Abstract
The utility model discloses a device for connecting an end beam and a main beam of a crane, and belongs to the technical field of cranes. The device comprises a first bushing fixedly arranged on the main beam of the crane, a second bushing fixedly arranged on the end beam of the crane, and a articulated shaft passing through the first and the second bushings, wherein an elliptic skid road is arranged on the second bushing, and the articulated shaft is restrictively arranged inside the elliptic skid road. According to the utility model, the end beam is allowed to move with a certain displacement relative to the main beam, so that the travel wheels on the end beam and the main beams act on the track all the time during the travel process, and the pressures on the travel wheels are balanced. The device is widely applied in the crane manufacturing industry.
Description
Technical field
The utility model relates to the hoisting crane technical field, relates in particular to a kind of crane end carriage and girder connecting device.
Background technology
The end carriage and the girder of hoisting crane all are fixedly installed togather usually, and road wheel all is installed on girder and the end carriage, and road wheel is walked in orbit; When the track unfairness; The unsettled state of road wheel on the end carriage can appear, and the instantaneous increase of the wheel load of other road wheels meeting like this is big to the pressure change suddenly of track; Directly workshop steel structure is caused harmful effect, have huge potential safety hazard.
The utility model content
The utility model technical matters to be solved is: a kind of crane end carriage and girder connecting device are provided; Can make the relative girder of end carriage that certain displacement is arranged; Make on end carriage and the girder road wheel in the process of walking all the time the effect in orbit, balance the wheel load of road wheel.
For solving the problems of the technologies described above; The technical scheme of the utility model is: crane end carriage and girder connecting device; Comprise first bearing shell that is fixedly installed on the said crane girder, be fixedly installed in second bearing shell on the said crane end carriage, run through the jointed shaft of said first bearing shell and second bearing shell; Said second bearing shell is provided with oval slideway, and said jointed shaft constraint is installed in the said oval slideway.
As a kind of improvement, a side of said end carriage is installed with locating plate, and the end face of said second bearing shell relies on the said locating plate.
As a kind of improvement, be provided with between said jointed shaft and the girder and be used to limit the axially movable positioning plate of said jointed shaft, said positioning plate constraint is installed on the said jointed shaft.
As a kind of improvement, be provided with dividing plate between said first bearing shell and second bearing shell.
As a kind of improvement, be provided with some holding screws between said second bearing shell and the end carriage, described some holding screws are the center annular array distribution with the center of gyration of said jointed shaft.
After having adopted technique scheme; The beneficial effect of the utility model is: because girder and end carriage are installed together through jointed shaft, the jointed shaft constraint is installed in the oval slideway of second bearing shell, and end carriage just can have certain moving range with respect to girder like this; Concrete movable length can be decided according to the sliding length of jointed shaft in oval slideway; When the track unfairness, end carriage can have certain adjustment degree, can be so that road wheel acts in orbit all the time; Be unlikely to unsettled and cause the wheel load of other road wheels to increase suddenly, eliminated potential safety hazard.
Owing to designed the axially movable positioning plate of restriction jointed shaft, make jointed shaft can not deviate from first bearing shell and second bearing shell, end carriage was guaranteed with being connected of girder.
Owing to be provided with some holding screws between second bearing shell and the end carriage, prevented that effectively second bearing shell from rotating, and guaranteed the direction of slip of jointed shaft in slideway.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the running condition scheme drawing of the utility model embodiment;
Fig. 2 is the schematic cross-section of second bearing shell;
Among the figure: 1, end carriage, 2, girder, 3, jointed shaft, 4, first bearing shell, 5, second bearing shell, 51, oval slideway, 6, locating plate, 7, positioning plate, 8, dividing plate, 9, holding screw.
The specific embodiment
As depicted in figs. 1 and 2; A kind of crane end carriage and girder connecting device comprise first bearing shell 4 that is fixedly installed on the said crane girder 2, are fixedly installed in second bearing shell 5 on the said crane end carriage 1, run through the jointed shaft 3 of said first bearing shell 4 and second bearing shell 5, and said second bearing shell 5 is provided with oval slideway 51; Said jointed shaft 3 constraints are installed in the said oval slideway 51; From the technical matters that the utility model solved, those skilled in the art can obtain, and the major axis of oval slideway 51 should be perpendicular to the direction of road wheel track; Like this; Road wheel is in operational process, and end carriage 1 corresponding girder 2 has an adjustment amount, and road wheel acts in orbit all the time.From above-mentioned design, oval slideway 51 can have various deformation, and for example, long gain or slotted hole all can play this effect, all belong to the protection domain of the utility model.
One side of said end carriage 1 is installed with locating plate 6; The end face of said second bearing shell 5 relies on the said locating plate 6; Be provided with between said jointed shaft 3 and the girder 2 and be used to limit said jointed shaft 3 axially movable positioning plates 7; Said positioning plate 7 constraints are installed on the said jointed shaft 3, are provided with dividing plate 8 between said first bearing shell 4 and second bearing shell 5.
Be provided with some holding screws 9 between said second bearing shell 5 and the end carriage 1; Described some holding screws 9 are the center annular array distribution with the center of gyration of said jointed shaft 3; Prevented that effectively second bearing shell 5 from rotating, and guaranteed the direction of slip of jointed shaft 3 in slideway.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within the protection domain of the utility model.
