Electric device life test method in the known technology is primarily aimed at many revolution electric devices, for part turn round electric device particularly the stand alone type part turn round electric device and still do not have comparatively ideal life test apparatus.Part turning valve electric device output shaft when work is done the part revolution, and general output shaft is done 90 ° of rotations, and existing part turning valve electric device test mechanism generally has two classes, and a kind of is combined type, and a kind of is stand alone type.It is to be combined by many turning valves of one-level electric device and reducing gear that combined type partly turns round the electric device test mechanism, and many swingings electric device for valve test mechanism has comprised the durability test of this form; Stand alone type part turning valve electric device test mechanism is that whole reducing gears are included in the main box, so that product reaches the output speed scope of 0.5-2.0r/min, comes electric device for valve partly turned round and tests.Above-mentioned two class part turning valve electric device test mechanism complex structures, installing/dismounting inconvenience, and only be suitable for the durability test of the electric device for valve of larger caliber.
Summary of the invention
The utility model for solve the technical matters that exists in the known technology provide a kind of simple in structure, volume is little, be fit to the free-standing part turning valve electric device durability test mechanism of more small-bore part turning valve electric device.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of free-standing part turning valve electric device durability test mechanism, comprise test-bed, the input shaft of on the test-bed crossbeam, installing, it is characterized in that: also comprise the arm of force, piston rod and the hydraulic jack that is connected with piston rod, described input shaft connects the arm of force by alignment pin, input shaft is provided with breach near arm of force place, arm of force bearing pin is installed in breach, arm of force bearing pin is installed on the arm of force, the arm of force connects piston rod, and the both sides test-bed of the arm of force is provided with and closes the valve positive stop and open the valve positive stop.
The utility model can also adopt following technical measures:
The output terminal of the described arm of force has elongate slots.
The end of described piston rod is provided with the piston contiguous block, and the piston rod bearing pin is installed on the piston contiguous block, and the piston rod bearing pin is inserted in the elongate slots that the output terminal of the arm of force has.
Advantage and the good effect that the utlity model has are: have breach owing to be installed in the input shaft lower end of test-bed crossbeam near arm of force place, arm of force bearing pin is installed in breach, arm of force bearing pin is installed on the arm of force, arm of force bearing pin on the input shaft drive arm of force rotates in the breach scope like this, has realized the purpose of part circle test; The arm of force drives piston rod movement by the piston rod bearing pin on the piston rod contiguous block, and piston rod drives the motion of hydraulic cylinder, for test mechanism provides required load; Be the opening and closing of the time control electric device for valve that satisfies the part circle test, be provided with in the both sides of test-bed upper arm and close positive stop and open the valve positive stop; Therefore said structure is simple, volume is little and the test of suitable small-bore part turning valve electric device; The utility model also has advantages such as test method is reasonable, easy to operate in addition.
