Description

TECHNICAL FIELD

[0001] The utility model relates to the field of casting blank surface measurement technology, especially a kind of casting blank on-line width measuring tool. BACKGROUND

[0002] In the current steel industry, many steel plants will be equipped with double-flow slab production equipment, which will continuously output slabs during production. As one of the important forms of steel products, the accuracy of the slab's external dimensions is crucial for subsequent processing and customer use. However, there are significant deficiencies in the measurement of slab external dimensions during actual production.

[0003] Specifically, after the completion of slab production, these steel plants lack efficient and accurate surface detection and dimension measurement instruments. The traditional method is to use a tape measure for manual measurement by staff after the slab is offline. This measurement method is not only inefficient but also easily influenced by human factors, resulting in significant measurement errors.

[0004] According to technical requirements, the width of the casting blank needs to be measured every 5 to 6 furnaces after the first furnace of slab production. However, due to the backwardness of measurement methods, it is often difficult to effectively monitor the external dimensions of the casting blank in a timely manner. Especially in the case of fluctuating casting speed, the width of the casting blank is prone to overwidth, resulting in external dimensions of the casting blank that do not meet technical requirements. This size discrepancy not only affects product quality and customer satisfaction but also increases the difficulty and cost of subsequent processing.

[0005] To improve the speed and accuracy of casting blank width measurement, some enterprises have designed a casting blank width measurement tool. This tool mainly includes a fixed caliper and a movable sleeve. One end of the fixed caliper is fixedly installed with a clamping plate. The fixed caliper has clear size lines along its length direction for easy reading. The movable sleeve is slidably fitted on the fixed caliper, allowing it to move back and forth along the length direction of the fixed caliper. The movable sleeve is provided with an inverted U-shaped handle for easy gripping and pushing, and another clamping plate corresponding to the clamping plate at the end of the fixed caliper. Both clamping plates are perpendicular to the fixed caliper. This structure of the casting blank width measurement tool has the following shortcomings: 1. During measurement, the operator needs to manually push the movable sleeve to clamp the casting blank for width measurement. During this process, the operator's hand will move closer to the high-temperature casting blank due to the need to hold the inverted U-shaped handle on the movable sleeve. This operating method greatly increases the risk of burns for the operator, with low safety. 2. In actual operation, it is difficult to ensure that the fixed caliper is parallel to the width direction of the casting blank. The fixed caliper can easily be inclined in the horizontal plane. This inclination can cause a large deviation between the measurement result and the actual width of the casting blank, affecting the accuracy of the measurement. SUMMARY

[0006] The utility model discloses a kind of casting blank online width measuring tools, and the tool can solve the problem of low safety, large measurement deviation of existing casting blank online width measuring tool.

[0007] To solve the above problems, the utility model adopts the technical scheme that the casting blank online width measuring tool includes fixed caliper, movable sleeve and clamping plate, the fixed caliper is provided with size line, the movable sleeve is sleeved on the fixed caliper, the fixed caliper and the movable sleeve are respectively provided with the clamping plate for clamping casting blank, the movable sleeve is connected with long handle operating lever and horizontal rod, the long handle operating lever includes connecting section and long handle section, one end of the long handle section is fixedly connected with the movable sleeve through connecting section, the other end of the long handle section extends towards the holding end of the fixed caliper, and the moving direction of the long handle section is parallel to the sliding direction of the movable sleeve;The horizontal rod has observation section for aligning the side edge of casting blank, and the observation section is perpendicular to the movable sleeve.

[0008] In the technical scheme of the above-mentioned casting blank online width measuring tool, the more specific technical scheme can also be that the bottom of the two clamping plates is provided with anti-inversion wing plate, and the two anti-inversion wing plates are oppositely arranged.

[0009] In some possible embodiments, a movable clamp plate is arranged between the anti-inversion wing plate and the fixed caliper, and a spring is connected between the movable clamp plate and the anti-inversion wing plate.

[0010] In some possible embodiments, the movable clamp plate has horizontal clamping part and downwardly inclined guide part.

[0011] In some possible embodiments, the horizontal rod includes auxiliary observation section vertically connecting the movable sleeve and the observation section, and the auxiliary observation section is closer to the observation side relative to the connecting section.

