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 hoisting and transporting machinery, and relates to a mechanical device for grabbing, lifting and transporting workpieces from a local high-temperature zone. Background technique [0002] Commonly used lifting and transporting devices in factories, such as CD-type cranes, do not have the function of automatically grabbing objects in terms of their hook structures. However, 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 machinery itself does not provide the feedback signal of "whether it has caught the object", whether it has caught the object (workpiece) needs to be judged by the operator. 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...

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
