Abstract
The utility model discloses a windproof cable for a portal crane lifting appliance. The cable is characterized in that the cable comprises a weighting component group and a group of small cable cores, wherein the weighting components are surrounded by the small cable cores; each group of the small cable cores comprises one weighting component and a group of wire core conductors, and the weighting component is surrounded by the wire core conductors; a wire core insulating layer is wrapped outside each of the wire core conductors; the cable is sequentially provided with an inner protective layer and an outer protective layer from inside to outside; and a group of tearing wires are arranged at the inner side of the outer protective layer. The cable has the advantages that: 1. as the weighting is carried out on the internal part of the cable by lead bead chains, the whole cable has greater weight, therefore, the cable has excellent windproof capacity; and 2. with the adoption of the tearing wires, the sheath of the cable can be conveniently stripped when the cable is in installation.
Description
Technical field
The utility model discloses a kind of wind-proof portal crane suspender cable easy to use.
Background technology
Along with the establishment day by day of economical globalization tendency, and the general layout that the trade of world's staple commodities still mainly relies on the harbour strengthens day by day, and the construction at harbour has all over the world expedited the emergence of the modernization construction of harbour machinery.Wherein the portal crane private cable of high-grade, high-quality (being called for short the dynamo-electric cable in port) has been served as extremely important role undoubtedly.Because the operating state of portal crane has frequently determined supporting with it cable must possess remarkable mechanicalness, flexibility with operation, and the characteristic that resists frequent bending and reel.In this field, the external import cable of famous brand name is being dominated the dynamo-electric cable market, high-end port of China for a long time always, this class import cable is by feat of the quality characteristic and relative long useful life of excellence, cable has been possessed than high added value, and their product is the cage China's Port Machineries private cable market of breaking almost.Thereby make domestic cables manufacturing already wish to break this technology, price fixing as early as possible, recapture market price power and become inevitable trend.
This private cable that is used for crane hanger, the folding and unfolding with the oscilaltion of suspender.Holding the cable mode adopts vertical to hold cable basket coiling collection.The characteristics of this cable are to have adopted wind resistance anti-shake technology, promptly at the inner windproof counterweight element of lead sweat chain that adds of cable, increase the deadweight of cable with appropriateness, keep the bob degree that hangs down when guaranteeing cable work.
The utility model content
The utility model purpose: technical problem to be solved in the utility model is at the deficiencies in the prior art, and a kind of wind-proof portal crane suspender cable is provided.
Technical scheme: the utility model discloses a kind of wind-proof portal crane suspender cable, comprise that one adds the heavy parts group and centers on the one group of small cable core that increases the weight of arrangement of parts, every group of small cable core comprises that one adds heavy parts and centers on the one group of core conductor that increases the weight of arrangement of parts, the every core conductor outside is coated with the core insulating barrier, cable is by interior sheath and the outer jacket of being provided with successively outward, and the outer jacket inboard is provided with one group of tear line.
In the utility model, preferably, the described heavy parts that adds increases the weight of with the lead sweat chain, and the braiding of lead sweat chain warp polyamide staple fibre spun yarn adds cover and handles.Thereby make cable that bigger deadweight be arranged, keep the bob degree that hangs down when guaranteeing cable work, the braiding of lead sweat chain warp polyamide staple fibre spun yarn adds cover to be handled, and has reduced the direct friction of metal pair insulation.
In the utility model, preferably, described center adds the heavy parts skin and is provided with the braiding reinforced layer.Reinforced layer can make cable have good flexibility, bending property when possessing preferably mechanical strength, in addition forms between metal parts and insulation and isolates, and reduces the friction to insulation.
Beneficial effect: the advantage that a kind of wind-proof portal crane suspender described in the utility model has with cable: increase the weight of by the lead sweat chain, make cable have bigger deadweight, guarantee certain vertical bob degree during work; By tear line is set, make to make things convenient for sheath to peel off when cable is installed and used.
Description of drawings
Accompanying drawing 1 is the cross sectional representation of wind-proof portal crane suspender with cable.
Embodiment
As shown in the figure, the utility model discloses a kind of wind-proof portal crane suspender cable, comprise that one adds the heavy parts group and centers on the one group of small cable core that increases the weight of arrangement of parts, every group of small cable core comprises that one adds heavy parts 3 and centers on the one group of core conductor 1 that adds heavy parts 3 arrangements, every core conductor 1 outside is coated with core insulating barrier 2, cable is by interior sheath 5 and the outer jacket 6 of being provided with successively outward, and outer jacket 6 inboards are provided with one group of tear line 7.
Small cable core is made up of the core that increases the weight of the lead sweat chain and be centered around around the lead sweat chain of centering; Add heavy parts and place cable core central authorities and small cable core gap respectively, the heavy parts that adds of cable core central authorities has some bursts of stranded the forming of lead sweat chain, and at skin aramid fiber braiding reinforced layer is set, and the heavy parts that adds in small cable core gap then is made of the lead sweat chain of sub-thread.The outer oversheath that coats of cable core is provided with two high strength fibres as tear line in the oversheath inboard.Described cable core use adds heavy parts and increases the weight of, and makes cable can keep certain vertical bob degree in work, adds between heavy parts and the core separator is set, and reduces the friction between metal and the insulation; In the oversheath inboard tear line is set, makes cable be easy to peel off sheath in use, possess good operability.
The utility model provides thinking and the method for a kind of wind-proof portal crane suspender with cable; the method and the approach of this technical scheme of specific implementation are a lot; the above only is a preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.The all available prior art of each part not clear and definite in the present embodiment is realized.
