Description
Technical Field
The utility model relates to the technical field of noise reduction carriage plates, in particular to a carriage plate structure with two-stage noise reduction.
Background
At present, most of carriage plate structures used by special operation vehicles on the market adopt sandwich composite plates formed by one-time composite, and the carriage plate has almost no noise reduction function, so that noise reduction effect is optimized, and the noise reduction plates are independently arranged on the outer sides of the carriage plate in a common way. However, the improved car plate structure can only realize one-time noise reduction, and still cannot meet the requirements in the environment with higher noise reduction requirements. Therefore, a car plate structure with a two-stage noise reduction function has been developed.
Disclosure of Invention
The utility model mainly aims to provide a carriage plate structure with two-stage noise reduction, which is used for solving the problems that the noise reduction effect is poor and only one-time noise reduction can be realized in the prior art.
In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:
a two-stage noise reduction carriage plate structure comprises a carriage plate framework. A layer of high-strength plate is pressed on the left side of the carriage plate framework, and the carriage plate outer skin is pressed on the left side of the high-strength plate; the right side of the high-strength plate is filled with a noise reduction plate, the right side of the noise reduction plate is fixed with a detachable inner skin of the carriage plate, and the inner skin of the carriage plate is flatly attached to the noise reduction plate; the right side of railway carriage or compartment board skeleton is provided with the second grade and falls the skeleton of making an uproar, and the inside packing of second grade falls the skeleton and has the board of making an uproar of second grade, and the right side of board of making an uproar falls the board of making an uproar of second grade is fixed with detachable second grade and falls the covering of making an uproar.
Further, the high-strength plate and the noise reduction plate are bonded together through an adhesive. The high-strength plate and the noise-reduction plate can be well combined by using the adhesive, the high-strength plate also has a certain flattening effect on the noise-reduction plate, and the situation that the flatness of the carriage plate structure is reduced and even bulges after the carriage plate structure is used for a long time is avoided. More importantly, the high-strength plate improves the overall strength of the carriage plate structure, so that the application range of the carriage plate structure is further widened.
Further, the adhesive is glue. The glue is economical and practical and has good bonding effect, and is commonly used for bonding various plates.
Further, the noise reduction plate and the secondary noise reduction plate are both made of noise reduction cotton. In the practical application process, noise reduction cotton with different thickness and density can be selected according to specific scenes, so that the noise reduction requirement of the specific scenes is met.
Further, the skin in the carriage plate is fixed on the carriage plate framework through rivets, and the secondary noise reduction skin is fixed on the secondary noise reduction framework through rivets. The rivet fixing mode is adopted, and the skin in the compartment plate is not directly pressed on the skin framework, so that the later maintenance is considered. By adopting the detachable structure, the carriage plate structure is convenient to maintain in the later period. The manner in which the secondary noise reduction skin is secured is also considered the same and will not be described in detail herein.
Further, the carriage plate framework, the high-strength plate, the noise reduction plate, the secondary noise reduction framework and the secondary noise reduction plate are arranged in parallel.
The utility model also includes other components that enable normal use of the two-stage noise reduction deck structure, all using techniques conventional in the art. In addition, the devices and components not limited in the utility model all adopt conventional technical means in the field, such as glue, noise reduction cotton and the like. In the implementation process, a proper equipment or component model can be selected according to a specific working scene.
The working principle of the utility model is as follows: firstly, the outer skin of the carriage plate is bonded with the carriage plate framework and the high-strength plate by glue, and then the carriage plate and the carriage plate framework are compounded together by a press machine. The high-strength plate improves the overall strength of the carriage plate structure, has a certain flattening effect on the noise-reducing plate filled at the left side of the high-strength plate, further ensures the flatness of the appearance of the carriage plate structure, and the filled noise-reducing plate has a good noise-reducing effect. The two-stage noise reduction plate can realize two-stage noise reduction, and greatly enhance the noise reduction effect of the utility model. In addition, the detachable rivet structure is adopted to fix the inner skin of the carriage plate and the secondary noise reduction skin, and the direct pressure is not compounded, so that the later maintenance is facilitated.
Compared with the prior art, the utility model has the following beneficial effects: 1. the noise reduction effect is good: the carriage plate structure is filled with the noise reduction plate and the secondary noise reduction plate, so that the secondary noise reduction is realized, and the noise reduction effect is good; 2. the later maintenance is convenient: two assembly modes of pressure compounding and rivet are adopted, so that later maintenance is facilitated, and flatness of the carriage plate structure is guaranteed. 3. Carriage plate structure intensity is high, and application range is extensive: high-strength plates are pressed in the carriage plate structure, so that the overall strength of the carriage plate structure is improved.
