Flexible lifting device and robot chassis comprising same

Abstract

The embodiment of the invention discloses a flexible lifting device and a robot chassis comprising the same. The device comprises at least one lifting chain, wherein each lifting chain is correspondingly provided with a lifting motor and a winding and unwinding motor, the lifting chain comprises a plurality of chain links, the chain links are connected end to end through rotatable shaft pins, the chain links are hollow, one end of the lifting chain is a lifting end, and the other end of the lifting chain is a winding and unwinding end; the lifting motors are connected with the lifting chains and used for controlling the lifting chains to ascend and descend, and the lifting ends are driven by the lifting motors to ascend and descend between a preset first height and a preset second height in the first direction; and the winding and unwinding motors are connected with the winding and unwinding ends and used for winding and unwinding the lifting chains in the clockwise or anticlockwise direction in the lifting process of the lifting chains. According to the flexible lifting device and the robot chassis comprising the same, the lowest height of the lifting device is reduced, the occupied space of the lifting device is reduced, and the lifting flexibility is improved.

Description

technical field [0001] The present application relates to the technical field of flexible lifting devices, in particular to a flexible lifting device and a robot chassis including the same. Background technique [0002] In many applications, a lifting device is required. For example, many robot chassis need to use a lifting device to control the lifting of parts carried by the robot. A common robot lifting device uses a single-axis slide rail to form a lifting component on the chassis, and usually a single-axis slide rail is always erected and fixed on the chassis. [0003] However, since the single-axis slide rail is a rigid structure, it cannot be stored, which will cause the minimum height of the lifting device to remain at a relatively high height after the robot is stored, and the maximum lifting height of the robot cannot exceed the maximum height of the slide rail. Lifting height, poor controllability of lifting height. In addition, when the robot equipment needs po...

Problems solved by technology

[0003] However, since the single-axis slide rail is a rigid structure, it cannot be stored, which will cause the minimum height of the lifting device to remain at a relatively high height after the robot is stored, and the maximum lifting height of the robot cannot exceed the maximum height of the slide rail. Lifting height, poor controllability of lifting height

In addition, when the robot equipment needs power supply from the robot chassis or wired data transmission with the chassis, it is necessary to install additional wiring brackets, and it is necessary to take into account the reciprocating range of the slider and the size of the load, which makes the structure of the lifting device complex and takes up a lot of space. It is easy to install and maintain, and it is easy to get stuck when lifting, and the lifting flexibility is poor
