Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of garden engineering, and particularly relates to a high-strength flexible cable. BACKGROUND

[0002] Trees are the framework of urban landscaping, and with the planning and development of urban construction, there are a large number of trees in various gardens, communities and other public areas. The coastal areas of southern China experience a typhoon season from July to September every year, and heavy rain and typhoons can affect trees, causing branches to sway excessively in the wind and leading to situations that can easily injure people nearby and cause economic losses.

[0003] Currently, the main measures to protect trees from typhoons are to trim the trees before the typhoon arrives to reduce the risk, and to protect the trees by supporting them. Common tree supports include single-pole supports, door-shaped supports, inverted-V-shaped supports, triangular supports, quadrangular supports, cross-shaped supports, multi-pole supports, cable supports and underground supports. For the main branches of high tree crowns, rigid cables can be used to fix the main branches at a height and combine with elastic support rods to support them. However, for some rotten trees or trees with brittle branches, rigid cables should not be used to fix the branches, as this can make the branches more prone to breaking under wind load. Moreover, the part of the existing rigid cable that connects to the branch has a small contact area, and the rigid cable is hard, which can easily damage the tree. There is also a certain risk.

[0004] If a flexible cable is used, it will be tightened under wind load when affected by the wind, causing the middle of the flexible cable to contract, which can cause stress concentration in the middle of the flexible cable, making the cable prone to being pulled apart, broken or deformed in the middle, losing its elasticity and failing. INVENTION CONTENTS

[0005] To solve the problem of existing flexible cables used for branch traction that are prone to breaking and deforming in the middle when subjected to wind load, the utility model aims to provide a high-strength flexible cable.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A high-strength flexible cable includes a cable and a flexible ring-shaped sling. The cable is a hollow ring-shaped belt structure used to generate a dynamic traction force on the branches of a tree. A reinforcing element is filled in the middle of the cable to prevent excessive deformation of the cable after being subjected to tensile stress. The flexible ring-shaped sling is wrapped around the branches and is arranged at both ends of the cable to form traction on the branches together with the cable.

[0008] Preferably, the reinforcing element is a shuttle-shaped rubber rod.

[0009] Preferably, the pull cable is a dynamic pull cable rope.

[0010] Preferably, the dynamic pull cable rope is formed by PP nylon rope weaving.

[0011] Preferably, the two ends of the flexible ring-shaped sling are wrapped around the tree branches, and are connected to the ends of the pull cable through the double hooking line device.

[0012] Preferably, the reinforcing element is a shuttle-shaped rubber rod.

[0013] The utility model discloses a beneficial effect is:

[0014] The utility model discloses a kind of high-strength flexible cable, reinforcing element is filled in the middle of pull cable;When being influenced by wind force, reinforcing element supports the middle part of pull cable, can effectively prevent that pull cable is shrunk in the middle position, produces tensile crack, tensile break or deformation loses elasticity etc.

[0015] Meanwhile, the utility model wraps around the branch by using flexible ring-shaped sling, so that the pull cable connects the branch and the main stem of the tree together, under the action of wind load, the branch will swing, the flexible ring-shaped sling and the pull cable form dynamic traction on the branch, and dissipate part of wind energy through damping effect, reduce the damage of wind load to the tree, when the tree with safety hazard (rotten tree or branch texture is relatively fragile) is pulled, the flexible ring-shaped sling and the pull cable reduce the swing range of the branch, so that it consumes part of wind energy through local swing, and does not tend to break under wind load. Meanwhile, the flexible ring-shaped sling does not enter the tree, and has less effect on the connection between the branch and the tree, so that the connection is not damaged, and the use is safer and more effective.

[0023] In this embodiment, as shown in Figure 1 and Figure 7 A high-strength flexible cable includes a pull cable 2 and a flexible loop sling 3. The pull cable 1 is used to connect two branches of a tree and forms a dynamic traction force on the branches. The flexible loop sling 3 is wrapped around the branches and is arranged at both ends of the pull cable 1 to form traction on the branches together with the pull cable 1. The pull cable 1 is filled with a reinforcing element 2 in the middle, which is a shuttle-shaped rubber rod. When affected by wind, the pull cable 1 is tightened under the action of wind load, so that the loop-shaped belt structure woven by PP nylon ropes is tightened in the middle, so that the tensile stress formed by the wind load is concentrated in the middle of the pull cable 1, so that the pull cable 1 is easily torn, broken, or deformed to lose elasticity and thus fails. The reinforcing element 2 filled in the middle of the pull cable 1 can support the middle position of the pull cable 1, effectively preventing the pull cable 1 from being excessively tightened in the middle position and causing tearing, breaking, or deformation to lose elasticity, thereby effectively improving the use strength of the pull cable 1 and extending the service life of the pull cable 1.

[0024] In addition, the flexible loop sling 3 is wrapped around the branches in this embodiment, so that the pull cable 1 connects the branches and the trunk of the tree together. Under the action of wind load, the branches will sway, and the flexible loop sling 3 and the pull cable 1 form a dynamic traction force on the branches and dissipate part of the wind energy through damping, thereby reducing the damage of wind load to the tree. When the tree with safety hazards (rotten trees or branches with relatively weak texture) is pulled, the flexible loop sling 3 and the pull cable 1 reduce the swing range of the branches under the action of wind, so that part of the wind energy is consumed through local swinging of the branches, and the branches are not broken due to excessive swing under the action of wind load. At the same time, the flexible loop sling 3 does not enter the tree, has less effect on the connection between the branches and the tree, and does not damage the connection, so it is safer and more effective to use.

[0025] In this embodiment, the pull cable 1 is a dynamic pull cable rope. Specifically, the dynamic pull cable rope is woven by a plurality of PP nylon ropes to form a hollow loop-shaped belt structure, and the two ends of the flexible loop sling 2 are fixed in the loop-shaped belt structure at the same end of the pull cable 1 after being wrapped around the trunk by a locking structure.

[0026] In the embodiment, the two ends of the flexible ring-shaped sling 3 are locked together with the pull cable 1 by pulling ropes 31 through the first anchoring holes of the end of the pull cable 1.

[0027] In another embodiment, as shown in Figure 2 and Figure 3 , the two ends of the flexible ring-shaped sling 3 are provided with second anchoring holes 32, and the flexible ring-shaped sling 3 is locked together with the pull cable 1 by anchoring elements through the first anchoring holes 11 and the second anchoring holes 32 in sequence after the two ends of the flexible ring-shaped sling 3 enter the inside of the pull cable 1. The anchoring elements can be draw pins, bolt assemblies, etc.

[0028] In yet another embodiment, as shown in Figure 4 , the flexible ring-shaped sling 3 is tied together with the pull cable 1 by a binding rope 4 through the first anchoring holes 11 and the second anchoring holes 32 in sequence after the two ends of the flexible ring-shaped sling 3 enter the inside of the pull cable 1.

[0029] In other embodiments, the two ends of the flexible ring-shaped sling 3 are connected to the end of the pull cable 1 by double hooking line devices or ratchet tighteners after being wrapped around the tree branches. The double hooking line devices and the ratchet tighteners are commercially available products, which will not be described here.
