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

The invention discloses a cutterhead device for large-diameter full-section impact crushing of hard rock. A mechanical transmission portion comprises a shell ring, three driving motors are mounted on the inner side of the shell ring by each other 120 degrees, a main driving motor is meshed with a transmission gear ring through a gear on an output shaft, the transmission gear ring is fixed in rear of a transmission barrel which is mounted in the shell ring and coaxial with the same, and a rotation big cutterhead is fixed in front of the transmission barrel; 1-3 gear holes are formed in the rotation big cutterhead, a planetary gear disc is mounted in the gear holes, three planetary-gear inner gears at 120-degree internals are fixed in the planetary gear disc and meshed with the gear holes, and 1-3 deslagging ports are arranged on the rotation big cutterhead. The cutterhead device has the advantages that energy consumption in repeated crushing is reduced; motion tracks of each impact hammer rock-crushing drill bit on a full section are continuous, dense, regular and stable; power load is lowered, and comprehensive efficiency and benefit of full-section impact crushing of the hard rock can be brought into full play.

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...
