Technical field

The present invention relates to the technical fields of bogie arrangement, the specifically auxiliary support apparatus of trailer tune wheel.

Background technique

Trailer refers to by vehicle traction and the vehicle of unpowered driving device itself, by an automobile (lorry or tractor, Fork truck) with the combination of one or one or more trailer, cargo vehicle and towing motorcar are the driving vehicle section of truck combination, referred to as main Vehicle, the slave motor-car section drawn by main vehicle are known as trailer, are the important car types of highway transportation, are to improve warp using truck combination transport The Ji most effective and simple important means of benefit has the advantages such as rapid, motor-driven, flexible, safe；It is convenient to realize section fortune It is defeated.

Existing trailer carries out Auxiliary support to chassis often through single hydraulic jack, since the chassis of trailer is logical It is not often fully horizontal, and traditional hydraulic jack often can not be accurately complete by the chassis of hydraulic jack and trailer Alignment, and then during jacking, damage may be generated to the chassis of trailer.

Summary of the invention

The purpose of the present invention is to provide the auxiliary support apparatus of trailer tune wheel, mentioned above in the background art to solve Problem.

To achieve the above object, the invention provides the following technical scheme:

The auxiliary support apparatus of trailer tune wheel, including at least the support frame and hydraulic jack for having traveling wheel, the support The inside of frame offers circular cavity, and the cavity is internally provided with circular support plate, sets below the support plate It sets that there are four the cylinders of circular array arrangement, is provided with push rod at the top of the cylinder, one end of the push rod is fixed on branch On fagging, the upper face of the support plate is provided with the support rod for being located at same vertical guide with push rod, the top of the support rod It is provided with fixing seat, hydraulic jack is fixed in the fixing seat, the side of the hydraulic jack is provided with oil inlet pipe.

The two sides of the fixing seat are all provided with fixed plate, offer threaded hole in the fixed plate, in the threaded hole It is equipped with screw rod, one end of the screw rod towards hydraulic jack is fixed with fixed block.

As a further solution of the present invention: at least a fixed link, the fixed link are provided with below support frame as described above Bottom end be fixed with traveling wheel, the fixed link is from top to bottom disposed with multiple perforation, the appearance surface cover of the fixed link Equipped with that can be equipped with inserted link on the outside of the fixed ring that fixed link moves along a straight line, the fixed ring, the inserted link passes through solid Determine ring and fixed link and fixed ring are fixed in perforation, two supports of positional symmetry are provided with below the fixed ring Column.

As a further solution of the present invention: the bottom end of the support column is fixed with stabilizer blade.

As a further solution of the present invention: being sealed connection between the oil inlet pipe and hydraulic jack.

Compared with prior art, the beneficial effects of the present invention are: hydraulic thousand can not be made by having abandoned traditional auxiliary support apparatus The perfectly aligned brought defect in chassis on jin top and trailer, the present invention are practical with the setting of fixing seat, support plate and cylinder When operation, on the chassis after be against trailer at the top of hydraulic jack after, according to the actual situation, start the cylinder of corresponding position, So that cylinder is driven support plate inclination, and then make the hydraulic jack top rake in fixing seat and fixing seat, finally makes hydraulic jack Top is perfectly aligned with the chassis of trailer, avoids during jacking, generates damage to the chassis of trailer.
