- the tip end of the cutting blade projection is aligned with the edge of the metal cutting disc 24, and the cutting edge of the blade 32 is inclined radially inwardly and rearwardly toward the structure of the metal cutting disc 24.
- a propulsion unit 40 is located at the opposite end 18 of the shaft 14.
- the propulsion unit 40 includes a rigid axle 42 secured adjacent the second end 18 of the axle 14, a plurality of rigid sector segment panels 44 extending radially outward from the axle 42 and each segment panel 44 Independent hard extension aileron 46.

Segmentation The plates 44 are hinged independently so that they can be rotated about eight different axes along the outer edge of the axle 42 relative to the axle 42. The axis of rotation of the segmented panel 44 is tangent to the imaginary inscribed circle in the axle 42 relative to the axle 42 and is in contact with the eight outward straight edges at the point of tangency.
- the ailerons 46 are generally trapezoidal in shape and are hinged to the first edge 56 of the segmented panel 44 by a linear, radially-leafed sheet 62, each of which can be independently rotated, as best shown in FIG. This embodiment.
- a single extension aileron 46 is hinged to each of the segmented panels 44 along the first edge 56 and extends behind the next adjacent segmented panel 44, thus contacting and overlapping a portion of the upstream face.
- a rotating blocking plate 48 is fixed to the central shaft 14 immediately downstream of the propulsion unit 40.
- the rotating blocking plate 48 is a rigid steel rotating disk having a diameter of about 12 inches and having an opening 49 adapted to the central shaft 14 in the center.
- the rotating blocking plate 48 limits the rotation of the segmented panel 44 axially relative to the axle 42 toward the downstream end 16 of the central shaft 14.
- the rotation blocking plate 48 limits the segmented panel 44 from rotating toward the downstream end 16 toward the downstream end 16 of the central shaft 14, but allows the segmented panel 44 to move away from the downstream end 16 and the blocking plate 48, It is free to rotate toward the downstream end 18 of the central shaft 14.
- each expansion aileron 46 is pressed against the upstream face portion of the segmented panel 44, abutting each sectoral aileron 46 attached segment panel 44.
- the backing seal 50 is mounted upstream of the central shaft 14 adjacent to the propulsion unit 40.
- the backing seal is formed from a piece of rubber that is 0.5 inches thick and extends the same distance radially outwardly from the segmented panel 44.
- the rubber backing seal 50 is formed from the same rubber material typically used in the manufacture of conveyor belts.
- a rubber backing seal 50 is mounted on the central shaft 14 against the side of the axle 42 opposite the blocking plate 56 on the axle 42. That is, the axle 42 is located between the blocking plate 56 and the backing seal 50 on the shaft 14.
- the sealing disk 50 has a radial crack 52 therein that extends inwardly from the periphery of the backing seal 50 by a distance equal to the length of the edges 56 and 58 of the segmented panel 44.
- the crack 52 divides the outer peripheral portion of the backing seal 50 Into eight petals-like segments 55.
- the radial crack 52 defined by the sealing disk 50 is angularly aligned with the gap between the segmented panels 44.
- the pipe cleaning tool depicted in Figures 1-7 has a propulsion unit axle 42 that is octagonal in shape. There are therefore eight different segmented panels 44 in the propulsion unit 40.
- the backing seal 50 is thus arranged at a 45 degree interval extending inwardly from the periphery of the backing sealing disk 50 to eight radial cracks 52 about 3 inches from the central axial opening 53 in the backing sealing disk 50.
- the central opening 53 is large enough to allow passage of the extended central shaft 14.
- the crack 52 in the backing sealing disc 5 is thus aligned from the gap between the angle and the longitudinal direction and the advancement unit segment panel 44.
- the propulsion unit 40 has a unique ability to fold a large distance, so that a pressure difference is established between the upstream and downstream sides of the backing seal 50, the pressure difference is due to the difference in diameter accumulated on both sides of the rust and calcification deposits, and in the pipe 12
- the internal deposition accumulates in different diameters.
- the axle 42, the segmented panel 44, the extended aileron 46 and the backing seal 50 collectively extend radially outward from the central shaft 14 until reaching the inner wall of the conduit 12 or the clogging deposit 67 along the blocked conduit 12 requiring cleaning. Extending toward the inner surface.
- segmented panels 44 since there are a plurality of segmented panels 44, and each of the segmented panels 44 is independently hinged to the axle 42, the different segmented panels 44 are independent of the other segmented panels 44, each being folded or extended to The extent necessary to reach the surrounding duct wall or deposit layer 67. This allows the system to accommodate the unevenness of the plugging deposits 67 accumulated on the inner circumference of the pipe 12.
- the segmented panels 44 are movable between extended positions that are generally coplanar with the axle 42 and perpendicular to the central axis 42 to their folded back position in the upstream direction opposite the directional arrow 20 shown in Figure 2, relative to the center
- the shaft 14 is stopped at an angle of approximately 45 degrees.
- the extreme outer end edge of the segmented panel 44 and the extended aileron 46 may be from a maximum radial position of approximately 20 inches from the central shaft 14 when the segmented panel 44 is parked in a substantially coplanar relationship with the axle 42 to Folding occurs when the segmented panel is at an angle of about 40 degrees with respect to the axis 14 and at a 50 degree angle to the plane of the axle 42 to a distance of about 13.75 inches from the center of the shaft 14.
- the extension aileron 46 When the segment panel 44 is in a direction substantially coplanar with the axle 42 , the extension aileron 46 is remote from the edge 47 of the hinge connecting the aileron 46 to the segment panel 44 at the first segment panel edge 56, and The second edge 58 of the adjacent segment panel 44 overlaps less. Since the segmented panel 44 is folded inwardly toward the axis 14, adjacent segments The width of the gap between the panels 44 is reduced and the extended ailerons 46 are drawn across the upstream face of the segmented panels 44 there.
- the propulsion unit 40 formed by the axle 42, the segmented panel 44 and the extended aileron 46 can thus be folded, from a generally disc-shaped configuration to a structure shaped like a top cone.
- the composite structure of the axle 42, the segmented panel 44 and the extended aileron 46 is a strong, rigid, radially moveable plug in the central opening of the conduit 12. This clogging of the liquid flow is enhanced by the addition of a water impermeable backing seal 50 which significantly contributes to limiting fluid flow from the propulsion unit 40.
- the axle 42, segmented panel 44 and extension aileron 46 form a rigid structure that resists the force of fluid flow as the cleaning tool 10 moves along the conduit end 12, protecting the backing seal from damage. At the same time, the backing seal 50 limits the penetration of the propellant liquid through the propulsion unit 40. If there are no segmented panels 44 and extension ailerons 46, the periphery of the backing seal 50 can simply be folded due to the force exerted by the fluid on the upstream end of the conduit 12.
- the segmented panel 44 and the extended aileron 46 and the axle 42 together exhibit a rigid structure that resists fluid forces applied from the upstream end 12 of the conduit.
- the clogging formed by the advancement unit 40 and the backing seal 50 does not form a seal that is impermeable to liquid.
- a certain amount of fluid will flow through the periphery of the outer edge of the backing seal 50, the segmented panel 44, and the extended aileron 46.
- the unit of the propulsion unit 40 and the backing seal 50 is formed between the upstream end of the cleaning tool 10 adjacent the second upstream end 18 of the shaft 14 and the downstream end of the cleaning tool adjacent the first downstream end 16 of the shaft 14.
- the radially extending serrations 26 on the outer edge of the cutting disk 24 pass through the cumulative blockage of deposits 67 adhering to the inner wall of the pipe 12, thereby breaking up these deposits from the pipe wall. Remove them.
- the water that is not flowing through the propulsion unit 40 carries these broken deposits downstream.
- the efficiency of the cleaning action of the cleaning tool 10 is enhanced by the presence of a longitudinally extending blade 32 located around the downstream face 30 of the cutting disk 24.
- the position of the blade 32 around the outside of the cutting disk 24 causes the sheet and broken deposition material to be forced to move radially inward along the center of the pipe 12, where it can pass through the middle of the enclosed deposit 67.
- the blocked opening 68 carries the deposit downstream.
- the cutting disk 24 preferably has a plurality of openings 66 located at a short distance radially inward from its toothed periphery.
- the openings 66 are preferably about 1 inch in diameter and are located in pairs on either side of the four tear and crush blades 32.
- the opening 66 provides water that flows through the propulsion unit 40, wherein water can flow through the low resistance flow path. The flow of liquid through opening 66 is used to rinse and carry away the particulate material of deposit 67 after those materials have been torn and crushed by blade 32 and serrations 26.
- the extended support mechanism of the cleaning tool 10 includes an axle 42 and a 1.25 inch diameter threaded shaft 14 to which the cutting unit 22 is mounted, and a small diameter metal that is concentrically aligned with the shaft 14 and securely mounted.
- the fixed disks 72 each have a flat surface and an opposite face with an annular alignment groove 74.
- the alignment disk 72 has faces that are aligned with the grooves 74 to be placed opposite each other at the opposite ends of the reinforcing tube 70.
- the alignment disk 72 also has a central axial opening 76 that accommodates the presence of the central shaft 14.
