[0002] In the welding process of steel structures, thin steel plates are often used. The lifting of steel plates requires the use of spreaders. The current spreader is a cast iron block with a U-shaped groove on it. When placing the slot of the spreader directly on the edge of the steel plate, and then lift it up, although the structure of the spreader is simple, since the spreader is only inserted on the side of the steel plate, the size of the steel plate and the U-shaped groove must match. If the size of the steel plate and the tank wall are not suitable, there may be a risk of slippage of the steel plate and the spreader when lifting the steel plate, especially when the steel plate is relatively thin, the steel plate is prone to deformation, and the risk of slipping is greater

Embodiment Construction
[0026] The present invention will be described in further detail below through specific examples.
[0027] Such as Figures 1 to 4 As shown, a thin plate lifting spreader includes a fixture body 1 with a U-shaped groove, the opening of the U-shaped groove faces the horizontal side, and the top of the fixture body 1 is provided with a hanging plate part 2 for easy hoisting. The hanging plate A circular hoisting hole 21 is provided on the part 2, an upper protrusion 3 is provided on the upper edge of the U-shaped groove, and two screw holes are arranged on the lower edge of the U-shaped groove, and a lock is installed on the internal thread of the screw hole. Tightening studs 4, the two locking studs 4 and the upper protrusion 3 jointly clamp the thin plate, the side blind end of the U-shaped groove is provided with a plastic backing plate 6, and a locking screw near the side blind end The end of the column 4 is provided with an anti-slip structure.

The invention discloses a lifting tool for lifting a sheet. The lifting tool comprises a clamp body with a U-shaped groove. An opening of the U-shaped groove faces the horizontal side face. The top of the clamp body is provided with a plate lifting part facilitating lifting. A round lifting hole is formed in the plate lifting part. An upper protrusion is arranged on the upper edge of the U-shaped groove. Two screw holes are formed in the lower edge of the U-shaped groove. Locking studs are installed in the screw holes in a threaded manner, and the sheet is commonly clamped by the two locking studs and the upper protrusion. A plastic cushion plate is arranged at the blind end of the side portion of the U-shaped groove, and an anti-skid structure is arranged at the end portion of the locking stud close to the blind end of the side portion. The lifting tool can better lift a steel plate, slipping of the steel plate is avoided, the same lifting tool can be suitable for fixing steel plates with different thicknesses, and the lifting tool is particularly suitable for lifting thin steel plates.
Description
technical field [0001] The invention relates to a lifting spreader, in particular to a steel plate lifting spreader. Background technique [0002] In the welding process of steel structures, thin steel plates are often used. The lifting of steel plates requires the use of spreaders. The current spreader is a cast iron block with a U-shaped groove on it. When placing the slot of the spreader directly on the edge of the steel plate, and then lift it up, although the structure of the spreader is simple, since the spreader is only inserted on the side of the steel plate, the size of the steel plate and the U-shaped groove must match. If the size of the steel plate and the tank wall are not suitable, the steel plate and the spreader may have the risk of slipping when lifting the steel plate, especially when the steel plate is relatively thin, the steel plate is prone to deformation, and the risk of slipping is greater.
