Description

Technical Field

[0001] This utility model belongs to the field of sensor technology and relates to a device for rapidly detecting magnetostrictive displacement sensors. Background Technology

[0002] In recent years, the automation level of coke oven vehicles has reached a high level. To achieve fully automatic locomotive operation, the hydraulic cylinders of the locomotives use built-in magnetostrictive displacement sensors to detect the actual stroke of the hydraulic cylinders. The stroke is different for each furnace. Magnetostrictive displacement sensors for hydraulic cylinder detection offer high measurement accuracy, strong reliability, and high safety, fully meeting the on-site locomotive operation requirements. However, if a magnetostrictive displacement sensor malfunctions during production, it will severely impact production time. Therefore, regular inspection of the magnetostrictive displacement sensor is necessary to determine if a fault has occurred. However, inspecting and replacing magnetostrictive displacement sensors presents significant challenges. Utility Model Content

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A device for rapidly detecting a magnetostrictive displacement sensor includes a support plate on which a magnetostrictive displacement sensor is mounted. The magnetostrictive displacement sensor includes a waveguide rod arranged along the length of the support plate, a detection magnetic ring sleeved on the waveguide rod, and a connecting rod connected to the detection magnetic ring. A retaining clip is provided at the end of the connecting rod away from the detection magnetic ring. A support frame for supporting the magnetostrictive displacement sensor under test is provided on one side of the waveguide rod. An electrically operated telescopic rod is arranged on the support plate along the length of the support plate, and the electrically operated telescopic rod is connected to the middle of the connecting rod.

[0006] Furthermore, the support plate is horizontally positioned.

[0007] Furthermore, the waveguide rod is horizontally positioned.

[0008] Furthermore, the electric telescopic rod and the waveguide rod are arranged parallel to each other.

[0009] Furthermore, the connecting rod and the waveguide rod are arranged perpendicular to each other.

[0010] Furthermore, the support frame includes a support rod, and the top end of the support rod is provided with a U-shaped strut.

[0011] Furthermore, the support rod is arranged vertically.

[0012] The advantages of this invention are as follows: by using one magnetostrictive displacement sensor to test another magnetostrictive displacement sensor, if the values ​​are consistent, it indicates that the tested sensor is normal; if they are inconsistent, it indicates that the tested sensor is faulty. The test results are accurate, efficient and fast; the structure is simple and the manufacturing cost is low. Attached Figure Description

Detailed Implementation

[0017] The present invention will now be described in detail with reference to the accompanying drawings:

[0018] like Figure 1 and 2 As shown, a device for rapidly detecting a magnetostrictive displacement sensor includes a horizontally arranged support plate 1. A magnetostrictive displacement sensor 2 is mounted on the support plate 1. The magnetostrictive displacement sensor 2 includes a waveguide rod 201 horizontally arranged along the length of the support plate. A detection magnetic ring 202 is sleeved on the waveguide rod 201. The detection magnetic ring 202 is connected to a connecting rod 3 perpendicular to the waveguide rod. A clamping clip 4 is provided at the end of the connecting rod 3 away from the detection magnetic ring 202. The clamping clip 4 is used to hold the magnetic ring mounted on the magnetostrictive displacement sensor being tested. The connecting rod 3 can drive the detection magnetic ring 202 and the magnetic ring mounted on the magnetostrictive displacement sensor to move simultaneously. One side of the waveguide rod 201 is provided with a support for the detected magnetic ring. The support frame 5 for measuring the magnetostrictive displacement sensor includes a vertically arranged support rod 501, which is fixed to the support plate 1. The top of the support rod 501 is provided with a U-shaped support rod 502. In practical use, one end of the waveguide rod to be tested can be placed on the support rod 502. The support frame 5 can support the waveguide rod of the magnetostrictive displacement sensor to be tested. After the waveguide rod to be tested is placed on the support frame 5, the waveguide rod to be tested and the waveguide rod 201 can be arranged parallel to each other. An electric telescopic rod 6 is provided on the support plate 1 along the length direction of the support plate 1 and is arranged parallel to the waveguide rod 201. The electric telescopic rod 6 is connected to the middle of the connecting rod 3, and the connecting rod 3 can be moved by the electric telescopic rod 6.

[0019] The method of using this utility model is as follows:

[0020] First, the waveguide rod of the magnetostrictive displacement sensor 7 to be tested is placed on the support frame 5, making the waveguide rod to be tested parallel to the waveguide rod 201. Then, the magnetic ring to be tested is placed on the waveguide rod to be tested and clamped by the clamping clip 4 (e.g., Figure 3 As shown in the figure, the electric telescopic rod 6 can then drive the connecting rod 3 to move, which in turn drives the detection magnetic ring 202 and the detected magnetic ring to move simultaneously. Then, observe the values ​​of the magnetostrictive displacement sensor 2 and the detected magnetostrictive displacement sensor 7. If the values ​​are consistent, it means that the detected sensor is normal. If the values ​​are inconsistent, it means that the detected sensor is faulty. After a period of use, the magnetostrictive displacement sensor 2 on the support plate 1 can be tested to ensure the accuracy of the test results.

[0021] This device uses one magnetostrictive displacement sensor to detect another magnetostrictive displacement sensor, providing accurate, efficient, and fast detection results.
