Field of the Invention The present invention relates to a suction-type cleaning work vehicle capable of traveling in a water channel such as a sound channel or an open channel, and more particularly to a suction-type cleaning vehicle that adheres or accumulates on a wall surface of the water channel. The present invention relates to a suction-type cleaning work vehicle that removes water and cleans a wall surface.

[Conventional technology]

As a suction-type cleaning work vehicle that can operate in a water flow such as an intake / drainage channel of a power plant or the like, a two-drum type cleaning vehicle shown in FIGS. 13 and 14 is known. That is, at the tip of the self-propelled vehicle main body of the suction-type cleaning work vehicle, a fixed cylinder 103 rotatably attached to the vehicle main body and connected to the suction pipe 102, and a telescopic cylinder telescopically attached to the fixed cylinder 103 A collection arm 101 consisting of a flexible tube 104 is attached to the distal end of the telescopic tube 104.
A collection mouse 108 containing two cutting drums is attached via a suction trumpet tube 102a.

In the drawing, reference numeral 105 denotes a hydraulic cylinder for moving the recovery mouse 108 toward and away from the wall surface 40 to be cleaned, 106 denotes a mounting base for the recovery mouse, 107 denotes a vertical device, 109 denotes a hood, and 110 denotes a hydraulic motor for driving the recovery mouse. Reference numeral 42 denotes the center of rotation of the recovery arm 101, and reference numeral 41 denotes marine organism deposits such as shellfish and algae.

[Problems to be solved by the invention]

By the way, in such a conventional suction-type cleaning work vehicle,
Cleaning of the wall to be cleaned is performed by rotating the collection mouse 108 along the wall 40 to be cleaned.
It is necessary to continuously perform the posture control by the vertical device 107 so that 108 is perpendicular to the wall surface 40 to be cleaned.

In addition, if a two-drum system and a vertical mechanism are provided, the projected area of the apparatus is inevitably increased, so that the fluid drag is increased and the stability of the working vehicle body in water is deteriorated. In addition, since the vertical mechanism is large, the length from the center of rotation to the top of the recovery arm becomes extremely long in consideration of the amount of expansion and contraction of the recovery arm 101. There is a problem that it may not rotate due to interference.

In addition, since the removed deposits are dissipated outside due to the water current, if a conventional underwater vehicle is diverted to high-speed diversion, the existing deposits will dissipate outside, causing problems such as marine pollution and the effect on power plant equipment. there were.

In particular, at the corner 40a of the culvert, what is removed into the running water is scattered and cannot be collected, so that this place cannot be removed without cleaning.

The present invention is intended to solve such a problem, and the vertical device becomes unnecessary by using one so-called one-drum type cutting drum mounted in the removal / recovery mouse. At the same time, the removal / recovery mouse is attached to the suction pipe so that it can be rotated 180 ° by the reversing mechanism, and the removal / recovery mouse can be rotated in any direction when removing / collecting culvert debris. It is an object of the present invention to provide a suction-type cleaning work vehicle capable of efficiently removing and recovering the adhesion of a culvert surface by always maintaining the same in a removing progress direction.

[Means for solving the problem]

In order to achieve the above object, a suction-type cleaning work vehicle of the present invention includes a self-propelled vehicle main body, a suction pump provided in the vehicle main body, and one end connected to a suction side of the suction pump through a swivel joint. A horizontal portion protruding in the traveling direction from the vehicle body, a fixed cylindrical portion bent from the horizontal portion, and an extension cylindrical portion provided at the distal end of the fixed cylindrical portion so as to extend and contract. Removal / recovery which has a built-in suction pipe and a rotary cutting tool provided at the end of the suction pipe via a second swivel joint to remove an object to be cleaned on the wall surface and has a direction in a cutting advance direction. Mouse and

[Action]

In the suction-type cleaning work vehicle of the present invention, the suction pipe is rotatably supported around the axis of the horizontal part, and the suction pipe is provided with a telescopic mechanism so that the suction part at the tip thereof can move forward and backward toward the wall surface to be cleaned. As a result, the horizontal portion of the suction pipe can be rotated around its axis by the driving device while the removal / recovery mouse attached to the tip of the suction pipe is brought into contact with the wall surface to be cleaned by the expansion and contraction mechanism. The cleaning vehicle can clean not only the floor surface of the water channel but also the side wall surface and the ceiling wall surface.

