Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe cleaning machine suitable for removing and cleaning marine life adhering to the inner surface of a cooling seawater pipe of a power plant.

[0002]

[Prior art]

 Conventionally, as a cleaning machine for cooling seawater pipes, as shown in the side view of FIG. 4, a moving carriage 32 is carried into the inner surface of the pipe 31, a ceiling wheel 34 is pressed by a cylinder 33 and a posture is held, and a manipulator 35 is rotated. However, there is one that ejects a high-pressure jet water nozzle 36 attached to the tip thereof. However, the conventional machine requires a large number of actuators for driving and manipulating the wheels of the mobile trolley and the manipulator, and because of friction drive, the structure is complicated and large to obtain a large traction force. In addition to difficult problems, there are drawbacks that equipment and maintenance costs are high. In addition, stability may be impaired at high flow rates.

[0003]

[Problems to be solved by the device]

 The present invention has been proposed in view of such circumstances, and it provides stable driving performance without requiring a powerful motor for driving, and ensures speed adjustment and stop position determination accuracy, and It is an object of the present invention to provide a pipe cleaning machine with a simple structure that can perform good cleaning with inexpensive equipment.

[0004]

[Means for Solving the Problems]

 To this end, the present invention comprises a cylindrical front carriage and a cylindrical rear carriage that are pin-coupled to each other, a front and rear slide and a motor mounted on the front carriage, and a radial attachment to the output shaft of the motor. Cylinder, a cleaning brush attached to the tip of the cylinder, a nozzle attached to the rear end of the rear carriage and a motor-driven thruster installed inside the nozzle, and fixed to the front of the rear carriage. A cylinder, a link mounted on the tip of the cylinder in a radially openable and closable manner, and a brake shoe mounted on the outer end of the link.

[0005]

[Action]

 In the pipe cleaning machine of the present invention, the front and rear bogies move forward and backward in the pipe by the forward and reverse rotation of the thruster of the rear bogie, and the contraction of the cylinder of the rear bogie spreads the link toward the inner wall of the pipe and brakes. The forward and reverse speeds can be adjusted and stopped to prevent the water from flowing. Then, while driving, the cleaning brush is rotated while being pressed against the inner wall of the pipe by the motor of the front carriage to remove and clean the sea life. If necessary, especially at a large amount of the adhered area, the brake is strongly actuated to stop the front carriage and the rear carriage, and while rotating the cleaning brush, the cleaning brush is finely fed in the axial direction of the pipe by sliding. Meticulous operation. Furthermore, since this cleaner is divided into a front bogie and a rear bogie, and is connected by pins, it can be applied to horizontal curved pipes such as elbows.

[0006]

【Example】

 An embodiment of the cleaning device for a pipe according to the present invention will be described with reference to FIG. 1, a side view, and FIG. 2 and FIG. 3 which are cross-sectional views. It is divided into a cylindrical rear trolley 3 and both are connected to each other by a pin 4. Legs 5 are projected downward in the front bogie 2 in a figure-eight shape, and driven wheels 6 are attached to the front bogie 2. A cylinder 7 is fixed to the rear end side at the inner center of the front bogie 2. The movable rod at the other end is connected to the sliding slides 9 having the shafts 8 extending from the front end to the rear end as guides on both sides thereof. A motor 10 is fixed to the front surface of the slide 9, spokes 11 are radially attached to the output shaft of the slide 9, cylinders 12 are attached to the other ends of the spokes 11, and a cleaning brush is attached to the rods. The seal 13 is attached.

On the other hand, the rear carriage 3 is provided with legs 14 projecting downward in an eight-shape, and driven wheels 15 are attached to the rear carriage 3, and at the rear portion of the rear carriage 3, there is a trumpet-shaped nozzle with a stay 16. A thruster 19 is set on the output shaft of a motor 18 fixed to the rear of the center of the nozzle 17 so as to project in the center of the nozzle 17. Further, a cylinder 20 is fixed to the center front part of the rear carriage 3, a link 21 is attached to its movable rod outside three directions, and its tip is attached to the outside of the rear carriage 3 by pin connection. The link 22 is pin-coupled to the middle part of the link 22, and a parallel link is formed between this link 22 and a link 23 located behind it and pin-coupled to the rear carriage 3. The brake shoe 24 is pin-connected to the end.

In such a cleaning machine, the front carriage 2 and the rear carriage 3 are moved forward and backward in the pipe 1 by the forward and reverse rotation of the thruster 19 of the rear carriage 3, and the link 22 is caused by the contraction of the cylinder 20 of the rear carriage 3. , 23 spread toward the inner wall of the pipe 1 and actuate the brake shoes 24, thereby enabling the front and rear trolleys 2 and 3 to be adjusted in forward and backward speeds and stopped so as not to be swept by the water flow. Then, during traveling, the cleaning brush 13 is rotated while being pressed along the inner wall of the pipe 1 by the motor 10 of the front carriage 2 to remove and clean the sea life. If necessary, the brake shoe 24 is strongly operated to stop the front carriage 2 and the rear carriage 3 at a particularly large amount of the adhered portion, and the cleaning brush 13 is rotated by the slide 9 while the cleaning brush 13 is rotated. Perform fine operation by feeding a fine pitch in the direction. Further, since the cleaning machine is connected to the front carriage 2 and the rear carriage 3 by the shunting pin 4, it can be applied to a horizontally curved pipe such as an elbow.

Therefore, according to this cleaning machine, the thruster 19 of the rear carriage 3 moves forward and backward, and does not require a powerful motor because it is not the conventional friction drive system, and the traveling ability is deteriorated due to the high flow velocity. Since there are relatively few, there is no indeterminate trouble such as slippage due to sludge sticking to the wall surface of the pipe 1, so stable running performance is obtained, and the speed is adjusted by thrusting the brake shoes 24 toward the inner wall of the pipe 1 in three directions. ， The positioning accuracy of stop is reliable, and the simple configuration enables good cleaning with inexpensive equipment.

[0010]
