Abstract

The invention discloses a small material transferring system suitable for an upper side of a pit. The system comprises a crane main beam, a crane cross beam and a crane carriage. A connecting box is arranged on the middle of the bottom end of the crane carriage, a hook is arranged on the bottom of the connecting box, fixed blocks are arranged on two sides of the bottom end of the crane carriage, a telescopic stop lever is arranged on the bottom of each of the fixed blocks, the other end of the telescopic stop lever is fixedly connected to a connecting rod, a connecting block is arranged on one end, far from the telescopic stop lever, of the connecting rod, insertion rods are arranged on the side walls of two ends of the connecting box, and a guide wheel is arranged in the connecting box. According to the system disclosed by the invention, by arranging the telescopic stop levers connected to the connecting box through the connecting rod, the connecting block and the insertion rods on the bottom of the crane carriage, a hook assembly does not swing when the crane carriage main body moves, so that the hook assembly descending to hook an object keeps a vertical movement and the hook assembly is precisely positioned.

Description

technical field [0001] The invention relates to the related technical field of material transfer devices, in particular to a small-scale material transfer system suitable for above pits. Background technique [0002] In the production of the foundry, the main materials that need to be transferred include sand molds, sand boxes, sand cores, castings with sand boxes after pouring, and auxiliary materials such as cold iron, clips, and reinforcing ribs required in the molding process. Among them, sand molds and castings with sand boxes have the largest tonnage, generally around 50t-150t, and a large crane dedicated to pouring is required for lifting during pouring operations. For such a large-scale transfer and lifting operation, in order to adapt to the space of the casting site, the general casting site adopts a pit shape, and the material transfer mainly uses a large bridge-type double-girder crane. When a general large-scale bridge-type double-girder crane picks up an objec...
