Description

Technical Field

[0001] This invention relates to the field of grouting equipment technology, and in particular to a grouting equipment for geological disaster control. Background Technology

[0002] The grouting equipment currently used for geological disaster control mainly uses a motor at the top of the material tank to drive a rotating shaft and mixing blades to prevent the material inside the tank from solidifying. A pressure pump provides pressure, and cement enters the discharge pipe through a hose and is finally sprayed onto the required location. When the motor starts, the vibrating rod vibrates, causing the cement to fill every corner. After use, rotating the handle separates the fixing cap from the material tank for easy cleaning.

[0003] When the above-mentioned grouting device encounters a small crack, it is difficult to penetrate into it and cannot effectively fill the crack. Furthermore, when only cement is used, the connection between the solidified grout and the crack is relatively loose, making it prone to secondary cracking when subjected to external forces.

[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of the present invention, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0028] Please see Figures 1 to 5 ,.like Figures 1-5 The diagram shown illustrates the structure of a grouting device for geological disaster control, according to an embodiment of the present invention. The grouting device may include a material delivery pipe 1, a fixed baffle 2, an automatic telescopic mechanism, an elastic adjustment mechanism, and a longitudinal material discharge mechanism.

[0029] The filling cone 5 is connected to the top of the conveying pipe 1. The fixed baffle 2 is arranged on the outside of the conveying pipe 1 and is fixedly connected to the conveying pipe 1 so as to suspend the conveying pipe 1 on the ground at the top of the crack.

[0030] An automatic telescopic mechanism is installed inside the conveying pipe 1. This mechanism moves synchronously with the filling slurry entering the conveying pipe 1 along the filling cone 5, thus achieving an automatic retraction function. For example, when the filling slurry entering the conveying pipe 1 moves along... Figure 2 When the feed tube moves from top to bottom, the automatic telescopic mechanism also moves in the same direction. In some embodiments, the automatic telescopic mechanism is located at the bottom of the feed tube 1.

[0031] The elastic adjustment mechanism is installed on the feed pipe 1. One end of the elastic adjustment mechanism is hinged to the movable plate 6 in the automatic telescopic mechanism, which is used to push the elastic adjustment mechanism located on the side to move synchronously when the automatic telescopic mechanism is working.

[0032] The longitudinal feeding mechanism is arranged inside the feed pipe 1 and is used to add reinforcements into the gap during the process of conveying the filling slurry.

[0033] In one embodiment of the present invention, the fixed baffle 2 is provided with a connecting hole 3, and the material conveying pipe 1 and the fixed baffle 2 are fixed by screws 4; the fixed baffle 2 is also equipped with an operating platform 25, which is electrically connected to an external delivery pump to facilitate adjustment of the grouting flow rate; in addition, the reinforcement components involved in this application, in addition to the metal strip 23 listed in the embodiments, can also be steel bars, etc., to cooperate with concrete in order to improve the structural strength after the grout solidifies.

[0034] like Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the automatic telescopic mechanism includes a movable plate 6, an arc-shaped sleeve 7, a first elastic support member 8, a longitudinal rod 9, a movable rod 10, and a guide tube 11.

[0035] The movable plates 6 are arranged in pairs and staggered inside the conveying pipe 1, and the ends of two adjacent movable plates 6 are hinged. An arc-shaped sleeve 7 is arranged between the movable plates 6 and the inner wall of the conveying pipe 1, and a first elastic support member 8 is installed inside the arc-shaped sleeve 7.

[0036] The bottom of the movable plate 6 is also equipped with a longitudinal rod 9. The bottom of the longitudinal rod 9 is hinged to two movable rods 10. The free end of the movable rod 10 is hinged to an outlet pipe 11. The outlet pipe 11 is slidably connected to the through hole 12 opened on the side of the conveying pipe 1.

[0037] In one embodiment of the invention, the conveying pipe 1 is placed in a crack caused by a geological disaster as needed. Once a specified depth is reached, the external conveying pump is activated via the control platform 25. Grout enters the conveying pipe 1 along the filling cone 5, and during the grout flow, it pushes two movable plates 6 to swing horizontally. The movable plates 6 push the longitudinal rod 9 to move longitudinally, and the longitudinal rod 9 pushes the movable rods 10 on both sides of the bottom end to swing horizontally. The movable rods 10 push the outlet pipe 11 to slide along the through hole 12 on the conveying pipe 1, causing the outlet pipe 11 to extend out of the conveying pipe 1, and the grout is injected into the crack along the outlet pipe 11. When the grout flow rate changes, the first elastic support 8 undergoes elastic deformation under force, and after grouting is completed, the movable plate 6 returns to its initial position under the action of the first elastic support 8. The movable plate 6 then pulls the outlet pipe 11 back into the conveying pipe 1 through the arranged longitudinal rod 9 and movable rods 10, thereby achieving an automatic retraction function.

[0038] like Figure 2 and Figure 5 As shown, in another preferred embodiment of the present invention, the elastic adjustment mechanism includes an L-shaped rod 13, a fixed rod 16, a movable flap 17, a limiting post 18, and a limiting groove 19.

[0039] The L-shaped rod 13 is hinged to the outside of the movable plate 6. A fixing rod 16 is fixedly installed at the bottom end of the L-shaped rod 13, and a limit stake 18 is fixedly installed at the bottom end of the fixing rod 16.

[0040] The movable flap 17 is hinged to the outside of the conveying pipe 1. A limiting groove 19 is opened inside the movable flap 17, and the limiting groove 19 is slidably connected to the limiting pile 18.

