Description

Description: TECHNICAL FIELD The present invention relates to a cleaning device used for cleaning brake shoes and the like of an automobile.

[Conventional technology]

Taking an automobile as an example, it is preferable to wash the brake shoes from time to time because dust accumulates as the brake shoes are repeatedly used and this causes a malfunction of the brakes.

Conventionally, as a device for cleaning a brake shoe of a vehicle, a brake shoe removed from the vehicle is supported on a shaft, and a cleaning liquid is applied to the shaft by a manual nozzle, and an observation window is provided for the brake shoe removed from the vehicle. 2. Description of the Related Art There is known a device which is housed and supported in a drum and blows air to a brake shoe while observing from a window with a manual nozzle inserted into the drum.

[Problems to be solved by the invention]

However, the former method has a problem that the efficiency is extremely poor because the cleaning is almost performed by hand, and the cleaning liquid is liable to be scattered to the surroundings together with the washing waste. The latter is extremely poor in work efficiency because the brake shoes housed in the drum are blown and cleaned by a manual nozzle inserted into the drum from outside the drum, and the drum observation window is also covered with dust, which is also extremely inefficient. There is a problem.

In addition, both devices are cumbersome because the brake shoes must be removed from the vehicle once.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cleaning device that can be used for cleaning automobile brake shoes and other articles, and can easily and efficiently clean brake shoes without removing the brake shoes from the automobile. And

[Means for solving the problem]

The present invention solves the above problems, one end is opened,
A cylindrical cover having the other end closed; a rotating member disposed in the cover and rotatably supported by the cover; a means for rotating the rotating member; and a swing provided on the rotating member. A slider crank mechanism; a transmission device between the rotating member and the crank section for rotating a crank section of the mechanism in conjunction with the rotation of the rotating member; and a slider fixed to the slider section of the mechanism and swinging the slider. A nozzle support arm that reciprocates between a peripheral portion and a center portion of the cover in conjunction with movement; a cleaning liquid injection nozzle supported by the arm; and a cleaning liquid supply pipe extending from the nozzle to outside the cover via a rotary joint. Means, and a cleaning device, comprising:

The nozzle may be restricted in direction by means for restricting the direction of the nozzle so that the nozzle is directed in a predetermined direction along with the reciprocating operation.

Further, the cover may be provided with cover setting means for supporting the cover and disposing it at a predetermined position, so that the cover can be set at a predetermined position, for example, at a portion of an automobile brake shoe.

(Operation)

According to the cleaning device of the present invention, for example, when taking brake shoe cleaning as an example, the brake shoes on the automobile are exposed,
If necessary, cover the bearing portion with a cover, and then fit the open end of the cylindrical cover to the brake shoe.

Next, while supplying the cleaning liquid through the cleaning liquid supply pipe means, the cleaning liquid is injected from the cleaning liquid injection nozzle and is applied to a brake shoe. On the other hand, the rotating member is rotated by the driving means. Then, with the rotation of the rotating member, the nozzle rotates along with the arm that supports it, the swing slider crank mechanism, and the like along the brake shoe. Due to this rotation, the crank portion rotates by the action of the transmission device between the crank portion and the rotating member in the mechanism, the slider portion swings as the crank portion operates, and the nozzle support arm and the nozzle support arm as the slider swings. The nozzle reciprocates between the peripheral portion and the central portion in the circular cover, and the cleaning liquid is applied to the entire brake shoe.

The reciprocating operation of the nozzle is faster in a certain range of rotation of the crank portion and slower in other ranges in accordance with the principle of the swing slider crank mechanism, when the rotation speed of the crank portion is constant.

When washing is completed, the tubular cover is removed from the brake shoe.

When cleaning an article other than the brake shoe, the article may be covered with the tubular cover, and cleaned in the same manner as the brake shoe.

When the nozzle direction regulating means is provided, the cleaning liquid can be more accurately applied to the object to be cleaned irrespective of the reciprocating operation of the nozzle.

Further, when the cover setting means is provided, the cover can be easily put on the object to be cleaned.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Although the illustrated embodiment is suitable for cleaning brake shoes for automobiles, it can also be used for cleaning other items.

Each arm 32 has a tip connected to the cover 1 by a bolt 321. The bolt 321 penetrates the fulcrum member 13 with the long hole 131 fixed to the side surface of the cover 1 and is screwed to the nut 322 on the back side. The position of the bolt 321 substantially coincides with the axis passing through the center of gravity of the cover 1 and the entire components assembled thereto.

