Description

Technical Field

[0001] This utility model relates to a billet size measuring device, specifically a device for measuring the length and width dimensions of billets, belonging to the field of measuring tool technology. Background Technology

[0002] In slab continuous casting production, the width of the slab is frequently measured to determine if it meets requirements. Currently, the conventional methods for inspecting the dimensions of hot-charged slabs are either by inspectors using a long rod at the side of the continuous casting machine's roller conveyor or by measuring after the red-hot steel has cooled on-site. When measuring red-hot steel, the slab is extremely hot, yet inspectors need to be close to it, and the environment near the roller conveyor is poor, posing safety risks such as burns and falls. Furthermore, the high temperature prevents prolonged close-range observation of the measurement values. Additionally, the infrequent frequency of these high-temperature measurements increases the risk of slabs with insufficient dimensions being passed on to the next process. Measuring after the red-hot steel has cooled on-site occupies limited storage space and impacts production efficiency.

[0003] Patent CN210220895U describes a high-temperature billet size measuring tool. First, the first sleeve is moved, causing the first and second clamping plates to clamp the billet. Then, the adjusting screw is tightened, fixing the first sleeve to the outside of the first rod. Pulling the handle compresses the spring, separating the second clamping plate from the billet, allowing the device to be easily removed. Afterward, a measuring tape is used to measure the distance between the two clamping plates, which is the current hot width of the billet. The entire measurement process is safe and convenient. However, the tool is still close to the billet during use, inevitably subjecting it to high temperatures, which could affect safety. Furthermore, after using the tool, a measuring tape is needed to measure the distance between the two clamping plates to measure the billet's dimensions; it cannot measure dimensions in real time, thus its ease of use needs improvement. Also, it can only measure the length or width of the billet, not both simultaneously.

[0004] Therefore, developing a device that can overcome the above defects for measuring the length and width of billets has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device for measuring the length and width of billets. This device ensures that the billet size can be verified without cooling without affecting the billet pulling of the continuous casting machine. It is highly safe, can quickly measure the length and width of hot billets at the same time, and is convenient and quick to use.

[0006] To solve the above technical problems, this utility model provides a device for measuring the length and width dimensions of billets, including a moving trolley, a telescopic rod, and a scale. The scale is mounted on the moving trolley via the telescopic rod and has a graduated scale.

[0007] The mobile cart includes a frame with four swivel wheels at the bottom, a handrail on one side, and two telescopic rods symmetrically arranged at the top of the frame, allowing the marker to be adjusted up and down.

[0008] The telescopic rod is equipped with a marker rod, which has a U-shaped structure, including a horizontal marker rod and side marker rods located on both sides of the horizontal marker rod. One of the side marker rods is slidably set on the horizontal marker rod, and a stop block is moved on the side marker rod for moving to measure and display the size of the blank.

[0009] The further defined technical solution of this utility model is:

[0010] Furthermore, in the aforementioned device for measuring the length and width dimensions of billets, a horizontal marker is horizontally mounted on a telescopic rod, with one side marker fixedly mounted at one end of the horizontal marker and the other side marker slidably mounted at the other end.

[0011] In terms of technical effect, one measuring rod in this utility model is fixed while the other is interactive, which facilitates the measurement of blanks of different sizes and has good applicability.

[0012] In the aforementioned device for measuring the length and width of billets, a sliding groove is provided along the length of the transverse marker, and one end of one of the side markers is slidably set in the sliding groove by a slider so that the side marker slides on the transverse marker;

[0013] One end of the measuring rod extends outward to form a fixed end. The fixed end extends into and passes through the sliding groove to connect with the slider. A circular working groove is provided on the side of the slider away from the fixed end.

[0014] Technical advantages: The horizontal marker of this utility model is provided with a sliding groove to facilitate the movement of one of the side markers, which facilitates the measurement of the length or width of the billet and is suitable for billets of different sizes. The movement causes the side marker to come into contact with the billet, resulting in more accurate measurement and better adaptability. At the same time, a working groove is provided on one side of the slider to facilitate the operator to move the side marker with a stick, avoiding operation at high temperatures and ensuring safety.

[0015] In the aforementioned device used for measuring the length and width dimensions of billets, the telescopic rod is an electrically controlled telescopic rod.

[0016] In terms of technical benefits, this utility model adopts an electric remote-controlled telescopic rod, which synchronously controls the raising and lowering of the two telescopic rods, making it easier to adjust and cope with blanks of different sizes, and making it more convenient and faster to use.

[0017] In the aforementioned device for measuring the length and width dimensions of billets, a stop block is slidably sleeved on a side marker rod, and the side of the stop block facing the billet extends outward to form a stop post for abutting against the billet for measurement.

[0018] Technical advantages: This utility model uses a stop block that moves on a scale for measurement, making it easier to view the displayed dimensions. At the same time, a stop post is provided on one side of the stop block so that it can contact the blank to reach the representative length position during movement, thus improving the accuracy of the measurement.

