Description

Technical Field

[0001] The invention relates to the technical field of grouting devices, and in particular to a grouting device used for geological disaster management. Background Art

[0002] The grouting device currently used for geological disaster control mainly uses the engine at the top of the material box to drive the rotating shaft and the stirring blade to rotate to prevent the material in the material box from solidifying. The pressure pump provides pressure, and the cement enters the discharge pipe from the hose and is finally sprayed to the required position. The engine starts the vibration rod to vibrate, so that the cement fills every corner. After use, turn the handle to separate the fixing cap from the material box to facilitate the subsequent cleaning of the material box.

[0003] When encountering smaller cracks, the above-mentioned grouting device is difficult to extend into the cracks and cannot effectively fill the inside of the cracks. In addition, when only cement is used, the connection between the solidified slurry and the cracks is loose, and secondary cracking is prone to occur when subjected to external force.

[0023] See also Figures 1 to 5 ,.like Figure 1-Figure 5 FIG. 1 is a structural diagram of a grouting device for geological disaster management provided by an embodiment of the present invention. The grouting device may include a feed pipe 1, a fixed baffle 2, an automatic telescopic mechanism, an elastic adjustment mechanism and a longitudinal discharge mechanism.

[0024] The filling cone 5 is connected to the top of the feed pipe 1. The fixed baffle 2 is arranged outside the feed pipe 1, and the fixed baffle 2 is fixedly connected to the feed pipe 1, so as to hang the feed pipe 1 on the ground at the top of the crack.

[0025] The automatic telescopic mechanism is arranged in the feeding pipe 1, and the automatic telescopic mechanism moves synchronously with the filling slurry entering the feeding pipe 1 along the filling cone 5 to realize the automatic contraction function. Figure 2 When the material conveying pipe 1 moves from top to bottom, the automatic telescopic mechanism also moves along with the automatic telescopic mechanism. In some embodiments, the automatic telescopic mechanism is arranged at the bottom of the material conveying pipe 1.

[0026] The elastic adjustment mechanism is installed on the feeding pipe 1, and one end of the elastic adjustment mechanism is hinged to the movable plate 6 in the automatic telescopic mechanism, so as to push the elastic adjustment mechanism located on the side to move synchronously when the automatic telescopic mechanism is working.

[0027] The longitudinal discharge mechanism is arranged inside the conveying pipe 1 and is used to add reinforcement members into the gap during the process of conveying the filling slurry.

[0028] In one example of the present invention, a connecting hole 3 is provided on the fixed baffle 2, and the feed pipe 1 and the fixed baffle 2 are fixed by screws 4; an operating platform 25 is also installed on the fixed baffle 2, and the operating platform 25 is electrically connected to an external delivery pump to facilitate adjustment of the grouting flow rate; in addition, in addition to the metal strips 23 listed in the embodiment, the reinforcement members involved in the present application can also be steel bars, etc., which are used in combination with concrete to improve the structural strength after the slurry solidifies.

[0029] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the automatic telescopic mechanism includes a movable plate 6, an arc sleeve 7, a first elastic support member 8, a longitudinal rod 9, a movable rod 10 and a guide tube 11.

[0030] The movable plates 6 are staggered in pairs in the feed pipe 1 , and the ends of two adjacent movable plates 6 are hinged. An arc sleeve 7 is arranged between the movable plate 6 and the inner wall of the feed pipe 1 , and a first elastic support member 8 is installed inside the arc sleeve 7 .

[0031] A longitudinal rod 9 is also installed at the bottom end of the movable plate 6. Two movable rods 10 are hinged at the bottom end of the longitudinal rod 9. A guide pipe 11 is hinged at the free end of the movable rod 10. The guide pipe 11 is slidably connected to a through hole 12 opened on the side of the feed pipe 1.

[0032] In one embodiment of the present invention, when in use, the feed pipe 1 is placed in the crack caused by geological disasters as needed. When the specified depth is reached, the external delivery pump is operated by controlling the operating platform 25, and the slurry enters the feed pipe 1 along the filling cone 5, and pushes the two movable plates 6 to swing in the plane during the flow of the slurry. On the one hand, the movable plate 6 pushes the longitudinal rod 9 to move in the longitudinal direction, and the longitudinal rod 9 pushes the movable rods 10 on both sides of the bottom to swing in the plane. The movable rod 10 pushes the outlet pipe 11 to slide along the through hole 12 opened on the feed pipe 1, so that the outlet pipe 11 extends out of the feed pipe 1, and the slurry is filled into the gap along the outlet pipe 11. When the slurry flow rate changes, the first elastic support member 8 is elastically deformed by force, and after the grouting is completed, the movable plate 6 returns to the initial position under the action of the first elastic support member 8. The movable plate 6 pulls the outlet pipe 11 back into the feed pipe 1 through the longitudinal rod 9 and the movable rod 10 arranged, thereby realizing the automatic contraction function.

[0033] like Figure 2 and Figure 5 As shown, as 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 pile 18 and a limiting groove 19 .

[0034] The L-shaped rod 13 is hinged to the outer side of the movable plate 6 , and a fixing rod 16 is fixedly installed at the bottom end of the L-shaped rod 13 , and a limiting pile 18 is fixedly installed at the bottom end of the fixing rod 16 .

[0035] The movable flap 17 is hinged on the outside of the material conveying pipe 1 , and a limiting groove 19 is provided inside the movable flap 17 , and the limiting groove 19 is slidably connected to the limiting pile 18 .

