Description
Technical field
The present invention relates to a kind of method and structure for improving arc door branch hinge installation accuracy, belong to Hydraulic and Hydro-Power Engineering metal knot
Structure technical field.
Background technology
For gates of segmental shape, branch hinge is its rotating part, if operation is not smooth, easily induces engineering accident, is related to arc
The safety of gate operation.Support hinge device generally use relative opening two sets of modes of center symmetric setting, because its two hinges with one heart can
Rotate, therefore the required precision installed to it is higher, the concentricity requirement of especially two hinges is higher, but prior art is to prop up
Support hinge device is fixed thereon by free bearing plate after installing, and therefore, the assembly precision of support hinge device depends on branch free bearing plate
Installation accuracy, and the concentric shafts pattern that branch hinge uses at present in the case where branch free bearing plate installation accuracy does not reach requirement condition substantially without
Method realizes required precision by adjusting branch hinge, and branch hinge bottom is reinstalled according to branch free bearing plate second stage concrete mode is cut
Plate, then difficulty is very big, and has a strong impact on the installation progress of gates of segmental shape, and the power benefit in power station can be caused to be damaged, so existing
Have that technology is still not perfect enough, up for further improving.
The content of the invention
It is an object of the present invention to provide a kind of method and structure for improving arc door branch hinge installation accuracy, with branch free bearing
In the case of plate installation accuracy does not reach requirement, turn to it by adjusting eccentric shaft and meet required precision, it is existing so as to overcome
The deficiency of technology.
The technical proposal of the invention is realized in this way:
Hinge is hinged on fixed hinge by a kind of method of raising arc door branch hinge installation accuracy of the present invention, this method using eccentric shaft
On seat, when the first dress size of hinge is unsatisfactory for design requirement, make hinge in the extent of the error of eccentric shaft by rotation eccentric axis
Inside it is adjusted up and down, until the installation dimension of hinge meets design requirement;Then by the only not rounded borehole jack on axle plectane
It axle plectane will be only fixedly connected on the non-circular bosses of eccentric shaft one end, and with screw with fixed hinged seat, and prevent eccentric shaft from continuing
Rotating makes hinge deviate the installation dimension adjusted.
In the foregoing method for improving arc door branch hinge installation accuracy, the only axle plectane is provided with arc slotted hole, screw set
It is threadedly coupled after upper gasket through arc slotted hole with the screwed hole on fixed hinged seat;When the installation dimension of hinge is adjusted to satisfaction
After design requirement, packing ring and only axle plectane are permanently fixed by the way of three face weld all arounds, prevent eccentric shaft in fixed hinged seat
Rotated in free bearing hole.
A kind of structure of the raising arc door branch hinge installation accuracy of the invention formed according to the above method, including fixed hinge
Seat, fixed hinged seat are hinged through eccentric shaft and hinge;Eccentric shaft one end is provided with non-circular bosses, and only axle plectane is cased with non-circular bosses,
Only axle plectane is fixedly connected through screw with fixed hinged seat.

Middle diameter segment, small middle diameter segment and reduced diameter section;Enlarged diameter section and reduced diameter section are coaxial;Big-and-middle diameter segment, middle diameter segment and small
Middle diameter segment is coaxial;The shaft shoulder and adjacent segment arc transition between each section.
In aforementioned structure, free bearing hole, one of free bearing hole aperture are respectively equipped with two otic placodes of the fixed hinged seat
Corresponding with the enlarged diameter section diameter of eccentric shaft, another free bearing hole aperture is corresponding with the reduced diameter section diameter of eccentric shaft;Eccentric shaft
Enlarged diameter section and the axis of reduced diameter section overlapped with two free bearing axially bored lines.
In aforementioned structure, the hanger of the hinge is provided with pan, and pan is through straight in oscillating bearing and eccentric shaft
Footpath section connection;Oscillating bearing both sides are provided with bearing cap, and bearing cap is fixedly connected through screw with the hanger of hinge;Bearing cap and bias
Sleeve is provided between the reduced diameter section of axle;Oscillating bearing through the shaft shoulder between the middle diameter segment on eccentric shaft and big-and-middle diameter segment and
The sleeve axially position of reduced diameter section;The hinge hole axle of big-and-middle diameter segment, the axis of middle diameter segment and small middle diameter segment and hanger
Line overlaps;Distance between axles between hinge axially bored line and free bearing axially bored line is 5~100mm.
By adopting the above-described technical solution, the present invention is compared with prior art, the present invention has the advantages that:1、
The hinge of fixed hinged seat uses eccentric shaft, in the case of fixed hinged seat installation accuracy does not reach requirement, make by adjusting eccentric shaft
Its rotation can meet required precision, effectively reduce the installation difficulty of fixed hinged seat, and precision can be adjusted artificially, substantially increase solid
Determine the installation accuracy of free bearing;2nd, the end face of the enlarged diameter section of eccentric shaft uses quadrilateral structure of two opposite side for circular arc, makes
When only in the lateral symmetry cutting tip size in outer end, more traditional polygon or fluting pattern processing technology are simple, are easy to
Make;3rd, it is corresponding to the non-circular bosses appearance and size of eccentric shaft enlarged diameter section end face using non-circular hole after eccentric axial adjustment positioning and
Bigger stops the insertion of axle plectane and is fixed by screw and packing ring, and screw bottom sets ring-type or square packing ring, only axle plectane
The uniform arc slotted hole of ring-type is set, and when arc slotted hole meets the maximum adjustment displacement of eccentric shaft, the screw of fixed hinge exists
Ensure that screw can be fastened thereon in arc slotted hole, the screwed hole on fixed hinged seat can make in factory, match somebody with somebody without scene
Auger shell pit, installation are very convenient;4th, the not rounded boss height of the enlarged diameter section end face of eccentric shaft is slightly larger than enlarged diameter section solid
Determine the protruded length of free bearing, only axle plectane sets non-circular hole, non-circular hole profile and the non-circular bosses of eccentric shaft enlarged diameter section outer end
Appearance and size is corresponding and size is bigger, is easy to only on axle plectane insertion eccentric shaft;5th, packing ring is adopted with only axle plectane after screw fastening
Reach permanent positioning with three face weld all arounds to fix;6th, reduced diameter section outer end rounding, the equal chamfering in hinge axis hole both sides, is easy to wear axle;7、
Eccentric shaft sets the shaft shoulder to be easy to oscillating bearing to position, and it is spacing that oscillating bearing sets sleeve to be easy to.
