Forklift portal frame and safety protection system

Abstract

The invention provides a forklift portal frame and safety protection system. The forklift portal frame and safety protection system comprises a forklift portal frame, a frame base plate, a frame getting-off middle plate, a storage battery tray, a double-acting oil cylinder with a buffering function, a traveling controller and a lifting controller. A support I and a support II are further arranged on the forklift portal frame, and a portal frame position sensor I and a portal frame position sensor II are mounted on the support I and the support II correspondingly. A sliding rail position sensor is arranged on the frame base plate. A storage battery tray position sensor is arranged on the frame getting-off middle plate. The portal frame position sensor I is connected with the traveling controller through a circuit. The traveling controller is further connected with a traveling motor through a circuit. The portal frame position sensor II, the storage battery tray position sensor, and the sliding rail position sensor are all connected with the lifting controller through circuits. The lifting controller is connected with a lifting motor through a circuit. The traveling controller is in communication with the lifting controller through a CAN bus. According to the forklift portal frame and safety protection system, micro-control over the motors is achieved, and thus motion control of the portal frame and a whole forklift is achieved; and the structure is simple, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of forklifts, in particular to a forklift mast and a safety protection system. Background technique [0002] Forklifts are commonly used mechanical equipment in loading and unloading work. Among them, battery forklifts are used more and more for their advantages of low pollution and adaptability to many occasions. The power source is the battery assembled on the forklift. The lifting height of current forklifts is getting higher and higher, and the load capacity is also increasing. Although the transportation capacity has been improved, it also brings some unfavorable factors to the stability of forklifts, especially for some forklifts with high masts. , If the operation is too fast, it is easy to cause damage to the vehicle or even overturn, resulting in property and personal loss. Contents of the invention [0003] The purpose of the present invention is to provide a forklift mast and safety protection ...
