Girdling type tunneling equipment

Abstract

The invention discloses girdling type tunneling equipment which comprises a girdling main machine head, a propelling arm box, an angle adjusting device, a discharging box, a power box and a cooling box. The overall girdling main machine head is cylindrical, and an annular cutter head is arranged at the front end of the girdling main machine head; a plurality of cutters are arranged on the circular-ring-shaped cutter head and are uniformly distributed in the circumferential direction of the circular-ring-shaped cutter head; and the power box can drive the girdling main machine head to rotate so as to drive the cutter to achieve girdling tunneling. A first discharging channel is arranged in the middle of the girdling main machine head, and the discharging box is provided with a second discharging channel. In the tunneling direction, the discharging box is arranged behind the girdling main machine head, the first discharging channel is communicated with the second discharging channel, and core materials cut by the cutter can be discharged through the first discharging channel and the second discharging channel integrally or in a regular block shape. The working efficiency is improved by adopting an annular cutting tunneling mode, regular stones can be output online in real time, and the utilization rate of natural resources such as rocks is increased.

Description

technical field [0001] The invention belongs to the technical field of large-scale engineering equipment, and in particular relates to a ring-cut excavation equipment. Background technique [0002] At present, traditional shield machines such as mines, rock formations or tunnels rely on the cutter head on the front end of the machine shell and the hob cutter installed on the entire circular cross-section of the cutter head to complete the underground construction of the mine and rock formations. Cutting and drilling of the same length, so as to process the cylindrical tunnel required for the pre-laying of the pipeline. [0003] The cutting knives arranged on the cutter head of the traditional shield machine are mostly covered with the same full circle cross section. The tunnel wall surface cut and excavated by the cutting knives on the cutter head should be flat and without concave surface, so as to facilitate the laying of pipeline wall blocks in the later stage.

AI Technical Summary

Problems solved by technology

Due to the diversity of various rock formations in excavation and construction, the current method of full-circle drilling shield tunneling, the speed of cutting and excavating rock formations to complete the tunnel is generally low, and it also makes the complete machine cutter head, complete machine structure and each cutting tool The force is very large, resulting in a large demand power and a large energy loss

[0004] Moreover, the traditional shield machine breaks and discharges the rocks during the excavation process, and cannot make full use of the stones mined during the excavation process, which is likely to cause a waste of resources
