Description
Technical field
The present invention relates to cushion technique field, particularly a kind of rubber shock-absorbing larynx for delivering concrete.
Background technology
Rubber shock-absorbing larynx is used for playing the hollow rubber product of immunity connection function between metallic conduit, is called rubber shock-absorbing again
Larynx, rubber shock absorber etc., is a kind of high resiliency, high-air-tightness, the pipe joint of resistance to medium and against weather.This product is abundant
Make use of rubber elasticity, high-air-tightness, media-resistant type, weatherability and radiation resistance the advantages of.It is divided into pine by connected mode
Set flange form, mounting flange formula and three kinds of screw-type, can be divided into single spheroid, double spheroid, reducing body, curved spheroid and blast by structure
Five kinds of coil pipe etc..General tubular rubber part is formed by rubber and wire loop, after high pressure, die material sulfidization molding again with metal
Flange or splice combinations form.This product can reduce vibration and noise, and can be to the benefit of having expanded with heat and contract with cold causing because of temperature change
Repay effect, be widely used in various pipe-line systems.
But the rubber shock-absorbing larynx that produces of current market be all after tubular rubber part sulfidization molding again with metal flange
Or splice combinations form, in the course of conveying of concrete, vibrations are very greatly it is easy to lead to rubber shock-absorbing larynx in combination even
Connect place's rupture, sealing is decreased obviously with damping effect, concrete also can be made to flow out, not only cause the loss of concrete, and
And it is easy to cause construction risk in building-site construction, personal injury is caused to site operation personnel.
Content of the invention
The invention aims to solving above-mentioned the deficiencies in the prior art, thus providing a kind of damping effect obvious, close
The reliable and stable rubber shock-absorbing larynx for delivering concrete of envelope property.
To achieve these goals, a kind of rubber shock-absorbing larynx for delivering concrete designed by the present invention, including circle
Circumferential body, described main body upper and lower ends are respectively equipped with main body coaxially with the O ring joint of internal diameter, on described joint uniformly
Some fixing holes are distributed with, described main body is respectively equipped with interior glue wearing layer, main body enhancement layer, middle glue casing play, master outward by interior

Joint protective layer is extended out and is integrally formed by interior glue wearing layer, and described joint protective layer is also coated on joint excircle.
Because joint protective layer is integrally formed with interior glue wearing layer, joint enhancement layer and main body enhancement layer, and joint protective layer is also right
Joint is cylindrical to be protected, rather than forms with metal flange or splice combinations after tubular rubber part sulfidization molding, significantly again
Improve the air-tightness of damping larynx, and the damping effect that ensure that damping larynx.
Further, the thickness at described middle glue casing play two ends is less than middle thickness, the thickness at described outer compound protective layer two ends
Degree is bigger than middle thickness, and this is provided with beneficial to the shaping between damping larynx main body and joint.
Preferably, it is evenly distributed with steel wire in described middle glue casing play, improve the damping effect of damping larynx.
Preferably, described enhancement layer is formed using nylon cord fabrics rubberizing.
Further, described main body enhancement layer has four layers, and is uniformly distributed in middle glue casing play both sides, so that described master
Body is respectively equipped with interior glue wearing layer, main body enhancement layer, main body enhancement layer, middle glue casing play, main body enhancement layer, main body outward by interior
Enhancement layer and outer compound protective layer, described joint have in be respectively equipped with outward steel disc layer, joint enhancement layer, steel disc layer, joint increase
Strong layer, steel disc layer, joint enhancement layer, steel disc layer, joint enhancement layer, steel disc layer and joint protective layer.Setting multilayer enhancement layer,
Be conducive to improving the resistance to stress ability of damping larynx, thus improving the damping effect of damping larynx.
The preparation method that this is used for the rubber shock-absorbing larynx of delivering concrete is: first by the interior glue wearing layer vulcanizating, master
Body enhancement layer, middle glue casing play, main body enhancement layer and outer compound protective layer are arranged outward by interior, will vulcanizate by glue in main body
Joint protective layer that wearing layer extends out, steel disc layer, the joint enhancement layer being extended out by main body enhancement layer, steel disc layer, by
Joint enhancement layer and the setting of steel disc layer ecto-entad that main body enhancement layer extends out, and the covering of joint protective layer is outside joint
On circumference, formed using the hot sticky compacting of adhesive one, the length of described interior glue wearing layer is longer than the length of main body enhancement layer, institute
The length stating main body enhancement layer is longer than the length of middle glue casing play and outer compound protective layer.By the hot sticky compacting of the method
Rubber shock-absorbing larynx does not have gap, long service life, reliable in quality.
When having concrete to pass through in damping larynx, due to many angular sandstone of the presence in concrete etc., can cut
Damping larynx, the service life of damping larynx substantially reduces, glue wearing layer in internal layer setting, can increase the use longevity of damping larynx
Life；It is provided with steel wire in middle glue casing play, steel wire has certain elasticity, the damping effect of damping larynx can be improved.
A kind of rubber shock-absorbing larynx for delivering concrete that the present invention obtains, it has the technical effect that this rubber shock-absorbing larynx,