At this time, the removal / recovery mouse has directionality in the removal progress direction, but every time the suction pipe changes from 0 ° to + 360 °, 0 ° to −360 °, the remove / recovery mouse is inverted by the inversion mechanism, The removal / recovery mouse can always be maintained in the removal progress direction.

In addition, since the one-drum type is used, the rotating drum is brought into contact with the surface to be cleaned by pressing the removing / rotating mouse regardless of the rotational position of the suction pipe to which the removing / collecting mouse is attached. be able to.

The guide rollers 29a and 29b are connected to the drum support 31 by a bearing 29c.
Supported by b.

 The sprocket 19b is attached to one end of the shaft 32.

As shown in FIG. 4, tooth-shaped flat blade cutters 30a to 30n are arranged in a zigzag pattern on the outer periphery of the drum 31. The hydraulic motor 18 provided on the fixed hood top plate 24a drives the sprockets 19a and the chain 20 via the chain 20. The drum 31 is rotated together with the drum 19b so that the attached matter can be removed.

The bearing 21b of the drive shaft 21a is fixed to the fixed part of the swivel joint 14.

The diameter of the guide rollers 29a, 29b is such that the fixed hood bearing 24c, the movable hood bearing 25c, and the sprocket 19b, which are supported by the shaft 32, are positioned above the thickness of the deposit as shown in FIG. Is set to
The collecting mouse 15 does not come into contact with the culvert debris 41 during the removal, and does not become a resistance.

Further, the tooth type flat blade cutters 30a to 30n are fixed at the same pitch with a scooping angle on the drum 31 so as to efficiently remove deposits on the culvert surface. The tooth type flat blade cutter diameter is
The diameter of the toothed flat blade cutters 30a to 30n is set slightly smaller than the diameters of the guide rollers 29a and 29b so as not to damage the cleaning surface.

The diameter of the drum 31 is determined from the tooth-shaped flat blade cutter diameter determined in the above-described procedure, in consideration of a margin for removing attached matter.

Inside the fixed hood top plate 24a on the non-removing side, one or a plurality of crushing fixed teeth 34a and 34b are provided over the entire width of the fixed hood as shown in FIG. And the second
As shown in FIG. 11, the tooth-shaped flat blade cutters 30a to 30n are meshed with the crushing fixed teeth 34a and 34b, and the removed deposits are crushed to a predetermined particle size or less in a suction process. It has become.

In the case where a plurality of fixed grinding teeth are provided, it is necessary to consider the attachment interval so that the moving teeth (tooth flat blade cutters) do not mesh with the fixed grinding teeth at the same time. By doing so, even if there are a plurality of fixed grinding teeth, the grinding torque can be made substantially the same as in the case of a single fixed grinding tooth.

On the other hand, the tooth-shaped impermeable plate 3
5 are provided over the entire width of the fixed hood. The length (l) is set so that six tooth-shaped flat blade cutters can be meshed almost simultaneously. As a result, excess water sucked by passing between the fixed hood 24 and the drum 31 from the removal side is shut off, and the suction effect of the removed matter is increased.

The removal-side front end position of the fixed hood top plate 24a is cut up so that when the suction pipe rotates from one surface to be cleaned to the next surface to be cleaned, it does not come into contact with the adhesion layer on the next surface to be cleaned. The opposite end position on the anti-removal side is the removal / recovery mouse 15
Are formed so that they do not come into contact with the surface to be cleaned even when the removal operation is performed at the greatest inclination.

In the movable hood 25 provided outside the fixed hood 24, the lower end of the movable hood top plate 25a follows the inclination of the removal / recovery mouse 15 and always keeps a small gap with the surface 40 to be cleaned. The removed deposits are sucked and collected without being scattered outside.

Hydraulic motor 27 for driving movable hood 25 on suction wrapper tube 11
Is equipped.

 Symbol H in the figure indicates the thickness of the deposit.

Above the fixed hood top plate 24a of the fixed hood living plate 24b on the anti-removal side is cut so as not to interfere with the operating range of the movable hood top plate 25a as shown in FIG.
Also serves as 25 stoppers.

Rollers 36 also serving as stoppers are provided on both sides of the lower end of the movable hood 25 on the culvert side, so that the movable hood 25 is always positioned at a constant distance from the surface to be cleaned. On the other hand, on the opposite front end, a rack 26 having the same length as the working circumference of the movable hood 25 is provided, and a plurality of rollers 26a are mounted on the rack 26, and the movable hood 24 smoothly rotates along the upper surface of the fixed hood top plate 24a. It is configured to be able to.

