According to the structure, the middle part of the lower underframe is provided with the concave bottom, the two ends of the lower underframe are provided with the high bottoms, and the concave bottom and the high bottoms are connected through the inclined bottoms; when the four end upper frame lifting devices control the end upper layer underframe to ascend, the large SUV cars to be transported pass through the high bottom and the inclined bottom to the concave bottom, and some higher large SUV cars can be parked on the concave bottom, so that the space accommodating capacity of the transport vehicle is improved by the concave bottom; the upper end underframe corresponds to a high bottom, so that a large SUV needs to pass through the high bottom and park a car on the high bottom, the angle of the upper end underframe needs to be adjusted, and the space below the upper end underframe is ensured. The angle of the end upper underframe is controlled and adjusted by four end upper frame lifting devices, and the two sides of the front position and the two sides of the rear position of the end upper underframe are symmetrically provided with the end upper frame lifting devices.

An end underframe lifting device for an automobile-container dual-purpose concave bottom transport vehicle comprises a lower underframe 1, an end upper underframe 19 and an end upper frame control device; the middle part of the lower underframe 1 is provided with a concave bottom 5, two ends of the lower underframe are provided with high bottoms 20, and the concave bottom 5 and the high bottoms 20 are connected through inclined bottoms 21; the end upper underframe 19 corresponds to a high bottom 20, four end upper frame control devices are arranged between the high bottom 20 and the end upper underframe 19, and a pair of end upper frame control devices are symmetrically arranged at the front and back positions of the end upper underframe 19; the end shelf control device comprises an end shelf lifting device 22, a multi-stage telescopic sleeve 23 and an end shelf rotating device 24; the multi-stage telescopic sleeve 23 comprises a plurality of support sleeves 25 which are nested in sequence from inside to outside; the supporting sleeve 25 is provided with a plurality of matching holes 26 arranged along the length direction of the supporting sleeve 25; the matching hole 26 is used for inserting a lock pin to lock the length of the multi-stage telescopic sleeve 23; a lifting device 22 for the upper frame is arranged in the multi-stage telescopic sleeve 23; an upper hinging seat 27 is hinged with the upper end of the end upper frame lifting device 22 and the upper end of the innermost supporting sleeve 25 of the multi-stage telescopic sleeve 23, and a lower hinging seat 28 is hinged with the lower end of the end upper frame lifting device 22 and the lower end of the outermost supporting sleeve 25 of the multi-stage telescopic sleeve 23; the upper hinging seat 27 is fixed on one side of the end upper underframe 19, and the lower hinging seat 28 is fixed on one side of the lower underframe 1; the upper frame lifting device 22 is used for controlling the lifting of the end upper layer bottom frame 19; the upper frame rotating device 24 is used for driving the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 to turn over along the length direction of the lower underframe 1. As can be seen from the above structure, the lower underframe 1 is provided with a concave bottom 5 in the middle, and high bottoms 20 are arranged at two ends, and the concave bottom 5 and the high bottoms 20 are connected through an inclined bottom 21; when the four end upper frame lifting devices 22 control the end upper frame 19 to ascend, the large SUV cars to be transported pass through the high bottom 20 and the inclined bottom 21 to the concave bottom 5, and some higher large SUV cars can be parked on the concave bottom 5, so that the space accommodating capacity of the transport vehicle is improved by the concave bottom 5; the end upper underframe 19 corresponds to a high floor 20, so that the large SUV needs to adjust the angle of the end upper underframe 19 to ensure the space below the end upper underframe 19 to pass through the high floor 20 and park the car on the high floor 20. The angle of the end upper underframe 19 is controlled and adjusted by four end upper frame lifting devices 22, and the two sides of the front position and the two sides of the rear position of the end upper underframe 19 are symmetrically provided with the end upper frame lifting devices 22. The end upper underframe 19 has three states when ascending, namely a horizontal working position state, a middle working position state and a full-open working position state, can be mixed with the existing main stream car transport vehicle, improves the applicability of the vehicle, and has higher tilting of the outer end of the end upper underframe 19 compared with the middle working position state; the full open work position is to enable the large SUV to open to the pit bottom 5, and the middle work position is to park some slightly higher cars on the high bottom 20, and the four end upper frame lifting devices 22 can conveniently adjust the angle of the end upper frame 19 and the height of the end upper frame 19.

