A rock drilling jib structure with one arm and two drills

Abstract

The invention discloses a one-arm two-drill rock drilling boom structure. The structure comprises a long carriage (4) connected with a drill boom (9) by using a connecting mechanism, wherein a gadder (3) capable of moving and horizontally and rotationally swinging is arranged on the long carriage; a short carriage (11) is arranged on the connecting mechanism and is connected with an anchor drilling machine (22); the connecting mechanism comprises a back-and-forth swing mechanism (7) connected with the drill boom; a supporting seat (5) is arranged at one end of the back-and-forth swing mechanism; the long carriage is movably connected with the supporting seat by virtue of a connecting seat (6); a cantilever support (15) with adjustable height is arranged on one side of the supporting seat; a horizontal spiral swing mechanism (14) is arranged on the cantilever support; the short carriage comprises an upper chute (18) and a lower chute (19) which are in convex-concave sliding fit. The structure is a novel rock drilling boom with full drilling functions and wide operating range and can be widely applied to tire-type or crawler-type single-boom and double-boom even multi-boom drill jumbos or drilling and loading integrated machines.

Description

technical field [0001] The invention relates to the design of a rock drilling boom structure, in particular to an ordinary rock drilling boom and a bolt and anchor cable drilling boom, which is a combination of rock drilling blast hole drilling and bolt A new type of one-arm two-drill rock drilling jib structure with highly integrated anchor cable hole drilling functions. Background technique [0002] At present, in the construction of coal mines, non-coal mines, railway roads, water conservancy culverts and urban pipe galleries, whether it is single-arm, double-arm or multi-arm rock drilling jumbo (tyre type or crawler type), or single arm, double arm or Roadway rock drilling equipment such as dobby drilling machine, or rock bolter, etc., there is only one drilling device on a set of rock drilling booms, that is, only one kind of construction hole can be drilled, or only head-on blasting can be drilled. Holes or detection holes (generally use a rock drilling rig or a drill...

AI Technical Summary

Problems solved by technology

In this way, for a narrow roadway, two sets of equipment alternately move to the working surface for operation, which will affect the construction efficiency, directly affect the support quality, roadway forming speed, labor intensity, etc., and the number of workers is also large. In addition, the equipment in the roadway Parking is also a problem. During the construction process, alternate vehicles will bring potential safety hazards. However, using two sets of equipment requires a large investment in the construction unit, and the utilization rate of the equipment is not high.
