Embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe.
Like Fig. 1, Fig. 2, shown in Figure 3, the utility model sports ground multifunctional digital code tester comprises standoff foot rest 3 is installed that foot rest 3 has three, and foot rest 3 outsides are equipped with regulates supporting leg 15.In the support upper end spiral positioning suspension rod 7 is installed, suspension rod 7 lower ends are connected with releasing means 9, in releasing means 9, are lifted with the device that drops hammer, and positive middle part is provided with pick-up unit below support; Support includes the column 1 of both sides and the frame plate 16 on top; Spiral positioning suspension rod 7 tops are provided with handwheel 8, and these suspension rod 7 outsides are screw thread, pass also rack-mount frame plate 16 middle parts; Drop hammer device middle part is hammer body 2, and the center, top of hammer body 2 is provided with connecting link 10, and center, hammer body 2 bottoms is provided with impact head 4, and hammer body 2 outsides are provided with sleeve pipe 11, and sleeve pipe is on described column 1; Drop hammer device middle part is hammer body 2, and the center, top of hammer body 2 is provided with suspension hook 10, and center, hammer body 2 bottoms is provided with impact head 4, and hammer body 2 outsides are provided with pilot hole 2a, are sleeved on the column 1 through its inner linear bearing 21 in the pilot hole 2a; Hammer body 2 tops are connected with counterweight 2b, and are set with cover.Pick-up unit is the digital detector of belt sensor, comprises sleeve 17 and the spring 5 that is installed in the sleeve 17, sensor installation 6 in sleeve 17 lower ends 13, and sensor 6 is laser displacement sensor or ultrasonic displacement sensor.Lower end 13 bottoms at sleeve are connected with domain 14, are provided with the platen 12 with this spring coupling on the top of spring 5; Be provided with three guiding supporting seats 22 outside the described pick-up unit sleeve 17, each guiding supporting seat 22 inboard is provided with two bearings 23 and contacts with described sleeve 17 outer walls.The tester of the utility model can cross serial ports with the computer expert or USB is connected, and instrument to collect speed is greater than 1000 times/second, and then complete machine is light and handy if adopt portable notebook, and is easy to carry; If adopt desktop computer, then can in testing laboratory, use.
When carrying out the absorption of vibrations measurement:
Measurement mechanism is vertically placed.The device height control arrives (55 ± 0.25) mm dropping hammer.After the preliminary examination that does not once keep a record, carry out three times at every and measure, average.Each time interval of measuring is about 1min, also can the height that the device that drop hammer is adjusted to (22 ± 0.25) mm and (88 ± 0.25) mm be measured.
When carrying out the vertical deformation measurement:
Impulsive force vertically acts on the floor covering.The device that drops hammer highly drops on the pressing plate on spring top from 30mm at least.When the floor is tested, should device be suspended on the tripod, the strong point of this tripod is put 1.5m at least apart from load test.Need to install firmly to be fixed on the tripod, thereby in measuring process, guarantee load is vertically affacted on the tested floor covering.The displacement transducer of Displacement Measurement is fixed on the tripod equally.The device that drops hammer will be adjusted to and just touch on the spring that does not have load.For the adjustment device height that drops hammer, upwards push away with the handgrip piston, high placing in the cover of about 30mm with parallel plane gauge block; And piston placed on the cover, decontrol to drop hammer then and indicate the pressure condition of device on spring of dropping hammer, and remove gauge block once more when tested floor covering is out of shape up to pressure gauge; Under the vertical checkout condition; The contact of the displacement transducer of both sides touches on the horizontal contact plate that establish relatively both sides on the base, presses releasing means, and the device that drops hammer promptly is released.The device that drops hammer lands on the spring and rebound once more, so repeats repeatedly, and height of drop is more and more littler, is parked on the spring at last.When the device that drops hammer was released, the measuring-signal pen recorder was started working, and this measurement repeats repeatedly at each measurement point.
When carrying out the measurement of vertical deformation rate:
Measure said the operation according to vertical deformation, need on floor covering, replenish a displacement transducer is installed.This sensor passes is from the distance of proving installation axis xmm to 500mm, and the depression on the device axis that so just can record and drop hammer is worth the depression value at corresponding test point place.
Vertical deformation rate WX or W500 are its implications of secondary indication, promptly be worth and represent with the drop hammer depression of device axis xmm to 500mm place point of distance, and calculate according to this its with the device axis that drops hammer on the number percent of maximum depression value.
The utility model can be tested parameters such as athletic ground surface vibration absorption, vertical deformation and vertical deformation rate; Adopt laser triangulation sensor; Full accuracy can reach 1um, and analog quantity and switching value output can independently be provided with detection window, thereby satisfy the detection needs of national standard better.
