Example Embodiment

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like figure 1 shown, figure 1 The rock drilling apparatus 100 is schematically shown including a rock drilling arm assembly 1 , a yaw hydraulic cylinder 2 , a pitch hydraulic cylinder 3 and a rock drilling mechanism 4 .

[0025] In the embodiment of the present application, the rock drilling arm assembly 1 is a telescopic structure, which is driven by a hydraulic cylinder (not shown in the figure) to realize the elongation and shortening of the rock drilling arm assembly 1 .

[0026] The deflection hydraulic cylinder 2 is hinged with the deflection end 111 of the rock drilling arm assembly 1 to actuate the rock drilling arm assembly 1 to perform a deflection movement. With this structure, the rock drilling arm assembly 1 can be flexibly adjusted to deflect leftward or rightward relative to its geometric centerline, thereby expanding the working range of the rock...

Abstract

The invention relates to a rock drilling device for a drill jambo. The rock drill device comprises a rock drilling arm component, a deflection hydraulic cylinder, a pitch hydraulic cylinder and a rock drilling mechanism. The deflection hydraulic cylinder is hinged to a deflection end of the rock drilling arm component to drive the rock drilling arm component to deflect; the pitch hydraulic cylinder is hinged to the deflection end of the rock drilling arm component to drive the rock drilling arm component to pitch; the rock drilling mechanism is connected with a telescoping end of the rock drilling arm component. The rock drilling device for the drill jambo has the advantages of wide working range, high movability, flexibility in operation, high stability and high quake resistance.

Description

technical field [0001] The invention relates to the technical field of tunnel construction or roadway excavation, in particular to a rock drilling device for a rock drilling rig. Background technique [0002] Rock drilling rig, also known as drilling rig, is a kind of rock drilling equipment used for drilling and blasting construction in tunnels and underground works. Rock drilling rigs were introduced in the early 1980s and can move and support multiple rock drills for simultaneous drilling operations. [0003] The existing rock drilling rig is mainly composed of a rock drill, a drill arm (support, positioning and propulsion mechanism of the rock drill), a steel frame, a running mechanism and other necessary auxiliary equipment. When the drilling method is used to excavate the tunnel, favorable conditions are provided for the drilling rig. The combination of the drilling rig and the ballast equipment can speed up the construction speed, improve the labor productivity, and ...
