Embodiment
Fig. 2 is that the utility model wind-powered electricity generation gear case flexible pin shaft conical ring is measured the instrumentation plan with leveling tool, and Fig. 3 be that to use leveling tool structural representation, Fig. 4 be the cut-open view of the adjuster bar among Fig. 3 to the measurement of the utility model wind-powered electricity generation gear case flexible pin shaft conical ring.In conjunction with Fig. 2 to Fig. 4, the wind-powered electricity generation gear case flexible pin shaft conical ring that present embodiment provides is measured and is used leveling tool, comprising: horizontally disposed pressing plate 201, and pressing plate 201 centers offer the installation through hole 202 that is used to wear the planet bearing pin; Be set with at least three adjuster bars 203 along vertically extending respectively on pressing plate 201 and around through hole 202 is installed, at least three adjuster bars 203 all equate to the distance that through hole 202 centers are installed, and the distance of adjacent two adjuster bars 203 equates; The end of adjuster bar 203 is provided with the hold-down head 205 on the end face to be grinding 210 that is used to replace conical ring 213, and hold-down head 205 can be along adjuster bar 203 towards pressing plate 201 moves; Be arranged with an elastic component 204 on adjuster bar 203, the two ends of elastic component 204 are replaced respectively on pressing plate 201 and hold-down head 205.
Particularly, offer on this pressing plate 201 through hole 202 is installed, the size that the aperture of through hole 202 is installed can be the slightly larger in diameter than the pin 212a in the Assembly of pin 212, and wherein, Assembly of pin 212 is made up of pin 212a and axle 212b; Can wear at least three, the adjuster bar 203 that vertically extends around the through hole 202 installing, and at least three adjuster bars 203 lay respectively at each place, summit of same regular polygon, be arranged with elastic component 204 on the adjuster bar 203, the end of adjuster bar 203 is provided with hold-down head 205, and hold-down head 205 can be along adjuster bar 203 towards pressing plate 201 moves.
Preferably, this pressing plate 201 can be circular slab, at the edge of pressing plate 201 and offer groove 207 respectively between two adjacent adjuster bars 203.Present embodiment does not limit the shape of pressing plate 201.
Preferably, total number average of adjuster bar 203 and hold-down head 205 can be respectively four, and certainly, the sum of adjuster bar 203 and hold-down head 205 also can be set to three or five, and present embodiment is not as limit.
Further, can offer four tapped through holes on the pressing plate 201, the top of four adjuster bars 203 is bolted in respectively in four tapped through holes runs through pressing plate 201, and the nut on the top by the adjuster bar 203 that is spirally connected is fastened on adjuster bar 203 on the pressing plate 201.
Particularly, distance between adjacent two tapped through holes equates, thereby four adjuster bars 203 can distribute uniformly and be fixed on the pressing plate 201, and the set nut 206 by adjuster bar 203 tops that are spirally connected, and make adjuster bar 203 more fastening being fixed on the pressing plate 201.Present embodiment does not limit the mode of fixedlying connected between adjuster bar 203 and the pressing plate 201, in other embodiments, for example, can be by interference fit adjuster bar 203 and pressing plate 201 to be assembled together.
Preferably, above-mentioned elastic component 204 can be compression spring.Owing to after set nut 206 lockings, can make pressing plate 201 and convex annular appear to fit closely, and then make compression spring can be in compressive state, but not be compressed to compression limit with pressing plate 201 to pressing down at the beginning.Because an end of compression spring withstands on the pressing plate 201, the other end withstands on the hold-down head 205, when compression spring is in compressive state, can gives 205 1 downward power of hold-down head, thereby hold-down head 205 can be replaced on the end face to be grinding 210 of conical ring 213.
The wind-powered electricity generation gear case flexible pin shaft conical ring 213 that present embodiment provides is measured with leveling tool when conical ring 213 is carried out leveling, earlier conical ring 213 covers are set on the Assembly of pin 212, then wind-powered electricity generation gear case flexible pin shaft conical ring 213 is measured and be set on the Assembly of pin 212 with the leveling tool cover, the hold-down head 205 of adjuster bar 203 ends can be replaced on the end face to be grinding 210 of conical ring 213, because adjuster bar 203 evenly distributes, and the elastic component 204 that is set on the adjuster bar 203 applies a downward power can for hold-down head 205, thereby can make conical ring 213 be in level substantially, by reading the registration that is fixed on the dial gauge 208 in two relative on pressing plate 201 edges grooves 207, can judge further whether conical ring 213 is in level, if conical ring 213 is not in level, need finely tune conical ring 213, with higher one side tool using clouting gently, read the registration of two relative dial gauges 208 again, be in level until conical ring 213.
From the above, the wind-powered electricity generation gear case flexible pin shaft conical ring that present embodiment provides is measured and is used leveling tool, by the setting of hold-down head and elastic component on adjuster bar and the adjuster bar, guaranteed the accurate, reliable of measurement result, and simple in structure, easy operating has improved surveying work efficient.
Further, above-mentioned respective slot 207 places also are provided with and are used to measure the dial gauge 208 of groove 207 positions to the vertical range of the end face to be grinding 210 of conical ring 213.Alternatively, dial gauge 208 is by in the groove 207 on the edge that connects fixture block 209 and be fixed on pressing plate 201.
Particularly, dial gauge 208 is used to make things convenient for the staff to observe conical ring 213 to be measured whether to be in level.The staff is before measuring conical ring 213, and the registration by reading two relative dial gauges 208 is also calculated difference between these two registrations, if this difference smaller or equal to 0.05mm, illustrates that then conical ring 213 is horizontal, and meets design requirement; If this difference greater than 0.05mm, illustrates that conical ring 213 is not horizontal, for meeting design requirement, need finely tune, so that conical ring 213 is in level.In the present embodiment, if the curtailment of the sounding rod of dial gauge 208 is so that the end face to be grinding 210 of measuring head contact conical ring 213, can also between the end face to be grinding 210 of the measuring head of dial gauge 208 and conical ring 213, place four contour posts 211, make the measuring head of dial gauge 208 be against the upper surface of contour post 211, thereby shorten the distance between the measuring head of the end face to be grinding 210 of conical ring 213 and dial gauge 208.
It should be noted that at last: above each embodiment only in order to the explanation the technical solution of the utility model, is not intended to limit; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
