Abstract
The utility model relates to a box-type noise-preventing device of a hydraulic breaker. The box-type noise-preventing device of the hydraulic breaker comprises a breaker main shell and a noise-preventing shell, wherein the noise-preventing shell is mounted outside the breaker main shell in a sleeving way; the box-type noise-preventing device of the hydraulic breaker is characterized in that a vibration-absorbing plate is arranged between the noise-preventing shell and the breaker main shell; the vibration-absorbing plate comprises steel vibration-absorbing plate bodies; a polyurethane rubber plate is arranged on at least one pair of the steel vibration-absorbing plate bodies. The box-type noise-preventing device of the hydraulic breaker has the advantage of capability of effectively preventing noises generated between the main shell and the vibration-absorbing plate.
Description
Technical field
The utility model relates to hydraulic burster technical field, relates in particular to a kind of box noise preventing device of hydraulic burster.
Background technology
During hydraulic burster work, there is inevitable high-decibel noise, in order to be applicable to some, noise is limited to large occasion use, as constructed in residential block, existing hydraulic burster has adopted mute type Anti-noise shell, has used steel vibration damper plate between hydraulic burster host shell and Anti-noise shell.Due to the Incoercibility of steel, its fit clearance requires can not be too little, otherwise assembling difficulty can occur.For guaranteeing that hydraulic burster host shell can be assembled in Anti-noise shell smoothly, generally by the clearance control between Anti-noise shell and host shell in 2mm left and right, this just causes host shell in Anti-noise shell, to have larger scope of activities, cause due to high-frequency vibration, between host shell and vibration damper plate, can there is frequent impact phenomenon, and then produce extra noise, affected the muting function of this Anti-noise shell.
Utility model content
The utility model is for above-mentioned the deficiencies in the prior art, and a kind of box noise preventing device that can effectively prevent from producing between host shell and vibration damper plate the hydraulic burster of noise is provided.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of box noise preventing device of hydraulic burster, comprise breaker host housing and Anti-noise shell, described Anti-noise shell is sleeved on the outside of described breaker host housing, it is characterized in that, between described Anti-noise shell and described breaker host housing, be provided with vibration damper plate, described vibration damper plate comprises steel vibration damper plate body, and described at least one pair of, steel vibration damper plate body is provided with polyurethane rubber plate.
The beneficial effects of the utility model are: due to polyurethane rubber plate being set on described vibration damper plate, not affecting under the prerequisite of the smooth assembling of breaker host housing, reduced the gap between Anti-noise shell and host shell.Due to the elastic effect of polyurethane rubber plate, avoided the collision noise between Anti-noise shell and host shell.
On the basis of technique scheme, the utility model can also be done following improvement.
Further, the front portion of described steel vibration damper plate body is ramped shaped.
Adopt the beneficial effect of above-mentioned further scheme to be, slope is convenient to when assembling, main body be entered in the space being limited by vibration damper plate smoothly.
Further, be also provided with adjustment block described at least one on vibration damper plate body, described adjustment block is arranged on described Anti-noise shell, and is connected with described polyurethane rubber plate.
Adopt the beneficial effect of above-mentioned further scheme to be, adopt regulating block can regulate easily the gap between polyurethane rubber plate and breaker host housing.
Further, described polyurethane rubber plate is embedded on described steel vibration damper plate body.
Adopt the beneficial effect of above-mentioned further scheme to be, this mounting structure is convenient to be installed, and is convenient to change at any time after the wearing and tearing of polyurethane rubber plate.
