The driving end of dynamic device 300 is parallel to the column 210, and does stretching motion immediately below the crossbeam 220；The hydraulic pressure is slow
It rushes device mounting structure 400 and is set to the working face 110, be used for 10 vertical 110 clamping of the working face of hydraulic bjuffer to be measured
It is fixed on the pedestal 100, and stretching motion is done under the telescopic action at the driving end of the retractable driving device 300；It is described
Column 210 is equipped with speed detection system, the speed detection system, the driving end for detecting the retractable driving device 300
Velocity magnitude when being hit every time with hydraulic bjuffer 10 to be measured.
The hydraulic bjuffer mounting structure 400 includes mounting seat 410 and block part 420；The mounting seat 410 is solid
Due to the working face 110, the cylinder body 11 for fixing hydraulic bjuffer 10 to be measured, the lid of block part 420, which closes, is fixed on institute
State the telescopic end 12 of hydraulic bjuffer；So that hydraulic bjuffer 10 to be measured is described flexible perpendicular to being set to for the working face 110
The underface at the driving end of driving device 300.The mounting seat 410 and the block part 420 are separated two parts, respectively
The cylinder body 11 of hydraulic bjuffer 10 to be measured and telescopic end 12 are fixed so that the simpler side of installation of hydraulic bjuffer 10 to be measured
Just.The telescopic end 12 and cylinder body 11 of hydraulic bjuffer to be measured 10 after being fixed still can be with relative motions, when described flexible
When the flexible shock block part 420 of the driving end of driving device 300, the block part 420 drives hydraulic bjuffer 10 to be measured
Telescopic end 12 together to cylinder body 11 move, realize the contraction of hydraulic bjuffer 10 to be measured；When the retractable driving device 300
Driving end when shrinking away from the block part 420, the telescopic end 12 of hydraulic bjuffer 10 to be measured in cylinder body 11 buffer solution and
It extends and restores under the action of elastic component, to drive the block part 420 to be moved to the position before being knocked, repeatedly, just
The process of the reciprocal telescopic work of hydraulic bjuffer 10 to be measured is simulated.
The block part 420 is cylindric, and end face is plane thereon, and lower face is equipped with and concaves towards in the block part 420
12 end of telescopic end of the vessel in portion, hydraulic bjuffer 10 to be measured is fastened in the vessel.Hydraulic bjuffer 10 to be measured
Telescopic end 12 fixed by the vessel, there are many fixed form, can be interference fit or using vessel side wall setting insert
The modes such as pin and screw so that the block part 420 becomes an entirety with hydraulic bjuffer 10 to be measured.So that described flexible
Driving end striking face with bigger when hitting hydraulic bjuffer 10 to be measured of driving device 300, hits when avoiding shock
Offset, while the block part 420 also acts as the telescopic end 12 of hydraulic bjuffer 10 to be measured the effect of protection, avoids prepare liquid

Cap 420 obtains side wall, and the lower surface at the edge is equipped with the reflective surface 521 of the reflector 520.The reflector 520 into one
Step increases the striking face of the block part 420, on the other hand cleverly utilizes the edge bottom surface of reflector 520 to be arranged described anti-
Smooth surface 521 so that the block part 420 becomes an entirety with the reflector 520, and structure is simpler, stablizes.
510 one end of the laser sensor is working end, and the other end is installation end, and the working end is filled equipped with Laser emission
It sets and receiving device, the installation end is fixed with the column 210, and can slide up and down adjusting along the column 210.Because
Under different use environments, when detecting the hydraulic bjuffer of different height, the difficulty for detecting stroke speed is different, it is necessary to
The laser sensor 510 is adjusted as the case may be at a distance from the working face 110, and the laser sensor 510 is slided
It is dynamic to be set on the column 210, with regard to solving the problems, such as this well, so that the practicability higher of the detector.
The detection device is additionally provided with information acquisition device, and the laser sensor 510 is electrically connected with described information collector；
Described information collector receives the number hit every time that the laser sensor 510 detects and corresponding speed values
Collection.The impact force inductor is a kind of common detector, can detect stroke speed when it is hit every time,
And the size for hitting number and each stroke speed is passed with numeric form.Described information collector collects these information
After store even analysis shows that, so that the test result of the detector more fast and accurately shows.
The technical principle of the present invention is described above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and it cannot be construed to limiting the scope of the invention in any way.Based on the explanation herein, the technology of this field
Personnel would not require any inventive effort the other specific implementation modes that can associate the present invention, these modes are fallen within
Within protection scope of the present invention.
