Detailed Description
The following examples are given for the detailed implementation and specific operation of the present invention, but the scope of the present invention is not limited to the following examples.
As shown in fig. 1-8, the noise reduction device for roads and bridges comprises a plurality of noise reduction assemblies 2 arranged at intervals left and right; noise in the road and bridge construction process is reduced through the noise reduction assembly 2.
Specifically speaking, every noise reduction assembly 2 all includes fixed plate body 21, the back lateral wall fixedly connected with a plurality of spring 23 of fixed plate body 21, a plurality of spring 23 is the rectangular array and distributes on fixed plate body 21. The noise reduction assembly 2 further comprises a noise reduction plate 22, and the noise reduction plate 22 is fixedly connected to the plurality of springs 23. Specifically, one end of the spring 23 is welded on the fixed plate 21; the other end of the spring 23 is welded to the noise reduction plate 22.
Each noise reduction plate 22 is fixedly connected with a plurality of damping corrugations 221 (the transverse cross sections of the damping corrugations 221 are triangular), and damping grooves are formed between the adjacent damping corrugations 221; the damping corrugations 221 are distributed in a left-right distribution on the noise reduction plate 22.
In the work progress, the noise meets damping flute 221 and damping groove, and the noise meets and refracts on damping flute 221 and the damping groove at the noise, and then the vibration can obtain effectual consumption.
In the use, a plurality of noise reduction assembly 2 cooperate the use, form one and can enclose fender that encloses fender post construction site, specifically speaking, for the convenience of angle regulation, it is articulated through the articulated elements between the above-mentioned noise reduction assembly 2.
The articulated elements include fixed connection and are located the middle part connecting rod 3 at fixed plate body 21 top (three fall make an uproar subassembly 2 and form one and can adjust in a flexible way enclose the fender, the fixed plate body 21 that is located the middle part hinges the fixed plate body 21 of both sides).
Meanwhile, the left end and the right end of the connecting rod 3 are rotatably connected with the adjacent parts through the fixed pin shafts 31, and the tops of the fixed plate bodies 21 are connected with each other.
In the same way, in the actual working process, the connecting rod 3 (the three noise reduction assemblies 2 form a fence which can be flexibly adjusted, and the fixing plate bodies 21 at the middle parts are hinged with the fixing plate bodies 21 at the two sides) at the bottom of the fixing plate body 21 is positioned at the middle part.
The top mode design realizes forming one and can enclose the fender with the construction site, and at enclosing the fender in-process, the noise consumes vibration energy according to above-mentioned mode.
Specifically, the connection structure between the noise reduction plate 22 and the spring 23 plays a role of reducing sound energy in addition to the vibration energy consumed by the damper corrugation 221 and the damper groove.
Specifically, when the noise reduction plate 22 and the springs 23 vibrate due to the sound of the noise reduction plate 22, the springs 23 not only can absorb the vibration energy, but also the noise reduction plate 22 can dissipate the vibration energy.
Meanwhile, in order to further reduce noise and consume noise energy, each noise reduction plate 22 is provided with a plurality of damping through cavities 222; the damping through cavity 222 is vertically arranged, and damping liquid or damping paste is filled in the damping through cavity 222.
During the vibration process, the damping fluid or the damping paste consumes the vibration energy.
In order to realize the convenience of replacing the damping fluid, the top of the damping through cavity 222 is in threaded connection with a sealing bolt 2221; specifically, the bottom of the damping through cavity 222 is open, and a sealing bolt 2221 is connected to the bottom of the damping through cavity 222 through a thread; seal bolt 2221 includes a screw portion and a screw head portion that are screwed onto damper through-chamber 222; an internal thread structure matched with the screw rod part is arranged on the cavity wall of the damping through cavity 222.
In order to effectively support the whole device, a plurality of support members 4 are fixedly connected to the front side wall of the fixing plate 21. Through the support component 4, the whole device is stably supported, and the specific structure is as follows:
the support members 4 each comprise a universal joint 431 hinged on the side wall of the fixed plate 21; the universal joint 431 is hinged with a support rod 43, and the bottom of the support rod 43 is connected with an embedded plate body 41; the bottom of the panel body 41 is fixedly connected with a plurality of conical nail rods 42.
The bottom of the supporting rod 43 is hinged with the top of the panel body 41 through a hinge structure; the hinge structure comprises a ball fixedly connected to the bottom of the support rod 43; the top of the embedded plate body 41 is provided with a limiting ball groove of a limiting ball; the limiting ball body is limited in the limiting ball body groove and can rotate relative to the limiting ball body groove.
The working process is as follows:
at first, arrange in proper order and open more than fixed plate body 21, because adopt articulated mode between the fixed plate body 21, consequently, angle regulation in a flexible way forms a circular shape and encloses the fender, encloses the fender isolation with the construction site.
After the enclosure, the conical nail rod 42 at the bottom of the embedded plate body 41 is driven into the ground, and at the moment, the whole device can be effectively supported on the ground.
Adopt above-mentioned device part design, not only can be effectively in road and bridge work progress, enclose the fender with the job site, and in the design of above-mentioned device part, because of adopting fixed plate body 21, fixed plate body 21's back lateral wall fixedly connected with a plurality of spring 23, fall the board 22 of making an uproar, damping flute 221, damping groove and realize in the work progress, can effectually reduce the noise.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