- the pipe cleaning tool 10 is assembled with the extended threaded support shaft 14 inserted through a central axial opening 76 of an alignment disk 72 and through the central axis of the reinforcing tubular tube 70. Then another alignment plate 72 is mounted on the central shaft 14, and the circumferential end edge of the reinforcing tube 70 is mounted in the groove 74. The slot 74 maintains the enhanced circular tube 70 coaxially aligned with the shaft 14.
- the steel cutting disk 22 is thereafter mounted to the downstream end 16 of the shaft 14.
- An overweight internally threaded nut is advanced along the helix to the downstream end 16 of the shaft 14.
- a rotating blocking plate 48 is inserted over the shaft 14 such that the shaft 14 passes through a central axial bore of the rotating blocking plate 48.
- the rotating blocking plate 48 is pressed against the smooth upstream face of the upstream alignment disk 72.
- the segmented panel 44 to which the axle 42 of the extension aileron 14 is hinged is then mounted to the shaft 14.
- the shaft 14 passes through a central axial opening 43 in the axle 42.
- the axle 42 is mounted such that the extended tail 42 is located on the upstream side of the segmented panel 44.
- a flat spacer disk 80 is then mounted on the shaft 14.
- the thickness of the spacer disk 80 is equal to the thickness of the extension aileron 46, and the outer diameter does not exceed the circumference of the axle 42.
- the shaft 14 extends through a central axial opening 80 in the spacer disk 80.
- the disc-shaped backing seal 50 is then mounted adjacent the spacer disk 80 and extends through the shaft 14 through the central axial opening 53 of the disc-shaped backing seal 50.
- a disk-shaped reinforcing plate 82 having an outer circumferential diameter equal to the distance from the eight sides of the axle 42 to the axis of the shaft 14 is attached to the shaft 14.
- the second, upstream end of the shaft 14 extends through a central axial opening 83 of the stiffener 82.
- the two nuts 84 are then screwed to the second upstream end of the shaft 14 and tightened.
- the cutting disk 22 is held by the reinforcing tube 70 from the structure to the propulsion unit 40 at a fixed, predetermined distance.
- the nuts 34 and 84 at the opposite ends of the shaft 14 press the cutting unit 22 and the advancement unit 40 against the reinforcing tube 70 and clamp them at a fixed position of the shaft 14.
- the duct 12 has an interior cleaned by a duct cleaning tool 10 surrounded by a cylindrical annular wall 13 in which the deposit is blocked.
- the cleaning work is performed by forming an opening at both ends of the pipe 12 and providing an internal inlet there. These ends and their corresponding openings are generally shown in Figures 2 with 86 and 88. End 86 can be considered the upstream end and 88 is the downstream end.
- the opening of the pipe cleaning tool 10 at the upstream end is then inserted into the interior of the pipe end 12 such that the upstream surface of the segmented panel 44 faces the upstream end 86 of the pipe section into which the tool 10 is inserted.
- the water is then advanced under pressure by the upstream end 86 of the pipe section 12. Water flows in the direction indicated by directional arrow 20, exerting a force on the backing seal 50. This force is transmitted to the upstream face of the segmented panel 44 and also acts on the extended aileron 46.
- the hydraulic pressure tends to rotate the segmented panel 44 outwardly toward the annular wall surface 13 of the conduit 12.
- the hydraulic pressure also tends to press against the fan-shaped blades of the backing sealing disk 50 to the upstream faces of the segmented panels 44 and the extension ailerons 46, and also presses the expansion ailerons 46 into close contact with the upper surface of the segmented panels 44 to the expansion pair.
- the extent to which the wings 46 thus overlap these faces.
- the fluid force tends to restrict the flow of fluid through the propulsion unit 40, thereby creating a pressure differential across the opposite sides of the composite structure formed by the backing seal 50, the axle 42, the segmented panel 44, and the extended aileron 46.
- the pressure differential across the propulsion unit 40 drives the pipe cleaning tool 10 to move toward the downstream end of the pipe end 12.
- the serrations 26 of the cutting unit 22 are looped from the pipe section 12.
- the wall 13 removes the plugged deposits 67.
- the blade 32 which tears and crushes the deposited material 67, axially inward toward the unblocked central opening 68 of the pipe section 12, assisting in the removal of deposits 67.
- Water flowing through the propulsion unit 10 moves along the fluid passage opening 66 of the cutting disk 22, around the periphery of the cutting disk 22, carrying broken particulate matter from the deposit 67 to the downstream end 88 of the pipe section 12 in front of the pipe cleaning tool 10. .
- the pipe cleaning tool 10 floats the pipe section 12 at the downstream end 88. The pipe cleaning tool is then removed from the opening of the downstream end 88 of the pipe section 12.
- the pipe section 12 can be cleaned by the pipe cleaning tool 10 from there once. In some cases, it is in fact sufficient that the pipe cleaning tool 10 passes through the pipe section 12 once to remove all deposits 67. In other cases, the adhesion of the deposit 67 to the inner wall 13 of the pipe section 12 is particularly strong, requiring the pipe cleaning tool 10 to pass through the pipe section 12 multiple times.
- the progressively larger diameter cutting disc 22 In the case where the deposits 67 are relatively hard and firmly adhered to the inner duct wall 13, it may be necessary to use the progressively larger diameter cutting disc 22 as the tool 10 continues to pass through the duct section 12 to gradually increase the serrations 26 and support. The distance between the axes 14. In such a case, a cutting disk having a diameter that is only slightly larger than the unblocked opening 68 can be employed first. Once the cleaning unit 10 has passed through the pipe section 12, the first page is the smallest cutting disk removed from the shaft 14 and replaced with a larger diameter cutting disk. Several progressively larger diameter cutting discs can be used in sequence. However, the components of the propulsion unit 40 need not be exchanged because the propulsion unit 40 is folded radially inwardly to a diameter from an outer diameter of up to approximately 20 inches to a diameter as small as approximately 13.75 inches.
- the use of the propulsion unit 40 greatly reduces the time and expense and the water pressure required to clean the pipe section 12.
- the pipe cleaning tool 10 depicted in Figures 1-7 requires only about 120-135 psi (pounds per square inch) of water pressure to propel through a 20 inch diameter 3000 inch long pipe section.
- Figures 8 and 9 show an alternative embodiment of the invention.
- the first or upstream end 116 of the pipe cleaning tool 110 has a cutting unit 122 mounted therein while the second or downstream end 118 of the threaded shaft 14 supports the propulsion unit 140.

- Each of the sector cutting elements 124 has a narrower, radially inner end with a radially extending mounting opening 125 at the same location.
- Each mounting opening 102 is in the form of a long slot and is closed at both ends.
- the cutting unit 122 also includes a bolt 115 for each cutting element plate 124.
- Each bolt 115 has an outer threaded shank extending through the smooth, edged opening of the downstream cutting element mounting disk 108 and threadedly engages the internally threaded opening 111 in the cutting element mounting disk 106.
- the cutting element mounting plates 106 and 108, the elongated slots 125 and the bolts 115 form an adjustment mechanism that allows the radial distance of the serrations 126 to the shaft 114 to be selectable and adjustable.
- the bolts 115 are loosened allowing the flat sector cutting element plate 124 to adjust the radial distance extending from the shaft 114.
- the limit of adjustment is determined by the oblong groove 125.
- the pipe cleaning tool 10 has a reinforcing tube 170 that is coaxially mounted about the support shaft 114. Reinforced tube The 170 is coaxially aligned with respect to the shaft 114 by an annular groove corresponding to the downstream surface of the downstream cutting element mounting disk 198 and an annular groove corresponding to the upstream face of the steel alignment disk 172 at the opposite end of the tube 170.
- the overall length of the tube 170 is about 12 inches.
- Tube 170 can be a standard tube wall stainless steel tube having an inner diameter of 3 inches and a wall thickness of about 0.125 inches.
- the pipe cleaning tool 110 is used in substantially the same manner as the pipe cleaning tool 10. That is, a pipe section to be cleaned is opened at both ends, and the pipe cleaning tool 110 is inserted into the upstream end of the pipe section. The second or downstream end 118 of the pipe cleaning tool 110 is first inserted into the open end upstream of the pipe section and the tool 110 is pushed into the pipe section to be washed.

- the water pressure acts on the upstream surface of the soft, water-impermeable disc-shaped backing seal 150, so that the six sectors of the flattened seal 150 are on the upstream face of the segmented panel 144, and the cover section of the expanded aileron 146 portion Panel 144.
- the periphery of the segmented panel 144 and the extended aileron 146 are in contact with the inner wall surface of the duct or in contact with the inner surface of the material accumulated on the inner wall surface, forming a pressure differential across the propulsion unit 140. That is, the water pressure acting on the upstream surface of the backing seal 150 is higher than the water pressure flowing through the projections. As a result, the pressure differential established across the propulsion unit 140 pushes the pipe cleaning tool 110 longitudinally along the pipe until it emerges from the downstream end. As the serrations 126 are pulled through the accumulated material accumulated on the inner wall of the pipe, the material is broken and carried downstream, through the portion of the water flowing through the propulsion unit 140.
- the sector-shaped cutting plate 124 can be adjusted from the initial direction to project a relatively short distance radially outward from the shaft 114.
