Next, the lower left of the tunnel side walls of the vertical tunnel sidewalls wua (Figure 10 of the traveling lane L ₁ side of the inbound lane WU
The procedure for cleaning the a reference) in the second cleaning brush unit BU ₂ with reference to the illustration of flowchart and Figure 16 in FIGS. 12 and 13 will be described. At this time, the second sweeper V ₂ having a second cleaning brush unit BU ₂ shall perform cleaning while traveling in the front from the back side of the paper surface of FIG. Incidentally, sloping tunnel sidewall WUb is cleaned by the third cleaning brush unit BU _3.

When the cleaning operation is not performed, the second cleaning brush unit BU ₂ is stored in the space above the couplers ₂ and 3 connecting the first cleaning vehicle V ₁ and the second cleaning vehicle V ₂ ( 1 and 2). At this time, the lifting frame 40 is at the raised position, the slide frame 42 is sliding to the right side of the vehicle body, and the turning arm 62 is
There clamp pins 64 _L so as to face the left side of the vehicle body is clamped in the clamping means 65 _L (see FIGS. 4 and 5). Also, when storing the second cleaning brush unit BU _2, slide the slide frame 42 on the left side of the vehicle body,
And may be the cleaning brush 71 to clamp the pivot arm 62 by clamping pins 64 _R and clamping means 65 _R so as to face the right side of the vehicle body. Left and right pivoting of the pivot arm 62, the clamping by the clamp means 65 _L, 64 _R is performed manually.

As described below, the second cleaning vehicle V
_In order to clean the tunnel side wall WUa on the traveling lane side of the up lane while traveling from the back side of the drawing of FIG. 10 to the front side, the second cleaning brush unit BU ₂ is previously set in the latter state (the slide frame 42 is The swivel arm 62 is slid to the left side of the vehicle body and the cleaning arm 71 is clamped so that the cleaning brush 71 faces the right side of the vehicle body.

First, a power switch (not shown) is closed (step S1), and an up lane / down lane selection switch 106 is set.
To select the "up lane" (step S2),
"Running lane" is selected by the passing lane selection switch 107 (step S3), and then the overhang / storage selection switch 10 is selected.
When "overhang" is selected in step 8 (step S4), the swing cylinder 82 operates. As a result, the lower portion of the cleaning brush 71 swings so as to approach the tunnel side wall WUa and the upper portion separates from the tunnel side wall WUb, and the swing angle detected by the swing angle sensor 112 reaches a preset stored value. It stops in the state (steps S5, S6 and arrow a in FIG. 16).

Then, the slide frame 42 is slid to the right side of the vehicle body by the slide motor 53 so that the cleaning brush 7
1 is moved in parallel to the tunnel side walls WUa and WUb, and stopped when the slide position detected by the slide position sensor 111 reaches a preset storage value (step S).
7, S8 and FIG. 16 arrow b). Subsequently, the lifting frame 40 is lowered by the lifting cylinder 46 to move the cleaning brush 71 downward in parallel, and is stopped when the intermediate position detection limit switch 110 is turned on (steps S9 and S9).
10 and FIG. 16 arrow c).

Next, the cleaning brush 71 is again moved in parallel to the tunnel side walls WUa and WUb until the slide position detected by the slide position sensor 111 reaches a preset storage value (steps S11 and S12 and FIG. 16).
Arrow d), the cleaning brush 71 reaches the position facing the tunnel side wall WUa and the lowering position detection limit switch 109
The cleaning brush 71 is again translated downwardly until is turned on (steps S13, S14 and arrow e in FIG. 16). Subsequently, the cleaning brush 71 is swung in the opposite direction to the above until the swing angle detected by the swing angle sensor 112 reaches a preset stored value, and the cleaning brush 71 is set in a vertical posture parallel to the tunnel side wall WUa. Return (Steps S15 and S16)
And FIG. 16 arrow f).

Finally, the slide position sensor 111
The cleaning brush 71 is again turned on the tunnel side walls WUa, WU until the slide position detected in the step reaches a preset memory value.
When the cleaning brush 71 is moved in parallel to the side b, the cleaning brush 71 abuts evenly on the lower tunnel side wall WUa to be cleaned (steps S17, S18 and arrow g in FIG. 16). And Thus, by injecting wash water second sweeper V ₂ while traveling to rotate the cleaning brush 71 at cleaning brush motor 74, and the washing water nozzle 86 ... from that to clean the tunnel sidewalls WUa it can. The slide motor 53 and the swing cylinder 82 can be operated by an operation lever (not shown).
When the operator operates the operation lever while visually confirming the position of the cleaning brush 71, the contact state of the cleaning brush 71 with the tunnel side wall WUa can be finely adjusted.

[0035] Having described the procedure for cleaning the tunnel sidewalls WUa of lower traffic lane L ₁ side of the inbound lane, that lower tunnel sidewall WUa the overtaking lane L ₂ side is also cleaned by the same procedure it can. However, in the case where the second sweeper V ₂ from the back side of the sheet of FIG. 10 for cleaning while traveling on the front side, the cleaning brush 71 is a pivot arm 62 to pivot in the opposite direction by a manual operation so as to face the left side of the vehicle body Need to be clamped.

Next, the left tunnel sidewall W of the tunnel side walls WUC (11 inclined in the traveling lane L ₁ side of the down lane
The procedure for cleaning the reference bottom) of Uc in the second cleaning brush unit BU _2, will be described with reference to the illustration of flowchart and Figure 17 of FIG. 14 and FIG. 15.

