rotating a high pressure hose where the hose rotation apparatus includes a retractable or spring-operated spool which automatically retrieves the high pressure hose from the pipe after the cleaning is completed, obviating the need for the operator to manually pull the high pressure hose from the pipe.

Additional features and advantages of the invention will be set forth in part in the description which follows, and in part will become apparent from the description, or maybe learned by practice of the invention. The features and advantages of the invention maybe realized by means of the combinations and steps particularly pointed out in the appended claims.

SUMMARY OF THE INVENTION

To achieve the foregoing objects, features, and advantages and in accordance with the purpose of the invention as embodied and broadly described herein, a retractable rotating hose device is provided for more effectively and effeciently cleaning the interior surface of industrial, commercial and residential piping.

The retractable rotating hose device rotates a high pressure hose and a biased cleaning nozzle using a flex lance drive. The flex lance drive is a rotating gyroscope yoke framework including a retractable spring-biased spool containing a finite amount of high pressure hose. The flex lance drive rotates and feed high pressure hose to the rotary hose drive while remaining in a generally stationary, non-rolling position. This is advantageous since the rotary union drive must roll back and forth, a distance of up to 50 feet, in order to add new sections of high pressure hose to the conduit. Moreover, the flex lance drive includes a retractable spring-biased spool which automatically reels back the high pressure hose after the cleaning is completed. When using the rotary union drive, the operator must manually pull the hose out of the pipe after termination of the pipe cleaning operations.

A flex lance drive can be used to replace the rotary union drive, where the characteristics of the flex lance drive are preferred over the rotary union drive. The flex lance drive may often be used where a rotary union drive can not physically be used. The rotation of the hose inside of the rotary hose drive creates torque which overcomes the compression forces of the spring-operated spool and unwinds high pressure hose from the spool. The flex lance drive is better suited for small, elevated or lowered positioning where the retractable rotating hose device must be positioned in a confined area or on a small platform.

The biased cleaning nozzle rotates through the interior portion of the pipe and advances in a helical path. The advancement of the biased cleaning nozzle eliminates the streaking left from known pipe cleaning systems.

The present invention removes deposits, debris and coatings from the interior surfaces of concrete, PVC, steel and many other pipe materials with minimum damage to the pipe itself. In particular, the present invention is especially useful in cleaning heat exchanger tubes in areas with limited access. The present invention can negotiate bends in most piping systems. Flexible high pressure hose withstanding pressures of 60,000 PSI can be used in pipe diameters ranging from 0.4 inches to 240 inches. The present invention is comparatively light and portable allowing for its use in many small, elevated or lowered work areas. The rotational speed rotational direction, pressure and fluid flow are remotely and independently controllable far removed from the entrance to the pipe and the rotating hose, providing additional safety to the operator.

A rotating, high pressure hose having a biased cleaning nozzle is inserted helically into the pipe at an angle ranging between the longitudinal axis of the tubular member and the lateral axis of the tubular member. By entering the pipe at a non-parallel angle relative to the longitudinal axis of the pipe, the biased cleaning nozzle and high pressure hose are forced to enter the pipe in a helical manner and maintain their travel through the pipe in a helical manner. The jetting forces from the biased nozzle, keep the nozzle pressed against the interior surface of the pipe and provide for the elimination of streaking and less damage to the interior surface of the pipe. By using a high pressure hose and biased cleaning nozzle in a rotating, helical manner, the time required to clean interior pipe surfaces is greatly reduced from methods and apparatus currently used, and with better results.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the present preferred embodiments of the invention as described in the accompanying drawings.

FIG. 1 is a perspective view of the rotating hose apparatus 10, including an Aqua-Dyne D40277-42 portable hydraulic power unit 12, an Aqua-Dyne C-Series high pressure pump 14, a rolling platform 16, a rotary hose drive 18, a high pressure hose 20, a bias cleaning nozzle 22, a pipe 24 and scale, coatings, brittle or hard deposits, or other debris 26 which accumulates on the interior surface of the pipe 24.

