Mining robot omni-directional detection mechanical arm

Abstract

The invention relates to the field of robots, in particular to a mining robot omni-directional detection mechanical arm. The mining robot omni-directional detection mechanical arm comprises a fixing mechanism, a steering mechanism, an extension mechanism and a detection mechanism. Through the clamping effect between a convex cake groove in an adapter sleeve ring and an anti-falling circular plate at one end of a rotating main shaft, it can be guaranteed that the displacement of a rotating main shaft can be adjusted through the driving force of a pneumatic cylinder, meanwhile, angle adjustment of the rotating main shaft is not affected, the anti-falling circular plate at the front end of the rotating main shaft can rotate in the convex cake groove, and the adapter sleeve ring does not rotate along with the rotating main shaft; the position of an inner sleeve sliding rod is controlled through the connection state between a synchronous sleeve and a synchronous bevel gear, and then the length of the extension mechanism is controlled, so that the detection range of the mechanical arm is controlled; when the inner sleeve sliding rod contracts, the mechanical arm is small in overall size, direction adjustment is facilitated, and the detection range is large; and when the inner sleeve sliding rod extends, the detection depth of the mechanical arm is large, detection can be conducted more accurately, and meanwhile the mechanical arm can extend to a narrow space for detection.

Description

technical field [0001] The invention relates to the field of robots, in particular to an all-round detection mechanical arm of a mining robot. Background technique [0002] Mineral resources, as widely used and highly demanded energy sources, require a large amount of mining and transportation every year. Because mineral resources are located deep underground, it is necessary to dig channels to the ground for detection and mining, but the geology of the mineral resources is different. , It is very dangerous to manually detect and mine underground, so it is necessary to use mining robots instead of manual to conduct preliminary detection of mine conditions. [0003] Existing mining detection manipulators mostly adopt the multi-joint folding method. However, the expansion and contraction of the multi-joint manipulator requires certain three-dimensional space requirements, and at the same time, the front-end joints cannot achieve angle adjustment, so the multi-branch manipulato...

AI Technical Summary

Problems solved by technology

[0003] Existing mining detection manipulators mostly use the multi-joint folding method. However, the expansion and contraction of the multi-joint manipulator requires a certain three-dimensional space requirement. In addition, the mine environment is complex, and it is difficult for the robotic arm to extend to a sufficient length for detection in narrow spaces or high positions. The long mechanical arm is difficult to adjust and transfer under the mine, so the detection depth of the mining robot is relatively shallow, which leads to a small detection range, insufficient detection, insufficient data collection, and incomplete detection of potential dangers underground.
