Auto-passing phase separation replaceable type ground magnetic sensor for electric locomotive

Abstract

The invention provides an auto-passing phase separation replaceable type ground magnetic sensor for an electric locomotive. The ground magnetic sensor comprises a magnetic steel part and a special sleeper part. The magnetic steel part comprises magnetic steel, the magnetic steel comprises an iron base plate, and the iron base plate is provided with a trapezoidal stainless steel cover cap. A glue bonding magnet special for magnetism is used in the middle of the base plate and located in the trapezoidal cover cap, and the two sides, outside the cover cap, of the base plate are each connected with a stainless steel magnetic wing. Screw holes are formed in the magnetic wings. The special sleeper part comprises a sleeper, a magnetic steel supporting frame and a nut embedded part. The sleeper is provided with a trapezoidal groove, the magnetic steel supporting frame is formed by welding an iron base plate and two stainless steel side plates, and the shape of the magnetic steel supporting frame is matched with that of the trapezoidal groove. The magnetic steel supporting frame is tightly attached to the trapezoidal groove. The auto-passing phase separation replaceable type ground magnetic sensor has the advantages that disassembling is convenient, and replacing efficiency is improved; the magnetic wings are additionally arranged on the two sides of the magnetic steel, so that the sensitivity of an auto-passing phase separation receiving device for the locomotive is improved; the safety and stability of the magnetic steel are guaranteed; the mounting precision and safe stability of the magnetic steel are improved; the safety and stability of the magnetic steel are improved.

Description

technical field [0001] The invention belongs to the technical field of auxiliary equipment for train operation, and in particular relates to a replaceable ground magnetic inductor for automatic phase separation of electric locomotives. Background technique [0002] The ground magnetic sensor for automatic phase separation of electric locomotives is the ground magnetic equipment of the on-board automatic phase separation control system based on maintenance-free ground positioning technology. When the electric locomotive passes, the ground magnetic sensor embedded in the ground automatically sends a corresponding signal to the locomotive, and then automatically completes the electric locomotive power-off and phase separation through the on-board induction receiver and the phase transition control device to ensure the safety and security of the automatic phase separation. reliable. At present, there are mainly two types of electromagnetic sleepers used by domestic electric loc...

AI Technical Summary

Problems solved by technology

Disadvantages: The four screws fastening the stainless steel cover are subject to long-term frequent vibrations of the train during the on-line operation process, and are easy to fall off, causing the stainless steel cover to loosen, resulting in loosening and loss of the magnet, which directly affects the safe operation of the train; in addition, the railway line is large During the tamping operation of the tamping machine, sometimes the four screws are too long or the installation position is not in place, causing the tamping operation of the tamping machine to damage the electromagnetic pillow

Disadvantages: The fixation between the magnetic steel and the sleeper is poor, and the lower threaded screws are easy to loosen, resulting in the displacement, falling off and loss of the magnetic steel, which poses a safety hazard to the safe operation of the locomotive

So far, the replacement of the under-passing electromagnetic pillow still adopts the method of replacing the whole root, and the problems of only replacing the magnetic steel and difficult management of the joint have not been solved. This problem has always plagued the railway engineering and power supply departments.

[0008] In short, the above two methods have many defects such as difficulty in multi-department cooperation and coordination, time-consuming and laborious, waste of resources, and high cost.
