Description

Technical Field

[0001] The invention relates to the technical field of coal mine goaf filling, and in particular to goaf filling management equipment. Background Art

[0002] In underground tunnels such as coal mines and metal mines, goafs are often long and narrow (length > 100m, cross-sectional width < 3m). Traditional filling processes require the installation of fixed ground rails along the tunnels and the laying of rigid conveying pipelines (pipe diameter 200-300mm). In order to ensure the filling density, the goaf needs to be divided into multiple independent operation sections (10-15m per section). After completing the filling of a single section, the pipeline needs to be disassembled and repositioned and installed. A single disassembly takes up to 30-45 minutes. According to statistics, in steeply inclined coal seam tunnels with a cross-sectional width of only 1.5m, the pipeline movement operation time accounts for more than 60% of the overall construction cycle, which seriously restricts the efficiency of large-scale governance. More importantly, frequent disassembly can easily lead to wear of pipeline joints (the probability of sealing failure increases by 22%), causing slurry leakage to pollute the tunnel, further raising the operation and maintenance costs.

[0003] A single system needs to be equipped with a pressure valve (control range 0.2-1.5MPa), a directional valve (response time > 2s) and a flow valve (accuracy ±15%), with a power consumption of 5-8kW / h and an independent PLC control system, increasing the equipment purchase cost by more than 40%.

The main transmission component 4042 and the auxiliary transmission component 4043 are meshed with each other, thereby achieving the effect of meshing transmission.

[0062] Specifically, the steps of filling and treating the goaf are as follows: the slurry for filling is filled into the storage tank 10, the evenly mixed slurry is transported to the transport pipe 20, and then the plugging component 30 is controlled to control the slurry to be transported to the feeding component 40 during the process of grouting and filling the goaf. The feeding component 40 is set on the mobile leveling and pressing component 50, and the filling and treating of the goaf is realized as the mobile leveling and pressing component 50 moves.

[0063] The steps of controlling the slurry from the conveying pipe 20 into the feeding assembly 40 through the plugging assembly 30 are as follows: first, before grouting, the fixed cover 4011 is driven to move to the grouting area by moving the flat pressing assembly 50. The adjusting screw 4023 is rotated on the connecting pipe 4021, and the adjusting screw 4023 drives the limit slider 4024 to move horizontally, so that the limit slider 4024 and the sealing baffle 4025 are separated. Then the sealing baffle 4025 is removed from the connecting pipe 4021, and the connecting pipe 4021 is located directly below the plugging assembly 30, and then the plugging assembly 30 and the connecting pipe 4021 are docked.

[0064] The first driving component 3023 is operated, and the first driving component 3023 gradually separates from the limiting block 3042 during operation, and the inner sleeve 3031 gradually moves downward. During the downward movement of the inner sleeve 3031, the top block 3034 abuts against the blocking component 3014, and the blocking component 3014 is pushed out from the material hole 3035. The inner sleeve 3031 is inserted into the connecting pipe 4021, and the inner sleeve 3031 is limited by the limiting partition 3032. At this time, the adjusting screw 4023 is rotated again to make the limiting slider 4024 abut against the surface of the inner sleeve 3031 to enhance the stability of the inner sleeve 3031. The slurry enters the connecting pipe 4021 from the material hole 3035, and in order to ensure good sealing, a sealing gasket with interference fit is provided at the connection between the inner wall of the connecting pipe 4021 and the inner sleeve 3031. Thus, the slurry is transported to the feeding assembly 40.

[0065] The steps of filling the slurry are: operate the third driving component 4041, the third driving component 4041 drives the main transmission component 4042 to rotate during operation, the main transmission component 4042 and the auxiliary transmission component 4043 are meshed and connected, and then drive the conveying auger 4013 to rotate. The conveying auger 4013 drives the slurry to be transported during the rotation, and the slurry is filled into the goaf area through the material pipe 405 and intercepted by the pressing plate 505. During the slurry filling process, operate the second driving component 503, and then push the pressing plate 505 to flip, so that the pressing plate 505 is pressed against the slurry surface, so that the slurry partially fills the goaf area, and after solidification, move the moving bottom plate 501 to fill the local space of the next goaf area.

[0066] When replacing the local space to be filled, firstly, the limiting slider 4024 is separated from the inner sleeve 3031, and then the first driving component 3023 is operated again, and the first driving component 3023 pushes the lifting component 3024 to move, and then the lifting component 3024 is again connected with the limiting block 3042, so that the inner sleeve 3031 moves upward. During the rising process of the inner sleeve 3031, the blocking component 3014 is connected with the material hole 3035 through the reset component 3013, so that the slurry is blocked. When the material hole 3035 is blocked, the inner sleeve 3031 is separated from the connecting pipe 4021. At this time, the fixed cover 4011 is driven to move by the moving bottom plate 501, so that the next connecting pipe 4021 on the fixed cover 4011 moves to the bottom of the inner sleeve 3031.

[0067] In summary, the goaf filling and management equipment according to the embodiment of the present invention replaces the traditional electric control valve with a pure mechanical linkage structure, eliminates dependence on electricity, realizes the "dismantle and connect" operation of pipeline relocation, and effectively fills and manages the goaf.

[0068] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and deform the above embodiments within the scope of the present invention.
