Problems solved by technology

[0002] At present, tunnel construction often uses the cutting device of blasting excavation and roadheader. The former is highly dangerous and serious over and under excavation, resulting in a lot of waste of materials, slow construction progress, and is affected by factors such as local dangerous goods control.
The latter has high construction and operation costs (high price of accessories), too frequent equipment failure rate, high investment cost, serious over- and under-excavation of the tunnel floor during construction, multiple investments in tunnel excavation data changes, and hard rock formations that cannot be constructed defect
[0003] Existing cutting device, its cutting method often adopts center rotation to cooperate with the cutting mechanism of the front end similar to the roadheader, its cutting efficiency is low, easy to break down, maintenance is inconvenient, because the cutting efficiency of the existing cutting device is low, under-excavation situation Severe, and the propulsion of the roadheader is too rigid, causing the propulsion to be blocked, resulting in lower cutting efficiency and possible damage to the cutting device

Abstract

The invention belongs to the technical field of tunnel cutting devices, and discloses a rotary advancing and cutting device for a tunnel. The device comprises a rotary cutting head and an advancing device, wherein the rotary cutting head comprises a cutting device and a rotating device; the center of one side of the cutting device is provided with a power shaft mounting hole for being connected with the advancing device; and the position, deviating from the center, of one side of the cutting device is provided with a rotating mechanism for driving the cutting device to rotate on the whole. Therotary advancing and cutting device for the tunnel has the advantages of high cutting efficiency, simple structure, low cost, convenient maintenance and stable advancing.

Description

technical field [0001] The invention belongs to the technical field of tunnel cutting devices, in particular to a rotary propulsion cutting device for tunnels. Background technique [0002] At present, tunnel construction often uses blasting and boring machine cutting devices. The former is dangerous and serious over and under excavation, resulting in a lot of waste of materials, slow construction progress, and is affected by local dangerous goods control and other factors. The latter has high construction and operation costs (high price of accessories), too frequent equipment failure rate, high investment cost, serious over- and under-excavation of the tunnel floor during construction, multiple investments in tunnel excavation data changes, and hard rock formations that cannot be constructed defect. [0003] Existing cutting device, its cutting method often adopts center rotation to cooperate with the cutting mechanism of the front end similar to the roadheader, its cuttin...
