DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cylindrical inner surface cleaning device.

[0002]

2. Description of the Related Art Heretofore, cleaning of a cylindrical inner surface, for example, a pipe inner surface, has generally depended on manual labor. That is, a tool in which a brush is erected at the tip of the rod-shaped member is used, inserted into the pipe, and repeatedly pushed or pulled in the axial direction by human power. Thus, the brush having elasticity rubs the inner surface of the pipe, so that dirt is removed. However, such a conventional cleaning tool for the inner surface of a tube relies on human labor, so that the cleaning efficiency is extremely poor, and a large number of people are required for the operation of removing severe dirt.

[0003] As a conventional cylindrical inner surface cleaning device, there is one disclosed in Japanese Utility Model Laid-Open No. 64-8092. This is a configuration in which a spiral groove is formed on the outer periphery, a drive shaft that is rotationally driven is arranged in a cylinder, and a guide protruding from the inner periphery of the ring-shaped brush is engaged with the spiral groove of the drive shaft. Then, the ring-shaped brush is moved by rotating the drive shaft to clean the cylindrical inner surface in the axial direction. Further, as another conventional cylindrical inner surface cleaning device, there is one disclosed in Japanese Utility Model Laid-Open Publication No. 64-31394. This has a hydraulic motor inserted into the cylinder, and a brush rotated by the hydraulic motor. Clean the inner surface in the axial direction.

[0004] However, such a conventional cylindrical inner surface cleaning device has a drawback that although it contributes to labor saving of the cleaning operation, it has poor cleaning ability. That is,
In the cylindrical inner surface cleaning device disclosed in Japanese Utility Model Laid-Open Publication No. 64-8092, when the resistance of the ring-shaped brush to movement in the axial direction is large, the ring-shaped brush rotates without moving in the axial direction. Only tend to do.

On the other hand, in the cylindrical inner surface cleaning device disclosed in Japanese Utility Model Laid-Open Publication No. 64-31394, the rotation axis of the brush is orthogonal to the center axis of the cylindrical inner surface, so that the brush has a peripheral speed. There is a problem that a slow portion is generated, and the degree of cleaning is different in the circumferential direction of the cylindrical inner surface, and when a high rotation is applied to the brush to improve the cleaning ability, the rotational reaction force of the brush greatly acts on the hydraulic motor. Therefore, it becomes necessary to separately provide a rotation stopping mechanism for the hydraulic motor.

In addition, since the conventional cylindrical inner surface cleaning device has a structure in which the cylindrical inner surface is cleaned with a rotating brush, the cylindrical inner surface having irregularities is favorably cleaned. There is a defect that can not be. That is,
The brush does not come into contact with a portion located around the uneven portion before and after in the rotation direction of the brush, so that the brush cannot be cleaned.

[0008]

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 to drive the vibration generating mechanism. The vibration generating mechanism is driven by transmitting a driving force from a rotary driving source via a rotating shaft. Thus, the vibrated body is vibrated, and the brush integrated with the vibrated body vibrates. The vibration generating mechanism engages the annular groove and the protrusion that are inclined from a direction perpendicular to the center axis of the vibrated body, and generates vibration in the center axis direction on the vibrated body by the relative rotation of the annular groove and the protrusion. Because of this, the brush integrated with the vibrated body vibrates in the central axis direction.

In this state, if the brush is moved in the axial direction of the cylindrical inner surface by applying a push or pull to the rotating shaft or by self-running, the brush rubs and cleans the cylindrical inner surface while vibrating. That is, a brush having an appropriate elastic repulsion force,
Under the high vibration of the vibration generating mechanism, the cylinder collides elastically with the cylindrical inner surface, and the minute rubbing caused by the collision is performed in a high cycle to clean the cylindrical inner surface. The movement of the brush in the vibrating state is only the outer diameter of the brush is slightly larger than the inner diameter of the cylindrical inner surface,
The frictional force between the cylindrical inner surface based on the elasticity of the brush is relatively small, so it can be performed with a light force. is there.

As described above, since the cleaning of the cylindrical inner surface is performed by the vibrating brush, even if the cylindrical inner surface has irregularities, it is difficult to form an uncleanable portion around the irregularities. The entire surface of the cylindrical inner surface is cleaned well.

