Description

  The present invention relates to an apparatus for removing deposits in a pipe for removing rust, sludge, dirt, clogging and the like generated in a pipe such as a water supply / drainage pipe.

  Pipes such as drainage pipes and water supply pipes, if rust, sludge, clogs, etc. are generated in the pipes, the flow of water deteriorates due to insufficient pipe inner diameter, and red rust water is also generated. The kimono must be removed.

Conventionally, as a device for removing deposits in a pipe, a rotating member is rotatably provided on a shaft member inserted into the pipe, and the rotating member is rotated by an air motor driven by an air flow flowing in the shaft member. While moving in the direction, the arm member provided on the rotating member is configured to scrape off deposits on the inner surface of the pipe (see, for example, Patent Document 1).
JP 2004-74052 A

  By the way, the deposit removing device in the pipe as described above requires a shaft member having a length corresponding to the whole length in the pipe in order to clean the whole length in the pipe, and is used by connecting a short shaft member. In addition to being bulky, it is inconvenient to transport, and connecting a short shaft member at the site is troublesome and increases the cost of the apparatus and construction.

  In addition, when an air motor serving as a rotational drive source is incorporated in the rotating member, the outer diameter of the rotating member and the arm member attached to the rotating member inevitably increases, and there is a problem in that the attached matter cannot be removed from the pipe having a small inner diameter.

  Furthermore, since the shaft member is not bendable, there is a problem in that it is impossible to remove the deposits on the bent pipe.

  Therefore, the problem of the present invention is that the whole is low in volume and convenient for transportation, the length according to the piping can be easily adjusted on site, and not only can the cost of the apparatus and the construction be reduced, but also the inner diameter is small. It is an object of the present invention to provide an apparatus for removing deposits in a pipe that can remove deposits from pipes to large pipes and that can also handle bent pipes.

  In order to solve the above-described problems, the present invention uses a chain chain as a rotation transmission member, and attaches a deposit removing member to the front end side of the chain chain that connects the rear end to a rotary driving machine. The structure is such that the member rotates integrally with the chain chain and is movable in the radial direction with respect to the chain chain by the centrifugal force during rotation.

  A structure in which the chain chain is covered with a flexible tube such as a synthetic resin can be employed.

  Here, the chain chain can be obtained in a free length by connecting with a pendant chain in the middle.

  According to this invention, the chain transmission chain is used as the rotation transmission member, and the deposit removing member is rotated integrally with the chain chain on the front end side of the chain chain connected to the rotation driving device. Since it is mounted so as to be movable in the radial direction, the chain chain can be used to easily adjust the length according to the piping on site, and the bendability makes the entire unit low in volume and convenient for transportation. In addition, the construction cost can be reduced.

  In addition, the part to be inserted into the pipe is only to attach a deposit removing member such as a grindstone to the tip side of the chain chain, so the diameter can be set freely, and the deposit can be removed from a pipe with a small inner diameter to a large pipe. You can do it.

  Furthermore, since chain chain is used for the rotation transmission member, it is excellent in bendability and can cope with removal of deposits on a bent pipe.

  Further, by covering the chain chain with a flexible tube, the shape retention of the straight line is improved while maintaining the bendability of the chain chain, and the insertion into the tube can be performed smoothly.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the apparatus for removing deposits 1 in a pipe uses a chain chain 2 as a rotation transmission member, and connects the chain chain 2 connected to a motor 3 serving as a rotary drive device whose rear end is arranged outside the pipe A. The deposit removing member 4 is attached to the front end side, and the deposit removing member 4 rotates integrally with the chain chain 2 and is movable in the radial direction with respect to the chain chain 2 by a centrifugal force at the time of rotation.

  In the case of the figure, the chain chain 2 is formed to have a predetermined length by sequentially connecting a number of chain units 2 a having ring sections 6 at both ends of the shaft section 5 by the ring sections 6. Bending can be performed at the length position of the single body 2a, and rotation can be transmitted by the engagement of the ring portion 6. By selecting the number of connected chain single bodies 2a, the length can be set freely.

  The motor 3 for connecting the rear end of the chain chain 2 is arranged at the end of the pipe A so as to be movable in the length direction of the pipe A, and uses a small electric motor whose rotation speed can be adjusted. The rear end side of the chain chain 2 is clamped by the chuck 7 provided to the chain chain 2 so that the chain chain 2 is rotated about the axial center in the length direction.

  The chain unit 2b located at the forefront of the chain chain 2 has no ring part 6 at the tip of the shaft part 5, and the shaft part 5 becomes a square axis or a flat axis, and the deposit removing member 4 is used for the most advanced chain. It is attached to the shaft portion 5 of the single body 2b.

