The moving switching mechanism of torch is positioned at the transmission device below, by screw axis 23, be installed in the nut 22 on the screw axis 23, gear 21 and form at the latching device of screw axis 23 front ends, screw axis 23 is installed in the below of turbo-shaft 25 in the gear case 7, and it is parallel with turbo-shaft 25, its front end stretches out outside the gear case 7, end cross-sectional is square, nut 22 is installed in the latter half of of screw axis 23, gear 21 is sleeved on the nut 22 meshing with spline gear 24, and one be located in the pulling block 5, latching device is by spring 28, lock sleeve 30, lock 29 constitutes, spring 28 is enclosed within on the screw axis 23, the one end is fixed on the hubcap 27 of screw axis 23, the other end is fixed on the rear end of the lock sleeve 30 that is enclosed within on the screw axis 23, lock sleeve 30 is pre-small post-large, the cross section is circular in the rear portion, in the front portion, outer cross section is square, cross-sectional sizes and screw axis 23 end cross-sectional sizes were complementary in it was square, lock 29 is fixed on the guide plate 1, lock sleeve 30 fronts, one square opening is arranged on it, the outer cross-sectional sizes of this hole size and lock sleeve 30 front portions is complementary, in this hole of screw axis 23 front end sleeves, see Fig. 6, for cooperating the manual opening-closing of this invention, also be equipped with a rocking bar, rocking bar front end external diameter is less than the aperture on the moveable cart skull 12, and the centre hole of termination is square and is complementary with screw axis 23 front end sizes.
When carrying out shunting service, the driver makes the power control switch of the hood automatic opening-closing that is arranged in the locomotive cab place 1 (promptly opening the position), motor 8 clickwises, drive 35 rotations of coaxial driving gear, driving gear 35 passes to driven gear 6 with power, make driven gear 6 rotations and drive scroll bar 19 rotations, scroll bar 19 drives meshing with it turbine 18 again, turbine 18 drives turbo-shaft 25 rotations immediately, make the spline gear 24 that is installed on the turbo-shaft 25 with turbo-shaft 25 rotations, spline gear 24 is meshing with gear 21, thereby also rotation thereupon of gear 21, because gear 21 is fixed together with nut 22, and be installed on the screw axis 23, therefore, in both rotation time, are straight-line motion backward again, again because spline gear 24 and nut 22, gear 21 is enclosed within the pulling block 20 together, so four moving linearlies backward together, pulling block 20 is along guide groove 26 translation backward of gear case 7, and drive tranverse connecting rod 4 and move after parallel, spur the diagonal control arm 3 that is attached thereto thus, drive slide block 15 along guide groove 2 to side, slide in the back, along with slide block 15 to side, move at the rear, slide bar 16 is that open to the left and right sides at the center with central pin shaft 17 gradually, the final moveable cart skull 12 that drives moves to the left and right sides, enters fixedly hood 11 inboards, makes outside hitch 33 is exposed to fully, make things convenient for shunting service, when moveable cart skull 12 entered fixedly in the hood 11 fully, travel switch of in-to-in made motor 8 dead electricity, and motor 8 stops the rotation.
After shunting service finishes, the driver makes the power control switch of the hood automatic opening-closing of device in locomotive cab place 2 (promptly disconnected positions), motor 8 beginning left-hand revolutions, the driving gear 35 that drive is attached thereto, driven gear 6, scroll bar 19, turbine 18, turbo-shaft 25 contrarotations, make the spline gear 24 that is installed on the turbo-shaft 25 with turbo-shaft 25 rotations, and driven gear 21, nut 22 rotations, simultaneously, move forward gradually, it is anterior mobile to gear case 7 along the guide groove on the gear case 7 26 to drive pulling block 5, thereby make tranverse connecting rod 4 parallel reaches, promote the diagonal control arm 3 be attached thereto thus, thereby promote slide block 15 along guide groove 2 in, slide in the place ahead, along with slide block 15 in, move in the place ahead, and slide bar 16 closes up for middle mind-set center with central pin shaft 17 gradually, the final moveable cart skull 12 of driving moves to the middle part, when moveable cart skull 12 is closed fully, another travel switch dead electricity of in-to-in, motor 8 stops the rotation.In said process, the front end of lock sleeve 30 tightly is enclosed within the square hole of lock 29 always, and promptly the manual opening-closing mode is in locking states.
When locomotive is in electroless state,, then can carry out manual operation if need open moveable cart skull 12 is engaged in shunting service.At first, in the aperture on the end insertion moveable cart skull 12 of rocking bar, make it be enclosed within screw axis 23 front ends, firmly push inward, make spring 28 compressions, lock sleeve 30 is discharged from the square hole of lock, then turn an angle, lock sleeve 30 is withstood on the lock back side, and screw axis 23 can rotate, and so just electronic opening/shutting mode is changed for the manual opening-closing mode.Then, cw shakes rocking bar, screw axis 23 clockwise rotates, because the lead angle of scroll bar 19 is less than 3.5 °, therefore its motion can not make turbine 18 drive scroll bar 19 rotations, so turbo-shaft 25 does not rotate, can only be that spline gear 24 moves on turbo-shaft 25 backward, therefore, screw axis 23 clockwise rotates the feasible nut 22 that is installed on the screw axis 23, gear 21 moves to gear case 7 rear ends, drives pulling block 5 and moves backward, and the spline gear 24 that is in the pulling block 5 also should move simultaneously backward, equally, this moment pulling block 5 after move the pulling tranverse connecting rod 4, diagonal control arm 3, slide 15, making slide bar 16 is that open to the left and right sides at the center with central pin shaft 17, finally drives moveable cart skull 12 and moves to the left and right sides, enter fixedly hood 11 inboards, make outside hitch 33 is exposed to fully.
When will be when electroless state be closed moveable cart skull 12, only need rocker sleeve at screw axis 23 front ends, conter clockwise shakes rocking bar, the same process, moveable cart skull 12 will be closed.After moveable cart skull 12 closures, holding rocking bar firmly pushes inward gently, turn an angle, make lock sleeve 30 front ends behind the square hole of lock 29, applied thrust no longer, at this moment, lock sleeve 30 its front end under the effect of spring force sinks in the square hole of lock 29, takes off rocking bar and promptly crosses complete whole closing course.
