The ratchet clamping mechanism is connected with the strip-shaped tooth 11 and is used to adjust the up-and-down movement of the strip-shaped tooth 11 to realize the expansion and contraction of the side edge of the U-shaped clamp 4. The electromagnet 2 is installed at the upper end of the base 6 and is connected with the bottom of the U-shaped clamp 4. The base 6 is placed on the horizontal plane.

[0020] In order to realize the expansion and contraction of the side edge of the U-shaped clamp 4 in the vertical direction, the ratchet clamping mechanism in the utility model comprises a hand wheel 12, a ratchet wheel 13, a pawl 14, a circular gear 15, a shell one 8 and a shell two 7. The hand wheel 12, the ratchet wheel 13 and the circular gear are independently installed on a middle shaft through a snap pin.

The shell two 7 is installed on one side of the shell one 8 and one side edge of the shell two 7 is installed on the side edge of the U-shaped clamp 4. One end of the pawl 14 is installed in abutment with the teeth of the ratchet wheel 13 and the other end of the pawl 14 is fixed on the two side walls of the shell one 8 through the penetrating installation shaft.

The power switch can be turned on by the remote controller 10, and when the signal receiving controller receives the signal, the electromagnet is powered on to generate magnetism throughout the entire passage.

[0027] Working principle: The automatic neutral section passing device of electric locomotive mainly consists of a car-under magnetic cylinder signal receiver and an automatic neutral section passing signal processor. The automatic neutral section passing magnetic cylinder is fixed under the car body on both sides of the locomotive head by bolts. After the locomotive reaches the designated location, the magnetic cylinder signal receiver of the train receives the magnetic signal of the ground buried magnetic cylinder, and the signal processor processes the signal to issue a command to lock the traction system of the train, then disconnects the main circuit breaker, and slides through the non-electric section. After passing through the non-electric section, the magnetic signal of the ground buried magnetic cylinder is received again, and the signal is processed to issue a command to close the main circuit breaker and restore traction.
