Description

Novel automobile crane is used steel wire rope

Technical field

The utility model relates to a kind of lifting, handling rigging, particularly relates to a kind of crane and uses steel wire rope.

Background technology

Along with China's rapid development of economy; Every profession and trade has also proposed different instructions for uses to hoisting appliance especially steel wire rope; The domestic linear contact lay wire rope that generally uses all exists the characteristics that ABRASION RESISTANCE is strong, steel cable is harder like 6 * 29F-IWRC, 6 * 36SW-IWRC etc., though and 35W * 7 multistrand ropes such as grade are soft, ABRASION RESISTANCE is not strong; Crush resistance is not strong, characteristics such as operating difficulties during use.Cause steel wire rope in use the life-span not long, safety coefficient is low, the frequent change steel wire rope has increased the cost that uses.The design's steel wire rope improves common 6 strands contact steel wire rope, has improved bearing capacity, ABRASION RESISTANCE and the resistance to shock loads ability of steel wire rope.

The utility model content

The utility model has been to overcome the defective of prior art, provides strong, the anti-extruding of a kind of ABRASION RESISTANCE, soft novel automobile crane to use steel wire rope.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme:

Comprise the skin that metal core, outer main thigh center on; Said outer main strand of helical form bag twisted with the fingers metal core; Said metal core comprises central strand and outer layer strand, and the said central strand and the outer layer strand outside all are enclosed with plastic coating, and said outer layer strand symmetrically, the rotation bag is twisted with the fingers central strand twist; Said outer main thigh comprises that core wire, internal layer, middle level, skin, said internal layer are face contact shape bag and twist with the fingers core wire, and said middle level is around the internal layer outside, said skin symmetrically, be face and wrap touchingly and twist with the fingers the middle level.

Be line contact shape between said central strand and the outer layer strand.

Said central strand and outer layer strand cross section are circle, and said central strand and outer layer strand are 1 steel wire of 6 steel wire bags sth. made by twisting system of twisting with the fingers and form.

Said outer main strand outer layer cross section is a polygon.

Said outer main strand be Wa Lin gulp down-the Xi Lushi structure forge the compacting thigh.

Said middle level is divided into middle level thick wire and middle level finer wire, and said middle level thick wire is the recess that face embeds adjacent two internal layers touchingly, and said middle level finer wire is face and wraps the bossing of twisting with the fingers steel wire of internal layer touchingly respectively.

Compared with prior art, the utlity model has following beneficial effect:

The design's steel wire rope adopts metal core to be wrapped with the plastic coating structure, guarantees the softness of steel wire rope, can guarantee the ABRASION RESISTANCE of steel wire rope again.Have characteristics such as stronger crush resistance, shock resistance and bearing load are big.

The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; Novel automobile crane is used steel wire rope, comprises metal core, outer main strand 3 skin that centers on, and metal core comprises central strand 1 and outer layer strand 2; Central strand 1 is circle with outer layer strand 2 cross sections; 6 outer layer strand 2 are carried out spirality rotation bag symmetrically and are twisted with the fingers central strand 1, are line contact shape between central strand 1 and the outer layer strand 2, and central strand and outer layer strand are 1 steel wire of 6 steel wire bags sth. made by twisting system of twisting with the fingers and form.Carrying out adopting the injection polyvinyl chloride plastic when metal core is produced; Central strand 1 all is enclosed with plastic coating with outer layer strand 2 outsides; Make metal core become the plastic-coated metal core; Utilize that plastic coating separates between central strand 1 and the outer layer strand 2, the friction of steel wire between the outer layer strand 2, increased the ABRASION RESISTANCE of steel wire rope.Earlier 6 main burst of 3 usefulness, 10% left and right sides compression ratios are forged when closing rope, then the rotation of skin master thigh 3 spiralitys is wrapped the sth. made by twisting moulding around the plastic-coated metal core.

Further describe, outer main strand 3 comprises core wire 4, internal layer 5, middle level 6, skin 7, and internal layer 5 is 6 steel wires, and internal layer 5 is face and wraps sth. made by twisting core wire 4 touchingly; Middle level 6 is divided into middle level thick wire and middle level finer wire; Middle level 6 has 12 steel wires; Wherein 6 middle level thick wires are the recess that face embeds adjacent two internal layer 5 steel wires touchingly, and 6 middle level finer wires are face and wrap the bossing of twisting with the fingers at 6 internal layer 5 steel wires touchingly respectively; Outer 7 is 12 steel wires, outer 7 symmetrically, be face and wrap touchingly and twist with the fingers middle level 6.Outer main strand 3 for " WS " promptly watt woods gulp down-the compacting thigh of Xi Lushi structure, to make 12 section of steel wire of all skins be polygon-shaped through forging compression.The softness of steel wire rope can be guaranteed, the ABRASION RESISTANCE of steel wire rope can be guaranteed again.

Closing outer main strand 3 of 6 of whens rope carries out the spirality rotation system of twisting with the fingers around the plastic-coated metal core and forms; 6 outer main thighs 3 are separately reasonable main strand of every skin through noseplate on finished car; Through behind the pre-former, tight with special line ball mold pressing, eliminate the residual stress in the thigh through the post-former of the many wheels of too much group again; Effectively reduced the construction of wire rope elongation; Metal core behind the plastic-coated time will carry out suitable heating closing rope, and the temperature of heating guarantees that 6 outer main strand 3 can compress metal core smoothly, make its guarantee strand in steel wire maintenance mediate contact in steel wire and the metal core; Reduce the direct friction between the steel wire, thereby reach anti-wear performance, crush resistance and shock resistance, the load performance that improves its steel wire rope.

The above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
