Detailed description of the invention
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As shown in Fig. 1~Fig. 6, the present embodiment includes 4 flower basket bolts, straight in the plane of the upper side of lower mounting base 20 In angle coordinate system, first flower basket bolt 1 one end is along the gaily decorated basket spiral shell of X-direction with guide pillar 30 top being positioned on the left of center drum 40 Bolt supports that seat 31 is fixing to be connected, and second flower basket bolt 2 one end is along the flower on guide pillar 30 top on the right side of Y direction and center drum 40 Basket bolt support seat 31 is fixing to be connected;3rd flower basket bolt 3 one end and the 4th flower basket bolt 4 one end are respectively along X-direction and Y-axis Direction is fixing with two mutually perpendicular installed surfaces of the locating dowel 51 being fixed on bottom hoist cylinder 50 to be connected, each flower basket bolt The other end is separately fixed on inside the hull 100 of correspondence position.So, the guide pillar 30 in left side, the guide pillar 30 on right side and lifting Oil cylinder 50 obtains Primary Location.
Low level stroke, middle position stroke and three length of high-order stroke that center drum lifts are driven according to hoist cylinder 50 Stroke stage of being incremented by, it is respectively provided with the low level stroke of corresponding a length of 400mm and props up stay tube 5, a length of 1450mm Middle position stroke props up the high-order stroke of stay tube 6 and a length of 2500mm and props up stay tube 7.Low level stroke props up stay tube 5, middle position stroke props up stay tube 6 and high-order stroke prop up between the two ends that stay tube 7 is arranged in pairs in upper guide plate 10 and lower mounting base 20 respectively, and be positioned at correspondence Inside guide pillar 30.The center drum 40 at differing heights is lifted, it is simple to carry out the measurement of perpendicularity for supporting.
Adjustment process of the present utility model is as follows:
As shown in Fig. 1, Fig. 4, Fig. 5 and Fig. 6,1) two amesdials 80 of installation on lower mounting base 20, wherein first Amesdial base position 81 is fixed between guide pillar 30 and center drum 40, and is positioned on lower mounting base longitudinal centre line, thousand points Table gauge head 82 is resisted against on center drum 40 outer peripheral face, and amesdial gauge head 82 axis points to center drum 40 axle center.Second thousand Table base 81 is divided to be fixed on lower mounting base 20 cross central line, second amesdial gauge head 82 axis and first amesdial The angle of gauge head 82 axis is 90 °, and each amesdial 80 arranges zero-bit.
2) hoist cylinder piston rod 501 rises, under the guide pillar 30 making upper guide plate 10 drive center drum 40 at two ends guides Rise, when upper guide plate 10 rises to prop up with low level stroke height corresponding to stay tube 5, two low level strokes are propped up stay tube 5 and puts into Between upper guide plate 10 and lower mounting base 20, vertical support lives in guide plate 10, and two low level strokes prop up stay tube 5 and lay respectively at center Between cylinder 40 both sides and two guide pillars 30.
3) first flower basket bolt the 1, second flower basket bolt the 2, the 3rd flower basket bolt 3 and the 4th flower basket bolt 4 are regulated respectively Length, thus two guide pillars 30 of regulation and the perpendicularity of hoist cylinder 50 respectively;Read the measured value of amesdial 80 and note hanging down Straight degree error amount is forward or negative sense, again regulates the length of four flower basket bolts, makes in the measurement of two amesdials 80 Heart cylinder 40 error of perpendicularity value the most in allowed limits and keeps constant.
4) as in figure 2 it is shown, hoist cylinder piston rod 501 continues to rise, remove two low level strokes and prop up stay tube 5, lead upper When plate 10 rises to prop up height corresponding to stay tube 6 with middle position stroke, position stroke in two is propped up stay tube 6 put into upper guide plate 10 and under Between mounting base 20, vertical support lives in guide plate 10, in two position stroke prop up stay tube 6 lay respectively at center drum 40 both sides and Between two guide pillars 30;Repeat the process of step 3), make the measured value of two amesdials 80 all in the range of permissible value and protect Hold constant.
5) as it is shown on figure 3, hoist cylinder piston rod 501 continues to rise, in removing two, position stroke props up stay tube 6;Lead upper When plate 10 rises to prop up height corresponding to stay tube 7 with high-order stroke, two high-order strokes are propped up stay tube 7 put into upper guide plate 10 and under Between mounting base 20, vertical support lives in guide plate 10, two high-order strokes prop up stay tube 7 lay respectively at center drum 40 both sides and Between two guide pillars 30;Repeat the process of step 3), make the measured value of two amesdials 80 all in the range of permissible value and protect Hold constant.
6) hoist cylinder piston rod 501 trace rises, and removes two high-order strokes and props up stay tube 7, changes position stroke in two Prop up stay tube 6;Hoist cylinder piston rod 501 drops to upper guide plate 10 and is supported on position stroke in two and props up on stay tube 6, repeats step 3) Process, make the measured value of two amesdials 80 all in the range of permissible value and keep constant;
7) hoist cylinder piston rod 501 trace rises, and in removing two, position stroke props up stay tube 6, changes two low level strokes Prop up stay tube 5;Hoist cylinder piston rod 501 continues to drop to upper guide plate 10 and is supported on two low level strokes and props up on stay tube 5, repeats step Rapid 3) process, makes the measured value of two amesdials 80 all in the range of permissible value and keep constant.
8) step 2 is repeated several times) to the process of step 7) so that hoist cylinder piston rod 501 is led two guide pillars 30 Downwards, driving center drum 40 and propeller 70 smoothly vertical lift by upper guide plate 10, during lifting, center drum 40 hangs down Straight degree error amount and keeps constant in the range of permissible value, and the centering completing propeller lifting and guiding device adjusts.
In addition to the implementation, this utility model can also have other embodiments, all employing equivalents or equivalence to become Change the technical scheme of formation, all fall within the protection domain of this utility model requirement.
