Description
Technical field
The invention belongs to photovoltaic applied technical field, and in particular to a kind of big two grades of precision wedge type leveling machines of stroke
Structure.
Background technology
The present invention devises a kind of big stroke, and the wedge leveller of two grades of precision, the mechanism is relative to common wedge
Iron formula levelling gear has that stroke is big, adjusting range is big and the characteristics of two grades of leveling precision, and its stroke is common wedge type leveling
Two times or so of actuator travel.
The track frame of electro-optical tracking device is supported by three levelling gears, and the scheme of levelling gear typically has three kinds：First
Kind, it is screw jack formula, second, be tile deformation type, and the third, is wedge type.Wedge leveller knot
Structure is simple, and rigidity can be made very big, readily satisfy the demand of big load.Common wedge leveller structural representation is shown in figure
1, its operation principle is by adjusting leveling bolt, driving sliding block to move left and right, top shoe is realized by voussoir friction pair
Move up and down to reach adjustment effect；It will be seen from figure 1 that if it is desired to a wide range of adjustment of levelling gear is realized, in friction pair
In the case of isogonal, the shift motion of sliding block can only be increased, and the increase of stroke, directly influence whether levelling gear
Length, and the length of levelling gear is impossible indefinite extension.
The content of the invention
The technical problems to be solved by the invention are, in view of the shortcomings of the prior art, providing one kind is not changing levelling gear
In the case of length, by improving slide block structure form above and below levelling gear, double the stroke of levelling gear, and with two
Two grades of precision wedge levellers of big stroke of shelves Adjustment precision.
The technical solution adopted in the present invention is：
A kind of two grades of precision wedge levellers of big stroke, including bearing, linkage levelling screw, female sliding block, top shoe and
Clamping screw, wherein described bearing is semiclosed hollow cavity, interior to be provided with female sliding block, described linkage levelling screw passes through bearing
Side wall, be threadedly secured on female sliding block, the clamping screw passes through top shoe and female sliding block, is threadably secured
In bottom surface of support saddle.
Two sub- sliding blocks are provided with described female sliding block, sub- sliding block is fixed by folding and unfolding screw rod and two leads
In female sliding block, 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- the sliding block inclined-plane that to be two opposite, the inclined-plane of female sliding block and the inclined-plane of top shoe
A is corresponding, and the inclined-plane of sub- sliding block is corresponding with the inclined-plane B of top shoe.
The beneficial effects of the invention are as follows：
1. the leveling structure and devises corresponding construction form by designing collapsible and separation primary and secondary sliding block
Top shoe, in the case where not changing levelling gear length dimension, the ability that realize big stroke, adjusts on a large scale.
2. by using the mode of primary and secondary sliding block different angle friction pair, realizing during levelling gear adjusts has two
The ability of shelves leveling precision.
3. two grades of precision wedge levellers of big stroke of design have in the case where not changing structure length size
The ability of big stroke, big adjusting range and two grades of precision, so as to reduce the requirement to ground flatness, enhances anti-interference
Ability, add leveling capability.

Embodiment
A kind of big two grades of precision wedge levellers of stroke provided by the invention are entered with reference to the accompanying drawings and examples
Row is introduced：
As shown in Fig. 2 a kind of two grades of precision wedge levellers of big stroke, including bearing 1, linkage levelling screw 2, female downslide
Block 3, top shoe 6 and clamping screw 7, it is interior to be provided with female sliding block 3 wherein described bearing 1 is semiclosed hollow cavity, it is described
Linkage levelling screw 2 passes through the side wall of bearing 1, is threadedly secured on female sliding block 3, the clamping screw 7 passes through the He of top shoe 6
Female sliding block 3, it is threadedly secured to the bottom surface of bearing 1.
As shown in figure 3, being provided with two sub- sliding blocks 5 in described female sliding block 3, sub- sliding block 5 passes through the He of folding and unfolding screw rod 4
Two leads 8 are fixed in female sliding block 3, and the described both sides of folding and unfolding screw rod 4 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 inclined-plane that to be two opposite, inclined-plane and the top shoe 6 of female sliding block 3
Inclined-plane A is corresponding, 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 sliding block sliding back and forth relative to bearing 1, so that sliding block heads on top shoe about 6
It is mobile；Female sliding block 3 is connected with two sub- sliding blocks 5 by folding and unfolding screw rod 4, and the both sides of folding and unfolding screw rod 4 are reverse threads, realize two
Individual sub- sliding block 5 enters the purpose of female cavity of sliding block 3 or removal simultaneously, and female sliding block 3 and sub- sliding block 5 are two phases
Anti- inclined-plane, corresponding with A, B inclined-plane of top shoe, top shoe is made up of two inclined-planes A, the B intersected, sees Fig. 3, Fig. 4, Fig. 5；
The different phase of levelling gear work, contact of incline plane or the disengaging with female sliding block 3 and sub- sliding block 5 respectively of A inclined-planes, B inclined-planes；
When the A inclined-planes between female sliding block 3 and top shoe 6 take different angle with the B inclined-planes between sub- sliding block 5 and top shoe 6, i.e.,
It may be implemented in two grades of leveling precision during leveling.
When rising is adjusted, two sub- sliding blocks should be kept all to be adjusted into female sliding block by folding and unfolding screw rod
State in respective cavities, first rotates linkage levelling screw, moves forward female sliding block, now the inclined-plane and top shoe of female sliding block
A contact of incline plane, pass through female sliding block promote top shoe rise；When female sliding block has reached range, folding and unfolding spiral shell is adjusted
Bar makes two sub- sliding blocks be removed from the cavity of female sliding block, now the inclined-plane of sub- sliding block B inclined-planes corresponding with top shoe
Contact, linkage levelling screw is then rotated in the opposite direction, screw rod promotes female sliding block and two sub- sliding blocks to be moved rearwards together, now
The inclined-plane of female sliding block and the A inclined-planes of top shoe depart from, and sub- sliding block promotes top shoe to continue to rise.
The course of work that adjustment mechanism declines is opposite.
