Automatic travelling system of mining intrinsically safe rail inspection robot

Abstract

The invention provides an automatic travelling system of a mining intrinsically safe rail inspection robot. The system comprises a bearing bridge, wherein a load bearing is fixedly installed on the bearing bridge, and is in contact with the inner side of the lower edge of a C-shaped guide rail, the two ends of the bearing bridge are connected to the two sides of a bearing support through connecting pieces, a speed sensor, a friction wheel, a driving motor and a brake device are arranged inside the bearing support, the driving motor drives the friction wheel to rotate through a gear, the driving motor, the speed sensor and the brake device are connected to a controller in a signal mode, the controller controls the brake device to move in the bearing support, so that the friction wheel is braked, the friction wheel and the load bearing are both in contact with the lower edge of the C-shaped guide rail, and the lever effect is formed between the load bearing and the friction wheel of thebearing bridge. The automatic travelling system of the mining intrinsically safe rail inspection robot is safe, reliable, simple to install, convenient to use, small in occupied space and low in cost.

Description

Technical field [0001] The invention belongs to the field of special robots, and particularly relates to an automatic walking system of an intrinsically safe track inspection robot for mines. Background technique [0002] A large number of workers are needed in coal production. Most of these workers' work is simple and repetitive. It is the general trend to replace people with machines. It is the dream of the coal industry to realize unmanned production underground. Conveyor belt transportation is a very critical equipment in coal mine production. As the annual output of coal mines is increasing, belt conveyors are required to run at high speeds, even reaching a speed of 7-8 meters per second. This high-speed operation requires high equipment , Once there is a problem with the bearing in the idler, the belt is not evenly stressed, it is easy to cause the belt to run off, the belt breaks, and cause a production shutdown accident. There are symptoms before the rollers have problem...

AI Technical Summary

Problems solved by technology

[0003] Coal mine production is a high-risk industry due to its harsh production environment and frequent gas outbursts. In this context, the industry now proposes that "machines replace people" has become the consensus of the entire industry. Inspection is an important part of safe production and requires a large number of workers The investigation of potential accidents in the roadway requires a high sense of responsibility. This kind of investigation requires the staff to walk a long distance, consumes a lot of physical strength, and needs to maintain concentration for a long time. It is inevitable that there will be missed judgments and misjudgments. Robots are in strong demand

[0004] In the past, self-inspection inspection systems mostly used I-beams as guide rails. The I-beam itself is heavy, and installation and debugging are more troublesome. In addition, the price is relatively expensive. Because the length of the belt along the groove is relatively long, more guide rails are required, and the cost of guide rails accounts for more. The cost ratio of this system is very high
