Abstract
The utility model relates to an anti-fatigue spiral cable. The anti-fatigue spiral cable comprises a spiral cable, wherein a tow rope is fixedly connected to the spiral cable; each segment of the tow rope and the spiral cable is provided with a node; and a rope section is arranged between two adjacent nodes. The anti-fatigue screw cable has the advantages of effectively preventing mechanical fatigue phenomenon of the spiral cable, preventing the spiral cable from holding a rod and effectively preventing safety accidents caused by breakage of the spiral cable due to the arrangement of the tow rope, along with simple structure, low cost and convenient use.
Description
Technical field
The utility model relates to a kind of spiral cable, specifically a kind of antifatigue spiral cable.
Background technology
Spiral cable claims spring wire, spring cable or spring electric wire again, is that a kind of scalability of cable screw that utilizes comes the interfacility link of work, is widely used in various mobile devices and the jacking equipment.
As shown in Figure 1, spiral cable more than 1 adopts rubber plastic pipe as the elasticity outsourcing material, in multicore cable is arranged, be the spring-like of different-diameter, have good retractility.In actual applications, if spiral cable is in the state above its elastic deformation limit for a long time, can cause taking place plastic deformation, lose original elasticity, this phenomenon is referred to as mechanical fatigue technically.When spiral cable was used for vertical lifting equipment, because the effect of gravity, superposed cable can be subjected to bigger pulling force than the cable that is positioned at the below usually, and level of stretch is bigger, therefore the easier mechanical fatigue phenomenon that causes cable.
As shown in Figure 2, when spiral cable 1 vertical applications reached ten several meters, because of mechanical fatigue elasticity weakens, cable can be wrapped on elevating lever 2 bodies of rod, and this phenomenon is commonly called the pole phenomenon of spiral cable.Pole can cause the rising of the elevating lever body of rod to be hindered, and more likely can cause cable 1 to rupture because of the rising pulling force of elevating lever 2, produces safety problem.Such situation is ubiquity in large-scale jacking equipment, is puzzlement user and supplier's a big technical barrier.Common solution is the spiral cable that more renews, or in spiral cable generation mechanical fatigue, adopts steel wire, rope that cable is bundled in stopgap measure such on the elevating lever 2, not only strengthens maintenance cost, also fails to tackle the problem at its root.
Summary of the invention
The utility model provides a kind of antifatigue spiral cable at the problems referred to above, and this cable can effectively prevent the generation of pole phenomenon, guarantees the normal operation of jacking equipment.
According to the technical solution of the utility model: a kind of antifatigue spiral cable, comprise spiral cable, be fixedly connected with towline on the described spiral cable, each link of described towline and described spiral cable has a node, is provided with ran between two adjacent nodes.
Being centered close on same the straight line of all nodes.
The equal in length of all rans.
Described spiral cable comprises multicore cable, and the outside of multicore cable is coated with rubber plastic pipe.
The material of described towline is a nylon.
Technique effect of the present utility model is: the utility model has prevented the mechanical fatigue phenomenon of spiral cable effectively by increasing towline, avoids spiral cable generation pole phenomenon, has prevented effectively that spiral cable is torn and the security incident that takes place; Simple in structure, with low cost, easy to use.
Description of drawings
Fig. 1 is the structural representation of spiral cable of the prior art;
Fig. 2 is the schematic diagram of spiral cable pole phenomenon of the prior art;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is application state figure of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
As shown in Figure 3, the utility model is a kind of antifatigue spiral cable, is to improve to form on the basis of common spiral cable 1.Spiral cable 1 is made up of the rubber plastic pipe 7 that the outside of multicore cable 8 and multicore cable 8 is coating.The utility model increases a towline 3 on common spiral cable 1, the material of towline 3 can adopt fiber crops, cotton, nylon etc.Towline 3 has a node 5 with each link 4 of spiral cable 1, is provided with ran 6 between two adjacent nodes 5.Being centered close on same the straight line of all nodes 5.The equal in length of all rans 6.
As shown in Figure 4, when the utility model was used for elevating lever 2, the upper end of towline 3 was connected with the top of elevating lever 2, and the lower end of towline 3 is connected with the bottom of elevating lever 2.When spiral cable 1 moved with elevating lever 2, towline 3 pulling spiral cables 1 evenly rose, and the spacing between spiral cable 1 each link 4 equates.
The utlity model has following advantage:
1, effectively prevents the mechanical fatigue phenomenon of spiral cable, prolonged its service life.
2, effectively prevent the pole phenomenon of spiral cable, guarantee that jacking equipment normally moves.
3, prevent that effectively spiral cable is torn, avoided the generation of security incident.
4, simple in structure, with low cost, easy to use.
