Abstract
The utility model discloses a large vehicle running gear full-circle-swinging hinged shaft mounting structure comprising a cross beam and running hinge support arranged at the lower end of the cross beam, wherein a center shaft for connecting the cross beam with the running hinge support is arranged in the center of the cross beam, a housing for sealing the center shaft is arranged at the upper end of the cross beam, and a friction plate is arranged between the cross beam and the running hinge support. The large vehicle running gear full-circle-swinging hinged shaft mounting structure has the advantages that the fine adjustment and rotation of the running hinge support can be realized by taking the center shaft as a center, repeated damages to a large vehicle running gear caused by civil foundations are reduced, and the mounting structure adapts to civil engineering infrastructures; the friction plate is arranged between the cross beam and the running hinge support and a gap can be adjusted by adding the friction plate, so that if whole machine delivery is needed, the running gear does not need to be increased again to realize the functions of fine adjustment and rotation of the large vehicle running gear, and the abrasion of wheels of the large vehicle running gear and the transportation cost of whole machine delivery are reduced.
Description
Technical field
The utility model relates to a kind of hoisting crane accessory structure, and specifically a kind of cart walking mechanism full circle swinging hinge mounting structure, belongs to elevator machinery technical field.
Background technology
The weight-lifting equipment center member lower flange plate of prior art and walking hinged-support flanged plate are all the mode that adopts fillet weld be rigidly connected (or adopting high strength bolt); Adopt existing this connection mode to have following defect: 1, crossbeam and walking hinged-support adopt and be rigidly connected, stricter to the requirement of foundation of civil work facility, large Car Track is uneven, when straightness accuracy is bad, cart walking mechanism cannot be finely tuned voluntarily, and wheel and track are prone to gnaws rail phenomenon; 2, cannot utilize existing operating unit to realize complete machine delivery, need to again increase operating unit, realize the traversing of complete machine.
Summary of the invention
The technical problems to be solved in the utility model is to provide and a kind ofly can realizes the microscopic carvings of cart walking mechanism and the cart walking mechanism full circle swinging hinge mounting structure of spinfunction.
In order to solve the problems of the technologies described above, cart walking mechanism full circle swinging hinge mounting structure of the present utility model, comprise crossbeam and the walking hinged-support that is arranged on crossbeam lower end, the center of crossbeam is provided with one for the center shaft of connecting cross beam and walking hinged-support, the upper end of crossbeam is provided with the case for center seal axle, between crossbeam and walking hinged-support, is provided with friction lining.
The upper end of described crossbeam is also provided with one for the back-up ring of fixed center axis.
Hinged-support is vertical arranges with walking for described center shaft, in described center shaft, is provided with oilhole.
On described friction lining, be provided with for depositing the oil groove of lubricating oil.
Between described center shaft and walking hinged-support, adopt transition fit.
The utility model has the advantage of:
The center shaft with walking hinged-support for connecting cross beam arranging due to the center of crossbeam, it is that round dot is realized fine setting and rotation that the hinged-support that can make thus to walk be take the center of center shaft, reduce the repeat destruction of foundation of civil work reason to cart walking mechanism, adapted to foundation of civil work facility; The friction lining arranging between crossbeam and walking hinged-support, can utilize and add friction lining adjusting play, if therefore while needing complete machine delivery without again increasing operating unit, just can realize fine setting and the spinfunction of cart walking mechanism, reduce the traffic cost of wearing and tearing and the complete machine delivery of cart walking mechanism wheel.

Fig. 2 is the side-looking structural representation of the utility model cart walking mechanism full circle swinging hinge mounting structure;
Fig. 3 is the structural representation of friction lining in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, cart walking mechanism full circle swinging hinge mounting structure of the present utility model is described in further detail.
As described in Figure, cart walking mechanism full circle swinging hinge mounting structure of the present utility model, comprises crossbeam 1 and is arranged on the walking hinged-support 2 of crossbeam lower end, can detour the away central rotation of hinged-support of crossbeam; The center of crossbeam 1 is provided with one for the center shaft 3 of connecting cross beam and walking hinged-support, between center shaft 3 and walking hinged-support 2, adopt transition fit, center shaft 3 is with the walking vertical setting of hinged-support 2 and in center shaft 3, be provided with oilhole 6, oilhole reduces the friction drag between logical axle and axle sleeve, realizes relatively rotating of crossbeam and walking hinged-support; The upper end of crossbeam 1 is provided with the case 4 for center seal axle 3, between crossbeam 1 and walking hinged-support 2, be provided with friction lining 7, the friction lining fine setting crossbeam of the dimensioned moulding that need to detect when installing should be made generation error, the gap of the amount of friction producing when friction lining 7 can be used to repay crossbeam and walks relative displacement between hinged-support.
Further the upper end of crossbeam 1 is also provided with one for the back-up ring 5 of fixed center axis, is provided with for depositing the oil groove of lubricating oil on friction lining 7, reduces the friction drag between crossbeam and walking hinged-support.
During installation, center shaft 3 is through the through hole at walking hinged-support 2 centers, the friction lining 7 processing in installation, the data that detect crossbeam 1 both sides, errorless rear symmetry is installed in crossbeam 1 endoporus, and level and the center of fine setting both sides walking hinged-support 2 are high, finally fill back-up ring 5, twist the bolt on good case 4.
