Description
Technical field
The utility model is related to a kind of crane trolley wheels, and in particular to a kind of crane trolley wheel with function of seismic resistance
Structure.
Background technology
Crane belongs to one kind of hoisting machinery, is a kind of hoisting and hanging machinery being widely used in harbour, goods yard.Especially with
The rapid development of China's shipping industry, crane is lifted and transported in operation in the container at each harbour in China and other items and plays
Irreplaceable role.Harbour and goods yard also constantly propose new requirement to the Lifting Capacity of crane, therefore crane is not
It is disconnected to develop towards enlargement, high speed direction.The enlargement development of crane also brings a series of problems, such as its antiseismic energy
Power can weaken.The earthquake centre in multiple times occurred both at home and abroad in recent years, crane cause crane by serious earthquake disaster
Trolley damage, supporting leg damage, portal-framed structure deformation even complete machine are caved in, and huge economic loss even personnel's wound is caused
It dies.
Utility model content
In view of the above shortcomings of the prior art, technical problem to be solved in the utility model is：One kind how is provided to exist

In the present invention, the bearing block at bottom of frame both ends provides support for axletree, while positioning sleeve is to wheel
Axially position is carried out, in order to which the groove on wheel makes crane trolley be moved after coordinating with traveling steel rail, in this way not
When an earthquake occurs, the service condition of this car wheel structure and the service condition difference of conventional structure are little.But occur in earthquake
When, seismic wave transmits on the ground, since groove and the traveling steel rail on wheel coordinate, traveling steel rail can by its by
The active force in horizontal radial direction be transmitted on wheel.Therefore wheel is similarly subjected to the active force on radially direction；By
In positioning sleeve to the limitation on wheel axis direction, wheel can transmit active force in the shaking on radially direction
To positioning sleeve, the other end of positioning sleeve is connected in the inner ring of bearing, and bearing fixation in bearing block can not move, positioning
Putting on will be bad by the inner ring top of bearing after active force passes over, and the inner ring and outer ring of bearing is made to misplace, and is positioned such that set just
It its axis direction can slidably reciprocate in axletree upper edge；The spring on positioning sleeve will accordingly generate compressive deformation at this time, with
This absorbs the energy of seismic wave, achievees the purpose that damping, reduces the shaking of crane trolley superstructure；In addition bearing and wheel
Axis interference connects, and bearing inner race will result in the movement of axletree in moving process, therefore, in wheel shaft end head and bearing block
Clearance space between wall can be that the movement of axletree provides adjusting space.
As an optimization, the bearing block includes pedestal ontology, and pedestal ontology is fixedly connected on by bearing block mounting screw
On the vehicle frame, offered respectively on the inner face and outer end face of pedestal ontology the interior installing hole being arranged with the coaxial bearing and
Outer installing hole, transparent cover is additionally provided on the inner face of pedestal ontology, and transparent cover lid closes at interior installing hole and installs spiral shell by transparent cover
Nail is fixedly connected on pedestal ontology, and the through-hole for making the axletree and the positioning sleeve pass through, seat are offered in transparent cover
Boring cover is additionally provided on the outer end face of body ontology, boring cover lid is closed at outer installing hole and is fixedly connected on by boring cover mounting screw
On pedestal ontology, transparent cover is equipped with a circle for being connected to towards the side of interior installing hole centered on the axis of the bearing
The transparent cover baffle ring on bearing outer ring inner face is stated, the ring centered on the axis of the bearing is set boring cover towards the side of outer installing hole
There is boring cover baffle ring of the circle for being connected on the bearing outer ring outer end face.Positioned at pedestal ontology both sides transparent cover and boring cover just
In the installation and maintenance of bearing, the axis limit to bearing is in addition also acted, while the outer ring of bearing being fixed, so as to
The dislocation damage of bearing internal external circle when earthquake occurs.
As an optimization, the spacing block set is the wheel baffle ring set around the positioning sleeve circumferential direction ring, and wheel baffle ring is located at institute
Positioning sleeve is stated towards one end of the wheel, wheel baffle ring is towards wheel side side and the positioning sleeve towards the vehicle
Wheel side side flushes and perpendicular with the positioning sleeve axis direction.Wheel ring packing gear not only limits spring, simultaneously also
Increase the contact area between wheel, enable the ground seismic wave function power that wheel is subject to it is good pass to positioning sleeve.
As an optimization, the bearing is taper roll bearing.Taper roll bearing can bear certain axial force,
Not when an earthquake occurs, it can be ensured that wheel will not shake along its axial direction, so that crane trolley normal operation works.
In conclusion the beneficial effects of the utility model are：The utility model is simple in structure, can be initial in seismic wave
The route of transmission that its active force is cut off on transmission path reduces the shaking of crane trolley superstructure, it is ensured that crane trolley
The safety of agent structure.
