Description

Sling detaching and collecting tool for seamless steel pipe crane operation

Technical Field

The utility model relates to a safety auxiliary device of industrial and mining, the freight industry jack-up operation such as metallurgy, machinery, more specifically say, relate to a suspender that is arranged in seamless steel pipe crane operation shirks and collects frock.

Background

The hoisting operation is a common operation procedure in industrial and mining enterprises, transportation industries and other industries, and the synthetic fiber sling for hoisting is a common sling.

As shown in fig. 1, the lifting synthetic fiber sling is mainly classified into a flat sling and a circular sling according to its type, and has the characteristics of portability in carrying, convenience in maintenance, good chemical resistance, light weight, high strength, difficulty in damaging the surface of a lifted object, and the like, and has gradually replaced a steel wire rope rigging in various fields.

At present, flat hanging straps are widely adopted in the seamless steel tube manufacturing industry, and have replaced a hanging chain and a U-shaped hanging bracket to become a hoisting rigging commonly adopted in the industry due to the characteristics of convenient use and maintenance, no damage to the surface of the seamless steel tube, strong inclusion on the cylindrical appearance of the seamless steel tube and the like. In seamless steel tube manufacturing enterprises, the hoisting and lifting operation frequency of seamless steel tubes is extremely high, and the method is a main logistics process in field logistics transportation and production. Therefore, the reasonable, safe and standard use of the sling is guaranteed, the safety production of enterprises can be promoted from the source, potential safety hazards are eliminated, the orderly transportation of production logistics is guaranteed, and the production cost of the enterprises is reduced.

Because the synthetic fiber braces are mostly made of nylon fibers (polyamide synthetic fibers), polyester fibers (polyester synthetic fibers) and polypropylene fibers (polypropylene synthetic fibers), the synthetic fiber braces are easily damaged by corrosive media and sharp metal pieces. Therefore, when hoisting, hoisting and transporting the seamless steel pipe at present, the synthetic fiber sling and the working procedures thereof have certain defects, namely:

1) sling vulnerable (unsafe condition of the object): at present, an anti-unhooking device is generally installed on a hoisting machine (a travelling crane), and the anti-unhooking device has the function of preventing a sling which is hung in a lifting hook from escaping. Due to the existence of the unhooking prevention device, although the effect of preventing the sling from escaping can be achieved, the burden of operators operating the sling is increased, the hoisting ring of the sling needs to be hung after the unhooking prevention device is opened, then the unhooking prevention device is closed, the operation is very complicated, the hoisting operation is very frequent, and the hidden danger that the finger is crushed and injured by the tongue of the unhooking prevention device exists. Therefore, cable operators generally reject the unhooking prevention device, and the phenomenon of manually rotating the device is more, so that metal structural members such as a tongue pressing piece and a hoop are exposed, and the problems of extrusion, friction, sharp pricks and the like of a synthetic fiber sling are caused, so that unnecessary damage is caused;

2) there are operational safety hazards (unsafe behavior of people): because seamless steel pipe jack-up transportation operation load is loaded, and cylindrical structure folds the back frame, becomes the bundle layer upon layer, and the two belt types of single hook jack-up is refuted, and the suspender easily skidded at seamless steel pipe excircle surface, and the operating personnel is for robbing into the degree, and the regularity is under the state that the suspender has not formed the pretightning force yet, adopts the hand to stir, adjusts the suspender and at the position fixing of seamless steel pipe, and the extrusion injury that can cause the finger without looking after. The best way to eliminate such safety hazards is "man-machine isolation", that is to say complete isolation of the fingers from the harness, which is not possible with current working equipment and processes.

In summary, in the existing seamless steel pipe hoisting and transporting operation, certain potential safety hazards exist in the aspects of operation behaviors of operators, operation states of hoisting riggings and hoisting mechanical parts and the like, corresponding technical improvements need to be implemented, and a special instrument tool is adopted to realize relative isolation between the operators and an operation device, so that the potential accident hazard of finger extrusion injury is eliminated from the source, and the intrinsic safety of equipment and the operation safety construction are further promoted.
