Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that these embodiments are only used for
Illustrate the present invention rather than limitation the scope of the present invention, after the present invention has been read, those skilled in the art are to the present invention
The modifications of the various equivalent form of values fall within the application appended claims limited range.
As shown in Figure 1 to Figure 3, a kind of height-adjustable semitrailer gooseneck, including gooseneck bracket 2, a pair it is symmetrically arranged
Gooseneck beam 5 and a pair of symmetrically arranged telescopic oil cylinders 4.One end of gooseneck bracket 2 and vehicle frame 1 is affixed, and the other end connection of vehicle frame 1 is used
In the docking platform 3 with traction saddle docking.
The downside of docking platform 3 is provided with for the towing pin 12 with traction saddle docking.Docking platform 3 is by being symmetrical arranged
Two connection units be connected with vehicle frame 1.Connection unit includes connecting rod 6, connecting rod 7 and pull bar 8, wherein the one end of connecting rod 6 with
Docking platform 3 is be hinged, and the other end is hinged with the one end of connecting rod 7, and one end of the other end and pull bar 8 of connecting rod 7 is hinged, pull bar 8 it is another
One end is hinged with vehicle frame.
Connecting cross beam 13 is provided between a pair of gooseneck beams 5, ensures both linkages.Gooseneck beam 5 is double-decker, bilayer knot
Stiffening plate 11 is provided among structure.The one end of gooseneck beam 5 and gooseneck bracket 2 are be hinged, the other end by the support 9 on docking platform 3 with
Docking platform 3 is be hinged, and gooseneck beam 5 is also be hinged with connecting rod 6 and grease nipple 10 is provided with hinged place.
A pair of symmetrically arranged telescopic oil cylinders 4, one end is be hinged with vehicle frame 1, and the other end is be hinged with connecting cross beam 13.
The specific work process of the present invention is as follows：
As shown in Figure 1 to Figure 3, when a pair of telescopic ends of telescopic oil cylinder 4 stretch out, power that connecting cross beam 13 is acted on downwards, together
When control gooseneck beam 5 around with the pin joint rotate counterclockwise of gooseneck bracket 2.
Gooseneck beam 5 acts on active force on docking platform 3 and connecting rod 7 simultaneously.Docking platform 3 is acted on down by active force
Drop, while connecting rod 7 does clockwise movement around the pin joint with gooseneck beam 5.
Now, forces are applied to do counterclockwise movement around the pin joint with docking platform 3 for connecting rod 6, and pull bar 8 can be around
And do counterclockwise movement with the pin joint of vehicle frame 1, total keeps stable, and docking platform 3 is connected with the loading platform of gooseneck bracket 2
Between difference in height increase.
When the telescopic end of telescopic oil cylinder 4 shrinks, docking platform 3 can rise on the contrary, by mutual between each articulated mounting
Effect, structure remained stable, the difference in height between docking platform 3 and the loading platform junction of gooseneck bracket 2 reduce.
In the specific implementation, generally first gooseneck bracket 2 is connected with loading platform, then by adjusting telescopic oil cylinder 4, puts down docking
Platform 3 is steady with the traction saddle of tractor, is neatly connected.
In addition, after connection, actual loading, unloading and during by limit for height road can also pass through the flexible oil of regulation
The flexible situation of cylinder 4, to adjust the height of vehicle frame 1 and gooseneck bracket 2, so as to coordinate the loading platform arrangement for adjusting height of semitrailer
The overall height of semitrailer is controlled, it is convenient to freight, unload and pass through limit for height road.
When the loading platform of semitrailer does not have arrangement for adjusting height, can also by adjusting the flexible situation of telescopic oil cylinder 4,
To adjust the height of vehicle frame 1 and gooseneck bracket 2, moved after making loading platform center of gravity, facilitate loading, unloading goods.
