Description
Technical field
The present invention relates to a kind of vibration isolator, be particularly useful for the vibration isolation of transformer, also can be applied to other needs vibration isolation and requires to control on the machine of height of C.G. or equipment.
Background technique
Some main equipments in the course of the work, himself can be produced vibration and have an impact to surrounding, thus needing to be installed by isolation mounting.For transformer: transformer is usually used in the power supply system such as commercial complex, residential quarter, be generally arranged in the bottom of tall building or the switch board room of basement.The vibration that transformer causes is delivered on building by building structure, forms the construct noise being difficult to administer and pollutes, and vibration isolator then can the vibration passing of effective blocking transformer.
As visible in accompanying drawing 1, the vibration isolator load bearing support face used at present is positioned at the upper end of stage clip 3, the height in load bearing support face is greater than the height (generally at more than 150mm) of stage clip 3, so after installation vibration isolator equipment 10(as transformer) center of gravity be also enhanced thereupon, although thus cause the vibration passing of equipment Vertical direction after vibration isolation to reduce, but swing in the horizontal direction can aggravate on the contrary, and vibration isolating effect is undesirable.Simultaneously due to the swing of substantially horizontal, cause the bad stability of equipment, the fixture working procedure such as transformer lead are medium-term and long-term is subject to horizontal hunting interference, can reduce the life-span of transformer lead, even can bring potential safety hazard.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of cantilever type damp vibration isolator, effectively can improve vibration isolating effect, improves equipment working stability.
For achieving the above object, cantilever type damp vibration isolator of the present invention has following structure characteristic: the support bearing plate comprising " Z " shape, and described support bearing plate comprises a supporting surface, and supporting surface one end is bent with cantilever, and cantilevered distal end is bent with weight-bearing surface; Also comprise the base be arranged on below supporting surface, be provided with at least one group of stage clip of Bolt to position between base and supporting surface near one end of cantilever, the other end is provided with at least one group of extension spring.
The upper-end surface of weight-bearing surface is provided with load-bearing rubber pad, the lower end surface of base is provided with base rubber pad.
After have employed technique scheme, cantilever type damp vibration isolator of the present invention, is one group with four and is arranged in four footing of equipment symmetrically and carries out support by the weight-bearing surface of each vibration isolator to equipment, and stage clip and extension spring can vibration isolation in the vertical direction effectively; Owing to reducing the height of weight-bearing surface, thus substantially horizontal swing can be effectively reduced, improve equipment working stability.Rubber pad can play damping, vibration isolation effect and stabilization further.
Between described base and supporting surface, the arranged outside of extension spring has the push rod be with and damaged mouth in advance.Adopting the object of this structure, is facilitate equipment to install.Equipment is not before installing, and due to non-loaded on weight-bearing surface, further in the one end supporting bearing plate and base by extension spring, and the other end tilts.After adopting said structure, due to the effect of push rod, can stop and tilt impact.After equipment installation, mouth rapid damage push rod can be damaged by pre-, make the present invention enter normal working.

Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5 are visible, cantilever type damp vibration isolator of the present invention, comprises the support bearing plate 1 of " Z " shape, and described support bearing plate 1 comprises a supporting surface 11, supporting surface 11 one end is bent with cantilever 12, and cantilever 12 end is bent with weight-bearing surface 13; Also comprise the base 7 be arranged on below supporting surface 11, be provided with at least one group of stage clip 3 that bolt 6 is located near one end of cantilever 12 between base 7 and supporting surface 11, the other end is provided with at least one group of extension spring 2, base 7 lower end surface is provided with base rubber pad 5, and the upper-end surface of weight-bearing surface 13 is provided with load-bearing rubber pad 4.
This base rubber pad 5, load-bearing rubber pad 4 can be fixed in a variety of forms, fix preferably by vulcanization, thus improve equipment bonding tightness, improve vibration isolating effect and damping further.
As shown in Figure 5, during work, cantilever type damp vibration isolator of the present invention is one group with four and is arranged in four footing of equipment symmetrically and carries out support by the weight-bearing surface of each vibration isolator to equipment, and equipment such as transformer 10 grade is fixed on the weight-bearing surface 13 of four load-bearing assemblies.Because cantilever 12 is to downward-extension, reduce load height, thus can effectively reduce substantially horizontal and swing.The present invention is not only applicable to the vibration isolation of transformer, is applicable to the vibration isolation of miscellaneous equipment yet.
Stage clip 3 is main bodys of load-bearing, extension spring 2, stage clip 3, weight-bearing surface 13 and on load form a lever construction, it and base rubber pad 5, load-bearing rubber pad 4 both effectively also can possess damping function while load-bearing after combining.
As shown in Figure 4, the end of extension spring 2 is arranged through extension spring hook 20 and is connected with the hanging nose 70 that base 7 is arranged, this structure, and the sphere of activities of extension spring 2 is larger, can play cushioning effect better.
When carrying out equipment and installing, the spacing between offside vibration isolator can be adjusted, make the cantilever 12 of surrounding directly approach equipment to install, make cantilever 12 while taking on the arm of force, lateral support effect can also be played, thus substantially horizontal swing can be effectively reduced better, improve equipment working stability.
Equipment is not before installing, and due to non-loaded on weight-bearing surface 13, extension spring 2 furthers supporting bearing plate 1 one end with base 7, and the other end tilts.For this reason, cantilever type damp vibration isolator of the present invention, further between described base 7 and supporting surface 11, the arranged outside of extension spring 2 has the push rod 8 be with and damaged mouth 80 in advance.
After adopting said structure, due to the effect of push rod 8, can stop and tilt impact.After equipment installation, mouth 80 rapid damage push rod 8 can be damaged by pre-, make the present invention enter normal working.This push rod 8 can use cast iron quality, cheap and be easy to manufacture and be easy to fracture.
