Abstract
The invention relates to a supporting device for a cart travelling perpendicular hinge shaft of a portal crane, which comprises a balance beam and a bogie frame, and is characterized by further comprises a perpendicular shaft, a friction plate, a spindle seat and a transverse shaft, wherein the spindle seat and the perpendicular shaft are welded into a whole; the perpendicular shaft is in clearance fit with the balance beam, thereby ensuring that the perpendicular shaft can rotate; the friction plate is arranged on the contact surface between the spindle seat and the balance beam; and the bogie frame and the spindle seat are connected through the transverse shaft. The supporting device has simple and reasonable structure, and can prolong the service life of wheels of the crane, reasonably solve the problems of inconvenient maintenance and operation of a cart traveling wheel group, improve the safety and the working efficiency of maintenance staff, lead the equipment operation to be safe and reliable and improve the operation efficiency of the whole machine.
Description
Technical field
The invention belongs to technical field of engineering machinery, relate to a kind of improvement of handling equipment, specifically is that a kind of span winch cart moves vertical hinge bearing set.
Background technology
The traveling mechanism of the larger traveller of span winch is an inoperative mechanism, i.e. this mechanism run with load not just is used for adjusting the job position of hoisting crane.In cart operation work, reasons such as elastic deformation overproof owing to the installation of wheel and track, metal construction can cause gnaws the rail phenomenon, and the surface heat of wheel own is handled and do not reached technical requirements in addition, and wheel influences normal operation because of wearing and tearing, peeling off easily.Therefore in order to guarantee that cart normally moves, finish the maintenance and the replacing of set of wheels as early as possible, directly have influence on the work efficiency (, because of being subjected to the restriction of operational space, and potential safety hazard being arranged) of complete machine maintainer's ten inconvenience especially at the water siding track.
Summary of the invention
The objective of the invention is at above shortcomings in the prior art, provide a kind of can be simple in structure, ingenious, span winch cart safe and reliable to operation moves vertical hinge bearing set,
This operation bearing set can effectively overcome the problem that installation is overproof and maintenance operation is inconvenient of wheel and track, improves hoisting crane wheel service life, improves maintenance work efficient and ensures maintainer's safety.
According to technical scheme provided by the invention: a kind of cart operation bearing set of span winch, comprise equalizing bar, bogie frame, feature is: also comprise vertical axis, friction lining, spindle seat, transverse axis, described spindle seat and vertical axis are integrally welded; Adopt free-running fit between vertical axis and the equalizing bar, guarantee that vertical axis can rotate; The contact surface of spindle seat and equalizing bar is provided with friction lining; Link to each other by transverse axis between bogie frame and the spindle seat.
The present invention is simple and reasonable, can effectively improve hoisting crane wheel service life, rationally solve the problem of cart operation wheel group maintenance operation inconvenience, improve maintainer's safety and work efficiency, make equipment operation safe and reliable, improved the operating efficiency of complete machine.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the A-A cutaway view among Fig. 1.
The specific embodiment
Below in conjunction with drawings and Examples the present invention is described in further detail.
As Fig. 1～shown in Figure 2, comprise equalizing bar 1, vertical axis 2, friction lining 3, spindle seat 4, transverse axis 5, bogie frame 6.
Bogie frame inner utilization axletree of the present invention is equipped with set of wheels 7, adopts vertical hinge connection bearing set connecting between bogie frame 6 and the equalizing bar 1.Described vertical hinge connects bearing set and adopts spindle seat 4 and vertical axis 2 integrally welded; Adopt free-running fit between vertical axis 2 and the equalizing bar 1, guarantee that vertical axis 2 can rotate; Spindle seat 4 is a friction lining 3 with the contact surface of equalizing bar 1; Link to each other by transverse axis 5 between bogie frame 6 and the spindle seat 4.Described friction lining 3 adopts the HT300 material to form.
Principle of work of the present invention is as follows:
In the operational process of hoisting crane, because the precision of wheel and big Car Track assembling is local overproof, can cause the generation of hoisting crane wheel gnawing rail phenomenon, when above-mentioned phenomenon takes place, the direction that vertical hinge device can automatic compensation be gnawed the rail wheel is moved hoisting crane under normal condition.
Under the normal condition, owing to be subjected to the effect of hoisting crane weight, equalizing bar connects bearing set and walking carriage frame with vertical hinge, set of wheels is stressed jointly; When set of wheels need overhaul and change, available jack is with the equalizing bar jack-up of this set of wheels, bogie frame, set of wheels are not subjected to the effect of hoisting crane weight at this moment, bogie frame can rotate with vertical hinge, the maintainer can rotate to set of wheels suitable position very easily and operate, and is not subjected to constraint, the restriction of operational space.
