Abstract
The invention relates to a five-jaw semi-opening type steel grabbing machine grab bucket. The upper end part of a hanging bracket is provided with a hanging bracket pin shaft, and the lower end part of the hanging bracket is hinged with a middle bearing beam; a valve block is fixed on the middle bearing beam, and the side faces of the valve block are provided with main crane connection oil ports; the lower end part of the middle bearing beam is hinged with five bucket bodies, and the upper end part of the middle bearing beam is hinged with five oil cylinders; the end part of a piston rod of each oil cylinder is hinged at the middle part of the back part of the corresponding bucket body; the oil cylinders and the valve block are connected by hydraulic pipelines. The grab bucket is suitable for grabbing steel scraps with irregular shapes in a cabin, ensures oil supply synchronism of all the oil cylinders through valve block oil distribution, and at the same time, retains the advantage that bucket bodies of an electric hydraulic orange-peel grab bucket can be asynchronously closed due to different loads; and the grab bucket has the advantages of simple structure and convenient use, and can greatly improve the production efficiency.
Description
Technical field
The present invention relates to a kind ofly for capturing the grab bucket of irregular steel scrap, the present invention especially relates to a kind of five lobe semi-open type steel grasping machines grab buckets.
Background technology
At present, steel scrap generally adopts steamer to transport, and when transport, steel scrap is placed directly in the cabin of steamer, and the steel scrap of regular shape can capture with conventional grab bucket in cabin, and the steel scrap of irregular contour, conventional grab bucket is difficult to capture.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of be adapted at capturing in the cabin steel scrap of irregular contour and five lobe semi-open type steel grasping machine grab buckets simple in structure, easy to use are provided.
According to technical scheme provided by the invention, described five lobe semi-open type steel grasping machine grab buckets, comprise suspension bracket, middle bolster and bucket body, be provided with suspension bracket bearing pin in the upper end of suspension bracket, bolster in the middle of being hinged with in the bottom of suspension bracket, on middle bolster, be fixed with valve piece, be provided with main hoisting crane in the side of valve piece and connect hydraulic fluid port, be hinged with five bucket bodies in the bottom of middle bolster, be hinged with five oil cylinders in the upper end of middle bolster, the piston rod end of each oil cylinder is hinged on the back medium position of corresponding bucket body, and oil cylinder is connected by hydraulic tubing with described valve piece; When work, suspension bracket bearing pin connects the arm of main hoisting crane, and main hoisting crane connects hydraulic fluid port and is connected with the hydraulic efficiency pressure system of main hoisting crane.
Described bucket body is evenly distributed on the outer wall of middle bolster.
At the back of bucket body, midline position is connected with reinforcement gusset, and the piston rod end of described oil cylinder is hinged on to be strengthened on gusset.
The present invention is adapted at capturing in cabin the steel scrap of irregular contour, divide oil to ensure the synchronism of each oil cylinder fuel feeding by valve piece, retained electric hydaulic orange-peel bucket each bucket body due to the not identical advantage that can Close asynchronously of load simultaneously, the present invention is simple in structure, easy to use, can greatly enhance productivity.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
This five lobes semi-open type steel grasping machine grab bucket, comprise suspension bracket 6, middle bolster 5 and bucket body 1, be provided with suspension bracket bearing pin 7 in the upper end of suspension bracket 6, bolster 5 in the middle of being hinged with in the bottom of suspension bracket 6, on middle bolster 5, be fixed with valve piece 3, be provided with main hoisting crane in the side of valve piece 3 and connect hydraulic fluid port 8, be hinged with five bucket bodies 1 in the bottom of middle bolster 5, be hinged with five oil cylinders 2 in the upper end of middle bolster 5, the piston rod end of each oil cylinder 2 is hinged on the back medium position of corresponding bucket body 1, and oil cylinder 2 is connected by hydraulic tubing 4 with described valve piece 3; When work, suspension bracket bearing pin 7 connects the arm of main hoisting crane, and main hoisting crane connects hydraulic fluid port 8 and is connected with the hydraulic efficiency pressure system of main hoisting crane.
Described bucket body 1 is evenly distributed on the outer wall of middle bolster 5.
Be connected with and strengthen gusset 9 at the back of bucket body 1 midline position, the piston rod end of described oil cylinder 2 is hinged on to be strengthened on gusset 9.
Whole grab bucket is connected with the arm of main hoisting crane by suspension bracket bearing pin 7, whole grab bucket fuel feeding connects hydraulic fluid port 8 by main hoisting crane and connects main crane hydraulic system and grab bucket valve piece 3, and passes through 4 points of oil of hydraulic tubing to oil cylinder 2, and hydraulic tubing 4 has two-way, one tunnel oil-feed, a road oil return.
Whole grab bucket is motionless, oil cylinder 2 rod chamber oil-feeds, and oil cylinder 2 rodless cavity oil returns, bucket body 1 is opened, and then whole grab bucket declines under main hoisting crane effect, falls on the steel scrap of cabin bottom, starts to capture operation.
Whole grab bucket is motionless, oil cylinder 2 rod chamber oil returns, and oil cylinder 2 rodless cavity oil-feeds, bucket body 1 closure, then whole grab bucket is risen under main hoisting crane effect, and grab bucket departs from stockpile, transports to appointed place discharging, completes crawl operation.
The present invention passes through 3 points of oil of valve piece to oil cylinder 2, by the flexible open and close that realizes bucket body 1 of oil cylinder 2, advantage is without self-powered, main hoisting crane fuel feeding grasp force is large, ensured the synchronism of each oil cylinder 2 fuel feeding by 3 points of oil of valve piece, retained each bucket lobe of electric hydaulic orange-peel bucket due to the not identical advantage that can Close asynchronously of load, the present invention is simple in structure, can greatly enhance productivity simultaneously.
