[Industrial Application Field] The present invention measures the cross-sectional shape of a high-temperature rod-shaped (including tubular) object in a non-contact manner. In particular, the present invention relates to a cross-sectional shape measuring device that can continuously measure the cross-sectional shape of an object even when the object is continuously moving. [Prior Art] Japanese Patent Application Laid-open No. 59-27210 and Japanese Patent Application Laid-Open No. 1983-1982 are devices for non-contact measurement of the cross-sectional shape of a high-temperature rod-shaped object that is continuously moving. There is one disclosed in Publication No. 58-131503. The former measurement device is designed to measure the cross-sectional shape of a hot-rolled section steel, and it holds a cylinder so that it rotates surrounding the section steel, and points it toward the center of rotation of the cylinder. It has a configuration in which one non-contact distance meter is attached to a cylindrical body. When measuring, the device is installed in the line before casting and rolling, and once the shaped steel flows onto the rollers, the cylinder is rotated 360° and a non-contact distance meter is used to sequentially measure the length of the shaped steel to the measuring point. The distance is measured, and each measured position (rotation angle of the cylinder) is detected by an angle detector. The measured and detected data are input to a computing device. The computing device is programmed to calculate the cross-sectional shape and dimensions of the section steel based on these data. The latter measurement device is designed to measure the cross-sectional shape of billets and has almost the same configuration as the former measurement device, but a reflector was attached to the tip in order to calibrate errors caused by thermal strain. It incorporates a calibration cylinder. A pair of non-contact distance meters are mounted facing each other on the cylinder. The latter measurement device is not much different from the former measurement method, but the difference is that before measurement, a reflector is used to collect data before thermal strain and is used to calibrate thermal strain errors. [Problem that the invention aims to solve] Precision measuring devices such as laser distance meters are often used as non-contact distance meters, but such measuring devices are generally designed to be used at room temperature. There is. When the temperature of the measurement area is high and you try to measure over a long period of time, the temperature of the laser rangefinder itself increases due to radiant heat, which not only causes measurement errors but also damages the light receiving element, which is the lifeblood of the measuring device. or may destroy the ICs that make up the electronic circuit. Especially when measuring the cross-sectional shape of hot-rolled sections or continuous casting billets,
The measuring device is exposed to harsh temperature conditions. However, conventional measuring devices do not have any heat protection measures, making continuous measurement impossible. To enable this continuous measurement, it is necessary to prevent the temperature of the non-contact distance meter from exceeding 50°C. Possible countermeasures for this include using insulation materials and blowing cooling air. However, with these measures,
Continuous measurements were not possible due to the dimensional limitations of the equipment or because it was too close to the hot mass. Therefore, an object of the present invention is to provide an apparatus for measuring the cross-sectional shape of a high-temperature rod-shaped object, which overcomes the above-mentioned problems by other means. [Means for solving the problem] In order to achieve the above object, the present invention has a non-contact distance meter arranged on a disk that rotates or oscillates around a hot rod-shaped object to be measured, facing the center of rotation of the disk. The apparatus for measuring the cross-sectional shape of a hot rod-shaped object is characterized in that a water-cooled jacket is interposed between the hot rod-shaped object and a non-contact distance meter, and a distance measurement window is provided in the water-cooled jacket. Although a water cooling jacket alone is sufficient to protect a non-contact distance meter from radiant heat, the effect will be even greater if a heat shielding device is further provided in the distance measurement window or the measurement hole of the non-contact distance meter. As the heat shield device, a shutter that opens in conjunction with measurement or a filter that reflects infrared rays can be used. [Function] During measurement, by flowing water through the water cooling jacket, it not only directly blocks the radiant heat from the hot bar-shaped object to be measured, but also lowers the air temperature near the non-contact range meter, so the temperature of the non-contact range meter decreases. can be kept below the breakdown temperature, making continuous measurement possible. Furthermore, when the water cooling jacket is directly attached to the disk, the disk is also cooled, so that thermal distortion of the disk can be suppressed to a level that is virtually non-problematic. [Embodiments] Hereinafter, embodiments of the present invention will be described with reference to the drawings. A specific example of the device is schematically shown in FIGS. 1 to 3. This device measures the cross-sectional shape of a round CC hot billet, and as shown in FIG.
It consists of Mobile device 1 in this case
0 is a mechanism 11 for raising/lowering/traversing the detection unit 20;
It is equipped with 12. The elevating mechanism 11 includes a detection unit 20
This is for taking the sample into and out of the measurement line A, and is installed in the traversing mechanism 12. Traverse mechanism 12
The detection unit 20 is connected to the measurement line A and the non-measurement line B.
It is designed to move along an outer frame 13 that is assembled into a frame. For both mechanisms 11 and 12, known means such as linear movement mechanisms such as an actuator or a rack and pinion can be employed. By the way, in the measurement line A, there is a conveyor roller 2 in the running direction of the hot billet (high-temperature rod-shaped object) 1.
are listed in large numbers. And the aforementioned detection section 20
is moved in and out between the conveyance rollers 2 by the moving device 10. The detailed configuration of the detection unit 20 is shown in FIGS. A disk 22 is rotatably or swingably incorporated into the detection frame 21. The disk 22 is arranged on the detection frame 21 so that its plane 22a is perpendicular to the axial direction of the hot billet 1 on the measurement line A. A hole 22b is provided in the center of the plane 22a to allow the hot billet 1 to travel. The lower part of the disk 22 is cut out until it reaches the hole 22b described above so that the disk 22 can be taken in and out of the measurement line A even while the hot billet 1 is running. The width of the notch 22c is made larger than the diameter of the hot billet 1. Three or more non-contact distance meters 23a, 23b, 23c, 23d are installed on the flat surface 22a of the disk 22.
The circumferences of 2 are fixed evenly or approximately equally distributed. When considering the number of non-contact distance meters 23a,..., evaluations were obtained as shown in Table 1 below.

As explained above, according to the present invention, the radiant heat received from the hot bar-shaped object to be measured can be significantly reduced, so that cross-sectional shape measurements in hot lines can be continuously performed.
