The utility model lies in that overcome the defect of the prior art, it is good, anti-to provide a kind of large carrying capacity, wear-resisting property Pressure energy power is strong, service life length, anti-rotational steel wire rope for tower crane.

In order to solve the above-mentioned technical problem, the utility model provides the following technical solution：

A kind of derrick crane anti-rotating wire rope, the multilayer steel wire rope being made of outer layer strand, internal layer stock and central strand, The outer layer strand is that multiply is compacted stock, and the main stock in outer layer strand wraps in the shape of a spiral twists the internal layer stock, and the internal layer stock is helically Shape packet twists the central strand, and the internal layer stock includes the first internal layer stock and the second internal layer stock, and the second internal layer stock is by second The thin stock of layer and the second inner-layer thick stock composition；The second inner-layer thick stock is embedded in the recess of the first internal layer stock in line contact shape, The second inner-layer thin stock twists the projection portion of the first internal layer stock in line contact shape packet；The second inner-layer thick stock and the second internal layer Thin stock is alternate setting.

Preferably, the central strand is at least formed by three round wires in line contact, helical form twisting.

Preferably, the outer layer strand is at least ten strands of compacting stocks, and the internal layer stock is at least 12 strands of compacting stocks.

Preferably, the first internal layer stock is at least four stocks, and the second internal layer stock is at least eight stocks.

Preferably, the outer layer strand includes the first outer layer strand, the thick stock of the second outer layer, first outer layer strand and the second outer layer Thick stock constitutes ectonexine structure；It is furthermore preferred that first outer layer strand is identical with the steel wire number of the thick stock of the second outer layer, is in face-line Contact shape packet twists the core wire of the outer layer strand.

Preferably, the steel wire of the first internal layer stock and the second inner-layer thin stock is twisted in face contact shape packet in the internal layer stock Heart steel wire, the steel wire of the second inner-layer thick stock twist the core wire of the internal layer stock in face-line contact shape packet.

Preferably, the outer layer strand is in point contact shape packet and twists the internal layer stock.

Compared with prior art, the utility model has following advantageous effect：

The steel wire rope of the utility model design, is changed existing product, the strong spy of formula softness is gulped down using watt woods Internal layer stock of the point as steel wire rope, to improve the wear-resisting property of steel wire rope, the outer layer strand of steel wire rope is by the way of Xi Lushi, steel The rupture pull force of cord directly influences the service life of steel wire rope, so ectonexine stock all uses compacting stock, steel can be improved 20% or more the fracture of cord, reaches that large carrying capacity, wear-resisting property are good, anti-pressure ability is strong, and anti-rotation with long service life has Beneficial effect.

Specific implementation mode

Further explanation below in conjunction with attached drawing to the utility model, it should be understood that it is described herein be merely to illustrate and It explains the utility model, is not used to limit the scope of protection of the utility model.

As shown in figures 1 to 6, steel wire rope for tower crane, the composite steel being made of outer layer strand 5, internal layer stock and central strand 1 Cord, the outer layer strand 5 are that multiply is compacted stock, and the main stock in outer layer strand 5 wraps in the shape of a spiral twists the internal layer stock, the internal layer stock Packet twists the central strand 1 in the shape of a spiral, and the internal layer stock includes the first internal layer stock 2 and the second internal layer stock, the second internal layer stock It is made of the second inner-layer thin stock 3 and the second inner-layer thick stock 4.The second inner-layer thick stock 4 is embedded in the first internal layer stock 2 in line contact shape Recess, the second inner-layer thin stock 3 twists the part of the protrusion of the first internal layer stock 2, second internal layer in line contact shape packet 4 and second inner-layer thin stock 3 of thick stock is alternate setting.

The central strand 1 is at least formed by three round wires in line contact helical form twisting.
