[0028] As Figures 1 - 13 shown, in this embodiment, the rapid construction method of the intelligent arch anchor trolley for controlling large rock mass deformation is as follows: S1: Control the first arch frame installation device 31 on the first manipulator 3 at the end of the first working arm 21 to grab the arch top arch frame section 7, lift and position it to the installation position, and control the second arch frame installation devices 61 on the second manipulators 6 at the ends of the two side second working arms 22 to grab the arch waist arch frame sections 8, lift and position them to the installation position. The construction workers in the arch cable feeding switching hanging basket 631 first perform auxiliary construction on the connecting bolts, mesh sheets, and connecting bars of the arch waist arch frame section 8, and then perform auxiliary construction on the connecting bolts, mesh sheets, and connecting bars of the arch top arch frame section 7.

[0029] Specifically: Prefabrication of the arch frame: Divide the arch frame for supporting the inner side wall of the mine tunnel into three sections, namely the arch top arch frame section 7 and the arch waist arch frame sections 8 on both sides of the arch top arch frame section 7; each arch section is prefabricated outside the mine cave. Transport the arch top arch frame section 7 and the arch waist arch frame sections 8, and use transportation equipment to transport them into the cave respectively and place them at the designated position on the heading face, with the outer chord side of the arch frame on the ground and the connecting flange facing up.

[0030] The power unit 4 provides power to drive the chassis 1 to travel to the heading face; the power unit 4 drives the legs of the chassis 1 to extend and support, so that the whole machine is level.

[0031] The power unit 4 drives the operation unit 2 to unfold, and the first manipulator 3 and the second manipulator 6 to the corresponding positions for grabbing the arch frame. The power unit 4 drives the first working arm slewing device 214 to rotate, so that the first arch frame installation device 31 of the first manipulator 3 rotates to the front. In addition, the power unit 4 drives the second working arm slewing device 224, so that the second arch frame installation device 61 of the second manipulator 6 rotates to the front.

[0032] The power unit 4 drives the arch frame installation slewing device 311 of the first manipulator 3, so that the arch frame grabbing device 314 of the first arch frame installation device 31 rotates to the lower side.

[0033] The power unit 4 drives the arch frame installation slewing device of the second manipulator 6, so that the arch frame grabbing device of the second arch frame installation device 61 rotates to the lower side.

[0034] The power unit 4 drives the first telescopic boom 211 of the first working arm 21, the first lifting cylinder 212, the first working arm slewing device 214, the first working arm leveling cylinder 215, and the clamping cylinder 3142 of the arch grabbing device 314, so that the first arch installing device 31 can effectively grab the arch top arch section 7.

[0035] The power unit 4 drives the first telescopic boom 211 of the first working arm 21, the first lifting cylinder 212, the first working arm slewing device 214, the first working arm leveling cylinder 215, the clamping cylinder 3142 of the arch grabbing device 314, and the arch installing slewing device, so that the first arch installing device 31 can lift, yaw, and slew, and move the arch top arch section 7 to the position to be installed.

[0036] The power unit 4 drives the second telescopic boom 221 of the second working arm 22, the second lifting cylinder 222, the second working arm slewing device 224, the second working arm leveling cylinder 225, the clamping cylinder of the arch grabbing device, and the arch installing slewing device, so that the second arch installing device 61 can lift, yaw, and slew, and move the arch waist arch section 8 to the position to be installed.

[0037] The auxiliary operator performs the construction operations of connecting bolts, mesh sheets, and connecting bars in the hanging basket of the hanging basket switching device 63 to preliminarily fix the arch top arch section 7 and the arch waist arch section 8; after the construction of the connecting bolts, mesh sheets, and connecting bars is completed, the power unit 4 drives the first horizontal slewing device 331 of the first manipulator 3 to move the rock drilling device 32 in front of the first manipulator 3.

[0038] S2: Switch the first manipulator 3 at the end of the first working arm 21 to the construction station of the locking foot bolt, control the rock drilling device 32 on the first manipulator 3 to perform the drilling construction of the locking foot bolt, and then manually assist in installing the locking foot bolt in the drilled hole.

When a single drill rod 328 reaches the deepest drilled hole, the drill rod clamping mechanism 323 is driven to clamp the drill rod, the rock drill recoils, the connection thread between the drill rod 328 and the tool shank connecting sleeve 327 is removed, and the rock drill retracts to the end.

[0041] After the construction of the locking-foot bolt holes is completed, the auxiliary operator drives the second working arm 22 in the hanging basket to the drilling position to assist in the installation and tensioning of the bolts.

[0042] S3: After the construction operations of the arch crown arch frame section 7 and the arch waist arch frame section 8 are completed, the first manipulator 3 and the second manipulator 6 are respectively switched to the cable anchor construction workstations. The cable anchor drilling construction is carried out through the rock drilling device 32 on the first manipulator 3, and the cable anchor installation operation is carried out through the cable feeding device 62 on the second manipulator 6.

[0043] Drive the first cable anchor clamping mechanism 622 of the second manipulator 6 under the cable feeding device. The operator assists to pass the cable anchor through the first cable anchor clamping mechanism 622 to the second cable anchor clamping mechanism 624, and drive the second cable anchor clamping mechanism 624 to clamp the cable anchor.

[0044] The power unit 4 drives the second working arm 22 and the second manipulator 6 to align the cable anchor pushing mechanism 623 with the cable anchor hole to be installed. Drive the cable anchor pushing mechanism 623 to drive the second cable anchor clamping mechanism 624 to move along the linear cable feeding track mechanism 621 to the front end of the cable feeding device 62. Drive the first cable anchor clamping mechanism 622 to clamp the cable anchor. Drive the second cable anchor clamping mechanism 624 to release the cable anchor.

Drive the first cable anchor clamping mechanism 622 to release the cable anchor. Drive the second cable anchor clamping mechanism 624 to clamp the cable anchor. Repeat the above steps to complete the pushing construction of this cable anchor.
