A rock drilling device that can perform a variety of work methods

Abstract

The present invention provides a rock drilling device capable of performing various operation modes, which is configured such that the main components of the rock drilling device can perform various operations such as a head swing operation, a horizontal rotation operation, an omnidirectional swing operation, a sliding operation, and a rotating operation. , by adapting the entering direction of the rock-drilling blade body to any conditions of the rock-splitting rock and inserting the borehole quickly and accurately, a good rock-splitting operation can be performed. In the rock drilling device formed by combining the device body and the device outer body, the device body consists of a main cylinder body, a wedge body arranged on the extension of the piston rod of the main cylinder body, and an expandable body abutting on the outer side surface at the top end of the wedge body. It is composed of a pair of rock drilling blade bodies, the outer body of the device is composed of an outer body casing that is slidably loosely fitted with the device body on the outer periphery of the device body along the axial core direction, and the arm of the backhoe for work is prepared separately. The top end of the bracket is provided with a device mounting base plate, and a tunnel-shaped support body is protruded rotatably around the axis on the device mounting base plate. A way of working is possible.

Description

technical field [0001] The present invention relates to a rock drilling device capable of performing various operation modes, which can accurately and smoothly insert a rock drilling blade body into a rock hole by freely changing the posture of the rock drilling device at a rock splitting work site Adjustments make good splitting possible with reliable extended operation of the rock drill blade body. Background technique [0002] Up to now, at a rock splitting site, a drilling rig is used to drill a plurality of boreholes of a certain depth from the rock surface of the rock splitting target, and then a pair of rock drilling blade bodies at the tip of the rock drilling device are inserted into the plurality of drill holes along the above-mentioned rock splitting direction. Hole, the hydraulic cylinder is used to expand the rock drilling blade body in the hole through the wedge body to perform rock splitting in sequence. [0003] The rock-splitting operation of the above-ment...

AI Technical Summary

Problems solved by technology

[0005] Therefore, it is relatively difficult to insert a thin rod-shaped rock drilling blade body into a small-diameter drill hole only by swinging or horizontally rotating the boom, arm, and bucket of the backhoe.
