Embodiment 1
[0039] As a preferred embodiment of the present invention, it includes a chassis tailstock 5 and a chassis seating frame 6. The chassis tailstock 5 is fixedly installed with a turning support 8, and the chassis tailstock 5 is hinged to the chassis seating frame 6 through the turning support 8 , The chassis tailstock 5 rotates around the hinge center to make the chassis tailstock 5 flip up and down, refer to the instructions attached figure 1 , That is, a schematic diagram of the structure of the present invention after being turned over is given. When the chassis tailstock 5 is turned upwards, the height between the chassis seat frame 6 and the ground can be reduced, thereby making the large-sized chassis carried on the chassis seat frame 6 The device 15 is also lowered in height.
Embodiment 2
[0041] As another preferred embodiment of the present invention, a turning support shaft 3 is provided on the turning support 8, a support seat 9 is fixedly installed on the chassis frame 6 and the turning support shaft 3 penetrates the turning support 8 and the support seat 9. The chassis tailstock 5 is hinged with the chassis seat frame 6 through the turning support shaft 3. When the cargo is loaded on the chassis seat frame 6, the chassis tailstock 5 turns upwards. At this time, the turning support 8 also turns over and supports The seat 9 does not turn over, and the support seat 9 gradually moves downward along with the chassis seat frame 6. Such a structure makes the overturning of the chassis tailstock 5 smoother, and the rest is the same as the first embodiment.
Embodiment 3
[0043] Refer to the instructions attached image 3 As another preferred embodiment of the present invention, a spring torsion accumulator 1 is installed between the supporting seats 9. The spring torsion accumulator 1 includes a pin shaft, a torsion spring 10 sleeved on the pin shaft, and a torsion spring 10 sleeved on the pin shaft. For the outer tube 11 outside the spring 10, both ends of the pin shaft are fixed on the support base 9, one end of the torsion spring 10 is fixed on the pin shaft, and the other end of the torsion spring 10 is fixed on the outer tube 11, under the action of the torsion spring 10 The outer tube 11 is driven to rotate, and the outer tube 11 is connected with the chassis tailstock. There are three spring torsion accumulators 1, and the outer tubes 11 of every two spring torsion accumulators 1 are connected and driven by a link mechanism 2. The turning support 8 and the support base 9 are respectively provided with a marching state locking pin hole 12...
