Description

Technical Field

[0001] The utility model relates to the technical field of axle counter magnetic head installation, in particular to an axle counter magnetic head installation and positioning device. Background Art

[0002] The axle counting system is based on the principle of counting the number of axles. Axle counting heads are set at both ends of the section. The number of train axles entering the idle section of the track is compared with the number of axles leaving the section, and the counting information is transmitted to the corresponding axle counting operation unit in the room. The axle counting operation unit processes the information from the axle counting head and gives an idle / occupied indication.

[0003] The way to count the number of axles is as follows: the two sensor subsystems inside the magnetic head each generate an alternating magnetic field. When the wheel enters this alternating magnetic field, the eddy current of the wheel rim weakens the magnetic field of the wheel sensor. The wheel sensor detects the power consumption in the magnetic field. According to the different current consumption of the two sensor subsystems of the magnetic head, the magnetic head transmits the detected wheel information to the counting module. The counting module processes and calculates the received wheel detection signal. In order to better sense the wheel sensor when the wheel passes, there are requirements for the installation height of the axle counting head.

[0004] At present, the installation method of the axle counter magnetic head is to insert the fixing screw holes at both ends of the magnetic head into the mushroom head screws on the mounting plate, and then put on the fixing nuts. Then one person holds the magnetic head with both hands to adjust the installation height, and the other person uses a tape measure to measure the distance between the upper surface of both ends of the magnetic head and the rail surface. When both the height and the level conditions are met, the bolt and nut assembly is tightened. In this process, two people need to cooperate, the operation is cumbersome, and the accuracy is not easy to be accurately controlled. Utility Model Content
