Abstract

The utility model discloses a lifting hook special for a steel tube, and belongs to the technical field of tools for lifting work. The lifting hook is used for lifting the steel tube. According to the technical scheme, the lifting hook consists of a hook head, a hook body and protection plates, wherein the hook head and the hook body are thick steel plates; the hook body is rectangular; the lower part of the rectangular hook body is in a circular arc shape; the hook head is arc; the lower end of the hook head is connected to one side of the upper plane of the hook body; the arc upper end of the hook head is inclined towards the central line of the rectangular hook body; a lifting hook hole is formed at the upper end of the hook head; the protection plates which are connected to form a whole are arranged on the inner side of the hook head and the upper plane of the hook body; the edge of each protection plate is a circular arc surface; and rubber plates are wrapped on the surfaces of the protection plates. The structure of the lifting hook is welded by the thick steel plates; the protection plates are arranged on the surface of the lifting hook, so that relatively high anti-bending intensity and relatively high anti-torsion intensity are realized, and the tube end and the surface coating of the steel tube can be protected effectively; the lifting hook has the advantages of convenience for operation, proper angle, simple structure, light weight, safety, reliability and the like, and is rational stressed, so that a phenomenon that the lifting hook is easy to separate during loading and unloading is avoided, and the working safety is improved; and the working efficiency for loading and unloading the steel tube is improved at the same time.

Description

The special-purpose suspension hook of a kind of steel pipe

Technical field

The utility model relates to a kind of suspension hook that lifts steel pipe, belongs to the lifting operation technical field of tools.

Background technology

At present, the loading and unloading of general steel pipe or cast tube all adopt lifting devices such as hanging belt, steel rope, general suspension hook to carry out.Find in actual use, use hanging belt, steel rope, general suspension hook to have following defective:

1, during general suspension hook operation, coupler body from great, labor strength is high, is prone to break off relations, and is prone to cause the pipe end damage, has serious potential safety hazard;

When 2, adopting the hanging belt pocket to hang operation, wear and tear too early owing to the reason of coming the operation of pumpback hook causes suspender belt and body contact surface, in hoisting process, the back of colliding with is surperficial hard defects occurring, thereby hanging belt is scrapped too early, and the while has also increased productive costs;

When 3, adopting the steel rope pocket to hang operation, often cause steel tube surface to scratch or the finish coat peeling paint.

Therefore, the special-purpose suspension hook that relates to a kind of lifting steel pipe (comprising cast tube and steel pipe) is very necessary.

The utility model content

The utility model technical matters to be solved provides a kind of special-purpose suspension hook of steel pipe that can avoid steel pipe to damage, alleviate labor strength, reduction suspender use cost.

The technical scheme that solves the problems of the technologies described above is:

The special-purpose suspension hook of a kind of steel pipe, it is made up of gib head, coupler body, backplate, and gib head, coupler body are plate iron; Coupler body is a rectangle, and the bottom of rectangle is a circular shape, and gib head is an arc; The gib head lower end is connected a side on plane on the coupler body; The arc-shaped upper ends of gib head tilts to the line of centers of coupler body rectangle, and there is hook on hole the upper end of gib head, and Plane Installation has the backplate that connects as one on gib head inboard and coupler body.

The special-purpose suspension hook of above-mentioned steel pipe, the width of said backplate is greater than the thickness of gib head, coupler body, and the backplate plane is vertical with the plane of gib head, coupler body, and the backplate edge is an arc surface, is coated with rubber plate at backplate.

The special-purpose suspension hook of above-mentioned steel pipe; The angle on plane is 50 °-70 ° on the line of the inboard point of connection in the center of circle of said gib head hook on hole to gib head lower end and the coupler body; The height on plane is 80-120mm on the center of circle of gib head hook on hole to the coupler body, and plane length is 171-185mm on the coupler body.

The usefulness of the utility model is:

The structure of the utility model adopts the plate iron welding; The mounted on surface backplate; Bigger bending resistance, torsional strength are arranged, can also protect pipe end and finish coat effectively, have that easy to operate, angle is appropriate, a reasonable stress, advantage such as simple in structure, in light weight, safe and reliable; Thereby overcome the phenomenon that is prone to unhook in the handling process; Increased operational security, also improved the operating efficiency of loading and unloading steel pipes simultaneously, extensively model is applied to the various steel pipe loading and unloading operations of harbour, station, stockyard, steel mill and camp site.
