The center line L of the transfer table 30 of the rolling line is symmetrical with a predetermined position on-line at a predetermined interval and is horizontally fixed at a predetermined height in a direction perpendicular to the line. It is possible to run.

The on-line rail 6 is vertically movable between the off-line rails 7 and 8, and when it is at the same height position as the on-rails 7 and 8, the on-line rail 6 is substantially linear with the on-rails 7 and 8. And the C-shaped trolleys 10 and 20 can run.

The lifting device EL includes a screw jack 1
a, 1b, a rotary drive motor for giving a rotational drive force, and the power of the vertical drive motor 3 is transferred to the screw jacks 1a, 1b.
1b, and a guide 5a, 5b for guiding the elevating table 4 on which the online rail 6 is fixed. The online rail 6 is moved up and down. When measuring the dimension of the material, for example, the H-section steel X, the online rail 6 is raised to the same height position as the offline rails 7 and 8.

The C-shaped trolley 10 comprises a trolley 14, a substantially C-shaped frame 15 having an upper arm 15a, a lower arm 15b, and a connecting portion 15c connecting the both. Wheel 12a, 12b
2 a is configured to be rotationally driven by the drive motor 13.

The C-shaped trolley 20 is constructed similarly to the C-shaped trolley 10, and includes a trolley 24, an upper arm 25a and a lower arm 2
5b and a substantially C-shaped frame 25 having a connecting portion 25c for connecting the two. The bogie 24 has wheels 22a and 22b on a vehicle body 21.
3 is configured to be rotationally driven.

The two-dimensional laser rangefinders d1 and d2 are attached to the inner ends of the upper arm 15a and the lower arm 15b of the C-shaped frame 15, respectively. The two-dimensional laser distance meter d4 is attached to the center of the inside of the connecting portion 25c of the C-shaped frame 25.

The arithmetic unit is a laser distance meter d1, d2, d
3, the measured value from d4 and the distance between the laser rangefinders d1 and d2 and the distance between the laser rangefinders d3 and d4 are added and subtracted to obtain the width of the flange Xf of the H-section steel X, The thickness of the web Xw and the center deviation are calculated.

Hereinafter, the operation and effect of the embodiment configured as described above will be described. First, in order to measure the dimensions of the H-section steel X, as shown in FIG. 3, the online rail 6 is aligned with the offline rails 7, 8 at substantially the same height. To do this, the connection shaft 2 is rotated by, for example, forward rotation of the lifting drive motor 3, and the screw jacks 1a, 1b
The elevating platform 4 and the online rail 6 move upward with this, and when the online rail 6 becomes almost the same height as the offline rails 7, 8, the lifting drive motor 3 is stopped. .

Next, the C-shaped carts 10, 20 are moved from the offline rails 7, 8 to the online rail 6. To do this, the drive motors 13, 23 are operated and the wheels 1
When the 2a and 22a are rotated, the C-shaped carts 10 and 20 move to the online rail 6 along the offline rails 7 and 8. And, near the center of the thickness of the flange Xf connected to both sides of the web Xw of the H-section steel X, a laser distance meter d is provided.
When the centers of 1, 1 and d2 coincide, the drive motors 13, 23
To stop. In this case, depending on the height of the web Xw of the H-section steel X, the positions of the C-shaped frames 15, 25 are set at the same distance from the rolling line L, and 1 / of the web height.
The drive motors 13 and 23 are stopped near the distance of 2.

Thereafter, the laser distance meter d attached to the connecting portions 15c, 25c of the C-shaped frames 15, 25
Fine adjustment is made so that the center of 3, d4 substantially matches the center of the width of the flange Xf. This adjustment is performed by the amount of rotation of the lifting drive motor 3.

In this manner, by positioning the laser distance meters d1 to d4 as shown in FIG. 1, the flange width and the web thickness of the H-section steel X conveyed on the conveyance table 30 of the rolling line can be reduced. The measurement can be performed, and the bias of the H-section steel X can be measured by a combination thereof. That is, the measured values measured by the laser distance meters d1 to d4 and the distances between the laser distance meters d1 and d2 and between the laser distance meters d3 and d4 are expressed by:
The dimensions of the H-section steel X can be measured by inputting to an arithmetic unit (not shown) and performing addition and subtraction inside the arithmetic unit.

This measurement operation is performed over the entire length of the H-section steel X, and a value calculated from the relationship between the measurement result and the target size is fed back to various settings of the rolling mill and its peripheral devices to thereby obtain a predetermined value. Rolled products can be obtained.

When the product of the H-section steel X to be rolled has the target dimensions and it is not necessary to measure the dimensions, the drive motors 13 and 23 are operated respectively to immediately move the C-shaped carts 10 and 20. Move to the off-line rails 7, 8 and retreat to the off-line position.

