Technical Field

[0001] The utility model relates to the technical field of drawing drawings, in particular to a railway signal drawing auxiliary device. Background Art

[0002] A paper railway signal diagram is a diagram used to represent the display status of railway signal machines. It is of great significance to ensure railway traffic safety. Paper railway signal diagrams usually display different types of signal machines in the form of diagrams, such as entry signals, exit signals, shunting signals, etc. Turnouts are important equipment used to change the direction of train operation on railway lines. Paper railway signal diagrams will show the location, number and possible status of turnouts. Therefore, paper railway signal diagrams mostly use straight lines and circular symbols to indicate the operation status of the railway.

[0003] Currently, engineers rely mainly on traditional rulers (such as T-squares, scales, and angle rulers) and hand-drawing skills to draw railway signal drawings. To ensure the accuracy of the drawings, engineers need to frequently adjust the angle and position of the rulers, which not only increases the complexity of the operation but can also lead to errors introduced by human factors (such as hand fatigue and line of sight errors), thereby affecting the accuracy and efficiency of the drawings. Drawing with rulers for long periods of time places high demands on the engineers' physical strength and endurance, and can easily cause occupational health problems such as arm pain and eye fatigue, which in turn affects work efficiency and drawing quality.