The off-season vehicles are not idle and cannot occupy the railway, so that the vehicle utilization rate is high, the use cost is reduced, and the transportation capacity of the railway is greatly improved. Because the transport vehicle has no roof and no side wall, the container can not collide when being loaded, and the container can be transported by the whole length of the underframe, thereby improving the transport capacity and the transport efficiency of the transport vehicle. Solves the problems of strong special purpose, low utilization rate and high use cost of the existing railway transportation car.

An end underframe lifting device for an automobile-container dual-purpose concave bottom transport vehicle comprises a lower underframe 1, an end upper underframe 19 and an end upper frame control device; the middle part of the lower underframe 1 is provided with a concave bottom 5, two ends of the lower underframe are provided with high bottoms 20, and the concave bottom 5 and the high bottoms 20 are connected through inclined bottoms 21; the end upper underframe 19 corresponds to a high bottom 20, four end upper frame control devices are arranged between the high bottom 20 and the end upper underframe 19, and a pair of end upper frame control devices are symmetrically arranged at the front and back positions of the end upper underframe 19; the end shelf control device comprises an end shelf lifting device 22, a multi-stage telescopic sleeve 23 and an end shelf rotating device 24; the multi-stage telescopic sleeve 23 comprises a plurality of support sleeves 25 which are nested in sequence from inside to outside; the supporting sleeve 25 is provided with a plurality of matching holes 26 arranged along the length direction of the supporting sleeve 25; the matching hole 26 is used for inserting a lock pin to lock the length of the multi-stage telescopic sleeve 23; a lifting device 22 for the upper frame is arranged in the multi-stage telescopic sleeve 23; an upper hinging seat 27 is hinged with the upper end of the end upper frame lifting device 22 and the upper end of the innermost supporting sleeve 25 of the multi-stage telescopic sleeve 23, and a lower hinging seat 28 is hinged with the lower end of the end upper frame lifting device 22 and the lower end of the outermost supporting sleeve 25 of the multi-stage telescopic sleeve 23; the upper hinging seat 27 is fixed on one side of the end upper underframe 19, and the lower hinging seat 28 is fixed on one side of the lower underframe 1; the upper frame lifting device 22 is used for controlling the lifting of the end upper layer bottom frame 19; the upper frame rotating device 24 is used for driving the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 to turn over along the length direction of the lower underframe 1. As can be seen from the above structure, the lower underframe 1 is provided with a concave bottom 5 in the middle, and high bottoms 20 are arranged at two ends, and the concave bottom 5 and the high bottoms 20 are connected through an inclined bottom 21; when the four end upper frame lifting devices 22 control the end upper frame 19 to ascend, the large SUV cars to be transported pass through the high bottom 20 and the inclined bottom 21 to the concave bottom 5, and some higher large SUV cars can be parked on the concave bottom 5, so that the space accommodating capacity of the transport vehicle is improved by the concave bottom 5; the end upper underframe 19 corresponds to a high floor 20, so that the large SUV needs to adjust the angle of the end upper underframe 19 to ensure the space below the end upper underframe 19 to pass through the high floor 20 and park the car on the high floor 20. The angle of the end upper underframe 19 is controlled and adjusted by four end upper frame lifting devices 22, and the two sides of the front position and the two sides of the rear position of the end upper underframe 19 are symmetrically provided with the end upper frame lifting devices 22. The end upper underframe 19 has three states when ascending, namely a horizontal working position state, a middle working position state and a full-open working position state, can be mixed with the existing main stream car transport vehicle, improves the applicability of the vehicle, and has higher tilting of the outer end of the end upper underframe 19 compared with the middle working position state; the full open work position is to enable the large SUV to open to the pit bottom 5, and the middle work position is to park some slightly higher