As preferably, described guide rail is one " work " font guide rail.
In order to understand better and implement, describe the utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing explanation
Fig. 1 is the front section view of walking mechanism of the present utility model.
Fig. 2 is the side sectional view of walking mechanism of the present utility model.
Detailed description of the invention
Please refer to Fig. 1 and Fig. 2, it is respectively front section view and the side sectional view of walking mechanism of the present utility model.
The walking mechanism of trestle trolley of the present utility model, comprises bracing or strutting arrangement 1, lifting gear 2, running gear 3 and drive unit 4.Wherein, it is peripheral that described lifting gear 2 is set in bracing or strutting arrangement 1, and be connected with the trestle trolley main body stone age, with the lifting of control stack abutment vehicle main body; Described running gear 3 is arranged on the bottom of bracing or strutting arrangement 1, in order to this trestle trolley mobile; Described drive unit 4 is in transmission connection, in order to control the work of this running gear 3 with this running gear 3.
Further, the supporting seat 12 that described bracing or strutting arrangement 1 comprises bracing frame 11 and is arranged on bottom bracing frame 11, support frame as described above is fixedly connected with supporting seat.Described lifting gear 2 comprises oil cylinder crane 21, two oil cylinders 22.Described oil cylinder crane 21 is set in the outside of this bracing frame 1.The connection of described oil cylinder crane 21 and this trestle trolley main body; Described two oil cylinders 22 are separately positioned on the both sides of this oil cylinder crane 21; The cylinder body of described two oil cylinders 22 is fixedly connected with oil cylinder crane respectively, and piston rod and this supporting seat 12 of described two oil cylinders are hinged.
Further, described running gear 3 comprises walker 31, is arranged on the road wheel 32 of on this walker 31 and guide rail 33.Described walker 31 is hinged with supporting seat 12; Described road wheel 32 is arranged on the top of guide rail 33.As preferably, described guide rail 33 is one " work " font guide rail.
