Problems solved by technology

[0004] In the existing technical solution, the lead screw in the lifting drive assembly is rigidly connected to the lift actuator. When the lifting platform of the lift actuator generates an unbalanced load under load, the unbalanced load will directly act on the lead screw. above, making the lead screw and nut pairs suffer from severe stress conditions and reducing their service life

Embodiment Construction

[0029] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] It should be clear that the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] This embodiment provides a lifting device, which is used in equipment that lifts goods to a certain height, such as in an AGV. The AGV includes a chassis, and wheels are arranged on the lower part of the chassis. The chassis can be equipped with automatic guiding devices such as electromagnetic or optical to drive the AGV along the guiding path, and the lifting device can be arranged on the chassis. In the following, it will be described by taking the lifting device applicable to an AGV as an example.

Abstract

The invention discloses a lifting device, relates to the technical field of automated guided vehicles, and can prolong the service life of a lead screw. The lifting device comprises a lifting executing assembly and a lifting driving assembly. The lifting driving assembly comprises a driving motor, a vertically-arranged lead screw, a nut arranged on the lead screw in a sleeving mode and a nut limiting assembly for limiting the nut to move up and down, and the driving motor is connected with the nut through a transmission mechanism, and the top end of the lead screw is rotatably connected with the lifting execution assembly. The lifting device is suitable for occasions where the automated guided vehicles is used for lifting goods.

Description

technical field [0001] The invention relates to the technical field of automatic guided transport vehicles, in particular to a lifting device on the automatic guided transport vehicles. Background technique [0002] Automated Guided Vehicle (AGV, Automated Guided Vehicle) refers to a transport vehicle equipped with automatic guidance devices such as electromagnetic or optical. The tractor belongs to the category of wheeled mobile robot (WMR, Wheeled Mobile Robot). [0003] In order to realize the handling and lifting of goods, some AGVs are equipped with lifting devices. The lifting device generally includes a lifting actuator assembly and a lifting driving assembly; the lifting driving assembly is driven by a screw nut pair, and the top end of the screw is rigidly connected to the lifting actuator assembly. [0004] In the existing technical solution, the lead screw in the lifting drive assembly is rigidly connected to the lift actuator. When the lifting platform of the l...
