Description
Technical field
The invention belongs to semitrailer and support field, especially relate to a kind of detachable semi-trailer supporting leg.
Background technology
At present, it mostly is semi-trailer tipping vehicle at the local vehicle being used for transporting bulk goods such as steel mill, harbour.For improving Transportation Efficiency
Rate, reduces the waiting time, and the unit such as steel mill or harbour uses dock tractor to draw semitrailer.Dock tractor connects upper extension
Che Hou, by elevating the saddle of dock tractor, need not shake supporting leg again, can directly have been dragged away by trailer.But, bad in road conditions
Place because the limited height of saddle lift, the height causing supporting leg liftoff is the least, and easily the outthrust generation with ground is touched
Hit, break supporting leg.Therefore, need driver to get off when actually used and shake supporting leg.So cause extra work to driver
Measure, and inconvenience of getting on or off the bus easily causes accident.And existing semi-trailer support is the most non-dismountable, it has not been convenient to dismounting.
Summary of the invention
In view of this, it is contemplated that propose a kind of detachable semi-trailer supporting leg, the problems referred to above can be solved.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of detachable semi-trailer supporting leg, supporting leg is installed on sweep, it is characterised in that: 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 means, described support means includes a bracer, base and locking device, and a bracer upper end is provided with slot, lives
Stopper rod inserts in slot, on a bracer relative to both sides be provided with screw, locking device can screw to be located in screw, and base is fixed on
Prop up the lower section of bracer；
Described locking device is provided with two, and each locking device includes locking end, screw rod and the handwheel being sequentially connected, locking
End is located in slot, and handwheel is located at outside a bracer, and after handwheel screws screw rod, locking end is close to piston rod.
Further, the upper surface of described bracer is provided with cell body, and a bracer insertion groove body is interior and is welded and fixed.
Further, the longitudinal section of described bracer is isosceles trapezoid.
Further, described locking end is rubber blanket.
Relative to prior art, detachable semi-trailer supporting leg of the present invention is had the advantage that and is realized by cylinder
The automatic lifting of retraction rack, decrease the workload of driver in transportation, it is to avoid unnecessary accident, and conveniently tears open
Dress.
