BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tunnel interior plate cleaning device.

[0002]

2. Description of the Related Art An interior plate, which has an arcuate vertical cross section and is disposed along the side wall surface of a road tunnel, is contaminated by exhaust gas of an automobile and must be cleaned at regular intervals. In the past, however, a lane on one side of the tunnel was closed, and in the closed lane, a vehicle having a large rotating brush in contact with the interior plate and a pump and tank for spraying water and detergent on the interior plate were installed. The cleaning work was carried out by running the above vehicle and washing off the dirt on the interior plate with the rotating brush, water and detergent.

[0003]

However, when the cleaning work is performed as described above, one lane in the tunnel is closed, which causes traffic congestion and a rear-end collision may occur on the highway. There was also. Further, since the dirt is washed off with water and detergent, there is a problem of environmental pollution around the tunnel.
Further, there is a problem that a large number of workers are required because extra workers are required for safety confirmation and driving of the vehicle.

Therefore, the present invention solves the above-mentioned problems, and provides a tunnel interior plate cleaning device capable of automatically cleaning the interior plates with a small number of people without regulating the lanes in the tunnel. The purpose is to do.

It is another object of the present invention to provide a tunnel interior plate cleaning device which can clean the interior plate without damaging the environment around the tunnel.

[0006]

In order to achieve the above-mentioned object, a tunnel interior plate cleaning apparatus according to the present invention is a tunnel for cleaning interior plates having an arc-shaped cross section arranged along the side wall surface of the tunnel. An interior plate cleaning device, comprising: a vertical support frame part whose upper end is guided and guided by an upper rail; an arcuate vertical frame part disposed between the vertical support frame part and the interior plate; A lower frame part disposed near the lower end part of the frame part and movably attached to a lower rail laid parallel to the upper rail on a side of the tunnel such as a guardian's passage or / and a passage of an inspection corridor And a rotating frame that is in contact with the surface of the interior plate, and a rotation drive mechanism that rotationally drives the rotating brush.

It is also preferable that the rotary brush is rotatable about an axis substantially parallel to a tangent line contacting the inner surface in the cross-sectional shape of the interior plate. It is also desirable that the rotary brush is rotatable about a horizontal axis substantially parallel to the upper and lower rails, and the rotary brush is vertically movably attached to the arcuate vertical frame portion of the traveling frame body.

The rotary brush is attached to the traveling frame so that it can be moved toward and away from the interior plate, and the rotary brush is removed from the interior plate by a signal from a sensor that detects the position of a protrusion protruding from the interior plate. It is also preferable to provide projection avoiding means for separating the projections to avoid the projections.

Further, the rotating brush is attached to the arcuate vertical frame portion of the traveling frame body so as to be movable up and down, and a signal from a sensor for detecting the position of a protrusion protruding from the interior plate or a signal from a manual input device is used. It is also desirable to provide height adjusting means for adjusting the height of the rotating brush.

It is also desirable to provide a dust collecting device having a dust collecting cover that is open to the interior plate side and has a rotating brush projectingly arranged in the opening.

[0011]

[Action]

(According to claim 1) Since the upper end of the vertical support frame portion of the traveling frame body is guided and guided by the upper rail, the rotating brush attached to the vertically long traveling frame body is brought into contact with the interior plate of the tunnel. Also, it is possible to prevent the traveling frame body from falling to the side of the roadway. Also,
Since the running frame runs on the passage on the side of the tunnel (passenger passage or inspection corridor), this device does not protrude into the lane inside the tunnel. Moreover, since the traveling body travels along the upper rail and the lower rail, the traveling can be easily automated.

According to the second aspect, the rotating brush can be brought into contact with the surface of the interior plate over the entire width in the axial direction. By running the traveling frame while rotating the rotary brush, the interior plate surface can be laterally cleaned over the entire width of the rotary brush in the axial direction. If the rotating brush is provided so as to cover the entire height of the interior plate, the entire interior plate on one side in the tunnel can be cleaned by one traveling.

According to the third aspect of the present invention, the rotary brush is brought into contact with the surface of the interior plate, and the rotary brush is moved upward or downward while being rotationally driven. The interior plate surface can be cleaned in a substantially vertical direction. While rotating the rotating brush to move it up and down,
The entire surface of the interior plate can be cleaned by traveling the traveling frame body continuously or intermittently.

(According to claim 4) When the traveling frame moves forward and the sensor detects the position of the protrusion, the rotating brush which is rotating while being in contact with the interior plate comes out of the interior plate before hitting the protrusion. Avoid the protrusions away. Immediately after passing over the protrusion, the rotary brush comes into contact with the interior plate to clean the interior plate. Therefore, the rotating brush does not hit the protrusions and the interior plate is not wiped.