When the handle 21 on the gantry 2 is rotated by the above configuration, the worm gear 22 rotates and the worm wheel 23 rotates, so that the arm 3 fixed to the wheel shaft and the arms 32, 32 connected to the arm 3 swing. Go up and down. The cover 1 also moves up and down as the arm 32 moves up and down. The cover 1 can adjust its direction by swinging up and down in the direction of arrow A in FIG.

Next, as shown in FIG. 4, a disc-shaped rotating member 4 is disposed in the inner part of the cover 1, and the member has a central axis.
It is rotatably supported by a bearing 121 on the closing wall 12 of the cover 1 via 41.

An oscillating slider crank mechanism 5 is provided in a part around the rotating member 4.

The mechanism 5 includes a disk-shaped crank portion 51 rotatably supported by a frame 50 fixed to the rotating member 4, a pin link 52 having a circular cross section standing upright on the crank portion 51, and the pin link sliding. Slider section 53 having elongated hole 531 that fits freely

It is connected so that it can swing around 2.

A switch actuating piece 54 is fixed to the crank part 51, and switches 55 and 56 for switching the rotation direction of a motor 71, which will be described later, are arranged on a circular orbit of the actuating piece. It is supported by the cover 1 via a member.

The crank 51 rotates slowly with the rotation of the rotating member 4 under the action of the transmission 6. The transmission 6 includes a crank 51
A worm gear wheel mechanism 61 connected to the rotary shaft of the rotary member 4 and a belt transmission 62 connecting the mechanism to the shaft 41 of the rotary member 4. In the present example, the crank part 51 is configured to make substantially one rotation when the rotating member 4 makes 21 rotations.

The rotating member 4 is driven to rotate by a driving device 7. The device 7 has a motor 71 provided on the cover 1 and a rotation of this motor as an axis.
And a belt transmission 72 for transmitting to 41.

A part of the slider portion 53 is loosely fitted in a hole 42 provided in the rotating member 4, and an arm 8 passing through the hole 42 is cantilevered to the portion.

Therefore, the arm 8 can also be swung by the swing of the slider portion 53, whereby the tip of the arm 8 can reciprocate in the cover radial direction between the peripheral portion and the central portion inside the cover 1.

A cleaning liquid injection nozzle 9 is rotatably supported at the tip of the arm 8.

The nozzle 9 is provided with a nozzle direction regulating device 10. This device 10 includes two long and short links 102 and 103 rotatably connected to the shaft of a free-running roller 101, the long link 102 being rotatable on the nozzle 9 and the short link 103 being rotatable on the arm 8, respectively. It is connected to. The link 103 is also connected to the arm 9 by a coil spring 104.

According to this device 10, as the arm 8 swings from the outermost position shown by the solid line in FIG. 4 to the center side of the cover 1, the roller 101 comes into contact with the rotating member 4, and then the member It rolls along cover 4 toward the center of the cover. Then, the long link 102 pushes the nozzle 9 to rotate the nozzle in a predetermined direction. When the arm 8 returns to the periphery of the cover, the spring 104 pulls the short link 103 toward the arm 8, so that the long link 102
By pulling to the side, this causes the nozzle direction to return to its original orientation.

A cleaning liquid is supplied to the nozzle 9 by a cleaning supply pipe device 90. That is, a flexible pipe 91 is connected to the nozzle 9, and this pipe is further connected to an end of a hole 92 provided in the shaft 41 of the rotating member 4. The other end of the hole 92 is connected to a rotary joint 93, to which a flexible pipe 94 is connected. The pipe 94
Is further connected to a pump 95 on the gantry 2. This pump is driven by a motor 96 via a belt transmission 97 to pump up a cleaning liquid in a tank (not shown),
4, rotary joint 93, hole 92 of shaft 41 and pipe 91
The cleaning liquid can be supplied to the nozzle 9 through the nozzle.

Here, the mechanism 5 and the transmission device 6 will be further described. These components are configured so that the respective components obtain the following operating relationship. That is, in the state shown in FIG. 4, the slider portion 53 is at the position where
The pin link 52 on 51 is in position P1, and the nozzle 9 is at the outer position closest to the inner wall of the cover 1. From this state, when the crank 51 rotates two-thirds in the counterclockwise direction or one-third in the clockwise direction and the pin link 52 takes the position P2, the slider part 53 swings rightmost. And the nozzle 9 takes the position closest to the center of the cover 1. Pin 52 moves counterclockwise from position P1 to P2 or from position P2 to P1
During two-thirds of a clockwise rotation, the rotating member 4 is approximately 14
It is designed to rotate. The rotating member 4 is configured to make approximately seven rotations while the pin 52 makes a one-third rotation clockwise from the position P1 to P2 or counterclockwise from the position P2 to P1. Further, according to the principle of the swing slider rank mechanism, while the pin 52 rotates counterclockwise from the position P1 to P2 by two-thirds from the position P1 with the rotation of the crank 51, the slider 53 is relatively moved. The nozzle 9 swings slowly, so that the nozzle 9 also moves relatively slowly, so that the object to be cleaned can be thoroughly cleaned. Further, while the pin 52 rotates clockwise from the position P1 to the position P2 by the rotation of the crank portion 51 or one third of the rotation from the position P1 to the reverse, the slider portion 53 swings relatively quickly. The nozzle 9 also moves quickly, so that the object to be cleaned can be cleaned relatively coarsely, but quickly.

