Description

Technical Field

[0001] The invention relates to the technical field of grouting devices, and in particular to a high-efficiency grouting device and method for mine reinforcement materials. Background Art

[0002] The grouting device for polymer materials in coal mines is used to mix and pressure-feed different components of reactive polymer materials in coal mines for grouting. It is suitable for grouting in underground coal mines, reinforcing coal rock cracks, filling confined spaces, spraying to plug air leaks, reinforcing unstable coal seams, and reinforcing and repairing broken roofs in tunnels.

[0003] When the grouting device in the prior art mixes different components of the polymer material, it is usually mixed in a tank first, and then poured into the borehole through a grouting pipe. For example, the existing patent CN202321032459.0 discloses a high-efficiency grouting device for coal mine grouting, including a slurry mixing box, a feed port is provided at the upper end of the slurry mixing box, a raw material processing box fixed in the slurry mixing box is provided below the feed port, a processing chamber is provided in the raw material processing box, a raw material processing mechanism is provided in the processing chamber, and a stirring mechanism is provided below the raw material processing mechanism.

[0039] Example

[0040] See also Figures 1 to 7 As shown in the figure, the present invention provides an efficient grouting device for mine reinforcement materials, including a supporting mechanism 1, a pneumatic grouting pump 2 is provided on the top of the supporting mechanism 1, the pneumatic grouting pump 2 provides power for the grouting device, and a plurality of working cylinders are connected to the bottom of the pneumatic grouting pump 2, the feed ports of the plurality of working cylinders are respectively connected to one end of a grouting pipe through a connector 8, the other end of the grouting pipe is connected to a slurry storage tank in the prior art, and the plurality of working cylinders are respectively connected to corresponding slurry storage tanks through the grouting pipes, thereby facilitating the separate transportation of polymer material components in different slurry storage tanks without mixing them in advance, thereby avoiding premature contact and reaction of different polymer material components.

[0041] The discharge port of the working cylinder is connected to one end of the grouting pipe through the four-way joint 9, and the other end of the grouting pipe is connected to one end of the mixing mechanism 11 through the control valve mechanism 10. The other end of the mixing mechanism 11 is connected to the grouting head 12. The slurry in different working cylinders is respectively transported to one end of the grouting head 12 through the grouting pipes. The mixing mechanism 11 is arranged on the front side of the grouting head 12, so that the polymer material components are fully mixed before entering the drill hole, so as to facilitate the full reaction of different polymer material components and improve the grouting effect.

[0042] The support mechanism 1 includes a support frame 101, a grouting pump fixing plate 102, a working cylinder fixing plate 103 and an adjusting foot 104. The grouting pump fixing plate 102 is arranged in the middle of the support frame 101, the working cylinder fixing plate 103 is connected to the lower side of the grouting pump fixing plate 102 through a connecting rod 105, and the adjusting foot 104 is connected to the bottom of the support frame 101. The support mechanism 1 provides stable support for the grouting device to ensure the stability of the grouting device.

[0043] The adjustment foot 104 includes a support rod 1041 and a support seat 1042. The support seat 1042 is fixedly connected to the bottom of the support rod 1041. An adjustment cavity 1043 is provided in the middle of the support rod 1041. A bevel gear 1044 is provided in the adjustment cavity 1043. The bevel gear 1044 is connected to the adjustment cavity 1043 through a bearing. One side of the bevel gear 1044 is meshed with a bevel gear 2 1045. The bevel gear 2 1045 is connected to an adjustment handle 1047 on the outside of the adjustment cavity 1043 through a connecting rod 2 1046. The bevel gear 2 1045 is driven to rotate by rotating the adjustment handle 1047, and the bevel gear 1 1044 is driven to rotate by the bevel gear 2 1045.

A limiting block 10410 is also fixedly connected to the lower side of the adjustment cavity 1043, and a limiting slide groove 10411 is provided in the middle of the limiting block 10410. A limiting bar 10412 slidably connected to the limiting slide groove 10411 is provided on the lower side of the telescopic rod 1049.

[0044] The bottom of the telescopic rod 1049 is a cone-tip structure, and a through hole slidably connected to the cone-tip structure is provided in the middle of the support seat 1042. When the cone-tip structure does not extend out of the support seat 1042, it directly contacts the ground through the support seat 1042 to provide support for the support mechanism 1. When the cone-tip structure extends to the outside of the support seat 1042, the cone-tip structure can be inserted into the ground to improve the stability of the support mechanism 1, so that it can be used in grouting areas with rugged ground, further improve the stability of the grouting device, and prevent the grouting device from tipping over during the grouting process, affecting the grouting effect and causing waste of grouting materials.