[0011] In addition, according to the second aspect of the present invention, similarly to the above description, the rotary shaft is rotationally driven by the rotary drive source to give relative rotation to the annular groove and the projection. The first brush attached to the first vibrating body is configured to apply vibration in the center axis direction to the first vibrating body.
Vibrates in the direction of the central axis. At this time, the first vibrating body is guided by the second vibrating body fitted movably in the center axis direction. In addition, when the rotating shaft is rotationally driven by the rotating drive source, the second vibration generating mechanism attached to the rotating shaft is driven to vibrate the second vibrating body. The attached second brush vibrates. The direction of vibration by the second vibration generating mechanism gives an arbitrary direction such as a circumferential direction and a radial direction.

Further, according to the invention described in claim 3,
When the rotary shaft is driven to rotate by a rotary drive source, this driving force is supplied to the vibration generating mechanism via the rotary shaft, and gives vibration to the vibrated body and the brush. At this time, even if relative rotation occurs between the outer cylinder and the vibrated body that rotatably insert the rotary shaft, since the bearing is interposed between the outer cylinder and the relative rotation, the outer cylinder is fitted to the outer cylinder. Twisting is prevented.

[0013]

It is connected to the part so as to be movable in the central axis direction and to be capable of transmitting rotational movement. Specifically, as shown in FIGS. 4 and 5, the flat plate portion 15c formed at the base end of the shaft member 15 is replaced with a rectangular recess 171 at the distal end of the first rotary shaft 171 as shown in FIG.
a so as to be able to transmit a slight movement and a rotational movement in the direction of the central axis. The first rotating shaft 1
The base end of the first rotary shaft 71 and the front end of the second rotary shaft 172 are connected by the same structure.

The second shaft attached to the intermediate portion of the first rotating shaft 171
As shown in FIGS. 1 and 9, the vibration generating mechanism 13 is constituted by an eccentric rotary pendulum 13 a, and the second vibration receiving mechanism is driven by the rotation of the second rotary shaft 172 to rotate the first rotary shaft 171. Vibration is given to the body 11 in the circumferential direction.

The second rotating shaft 172 is connected to a motor shaft 32a of an electric motor 32, which is a rotary driving source. The electric motor 32 is fixed in the first outer cylinder 30a, and the motor shaft 32a is rotatably supported at the tip of the first outer cylinder 30a by a rolling bearing 52. Reference numeral 53 denotes a spacer interposed between the electric motor 32 and the inner race of the partial bearing 52. Such a first outer cylinder 30a and a second outer cylinder 30

That is, the slide bearing 57 is fixed to the inner peripheral surface of the base end portion of the second vibrating body 11, is rotatably supported by the second outer cylinder 30 b on the inner peripheral surface of the slide bearing 57, and has inner ends at both ends. The base end portion of the annular member 59 having the facing flange portion is fixed to the base end portion of the second outer cylinder 30b, and the inward flange portion at the tip end portion of the second vibrating body 11 is interposed with the sliding bearing 61.

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 in consideration of its assembly. A function of cleaning the cylindrical inner surface 5 may be added by attaching an appropriate brush material 22 to the outer periphery of the annular member 59. Further, a short cylindrical portion 30c extending from the outer periphery of the second outer cylinder 30b
Is externally fitted to the outer periphery of the base end portion of the second vibrated body 11 with the seal ring 63 interposed therebetween, so that dust is prevented during this.

Next, the operation of the above embodiment will be described.
As shown in FIG. 2, the first brush 2 and the second brush 12 are integrally inserted into the hollow cylindrical inner surface 5, and the electric motor 32 is rotated by a power source 60 arranged outside the cylindrical inner surface 5. Drive. Accordingly, 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.
The vibration generating mechanism 13 operates. The first rotating shaft 171 with the rotating pendulum 13a is provided with a pair of rolling bearings 47 and 48.
Since the second is rotatably supported in the driven member 11, the second driven members 11 and the brush holder 18 is vibrated by the operation of the second vibration generating mechanism 13, the second driven members
11 and the second brush 12 vibrate in the circumferential direction.

