Description

Technical Field

[0001] The utility model relates to the technical field of logistics vehicles, and specifically to a safety limiting and fixing device for a smart logistics vehicle. Background Art

[0002] Smart logistics refers to a new logistics model that uses technologies such as artificial intelligence (AI), big data, and the Internet of Things to achieve automation, intelligence, and efficient collaboration in the logistics and transportation process, thereby improving operational efficiency and reducing costs. Smart logistics systems can effectively integrate various logistics resources and optimize transportation routes, vehicle utilization, warehouse management, and other aspects, thereby improving overall logistics service levels.

[0003] Smart logistics vehicles are indispensable in smart logistics. Smart logistics vehicles are vehicles that integrate multiple advanced technologies and can realize functions such as intelligent transportation, efficient distribution and unmanned operation. At present, smart logistics vehicles need to be limited and fixed when loading and unloading goods to prevent the vehicle body from moving and causing dangerous situations when transferring goods. However, the existing logistics vehicle limiting mechanisms are all fixedly installed in designated positions. The logistics vehicle needs to be moved to a smaller deviation from the designated position before it can be limited. Frequent movement of the vehicle affects the efficiency of cargo loading. Utility Model Content

[0004] The purpose of the present invention is to provide a safety limit fixing device for a smart logistics vehicle to solve the problems raised in the above background technology.

[0012] Preferably, a support rod fixedly connected to the fixing plate is provided on the outer side of the fixing frame.

[0013] Preferably, through holes for installing bolts are provided inside the fixing seat and the fixing plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] The intelligent logistics vehicle of the utility model reverses to the position of the fixed seat. When the wheel contacts the fixed frame, it indicates that the logistics vehicle has reached the position. Then, the limit hook is driven to rotate and rise in the mobile seat through the extension and contraction of the hydraulic rod. When the limit hook is hooked on the anti-collision beam of the logistics vehicle, the vehicle body is limited to prevent the vehicle body from moving and causing danger when the logistics vehicle is transferring goods. If the logistics vehicle has not stopped in place, there is no need to move the logistics vehicle. The worm is rotated by the rocker, and the worm is engaged with the worm gear to drive the worm gear to rotate. The worm gear drives the gear to rotate, and the worm gear moves in a straight line along the worm. At the same time, the gear moves on the tooth plate, driving the mobile seat to move on the fixed seat. The mobile seat moves the fixed assembly to the appropriate position, and then the fixed assembly is used to limit the vehicle body. BRIEF DESCRIPTION OF THE DRAWINGS
