In the U-lag of corresponding adjusting screw rod mounting base, and screw in the adjusting nut in U-lag, by positive and negative rotation adjusting nut,
And then drive adjacent two sides oil cylinder fixing base opposite or go in the same direction, achieve the purpose that adjust oil cylinder spacing.
8. interior arch according to claim 7 underpins boom device, which is characterized in that each column includes multistage
Unit column, multistage unit column are successively installed, whole to be arranged along the vertical direction, and the vertical adjusting apparatus includes being located at lower section
The upper inside wall of unit column is welded with the inner sleeve of 30-500mm long, has and inner sleeve spiral shell positioned at the lower weld of upper segment unit column
The screw rod that line matches, screw rod are made of hollow steel tube, and the lower section of screw rod is screwed into the inner sleeve of lower segment unit column, by artificial
The handle on rotary screw top, screw rod forms slope of thread movement with the inner sleeve being welded on inside lower segment unit column, due to spiral shell
Bar and inner sleeve are all separately fixed on lower segment unit column and upper segment unit column, and lower segment unit column is moved down by ground institute
It limits and then is converted to segment unit column vertically unidirectional shift movement, reach the adjustment needs for adapting to vertical dimension；Lowermost
Unit column bottom is equipped with support, and holder top and column bottom are sphere-contact.