[0012] In some possible embodiments, the holding end of the fixed caliper and the long handle operating lever is provided with anti-slip heat insulation sleeve.

[0013] In some possible embodiments, the fixed caliper is made of circular tube.

[0014] Due to the adoption of the above technical scheme, the utility model has the following beneficial effects compared with the prior art:

[0015] 1、The measuring tool is connected with a long handle operating rod on the movable sleeve, so that the operator can operate remotely through the long handle operating rod during measurement, the operator's hands can be away from the high-temperature casting blank, the risk of scalding is greatly reduced, and the safety of operation is improved; the horizontal rod provides an observation reference for the operator, which helps to ensure that the fixed caliper remains parallel to the width direction of the casting blank during measurement, and the operator can adjust the horizontal position of the fixed caliper in time by observing whether the horizontal rod is horizontal with the side edge of the casting blank, so as to avoid measurement deviation and improve the accuracy of measurement.

[0016] 2、The anti-turning wing plate can effectively prevent the long handle operating rod and the movable sleeve connected therewith from turning over due to gravity, which not only may cause errors in the measurement process and affect the accuracy of data, but also may hit the equipment or the operator and cause safety accidents.

[0017] 3、The movable clamping plate is provided and connected with the anti-turning wing plate through the spring, so that the width measurement can be flexibly adapted to casting blanks of different thicknesses; the structure design of the movable clamping plate enables casting blanks of different thicknesses to be easily slid into the clamping area, so that the movable clamping plate can more smoothly approach and clamp the casting blank.

[0018] 4、The horizontal rod is provided with a mutually perpendicular observation section and an auxiliary observation section close to the observation side, so that the operator can more intuitively observe the relative positional relationship between the tool and the casting blank from different angles, which helps to quickly judge whether the position of the width measuring tool needs to be adjusted, thereby improving the measurement efficiency.

[0019] 5、The fixed caliper is made of a circular tube, which can reduce the contact with the surface of the casting blank, thereby reducing friction and wear, and can also effectively reduce the overall weight of the tool, so that the operation is more flexible and convenient, and the efficiency is improved.

DETAILED DESCRIPTION

[0024] The utility model will be further described in detail below in combination with the drawings of the embodiments:

[0025] Figures 1 to 3 The cast blank on-line width measuring tool shown mainly comprises a fixed caliper 1, a movable sleeve 6, a clamping plate 2, an anti-inversion wing plate 5, a horizontal rod 7 and a long handle operating rod 9, wherein the fixed caliper 1 serves as the main structure of the measuring tool, and a size line is arranged on the surface of the fixed caliper 1 to facilitate direct reading of the measured data. The movable sleeve 6 is sleeved on the fixed caliper 1 and can slide along the length direction of the fixed caliper 1; the clamping plate 2 for clamping the two side edges of the cast blank 10 is welded and fixed at one end of the fixed caliper 1 and the same end of the movable sleeve 6; the two clamping plates 2 are provided with the opposite anti-inversion wing plates 5 at the bottom to enhance the clamping stability and prevent the movable sleeve 6 and the fixed caliper 1 from being accidentally inverted under the influence of the self-gravity of the long handle operating rod 9 and the horizontal rod 7. The long handle operating rod 9 and the horizontal rod 7 are fixedly connected to the movable sleeve 6; the long handle operating rod 9 facilitates the operator to remotely push the movable sleeve 6 to slide, and the horizontal rod 7 is used for observing the measuring position of the width measuring tool to ensure the accuracy of the measurement.

[0026] In some possible embodiments, the fixed caliper 1 is made of a round pipe, one end of which is a holding end, and a non-slip heat insulation sleeve 8 is sleeved on the holding end to enhance the comfort and safety of use; the other end is a measuring starting end, and a clamping plate 2 is fixed vertically on the measuring starting end. Clear size lines are drawn or engraved on the surface of the fixed caliper 1, and the starting position of the size lines is aligned with the inner surface of the clamping plate 2 at the measuring starting end of the fixed caliper 1 to facilitate accurate measurement and data reading.

