Formula makes 7 coiling of striking line on remote control idler wheel, is rotated by distant control idler wheel to transfer striking line 7.It is rolled using remote control
Wheel can make the winding of striking line 7 more convenient, also more smoothly in decentralization process, it is not easy to clamping stagnation occur.It is of course also possible to
Transferring slowly for striking line 7, such as the suitable friction of setting at the line outlet of remote control wire dispenser 5 are realized using other modes
Part, so that by suitable resistance when striking line 7 is transferred under the gravity of counterweight 8, to reach the effect transferred slowly
Fruit.
According to actual needs, the set-up mode for being remotely controlled idler wheel can be divided into two kinds.Since striking line 7 is using circuit fusing
When line, it will fuse, can not reuse after phase fault test.It is therefore contemplated that striking line 7 is disposable
, it is corresponding in remote control operation, it is only necessary to realize the decentralization to striking line 7, can not realize packing up to striking line 7.

The output end of remote-control motor is connect with the shaft of spiral idler wheel, by distant control motor, drives the rotation of spiral idler wheel, from
And realize the decentralization of striking line 7.Also, the controllability of remote-control motor is very strong, can not also be turned with forward and reverse, from
And it can transfer, stop decentralization or up withdraw striking line 7 at any time according to actual needs.
And in order to save cost, it can not also realize packing up to striking line 7, remote control idler wheel is arranged to remote-controlled lock and volume
The combination of line idler wheel.In the test preparation stage, lock-bit limitation is carried out to spiral idler wheel by remote-controlled lock, prevents its rotation, and
After testing crew is withdrawn, when can start test, is locked and unlocked by distant control, make striking line 7 in the gravity of counterweight 8
Effect is lower to be pulled, and the rotation of spiral idler wheel realizes that counterweight 8 falls slowly.
It should be understood that it can be made to have suitable resistance through reasonable settings at the shaft of spiral idler wheel, from
And the falling speed of counterweight 8 can be regulated and controled；It is of course also possible to be realized by adjusting the weight of counterweight 8, can also pass through
The cooperation of counterweight 8 and shaft rotary resistance is realized, is not specifically limited herein.

Matched card slot is locked in control, and remote-controlled lock can be set in the position with pocket matches.For example card slot can be set on the inside of shaft,
Remote-controlled lock also can be set inside shaft, and in lock state, the bolt of remote-controlled lock can be caught in the card slot of shaft, to limit
The rotation of shaft processed；The outer rim in spiral idler wheel also can be set in card slot, correspondingly, remote-controlled lock also can be set at outer rim,
Bolt can be caught in the card slot of outer rim when locking, can equally limit the rotation of spiral idler wheel.
The rotation of spiral idler wheel can make counterweight 8 fall, but in practical operation, and striking line 7 and counterweight 8 are by existing
The influence of field wind-force effect, it is vertical that the fall trajectory of counterweight 8 is not necessarily.For such situation, can install in advance
Nearby release plumb line confirms the setting position of discharge component 6 to point.Confirm after reasonably position is set, can pass through
The stroke of the strip connecting rod of the first fixed frame 3 or the second fixed frame 4 is adjusted, so as to adjust remote control wire dispenser 5 or discharge part
The setting position of part 6 is located at discharge component 6 on the default fall trajectory of counterweight 8, it is ensured that the smooth realization of phase fault.
In order to mitigate the damage that experimental rig is received in short trouble as far as possible, discharge component 6 is specifically as follows electric discharge and dissipates
Hot plate.Electric discharge heat sink can disperse the heat generated when short circuit faster, and the fireball generated when to dispersing air breakdown is right
