Therefore, there is a need to develop a new door machine device, which is safer and more reliable to open and close the car door when the door machine motor is driven.
SUMMERY OF THE UTILITY MODEL
The utility model relates to an overcome current door machine transmission and pass through belt drive, when the belt skidded on the band pulley or the belt appears ageing cracked, all can influence opening of elevator sedan-chair door, provide a screw rod nut formula elevator door machine transmission.
In order to achieve the above purpose, the utility model adopts the following technical scheme: a screw nut type elevator door motor transmission device comprises a car door and a door motor driving motor, wherein the door motor driving motor is connected with a screw, and the other end of the screw is fixed through a support; the screw rod is provided with a plurality of nuts, the plurality of nuts are provided with connecting plates, and the connecting plates are connected with the car door.
Preferably, the number of the nuts is two, the two nuts are in the same rotating direction, the car door is one, and one car door is connected to the two connecting plates. The car door is connected through the two connecting plates, so that the connection is more reliable; simultaneously, the car door is arranged, so that the car door can be opened towards two sides in the application process, and the service life of the screw rod is prolonged.
Preferably, the number of the nuts is four, the car door is two, the two car doors are divided into a left car door and a right car door, and the left car door and the right car door are connected to the two nuts through two connecting plates. By utilizing the two car doors, passengers can be prevented from being trapped in the car when one car door fails.
Preferably, the nuts attached to the left and right doors are threaded in opposite directions. When the driving motor of the gantry crane runs, the running directions of the left car door and the right car door are opposite.
Preferably, a touch sensor is arranged on the side edge of the car door. When the two car doors are closed and the touch type sensor touches together, the driving motor of the gantry crane stops working.
Preferably, a car door placing groove is arranged below the car door, and limit switches are arranged on two sides of the car door placing groove. The opening degree of the two car doors on the car door placing grooves can be effectively controlled.
Preferably, the screw rod and the nut are arranged in the protective cover, and the protective cover is provided with an open slot. The screw and the nut are protected to prevent dust from entering.
The utility model discloses following beneficial effect has: (1) according to different structural requirements, one car door or two car doors can be selected; (2) when the car door is arranged on the lead screw, the service life of the lead screw can be properly prolonged; (3) the whole transmission device of the gantry crane has a simple structure.

FIG. 3 is a schematic structural view of a car door according to the present invention when closed;
FIG. 4 is a schematic structural view of the car door of the present invention when opened;
in the figure: the method comprises the following steps of 1-car door, 2-door machine driving motor, 3-screw, 4-bracket, 5-nut, 6-connecting plate, 7-touch sensor, 8-car door placing groove, 9-limit switch and 10-protective cover.
Detailed Description
The invention is further described with reference to the accompanying drawings and the detailed description.
A screw nut type door elevator transmission device comprises a car door 1 and a door machine driving motor, wherein the door machine driving motor 2 is connected with a screw 3, and the other end of the screw 3 is fixed through a support 4; the screw rod 3 is provided with a plurality of nuts 5, the plurality of nuts 5 are provided with connecting plates 6, and the connecting plates 6 are connected with the car door 1.
The below of sedan-chair door 1 all is equipped with sedan-chair door standing groove 8, and limit switch 9 is all installed to sedan-chair door standing groove 8's both sides, and limit switch 9 of installation is used for restricting the range of motion of sedan-chair door 1 on sedan-chair door standing groove 8. A protective cover 10 is arranged outside the screw rod 3 and the nut 5, an open slot is arranged on the protective cover 10, and the connecting plate 6 penetrates through the open slot of the protective cover 10 to be connected with the nut 5 on the screw rod 3.
Example 1: as shown in fig. 3 and 4, two nuts 5 are mounted on the screw 3, both the nuts 5 are connected to the connecting plate 6, and the car door 1 is connected to the connecting plate 6 while sharing one piece. In the application process, after the door machine driving motor 2 drives, the screw rod 3 rotates to drive the nut 5 to move on the screw rod 3, so that the car door 1 is moved.