FIG. 2 illustrates a cross-sectional side view of the rolling platform 16. The rolling platform 16 employs a control panel 27 to control a high pressure water inlet 28, a rotary union drive 30, a connection hose 32 between an inlet 28 and a rotary union drive 30, a swivel joint 34 to allow the high pressure hose 20 to rotate, a power source 36 to drive a swivel joint 34, a first sprocket 38 which attaches to a drive shaft 40 protruding from a power source 36, a second sprocket 42 which attaches to the swivel joint 34, and a drive chain 44 which engages both sprockets 38, 42 to transfer energy from the power source 36 to the swivel joint 34. A first incomming hydraulic hose 46 brings high pressure hydraulic fluid from the hydraulic power unit 12, to provide energy to the power source 36. A second outgoing hydraulic hose 48 returns hydraulic fluid to the hydraulic power unit 12 to be reused.

Referring to FIGS. 1 and 2, the high pressure hose inlet 28 is engaged to high pressure pump 14 via a high pressure hose 50 which is a standard high pressure hose. The high pressure hose 20 is constructed of a plurality of hose segments, in which the first joint of the high pressure hose 29 has it's female end threadably connected to a swivel joint 34 and the male end of the high pressure hose 20 is threadably connected to the bias nozzle 22. The high pressure hose 20 is centrally engaged with the rotary hose drive 18 and depends through the aperture 52 of the rotary hose drive 18, where the nozzle 22 is inserted into the pipe 24. As the swivel joint 34 begins to rotate the high pressure hose 20 in association with the transfer of energy from the hydraulic power unit 12 to the power source 36, the high pressure hose 20 generates rotary torque which is transfered into linear hose thrust in the rotary hose drive 18. As the rotary hose drive 18 translates the linear hose thrust, the high pressure hose 20 is thrust into the pipe 24 and the rolling platform 16 is drawn toward the rotary hose drive 18. When the rolling platform 16 is within feet, for example 5 to 10 feet, of the rotary hose drive 18, the operator disengages the hydraulic power unit 12, thereby interrupting the power supplied to the swivel joint 34. The female end of the high pressure hose 20 is then disengaged from the swivel joint 34 and a new segment of high pressure hose 20 is added. The male end of the new segment of high pressure hose 20 is threadably connected to the female end of existing portion of the high pressure hose 20. The female end of the new segment of the high pressure hose 20 is threadably connected to the swivel joint 34. Once the new segment of high pressure hose 20 has been added, the rolling platform 16 is rolled back, in the opposite direction from the rotary hose drive 18, taking the slack out of the newly added portion of high pressure hose 20. Having taken out the slack of the newly added portion of high pressure hose 20, the hydraulic power unit 12 is engaged with the power source 36, whereupon the swivel joint 34 rotates the newly added portion of high pressure hose 20 and all prior engaged segments of high pressure hose 20. Numerous sections of the high pressure hose 20 may be added by following the aforementioned procedure. The rolling platform 16 is constantly being drawn to the rotary hose drive 18, when the high pressure hose 20 is both rotating and being thrust into the pipe 24.

FIG. 3 is a cross-sectional end view of the rolling platform 16. The rolling platform 16 further employs a plurality of casters 54, a cover 56 and a plurality of latches 58 to secure the cover 56 to the platform 16.

