Description

Technical Field

[0001] This utility model relates to the technical field of billet measuring devices, and in particular to a billet length measuring device. Background Technology

[0002] A billet length measuring device is a piece of equipment used to accurately measure the length of billets during the steel production process. It typically uses non-contact measurement technologies, such as laser sensors, photoelectric sensors, and encoders, to detect and record the distance the billet moves on the production line in real time. The device consists of sensors, a signal processing system, a transmission mechanism, a display and control system, a mechanical support structure, a calibration system, and auxiliary equipment. The sensors are responsible for collecting the movement information of the billet, the signal processing system analyzes and calculates the data, the transmission mechanism ensures the stable movement of the billet within the measurement area, and the control system is responsible for the operation, display, and alarm functions of the equipment.

[0003] Existing billet length measuring devices still have some problems during use. For example, since billets are usually quite long and heavy, after length measurement, they often need to be moved to the storage area manually or by external hoisting equipment. This operation not only wastes a lot of manpower and resources, but also interferes with the continuous operation of the measuring device, reducing overall work efficiency. Secondly, most existing measuring devices separate the billet handling from the measurement work. This separate operation not only affects the progress of the measurement work, but also reduces the measurement efficiency and makes it impossible to achieve efficient connection in the production process.

[0004] To address these issues, we provide a billet length measuring device. Summary of the Invention

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of inconvenience in transporting the measured steel billet to the storage area, and the separation of measurement and transportation, resulting in low efficiency. Therefore, we propose a steel billet length measuring device.

[0006] To achieve the above objectives, this application adopts the following technical solution: a billet length measuring device, comprising a platform, with support plates fixedly connected to both sides of the top of the platform, and a storage cart provided at the bottom of the platform; a ranging component is provided on the top of the platform, the ranging component including a left baffle slidably connected to one side of the top of the platform, a right baffle slidably connected to the other side of the top of the platform, a first lead screw movably connected to one side of the support plate, the surface of the first lead screw being threadedly connected to the inner cavity of the left baffle, and a second lead screw movably connected to the top of one side of the support plate, the surface of the second lead screw being threadedly connected to the inner cavity of the right baffle, the ranging component being used to measure the length of the billet; a support component is provided on the top of the platform, the support component including a support seat fixedly connected to the bottom of the left and right baffles, a first cylinder fixedly connected to one side of the left baffle, and a clamping plate fixedly connected to the free end of the first cylinder, the support component being used to support the moving billet.

A driving gear is fixedly connected to one side of the surface of the first lead screw, and the driving gear meshes with the driven gear.

[0008] Preferably, a second cylinder is fixedly connected to one side of the support plate, and a push block is fixedly connected to the free end of the second cylinder. A concave groove is provided on one side of the inner cavity of the driven gear, and the surface of the push block fits into the inner cavity of the concave groove.

[0009] Preferably, the platform has grooves on both sides of the top, and a limit rod is fixedly connected to the inner cavity of the groove. A sliding sleeve is slidably connected to the surface of the limit rod, and the top of the sliding sleeve is slidably connected to the bottom side of the left baffle or the right baffle.

[0012] Preferably, the platform has a material discharge port inside, with the bottom of the discharge port located directly above the storage cart.

[0013] The technical effects and advantages of this utility model are as follows: 1. This utility model significantly improves the automation level and efficiency of the billet production line by integrating measurement and handling functions. Specifically, the device is equipped with a storage cart at the bottom of the platform. With the material unloading port design inside the platform cavity, the billet can be directly unloaded into the storage cart after the length measurement is completed, without relying on manual labor or external hoisting equipment. This design not only saves the manpower and time costs of the traditional handling process, but also avoids the efficiency loss caused by the interruption of handling during the measurement process. At the same time, the structure of the cylinder-driven clamping plate and the distance measuring component in the support component ensures the stability of the billet during measurement, further improving the measurement accuracy. Through the integrated process of measurement and unloading, seamless connection of the production process is achieved.

[0014] 2. This utility model solves the efficiency bottleneck problem caused by the functional separation of traditional devices by optimizing the coordination of measurement and conveying. The ranging component adopts a bidirectional adjustable left and right baffle structure, combined with a screw drive and gear synchronization mechanism, which can quickly adapt to steel billets of different lengths and achieve high-precision measurement. The cylinder-driven clamping plate in the support component can fix the position of the steel billet during measurement and avoid sliding errors. In addition, the second cylinder can flexibly control the engagement and disengagement of the driven gear through the cooperation of the push block and the concave groove. The sliding groove and limit rod design on the top of the platform ensures the smooth movement of the baffle. The overall device highly integrates measurement, positioning and conveying functions, reduces the equipment footprint and operation complexity, and is suitable for high-temperature and high-load industrial environments.