[0045] There are three working cylinders including working cylinder 1 3, working cylinder 2 4, and working cylinder 3 5. The grouting pipes include grouting pipe 1 6 and grouting pipe 2 7. Working cylinder 1 3 is connected with transition pipe 1 13 through a four-way joint 9, working cylinder 3 5 is connected with transition pipe 2 14 through a four-way joint 9, transition pipe 1 13 and transition pipe 2 14 are connected with grouting pipe 1 6 through a three-way joint 18, and working cylinder 2 4 is connected with grouting pipe 2 7 through a four-way joint 9. It can be applied to the mixing of three components. When in use, the working cylinder 1 3 and the working cylinder 3 5 can be connected with the storage tanks of two polymer material components which do not produce foaming reaction or react slowly, and the working cylinder 2 4 can be connected with the storage tank of the catalytic material component, so that the two polymer material components first enter the grouting pipe 1 6 through the transition pipe 1 13 and the transition pipe 2 14 to be mixed, and then are mixed with the catalytic material component transported through the grouting pipe 2 7 to react. While avoiding the premature reaction of the polymer material components, it also ensures the full mixing of multiple components, thereby ensuring the smooth grouting and the effect of the grouting.

[0046] The four-way joint 9 is also connected to a pressure gauge 15 and a safety valve 16. The pressure at the four-way joint 9 can be monitored by the pressure gauge 15, and then the pressure at the four-way joint 9 can be adjusted by the safety valve 16 to avoid pipeline rupture due to excessive pressure and reduce safety hazards.

[0047] The grouting pipe 1 6 and the grouting pipe 2 7 are both provided with a control valve mechanism 10, and the control valve mechanisms 10 on the grouting pipe 1 6 and the grouting pipe 2 7 are both connected to the mixing mechanism 11 through the special-shaped tee 17. The control valve mechanism 10 can control the opening and closing of the grouting pipe 1 6 and the grouting pipe 2 7, so as to selectively control whether the materials in the grouting pipe 1 6 and the grouting pipe 2 7 enter the mixing mechanism 11 for mixing.

[0048] The control valve mechanism 10 includes a valve 1001, a valve 1002, a three-way joint 1003, a check valve 1004 and a direct joint 1005.

The three-way joint 1003 is also connected to the valve 1002. The valve 1001 on the grouting pipe 27 is connected to one end of the three-way joint 1003, and the other end of the three-way joint 1003 is connected to one end of the check valve 1004 through the direct joint 1005. The three-way joint 1003 is also connected to the valve 1002, and the other end of the check valve 1004 is connected to the special-shaped three-way 17. The setting of the one-way valve 1004 can prevent the fluid in the grouting pipe 1 6 or the grouting pipe 2 7 from flowing back. The setting of the valve 2 1002 can connect other pipes at the three-way joint 2 1003, so as to facilitate the introduction of other materials for mixing before the mixing mechanism 11, thereby expanding the application scope of the grouting device.

[0049] The mixing mechanism 11 includes a plurality of mixing tubes 1101, and a plurality of alternately arranged left-handed blades 1102 and right-handed blades 1103 are provided in the middle of the mixing tube 1101, and the left-handed blades 1102 and the right-handed blades 1103 are fixedly connected to the inner wall of the mixing tube 1101. After the fluids in the grouting tube 1 6 and the grouting tube 2 7 enter the mixing mechanism 11, the two fluids are fully mixed by the shearing action of the left-handed blades 1102 and the right-handed blades 1103, thereby achieving full mixing of different polymer material components.

[0050] The grouting head 12 includes a grouting end 1201 and a connecting end 1202. The grouting head 12 is connected to the grouting pipe through the connecting end 1202. A groove 1203 is provided in the middle of the grouting end 1201 and the connecting end 1202. An annular airbag 1204 is fixedly connected in the groove 1203. An air inlet valve 1205 is provided on the annular airbag 1204. After the grouting head 12 is inserted into the borehole, air is inflated into the annular airbag 1204 through the air inlet valve 1205 to expand it, so that the grouting head 12 is easily clamped in the borehole, and the phenomenon of the grouting head 12 falling off due to excessive pressure when the fluid mixture flows from the mixing mechanism 11 into the grouting head 12 is prevented, thereby improving the stability of the grouting head 12.

[0053] Start the pneumatic grouting pump 2, so that the polymer material components and the catalytic components enter the working cylinder 1 3, the working cylinder 2 4, and the working cylinder 3 5 respectively. The polymer material components in the working cylinder 1 3 and the working cylinder 3 5 enter the grouting pipe 1 6 through the transition pipe 1 13 and the transition pipe 2 14 respectively for mixing. The catalytic component in the working cylinder 2 4 enters the grouting pipe 2 7. Then the mixture in the grouting pipe 1 6 and the catalytic component in the grouting pipe 2 7 enter the mixing mechanism 11 for mixing. Finally, the slurry mixed by the mixing mechanism 11 is poured into the borehole through the grouting head 12 for curing reaction to complete the grouting operation.
