The utility model discloses an aluminum formwork climbing frame supporting device which comprises an outer
pipe, a driving seat arranged at one end of the outer
pipe, a first end of a screw rod penetrating through the driving seat and extending into the outer
pipe, a guide groove formed in the inner wall of the outer pipe, a positioning pin arranged at the first end of the screw rod, and a first
bevel gear rotationally arranged in the driving seat, the second
bevel gear is rotationally arranged in the driving seat and is meshed with the first
bevel gear, and the driving piece is coaxially connected with the second bevel gear; the first bevel gear directly drives the screw rod through threaded connection, rotary motion is accurately converted into
axial thrust through matching of the guide groove and the positioning pin, self-locking performance is achieved, safety is improved, the second bevel gear is driven to rotate through the driving piece, the second bevel gear drives the first bevel gear to rotate, the
power transmission direction is changed, and the
power transmission efficiency is improved. And when the two ends of the supporting device are stressed, the supporting distance can still be conveniently adjusted, and the construction efficiency is improved.
