Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cylindrical inner surface cleaning device.

[0002]

[Prior art and its problems]

 Conventionally, the cleaning work of the inner surface of the tubular body, for example, the inner surface of the pipe has generally relied on manpower. That is, using a tool in which a brush is set up at the tip of the rod-shaped member or a waste cloth is attached, this is inserted into a pipe and repeatedly pushed or pulled in the axial direction by human power. As a result, since the brush or waste having elastic force rubs the inner surface of the pipe, dry dirt or dirt containing moisture, oil or the like is removed. However, such a conventional cleaning tool for a cylindrical inner surface relies on manual labor, so that the cleaning efficiency is remarkably poor, and a large number of people are required to remove terrible dirt.

Further, as a conventional cylindrical inner surface cleaning device, there is one disclosed in Japanese Utility Model Laid-Open No. Sho 64-8092. This is formed by forming a spiral groove on the outer circumference, arranging the drive shaft to be driven to rotate in a cylindrical shape, and engaging a guide protruding on the inner circumference of the ring-shaped brush with the spiral groove of the drive shaft. The ring-shaped brush is moved by rotationally driving the drive shaft to clean the cylindrical inner surface in the axial direction. Further, another conventional cylindrical inner surface cleaning device is disclosed in Japanese Utility Model Laid-Open No. Sho 64-31394. This has a hydraulic motor to be inserted into the tubular shape and a brush that is driven to rotate by the hydraulic motor. While feeding the washing oil hose that supplies the washing oil to the hydraulic motor from the winding drum, Clean the inner surface axially.

However, such a conventional cylindrical inner surface cleaning device has a drawback that it is inferior in cleaning ability, although it contributes to labor saving in cleaning work. That is, in the tubular inner surface cleaning device disclosed in Japanese Utility Model Laid-Open No. Sho 64-8092, the ring-shaped brush moves in the axial direction when the axial resistance of the ring-shaped brush is large. It tends to rotate only without doing.

On the other hand, in the tubular inner surface cleaning device disclosed in Japanese Utility Model Laid-Open No. 64-31394, since the rotation axis of the brush is orthogonal to the central axis of the tubular inner surface, the peripheral speed of the brush is reduced. There is a problem that a slow part is generated and the cleaning degree is different in the circumferential direction of the cylindrical inner surface, and when the brush is rotated at a high speed to improve the cleaning ability, the rotational reaction force of the brush becomes large in the hydraulic motor. Since it works, it is necessary to separately provide a rotation stopping mechanism for the hydraulic motor.

In addition, all of the above-described conventional cylindrical inner surface cleaning devices have a structure in which the inner surface of the cylindrical member is cleaned by a rotating brush, so that the inner surface of the cylindrical member having irregularities can be satisfactorily cleaned. There is a problem that you cannot do it. That is, the brush does not come into contact with the portions located in the front and back of the brush in the rotation direction of the periphery of the uneven portion, and cleaning cannot be performed. Further, when the dirt on the inner surface of the cylinder contains moisture, oil, etc., there is a problem in that the inner surface of the cylinder cannot be cleaned well by the brush.

[0007]

[Means for Solving the Problems]

 The present invention has been made in view of the above-mentioned conventional technical problems, and its configuration is such that a vibrating body, a brush provided on the outer periphery of the vibrating body, and a vibrating body are vibrated. A cylindrical inner surface cleaning device provided with a vibration generating mechanism, wherein a hygroscopic cloth-like member is disposed adjacent to the central axis of the brush. Is.

[0008]

[Action]

 The vibrating body having the brush and the vibration generating mechanism are integrally inserted into the cylindrical inner surface which is the surface to be cleaned, and the vibration generating mechanism is driven. As a result, the vibrating body is vibrated, and the brush integrated with the vibrating body vibrates. From this state, if the brush is moved in the axial direction of the cylindrical inner surface by pushing or pulling or by self-propelled, the brush rubs the cylindrical inner surface to clean it.

That is, the brush having an appropriate elastic repulsion force receives the high vibration of the vibration generating mechanism and elastically collides with the inner surface of the cylindrical body, and the minute rubbing associated with this collision is performed in a high cycle. The inner surface is cleaned. Even if the brush outer diameter is slightly larger than the inner diameter of the cylindrical inner surface, the brush moves in a vibrating state when the frictional force between the brush and the cylindrical inner surface due to the elastic force of the brush is relatively small. In addition to the fact that it is possible to do it with a light force, it is enough for one person, and it is also possible to make it self-propelled.

