The invention relates to a clamping device for increasing the hoisting size of a plate. The clamping device comprises a hanging beam; a hook matched with a crane is arranged at the top of the hanging beam; two rows of clamping hooks are symmetrically arranged on two sides of the hanging beam; clamping rings matched with the clamping hooks are arranged at ends of steel wire ropes; claw hooks matched with the plate are arranged at the other ends of the steel wire ropes; the claw hooks comprise hooked clamping parts; U-shaped grooves are formed in the connection ends of the clamping parts; connecting plates are arranged in the U-shaped grooves through rotating shafts; fixed holes matched with the steel wire ropes are formed in ends of the connecting plates; the other ends of the connection plates extend into the clamping parts. The claw hooks are arranged at the end parts of the steel wire ropes, the clamping parts of the claw hooks are used for clamping the plate in the moving process of the plate, and the connection plates extend into the ends in the clamping parts to clamp the plate, so that the plate is fixed, the condition that the plate falls off from a hoisting device in the moving process of the plate is avoided, plates of different sizes are hoisted by mounting the steel wire ropes on the claw hooks in different positions, and the size ranges of hoisted plates are increased.
