Abstract
The invention discloses a kind of adjustable for height semi-trailer support, including hydraulic cylinder and support means, the piston rod of hydraulic cylinder is at sweep lower retractable；Support means includes supporting part and base, base is fixed on the lower end of supporting part, supporting part is fixedly connected on piston-rod lower end by connecting plate, is fixed by the first bolt between the first half and the piston rod of connecting plate, is fixed by the second bolt between lower half and the support means of connecting plate.The present invention realizes the automatic lifting of retraction rack by cylinder, decrease the workload of driver in transportation, it is to avoid unnecessary accident, and steadiness also increases.
Description
Technical field
The invention belongs to semitrailer and support field, especially relate to a kind of adjustable for height semi-trailer support.
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 the existing usual steadiness of supporting leg is bad, it is desirable to have improved.
Summary of the invention
In view of this, it is contemplated that propose a kind of adjustable for height semi-trailer support, 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 adjustable for height semi-trailer support, 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 means, described support means includes 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,
Being fixed by the first bolt between the first half and the piston rod of described connecting plate, the lower half of connecting plate fills with supporting
Being fixed by the second bolt between putting, the contact surface area between support means and piston rod is less than the face, upper surface of support means
Long-pending, the first bolt is provided with two at vertical direction, and the second bolt horizontal direction is provided with three, the second bolt in an intermediate position
It is positioned at the underface of the first bolt.
Further, the contact surface between described support means and piston rod is horizontal plane.
Further, the cross-sectional diameter of described support means is more than the cross-sectional diameter of piston rod.
Further, described base is up-narrow and down-wide prismatoid.
Relative to prior art, adjustable for height semi-trailer support of the present invention has the advantage that and passes through cylinder
Realizing the automatic lifting of retraction rack, decrease the workload of driver in transportation, it is to avoid unnecessary accident, steadiness is also
Increase.
