Beading backboard 1, aluminium alloy punching panel 6 are sandwiched in sound absorption cotton between the two, aluminum alloy frame 2, non-woven fabrics 4, press strip 7, single tube
Adhesive tape 9, rivet 10, load cell 11 between rubber strip 8, plate.Wherein:
Load cell 11 is arranged in 1 central area of aluminium alloy punching panel 6 and aluminium alloy beading backboard；Load cell
11 resistance-strain type of dynamometer sensor 11 high for response frequency are connect with panel and backboard using spot welding.
Aluminum alloy frame 2 includes girder 12, end socket 13, color zinc tapping screw 14, keel 15；Girder 12 is connected to aluminium conjunction
On the upside of golden punching panel 6 and beading backboard, downside；The end socket 13 is mounted on the left of aluminium alloy punching panel 6 and beading backboard,
Right side；Setting is I-shaped support keel 15 there are two interface between girder 12；Sound absorption cotton cuts corresponding size, along support dragon
15 slideway of bone is inserted between panel and backboard, the inside of aluminum alloy frame 2 and aluminium alloy beading backboard 1 and aluminum alloy frame 2
Between fill respectively be first sound absorption cotton 3 and second sound absorption cotton 5；Non-woven fabrics 4 is used to wrap up sound absorption cotton, rises waterproof and dampproof sun-proof
The effects of.
Rivet 10 is for being fixed, girder 12 and aluminium alloy punching panel 6, girder 12 and aluminium alloy beading backboard 1, envelope
Between first 13 and girder 12 and aluminium alloy punching panel 6, aluminium alloy beading backboard 1, between keel 15 and girder 12, between plate adhesive tape 9 with
Between girder 12, single tube rubber strip 8 and aluminium alloy punching panel 6 and aluminium alloy beading backboard 1, it is fixed to be all made of rivet 10.
Single tube rubber strip 8 is fixed on aluminium alloy punching panel 6,1 two sides of aluminium alloy beading backboard, and single tube rubber strip 8 is another
End is contacted with H profile steel column, is formed damping structure, is played the role of vibration damping, absorb the side of impulse load single tube rubber strip 8
It is provided with press strip 7.
Adhesive tape 9 is fixed on the outside of the lid of girder 12 between plate, ensures metal sound barrier flexible contact up and down, makes metal sound barrier
Fastening is more closely knit up and down, and acoustical absorptivity is stronger.
Resistance-strain type of dynamometer sensor 11 is arranged in aluminium alloy punching press panel and 1 inside middle portion of aluminium alloy beading backboard,
It is tightly attached to panel and back plate surface, and deformation changes with panel and backboard deformation, is based on strain effect principle, resistance value
Corresponding change occurs, multiple load cells 11 are adopted by connecting wire 16 by data by the electric signal generated after the effect of power
After collecting the acquisition of module 17, analysis, synthesis processing, the size and Orientation for acting on impulse load on metal sound barrier is restored.
The data that the utility model is acquired just for High Speed Railway Trains 250~350Km/h of speed per hour, data acquisition module 17
Computer can be further transmitted to be analyzed and processed, be compared with normal use load, when lower than the minimum of setting,
It alarms when occurring abnormal, realizes monitoring long-range, automation and intelligence.In addition, High Speed Railway Trains have deceleration to go
It sails or runs at a low speed, two sides intelligence sound barrier, which is not done, to react, i.e., only when train has 250Km/h and the above speed per hour, place
Reason device can just analyze the data of acquisition.
The metal sound barrier with monitoring function of the utility model has beneficial below compared with existing metal sound barrier
Effect:
(1) the metal sound barrier with monitoring function of the utility model can be used for railway, highway, urban track traffic neck
Domain, to impact load, the test and monitoring of additional load of temperature change generation etc..
(2) working principle of strain-type force sensor 11 is made based on strain effect, i.e. conductor or semiconductor material
When material generates mechanically deform under the action of external force, corresponding variation occurs for resistance value.Its monitoring principle are as follows: train passes through
When the impulsive load that generates act on acoustic barrier unit board, cell board generates vibration, and panel and its deflection of backboard are larger, with
Being continuously increased for impulsive load number, acoustic barrier unit board structure will appear loosening or cell board cracking etc. and destroy, loosen tight
Cell board part can fall off when weight, seriously affect train traffic safety.The key of the utility model is in aluminium alloy punching panel 6
Fixed resistance strains chip load cell 11 at medial center, and train acts on panel by the impulsive load generated, face
Plate generates deformation, and the strain chip load cell 11 for being then fixed on panel generates deformation together, and passes through data acquisition module
Block 17 is detected, and can solve the problems, such as the loosening that sound barrier can not be with the naked eye observed when train passes through；It is carried on the back in aluminium alloy beading
1 the same manner of plate is fixed to be solved backboard and is located on the outside of sound barrier with model sensor, daily to detect its loosening or damage
Problem.(3) data acquisition module 17 of the utility model, the data of acquisition are transmitted to after computer analysis is handled and normally make
It is compared with load, is alarmed when occurring abnormal, it can be achieved that monitoring long-range, automation, intelligence.(4) this is practical new
Type one data processor of every 100 meters of arrangements has velocity sensor at each data processor, for measuring train vehicle
Speed, 250Km/h is a valve point, if being lower than this speed, data processor is not handled to be sensed on diagnosis sound barrier panel and backboard
Data measured by device work normally if speed is more than or equal to this speed.
Specific case is applied in the utility model to be expounded the principles of the present invention and embodiment, it is above
The explanation of embodiment is merely used to help understand the method and its core concept of the utility model；Meanwhile for the one of this field
As technical staff, based on the idea of the present invention, there will be changes in the specific implementation manner and application range.To sum up
Described, the content of the present specification should not be construed as a limitation of the present invention.
