Description

Technical Field

[0001] This utility model relates to the field of steel processing and manufacturing technology, and in particular to a weighing sensor detection fixture. Background Technology

[0002] In the steel processing and manufacturing industry, high-precision load cells are one of the key pieces of equipment to ensure the smooth operation of the production process. However, existing technologies have many problems in the calibration and testing of load cells. Currently, the calibration of under-tank process scales in ironmaking plants is usually done by comparing the output values ​​of portable force sensors with those of hopper scales. However, this method cannot meet the calibration requirements of high-precision load cells because portable force sensors themselves may have errors, leading to inaccurate calibration of the under-tank scales. In addition, the purchase of load cells is usually done through bidding, and the quality of the sensors can only be judged by visual inspection and product manuals upon receipt, without verifying their actual performance. This may result in quality problems with the sensors received, affecting subsequent production use. Traditional calibration devices can usually only handle small weights and cannot meet the calibration requirements of large-tonnage sensors, while the measuring range of under-tank scales is usually large. During operation, the lifting and operation of the weighing platform are prone to shaking or tipping, posing safety hazards. Moreover, existing calibration and testing methods require multiple adjustments and repeated operations, which are time-consuming, labor-intensive, and inefficient, failing to meet the needs of large-scale production.

Detailed Implementation

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0031] Reference Figure 1-4 As shown, this utility model provides a weighing sensor detection fixture, including:

[0032] The weighing platform base plate 1 has multiple boxes 2 for connecting to the lower plate.

[0033] The weighing platform 7 has multiple upper connecting plate boxes 8 installed below it, and the upper connecting plate boxes 8 and the lower connecting plate boxes 2 are in a one-to-one correspondence in their vertical positions; both the lower connecting plate box 2 and the upper connecting plate box 8 are plug-in type connecting boxes, which are used to quickly replace the sensor 15 under test of different specifications.

[0034] A guide connecting rod 22 is provided through the lower connecting hole 5 of the weighing platform base plate 1 and the upper connecting hole 12 of the weighing platform surface 7, and a locking member 24 is provided at the end of the guide connecting rod 22 that extends out of the weighing platform surface 7.

[0035] Hydraulic jacks 14, including multiple jacks, are all mounted on the weighing platform base plate 1 via jack mounting bases 3;

[0036] Weight 21 is loaded onto the base plate 1 of the weighing platform and is used to compare with the output value of the sensor 15 to be tested.

[0037] In this embodiment, there are five lower connecting plate boxes 2 and three upper connecting plate boxes 8, with the three lower connecting plate boxes 2 and the three upper connecting plate boxes 8 arranged in a triangular pattern.

[0038] like Figure 5-7 As shown, the insert-type connector box includes an insert connector 16 and a plug box 20. The plug box 20 has a slot. The insert connector 16 has limiting holes 161 that are adapted to both ends of the sensor under test 15. The insert connector 16 is inserted into the plug box 20 to fix the sensor under test 15.

[0039] In practical applications, the insert connector 16 can be replaced according to different specifications of the sensor under test 15, so that the limiting hole on the insert connector 16 matches the sensor under test 15.

[0040] Preferably, each of the insert connectors 16 is provided with a first locking hole 17, and the insert box 20 is provided with a second locking hole 18; when the first locking hole 17 on the insert connector 16 is aligned with the second locking hole 18 on the insert box 20, the insert connector 16 and the insert box 20 are fixed by locking screws.

[0041] Furthermore, an anti-tipping limiting component is provided between the weighing platform base plate 1 and the weighing platform surface 7 to prevent the weighing platform surface 7 from tipping over during the lifting process.

[0042] In this embodiment, the anti-tipping limiting component includes a wedge block 13 and an anti-tipping block 4 adapted to the wedge block 13. The wedge block 13 is disposed at the bottom of the weighing platform 7, and the anti-tipping block 4 is disposed on the weighing platform base plate 1.

