Deck beam structure of grab bucket with weight of 50 tons or above

Abstract

The invention relates to a deck beam structure of a grab bucket with the weight of 50 tons or above. The deck beam structure comprises a front wall plate of a deck beam, a rear wall plate of the deck beam, a left upper wall plate of the deck beam, a right upper wall plate of the deck beam, a left lower wall plate of the deck beam, a right lower wall plate of the deck beam, a top surface plate of the deck beam and a bottom surface plate of the deck beam, wherein the front wall plate of the deck beam and the left upper wall plate of the deck beam are in rounded corner transition; the front wall plate of the deck beam and the right upper wall plate of the deck beam are in rounded corner transition; the rear wall plate of the deck beam and the left upper wall plate of the deck beam are in rounded corner transition; the rear wall plate of the deck beam and the right upper wall plate of the deck beam are in rounded corner transition. According to the deck beam structure, the four corners of the deck beam are changed into rounded corner structures; when the deck beam is held by a steel wire rope, the steel wire rope is lifted and can smoothly get away from the deck beam due to the rounded corner transition, so that the steel wire rope is not caught by the deck beam, and the situation that operation can not be carried out can be avoided.

Description

technical field [0001] The invention relates to an upper bearing beam structure of a mining machine, in particular to an upper bearing beam structure of a grab bucket of 50 tons or above. Background technique [0002] At present, the upper bolster structure of grab buckets of 50 tons and above: the four corners of the upper bolster are right angles. During the operation, when the steel wire rope of the grab hangs down, it is easy to catch the upper bolster. It is a right-angle structure, and the steel wire rope will be hung at a right angle, making the grab bucket unable to perform operations. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide an upper bolster structure with a grab bucket of 50 tons or more that will not hang on the wire rope during hoisting and has a simple structure. [0004] According to the technical solution provided by the present invention, the upper bolster structur...