- the pipe cleaning tool 110 is advantageous because the radial extent of the serrations 126 to the support shaft 114 can be adjusted quickly and easily. This adjustment can be done for all cutting elements 124 in only about 10 minutes. Therefore, when the tool cleaning tool 110 continuously passes through the pipe section to be cleaned, it can be quickly deployed.

图1和图2显示了一个管道清洁工具10,它以适合的尺寸形成,在内径为20英寸的一段管道12里穿过管道段一次把管道12清洗干净。管道清洁工具10由一根延长的中央轴14组成,它是一根外螺纹直径为1.25英寸的B7钢螺柱。轴14的长度由管道12的弯曲直径限定。如果能够的话,中央轴14最好尽可能的长,来维持清洁工具10与管道12在长度上对齐。然而,管道清洁工具10必须足够短,它才能移动穿过管道12的弯曲。在无人船所使用的工业范围内,管道12的弯曲通常有一个标准直径,等于管道内径的1.5倍。因此,对于一根20
英寸的管道,中央轴14的最大长度的典型值为大约30英寸。Figures 1 and 2 show a pipe cleaning tool 10 which is formed in a suitable size to clean the pipe 12 once through the pipe section in a length of pipe 12 having an inner diameter of 20 inches. The pipe cleaning tool 10 consists of an elongated central shaft 14 which is a B7 steel stud with an external thread diameter of 1.25 inches. The length of the shaft 14 is defined by the curved diameter of the conduit 12. If desired, the central shaft 14 is preferably as long as possible to maintain the cleaning tool 10 aligned with the length of the conduit 12. However, the pipe cleaning tool 10 must be short enough to move through the bend of the pipe 12. In the industrial range used by unmanned vessels, the bend of the pipe 12 typically has a standard diameter equal to 1.5 times the inner diameter of the pipe. So for a 20
The maximum length of the central shaft 14 is typically about 30 inches for an inch pipe.
在图1和2说明的实施例中,中央轴14有第一端16,在这个实施例中是下游的一端,一个相对的第二端18,是上游末端。管道12里面推进管道清洁工具10的水的流动方向如图箭头20标识。In the embodiment illustrated in Figures 1 and 2, the central shaft 14 has a first end 16, in this embodiment a downstream end, and an opposite second end 18, which is an upstream end. The direction of flow of water propelling the pipe cleaning tool 10 inside the pipe 12 is indicated by arrow 20.
一个坚硬的切割单元22固定在轴14的第一端16附近。在图1-7描述的实施例中,采用了一个单个固定直径的切割元件22。切割单元22由一个全直径的钢切割板24组成,钢切割板24外径略小于20英寸,厚度约0.5英寸。坚硬且平坦的盘状金属板24的外围是锯齿状来形成径向向外伸出的锯齿26,如图3所示。金属切割板有一个上游面28和一个相对的下游面30。金属切割板24在它的下游面30通过一个拧在中央轴14的第一端16上的保持螺母34固定在位。A rigid cutting unit 22 is secured adjacent the first end 16 of the shaft 14. In the embodiment depicted in Figures 1-7, a single fixed diameter cutting element 22 is employed. The cutting unit 22 is comprised of a full diameter steel cutting plate 24 having an outer diameter of slightly less than 20 inches and a thickness of about 0.5 inches. The periphery of the hard and flat disc-shaped metal plate 24 is serrated to form serrations 26 projecting radially outward, as shown in FIG. The metal cutting board has an upstream face 28 and an opposite downstream face 30. The metal cutting plate 24 is held in place on its downstream face 30 by a retaining nut 34 that is threaded onto the first end 16 of the central shaft 14.
如图2和3所示,多个锋利的、三角形、纵向伸出的刀片状的突出32被以相等的间隔靠着切割板24的外围焊在金属切割板24的下游面30上而固定。切割刀片突起的尖端与金属切割盘24的边缘对齐,刀片32的切割边缘向内径向倾斜并向后朝着金属切割盘24的结构。As shown in Figures 2 and 3, a plurality of sharp, triangular, longitudinally projecting blade-like projections 32 are secured at equal intervals against the periphery of the cutting plate 24 to the downstream face 30 of the metal cutting plate 24. The tip end of the cutting blade projection is aligned with the edge of the metal cutting disc 24, and the cutting edge of the blade 32 is inclined radially inwardly and rearwardly toward the structure of the metal cutting disc 24.
一个推进单元40位于轴14的相对的一端18。推进单元40包括一个在轴14第二端18附近固定的坚硬的轮轴42,多个从轮轴42径向向外伸出的坚硬的扇形分段嵌板44,和每个分段嵌板44上的独立的坚硬扩展副翼46。一个旋转的阻挡板48和一个由不渗水的材料的软片形成的衬背密封盘50分别在推进单元40的下游和上游侧。A propulsion unit 40 is located at the opposite end 18 of the shaft 14. The propulsion unit 40 includes a rigid axle 42 secured adjacent the second end 18 of the axle 14, a plurality of rigid sector segment panels 44 extending radially outward from the axle 42 and each segment panel 44 Independent hard extension aileron 46. A rotating barrier plate 48 and a backing sealing disk 50 formed of a film of water impermeable material are on the downstream and upstream sides of the propulsion unit 40, respectively.
轮轴42有一个中央圆形的开口43,通过开口43轮轴42可以安装到中央轴14上。轮轴42的外周界是一个规则的多边形的形式。在图1-7说明的实施例中轮轴42是八边形的。轮轴42的周边八边中每个长约4英寸。分段嵌板44约0.5英寸厚,形状为圆的扇形去掉尖的松弛钢板。每个分段嵌板44有中凸的圆弧状外边缘52和较短的直线内边缘54。分段嵌板44也有径向向外分叉的第一边缘56和第二边缘58。The axle 42 has a central circular opening 43 through which the axle 42 can be mounted to the central shaft 14. The outer perimeter of the axle 42 is in the form of a regular polygon. The axle 42 is octagonal in the embodiment illustrated in Figures 1-7. Each of the eight sides of the periphery of the axle 42 is about 4 inches long. The segmented panel 44 is approximately 0.5 inches thick and is shaped as a circular sector to remove the sharp, relaxed steel sheet. Each segmented panel 44 has a convex arcuate outer edge 52 and a shorter straight inner edge 54. The segmented panel 44 also has a first edge 56 and a second edge 58 that are radially outwardly bifurcated.
分段嵌板44是独立的通过直线合页连接件60铰接到轮轴42上的。分段嵌
板44被独立铰接,因此可以相对于轮轴42,绕沿着轮轴42外边缘的八条不同的轴旋转。分段嵌板44的旋转轴相对于轮轴42与轮轴42内假想的内切圆相切,并在相切点与八条向外的直边都接触。The segmented panels 44 are independently hinged to the axle 42 by a linear hinge connector 60. Segmentation
The plates 44 are hinged independently so that they can be rotated about eight different axes along the outer edge of the axle 42 relative to the axle 42. The axis of rotation of the segmented panel 44 is tangent to the imaginary inscribed circle in the axle 42 relative to the axle 42 and is in contact with the eight outward straight edges at the point of tangency.
扩展副翼46一般是梯形状,通过直线的沿着径向的活页62,铰接到分段嵌板44的第一边缘56上,每个都可以独立的旋转,如图5最佳的表示出该实施例。单个扩展副翼46沿着第一边缘56铰接到每个分段嵌板44,并在下一个相邻分段嵌板44后面延伸,因此与上游面的一部分接触并重叠。The ailerons 46 are generally trapezoidal in shape and are hinged to the first edge 56 of the segmented panel 44 by a linear, radially-leafed sheet 62, each of which can be independently rotated, as best shown in FIG. This embodiment. A single extension aileron 46 is hinged to each of the segmented panels 44 along the first edge 56 and extends behind the next adjacent segmented panel 44, thus contacting and overlapping a portion of the upstream face.
旋转阻挡板48固定在中央轴14紧接着推进单元40的下游。旋转阻挡板48是一个直径约12英寸,中央有适应中央轴14的开孔49的坚硬的钢旋转盘。旋转阻挡板48限制分段嵌板44相对于轮轴42轴向上朝着中央轴14的下游末端16旋转。在图1-7的实施例中,旋转阻挡板48限制分段嵌板44向下游方向朝着中央轴14的下游末端16旋转,但允许分段嵌板44远离下游末端16和阻挡板48,朝着中央轴14下游末端18自由旋转。A rotating blocking plate 48 is fixed to the central shaft 14 immediately downstream of the propulsion unit 40. The rotating blocking plate 48 is a rigid steel rotating disk having a diameter of about 12 inches and having an opening 49 adapted to the central shaft 14 in the center. The rotating blocking plate 48 limits the rotation of the segmented panel 44 axially relative to the axle 42 toward the downstream end 16 of the central shaft 14. In the embodiment of FIGS. 1-7, the rotation blocking plate 48 limits the segmented panel 44 from rotating toward the downstream end 16 toward the downstream end 16 of the central shaft 14, but allows the segmented panel 44 to move away from the downstream end 16 and the blocking plate 48, It is free to rotate toward the downstream end 18 of the central shaft 14.
