Clamp lifting tool used for clamping steel plates in uniform thickness manner

Abstract

The invention relates to a clamp type steel plate lifting tool and in particular relates to a clamp lifting tool which can realize clamping of steel plates in uniform thickness manner. The clamp type steel plate lifting tool comprises two connecting rods, clamp arms, a guide plate and a positioning plate, the upper ends of the two connecting rods are connected by virtue of a pin shaft, the lower ends of the two connecting rods are connected with the upper ends of two groups of clamp arms respectively by virtue of a pin shaft, the two groups of clamp arms are oppositely placed left and right, the middle parts of the two groups of clamp arms are respectively connected with the guide plate by virtue of a pin shaft, an arc-shaped guide rail is respectively arranged at each of the left end and the right end of the positioning plate, a guide rail connecting rod sliding along the arc-shaped guide rail is arranged on each arc-shaped guide rail, each arc-shaped guide rail is connected with the lower parts of the two groups of clamp arms by virtue of pin shafts, and the positioning plate and the guide plate form a moving pair along a vertical direction. Compared with the prior art, the clamp type steel plate lifting tool has the advantages of simple structure, high integral rigidity and implementation of uniform-thickness clamping on steel plates or billet components with different sizes.

Description

technical field [0001] The invention relates to a clamp type steel plate spreader, in particular to a clamp spreader capable of clamping steel plates with equal thickness. [0002] Background technique [0003] The clamp-type steel plate spreader is a special tool for steel plants, ports, and wharfs to transfer steel plates in large quantities. It is an engineering tool developed by utilizing the principles of leverage, tribology and other mechanics. This kind of spreader has strong adaptability and has the characteristics of loading and unloading items freely without the cooperation of ground personnel. This kind of appliance has the functions and characteristics of the spreader and the clamp at the same time, and is a composite of the two. The working principle of this type of spreader is: when lifting with the same lifting force as the weight of the clamped part, the clamp arm forms a lever action to form a clamping force between the jaws and the clamped part. Due to fr...

Problems solved by technology

[0004] The structure of the current clamp-type steel plate spreader is mostly a hinged four-bar mechanism or a simple crank slider mechanism. Since it satisfies the movement law of the mechanism itself in principle, when the width of the clamped steel plate (clamp opening size) is different, The clamping thickness (the vertical distance between the top surface of the steel plate and the jaws) will also change accordingly, so equal thickness clamping cannot be achieved
