Embodiment 1

[0023] Embodiment one: image 3 , Figure 4 and Figure 5 Shown is the first embodiment of the control circuit of the present invention used on a locomotive. Add two moving contacts on the front pull position A of the SK direction handle of the controller: move contact one 1' and move contact two 3', and add two on the back pull position B of the SK direction handle of the controller Moving contacts: moving contact 3 2' and moving contact 4 4', corresponding to moving contact 1 1', there is a front pull static contact 1, corresponding to moving contact 2 3', there is a front pull static contact Point two 3, when the locomotive is moving forward, the driver controller is in the "front pull" position, at this time, the moving contact 1' is connected with the static contact 1 of the front pull position, and the moving contact 2 3' is connected with the static contact point 1 of the front pull position. The contacts 2 and 3 are connected, and between the static contact 2 3 of t...

Embodiment 2

[0025]Embodiment 2: Three moving contacts are added on the front pull position A of the controller SK direction handle: moving contact one 1', moving contact two 3' and moving contact five 5', on the controller SK Three moving contacts are added on the rear pull position B of the direction handle: three 2', four 4' and six 6', corresponding to the one 1' static contact Point 1 1, corresponding to the moving contact 2 3' and the moving contact 5 5', there are two front-drawing static contacts, which are respectively the front-drawing static contact 2 3 and the front-drawing static contact 2 5, corresponding to The moving contact 2 3' is equipped with the static contact 1 3 of the back pulling position, and the corresponding moving contact 2 4' and the moving contact 6 6' are equipped with the static contact 2 4 of the back pulling position and the static contact 2 6 of the rear pulling position , when the locomotive is moving forward, the driver controller is in the "front pull...

Abstract

The invention discloses an automatic reversing control circuit for locomotive headlamps. A first movable contact and a second movable contact are arranged at a front traction position of a driver controller directional lever, a third movable contact and a fourth movable contact are arranged at a rear traction position of the driver controller directional lever, a first front traction position fixed contact is arranged corresponding to the first movable contact, a second front traction position fixed contact is arranged corresponding to the second movable contact and connected with a front end headlamp contactor coil, and a front end headlamp contactor contact is connected with the locomotive front end headlamp. A first rear traction position fixed contact is arranged corresponding to the third movable contact, a second rear traction position fixed contact is arranged corresponding to the fourth movable contact and connected with a rear end headlamp contactor, and the rear end headlamp contactor is connected with the locomotive rear end headlamp. The automatic reversing control circuit has the advantages that additional operation of a trainman on the headlamps is omitted; the labor intensity of the trainman working at night is relieved, driving operation is more convenient and rapider, and meanwhile severe traffic accidents caused by the fact that the trainman fails to turn on the headlamps in time are avoided.

Description

technical field [0001] The invention relates to a control circuit, in particular to a control circuit for automatic reversing of headlights of a locomotive, which belongs to the field of locomotives. Background technique [0002] When the locomotive is running at night, the flight attendant needs to turn on the headlight on the side of the locomotive running direction. Especially for shunting locomotives, their own working characteristics determine that they need frequent reversing. Only one night operation process requires at least dozens or even hundreds of times of reversing. A hundred times. [0003] The existing locomotive headlight control scheme is to connect a 10,000-turn switch in series in the headlight control circuit to realize the conversion control of the front end and rear end headlights of the locomotive. When the locomotive is moving forward, the flight attendant will turn the 10,000-turn switch to the "front-end" position. At this time, the headlights at ...
