Abstract
The utility model discloses an engineering machine tool driver's cabin of making an uproar falls, including driver's cabin roof, driver's cabin right side plate, driver's cabin rear side plate, door and interior trim, all be provided with the material layer of making an uproar falls between the inboard of interior trim and driver's cabin roof, between the inboard of interior trim and driver's cabin right side plate, be provided with the heat insulating material layer of making an uproar falls between the inboard of interior trim and driver's cabin rear side plate. The engineering machinery cab can absorb and weaken noise entering the cab by arranging the noise reduction material layer, so that the noise reduction effect in the cab is effectively improved. In addition, because the engine compartment of the engineering machinery is positioned behind the cab, the noise reduction and heat insulation material layer is arranged on the rear side plate of the cab, so that the noise can be absorbed, and the heat insulation effect can be achieved.
Description
Technical Field
The utility model relates to an engineering machine tool driver's cabin technical field, concretely relates to engineering machine tool driver's cabin of making an uproar falls.
Background
With the continuous development of engineering construction industry, the field of engineering machinery manufacturing is also continuously strong, but the engineering machinery usually generates great noise in the use process, particularly high-power engineering machinery, the external radiation noise is more obvious, the excessive noise can influence the physical and mental health of people, and the driver of the engineering machinery takes the lead.
The cab of the engineering machinery is generally formed by welding steel plates, and can meet the rigidity and structural requirements required by the cab, but has the problems of insufficient sound absorption and noise insulation performance and the like. At present, generally lay a layer of rubber pad in the driver's cabin and play the effect of making an uproar, the drawback that this kind of mode exists is: the rubber pad need only match the gap that just can avoid producing the hourglass noise with the driver's cabin completely, and this results in tailorring of rubber pad complicated relatively, moreover, utilizes the rubber pad to fall makes an uproar, and the effect is relatively poor.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at providing an engineering machine tool driver's cabin of making an uproar falls in order to improve the noise reduction effect of driver's cabin.
The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides an engineering machine tool driver's cabin of making an uproar falls, includes driver's cabin roof, driver's cabin right side plate, driver's cabin rear side plate, door and interior trim, all be provided with the material layer of making an uproar falls between the inboard of interior trim and driver's cabin roof, between the inboard of interior trim and driver's cabin right side plate, be provided with the heat insulating material layer of making an uproar falls between the inboard of interior trim and driver's cabin rear side plate.
Further, the inboard of driver's cabin rear side plate is provided with hollow stand, the bottom of hollow stand is provided with the shrouding.
Further, the cab roof, the cab right side plate and the cab rear side plate are welded together.
Furthermore, the interior trim is fixedly connected with the cab top plate, the cab right side plate and the cab rear side plate through screws.
Further, one side of the noise reduction material layer, which is far away from the interior trim, is provided with a protrusion.
The utility model has the advantages that:
the utility model discloses an engineering machine tool driver's cabin of making an uproar falls, including driver's cabin roof, driver's cabin right side plate, driver's cabin rear side plate, door and interior trim, all be provided with the material layer of making an uproar falls between the inboard of interior trim and driver's cabin roof, between the inboard of interior trim and driver's cabin right side plate, be provided with between the inboard of interior trim and driver's cabin rear side plate and fall the thermal insulation material layer of making an uproar. The engineering machinery cab can absorb and weaken noise entering the cab by arranging the noise reduction material layer, so that the noise reduction effect in the cab is effectively improved. In addition, because the engine compartment of the engineering machinery is positioned behind the cab, the noise reduction and heat insulation material layer is arranged on the rear side plate of the cab, so that the noise can be absorbed, and the heat insulation effect can be achieved.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 to 4, the noise reduction engineering machinery cab of the embodiment includes a cab roof 3, a cab right side plate 7, a cab rear side plate 5, a vehicle door 8 and an interior 1, the cab roof 3, the cab right side plate 7 and the cab rear side plate 5 are welded together, and the interior 1 is fixedly connected with the cab roof 3, the cab right side plate 7 and the cab rear side plate 5 through screws; noise reduction material layers 2 are arranged between the inner side of the cab roof plate 3 and the inner side of the cab right side plate 7 and between the inner side of the cab right side plate 7 and the inner side of the cab rear side plate 5 and the inner side of the trim 1, and noise reduction and heat insulation material layers 6 are arranged between the inner side of the cab rear side plate 5 and the inner side of the trim 1.
The engineering machinery cab of the embodiment can absorb and weaken noise entering the cab by arranging the noise reduction material layer 2, so that the noise reduction effect in the cab is effectively improved. In addition, since the engine compartment of the construction machine is located behind the cab, the noise reduction and heat insulation material layer 6 is arranged on the rear side plate of the cab, so that the noise can be absorbed, and the heat insulation effect can be achieved.
As a further improvement to the above technical solution, a hollow upright post 4 is arranged on the inner side of the cab rear side plate 5, and a sealing plate 9 is arranged at the bottom of the hollow upright post 4. The hollow upright post 4 plays a role in supporting and insulating heat; the bottom of the hollow upright post 4 is blocked by adopting the closing plate 9, so that the noise can be reduced and the noise can enter the cab from the bottom.
As a further improvement to the above solution, as shown in fig. 5, the side of the noise reduction material layer 2 facing away from the interior trim 1 is provided with a protrusion 10. Through setting up the arch, can make noise multiple reflection, absorption, be favorable to improving noise reduction effect.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
