In the process that the split type trolley 4 slides on the track 3, the trolley slides on the platform and then presses the limiting rod 23, the sliding block 22 compresses the seventh compression spring 24 under the action of the limiting rod 23, so that the energy storage state is realized, and when the trolley finally stops, the energy storage is at the maximum value.

At this time, the engine is started, so that the power of the engine 51 is transmitted to the upper belt pulley 53 through the engine belt pulley 52 and the belt 55, the first bevel gear 461 and the upper belt pulley 53 are tightly attached, so that the first bevel gear 461 is also provided with power, the fifth bevel gear 472 and the third bevel gear 464 are engaged while the fifth bevel gear 472 and the fourth bevel gear 465 are completely disengaged, the power is transmitted to the fifth bevel gear 472, the back-washing motor is driven to operate in a reverse direction, and the battery 48 is charged.

When the split-type trolley 4 needs to be lowered, the left side of the rotating plate 452 is stepped by a foot, under the action of the middle first rotating shaft 454, the other rotating plate 452 is lifted upwards to push against the connecting plate 444 of the locking device 44, the connecting plate 444 is driven to be lifted upwards, so that the first locking boss 442 and the second locking boss 447 upwards slide out of the first locking hole 62 and the second locking hole 63 of the trolley body 6, the transmission device 46 slides outwards in a linkage manner, the locking plate 492 slides outwards along with the transmission device 46 under the action of the fifth compression spring 491 and the sixth compression spring 493, the effect of unlocking the reel device 42 is achieved, under the effect of the seventh compression spring 24, the limiting rod 23 is pressed to contact the split-type trolley 4, the trolley is enabled to slide outwards along the guide rail 3, and the trolley automatically falls down.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
