[0038] In an optional implementation manner of the embodiment of the present invention, as Figure 5 As shown, the pipeline positioning bracket 12 is provided with grooves having the same diameter as the pipeline, and the grooves are separated by a certain distance.

[0039] In an optional implementation manner of the embodiment of the present invention, as Figure 5 As shown, the transmission belt 14 is concave in the middle and high on both sides, and the surface of the transmission belt 14 is made of frosted material, so that the filler will not fall to the sides during transportation.

[0040] Working principle: When the present invention is in use, a submerged pipe method is adopted to fill and manage the coal mining goaf to prevent ground collapse, and water can be stored and utilized in the pipe. Due to the huge project, the device adopts a mechanically integrated filling and installation method, and the filler is transmitted to the compaction and molding mechanism through the transmission belt 14, and the filler is compacted by the compaction and molding mechanism, and the filler is compacted section by section, and finally the pipe is pushed to the compacted filler through the pipe positioning bracket 12 for laying, which greatly saves human resources and improves the equipment installation efficiency; the various mechanisms of the device can be adjusted, and the compaction and molding mechanism can be lifted after compaction to prevent blocking the pipeline transportation, and the transportation mechanism can be lowered to a certain height after transportation is completed, which also makes room for pipeline transportation.

[0041] When the device is in use, the device is moved to the deepest part of the goaf, and the telescopic plate 4 is first unfolded to keep it consistent with the width of the space, so as to prevent the filling from spreading. The stepper motor I10 is started to drive the worm 9 to rotate, thereby driving the worm wheel 8 to rotate, and driving the connecting ring 5 to rotate through the transmission shaft 7. The connecting ring 5 drives the telescopic plates 4 on both sides to extend through the connecting rod 6 to keep it consistent with the width of the space;

[0042] Next, use other small transport tools to pour the filler onto the transmission belt 14, and the stepper motor II 17 is started to drive the transmission belt 14 to rotate, thereby transmitting the filler to the front of the baffle 3. The baffle 3 and the telescopic plate 4 are used to intercept the filler to prevent it from extending during compaction. At this time, the output end of the transmission belt 14 is higher than the baffle 3 and extends forward a section. When the filler is as high as the baffle 3, the compaction molding mechanism is started, and the stepper motor IV 32 is started to drive the driven gear 30 to rotate, thereby driving the eccentric rod 29 to rotate. The eccentric rod 29 drives the slide frame 28 to move up and down, thereby driving the movable plate 25 to move up and down, so that the pressing plate 26 reciprocates to compact the filler and compact it into a semicircular shape, which is convenient for the subsequent placement of the pipeline. After compaction, the highest surface of the filler will be compressed and dropped, and the conveying filler is repeatedly compacted until the compacted height is consistent with the baffle 3. Stop, next, the device moves outward a section, and then performs the feeding and compaction steps until the length of a pipeline is reached;

[0043] Next, the stepper motor III 21 starts to drive the slide rail 20 to slide, thereby driving the side bracket 13 to slide, so that the output end of the transmission belt 14 moves backward, away from the baffle 3, and then the hydraulic cylinder I 19 starts, the piston rod contracts inward, and the lower end of the support rod 18 slides toward the cylinder body of the hydraulic cylinder I 19. The main bracket 11 moves downward under the action of its own weight. At this time, the output short of the transmission belt 14 also drops to below the highest point of the baffle 3, thereby making room for the transportation of the pipeline. At the same time, the hydraulic cylinder II 23 starts to drive the double support arm 22 to lift up, thereby driving the compaction molding machine The structure is lifted, which also makes room for the transportation of the pipeline; in the next step, other auxiliary tools are used to place the pipeline on the pipeline positioning bracket 12, and then the pipeline is pushed forward and pushed onto the compacted filling material. Note that there are sealing rings at the joints between the pipelines, which can be snapped in when docking, and one end of the first batch of pipelines pushed in is sealed, and the last batch of pipelines are provided with water suction pipes and ventilation pipes extending to the ground, thereby completing the placement and filling of the main pipelines, and finally injecting the stimulating quick-setting expansion waste slag glue solid material into the upper side of the pipeline and the top of the goaf.
