Specifically, as shown in fig. 1 and 2, the anchor net laying device 10 can be used in combination with an anchor net trolley 40, which together form an anchor net laying apparatus, wherein the anchor net trolley 40 is used for anchoring an anchor net laid on a roadway roof via a tail anchor net laying mechanism 200 of the anchor net laying device 10 to the roof.
When the coal cutter or the excavator and the like finish corresponding operations on the tail area of the advance support, the advance support needs to carry the top circulation anchor net ring 30 and the tail anchor net roll 20 to move forwards, the anchor net advance support equipment correspondingly enters a laying stage, in the laying stage, the lifting support frame 310 of the main support assembly 400 descends for a first preset distance, the auxiliary support assembly 500 is still supported between the bottom plate and the top plate of the roadway, the forward driving piece 600 drives the main support assembly 400 to move forwards for a second preset distance, and in the process of descending and moving the main support assembly 400 forwards, the anchor net tensioning adjustment assembly 110 adjusts the tensioning degree of the top circulation anchor net ring 30. Here, in the forward stepping process of the main support assembly 400, since the top beams 320 of the main support assembly 400, the top beams 320 of the auxiliary support assembly 500 and the anchor net tension adjustment assembly 110 of the top circulation anchor net laying mechanism 100 together tension the top circulation anchor net ring 30, the circumference of the support formed by the top beams 320 of the main support assembly 400, the top beams 320 of the auxiliary support assembly 500 and the anchor net tension adjustment assembly 110 is changed in the process of the main support assembly 400 driving the top beams 320 to descend and move forward, and the anchor net tension adjustment assembly 110 can adaptively adjust the total circumference of the top circulation anchor net ring 30 according to the movement of the main support assembly 400, so that the top circulation anchor net ring 30 is maintained in a proper tension state.
Subsequently, the lifting support frames 310 of the main support assembly 400 are raised by a first preset distance so that the top beams 320 of the main support assembly 400 return to the original supporting height, and the top beams 320 again support the anchor net of the top circulating anchor net roll at the top area thereof at the roadway roof; wherein, in the process of ascending the main support assembly 400, the support circumference formed by the top beam 320 of the main support assembly 400, the top beam 320 of the auxiliary support assembly 500 and the anchor net tensioning adjustment assembly 110 is changed, and the anchor net tensioning adjustment assembly 110 correspondingly adjusts the tensioning degree of the top circulation anchor net ring 30, so that the top circulation anchor net ring 30 is kept in a proper tensioning state; thereby completing the forward stepping of the main support assembly 400.
The main support assembly 400 is supported between the bottom plate and the top plate of the roadway after forward stepping is completed, the lifting support frame 310 of the auxiliary support assembly 500 descends by a third preset distance, and the forward driving member 600 drives the auxiliary support assembly 500 to move forward by the second preset distance; similarly, when the circumference of the support formed by the top beam 320 of the auxiliary support assembly 500, the top beam 320 of the main support assembly 400, and the anchor net tension adjusting assembly 110 is changed during the process of the auxiliary support assembly 500 driving the top beam 320 to descend and move forward, the anchor net tension adjusting assembly 110 adaptively adjusts the tension of the top circulation anchor net ring 30 during the process of the auxiliary support assembly 500 descending and moving forward, so that the top circulation anchor net ring 30 is kept in a proper tension state. Meanwhile, as the auxiliary supporting component 500 can drive the tail anchor net laying mechanism 200 to synchronously descend in the descending process, the tail guide net driving component 230 drives the tail guide net component 240 to ascend in the descending process of the auxiliary supporting component 500, so that the tail guide net component 240 is kept at the initial supporting height, and the anchor net which is correspondingly supported and bypassed by the tail anchor net roll 20 keeps the top plate of the supporting roadway, so that the supporting stability and the supporting safety of the anchor net to the tail area are ensured; in the process of forward movement of the auxiliary supporting assembly 500, the tail screen guiding assembly 240 moves forward synchronously, and as the anchor screen laid on the top of the roadway by the tail anchor screen roll 20 is anchored to the top plate of the roadway by the anchor rod trolley 40, the anchor screen of the tail anchor screen roll 20 is pulled by the tail screen guiding assembly 240 to release the anchor screen outwards and be laid on the top plate of the roadway, the anchor screen released by the tail anchor screen roll 20 backwards lays a second preset distance area forward of the anchor screen laying device 10, and the anchor rod trolley 40 anchors the newly laid anchor screen accordingly.