The rack 26 is controlled so as to mesh with a gear 28 attached to a hydraulic motor 27 for driving the movable hood, and to rotate the movable hood 25 following the inclination of the removal / recovery mouse.

The movable hood living board 25b is connected to the horizontal part 25d 'at an acute angle with the horizontal part 25d' in order to reduce the resistance of the movable hood living board 25b as it comes into contact with the adhesion layer as the removal and recovery mouse 15 proceeds. The gap between the guide rollers 29a, 29b and the movable hood top plate 25a is substantially closed, so that the removal of the removed material can be eliminated.

In the case of this embodiment, as shown in FIG.
The relationship between the drive device 25 and the fixed hood 24 is a single rack type, but a double rack type is also conceivable.

FIG. 11 is an exploded view of mounting the tooth-shaped flat blade cutter 30 on the drum 31. The tooth-shaped flat blade cutters 30a to 30n are fixed to the outer periphery of the drum 31 in a staggered manner at equal intervals, and the position of the tooth shape is crushed. Fixed teeth 34
It is considered to engage with a small gap corresponding to a and 34b.

As described above, the tooth type flat blade cutter 30 crushes the removed material by the shearing force when it becomes a moving tooth and meshes with the fixed teeth 34a, 34b, and therefore, the crushing fixed teeth 34a, 34b. some cuts leave by some cut leaves provided and h ₂ to h ₁ and the tooth-type flat blade cutter 30A～n, entire tooth type flat blade cutter 30 and grinding stationary teeth 34a, which they and 34b in contact with , So that the shearing effect is further enhanced.

By arranging the tooth-type flat blade cutters in a staggered manner in this manner, the rotating torque is constant on the drum 31 and a smooth movement is possible when removing the adhered substance and pulverizing.

In addition, the three-pitch-length deposits of the removed tooth-shaped flat blade cutter enter the portions C and D at both ends of the drum 31.
In this case, since the powder is sucked without being crushed, it is designed so that a substance having a predetermined particle size or more is not sucked by driving a spike 37 into this place.

With the above configuration, the removed deposits are pulverized to a predetermined particle size or less and sucked, so that there is no risk of a blockage accident in the recovery path.

The mesh between the tooth-shaped water-impervious plate 35 and the tooth-shaped flat blade cutter 30 is also the same.

Next, referring to FIG. 12, one of the movements of the removal / recovery mouse 15 is described.
An example will be described.

When the suction pipe 10 is rotated clockwise about the rotation center 42 from the point 0 ° (a) along the cleaning surface 40 from the point (1) (a), b) up to the point (suction pipe rotation angle = θ
_{In 1} ), the movable hood 25 is operated in the “shrink” direction from the reference position, and is in the maximum “shrink” state at the point (b).

(2) From point (b) to point (c) (suction pipe rotation angle = θ
_{In 2} ), the movable hood 25 is operated from the maximum "retraction" to the "extension" direction, and comes to the reference position at the point (c).

(3) From point (c) to point (d) (suction pipe rotation angle = θ
_{In 3} ), the rotating hood 25 is operated in the “extend” direction from the reference position, and reaches the maximum “extend” at the point (d).

(4) From the point (d) to the point (e) (a position rotated by 90 ° from the point (a)) (the suction pipe rotation angle = θ ₄ ), the movable hood 25 moves from the maximum “extended” to the “contracted” direction. Is moved to the reference position.

Below 90 ゜ -180 ゜, 180 ゜ -270 ゜ and 170 ゜ -36
The above operation is sequentially repeated during 0 °.

On the other hand, at the time of the above-mentioned operation, since the attached matter is removed,
It is necessary to press the removal / recovery mouse 15 against the surface 14 to be cleaned with a predetermined force, which is obtained by the expansion and contraction of the suction pipe 10. The expansion / contraction pattern is “extended” from point (a) to point (b), and “contracted” from point (b) to point (d) →
"Expansion" and "shrinkage" from point (d) to point (e).

By the above operation and the rotation operation of the tooth type flat blade cutter, the adhered matter on the surface to be cleaned can be surely removed, and suction and collection can be performed without dissipating to the outside.

As described above, in the suction-type cleaning work vehicle of this embodiment, since the cutting drum mounted in the removal / recovery mouse is one, the suction pipe 10 to which the removal / recovery mouse 15 is attached can be any type. Even at the rotation position, the removal / recovery mouse can be brought into contact with the surface to be cleaned by pressing the removal / recovery mouse, so that there is no cleaning residue.

