Embodiment
As shown in Figure 1 and Figure 2, this switch cabinet handcart Qu Jin mechanism includes a pair of being arranged on vehicle frame 01 and to cooperatively interact the worm gear 02 of transmission and worm screw 03; Worm screw rotating shaft 031 is positioned at horizontal level, and worm screw rotating shaft outboard end is provided with to match with operating grip 07 and merges the operating side 032 of transmitting torque; Worm wheel shaft 021 is positioned at vertical position, and the lower end of worm wheel shaft is connected with the actuating arm 04 that can rotate with worm wheel shaft, and actuating arm front end is provided with roller 05; As shown in Figure 3, Figure 4, roller is limited in a fixed guide 06, roller 05 can interact with fixed guide 06 with in actuating arm 04 swing process, and then the vehicle frame 01 of worm wheel shaft 021 and handcart can be driven with the cabinet relative movement of switch cubicle and the position that enters or deactivate.
As shown in Figure 5, Figure 6, described operating grip 07 has one can promote its sliding sleeve 072 in axial sliding by action bars 071 with the abutting end cover of worm screw rotating shaft 031, and the front end of sliding sleeve is provided with one section of conical surface 073, and conical surface back segment has one section of annular groove 074; As shown in Fig. 1, Fig. 6, sliding sleeve arranged outside has an interlocking segment 08, and interlocking segment is fixedly connected on blocking lever 09 front end, and blocking lever 09 rear end is hinged on vehicle frame 01 by jointed shaft 10 and also can upper and lowerly swings; Interlocking segment 08 has the chimb 081 corresponding with the conical surface position on above-mentioned sliding sleeve, also there is the grab 082 aiming at described annular groove 074; At operating grip 07 with under operating side 032 mated condition of worm screw rotating shaft, during described sliding sleeve 072 forward slip, the conical surface 073 can be oppressed chimb 081 and make interlocking segment 08 and blocking lever 09 to lower swing, and described interlocking segment 08 can be stuck in described annular groove 074 to grab 082 described during lower swing and to limit the operating side 032 that sliding sleeve 072 and whole operating grip 07 axially exit worm screw rotating shaft 031; Described blocking lever 09 is also connected with a lock pin 12 by a linkage board 11, lock pin 12 be limited in one with the relatively-stationary vertical pilot hole 13 of vehicle frame in and can move up and down with the swing of blocking lever 09, the upper end of lock pin 12 stretch out pilot hole 13 and and be provided with one applies upwards active force spring 14 to lock pin 12 between pilot hole end face; When worm gear 02 rotates to test position and service position, described spring 14 can drive and lock pin 12 moves and inserts lockhole 022 corresponding on worm gear 02 end face respectively; When worm gear 02 is rotated between test position and service position, the bottom surface that described lock pin 12 upper end withstands on worm gear 02 overcomes spring force and remains on lower position.
The operating process of the embodiment of the present invention is as follows:
When worm gear is positioned at test position (as Fig. 1), operating grip 07 shown in Fig. 5 is inserted the operating side 032 of worm screw rotating shaft 031, sliding sleeve 072 is driven to move forward by action bars 071, the conical surface 073 of sliding sleeve front end is made to oppress the chimb 081 of interlocking segment 08, interlocking segment is moved down, and then drive blocking lever 09 and lock pin 12 to move down, lock pin is exited from the lockhole 022 worm gear, now rotating operating handle can drive worm screw and worm gear to rotate, and then drive actuating arm 04 to change with the relative position of fixed guide 06, worm wheel shaft 021 and vehicle frame 01 is made to move to service position from test position,
In above process, when interlocking segment 08 is depressed by sliding sleeve 072, grab 082 on interlocking segment is stuck in annular groove 074, and by test position in the process of service position, because lock pin 12 is positioned at lower position, thus the position that blocking lever and interlocking segment keep down is made, make grab 082 remain in draw-in groove, thus operating grip cannot exit, until after the position that lock pin 12 arrives lockhole 022 upsprings again, operating grip just can exit, thus ensure that reliable interlocking.
