Embodiment 1

[0023] Embodiment one: in figure 1 , figure 2 , image 3 and Figure 4 Among them, the large-diameter and full-section cutter head device for impacting and crushing hard rock includes two parts: a mechanical transmission and a drilling tool. The mechanical transmission part includes an outer shell ring 1, and three main drives are installed on the inner side of the outer shell ring 1 at 120 degrees to each other. Motor 2, the main drive motor 2 meshes with the transmission ring gear 3 through the gear on the output shaft, the transmission ring gear 3 is fixed behind the transmission cylinder 4, and the transmission cylinder 4 is installed in the outer shell ring 1, which Shaft, drive cylinder 4 fronts are fixed with revolution big cutterhead 5. There are three gear holes 6 that form 120 degrees each other on the large revolving cutterhead 5, and a center hole 7 is also arranged in the middle of the large revolving cutterhead 5. Planetary gear discs 8 are installed in the...

Abstract

A cutterhead device with a large diameter and full section impacting and crushing hard rock. The mechanical transmission part includes an outer shell ring, and three main drive motors are installed on the inner side of the outer shell ring at 120 degrees to each other; the main drive motor passes through the gear on the output shaft and the transmission gear. The transmission ring gear is fixed behind the transmission cylinder, the transmission cylinder is installed in the outer shell ring, coaxial with the outer shell ring, and the front of the transmission cylinder is fixed with a large revolving cutterhead; there are 1‑3 gears on the large revolving cutterhead A planetary gear disc is installed in the gear hole, and three internal planetary gears at 120 degrees to each other are fixed inside the planetary gear disc. Slag outlet. The advantages of the present invention are: 1. Reduce repeated crushing energy consumption; 2. The trajectory of each group of impact hammer rock-breaking drill bits on the full section is continuous, dense, regular and stable; Comprehensive efficiency and effectiveness of section impact crushing performance in hard rock.

Description

technical field [0001] The invention relates to an underground large-diameter excavation engineering machinery device, that is, an underground excavation engineering machinery cutterhead assembly with a large diameter and full section impacting and crushing hard rock. Background technique [0002] In the construction of roads, railways, subways and mines, large-diameter tunnels need to be excavated underground. In the past two decades, the tunneling (shield tunneling) machine widely used in tunnel engineering has developed rapidly. From the original, it was only suitable for the construction of loose (soft) granular geological layers, and now it is still adapting to full-section hard rock geology (such as mines) Roadway, etc.) and the direction of super large diameter. But at present, the roadheader manufactured for full-section hard rock geology still stays in the method of "breaking the rock with the hob". Although the "rock breaking with hob" has been successfully appli...
