The two ends of described walking beam are respectively provided with two road wheels, between two road wheels of same one end, are groove.
Each track is provided with four walking beams, a hydraulic jack of every two groups of walking beams top holder, and each track is provided with two hydraulic jacks; Four groups form two secondary bearing beams of holder, form a hydraulic pressure gauntry crane with another main bolster.
Further, in described walking beam, one of them is active walking beam, each initiatively comprises two road wheels in the every one end of walking beam volume, parallel coaxial settings of two road wheels and being set in rotating shaft by key, between two road wheels, rotating shaft is arranged with spacing sleeve outward, the outside of road wheel is provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap, and end cap is provided with the oil hole towards bearing.
Further, in described walking beam, one of them is active walking beam, each every one end of initiatively walking comprises two road wheels, parallel coaxial settings of two road wheels and being set in rotating shaft by key, between two road wheels, rotating shaft is arranged with spacing sleeve outward, the outside of road wheel is provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap, and end cap is provided with the oil hole towards bearing.
Further, in described walking beam, one of them is driven walking beam, each every one end of driven walking comprises two road wheels, in the parallel coaxial setting of two road wheels and its, be arranged with bearing, bearing carrier ring is located in rotating shaft, the outside that between two bearings in inner side, rotating shaft is provided with spacing sleeve, bearing is outward provided with clamping sleeve, and the two ends of clamping sleeve are provided with end cap.
Principle of work and the beneficial effect of the invention show:
The invention mainly comprises track travel beam and guide rail.
Track adopts box beam structure, and between walking beam, is provided with walking guide position limiter, by track is carried out to large area words, can expand its area of contact, meanwhile, walking beam design be become to tower structure, two ends at walking beam arrange road wheel, make it can carry more weight.
Walking guide position limiter comprises the raised line being positioned on track, be combined with groove with raised line, the groove of the invention adopts road wheel to realize, such as two road wheels are set, between two road wheels, be groove, for coordinating raised line, like this, during walking, the direction that road wheel can extend along raised line is walked, and road wheel can not de-orbit.
