Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
As shown in fig. 1, 2 and 3, a door machine transmission mechanism comprises a door machine driving motor 1, a door machine transmission device, a driving roller group 2 and a car door; the gantry crane transmission device comprises a gear 3 and a rack 4, and the car door comprises a movable car door 5 and a fixed car door 6; the rack 4 is connected with the driving roller group 2, and the driving roller group 2 is connected with the movable car door 5; the driving motor 1 of the gantry crane drives the gear 3 to do circular motion, the gear 3 drives the rack 4 to do reciprocating linear motion, the rack 4 drives the driving roller 10 to move, and the driving roller 10 drives the movable car door 5 to open and close.
The driving roller groups 2 are provided with two groups in total, the rack 4 is fixed on one driving roller group 2, and one end of the rack 4 is connected with the other driving roller group 2 through a connecting plate A7. The movable car door 5 is driven to be opened and closed through the two groups of driving roller groups 2, so that the movable car door 5 can be more stable when being opened and closed.
The driving roller group 2 is connected with the movable car door 5 through a connecting plate B8. The driving roller set 2 and the movable car door 5 can be stably connected conveniently.
The two groups of driving roller groups 2 are respectively arranged in the two groups of roller moving grooves 9, one group of roller moving grooves 9 has two sections, and an included angle of 120-150 degrees is formed between the two sections of roller moving grooves 9; an open slot is arranged on the roller moving slot 9. The angle between the two roller moving grooves 9 can facilitate the driving of the roller group 2 to steer, so that the running track of the movable car door 5 is determined, the opening and closing of the movable car door 5 are facilitated, and meanwhile, the open groove can prevent the phenomenon that the connecting plate B8 collides with the roller moving grooves 9 when the movable car door 5 moves.
