Drawings

Fig. 1 is a schematic structural diagram of the present invention;

fig. 2 is a schematic structural diagram of a first connecting plate according to the present invention;

fig. 3 is a schematic structural diagram of the second connecting plate of the present invention.

In the figure: the method comprises the following steps of 1-a door machine driving motor, 2-a gear, 3-a car door, 4-an upper rack, 5-a lower rack, 6-a first connecting plate, 7-a second connecting plate, 8-a rectangular beam, 9-a rectangular groove, 10-a limit switch, 11-a doorsill, 12-a groove, 13-a roller, 14-a gravity sensor, 15-an adapter plate and 16-a rack groove.

Detailed Description

The invention is further described with reference to the accompanying drawings and the detailed description.

As shown in fig. 1, a rack and pinion type elevator door machine device comprises a door machine driving motor 1, a gear 2 is arranged at the output end of the door machine driving motor 1, racks are arranged above and below the gear 2, the racks are connected with a car door 3 through a connecting plate, the gear 2 is driven by the door machine driving motor 1 to drive the gear 2 to do circular motion, and the gear 2 drives the racks to do reciprocating linear motion, so that the car door 3 is opened and closed.

Installation of this implementation: the upper rack 4 is connected with the first connecting plate 6 through the adapter plate 15, and the first connecting plate 6 is connected with the car door 3; the lower rack 5 is connected with the other car door 3 through a second connecting plate 7, a threshold 11 is arranged below the car door 3, and a groove 12 is arranged in the threshold 11; two rollers 13 are arranged at the bottom of the car door 3, the rollers 13 are arranged in the grooves 12, meanwhile, the gravity sensor 14 is arranged in the grooves 12, and when the rollers 13 touch the gravity sensor 14, the car door 3 stops closing. A rectangular cross beam 8 is arranged below the lower rack 5, rectangular grooves 9 are formed in the first connecting plate 6 and the second connecting plate 7, the connecting plates are placed on the rectangular cross beam 8, a limit switch 10 is arranged on the rectangular cross beam 8, and when the connecting plates touch the limit switch 10, the car door 3 stops opening the door. The rack slot 16 is arranged in the adapter plate 15, so that the lower rack 5 can be prevented from colliding with the adapter plate 15 when moving.

The working mode of the implementation is as follows: when the elevator reaches the level set by the passenger, the door motor device opens the car door 3; firstly, a door machine driving motor 1 drives, a gear 2 is driven by the door machine driving motor 1 to run, an upper rack 4 is arranged above the gear 2, and a lower rack 5 is arranged below the gear 2, so that the gear 2 drives two racks to translate in different directions when rotating, opening of the car door 3 is realized, and when the connecting plate touches the limit switch 10, the opening process of the car door 3 is finished. When the car door 3 is opened, a passenger enters the car, the door motor device enables the car door 3 to be closed, when the car door 3 is closed, the door motor driving motor 1 works, the driving gear 2 operates, the operating direction of the gear 2 is opposite to the operating direction of the gear 2 when the car door 3 is opened, the movement of the rack drives the car door 3 to be closed, and when the roller 13 at the bottom of the car door 3 touches the gravity sensor 14, the closing process of the car door 3 is finished.

Compared with the traditional door machine device, if the belt of the door machine device is broken when the elevator works, the door machine can not be normally opened, and the passenger is trapped; if the car door 3 on one side of the door machine device cannot be opened, the connecting plate and the rack possibly fall off, but after the situation happens, the car door 3 on the other side is not influenced to be opened, and the passenger trapping event caused by the abnormal door machine can be avoided.