FIG. 4 is a cross-sectional view of the rotary hose drive 18. A plurality of drive wheels 60 are centrally located within the frame 62 of rotary hose drive 18. Drive wheels 60 are pivotally pinned in caster frames 64 using nut, bolt and washer assemblies 66. The rotary hose drive frame 62 is a two piece frame, horizontally divided and hinged at nut, bolt and washer assembly 68. An adjustable spring loaded clamp arm 71 secures the opening 72 in rotary hose drive frame 62. Drive wheels 60 are engagedly affixed to high pressure hose 20 and directly transform the rotary hose torque generated by swivel joint 34 and transferred via high pressure hose 20, into linear thrust to propel the high pressure hose 20 into pipe 24. The caster frames 64 can pivot to align drive wheels 60 to position high pressure hose 20 to enter pipe 24 at a variety of pitch angles to cause high pressure hose 20 to travel through pipe 24 in a helical manner. The caster frames 64 can be pivoted by loosening adjustment bolts 70 and turning the caster frames 64 in the desired direction and then retightening adjustment bolts 70. A plurality of pin rollers 67 are utilized to prevent adjusting bolts 70 from rotating and becoming loose. A plurality of spring plungers 69 are incorporated in the internal caster housing 64 to align a spring loaded pin 65 with a pre-drilled slot 63, for greater ease in adjusting the pitch angle of drive wheels 60. The amount of torque generated by swivel joint 34 and transferred via high pressure hose 20 directly controls the speed at which the high pressure hose 20 enters the pipe 24. The adjustable spring loaded clamp arm 72 allows for clamp adjustments to suit variations in high pressure hose 20 size and interior surface conditions in the pipe 24. The adjustable spring loaded clamp arm 72 employs a pull clamp handle 74; latch tensioner 76; a shaft 78, being pivoted at one end and the other end being threaded; a compression spring 80, to maintain tension on the clamp arm 72; and adjustment nut 82 to increase or decrease the tension on spring 80, by threadably engaging the threaded end of shaft 78.

In FIG. 5, one embodiment of the biased nozzle 22 is depicted. Nozzle 22 is a uniquely shaped nozzle, specially designed to be used with the rotating hose device 10 and is generally of a cylindrical shape having a combination of flat, beveled, pointed or rounded head members 106, 114, 120, 134, as depicted in FIG. 9, FIG. 10, FIG. 11 and FIG. 12. As depicted in FIG. 5, nozzle 22 has three or more jets 100, 102, 104. A plurality of three or more jets 100, 102, 104, positioned as shown in FIG. 5, FIG. 6, FIG. 7 and FIG. 8, ensures that the nozzle 22 will not be centrally located within the pipe 24, and that nozzle 22 is pressed against the interior wall of pipe 24. By constantly pressing the nozzle 22 against the interior wall of pipe 24, nozzle 22 produces optimum cleaning and significantly reduces the "streaking" effect left by prior art nozzles. As depicted in FIG. 5, Nozzle 22 has at least two lower jets 100, 102 which point away from the head of the nozzle 22 and one upper jet 104, which points generally in the direction of the head 106 of the nozzle 22. FIG. 5 shows a first imaginary horizontal line 110, which is a central line which bisects nozzle 22.

Referring to FIG. 6, a plan view of nozzle 22 looking down at the head 106 of nozzle 22 is illustrated with the lower jets 100, 102 positioned 30 degrees to 67.5 degrees from a second imaginary horizontal line 108. In FIG. 5b(1), lower jets 100 and 102 are positioned 30 degrees from horizontal line 108. In FIG. 7(2), lower jets 100 and 102 are positioned 60 degrees from horizontal line 108. In FIG. 7(3), lower jets 100 and 102 are positioned 67.5 degrees from horizontal line 108. The positioning of jets 100, 102 in FIG. 6(1), (2) or (3), depends upon numerous variables including pipe diameter, surface conditions, length of pipe to be cleaned and type of deposits or coatings. Referring to FIG. 7, lower jets 100, 102 can be positioned 30 degrees to 60 degrees from horizontal line 110. In FIG. 7(1), jets 100, 102 have been positioned 60 degrees from horizontal line 110. In FIG. 7(2), jets 100, 102 have been positioned 30 degrees from horizontal line 110. The positioning of jets 100, 102 with respect to horizontal line 110, FIG. 7(1) and (2) depends upon the same considerations as earlier mentioned: pipe diameter, surface conditions, length of pipe to be cleaned and type of deposits or coatings. In FIG. 8, the upper jet 104 can be positioned 30 degrees to 60 degrees from horizontal line 110. In FIG. 8(1), upper jet 104 has been positioned 30 degrees from horizontal line 110. In FIG. 8(2), upper jet has been positioned 60 degrees from horizontal line 110.