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Example 1: Please refer to Figures 1-5This utility model is a billet length measuring device, including a platform 1. Support plates 2 are fixedly connected to both sides of the top of the platform 1. The support plates 2 support a motor 20, a second cylinder 14, and other structures. A conveying groove is provided at the bottom of the support plates 2, extending to the outside of the left baffle 4 and the right baffle 5, to facilitate the conveying of billets from the outside to the top of the platform 1 for length measurement. A storage cart 3 is provided at the bottom of the platform 1, with a handle fixedly connected to one side and self-locking wheels movably connected around its bottom for easy movement. A distance measuring component is provided at the top of the platform 1, including a left baffle 4 slidably connected to one side of the top of the platform 1, a right baffle 5 slidably connected to the other side of the top of the platform 1, a first lead screw 6 movably connected to one side of the support plates 2, the surface of the first lead screw 6 being threadedly connected to the inner cavity of the left baffle 4 and movably connected to the inner cavity of the right baffle 5, the rotation of the first lead screw 6 not causing the right baffle 5 to move, and a second lead screw 7 movably connected to the top of one side of the support plates 2. The threads of lead screw 6 and lead screw 7 are opposite, causing the left baffle 4 and right baffle 5 to move in opposite directions when the driving gear 13 meshes with the driven gear 12. This allows the steel billet on the top of the support seat 8 to fall into the storage car 3 through the discharge port. The surface of the second lead screw 7 is threadedly connected to the inner cavity of the right baffle 5 and is used to measure the length of the steel billet by a distance measuring component. A support component is provided on the top of the platform 1. The support component includes a support seat 8 fixedly connected to the bottom of the left baffle 4 and the right baffle 5. The support seat 8 can support the steel billet, and one side of the support seat 8 extends to the outside of the left baffle 4 or the right baffle 5, so that the distance measuring instrument 19 can measure the length of the steel billet. A first cylinder 9 is fixedly connected to one side of the left baffle 4, and a clamping plate 10 is fixedly connected to the free end of the first cylinder 9. The clamping plate 10 driven by the first cylinder 9 can move the steel billet when the left baffle 4 moves, ensuring that the steel billet can be completely transported to the top of the platform 1 for convenient measurement. The support component is used to support the moving steel billet.

[0023] Example 2: Please refer to Figures 1-5Based on Embodiment 1, a limiting strip 11 is fixedly connected to one side of the surface of the second lead screw 7. A driven gear 12 is slidably connected to the surface of the limiting strip 11. The limiting strip 11 allows the driven gear 12 to slide on the surface of the second lead screw 7, enabling the driven gear 12 to mesh with the driving gear 13 at different positions to accommodate steel billets of different lengths. When the driving gear 13 meshes with the driven gear 12, the rotation of the first lead screw 6 will drive the second lead screw 7 to rotate. Since the threads of the two are opposite, the left baffle 4 and the right baffle 5 move in opposite directions. At this time, if the first cylinder 9 drives... When the clamping plate 10 releases the clamping limit on the steel billet, the steel billet will separate from the support seat 8 due to the opposite movement of the left baffle 4 and the right baffle 5. Therefore, the measured steel billet can be dropped into the storage cart 3 for subsequent transportation to the storage area. A drive gear 13 is fixedly connected to one side of the surface of the first lead screw 6. The drive gear 13 meshes with the driven gear 12. A second cylinder 14 is fixedly connected to one side of the support plate 2. A push block 15 is fixedly connected to the free end of the second cylinder 14. The push block 15 engages with the inside of the concave groove 16, so that the second cylinder 14 can drive the driven gear 12 on the surface of the second lead screw 7. The sliding connection will not affect the rotation of the driven gear 12 driving the second lead screw 7, and the concave groove 16 can limit the push block 15. The concave groove 16 is opened on one side of the inner cavity of the driven gear 12, and the surface of the push block 15 fits in the inner cavity of the concave groove 16. Sliding grooves are opened on both sides of the top of the platform 1. The inner cavity of the sliding groove is fixedly connected to the limiting rod 17. The surface of the limiting rod 17 is slidably connected to the sliding sleeve 18. The limiting rod 17 and the sliding sleeve 18 can support and limit the left baffle 4 and the right baffle 5. The top of the sliding sleeve 18 is slidably connected to the bottom side of the left baffle 4 or the right baffle 5. A rangefinder 19 is fixedly connected to the side. The rangefinder 19 is an existing structure and will not be described in detail here. A reflective mark is fixedly connected to the area of ​​the lens of the rangefinder 19 on the side of the left baffle 4 so that the rangefinder 19 can illuminate this area to perform accurate length measurement. The rangefinder 19 is used to measure the length of the steel billet. A motor 20 is fixedly connected to one side of the support plate 2. The output end of the motor 20 is fixedly connected to one end of the first lead screw 6. A material drop port is opened in the inner cavity of the platform 1. The material drop port allows the steel billet after the length is measured to fall into the corresponding storage cart 3. The bottom of the material drop port is located directly above the storage cart 3.

[0024] Working principle: After the steel billet is fed into the top of platform 1 by the conveying equipment, the support seat 8 immediately supports its weight. The motor 20 drives the first lead screw 6 to rotate, which drives the left baffle 4 to move smoothly along the limit rod 17 in the slide groove. At the same time, the first cylinder 9 pushes the clamping plate 10 to clamp the steel billet, ensuring its stable positioning and assisting in pushing the steel billet completely into the measurement area. The rangefinder 19 on the right baffle 5 emits a laser to the preset reflective mark on the left baffle 4. The total length of the steel billet is calculated through the high-precision reflected signal. After the measurement is completed, the system switches the working mode, the second cylinder 14 starts, the push block 15 is embedded in the concave groove 16 of the driven gear 12, driving the gear to mesh, and the motor 20 reverses. The left and right baffles 5 are separated in opposite directions simultaneously, the first cylinder 9 retracts the pressing plate 10 simultaneously, and the support seat 8 unfolds to form a discharge gap. Under the action of gravity, the steel billet slides precisely into the storage car 3 with self-locking wheels at the bottom through the discharge port, completing the automated transfer. The entire process is controlled by the coordinated control of the screw-gear transmission system, cylinder linkage mechanism and photoelectric ranging module to achieve seamless connection of measurement, positioning and unloading. The limit rod 17 and sliding sleeve 18 are designed to eliminate mechanical vibration error, reflective markings compensate for laser scattering in high temperature environment, and the modular structure design ensures the stability of the equipment under heavy load and high temperature conditions, and the overall efficiency is steadily improved.

[0025] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
