Abstract
Description
Technical Field
[0001] The utility model relates to the field of hot billet measurement, in particular to a portable device for quickly and accurately measuring the size of a hot billet. Background Art
[0002] The quality of the control of the continuous casting billet's external dimensions directly affects the production rhythm and product quality. Continuous casting billets that do not meet the external dimension standards will lead to abnormal steel extrusion on the cooling bed, difficulty in crane lifting and rolling into the furnace, affecting the production rhythm. In addition, large dimensional deviations / fluctuations will lead to uncontrolled product quality and affect the quality of rolled products / finished products. Billets with excessive external dimensions must be discovered and picked out in a timely manner during production.
[0003] At present, the measurement of the external dimensions of continuous casting billets mainly relies on manual visual observation, which has poor accuracy; or during production, workers are required to get close to the hot billets and manually hold a steel ruler on the hot billets to measure the thickness and width of the continuous casting billets. This method is slow and inefficient, and is close to the high-temperature billets, has a harsh environment, poor safety, and a high temperature load on the workers. Utility Model Content
[0004] The utility model aims to provide a portable device for quickly and accurately measuring the size of hot blanks.
[0005] To achieve this purpose, the utility model adopts the following technical solutions:
[0006] A portable device for quickly and accurately measuring the size of a hot billet is provided, comprising two gripping rods, the middle parts of the two gripping rods are hinged, the gripping rods are divided into a front half and a rear half along the central hinge, the front half of each gripping rod is a telescopic structure, and a clamping rod is fixedly provided at the front end of the gripping rod, and when the front half of the gripping rod is telescopically adjusted, the clamping rod will be driven to move together.
[0007] Furthermore, a tape measure is arranged between the tails of the two grips, one end of the tape measure is fixedly connected to one of the grips, and a ring sleeved with the outer edge of the tape measure is arranged on the other grip.

[0019] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0020] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings will be omitted, enlarged or reduced, and do not represent the size of the actual product.
[0021] Reference Figures 1 to 4A portable device for quickly and accurately measuring the size of a hot blank is shown, comprising two grips 1, the middle parts of the two grips 1 are hinged, and the grips 1 are divided into a front half and a rear half along the central hinge. The front half of each grip 1 is a telescopic structure, and a clamping rod 2 is fixedly arranged at the front end of the grip 1. When the front half of the grip 1 is telescopically adjusted, the clamping rod 2 will be driven to move together. When measuring the size of the hot blank 3, the hot blank 3 can be clamped by the two clamping rods 2, and then the distance between the tails of the two grips 1 is measured, and then the length of the hot blank 3 can be obtained by calculation. The specific calculation process is as follows: the length of the front half is set to L1, the length of the rear half is set to L2, the distance between the front ends of the two grips 1 is set to d1, and the distance between the tails of the two grips 1 is set to d2, that is, L1 / L2=d1 / d2, and d1=L1×d2 / L2 can be obtained. The distances of L1 and L2 are known at the beginning, that is, after knowing the distance of d2, the distance of d1 can be obtained. This calculation method can avoid manually holding a steel ruler on the hot billet to measure the thickness and width of the continuous casting billet. When the clamping rod 2 clamps the hot billet 3, the clamping rod 2 and the hot billet 3 are in a completely fitted state, that is, the distance between the inner sides of the two clamping rods 2 is the distance between the ends of the two gripping rods 1.
[0022] When the length of the hot blank 3 changes, the corners of the grip rod 1 and the clamp rod 2 need to clamp the two ends of the hot blank 3, so that the measurement result is the most accurate. This is mainly because the distances of thickness and width are different when measuring the hot blank 3. Therefore, it can only be guaranteed that the clamp rod 2 can completely fit the hot blank 3 when measuring one position. Ensuring that one position can fit makes it easier for workers to operate the device to clamp the hot blank and move it to other positions.
[0023] By enabling the front half of the grip rod 1 to be telescopically adjusted, it can be ensured that the clamping rod 2 can completely fit and clamp the hot blank 3 within a certain width range.
[0024] A tape measure 6 is provided between the tails of the two grips 1, one end of the tape measure 6 is fixedly connected to one of the grips 1, and a ring is provided on the other grip 1 to be sleeved with the outer edge of the tape measure 6. When the two grips 1 are pulled apart, the worker can quickly judge the distance between the ends of the two grips 1 by the scale of the tape measure 6, that is, the value of d2 can be obtained more quickly.
[0025] A handle ring 4 is fixedly provided on the outer side of the tail of the two grip rods 1 , and a worker can better grasp the grip rod 1 through the handle ring 4 .
[0026] The front half of the grip 1 includes a fixed rod 1a and a telescopic rod 1b. The fixed rod 1a is fixedly connected to the rear half of the grip 1. One side of the telescopic rod 1b is slidably connected to one side of the fixed rod 1a. The fixed rod 1a and the telescopic rod 1b are fixedly connected by a clamp (not shown in the figure). When adjusting the length, the telescopic rod 1b is pushed to slide horizontally along the fixed rod 1a. When the sliding position is adjusted, it is locked by the clamp. The fixed rod 1a and the telescopic rod 1b can also be fixedly connected by a connection method such as bolt connection. There are many ways to slide the telescopic rod 1b and the fixed rod 1a, among which a slot can be provided on the telescopic rod 1b and a clamp strip can be provided on the fixed rod 1a.
[0027] The length of the rear half of the grip rod 1 is 100 mm, the length of the fixed rod 1a is 100 mm, and the sliding adjustment distance between the fixed rod 1a and the telescopic rod 1b is 0-100 mm. The above-mentioned length can better adapt to the operation of workers.
[0028] The telescopic rod 1b and the clamping rod 2 are integrally formed. With this structure, an angle can be formed at the connection between the telescopic rod 1b and the clamping rod 2. The angle is conducive to the end of the hot blank 3 being inserted, which is convenient for measurement.
[0029] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
