Description

Technical Field

[0001] The invention relates to a gap monitoring technology for a railway track switch machine, and in particular to a method for vibration testing and high and low temperature testing of a gap monitoring sensor. Background Art

[0002] At present, the vibration test or high and low temperature test of the gap monitoring sensor is usually carried out by installing it on the switch machine, and performing the vibration test and high and low temperature test together with the switch machine.

[0003] The existing solution to the vibration test and high and low temperature test of the gap monitoring sensor is to install the sensor on the switch machine, and then install the switch machine on a vibration table or place it in a high and low temperature chamber, so that the sensor can be tested together with the switch machine. This solution has several disadvantages: 1. Inconvenient operation. The switch machine is large in size, heavy in weight, and inconvenient to carry; 2. High cost. The transportation cost of the switch machine is high, and the switch machine needs to be reserved for testing, which also increases the cost; 3. Low efficiency. Different models of switch machines can only be installed with sensors of corresponding models, and each switch machine can only be installed with one sensor, which greatly limits the test efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a method for testing the vibration test and high and low temperature test of a notch monitoring sensor, so as to meet the simultaneous testing of four notch monitoring sensors, and the method has low production cost, small size, and convenient installation, and can greatly improve the efficiency of the sensor vibration test and high and low temperature test.

[0005] The objective of the present invention is achieved in this way. It relates to a method for vibration test and high and low temperature test of a notch monitoring sensor, which is characterized by comprising a test tooling bottom plate, a first support plate, a second support plate, a ZD6 notch monitoring displacement sensor, an S700K notch monitoring displacement sensor, a test rod, a ZD9 notch monitoring displacement sensor, a ZY7 notch monitoring displacement sensor, a collection extension, an extension fixture, an extension mounting plate, and a limit plate; the test tooling bottom plate has circular holes of the same size and layout as the parts of the vibration test bench, when performing a vibration test, other parts are directly fixed on the vibration test bench, and the parts are used when performing a high and low temperature test.

[0006] There are two first support plates and one second support plate, which are connected to the bottom plate of the test fixture by bolts, so that two identical first support plates and one second support plate form two intervals respectively, and the test rod is fixedly supported by the two first support plates and one second support plate in the two intervals; the first support plate is Z-shaped, and one surface of the Z-shape is in contact with and connected to the bottom plate of the test fixture, and the bottom surfaces of the two first support plates are directed to the left.

[0007] The upper right side of the two Z-shaped first support plates is used to fix the ZD9 notch monitoring displacement sensor and the ZY7 notch monitoring displacement sensor respectively. The magnetic heads of the ZD9 notch monitoring displacement sensor and the ZY7 notch monitoring displacement sensor are kept less than 2 mm away from the upper surface of the test rod.

[0008] The outer side of the vertical surface of the first outer support plate is fixed with bolts to connect the ZD6 gap monitoring displacement sensor, and the second support plate is L-shaped, and the vertical surface of the L-shaped corner of the second support plate is fixed with bolts to connect the S700K gap monitoring displacement sensor.

[0009] There are two limit plates, which are angular structures and are fixed at both ends of the test fixture bottom plate, respectively. The limit plate at the right end is used to fix and limit the other end face of the horizontally placed S700K notch monitoring displacement sensor.

[0010] The extension fixtures are one on each side, and the two extension fixtures are respectively connected to the first support plate in the middle with bolts. The two extension fixtures fix the extension mounting plate, fix the collection extension through the extension mounting plate, and install the collection extension in the card slot of the extension fixture.

[0011] The two ends of the test rod are of different thicknesses. The thick end is inserted into the square hole groove of the ZD6 notch monitoring displacement sensor, and the thin end is inserted into the square hole groove of the S700K notch monitoring displacement sensor.

[0012] The surface of the test rod is grooved, and a magnetic strip is installed in the groove to test whether the ZD6 gap monitoring displacement sensor and the S700K gap monitoring displacement sensor function normally.

[0013] It further includes a left and right limit plate, each of which has threaded holes on its surface. The left and right limit plates are connected to the bottom plate of the test fixture by bolts, and the moving distance of the test rod is adjusted by the screws.

[0014] When conducting high and low temperature tests, the test rod is passed through the ZD6 notch monitoring displacement sensor, the first support plate, the second support plate and the S700K notch monitoring displacement sensor respectively. The position of the test rod is adjusted so that the magnetic strip installed on the test rod is located directly below the ZD6 notch monitoring displacement sensor, the S700K notch monitoring displacement sensor, the ZD9 notch monitoring displacement sensor and the ZY7 notch monitoring displacement sensor. The position of the rod is adjusted at different temperatures. The ZD6 notch monitoring displacement sensor, the S700K notch monitoring displacement sensor, the ZD9 notch monitoring displacement sensor; and the ZY7 notch monitoring displacement sensor can collect the rod displacement data, which can be read by the handheld device.

[0015] When conducting a vibration test, fix the sensor cable with a cable tie and support both ends of the test rod with bolts installed on the limit plate to conduct the vibration test.

[0016] The advantage of the present invention is that one test fixture can meet the requirements of four notch monitoring displacement sensors, namely, ZD6 notch monitoring displacement sensor 4, S700K notch monitoring displacement sensor 5, test rod 6, ZD9 notch monitoring displacement sensor 7, and ZY7 notch monitoring displacement sensor 8, and a collection extension to simultaneously perform vibration tests or high and low temperature tests, and has the characteristics of modular design, low cost, high efficiency, easy installation, easy transportation, easy operation, and intuitive experimental results.
