Narrow-body rotary four-arm jumbolter for coal mine

Abstract

The invention discloses a narrow-body rotary four-arm jumbolter for a coal mine. The four-arm jumbolter comprises a bottom platform, a walking mechanism, a power mechanism and a control mechanism, wherein the power mechanism and the control mechanism are arranged on the top surface of the bottom platform; the walking mechanism is arranged on the bottom surface of the bottom platform, a rotary mechanism is arranged between the walking mechanism and the bottom platform, and the control mechanism is connected with the power mechanism and the walking mechanism separately so as to control the powermechanism and the walking mechanism; and a sliding base is arranged on the bottom platform, a first executing mechanism and a second executing mechanism which have the same structure and are symmetrically arranged left and right are arranged at the two ends of the sliding base, and the first executing mechanism and the second executing mechanism are connected with the power mechanism separately so as to be controlled by the control mechanism to move towards / away from each other along the sliding base. The four-arm jumbolter is compact in structural design and high in operation efficiency, andthe safety of operators and the supporting safety performance are greatly improved.

Description

technical field [0001] The invention relates to the field of supporting drilling equipment for underground roadways in coal mines, in particular to a narrow-body rotary four-arm rock bolt drilling rig for coal mines. Background technique [0002] With the rapid development of my country's economy, the demand for energy, especially coal, is increasing, and the amount of domestic coal mining is also rising steadily. While coal production is increasing year by year, safety work in coal mines is becoming more and more important, and many primitive operating methods are facing challenges from advanced technologies. In some mining areas with medium-thick coal seams, due to the limited thickness of the coal seam, the height of the roadway is generally not high, mostly between 2-3.5 meters. Many large-scale anchoring equipment cannot enter at all, and the roadway roof can only be anchored manually. The operation is not only time-consuming and labor-intensive, but also has great pot...
