[0024] like Figure 1-Figure 5 As shown, the wheel operation simulation device 3 includes: a crawler 309 for simulating the rotation of the wheel; a crawler steel attachment plate 311 for simulating the effect of the steel wheel passing over the axle counter sensor 7; a crawler main plate 310 for connecting with the crawler steel attachment plate 311 and driving the crawler steel attachment plate 311 to rotate; a main rotating wheel 301 for driving the crawler 309 to rotate; a main rotating shaft 303 connected to the main rotating wheel 301 and driving the main rotating wheel 301 to rotate; and a slave rotating wheel 304 The main shaft 305 is connected to the crawler 309, rotates with the crawler 309, and plays a role in supporting the crawler 309; the slave rotating shaft 305 is connected to the slave rotating wheel 304; the spindle motor 306 is connected to the main rotating shaft 303, and provides the main rotating wheel 301 with the power of rotation; the spindle motor seat 307 is connected to the upper and lower position adjustment plate 2, and is used to fix the spindle motor 306; the position sensor 308 is installed on the upper and lower position adjustment plate 2, and is used to detect the rotation speed of the crawler 309 and the position of the crawler steel attachment plate 311;

[0025] like Figure 1 , Figure 4As shown, the up-down position adjustment plate 2 includes: a lifting handle 205, which is used to drive the up-down position adjustment plate 2 to move up and down; a position sensor through hole 206, which is used to install a position sensor 308; a locking nut 203, which is used to press the up-down position adjustment plate 2 by rotation; a locking screw 204, which is used to pass through the longitudinal adjustment long hole 201, and is connected with the left positioning hole 107 of the positioning and fixing beam and the right positioning hole 108 of the positioning and fixing beam; the longitudinal adjustment long hole 201 is used for the up-down position adjustment plate 2 to move up and down along the longitudinal adjustment long hole 201; the main rotating shaft through hole 207 is used for the main rotating shaft 303 to pass through; the secondary rotating shaft through hole 208 is used for the secondary rotating shaft 305 to pass through;

[0026] The left positioning hole 107 of the positioning and fixing beam and the right positioning hole 108 of the positioning and fixing beam are internal thread structures, and the locking screw 204 passes through; the longitudinal adjustment long hole 201 can be tightened with the left positioning hole 107 of the positioning and fixing beam and the right positioning hole 108 of the positioning and fixing beam, and the upper and lower position adjustment plates 2 are pressed with the locking nuts 203. In this way, the relative height between the lower edge of the track 309 and the axle counter sensor 7 can be controlled, thereby realizing more accurate wide-range automated measurement of the axle counter sensor 7.

[0027] The above structure can effectively simulate the state of wheels passing on the track, and determine whether the axle counter sensor 7 is operating normally by detecting the data feedback of the axle counter sensor 7.

[0028] The important innovation of the present invention lies in the wheel structure of the crawler structure, which can simulate the state of the rail wheel passing through the axle counter sensor 7 while minimizing the overall volume of the entire axle counter auxiliary detection system, making the axle counter auxiliary detection system more portable;

[0029] like Figure 6 , Figure 7 As shown, the interior of the axle counter sensor 7 includes two proximity sensors, and the two proximity sensors have a certain distance therebetween, namely, a first proximity sensor 5 and a second proximity sensor 8. When the wheel 9 passes the axle counter sensor 7, if the sensing order of the proximity sensors is: the first proximity sensor 5 senses effectively, the first proximity sensor 5 and the second proximity sensor 8 sense effectively at the same time, and the second proximity sensor 8 senses effectively, it proves that the wheel 9 is running from left to right. If the sensing order of the proximity sensors is: the second proximity sensor 8 senses effectively, the second proximity sensor 8 and the first proximity sensor 5 sense effectively at the same time, and the first proximity sensor 5 senses effectively, it proves that the wheel 9 is running from right to left, thereby determining the direction of the vehicle's running. If the performance of a proximity sensor is degraded or damaged, there is no corresponding feedback signal and it must be replaced.

[0030] The above detection process requires that at a certain distance, there are two proximity sensors that are simultaneously effective; if the wheel structure of the crawler structure is not selected, then Figure 6 As shown, when the diameter of the rotating wheel is made smaller for portability, it is impossible to achieve a state in which the two proximity sensors are simultaneously effective, that is, it is impossible to simulate the scene in which the wheel 9 passes the axle counter sensor 7. The rotating wheel structure of the track structure in the present invention allows the track 309 to run in a straight line between the two main rotating shafts 301 and the secondary rotating shaft 304, and the track steel attachment plate 311 attached to the track 309 is connected to form a plane, which can better simulate the state of the wheel passing.

[0031] Comparison of the performance of the portable track axle counter auxiliary detection system in the present invention with the actual working conditions:

[0032] According to the data, the wheel of a railway passenger car is generally 910 mm. The principle of adapting to the detection of the axle counter sensor 7 is that the diameter of the wheel 9 is large enough, and a sufficient area can be formed above the first proximity sensor 5 and the second proximity sensor 8 at a certain moment and at a position 20 mm away from the upper surface of the axle counter sensor 7 so that the first proximity sensor 5 and the second proximity sensor 8 can sense the wheel 9 at the same time. Figure 6 shown.

[0033] However, in order to realize portable detection of the axle counter sensor 7, a wheel with a diameter of 910 mm is not suitable, so a small wheel with a smaller diameter is used. However, the diameter of the small wheel is not enough to form a sufficient area at a distance of 20 mm from the upper surface of the axle counter sensor 7 so that the first proximity sensor 5 and the second proximity sensor 8 can sense the wheel at the same time, so a crawler-type two-wheel structure must be used. Figure 6 As shown, the mark 713 is the equivalent length of the railway passenger car wheel 9 at a position 20 mm away from the upper surface of the axle counter sensor 7, and the mark 714 is the equivalent length of the small diameter rotating wheel equivalent diagram at a position 20 mm away from the upper surface of the axle counter sensor 7. The equivalent length of the latter is obviously smaller than the former, which is not enough to make the first proximity sensor 5 and the second proximity sensor 8 sense the wheel at the same time;

[0034] like Figure 7 As shown, a crawler-type two-wheel structure of a main rotating wheel 301 and a slave rotating wheel 304 is adopted, the two wheels drive the crawler 309, and a crawler steel attachment plate 311 is attached to the crawler 309, which can fully meet the operating conditions of the simulated rail passenger car wheels and can realize the portability of the system of the present invention.

[0035] The embodiments of the present invention are described in detail above, but the contents described are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
