Medium is indirectly connected, can connection inside two elements.
As shown in Figures 1 to 3, a kind of deep basal pit draws a frame, comprising: vertical supporting device 2, on the vertical supporting device 2
End is equipped with cross-brace device 1, and 1 side of cross-brace device is equipped with steel wire 3, and described 3 one end of steel wire is mounted on lateral branch
On support arrangement 1, the other end be equipped with iron cone 4, between the vertical supporting device 2 and cross-brace device 1 junction be equipped with steel
Pipe diagonal brace 14,2 lower end of vertical supporting device are equipped with chassis 15, and vertical supporting device 2 is weldingly fixed on chassis 15, described
Chassis 15 is mounted on the base by expansion bolt 17, and described 1 one end of cross-brace device is equipped with depth V pulley 5, the other end is equipped with
U-shaped pulley 12, is equipped with pulley handle 11 on the U-shaped pulley 12, and steel wire 3 is mounted on deep V pulley 5, on U-shaped pulley 12, institute
The cross-brace device 1 for stating U-shaped 12 side of pulley is equipped with sleeve 10, is equipped with limit steel bar in the sleeve 10.
The cross-brace device 1 includes telescoping tube 7, steel pipe 6, and 7 one end of telescoping tube is equipped with steel pipe 6, on the telescoping tube 7
Equipped with flexible adjustment bolt 13.
The vertical supporting device 2 includes several vertical bars, and vertical bar both ends are equipped with ring flange 8, pass through ring flange between vertical bar
8, bolt 9 is connected and fixed.
The depth V pulley 5, U-shaped pulley 12 are mounted on cross-brace device 1 by pulley installation axle.
The iron bores 4 upper ends and is equipped with threaded hole, and iron is equipped in threaded hole and bores cap 16, iron, which is bored, is equipped with outer spiral shell on the outside of cap 16
Line, iron bore cap by being threadably mounted on iron cone 4, and iron cone 4 is bored cap 16 by iron and is mounted on steel wire 3.
When deep basal pit draws, chassis 15 is first fixed on ground using expansion bolt 17, keeps upright bar solid reliable, then root
Determine whether vertical steel pipe needs to increase by a section by ring flange or stretch with lateral steel pipe according to the height and extension elongation of vertical shaft fence