Also, the tip of the movable hood 25 of the removal / recovery mouse 15
The hood does not hit the surface 40 to be cleaned even if the suction pipe 10 is rotated to change the posture with respect to the surface to be cleaned, and Since it does not separate from the surface, the removed deposits can be collected without being dissipated.

Further, fixed grinding teeth 34a, 34b provided on the opposite side of the fixed hood 24 of the removal / recovery mouse 15 to the removal side are provided with tooth-shaped spur tooth cutters 3.
With 0 as a moving tooth and both meshing, the removed deposits are crushed to a predetermined size or less, so that pipes, pumps, and hoses in the recovery path are not blocked.

Furthermore, since the tooth-shaped flat blade cutter 30 having a scooping angle on the drum 31 is arranged in a staggered shape with a length divided with respect to the drum width, the removal efficiency is good, and the adherence is sequentially performed by rotating the drum. The tooth type flat blade cutter is removed. In addition, since the grinding fixed teeth 34a and 34b are sequentially meshed with each other to perform a grinding action, the rotation of the drum is constant and a smooth rotation can be obtained.

Note that the pitch of the tooth type flat blade cutter 30 is set to be equal to or less than the maximum diameter that does not block the collection path.

In addition, the tooth-shaped water-impervious plate 35 provided on the removal-side fixed hood in the removal / recovery mouse has a drum width as its width, and a tooth-shaped flat blade cutter with a divided length is formed at a pitch corresponding to the drum width. By being selected to be fitted at the same time, it is possible to prevent extra water from being sucked from the outside of the removal / recovery mouse 15 and improve recovery efficiency. In addition, the removed deposits are prevented from sticking to the tooth-shaped flat blade cutter 30 and scattering outside the removal / recovery mouse 15.

Further, although the direction of removal of the removal / recovery mouse 15 is directional, the removal / recovery mouse is moved 180 ° each time the rotation angle of the suction pipe 10 changes from 0 ° to + 360 ° or 0 ° to −360 °. Remove / recovery mouse by reversing by rotating mechanism
Since 15 can always be maintained in the removal progress direction, removal / recovery efficiency can be improved.

Also, each time the suction pipe rotates, the length of the axis connecting the rotation center 42 and the removal / recovery mouse 15 at the tip changes every moment,
To remove and collect the culvert surface deposit 41, it is necessary to press the removal and collection mouse against the surface to be cleaned with a certain pressing force or more.
For this reason, the length of the axis of the collection arm 10 is detected by detecting the rotation angle, and the telescopic hydraulic cylinder is numerically controlled so that a predetermined or more pressing force is generated at a predetermined position. Alternatively, an accumulator mechanism may be inserted into the telescopic hydraulic cylinder 16 so that the removal / recovery mouse is always brought into contact with the surface to be cleaned with a predetermined or more pressing force.

As described above, the suction-type cleaning work vehicle of this embodiment has the following effects.

(1) The direction of removal / recovery mouse removal is directional, but the removal / recovery mouse is rotated 180 ° every time the rotation angle of the suction pipe changes from 0 ° to + 360 ° or 0 ° to −360 °. The removal / recovery mouse can always be maintained in the removal progress direction by being reversed by the reversing mechanism to be moved, so that the removal / recovery efficiency can be improved.

(2) Since there is no need to vertically control the removal / recovery mouse on the surface to be cleaned, the removal / recovery mouse and the suction pipe can be connected in a straight line, so that the fluid drag received by high-speed flowing water can be extremely small. Thus, the stability of the suction-type cleaning work vehicle can be greatly improved.

(3) Since the removing device continuously contacts the cross section inside the culvert, there is no cleaning residue.

(4) When a mechanism is installed to collect the removed deposits without dissipating them, there is no marine pollution due to dissipation, cleaning can be performed without affecting the power plant, and the removed deposits are crushed and transported. Therefore, the collection path is not blocked. For this reason, the cleaning operation can be performed without interruption due to a blockage accident.

(5) According to the above (1) to (4), it is possible to provide a highly reliable suction-type cleaning work vehicle that removes and recovers deposits on the intake / drainage channel of the power plant.

〔The invention's effect〕

As described above, according to the suction-type cleaning work vehicle of the present invention, the following effects and advantages can be obtained.

(1) Since a rotating mechanism for reversing a mouse having a directionality efficient for cutting removal and collection at a desired position is provided, a meandering cleaning operation can be continuously performed along a wall surface.

(2) The circuit members between the vehicle body and the actuators and measuring instruments provided on the protrusion of the suction pipe can be connected without using a special entanglement prevention device.
