The invention discloses a ballast clamping prevention device of a middle ballast unloading bottom door, and belongs to the technical field of freight vehicles. The device comprises a driving mechanism, a rotating rod mechanism which is hinged with the driving mechanism, and a first small bottom door and a second small bottom door. When the first small bottom door and the second small bottom door are closed, the first small bottom door and the second small bottom door form closed spaces with a bottom door, a ballast baffle plate device and a ballast flowing plate; the driving mechanism controlsthe first small bottom door and the second small bottom door to be opened or closed by driving the rotating rod mechanism. According to the invention, when a vehicle runs to a turnout and other unsmooth lines, wheels violently collide with a steel rail to cause large vibration of the vehicle body, stone ballasts with small granularity at the bottom door can flow downwards to be blocked into the closed spaces, and the problem that leaked ballasts fall on the turnout to cause derailment of the vehicle and influence the driving safety can be avoided.

    本发明公开了一种中间卸砟底门防夹砟装置,属于货运车辆技术领域,包括驱动机构,还包括:转杆机构,所述转杆机构与所述驱动机构铰接;第一小底门和第二小底门,底门关闭时,所述第一小底门和所述第二小底门分别与底门、挡砟板装置及流砟板构成封闭空间;所述驱动机构通过驱动转杆机构来控制所述第一小底门和所述第二小底门的打开或关闭。通过本发明,当车运行到道岔等不平顺线路发生车轮与钢轨剧烈碰撞使车体震动较大时,使得底门处粒度较小的石砟往下流动能够阻断到封闭空间里,可杜绝发生漏砟掉落在道岔上使车辆脱轨影响行车安全问题。