如图1所示,在分段嵌板44向前旋转,沿着下游方向达到旋转阻挡板48允许的最大可能程度时,相邻的分段嵌板44间存在大宽度的间隙。在下游方向的旋转限制下,分段嵌板44与轮轴42大体共面对齐,并且向外径向延伸。扩展副翼46足够宽,能跨越相邻的分段嵌板44间存在的空隙。当水从管道12的上游末端沿着方向箭头20表示的方向被推向下游时,每个扩展副翼46都被压在分段嵌板44的上游面部分,紧靠着每个扇形副翼46附属的分段嵌板44。As shown in FIG. 1, when the segmented panel 44 is rotated forward and reaches the maximum extent allowed by the rotational blocking plate 48 in the downstream direction, there is a large width gap between adjacent segmented panels 44. The segmented panel 44 is generally coplanarly aligned with the axle 42 and extends radially outwardly under rotational constraints in the downstream direction. The extended ailerons 46 are wide enough to span the gaps existing between adjacent segmented panels 44. When water is pushed downstream from the upstream end of the conduit 12 in the direction indicated by the directional arrow 20, each expansion aileron 46 is pressed against the upstream face portion of the segmented panel 44, abutting each sectoral aileron 46 attached segment panel 44.
衬背密封50被安装在中央轴14紧邻推进单元40的上游。衬背密封由一片0.5英寸厚,与分段嵌板44径向向外延伸相同距离的橡胶形成。橡胶衬背密封50由通常用于传送带制造的相同的橡胶材料形成。橡胶衬背密封50靠着轮轴42在轮轴42上与阻挡板56相对的一面安装在中央轴14上。也就是,轮轴42在轴14上位于阻挡板56和衬背密封50之间。The backing seal 50 is mounted upstream of the central shaft 14 adjacent to the propulsion unit 40. The backing seal is formed from a piece of rubber that is 0.5 inches thick and extends the same distance radially outwardly from the segmented panel 44. The rubber backing seal 50 is formed from the same rubber material typically used in the manufacture of conveyor belts. A rubber backing seal 50 is mounted on the central shaft 14 against the side of the axle 42 opposite the blocking plate 56 on the axle 42. That is, the axle 42 is located between the blocking plate 56 and the backing seal 50 on the shaft 14.
密封盘50内部有径向裂缝52,从衬背密封50的周边向里延伸与分段嵌板44的边缘56和58的长度相等的距离。裂缝52将衬背密封50的外周边部分分
成八个花瓣状的分段55。密封盘50定义的径向裂缝52与分段嵌板44间的空隙角度上对齐。The sealing disk 50 has a radial crack 52 therein that extends inwardly from the periphery of the backing seal 50 by a distance equal to the length of the edges 56 and 58 of the segmented panel 44. The crack 52 divides the outer peripheral portion of the backing seal 50
Into eight petals-like segments 55. The radial crack 52 defined by the sealing disk 50 is angularly aligned with the gap between the segmented panels 44.
图1-7中描述的管道清洁工具有周边为八边形的推进单元轮轴42。因此在推进单元40有八个不同的分段嵌板44。衬背密封50因此有间隔45度布置,从衬背密封盘50的周边向里延伸到距衬背密封盘50里的中央轴向开口53约3英寸处的八个径向裂缝52。中央开口53足够大允许延伸的中央轴14的通过。衬背密封盘5里的裂缝52因此从角度和纵向与推进单元分段嵌板44之间的空隙对齐。The pipe cleaning tool depicted in Figures 1-7 has a propulsion unit axle 42 that is octagonal in shape. There are therefore eight different segmented panels 44 in the propulsion unit 40. The backing seal 50 is thus arranged at a 45 degree interval extending inwardly from the periphery of the backing sealing disk 50 to eight radial cracks 52 about 3 inches from the central axial opening 53 in the backing sealing disk 50. The central opening 53 is large enough to allow passage of the extended central shaft 14. The crack 52 in the backing sealing disc 5 is thus aligned from the gap between the angle and the longitudinal direction and the advancement unit segment panel 44.
推进单元40有能折叠很大距离的独特能力,因此衬背密封50的上下游两侧建立起一个压力差,压力差是由于两侧水锈和钙化的沉积累积的直径不同,以及在管道12内沉积累积的直径不同。轮轴42、分段嵌板44、扩展副翼46和衬背密封50共同从中央轴14径向向外延伸直到到达管道12的内壁或者沿着需要清洗的堵塞的管道12的堵塞沉积物67径向的内表面延伸。The propulsion unit 40 has a unique ability to fold a large distance, so that a pressure difference is established between the upstream and downstream sides of the backing seal 50, the pressure difference is due to the difference in diameter accumulated on both sides of the rust and calcification deposits, and in the pipe 12 The internal deposition accumulates in different diameters. The axle 42, the segmented panel 44, the extended aileron 46 and the backing seal 50 collectively extend radially outward from the central shaft 14 until reaching the inner wall of the conduit 12 or the clogging deposit 67 along the blocked conduit 12 requiring cleaning. Extending toward the inner surface.
此外,由于有多个分段嵌板44,且每个分段嵌板44独立的铰接到轮轴42,不同的分段嵌板44独立于其它的分段嵌板44,每个折叠或延伸到必要的程度以到达包围的管道壁面或者沉积物层67。这允许系统适应在管道12内周面上累积的堵塞沉积物67的不均匀性。In addition, since there are a plurality of segmented panels 44, and each of the segmented panels 44 is independently hinged to the axle 42, the different segmented panels 44 are independent of the other segmented panels 44, each being folded or extended to The extent necessary to reach the surrounding duct wall or deposit layer 67. This allows the system to accommodate the unevenness of the plugging deposits 67 accumulated on the inner circumference of the pipe 12.
分段嵌板44能够在与轮轴42大体共面和垂直于中央轴42的延伸位置间移动到它们与图2中所示方向箭头20相反的上游方向上的折叠回去的位置,在相对于中央轴14大约45度角处停止。分段嵌板44的极外端边缘和扩展副翼46可以,从当分段嵌板44停在基本与轮轴42成共面关系时距中央轴14近20英寸的最大的径向位置,到当分段嵌板相对于轴14成约40度角和与轮轴42在的平面成50度角时到轴14的中心约13.75英寸的距离,进行折叠。The segmented panels 44 are movable between extended positions that are generally coplanar with the axle 42 and perpendicular to the central axis 42 to their folded back position in the upstream direction opposite the directional arrow 20 shown in Figure 2, relative to the center The shaft 14 is stopped at an angle of approximately 45 degrees. The extreme outer end edge of the segmented panel 44 and the extended aileron 46 may be from a maximum radial position of approximately 20 inches from the central shaft 14 when the segmented panel 44 is parked in a substantially coplanar relationship with the axle 42 to Folding occurs when the segmented panel is at an angle of about 40 degrees with respect to the axis 14 and at a 50 degree angle to the plane of the axle 42 to a distance of about 13.75 inches from the center of the shaft 14.
当分段嵌板44在与轮轴42基本共面的方向时,扩展副翼46远离在第一分段嵌板边缘56处连接副翼46到分段嵌板44的合页的边缘47,与相邻分段嵌板44的第二边缘58重叠较少。由于分段嵌板44被向内向轴14折叠,相邻的分段
嵌板44间间隙的宽度减小,扩展副翼46划过紧邻那里的分段嵌板44上游面。由轮轴42、分段嵌板44和扩展副翼46形成的推进单元40可以因此被折叠,从一个大体为盘状的构型,到形状类似去顶锥体的结构。尽管如此,通过它的折叠运动,轮轴42、分段嵌板44和扩展副翼46的复合结构为对管道12中央开口里的牢固的、坚硬的径向可以移动的塞。这种对液体流动的阻塞,通过增加不渗水的衬背密封50加强,它显著有助于限制从推进单元40的流体流动。When the segment panel 44 is in a direction substantially coplanar with the axle 42 , the extension aileron 46 is remote from the edge 47 of the hinge connecting the aileron 46 to the segment panel 44 at the first segment panel edge 56, and The second edge 58 of the adjacent segment panel 44 overlaps less. Since the segmented panel 44 is folded inwardly toward the axis 14, adjacent segments
The width of the gap between the panels 44 is reduced and the extended ailerons 46 are drawn across the upstream face of the segmented panels 44 there. The propulsion unit 40 formed by the axle 42, the segmented panel 44 and the extended aileron 46 can thus be folded, from a generally disc-shaped configuration to a structure shaped like a top cone. Nonetheless, by its folding movement, the composite structure of the axle 42, the segmented panel 44 and the extended aileron 46 is a strong, rigid, radially moveable plug in the central opening of the conduit 12. This clogging of the liquid flow is enhanced by the addition of a water impermeable backing seal 50 which significantly contributes to limiting fluid flow from the propulsion unit 40.
