XDH—Ⅰ型半圆式田径分道画线器的主体,主要是由横梁、标志杆和控制调节杆组成,运用数学和机械原理,通过调节控制调节杆,控制标志杆与横梁之间的夹角,以跑道内突沿外沿(或标志线外沿)为基准线,使标志杆沿之运动,获得横梁在跑道直段和弯道上的画线.它的使用将可降低工作强度、提高工效,适用于半圆式田径场的分道画线;既可一次性地画出跑道的各分道线,又能达到规则要求.本文着重介绍了其设计原理、使用方法和适用范围.
The main body of XDH-Ⅰ semicircle track dividing line drawing device mainly consists of crossbeam, signpost and control adjusting lever. By using mathematical and mechanical principle, the angle between signpost and crossbeam is controlled by adjusting and controlling the adjusting lever , With the outer edge of the runway along the outer edge (or mark the outer edge of the line) as the base line, so that the mark along the pole movement to get the beam in the runway straight segments and corners of the drawing line. It will reduce the use of work intensity and improve ergonomics , Suitable for semi-circular track and field laneway drawing; can draw out the runway of the laneway once, but also to meet the regulatory requirements.This article focuses on the design principles, methods of use and scope of application.
