Novel quick digging and anchoring integrated machine for rectangular coal roadway

Abstract

The invention discloses a novel quick digging and anchoring integrated machine for a rectangular coal roadway, which comprises a heading machine, a temporary support system, an anchoring system, a conveying system and a dust removing system, and also comprises a support system, wherein a sealing device is arranged between the head of the heading machine and the front of the support system; the sealing device comprises a main body plate, a movable sealing plate and left and right movable sealing plates; support hydraulic cylinders are arranged on the main body plate and an upper movable sealing plate bracket; support hydraulic cylinders are arranged on the main body plate and left and right movable sealing plate brackets as well; meanwhile, an upper movable sealing plate, the left and right movable sealing plates are provided with flexible sealing belts; the front end of a dust removing pipeline of the dust removing system is installed on the main body plate of the sealing device; and the dust removing pipeline is communicated with the space in the front part of the sealing device. The novel quick digging and anchoring integrated machine for the rectangular coal roadway, provided by the invention, employs a novel telescopic cylinder to cut and mold the width of a roadway in one step, therefore, the high efficiency is achieved, and in addition, the damage to a base plate due to repeated displacement is avoided; through cooperation of adjusting oil cylinders with flexible sealing, a top plate and lateral walls are very adaptive, so that dust is prevented from rushing into a rear working space; and meanwhile, a working environment is improved.

Description

technical field [0001] The invention relates to underground bolt-digging construction equipment for mines, in particular to a novel integrated machine for rapid bolt-digging of rectangular coal roadways. Background technique [0002] At present, there are three main methods of mechanized rapid excavation of underground coal mine roadways: the first, traditional single-lane excavation, the main equipment of the working face is roadheader and bolter; the second, double-lane excavation, using continuous shearer for excavation, This type of excavation is equipped with an advanced bolter. While the continuous shearer is excavating the transport roadway, the bolter is performing bolting operations in the air return roadway. When the continuous shearer completes a tunneling cycle, Swaps places with a rock bolter. The third type is the single-tunnel excavation of the introduction of foreign integrated machine for digging and bolting. The disadvantages of the existing technology an...

AI Technical Summary

Problems solved by technology

The disadvantages of the existing technology and equipment are: the operation efficiency of the roadheader and bolter is low, which are mainly suitable for some small coal mines; the operation method of double-lane excavation realizes the separation of roadway excavation and support, and multiple bolts can be used at the same time. operation, support efficiency is greatly improved

However, in order to meet the requirements of machine mobilization and transportation, a connecting roadway is dug every 50m between the two roadways, which increases the cost of excavation, and the change of position between the continuous miner and the bolter also greatly affects the mining efficiency.
