High-adaptability digging and anchoring integrated machine with dual-mode anchor drilling system

Abstract

The invention provides a high-adaptability digging and anchoring integrated machine with a dual-mode anchor drilling system, and belongs to the technical field of underground coal mining equipment. The high-adaptability digging and anchoring integrated machine comprises a frame main body, a cutting system, a conveying system, a dust removing system, a multifunctional temporary supporting system, the dry-wet dual-mode anchor drilling system, an automatic lubricating system, a water-cooling spraying system, a hydraulic system and an electric control system, wherein a traveling mechanism adopts awide crawler design, so that the adaptability of the digging and anchoring integrated machine to a muddy bottom plate is improved; and the dry-wet dual-mode anchor drilling system has two functions of dry dust removal and wet dust removal, and real-time switching selection is carried out according to the geological conditions of the roadway bottom plate without replacing a drill box. By means ofthe high-adaptability digging and anchoring integrated machine, the problems of muddy of the bottom plate, poor stability of a top side wall and low tunneling efficiency in the rapid coal roadway tunneling under the complex geological conditions are solved; the integrated parallel operation of tunneling, anchor protection, transportation, dust removal and the like of a roadway tunneling working surface is realized; and the efficiency and safety of coal mining and transportation are improved.

Description

technical field [0001] The invention belongs to the technical field of underground mining equipment in coal mines, and specifically discloses a highly adaptable bolt-digger integrated machine with a dual-mode bolt-drill system. Background technique [0002] The excavation-anchor integrated excavation technology represents the highest technical level of excavation equipment at home and abroad, and leads the development direction of coal road excavation equipment. Anchor drilling machine is the core equipment of the drilling and anchoring integration technology. It is the product of the combination of continuous shearer and bolt drilling rig. Road excavation has obvious technical advantages. [0003] The research and development of the all-in-one anchor digging machine abroad began in the 1990s. At present, there are more than 400 anchor digging machines in use internationally. The representative models are ABM20 and MB670 of SANDVIK company and 12BM18 and 12ED25 of JOY compa...

AI Technical Summary

Problems solved by technology

The introduction and application of foreign integrated machine for mining and bolting has greatly improved the driving speed and safety level of coal roadways in my country, and achieved good economic benefits. However, there are still many problems in the application of imported integrated machines for mining and bolting: poor geological adaptability Diversified geological conditions in my country; high purchase and maintenance costs; difficult matching of main components and vulnerable parts, and long supply cycle of accessories; large size of the whole machine, it is not easy to separate and go into the well; inconsistent explosion-proof standards

At present, the roadheader is mainly used for construction. During the construction process, the excavation and support are separated, and the support mainly relies on a single bolter drilling machine. The labor intensity is high, the safety hazard is prominent, and the excavation speed is slow.

[0006] Through the patent search, it is found that domestic patents related to the integrated bolter digging machine (such as application number: 200710010159.1 Bolter digging machine with integrated bolter digging machine) are all similar models to the onboard bolter of the roadheader. Synchronous operation, the maximum number of bolts on board is 4 groups, the anchoring speed is limited, and the tunneling machine is used for tunneling, so the tunneling efficiency is low

However, no relevant patents related to the integrated bolter digging machine have been retrieved abroad.
