Grabbing-bucket bridge crane

Abstract

The invention discloses a grabbing-bucket bridge crane. The grabbing-bucket bridge crane comprises a box bridge frame, trolley traveling mechanisms, a crab and a grabbing bucket, wherein fixing frames are mounted at two ends of the box bridge frame; the box bridge frame is transversely and horizontally erected at the upper ends of the fixing frames; the trolley traveling mechanisms are arranged on the fixing frames; a crab traveling track is arranged on the box bridge frame; the crab is glidingly connected to the crab traveling track; a grabbing bucket driver is arranged on the crab; a steel wire lifting rope is guided out of the lower end of the grabbing bucket driver; the grabbing bucket is connected to the lower end of the steel wire lifting rope; a cover plate is mounted at the upper end of the grabbing bucket; and the steel wire lifting rope is positioned in the center of the cover plate. Therefore, the grabbing-bucket bridge crane is capable of carrying granular materials such as ores, cokes, coal, gravel and the like indoors or outdoors; and the cover plate is mounted at the upper end of the grabbing bucket, so that the function of fixing the steel wire lifting rope can be achieved and the dust can be prevented.

Description

technical field [0001] The invention relates to the field of cranes, in particular to a grab bridge crane. Background technique [0002] Grab cranes refer to lifting machinery equipped with grab buckets, which are widely used in ports, docks, station freight yards, mines, etc. to load various bulk cargo, logs, minerals, coal, sand and gravel, earth and stone, etc. An automatic fetching machine, its grabbing and unloading actions are controlled by the driver of the ship unloader, without the need for auxiliary personnel, thus avoiding the heavy labor of workers, saving auxiliary working time, and greatly improving the loading and unloading efficiency. Grab cranes are roughly divided into bridge grab cranes, gantry grab cranes, and folding arm grab cranes. Bridge grab cranes are suitable for large mining industries, etc. However, the traditional bridge grab crane directly uses the grab bucket to grab sand and soil, and the grab bucket will not be dust-proofed during work, so ...
