In one embodiment of the present invention, the present invention is applied to a platform-free (yard) loading and unloading working condition of a highway and railway convenient and fast intermodal railway wagon, and as shown in fig. 3, the present invention is a working condition of clockwise rotation of a transit bracket of a highway and railway convenient intermodal railway wagon + platform-free (yard) loading and unloading working condition, and as shown in fig. 4, the present invention is a working condition of counterclockwise rotation of a transit bracket of a highway and railway convenient intermodal railway wagon + platform-free (yard) loading and unloading working condition.
When the rail wagon for road-rail convenient transportation is parked at two sides for loading and unloading without a platform (station yard), the rail wagon selects the transposition direction of the bracket bottom plate 7 in the figure 3 or the figure 4 for loading and unloading according to the relative position of the rail wagon for road vehicles (trailer and container vehicle), and the working principles of the rail wagon and the rail wagon are the same (only the oblique angle arc-shaped hydraulic arm 12 is opened differently). Taking the indexing bracket to rotate clockwise for loading and unloading, namely fig. 3 as an example, the working process is as follows:
step 1: the opening control operation system 4 (human-computer interaction interface + control module + power module) sends an instruction to unfold the two arc hydraulic arms 12 arranged in diagonal angles (the other two arc hydraulic arms in diagonal angles are closed), in order to ensure the integral support in the loading and unloading process, two rotating arm supports 30 are arranged below the arc hydraulic arms 12, after the arc hydraulic arms 12 are unfolded, the two rotating arm supports 30 are opened, and extend towards the ground, until the arc hydraulic arms are landed on the ground to complete the work of supporting the arc hydraulic arms 12, the arc hydraulic arms 12 are provided with sliding grooves with the same radian as the chassis 3, and the pulley assembly 10 on the rotating bracket 7 can conveniently walk along an arc in the sliding grooves in the next transposition.
Step 2: after the process step 1 is completed, the control operation system 4 (human-computer interaction interface + control module + power module) sends an instruction to the rotatable limit blocks 8 at the two sides of the underframe 3, so that the rotatable limit blocks 8 rotate, the limit function of the bracket bottom plate 7 and components thereof is cancelled, then a clockwise rotation transposition instruction is sent to the transposition driving mechanism 13 (the working principle of the transposition driving mechanism is shown as a partial enlarged view I, as shown in figure 7), the transposition driving mechanism 13 drives the bracket bottom plate 7 to rotate clockwise, the lower surface of the bracket bottom plate 7 is provided with a pulley upper hydraulic support mechanism 9 and a pulley component 10 which are fixedly connected along the two ends of the length of the car, at the moment, the pulley upper hydraulic support mechanism 9 is in a locking state, the bracket bottom plate 7 drives the pulley component 10 to firstly walk in an arc-shaped groove on the underframe 3 through the pulley upper hydraulic, the bracket bottom plate 7 drives the pulley assembly 10 to enter the same-radian sliding groove on the arc-shaped hydraulic arm 12 through the pulley-above hydraulic supporting mechanism 9 to continue walking until the pulley assembly 10 touches the position sensor 32 on the arc-shaped hydraulic arm 12, and the position sensor 32 sends a working signal for stopping the indexing driving mechanism 13 to the control operation system 4 (man-machine interaction interface, control module and power module), so that the process is completed.
Step 3: after the transposition step 2 is completed, the control operation system 4 (the human-computer interaction interface, the control module and the power module) continues to send out an opening instruction of the height compensation mechanism 5 on the bracket bottom plate 7, and after the height compensation mechanism 5 is opened, road vehicles (trailers and container vehicles) can run forwards or backwards along the vehicle running pedal 17 on the height compensation mechanism 5, so that the loading and unloading work is completed.
