Electrical adjusting device for locomotive head lamp

Abstract

The invention relates to the technical field of railway locomotive head lamps, in particular to an electrical adjusting device for a locomotive head lamp, which can overcome the problems of poor focusing, difficult adjustment of irradiating distance, low reliability and poor maintainability of the existing locomotive head lamp. The electrical adjusting device for the locomotive head lamp comprises a head lamp base which comprises a head lamp bottom plate and a supporting arm for a reflector assembly, and the reflector assembly which comprises a reflector bracket and a reflector fronting boss,a linear guide rail is erected and arranged above the reflector fronting boss and is provided with a lamp base slider, and a lamp is arranged on the lamp base slider; a first decelerating motor and asecond decelerating motor are arranged below the reflector fronting boss, the first decelerating motor is articulated with the lamp base slider by a first crank and a first connecting rod, and the second decelerating motor is articulated with the head lamp base by a second crank and a second connecting rod. The electrical adjusting device for the locomotive head lamp has the advantages of simple structure, convenient operation, easy and convenient maintenance, low cost and the like, and the device solves problems which remain undecided for a long time in the railway locomotive field.

Description

technical field [0001] The invention relates to the technical field of railway locomotive headlights, in particular to an electric adjustment device for locomotive headlights. Background technique [0002] Known, when train is running at night and in tunnel, locomotive headlight directly influences locomotive steward to observe the line situation ahead, and locomotive headlight plays an important role to train safe operation. [0003] At present, a common motorcycle headlight consists of a headlight base (including a headlight base plate and a reflector assembly support arm), a reflector assembly (including a reflector bracket with a reflector and a front boss of the reflector), a bulb and its power supply. The trigger circuit is composed, and its adjustment structure adopts a semi-fixed method, which is manually adjusted with bolts / screws. The current domestic main type electric locomotives are Shaoshan series electric locomotives. The headlights installed on them can be r...

AI Technical Summary

Problems solved by technology

[0012] The present invention overcomes the problems of poor focus of the headlights and difficulty in adjustment when the irradiation distance is too far or too short in the existing common locomotive headlight adjustment device, and overcomes the problems of low reliability, high cost and poor maintainability in the prior art , to provide a highly reliable, low-cost and easy-to-maintain motorized adjustment device for headlights of locomotives
