The specific embodiment

Can be known by Fig. 1 Fig. 2: the utility model has lift telescopic mechanism, and it forms a framework by preceding transverse tube 9, rear cross-tube 26 and two side pipes 10, is provided with oscillating cylinder 18 in it, changes cylinder 23 and chucking cylinder 13;

Oscillating cylinder 18 is located on the bottom plate 20, and fixing by oscillating cylinder seat axle 19, piston rod is connected with rotary disk basement 21 through swinging axle 12, and the strong plate 11 in back is located on the rear cross-tube 26, and cover plate 15 is located at the top of oscillating cylinder 18; Changeing cylinder 23 fixes on the rotary disk basement 21 with commentaries on classics cylinder axle 2 through changeing cylinder seat 1; Also be provided with rope sheave seat 17, rope sheave 16 on the rotary disk basement 21; The piston rod that changes cylinder 23 is provided with commentaries on classics cylinder card 22 and blocks wire rope 5; Wire rope 5 is walked around rope sheave 16, and through the groove on rotating disk 8 peripheries, the two ends of wire rope 5 are fixing with two rope fixtures 6 that are located at above the rotating disk 8;

Chucking cylinder 13 is located on the rotating disk 8; On rotating disk 8, also be provided with two and clamp connecting plates 27, two clamp shafts 28, two chucking bodies 14 and two supporting plates 3; Chucking cylinder 13 is connected with two chucking bodies 14; Rotating disk 8 is located on the rotary disk basement 21 through rotary disk basement axle 4, and rotary disk basement 21 carries out the position along preceding floor 24 with floor 25, back and moves under the effect of oscillating cylinder 18, pressing plate 29 and the upwards play of side guide 30 control rotary disk basements 21 when moving.

Use the utility model; It is connected with lift telescopic mechanism and is installed on the development machine; Hydraulic power comes from development machine, and steel I-beam is placed on two supporting plates 3, starts the bottom that chucking cylinder 13 makes two chucking body 14 chucking steel I-beams; The position of looking beam station leg starts oscillating cylinder 18 and changes cylinder 23, and the adjustment i iron is placed on the position on the leg of beam station.

The move left and right of oscillating cylinder 18 control rotating disks 8, when piston rod was regained, rotary disk basement 21 was moved to the left along preceding floor 24 and floor 25, back, and the i iron that is placed on accordingly on the supporting plate 3 also is moved to the left, and vice versa.

Change cylinder 23 and be adjustment i iron level angle, block wire rope 5 when changeing cylinder card 22, when piston rod back and forth moved, rotating disk 8 horizontally rotated will on rotary disk basement 21, doing the traction of wire rope 5 under, and i iron is also adjusted a level angle accordingly.

The withdrawal of chucking cylinder 13 piston rods and stretching out makes chucking body 14 chuckings or unclamps i iron.
