Description
Technical field
The utility model belongs to semitrailer and supports field, especially relates to a kind of semitrailer lifting landing leg.
Background technology
At present, it mostly is semi-trailer tipping vehicle in the local vehicle being used for transporting bulk goods such as steel mill, harbour.For improving Transportation Efficiency
Rate, reduces the stand-by period, and the unit such as steel mill or harbour to draw semitrailer using dock tractor.Dock tractor is hung on connecting
Trailer, by elevating the saddle of dock tractor, without having shaken supporting leg again, can directly be dragged away by Che Hou.But, bad in road conditions
Place because the limited height of saddle lift, the height leading to supporting leg liftoff is too little, easily touches with the protrusion generation on ground
Hit, break supporting leg.Therefore, need driver to get off when actually used and shake supporting leg.So cause extra work to driver
Amount, and inconvenience of getting on or off the bus easily causes accident.And the usual steadiness of existing supporting leg is bad, it is desirable to have improved.
Content of the invention
In view of this, the utility model is directed to a kind of semitrailer lifting landing leg, can solve the above problems.
For reaching above-mentioned purpose, the technical solution of the utility model is realized in：
A kind of semitrailer lifting landing leg, supporting leg is installed on sweep, including：
Hydraulic cylinder, the cylinder body of described hydraulic cylinder is fixed on sweep upper end, the piston rod of hydraulic cylinder straight down, under sweep
End is flexible；
Support meanss, described support meanss include supporting part and base, and base is fixed on the lower end of supporting part, and supporting part leads to
Cross connecting plate and be fixedly connected on piston-rod lower end.
Fixed by the first bolt between the first half of described connecting plate and piston rod, the lower half of connecting plate fills with supporting
Fixed by the second bolt between putting, the contact surface area between support meanss and piston rod is less than the upper surface face of support meanss
Long-pending, the first bolt is provided with two in vertical direction, and the second bolt horizontal direction is provided with three, the second bolt in an intermediate position
Underface positioned at the first bolt.
Further, the contact surface between described support meanss and piston rod is horizontal plane.
Further, the cross-sectional diameter of described support meanss is more than the cross-sectional diameter of piston rod.
Further, described base is up-narrow and down-wide prismatoid.
With respect to prior art, semitrailer lifting landing leg described in the utility model has the advantage that：Real by cylinder
The automatic lifting of existing retraction rack, decrease the workload of driver in transportation, it is to avoid unnecessary accident, and steadiness also has
Improved.