As described above, since the cleaning of the inner cylindrical surface is performed by the vibrating brush, even when there is unevenness on the inner cylindrical surface, it is difficult to form an uncleanable portion around the uneven portion. , The entire inner surface of the cylinder is cleaned well.

In addition, since the cloth-like member having a hygroscopic property is disposed adjacent to the brush in the direction of the central axis, the cloth-like member effectively prevents the inner surface of the cylinder from being contaminated by moisture, oil and the like. Cleaned up.

The second rotating shaft 172 is rotatably supported inside and is immovable in the direction of the central axis, and is rotatably supported by a second outer cylinder 30b described later by a pair of slide bearings 50 and 51.

The second rotary shaft 172 has a distal end portion connected to the base end portion of the first rotary shaft 171 so as to be capable of transmitting a slight movement in the central axis direction and rotational movement, and the base end portion thereof will be described later. The tip end of the rotary shaft 32a is connected to the center shaft 32a so as to be slightly movable and capable of transmitting rotational movement. Specifically, the flat plate portion formed at the tip end portion of the second rotation shaft 172 is inserted into the rectangular recess 171a at the base end portion of the first rotation shaft 171 shown in FIG. 6 to slightly move in the central axis direction. It is connected so that it can transmit rotational movements. The base end portion of the second rotating shaft 172 and the tip end portion of the motor shaft 32a are also connected by a similar structure.

The vibration generating mechanism 13 attached to the intermediate portion of the first rotating shaft 171 is composed of an eccentric rotating pendulum 13a as shown in FIGS. 1 and 6, and drives the second rotating shaft 172 to rotate it. The rotation of the first rotating shaft 171 causes the vibrating body 11 to vibrate in the circumferential direction.

The electric motor 32, which is a rotary drive source connected to the second rotating shaft 172, is fixed in the first outer cylinder 30 a, and the motor shaft 32 a is a tip portion of the first outer cylinder 30 a by the rolling bearing 52. It is rotatably supported by. 53 is a spacer interposed between the electric motor 32 and the inner ring of the bearing 52. The first outer cylinder 30a and the second outer cylinder 30b are connected to each other by serration so that they cannot rotate relative to each other, and the outward flange of the first outer cylinder 30a and the base end of the second outer cylinder 30b are stopped. It is connected by screws 55. Reference numeral 56 is a dust-proof seal ring interposed between the first outer cylinder 30a and the second outer cylinder 30b.

The electric motor 32 is then connected to the power supply 60 by a cabtire cable 32b. The cabtire cable 32b has an appropriate degree of flexibility, supplies electricity from the power source 60 to the electric motor 32, and functions as a connecting tool. Therefore, the tubular inner surface cleaning device can be moved by giving a pushing motion or a pulling motion to the cabtire cable 32b which is the connecting tool.

Further, the second outer cylinder 30b and the base end portion of the vibrated body 11 are coupled so as to be relatively immovable and relatively rotatable in the central axis direction. That is, the slide bearing 57 is fixed to the inner peripheral surface of the base end portion of the vibrating body 11, and the vibrating body 11 is rotatably supported by the second outer cylinder 30b on the inner peripheral surface of the slide bearing 57 and is The base end portion of the annular member 59 having an inward flange portion is fixed to the base end portion of the second outer cylinder 30b, and the inward flange portion of the distal end portion is vibrated through the slide bearing 61. It is engaged with the front end surface of the projecting portion of the body 11 to suppress relative movement in the central axis direction.

Reference numeral 62 denotes a rubber ring member fixed to the outer periphery of the annular member 59, and has a function of integrating the annular member 59 divided into two in consideration of the assembly thereof. It should be noted that an appropriate brush material 22 may be attached to the exposed portion of the outer periphery of the annular member 59 or the second outer cylinder 30b to add a function of cleaning the cylindrical inner surface 5. Further, the short tubular portion 30c extending from the outer periphery of the second outer casing 30b is externally fitted to the outer periphery of the base end portion of the vibrated body 11 with the seal ring 63 interposed therebetween to prevent dust during this period.

Next, the auxiliary vibrating body 3 and the cloth member 7 connected to the vibrating body 11 will be described. The auxiliary vibrating body 3 is rotatable and immovable in the direction of the central axis through a pair of rolling bearings 6a and 6b on a supporting rod 4 which is fixed to the tip of the vibrating body 11 by protruding in the central axis direction. Supported by. A cloth-like member 7 having a hygroscopic property is arranged on the outer peripheral surface of the auxiliary vibration body 3 provided adjacent to the vibrated body 11. The support rod 4 is detachably mounted on the vibrating body 11 by means of a pin 23.

