The working process and principle are as follows: the assembly line conveying mechanism 1 is provided with N stations, a large gear 7 and a small gear 8 (see figure 2) are arranged in front of each station, when a certain station in the preamble is found to be in operation leakage or unqualified in operation in a certain subsequent station, the transfer trolley 2 firstly enables the support mechanism 10 to quickly rise to the height of the assembly line conveying mechanism 1 (three insertion arms at the front end of the fork plate 20 are just inserted into a gap between the rollers 4, the width of the insertion arms is smaller than the width of the gap), then the refrigerator on the subsequent station is firstly moved onto the support mechanism 10 and quickly descends, a worker pushes the transfer trolley 2 to the front of the leakage operation station in the preamble and quickly rises, then the refrigerator is conveyed onto the assembly line conveying mechanism 1 by the support mechanism 10, the specific processes of ascending, descending and moving along the width direction of the rack 3 of the support mechanism 10 are as follows (for convenience of description, it is assumed that the conveying direction of the assembly line conveying mechanism, the bull gear 7 and the pinion gear 8 both rotate clockwise):

1. the supporting mechanism 10 quickly rises to the height of the assembly line conveying mechanism 1 and then moves along the width direction of the rack 3:

the transfer trolley 2 is pushed to the position behind the station near the pinion 8, the positioning groove 16 is inserted into the shaft of the pinion 8, at this time, the pinion 8 is meshed with the driven gearwheel 17 (the pinion 8 is not meshed with the driven pinion 30), therefore, the driven gearwheel 17 rotates anticlockwise, and because the driven gearwheel 17 is meshed with the driven pinion 30, the driven pinion 30 rotates clockwise to drive the rotating shaft 29, the first gear 31 and the second gear 32 to rotate clockwise, so that the rack 22 meshed with the first gear 31 is lifted, therefore, the lifting frame 21 is lifted, at this time, the roller 25 on the fork plate 20 is lifted along the vertical groove of the limiting groove 19 on the limiting plate 18, and the guide pillar 28 is lifted in the guide sleeve 27, when the roller 25 is lifted to the top end of the limiting groove 19, the height of the limiting plate 20 is represented to the height of the assembly line conveying mechanism 1, at this time, the third gear 34 is just meshed with the second gear 32 on the, meanwhile, the roller 25 starts to move along the transverse groove of the limiting groove 19, the lower end of the lifting frame 21 is connected in the sliding groove 24 on the supporting plate 23 in a sliding mode, therefore, the gear III 34 and the threaded rod I33 rotate anticlockwise, the sliding block I35 connected with the threaded rod I33 and the fork plate 20 connected above the sliding block I35 move forwards until the three insertion arms at the front end of the fork plate 20 are just inserted into gaps among the rollers 4;

2. the support mechanism 10 descends rapidly:

at the moment, the supporting mechanism 10 is at the highest position, the transfer trolley 2 is pushed to the position near the large gear 7 in front of the station, the positioning groove 16 is inserted into the shaft of the large gear 7, the large gear 7 is meshed with the driven pinion 30, the driven pinion 30 moves anticlockwise to drive the rotating shaft 29, the first gear 31 and the second gear 32 to rotate anticlockwise, but the rack 22 meshed with the first gear 31 cannot descend temporarily because the roller 25 is in the transverse groove of the limiting groove 19, meanwhile, the third gear 34 is meshed with the second gear 32 on the rotating shaft 29, the third gear 34 and the first threaded rod 33 rotate clockwise, so that the first sliding block 35 connected with the first threaded rod 33 and the fork plate 20 connected with the upper part of the first sliding block 35 move backwards until the roller 25 is separated from the transverse groove of the limiting groove 19, after the roller 25 enters the vertical groove of the limiting groove 19, the rack 22 meshed with the first gear 31 begins to descend, the ascending frame 21 descends, the roller 25 on the fork plate 20 descends along the limiting groove 19 on the limiting plate 18, and the guide post 28 descends in the guide sleeve 27, when the roller 25 descends to the bottom end of the limiting groove 19, the height of the fork plate 20 is the lowest.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes which come within the scope of or equivalence to the invention are intended to be embraced therein.
