Preferably, the cross section of the foot stool is a trapezoidal cross section, and the foot stool having such a cross section has higher mechanical strength, so that the top beam and the bottom beam can be stably supported.

Preferably, a positioning pull rope is arranged on the connecting portion and used for finely adjusting the relative position of the whole rapid lifting device relative to the cylinder.

Preferably, the positioning cord is a steel cord, and the use of such a steel cord can improve the structural strength of the positioning cord 70, thereby further ensuring the safety of the operation of the quick lifting device.

Preferably, the area of the top surface of the foot seat is one third of the area of the bottom surface, and the design is helpful for increasing the stability of the foot seat.

Preferably, the bottom beam has a rectangular cross-sectional shape. Further preferably, the cross-sectional shape of the top beam is also rectangular. Still preferably, the cross-sectional shape of the connecting portion is also rectangular.

The utility model discloses has following technological effect:

the technical scheme of the utility model in, because during hoist and mount, the barrel transversely placed, consequently than erectting among the prior art and place the hoist and mount, reduced hoist and mount operation space, the factory building height reduces, and the factory building construction cost can compress. Because the telescopic stay bar is fixed in the cylinder body, the hoisting is safe and reliable, and the cylinder body is hardly deformed.

Detailed Description

The following further describes embodiments of the present invention with reference to the accompanying drawings:

referring to fig. 1-2, the utility model provides a large-scale thin wall barrel fast lifting device 100 includes:

a U-shaped hanging body 20 composed of a foot seat 22, a bottom beam 24 arranged on the foot seat 22, and a top beam 26 arranged above the bottom beam 24 and connected with the bottom beam 24 by a connecting part 28;

a lifting ring 30 fixed to the top beam 26;

a sling 40 fixed to the hoist ring 30; and

and a telescopic stay bar 50 fixed to the bottom end of the sling 40.
