Problems solved by technology

[0002] Most of the current coal mine roadway excavation equipment and anchoring equipment are operated independently. Even if there is a certain degree of combination, due to the inevitable contradiction between the space position requirements between the excavation and anchoring, it is impossible to maximize their respective functions. The best performance, its disadvantages are: 1. After a certain progress in the excavation, the roadheader must withdraw to let the bolter enter the anchoring operation. After the anchoring operation is completed, the roadheader can enter the next round of excavation, or The roadheader must stop after digging for a certain distance, and continue to drive forward after the anchoring operation is completed. This operation method seriously affects the tunneling efficiency; Entering the anchorage operation, resulting in the lengthening of the empty head distance, especial

Embodiment 1

[0024] Embodiment one: see Figure 1-Figure 7 Double circular cutterhead coal roadheader. The roadheader includes a double-circular cutter head tunneling mechanism, a coal and rock conveying device, an anchoring mechanism, a traveling mechanism, etc.

[0025] Wherein, the double-circular cutter head tunneling mechanism includes two annular sub-beams 14 (cylindrical) horizontally arranged inside the machine head, see Figure 4 cross-sectional schematic diagram. The outer sides of the two annular sub-beams 14 are brackets, and four main drive motors 3 (or more) are fixed on the brackets outside each annular sub-beam 14, and the outermost side of the brackets is a shield 2, which is approximately rectangular structure.

[0026] The front ends of two annular sub-beams 14 are respectively equipped with a circular cutterhead 1, see image 3 , a certain number of hobs are arranged on each circular cutter head 1, and corresponding specifications and quantities of knives can be arr...

Embodiment 2

[0031] Embodiment two: see figure 1 , figure 2 , Figure 6 and Figure 7 , many parts and components of this embodiment have the same number as that of Embodiment 1, and represent the same meaning, so they will not be repeated here. In order to achieve the purpose that the head can be adjusted up and down, in this embodiment, in Figure 6 Torque cylinders 16 are set on the stays 8 in the center, that is, approximately vertical torque cylinders 16 are installed between the two sides of the support body 18 and the stays 8 on both sides respectively, and one end of the torque cylinders is arranged on the stays 8 . One end of the torque cylinder 16 is arranged on the shoe, the shoe cylinder 16 is responsible for the left and right adjustment of the machine head, and the torque cylinder 16 is responsible for the up and down adjustment of the machine head. The cutterhead is realized.

Abstract

The invention discloses a coal roadway tunneling machine with double round cutter heads. The coal roadway tunneling machine comprises round cutter heads, a shield, a scraper conveyer, an annular girder, an anchor rod drilling machine, a girder beam, supporting shoes, a rear support and a belt conveyor, wherein the cutter heads of a host machine employs double round cutter heads which are arranged in a staggered way; the length between two crossing points where two rounds are overlapped is the height of the section of a rectangular roadway. An operator carries out anchoring operation under the shield so as to realize the safe production. A thrust cylinder provides a reacting force through the supporting shoes which are tightly supported against the side wall; a thrusting force acts on the cutter heads through the crossbeam of the host machine cutter; the supporting shoes are matched with rear support, thereby realizing the continuous tunneling of the whole coal roadway tunneling machine. Cut coals and rocks are conveyed out of a feed bin through the scraper conveying machine. The coal roadway tunneling machine with double round cutter heads has the advantages of fast tunneling speed, low abrasion of cutters, integrated construction of tunneling and anchoring, etc. and the cost of unit tunneling number is greatly reduced. In addition, tunneling and anchoring are carried out simultaneously, therefore, the continuous operation is realized, and the labor productivity is improved.

Description

technical field [0001] The invention relates to a mechanical equipment for tunneling and anchoring with a rectangular section, in particular to a mechanical equipment for synchronous operation of tunneling and anchoring and integrated excavation and anchoring, that is, a double-circular cutter head coal roadheader. Background technique [0002] Most of the current coal mine roadway excavation equipment and anchoring equipment are operated independently. Even if there is a certain degree of combination, due to the inevitable contradiction between the space position requirements between the excavation and anchoring, it is impossible to maximize their respective functions. The best performance, its disadvantages are: 1. After a certain progress in the excavation, the roadheader must withdraw to let the bolter enter the anchoring operation. After the anchoring operation is completed, the roadheader can enter the next round of excavation, or The roadheader must stop after digging...
