Lifting mechanism of fork truck

Abstract

The invention provides a lifting mechanism of a fork truck. The lifting mechanism comprises a base; a first upright column and a second upright column in the vertical direction are arranged on the two sides of the base respectively; a first lifting cover is slidingly arranged on the first upright column; a first goods fork is hinged to the lower part of the first lifting cover; a second lifting cover is slidingly arranged on the second upright column; a second goods fork is hinged to the lower part of the second lifting cover; a first near-end pressure sensor and a first far-end pressure sensor are arranged on the first goods fork; and a second near-end pressure sensor and a second far-end pressure sensor are arranged on the second goods fork. The lifting mechanism is simple in structure and reasonable in design; the first goods fork and the second goods fork are independently controlled, whether the gravity center of goods on the first goods fork and the second goods fork is stable is monitored through the first near-end pressure sensor, the first far-end pressure sensor, the second near-end pressure sensor and the second far-end pressure sensor, and a controller adjusts the relative height between the first goods fork and the second goods fork or respective inclination angles of the first goods fork and the second goods fork according to measurement data of the various pressure sensors.

Description

Technical field [0001] The invention relates to the technical field of machinery, in particular to a lifting mechanism of a stacker. Background technique [0002] Stacker trucks are mainly used for cargo handling and stacking, and are widely used in factories, warehouses, docks and many other places where cargo needs to be loaded and unloaded. It has the advantages of convenient operation and high efficiency. [0003] When in use, the handle assembly is used to control the drive assembly to realize the traveling and turning operations of the stacker, and the handle assembly can also be used to control the drive assembly to control the mast assembly to load and unload and transport the goods. , Stacking and other operations. However, the stackers currently on the market also have some problems. In the mast assembly, the forks can only be fixed at one angle and cannot be adjusted. Generally, they are kept in a horizontal state, so that the goods are easily affected by vibration duri...

AI Technical Summary

Problems solved by technology

[0004] The invention proposes a lifting mechanism of a stacker, which solves the problems in the prior art that the forks of the stacker cannot be adjusted, and the goods are easy to detach, causing potential safety hazards
