The invention relates to the technical field of rail engineering, in particular to a safe rail flat car capable of being held and pushed to release hand braking and a usage method, a spring is connected to a brake handle and used for providing elastic force for the brake handle, and the brake handle can be located at the position where a piston of a brake fluid oil tank is kept closed; and when the brake handle overcomes the elastic force to move, the piston of the brake fluid oil tank can be opened, so that the brake fluid oil tank provides driving force for the brake piston cylinder, and thebrake piston cylinder drives the brake chuck to release the brake part of the brake disc. Compared with the prior art. The device has the advantages that the device is simple in structure; a transparent cover is installed on the outer side of a wheel rail to be connected with a brake disc, braking is stable and reliable, a novel brake handle is designed, the working state of a brake is convertedinto a normally-closed state from a normally-open state, accidents caused by the fact that no brake system exists during advancing and parking are avoided, and accidents caused by the fact that workers forget to brake due to negligence can be avoided.
本发明涉及轨道工程技术领域,具体来说是一种手握推行松手制动的安全轨道平车及使用方法,制动把手上连接有弹簧,以用于向制动把手提供弹性力,并使制动把手能处于保持制动液油箱的活塞闭合的位置;而制动把手克服弹性力运动时,能使得制动液油箱的活塞打开,以使制动液油箱向制动活塞缸提供驱动力从而通过制动活塞缸带动制动夹盘松开刹车盘的制动部。本发明同现有技术相比,其优点在于:在轮轨外侧安装透盖进而连接制动盘,制动平稳、可靠,并设计新式制动把手,转换制动器工作状态,使其由常开状态转换为常闭状态,避免行进及驻车时中因无制动系统造成意外事故发生,并能避免工人由于疏忽忘记刹车造成事故的发生。