Since the entire tunnel side wall WUc of the down lane is inclined, the cleaning brush 71 is attached to the tunnel side wall WUc.
The tunnel side wall WU in a state of being inclined along the inclination of
abuts on c. Therefore, the flowchart in this case is:
Step S in the flowchart for cleaning the tunnel side wall WUa of the up lane described with reference to FIGS. 12 and 13.
15, S16 (that is, the cleaning brush 7
1 is returned to the vertical position again (step f in FIG. 16), and the other steps are substantially the same. Thus, the cleaning brush 71 can be evenly brought into contact with the inclined tunnel side wall WUc. The “up lane” in step S2 of the flowchart of FIG. 12 has been changed to the “down lane” in step S2 of the flowchart of FIG.

The lower part of the tunnel side walls WUc the overtaking lane L ₂ side of the outbound lane can also be cleaned in the same procedure as the lower part of the tunnel side walls WUc the traffic lane L ₁ side as described above. However, in the case where the second sweeper V ₂ from the back side of the paper surface of FIG. 11 for cleaning while traveling on the front side, the cleaning brush 71 is a pivot arm 62 to pivot in the opposite direction by a manual operation so as to face the left side of the vehicle body Need to be clamped.

The procedure for moving the cleaning brush 71 from the cleaning position to the storage position can be performed in a procedure reverse to the procedure for moving the cleaning brush 71 from the storage position to the cleaning position.

Thus, even when the upper portions of the tunnel side walls WUb and WUc are inclined toward the center of the tunnel T, the cleaning brush 71 is moved laterally and lowered stepwise to move from the storage position to the cleaning position. Accordingly, the cleaning brush 71 can be moved to the cleaning position while avoiding interference between the upper end of the cleaning brush 71 and the upper portion of the tunnel side wall WUb or the tunnel side wall WUc. In particular, the cleaning brush 71 is inclined so as to follow the inclination of the tunnel side walls WUb and WUc, and is laterally moved and lowered in a stepwise manner, thereby effectively eliminating interference between the upper portion of the cleaning brush 71 and the tunnel side walls WUb and WUc. Can be avoided.

Also, when not in use, the second cleaning brush unit BU ₂ is stored in the space above the couplers ₂ and 3 connecting the first cleaning vehicle V ₁ and the second cleaning vehicle V _2. It is not necessary to secure a storage space for the second cleaning brush unit BU ₂ on the top 14, so that the second cleaning vehicle V ₂ can be reduced in size, and the cleaning brush 71 can be used without interfering with the couplers 2 and 3. The diameter can be increased, so that even if there are protrusions on the tunnel wall surfaces WUa, WUc, the cleaning brush 71 can be hardly caught. Further, the cleaning brush 71 moves left and right from the storage position above the couplers 2 and 3 and then descends and contacts the tunnel wall surfaces WUa and WUc. Therefore, the cleaning brush 71 cleans the left and right tunnel wall surfaces WUa and WUc in the traveling direction. Not only can be cleaned, but also the tunnel wall surfaces WUa and WUc at a position lower than the couplers 2 and 3 can be cleaned.

Further, the second cleaning truck V_TwoDirection of travel

can do.

Now, as shown in FIG. 18A, the rail R and the tunnel side wall W laid in the observer passages P ₁ and P _2.
Ua, the distance between the WUc is set to a constant distance regardless of the straight portion or curved portion of the tunnel T, the front truck 15 of the second sweeper V ₂ to be guided by the rails R at the curve portion of the pair The axes of the driving wheels 18, 18 coincide with the radial directions of the curves of the rail R and the tunnel side walls WUa, WUc. Thus, the second cleaning brush unit cleaning brush 71 of BU ₂ supported on a front bogie 15 also tunnel sidewall in curved section of the tunnel T wua,
WUc can be brought into contact with a constant surface pressure.

If the second cleaning brush unit BU ₂ is supported not by the front carriage 15 but by the chassis unit 14 as shown in FIG. The axis is the drive wheel 1
Deviated by an angle α relative to the axis of 8,18, resulting second cleaning brush unit BU ₂ of the cleaning brush 71 is tunnel sidewall wua, the cleaning brush 71 interferes strongly WUc may be damaged . When the tunnel T is curved in the opposite direction to the above-described state, the cleaning brush 71 separates from the tunnel side walls WUa and WUc, so that the contact surface pressure of the cleaning brush 71 decreases and the cleaning effect may decrease. There is. However, according to this embodiment, by the front truck 15 supporting the second cleaning brush unit BU _2, wherein the defect is eliminated.

Although the embodiments of the present invention have been described in detail, various design changes can be made in the present invention without departing from the gist thereof.

For example, instead of driving the lifting frame 40 by the lifting cylinder 46, it can be driven by other means such as an endless chain or a rack and pinion, and the slide frame 42 is driven by the rack 55 and the pinion 54. Alternatively, it can be driven by other means such as an endless chain or cylinder. Further, the swivel arm 62 is not always necessary, and the brush holder 70 may be directly supported on the slide frame 42.

[0047]

As described above, according to the first aspect of the present invention, even if the upper part of the wall surface of the tunnel is inclined toward the tunnel cleaning vehicle, the left-right moving frame moves left and right and the lifting frame descends. The cleaning brush can be moved from the storage position to the cleaning position without causing the cleaning brush to interfere with the upper part of the wall surface of the tunnel.

According to the second aspect of the present invention,
By moving the cleaning brush from the storage position to the cleaning position in a state where the cleaning brush is inclined along the inclination of the wall surface of the tunnel, the interference between the cleaning brush and the upper part of the wall surface of the tunnel is effectively eliminated while effectively eliminating the interference. The cleaning brush can be quickly moved from the storage position to the cleaning position.
