As shown in the drawings, the working process of the loading and unloading device of the present invention is shown, and in the initial state, i.e., the transportation state, as shown in fig. 8, the hydraulic cylinder 500 is in the contracted state, the gantry support 400 is also kept in the initial horizontal position, and the secondary platform 200, the tertiary platform 300, and the terminal slope runway 700 are all in the initial folded state.
As shown in fig. 9, the state is a second-third stage platform vertical state, that is, the gantry 400 is driven by the hydraulic cylinder 500 to be in a vertical state, which is equivalent to the middle node position of the whole loading and unloading device in the working process, and the gantry 400 will keep the vertical position for a while after the middle node position.
As shown in fig. 10, the state is a middle state of the two-stage and three-stage platforms, that is, the gantry 400 remains stationary in a vertical state, the first hoisting mechanism 402 on the gantry 400 works, the steel wire rope extends under the action of gravity, the second-stage platform 200 slowly falls down, and the third hoisting mechanism 205 on the second-stage platform 200 works to shorten the steel wire rope 600, so as to drive the three-stage platform 300 to turn over, and further gradually dock with the second-stage platform 200, in this process, the second hoisting mechanism 103 on the first-stage platform 100 works, and the gantry 400 is always pulled, so that the gantry 400 remains stable.
As shown in fig. 11, the docking state of the second-level platform and the third-level platform is completed, that is, the second-level platform 200 is gradually turned from the vertical position to the final position under the action of the first winch 402 on the gantry 400, and meanwhile, the hydraulic legs 204 on the second-level platform 200 are put down to contact with the ground to play a supporting role. In addition, the tertiary platform 300 finally turns to a state of being butted with the secondary platform 200 under the action of the third winch 205 on the secondary platform 200, and the hydraulic support legs 303 on the tertiary platform 300 are also put down and are in contact with the ground to play a supporting role. While the end ramp runway 700 is manually lowered into contact with the ground.
In this state, as shown in fig. 12, which is a final state of the construction of the loading and unloading device for the large-sized cargo railway flatcar, the gantry 400 is retracted by the hydraulic cylinder 500, and gradually moved from the vertical position to the initial position, and the construction of the final loading and unloading device is completed.
The unfolding process of the loading and unloading device for the large-sized cargo railway flat car is that after the car is driven away from the railway flat car, the folding process of the device is the reverse process of the folding, firstly, the gantry support 400 is in a vertical state under the action of the hydraulic cylinder 500, then the secondary platform 200 gradually returns to the vertical position from the final position under the action of the first winch 402 of the gantry support 400, the tertiary platform 300 is also overturned to an initial state under the action of the third winch 205 of the secondary platform 200, the hydraulic support legs 303 are folded, finally, the gantry support 400 also returns to an initial horizontal position under the action of the lifting hydraulic cylinder 500, and the secondary platform 200, the tertiary platform 300 and the tail end slope runway 700 all return to an initial folding state.
The above-listed detailed description is only a specific description of a possible embodiment of the present invention, and they are not intended to limit the scope of the present invention, and equivalent embodiments or modifications made without departing from the technical spirit of the present invention should be included in the scope of the present invention.