cars on the high bottom 20, and the four end upper frame lifting devices 22 can conveniently adjust the angle of the end upper frame 19 and the height of the end upper frame 19. After the end upper chassis 19 is lifted to a height by the end upper chassis 22, if the end upper chassis 19 is loaded, the end upper chassis 19 will be adversely affected by long-term loading of the end upper chassis 22, so that the end upper chassis 19 needs to be supported by the multi-stage telescopic sleeve 23 to lock the length of the end upper chassis 22, i.e. the multi-stage telescopic sleeve 23. The multi-stage telescopic sleeve 23 comprises a plurality of support sleeves 25 which are nested in sequence from inside to outside, if three stages are adopted, the multi-stage telescopic sleeve 23 comprises an outer support sleeve 34, a middle support sleeve 35 and an inner support sleeve 36 which are nested in sequence from outside to inside, and each support sleeve 25 is provided with a plurality of matching holes 26 arranged along the length direction of the support sleeve 25; the inner side of the top and the outer side of the bottom of each support sleeve 25 are provided with limiting parts, so that when the length of the support sleeve 25 positioned inside is insufficient along with the ascending of the bottom frame 19 at the upper layer of the end part, the outer support sleeve 25 is pulled to move upwards, the length of the multi-stage telescopic sleeve 23 is finally adjustable, and when the multi-stage telescopic sleeve 23 needs to be locked, only a lock pin is needed to be inserted into a corresponding aligned matching hole 26 to lock the length of the multi-stage telescopic sleeve 23, namely, each support sleeve 25 cannot move mutually; the lock pin can adopt a self-lock pin; since the multi-stage telescopic sleeve 23 and the overhead lifting device 22 have a length so that the end upper underframe 19 cannot vertically fall onto the lower underframe 1, the overhead rotating device 24 is required to drive the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 to turn over along the length direction of the lower underframe 1, so that the end upper underframe 19 can be supported on the lower underframe 1 after being offset along the length direction. The device ensures that the transport vehicle not only can be used for double-layer transport of the trolley, but also can park large trucks or containers when the end upper underframe 19 is supported on the lower underframe 1, so that the transport vehicle can transport other cargoes, and the return of empty vehicles is avoided. The off-season vehicles are not idle and cannot occupy the railway, so that the vehicle utilization rate is high, the use cost is reduced, and the transportation capacity of the railway is greatly improved. Because the transport vehicle has no roof and no side wall, the container can not collide when being loaded, and the container can be transported by the whole length of the underframe, thereby improving the transport capacity and the transport efficiency of the transport vehicle. Solves the problems of strong special purpose, low utilization rate and high use cost of the existing railway transportation car. No obstacle is present on the end upper underframe 19 all the time to prevent the container from being loaded, and the multi-type intermodal transportation capability is provided, so that the transportation efficiency is high and the transportation cost is low. The concave bottom 5 is a concave part in the middle of the lower underframe 1 and comprises a concave bottom surface and two side walls connected with the bottom surface. The end upper underframe 19 adopts a plate girder type structure.
The end upper frame rotating device 24 is a telescopic cylinder or a telescopic hydraulic cylinder; the telescopic end of the upper frame rotating device 24 is hinged with a support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23, and the end of the cylinder barrel is hinged with one side of the lower bottom frame 1. As can be seen from the above configuration, the upper end frame rotating device 24 is a telescopic cylinder or a telescopic hydraulic cylinder, and is simple to control, and the multistage telescopic sleeve 23 and the upper end frame lifting device 22 are controlled to rotate by telescopic operation, so that the upper end frame 19 can be supported on the lower frame 1 after being offset in the longitudinal direction. The upper end frame rotating device 24 can also be other power mechanisms with matched gears and racks.
