Passive locking device and double-locking structure for railway vehicle door system
The invention discloses a passive locking device for a railway vehicle door system and a double-locking structure. The passive locking device comprises a sliding block guide rail, and a lead screw is installed on the outer side of the sliding block guide rail; the screw rod is sleeved with a first nut assembly, the first nut assembly comprises a rolling pin, a sliding block, a nut sleeve and a nut, and the nut is made of a non-metal material; the inner wall of the nut is matched with the lead screw. The outer wall of the nut is fixedly sleeved with a nut sleeve. A sliding block is arranged at one end of the nut sleeve, and a rolling pin is arranged at the other end of the nut sleeve; a locking pin limiting stop block is arranged above the sliding block guide rail; the sliding block check block is installed on the locking section, the sliding block guide rail is provided with an opening in the locking section, when the sliding block moves to the locking section, the sliding block retreats from the opening, the rolling pin falls into the inner side of the locking pin limiting check block, and locking is achieved; the sliding block is stopped by the sliding block stop block after retreating, and locking and limiting are achieved. According to the scheme, the lead screw is directly matched with the nut made of the non-metal material, the requirements for the material and hardness of the lead screw are lowered, and lubrication-free in the whole life cycle can be achieved.
本发明公开了一种用于轨道车辆门系统的无源锁闭装置及双锁闭结构，装置包括滑块导轨，滑块导轨外侧安装丝杆；丝杆上套装第一螺母组件，第一螺母组件包括滚动销、滑块、螺母套及螺母，螺母采用非金属材质；螺母内壁与丝杆配合，螺母外壁固定套设螺母套；螺母套一端装滑块，另一端装滚动销，滑块带动第一螺母组件沿滑块导轨移动；滑块导轨上方设置锁闭销限位挡块；还包括装在锁闭段的滑块挡块，滑块导轨在锁闭段设置开口，当滑块移动至锁闭段时从开口退出，滚动销落入锁闭销限位挡块内侧，实现锁闭；滑块退出后被滑块挡块挡住，实现锁闭限位。本方案中丝杆与非金属材质的螺母直接配合，降低了丝杆材料及硬度的要求，可实现全寿命周期免润滑。
