The true elastic state for testing out steel wire rope 8, moreover, the setting of two feeler levers 601 and two force cells 604, greatly
Improve the security of travelling winch, even if one of break down, the dual released rope detecting device 6 can with normal work,
It is the very effective device for preventing the slack rope of steel wire rope 8 from causing equipment loss and security incident.
Preferably, arrangement of clutch 204, force-measuring sensing device 205 and thin oil lubricant mechanism are additionally provided with described reduction box 2
206, arrangement of clutch 204 is arranged between stand-by motor input shaft 203 and the final-stage gear 207 for being transferred to the axle, and structure is end
Level gear 207 has the small external toothing of section as half-clutch device 208 by bearing and axis connection on gear, it is another for internal tooth half
Clutch is mounted on an axle by spline, and the half-clutch device can be axially moveable on axle, by shifting fork device can stir its with
The engagement of half-clutch device or separation on gear, when 4 normal work of main motor, arrangement of clutch 204 separates, the not work of stand-by motor 5
Make, when main motor 4 breaks down, arrangement of clutch 204 is engaged, and stand-by motor 5 is started working, and continues to run with travelling winch.
Force-measuring sensing device 205 is arranged on the bearing outer ring of the intergrade gear shaft of reduction box 2, and stress annulus can be selected, can be according to should
The deformation measurement of power annulus fixing point goes out the power of Axial and radial, so as to accurately measure the pulling force of steel wire rope 8 indirectly.Thin oil moistens
The high temperature lubricating thin oil of the speed end of reduction box 2 is drawn out that (speed end has oil-feed respectively by sliding mechanism 206 from speed end oil-out
Mouth and oil-out), after bearing pedestal cooling device, thin oil temperature reduction is again passed through lubrication thin oil by greasing cycle pipeline
Oil inlet sends the speed end of reduction box 2 back to, so as to protect bearing.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
