When open position, the first movable floor 31 and the second movable floor 32 are located at a predeterminated position below fixed base plate 1111.This
When movable floor 30 is in the closed position, semi-trailer frame has smooth loading end to sample, can be with transferring general cargo；Work as work
When dynamic base plate 30 is in an open position, with reference to the depressed part that Fig. 3 and Fig. 5, movable floor 30 are enclosed with fixed base plate 1111
300 to house the wheel 212 of the second car body carried above which so that the second car body 21 securely is positioned at first
On car body 21.Likewise, identical wheel stopping means can be arranged on the second car body, led with limiting carry above which second
Draw the wheel of headstock so that the second tractor securely is positioned on the second car body, its principle it is similar to the above because
This repeats no more.
Fig. 8 is referred to, the figure is the structural representation of the wheel stopping means for removing vehicle frame, it is to be understood that this
Bright movable floor 30 also can be multipair along the length direction interval setting of vehicle frame, and its position wheel position to be lifted with which is mutually fitted
Should.Each movable floor 31,32 includes Part I 31a, 32a and Part II 31b, the 32b that mutually can close up, preferably,
Part I 31a, 32a and Part II 31b, 32b are equal-sized rectangular plate-like structure.In movable floor 30 in closing
During position, Part I 31a, 32a and Part II 31b, 32b are mutually abutted, and form a joint 311,321 between the two.
Part I 31a, 32a and Part II 31b, 32b are hinged on admittedly by hinge 13 respectively away from one end of joint 311,321
Determine on base plate 1111, a haulage gear 50 is connected with Part I 31a, 32a and Part II 31b, 32b, to drive first
Part 31a, 32 and Part II 31b, 32b mutually close up or separate.
The haulage gear 50 includes the first train 51 and the second train 52,53 and of driving means 55 and the first pull rope group
Second pull rope group 54.First train 51 includes multiple fixed pulleys 510, and the fixed pulley 510 is arranged at car by fixed seat 511
111 bottom of frame is near the two ends of the first movable floor joint 311 and near 31 corresponding corner of the first movable floor.Its
In, the fixed pulley 510 near 311 two ends of joint is vertically arranged, for vertically the first pull rope group 53 of guiding；Turn near this
Fixed pulley 510 at angle is horizontally disposed with, for the first pull rope of horizontal guide group 53.Second train 52 includes multiple fixed pulleys
520, the fixed pulley 520 is arranged at 111 bottom of vehicle frame near the two ends of the second movable floor joint 321 by fixed seat 521
And near 32 corresponding corner of the second movable floor.Wherein, the fixed pulley 520 near 321 two ends of joint vertically sets
Put, for vertically the second pull rope group 54 of guiding；Fixed pulley 520 near the corner is horizontally disposed with, for horizontal guide the
Two pull rope groups 54.
Using such haulage gear, the present invention can drive 53 He of the first pull rope group using driving means 55
Second pull rope group 54.It is preferred that the driving means 55 be an oil cylinder, be arranged on 111 bottom of vehicle frame two movable floors 31,
In 32 interval, its piston end is connected with the first pull rope group 53 and the second pull rope group 54.So, using an oil cylinder with regard to energy
It is enough simultaneously multiple pull rope groups to be carried out putting rope and rope closing, so that oil cylinder drives multiple movable floors to beat via pull rope group simultaneously
Open or close close and each movable floor need not be individually controlled using multiple driving means.Therefore, the structure is realizing movable floor
On the premise of folding, cost is further saved.It is to be appreciated that oil cylinder in other embodiments can also by hoist engine etc. its
He substitutes driving means.
First pull rope group 53 and the second pull rope group 54 are preferably using the steel wire rope with preferable structural strength.First leads
Messenger group includes 531, two second pull ropes 532 of first pull rope and four the 3rd pull ropes 533.First pull rope
531 head end is connected with driving means 55, and tail end is connected with the head end of two second pull ropes 532 by connector 15, four
3rd pull rope 533 is matched two-by-two and is connected with the tail end of two second pull ropes 532 by connector 15 respectively, and four the 3rd are led
The tail end of messenger 533 is matched two-by-two and is connected with the Part I 31a and Part II 31b of the first movable floor 31 respectively.Wherein,
Two second pull ropes 532 bypass fixed pulley 510 of first train 51 at 31 respective corners of the first movable floor respectively,
Four the 3rd pull ropes 533 bypass fixed pulley of first train 51 near 311 two ends of the first movable floor joint respectively
510.Second pull rope group 54 includes the 4th 541, two the 5th pull ropes 542 of pull rope and four the 6th pull ropes 543.
The head end of the 4th pull rope 541 is connected with driving means 55, and tail end passes through the head of connector 15 and two the 5th pull ropes 542
End connection, four the 6th pull ropes 543 are matched two-by-two and are connected with the tail end of two the 5th pull ropes 542 by connector 15 respectively
Connect, the tail end of four the 6th pull ropes 543 matches Part I 32a and Part II respectively with the second movable floor 32 two-by-two
32b connects.Wherein, two the 5th pull ropes 542 bypass second train 52 respectively near 32 respective corners of the second movable floor
The fixed pulley 520 at place, four the 6th pull ropes 543 bypass second train 52 respectively near the second movable floor joint 321
The fixed pulley 520 at two ends.
In order to preferably guide the first pull rope group 53 and the second pull rope group 54,111 bottom of vehicle frame of the present invention also sets
Directive wheel group 56 is equipped with, including the first leading block 561 and the second leading block 562, first leading block 561 and the first round
It is 51 cooperations, the first pull rope 531 of the first pull rope group 53 passes through connector 15 and two after bypassing the first leading block 561
The second pull rope of root 532 connects；Second leading block 562 is coordinated with the second train 52, and the 4th of the second pull rope group 54 the
Pull rope is connected with two the 5th pull ropes 542 by connector 15 behind 541 excessively the second leading block 562.
So, it is placed on the first car body 11 in the second car body 21 or the second tractor 20 is placed on the second car body 21
When, the wheel of the second car body 21 and the second tractor 20 is positioned on the movable floor of corresponding wheel stopping means, activity
Base plate is pressurized so that the first pull rope group and the second pull rope stress, and driving means coordinate release pull rope group, movable floor
Part I and Part II are rotated down and are separated from each other, and the depressed part that movable floor is enclosed with fixed base plate is carried
Wheel bottom it is accommodating wherein, not only reduce loading height but also loading is more consolidated.Needing to load conventional goods
When making semi-trailer frame have smooth loading end, driving means tighten up pull rope group, and pull rope group drives the of movable floor
A part and Part II are rotated up until mutually closing up.When movable floor is located at closed position and open position, first leads
Messenger group and the second pull rope group, will not because stress is in tensioning state and remains the tight fit between train
Loosening is produced because of the upset of movable floor.
When the multipair movable floor of the length direction interval setting along vehicle frame, the wheel stopping means of the present invention still can be by
One driving means drive multipair movable floor synchronous on-off, now need to set up several corresponding leading blocks, its principle with
Above-mentioned introduction similar therefore repeat no more.
The transportation system of the present invention can increase substantially the conevying efficiency of semitrailer, reduce cost of transportation, but above-mentioned loading
Scheme is by way of example only, not exhaustive, on the basis that the present invention is provided, can form different embodiments.To sum up,
The present invention is transported by being used as goods by piggy-back semitrailer and be loaded on piggy-back semitrailer, while energy-saving and emission-reduction and also
Cost of transportation can be reduced, traffic congestion is alleviated, the labor intensity of driver is alleviated, the safety of transport is improve.
