DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. In the case of no conflict, the embodiments in the application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0026] Please refer to Figure 1 and 2 The utility model provides a kind of grouting device for coal mine water disaster prevention, comprising:

[0027] Support 100, grouting pipe 101 is installed on it, grouting pipe 101 has feed inlet and discharge outlet on it;

[0028] Push frame structure 200, including at least one movable block 201 being arranged on the outer wall of grouting pipe 101 and being movable along axial direction, convex rod 202 being arranged along radial direction is inserted on movable block 201, push plate 203 is movably sleeved on convex rod 202, specifically, when push plate 203 is in initial state, convex rod 202 is completely located inside movable block 201 and push plate 203.

[0029] The utility model drives movable block 201 to move to corresponding position, i.e. between discharge outlet and blocking object, and then drives push plate 203 to move along radial direction to push away blocking object, to avoid the problem that grouting quality and efficiency are affected due to grouting channel wall collapse leading to grouting mouth being blocked, by movable block 201 on the surface of grouting pipe 101, after partial discharge outlet of grouting pipe 101 is blocked (whether discharge outlet is blocked can be judged by sensor arranged at discharge outlet, sensor only needs to judge whether slurry flows out at discharge outlet, and specific sensor model commonly seen in market can be used).

[0030] In an embodiment, please refer to Figure 1 and Figure 2 Movable block 201 is arranged on guide rod 204 arranged along axial direction, top end of guide rod 204 is connected with sleeve ring 205, sleeve ring 205 is arranged on support 100 and is rotationally connected with grouting pipe 101.

[0031] Specifically, tooth groove can be arranged on the outer wall of sleeve ring 205, and is driven by engaging with a gear driven by motor.

[0032] In this embodiment, sleeve ring 205 is arranged, which can drive guide rod 204 to rotate by sleeve ring 205 according to the position of blocked discharge outlet, so that push plate 203 moves to the required working position, and then anti-blocking operation can be realized by installing a push plate 203.

[0033] It should be noted that the present embodiment is directed to the technical solution of arranging only a single push plate 203, and of course, the number of discharge ports arranged along the circumference of the grouting pipe 101 can also be arranged.

[0034] In an embodiment, referring to Figure 3 , the movable block 201 is provided with a gas cylinder 206 arranged obliquely along the upper edge, and the piston rod end of the gas cylinder 206 is hinged to the push plate 203.

[0035] In the present embodiment, when the movable block 201 is moved axially to the desired working position of the discharge port, the push plate 203 is driven by the gas cylinder 206 to move radially away from the grouting pipe 101, pushing the block away from the discharge port, completing the work, and avoiding the problem that the discharge port cannot discharge grout or the discharge speed is reduced due to blockage.

[0036] In an embodiment, referring to Figures 1-4 , the push plate 203 is in an arc-shaped structure. In the present embodiment, the shape of the push plate 203 can be adapted to the shape of the grouting channel.

[0037] Preferably, the arc-shaped push plate 203 is arranged concentrically with the grouting pipe 101.

[0038] In an embodiment, the lower edge of the push plate 203 is in a beveled structure. In the present embodiment, the push plate 203 can be more easily extended between the block and the discharge port of the grouting pipe 101, thereby achieving the effect of pushing the block away from the discharge port.

[0039] In an embodiment, referring to Figure 2 , the guide rod 204 is provided with a driving gas cylinder 207 for driving the movable block 201 to move axially.

[0040] In the present embodiment, the movable block 201 is driven by the driving gas cylinder 207 to move along the guide rod 204 until the movable block 201 moves between the discharge port and the block, and the gas cylinder can provide reliable propulsion force for the movable block 201, so that the movable block 201 can break through the resistance of the block and smoothly separate the block, and then cooperate with the push plate 203 to push the block away.

[0041] In an embodiment, referring to Figure 1 and Figure 2 , the base 300 is further provided on the support 100, and the base 300 is provided with radially arranged and movable insertion rods 301.

[0042] Specifically, the insertion rod 301 is provided with at least two, and the insertion rod 301 can be controlled to move radially by a gas cylinder arranged in the base 300.

[0043] The embodiment is configured in this way. After the grouting pipe 101 is placed into the grouting channel, the insertion rod 301 is driven to move radially and is inserted into the grouting channel wall, so that the grouting pipe 101 is stabilized, and a gap is formed between the outer wall of the grouting pipe 101 and the grouting channel wall, thereby ensuring the smooth progress of the grouting operation.

[0044] In an embodiment, referring to Figure 3 The lower edge of the movable block 201 is provided with a reinforcing rod 208 arranged in the radial direction, and the reinforcing rod 208 is in sliding fit with the push plate 203.

[0045] The embodiment is configured in this way. When the push plate 203 is pushed in the radial direction, the push plate 203 is simultaneously slid along the reinforcing rod 208, so that the posture stability of the push plate 203 during movement is improved, and the risk of deviation due to excessive resistance is avoided, thereby improving the ability to solve the problem of the discharge opening being blocked.

[0046] In an embodiment, referring to Figure 4 The movable block 201 is provided with a dredging rod 209 penetrating therethrough, and the end of the dredging rod 209 is provided with a tooth groove. The push plate 203 is provided with a movable rod 210, the end of the movable rod 210 is provided with a tooth groove, and the movable rod 210 is in transmission connection with the dredging rod 209 through a gear 211.

[0047] Specifically, the diameter of the dredging rod 209 is smaller than the diameter of the discharge opening, and the front section (i.e., the section extending into the discharge opening) is made of a ductile material, such as hard rubber or the like, and the rear section is made of a hard material, such as aluminum alloy or the like.

[0048] The embodiment is configured in this way. When the push plate 23 is controlled to move radially and push away the blocking object, the movable rod 210 is driven to move, the movable rod 210 drives the dredging rod 209 to move in the direction close to the grouting pipe 101 through the gear 211. Since the position of the feeding opening is fixed, and the operation range of the push plate 203 is regional, the position of the push plate 203 can be controlled to make the dredging rod 209 face the discharge opening. Therefore, the dredging rod 209 can perform dredging operation on the discharge opening synchronously during the pushing process of the push plate 203, so that the problem of reducing the grouting efficiency due to the blocking object extending into the discharge opening in the early stage is avoided.

[0049] In an embodiment, the end of the dredging rod 209 close to the grouting pipe 101 is in a pointed structure. The embodiment is configured in this way, so that the movement ability of the dredging rod 209 during dredging of the discharge opening is improved, and the dredging quality is improved.