  As shown in FIG. 2, the deposit removing member 4 uses a disk-shaped grindstone 4 a, and a radial long hole 8 passing through the shaft center is fitted into the shaft portion 5, so that the rotation direction of the long hole 8 and the shaft portion 5 is Is rotated integrally with the chain chain 2 and is movable in the radial direction with respect to the chain chain 2 by a centrifugal force generated during the rotation.

  In the case of illustration, the two grindstones 4 a are fitted and inserted into the shaft portion 5, and the two grindstones 4 a can be moved in the radial direction by the spacing piece 9, the receiving plate 10 and the retaining nut 11 attached to the shaft portion 5. It is attached to the axial part 5 so that it may become.

  As shown in FIG. 2C, the grindstone 4a reinforces the periphery of the long hole 8 with a metal plate 12, and prevents the long hole 8 engaged with the shaft portion 5 in the rotation direction from being damaged. However, the deposit removing member 4 is not limited to such a grindstone 4a, and a disc-shaped wire brush, brush, or the like can be employed.

  In order to adjust the chain chain 2 to a length corresponding to the pipe A, a pendant chain unit 2c as shown in FIG. 3B is used, and the pendant chain unit 2c is used at appropriate intervals. Thus, the length of chain chain 2 is variable.

  The pendant type chain 2c has a ring-shaped part 6 cut off, and has a carabiner-like structure in which the opening / closing operation shaft 13 that opens and closes the cut-off part is urged by elasticity in a direction to always close the cut-off part. Thus, the structure is such that the chiene simple substance 2c is not detached.

  Further, as shown in FIG. 3A, the chain chain 2 is covered with a flexible tube 14 such as a synthetic resin or rubber over the entire length or a required portion, thereby maintaining the bendability of the chain chain 2 in a straight line. It is possible to improve the shape-retaining property and smoothly perform the insertion work into the pipe A.

  The deposit removal apparatus of the present invention has the above-described configuration. Next, a deposit removal method using this apparatus will be described.

  In order to remove rust, sludge, clogging, etc. generated in the pipe A such as the water supply / drainage pipe, a chain chain 2 having a predetermined length is prepared, and 70-80% of the inner diameter of the pipe is provided at the tip side of the chain chain 2. A grindstone 4a having a certain diameter is attached, the rear end side of the chain chain 2 is clamped by the chuck 7 of the motor 3, and the front end side to which the grindstone 4a of the chain chain 2 is attached is inserted into the pipe A from one end. .

  With the grindstone 4a positioned in the pipe A, when the motor 3 is activated and the chain chain 2 is rotated around the longitudinal axis, the grindstone 4a attached to the chain chain 2 is rotated. The grindstone 4a moves in the radial direction by the centrifugal force generated by the rotation, so that the outer peripheral surface comes into contact with the inner peripheral surface of the pipe A, and this abutting portion is formed by the rotation of the grindstone 4a and the turning by the eccentricity. By shifting with respect to the entire circumference of the inner peripheral surface, the inner peripheral surface of the pipe A will be shaved, thereby removing rust, sludge, clogging, etc. occurring in the pipe A, In this state, when the chain 3 is moved into the pipe A by moving the motor 3 toward the pipe A, the contact portion of the grindstone 4a with the inner peripheral surface of the pipe A is in the axial direction of the pipe A. Transition.

  In this way, rust, sludge, dirt, clogging, and the like generated on the inner peripheral surface of the pipe A can be removed by adding rotation and axial movement due to rotation and eccentricity to the grindstone 4a.

  When the chain chain 2 is inserted into the pipe A for a predetermined length, the rotation of the motor 3 is stopped, the chain chain 2 is added using the pendant chain unit 2c, the motor 3 is started again, and the grindstone 4a is attached. By adding rotation and axial movement due to rotation and eccentricity, and repeating the chain chain 2 as described above as many times as necessary, rust, sludge, clogging, etc. can be removed over the entire length of pipe A. become.

  In addition, the deposit removing member 4 at the tip of the chain chain 2 is changed to a wire brush or brush in addition to the grindstone 4a in accordance with the properties of rust, sludge, dirt, clogging, etc. generated on the inner peripheral surface of the pipe A. In addition, by using the pendant type chain unit 2c at regular intervals, the length of the chain chain 2 inserted into the pipe A can be grasped, and the chain chain 2 is Because of the bendability, the deposits can be removed even on the curved pipe A.

  When the removal of rust, sludge, clogging, etc. over the entire length of pipe A is completed, the chain chain 2 is extracted from the inside of pipe A, and then the inside of pipe A is cleaned. The pipe A is completely regenerated by forming a lining layer of vinyl by applying a rust preventive treatment using

  Such rust prevention treatment and lining layer formation can be carried out by using the chain chain 2 described above and attaching an application member to the tip thereof.