As a result, each brush member 22 rubs against the cylindrical inner surface 5 while vibrating in the circumferential direction and is cleaned. That is,
Each of the brush members 22 having an appropriate elastic repulsion force elastically collides against the cylindrical inner surface 5 under the high vibration of the second vibration generating mechanism 13 , and the minute rubbing accompanying this collision is performed in a high cycle. The cylindrical inner surface 5 is cleaned. Since the brush member 22 is spirally wound around the outer periphery of the brush holder 18 of the second brush 12, the cylindrical inner surface cleaning device including the first brush 2 and the second brush 12 is self-propelled and the cylindrical inner surface 5 is cleaned. Cleaning work is performed.

In particular, according to the second brush 12, each of the brush members 22 vibrates in the circumferential direction, and self-propelled in this state, so that the corners in the circumferential direction of the uneven portions existing on the cylindrical inner surface 5 are good. To be cleaned. The winding direction of the helical brush and the rotation direction of the motor shaft 32a are opposite to each other.
2 is clockwise, the left rotation is given to the motor shaft 32a, and the circumferential vibration is given to the second brush 12, the second brush 1
2 moves forward. The first brush 2 and the second brush 12 can also be forcibly moved in the axial direction of the cylindrical inner surface 5 by giving a pushing or pulling force to the connecting member formed of the cabtire cable 32b.

On the other hand, the rotational driving force of the electric motor 32 is also transmitted from the rotating shaft 17 to the shaft member 15 attached to the first vibration generating mechanism 3, and the large diameter portion 15b having the annular groove 8 rotates. Since the annular groove 8 is engaged with the projection 7 formed on the second vibrated body 11, the shaft member 15 is vibrated in the central axis direction while rotating. The first vibrating member 1 includes a shaft member 1
5 is connected via the rolling bearing 40 and the inward flange-like member 1b, and slidably fits into the small-diameter portion at the distal end of the second vibrating member 11, so that it vibrates in the central axis direction.

Thus, each brush material 2 of the first brush 2
2 rubs the cylindrical inner surface 5 while vibrating in the direction of the center axis, and cleans the second brush 12 with a different vibration direction. In particular, according to the first brush 2, each brush material 22 vibrates back and forth, and runs in this state, whereby the front and rear corners of the uneven portion existing on the cylindrical inner surface 5 are favorably cleaned.

If the connecting member constituted by the cabtire cable 32b is pushed or pulled to force the first brush 2 and the second brush 12 to move back and forth in a short stroke, the cleaning function is improved. Be demonstrated. The forcible movement of the first and second brushes 2 and 12 in the vibrating state is performed only when the outer diameter of the brush material 22 is slightly larger than the inner diameter of the cylindrical inner surface 5. In addition to the fact that the frictional force with the cylindrical inner surface 5 based on the force is relatively small, the operation can be performed with a light force, and one person is sufficient. In addition, since the connecting member consisting of the cabtire cable 32b is given flexibility, the cylindrical inner surface 5 which is slightly curved is provided.
Cleaning is also possible.

As described above, the vibration of the second brush 12 in the circumferential direction and the vibration of the first brush 2 in the central axis direction are combined, and the brush member 22 that vibrates in a complicated manner cleans the cylindrical inner surface 5. Therefore, even when the cylindrical inner surface 5 has an uneven portion, a groove, or the like, an uncleanable portion hardly occurs around the uneven portion, and the entire surface of the cylindrical inner surface 5 is cleaned well and uniformly. . Of course, if the brush member 22 is impregnated with a neutral detergent or the like for cleaning, the cleaning effect is further improved.

In addition, during the cleaning operation by the first brush 2 and the second brush 12, a second vibration that particularly vibrates in the circumferential direction is performed.
In some cases, the brush 12 simultaneously rotates and the brush holder 18 and the second vibrating member 11 rotate slowly around the central axis. In such a case, the second vibrating 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 this time, the relative movement of the second vibrating body 11 and the second outer cylinder 30b in the center axis direction is suppressed by the annular member 59 while being supported by the slide bearing 61.

As described above, since the second vibrating member 11 is rotatable with respect to the second outer cylinder 30b, the second vibrating member 11 is rotated with the second outer cylinder 30b.
Even when the brush 12 makes a rotational movement, the connecting member consisting of the second outer cylinder 30b, the first outer tube 30a, and the cabtire cable 32b does not rotate, and twisting of the connecting member is prevented. You. Such twisting of the connecting member is likely to occur when circumferential vibration is applied as in the case of the second vibrated body 11, but slight twisting also occurs when radial vibration is applied. In such a case as well, there is a benefit of arranging the second vibrating body 11 rotatably with respect to the second outer cylinder 30b.

