Tailway-borrowing left-turn line-crossing-preventing equipment and using method
The invention discloses a tailgating left-turn line crossing prevention device and a use method, the structure is provided with a fixed seat, an indicating device and a top cover, the bottom of the indicating device is embedded into the fixed seat and is movably clamped, the top cover is fixedly embedded above the indicating device, the top cover is driven to rotate by a positioning device under lateral thrust and the spherical shape of an abutting ball, and the position of the abutting ball can be changed within a small range; the abutting force with the end face of the grillage is effectively buffered, the blocking force in the clamping installation process of the grillage is reduced due to the fact that the folding frame is hinged, swings and folded, the diameter width of the installation groove is flexibly changed, the toughness of the tough block is matched with the spring steel to have certain rebound force to the abutting ball, the abutting ball is subjected to lateral reverse supporting elastic acting force, and the abutting ball can be better attached to the outer end face of the grillage. And the toughness and the anti-skid property of the abutting ball and the tough block facilitate tough surface contact between the positioning device and the outer end face of the grillage, hard abrasion is prevented, and the problem that installation is not stable easily due to the abrasion condition of the grillage and the installation groove is effectively solved.
本发明公开了一种借道左转防越线设备及使用方法，结构设有固定座、指示装置、顶盖，指示装置底部嵌入固定座内部且活动卡合，顶盖嵌固安装在指示装置上方，通过定位装置受到侧推力，抵球的球状形态，令其转动，且能有小幅度位置变动，有效缓冲与板架端面的相抵力，由折动架发生铰接摆折，灵活变动安装槽的径宽大小，减少板架卡合安装过程的阻碍力，由韧块的韧性配合弹簧钢向抵球有一定的反弹力，令抵球受到侧向的反撑弹作用力，便于其较好的贴合在板架外端面上，且抵球与韧块自身的韧性和防滑性质，利于定位装置与板架外端面呈韧性面接触，防止硬性磨损，有效避免板架与安装槽因磨损情况而容易导致安装不稳的问题。
