Description
Technical field
The invention belongs to photovoltaic applied technical field, be specifically related to a kind of Long Distances two grades of precision wedge leveller.
Background technology
The present invention devises a kind of Long Distances, the wedge leveller of two grades of precision, relative to common wedge leveller, this mechanism has that stroke is large, setting range is large and the feature of two grades of leveling precision, and its stroke is about two times of common wedge leveller stroke.
The track frame of electro-optical tracking device is supported by three levelling gears, and the scheme of levelling gear generally has three kinds: the first is screw jack formula, and the second is tile deformation type, and the third is wedge type.Wedge leveller structure is simple, and rigidity can be done very large, easily meets the demand of large load.Common wedge leveller structural representation is shown in Fig. 1, and its principle of work is by adjustment leveling bolt, drives sliding block to move left and right, realizes moving up and down of top shoe reach regulating action through voussoir friction pair; As can be seen from Figure 1, if want the adjustment on a large scale realizing levelling gear, in the isogonal situation of friction pair, the shift motion of sliding block can only be increased, and the increase of stroke, directly can have influence on the length of levelling gear, and the length of levelling gear is impossible indefinite extension.
Summary of the invention
Technical matters to be solved by this invention is, not enough for prior art, there is provided a kind of when not changing levelling gear length, by improving the upper and lower slide block structure form of levelling gear, the stroke of levelling gear is doubled, and there are Long Distances two grades of precision wedge leveller of two grades of Adjustment precision.
The technical solution adopted in the present invention is:
A kind of Long Distances two grades of precision wedge leveller, comprise bearing, linkage levelling screw, female sliding block, top shoe and clamping screw, wherein said bearing is semiclosed hollow cavity, inside be provided with female sliding block, described linkage levelling screw is through the sidewall of bearing, be fixed on female sliding block by screw thread, described clamping screw, through top shoe and female sliding block, is fixed on bottom surface of support saddle by screw thread.
Be provided with two sub-sliding blocks in described female sliding block, sub-sliding block is fixed in female sliding block by folding and unfolding screw rod and two guideposts, and described folding and unfolding screw rod both sides are provided with reverse thread.
Described top shoe is made up of two inclined-planes A, the B intersected.
Described female sliding block and sub-sliding block are two contrary inclined-planes, and the inclined-plane of female sliding block is corresponding with the inclined-plane A of top shoe, and the inclined-plane of sub-sliding block is corresponding with the inclined-plane B of top shoe.
The invention has the beneficial effects as follows:
1. this leveling structure is by the collapsible primary and secondary sliding block with being separated of design, and devises the top shoe of corresponding construction form, when not changing levelling gear length dimension, and the ability achieve Long Distances, adjusting on a large scale.
2., by adopting the mode of primary and secondary slide block different angles friction pair, achieve the ability in levelling gear adjustment process with two grades of leveling precision.
3. Long Distances two grades of precision wedge leveller of design are when not change structure length dimension, be provided with the ability of Long Distances, large setting range and two grades of precision, thus the requirement reduced ground flatness, enhance the ability of anti-interference, add leveling capability.

Embodiment
Below in conjunction with drawings and Examples, a kind of Long Distances provided by the invention two grades of precision wedge leveller are introduced:
As shown in Figure 2, a kind of Long Distances two grades of precision wedge leveller, comprise bearing 1, linkage levelling screw 2, female sliding block 3, top shoe 6 and clamping screw 7, wherein said bearing 1 is semiclosed hollow cavity, inside be provided with female sliding block 3, described linkage levelling screw 2, through the sidewall of bearing 1, is fixed on female sliding block 3 by screw thread, described clamping screw 7, through top shoe 6 and female sliding block 3, is fixed on bearing 1 bottom surface by screw thread.
As shown in Figure 3, be provided with two sub-sliding blocks 5 in described female sliding block 3, sub-sliding block 5 is fixed in female sliding block 3 by folding and unfolding screw rod 4 and two guideposts 8, and described folding and unfolding screw rod 4 both sides are provided with reverse thread.
As shown in Figure 4, described top shoe 6 is made up of two inclined-planes A, the B intersected.
Described female sliding block 3 and sub-sliding block 5 are two contrary inclined-planes, and the inclined-plane of female sliding block 3 is corresponding with the inclined-plane A of top shoe 6, and the inclined-plane of sub-sliding block 5 is corresponding with the inclined-plane B of top shoe 6.
Linkage levelling screw 2 realizes the slide anteroposterior of sliding block relative to bearing 1, thus makes sliding block head on top shoe 6 to move up and down; Female sliding block 3 is connected by folding and unfolding screw rod 4 with two sub-sliding blocks 5, folding and unfolding screw rod 4 both sides are reverse threads, realize the object that two sub-sliding blocks 5 enter female sliding block 3 cavity simultaneously or shift out, and female sliding block 3 and sub-sliding block 5 are two contrary inclined-planes, corresponding with A, B inclined-plane of top shoe, top shoe is made up of two inclined-planes A, the B intersected, and sees Fig. 3, Fig. 4, Fig. 5; In the different phase of levelling gear work, A inclined-plane, B inclined-plane respectively with contact of incline plane or the disengaging of female sliding block 3 and sub-sliding block 5; When different angles are got with the B inclined-plane between sub-sliding block 5 and top shoe 6 in A inclined-plane between female sliding block 3 and top shoe 6, two grades of leveling precision in leveling process can be realized.
When adjustment is risen, two sub-sliding blocks should be kept by the adjustment of folding and unfolding screw rod all to be entered into the state of the respective cavities of female sliding block, first rotate linkage levelling screw, female sliding block is moved forward, the now inclined-plane of female sliding block and the A contact of incline plane of top shoe, promotes top shoe by female sliding block and rises; When female sliding block has arrived range, adjustment folding and unfolding screw rod makes two sub-sliding blocks shift out from the cavity of female sliding block, the B contact of incline plane that now inclined-plane of sub-sliding block is corresponding to top shoe, then linkage levelling screw is rotated in the opposite direction, screw rod promotes female sliding block and moves backward together with two sub-sliding blocks, now the inclined-plane of female sliding block and the A inclined-plane of top shoe depart from, and sub-sliding block promotes top shoe to be continued to rise.
The course of work that adjusting mechanism declines is contrary.
