1. An automatic transport device for conveying a shelf to a transport platform of a cleaning machine, comprising:
a transport base;
a lifting-lowering assembly;
a tray; and
a translation assembly;
wherein the lifting-lowering assembly and the tray are provided on a top of the transport base; the tray is connected to the transport base through the lifting-lowering assembly; and the lifting-lowering assembly is configured to drive the tray to reciprocate in a height direction of the tray;
a top surface of the tray is provided with the translation assembly; and the translation assembly is configured to receive and transfer the shelf to the transport platform;
a first end of the tray and a second end of the tray opposite to the first end of the tray are each provided with a first mounting cavity; and the translation assembly is connected to a side wall of the first mounting cavity;
a third end of the tray and a fourth end of the tray opposite to the third end of the tray are each provided with a second mounting cavity; the second mounting cavity is provided with a limiting assembly, a lifting-lowering sensing assembly, and a distance sensing assembly; the lifting-lowering sensing assembly is configured to position a height of the transport platform; the distance sensing assembly is configured to measure a distance between the transport device and the transport platform; and the limiting assembly is configured to limit a position of the shelf,
an interactive system is provided in the transport base; and the lifting-lowering assembly, the translation assembly, the lifting-lowering sensing assembly, the limiting assembly, and the distance sensing assembly are electrically connected to the interactive system;
the limiting assembly comprises a mounting plate; and a first fixing base, a second fixing base, a third fixing base, a stopper rod, a linkage rod, and an electromagnetic device are provided on the mounting plate;
the stopper rod passes sequentially through a top surface of the second mounting cavity, the first fixing base and the second fixing base; the stopper rod is provided with a first limiting ring; the first limiting ring is located between the first fixing base and the second fixing base; and the stopper rod is sleevedly provided with a first spring, and the first spring is located between the second fixing base and the first limiting ring;
a lower end of the stopper rod is connected to the electromagnetic device through the linkage rod; the linkage rod is provided with a fixing member; and the linkage rod is connected to the mounting plate through the fixing member;
the electromagnetic device is mounted on the third fixing base; a lower end of the electromagnetic device passes through the third fixing base; the lower end of the electromagnetic device is sleevedly provided with a second spring and a second limiting ring; and the third fixing base and the second limiting ring are configured to limit the second spring; and
the lower end of the electromagnetic device is configured to reciprocate along a height direction of the electromagnetic device, so as to drive the stopper rod to reciprocate in a height direction of the stopper rod.