轮轴42、分段嵌板44和扩展副翼46形成一个坚硬的结构,在清洁工具10沿着管道端12移动时,阻止流体流动的力,保护衬背密封不被损坏。同时,衬背密封50限制了推进液体穿过推进单元40的渗透。如果没有分段嵌板44和扩展副翼46,会由于流体施加在管道12上游末端的力而简单地折叠衬背密封50的外围。分段嵌板44和扩展副翼46及轮轴42共同呈现出一个坚硬的结构,抵抗从管道上游末端12施加来的流体力。The axle 42, segmented panel 44 and extension aileron 46 form a rigid structure that resists the force of fluid flow as the cleaning tool 10 moves along the conduit end 12, protecting the backing seal from damage. At the same time, the backing seal 50 limits the penetration of the propellant liquid through the propulsion unit 40. If there are no segmented panels 44 and extension ailerons 46, the periphery of the backing seal 50 can simply be folded due to the force exerted by the fluid on the upstream end of the conduit 12. The segmented panel 44 and the extended aileron 46 and the axle 42 together exhibit a rigid structure that resists fluid forces applied from the upstream end 12 of the conduit.
当然推进单元40和衬背密封50形成的堵塞不会形成一个连液体都不能透过的密封。有一定量的流体会穿过衬背密封50外边的外围、分段嵌板44和扩展副翼46流动。裂缝52,和扩展副翼46和它被压倒的分段嵌板44的上游面间也会有一些流体的泄漏。不管怎样,推进单元40与衬背密封50共同构成的单元形成了临近轴14的第二上游末端18的清洗工具10上游末端和靠近轴14的第一下游末端16的清洗工具的下游末端之间显著的压力差。Of course, the clogging formed by the advancement unit 40 and the backing seal 50 does not form a seal that is impermeable to liquid. A certain amount of fluid will flow through the periphery of the outer edge of the backing seal 50, the segmented panel 44, and the extended aileron 46. There is also some leakage of fluid between the crack 52, and the upstream surface of the expansion aileron 46 and the segmented panel 44 on which it is overstruck. Regardless, the unit of the propulsion unit 40 and the backing seal 50 is formed between the upstream end of the cleaning tool 10 adjacent the second upstream end 18 of the shaft 14 and the downstream end of the cleaning tool adjacent the first downstream end 16 of the shaft 14. Significant pressure difference.
只要液体压力差足够大来维持工具10的运行,一定量流体通过坚硬的切割单元22是必须的。由于从管道12的上游末端施加水的液压,沿着指向箭头20表示的方向,到推进单元40,管道12内建立起的压力差推动着管道清洁工具10沿着管道12从上游末端纵向向待清洗管道端的下一端移动。It is necessary that a certain amount of fluid passes through the rigid cutting unit 22 as long as the liquid pressure difference is large enough to maintain the operation of the tool 10. Due to the hydraulic pressure exerting water from the upstream end of the conduit 12, in the direction indicated by the arrow 20, to the propulsion unit 40, the pressure differential established within the conduit 12 urges the conduit cleaning tool 10 to longitudinally along the conduit 12 from the upstream end. The lower end of the cleaning pipe end moves.
随着管道清洗工具10的移动,在切割盘24外侧边缘上的径向延伸的锯齿26穿过粘附在管道12内壁上的沉积物67的累积堵塞,从而破碎这些沉积物并从管道壁上去除它们。非流动通过推进单元40的水携带这些破碎的沉积物向下游。
As the pipe cleaning tool 10 moves, the radially extending serrations 26 on the outer edge of the cutting disk 24 pass through the cumulative blockage of deposits 67 adhering to the inner wall of the pipe 12, thereby breaking up these deposits from the pipe wall. Remove them. The water that is not flowing through the propulsion unit 40 carries these broken deposits downstream.
清洁工具10清洁行动的效率由于位于切割盘24下游面30周围的纵向延伸的刀片32的出现而得以增强。刀片32在切割盘24的外侧周围的位置,引起成片的和破碎的沉积材料被强行沿着管道12的中心径向向内运动动,在那里它可以穿过包围的沉积物67中间的未被堵塞的开口68将沉积物携带到下游。The efficiency of the cleaning action of the cleaning tool 10 is enhanced by the presence of a longitudinally extending blade 32 located around the downstream face 30 of the cutting disk 24. The position of the blade 32 around the outside of the cutting disk 24 causes the sheet and broken deposition material to be forced to move radially inward along the center of the pipe 12, where it can pass through the middle of the enclosed deposit 67. The blocked opening 68 carries the deposit downstream.
如图3所示,切割盘24优选的带有多个位于从它齿状外围径向向里短距离处的多个开口66。在图1-7说明的本发明的实施例中,在盘状的金属板24靠近每个刀片32处有两个开口66在两侧。开口66优选直径约1英寸,成对的位于四个撕裂和压碎刀片32的两边。开口66提供流过推进单元40的水,其中水可以流动穿过低阻力流道。穿过开口66的液体流动,在那些材料被被刀片32和锯齿26撕裂和压碎后用来冲洗并带走沉积物67的颗粒材料。As shown in Figure 3, the cutting disk 24 preferably has a plurality of openings 66 located at a short distance radially inward from its toothed periphery. In the embodiment of the invention illustrated in Figures 1-7, there are two openings 66 on either side of the disc-shaped metal plate 24 adjacent each blade 32. The openings 66 are preferably about 1 inch in diameter and are located in pairs on either side of the four tear and crush blades 32. The opening 66 provides water that flows through the propulsion unit 40, wherein water can flow through the low resistance flow path. The flow of liquid through opening 66 is used to rinse and carry away the particulate material of deposit 67 after those materials have been torn and crushed by blade 32 and serrations 26.
为了增强管道清洁工具10的刚度,清洁工具10的延长支撑机构包括轮轴42和切割单元22安装到的1.25英寸直径的螺纹轴14,以及一个与轴14同心共轴对齐牢固安装的小口径的金属圆柱状增强管70。管70通过一对硬橡胶对齐盘72固定在位。固定盘72每个有一个平面和一个有环形对齐槽74的相对面。对齐盘72带有对齐槽74的面以相互面对的关系放置在增强管70相对的尾端。对齐盘72也有中央轴向开口76,适应中央轴14的存在。To enhance the stiffness of the pipe cleaning tool 10, the extended support mechanism of the cleaning tool 10 includes an axle 42 and a 1.25 inch diameter threaded shaft 14 to which the cutting unit 22 is mounted, and a small diameter metal that is concentrically aligned with the shaft 14 and securely mounted. A cylindrical reinforcing tube 70. Tube 70 is held in place by a pair of hard rubber alignment discs 72. The fixed disks 72 each have a flat surface and an opposite face with an annular alignment groove 74. The alignment disk 72 has faces that are aligned with the grooves 74 to be placed opposite each other at the opposite ends of the reinforcing tube 70. The alignment disk 72 also has a central axial opening 76 that accommodates the presence of the central shaft 14.
组装管道清洁工具10,延伸的螺纹支撑轴14插入,穿过一个对齐盘72的中央轴向开口76,再穿过增强圆管70的中央轴。然后另一个对齐盘72安装在中央轴14上,增强圆管70的圆周状末端边缘安装在槽74里。槽74保持增强圆管70与轴14共轴对齐。其后钢切割盘22安装到轴14的下游末端16。一个超重的内螺纹螺母被沿螺旋推进到轴14的下游末端16。The pipe cleaning tool 10 is assembled with the extended threaded support shaft 14 inserted through a central axial opening 76 of an alignment disk 72 and through the central axis of the reinforcing tubular tube 70. Then another alignment plate 72 is mounted on the central shaft 14, and the circumferential end edge of the reinforcing tube 70 is mounted in the groove 74. The slot 74 maintains the enhanced circular tube 70 coaxially aligned with the shaft 14. The steel cutting disk 22 is thereafter mounted to the downstream end 16 of the shaft 14. An overweight internally threaded nut is advanced along the helix to the downstream end 16 of the shaft 14.
在相对的轴14的上游末端18,旋转阻挡板48插到轴14上,使轴14穿过旋转阻挡板48的中心轴向孔。旋转阻挡板48压在上游对齐盘72的光滑的上游面。然后具有扩展副翼14的轮轴42被铰接到的分段嵌板44并安装到轴14上。轴14穿过轮轴42里的中央轴向开口43。轮轴42的安装要让扩展尾翼42位于分段嵌板44的上游侧。
At the upstream end 18 of the opposing shaft 14, a rotating blocking plate 48 is inserted over the shaft 14 such that the shaft 14 passes through a central axial bore of the rotating blocking plate 48. The rotating blocking plate 48 is pressed against the smooth upstream face of the upstream alignment disk 72. The segmented panel 44 to which the axle 42 of the extension aileron 14 is hinged is then mounted to the shaft 14. The shaft 14 passes through a central axial opening 43 in the axle 42. The axle 42 is mounted such that the extended tail 42 is located on the upstream side of the segmented panel 44.