[0043] In addition, I-beams 9 are provided on both the platform surface 7 and the base plate 1 of the weighing platform to reinforce the platform surface 7. After reinforcement, the platform surface 7 and the base plate 1 of the weighing platform are more stable, reducing deformation during the loading of weights 21 and calibration of the sensor under test 15. This allows the platform to support weights 21 up to 12,000 kg, meeting the calibration requirements of large-tonnage sensors under test 15 and enhancing the versatility and load-bearing capacity of the device.

[0044] In this embodiment, four hydraulic jacks 14 are included. A jack connecting sleeve 10 is provided on the weighing platform base plate 1 for fixing the hydraulic jacks 14. The multiple hydraulic jacks 14 are evenly distributed to ensure the stability of the weighing platform 7 during the lifting process. Furthermore, the design of the jack connecting sleeve 10 facilitates the installation and fixing of the hydraulic jacks 14, improving the convenience of operation.

[0045] Furthermore, a lifting ring 23 is provided on the guide connecting rod 22. The design of the lifting ring 23 facilitates the handling of the entire tooling using a crane or other lifting equipment, improving the convenience and safety of handling.

[0046] When using the test fixture based on the above structure: loosen the locking part 24 to the maximum position, without removing the guide connecting rod 22, connect the power connecting pipe of the hydraulic jack 14 to the outside of the weighing platform through the galvanized pipe 6 on the weighing platform base plate 1, and apply pressure to the hydraulic jack 14 from the outside. After the hydraulic jack 14 rises, the connecting part enters the jack connecting sleeve 10 set at the bottom of the weighing platform 7, lifting the weighing platform 7. At this time, the guide connecting rod 22, wedge block 13, and anti-tilting block 4 work together to ensure that the position of the weighing platform 7 will not change significantly during the rising process.

[0047] After the platform 7 is lifted, select the sensor to be tested 15, determine the diameter of the connecting device of the sensor to be tested 15, select the corresponding size of the insert connector 16 and insert it into the insert box 20 of the upper connecting plate box 8 and the lower connecting plate box 2 respectively. After the insert connector 16 is inserted into the insert, the first locking hole 17 on the insert connector 16 coincides with the second locking hole 18 on the mounting insert box 20. At this time, lock it and complete the installation of the sensor to be tested 15 or portable force measuring instrument.

[0048] To restore the hydraulic jack 14 to its initial state, in actual design, the height of the hydraulic jack 14 and the combined height of the wedge block 13 and the anti-tilt block 4 need to be determined based on the minimum size of the sensor under test 15. This ensures that when the hydraulic jack 14 is restored to its initial state, the force-bearing point of the entire weighing platform 7 is connected and supported by the sensor under test 15. At the same time, it is necessary to check whether the wedge block 13 and the anti-tilt block 4 are in contact due to small displacement. If there is contact, the sensor installation steps should be repeated for adjustment.

[0049] After adjusting to a completely non-contact state, remove the guide connecting rod 22. At this point, the weight 21 can be loaded. After the weight 21 is loaded, the output value of the sensor under test 15 is displayed and compared with the standard value to determine whether the sensor under test 15 or the portable force measuring instrument is qualified. The maximum load is 12000kg weight 21.

[0050] The weighing sensor calibration fixture based on this invention can test complete sets of sensors (three or four sensors per set), but cannot test individual sensors. Due to the use of a plug-in connector, sensors of different diameters can be quickly replaced for testing, greatly improving testing efficiency and shortening the calibration and testing cycle. Simultaneously, an anti-tipping limit component and guide connecting rod 22 are designed to ensure the stability of the weighing platform 7 during lifting and operation, significantly improving operational safety and reducing the risk of accidents caused by equipment instability. Furthermore, the weighing platform 7 and the weighing platform base plate 1 are reinforced, capable of supporting weights 21 up to 12,000 kg, meeting the calibration requirements of large-tonnage sensors and enhancing the versatility and load-bearing capacity of the device. Overall, this invention not only improves the accuracy and efficiency of calibration and testing but also reduces operational difficulty, providing an efficient, reliable, and safe calibration and testing solution for the steel processing and manufacturing industry.

[0051] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
