Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Embodiment
See Fig. 1, a kind of paralleling mechanism vibration isolation and displacement protecting device comprise equipment mountion plate 1, carrier connecting platform 2 and two groups of movable support mechanisms; Equipment mountion plate 1 and carrier connecting platform 2 are rectangular platform, and parallel up and down; Often organize movable support mechanism and comprise the first identical shaft-like mechanism 4 of shaft-like mechanism 3, second of structure, the 3rd shaft-like mechanism 5 and the 4th shaft-like mechanism 6, every only shaft-like mechanism comprises Hooke's hinge, spherical hinge and spring damping and vibration isolating device, and two groups of movable support mechanism symmetries connect between equipment mountion plate 1 and carrier connecting platform 2.
See Fig. 2 and Fig. 3, the Hooke's hinge in shaft-like mechanism is made up of base 7, hinge pin 8 and the seat of honour 9; Spherical hinge is connected to form by ball pivot 15 and ball seat 16; Spring damping and vibration isolating device is made up of outer sleeve 11, damping spring 12 and piston rod 13.The seat of honour 9 of Hooke's hinge is connected to outer sleeve 11 by the first adapter ring 10, and piston rod 13 is connected to one end of the second adapter ring 14, and the other end of the second adapter ring 14 is connected to ball pivot 15; During use, the base 7 of Hooke's hinge is connected to carrier connecting platform 2, and ball seat 16 is connected to equipment mountion plate 1.
See Fig. 1, Fig. 4 and Fig. 5, the first shaft-like mechanism 3 of one group of movable support mechanism in parallel brace shape, lays respectively at the both sides of equipment mountion plate 1 and carrier connecting platform 2 one end with the 4th shaft-like mechanism 6; The base of the first shaft-like mechanism 3 and the base of the 4th shaft-like mechanism 6 respectively connected the both sides of carrier connecting platform 2 one end end face, and the ball seat of the first shaft-like mechanism 3 and the ball seat of the 4th shaft-like mechanism 6 respectively connected the both sides being positioned at bottom surface, equipment mountion plate 1 one end; Second shaft-like mechanism 4 and the 3rd shaft-like mechanism 5, in man type, are all positioned at the end face of equipment mountion plate 1 and carrier connecting platform 2 one end; The base of the second shaft-like mechanism 4 and the base of the 3rd shaft-like mechanism 5 respectively connected the both sides of carrier connecting platform 2 one end end face, and the ball seat of the second shaft-like mechanism 4 and the ball seat of the 3rd shaft-like mechanism 5 respectively connected the middle part being positioned at bottom surface, equipment mountion plate 1 one end.Four structures identical shaft-like mechanism symmetry of another group movable support mechanism is installed between the other end of equipment mountion plate 1 and carrier connecting platform 2.
Equipment mountion plate 1 is the platform installed and need protected equipment or instrument, in some cases, can not need platform, is directly installed on equipment by ball pivot.
Carrier connecting platform 2 is the basis of installing whole device, and Hooke's hinge is directly installed on basis, no longer arranges all the other platforms, and the rectangular area of eight Hooke's hinge line formation is virtual carrier connecting platform.
Spherical hinge is a kind of hinge providing three rotational freedoms; Hooke's hinge provides two rotational freedoms; The bar of spring damping and vibration isolating device is used for the vibration of offsetting to come up from the transmission of carrier connecting platform and displacement; In as installed process, the exchange that the position of Hooke's hinge and ball pivot can be paired, only need ensure that support system two ends are respectively a ball pivot and a Hooke's hinge.If must replace ball pivot with two Hooke's hinges, then must ensure that the piston rod 13 of Fig. 2 and Fig. 3 medi-spring damping shock absorber and outer sleeve 11 can form cylindric pair instead of sliding pair, now the degrees of freedom of whole system still meets the demands.
When carrier connecting platform 2 occurs in vibration, vibration needs to be transmitted by group movable support mechanism of two between carrier connecting platform 2 and equipment mountion plate 1; But, due to the existence of the spring damping and vibration isolating device in two groups of movable support mechanisms, vibration was just weakened before being delivered to equipment mountion plate 1, thus serves vibration isolation effect.Because equipment mountion plate 1, carrier connecting platform 2 and support system are not rigidly connected, by the combination of the relative movement of top and the bottom in Hooke's hinge, spherical hinge and spring damping and vibration isolating device, equipment mountion plate 1 can be moved by opposite carrier connecting platform on six-degree-of-freedom direction, and this just makes whole vibrating isolation system to carry out multidimensional vibration isolation.
When carrier connecting platform 2(i.e. basis) upper when producing local deformation, if local deformation does not have influence on the mounting point of Hooke's hinge on carrier connecting platform 2, be then out of shape and equipment mountion plate 1 is not had an impact completely.If local deformation has just in time had influence on one or two in eight mounting points; spring in spring damping and vibration isolating device in the support system be then now connected with this Hooke's hinge also can produce distortion; and other springs also can produce distortion; just front spring mode of texturing is contrary with it for mode of texturing; (as platform local crowning; then this spring is compressed, and other springs are stretched) thus offset the impact that a part of platform is out of shape generation, and then the attitude of equipment mountion plate 1 is protected.
The present embodiment is applicable to the isolating technique of airborne equipment, and particularly isolation is when taking off and land, and is delivered to multi-dimensional vibration airborne equipment and machinery space bulkhead deformation effect, ensure that airborne equipment attitude stabilization and usability from fuselage wall.
