Description
Technical field
This utility model relates to a kind of goods conveying semi-trailer, especially a kind of scalable vehicle frame of pull car.
Background technology
Pull car, also known as retractable vehicle, is the one of the goods special semitrailer of transport.It is generally used to transport log,
Long tubing, long round steel, bridge, the goods of the longer and unsuitable separate transport such as electric pole.The vehicle body of pull car
Long, and there is the vehicle frame of Telescopic, so, its vehicle body can stretch as required, needs
Shi Shenchang, it is simple to transport goods, shortens time unloaded, it is possible to be easy to travel and be not take up too much road money
Source and storehouse place resource.The version of this scalable vehicle frame, the most all uses the case of mutual sheathing
Formula crossbeam, its active box beam casing is contained in fixing box beam, it is possible to flexible, and activity box beam and fixed case
Detent mechanism is set between beam, carries out after determining collapsing length as required locking mutual alignment, this set
Dress sliding structure has following deficiency: the stretching motion between activity box beam and fixing box beam is that slip rubs
Wiping, its frictional force is big, needs bigger pull strength to realize flexible, and it is not very convenient to use.
Particularly, the when that between activity box beam and fixing box beam, coincidence amount being smaller, between them
Gap enlarged relative, activity box beam in addition and the deadweight of fixing box beam, now there will be and stay, the two
Between frictional force increase cause pull difficulty.
Summary of the invention
In order to overcome the above-mentioned deficiency of prior art, this utility model provides a kind of scalable car of pull car
Frame, this scalable vehicle frame can help flexible, the required pull strength minimizing that vehicle body realizes swimmingly, rub
Wiping power reduces, and can improve work efficiency and increase the service life.
This utility model solve its technical problem the technical scheme is that include before take out vehicle frame and rear car
Frame, front taking out has activity box beam on vehicle frame, Rear frame is provided with fixing box beam, and active box beam casing is contained in solid
Determine in box beam, support leg mechanism be set in the lower section of described fixing box beam, support leg mechanism include supporting leg overcoat,
Supporting leg inner sleeve and supporting leg seat, supporting leg seat is fixed on the lower section of fixing box beam, and the upper end of supporting leg overcoat is hinged
On supporting leg seat, that overlaps in supporting leg overcoat and supporting leg offers several pins with matching along its length
Hole, supporting leg overcoat and supporting leg inner sleeve are connected at pin-and-hole by removable pin, logical after support leg mechanism horizontal folding
Cross connector and be placed in the lower section of fixing box beam.
Compared to existing technology, a kind of scalable vehicle frame of pull car of the present utility model, take out car before not only including
Frame and Rear frame, front taking out has activity box beam on vehicle frame, Rear frame is provided with fixing box beam, activity box beam
Being sleeved in fixing box beam, the also lower section in described fixing box beam is provided with support leg mechanism, do not use time
Wait, be placed in the lower section of fixing box beam after support leg mechanism horizontal folding by connector, again due to supporting leg seat
Being integrally fixed at below fixing box beam, the upper end of supporting leg overcoat is hinged on supporting leg seat, at supporting leg overcoat and
Offer with matching along its length several pin-and-holes, supporting leg overcoat and the supporting leg inner sleeve that put in supporting leg are led to
Crossing removable pin to be connected at pin-and-hole, therefore put down by support leg mechanism, support leg mechanism can be around on supporting leg seat
Pin joint rotate, by putting diverse location overlapping position in removable pin is inserted in supporting leg overcoat and supporting leg
Pin-and-hole arranges the length of support leg mechanism, when vehicle frame extends, when activity box beam is from fixing box beam
Reach during stretching out the two coincidence amount smaller time, the support leg mechanism set is forwarded to active box
Beam lopsidedness ground is placed on the ground, along with taking out vehicle frame before continuing traction, owing to Rear frame exists the biggest
Frictional force, Rear frame can follow and slowly move ahead, and support leg mechanism changes angle simultaneously, support leg mechanism
Gradually support activity box beam and the overlapping position of fixing box beam, thus reduce and stay deflection, create
Gap, eliminates frictional force, and then has successfully been retracted to desired location by front taking out vehicle frame；In like manner will prop up
Leg mechanism is placed in fixing box beam lopsidedness and lands, and equally will can front take out vehicle frame indentation fixed case swimmingly
In beam；Visible, the pull strength needed for the realization of whole telescopic process greatly reduces, the flexible friction produced
Power is little, improves work efficiency and extends service life.
