Opening prevention system for lower side door of general open wagon of railway freight car
The invention discloses a railway wagon general open wagon lower side door anti-opening system which comprises a lower side door plate, a lower side door hinge and a hasp assembly, and further comprises an anti-opening device which is installed on an open wagon side beam and corresponds to the lower end of the lower side door plate in the middle, and the anti-opening device comprises a lock seat, a lock pin and a lock iron. The lock seat is in bilateral symmetry, a left side plate and a right side plate extend forwards to form a lock iron placing groove, the upper portion of the front side of the lock iron inclines outwards to form a structure with a heavy upper portion and a light lower portion, and the upper portion and the lower portion of the lock iron are provided with a lifting lightening hole and a lock iron installing hole respectively. The lock pin comprises a lock pin rotating shaft and a lock pin handle installed at the left end of the lock pin rotating shaft, a plane capable of being attached to the top face of the lock iron installation hole is arranged in the middle of the lock pin rotating shaft, and a limiting protrusion is arranged on the rear side face of the lock iron installation hole. The anti-opening device has the advantages of time saving, labor saving, cost reduction, ingenious design, novel conception, good anti-opening effect, high practical value, great application prospect and the like.
本发明公开了一种铁路货车通用敞车下侧门防开系统，包括下侧门门板、下侧门折页和搭扣组件，还包括安装在敞车侧梁上并居中对应下侧门门板下端的防开装置，防开装置包括锁座、锁销和锁铁，锁座左右对称且左右侧板向前延伸形成锁铁安置槽，锁铁前侧上部向外倾斜形成上重下轻结构，且上下分别设有提拿减重孔和锁铁安装孔，锁铁朝向敞车侧梁的一侧上部设有凸弧结构，锁销包括锁销转轴和安装在锁销转轴左端的锁销手柄，锁销转轴中部设有能与锁铁安装孔顶面贴合的平面，锁铁安装孔的后侧面设有限位凸起，具有省时省力、缩减成本、设计精妙、构思新颖、防开效果好、实用价值高、具有极大的运用前景等优点。
