The sensor base is fixed on the side of fragment-free track slab retrofilling layer template, the pressure head and the no tiny fragments of stone, coal, etc. rail
Guidance tape retrofilling layer contacts.
The present invention principle be：
After packing material irrigates, fragment-free track slab retrofilling layer intensity detecting device is arranged on by sensor base
Formwork sides, certain pressure is applied to packing material by pressue device, and measured by pressure sensor and displacement transducer
The compression strength of packing material under certain deformation condition, then result is calculated and be shown by tester main frame automatically, so as to
Accurately, fragment-free track slab retrofilling layer intensity is objectively reflected.Tester main frame can real-time display pressure and displacement change；Pass
Sensor base is used to fragment-free track slab retrofilling layer intensity detecting device being fixed on formwork sides.
The fragment-free track slab retrofilling layer intensity detecting device of the present invention, instrument is light and handy, easy to use, simple to operate, inspection
Degree of testing the speed is fast, the accurate objective, testing result of data can automatic printing and storage, improve fragment-free track slab retrofilling layer construction matter
Amount.
Its advantage can be summarized as two aspects：
1. fragment-free track slab retrofilling layer intensity detecting device, is existed using displacement transducer and pressure sensor automatic detection
The compression strength of packing material under certain deformation conditions, it accurately can objectively reflect fragment-free track slab retrofilling layer intensity.
2. being acquired, calculating to the output signal of pressure and displacement transducer by data acquisition device, data are detected
It is accurate objective；And testing result is shown automatically；The operating efficiency of detection work can be put forward, reduces the labor intensity of workmen.
Specific embodiment：
As shown in figure 1, after packing material irrigates, fragment-free track slab retrofilling layer intensity detecting device is passed through into sensor
Floor installation applies certain pressure in formwork sides, by pressue device to packing material, and passes through pressure sensor and displacement
Sensor measures the compression strength of the packing material under certain deformation condition, then is calculated and be shown automatically by tester main frame
As a result.
After detection terminates, tester main frame can be by the test data of storage, field print.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
