Abstract
The invention discloses the flexible steel bushing rubber ring of sealing, the rubber ring includes rubber ring, the mesh steel wire of individual layer 6, and the mesh steel wire of individual layer 6 is arranged on the centre position of rubber ring；By being constructed to rubber ring own material, it is additionally arranged after the mesh steel wire of individual layer 6, flexible joint ring intensity can be effectively improved.The flexible steel bushing rubber ring of sealing, sets the mesh steel wire of individual layer 6, the structure increases the bulk strength of rubber ring inside rubber ring, improves the stress performance of rubber ring when flexible steel bushing shield is received, improves its reusability.The intensity of rubber ring can ensure that the globality of flexible steel bushing in the flexible steel bushing of increase sealing, extend the service life of steel bushing, and more can guarantee that shield receives safety.The degree of safety that flexible steel bushing is received not only is improved, while extending the service life of rubber ring.
Description
Technical field
The invention discloses the flexible steel bushing rubber ring of one kind sealing, belong to the interval field of engineering technology of shield, especially
It is related to a kind of flexible steel bushing of sealing of shield reception.
Background technology
At present, the domestic flexible rubber ring material used is ethylene propylene diene rubber, and its insufficient strength, easily by drawing crack, is present
Serious potential safety hazard.For this, project management department works out new rubber ring material composition, and rubber is increased from the angle of mechanics stress
The intensity of glue ring.This method from the angle of science, take shield is received when rubber ring carry out force analysis, to flexible steel bushing
Integrity be controlled.The degree of safety that flexible steel bushing is received is not only increased, while extending the service life of rubber ring.
In the engineering of shield interval, developed according to the flexible steel bushing raising rubber ring intensity of sealing for demand and improve rubber ring structure
Make.Received for shield with the flexible steel bushing of sealing, how to ensure the integrity of rubber ring to ensure the security of shield reception
It is weight difficult point content, directly determines safety of production etc..
The content of the invention
It is an object of the invention to provide a kind of flexible steel bushing rubber ring of sealing, it is directed to rubber ring insufficient strength shadow
The weakness that flexibility steel bushing shield receives safety is rung, a kind of new rubber ring tectonic sieving scheme is devised.
The flexible steel bushing rubber ring of sealing, the rubber ring includes rubber ring 1, the mesh steel wire 2 of individual layer 6, the mesh steel wire of individual layer 6
Net 2 is arranged on the centre position of rubber ring 1；Rubber ring 1 takes the shape of the letter U arrangement, and the inner side of rubber ring 1 is provided with steel loop plate a4, rubber ring 1
Outside be provided with steel loop plate b5, steel loop plate b5 thickness is more than steel loop plate a4 thickness；Steel loop plate a4, steel loop plate b5 and rubber ring
Connected between 1 three by bolt 3.
By being constructed to rubber ring own material, it is additionally arranged after the mesh steel wire of individual layer 6, flexible joint can be effectively improved
Ring intensity.
The flexible steel bushing rubber ring of sealing, sets the mesh steel wire of individual layer 6, the structure increases rubber inside rubber ring
The bulk strength of ring, improves the stress performance of rubber ring when flexible steel bushing shield is received, improves its reusability.Rubber
Ring structure is as shown in Figure 1.
The mesh steel wire of individual layer 6 is laid in the flexible steel bushing rubber ring of one kind sealing, rubber.Shield ensures rubber when receiving
The intensity of ring, it is ensured that the integrity of rubber ring when shield is received.
The flexible steel bushing rubber ring intensity of increase, it is ensured that shield receives safety.
The present invention is simple in construction, protects steel bushing.
Brief description of the drawings
Fig. 1 is rubber ring section of structure.
Fig. 2 is the drawing in A portions.
In figure：1st, rubber ring, 2, the mesh steel wire of individual layer 6,3, bolt, 4, steel loop plate a, 5, steel loop plate b；
Embodiment
The rubber ring takes rubber ring when being received to shield to carry out force analysis, and the integrity to flexible steel bushing is controlled
System.The degree of safety that flexible steel bushing is received is not only increased, while extending the service life of rubber ring.
The mesh steel wire of individual layer 6 is set inside rubber ring, and by contrast, the invention can effectively increase the entirety of rubber ring
Intensity, improves the stress performance of rubber ring when flexible steel bushing shield is received, improves its reusability.Increase sealing is flexible
The intensity of rubber ring can ensure that the globality of flexible steel bushing in steel bushing, extend the service life of steel bushing, and more can guarantee that
Shield receives safety.