According to the cleaning device, for example, in the case of the brake shoe cleaning of an automobile, if necessary, a known cleaning liquid preventing cover C is provided on the exposed bearing portion b of the brake shoe B on the automobile. Fit, then,
The open end 11 of the cover 1 is externally set on the brake shoe. In this case, the cover 1 is set by adjusting the height of the cover 1 as the arms 31 and 32 move up and down by manually rotating the handle 21 on the gantry 2 and moving the gantry 2.

Next, the pump 95 on the gantry 2 is operated to send the cleaning liquid to the nozzle 9, and the cleaning liquid is ejected from the nozzle. By operating the motor 71 on the cover 1 before and after this, the rotating member 4 in the cover 1 is rotated.

The crank portion 51 and the link 52 of the swing slider crank mechanism 5 rotate with the rotation of the rotating member 4, and the slider portion 53 swings with the rotation of the pin. Further, the nozzle support arm 8 swings in accordance with the swing of the slider portion 53, whereby the nozzle 9 moves between a position near the periphery in the cover 1 and a position near the center. The nozzle 9 naturally rotates along with the brake shoe B with the rotation of the rotating member 4, and the nozzle 9 moves in the radial direction of the cover 1 as described above. You. When the nozzle 9 is quickly moved in the radial direction of the cover 1 in this cleaning, the pin 52 of the swing slider crank mechanism 5 is reciprocated in the clockwise direction in FIG. 4 or in the opposite direction from the position P1 to P2. This reciprocating rotation can be performed by turning the switches 55 and 56 on the switch activation piece 54 on the crank 51 so that the motor 71
This is performed by switching the rotation direction of. Cover the nozzle 9 1
If it is desired to perform elaborate cleaning by slowly moving in the radial direction, the motor 71 may be operated so as to reciprocate the pin 52 of the mechanism 5 from the position P1 to the position P2 in the counterclockwise direction or in the opposite direction. . This reciprocating rotation switching is also performed by the activation of the switches 55 and 56 by the switch activation piece 54.

When the cleaning of the brake shoes B is completed in this way, the gantry 2 is retracted, and the cover C is removed from the brake shoe bearing b.

The cleaning liquid jetted into the cover 1 can be recovered to a predetermined position by a recovery hose (not shown) connected to the cover 1.

The case where the brake shoe B is cleaned has been described above as an example, but the cleaning device can also be used for cleaning other articles. For example, the object D to be cleaned may be arranged on the lower portion 2A of the gantry 2 and the cover 1 may be placed on the object D with its open end 11 facing downward. Such a posture of the cover 1 can be obtained by rotating the cover 1 about the bolt 321 with respect to the arm 32 and adjusting the height of the cover 1 by moving the arms 3 and 32 up and down. In the gantry part 2A, if necessary,
A not-shown collection hose or the like may be provided.

When the cleaning device is not used, the arms 3 and 32 are raised, and the cover 1 may be placed on the rear half 2B of the gantry 2 as shown by a two-dot chain line in FIG.

It should be noted that the present invention is not limited to the above-described embodiment, and can be implemented in various other modes.

For example, a motor for rotating the rotating member 4 in the cover 1
71 can be replaced with a manual handle, and a manual handle for raising and lowering the arms 3 and 32 supporting the cover 1
21 can be replaced by an electric motor. Further, the nozzle direction restricting means is not limited to the above-described embodiment apparatus 10, but may be another mode, for example, a belt or a rope may be wound around a pool provided in the nozzle 9, and both ends of the belt or the rope may be rotated. 4 can be considered.

In addition, if warm water is used as the washing water, drying can be accelerated. If two types of covers 1 are prepared, one for large-sized and one for medium-sized, it is possible to respond to a change in model.

〔The invention's effect〕

As described above, according to the cleaning apparatus of the present invention, it can be used for cleaning automobile brake shoes and other articles, and the object to be cleaned can be coarsely but quickly, or slowly and carefully as required. It is possible to easily and efficiently perform the cleaning as compared with the brake shoe cleaning device and the like described above, and it is possible to clean the brake shoe without removing it from the automobile, and thus easily.
