The working principle of the invention is as follows:
when a railway flat car carries two open-topped containers to enter a tipper rotor, each driving oil cylinder contracts, and the twisting point of the oil cylinder and a pressing and holding frame is dragged downwards through the twisting point of the oil cylinder and the rotor, so that the pressing and holding frame rotates around the twisting point of the tail part of the pressing and holding frame and the rotor, the pressing and holding frames on two sides press the upper part of an outer container corner piece, and the pressing and holding frame in the middle part presses the upper part of the corner piece of the measuring and packaging box in the middle part, thereby completing the pressing and holding action of the open-topped container; because the middle pressing and holding frame is driven by two driving oil cylinders, and the pressing and holding frames on the two sides are driven by one driving oil cylinder, the action of the middle pressing and holding frame is faster than that of the pressing and holding frame on the two sides. At the moment, the middle pressing and holding frame drives the synchronous pore plate to act through the synchronous shaft, so that the outer pressing and holding frames with slow actions at two sides are driven to act, and the synchronous action of all the pressing and holding units is realized.
When the flatcar is not parked accurately and the corner fittings of the outer container are parked to the outer side, the outer pressing and holding unit driven by the single side generates torque between the driving oil cylinder and the pressing point, the outer pressing and holding frame tends to twist, and when the deformation is larger than the gap between the synchronizing shaft and the synchronizing hole, the pressing and holding frame in the middle limits the continuation of the deformation.
Because the size of the synchronous hole is slightly larger than that of the synchronous shaft, each pressing and holding unit still has two support points, and the hyperstatic problem is caused because the support points are added to each pressing and holding unit to generate more than three supports at any position.
The invention has the beneficial effects that: the hyperstatic problem is not generated by a mechanical method, and the synchronous action of each press frame is realized; the structure is simple and convenient, the use is reliable, and the problem of the pressing and holding of the tippler of the railway flat car transportation container tippler is effectively solved.
