Detailed Description

The present invention will be further explained with reference to the accompanying drawings and examples.

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

Referring to fig. 1, the present embodiment provides a device for preventing goods from falling, which includes a fixing bracket 1, a rotating bracket 2, a driving module 3, a distance measuring module 4, an alarm module, and a controller; the controller is connected with the driving module and the alarming module respectively.

The fixed bracket 1 is arranged at two sides of a goods taking device (such as a fork 5 shown in figure 1), and the rotating bracket 2 is arranged on the fixed bracket 1; each fixed support 1 is provided with a driving module 3, and the driving module 3 is used for driving the rotating support 2 to rotate under the control action of the controller; the distance measuring module 4 is arranged on the rotary bracket 2 and used for measuring the distance between the goods placing device and the pallet goods and transmitting the measurement result to the controller; and the alarm module is used for receiving the cargo falling early warning signal output by the controller.
