Example 1:
as shown in fig. 1, embodiment 1 of the present invention provides a movable ferry plate assembly for a germany double-deck vehicle for automobile transportation, which mainly comprises seven parts, namely a first movable ferry plate 2, a second movable ferry plate 3, a first folding seat 4, a second folding seat 5, a first locking device 6, a second locking device 9 and a fastener, as shown in fig. 1 and fig. 2.
The first movable ferry plate 2 and the second movable ferry plate 3 both adopt a plate-beam type welding structure form. One side of the first movable ferry plate 2 is hinged with three first folding seats 4 assembled and welded on the end cross beam of the upper-layer base frame 1 through first folding pin shafts 18, the other side of the first movable ferry plate 2 is provided with three second folding seats 5, and the second movable ferry plate 3 is hinged with the three second folding seats 5 through second folding pin shafts 20.
The first locking devices 6 comprise two devices which are respectively connected with the two ends of the first movable ferry plate 2 through pin shafts; a lock seat pin shaft 8 corresponding to the first locking device is arranged on the upper-layer underframe 1, and the first locking device is connected with the lock seat through a pin shaft;
the second locking devices 9 comprise two and are respectively connected with the two ends of the second movable ferry plate 3 through pin shafts; the locking plate 10 corresponding to the first locking device is arranged on the first movable cab apron 2, and the second locking device is connected with the locking plate 10 through a locking plate pin shaft 11;
furthermore, handrails 12 are further arranged at two ends of the first movable ferry plate 2.
Further, two ends of the first movable ferry plate 2 are provided with first rib plates 13, and the first locking device 6 is connected with the first rib plates 13 and the first movable ferry plate 2 through first rib plate pin shafts 14;
furthermore, two ends of the second movable ferry plate 3 are provided with second rib plates 15, and the second locking device 9 is connected with the second rib plates 15 and the second movable ferry plate 3 through second rib plate pin shafts 16.
The movable cab apron assembly has the functions or requirements of connecting an upper loading surface and a loading platform, meeting the maximum loading length of the upper loading surface, meeting the compression space and the safe distance between vehicles, not occupying the space of a shunting crew and the parking rectangular space, and realizing two-stage lifting and falling.
The movable ferry plate assembly can be arranged into three working positions as shown in figures 4-6: a loading station, a single-deck shipping station, and a double-deck shipping station. The loading position is used for connection transition of a train end vehicle and the loading platform, so that the vehicle can smoothly enter an upper loading surface, and meanwhile, a gap between the vehicles is connected, and the vehicle can smoothly pass through when being loaded; the double-layer transportation position requires the movable cab apron to be formed to fully utilize the clearance between vehicles, and the maximum length of the upper loading surface is realized; the single-layer transportation position requires that the movable cab apron composition does not interfere with a shunting personnel space, a Berille rectangular space (shown in figure 3) and a lower layer movable cab apron.
The movable cab apron assembly can realize three working positions, namely a loading position, a double-layer transportation position and a single-layer transportation position in sequence by operating the second locking device 9 and the handrail 12 as shown in figures 4-6.
Loading position: the upper planes of the first movable ferry plate 2, the second movable ferry plate 3 and the upper loading surface 1 are basically coplanar;
double-layer transportation positions: the upper planes of the first movable ferry plate 2 and the second movable ferry plate 3 are vertical to each other, and the upper plane of the first movable ferry plate 2 is substantially coplanar with the upper loading surface 1;
single-layer transportation position: the upper planes of the first movable ferry plate 2 and the second movable ferry plate 3 are coplanar and are vertical to the upper loading surface 1.
The front end of the first locking device 6 is hinged with the first rib plate 13 through a first rib plate pin shaft 14, and the rear end of the concave sliding groove of the first locking device 6 is matched with the lock seat 7 welded on the side beam through a lock seat pin shaft 8 to perform specified actions, namely the locking and unlocking processes are realized. Similarly, the second locking device 9 can also carry out the locking and unlocking process.
The first locking device 6 can always keep the state under the premise of non-manual operation due to self gravity when in the locking state, the locking stability is ensured, the unlocking state can be achieved only when the first locking device is manually lifted upwards, then the first movable cab apron 2 can be lifted or laid down, and the first locking device 6 can automatically enter the locking state after the operation is in place. The functional properties of the second locking means 9 are the same as those of the first locking means 6.
The second movable ferry plate 3 is light in weight, so the second locking device 9 also serves as a handrail for lifting or lowering the second movable ferry plate 3, thereby avoiding a separate handrail on the second movable ferry plate 3.
When the special vehicle for the German double-layer transport vehicle adopts double-layer transport, the movable cab apron components positioned at the two ends of the upper layer underframe of the vehicle can be partially lifted, thereby not only ensuring the loading length of the upper layer loading surface as long as possible, but also meeting the compression space and the safety distance between the vehicles when the train turns.
When the single-layer transportation position is formed by the movable cab apron, the space of a shunting crew, the space of a Berille rectangle and the space of the lower movable cab apron are not occupied.
When the special vehicle for the German double-deck transport vehicle adopts single-deck transport, the upper-deck chassis is wholly descended, the movable ferry plate composition can be completely lifted and kept stable, so that the requirements of UIC 535-2 appendix C on the space of a shunting crew and the space of a Berille rectangle are met, and the movable space of the lower-deck movable ferry plate is prevented from being invaded.
When the double-layer transportation position is formed by the movable cab apron, the vertical size direction does not occupy the space of a shunting worker, and the clear height of the lower-layer loading surface is ensured.
When the special vehicle for the German double-layer transport vehicle adopts double-layer transport, the overall dimension formed by the movable cab apron meets the requirements on the space of a shunting crew in UIC 535-2 appendix C, and the vertical loading space requirement of the lower loading surface, namely the clear height of the lower loading surface is met. Meanwhile, the movable cab apron is formed under the premise of specified overall dimension, and the structural strength of the movable cab apron meets the use requirements under various working conditions.
The movable cab apron has high coaxiality of left and right side structures, light weight and high strength, and has the requirements of operability and the like when being laid down and lifted. The movable cab apron is formed into a bilateral symmetry structure, the design size is completely symmetrical, and higher coaxiality can be ensured after installation and debugging. The operating force of the movable cab apron is designed within the range of 25kg, and good supporting effect and stability can be kept when an automobile with the net weight of 3.2t passes through the movable cab apron at the speed of 25km/h, and any bouncing and shifting do not occur.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
