Description

The removal device of fixed substance inside wall of pipe}

The present invention relates to a device for removing rust, scale, etc. that is fixed in the pipelines such as pipes, and more specifically, to drive the fixed material removal unit of the rotating body by the rotational force of the motor, the fixed material removal unit is driven A plurality of cleaning units mounted on the apparatus is to scrape the adhered to the tube while rotating the inside of the tube to remove the stuck material.

In general, when a metal tube flows into a tube, the fluid reacts with the tube, and rust or scale accumulates on the inner wall of the tube, causing foreign substances to be fixed. Secured materials not only cause corrosion inside the tube, but also impede the flow of the fluid, thus locally blocking the flow of the fluid, which can lead to high pressures which can cause the flange or pipe of the seam to rupture.

Thus, there is a need for means to remove material stuck inside the tube. Foreign substances stuck inside the pipe through a long time can not be easily removed by the usual means, a means to give a strong impact is needed. Otherwise, the only way to fix rust or scale is to cut off a large portion and connect a new tube. However, a metal tube or the like is expensive, or if it is buried in the ground, labor costs will be increased. Therefore, it is economically undesirable to simply cut out the tube to which the scale and the like are fixed and weld it with a new tube.

Also, cutting out parts and connecting new tubes is not an easy process. The reason is that the newly connected pipe does not have scale such as rust, but the existing pipe will be scaled, so welding is not easy.

In addition, in the case of a pipe made of concrete or the like, it is not economically desirable to remove the portion where the scale is fixed and replace it with another one.

In general, as a method for removing a stuck substance stuck in an aging pipe, a device for removing a fixed substance inside a pipe by using a stuck substance removing device equipped with a motor has been used. Patent 654986 proposes a dry matter removing apparatus using such a motor.

Since the equipment according to Patent No. 654986 uses a foreign material removing means such as a chain connected radially to the rotating body, the area contacted by the chain is considerably narrow, and it takes a considerable time to remove the fixed matter, and part of the fixing material There was a problem that parts that can not be removed.

In addition, since it is made of dry, dust may enter the inside of the machine and cause a breakdown, and only the wheel on one side may move elastically according to the height of the inner wall of the tube. Due to the vibration caused by the imbalance there was a problem that the fixing may not be properly removed.

In addition, there is a problem that it is difficult to remove the fixed material that does not easily fall by the attraction even after the impact on the inner wall of the tube with the device.

The present invention is to solve the above problems, the object of the present invention is to provide a device that can be carried out by an efficient operation by widening the area for removing the fixed matter.

It is also an object of the present invention to provide a device capable of removing dust in a tube in a wet manner and in a balanced way of removing deposits in spite of vibration caused by the rotation of the motor or unbalance of the inner wall of the tube.

It is also an object of the present invention to provide a device capable of effectively removing the fixed matters by spraying the inner wall with high pressure water, first removing some fixed matters with the high pressure water, and subsequently removing the foreign matters.

In addition, an object of the present invention is to provide a device that can increase the work efficiency by processing in a large area of the inner wall of the pipe in a short time.

An object of the present invention as described above, in the apparatus for removing the fixed matter inside the pipeline, the motor body having a rotating shaft and a rotating shaft frame formed on the outside of the rotating shaft shorter than the rotating shaft; A first scaffold positioned on one side of the motor body and mounted to the rotation shaft frame of the motor rotation shaft; Located on one side of the first scaffold, the fixture removal unit mounted to the rotating shaft of the motor; A flange portion formed on the other side of the motor body; A water spray unit formed in the flange portion; A high pressure water connecting tube formed on the other side of the flange portion so as to communicate with the water spraying portion; A second scaffold mounted on the high pressure water connector; And a high pressure water supply hose connected to the high pressure water connection pipe.

