Description
Technical field
The present invention relates to a kind of semi-trailer support, specifically a kind of lifting semitrailer outrigger.Belong to automotive field.
Background technology
At present, superimposed trailer is all the more obvious in the advantage of middle-long distance logistics transportation, has become topmost transport vehicle type.The outside at superimposed trailer front end left and right sides side bar is equipped with movable supporting legs usually, assisting to support superimposed trailer when handling goods or the parking maintenance, and can regulate the height of superimposed trailer according to the actual height of the traction seat of various tractor trucks.These movable supporting legs generally should be contracted in the superimposed trailer driving process, thereby failure-free avoids movable supporting legs to contact with ground, prevents to bring out safety misadventure.
The semi-trailer support general operation of widespread use is loaded down with trivial details on the market now, and the manufacturing cost height is made difficulty, each parts welding, and deflection is big, and alerting ability can't guarantee.
Summary of the invention
At the deficiency that prior art exists, technical matters to be solved by this invention is: provide a kind of lifting semitrailer outrigger, in order to solve problems such as complex structure in the former technology, complex operation and cost height.
For solving the problems of the technologies described above, the technical scheme that the present invention takes is that a kind of lifting semitrailer outrigger comprises outer leg, is sleeved on leg in the lifting of outer leg in-to-in, and the leading screw that connects leg in outer leg and the lifting.The lower end of leg is connected with folding leg in the lifting, and folding leg lower end is a wheeled construction; Leading screw respectively be fixed on lifting in the screw of inboard leg be connected with the bearing seat that is fixed on outer inboard leg; On the leading screw top, bearing seat upper end is connected with captive nut, the bearing seat lower end is connected with the applanation bearing, the applanation bearing is inboard to be connected with leading screw; Outer leg is provided with screw rod, and leg inside, screw rod rear end are connected with screw bearing outside; The screw bearing outside and the clamping of captive nut top outer.
Above-mentioned lifting semitrailer outrigger, described outer leg outer side is connected with, and has the connection steel plate of screw hole.
Above-mentioned lifting semitrailer outrigger, the described screw bearing outside and captive nut top outer are helicitic texture.
Leg is a tubular structure in the above-mentioned lifting semitrailer outrigger, described outer leg and lifting.
Leg and folding leg junction are provided with fixedly lock pin in the above-mentioned lifting semitrailer outrigger, described lifting.
The present invention is by shaking crank, the screw bearing that makes screw rod drive the screw rod rear end rotates, thereby by the screw thread clamping between the screw bearing outside and the captive nut top outer, the drive captive nut rotates, thereby drive the leading screw rotation, thereby the screw that is connected on the interior leg of lifting is moved up and down, drive the interior leg of lifting like this and move up and down; Bonded assembly folding leg in leg lower end does not contact with ground when leg moves up in lifting in the lifting, and at this moment convenient folding leg is upwards turned up, and fixes by fixing lock pin, thereby has simplified the flexible scope of the interior leg of lifting, acts freely, and has saved non-cutting time.Screw of the present invention has adopted high-strength wear-resisting ductile iron and lock pressure technology, and light wear-resisting, intensity is reliable.
Bearing seat is welded on outer inboard leg and leading screw clamping, thereby leading screw is felt relieved; Outer leg outer side is connected with the connection steel plate, can be fixed on the car body by check screw; Be connected applanation bearing on the bearing seat in that leading screw further in the location, is used to bear the axial load of supporting leg, reduce the damage rate of parts, prolong the service life of supporting leg.
The present invention has compact conformation, and cost is low, and welding deformation amount is few, make easy to assembly, the precision height; Adopt the high-strength wear-resisting ductile iron screw, hoisting force is big, light and flexible; Folding leg can be turned up, and is easy to operate.
Description of drawings
Fig. 1 is a kind of structural representation of lifting semitrailer outrigger;
Structural representation when Fig. 2 turns up for the folding leg of a kind of lifting semitrailer outrigger;
Fig. 3 is that a kind of lifting semitrailer outrigger connects the steel plate scheme drawing.
The specific embodiment
Below in conjunction with drawings and the specific embodiments the present invention is described in further details;
A kind of lifting semitrailer outrigger of the present invention comprises outer leg 1, is sleeved on leg 2 in the lifting of outer leg in-to-in, and the leading screw 3 that connects leg 2 in outer leg 1 and the lifting.The lower end of leg 2 is connected with folding leg 4 in the lifting, and folding leg 4 lower ends are wheeled construction; Leading screw 3 respectively be fixed on lifting in the screw 5 of leg 2 inboards be connected with the bearing seat 6 that is fixed on outer leg 1 inboard; On leading screw 3 tops, bearing seat 6 upper ends are connected with captive nut 7, bearing seat 6 lower ends are connected with applanation bearing 8, applanation bearing 8 is inboard to be connected with leading screw 3; Outer leg 1 is provided with screw rod 9, and leg 1 inside, screw rod 9 rear ends are connected with screw bearing 10 outside; Screw bearing 10 outsides and captive nut 7 top outer clampings.Described outer leg 1 outside is connected with, and has the connection steel plate 12 of screw hole 11; Described screw bearing 10 outsides and captive nut 7 top outer are helicitic texture; Leg 2 is a tubular structure in described outer leg 1 and the lifting; Leg 2 and folding leg 4 junctions are provided with fixedly lock pin 13 in the described lifting.
By screw is installed in the screw hole 11 on connecting steel plate 12, semi-trailer support is captiveed joint with car body.When shrinking supporting leg, shake crank, the screw bearing 10 that makes screw rod 9 drive screw rod 9 rear ends rotates, thereby by the screw thread clamping between screw bearing 10 outsides and captive nut 7 top outer, driving captive nut 7 rotates, thereby drive leading screw 3 rotations, thereby the screw 5 that is connected on the interior leg 2 of lifting is moved, drive the interior leg 2 of lifting like this and move; Along with moving up of leg in the lifting 2, folding leg 4 is liftoff, at this moment upwards turns up folding leg 4, and will fold leg 4 by fixing lock pin 13 and fix, treat that leg 2 is contracted at utmost or is retracted to when not influencing the car body operation in the lifting, supporting leg shrinks to be finished.When elongation during supporting leg, will fold leg 4 earlier and put down, shaking crank, thereby making supporting leg reach the purpose of downward elongation, up to folding leg 4 kiss the earths, till car body jack-up.
Above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example, those skilled in the art, and in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
