[0030] The process method of a circulating mold hanging device provided by the present invention is as follows: In the first step, after the equipment of the tunnel-retaining working face is installed, five sets of support shaping mechanisms (each set includes two sets of left and right support shaping mechanisms 3) are installed and placed continuously using the circulating mold hanging device according to the support length of the rock-blocking support, which are used for the support shaping of the five mold bags. After completion, the circulating mold hanging device returns to both sides of the last mold bag and completes the grouting solidification.

[0031] In the second step, after the five mold bags have solidified and before the working face begins to be mined, the supporting shaping mechanism 3 on both sides of the last mold bag is grabbed and retracted by the circulating mold hanging device, and moved forward to the front mold bag. The first four mold bags are still in the supporting shaping state.

[0032] In the third step, the working face starts to be mined, the rock retaining support and the circulating mold hanging device move forward with the working face, the circulating mold hanging device reaches the sixth mold bag installation position and completes the mold hanging operation.

[0033] In the fourth step, after the sixth mold is installed and the unit support is in place, the circulating mold hanging device quickly withdraws to the second mold bag, grabs the original support shaping mechanism 3 and moves forward to the sixth mold bag, preparing to move forward to the seventh mold bag position for mold hanging as the working face is mined.

[0034] Step 5: The above steps are cycled according to the relevant time nodes such as actual mining, mold hanging, pouring, and solidification of the working face, and the rear support shaping mechanism 3 is alternately moved forward for the hanging and shaping of the next mold bag.

[0035] The circulating mold hanging method of a circulating mold hanging device provided by the present invention is specifically as follows: Before the circulating mold hanging device is used for mold hanging, firstly, two sets of supporting shaping mechanisms 3 are placed on two rear bases 12, and the lower ends of the four single pillars 301 of the supporting shaping mechanisms 3 are supported by the rear bases 12. The hooking claws 207 of the left and right sets of lifting and grabbing devices on the front side of the circulating mold hanging device are located between the first single pillar 301 and the second single pillar 301, and the hooking claws 207 of the left and right sets of lifting and grabbing devices on the rear side are located between the third single pillar 301 and the fourth single pillar 301. At this time, the lifting cylinder 202 is in a semi-extended state, and the lifting frame 201 is in a middle height position. At the same time, the telescopic cylinder 204 inside the lifting and grasping device is in a semi-extended state, so that the T-block 206 extends to the outside of the guide rail 208, and the upper fixed plate 302 inside the supporting shaping mechanism 3 is located in the slots of the two upper front and rear hooking claws 207, and the lower fixed plate 302 inside the supporting shaping mechanism 3 is located in the slots of the two lower front and rear hooking claws 207. The left and right groups of supporting shaping mechanisms 3 are limited in the left and right directions by the mutual engagement between the hooking claws 207 and the fixed plate 302.

[0036] When the circulating mold hanging device needs to perform the mold hanging operation, first control the device as a whole to move forward, control the front side columns 8 on the left and right sides to shrink, and the rear side columns 11 on the left and right sides to extend. At this time, the rear side beams 10 on the left and right sides are in close contact with the top of the tunnel, and the front side beams 7 on the left and right sides are separated from the top of the tunnel. Then control the push cylinders 6 on the left and right sides to extend, and the push cylinders 6 drive the front side anchoring supports 4 on the left and right sides to move forward as a whole. Then control the front side columns 8 on the left and right sides to extend, and the rear side columns 11 on the left and right sides to shrink. At this time, the rear side beams 10 on the left and right sides are separated from the top of the tunnel, and the front side beams 7 on the left and right sides are in close contact with the top of the tunnel. Then control the push cylinders 6 on the left and right sides to shrink, and the push cylinders 6 drive the rear side anchoring supports 5 on the left and right sides to move forward as a whole, and the rear side anchoring supports 5 on the left and right sides drive the upper lifting and grasping mechanism 2 and the support shaping mechanism 3 to move forward as a whole. Then, all the lifting cylinders 202 are controlled to continue to extend, all the lifting seats continue to rise, the lifting seats drive the hooking claws 207 to continue to rise, and the hooking claws 207 on the left and right sides drive the support shaping mechanisms 3 on the left and right sides to continue to rise, so that the lower ends of the four single pillars 301 of the support shaping mechanism 3 are separated from the upper end surface of the rear base 12. Next, all the telescopic cylinders 204 are controlled to continue to extend, and the telescopic cylinders 204 drive the T-block 206 to slide toward the outside of the guide rail 208 through the swing link 205, and the hooking claws 207 on the T-block 206 drive the support shaping mechanism 3 to move outward as a whole, until the support shaping mechanisms 3 on the left and right sides are pushed out to the top of the preset support position, at which time the lower ends of the single pillars 301 move out to the outside above the rear base 12. Then, the lifting cylinder 202 begins to contract, the lifting seat begins to descend, the lifting seat drives the hook claw 207 to descend, and the hook claws 207 on the left and right sides drive the support shaping mechanisms 3 on the left and right sides to descend synchronously until the lower end of the single pillar 301 contacts the tunnel floor, and the single pillar 301 stops descending, while the lifting cylinder 202 continues to contract, and the lifting seat drives the hook claw 207 to continue to descend, so that the slot of the hook claw 207 is separated from the fixed plate 302 of the support shaping mechanism 3, and then the support shaping mechanisms 3 on the left and right sides are placed on the tunnel floor. Then, the telescopic cylinder 204 is controlled to contract, so that the T-block 206 drives the hook claw 207 to slide toward the inner side of the guide rail 208, and the piston rods of all the single pillars 301 are controlled to extend at the same time, so that the steel bars on both sides of the mold bag are located in the slots of the piston rod heads of the single pillars 301, and as the piston rods of the single pillars 301 rise, they are connected to the top and fixed, and then grouting solidification and shaping are started.

[0037] When the circulating mold hanging device needs to retract the supporting shaping mechanism 3 to perform the circulating mold hanging operation, the control device is first moved to the position of the supporting shaping mechanism 3, and then all the single pillars 301 are controlled to retract the piston rods, and the telescopic cylinder 204 is controlled to extend, and the T-block 206 drives the hook claw 207 to slide toward the outside of the guide rail 208 until the hook claw 207 slides to the bottom of the fixed plate 302. Then the lifting cylinder 202 is controlled to extend, driving the lifting seat to rise as a whole, the lifting seat drives the T-block 206 to rise, and the T-block 206 drives the hook claw 207 to rise, so that the card slot of the hook claw 207 is engaged with the fixed plate 302. As the lifting cylinder 202 continues to extend, the hook claw 207 drives the fixed plate 302 to rise synchronously, so that the supporting shaping mechanisms 3 on the left and right sides rise synchronously, so that the single pillars 301 of the supporting shaping mechanism 3 are separated from the bottom plate of the roadway. Next, the telescopic oil cylinder 204 is controlled to extend and retract, driving the T-block 206 to slide toward the inner side of the guide rail 208, and the hooking claw 207 on the T-block 206 also drives the support shaping mechanism 3 to slide toward the direction of the lifting and grasping mechanism 2, until the single pillar 301 of the support shaping mechanism 3 moves to the top of the rear base 12. Finally, the lifting oil cylinder 202 is retracted, driving the lifting seat to descend, and the lifting seat drives the T-block 206 to descend, and the hooking claw 207 on the T-block 206 drives the support shaping mechanism 3 to descend together, until the lower end of the single pillar 301 of the support shaping mechanism 3 contacts the upper end surface of the rear base 12, so that the support shaping mechanisms 3 on the left and right sides return to the rear base 12 on both sides.