The first brush 2 is constructed by mounting a plurality of ring-shaped brush holders 21 on the first vibrating member 1 having a cylindrical shape. The first brush 2 can also be configured by spirally winding the brush material 22. Further, the first brush 2 or the second brush 12
Of the brush material 22 is tilted in any of the front and rear directions from a direction orthogonal to the traveling direction, and the first
The brush 2 or the second brush 12 may be configured to run on its own.

FIG. 10 shows another example of the structure of the first vibration generating mechanism 3, in which substantially the same parts as those in the previous embodiment are denoted by the same reference numerals. In this structural example, the first vibration generating mechanism 3 is interposed between the large-diameter portion 15b in the middle of the shaft member 15 and the first vibrating member 1 '. That is, a pair of support members 7a are screwed into the first vibrating body 1 'to which the first brush 2 is fixed, and half of a steel ball as the protrusion 7 is rollably embedded in each support member 7a. Each of the projections 7 is engaged with a pair of annular grooves 8 formed in the large diameter portion 15b of the shaft member 15. The shaft member 15 is provided with a sliding bearing 4 at the tip instead of the rolling bearing 40 of the above embodiment.
It is rotatably supported on the inward flange-like member 1b of the first vibrating member 1 'via the 0' so as to be slightly movable in the direction of the center axis, and the male screw portion 15a at the tip of the shaft member 15 is omitted. It is. The shaft member 15 is supported by a rolling bearing 41 'at the tip end of the second vibrating member 11' so as to be rotatable and immovable in the center axis direction, instead of the sliding bearing 41 of the above embodiment. .

According to this structural example, the large-diameter portion 15b having the annular groove 8 is rotated by the rotation of the shaft member 15, but the shaft member 15 is supported by the rolling bearing 41 'so as not to move in the center axis direction. while being, this' than is engaged with the protrusion 7 formed on the first driven member 1 'annular groove 8 is first driven member 1 slide bearing 40' is guided by the 42 central Vibrated in the axial direction. Thus, the same operation as the above embodiment can be obtained. The same effect can be obtained even if the protrusion 7 is formed on the shaft member 15 side and the annular groove 8 is formed on the inner peripheral surface of the second vibrating member 11 'and is inclined from a direction perpendicular to the center axis.

In the above embodiment, the eccentric rotary pendulum 13a is provided as the second vibration generating mechanism 13 and driven by the electric motor 32. However, various vibration generating mechanisms are employed, and the air motor is used. Accordingly, the vibration direction of the second vibrating member 11 is not limited to the circumferential direction, and substantially the same cleaning action can be obtained by giving vibrations in all directions such as an axial direction, a radial direction, and a tangential direction. be able to. However, in the case of the pneumatic second vibration generating mechanism 13, the cabtire cable 32b, which is a connecting tool, is a double air hose for sending and discharging compressed air, and the power supply 60 is an air source.

The cylindrical inner surface 5 is not limited to a circular cross section but may have a rectangular cross section. When the cylindrical inner surface 5 has a rectangular shape, each of the brush materials 2 of the first brush 2 and the second brush 12 may be used.
Gives a contour that also fits 2.

[0041]

As will be understood from the above description,
According to the present invention, it is possible to obtain a cylindrical inner surface cleaning device having a vibration generating mechanism having a simple structure that applies vibration in the center axis direction to a brush. It is possible to satisfactorily clean a certain cylindrical inner surface, a cylindrical inner surface having a square cross section and the like. In addition, a cylinder having an uneven portion is provided by additionally providing a second vibration generating mechanism for giving vibration in a circumferential direction, a radial direction, or the like, and combining the second brush that vibrates thereby and the first brush that vibrates in the central axis direction. The cleaning condition of the inner surface of the shape is further improved. Furthermore, the brush can be moved more reliably and easily in the axial direction of the inner cylindrical surface than when cleaning is performed by applying a rotation to the brush, and a mechanism that supports the rotation reaction force is not required and the structure is simple. is there.

Further, if the outer cylinder and the vibrating body are relatively rotatably fitted to each other with a bearing interposed therebetween, twisting of the outer cylinder connecting the vibrating body and the rotary drive source can be prevented. In addition, damage to the outer cylinder is eliminated.
