Described gear III is meshed with the gear II when oil cylinder is failure to actuate, and in the time of cylinder action, gear III and gear II are thrown off, and described gear I is meshed with geared sleeve.
Between described geared sleeve and gear III, by several coupled axle-pins, be connected.
The width of described driving gear is greater than the shift motion length of intermediate propeller shaft.
When oil cylinder moves, gear III and gear II are not meshed, and the rotation of motor drives main shaft by shaft coupling and rotates at top gear after driving gear and gear III, gear III and the transmission of gear II, realize the little moment of torsion output of high speed; Move down when cylinder action promotes intermediate propeller shaft, wait gear III and gear II and throw off, described gear I is meshed with geared sleeve, and now main shaft rotates at low or first gear, realizes low-speed big output, and compact conformation, realize all-gear drive, reliability and durability.
beneficial effect
The present invention relates to the T-shaped ram in integral type all-gear drive gantry, simple in structure, used the integral structure that has installed the speed-change and gearshift device in ram inside additional, and employing all-gear drive, cancelled original expensive external gearbox and belt transmission, eliminated the dependence to external gearbox, structure is compacter, fault rate reduces greatly, and maintenance cost also reduces greatly.
The accompanying drawing explanation
Fig. 1 is that integral body of the present invention is partly cutd open structure chart;
Fig. 2 is the structure chart of speed changing structure of the present invention when top gear;
Fig. 3 is the structure chart of speed changing structure of the present invention when low or first gear.
