Abstract
The utility model provides a low-noise environment-friendly energy-saving cab for construction machinery, which belongs to the field of structure of construction machine bodies, such as excavating machine body, loading machine body and the like. The cab comprises an upright column, an inner cavity arranged inside the upright column and a polyurethane foam filler packed inside the inner cavity. The utility model has the benefits as follows: the noise in the position of the driver inside the cab is effectively reduced to below 80 dB (A), as compared to the noise level ranging from 88 dB (A) to 92 dB (A) in the prior art.
Description
Technical field
The utility model relates to all kinds of Mechanical Engineering Bodies, as the structure field of excavating machine vehicle body, loader vehicle body etc.
Background technology
Show that according to the present test data statistics of construction machinery product person between 88～92dB (A) is in the majority for domestic construction machinery product operator's compartment driver position noise, only have few products to reach to be lower than 88dB (A) and near the level of 85dB (A).The operator's compartment noise not only chaufeur is felt and working ability produces passive influence, and can cause healthy serious imbalance, tired, become deaf in early days, hypertension, sacred disease etc.Crossing strong noise mainly causes damage to people's auditory system.The environmental protection of construction machinery product, energy-conservation, noise reduction become the most important condition that the user selects gradually.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of low noise environment-friendly and energy-efficient engineering machinery driving cabin that can significantly reduce driver's position noise to be provided.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of low noise environment-friendly and energy-efficient engineering machinery driving cabin, comprise column, and in the described column cavity is set, the isocyanurate foam extending agent is set in the cavity.
The beneficial effects of the utility model are: effectively with operator's compartment driver position noise,, be reduced to below the 80dB (A) between 88～92dB (A) from the conventional products sound level.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1,, comprise column 1, cavity 2 is set in the column 1, isocyanurate foam extending agent 3 is set in the cavity 2 for a kind of low noise environment-friendly and energy-efficient engineering machinery driving cabin.
Claims (1)
1. a low noise environment-friendly and energy-efficient engineering machinery driving cabin comprises column, it is characterized in that: in the described column cavity is set, the isocyanurate foam extending agent is set in the cavity.
