Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a digital display notch detection device for an electric switch machine and a use method thereof. Background Art

[0002] The electric switch machine indicator gap is an important parameter in the daily maintenance of the switch machine. It reflects the close contact between the switch point rail and the base rail, and plays a vital role in the operation of the switch. If the gap value of the switch machine indicator rod is too large or too small, the switch machine will not be locked, thus affecting the normal operation of the switch.

[0003] At present, the daily maintenance of the electric switch machine indication gap in rail transit in various places mainly relies on manual regular or irregular inspections. Generally, during the intervals between train operations, an application for maintenance work is made / the skylight is opened, and the electric switch machine cover is checked by visual inspection and feeler gauge detection. This method has a certain impact on rail transit operations, and the workload of maintenance personnel is large. The process is cumbersome, time-consuming, and inefficient. Affected by the on-site environment, it is easy to cause manual misjudgment. Bead-type, photoelectric, and video-type gap detection sensors can also be used to implement remote gap monitoring, but to varying degrees, there are problems such as high equipment cost, great construction difficulty, increased maintenance workload, low detection accuracy, complex reference position adjustment, susceptibility to electromagnetic interference, and frequent false alarms.

[0004] The patent application document with publication number CN220062801U discloses a switch gap detection device, which detects the width of the switch gap by manually inserting measuring bodies of different thicknesses into the switch gap. The device is essentially an improved version of the feeler gauge detection method mentioned above. However, due to the technical limitations of the feeler gauge detection method itself, it is necessary to open the switch cover for manual measurement, and it is not possible to measure in real time. It can only perform qualitative measurement of the gap width, and the measurement cannot display accurate values. Summary of the invention

[0013] A method for using a digital display notch detection device for an electric switch machine comprises the following steps:

[0014] Step 1, when the locking rod 1 of the electric switch is pulled in and the locking rod 2 is extended and the electric switch is locked, read the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the extended locking rod 2. When it is displayed as 0.00mm, it proves that the gap of the extended locking rod 2 has not shifted; when the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the extended locking rod 2 is not 0.00, it proves that the gap of the extended locking rod 2 has shifted, the positive and negative values ​​represent the direction of the shift, and the absolute value of the value represents the amount of the shift; when the amount of the shift exceeds the specification requirements, adjust the gap;

[0015] Step 2. When the locking rod 1 and the locking rod 2 of the electric switch are both in the retracted position and the electric switch is locked, read the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the retracted locking rod 1. When it is displayed as 0.00mm, it proves that the gap of the retracted locking rod 1 has not shifted; when the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the retracted locking rod 1 is not 0.00, it proves that the gap of the retracted locking rod 1 has shifted.

[0017] Step 1, after the electric switch is pulled until the locking rod 1 is pulled in and the locking rod 2 is extended and the electric switch is locked, adjust the internal notch of the locking rod 2 of the electric switch so that the notch of the locking rod 2 meets the specification requirements.

[0019] Step 3, after the electric switch is pulled until the locking rod 1 is pulled in and the locking rod 2 is extended, the electric switch is locked, and the internal notch of the locking rod 1 is adjusted to make the notch of the locking rod 1 meet the specification requirements. This is the reference position of the locking rod 1.

[0020] Step 4, calibrate the digital display moving gate detection module B, press the ZERO reset button B-4 of the digital display moving gate detection module B corresponding to the locking rod 1 pulled in, and the LCD screen B-2 on the side of the digital display moving gate detection module B corresponding to the locking rod 1 pulled in will display 0.00mm. At this time, the gap monitoring calibration of the locking rod 1 is completed.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1.

[0023] 2. In the present invention, after the relative displacement between the fixed gate A detected by the locking rod and the moving gate B-1 detected by the fixed digital display moving gate detection module B, the capacitance changes, and the charge coupling method of the capacitor converts the mechanical displacement into an electrical signal, showing the principle of mechanical displacement. The offset measurement of the switch gap is changed from the original qualitative measurement to quantitative measurement, and the measurement accuracy can reach 0.01mm, which is more accurate.

[0024] 3. The present invention can realize a quick calibration of the gap detection device when it is put into use for the first time or when an error occurs, through the data clearing function of the clearing button of the digital display moving grid detection module B.

[0025] 4. The present invention monitors the displacement of the locking rod detection fixed grid A that moves with the locking rod through the digital display moving grid detection module B installed above the locking rod of the electric switch. After one calibration, the offset direction and offset amount of the retracted locking rod 1 and the extended locking rod 2 of the electric switch can be known by observing the value of the liquid crystal screen B-2 of the digital display moving grid detection module B, and then the offset direction and offset amount of the indicating notch of the retracted locking rod 1 and the extended locking rod 2 of the electric switch can be intuitively known; the staff can complete the indicating notch inspection work without opening the end cover 5 of the electric switch, and it will not affect the normal operation of rail transit; the device is set on each electric switch to facilitate the staff to intuitively detect the indicating notch of the electric switch.

The present invention monitors the displacement of the locking rod detection fixed grid A which moves with the locking rod by means of a digital display moving grid detection module B installed above the locking rod of the electric switch machine, thereby realizing intuitive detection of the indication gap of the electric switch machine.

When it is displayed as 0.00mm, it proves that the gap of the extended locking rod 2 has not shifted; when the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the extended locking rod 2 is not 0.00, it proves that the gap of the extended locking rod 2 has shifted, the positive and negative values ​​represent the direction of the shift, and the absolute value of the value represents the amount of the shift; when the amount of the shift exceeds the specification requirements, adjust the gap;

[0062] Step 2. When the locking rod 1 and the locking rod 2 of the electric switch are both in the retracted position and the electric switch is locked, read the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the retracted locking rod 1. When it is displayed as 0.00mm, it proves that the gap of the retracted locking rod 1 has not shifted; when the value of the LCD screen B-2 of the digital display moving gate detection module B corresponding to the retracted locking rod 1 is not 0.00, it proves that the gap of the retracted locking rod 1 has shifted. The positive and negative values ​​represent the direction of the shift, and the absolute value of the value represents the amount of shift. When the amount of shift exceeds the specification requirements, adjust the gap.
