Embodiment
The utility model preferred embodiment is illustrated below in conjunction with accompanying drawing：
As shown in Figures 1 to 4, a kind of main shaft connection structure being used in flat single-shaft tracking system, including it is fixedly connected on branch
Bearing block 2, its middle part on support column 1 are arranged on the rotary shaft 3 on bearing block 2, in addition to are arranged on the both ends of rotary shaft 3 and use
In the swelling connected structure of connection live spindle 4, the swelling connected structure includes the U-shaped for being fixedly installed on the end of rotary shaft 3
Frame 5, the fixed plate 6 for being arranged on the end of U-frame 5, penetratingly it is arranged on the regulation spiral shell concentric in fixed plate 6 and with rotary shaft 3
Bar 7, the cone 8 for being arranged on the one end of adjusting screw rod 7, the adjusting nut 9 being adapted with adjusting screw rod 7, multiple it is coated on outside cone 8
Surface simultaneously can hold the expanding block 10 in the inner side of live spindle 4, and U-frame 5 can facilitate the regulation of adjusting nut 9 to operate, cone 8
Four can have been set to adapt to use situation of the square steel tube as live spindle 4, three or six can also be set to adapt to
Using situation of the round steel pipe as live spindle 4；
Square steel tube is used due in flat single-shaft tracking system as live spindle 4, so the quantity of expanding block 10 is four more
Individual to be fitted on 4 four medial surfaces of live spindle, expanding block 10 is coated on the outer surface of cone 8 and forms square contour, the party
Shape profile is shown by being arranged on the wing plate of the both sides of expanding block 10, and the wing plate adds expanding block 10 and rotation is led
The contact area of the inner surface of axle 4, it can prevent adjacent expanding block 10 from live spindle 4 is covered into deformation, when cone 8 is square cone
It can ensure that expanding block 10 does not produce circumferential movement on the outer surface of cone 8；
Rotary shaft 3 and live spindle 4 need strict guarantee circumferentially fixed, although one end of expanding block 10 can closely cover
On the one side of fixed plate 6, circumferential misalignment is avoided using frictional resistance, but live spindle 4 is born in actual moving process
Reciprocal circumferential active force, is ensured circumferentially fixed not fool proof using frictional resistance, is easily produced sliding friction, is influenceed
The angular adjustment of photovoltaic panel, therefore be provided with the one side of fixed plate 6 by center outwards in the projection 13 of dispersion shape, swelling
The one end of block 10 is provided with the chute 14 being adapted with projection 13, and projection 13 can set the strip of squarely, quantity and swelling
Block 10 is all four, and chute 14 similarly sets four, and rotary shaft 3 and rotation are realized using the cooperation of projection 13 and chute 14
Main shaft 4 it is circumferentially fixed, expanding block 10 slides along projection 13 when expanding laterally；
In actual application, live spindle 4 also subject to certain axial tension stress, now on expanding block 10, with
Anti-slip texture 11 is set at the binding face of live spindle 4, frictional resistance, increase structural strength can be increased, effectively avoid swelling
Relative slip is produced between block 10 and live spindle 4, anti-slip texture 11 can set toothing；
Because expanding block 10 is coated on the outer surface of cone 8, now wrapped between the outside of expanding block 10 and live spindle
Rubber sleeve 12 is covered, rubber can be carried during practical set with playing a part of expanding block 10 being fixed in cone 8
Set 12 directly assembling, also dismountable rear assembling；Rubber sleeve 12 is such as carried to be assembled it is ensured that its thickness is not more than anti-slip line
The depth of reason 11.
Operating process of the present utility model and action principle：
Cone 8 and the two parts of expanding block 10 are first inserted into the inner side of live spindle 4, fixed plate is then located at by spanner rotation
The nut of regulation 9 of 6 sides, adjusting nut 9 are held in fixed plate 6 and pull adjusting screw rod 7 overhanging, and the one end of expanding block 10 is held
On the one side of fixed plate 6, expanding block 10 is driven square along the length of projection 13 by the inclined-plane of cone 8 during cone 8 is overhanging
Expanded to surrounding, and then the inwall of live spindle 4 is held, realize the linking and fixation of rotary shaft 3 and live spindle 4；To increase
Add tensioning function of the adjusting nut 9 to adjusting screw rod 7, double nut locking mechanism or increase elastic stopping pad can be used to reach
