Further, it is provided with high-pressure oil duct and is communicated in described oil cylinder for vibro-damping mount described in jacking in ground or floor；
Further, make vibro-damping mount can arrange by the way of one-way movement straight up by non-return mechanism between described vibro-damping mount and oil cylinder inner wall；
Further, described concrete slab there are embedded bar sleeve, pre-buried channel-section steel and pre-buried template supporting parts by reinforcing bar connection；
Further, gap between described floating plate and ground or floor is provided with damping wheel, described damping wheel includes that the fixing rotating shaft of the rubber gear coordinated with the tooth bar being arranged at floating plate bottom surface and rubber gear and rotatable sealing are coated at the barrel-type casing of rotating shaft, the rotating shaft shaft part being positioned at described barrel-type casing is fixed with gear piece, described cylinder outer race is filled with magnetic flow liquid, is wound with induction coil outside barrel-type casing.
The invention has the beneficial effects as follows: the floating plate vibration absorber of the present invention, supported by vibration isolation unit between floating plate and floor or ground, make to exist between floating plate and floor certain interval, when floating plate vertically forced vibration, vibration is absorbed by the spring in vibration isolation unit and antivibrator, on the other hand, the horizontal vibration of floating plate is absorbed by the rubber between adjacent floating plate, vibration is avoided to drive to ground or floor, additionally, the height of the vibro-damping mount in vibration isolation unit realizes regulation by hydraulic system, and then the gap length formed between floating plate and floor or ground is adjusted.
Accompanying drawing explanation
The invention will be further described with embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of the vibration isolation unit of the present invention；
Fig. 3 is the structural representation of the damping force of the present invention.
Detailed description of the invention
Fig. 1 is the structural representation of the present invention, as shown in the figure, floating plate 5 vibration absorber of the present embodiment, including multiple floating plates 5, rubber damping band 11 and multiple vibration isolation unit 10, described floating plate 5 supports make to be formed between floating plate 5 and floor 6 or ground space by being positioned over floor 6 or ground vibration isolation unit 10, and described rubber damping band 11 is arranged between adjacent floating plate 5；Described vibration isolation unit 10 includes the oil cylinder 8 being fixed on ground or floor 6, as the piston of oil cylinder 8 be arranged at the vibro-damping mount in oil cylinder 8, the spring being arranged in vibro-damping mount, by described spring-supported gripper shoe 2, described floating plate 5 is concrete slab and is prefabricated with up big and down small shoulder hole 4, described vibration isolation unit 10 is positioned at described shoulder hole 4, the step of described shoulder hole 4 is fixed with jacking feature board 3 and this jacking feature board 3 is supported by the location bar 1 being fixed in gripper shoe 2；Supported by vibration isolation unit 10 between floating plate 5 and floor 6 or ground, make to there is certain interval between floating plate 5 and floor 6, when floating plate 5 vertically forced vibration, vibration is absorbed by the spring in vibration isolation unit 10 and antivibrator, on the other hand, the horizontal vibration of floating plate 5 is absorbed by the rubber between adjacent floating plate 5, vibration is avoided to drive to ground or floor 6, additionally, the height of the vibro-damping mount in vibration isolation unit 10 realizes regulation by hydraulic system, and then is adjusted the gap length formed between floating plate 5 and floor 6 or ground.
In the present embodiment, it is provided with high-pressure oil duct 7 in ground or floor 6 and is communicated in described oil cylinder 8 for vibro-damping mount described in jacking, high-pressure oil duct 7 is embedded in ground or floor 6, can effectively simplify the structure of this device, realize connecting and sealing by a connecting tube between high-pressure oil duct 7 with oil cylinder 8, when needs jacking floating plate 5, fluid can be injected in oil cylinder 8 by high-pressure oil pipe and make vibration isolating substrate upwards jack-up.
