Hoisting and transport device extracting article from local high temperature area

Abstract

The hoisting and transport equipment includes transport tracks, transport frame, hoister on the frame, frame driving drag and manipulator, suspended under the frame. The manipulator of whole metal structure includes link arm and grab, the link arm is two planar four-link mechanisms and the grab includes arm with guide mechanism, grabbing hook and hook opening and closing mechanism comprising bent link rod, pull-push flexible shaft and electric cylinder. The equipment is provided with touch sensing mechanism, hook opening sensing mechanism and manipulator elevating limit sensing mechanism, with the electric devices for the sensing mechanisms being far away from the manipulator. The equipment is matched with PLC and can grab article in preset position precisely while sending signal.

Description

Technical field [0001] The invention belongs to a lifting and transporting machine, and relates to a mechanical device for grabbing, lifting and transporting workpieces from a local high temperature zone. Background technique [0002] Lifting and transporting devices commonly used in general factories, such as CD cranes, have no automatic grabbing function in terms of their hook structure. And some hooks with automatic grabbing function mostly use the gravity of the hook or the reaction force from the workpiece to trigger the opening and closing mechanism of the hook to realize automatic grabbing. Since this kind of machine itself does not provide a feedback signal of "whether the item is caught", the operator needs to judge whether the item (workpiece) is caught. The hook of some special cranes can provide a feedback signal of "whether the item is caught", but the sensor that collects the signal is installed near the hook opening and closing mechanism, which limits the use envir...

AI Technical Summary

Problems solved by technology

The hook of some special-purpose cranes can provide a feedback signal of "whether the object is caught". However, the sensor for collecting the signal is installed near the opening and closing mechanism of the hook, which limits the use environment of the hook. Used in environments with local high temperature or corrosive atmosphere

There are still some lifting and transporting devices with automatic detection function in the prior art, such as some equipment on the robot and automatic assembly line, some of which have complex structures and control, some require very accurate positioning of items, and some are reliable. Low reliability, and mostly expensive

In short, none of the lifting and transporting devices in the prior art is an economical and applicable device with a simple structure, especially not suitable for grabbing, lifting, and transporting workpieces in local high-temperature areas