接着一个平的间隔盘80安装在轴14上。间隔盘80的厚度与扩展副翼46的厚度相等,外径不超过轮轴42的周界。轴14延伸穿过间隔盘80里的中央轴向开口80。然后盘状衬背密封50与间隔盘80相邻安装,通过轴14延伸穿过盘状衬背密封50的中央轴向开口53。然后,一个盘状增强板82,其外圆周直径与轮轴42的八条边到轴14的轴线的距离相等,安装到轴14上。轴14的第二即上游末端延伸穿过加强盘82的中央轴向开口83。然后两个螺母84被拧到轴14的第二上游末端并被拧紧。A flat spacer disk 80 is then mounted on the shaft 14. The thickness of the spacer disk 80 is equal to the thickness of the extension aileron 46, and the outer diameter does not exceed the circumference of the axle 42. The shaft 14 extends through a central axial opening 80 in the spacer disk 80. The disc-shaped backing seal 50 is then mounted adjacent the spacer disk 80 and extends through the shaft 14 through the central axial opening 53 of the disc-shaped backing seal 50. Then, a disk-shaped reinforcing plate 82 having an outer circumferential diameter equal to the distance from the eight sides of the axle 42 to the axis of the shaft 14 is attached to the shaft 14. The second, upstream end of the shaft 14 extends through a central axial opening 83 of the stiffener 82. The two nuts 84 are then screwed to the second upstream end of the shaft 14 and tightened.
当切割工具10装配时,切割盘22通过增强管70从结构里面与推进单元40保持一个固定、预先决定的距离。轴14相对的末端的螺母34和84把切割单元22和推进单元40压向增强管70并在轴14的固定位置夹紧它们。When the cutting tool 10 is assembled, the cutting disk 22 is held by the reinforcing tube 70 from the structure to the propulsion unit 40 at a fixed, predetermined distance. The nuts 34 and 84 at the opposite ends of the shaft 14 press the cutting unit 22 and the advancement unit 40 against the reinforcing tube 70 and clamp them at a fixed position of the shaft 14.
管道12,具有由堵塞沉积物存在的圆柱状环状壁面13包围的采用管道清洁工具10清洁的内部。清洁工作通过在管道12的两端形成开口并在那里提供内部的入口被执行。这些末端和它们对应的开口在图2里一般用86和88显示。末端86可以认为是上游末端而88是下游末端。The duct 12 has an interior cleaned by a duct cleaning tool 10 surrounded by a cylindrical annular wall 13 in which the deposit is blocked. The cleaning work is performed by forming an opening at both ends of the pipe 12 and providing an internal inlet there. These ends and their corresponding openings are generally shown in Figures 2 with 86 and 88. End 86 can be considered the upstream end and 88 is the downstream end.
然后管道清洁工具10在上游末端的开口被插到管道端12的内部,从而分段嵌板44的上游表面面对着工具10被插入的管道段的上游末端86。然后水在压力的作用下被推进管道段12上游末端86。水以方向箭头20表示的方向流动,在衬背密封50上施加作用力。这个力传到分段嵌板44的上游面,也作用在扩展副翼46上。液压力趋向于将分段嵌板44向外朝着管道12的环状壁面13旋转。液压力也趋向压着衬背密封盘50的扇形叶片到分段嵌板44和扩展副翼46的上游面上,也压着扩展副翼46与分段嵌板44的上表面紧密接触到扩展副翼46从而使这些面重叠的程度。因此,流体力趋向于限制流体穿过推进单元40的流动,从而在衬背密封50、轮轴42、分段嵌板44和扩展副翼46的复合结构形成的阻碍相对的两侧形成压力差。The opening of the pipe cleaning tool 10 at the upstream end is then inserted into the interior of the pipe end 12 such that the upstream surface of the segmented panel 44 faces the upstream end 86 of the pipe section into which the tool 10 is inserted. The water is then advanced under pressure by the upstream end 86 of the pipe section 12. Water flows in the direction indicated by directional arrow 20, exerting a force on the backing seal 50. This force is transmitted to the upstream face of the segmented panel 44 and also acts on the extended aileron 46. The hydraulic pressure tends to rotate the segmented panel 44 outwardly toward the annular wall surface 13 of the conduit 12. The hydraulic pressure also tends to press against the fan-shaped blades of the backing sealing disk 50 to the upstream faces of the segmented panels 44 and the extension ailerons 46, and also presses the expansion ailerons 46 into close contact with the upper surface of the segmented panels 44 to the expansion pair. The extent to which the wings 46 thus overlap these faces. Thus, the fluid force tends to restrict the flow of fluid through the propulsion unit 40, thereby creating a pressure differential across the opposite sides of the composite structure formed by the backing seal 50, the axle 42, the segmented panel 44, and the extended aileron 46.
穿过推进单元40的压力差驱使管道清洁工具10向管道端12的下游末端移动。随着清洁工具10向下游移动,切割单元22的锯齿26从管道段12的环状
壁面13移走堵塞沉积物67。撕裂和压碎沉积材料67的刀片32轴向向里朝着管道段12未堵塞的中央开口68,辅助沉积物67的去除。流动穿过推进单元10的水沿着切割盘22的流体通道开口66移动,绕着切割盘22的外围,在管道清洁工具10前面携带破碎的颗粒物质从沉积67到管道段12的下游末端88。最后,管道清洁工具10在下游末端88那里浮出管道段12。于是管道清洁工具从管道段12的下游末端88的开口移走。The pressure differential across the propulsion unit 40 drives the pipe cleaning tool 10 to move toward the downstream end of the pipe end 12. As the cleaning tool 10 moves downstream, the serrations 26 of the cutting unit 22 are looped from the pipe section 12.
The wall 13 removes the plugged deposits 67. The blade 32, which tears and crushes the deposited material 67, axially inward toward the unblocked central opening 68 of the pipe section 12, assisting in the removal of deposits 67. Water flowing through the propulsion unit 10 moves along the fluid passage opening 66 of the cutting disk 22, around the periphery of the cutting disk 22, carrying broken particulate matter from the deposit 67 to the downstream end 88 of the pipe section 12 in front of the pipe cleaning tool 10. . Finally, the pipe cleaning tool 10 floats the pipe section 12 at the downstream end 88. The pipe cleaning tool is then removed from the opening of the downstream end 88 of the pipe section 12.
依赖于提供到切割盘22的抵抗力,管道段12可以被管道清洁工具10从那里穿过一次而清洗。有些情况下,事实上管道清洁工具10穿过管道段12一次就足够去除所有的沉积物67。在其他情况下,沉积物67到管道段12的内壁13的粘附特别强,需要管道清洁工具10多次穿过管道段12。Depending on the resistance provided to the cutting disk 22, the pipe section 12 can be cleaned by the pipe cleaning tool 10 from there once. In some cases, it is in fact sufficient that the pipe cleaning tool 10 passes through the pipe section 12 once to remove all deposits 67. In other cases, the adhesion of the deposit 67 to the inner wall 13 of the pipe section 12 is particularly strong, requiring the pipe cleaning tool 10 to pass through the pipe section 12 multiple times.
在那些沉积物67相当坚硬并且牢固的粘附在内管道壁13的情形下,可能需要工具10连续的穿过管道段12时采用逐渐增大直径的切割盘22,来逐渐增加锯齿26与支撑轴14间的距离。在这样的情形下,可以首先采用一个直径只比未堵塞开口68稍大的切割盘。一旦清洗单元10已经穿过管道段12,第一页是最小的切割盘从轴14移走换上一个直径较大的切割盘。可以顺序采用几个逐渐增大直径的切割盘。但是,推进单元40的零件不需要被交换,因为推进单元40径向向里折叠到从最大近20英寸的外边直径到小至约13.75英寸的直径。In the case where the deposits 67 are relatively hard and firmly adhered to the inner duct wall 13, it may be necessary to use the progressively larger diameter cutting disc 22 as the tool 10 continues to pass through the duct section 12 to gradually increase the serrations 26 and support. The distance between the axes 14. In such a case, a cutting disk having a diameter that is only slightly larger than the unblocked opening 68 can be employed first. Once the cleaning unit 10 has passed through the pipe section 12, the first page is the smallest cutting disk removed from the shaft 14 and replaced with a larger diameter cutting disk. Several progressively larger diameter cutting discs can be used in sequence. However, the components of the propulsion unit 40 need not be exchanged because the propulsion unit 40 is folded radially inwardly to a diameter from an outer diameter of up to approximately 20 inches to a diameter as small as approximately 13.75 inches.
采用推进单元40极大的减少了时间和费用以及清洁管道段12所需的水压。例如,图1-7中描述的管道清洁工具10,仅需要约120-135psi(磅每平方英寸)的水压来推进穿过一个20英寸直径3000英寸长的管道段。The use of the propulsion unit 40 greatly reduces the time and expense and the water pressure required to clean the pipe section 12. For example, the pipe cleaning tool 10 depicted in Figures 1-7 requires only about 120-135 psi (pounds per square inch) of water pressure to propel through a 20 inch diameter 3000 inch long pipe section.
图8和9显示了本发明的一个可选实施例。如图8所示,管道清洁工具110的第一或者上游末端116,有一个切割单元122安装在那里,同时,螺纹轴14的第二或下游末端118支撑着推进单元140。管道清洁工具110的切割单元122有绕它外围径向向外延伸的锯齿126,但也有一个改变锯齿126从延长支撑轴114向外延伸距离的可调节的切割片安装支撑,如图9所示。Figures 8 and 9 show an alternative embodiment of the invention. As shown in FIG. 8, the first or upstream end 116 of the pipe cleaning tool 110 has a cutting unit 122 mounted therein while the second or downstream end 118 of the threaded shaft 14 supports the propulsion unit 140. The cutting unit 122 of the pipe cleaning tool 110 has serrations 126 extending radially outwardly about its periphery, but there is also an adjustable blade mounting support that changes the distance the serrations 126 extend outwardly from the elongate support shaft 114, as shown in FIG. .
