Embodiment Construction

[0022] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0023] Such as Figure 1-2 As shown, the present invention provides a pneumatic bolt and cable drilling machine, including a propulsion mechanism, a rotation mechanism and a manipulation control mechanism. The propulsion mechanism is a multi-stage air cylinder 2 used to advance and retract the rotation mechanism; the rotation mechanism consists of The pneumatic motor 10 compresses air to provide power, which is transmitted to the drill rod connecting shaft 5 after being decelerated by the gearbox 9 for drilling and / or the agitation of the anchor rod and the anchor cable; wherein, the rotating mechanism is also provided with a pretension The output shaft 7, the pre-tightening output shaft 7 is powered by a pneum...

Abstract

The invention relates to the technical field of roadway mining and discloses a pneumatic anchor rod and anchor cable drill loader. The pneumatic anchor rod and anchor cable drill loader comprises a feeding mechanism, a rotating mechanism and a steering control mechanism. The feeding mechanism is a multi-grade air cylinder and used for feeding and withdrawing the rotating mechanism. The rotating mechanism is powered by a pneumatic motor; rotation is transferred to a drilling rod connecting shaft after the rotating mechanism is decelerated by a gearbox; and the drilling rod connecting shaft is used for drilling and / or stirring of an initially-installed anchor rod and an initially-installed anchor cable. The rotating mechanism is further provided with a pre-tightening output shaft; and the pre-tightening output shaft is connected with the gearbox and used for pre-tightening an anchor rod nut. The pneumatic anchor rod and anchor cable drill loader integrates anchor rod drilling, installing and pre-tightening, saves labor force, has the effects of low labor intensity and high efficiency, improves safety, and reduces construction cost.

Description

Technical field [0001] The invention relates to the technical field of roadway mining, in particular to a pneumatic bolt and cable drilling machine. Background technique [0002] In order to greatly improve the safety of mine roadways and tunnels, the pre-tightening force of the anchor rod and cable is required to be larger and larger. The pre-tightening torque of the anchor rod is gradually increased from the traditional 100 NM to about 400 NM. The pre-tightening force of the anchor rod is correspondingly increased. It is increased from about 10KN to about 50KN-60KN, which greatly improves the support strength and rigidity of the roadway. However, the current pre-tightening torque of the traditional anchor bolt drilling rig is still maintained between 100-160NM, which cannot meet the pre-tightening requirements of high pre-tightening force anchor rods. It is difficult to pre-tighten the anchor rods with manual wrenches. At present, it is mainly dependent on adding one A torque ...
