[0002] During the steelmaking and continuous casting process, the billet needs to be cut into different lengths of fixed-length billets by flame cutting according to the requirements of the steel rolling order. Due to some factors during the cutting process, the billet will be cut obliquely from a rectangular to a diamond-shaped large surface. At this time, the billet diagonal will be out of tolerance, resulting in poor billet shape after rolling, and large plate heads at the head and tail. To a certain extent, it causes low yield of rolled steel plates, waste after shearing, and increased costs.

DETAILED DESCRIPTION OF THE INVENTION

[0022] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following provides a detailed description of the specific embodiments of the present utility model in conjunction with the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] Please refer to Figures 1 to 7 , an embodiment of the present application provides a novel device for offline measurement of the diagonal of the large face of a steel billet, including a scale main body 1. The scale main body 1 is provided in two and is distributed vertically. Activity frames 2 are sleeved on both scale main bodies 1. The scale main body 1 linearly moves along the length direction of the scale main body 1 within the activity frame 2. The two activity frames 2 are rotatably connected. A first auxiliary walking wheel 3 is installed at the bottom of the lower activity frame 2. The first auxiliary walking wheel 3 is provided in four and is distributed in a rectangle, facilitating the support of the device to move back and forth on the surface of the steel billet 4. A baffle 5 for abutting against the cross-section of the steel billet 4 is installed at one end of the lower scale main body 1. The baffle 5 is a flat plate body. A stop head 6 for abutting against the corner of the steel billet 4 is installed at one end of the upper scale main body 1. The bottom heights of both the baffle 5 and the stop head 6 are lower than the bottom height of the first auxiliary walking wheel 3. In this way, when the first auxiliary walking wheel 3 contacts the upper end surface of the steel billet 4, the baffle 5 and the stop head 6 can contact the edge of the steel billet 4. By setting the baffle 5 and the stop head 6, the scale main body 1 can be conveniently and accurately clamped to the head and corner of the measured steel billet 4 under the condition of single-person operation.

[0024] To enable the scale main body 1 to linearly move within the activity frame 2, please refer to Figure 3 , two rows of guide wheels 7 are rotatably installed in the activity frame 2. The two rows of guide wheels 7 are respectively located on both sides of the scale main body 1. The number of each row of guide wheels 7 is two. A ring groove 8 matching the scale main body 1 is provided on the wheel surface of the guide wheel 7. A part of the scale main body 1 is located inside the ring groove 8, which can facilitate the support of the scale main body 1 by the guide wheels 7. The scale main body 1 is in rolling connection with the guide wheels 7. By setting the guide wheels 7, it is convenient to push and pull the scale main body back and forth.

[0025] To achieve the rotational connection of the two activity frames 2, please refer to Figure 1 and Figure 4 , a bearing 9 is provided between the two activity frames 2. The two activity frames 2 are rotatably connected through the bearing 9. By setting the bearing 9, it is convenient for the two scale main bodies 1 to perform turning operations.

[0026] To prevent the activity frame 2 from detaching from the scale main body 1, please refer to Figures 1 to 3 , as well as Figure 5 and Figure 6, a stop block 10 is fixed to both the end of the lower scale body 1 away from the baffle 5 and the end of the upper scale body 1 away from the stop head 6. The stop block 10 is provided in two, which can prevent the movable frame 2 from detaching from the scale body 1.

[0027] When the stop head 6 catches the corner of the billet 4, to facilitate the upper scale body 1 to rotate at an appropriate angle so that the upper scale body 1 is aligned with the diagonal position of the billet 4, a clamping groove 11 with an included angle greater than 90 degrees, preferably 135 degrees, is formed inside the stop head 6. In this way, it can adapt to billets 4 of various different sizes. The stop head 6 can stably catch the corner of the billet 4 and is also convenient for the upper scale body 1 to rotate by a large angle, facilitating the alignment of the upper scale body 1 with the diagonal position of the billet 4. If the included angle is less than or equal to 90 degrees, it cannot rotate when the stop head 6 catches the corner of the billet 4.

[0028] To facilitate the movement of the scale body 1, a handle 12 is fixed to both the end of the lower scale body 1 away from the baffle 5 and the end of the upper scale body 1 away from the stop head 6. By holding the handle 12, it is convenient to push and rotate the scale body 1.

[0029] For accurate reading, please refer to Figures 1 to 3 , and Figure 5 and Figure 6 , a scale pointer 13 is slidably installed on both scale bodies 1. By setting the scale pointer 13, accurate measurement marks can be made, facilitating data reading. The stop block 10 can also prevent the scale pointer 13 from detaching from the scale body 1.

[0030] For stable pushing of this device to move on the billet 4, please refer to Figure 1 and Figure 2 , a cushion block 14 is installed at the bottom of the lower scale body 1, and a second auxiliary walking wheel 15 is installed at the lower end of the cushion block 14. The bottom end of the second auxiliary walking wheel 15 is flush with the bottom end of the first auxiliary walking wheel 3. By setting the cushion block 14, the height increase of the first auxiliary walking wheel 3 caused by the movable frame 2 can be compensated, so that the bottom end of the second auxiliary walking wheel 15 can be flush with the bottom end of the first auxiliary walking wheel 3. The number of the second auxiliary walking wheels 15 and the first auxiliary walking wheels 3 is both set to four, and the second auxiliary walking wheels 15 and the first auxiliary walking wheels 3 are both distributed in a rectangle, which can stably support the movement and stop of this device.

[0031] The working principle of this embodiment: During use, please refer to Figure 1 , by grasping the handle 12, this device is pushed onto the billet 4 to be measured by using the first auxiliary walking wheel 3 and the second auxiliary walking wheel 15;

[0032] After reaching one end of the head of the billet 4, the baffle 5 is abutted against the position approximately at the center of the longitudinal edge of the billet 4 to realize the positioning of the lower scale body 1;

[0033] With the assistance of the upper guide wheel 7, the upper scale main body 1 is pushed outwards. With the assistance of the bearing 9, the upper scale main body 1 is rotated so that the stop head 6 is stuck at the right-angle position of the billet 4. Then, the angle of the upper scale main body 1 is adjusted so that the center line of the upper scale main body 1 is aligned with the diagonal position of the billet 4. Please refer to Figure 5 and Figure 6 , adjust the position of the scale pointer 13 to read the data and obtain the data of one diagonal of the billet 4;

[0034] Then, perform the same operation to measure the other diagonal of the billet 4 and obtain the data of the other diagonal of the billet 4;

[0035] After the measurement is completed, rotate the upper scale main body 1 to align the directions of the upper and lower scale main bodies 1, which is convenient for storage.
