Unmanned heavy gantry transfer clamping claw

Abstract

The invention provides an unmanned heavy gantry transfer clamping claw. The unmanned heavy gantry transfer clamping claw comprises a gantry frame, wherein at least two frames capable of moving relative to each other are arranged on the inner wall of the gantry frame, fixing sleeves capable of moving in an extendable mode along inner cavities of the frames are arranged on the two opposite side walls of a frame base, moving blocks capable of moving in an extendable mode in the vertical direction of the fixing sleeves are arranged on the fixing sleeves, the bottom ends of the moving blocks are rotationally provided with claw clamping assemblies for grabbing objects, each frame comprises two side plates which are oppositely arranged on the side walls of the base in parallel, and the two side walls, in the length directions of the side plates, of the base are provided with hydraulic cylinder sets used for driving the fixing sleeves to move in the length directions of the two side plates. The plurality of frames in the gantry frame can be adjusted to be evenly distributed on the periphery of goods according to the size and shape of the goods, so that the number of contact points with the goods is increased, and stable clamping and transferring treatment on the goods is achieved; and in addition, the plurality of frames can clamp the plurality of goods at a time, so that the efficiency of hoisting operation is improved favorably.

Description

technical field [0001] The invention relates to the technical field of gantry lifting machinery, in particular to an unmanned heavy-duty gantry transfer gripper. Background technique [0002] Existing hoisting of goods used in large sites such as docks and factories is mostly carried out by cranes and hoisting machines. Generally, corresponding hoisting fixtures are required to clamp the goods, and the traditional hoisting mode of using hooks to hook the goods There are few contact points with the goods, not only the amount of goods grabbed each time is small, but also the stability of the movement of the goods is poor during the process of driving the goods to be transferred, resulting in a low safety factor in the entire lifting process. Contents of the invention [0003] The invention provides an unmanned heavy-duty gantry transfer gripper with stable cargo gripping and transfer and efficient hoisting operation. [0004] In order to solve the problems of the technologi...
