Detailed description of the invention
Carry out clear complete description below with reference to the technical scheme of accompanying drawing to each embodiment of the utility model, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiment.Based on the embodiment in the utility model, other embodiments all that those of ordinary skill in the art obtain under the prerequisite not needing creative work, all in the scope that the utility model is protected.
Consider that in using at present large-tonnage to turn, flat hinge is turned limited, the problem that ball pivot processing is inconvenient, the utility model provides one and to turn the flat hinge of sphere.
Consider in conjunction with two kinds of hinge structural advantages, plane of rotation is set to sphere, contact concrete parts is set to plane, form sphere flat hinge structure.Flat hinge can be made by cast steel or plane steel plate respectively up and down, and upper flat hinge upper surface is convex spherical, and lower flat hinge upper surface is concave spherical surface, the design of sphere puts down hinge that Here it is.
Sphere of turning is equalled hinge and is comprised: upper flat hinge, lower flat hinge, and upper flat hinge, lower flat hinge are established up and down relatively, and bearing pin is through the center of the two; The soffit of upper flat hinge is convex spherical steel plate, and the upper surface of lower flat hinge is concave spherical surface steel plate, and convex spherical steel plate is identical with the radian of concave spherical surface steel plate, equal and opposite in direction; The upper flat upper surface of hinge and the soffit of lower flat hinge are parallel to each other, and are plane steel plate; The spherical radius of upper flat hinge is 0.5 ~ 6 times of planar diameter; The spherical radius of lower flat hinge is 0.5 ~ 6 times of planar diameter.
Upper flat hinge and lower flat hinge, the upper surface of the steel plate of upper flat hinge is plane steel plate, and soffit is convex spherical steel plate, and the upper surface of lower flat hinge is concave spherical surface steel plate, and soffit is plane steel plate.Steel plate structure is easy to process, can adopt integrated molding in some cases, and the two, through the central through hole of the two, couples together by bearing pin, can relatively rotate up and down between flat hinge.And the spherical radius of upper flat hinge is 0.5 ~ 6 times of planar diameter; The spherical radius of lower flat hinge is 0.5 ~ 6 times of planar diameter.Originally the flat hinge of sphere of turning is easy to process, applied widely, is especially applicable to the operation of turning compared with large-tonnage scope.
The multiple embodiment of following utilization is described in detail:
One is turned, and sphere is flat to be cut with scissors, as shown in Figure 1, 2, 3, be made up of upper flat hinge 3, lower flat hinge 4, the bottom of flat hinge 4 arranges support frame 7 down, and this support frame 7 suitably can adjust bearing height according to highly needing, and installs lower rotary table 6 around lower flat hinge 4 and support frame 7, rotating disk 1 is installed around upper flat hinge, upper flat hinge 3 and lower flat hinge about 4 are arranged, contact, arrange slide plate therebetween.Upper flat hinge 3, lower flat hinge about 4 are established relatively, and bearing pin 10 is through the center of the two; Upper flat hinge 3, lower flat hinge 4 arrange through hole at center, and bearing pin 10 is through through hole.In order to avoid shaking, and friction, arrange pipe box at through hole, bearing pin 10 is through pipe box.The soffit of upper flat hinge 3 is convex spherical steel plate 9, and the upper surface of lower flat hinge 4 is concave spherical surface steel plate 8, and convex spherical steel plate 9 is identical with the radian of concave spherical surface steel plate 8, equal and opposite in direction; To reach effect of fitting preferably, promote the stability of rotating, and rotate being uniformly distributed of shearing force.The upper upper surface of flat hinge 3 and the soffit of lower flat hinge 4 are parallel to each other, and are plane steel plate, and in order to contact concrete structure, in order to adapt to large-tonnage, large-sizedly turn, the spherical radius of upper flat hinge is 0.5 ~ 6 times of planar diameter; The spherical radius of lower flat hinge is 0.5 ~ 6 times of planar diameter.Adjusting range is large, and compliance of turning is stronger.
Based on the design of technique scheme, arrange skateboard between upper flat hinge 3 and lower flat hinge 4, skateboard embeds in upper flat hinge 3 or lower flat hinge 4.This slide plate can be ultra-high molecular weight polyethylene slide plate or modified Teflon slide plate.Slide plate can as a whole structure, also can be spliced for multiple sub-slide plate.Frictional force when slide plate can reduce upper flat hinge 3, lower flat hinge 4 relatively rotates.
Consider that sphere puts down the integral rigidity of hinge, state the upper surface of edge conjunction first steel pile casting 2, first steel pile casting 2 perpendicular to upper flat hinge 3 of the upper surface of flat hinge 3.
The workability of hinge is equalled, the plane steel plate of upper flat hinge 3 upper surface and the first steel pile casting 2 is one-body molded or welding in order to increase sphere.Wherein one-body moldedly can improve overall rigidity, when utilizing larger shearing force, sphere puts down the transmission of hinge internal forces, there will not be the sudden change of power, improves stability that large-tonnage turns, safety.And the technical examples of welding, comparatively speaking, more convenient sphere puts down transport and the in-site installation of hinge.
Similar to upper flat hinge 3, edge conjunction second steel pile casting 5, second steel pile casting 5 of the soffit of lower flat hinge 4 is perpendicular to the soffit of lower flat hinge 4.
Down flat hinge 4 soffit plane steel plate and the second steel pile casting 5 is one-body molded or welding.Wherein one-body moldedly can improve overall rigidity, when utilizing larger shearing force, sphere puts down the transmission of hinge internal forces, there will not be the sudden change of power, improves stability that large-tonnage turns, safety.
In order to better be connected with concrete, two plane steel plates of upper and lower position all arrange multiple WELDING STUDS 12 of identical number, and all WELDING STUDS 12 are uniform on plane steel plate.Arranging WELDING STUDS 12, effectively to strengthen flat hinge 4 up and down bonding with concrete, strengthens the globality of flat hinge of turning.
On the other hand, consider that sphere puts down the integral rigidity of hinge, two plane steel plates of upper and lower position all arrange multiple floors 11 of identical number, same distribution mode.
The distribution mode of floor 11 can adopt a lot of mode, and various ways can singlely exist, and also can multiplely combine.Such as: as shown in Figure 2, on each plane steel plate, floor 11 is outside radiant type distribution from the center of plane steel plate.Again such as: as shown in Figure 3, on each plane steel plate, the distribution in right-angled intersection formula of multiple floor 11.
The various embodiments that the utility model provides can combine as required in any way mutually, the technical scheme obtained by this combination, also in scope of the present utility model.
Obviously, when not departing from spirit and scope of the present utility model, those skilled in the art can carry out various change and modification to the utility model.If to change of the present utility model these and modification is within the scope of claim of the present utility model and equivalent thereof, then the utility model also will comprise these and change and modification.
