The invention provides a shunting hand wheel locking device. The shunting hand wheel locking device comprises a shell, a guide sleeve, a rod, a limiting block, a spring, a guide sleeve and a brake pin. The shell is fixed on a shunting hand wheel; the guide sleeve is mounted in the shell in an interference manner; the guide sleeve is fixed in the shell; the rod passes through the guide sleeve and is compressed at the bottom of the shell through the spring. The brake pins are symmetrically installed in the rod, and the pressing cap is installed on the rod through the two pins. The method is simple to operate, safe and reliable; during use, the limiting pin is pulled out and rotated by 90 degrees, the pin is put down, and the hand wheel is in a free state and can rotate according to operation; during locking, the limiting pin is pulled out and rotated by 90 degrees, the pin is put down, the hand wheel is in a locking limiting state, and the hand wheel cannot be operated.
本发明提供一种调车手轮锁紧装置,包括壳体、导向套、杆、限位块、弹簧、导向套筒和制动销;所述壳体固定在调车手轮上;所述导向套过盈安装在壳体内;所述导向套筒固定在壳体内;所述杆通过导向套并用弹簧压缩在壳体底部;所述制动销安装在杆内,并对称安装,杆上通过两个销安装有压帽。本发明操作简单,安全可靠;使用时,拔出限位销旋转90°,放下销子,手轮处于自由状态可以按操作旋转;锁紧时,拔出限位销旋转90°,放下销子手轮处于锁紧限位状态,手轮无法操作。