As shown in the enlarged view of FIG. 3, the cloth-like member 7 has a cylindrical member 71 fixed to the auxiliary vibrating body 3 by a plurality of screws 3 a, and a plurality of cloth-like members 7 arranged on the outer periphery of the cylindrical member 71. A rubber-made annular member 72 provided, a porous member 73 such as a sponge disposed between the annular members 72, and a bag-shaped cloth member 74 that covers the entire porous member 73. The member 73 and the cloth member 74 are hygroscopic. The porous member 73 has an annular shape, and its outer diameter is set to be slightly larger than the inner diameter of the cylindrical inner surface 5.

The tubular member 71 has a flange portion 71a and a short tubular portion 71b at one end and an inward flange portion 71c at the other end, which are integrally formed of metal. However, the plurality of porous members 73 and the annular member 72 are integrally formed, and one end of the porous member 73 and the annular member 72 are locked to the flange portion 71a, and the thickness is adjusted by the rubber spacer 75. The disk member 76 is fixed to the inward flange portion 71c with the screw 77 to support the front end surface of the spacer 75 with which the front annular member 72 is locked. The cloth member 74 covers the whole of the porous member 73, the annular member 72, the spacer 75 and the disc member 76 supported by the tubular member 71, and is provided with a rubber band 78 wound around the short tubular portion 71b. One end of the cloth member 74 is fastened and attached. The cloth member 74 is formed of cotton cloth, water-filled oil paper, or the like.

Next, the operation of the above embodiment will be described. The support rod 4 including the auxiliary vibrating body 3 and the cloth-like member 7 is attached to the vibrated body 11 by the pin 23. In this state, the brush 12 and the cloth-like member 7 are integrally inserted into the tubular inner surface 5 having a hollow shape as shown in FIG. 2, and the electric motor 32 is provided outside the tubular inner surface 5 by the power source 60. To rotate. As a result, the motor shaft 32a and the rotating shaft 17, that is, the second rotating shaft 172 and the first rotating shaft 171 rotate, and the eccentric rotating pendulum 13a rotates, so that the vibration generating mechanism 13 operates. The first rotary shaft 171 with the rotary pendulum 13a is rotatably supported in the vibrating body 11 by the pair of rolling bearings 47 and 48. Therefore, the vibrating body 11 and the brush are driven by the vibration generating mechanism 13. The holder 18 is vibrated and the brush 12 vibrates in the circumferential direction.

As a result, each brush member 22 rubs the cylindrical inner surface 5 while vibrating in the circumferential direction, and is cleaned. That is, each brush material 22 having an appropriate elastic repulsive force elastically collides with the cylindrical inner surface 5 and minute rubbing associated with this collision is performed in a high cycle to clean the cylindrical inner surface 5. Since the brush 12 is formed by spirally winding the brush material 22 around the outer periphery of the brush holder 18, the cylindrical inner surface cleaning device including the brush 12 is self-propelled to clean the cylindrical inner surface 5.

The winding direction of the spiral brush and the rotation direction of the motor shaft 32a are opposite to each other, for example, the brush 12 is right-handed and the motor shaft 32a is rotated counterclockwise so that the brush 12 vibrates in the circumferential direction. Is given, the brush 12 moves forward. The brush 12 can also be forcedly moved in the axial direction of the cylindrical inner surface 5 by giving a pushing or pulling motion to the connecting tool made of the cabtire cable 32b.

The cleaning function is excellently exerted by pushing or pulling the connecting member formed of the cabtire cable 32b to forcibly give the brush 12 a back-and-forth movement with a short stroke. The forced movement of the brush 12 in the vibrating state requires only that the outer diameters of the brush material 22 and the cloth-like member 7 be slightly larger than the inner diameter of the tubular inner surface 5, and the elastic force of each brush material 22 be increased. The frictional force between the inner surface 5 and the cylindrical inner surface 5 is relatively small, and it can be performed with a light force, and one person is sufficient. In addition, since the connecting tool including the cab tire cable 32b is provided with flexibility, it is possible to clean the tubular inner surface 5 which is curved to some extent.

As described above, the vibration of the brush 12 in the circumferential direction is combined, and the brush material 22 vibrating in a complicated manner cleans the cylindrical inner surface 5, so that the cylindrical inner surface 5 has irregularities, grooves, and the like. Even in the case where there is such a portion, an uncleanable portion is unlikely to be formed around the uneven portion and the like, and the entire inner surface 5 of the cylinder is cleaned well and uniformly. Of course, if the brush material 22 is impregnated with a neutral detergent or the like for cleaning, the cleaning effect is further improved.

