Lifting mechanism of laser navigation forklift and accurate control system

Abstract

The invention discloses a lifting mechanism of a laser navigation forklift and an accurate control system. The lifting mechanism of the laser navigation forklift comprises a hydraulic lifting column installed on the surface of the bottom of a forklift body of a right-angled-U-shaped structure, a lifting frame connected with the forklift body is installed at the end, away from the forklift body, of the hydraulic lifting column, and a pallet fork is installed on the lifting frame. Through a pressing column strip and an oil liquid speed limiting block, the descending speed and shaking amplitude of the lifting frame are reduced, during implementation, the lifting frame can be pulled to be lowered by lowering the height of the hydraulic lifting column, and then a hydraulic push column is filled with liquid through a movable liquid filling device, so that the pressing column strip is pushed to press the lifting frame to lower the descending speed and the shaking amplitude of the lifting frame. Meanwhile, when liquid in the hydraulic lifting column starts to be discharged, the oil liquid speed limiting block can be driven to be inserted into a liquid filling channel so as to limit the suction speed of the liquid in the hydraulic lifting column, the reduction speed of the hydraulic lifting column is stable, and therefore the situation that a lifting mechanism is damaged and leaks oil due to the fact that the lifting mechanism is subjected to large instantaneous impact force can be avoided.

Description

technical field [0001] The invention relates to the technical field of forklift lifting, in particular to a lifting mechanism and a precise control system of a laser navigation forklift. Background technique [0002] In the existing warehouse site, an intelligent three-dimensional warehouse for gypsum boards is established, so that gypsum board products with barcodes can be automatically stored in the warehouse by using laser navigation forklifts; at the same time, the sales data is transmitted to the warehouse management system, and the laser navigation forklifts receive the data and automatically Transport plasterboard from warehouse to dispatch. To realize the intelligent and unmanned management of the gypsum board warehouse, laser navigation forklifts play a very important role in this process. [0003] Laser navigation is composed of car body, navigation system, data acquisition system and communication system, among which the more important structure is the lifting me...