(According to claim 5) When the traveling frame moves forward and the sensor detects the position of the protrusion, the rotary brush moves upward or downward while rotating in contact with the interior plate and protruding. Avoid things. Therefore, the rotating brush does not hit the protrusions and the interior plate is not wiped.

Since the rotary brush is arranged at the opening of the dust collecting cover (according to claim 6), the dust and carbon fine substances wiped off the interior plate surface by the rotary brush are collected. It is completely sucked from the opening of the dust cover and stored in the dust collector. Therefore, the stains once wiped from the interior plate do not adhere to the interior plate again or fall downward, and it is not necessary to wash the interior plate with water or detergent.

And rack portions 37, 37 for operating.

Further, the rotating brush 17 is attached to the traveling frame body 8 so as to be able to approach and separate from the interior plate 2. Specifically, the dust collecting cover 23 holding the upper rotating brush 17a is attached to the attachment lifting member 35 via the lateral slide mechanism 39 driven by the air cylinder 40.

In this interior plate cleaning device, however, the rotary brushes 17 are separated from the interior plate 2 by the signal from the sensor 41 for detecting the position of the protrusion X protruding from the interior plate 2 to avoid the protrusions. A protrusion avoiding means A is provided.

Here, the projection X means, as shown in FIG. 7, a display plate (indicator light) X ₁ provided so as to project from the interior plate 2 of the tunnel, a fire hydrant storage box X ₂ , and a telephone box. Refers to protrusions such as switchboards. Then, according to the projection avoidance means A, furnished as fire hydrants magazines X ₂ plate 2

It is also desirable to make the 43 portable. By doing so, there is an advantage that the operator can operate the apparatus from a safe place.

The operation and effect of this tunnel interior plate cleaning device will be described. As shown in FIG. 6, the rotary brush 17 is driven to rotate about the axis L ₁ while contacting the surface of the interior plate 2. Then, the surface of the interior plate 2 is cleaned.

As a result, the surface of the interior 2 can be cleaned over the width of the rotary brush 17 in the direction of the axis L ₁ .

At this time, the dust collector 24 is activated,
Minute substances such as dust and carbon wiped off by the rotating brush 17 enter the cover 23 through the opening of the dust cover 23, and then pass through the duct 25 into the dust bag of the dust collector (not shown). Be accommodated.

Therefore, it is possible to prevent the wiped-off minute substances from adhering again to the interior plate 2 or dropping downward to remain in the tunnel, and it is not necessary to use water or detergent. Therefore, there is an advantage that there is no risk of environmental pollution in and around the tunnel.

By the way, the lower end of the upper rotating brush 17a is set to a height slightly lower than the upper end of the middle rotating brush 17c, and the lower end of the middle rotating brush 17c is set to the lower rotating brush 17c.
The height is set to be slightly lower than the upper end of b. Further, the upper end of the upper rotating brush 17a is set at a position substantially the same as the upper end of the interior plate 2, and the lower end of the lower rotating brush 17b is set at a position substantially the same as or slightly higher than the lower end of the interior plate 2. .

Therefore, the upper rotary brush 17a, the middle rotary brush 17c, and the lower rotary brush 17b correspond to the ranges indicated by a, c, and b in FIG. 7, respectively. That is, the entire height of the interior plate 2 can be covered by the three rotating brushes 17 ...

Therefore, as shown by the arrow C in FIG. 1, the interior frame 2 can be cleaned over the entire height only by moving the traveling frame 8 forward at a predetermined speed, and the workability is extremely high.

Further, the bar code showing the position, size, protruding size, etc. of the fire hydrant storage box X ₂ shown in FIG. 7 is shown in FIG.
When the sensor 41 shown in (1) reads, the corresponding rotating brush 17 is separated from the interior plate 2 at the position immediately before the fire hydrant storage box X ₂ . That is, the middle rotating brush 17c and the lower rotating brush 17b corresponding to the ranges c and b in FIG. 7 are separated from the interior plate 2 as shown in FIGS.

[0052] Thus, the rotary brush 17 hits the hydrant storage box X ₂ is not possible to prevent damage to the apparatus and hydrants storage box X _2. That is, the fire hydrant storage box X ₂ is the interior plate 2
Since the protruding size from the
The fire hydrant storage box X ₂ can be sufficiently avoided only by separating it from

Further, according to the data obtained from the bar code,
Medium rotating brush 17c and the lower rotary brush 17b is, respectively, it rotated with contacting the interior panel 2 at the time beyond the hydrant storage box X _2, go wipe the surface of the interior panel 2 again.