[0027] The long handle operating rod 9 comprises a long handle section 9-1 and a connecting section 9-2, one end of the long handle section 9-1 is connected to the movable sleeve 6 through the connecting section 9-2, the other end extends towards the holding end of the fixed caliper 1, and the connecting section 9-2 is perpendicular to the movable sleeve 6 and the long handle section 9-1. The moving direction of the long handle section 9-1 is parallel to the sliding direction of the movable sleeve 6, which facilitates the operator to push the movable sleeve 6 to slide. Preferably, the holding end of the long handle operating rod 9 is also provided with a non-slip heat insulation sleeve 8.

[0028] The horizontal rod 7 has an observation section 7-1, which is arranged perpendicularly to the movable sleeve 6 and is used for aligning the side edge 10-1 of the cast blank to ensure the measurement accuracy. In some possible embodiments, the horizontal rod 7 further comprises an auxiliary observation section 7-2, which is connected perpendicularly to the movable sleeve 6 and the observation section 7-1 and is closer to the observation side relative to the connecting section 9-2 of the long handle operating rod 9, which facilitates the operator to observe the measurement condition from different angles.

[0029] In order to make the width measuring tool suitable for more different thickness of the casting slab 10 to measure the width, in some possible embodiments, the distance between the anti-turning wing plate 5 and the fixed caliper 1 is increased, thereby expanding the clamping space in the vertical direction. In the clamping space, the movable clamping plate 3 is arranged between the anti-turning wing plate 5 and the fixed caliper 1, and the movable clamping plate 3 is connected with the anti-turning wing plate 5 through the spring 4. The movable clamping plate 3 has a horizontal clamping part and an inclined downward guide part. The horizontal clamping part is used to clamp the casting slab 10 in the vertical direction, and the spring 4 provides a stable clamping force to ensure the accuracy and stability during the measurement. The inclined downward guide part guides the casting slab 10 to quickly and accurately enter the clamping space between the fixed caliper 1 and the movable clamping plate 3, thereby facilitating the quick and stable clamping of the casting slab 10 with different thickness.

[0030] In use, the operator stands beside the casting slab transport roller and holds the anti-slip heat insulation sleeve 8 of the fixed caliper 1, and places the fixed caliper 1 on the surface of the casting slab 10 along the width direction of the casting slab 10. The operator carefully observes the position of the horizontal rod 7 and adjusts the angle of the fixed caliper 1 to ensure that the horizontal rod 7 is parallel to the side edge 10-1 of the casting slab, as shown in Figure 3 Then the casting slab 10 is clamped between the movable clamping plate 3 at the measuring starting end and the fixed caliper 1 and abuts against the clamping plate 2, and the long handle operating rod 9 is pushed to move the movable clamping sleeve 6 along the fixed caliper 1 to the casting slab 10, until the casting slab 10 is clamped between the movable clamping plate 3 at the end of the movable clamping sleeve 6 and the fixed caliper 1 and abuts against the clamping plate 2 at the end, and the width measuring tool can clamp the casting slab 10 from the vertical direction and the width direction of the casting slab. After clamping the casting slab 10, the operator can observe the size line on the fixed caliper 1 aligned with the movable clamping sleeve 6, and read the numerical value corresponding to the size line, which is the accurate width of the casting slab 10. After the measurement is completed, the long handle operating rod 9 is moved in the opposite direction to release the clamping state of the width measuring tool, and as the movable clamping plate 3 gradually exits, the casting slab 10 will completely escape from the clamping range of the width measuring tool. At this time, the operator can safely remove the width measuring tool and record the measured width value for subsequent analysis and processing.

[0031] The present slab on-line width measuring tool has simple structure, convenient operation, accurate measurement and strong universality, greatly improves the measuring efficiency and precision. At the same time, the workload of the operator is greatly reduced, not only realizes the on-line measurement of the slab, replaces the traditional off-line measurement mode, but also significantly improves the inspection efficiency of the slab. The tool can more quickly complete the fixed-length measurement of the slab width, ensures the width stability of the slab in the production process, thereby effectively improves the qualified rate of the slab quality inspection. Especially important is that this improvement does not introduce any external equipment or increase additional investment, but saves the equipment cost, greatly reduces the production cost. In addition, the width measuring tool with high reliability and simple equipment structure realizes the zero maintenance requirement, further improves the production efficiency and economic benefit.
