The invention relates to a rail-mounted instant self-locking trailer pump flatcar. The rail-mounted instant self-locking trailer pump flatcar comprises a frame, two front wheels, two mating parts, a linkage assembly, an elastic part and a traction column. Each matching piece is fixedly connected to the corresponding front wheel; the linkage assembly is arranged on the frame and has a rotation stopping state and a driving state, when the linkage assembly is in the rotation stopping state, the linkage assembly is in lap joint with the matching piece to limit rotation of the matching piece, and when the linkage assembly is in the driving state, the linkage assembly and the matching piece separation elastic piece are used for providing acting force enabling the linkage assembly to be converted from the running state to the rotation stopping state, one end of the traction column is rotatably connected to the vehicle frame around a second rotating axis parallel to the first rotating axis, and the linkage assembly is pushed to be converted from the rotation stopping state to the running state in the rotating process. When pump dragging work is carried out, the linkage assembly restores to the rotation stopping state under the action of the elastic piece, so that the front wheels cannot rotate, the situation that the pump dragging flatcar slides on a slope is effectively avoided, and safety is improved.

    本发明涉及一种轨行式即时自锁拖泵平车,包括车架、两个车前轮、两个配合件、联动组件、弹性件及牵引柱。每一配合件固定连接于对应的一车前轮;联动组件设置于车架,且具有止转状态及行车状态,且当联动组件处于止转状态,联动组件与配合件搭接,以限制配合件转动,当联动组件处于行车状态,联动组件与配合件分离弹性件用于提供使联动组件由行车状态转换至止转状态的作用力牵引柱一端绕与第一转动轴线平行的第二转动轴线可转动地连接于车架,且在转动过程中推动联动组件由止转状态转换至行车状态。进行拖泵工作时,联动组件在弹性件的作用下恢复到止转状态,使得车前轮也不可转动,有效地避免了拖泵平车溜坡的情况发生,提高了安全性。
