Description
Technical field
The present invention relates to a kind of height measuring device, particularly a kind of ball rebound height measurer is mainly used in the bounce-back ability index of measuring body sports floor to ball, also can be used for other.
Background technology
The bounce-back ability of the ball of physical culture timber floor is one of the major function of the physical culture timber floor of Germany's (DIN) industrial standard 18032 part iis regulation, be the indispensable part of physical culture timber floor standard detection item, intactly quoted the bounce-back rate function and the detection method of ball in the DIN standard among GB/T20239-2006 " physical culture wood floors " 6.2.5 of national inspection and quarantine general bureau in September, 2006 issue.Its detection method is described below:
1, detect principle: the standard basketball of utilization is measured the bounce-back height of basketball respectively on wood floors and firm ground, calculates the bounce-back rate of ball.
2, testing tool parameter: the height of band scale is the shelf of 2.2m.
A standard basketball.
3, detect step: a, basketball is manually lifted the basketball lower edge apart from ground floor 1.8m place.
B, basketball aeration quantity highly are that 1.3m ± 25mm is as the criterion with the bounce-back on solid mattess.
C, respectively on solid mattess and detection faces, measure the bounce-back height of ball, both the basketball upper limb was accurate to 5mm apart from the distance of ground floor.
D, each check point carry out 5 times to be measured, and also can increase the detection number of times as required.
General direct optics or the acoustics acquisition scheme of adopting of the data acquisition approach of ball bounce-back in the testing process.
4, detected value calculates: the bounce-back rate B of ball
rCalculate by formula, represent, be accurate to 1% with number percent
B
r=h/h
1In * 100% formula:
B
rThe bounce-back rate of-ball, %;
h
1-ball is at the bounce-back height of firm ground, and unit is a millimeter (mm);
The bounce-back height of h-ball on detection faces, unit is a millimeter (mm).
The test result of each test point is the arithmetic mean of 5 test results, is accurate to 1%.
The testing agency of german standard din approval does not make detail requirement to the support of measuring the ball height of drop in the spheroid rebound function.
Defective on the present detection method:
1, needs artificial basketball is promoted to require height in the testing process, and need manpower control basketball, can not eliminate artificial factor.
2, the direct optically detecting scheme of the general employing of data acquisition approach in the testing process can not be eliminated the deviation of bringing in the naked eyes identification.
3, spheroid fall to adopt the manual mode of operation, can not avoid in the dispose procedure palm to the friction force of basketball.
4, the height of basketball releasing means is that fix, nonadjustable, can not guarantee the stability of installing in use for some time like this, altitude datum that promptly can not assurance device.
Summary of the invention
The purpose of this invention is to provide the ball rebound height measurer that does not have other external force influence when nobody is for factor, spheroid free-falling in a kind of test process, can arbitrarily adjust the spheroid height of drop, overcome the deficiencies in the prior art.
Ball rebound height measurer of the present invention comprises the slideway 6 of vertical setting, and slideway 6 bottoms are connected to bearing, is furnished with slide block 7 mutually with slideway 6, slide block 7 joins with suction cup carrier 11, and described slide block 7 also is connected to screw mandrel, screw jacking gear, is provided with the sucker that joins with vacuum plant on suction cup carrier 11.
Ball rebound height measurer of the present invention, wherein said bearing is formed by the base plate 1 that is positioned at the bottom with the support plate 2 of base plate 1 perpendicular setting, be connected to web joint 3,4 on the support plate 2, web joint 3,4 and slideway 6 join, in the bottom of slideway 6 slideway lower end 13 is arranged, slideway lower end 13 is fixedlyed connected with base plate 1.
Be provided with the lifting support 8 that parallels setting with slideway 6 between the ball rebound height measurer of the present invention, wherein said slide block 7 and suction cup carrier 11.
Ball rebound height measurer of the present invention, wherein said screw mandrel, screw lifting device structure are: the section of slideway 6 is flute profile, screw is positioned at the groove of slideway 6, and join by notch place and slide block 7, the screw mandrel that matches with screw places in the groove of slideway 6, the bottom head and the slideway lower end 13 of screw mandrel are rotationally connected, the upper end of slideway 6 is connected to slideway upper end 12, the top of screw mandrel and slideway upper end 12 are rotationally connected, and the termination is stretched out with handwheel 10 and is joined, slideway upper end 12 connects chute 9, and chute 9 matches with described lifting support 8.
Ball rebound height measurer of the present invention, because vertically the bottom of the slideway 6 that is provided with is connected to bearing, is furnished with slide block 7 mutually with slideway 6, slide block 7 joins with suction cup carrier 11, described slide block 7 also is connected to screw mandrel, the screw jacking gear, on suction cup carrier 11, be provided with the sucker that joins with vacuum plant, before test, can pass through screw mandrel, screw drives slide block 7 and moves up and down along slideway 6, thereby the sucker that drives on suction cup carrier 11 and the suction cup carrier moves up and down, and determines the height of test request, and spheroid is inhaled on sucker through vacuum plant, discharge spheroid by vacuum plant then and make its free-falling, but in this process, do not appoint human factor, do not have other external force influence during the spheroid free-falling, guaranteed the accuracy of test, the data precision height of gathering, error is little; This device cooperates with the pressure transducer that rest on the ground or tested floor is located, pressure transducer and treatment circuit join, the priority of landing for the second time after spheroid lands for the first time and rebounds measures signal by sensor and sends into treatment circuit and demonstration, need not range estimation, overcome the inaccurate defective of range estimation in the prior art; This device can arbitrarily be adjusted and determine the spheroid height of drop, and is convenient, flexible, simple in structure.
