[0002] Railway signal refers to a fixed signal on the railway that uses lights of different colors and numbers or arm positions of different colors and shapes to display command lines and shunting orders. According to its functions and characteristics, it can be divided into many types, mainly including color light signal, mechanical signal and positioning signal.

[0003] When installing a railway signal, a concrete block is usually poured at the installation location, and then a hole is drilled on the surface of the concrete block to allow the signal line to pass through the hole. Bolts are then used to pass through the mounting holes of the iron plate at the bottom of the signal to connect to the concrete block for installation. When installing the signal in this way, drilling holes takes extra time, and after the installation is completed, if the position of the signal needs to be adjusted according to actual conditions, the bolts need to be removed one by one and holes need to be drilled again to adjust the position of the signal, resulting in low flexibility when installing the signal.
