21 drive 22 compressed spring 26 of sliding axle to do exercises after the pressure by drawstring is transferred to microswitch 24, fine motion for pressure
Switch 24 is connected with control system, so that control system control suspention motor 1 reversion or prompting suspention motor 1 stop operating,
Sliding axle 22 resets under the elastic force effect of spring 26 after pressure disappearance.
When carrying out the pull force calculation of drawstring, apply pulling force of the wheels 9 by drawstring 12, will be drawn by lever shaft and mandril
Power reaches force snesor, and force snesor 11 is connected with control system, acts on and applies so that control system can obtain in real time drawstring
Pulling force on power wheel.
When specifically used, after drawstring on reel 3 changes direction by fixed pulley 6, by movable pulley 18, finally from applying
Power wheel 9 pulls out.In drawstring 12 by before fixed pulley 6, if 12 receiving/releasing of drawstring is to most weakness/most strong point, 12 meeting of drawstring
Pressure is reached microswitch 24 after runner stress by the runner for touching position-limit mechanism, and microswitch, which is closed, simultaneously reaches the information
Control system, so that control system control suspention motor 1 reversion or prompting suspention motor 1 stop operating, after pressure disappearance
Sliding axle 22 resets under the elastic force effect of spring 26 sends signal when receiving/prevent convenient for drawstring next time to extreme position；It is drawing
When rope 12 passes through movable pulley 18, movable pulley 18 is driven to move, in the movement of movable pulley 18 compressed spring 1 and spring two so as to
To buffer the pulling force of drawstring, anti-locking pulley 18 directly knocks fixed pulley fixed plate 7 under the action of the pulling force of drawstring, in pulling force
After disappearance, the elastic force of spring 1 and spring two discharges and restores to free state, so as to help movable pulley 18 to reset；?
For drawstring from when applying the pull-out of wheels 9, the pulling force effect of drawstring 12, can finally by mandril and force snesor to applying on wheels 9
To obtain the value of thrust from control system.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
