Abstract

The invention discloses an electric lock for locomotives. The electric lock comprises a mechanical part and an electric part and combines mechanical control land electric control. A locomotive door is locked under the electric control. Unpowered unlocking of the door lock is performed in a locomotive. The door can be unlocked manually and mechanically with a triangle key. An electric bolt and an electric pin lower power consumption of the door lock. A first spring of the electric bolt is large in elasticity. Long-term powering requires high power consumption, and a first coil is very hot and burns out easily in long-term operation. The electric pin replaces the first coil of the electric bolt to generate electromagnetic force. A second spring of the electric pin is low in elasticity, low in electromagnetic force, power consumption and current, and suitable for long-term powering. The problem that the existing locomotive door lock is used in the single way causing insecure factors is well solved. In addition, the electric lock is simple in structure, convenient to operate, low in service cost, high in reliable, and well worthy of application.

Description

technical field [0001] The invention belongs to the field of machinery and electronics, in particular to an electronically controlled door lock for a locomotive. Background technique [0002] The existing locomotive doors in our country all use the triangular key to mechanically rotate to unlock and lock. The triangular keys are universal, and any triangular key can open the locomotive door. If the staff has a triangular key, it is possible to open the door of the locomotive, get on the locomotive, and operate the locomotive, causing unexpected accidents; therefore, it is necessary to use an electric key that is not a triangular key to open the door before getting on the locomotive and operating the locomotive. At present, the electric control lock of this class has not yet adopted. Contents of the invention [0003] The purpose of the present invention is to use an electronically controlled door lock for a locomotive, aiming at solving the problem that the existing locom...