Next, the display plate (indicator light) X ₁ shown in FIG.
The bar code that displays the position, size, protruding size, etc. of
Reads a sensor 41 shown in FIG. 1, at a position immediately before the display panel (display light) X _1, and moves the corresponding upper rotary brush 17a is downward, the upper rotary brush 17a is panel (indicator) Avoid X ₁ .

That is, the display plate (indicator light) X ₁ is the interior plate 2
Since the protrusion size from is relatively large, the display plate (indicator light) X ₁ cannot be avoided even if the upper rotating brush 17a is separated from the interior plate 2. Therefore, the upper rotary brush 17a is moved downward to avoid the display plate (indicator light) X ₁ . As a result, it is possible to prevent the device and the display plate (indicator light) X ₁ from colliding and being damaged.

It should be noted that according to the data obtained from the ID code,
Upper rotary brush 17a is at the time beyond the display panel (display light) X _1, abuts in close proximity to the interior panel 2, go wipe the surface of the interior panel 2 again. Also, the height adjustment of the upper rotating brush 17a is
Normally, the operation control means (not shown) is set to be automatically set, but it is also preferable that the operator directly operates the height adjustment using the operation panel 43.

As described above, according to this tunnel interior plate cleaning device, the interior plate 2 can be operated by a smaller number of operators than before.
Interior plate 2 while avoiding protrusions X such as the fire hydrant storage box, display board (indicator light), switchboard, and telephone box that protrude from
The entire surface can be cleaned.

Further, since the present device has only the passage 30 such as a guardian passage on the side of the tunnel and the inspection corridor, it does not obstruct the passage of vehicles in the tunnel and does not have to regulate the lane. . Therefore, it is possible to perform the cleaning work extremely safely and prevent traffic congestion.

Furthermore, the cleaning work can be performed by remote control, and the operation can be automated. In addition, since it is possible to collect all the dust generated by cleaning without using water or detergent, there is no fear of environmental pollution.

Next, FIGS. 8 and 9 show another embodiment,
Two rotating brushes 17, 17 are attached to the front traveling frame 8a, and a rear traveling frame body (not shown) having a generator or the like mounted behind the front traveling body 8a is connected by a connector 9. Has been done.

Therefore, the rotating brushes 17, 17 are rotatable about the horizontal axis L ₂ substantially parallel to the upper and lower rails 3, 6, and the rotating brushes 17, 17 are movable. It is attached to the arcuate vertical frame portions 5 and 5 so as to be vertically movable.

That is, the upper rotating brush 17 is attached to the rear traveling frame 8b.
An elevating mechanism 42 for separately elevating and lowering the d and the lower rotary brush 17e is provided.

The elevating mechanism 42 includes an upper mounting elevating member 35a to which a dust collecting cover 23 for rotatably holding an upper rotating brush 17d having an outer peripheral surface which is straight in the axial direction is attached, and a linear mechanism which is also straight in the axial direction. Lower rotating brush with outer peripheral surface
The lower mounting lifting member 35b to which the dust collecting cover 23b that rotatably holds the 17e is mounted, and the upper and lower mounting lifting member 35b.
a, 35b are pivotally attached to both front and rear surfaces and arcuate vertical frame portion 5,

And the pinion members 38 that are vertically attached to the surfaces of the arcuate vertical frame portions 5 and 5 on the side of the interior plate 2.
And rack portions 37 with which 38 ... mesh with each other.

The dust collecting covers 23, 23 are connected to the suction connecting portion 29 of the dust collector 28 via the duct 25.

Furthermore, this cleaning device has a height adjusting means B, which is mounted on the lower surface of the lower frame portion 7 of the elevating mechanism 42 and the rear traveling frame body 8b.
41, a manual input device (not shown), and operation control means for controlling the drive of the motors 32 of the elevating mechanism 42 by a signal from the sensor 41 or the manual input device.

As shown in FIG. 8, the upper rotating brush 17
Reciprocating movement of d is restricted within a range of substantially vertical direction indicated by H ₁ , and reciprocating movement of the lower rotary brush 17e is restricted within a range of substantially vertical direction indicated by H ₂ . The lower end of the range H ₁ is set lower than the upper end of the range H ₂ . Therefore, the entire height of the interior plate 2 can be covered.