图8所示的管道清洁工具110的实施例可以建设来清洁与图2中所示管道
12相同或不同大小的管道。通过示例的方法,管道清洁工具10可以设计用于清洁内径为14英寸的管道。在这样的实施例中,螺纹轴114可以是直径为1.125英寸,长度为管道直径1.5倍的B7螺栓。也就是,轴114的长度大约是21英寸。The embodiment of the pipe cleaning tool 110 shown in Figure 8 can be constructed to clean the pipe shown in Figure 2.
12 pipes of the same or different sizes. By way of example, the pipe cleaning tool 10 can be designed to clean pipes having an inner diameter of 14 inches. In such an embodiment, the threaded shaft 114 can be a B7 bolt having a diameter of 1.125 inches and a length of 1.5 times the diameter of the pipe. That is, the length of the shaft 114 is approximately 21 inches.
管道清洁工具110的推进单元140以与图1-7中实施例的推进单元40相同的方法操作,推进单元140的零件和关联的元件也与推进单元40的零件和管理元件有相同的结构配置。也就是说,推进单元140有轮轴142,有短的直线边缘铰接到轮轴142上的分段嵌板144和扩展副翼146。阻挡板148位于轮轴142的下游,带有径向裂缝的衬背密封150位于轮轴142的上游。显示在图8的推进单元140的零件与图1-7显示的清洁工具10有关的描述的对应的推进单元的零件有相同的功能并且相互之间以同样的方式作用。The propulsion unit 140 of the duct cleaning tool 110 operates in the same manner as the propulsion unit 40 of the embodiment of Figures 1-7, and the components and associated components of the propulsion unit 140 also have the same structural configuration as the components and management elements of the propulsion unit 40. . That is, the propulsion unit 140 has an axle 142 with a short straight edge hinged to the segmented panel 144 and the extended aileron 146 on the axle 142. The blocking plate 148 is located downstream of the axle 142 and a backing seal 150 with radial cracks is located upstream of the axle 142. The parts of the propulsion unit 140 shown in Fig. 8 have the same function as the parts of the corresponding propulsion unit described in connection with the cleaning tool 10 shown in Figs. 1-7 and function in the same manner.
图8和9描述的实施例相关的零件的尺寸被按比例缩小用于一个较小直径的管道。对较小直径的管道,提供比图1-7实施例中数目少的分段嵌板144的推进单元经济上有利。更具体的,轮轴142是六边形的,因而推进单元140包括六个独立通过直线活页160绕轮轴142外围铰接的扇形嵌板144。从而每个扇形嵌板144相对轮轴142绕一个与轮轴42的每个外外边缘的边的中心点的假想内结圆相切的旋转轴旋转。The dimensions of the parts associated with the embodiments depicted in Figures 8 and 9 are scaled down for a smaller diameter pipe. For smaller diameter pipes, it is economically advantageous to provide a propulsion unit that has fewer number of segmented panels 144 than in the embodiment of Figures 1-7. More specifically, the axle 142 is hexagonal such that the propulsion unit 140 includes six sector panels 144 that are independently hinged about the periphery of the axle 142 by a linear flyer 160. Thus, each of the sector panels 144 is rotated relative to the axle 142 about a rotational axis that is tangential to the imaginary inner circle of the center point of the edge of each outer and outer edge of the axle 42.
推进单元140也包括六个不同的扩展副翼146,每个铰接到一个独立的分段嵌板44的第一边缘。盘形衬背密封150有六个径向裂缝,其结构从它的周界径向向里延伸终止于距轴114约3英寸的地方。The propulsion unit 140 also includes six different extension ailerons 146, each hinged to a first edge of a separate segment panel 44. The disc-shaped backing seal 150 has six radial slits whose structure extends radially inwardly from its perimeter and terminates approximately three inches from the shaft 114.
推进单元140和推进单元40之间的主要差别,除了不同的分段嵌板的数目和较小的外径,是推进单元140位于轴114的第二即下游末端。因此,推进单元140拉着清洁工具110穿过一个管道,与图1-7的实施例中中清洁工具10推着穿过管道12的推进单元40相对。The main difference between the propulsion unit 140 and the propulsion unit 40, except for the number of different segmented panels and the smaller outer diameter, is that the propulsion unit 140 is located at the second, downstream end of the shaft 114. Thus, the propulsion unit 140 pulls the cleaning tool 110 through a conduit opposite the propulsion unit 40 in which the cleaning tool 10 is pushed through the conduit 12 in the embodiment of Figures 1-7.
推进单元140安装在轴114的第二末端的下游末端向上游一定距离处。这种驱进单元140向后或上游的定位容纳了一个基本为球形的突起102。突起102有中心向外凸起的基本半球形的表面对着下游,并且由金属形成,在穿过图1
所示的被管道上累积的沉积物67堵塞的管道时,扩大中央开口。一个超大螺母134保持突起102固定在位,向后沿着上游的方向压着一个突起基础盘104。突起基础盘104依次支撑在旋转限制盘148上。The propulsion unit 140 is mounted at a downstream distance from the downstream end of the second end of the shaft 114. This rearward or upstream positioning of the drive unit 140 accommodates a substantially spherical projection 102. The protrusion 102 has a substantially hemispherical surface that is convex outwardly from the center, facing the downstream, and is formed of metal, as shown in FIG.
When the pipe shown by the deposit 67 accumulated on the pipe is shown, the central opening is enlarged. An oversized nut 134 holds the projection 102 in place and presses a raised base disc 104 rearwardly in the upstream direction. The protruding base discs 104 are sequentially supported on the rotation restricting disc 148.
管道清洁工具10的切割单元122与管道清洁单元10中采用的切割单元22显著不同。更具体的,切割单元122由一对切割元件安装盘106和108组成,在上游末端116那里相对于支撑轴114共轴的安装。每个切割元件安装盘106和108有等间隔隔开的多个开口111在它的外围。在图8-9的实施例中每个切割元件安装盘106和108上有六个安装元件开口111。安装开口111是径向的并且相互间纵向对齐。每个切割元件安装盘106和108还有中央轴向开口113适于支持轴114从其中穿过。The cutting unit 122 of the pipe cleaning tool 10 is significantly different from the cutting unit 22 employed in the pipe cleaning unit 10. More specifically, the cutting unit 122 is comprised of a pair of cutting element mounting discs 106 and 108 that are coaxially mounted relative to the support shaft 114 at the upstream end 116. Each of the cutting element mounting disks 106 and 108 has a plurality of openings 111 equally spaced apart at its periphery. In the embodiment of Figures 8-9 there are six mounting element openings 111 on each of the cutting element mounting discs 106 and 108. The mounting openings 111 are radial and longitudinally aligned with one another. Each cutting element mounting disk 106 and 108 also has a central axial opening 113 adapted to support the shaft 114 therethrough.
切割单元122由多个平的切割元件124组成,它们位于安装盘106和108之间并从那里径向向外延伸。每个切割元件124的形式是,外侧周带锯齿126的平坦扇形坚硬钢板。每个扇形切割元件124有一个较窄的,径向靠里的末端,并在同一处有径向延伸的安装开口125。每个安装开口102是长槽形式且两端闭合。The cutting unit 122 is comprised of a plurality of flat cutting elements 124 that are located between the mounting plates 106 and 108 and extend radially outward therefrom. Each cutting element 124 is in the form of a flat sector hard steel plate with outer peripheral band saw teeth 126. Each of the sector cutting elements 124 has a narrower, radially inner end with a radially extending mounting opening 125 at the same location. Each mounting opening 102 is in the form of a long slot and is closed at both ends.
切割单元122还包括用于每个切割元件板124的螺栓115。每个螺栓115有一个延伸穿过下游切割元件安装盘108上光滑的有边缘开口的外螺纹柄部,并且与切割元件安装盘106上的内螺纹开口111螺纹配合。切割元件安装盘106和108,长槽125和螺栓115形成了一个调节机制,允许锯齿126到轴114的径向距离可选且可调节。The cutting unit 122 also includes a bolt 115 for each cutting element plate 124. Each bolt 115 has an outer threaded shank extending through the smooth, edged opening of the downstream cutting element mounting disk 108 and threadedly engages the internally threaded opening 111 in the cutting element mounting disk 106. The cutting element mounting plates 106 and 108, the elongated slots 125 and the bolts 115 form an adjustment mechanism that allows the radial distance of the serrations 126 to the shaft 114 to be selectable and adjustable.
为调节锯齿126从轴114延伸出的距离,螺栓115被松开允许平坦扇形切割元件板124调节从轴114延伸的径向距离。调节的极限由长椭圆形槽125决定。一旦锯齿126从轴114延伸的径向距离被选定,再次拧紧螺栓115从而牢固地夹着扇形的切割元件板124,使其从切割元件安装盘106和108之间径向向外延伸,如图8和9所示。To adjust the distance the serrations 126 extend from the shaft 114, the bolts 115 are loosened allowing the flat sector cutting element plate 124 to adjust the radial distance extending from the shaft 114. The limit of adjustment is determined by the oblong groove 125. Once the radial distance over which the serrations 126 extend from the shaft 114 are selected, the bolts 115 are tightened again to securely sandwich the sector-shaped cutting element plates 124 from radially outwardly between the cutting element mounting discs 106 and 108, such as Figures 8 and 9 are shown.
