[0023] When implementing: Figure 1-5 As shown, a coal mine paste filling end plugging support comprises a base 1, a lower baffle 2 and an upper baffle 3: the lower baffle 2 is arranged on the side of the base 1, the upper end of the lower baffle 2 is arranged on the upper end of the lower baffle 3, and the side of the lower baffle 2 is arranged with a connecting structure 23;

[0024] The connection structure 23 includes a connection block 5, a connection bolt 6 and a nut 9. The connection block 5 is disposed on the side of the lower baffle 2, the connection bolt 6 is disposed on the side of the connection block 5, and the nut 9 is disposed on the surface of the connection bolt 6.

[0025] When the device is in use, the brackets are first placed side by side and fitted together. At this time, the connecting bolts 6 are inserted into the interior of the connecting block 5, and then the nuts 9 are screwed onto the surface of the connecting bolts 6 to continue fixing the connecting bolts 6. In this way, the brackets are connected and fixed, so that the brackets fit more closely.

[0026] The connecting bolt 6 passes through the connecting block 5, the nut 9 is threadedly connected to the connecting bolt 6, and a mounting plate 4 is provided on the side of the base 1;

[0027] When the device is in use, after the bracket is connected and fixed, the bracket is then fixed by the mounting plate 4 to fix the bracket at the end of the paste filling to prevent the bracket from sliding and causing loss of the blocking effect.

[0028] A lifting jack 8 is provided on the side of the lower baffle 2, the upper end of the lifting jack 8 is connected to the upper baffle 3, and a supporting jack 7 is provided on the upper end of the base 1;

[0030] A fixing block 10 is disposed at the upper end of the base 1, and a fixing cover 12 is disposed at the upper end of the fixing block 10;

[0031] A limit rod 11 is disposed at the upper end of the fixing block 10, and a fixing bolt 13 is disposed at the upper end of the fixing cover 12, and the fixing bolt 13 is threadedly connected to the fixing block 10;

[0032] When the device is in use, the limiting rod 11 is first placed on the surface of the fixing block 10, and then the fixing cover 12 is covered on the surface of the fixing block 10 so that the fixing cover 12 and the limiting rod 11 are fitted together, and then the fixing bolt 13 is screwed into the inside of the fixing block 10 to fix the limiting rod 11, so that the limiting rod 11 can limit the multiple brackets to prevent the brackets from being misaligned and causing gaps between the brackets.

[0033] A side plate 14 is provided on the side of the lower baffle plate 2, a leakage hole 16 is provided inside the side plate 14, and the upper baffle plate 3 is slidably connected to the side plate 14;

When the slurry passes through the brackets, the slurry on the top is absorbed by the adsorption strip 17, and the slurry on the bottom directly enters the inner bottom of the side 14 and flows to the leakage hole 16. When the adsorption strip 17 absorbs too much, the slurry is guided to the lower end of the side plate 14, and the slurry passes through the leakage hole 16 into the interior of the shell 22, so that the sponge block 19 absorbs the slurry. At this time, the weight of the sponge block 19 increases, pressing downward, so that the sponge block 19 presses the button 21, and the prompt light 18 emits a light to remind the staff, so that the staff can quickly find the leakage and handle and maintain the leakage of the device.

[0037] When the utility model is in use, the device is first placed in the position where it needs to be blocked, the bracket is fixed and installed through the mounting plate 4, and then the lower baffle plate 2 is supported by the supporting jack 7 to make the lower baffle plate 2 more stable, and multiple brackets are placed in a close relationship, the connecting bolts 6 are inserted into the interior of the connecting block 5, and then the nuts 9 are screwed onto the surface of the connecting bolts 6 to connect the multiple brackets, and the bottom of the end is completely blocked, the adsorption strip 17 is inserted into the interior of the adsorption groove 15, and then the lifting jack 8 is opened to extend the upper baffle plate 3 so that the upper baffle plate 3 blocks the top of the end, and then the limiting rod 11 is placed on the surface of the fixing block 10, and then the fixing cover 12 is covered on the surface of the fixing block 10 so that the fixing cover 12 is in a close relationship with the limiting rod 11, and the fixing bolts 13 are screwed into the interior of the fixing block 10 to fix the limiting rod 11, so that the limiting rod 11 limits the bracket to prevent the bracket from being misaligned and causing gaps between the brackets.
