Description
Technical field
The invention belongs to crane technical fields, and in particular to a kind of adjustable wheel assembly applied to gantry crane trolley.
Background technique
With the continuous development of port traffic industry, large-scale Quayside container lifting is also more more and more universal, portal crane (bank
Bridge) castor it is increasing.In order to meet the working efficiency of harbour handling, gantry crane trolley along track travel speed increasingly
Fastly, 240m/min-350m/min can be reached.Main component of the gantry crane trolley as loading and unloading container, traveling comfort are straight
Connect the working efficiency for influencing crane.In order to guarantee the stationarity of gantry crane trolley travelling, wheel build-up member needs in trolley
Meet higher required precision.
In the required precision of car wheel assembly, the angle and wheel center line of car wheel center line and horizontal plane are same
Angular deviation (i.e. the vertical missing of wheel shaft centre line and direction of advance) between its theoretical centerline in the horizontal plane has sternly
Lattice regulation.
It has been recognised by the inventors that in existing gantry crane car wheel assembling structure, gantry crane car wheel axis and horizontal plane and preceding
Angle into direction carries out adjustment when leaving the factory, it has not been convenient to which user voluntarily adjusts.Gantry crane trolley after a period of use, rail
Road and gantry crane trolley are likely to occur certain deformation, need user voluntarily adjust between the precision and two wheels of trolley away from
From existing regulative mode is complex, needs to waste more time.
Summary of the invention
It is a kind of applied to the adjustable of gantry crane trolley the purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, providing
Wheel assembly can facilitate manufacturer and user to adjust the angle of wheel center line and horizontal plane and trolley direction of advance,
The distance between two wheels can be adjusted.
To achieve the above object, the present invention adopts the following technical solutions: a kind of adjustable wheel applied to gantry crane trolley
Assembly, including wheel, axletree and vehicle frame, one end of the axletree connect with vehicle wheel rotation, the other end pass through rear support and

Itself and horizontal plane and the vertical missing with gantry crane trolley direction of advance can be changed；After axletree rotation, pass through
Fixed rear support and vehicle frame can be realized the fixation of axletree, keep the assembly precision of axletree, wheel and vehicle frame.
The fore bearing support is bonded close to the vertical end face of wheel with a vertical end face of vehicle frame, fore bearing support with
At least one first gasket is equipped between vehicle frame, first gasket is used to adjust the axial position of axletree；
Using the structure of the first gasket, the first gasket of different number can be installed between fore bearing support and vehicle frame,
And then change the distance that wheel axial direction wheel direction is stretched out, change the distance that wheel stretches out vehicle frame, so that vehicle frame two sides
Wheel centre distance is changed.
Between the rear support and vehicle frame be equipped at least one second gasket, second gasket for adjust axletree with
The angle of horizontal plane；
The quantity of the second gasket can be adjusted using the second gasket construction, so that axletree rotates in perpendicular
Axletree is converted to close to the straight-line displacement of the vertical direction of rear support one end using oscillating bearing as fulcrum by corresponding angle
Angular displacement, so that the position of center line of axletree and wheel meets sets requirement.
The rear support can be moved and be fixed along trolley direction of advance, to adjust wheel axle axis and trolley direction of advance
Vertical missing.
Beneficial effects of the present invention:
1) oscillating bearing structure is used, oscillating bearing can support the rotation of axletree within the set range, so that wheel
Axis can change itself and horizontal plane and the vertical missing with gantry crane trolley direction of advance；After axletree rotation, lead to
It crosses fixed rear support and vehicle frame can be realized the fixation of axletree, keep the assembly precision of axletree, wheel and vehicle frame.
2) structure for using the first gasket can install the first pad of different number between fore bearing support and vehicle frame
Piece, and then change the distance that wheel axial direction wheel direction is stretched out, change the distance that wheel stretches out vehicle frame, so that vehicle frame two sides
Wheel centre distance be changed.
3) quantity that the second gasket can be adjusted using the second gasket construction, so that axletree turns in perpendicular
Corresponding angle is moved, axletree is converted to close to the straight-line displacement of the vertical direction of rear support one end using oscillating bearing as fulcrum
Angular displacement so that the position of center line of axletree and wheel meets sets requirement.
