Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 3, a formwork panel balanced lifting device includes an angle support block 1, a connecting rod 2, a tightening fixing mechanism, and a lifting mechanism; a first through groove 3 and a second through groove 4 are formed in the corner support block 1, the cross section of the connecting rod 2 is matched with the first through groove 3 and the second through groove 4, and the extending directions of the first through groove 3 and the second through groove 4 are perpendicular to each other; the cross section of the connecting rod 2 is I-shaped; the tightening and fixing mechanisms are respectively positioned on the side surfaces of the first through groove 3 and the second through groove 4; the tightening fixing mechanism is positioned on the side surface of the corner support block 1, corresponds to the first through groove 3 and the second through groove 4 in position, and comprises a screw rod 5 and a hand wheel 6; the screw rod 5 penetrates through a threaded hole in the corner support block 1 and is respectively contacted with the side wall of the connecting rod 2 in the first through groove 3 and the second through groove 4, the hand wheel 6 is coaxially connected with one end, far away from the connecting rod 2, of the screw rod 5, the hand wheel 6 is used for facilitating the manual screwing of an operator, and the screw rod 5 is used for jacking or loosening the connecting rod 2 to realize the fastening and the separation of the connecting rod 2 and the corner support block 1; lifting mechanism is located angle support piece 1, lifting mechanism includes pneumatic cylinder 7 and lifting hook 10, lifting hook 10 passes through the detachable connection of the piston rod of wire rope 9 with pneumatic cylinder 7, lifting hook 10 is used for catching on the rings on the die carrier board, can use the wire rope 9 of different length according to actual demand.
