Description

Coal breaker damping platform
The technical field is as follows:
the utility model relates to a damping platform for placing 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 upper surface of the bottom plate is provided with a connecting frame, the lower surface of the table top is provided with a connecting frame, a screw rod is arranged between the two connecting frames, a spring is sleeved outside the screw rod, and a circle of canvas is wound outside the coal dropping pipe. Because the coal breaker during operation vibration is big, easily causes the damage to spring and canvas, the spring damage can lead to the shock attenuation platform stationarity poor, and the canvas damages and can reduce sealing performance, leads to the dust to leak outward, the polluted environment.
The utility model content is as follows:
the utility model aims to solve the technical problem of providing a coal breaker damping platform which is good in damping effect, not easy to damage damping parts and good in sealing performance.
The above object is achieved by: the coal dropping device comprises a bottom plate and a table top, wherein a coal dropping pipe extending downwards is arranged on the table top, and a plurality of vibration isolators are arranged between the bottom plate and the table top; the bottom plate outside the lower end of the coal dropping pipe is provided with an annular groove, sponge rubber is fixed in the annular groove, a sealing cover extending downwards is fixed on the table top outside the upper end of the coal dropping pipe, and the lower end of the sealing cover is in contact with the sponge rubber in the annular groove.
The vibration isolator comprises a lower base and an upper base, the lower base is fixed on the bottom plate, and the upper base is fixed on the table top; 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: because a plurality of vibration isolators are arranged between the bottom plate and the table board, when the coal breaker vibrates in working, the damping oil pressure and the spring play a role in buffering, and the coal breaker is safe and reliable. Because the annular groove is formed in the bottom plate, the sponge rubber is installed in the annular groove, the sealing cover is arranged on the table top and contacts with the sponge rubber, the sealing effect can be guaranteed, the damage to the sealing cover caused by vibration of the coal pulverizer can be reduced, and the service life is prolonged.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is an enlarged schematic view of the structure at A in FIG. 1;
fig. 3 is an enlarged schematic view of the structure of the vibration isolator according to the present invention.
The specific implementation mode is as follows:
the utility model is further illustrated with reference to fig. 1-3;
the coal dropping device comprises a bottom plate 1 and a table top 2, wherein a coal dropping pipe 3 extending downwards is arranged on the table top, and a plurality of vibration isolators 4 are arranged between the bottom plate and the table top; an annular groove 5 is formed in the bottom plate on the outer side of the lower end of the coal dropping pipe, sponge rubber 6 is fixed in the annular groove, a sealing cover 7 extending downwards is fixed on the table top on the outer side of the upper end of the coal dropping pipe, and the lower end of the sealing cover is in contact with the sponge rubber in the annular groove.
The vibration isolator 4 comprises a lower base 4-1 and an upper base 4-2, wherein the lower base is fixed on the bottom plate, and the upper base is fixed on the table top; the damping oil tank comprises an outer box body 4-3 and an inner box body 4-4; 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 4-5 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, bolts 4-6 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 4-7 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.
