Further, in the present embodiment, when wheel and rack 151 engage when, auxiliary support apparatus actuator 23 with it is upper
Guide rail 15 is bonded, and auxiliary support apparatus actuator 23 can be that girder 11 provides support and Forward driving force by upper rail 15,
So that the movement of girder 11 is more stable, smooth.
Further, in this embodiment 13 upper end of the second telescopic outrigger is equipped with for driving that girder 11 moves left and right
Two flexible actuators 131.The inverted arch trestle fixed compared to common left-right position, by the way that the second flexible actuator 131 is arranged
The left-right position of adjustable girder 11, further increases the ease of use of trestle, such as can move left and right concrete tank,
Concrete distributing is avoided to concentrate on inverted arch central region.
As a preferred technical solution, in the present embodiment, two auxiliary support apparatus 2 be located at two second telescopic outriggers 13 it
Between, two second telescopic outriggers 13 can be used as position limiting structure when auxiliary support apparatus 2 is moved forward and backward along lower guideway 14, lifting means
Reliability.Certainly in other embodiments, can also be exchanged.
The conveyer method of the inverted arch trestle of the present embodiment, comprising the following steps:
S1, entrucking: the first telescopic outrigger 22 is shunk before changing trains or buses, and retractable support beam 21, which is shunk, drives two column girders 11 mutually to lean on
Closely, to guarantee that the width of trestle main body 1 is greater than common cargo trailer transportation surface width；Then by inverted arch trestle entrucking in trailer
On, for example, factory when have lifting condition, can directly be lifted；
S2, unload: inverted arch trestle is transported to destination, and retractable support beam 21 stretches out the first telescopic outrigger 22 for making both ends
Being moved to trailer, (first telescopic outrigger 22 in left side is extend out on the left of trailer in other words, and first telescopic outrigger 22 on right side is stretched outside
Out to the right side of trailer), then the first telescopic outrigger 22, which stretches out support telescopic supporting beam 21, makes retractable support beam 21 be higher than trailer
Loading surface, last trailer is outputed to be separated with retractable support beam 21.
Then the conveyer method of the inverted arch trestle utilizes common goods by drawing close two column girders 11 mutually
It transports trailer and realizes transport, using retractable support beam 21, the interoperation of the first telescopic outrigger 22 when unloading, that is, may make shipping to hang
Vehicle is separated from each other with inverted arch trestle, without large-scale crane, reduces dismounting workload when transhipment, convenient, fast.
Further, if when entrucking does not have lifting condition, the method that the present embodiment can also be used, in the present embodiment, step
Suddenly the detailed step of S1 includes:
S1.1, retractable support beam 21 stretch out until the width between the first telescopic outrigger of both ends 22 is greater than trailer loading surface
Width, so that the tail portion of trailer is able to enter between the first telescopic outrigger of both ends 22；
S1.2, the first telescopic outrigger 22 stretch out support telescopic supporting beam 21 until retractable support beam 21 is higher than the loading of trailer
Face, so that the tail portion of trailer is able to enter 21 lower section of retractable support beam；
S1.3, by way of reversing so that the loading surface of trailer tail enters the lower section of retractable support beam 21；
S1.4, the contraction of the first telescopic outrigger 22 make the landing of retractable support beam 21 on the loading surface of trailer, and then first stretches
Contracting supporting leg 22 continues to shrink the loading surface until lower end is higher than trailer；
S1.5, the contraction of retractable support beam 21 make both ends the first telescopic outrigger 22, two girders 11 are close to each other until first stretches
Contracting supporting leg 22, two girders 11 are respectively positioned on above the loading surface of trailer, complete entrucking.Pass through the first telescopic outrigger 22, retractable support
The interoperation of beam 21 can be realized entrucking without large-scale crane, and operate conveniently, quickly.
Although the utility model has been disclosed with preferred embodiment as above, it is not intended to limit the utility model.It is any
Those skilled in the art, in the case where not departing from technical solutions of the utility model range, all using the disclosure above
