Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a convenient and rapid sealing device for coal mine roadways. Background Technology

[0002] In the field of coal mine safety production, roadway sealing is a crucial step in gas extraction, fire prevention and extinguishing, and dust control. Existing coal mine roadway sealing processes mostly employ manual grouting or traditional sealing equipment, which suffers from low sealing efficiency, poor sealing performance, and high labor intensity. Traditional sealing devices typically rely on split-type grouting pumps and manual pipe insertion. In the narrow and complex environment of underground roadways, equipment transportation is difficult, and pipeline connections are cumbersome. A single sealing operation can take several hours, severely hindering the progress of mining operations. Therefore, this utility model proposes a convenient and rapid coal mine roadway sealing device. Utility Model Content

[0007] Optionally, a pull rod is installed at the end of the connecting rod away from the sealing plate.

[0008] Optionally, the outer side of the base plate has multiple sets of mounting slots arranged in a ring array, and multiple sets of insert plates are respectively arranged in the multiple sets of mounting slots. A rotating shaft is rotatably connected to the insert plate, and the rotating shaft is fixedly connected to the mounting slot. An offset plate is installed at one end of the insert plate.

[0009] Optionally, the fastening assembly includes a fixed ring fixedly connected to the side of the base plate away from the wall, a movable ring threadedly connected to the outside of the fixed ring, and a compression ring installed on the outer ring of the movable ring, the compression ring having a right-angled trapezoidal cross-section.

[0029] Example

[0030] like Figure 1 and Figure 2 As shown, the present invention proposes a convenient coal mine roadway rapid sealing device, which includes a base plate 1, and a through hole 11 is provided in the base plate 1 to facilitate the injection of sealing material into the hole through the through hole 11.

[0031] Furthermore, the aforementioned sealing device includes a sealing mechanism 2 installed on the side of the base plate 1 away from the wall, which is used for sealing the hole. The sealing mechanism 2 includes a fixed cylinder 21 fixedly connected to the side of the base plate 1 away from the wall, into which cement mortar is injected to fill the hole in the coal mine roadway. A mounting cover 22 is threadedly connected to the end of the fixed cylinder 21 away from the base plate 1, and the mounting cover 22 moves along the length of the fixed cylinder 21 when rotated. Multiple sets of arc-shaped plates 23 are fixedly connected to the side of the mounting cover 22 away from the fixed cylinder 21, and threaded sleeves 24 are threadedly connected to the outer side of the multiple sets of arc-shaped plates 23. A connecting rod 25 is provided through the mounting cover 22, and the connecting rod 25 is located between the multiple sets of arc-shaped plates 23. After the threaded sleeve 24 is threadedly connected to the outer side of the multiple sets of arc-shaped plates 23, the arc-shaped plates 23 clamp the connecting rod 25, fixing the relative position of the mounting cover 22 and the connecting rod 25. A rubber pad is installed on the side of the arc-shaped plate 23 near the connecting rod 25 to increase friction and prevent the connecting rod 25 from sliding after the arc-shaped plate 23 clamps the connecting rod 25. A sealing plate 26 is rotatably connected to the end of the connecting rod 25 near the base plate 1. The sealing plate 26 blocks the cement mortar in the hole after being inserted into the fixed cylinder 21. A pull rod 27 is installed on the end of the connecting rod 25 away from the sealing plate 26. The pull rod 27 facilitates the movement of the sealing plate 26.

[0032] For details, please refer to Figure 1 and Figure 3 The sealing device further includes multiple sets of insert plates 3 rotatably connected to the side of the base plate 1. The insert plates 3 are used to fix the base plate 1 to the wall. Multiple sets of mounting slots 12 arranged in a circular array are provided on the outer side of the base plate 1. The multiple sets of insert plates 3 are respectively disposed in the multiple sets of mounting slots 12. A rotating shaft 31 is rotatably connected to each insert plate 3, and the rotating shaft 31 is fixedly connected to the mounting slot 12. After the insert plate 3 is inserted into the wall, it fixes the base plate 1 to the wall. An offset plate 32 is installed at one end of the insert plate 3. When the offset plate 32 deflects, it drives the insert plate 3 to deflect synchronously.

[0033] Furthermore, the aforementioned sealing device also includes a fastening assembly 4 disposed on the side of the base plate 1 away from the wall. The fastening assembly 4 is used to synchronously drive the multiple sets of insert plates 3 to deflect. The fastening assembly 4 includes a fixed ring 41 fixedly connected to the side of the base plate 1 away from the wall, and the position of the fixed ring 41 is fixed. A movable ring 42 is threadedly connected to the outside of the fixed ring 41, and the movable ring 42 moves along its own length direction when rotating. A compression ring 43 is installed on the outer ring of the movable ring 42. The compression ring 43 has a right-angled trapezoidal cross-section. The movable ring 42 and the compression ring 43 move synchronously, and at the same time, the compression ring 43 compresses the offset plate 32 to cause offset. Multiple sets of operating rods 44 are installed on the outer ring of the compression ring 43. The operating rods 44 are set to facilitate the rotation of the compression ring 43 and the movable ring 42. A baffle 45 is installed on the end of the fixed ring 41 away from the base plate 1. The baffle 45 is fixedly connected to the fixed cylinder 21. The baffle 45 is set to prevent dust and impurities from entering between the fixed ring 41 and the fixed cylinder 21.

[0034] In this embodiment, the worker first holds the insert plate 3 with their hand, so that the end of the offset plate 32 away from the insert plate 3 is in contact with the moving ring 42 and the compression ring 43. The insert plate 3 is then inserted into the wall until the base plate 1 is in contact with the wall. At this time, the hole position corresponds to the through hole 11. The compression ring 43 is rotated by the operating rod 44, which drives the moving ring 42 to be threadedly connected to the fixed ring 41. When the moving ring 42 moves, it drives the compression ring 43 to move synchronously. After the compression ring 43 moves, it drives the offset plate 32 to shift, thereby driving the insert plate 3 to move synchronously. The insert plate 3 tilts in the wall, improving the firmness of the base plate 1 after it is fixed. Mortar is injected into the hole through the fixed cylinder 21 until the hole is full of mortar, and some mortar remains in the fixed cylinder 21. Then, the sealing plate 26 is slidably connected to the fixed cylinder 21, with one side of the sealing plate 26 in contact with the mortar in the fixed cylinder 21. The mounting cover 22 is then threadedly connected to one end of the fixed cylinder 21. Rotate the threaded sleeve 24. After the threaded sleeve 24 is tightened, it will cause the arc plate 23 to press the connecting rod 25, thereby fixing the position of the sealing plate 26.

[0035] After the mortar solidifies, it may adhere to the fixing cylinder 21 and the sealing plate 26. At this point, rotating the mounting cover 22, which is threadedly connected to the fixing cylinder 21, moves the cover away from the base plate 1. Simultaneously, the arc-shaped plate 23 drives the connecting rod 25 to move, moving the sealing plate 26 away from the solidified mortar. The operating rod 44 is then used to reverse the pressure ring 43, resetting it and eliminating the pressure of the insert plate 3 on the wall. Rotating the mounting cover 22 again moves the sealing plate 26 closer to the base plate 1. The reaction force then moves the base plate 1 and the fixing cylinder 21 away from the wall, facilitating the removal and reuse of the sealing device.

[0036] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