Next, a cleaning operation using the auxiliary vibrating body 3 and the cloth member 7 will be described. Since the above cleaning work is performed in the state where the support rod 4 is connected to the vibrating body 11 by the pin 23, even when the cylindrical inner surface 5 contains moisture and oil, the porous member 73 and the cloth portion Due to the hygroscopicity of the material 74, a good cleaning effect can be obtained. Further, since the auxiliary vibrating body 3 is rotatably supported by the support rod 4 with a pair of rolling bearings 6a and 6b interposed therebetween, the brush member 22, the vibrating body 11, the support rod 4 and the like during the cleaning work. Even when the cloth rotates around the central axis, the cloth member 74 is not subjected to an unreasonable force in the circumferential direction, and the cloth member 74 is apt to be prevented from being biased, and a good cleaning effect is obtained. Secured. The soiled cloth member 74 is replaced with a new one by detaching the band 78.

The annular member 72 arranged between the porous members 73 prevents local and excessive deformation of the porous member 73 whose thickness is adjusted by the spacer 75, and prevents deterioration of the cleaning action. . By removing the disk member 76 with the screw 77, the porous member 73 or the annular member 72 can be replaced with a new one. Further, the porous member 73 is impregnated with rust preventive oil and the above cleaning operation is performed, whereby the rust preventive oil can be applied to the cylindrical inner surface 5.

In addition, during the cleaning operation by the brush 12 or the cloth-like member 7, the vibrating brush 12 may concurrently rotate, and the brush holder 18 and the vibrating body 11 may gently rotate around the central axis. In such a case, the vibrated body 11 rotates with respect to the second outer cylinder 30b while being supported by the inner peripheral surface of the slide bearing 57. At that time, the relative movement of the vibrating body 11 and the second outer cylinder 30b in the central axis direction is suppressed by the annular member 59 while being supported by the slide bearing 61.

As described above, since the vibrating body 11 is rotatable with respect to the second outer cylinder 30b, the second outer cylinder 30b, The linking tool including the first outer cylinder 30a and the cabtire cable 32b does not rotate, and twisting of the linking tool is prevented. Further, since the auxiliary vibrating body 3 and the cloth-like member 7 are rotatably supported by the support rod 4 as described above, they are not affected by the rotational movement of the brush 12.

Note that the brush material 22 of the brush 12 may be tilted in either the front or back direction from the direction orthogonal to the traveling direction, whereby the brush 12 that is vibrated may be configured to move by itself.

In the above embodiment, the eccentric rotary pendulum 13a is provided as the vibration generating mechanism 13 and is driven by the electric motor 32. However, various vibration generating mechanisms are adopted, and an air motor is also used. It can also be driven, and the vibration direction of the vibrated body 11 is not limited to the circumferential direction, and vibrations in all directions such as the axial direction, the radial direction, and the tangential direction can be applied to obtain a substantially similar cleaning action. However, in the case of the pneumatic vibration generating mechanism 13, the cabtire cable 32b, which is a connecting tool, is a double air hose that sends and discharges pressurized air, and the power source 60 is an air source.

Further, the cylindrical inner surface 5 is not limited to a circular cross section and may have a rectangular cross section. When the cylindrical inner surface 5 has a rectangular cross section, an outer shape suitable for each brush material 22 of the brush 12 is provided. It Further, in the above-mentioned embodiment, the vibrating body 11 is provided with the auxiliary vibrating body 3 and the cloth-like member 7, but the porous member 73 and the cloth member 74 are attached to a part of the outer peripheral surface of the vibrating body 11. Even if they are ring-attached, it is possible to obtain substantially the same operation as that of the above-mentioned embodiment regarding the work of cleaning dirt including moisture, oil and the like.

[0036]

[Effect of device]

 As can be understood from the above description, according to the present invention, it is possible to obtain a cylindrical inner surface cleaning device having a simple structure in which vibration is applied to the brush by the vibration generating mechanism, and the brush itself is rotated. It is possible to clean the cylindrical inner surface having irregularities, the cylindrical inner surface having a rectangular cross section, and the like, as well, compared with the case of cleaning by means of cleaning. Also, compared to cleaning by rotating the brush, the brush can be moved more reliably and easily in the axial direction of the inner surface of the cylinder, and the mechanism that supports the rotational reaction force is unnecessary and the structure is simple. Is.

Further, since the cloth-like member having a hygroscopic property is disposed adjacent to the brush in the direction of the central axis thereof, it is possible to satisfactorily clean dirt including moisture, oil and the like.
