Abstract
The utility model relates to a clamping device for detection of a football rebound rate of a football field. The clamping device mainly comprises a support frame and clamping release devices, wherein the support frame is mounted on a linear bearing of a movable rack of a detecting device and can be lifted to a regulated testing height with the movable rack; three clamping release mechanisms are uniformly distributed in a 120-degree angle manner and mounted on the support frame. According to the device, a football is supported to the regulated position by corresponding mechanisms, and falling of the football cannot be affected by clamping force; besides, the outage release mode is adopted, electromagnetic interference of an electromagnet cannot affect detection of the sensor; and the clamping device has the advantages of simple structure, convenience in operation and the like.
Description
Technical field
The utility model belongs to mounting technology field, is an assembly of pitch football bounce-back rate pick-up unit, is specifically related to a kind of pitch football bounce-back rate clamping device.
Background technology
Football bounce-back rate, be that football Vertical Free falls to the height rebounding behind surface, place and the number percent that starts height of drop, be to detect a whether qualified important indicator of pitch, National Standard of the People's Republic of China's " request for utilization of natural material sports field and method of inspection " (GB/T19995.1-2005) has made clear and definite regulation to the computing method of pitch football bounce-back rate.But up to now, the domestic measurement to pitch football bounce-back rate still adopts traditional manual type, to the research of pitch football bounce-back rate measurement mechanism seldom, have no corresponding detecting instrument and form product, put goods on the market.
The Chinese patent literature of Granted publication CN202710446U (application number 201220266974) discloses a kind of football clamping device of football bounce-back rate measurement mechanism, it mainly comprises: forward and backward web joint, left and right support optical axis, clamper front supporting plate, clamper rear carrier plate, left and right clamper optical axis, forward and backward clamper, forward and backward electromagnet, back-moving spring and balancing weight etc.
Except the patent of above-mentioned document, the clamping device of dependence test instrument all adopts hydraulic pressure or pneumatic pinch at present.
Summary of the invention
For current technical deficiency, the purpose of this utility model is to provide a kind of pitch football bounce-back rate clamping device, this device by corresponding mechanism by football holder at assigned position, can not affect because of the size of holding force the whereabouts of ball, the mode that adopts in addition power-off to discharge, the electromagnetic interference (EMI) of electromagnet can not affect the detection of sensor, and the advantage such as lamps structure is simple, easy to operate.
The technical solution adopted in the utility model is: a kind of pitch football bounce-back rate clamping device, comprising: bracing frame, be arranged on the linear bearing of pick-up unit movable stand, and can be thus lifted to regulation test height with movable stand; Clamp release mechanism, three covers, are 120 ° and are uniformly distributed, and are arranged on support frame as described above.
Further, support frame as described above comprises: annulus, and diameter is greater than football; Fixed adjustment arm, two, be connected on described annulus, described fixed adjustment arm is arranged on the linear bearing of movable stand, can carry out position adjustment according to the football status requirement that falls.
Further, described clamp release mechanism comprises: supporting seat, is arranged on support frame as described above annulus; Clamping limb, for clamping, release football; Fixed pin, for being arranged on described supporting base by described clamping limb; Electromagnet, is arranged on described supporting seat, just to said clamping limb; Retracing spring, one end is arranged on described supporting seat, and the other end is arranged on described clamping limb, during for electromagnet power-off, described clamping limb is retracted, and discharges football.
The utlity model has following advantage:
1. simple in structure, football is only had to anchorage force, can not affect because of the size of holding force the whereabouts of ball.
2. automatic centering, makes football freely fall completely when release.
3. power-off discharges football, avoids the impact of electromagnetic interference (EMI) on survey sensor.
4. cost is low.

Embodiment
Below by accompanying drawing and example, the utility model is described in further detail.
Embodiment 1: a kind of portable pitch football bounce-back rate pick-up unit, structure as Figure 1-3, comprising: bracing frame 1, be arranged on the linear bearing of pick-up unit movable stand, can be thus lifted to regulation test height with movable stand; Clamp release mechanism 2, three covers, are 120 ° and are uniformly distributed, and are arranged on support frame as described above 1.
Wherein, bracing frame 1 comprises: annulus 4, and diameter is greater than football; 3, two, fixed adjustment arm, is connected on described annulus 4, and described fixed adjustment arm is arranged on the linear bearing of movable stand, can carry out position adjustment according to the football status requirement that falls.
Wherein, clamp release mechanism 2 comprises: supporting seat 8, is arranged on support frame as described above annulus 4; Clamping limb 6, for clamping, release football; Fixed pin 5, for being arranged on described supporting seat 8 by described clamping limb 6; Electromagnet 7, is arranged on described supporting seat 8, just to said clamping limb 6; Retracing spring 9, one end is arranged on described supporting seat 8, and the other end is arranged on described clamping limb 6, during for electromagnet 7 power-off, described clamping limb 6 is retracted, and discharges football.
Operation steps of the present utility model is as follows:
1., before clamping device promotes, electromagnet 7 is switched on, and football is placed on clamping device.
2. clamping device arrives after specified altitude, gives electromagnet 7 power-off, and under the effect of retracing spring 9, three clamping limbs 6 open simultaneously, and football freely falls.
