The vertical plate clamp is a tool for clamping, fastening and hoisting. The tool has been widely used in major domestic steel mills, and the Pangang cold rolling mill is equipped with such a vertical coil clamp device. At present, the application of the pair of jaws is automatic to the neutral roll clamp device. The electric horizontal winding clamp device is composed of a crane hook hanging portion, a respective link portion for opening and closing the caliper arm, a caliper arm opening and closing driving portion, and a caliper arm portion.
The vertical plate clamp is used by hanging the clamp on the hook of the crane, opening and closing the clamp arm under zero load, and grasping and transporting the steel. The working sequence of the caliper arm is: opening and closing motor, a driving shaft, a screw pair, a connecting rod, a caliper arm opening and closing (parallel movement).
At the same time, in the process of steel plate handling, the vertical plate clamp is also effective to ensure its safety - a locking device that cannot open the caliper arm is provided. At the same time, a clamp minimum closing limit switch is installed on the upper part of the hanging beam or the upper part of the opening and closing drive device to prevent motor overload and minimum closing detection of the clamp arm. A clamp maximum closing limit switch is installed in the lower part of the hanging beam or in the lower part of the opening and closing drive device to prevent motor overload and maximum closing detection of the clamp arm.
