the trolley running mechanism (4) consists of a frame and a second running mechanism, is arranged between the cross beams of the trolley running mechanism (3), is provided with a track, and drives wheels to run along the track; the trolley running mechanism (4) moves within the range of 9m on the beam of the cart running mechanism (3), and the unloading requirements of two lines of train lines with the interval of 8m are met.

9. The rigid anti-swing container unloading equipment system according to claim 1, wherein the electric control system realizes the accurate positioning of the target container (5) and the unmanned operation of lifting, unloading and returning of the container (5) by a reference object arranged on a train line, a scale arranged on a beam of the cart running mechanism (3) and a camera connected with the electric control system and by using a visual recognition system; the vision recognition system employs image processing techniques.

10. A method of operating a rigid anti-swing container tripper system according to any of claims 1 to 9, comprising the steps of:

the method comprises the steps that firstly, a coordinate position of a container (5) on a carriage or a flat car on a train line is located through a visual recognition system, then an electric control system transports a rigid anti-swing unloading mechanism (1) to the position right above the container (5) through controlling a cart running mechanism (3) and a trolley running mechanism (4) according to the coordinate, so that a twist lock on the container hanger (2) is correctly aligned with a lock hole of the container (5), the rigid anti-swing unloading mechanism (1) is controlled to descend, the container hanger (2) connected with a high-strength short lock chain (12) falls, and the twist lock is ensured to be accurately inserted into the lock hole and the lock pin is locked through a guide device arranged on the container hanger (2);

step two, two 8t lifting hoisting mechanisms (8) pull steel wire ropes wound on a lifting pulley block (10) to drive two rigid anti-rocking rods (9) to synchronously lift, so that the container (5) is lifted to a specified height, then the container is conveyed to the upper part of a funnel (7) by a trolley running mechanism (4), and a worker opens a door of the container (5); the visual recognition system can judge the position of the door opening side of the container (5), and controls a rigid anti-rocker (9) positioned on the non-door opening side through an electric control system according to the position, the rigid anti-rocker is driven by a single hoisting mechanism (8) to be independently lifted, the container is lifted for 2m of travel, the inclination angle of the container (5) is 20 degrees at the moment, all grain materials can be poured into a funnel (7), after the pouring is finished, the container (5) is restored to be horizontal, and the door of the container (5) is manually closed; then the electric control system puts the empty container (5) back to the original position according to the original route; the whole operation process of the whole system is controlled by an electric control system with a visual identification and positioning function, and the whole operation process comprises the steps of full-load container (5) lifting and empty container (5) resetting alignment, rigid rocker prevention (9) lifting after the door is opened manually, rigid rocker prevention (9) descending and resetting after the door is closed manually, and all automatic completion.
