DETAILED DESCRIPTION

[0016] Please refer to Figures 1-4The utility model provides following technical scheme: including support pole main part 1 and extension pole 11, support pole main part 1 one side fixedly connected with the fender 2, the fender 2 one side fixedly connected with the lamination board 21 that is pasted with extension pole 11, the fender 2 and lamination board 21 are distributed and are equipped with the connecting groove 22 and the let -out groove 23 for the bolt is let -out, two adjacent support pole main part 1 are connected through the fixed plate 3, the fixed plate 3 is slidably connected with the slide bar 31, and the slide bar 31 outer wall is penetrated with the limiting plate 32, and the two limiting plate 32 are fixedly connected with the vertical board 33, and the vertical board 33 and support pole main part 1 are clampedly connected with a plurality of blocking plate 34, and the blocking plate 34 is connected through the plug -in rod 35, and support pole main part 1 one side detachably connected with the protection frame 4, and the protection frame 4 one side is equipped with a plurality of side plate 41 corresponding with blocking plate 34, and the side plate 41 one side is fixedly connected with two support rods 42, and the vertical board 33 is equipped with let -out hole 331.

[0017] In the embodiment: the support rod body 1 is the carrier of the bearing device, and the mine tunnel is supported and reinforced by connecting the support rod body 1 and the extension rod 11 in the mine tunnel. In order to facilitate the movement of personnel in the mine tunnel and the like, the protective plate 2 and the fitting plate 21 installed on the support rod body 1 correspond to the support rod body 1 and the extension rod 11, respectively, are connected through the connecting groove 22 and the gap groove 23, and the lower limit hole 12 and the upper limit hole 13 are connected through the bolt. The rest of the upper limit hole 13 can be protected by the protective plate 2 and the fitting plate 21, and the bolt can be given a gap by the connecting groove 22 and the gap groove 23. After a long time, the upper limit hole 13 is blocked by soil and gravel, which affects its use. The support rod body 1 is generally erected on both sides of the inner wall of the mine tunnel, and the stones on the inner wall of the mine tunnel are prone to fall off, which affects the normal use of the mine tunnel. At this time, the support rod body 1 support can connect the spacing between them and the stability of the support rod body 1 through the fixed plate 3. The sliding rod 31 slidingly connected to the fixed plate 3 can penetrate the limiting plate 32. The upper and lower limiting plates 32 are connected and fixed through the vertical plate 33, so that the fixed plate 3 is wrapped and limited by the vertical plate 33. A plurality of blocking plates 34 are spliced between the support rod bodies 1, so that the soil and gravel falling off the inner wall of the mine tunnel can be blocked by the blocking plates 34. The blocking plates 34 support the soil and gravel to prevent them from directly falling into the mine tunnel and affecting the normal use of the mine tunnel. After the blocking plates 34 isolate the soil and gravel, when the soil and gravel have a large amount, the soil and gravel need to be cleaned. When the blocking plates 34 block a large amount of soil and gravel, the blocking plates 34 are subjected to a large pressure of the soil and gravel, which directly causes them to open, which can cause the soil and gravel to directly fall into the mine tunnel, affecting the use of the mine tunnel, and thus it is not convenient to clean the soil and gravel. At this time, the protective frame 4 can be connected to the two support rod bodies 1 to protect the outside of the blocking plate 34. The sliding rod 31 is slid upward out of the fixed plate 3 and the limiting plate 32, so that the limiting plate 32 opens the wrapping of the blocking plate 34. At this time, the side plate 41 installed on the protective frame 4 penetrates the gap hole 331 in the vertical plate 33 through the support rod 42 fixedly connected to one side of the side plate 41 and is connected to the blocking plate 34, so that the blocking plate 34 is supported by the support rod 42. At the same time, the blocking plate 34 is opened by the limiting plate 32 and the sliding rod 31, so that it can slide outward and be out of position with the blocking plate 34. At this time, the blocking plate 34 can be taken out from the plug rod 35 in turn, so that the soil and gravel supported by each blocking plate 34 can be discharged from top to bottom in turn, so that the device can clean the blocked soil and gravel while preventing the soil and gravel from affecting the surrounding environment, so as to facilitate the safe cleaning thereof.

[0018] The supporting rod body 1 and the extension rod 11 are provided with matched lower limiting holes 12 and upper limiting holes 13, and the lower limiting holes 12 and the upper limiting holes 13 are connected through a bolt; the lower limiting holes 12 and the upper limiting holes 13 are used for supporting and limiting the position of the extension rod 11 on the supporting rod body 1, so that after the bolt is connected between the lower limiting holes 12 and the upper limiting holes 13 of the supporting rod body 1 and the extension rod 11, the device can support the mine tunnel.

[0019] The fixed plate 3 is provided with a connecting hole 311 matched with the sliding rod 31, and the outer wall of the connecting hole 311 is fixedly connected with a rotating plate 312; the connecting hole 311 provided on the fixed plate 3 can be inserted and installed with the sliding rod 31, so that the sliding rod 31 can pass through the limiting plate 32 to support and limit the position of the vertical plate 33, and the blocking plate 34 is supported and limited on the supporting rod body 1 to be protected.

[0020] The blocking plate 34 is provided with an insertion hole 351 connected with the insertion rod 35, and one of the fixed plates 3 is provided with a sliding groove 341 matched with the limiting plate 32; the insertion hole 351 provided on the blocking plate 34 is used for installing the insertion rod 35, so that after the insertion rod 35 is connected with the insertion hole 351, the blocking plate 34 is spliced up and down to protect the soil and gravel, and the sliding groove 341 is used for enabling the limiting plate 32 at the bottom to pass through the sliding groove 341, so that the limiting plate 32 is aligned with the sliding rod 31 below and is inserted and limited by the sliding rod 31.

[0021] The side plate 41 is rotatably connected with a connecting rod 43, and the connecting rod 43 is threadedly connected with one side of the protection frame 4; the connecting rod 43 rotatably connected with the side plate 41 is used for connecting the side plate 41 with the protection frame 4 to fix the position of the supporting rod 42, so that after the vertical plate 33 is separated from the blocking plate 34, the blocking plate 34 can be temporarily supported by the supporting rod 42, and when the blocking plate 34 needs to be taken out in sequence, the connecting rod 43 can be separated from the protection frame 4, so that the blocking plate 34 can be removed.

[0022] The utility model discloses a working principle and use flow: through the support pole main part 1 and extension pole 11 are supported to the mine way, make a plurality of barrier plate 34 receive the connecting of plug -in rod 35, upper and lower splicing between support pole main part 1, make barrier plate 34 support soil broken stone, prevent its direct scattering to the mine way and influence the normal use of mine way, the slide bar 31 of fixed plate 3 sliding connection can penetrate the spacing plate 32 of one side fixed connection of vertical plate 33, make vertical plate 33 support barrier plate 34 rear side, when needing to clean barrier soil broken stone, through the protection frame 4 and butt joint to two support pole main part 1, the side plate 41 of protection frame 4 installs on this time through its one side fixed connection's support rod 42 through the let -go hole 331 of vertical plate 33 and butt joint to barrier plate 34 on this time, can through making side plate 41 and protection frame 4 one side separate from each other in proper order to take out barrier plate 34 from plug -in rod 35 in proper order, make the broken stone soil of each barrier plate 34 on support can be discharged from top to bottom in proper order, make the device can clean barrier soil broken stone, can prevent soil broken stone and produce the influence to the surrounding environment, so as to all to its safe cleaning.
