Single-girder bridge crane handling mechanical hand

Abstract

The invention provides a single-girder bridge crane handling mechanical hand. The single-girder bridge crane handling mechanical hand comprises a girder, a sliding mechanism, a winding system, a lifting guiding frame, a lifting mechanism and a lifting appliance. By arranging the sliding mechanism, the U-shaped guiding frame is connected with the girder through an upper end pulley and a side pulley, the sliding mechanism can slide on the girder conveniently, normal operation of the sliding mechanism is ensured, and left-right swing of the lifting guiding frame can be avoided. By arranging the lifting mechanism, the winding system drives a mechanical hand frame to move up and down through a steel wire rope so that materials can be lifted. By arranging limiting switches, the stroke of the mechanical hand frame is limited through the two limiting switches so as to avoid the phenomenon that the steel wire rope slips or is driven to the top in the operation process of the lifting mechanism.Monitoring information collected by the limiting switches is guided into a crane controller, and the security monitoring function is achieved. By arranging the mechanical hand frame, the mechanical hand can be used in cooperation with any mechanical hand, precisely-positioned automatic material handling can be achieved.

Description

technical field [0001] The invention relates to a crane manipulator, in particular to a single girder bridge crane handling manipulator. Background technique [0002] The single-girder bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the single-girder bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with the widest range and the largest number. [0003] Existing cranes usually use a combination of wire rope and hook to lift materials, but the wire rope will swing when lifting materials, making it difficult to achieve accurate positioning of materials, and there are no protective...

Problems solved by technology

[0003] Existing cranes usually use a combination of wire rope and hook to lift materials, but the wire rope will swing when lifting materials, making it difficult to achieve accurate positioning of materials, and there are no protective measures during the lifting process, which may easily cause wire rope The case of falling out of the slot or the hook rushing to the top