However, when there is no protrusion, the upper and lower rotating brushes 17d and 17e rotate while contacting the interior plate 2,
Moreover, the upper and lower rotary brushes 17d and 17e reciprocate up and down, respectively.

Further, the traveling frame body 8 intermittently advances in the direction indicated by the arrow F in FIG. 9 at a predetermined pitch.

This makes it possible to move forward while cleaning the interior plate 2 over the entire height dimension. Further, the front-rear width dimension W of the traveling frame body 8 can be made small (compact). Therefore, the turning radius becomes small.

When the sensor 41 reads the position, size, protrusion size, etc. of the protrusion, the upper and lower rotating brushes 17d,
The vertical movement width of the upper and lower rotary brushes 17d and 17e is restricted so that 17e does not hit the protrusion. As a result, it is possible to prevent collision and damage of the present device and the projection.

As a traveling method of the traveling frame body 8, in addition to intermittently advancing at a predetermined pitch as described above, it is also possible to continuously travel at a predetermined speed.

The present invention can be modified in design other than the above-mentioned embodiment. For example, in FIG.
If separate running frames 8 are provided for each of a, 17b, and 17c (as a vertically elongated shape) and are connected by a coupler to form a multi-connection type,
The turning radius is small, which is preferable. Further, as shown in FIGS. 1 to 6, in addition to the three rotary brushes 17 which rotate around the axis L ₁ , one or two or four to eight rotary brushes 17 may be freely provided.

Further, as shown in FIGS. 8 and 9, in addition to the two rotary brushes 17 that rotate around the axis L ₂ , one or three to five rotary brushes 17 may be provided.

As the sensor 41, it is preferable to use a photoelectric switch other than the ID sensor. In that case, a plurality of photoelectric switches are provided on the traveling frame 8 side, and an appropriate number of detected protrusions are arranged on the lower rail 6 and the like, and the photoelectric switch is adjusted depending on the number and position of the detected protrusions. Then, the control panel 44 of FIG. 1 identifies the next projection X by giving a difference to the information detected.

The motive power source may be a trolley type in which an overhead wire is provided in the tunnel and current is collected from the overhead wire, in addition to mounting a generator to drive the motor. Alternatively, an internal combustion engine may be mounted on the traveling frame body 8. Also,
A chain may be stretched as the rack portion 37, and the pinion member 38 may be used as a sprocket.

[0076]

Since the present invention is configured as described above,
The following effects are obtained.

According to the tunnel interior plate cleaning device of the first aspect, there is no obstruction to the passage of vehicles traveling on the road in the tunnel, and lane regulation is not required during cleaning. In addition, it can be cleaned by a simple operation by a small number of workers as compared with the conventional method, and the workability is excellent. Moreover, the cleaning work can be automated. In addition, it is extremely safe for both vehicles and cleaners passing through the tunnel.

According to the tunnel interior plate cleaning device of the second aspect, the same effect as that of the first aspect can be obtained, and the interior plate 2 can be sufficiently moved even when the traveling frame body 8 is traveled at a relatively high speed. It can be beautifully cleaned and the cleaning work time can be shortened.

According to the tunnel interior plate cleaning device of the third aspect, the same effect as that of the first aspect is obtained, and the interior plate 2 is curved in an arc shape in the vertical direction. Since the outer peripheral surface of the rotating brush 17 can be made straight in the axial direction, it can be easily manufactured. In addition, the front-rear width dimension W of the traveling frame body 8 (as shown in FIG. 9) can be made small (compact). Therefore, the turning radius can be reduced.

According to the tunnel interior plate cleaning device of the fourth aspect, since the protrusion having a relatively small protruding size, such as the fire hydrant storage box and the switchboard, can be easily and automatically avoided, the present device and the protrusion It can prevent damage to things. Further, the entire surface of the interior plate excluding the protrusions can be cleaned without being wiped.

According to the tunnel interior plate cleaning device of the fifth aspect, not only the protrusion having a relatively small protrusion size but also the protrusion size of the display plate (indicator light) indicating the position of the telephone or the telephone box is compared. Since even a relatively large protrusion can be easily avoided, damage to this device and the protrusion can be prevented. Further, the entire surface of the interior plate excluding the protrusions can be cleaned without being wiped.

According to the tunnel interior plate cleaning device of the sixth aspect, it is possible to prevent scattering of fine substances such as dust and carbon generated during cleaning. Therefore, the inside of the tunnel and the device itself are not contaminated. In addition, all the minute substances can be recovered, and it is not necessary to use water or detergent. Therefore, there is no concern about environmental pollution in or around the tunnel.
