Frog and turnout
The invention relates to the technical field of railway tracks, in particular to a frog and a turnout. The frog comprises a base, a frog core and a pressing block. A mounting groove is formed in the base, the fork core and the pressing block are both located in the mounting groove, a first rim groove is formed in the base, a second rim groove is formed in the fork core, and the first rim groove is in butt joint with the second rim groove; the two side walls, located on the two sides of the second rim groove, of the fork core abut against the side wall of the mounting groove and the pressing block correspondingly; and the pressing block is detachably connected with the base, and the pressing block is used for locking the fork core. The turnout comprises the frog. According to the frog and the turnout provided by the invention, after the frog core is damaged, only the damaged frog core needs to be independently disassembled and replaced with a new frog core, and other parts can be continuously used; and the pressing block and the frog core are operated above the base during disassembly and assembly, are not easily interfered by other structures and are easier to operate; and the workload consumed by maintenance is small, the maintenance and repair cost is reduced, and the maintenance efficiency is high.
本发明涉及铁路轨道技术领域，具体而言，涉及一种辙叉及道岔。辙叉包括底座、叉心和压块；底座上开设有安装槽，叉心和压块均位于安装槽内，底座上开设有第一轮缘槽，叉心上开设有第二轮缘槽，第一轮缘槽与第二轮缘槽对接；叉心的位于第二轮缘槽两侧的两个侧壁，分别与安装槽的侧壁和压块抵接，压块与底座可拆卸连接，且压块用于锁定所述叉心。道岔包括上述辙叉。本发明提供的辙叉及道岔，在叉心损坏后，只需将损坏的叉心单独拆卸，并更换新的叉心即可，其他部件可继续使用，压块和叉心在拆卸和安装时，均在底座的上方操作，不易被其他结构干涉，更易操作；养护耗费的工作量较小，不但降低了维修和养护成本，而且维护效率较高。
