FIG. 1 shows the structural composition of the main parts of an example of the boiler tube centering device according to the present invention.
is its plan sectional view, b is its front view, Fig. 2 shows the structural composition around the traverse rail that moves the traverse device, a is its plan view, b is its front view, and Fig.
The figure is a control block diagram showing an example of the control method and device according to the present invention. Figure 4 schematically shows the movement of the traverse device to the tube to be inspected (in use), and a shows the tube of the whisker type limit sensor. A state diagram in which the traversing speed switches from high speed to low speed due to contact with the overcurrent sensor, b is a state diagram showing the position La where the output voltage of the overcurrent sensor is below a certain value, and c is a state diagram showing the position Lb where the output voltage is above the certain value. d is a state diagram showing the traversing device returned to the intermediate position between positions La and Lb in figures b and c, FIG. 5 is a diagram showing changes in output voltage at each traversing position, and FIG. It is a figure which shows the change of the output voltage in each traverse position of the conventional boiler tube centering device. DESCRIPTION OF SYMBOLS 1...tube, 2...fixed ash, 3...transverse device, 4...whisker type limit switch, 6...guide plate, 7...non-contact type sensor (eddy current sensor).

とするボイラチユーブセンタリング装置。 A centering device that positions an ash removal tool for removing ash stuck to a boiler tube such as a hanging type boiler tube, and an inspection tool for measuring the outer diameter and wall thickness of the tube at the center of the boiler tube, A traverse device that can continuously move perpendicular to the long axis of the tube so as to sense the center of the tube while covered with the fixed ash is used. A whisker-type limit switch is provided to count the number of tubes and to control the traverse speed at a designated tube position, and is installed in the guide plate that is attached to the traversal device and maintains a constant gap with the tube to allow the fixed ash to pass through. A boiler tube centering device characterized in that it is equipped with a non-contact sensor that detects changes in the magnetic field of the tube itself.