The first scaffold and the second scaffold include a scaffold frame having shaft holes formed therein, a plurality of fastening portions formed by a pair of protruding pieces formed on the outer circumferential surface of the scaffold frame, and a supporting member inserted into and fixed to the fastening portion. It is preferable that the scaffold frame has a circular or square shape, and a pair of protruding pieces are formed on the outer circumferential surface to serve as a fixing part. That is, the supporting member is configured to be inserted into the fixing portion and fixed. The supporting member refers to the part directly contacting the inner wall of the pipe. Since a plurality of support members are in contact with the inner wall of the tube can be stable even when the motor is driven. In addition, the supporting member may be configured such that the removal device of the present invention can be easily moved forward by forming a taper on one side of the frame of the square pillar to contact the inner wall of the tube. If the support member is in excessive contact with the inner wall of the tube, the friction force is increased, so that it is difficult to move, so it is preferable that the supporting member portion in contact with the inner wall of the tube does not have a large area.

In the supporting member of the first and second scaffolding, through holes are formed in the pair of protruding pieces and the supporting member, and the fixed shaft is inserted through the through holes formed in the protruding piece and the supporting member, and the fixed shaft is formed in the scaffold frame. It is supported and mounted by. Since the supporting member should be configured to be inserted into and fixed to the protruding piece, it forms a through hole in the protruding piece and the supporting member, and is configured to fix the supporting member by inserting a fixed shaft. The fixed shaft is again supported by the support.

The through-holes formed in the protruding pieces of the first and second scaffolds have a spaced distance of a predetermined distance so that the fixed shaft can move up and down.

Since the supporting member can move by a predetermined distance along the space, it can be used elastically according to the inner diameter of the pipe.

The fixed shaft inserted through the through-holes formed in the protruding piece and the supporting member may have a circular, rectangular, hexagonal or elliptical shape with a cross-sectional shape. In the case of a circular shape, since it can move freely in a certain range with respect to the axis, it can move fluidly even when the height inside the pipe is different. In addition, when the fixed shaft is inserted to be fixed so that the support member does not move, the cross-sectional shape of the fixed shaft may be used to angle or form a plane.

The support part for supporting the fixed shaft is composed of a screw part composed of a bolt and a nut mounted on the scaffold frame and an elastic member inserted into the screw part. The bolt is inserted into the through holes formed at both ends of the fixed shaft and fixedly mounted on the scaffold frame to support the fixed shaft. The elastic member is inserted between the bolt and the fixed shaft to elastically support the fixed shaft, and the nut is configured to limit the vertical movement of the fixed shaft. The support portion for supporting the fixed shaft is preferably configured to elastically support using bolts and nuts and elastic members. Since the inner wall of the tube is fixed to scale, rust, etc., the diameter of the tube cannot be constant. Therefore, the device moving along the inner wall of the pipe should be able to move elastically to the uneven inner wall of the pipe. Therefore, in the present invention, the elastic member is inserted into the bolt at the lower end of the fixed shaft and configured to be elastically movable according to the inner diameter of the tube.

Since the first cleaning part is a part of the fixing material removal part inserted and fixed to the rotating shaft, the first cleaning part rotates along with the rotating shaft. Since the first cleaning part has a plurality of grooves formed in the rotational direction on the outer circumferential surface of the drum and contacts the inner wall with the rotation of the motor, it is possible to remove the deposits on the inner wall of the drum. In addition, as the grooved drum rotates, severe impact may be applied to the drum when the inner diameter of the tube is not constant. In order to prevent this, the device according to the invention is configured to insert an elastic member in the center so that it can be elastically rotated according to the inner diameter. That is, one side of the H-shaped frame is configured to be fixed to the removal unit frame to rotate a predetermined distance, the other side so that the drum is fixed to the H-shaped frame axially, through the center of the H-shaped frame to form a through hole The H-shaped frame is elastically movable by inserting a spring and a bolt which are elastic members in the ball, and the upper bolt of the H-shaped frame is fitted with a nut to limit the vertical movement and the inner diameter of the H-shaped frame.
