Traffic signal lamp for train lane changing

Abstract

The invention relates to the technical field of signal lamp equipment. The invention further discloses a traffic signal lamp for lane changing of the train. The traffic signal lamp comprises a protection box, three supporting columns are fixedly mounted at the bottom of the protection box; the outer surfaces of the three supporting columns are movably connected with supporting pipes in a sleeved mode. The bottom end of the supporting column is fixedly connected with a supporting block located in the supporting pipe, the outer surface of the supporting column is movably sleeved with a damping spring located in the supporting pipe, a connecting column is fixedly installed at the bottom of an inner cavity of the protection box, and the other end of the connecting column is fixedly connected with a signal lamp set. Based on the traffic signal lamp for train lane changing, the vibration force borne by the protection box is transmitted to the damping springs through the supporting columns, the vibration force borne by the protection box in the using process is counteracted through the acting force of the damping springs, and therefore the situation that parts of the signal lamp set in the protection box are loosened and damaged due to the vibration force is avoided, and the practicability of the signal lamp is improved.

Description

technical field [0001] The invention relates to the technical field of signal lamp equipment, in particular to a traffic signal lamp for train lane change. Background technique [0002] A train refers to a vehicle running on a railway track. It is usually composed of multiple carriages. It is one of the modern important means of transportation for human beings. The traffic signal lights for train lane change are an important part of railway command. [0003] Train lane change traffic lights are generally installed next to the train tracks. Due to the heavy weight of the train, there will be large vibrations during the running process. However, the existing traffic lights are mostly fixed to the ground by screws and lack shock absorbing devices. , The long-term impact of the signal light by the vibration force will loosen the internal parts of the signal light, resulting in damage to the signal light and reducing the service life of the signal light. , but most of them only ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a traffic signal light for train lane change, which has the advantages of strong shock resistance and good protection effect, and solves the problem that most of the existing traffic signal lights are fixed to the ground by screws and lack shock absorption. The long-term impact of the signal lamp on the vibration force will cause the internal parts of the signal lamp to loosen, resulting in damage to the signal lamp, reducing the service life of the signal lamp, and most of the existing traffic signal lamps are directly installed outdoors, although there are installation protection Covers, but most of them only partially protect the protective signal lights, and cannot protect all parts of the signal lights, and the protective effect is poor. The signal lights are easily damaged by the wind and sun for a long time, which reduces the practicality of the signal lights.