[0019] In the aforementioned device for measuring the length and width of billets, the scale on the transverse marker and the fixed side marker is at the zero point at the connection point, and the scale on the sliding side marker is at the zero point at the connection point with the transverse marker.

[0020] The technical advantage is that the fixed end is set as the zero point of the scale, which facilitates measurement. The size can be measured by moving the other sliding side scale rod, which is convenient and quick.

[0021] In the aforementioned device used for measuring the length and width dimensions of blanks, the caster wheel is a caster wheel with a brake.

[0022] In terms of technical benefits, this utility model uses universal wheels with brakes, which facilitates braking and stability after movement into position, making measurement easier and improving accuracy.

[0023] In the aforementioned device used for measuring the length and width dimensions of billets, the moving trolley is equipped with reinforcing ribs.

[0024] Technically, this utility model features reinforcing ribs on the mobile trolley to improve stability and facilitate normal operation.

[0025] The beneficial effects of this utility model are:

[0026] In this invention, if the horizontal marker is used to measure the width of the billet, then the side marker is used to measure the length of the billet. The length is measured by a stop block, and simultaneous measurement on both sides facilitates correction and improves measurement accuracy. When measuring the length, one of the side markers can be slid, which acts as a stop block. It can measure both length and width at the same time, is suitable for billets of different sizes, is convenient and quick to use, has high accuracy, avoids high temperature, and has good safety.

[0027] The device of this invention allows inspectors to measure the dimensions of hot-filled billets at any time without having to be close to them. This improves production efficiency, reduces the shortage of billet storage space on site, ensures accurate measurement, and effectively avoids safety risks.

[0028] This invention effectively solves the problem of low measurement frequency of hot-charged billets, which requires on-site cooling measurement and affects low production efficiency, while avoiding safety hazards during high-temperature measurement. Attached Figure Description

[0035] This embodiment provides a device for measuring the length and width dimensions of a billet, the structure of which is as follows: Figure 1 As shown, it includes a mobile trolley, a telescopic pole 2, and a marker. The marker is mounted on the mobile trolley via the telescopic pole 2, and the marker is equipped with a graduated scale 3.

[0036] The mobile trolley includes a frame 11 with reinforcing ribs 9, four universal wheels 12 with brakes at the bottom of the frame 11, a handrail 13 on one side of the frame 11, and two electric remote-controlled telescopic rods 2 symmetrically arranged at the top of the frame 11, so that the pole can be adjusted up and down.

[0037] The marker has a U-shaped structure, including a horizontal marker 4 and side markers 5 located on both sides of the horizontal marker 4. The horizontal marker 4 is horizontally set on the telescopic rod 2. One side marker 5 is fixedly installed at one end of the horizontal marker 4, and the other side marker 5 is slidably installed at the other end. A stop block 6 is movable on the side marker 5 for moving to measure and display the size of the blank.

[0038] The scale 3 on the horizontal marker 4 and the fixed side marker 5 has a zero point at one end of its connection. The scale 3 on the sliding side marker 5 has a zero point at one end of its connection with the horizontal marker 4.

[0039] In this embodiment, the structure is as follows: Figure 2 and 4As shown, the horizontal marker 4 is provided with a sliding groove 7 along its length direction, and one end of one of the side markers 5 is slidably disposed in the sliding groove 7 by a slider 8 so that the side marker 5 slides on the horizontal marker 4;

[0040] Structure as Figure 3 and 4 As shown, one end of the measuring rod 5 extends outward to form a fixed end. The fixed end extends into and passes through the sliding groove 7 and is welded or bonded to the slider 8 for fixed connection. A circular working groove is provided on the side of the slider 8 away from the fixed end for the operator to insert a stick into the moving side of the measuring rod 5 for measurement.

[0041] In this embodiment, the structure is as follows: Figure 5 As shown, the stop block 6 is slidably sleeved on the side marker 5. The stop block 6 extends outward from the side facing the billet to form a stop post 61 for abutting against the billet for measurement.

[0042] In practice, the trolley is moved to the vicinity of the billet using the casters. Once it reaches its destination, it is braked and fixed. The height of the billet is visually assessed, and the telescopic rod is adjusted to a suitable height. Then, the fixed side marker is placed against one side of the billet. The stop blocks on the side marker are all set at the rear before use. The stop blocks on the fixed side marker are moved so that the stop posts on the stop blocks are against one side of the billet, and its length is measured. The length of the sliding side marker is measured in the same way. The two measurements are corrected. If they are inconsistent, they are measured again. A rod is inserted into the working groove, and the sliding side marker is moved so that it is against the side wall of the billet. The transverse marker is used to measure the width of the billet. After the measurement is completed, the trolley is removed.

[0043] This utility model is mainly applied to the steelmaking production line, specifically for measuring the dimensions of red-hot steel after continuous casting. It can achieve measurement without the need for the billet to cool down. Economic benefits include: improved production efficiency, reduced safety hazards, and reduced quality risks associated with short-length billets flowing into the next process.

[0044] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
