An AGV automatic lifting mechanism self-locking device

Abstract

The invention relates to an AGV (Automatic Guided Vehicle) automatic lifting mechanism self-lock device which comprises a speed reduction motor (1), a lifting bearing (3), a rotary disc (4), a telescopic pin (7), a self-lock spring (9) and limit bearings (11), wherein a lifting bearing pedestal (2) is arranged on one side of the speed reduction motor (1); the rotary disc (4) is mounted on the output shaft of the speed reduction motor (1); the lifting bearing (3) is mounted between the rotary disc (4) and the lifting bearing pedestal (2); an eccentric bearing (6) is mounted on one side of the rotary disc (4); the two limit bearings (11) are mounted on the other side of the rotary disc (4); a sleeve (8) is mounted at the lower part of the lifting bearing pedestal (2); the self-lock spring (9) is mounted in the sleeve (8); the upper end of the self-lock spring (9) is connected with the telescopic pin (7). The AGV automatic lifting mechanism self-lock device has the advantages that the stability is high, the self-lock performance is good, the self-lock torque is adjustable, and the problem that one group of driving wheel set cannot touch the ground so as to avoid slipping in the operational process of a unidirectional and bi-directional AGV is solved.

Description

technical field [0001] The invention relates to an unmanned transport vehicle, in particular to an AGV automatic lifting mechanism self-locking device. Background technique [0002] AGV is already a kind of logistics transportation equipment widely used in automated factories at home and abroad. The actual ground of the factory has some undulations and is not very smooth. Usually, the AGV's four-wheel landing is likely to cause the driving wheel to slip. [0003] At present, domestic AGVs are mainly one-way vehicles and two-way vehicles, and there is no AGV that can switch between one-way and two-way vehicles. Based on this, two sets of independent driving wheel sets and two sets of independent directional wheel sets need to be designed on the AGV, and each set requires an independent lifting mechanism. By switching the lifting of different wheel sets, one-way and two-way switching can be realized, which is convenient for responding to the actual operating space of the fa...
