Abstract
The utility model provides a denoising device for a vehicle decelerator, comprising a brake track and a labyrinth-type restriction damping plate, wherein the labyrinth-type restriction damping plate is bonded with two waists and the bottom surface of the brake track by an adhesive; the labyrinth-type restriction damping plate consists of a high-damping polyurethane HDPU damping paint; and the adhesive is a B50 dynamic-load strong adhesive. The denoising device has the benefits that the labyrinth-type restriction damping plate is bonded with the brake track of the vehicle decelerator so as to absorb the vibration generated during the braking process of the decelerator, thus reducing the noise to a greater extent; and the denoising device has the advantages of simple structure, long service life, low machining cost, high production efficiency and the like.
Description
Technical field
The utility model relates to a kind of denoising device, especially relates to a kind of car retarder denoising device.
Background technology
The noise that railway classification yard retarder when work produces affects railroader and near resident's physical and mental health always.Along with the development of society, the enhancing day by day of people's environmental protection and occupational health idea is more and more paid attention to the noise that the work of railway classification yard retarder produces, and this just needs a kind of low noise of development, is fit to the braking rail that existing car retarder uses.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, car retarder denoising device that intensity is really up to the mark, safe and reliable.
The technical solution of the utility model is: a kind of car retarder denoising device, comprise braking rail and labyrinth type Constrained Plates, and described labyrinth type Constrained Plates is pasted on two waists and the bottom surface of described braking rail by adhesive agent.
Preferably, described labyrinth type Constrained Plates is made up of high-damping polyurethane HDPU damping paint.
Preferably, described adhesive agent is the tough assembly glue of B50 dynamic load.
Advantage and the good effect that the utlity model has are: bonding labyrinth type Constrained Plates on the car retarder braking rail, can absorb the vibration that the retarder glancing impact produces, and reduce noise largely; Have simple in structurely, the life-span is long, and tooling cost is low, the production efficiency advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the assembling scheme drawing of the utility model under retarder in closed state;
Fig. 3 is the assembling scheme drawing of the utility model under retarder released.
Among the figure:
1, braking rail 2, damping panel 3, stock rail
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises braking rail 1 and labyrinth type Constrained Plates 2, and described labyrinth type Constrained Plates 2 is pasted on two waists and the bottom surface of described braking rail 1 by adhesive agent.Described labyrinth type Constrained Plates 2 is made up of high-damping polyurethane HDPU damping paint, and temperature performance is stable, can adapt to various mal-conditions, antiageing, and damping ratio height.Described adhesive agent is the tough assembly glue of B50 dynamic load, all has excellent performance at aspects such as fatigue resistance, low-temperature adhesion performance, cold-and-heat resistent impact capacities.Two braking rail 1 that will have labyrinth type Constrained Plates 2 are assemblied in the both sides of stock rail 3, high frequency noise to the retarder glancing impact can reduce by 15～20 decibels, general noise reduces by 10～15 decibels, obviously improve the operating personnel's of marshaling yard working environment, and between used life need not to change all far above the life-span of braking clamping plate etc. the service life of the main material of labyrinth type Constrained Plates 2.
Above embodiment has been described in detail the utility model, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limit practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
Claims (3)
