Therefore, two rows of flexible freight bag trains running in opposite directions can run in a staggered mode on the double track section 251, and the two rows of flexible freight bag trains are prevented from blocking each other.
In some embodiments, the stacking mechanism 3 further comprises a table disposed on the underside of the lifting link 31, the table being a movable platform.
Specifically, the workbench is driven by hydraulic pressure, so that the movable platform can move in the track, the moving direction of the workbench is perpendicular to the extending direction of the bearing platform 32, and the workbench is fixedly connected with the lifting connecting rod 31. Therefore, after one layer of bulk materials are stacked in the goaf, the workbench moves by the width of one bulk bag 21 in the direction away from the filled area, so that the stacking mechanism 3 can stack the next layer of bulk bags 21 in the goaf.
As shown in fig. 4-6, the present invention further includes a goaf bulk material return backfilling method of the goaf bulk material return backfilling system provided in accordance with any one of the above embodiments, comprising S01 loading bulk materials into a bulk bag 21 at a loading area using the loading mechanism 1; s02, transporting the bulk material containing flexible freight bag 21 to the goaf by using the transporting mechanism 2; s03, stacking the bulk material containing flexible freight bags 21 in the goaf by using the stacking mechanism 3; s04 returning the transport mechanism 2 from the gob to the loading zone; s05 repeats the above steps until the gob is back-filled at a single step.
Specifically, when the loading mechanism 1 is used to load bulk materials into the bulk bags 21 in the loading area, S01 loads each bulk bag 21 with the same amount of bulk materials, which is advantageous for making the volumes of the bulk bags 21 similar, so that the stacking work is stable when stacking the bulk bags 21; s02, when the bulk material containing bulk materials 21 are transported to the goaf by the transportation mechanism 2, the bulk material containing bags 21 are combined into a bulk material train, and the bulk material containing bags 21 are transported in a row, wherein the number of the bulk material containing bags 21 in the bulk material train can be the same as that of the bulk material containing bags 21 on each layer during stacking, so that the transportation efficiency is improved, the stacking time can be reduced, and the stacking efficiency is improved. S05, repeating the above steps until the goaf is filled with a single step, wherein the single step means that after the stacking mechanism 3 has fully stacked the previous layer of bulk bags 21, the stacking mechanism 3 moves a distance away from the stacked bulk bags 21, and the distance is a single step.
In some embodiments, S01 uses the loading mechanism 1 to load bulk material into the bulk bags 21 at the loading area, including: s11 loading the bulk material into individual bulk bags 21 using the loading mechanism 1; s12, hanging the flexible freight bag 21 on the self-discharging monorail hanging hook 22; s13 self-unloading monorail hanging hooks 22 are mutually combined into a container bag train; s14 uses the tractor 24 to pull the bulk bag train.
Specifically, in S12, the bulk bag 21 is mounted on the self-discharging monorail suspension hook 22, the upper end of the bulk bag 21 is provided with a suspension loop, and the bulk bag 21 is mounted on the corresponding self-discharging monorail suspension hook 22 through the suspension loop. S13 the self-discharging monorail suspension hooks 22 are mutually combined into a bulk bag train, and a plurality of self-discharging monorail suspension hooks 22 are mutually connected on the lifting rail 13 by the inter-hook connecting rod 23, thereby forming a bulk bag train. From this, use connecting rod 23 indirect connection self-discharging monorail crane hook 22 between the couple, improve the stability of connecting between the self-discharging monorail crane hook 22 on the one hand, on the other hand has increased the nimble degree of flexible bag train when along the track motion of buckling through the mode that increases the chain link. S14 the traction device 24 pulls the bulk bag train, and the traction device 24 moves the bulk bag train along the lifting track 13 from the loading zone to the gob.
In some embodiments, S03 using the stacking mechanism 3 to stack bulk bags 21 in the gob includes S31 lifting the carrier platform 32 in the stacking mechanism 3 after the bags 21 reach the discharge location; s32, after the bearing platform 32 is lifted to the proper position, the flexible freight bag 21 falls onto the bearing platform 32, and the self-discharging monorail crane hook 22 is opened; s33 the carrying platform 32 with the bulk bag 21 is raised or lowered into position; s34 after the carrier platform 32 has reached the proper position, the bag pushing assembly 33 stacks the bulk bags 21 in place; s35 push bag member 33 back and load-bearing platform 32 is lowered.
Specifically, S31 when the bulk bags 21 reach the discharge position, in which both ends of the train of bulk bags are aligned with both ends of the stack of bulk bags 21, i.e., the length of the train of bulk bags corresponds to the width of the stack of stacked bulk bags 21, the load-bearing platform 32 in the stacking mechanism 3 is raised. S32 when the carrying platform 32 is lifted to the proper position, the bulk bag 21 falls onto the carrying platform 32, and the self-discharging monorail suspension hook 22 is opened, wherein the lifting of the carrying platform 32 to the proper position means that the upper end of the carrying platform 32 contacts with the lower end of the bulk bag 21, and the bulk bag 21 is completely supported by the carrying platform 32, and at this time, the self-discharging monorail suspension hook 22 is not disconnected from the bulk bag 21. S33 the loading platform 32 with the bulk bag 21 being raised or lowered into position means that the upper edge of the loading platform 32 is at the same height as the upper edge of the bulk bag 21 when a portion of the bulk bag 21 has been deposited in the goaf. Thus, the bag pushing member 33 pushes the bulk bag 21 horizontally, and the bulk bag 21 does not roll or the like when sliding up from the loading platform 32 onto the stacked bulk bag 21. S34 after the carrying platform 32 has reached the proper position, the push bag unit 33 stacks the bulk bags 21 in the proper position, meaning that the side of the bulk bag 21 being pushed in by the push bag unit 33 that is remote from the push bag unit 33 is in contact with the side of the stacked bulk bag 21 and the position in the vertical direction of the bulk bag 21 being pushed in by the push bag unit 33 is substantially the same as the position of the underlying bulk bag 21.
In some embodiments, the monorail crane track outside the double-rail section 251 is traversed as the transport mechanism 2 moves from the loading area to the goaf area; the transport means 2 pass the monorail crane track inside the double track section 251 as they move from the goaf to the loading zone.
Specifically, the monorail crane rail outside the double-rail section 251 refers to a monorail crane rail on the left side of the advancing direction when the bulk bag train moves from the loading area to the goaf side, and the monorail crane rail inside the double-rail section 251 refers to a monorail crane rail on the left side of the advancing direction when the bulk bag train moves from the goaf to the loading area side. Therefore, the multiple rows of freight bag trains running in opposite directions run towards the left, and mutual influence of the multiple rows of freight bag trains in running is avoided.
