Fig. 1-3 is please referred to, the present invention provides a kind of scheme: small mine pillar, including sleeve 1, and the bottom end of sleeve 1 is solid
It is connected to bottom plate 9, inserted with the first bolt 3 at left and right sides of the upper surface of bottom plate 9, the first bolt 3 runs through bottom plate 9, bottom plate 9 and the
One bolt, 3 screw thread is connected, and the bottom end of the first bolt 3 is equipped with pedestal 4, and pedestal 4 is rotatedly connected by bearing 5 with the first bolt 3, axis
The inner ring and the first bolt 3 for holding 5 are fixedly linked, and outer ring and the pedestal 4 of bearing 5 are fixedly linked, at left and right sides of the lower surface of bottom plate 9
It is connected with riser 6, slide bar 8 is connected between riser 6, the outer wall movable sleeve of slide bar 8 is connected to idler wheel 7, between idler wheel 7 and riser 6
Gap cooperation, the first bolt 3 is rotated counterclockwise, and the first bolt 3 rotates counterclockwise so that pedestal 4 rises, and pedestal 4, which rises to, to be made
After idler wheel 7 and ground offset, stop operating the first bolt 3, at this moment small mine pillar can be shifted onto what needs supported
Below mine hole, the first bolt 3 is being rotated clockwise, stop operating the first bolt 3 after so that pedestal 4 and ground is offseted, sleeve 1
Top is inserted with loop bar 10, loop bar 10 and 1 clearance fit of sleeve, and the outer wall top left and right sides of sleeve 1 is inserted with the second spiral shell
Bolt 12, the second bolt 12 offset through a part of sleeve 1 with loop bar 10, and the second bolt 12 is connected with 1 screw thread of sleeve, loop bar
Multiple grooves 11 are provided at left and right sides of 10 pairs of outer wall bottom end, upper and lower ends are connected with cross at left and right sides of the outer wall of sleeve 1
Bar 13, the left side of cross bar 13 are connected with vertical bar 14, rotate counterclockwise the second bolt 12, rotating counterclockwise for the second bolt 12 can
So as to generate gap between the second bolt 12 and groove 11, second is stopped operating until groove 11 and the second bolt 12 are kept completely separate
Then bolt 12 is moving up loop bar 10 according to the height in mine hole, the loop bar 10 made offsets with mine hole, then stops upward
Mobile loop bar 10, is rotating clockwise the second bolt 12, so that the second bolt 12 is offseted with groove 11, that is, which can support required branch
The mine hole of support, the top of loop bar 10 are connected with the second rubber pad 15, and the second rubber pad 15 is made of General Purpose Rubber material, under room temperature
There is certain toughness, surface is more coarse, is connected with the first convex block 16, the first convex block at left and right sides of the outer wall top of loop bar 10
16 left side is equipped with transverse slat 17, and transverse slat 17 is rotatedly connected by the first pin shaft 18 with the first convex block 16, and the lower surface of transverse slat 17 is left
Side is connected with the second convex block 19, and the bottom end of the second convex block 19 is equipped with bull stick 20, and bull stick 20 passes through the second pin shaft 21 and the second convex block
19 are rotatedly connected, and the bottom end of bull stick 20 is connected with riser 22, and the left-hand face of riser 22 is inserted with third bolt 25, third bolt
25 are connected through riser 22 with 10 screw thread of loop bar, and transverse slat 17 is rotated, and transverse slat 17 can be rotated centered on the first pin shaft 18, bull stick
20 can be rotated centered on the second pin shaft 21, and the top of transverse slat 17 and loop bar 10 is made to rotate clockwise third bolt 25 simultaneously,
So that offseting between third bolt 25 and riser 22, the bearing area of small mine pillar, the top of transverse slat 17 can be increased
