The beneficial effects of the utility model are: when needing circuit breaker to adjust to closing position by open position, splined hole spline on splined spanner is sheathed on the spline spindle of circuit breaker, the linearly operating output of driving mechanism exports linearly operating thus drives bearing pin to slide in the connection elongated hole of splined spanner, bearing pin drives the axis of splined spanner lap-ups keyhole to rotate, spline spindle rotates with splined spanner, thus circuit breaker is adjusted to closing position, because linearly operating output can move the locking that puts in place, so when circuit breaker arrives closing position, the motion of linearly operating output is stopped to be positioned closing position by circuit breaker, facilitate the installation of corresponding switching-in spring.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model;
Fig. 2 be in Fig. 1 shifting axle and cored screw coordinate schematic diagram.
Embodiment
The embodiment of circuit breaker auxiliary switching-in instrument is as shown in Figure 1 and 2: comprise splined spanner 1 and tool rack, one end of splined spanner is provided with the splined hole be sheathed on for spline on the spline spindle 10 of respective circuit breakers, and the other end of splined spanner is provided with the length bearing of trend connection elongated hole 15 consistent with splined spanner length bearing of trend.The connecting plate 2 for being connected with the housing of circuit breaker that tool rack extends after comprising plate along the vertical direction, connecting plate is provided with driving mechanism, driving mechanism has can export above-below direction linearly operating and motion puts in place the linearly operating output of locking, driving mechanism comprises the female swivel nut 6 of tool that the axis be fixedly arranged on connecting plate extends along the vertical direction, linearly operating output comprises the cored screw 5 of spinning in swivel nut and the shifting axle 4 be arranged in the endoporus of cored screw, the upper end of shifting axle is provided with and turns edge 12 outward, the endoporus of cored screw 5 is shoulder hole, shoulder hole has macropore section setting up and down and aperture section, turn edge outward and 12 be arranged in macropore section, shifting axle 4 is threaded onto in aperture section, turn edge outward between 12 and the step surface 11 of shoulder hole and be provided with thrust bearing 3, macropore section is provided with spanner perforation 13 outward in the upside turned edge, spanner perforation constitutes the moment of torsion input structure for moment of torsion input.The lower end of shifting axle is provided with bearing pin 9 by U-shaped part 7, the axis of bearing pin and the axis being parallel of splined hole, U-shaped part comprises diapire and spaced two side, diapire is fixedly welded on shifting axle, bearing pin is arranged in the pin-and-hole 14 of the two side of U-shaped part, bearing pin is arranged in and connects in elongated hole 15 to connect slip in elongated hole when linearly operating output exports linearly operating thus to drive the axis of splined spanner 1 lap-ups keyhole to rotate simultaneously, bearing pin is provided with block card 8 in the both sides of U-shaped part, and block card can prevent bearing pin from deviating from by U-shaped part.
Motion in the utility model locking that puts in place refers to after shifting axle moves to a certain position, when the power of driving mechanism disappears, shifting axle is just locked in this position and can not moves up and down, and shifting axle realizes putting in place locking by being threaded between swivel nut with cored screw in the present embodiment.The use procedure of auxiliary switching-in instrument of this circuit breaker is, when circuit breaker is adjusted to closing position by open position by needs, because circuit breaker does not also install switching-in spring, therefore the adjustment of circuit breaker can only be realized by aid, by bolt, connecting plate is fixed on the housing of circuit breaker, splined hole spline on splined spanner is set on the spline spindle of circuit breaker, a force spanner is installed in the spanner perforation of cored screw, then rotation urging spanner, cored screw moves upward in swivel nut, the step surface of shoulder hole drives shifting axle to move upward by thrust bearing, simultaneously due to the effect of thrust bearing, shifting axle only axially moves and non rotating, shifting axle drives bearing pin to move upward, bearing pin is connecting slip in elongated hole thus is driving the axis of splined spanner lap-ups keyhole to rotate, spline spindle rotates with splined spanner, when circuit breaker arrives closing position, stop to cored screw input torque, under the self-locking of screw thread, cored screw and shifting axle are all by locking, circuit breaker is also located in closing position, to carry out the installation of switching-in spring.In Fig. 1, double dot dash line represents the present position of circuit breaker splined spanner when open position, and solid line represents the present position of circuit breaker splined spanner when closing position.
In other embodiment of the present utility model: U-shaped part also can not be established, now bearing pin can directly be arranged on shifting axle; Connecting plate can not also be directly fixed on the housing of circuit breaker, such as is fixed on assembly platform by circuit breaker, is also fixed on assembly platform by connecting plate, as long as ensure that connecting plate is relative with the housing of circuit breaker fixing; Connecting plate can also be other structures such as framework; Spanner perforation can also be replaced by other moment of torsion input structures such as outer square shaft, interior square holes; Driving mechanism can also be a screw-nut mechanism, and screw is as moment of torsion input component, and leading screw can export the linearly operating on above-below direction, and bearing pin is arranged on leading screw, and the threaded engagement now between leading screw and screw can realize the locking that guide screw movement puts in place; Certainly, driving mechanism can also be this kind of lockable mechanism that puts in place that has linearly operating output and linearly operating output can move such as cylinder, hydraulic cylinder, the piston rod of cylinder, hydraulic cylinder is linearly operating output, after piston rod stretches out, the gas in cylinder and the liquid in hydraulic cylinder all can make piston rod movement put in place locking.
