The utility model content

Technical problem to be solved in the utility model is, overcomes the large-scale square steel of prior art handling and loading and imitates lowly with the rope coil mutual aid system devised for poor peasants, and the steel rope waste is big, and the shortcoming of safety misadventure easily takes place, and a kind of square steel carrying special tool is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: the top of the skip bucket shape box body that opening is relative when using for two, be installed with the hanger of available crane lifting respectively, the openings of sizes of skip bucket shape box body is inserted as suitable can make square steel termination level.

The utility model also has following technical characterictic:

Described skip bucket shape box body, by base plate, erect the side plate be installed in the base plate both sides, be installed in the base plate setting backboard relative with opening with the biside plate back, and the top board composition that is installed in side plate and backboard end face;

On described hanger, be provided be the lifting hole(eyelet) used of steel rope as the Heave Here, lifting hole(eyelet) is located at opening one side of deflection box body;

Described hanger be located on the skip bucket shape box body bearing point about two;

On described skip bucket shape box body, the backboard outside relative with its opening is fixed with handle.

When the handling square steel, earlier with the opening of two skip bucket shape box bodys as wearing the relative two ends that are handled upside down square steel that are enclosed within of shoes, one end of steel rope is tied up on the hanger on the skip bucket shape box body, the other end of steel rope hangs on the suspension hook of crane, the startup crane promptly gets up to be transported to suitable position to the square steel pocket to be put down, take off the skip bucket shape box body at two ends, the square steel left and right sides again by the alongshoreman, promptly finished handling one time, and so forth circulation.

Advantage of the present utility model and good effect be, owing to during this special tool handling square steel, only two skip bucket shape box bodys are enclosed within relatively the two ends of square steel, the steel rope that is through on the hanger hung on the suspension hook of crane, and starting crane can play the square steel pocket; After being transported to suitable position, put down, steel rope on the hanger is loosened, and the skip bucket shape box body of extracting the square steel two ends out is very convenient, carries other square steel after unloading again in the same way, save the time that prior art is tied up square steel, improved the work efficiency of handling and loading;

In addition, during the operation of prior art carrying square steel, manually to tie up at the midway location of square steel, the danger factor of existence are big.After using above-mentioned special tool, the people has avoided the hazardous location of operation only in the operation of the two ends of square steel, has improved the safety of operation widely;

Replace steel rope to tie up the square steel carrying with above-mentioned instrument, do not have the wear problem of binding unit rope.Through measuring and calculating, by every 120 yuan of calculating of cost of tying up square steel with steel rope, year 200000 tons of square steel of loading and unloading, one of the expense of only saving steel rope just reaches more than 10 ten thousand yuan.