The nozzle 22 may also have alternate embodiments as shown in FIG. 9, FIG. 10 and FIG. 11. FIG. 9, a biased nozzle 112 having a rounded top or dome 114, distinctive shoulders 116 and thicker walls. FIG. 10 is a flat-topped, bias nozzle 118, having a flat top 120, a beveled side 122, distinctive shoulders 124, jets 100, 102 are recessed and not flush with the circumference of nozzle 118, and nozzle 118 has notches 126 to hold retaining rings 128 and protective cover 130 (See FIG. 13). FIG. 11 is a biased nozzle 132 with a pointed head 106 and having a wide central notched band 136. FIG. 12 illustrates a nozzle 138, which is similar to the nozzle 112, with the exception that the fluid inlet chamber 140 is of a much larger diameter than the fluid inlet chamber 142 of nozzle 112 (See FIG. 9). FIG. 13 depicts a protective cover 130, which can be composed of a variety of polymers or metals. The protective cover 130 absorbs the shock and friction created when the nozzle 22 or any alternate embodiments 112, 118, 132, 138 encounter the interior surface of the pipe. The protective cover 130 is a band-like cover which protects nozzle 22 and alternate nozzle embodiments 112, 118, 132, 138.

Referring now to FIGS. 1, 2, 3, 22, 23 and 24 a flex lance drive 200 is illustrated. Said flex lance drive 200 may be substituted for rolling platform 16 which includes swivel joint 34 to rotate high pressure hose 20. Unlike rolling platform 16 and swivel joint 34, said flex lance drive 200 does not roll back and forth in a linear manner but remains generally stationary. Moreover, flex lance drive 200 includes a retractable spring-operated spool 202 which contains a finite amount of high pressure hose 204. Virtually, an unlimited amount of high pressure hose 20 may be inserted using rolling platform 16 and swivel joint 34, however the flex lance drive 200 can only include a finite amount of high pressure hose 204. The flex lance drive 200 also includes a spring 206 in combination with spool 202 which provides tension on the spool 202 for automatic rewinding of the high pressure hose 204 after completion of the pipe cleaning. The flex lance drive 200 is further comprised of a gyroscope yoke framework 208 which engages and rotates the spool 202. The gyroscope yoke framework 208 is suspended between front support bearings 210 and rear support bearings 211. The support bearings 210, 211 elevate the gyroscope yoke framework 208 and allow for lateral rotation of the gyroscope yoke framework 208, a first hollow shaft 220, a second hollow shaft 221, the spool 202, the finite length of high pressure hose 204, a first rotary coupling 212 and a high pressure hose 214. Support bearings 210, 211 are in turn supported and elevated by a plurality of vertical support members 216. A second rotary coupling 218 conveys high pressure fluid from high pressure hose 50 through the hollow shaft 221 and into high pressure hose 214. The hollow shafts 220, 221 and the gyroscope yoke framework 208, including the spool 202, high pressure hose 204, the first rotary coupling 212 and high pressure hose 214 are all rotated when a driven sprocket 222 is rotated by a drive sprocket 224 using a drive chain 226. Drive sprocket 224 is rotated by the portable hydraulic powered unit 12 applying energy to a power source 228. The flex lance drive 200 is supported on a lightweight platform 230 composed of sheet steel and steel support members designed to provide a portable medium for the flex lance drive 200. The lightweight platform 230 has handle members 231 to provide the operator a secure hand hold. The flex lance drive 200 has a plurality of castors 232 allowing freedom of movement. The flex lance drive 200 also includes a cover 234 held in place with a plurality of latches 236 which prevents contact between foreign objects and the flex lance drive 200. The cover 234 also includes an aperture 235 to allow the high pressure line 204 to engage with the rotary hose drive 18. Once high pressure hose 204 has exited the gyroscope yoke framework 208, the first hollow shaft 220 and front support bearings 210, it enters the rotary hose drive 18, where the torque of the rotary hose drive 18 thrusts the high pressure hose 204 and the biased cleaning nozzle 22, 112, 118, 132 and 138 into the pipe 24.