管道清洁工具10里具有一个绕支撑轴114共轴安装的加强管170。增强管
170相对轴114保持共轴对齐,通过一个划入下游切割元件安装盘198下游表面的环状槽和一个在管170相对末端的钢对齐盘172的上游面对应的环状槽。管170的总长度,作为示例,约为12英寸。管170可以是一个标准管壁不锈钢管道,其内径为3英寸,壁厚约0.125英寸。The pipe cleaning tool 10 has a reinforcing tube 170 that is coaxially mounted about the support shaft 114. Reinforced tube
The 170 is coaxially aligned with respect to the shaft 114 by an annular groove corresponding to the downstream surface of the downstream cutting element mounting disk 198 and an annular groove corresponding to the upstream face of the steel alignment disk 172 at the opposite end of the tube 170. The overall length of the tube 170, by way of example, is about 12 inches. Tube 170 can be a standard tube wall stainless steel tube having an inner diameter of 3 inches and a wall thickness of about 0.125 inches.
管道清洁工具110以基本上与管道清洁工具10相同的方法使用。也就是,一个待清洗的管道段在两端开口,管道清洁工具110被插入管道段的上游末端。管道清洁工具110的第二或者下游的末端118首先被插入管道段上游的开口末端然后工具110被推入待洗的管道段。然后压力在100-135psi之间的水被迫使进入管道上游末端,并如方向箭头120表示的从管道段上游末端向下游末端的方向动作。The pipe cleaning tool 110 is used in substantially the same manner as the pipe cleaning tool 10. That is, a pipe section to be cleaned is opened at both ends, and the pipe cleaning tool 110 is inserted into the upstream end of the pipe section. The second or downstream end 118 of the pipe cleaning tool 110 is first inserted into the open end upstream of the pipe section and the tool 110 is pushed into the pipe section to be washed. Water having a pressure between 100 and 135 psi is then forced into the upstream end of the conduit and acts in the direction from the upstream end to the downstream end of the conduit as indicated by directional arrow 120.
水穿过切割单元122的扇形切割元件124之间,但作用在推进单元140形成的障碍物,以前面描述过的方式建立与背套密封150的压力差。如分段嵌板44,如果通过或者与待清洁的管道段的内壁的接触,或者与在那个壁上沉积物的接触被强迫向后,分段嵌板144能够绕活页160向里折叠,从旋转限制阻挡板148所限制的大致与轮轴142共面的方向,向后朝着轴114在上游的方向。Water passes between the sector-shaped cutting elements 124 of the cutting unit 122, but acts on the obstacle formed by the propulsion unit 140 to establish a pressure differential with the backing seal 150 in the manner previously described. As with the segmented panel 44, the segmented panel 144 can be folded inwardly around the leaflet 160 if it passes through or is in contact with the inner wall of the pipe section to be cleaned or is in contact with the deposit on that wall. The rotation restricting blocking plate 148 is restricted to a direction substantially coplanar with the axle 142, and is oriented rearward toward the upstream direction of the shaft 114.
尽管以箭头120的方向指向施加流体压力,推进单元140的分段嵌板144折叠向里朝着轴144,与管道内壁上累积的沉积物的接触相对应。该水压作用在柔软不渗水盘状的衬背密封150的上游表面上,因此展平密封150的六个扇形在分段嵌板144的上游面上,并且扩展副翼146部分的覆盖分段嵌板144。Although directed at the applied fluid pressure in the direction of arrow 120, the segmented panel 144 of the advancement unit 140 folds inwardly toward the shaft 144, corresponding to the contact of deposits accumulated on the inner wall of the conduit. The water pressure acts on the upstream surface of the soft, water-impermeable disc-shaped backing seal 150, so that the six sectors of the flattened seal 150 are on the upstream face of the segmented panel 144, and the cover section of the expanded aileron 146 portion Panel 144.
由于衬背密封150,分段嵌板144和扩展副翼146的外围与管道的内壁面接触,或者与内壁面上累积的材料的内表面接触,跨越推进单元140形成了一个压力差。也就是,作用在衬背密封150的上游面上的水压,比流过突起的水压高。作为结果,跨越推进单元140建立起来的压力差推动管道清洁工具110纵向的沿着管道前进直到它从下游末端出现。当锯齿126被拉着穿过管道内壁上累积的堆积材料,材料被破碎并携带到下游,通过流过推进单元140的那部分水。
Due to the backing seal 150, the periphery of the segmented panel 144 and the extended aileron 146 are in contact with the inner wall surface of the duct or in contact with the inner surface of the material accumulated on the inner wall surface, forming a pressure differential across the propulsion unit 140. That is, the water pressure acting on the upstream surface of the backing seal 150 is higher than the water pressure flowing through the projections. As a result, the pressure differential established across the propulsion unit 140 pushes the pipe cleaning tool 110 longitudinally along the pipe until it emerges from the downstream end. As the serrations 126 are pulled through the accumulated material accumulated on the inner wall of the pipe, the material is broken and carried downstream, through the portion of the water flowing through the propulsion unit 140.
如果累积在管道壁上的材料不是太厚,或者如果它可以不应用额外的液压力就能从管道壁面上取出,很有可能用管道清洁工具140穿过待清洗的管道段一次就清洁好一段管道。如果积累的材料更厚或者材料更牢固的粘结到管壁上,可能有必要清理出去材料。也就是,扇形的切割板124可以从最初就调节从轴114径向向外伸出一个相对短的距离。If the material accumulated on the pipe wall is not too thick, or if it can be removed from the pipe wall without applying additional hydraulic pressure, it is possible to clean the pipe section with the pipe cleaning tool 140 once. pipeline. If the accumulated material is thicker or the material is more firmly bonded to the pipe wall, it may be necessary to clean the material out. That is, the sector-shaped cutting plate 124 can be adjusted from the initial direction to project a relatively short distance radially outward from the shaft 114.
由于每个管道清洁工具110连续的穿过待清洗管道段,螺栓115被松开,在再次拧紧前,切割元件板124从切割元件安装盘106和108的中间开口113径向向外拉出一个递增的距离。这样,随着每次管道清洁工具110穿过管道段,一个直径逐步变大的孔穿过累积在管道壁上的材料,直到最后锯齿126几乎径向延伸到管壁并且几乎所有的材料被去除。Since each of the pipe cleaning tools 110 continuously passes through the pipe section to be cleaned, the bolts 115 are loosened, and before being tightened again, the cutting element plates 124 are pulled radially outward from the intermediate opening 113 of the cutting element mounting disks 106 and 108. Incremental distance. Thus, as each pipe cleaning tool 110 passes through the pipe section, a progressively larger diameter hole passes through the material accumulated on the pipe wall until the last serration 126 extends almost radially to the pipe wall and almost all of the material is removed. .
由于能够快速简单的调整锯齿126到支撑轴114的径向延伸程度,管道清洁工具110是有好处的。这个调节可以在仅大约10分钟的时间里对所有切割元件124完成。因此,工具清洁工具110连续穿过待清洗的管道段时,可以被快速的部署。The pipe cleaning tool 110 is advantageous because the radial extent of the serrations 126 to the support shaft 114 can be adjusted quickly and easily. This adjustment can be done for all cutting elements 124 in only about 10 minutes. Therefore, when the tool cleaning tool 110 continuously passes through the pipe section to be cleaned, it can be quickly deployed.
毫无疑问,很多本发明的变化和修改对于熟悉管道清洁工具的技术人员将变得显而易见的。例如,可以使用大量的调整装置来替代长形槽125和夹紧螺栓115以及显示的安装盘106和108,可以使用一个可调节的凸轮机构来迫使锯齿126从轴114径向向外移动到所需程度,同样的,不同的加固系统可以用来替换增强管70和170,以实例来说,间隔杆可以相互间以选定的角度间隔径向的绕中央支撑轴布置。相应的,本发明的范围不应当理解为受限于图解和描述的特定的实施例。It goes without saying that many variations and modifications of the present invention will become apparent to those skilled in the art of pipe cleaning tools. For example, a large number of adjustment devices can be used in place of the elongated slot 125 and the clamping bolt 115 and the mounted mounting plates 106 and 108, and an adjustable cam mechanism can be used to force the serrations 126 to move radially outward from the shaft 114 to the desired position. To the extent required, similarly, different reinforcement systems can be used to replace the reinforcement tubes 70 and 170, by way of example, the spacer rods can be arranged radially about each other at a selected angular interval about the central support shaft. The scope of the invention should not be construed as being limited to the particular embodiments illustrated and described.
虽然本发明已经参考特定的说明性实施例进行了描述,但是不会受到这些实施例的限定而仅仅受到附加权利要求的限定。本领域技术人员应当理解可以在不偏离本发明的保护范围和精神的情况下对本发明的实施例能够进行改动和修改。
