Summary of the invention
The purpose of this utility model is the defect for current wheel-track type girder gantry crane travel structure, provides a kind of weight capacity large, interior outside stress balance, the wheel-track type girder gantry crane running mechanism of long service life.
To achieve these goals, the technical solution adopted in the utility model is: comprise that two groups of structures are identical, the sub-agencies of installing in pairs during work; Every component mechanism includes the flange for being connected with supporting leg before and after lifting beam machine, flange is movably installed in the middle part of the first saddle beam, the two ends of the first saddle beam bottom are movably installed with for forming the second saddle beam in double rail type track, the two ends of each the second saddle beam are movably installed with bogie frame, inner side chassis is installed on two bogie frames in inner side, on the bogie frame of two, outside, energy storage side stage car is installed.
Described flange is movably installed in the middle part of the first saddle beam by the first bearing pin; The two ends of the first saddle beam bottom are movably installed with for forming the second saddle beam in double rail type track by the second bearing pin; The two ends of each the second saddle beam are movably installed with bogie frame by the 3rd bearing pin.
The 3rd described bearing pin is installed on the middle part of bogie frame, and each chassis includes two wheels, and is positioned at the two ends of institute's erecting bed vehicle frame bottom.
Described chassis is all provided with drive motor and the speed reduction gearing for braking in track outside.
Described chassis one end is provided with for guaranteeing the rail clamping device of lifting beam machine trend.
Compared with prior art, the utility model is connected with supporting leg before and after lifting beam machine by flange, flange is movably installed in the middle part of the first saddle beam, the two ends of the first saddle beam bottom are movably installed with two the second saddle beams, the two ends of each the second saddle beam are movably installed with chassis by the 3rd bearing pin, owing to having adopted flexible connection, have guaranteed that rotation freely, therefore after being under pressure, can make the stressed even of energy storage side stage car and inner side chassis, reduce the excessive wearing and tearing that cause of inner side chassis pressure; By the second saddle beam, realize the two-orbit system of lifting beam machine running mechanism, improved on the one hand the weight capacity of lifting beam machine running mechanism, promoted on the other hand stability and the guidance quality of device.By in conjunction with variable-frequency control technique, the utlity model has the features such as driveaway operation is steady, and impulsive force is little, and braking is reliable, and contraposition is accurate, device lifetime is long, can effectively reduce lifting beam machine and rupture and cause capsizing case odds because running mechanism is unexpected.
Further, each chassis of the utility model includes two wheels, and be installed on the two ends of bogie frame, the 3rd bearing pin is installed on the middle part of bogie frame, and two wheels can carry out transverse rotation around the 3rd bearing pin, thereby reduces inboard wheel because of the stressed excessive wearing and tearing that cause, on the other hand, the utility model amounts to 16 wheels, and weight capacity is better, and resistance to overturning is better.
Further, the utility model chassis is all provided with motor and the speed reduction gearing for braking for driving in track outside, by adopting AWD drive scheme, can carry out real-time actv. control to chassis on the one hand, four motors and speed reduction gearing are distributed on outside on the other hand, stressed inside can active balance wheel, reduce inboard wheel wearing and tearing.
