Description

The paint injection apparatus of inside pipe wall}

The present invention relates to a paint spraying device for the inner wall of the pipe, and more particularly, a spray nozzle mounted on the spraying device that is movable inside the pipe is used to paint the inner wall of the pipe with an optimal thickness while maintaining a proper distance from the inner wall of the pipe. It relates to an injection device. In addition, the present invention relates to a paint spraying apparatus capable of painting paint after washing the inner wall of the pipe even after long time use.

In general, the inner wall of a metal pipe may be corroded when fluid such as water flows. Also, in the case of a pipe or a pipe joint or a flange joint, a flange and a pipe joint are made of welding, so corrosion is particularly evident in the welding area. This is likely to occur. Therefore, it is necessary to paint the inner wall of the pipe used to prevent corrosion of the inner wall of the pipe and to prolong the service life of the pipe. In addition, when the water pipe or sewage pipe is aged as the underground pipe, the pipe itself cannot be lifted to the ground, so it must be possible to spray paint while driving in the underground pipe.

Looking at the prior art, Japanese Patent Laid-Open No. 58-43265 discloses an invention of a technique for detecting and painting a portion of an unpainted portion of a welded portion. The above description discloses a technology in which the meter reading operation is performed to paint the uncoated portion at the operation panel when the meter reading portion is uncoated. However, the above technique has a problem in that it is difficult to use in the case of underground pipes, since the pipe and the pipe to find and paint only the part connected by welding.

As another conventional technique, Japanese Patent Application Laid-Open No. 61-293571 describes a coating apparatus in which a coating material and a coating material curing agent are mixed and sprayed by an air motor. Since the coating device does not have its own power, it is difficult to form a coating film of a certain thickness because it must be pulled artificially. In addition, since it is injected through the injection hole or the injection slit, it is difficult to form a certain coating film when a part is blocked, and a problem in the coating film formation may occur even when the device is shaken due to the vibration of the motor. In addition, there is a problem that may not always be in a constant position inside the tube because there is no appropriate footing to prevent the vibration of the motor.

As a domestic prior art, there is a patent 391389. Patent No. 391389 also describes a device capable of painting a steel pipe and a portion to which the pipe is connected, and describes a device for finding and painting an unpainted portion, such as Japanese Patent Application Laid-Open No. 58-43265. . Therefore, Patent No. 391389 also has the same problem as the Japanese Patent Laid-Open No. 58-43265. In addition, since the scaffold is formed only at the lower end, the apparatus may not have a predetermined position in the tube, or may fall sideways in the tube if the apparatus does not have a constant position. In addition, there is a problem that it is difficult to elastically support the vibration of the motor. In addition, in the case of underground pipes, or when washing and painting the interior after using a long time may be a constant inside the pipe, there may be a problem that the device is unstable and difficult to apply uniformly. In addition, there may be a problem that it may take a long time to apply the entire inside of the tube.

The injection body is connected to the rotary shaft and receives paint from the rotary shaft. The supplied paint is collected in the hollow, and when the valve is opened, it is supplied to the spray nozzle through the spray pipe, and sprayed on the inner wall of the pipe through the spray nozzle.

The injection pipe is configured such that the side on which the injection nozzle is mounted is farther from the central axis X of the rotating shaft than the side on which the on / off valve is mounted. The mounting hole for mounting the nipple is composed of two to four. Nipple means short pipe. The nipple may be supplied connected directly to the valve. In this case, the valve can be mounted directly to the mounting hole. The spray nozzle is configured to be remote from the central axis to maintain the optimum distance of 30 cm from the inner wall of the pipe. It is preferable that the lengths of the injection pipes are different from each other so that the heights of the injection nozzles connected to the injection pipes are different from each other. Since the injector can be painted twice and four times as the apparatus advances, the length of the injector is preferably different. The direction of the jet nozzle is mounted to face the central axis (X). By facing the central axis (X), the spray nozzle can maintain the optimum distance to the inner wall of the pipe. The optimum distance can be sprayed in the form of agglomeration when the injection nozzle is too close to the inner wall of the tube, so that the coating thickness may not be constant, and the coating area is also narrowed, which may hinder rapid operation. Therefore, the injection nozzle is preferably configured to be far from the inner wall to be painted so as to maintain the optimum distance to the inner wall of the pipe.

The operating principle of the preferred embodiment of the present invention will be described. The plurality of motors 111 of the paint injector 1 rotate first. When the motor 111 rotates, the motor chain gear 113 also rotates together, and the motor chain gear 113 is connected to the chain gear 12a of the second driving connector 12. When the second drive connector 12 is rotated, the rotating shaft 10 rotates together. In addition, the first drive connector 11 also rotates together with the rotation shaft 10, and the chain gear 11a of the first drive connector 11 also rotates together. The rotation of the chain gear 11a also rotates the chain gear 206 mounted on the pinion shaft 205 together. The pinion shaft 205 is rotated by the rotation of the chain gear 206, the rotation of the pinion shaft 205 rotates the pinion 204, and the bevel gear 203 of the wheel is rotated by the rotation of the pinion 204. The wheel 202a is driven back and forth. The direction of rotation is switched by the bevel gear 203, so that the rotation of the motor 111 enables front and rear driving of the wheel 202a. At the same time as the wheel rotates, paint is supplied through the paint supply hose 15 to the rotating shaft 10 of the hollow cylinder. When the paint is supplied, the paint supply hose 15 is fixed but the rotating shaft 10 is rotated, so the swivel 14 is required. Due to the mounting of the swivel 14, the rotating shaft 10 can be freely rotated, it is possible to prevent the twisting of the paint supply hose (15). The paint passing through the rotating shaft 10 is collected in the hollow 308 of the injection unit body 301, and the collected paint is injected into the injection nozzle 307 through the injection pipe 306 at a constant pressure. The spray nozzle 307 is sprayed toward the center at different heights, and is formed so that the spray nozzle can spray at an optimum distance from the inner wall of the pipe.
