Two-piece all-hydraulic tunnel drilling machine

Abstract

The invention discloses a two-piece all-hydraulic tunnel drilling machine comprising three parts, i.e. a power precession device, a hydraulic power unit and a console, wherein the power precession device and the hydraulic power unit are independently arranged in a two-piece mode, and the console is independently arranged or is arranged on the power precession device or the hydraulic power unit; the three parts are connected through pipelines; under the control of the control valve of the console, the hydraulic oil of the hydraulic power unit acts on the hydraulic motor of the power precession device through the pipeline to ensure that the power head of the power precession device not only can rotate but also can feed and move front and back. The three parts of the drilling machine of the invention are independently arranged and respectively installed; when construction is carried out in a tunnel, the power precession device only needs to be installed on a handling frame, and the hydraulic power unit, the console and the like are installed on the ground surface of the tunnel, thus the tunnel drilling machine is convenient to use; and when the drilling machine works, smaller tunnel space is occupied to ensure normal operation of construction. The invention obviously lowers the manufacturing cost, the use cost and the maintenance cost of the drilling machine and has higher economical efficiency.

Description

technical field [0001] The invention relates to a drilling rig for drilling holes in tunnels (tunnels), in particular to a split-type full hydraulic tunnel drilling machine which is easy to carry, move, install and use, and is suitable for drilling holes in tunnels. Background technique [0002] In the construction of consolidation grouting and curtain grouting in the construction corridor of the hydropower station, it is necessary to drill several holes with a certain diameter and depth on the circumference of 0°-360° in multiple cross-sections of the corridor; In the construction of railway tunnels, in many fields such as coal mine tunnel construction and geological disaster management, it is necessary to drill holes in multiple directions and directions in the tunnel. Existing domestic and imported hydraulic or mechanical tunnel drilling rigs generally have the disadvantages of large size, high price, high operating cost, and inconvenient use; Drilling rigs are large in ...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims at the disadvantages of large size, high price, high operating cost, inconvenient use, and not suitable for drilling construction in tunnels with relatively narrow space, etc., which are commonly found in existing tunnel drilling rigs, and provides a fully split-type design. The hydraulic tunnel drilling rig is more convenient to relocate, move, install and use, and the price is lower and the cost of use is low.