[0041] In one embodiment of the invention, the L-shaped rod 13 is radially slidably connected to the conveying pipe 1. When the movable plate 6 swings planarly within the conveying pipe 1, the movable plate 6 pushes the L-shaped rods 13 on both sides to slide horizontally along the conveying pipe 1, while the L-shaped rods 13 on both sides slide in opposite directions. The L-shaped rods 13 then pull the fixed rod 16 and the limiting stake 18 arranged at the bottom to move synchronously. At the same time, the limiting stake 18 slides along the limiting groove 19 opened on the movable flap 17, while the movable flap 17 itself swings along the outside of the conveying pipe 1, adjusting the tilt angle of the movable flap 17 to change the trajectory of the metal strip 23, so that the metal strip 23 is stably inserted into the mud.

[0042] like Figure 1 , Figure 2 and Figure 5 As shown, in another preferred embodiment of the present invention, the elastic adjustment mechanism further includes a stop bar 14 and a second elastic support member 15.

[0043] The stop bar 14 is hinged to the inside of the L-shaped rod 13, and the end of the stop bar 14 is provided with a smooth part.

[0044] A second elastic support 15 is fixedly installed on the inner side of the L-shaped rod 13, and the end of the second elastic support 15 is fixedly connected to the stop bar 14.

[0045] In one embodiment of the present invention, a receiving groove 20 is provided on the outer side of the conveying pipe 1 so that the retracted movable flap 17 can be embedded therein, maintaining the integrity of the structure and effectively preventing the device from being easily picked up during placement due to the protruding structure.

[0046] In use, the baffle 14 and the second elastic support 15 move radially along the feed pipe 1 with the L-shaped rod 13. When adjusted to the designated position, the baffle 14 stops moving. When the metal strip 23 slides along the longitudinal flow channel 21 and the transition flow channel 22 and slides to the end of the feed pipe 1, the part that jumps up contacts the baffle 14. In this state, the second elastic support 15 is subjected to force and undergoes elastic deformation. After the grouting is completed, when the movable flap 17 is embedded in the receiving groove 20, the baffle 14 contacts the feed pipe 1 and the second elastic support 15 is in a compressed state.

[0047] like Figure 1 , Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the longitudinal feeding mechanism includes a longitudinal flow channel 21, a transition flow channel 22, a metal strip 23, and a cone 24.

[0048] The longitudinal flow channel 21 and the transition flow channel 22 are arranged along the axial direction of the conveying pipe 1, and the longitudinal flow channel 21 and the transition flow channel 22 are connected.

[0049] A metal strip 23 is installed at the top of the feed pipe 1 at the position corresponding to the longitudinal flow channel 21, for adding the metal strip 23 into the feed pipe 1.

[0050] In one embodiment of the present invention, during the grouting process, multiple metal strips 23 are sequentially fed into the feed pipe 1 along the cone 24. Under the action of gravity, the metal strips 23 move along the longitudinal flow channel 21 and the transition flow channel 22. When they reach the end of the transition flow channel 22, they jump outward under the action of inertia and are then inserted into the grout after being adjusted by the baffle 14 and the movable flap 17.

[0051] In summary, this invention involves transporting the device to the location of a geological fracture, inserting the conveying pipe 1 into the fracture, and controlling the operating platform 25 to activate the external conveying pump. The slurry enters the conveying pipe 1 along the injection cone 5, and during the slurry flow, it pushes two movable plates 6 to swing horizontally. The movable plates 6, on one hand, push the longitudinal rod 9 to move longitudinally, and on the other hand, push the movable rods 10 on both sides of the bottom end to swing horizontally. The movable rods 10 push the outlet pipe 11 to slide along the through hole 12 on the conveying pipe 1, causing the outlet pipe 11 to extend out of the conveying pipe 1. The slurry flows along the outlet pipe 11... When the slurry is injected into the gap, and the flow rate of the slurry changes, the first elastic support 8 undergoes elastic deformation under stress. The movable plate 6 pushes the L-shaped rods 13 on both sides to slide horizontally along the conveying pipe 1, while the L-shaped rods 13 on both sides slide in opposite directions. The L-shaped rods 13 pull the fixed rod 16 and the limiting pile 18 arranged at the bottom to move synchronously. At the same time, the limiting pile 18 slides along the limiting groove 19 opened on the movable flap 17, while the movable flap 17 itself swings along the outside of the conveying pipe 1, adjusting the tilt angle of the movable flap 17, and sequentially moving the multiple metal strips 23. The metal strip 23 is fed into the conveying pipe 1 along the cone 24. Under the action of gravity, it moves along the longitudinal flow channel 21 and the transition flow channel 22, and falls on the movable flap 17 when it reaches the end of the transition flow channel 22. The metal strip 23 slides along the movable flap 17, and when it reaches the end, it jumps outward under the action of inertia. Under the action of the baffle 14 and the movable flap 17, it is stably inserted into the mud. As the slurry fills, the conveying pipe 1 can be pulled outward. The above process is repeated to complete the filling of the geological fracture. When the grouting is stopped, the movable plate 6 is supported by the first elastic support. Under the action of 8, it returns to the initial position, while the movable plate 6 pulls the outlet pipe 11 back into the conveying pipe 1 through the arranged longitudinal rod 9 and movable rod 10, and the movable flap 17 is embedded in the receiving groove 20. This device can automatically adjust the extension and contraction state according to the grouting process. On the one hand, it does not need to increase the internal structure by expanding the diameter of the conveying pipe 1, thus adapting to geological cracks of different widths and improving the applicability of the device. On the other hand, it can add multiple metal strips 23 to the grout in sequence during grouting, which can enhance the structural strength of the grout after solidification and avoid subsequent cracking.
