本発明は管内面付着物清掃(除去)装置、特に
管内面に強固に付着している物であつてもこれを
完全に除去しうる装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for cleaning (removing) substances adhered to the inner surface of a tube, and more particularly to an apparatus capable of completely removing substances even if they are firmly attached to the inner surface of the tube.
例えば、水中又は土中に敷設された大径管を所

が必要とされる。 For example, when cutting a large-diameter pipe installed underwater or in the ground to a predetermined size or painting the inside surface, it is necessary to keep the inside surface of the pipe clean. In particular, as a technique for cutting steel pipes that have recently been laid underwater at predetermined positions, a hollow cutting rod that is rotatably held in the circumferential direction is directed at the inner wall of the pipe, and the tip of the cutting rod and the inner wall of the pipe are connected. Devices have been developed and are being put into practice that cut pipes by creating an arc between the pipes and ejecting oxygen from the cutting rod, resulting in an oxidation reaction. In this case, there is soil at the point where the pipe is planned to be cut.
If sand, rust, seaweed, concrete, mortar, etc. (hereinafter simply referred to as deposits) are adhered to the product, a good arc may not be generated during cutting, which may hinder the cutting operation. It is necessary to completely remove deposits from this area in advance.

いた。 Conventionally, there have been cleaning devices that rotate cleaning elements such as wire brushes for the purpose of cleaning the inner surface of pipes, but these devices cannot remove dirt, sand, etc. that are not very firmly attached to the inner surface of the pipe. However, it is impossible to remove firmly adhered materials such as concrete and mortar (hereinafter referred to as hard deposits). Furthermore, conventional cleaning devices cannot cope with changes in pipe diameter, and the cleaning element must be replaced each time with a cleaning element that matches the pipe diameter.

内面清掃装置を提供することにある。 In view of these points, the present invention provides a device for cleaning hard deposits on the inner surface of a pipe, which can reliably remove any deposits and can also follow changes in the pipe diameter without replacing any parts. The purpose is to Another object of the present invention is to provide a pipe inner surface cleaning device that can automatically remove deposits by remote control under any pipe laying conditions, whether underwater or underground.

る。 In the illustrated example, three cleaning blocks 10 are arranged at equal intervals, but in the present invention, any number of cleaning blocks 10 may be installed as long as it is one or more. Further, the clamp mechanism A and various drive mechanisms are not limited to the systems shown in the drawings, and it goes without saying that other known systems may be used as long as they function similarly.

(第1図)。 First, the clamp mechanism A and the removing device main body B are suspended from the upper end of the pipe 1 by a crane at the position of the hanging holder 11 and then inserted into the pipe. In this case, only the guide rollers 2, 2' are in contact with the inner wall surface of the pipe, the clamp heads 3, 3' are retracted, and the cleaning block 10 is folded toward the center of the pipe as shown in the upper right corner of FIG. This facilitates passage into the pipe. When the removal device main body B reaches a predetermined position in the pipe, the suspension movement is stopped and the rotary cylinder 5 is driven to extend the clamp heads 3, 3' in the pipe radial direction to firmly clamp and fix the position ( Figure 1).

る。 Once the positions have been determined, each of the three cleaning blocks is driven by the rotating rotary cylinder 17 to swing the swinging arm 21 in the horizontal direction about the rotating shaft 23 and press it against the pipe wall. Swing arm 21
The rotation of the floating head 2 of the cleaning block
The brush 29 stops when it comes into contact with the pipe wall, and at this position the brush 29 is also pressed against the pipe wall by the spring 26. Assuming that the cleaning work is started from the time when the lifting cylinder 7 is retracted, the jet chisel 30 is operated to extend the lifting cylinder 7 while hitting the pipe wall. The cleaning block moves in the axial direction of the tube, and uses a combination of frictional sliding on the inner surface of the tube wall by the wire brush 29 and impact by the jet chisel 30 to completely remove deposits and clean the tube wall in a band shape with a constant width. Let's do it. When the lifting cylinder 7 reaches a predetermined stroke amount (this becomes the cleaning length in the tube axis direction, this is set in advance using an electrical means such as a timer or switches), the tube axis of the cleaning block The movement in this direction is stopped, and then the cleaning block is moved in the circumferential direction. This movement in the pipe circumferential direction is limited to within the belt-shaped cleaning width described above. This operation of moving the worm 1 in the circumferential direction is performed by driving the rotary cylinder 13 for turning.
5 and the pivot shaft 33 via the worm wheel 16
This is done by rotating. Next, when the elevating cylinder 7 is operated in the retracting direction, the next strip-shaped cleaning is performed while wrapping around the previous cleaning width.

げ、管外に装置全体を取出せばよい。 In this way, by combining the operations of the lifting cylinder 7 and the rotating rotary cylinder 13, cleaning is performed in a rectangular wave pattern, and if one cleaning block moves 120 degrees in the circumferential direction of the pipe, a predetermined area within the pipe 1 can be cleaned. Cleaning of the entire circumference is completed. After cleaning is completed, the swinging arm 21 is retracted toward the center of the tube, the clamp heads 3, 3' are retracted, and the whole apparatus is lifted up with a crane and taken out of the tube.

清掃に適用し得る。 In addition, in the figure, three cleaning blocks each cover 120 degrees, but for other installations, for example, one block can cover 360 degrees.
゜, 180° for 2 pieces, 90° for 4 pieces, etc. Further, although the movement locus of the cleaning block has been shown as an example of a rectangular wave shape, the present invention is not limited to this, and any other arbitrary locus may be used, for example, a method in which cleaning is performed first in the circumferential direction and then shifted in the axial direction one stage at a time, or A method may be adopted in which the lifting cylinder 7 and the rotating rotary cylinder 13 are operated simultaneously to perform cleaning in a spiral manner. Further, if the inside of the pipe is not very firmly adhered, cleaning may be performed only with the wire brush 29 without operating the jet chisel 30. Starting various drive mechanisms,
Stopping and interlocking operations can be performed according to a predetermined program by providing an appropriate control mechanism. Of course, the apparatus of the present invention is not limited to cleaning the inside of a pipe during underwater cutting, but can be applied to cleaning the inside of a pipe in other appropriate conditions.

It is possible to completely remove and clean all the deposits attached to the inner surface of the pipe, which is difficult to remove in the past.
Even strong hard deposits such as mortar can be removed. In addition, cleaning work can be done almost automatically, improving work efficiency. Furthermore, in the present invention, since the swinging fulcrum of the swinging arm to which the cleaning block is attached is located at a position different from the center of the pipe, there are advantages such as the ability to respond to changes in pipe diameter by simply changing the swinging angle. be.
