Below in conjunction with Fig. 7 to Fig. 9, the operating process of lifting appliance is according to an embodiment of the present invention described more specifically.
When the lifting appliance 34 on being installed in military shipping platform car 2 needs lifting cargo, at first control the 4th dynamical element 361 and the 5th dynamical element 362, make win crossbeam 321 and second crossbeam 322 can lateral extent, and then first longeron 311 and second longeron 312 are also stretched out under its induced effect, then controlling the 6th dynamical element makes a pair of front leg strut 351 and a pair of rear support leg 352 stretch out towards ground, because supporting leg supports on the ground, thereby improved the stability of lifting appliance 34.Then Lifting device 34 is launched, controlling first dynamical element 363, second dynamical element 364 and the 3rd dynamical element 365 stretches out it, thereby win bar 341, second bar 342 and the 3rd bar 343 are launched thereupon, to treat that lade ties up on the vertical loading board 344 that is positioned at the 3rd bar 343 tops, prepare to begin lifting.In the process of lifting, further controlling second dynamical element 364, that it is stretched out is more, and Lifting device 34 lifting gradually treats that lade arrives higher position, exceeds the transmission face certain altitude of shipping platform car until it.At last, control first dynamical element 363 and make its withdrawal, treat that lade is placed on the transmission face of shipping platform car thereby make, hoisting process is finally finished.
In particular, referring to Figure 10, when military shipping platform car 2 does not need handling goods, Lifting device 34 of the present invention is in folded state, the ground-surface height of its distance is about 2780mm, and the rear end that makes Lifting device 34 abut against this military shipping platform car 2 also tightly places the top of flexible door frame 31, so the height of vehicle body and structure are compact, at this moment the 6th dynamical element withdrawal, four supporting legs 35 are in contraction state.
Be preferably, because pair of links 37 is hinged on respectively between a pair of rear support leg 352 and second crossbeam, so when a pair of front leg strut 351 of the present invention and a pair of rear support leg 352 are withdrawn under the dynamic action of the 6th dynamical element, a pair of rear support leg 352 is under the application force of coupled pair of links 37, turn to second crossbeam 322, thereby avoided taking up room between a pair of rear support leg 352 and the ground, be convenient to the gradient of military shipping platform car 2, thereby further strengthened the crossing ability of this military shipping platform car 2 by certain altitude.
In addition, in conjunction with Figure 11 and shown in Figure 12, after lifting appliance 34 lifting goods are finished, control the 4th dynamical element 361 and the 5th dynamical element 362 once more, make win crossbeam 321 and 322 withdrawals of second crossbeam, and then drive first longeron 311 and second longeron, 312 inside returns, and near the rear end of transmission platform, thereby make that the structure of this military shipping platform car 2 is more compact.
Should be noted that, when using lifting appliance of the present invention to lift goods, by controlling the 4th dynamical element and the 5th dynamical element, make win crossbeam and second crossbeam can lateral extent, and then drive first longeron and second longeron also stretches out, and be positioned at the outside of the transmission platform of shipping platform car, so just make the shipping platform car utilize transmission platform to transmit goods and utilize two mode of operations of lifting appliance handling goods not disturb mutually, thereby solved shipping platform car of the prior art in the lifting goods, can influence the problem of the transmission of goods on the transmission platform, feasible work efficiency with military shipping platform car of lifting appliance of the present invention improves effectively.
Though should be pointed out that invention has been described by above-mentioned embodiment, yet the present invention also can have other numerous embodiments.Without departing from the spirit and scope of the present invention; those of ordinary skill in the art obviously can make various corresponding changes and distortion to the present invention, but these changes and distortion all should belong in the scope that claims of the present invention and equivalent thereof protect.
