Abstract
A vibration isolator relates to a vibration isolation device. Mainly be big for solving present coal breaker during operation vibration, easily cause the problem of damage to shock attenuation platform's spring and design. The damping oil tank comprises an outer tank body and an inner tank body; the outer box body is fixed on the lower base, damping oil is filled in the outer box body, and an opening is formed in the top of the outer box body; an outer cover is fixed at the upper end of the inner box body, the outer cover is fixed on the upper base, the lower end of the inner box body is of an open structure, and the lower part of the inner box body of the damping oil tank extends into the outer box body from an opening at the top of the outer box body; holes are respectively arranged on the lower base and the upper base on two sides of the damping oil tank, the holes of the upper base and the lower base are opposite, bolts are arranged in corresponding holes of each group of the upper base and the lower base, the upper ends of the bolts extend out of the holes of the upper base and are screwed with nuts, and the lower ends of the bolts extend out of the holes of the lower base and are screwed with nuts; the bolt is sleeved with a spring. The advantage is that the shock absorbing parts are not easy to damage.
Description
The technical field is as follows:
the utility model relates to a vibration isolation device, in particular to a vibration isolator applied to a damping platform of a coal breaker.
Background art:
the existing coal breaker damping platform comprises a bottom plate and a table top, wherein a coal dropping pipe extending downwards is fixed on the table top, and the coal dropping pipe is butted with a discharge hole of a coal breaker; the bottom plate upper surface is equipped with the link, and the mesa lower surface is equipped with the link, is equipped with the screw rod between two links, and screw rod outside cover has the spring, because the coal breaker during operation vibration is big, easily causes the damage to the spring, reduces the life of spring, and the spring damage still easily leads to the stationarity of shock attenuation platform poor.
The utility model content is as follows:
the utility model aims to solve the technical problem of providing the vibration isolator which has good damping effect and the damping parts are not easy to damage.
The above object is achieved by: the damping platform comprises a lower base and an upper base, wherein the lower base is fixed on a bottom plate of the damping platform, and the upper base is fixed on a table top of the damping platform; the damping oil tank comprises an outer tank body and an inner tank body; the outer box body is fixed on the lower base, damping oil is filled in the outer box body, and an opening is formed in the top of the outer box body; an outer cover is fixed at the upper end of the inner box body, the outer cover is fixed on the upper base, the lower end of the inner box body is of an open structure, and the lower part of the inner box body of the damping oil tank extends into the outer box body from an opening at the top of the outer box body; holes are respectively arranged on the lower base and the upper base on two sides of the damping oil tank, the holes of the upper base and the lower base are opposite, bolts are arranged in corresponding holes of each group of the upper base and the lower base, the upper ends of the bolts extend out of the holes of the upper base and are screwed with nuts, and the lower ends of the bolts extend out of the holes of the lower base and are screwed with nuts; a spring is sleeved outside the bolt between the upper base and the lower base; the upper end of the spring is propped against the upper base, and the lower end of the spring is propped against the lower base.
The utility model has the advantages that: when the damping platform is used, the upper base is fixed on the table top of the damping platform of the coal pulverizer, and the lower base is fixed on the bottom plate of the damping platform of the coal pulverizer. When the coal breaker is vibrated in operation, the damping oil pressure and the spring play a role in buffering, and the damping component is not easy to damage, and is safe and reliable. The device has simple structure and good vibration isolation effect.
Description of the drawings:
fig. 1 is a schematic structural view of the present invention.
The specific implementation mode is as follows:
the utility model is further illustrated with reference to fig. 1;
the damping platform comprises a lower base 1 and an upper base 2, wherein the lower base is fixed on a bottom plate of the damping platform, and the upper base is fixed on a table top of the damping platform; the damping oil tank comprises an outer box body 3 and an inner box body 4; the outer box body is fixed on the lower base, damping oil is filled in the outer box body, and an opening is formed in the top of the outer box body; an outer cover 5 is fixed at the upper end of the inner box body, the outer cover is fixed on the upper base, the lower end of the inner box body is of an open structure, and the lower part of the inner box body of the damping oil tank extends into the outer box body from an opening at the top of the outer box body; holes are respectively arranged on the lower base and the upper base on two sides of the damping oil tank, the holes of the upper base and the lower base are opposite, a bolt 6 is arranged in each group of corresponding holes of the upper base and the lower base, the upper end of the bolt extends out of the hole of the upper base and is screwed with a nut, and the lower end of the bolt extends out of the hole of the lower base and is screwed with a nut; a spring 7 is sleeved outside the bolt between the upper base and the lower base; the upper end of the spring is propped against the upper base, and the lower end of the spring is propped against the lower base.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