The end upper frame lifting device 22 is a telescopic cylinder or a telescopic hydraulic cylinder. As can be seen from the above structure, the end upper frame lifting device 22 is a telescopic cylinder or a telescopic hydraulic cylinder, the control is simple, the height and angle of the end upper frame 19 are controlled by telescopic operation, and the end upper frame lifting device 22 is also conveniently built in the multi-stage telescopic sleeve 23. The end bracket lifting device 22 can also be other power mechanisms matched with a gear and a rack.
The end shelf control device further comprises a stabilizing rod 29; one end of the stabilizing rod 29 is hinged with the lower underframe 1, and the other end of the stabilizing rod is detachably connected with a third hole lug 30 arranged on the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23; the stabilizing rod 29 is used for forming a stabilizing triangle together with the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 and the lower underframe 1. As can be seen from the above structure, since the multi-stage telescopic sleeve 23 can be turned over, after the position of the multi-stage telescopic sleeve 23 is determined, locking is required to avoid the end-on-frame rotating device 24 from being in a working state all the time; the stabilizing rod 29 can be a pull rod with an adaptive length or an adjustable telescopic threaded rod, and has the advantages of simple structure and low manufacturing cost. One end of the stabilizing rod 29 is hinged with the lower underframe 1, and the other end of the stabilizing rod 29 can be connected with a third hole lug 30 arranged on the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 through a lock pin, namely the lock pin is inserted into a through hole of the third hole lug 30 and a through hole corresponding to the stabilizing rod 29 at the end; the stabilizing rod 29 is used for forming a stabilizing triangle together with the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23 and the lower underframe 1. When the multi-stage telescopic sleeve 23 needs to rotate, the lock pin is pulled out.

The concave bottom 5 is a concave part in the middle of the lower underframe 1 and comprises a concave bottom surface and two side walls connected with the bottom surface. The end upper underframe 19 adopts a plate girder type structure.
The end upper frame rotating device 24 is a telescopic cylinder or a telescopic hydraulic cylinder; the telescopic end of the upper frame rotating device 24 is hinged with a support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23, and the end of the cylinder barrel is hinged with one side of the lower bottom frame 1.

When the multi-stage telescopic sleeve 23 needs to rotate, the lock pin is pulled out.
Both sides of the end upper underframe 19 are provided with upper movable bars 31; the upper end shelf movable rail 31 is lockable in the upturned position and stowable in the downturned position. According to the structure, when a person operates, the end upper underframe 19 is put in the upturned position to be locked, so that the protection function is realized; the end upper underframe 19 is connected to one side of the end upper underframe 19 through a hinge seat, so that the end upper underframe 19 can be turned over, a matched through hole is drilled in the end upper underframe 19 and the hinge seat, and a lock pin is inserted to lock the end upper underframe 19 at an upturned position; when the end upper underframe 19 needs to be stored in the downward turning position, the end upper underframe 19 is turned to be stored in the approximately horizontal position, so that the container is prevented from being damaged when being loaded.
One end of the end upper underframe 19 is hinged with a cab apron 32, and the other end is hinged with an end upper auxiliary underframe 33; the end upper auxiliary chassis 33 is used for connecting the middle upper chassis 2 arranged above the concave bottom 5 when the end upper chassis 19 is in a rising state, and the end upper auxiliary chassis 33 can be folded down and stored below the middle upper chassis 2 when the end upper chassis 19 is in a descending state.

As can be seen from the above construction, there is thus a large space between the upper floor 20 and the end upper underframe 19 for accommodating the car, since the car is also high in the middle and low on both sides.
The end-on-shelf control device further comprises a transverse stabilizer bar; one end of the transverse stabilizer bar is connected with the end upper underframe 19, and the other end of the transverse stabilizer bar is connected with the support sleeve 25 at the outermost part of the multi-stage telescopic sleeve 23; the transverse stabilizer bar is used for forming a stable triangle together with the multistage telescopic sleeve 23 and the end upper underframe 19; the stabilizer bar is detachable.
