Problems solved by technology

[0005] As an automated, intelligent, and unmanned product, AGV is often operated without workers. When the AGV lifts and transports goods, the market exceeds its safety threshold because the forks are too heavy at a certain height. Accidents that cause AGV to run unstable or roll

Embodiment 1

[0049] Example 1, such as figure 1 As shown, a safety height restriction system suitable for a cargo-carrying AGV and its operation method include a car body 91 . The carrier 92 can be a cargo fork, which is used to directly carry goods. The lifting device 1 is installed on the vehicle body 91 , and the AGV directly drives the lifting of the loading frame 92 through the operation of the lifting device 1 .

[0050] Specifically, in this embodiment, the lifting device 1 includes an oil tank 11 and a lifting cylinder 12 . The object carrier 92 can be directly connected on the door frame, and the lifting oil cylinder 12 is connected with the door frame to promote the lifting movement of the door frame.

[0051] The guiding device, positioning device, and walking device of the AGV can be directly used with reference to the components in the prior art, and no specific structural or functional changes are required in this case.

[0052] Such as figure 2 As shown, the AGV control...

Embodiment 2

[0071] Embodiment 2 is different from Embodiment 1 in that in this embodiment, the number of load sensors 7 and height sensors 8 is only one. The load sensor 7 has selected the liquid level sensor arranged inside the fuel tank 11, and the height sensor 8 has selected a pull switch.

[0072] Since there is only one load sensor 7 and one height sensor 8, the comparison process of T1 and T2 is omitted, and the comparison process of H1 and H2 is omitted, and the other methods are the same as in Embodiment 1.

[0073] The reason why the pull switch is used as the height sensor is that the pull switch is a mechanical measurement switch, and the working environment of the AGV often uses technologies such as magnetic strip guidance and laser positioning, and the mechanical measurement switch is not subject to electromagnetic interference and is not easy Due to the optical interference of the reflective glass on site, the performance is stable and reliable.

[0074] The reason for usi...

Abstract

The invention relates to the field of automated logistics, in particular to the mechanical design and system design of an AGV. The present invention is achieved through the following technical solutions: a safety height restriction system suitable for cargo-carrying AGVs, including a vehicle control system, a vehicle body, a loading frame and a lifting device that drives the loading frame to lift relative to the vehicle body, and also includes A height sensor for obtaining the current height H of the carrier and a load sensor for obtaining the current load T of the carrier. The purpose of the present invention is to provide a safety height limitation system and its operation method suitable for cargo-carrying AGV, which can effectively identify the height of the vehicle load, and evaluate the safety of the load at the current height, and effectively improve the operating status of the AGV. safety.

Description

technical field [0001] The invention relates to the field of automated logistics, in particular to the mechanical design and system design of an AGV. Background technique [0002] AGV (Automated Guided Vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical, which can drive along a prescribed guiding path. With the advancement of information technology and the maturity of automation level, the application of AGV is becoming more and more common, and it is widely used in various fields of handling, stacking and logistics. [0003] For example, the announcement number is CN201920154817.2, which discloses an AGV trolley. The AGV trolley includes automatic guidance and a power system to control the forward movement of the car body. AGV trolleys are often equipped with load-carrying parts such as forks, and the forks are driven up and down by power components such as oil cylinders. [0004] During the working process of...
