Limiting type rail fixed car stopping stick and machining method
The invention relates to a limiting type rail fixed car stopping stick which comprises a fixing base, a U-shaped blocking portal frame hinged to the fixing base and a length-adjustable inclined support used for connecting the fixing base with the U-shaped stopping portal frame, and the fixing base is of a rectangular frame structure. The invention further discloses a machining method of the limiting type rail fixed car stopping stick. The limiting type rail fixed car stopping stick has the following beneficial effects that the included angle between the fixing base and the U-shaped blocking portal frame is changed by changing the length of the inclined support, the U-shaped blocking portal frame is in a blocking state in the vertical state, the U-shaped blocking portal frame is in a blocking removing state in the horizontal state, and the U-shaped blocking portal frame can block a mine car from passing and remove blocking.
本发明涉及一种限位式轨道固定挡车棍，包括固定底座、铰接在固定底座上的U型阻挡门架，以及用于连接固定底座与U型阻挡门架的且长度可调节的斜支撑，所述固定底座为矩形框架结构。本发明还公开了一种限位式轨道固定挡车棍的加工方法。本发明具有以下有益效果：通过改变斜支撑的长度，从而改变固定底座与U型阻挡门架之间的夹角，U型阻挡门架竖向状态下为阻挡状态，U型阻挡门架水平状态下为解除阻挡，实现了U型阻挡门架阻挡矿车通过和解除阻挡。