In this case, the C-shaped carts 10 and 20 are configured to drive the carts themselves in the horizontal direction (wheel 1).
Drive motors 13 and 23 for applying a driving force to 2a and 22a)
Since it is only provided, the weight is much lighter than that of the above-mentioned known example (in which the mechanism for driving the device in the vertical direction is integrated), and the configuration is simplified.
The C-shaped carts 10 and 20 can be quickly retracted. Thus, it is possible to prevent a trouble such as a collision with the dimension measuring device due to warpage or bending of the rolled material when the rolling equipment is abnormal.

Further, as shown in FIG.
0 are retracted to different off-line positions, so that they do not interfere with each other and have a structure that allows easy access by people, so that maintenance work in the event of failure or periodic inspection can be easily performed.

As a distance meter, a two-dimensional laser distance meter d1
Since ~ d4 is used, multiple items can be measured by one unit, and the meandering of the H-section steel X can be dealt with.

The positions of the C-shaped carts 10 and 20 may be changed once every several hours, for example. This is because the rolling conditions are changed for each lot. Next, another embodiment of the present invention will be described with reference to FIGS.
FIG. 4 is a perspective view showing a schematic configuration thereof, and is configured as follows by adding a first tracking sensor 35 and a second tracking sensor 36 to the above-described embodiment. The first tracking sensor 35 is disposed at a predetermined position on the entrance side of the transfer table 30, detects that the tip of the H-section steel X has reached, and drives the drive motors 13, 23 and the lifting device EL, respectively. An instruction is given to position the two-dimensional laser distance meters d1 to d4.

The second tracking sensor 36 is provided by the truck 1 from the tracking sensor 35 of the transport table 30.
It is arranged on the 0, 20 side, and when it detects that the tip of the H-section steel X has reached, gives a measurement command to the laser rangefinders d1 to d4 and notifies that the rear end of the H-section steel X has reached. Upon detection, the measuring operations of the laser distance meters d1 to d4 are stopped, and the carts 10 and 20 are moved to the off-line rails 7 and 8.
Side, and gives a lowering command to the lifting device EL.

An apparatus (not shown) for setting the product dimensions of the H-section steel X to this apparatus is provided. The operation and effect of the device configured as described above will be described with reference to the flowchart of FIG. Now, the transport table 30
When the H-shaped steel X is conveyed from and the tip of the H-shaped steel X passes through the tracking sensor 35, the tracking sensor 35 is turned on (S1), and thereafter, the preset H-shaped steel X to be conveyed is set. Is determined to be the same as before (S2). At this time, the tracking sensor 36 is determined to be the same as before.
Detects H-beam X (S3), the laser distance meter d1
To d4 start the measurement operation (S4). When the rear end of the H-section steel X passes through the tracking sensor 36 (S
5), the laser distance meters d1 to d4 are stopped. If it is determined in S2 that the dimensions are not the same as before, the laser distance meters d1 to d4 are positioned (S7). Thereafter, the process sequentially proceeds to S3, S4, S5, and S6. Such an operation is performed every time the H-shaped steel X changes, but the frequency of rolling of the H-shaped steel X becomes coarse because of the lot production.

Thus, each time the dimension of the H-section steel X changes, the positioning of the laser distance meters d1 to d4 is performed,
Since the measurement start and the measurement stop are automatically performed, accurate dimension measurement can be continuously performed. As a result, the H-shaped steel X
In consideration of the behavior of the rolled material such as warping, bending, and twisting during the reversible rolling, which is peculiar to the rolling, safety and maintainability are improved.

The present invention is not limited to the above-described embodiment, and may be, for example, as follows. In the above-described embodiment, the laser rangefinders d1 and d2 are connected to the upper arms 1 of the C-shaped carts 15 and 25.
5a, 25a, attached to the ends of the lower arms 15b, 25b, respectively.
Although they are mounted at the center positions of the connecting portions 15c, 25c of the 5, 25, the present invention is not limited to this, and a desired number may be mounted at a desired position according to the shape of the material to be measured. Further, the rangefinder is not limited to the laser rangefinders d1 to d4, but may be any other noncontact rangefinder.

In the above-mentioned embodiment, the dimension measurement of the hot universal rolling line of the H-section steel was taken as an example. However, the present invention is not limited to this, and the present invention can be applied to the dimension measurement of thick plate rolling, thin plate rolling, and the like. It may be cold, the object to be measured is not limited to the running state, and may be in a stationary state, and may have a shape during rough rolling different from the product shape after rolling, such as H-shaped steel rolling. Continuous and accurate dimension measurement is possible.

It is needless to say that it is desirable to use a material having a low coefficient of thermal expansion which is not easily affected by heat and to provide a heat-proof or cooling treatment for members which are susceptible to thermal deformation due to radiant heat from the rolled material. No.
