The operating arm also typically includes a bolt magazine 8 for storing and delivering bolts 7 to the grouting assembly 3, enabling unmanned installation of the bolts 7.

Wherein, propelling beam 1 is a section of thick bamboo, and its self length direction is first direction, and propelling beam 1 extends along first direction to have front end and rear end, the front end supports to lean on the cliff to realize relatively fixed between operation arm and the cliff, makes things convenient for drilling subassembly 22 drilling or slip casting subassembly 3 slip casting.

The first sliding plate 21 is used for supporting the fixed drilling assembly 22 and the grouting assembly 3, and is slidably mounted on the propulsion beam 1, and a sliding rail and a sliding track are generally arranged between the fixed drilling assembly 22 and the propulsion beam 1, and the first sliding plate 21 can slide along a first direction, and the first sliding plate 21 is divided into a front part 211 and a rear part 212 along the first direction, and a locking mechanism 23 is arranged between the two parts, and has:

in the combined state, the locking mechanism 23 is locked, and the two parts are relatively fixed and synchronously slide;

in the separated state, the lock mechanism 23 is unlocked, and the two parts are separated from each other, at least one of which is slidable.

The drilling assembly 22 is slidably mounted on the rear portion 212 in a second direction that is not co-directional with the first direction, and a first driving mechanism is disposed between the drilling assembly 22 and the rear portion 212 for driving the drilling assembly 22 to slide, and includes:

a first working position, in which the drilling assembly 22 is at the rear end of the feed beam 1 and its drill string axis is at the centre line position of the feed beam 1, and in which the locking mechanism 23 is locked and the front part 211 and the rear part 212 of the first slide plate 21 are engaged, in which the lower drilling assembly 22 can be slid in a first direction to drill a rock wall;

in the first standby position, the drilling assembly 22 returns the rear end of the push beam 1 along the first direction after drilling is completed, slides along the second direction, drives the drill rod 6 to synchronously shift, avoids a space for the grouting pipe 31 to work, and facilitates subsequent grouting operation.

Slip casting subassembly 3 is connected and is fixed in the front portion 211 of first slide 21, and slip casting subassembly 3 is provided with the second actuating mechanism who removes slip casting pipe 31, and slip casting pipe 31 relies on the second actuating mechanism to have:

the second working position, the drilling assembly 22 slides to the first standby position, the grouting pipe 31 moves close to the first sliding plate 21 until the axial lead of the grouting pipe is aligned with the anchor rod mounting hole, at the moment, the locking mechanism 23 releases the lock, the front part 211 and the rear part 212 of the first sliding plate 21 are in a separated state, the grouting pipe 31 can slide along the first direction, the anchor rod is conveyed into the drilling hole after the anchor rod is butted, grouting is carried out, and grouting can also be carried out by sliding along the first direction and aligning with the anchor rod mounting hole;

in the second standby position, the grouting pipe 31 is moved away from the first sliding plate 21 until a space for completing the drilling operation when the drilling assembly 22 is in the first working position is left. Realize slip casting pipe 31 and drilling subassembly 22 and work in turn, specifically, slip casting pipe 31 is in the second standby position, and drilling subassembly 22 is in first operating position, and both combine to slide to the front end in step and carry out the drilling operation, accomplish the back, withdraw to the rear end, and drilling subassembly 22 slides until being in first standby position along the second direction, and slip casting pipe 31 removes and is in the second operating position, and both separation carry out corresponding slip casting operation.

The switching of the positions of the drilling assembly 22 and the grouting assembly 3 is the operation flow of the operation arm, and the specific operation flow is as follows: the drilling subassembly 22 is in first operating position, supports to lean on the rock wall relatively fixed back when the operating arm, and the drilling subassembly 22 slides along the first direction and moves ahead, carries out the drilling operation, and after the drilling operation was accomplished, the drilling subassembly 22 slides along the first direction and retreats to the rear end of propulsion beam 1, simultaneously, forms an stock mounting hole on the rock wall. Subsequently, drilling subassembly 22 slides along the second direction and moves to first standby position, and slip casting pipe 31 of slip casting subassembly 3 moves to the second operating position, butt joint stock 7, slides along the first direction and moves ahead, send into the stock mounting hole with stock 7, carries the thick liquid afterwards, and after the slip casting operation was accomplished, slip casting subassembly 3 retreats along the first direction to leaning on rear portion 212, moves slip casting pipe 31 to second standby position, and drilling subassembly 22 slides and moves to first operating position.
