Description

Technical Field

[0001] The utility model belongs to the field of auxiliary tools for axle counting system testing, in particular to a tool for assisting an axle counting simulation wheel to be perpendicular to a rail. Background Art

[0002] Currently, during the testing and adjustment of axle counting systems, a simulated wheel is required to simulate the magnetic flux lines generated by a magnetic head when a train passes through the axle counting point. The simulated wheel, or auxiliary wheel used, typically consists of an aluminum alloy body, acrylic support frames, and an adjustable support plate. The two support frames are located on either side of the body, positioned to abut the rails. The support plate is centered on the other side of the body, abutting the magnetic head receiving end. The aluminum alloy body is adjusted to a vertical position by adjusting the extension of the support plate to simulate the state of the wheel cutting the magnetic flux lines when passing the magnetic head. Existing simulated wheel tools require visual adjustment of the aluminum alloy body angle, but cannot be precisely perpendicular to the rails during adjustment. Furthermore, the adjustment range is inconsistent between tests, resulting in deviations in the measured data. This makes the simulated wheel angle ineffective for accurate data tracking during routine maintenance. Furthermore, since two magnetic heads require adjustment at a single axle counting point, adjusting the simulated wheel angle for both heads is time-consuming.

[0003] Therefore, a new technology is needed to solve the problems of inaccurate measurement data and long measurement time in the test and adjustment of the axle counting system in the prior art. Utility Model Content

The tool has a simple structure and is easy to use. It can make the simulation wheel perpendicular to the rail, thereby ensuring that the posture of the simulation wheel is consistent with the posture of the wheel cutting the magnetic field when the train passes. The measurement data is accurate, and the measurement time can be reduced, which has the effect of improving test efficiency.

[0026] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0027] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. In addition, the terms "upper," "lower," "left," and "right" used in this utility model are only used with respect to the relative positions of the components of the utility model in the accompanying drawings.

[0028] Reference Figure 1, a tool for assisting the axle counting simulation wheel to be perpendicular to the rail, includes a fixing frame 1, the fixing frame 1 is provided with a slot 13 with an upward opening for the simulation wheel to be embedded, the slot 13 has a first side wall 11 and a second side wall 12 arranged oppositely, and the simulation wheel can abut against the first side wall 11 when it is between the first side wall 11 and the second side wall 12, and the fixing frame 1 is horizontally provided with a pressing plate 7 and a bottom plate 3 on one side close to the second side wall 12, the bottom plate 3 is located at the bottom of the fixing frame 1, the pressing plate 7 is detachably fixed above the bottom plate 3, the lower surface of the pressing plate 7 and the upper surface of the bottom plate 3 are parallel to each other and are both perpendicular to the first side wall 11, the pressing plate 7 can be tightly connected to the upper surface of the rail, and the upper surface of the bottom plate 3 can abut against the lower surface of the rail and are parallel to each other, that is, the upper surface of the bottom plate 3 fits the bottom surface of the rail. When the upper surface of the base plate 3 is in close contact with the bottom surface of the rail, the first side wall 11 is perpendicular to the upper surface of the base plate 3. Therefore, the simulated wheel abutting the first side wall 11 is perpendicular to the bottom surface of the rail. Specifically, when the simulated wheel is inserted into the slot 13 and abutted and secured against the first side wall 11, the simulated wheel can remain relatively perpendicular to the rail surface, maintaining the same vertical angle when testing different magnetic heads at the same axle counting point. Because the auxiliary axle counting simulated wheel perpendicular to the rail tool of this solution can be used between the two magnetic heads, it only needs to be installed once when testing at the same axle counting point, avoiding the time-consuming repeated angle adjustments when testing on two magnetic heads.

[0029] During axle counting and maintenance, if long-term tracking of fault data and comparison with the previous data is required, a unified data reference is required. The auxiliary axle counting simulation wheel in this solution is perpendicular to the rail. This tool ensures that the simulated wheel's posture is consistent with the posture of the wheel cutting the magnetic field when the train passes. When using the auxiliary device for measurement, the two measurements can be as close as possible to the actual cutting magnetic field value.

[0030] Generally, when debugging the two magnetic heads at an axle counting point, the simulation wheel needs to be adjusted and used once. The simulation wheel also needs to be used once during the retest after debugging. That is, the simulation wheel angle needs to be adjusted four times to complete all test items at an axle counting point. If each adjustment takes about 2 minutes, the total time is 8 minutes. However, the auxiliary axle counting simulation wheel and the tool perpendicular to the rail using this solution only take 2 minutes, and no subsequent angle adjustment is required, which can save 6 minutes of working time. Taking a subway operating line with 13 stations and 50 kilometers of mileage as an example, there are about 330 axle counting devices in total, that is, each round of inspection can save 1,980 minutes of working time, which can save a lot of time.

The pressure plate 7 is tightly connected to the upper surface of the rail via the third fixing member 16, maintaining the upper surface of the base plate 3 parallel to the lower surface of the rail, thereby maintaining the first sidewall 11 of the measuring plate 2 perpendicular to the rail surface.

[0039] S1. Use two countersunk screws to pass through the openings in clamping plate 5 and then through the openings in the lower part of partition plate 4 to secure it to measuring plate 2. Then use two hexagonal screws to pass through the multiple rows of screw holes in fixing plate 6 and secure it to the screw holes in the middle of clamping plate 5. Use two screws to screw into the upper screw holes in clamping plate 5, and use one screw to screw into the top screw hole in fixing plate 6.

[0040] S2. Select a location midway between the two magnetic heads at the axle counting point. Place the inner bottom edge of the bottom plate 3 of the auxiliary axle counting tool perpendicular to the rail near the bottom of the rail. Simultaneously, tighten the screws on the top of the pressure plate 7 to secure the entire tool to the rail, with the side of the measuring plate 2 perpendicular to the rail. Place the simulated wheel in the slot 13 above the partition 4, between the measuring plate 2 and the clamping plate 5.
