Embodiment
Combine accompanying drawing that the present invention is done further detailed explanation now.These accompanying drawings are the synoptic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Like Fig. 1 is the structural representation of separating brake trip assembley therefor.
Breaker brake-separating and tripping force test device like Fig. 2, Fig. 3, preferred forms shown in Figure 4; Has support 1; Support 1 top movable is connected with the fixedly rotating lever 2 of workpiece for measurement; Support 1 bottom is provided with and drives the power energy storage device that rotating lever 2 rotates, and support 1 top is provided with and promotes the propulsion test device that workpiece for measurement is threaded off, and is set with the backstay 5 that workpiece for measurement is positioned near rotating lever 2 places on the support 1.
The power energy storage device comprises energy storage handle 31, drives the gear train of running and the storage capacity meter 32 that gear train drives motion by energy storage handle 31; Storage capacity meter 32 is selected the thrust meter of 1000N for use; Storage capacity meter 32 upper ends are fixed with and drive the push rod 33 that rotating lever 2 rotates; Gear train comprises and is connected on the energy storage handle 31 tooth bar 342 assemblies that are connected with a joggle by the gear 341 of energy storage handle 31 driven rotary, with gear 341; Tooth bar 342 assemblies are tooth bar 342 and are fixed on the slide block 343 on the tooth bar 342, through sliding in the guide rail of slide block 343 on being opened in support 1, realize moving of push rod 33; Peak on the rotating lever 2 through push rod 33, rotating lever 2 is rotated.
Propulsion test device comprises free-handle 41, is driven the separating brake dropout dynamometer 42 of motion by free-handle 41; Separating brake dropout dynamometer 42 is selected the dynamometer of 30N for use; Separating brake dropout dynamometer 42 tops are fixed with and promote the push rod 43 that workpiece for measurement is threaded off; Separating brake dropout dynamometer 42 is installed on the slide plate, and slide plate is the slide rail operation on the support 1, and the free-handle that moves through of slide plate drives.
The present invention is fixed in workpiece for measurement on the rotating lever 2 earlier, is positioned by backstay 5, rotates through rotating energy storage handle 31 driven gears 341 then; Through the engagement of gear 341, make tooth bar 342 move along a straight line, because tooth bar 342 is fixed on the slide block 343 with tooth bar 342; Slide block 343 has fixed track, and track is the guide rail on the support 1, so because the rectilinear motion of tooth bar 342; Make slide block 343 slide along guide rail; The storage capacity meter of on slide block 343, fixing 32 is movement therewith also, thereby makes the push rod 33 on storage capacity meter 32 terminations together move, and withstands on the rotating lever 2 through push rod 33.Calculate the certain power of rotating lever 2 that provides by storage capacity meter 32 as required; In this process, be provided with self-locking handle owing to dynamic test device lower end; Be with spring on the handle bar of handle, the front end of handle stem is fixed with the self-locking wedge, through the self-locking wedge under the effect of spring force; Make the inclined-plane of self-locking wedge and the arc surface of tooth bar 342 assembly slide blocks 343 lower ends keep in touch constantly and self-locking constantly; When the power value that shows when the 1000N dynamometer reaches required energy storage power, unclamp energy storage handle 31, self-locking this moment wedge locking storage ability value makes the separating brake trip assembley therefor be in energy storage and snap close state.
Rotate free-handle 41; Make slide plate along the slide rail rectilinear motion; Driving separating brake dropout dynamometer 42 moves; Thereby make push rod 43 promote the dropout lever of separating brake trip assembley therefor by certain position and direction, make the separating brake trip assembley therefor realize threading off, the numerical value on this moment 30N dynamometer is the actual brake-separating and tripping force of separating brake trip assembley therefor.
Thereby drawing back arc surface that self-locking handle makes self-locking wedge and tooth bar assembly at last separates to make the release of 1000N thrust meter and reset and measures so that prepare next time.