[0036] In one embodiment of the present invention, the L-shaped rod 13 is connected to the feed pipe 1 in a radially sliding manner. When the movable plate 6 performs a plane swing in the feed pipe 1, the movable plate 6 pushes the L-shaped rods 13 on both sides to slide horizontally along the feed pipe 1, and the L-shaped rods 13 on both sides slide in opposite directions. The L-shaped rod 13 pulls the fixed rod 16 and the limit pile 18 arranged at the bottom to move synchronously. At the same time, the limit pile 18 slides along the limit groove 19 provided on the movable flap 17, and the movable flap 17 itself swings along the outer side of the feed pipe 1, and the inclination angle of the movable flap 17 is adjusted to change the movement trajectory of the metal strip 23, so that the metal strip 23 can be stably inserted into the mud.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, as another preferred embodiment of the present invention, the elastic adjustment mechanism further includes a blocking bar 14 and a second elastic support member 15 .

[0038] The blocking bar 14 is hinged to the inner side of the L-shaped rod 13 , and a smooth portion is provided at the end of the blocking bar 14 .

[0039] A second elastic support member 15 is fixedly mounted on the inner side of the L-shaped rod 13 , and an end of the second elastic support member 15 is fixedly connected to the blocking bar 14 .

[0040] In one embodiment of the present invention, a receiving groove 20 is provided on the outer side of the feed pipe 1 to allow the retracted movable flap 17 to be embedded therein, thereby maintaining the integrity of the structure and effectively preventing the protruding structure from hindering the smooth removal of the device during placement.

[0041] When in use, the baffle 14 and the second elastic support member 15 move radially along the feed pipe 1 with the L-shaped rod 13. When adjusted to the specified position, the baffle 14 stops moving, and the metal bar 23 slides along the longitudinal flow channel 21 and the transition flow channel 22, and when it slides to the end and extends out of the feed pipe 1, the jumped part contacts the baffle 14. In this state, the second elastic support member 15 is elastically deformed under the force, and 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 member 15 is in a compressed state.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, as another preferred embodiment of the present invention, the longitudinal discharge mechanism includes a longitudinal flow channel 21, a transition flow channel 22, a metal strip 23 and a cone 24.

[0043] The longitudinal flow channel 21 and the transition flow channel 22 are arranged along the axial direction of the material conveying pipe 1, and the longitudinal flow channel 21 and the transition flow channel 22 are communicated with each other.

[0044] A metal strip 23 is installed at the top of the material delivery pipe 1 at a position corresponding to the longitudinal flow channel 21 , so as to add the metal strip 23 into the material delivery pipe 1 .

[0045] In one embodiment of the present invention, during the grouting process, a plurality of metal strips 23 are sequentially fed into the feed pipe 1 along the cone 24. The metal strips 23 move along the longitudinal flow channel 21 and the transition flow channel 22 under the action of gravity, and when they move to the end of the transition flow channel 22, they jump outward under the action of inertia and are guided out, and are inserted into the slurry after being adjusted by the baffle bar 14 and the movable flap 17.

[0046] In summary, the present invention transports the device to the geological fracture position, extends the feed pipe 1 into the fracture, and controls the operation platform 25 to make the external delivery pump work, so that the slurry enters the feed pipe 1 along the filling cone 5, and pushes the two movable plates 6 to swing in the plane during the flow of the slurry. On the one hand, the movable plate 6 pushes the longitudinal rod 9 to move in the longitudinal direction, and the longitudinal rod 9 pushes the movable rods 10 on both sides of the bottom to swing in the plane. The movable rods 10 push the outlet pipe 11 to slide along the through hole 12 opened on the feed pipe 1, so that the outlet pipe 11 extends out of the feed pipe 1, and the slurry flows along the outlet pipe 11. When the slurry is poured into the gap, when the slurry flow rate changes, the first elastic support member 8 is subjected to elastic deformation, and the movable plate 6 pushes the L-shaped rods 13 on both sides to slide horizontally along the feeding pipe 1, and the L-shaped rods 13 on both sides slide in opposite directions, and the L-shaped rods 13 pull the fixed rods 16 and the limit piles 18 arranged at the bottom to move synchronously. At the same time, the limit piles 18 slide along the limit grooves 19 provided on the movable flap 17, and the movable flap 17 itself swings along the outer side of the feeding pipe 1, and the inclination angle of the movable flap 17 is adjusted, and the multiple metal strips 23 are sequentially moved. The metal strip 23 is fed into the feed pipe 1 along the cone 24. The metal strip 23 moves along the longitudinal flow channel 21 and the transition flow channel 22 under the action of gravity, and falls on the movable flap 17 when it moves to the end of the transition flow channel 22. The metal strip 23 slides along the movable flap 17, and jumps outwards under the action of inertia when it moves to the end. Under the action of the stop bar 14 and the movable flap 17, it is stably inserted into the mud. As the slurry is filled, the feed pipe 1 can be pulled outwards. The above process is repeated to complete the filling of the geological fracture. When the grouting is stopped, the movable plate 6 is on the first elastic support member. 8 returns to its initial position, and the movable plate 6 pulls the outlet pipe 11 back into the feed pipe 1 through the arranged longitudinal rods 9 and the movable rods 10, and the movable flap 17 is embedded in the receiving groove 20; the device can automatically adjust the telescopic state according to the grouting process. On the one hand, there is no need to increase the internal structure by expanding the diameter of the feed pipe 1, so as to adapt to geological cracks of different widths and improve the applicability of the device. On the other hand, multiple metal strips 23 can be added to the slurry in sequence during grouting, which can enhance the structural strength of the slurry after solidification and avoid subsequent cracking.
