Integrative machine for transshipping and supporting gangues in tunnel of coal mine

Abstract

The invention provides an integrative machine for transshipping and supporting gangues in a tunnel of a coal mine, and relates to construction equipment for the blasting driving tunnel of the coal mine, so as to emphatically optimize the implementation of a gangue loading and supporting process. During tunnel driving construction, rock loading, transportation and gangue discharge are working procedures consuming most of the cycle time in the driving work. The achievement of rapid and efficient driving of the tunnel encounters prominently-expressed problems that the gangues accumulate on a driving working face, cannot be timely discharged, and are difficult to temporarily support and fix. In order to solve the problems, the invention provides the integrative machine for transshipping and supporting the gangues in the tunnel of the coal mine, which can utilize blasting energy to timely transship the gangues and simultaneously provide a platform for the supporting operation. The integrative machine is designed through fully analyzing the characteristics of driving and blasting operation of the coal mine, is formed by combining and processing an aluminum bronze plate with excellent heat dissipating performance, a hydraulic oil cylinder, and the like, has the advantages that a hydraulic system is adopted to provide power for the whole system and the power is output steadily, and can be applied to relatively complex geological environments.

Description

technical field [0001] The invention relates to construction equipment for coal mine roadway excavation, in particular to the process of loading gangue and roadway support for blasting the roadway. Background technique [0002] Under the objective situation that coal mining mechanization technology is becoming more and more mature, while the tunneling process is relatively complicated and the degree of mechanization is still low, tunneling workers have high labor intensity, low labor efficiency, low income level, and high risk factor. In the end, the tunneling labor is tense and inefficient, and coal mining is faster than tunneling, taking over the passive situation of tension. Roadway excavation is a multi-process alternating process, mainly composed of three major processes: rock breaking, loading and supporting. At present, rock breaking methods are generally divided into manual excavation, blasting, machinery, etc.; shipment mainly uses rake machines, fully-mechanized e...

AI Technical Summary

Problems solved by technology

The rapid development of science and technology has led to the emergence of various new roadway excavation equipment and technologies, and has steadily increased the excavation speed. However, the existing excavation equipment has poor adaptability, lack of performance, high failure rate, high maintenance costs, and limited application of automation. The driving speed of coal mine roadway production has formed a bad influence

In order to realize the rapid and efficient excavation of the roadway, the outstanding performance is that the accumulation of gangue on the excavation face is serious, and the work of gangue discharge and gun inspection cannot be carried out in time; It is more difficult for personnel to stand on ladders or false platforms when the support operation is carried out after exceeding 2.2 meters

Gangue discharge and support operations cannot be carried out in parallel, and large-section roadway support is difficult, which seriously restricts the update and development of mine mining equipment and seriously restricts the construction of safe and efficient mines
