Embodiment 1

[0022] Example 1, such as figure 1 As shown in the figure, a new type of rapid tunneling machine for coal roadway includes an adjustable shield body 1 and a rear support shield 2. The adjustable shield body 1 is connected with the rear support shield 2 through four propulsion cylinders 3, and the four propulsion cylinders stretch to realize the whole Step change and direction adjustment of machine equipment. The adjustable shield body 1 is provided with a cutting device 4 and an advanced drilling machine 5. The cutting device 4 swings up and down through the power provided by the hydraulic system to realize excavation of a rectangular section. The advanced drilling rig 5 performs advanced geological exploration operations through hydraulic control. The lower part of the adjustable shield body 1 is provided with a shoveling device 6, which collects the coal or rock excavated by the cutting device. A top bolter system 7 is arranged between the adjustable shield body 1 and the ...

Embodiment 2

[0023] Example 2, such as Figure 2-6 As shown, a new coal roadway rapid tunneling machine, the adjustable shield body 1 includes a top shield 1-1, a side shield 1-2 and a bottom shield 1-3, and the side shield 1-2 is symmetrically arranged on On both sides of the bottom shield 1-3, the lower part of the side shield 1-2 is hinged to the bottom shield 1-3, and the inner wall of the side shield 1-2 is provided with a lateral oil cylinder 1-4, and the lateral oil cylinder 1- One end of 4 is connected to the side shield 1-2, and the other end is connected to the bottom shield 1-3. Through the expansion and contraction of the lateral oil cylinder, the side shield rotates around the hinge point to realize the tight support of the side shield to the roadway. protect. The inner wall of the top shield 1-1 is provided with a top-facing oil cylinder 1-5, one end of the top-facing oil cylinder 1-5 is connected with the top shield 1-1, and the other end of the top-facing oil cylinder 1-5 ...

Embodiment 3

[0027] Embodiment 3, a new type of rapid roadheader for coal roadway, the scraper device 6 includes a bucket 6-1, and the lower surface of the bucket 6-1 is provided with a slag removing tooth plate 6-2, which is used to remove coal and soil sent to the bucket, the rear of the bucket 6-1 is provided with a slag delivery channel 6-3, the slag delivery channel 6-3 is connected with the slag conveying system 10, and the slag conveying system 10 adopts a scraper conveyor. For the transportation of coal soil or rock soil. Two groups of brace shoes 2-1 are arranged symmetrically inside the rear support shield 2, and the two groups of brace shoes 2-1 are connected through the brace cylinder 2-2, and the brace cylinder is set horizontally, and the brace shoes can realize left and right expansion and contraction through the control of the cylinder . The stretching out of the tensioning cylinder realizes that the strut shoe is tightened on the wall of the cave, which can provide the su...

Abstract

The invention discloses a novel coal roadway rapid excavator which solves the problem that a coal roadway excavating device is low in safety coefficient and low in work efficiency in the prior art. The novel coal roadway rapid excavator comprises an adjustable shield body and a rear supporting shield. The adjustable shield body is connected with the rear supporting shield through a propelling oilcylinder. A cutoff device and an advanced drilling machine are arranged in the adjustable shield body. A shoveling device is arranged at the lower portion of the adjustable shield body. A top anchor rod drilling machine system is arranged between the adjustable shield body and the rear supporting shield. A side anchor rod drilling machine system, a dust removal system and a slag stone delivery system are arranged on the rear support shield. The slag stone delivery system is connected with the shoveling device. The novel coal roadway rapid excavator has the advantages of being high in geological adaptability, high in excavating efficiency, high in mechanical degree, safe in operation and the like and has high popularization value.

Description

technical field [0001] The invention relates to the technical field of coal mine roadway construction, in particular to a novel coal roadway fast heading machine. Background technique [0002] The roadway excavation operation is the prerequisite for all other mining operations in coal mine production. With the substantial improvement of the working efficiency of the mining face, the contradiction that the roadway excavation speed cannot keep up with the mining demand has become more and more prominent in many mining areas. Safe, rapid and efficient roadway excavation and support technology is a necessary condition to ensure high production and high efficiency in coal mines. At present, there are three main methods for the mechanized rapid excavation of coal mine underground roadways: the first is the traditional single-lane excavation, and the main equipment on the working face is a roadheader and bolter; the second is double-lane excavation, which uses continuous coal minin...
