Beneficial effects of the present invention:The design that the present invention passes through oblique single shaft front support structure and rear support structure, Neng Gou
When ground sinks, it is ensured that the normal rotation of main shaft, while, it is ensured that the stress balance of support, will not be because of long-term some stress
And damage, efficiently solve that outdoor solar inclined single-shaft linkage support service life is short, maintenance cost problem high.Branch before described
Support structure by the way of support shaft is combined with rotary shaft by intermediate ball, under basis drives front column slight before the clump
When heavy, make support shaft and rotary shaft not on the same axis, but have no effect on the normal rotation of main shaft, before effectively solving clump
The problem that basis sinks.When basis sinks to telling somebody what one's real intentions are before clump, main shaft angle is driven when changing, back support rod can be around
Rear column lower connecting base is rotated, so as to meet the requirement that rear-end of spindle highly changes, it is ensured that back support rod gives main shaft foot
Enough supports, simultaneously as being bearing pin connection between connecting rod and between connecting rod and slave arm so that connecting rod has certain oscillating quantity
Without the normal transmission of influence, additionally, the gap between sliding bottom anchor ear and main shaft, can also discharge to a certain extent due to
The stress concentration that spindle tilt changes and causes, so as to avoid damaging the problem of sliding bottom anchor ear.If additionally, main shaft edge
When being axially moved, can be rotated around bearing pin on rear column base plate by rear column lower connecting base, keep back support rod
Stress balance, prevents back support rod receipts torsion excessive and damages.When spindle tilt is too big, by the rotation of back support rod
During through the requirement that can not meet stress balance, can also by adjusting the cooperation position of the threaded rod on back support rod and nut,
Back support rod is integrally shortened or is extended, meet the support requirement of main shaft.One or two hair after clump in basis
When giving birth to heavy, the stress that can make support by the adjustment of back support rod reaches balance, is propped up after not resulting in one of them
The stress of strut is excessive and damages.By a series of adjustment of structures of the invention, but certain stress it is excessive when, be exactly by it
His structure rotates the stress balance for carrying out the whole support of adjust automatically, and so as to avoiding the damage of support, effective extending bracket makes
Use the life-span.
