Description

Technical Field

[0001] This utility model belongs to the field of landscape engineering technology, specifically relating to a tree branch and trunk protection and traction device. Background Technology

[0002] Trees form the framework of urban landscaping. With the planning and development of urban construction, a large number of trees exist in various gardens, residential areas, and other public areas. In the coastal areas of South my country, July to September is the typhoon season. Heavy rains and typhoons can affect trees, making their branches and trunks prone to excessive swaying and breakage under the force of the wind. This can easily cause injuries to people in the vicinity and result in economic losses.

[0003] Currently, most tree protection measures in response to typhoon attacks involve pruning trees before the typhoon arrives to reduce risk, or protecting trees by setting up supports. Commonly used tree supports include single-pole supports, portal-shaped supports, A-frame supports, triangular supports, four-corner supports, grid-shaped supports, multi-pole supports, steel cable supports, and underground supports.

[0004] For the main trunk and branches in the upper canopy, the main branches at general heights can be supported using a combination of rigid cables and flexible support rods. However, for some decaying trees or trees with fragile branches, rigid cables should not be used to fix the branches to prevent them from swaying, as this makes the branches more likely to break under wind loads. Furthermore, the contact area between the existing rigid cables and the branches is small, and the rigid cables are relatively hard, which can easily strain or damage the tree, posing a certain risk. Utility Model Content

[0005] To address the issue that existing rigid cable and elastic support combinations can easily become stuck at the connection points of trees in the high canopy sections when exposed to typhoons and other weather conditions, this invention aims to provide a tree branch protection and traction device.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A tree branch protection traction device includes a cable and a flexible ring sling. The cable is used to connect two branches of a tree and to generate a dynamic traction force on the branches. The flexible ring sling is wrapped around the branches and is located at both ends of the cable, together with the cable to form a traction force on the branches.

[0008] Preferably, the cable is a dynamic cable rope.

[0009] Preferably, the dynamic cable is made of PP nylon rope braided together.

[0010] Preferably, after the two ends of the flexible ring sling are wrapped around the tree branches, they are connected to the end of the cable by a double hook tensioner.

[0011] Preferably, the cable is filled with reinforcing elements.

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

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention provides a tree branch protection and traction device. A flexible ring-shaped sling is wrapped around the branch, connecting it to the trunk via a cable. Under wind load, the branch sways, and the flexible ring-shaped sling and cable create a dynamic traction force. This damping effect dissipates some wind energy, reducing the damaging impact of wind load on the tree. When traction is applied to trees with safety hazards (decaying trees or trees with fragile branches), the flexible ring-shaped sling and cable reduce the branch's sway range, allowing it to dissipate some wind energy through localized swaying without causing excessive swaying and breakage under wind load. Simultaneously, the flexible ring-shaped sling does not dig into the tree, minimizing the impact on the connection point and preventing damage to the connection. This makes it safer and more effective to use. Attached Figure Description

[0023] In this embodiment, as Figure 1 The diagram shows a tree branch protection and traction device, which includes a cable 2 and a flexible ring sling 3. The cable 1 is used to connect two branches of a tree (or connect the trunk and branches) and to form a dynamic traction force on the branches. The flexible ring sling 3 is wrapped around the branches and set at both ends of the cable 1, and together with the cable 1, it forms a traction force on the branches. By using a flexible ring-shaped sling 3 wrapped around the branches, the cable 1 connects the branches and trunk of the tree. Under wind load, the branches will sway. The flexible ring-shaped sling 3 and the cable 1 create a dynamic traction force on the branches and dissipate some wind energy through damping, reducing the destructive effect of wind load on the trees. When pulling trees with safety hazards (decaying trees or branches with fragile texture), the flexible ring-shaped sling 3 and the cable 1 reduce the swing range of the branches under wind, allowing them to consume some wind energy through their own local swing, without causing excessive swing under wind load that could lead to breakage. At the same time, the flexible ring-shaped sling 3 will not dig into the tree, and has less impact on the connection between the branches and trunk, preventing damage to the connection point, making it safer and more effective to use.

[0024] In this embodiment, the pull cable 1 is a dynamic pull cable rope. Specifically, a dynamic pull cable rope refers to a rope that, when subjected to external force, can generate dynamic tensile stress on the objects connected at both ends through its own deformation. In this embodiment, the dynamic pull cable rope is woven from multiple PP nylon ropes to form a hollow annular strip structure. The two ends of the flexible annular sling 2 are fixed within the annular strip structure at the same end of the pull cable 1 by a locking structure after passing around the tree trunk.

[0025] In this embodiment, the two ends of the flexible ring sling 3 are locked together with the cable 1 by passing the pull rope 31 through the first anchoring hole at the end of the cable 1.

[0026] In another embodiment, such as Figure 2 and Figure 3 As shown, both ends of the flexible ring sling 3 are provided with second anchoring holes 32. After the two ends of the flexible ring sling 3 enter the cable 1, the flexible ring sling 3 and the cable 1 are locked together by anchoring elements passing through the first anchoring hole 11 and the second anchoring hole 32 in sequence. The anchoring elements can be rivets, etc.

[0027] In yet another embodiment, such as Figure 4 As shown, after both ends of the flexible ring sling 3 enter the cable 1, the binding rope 4 passes through the first anchoring hole 11 and the second anchoring hole 32 in sequence, and then binds the flexible ring sling 3 and the cable 1 together.

[0028] In other embodiments, after the two ends of the flexible ring sling 3 are wrapped around the tree branches, they are connected to the end of the cable 1 by a double-hook tensioner or a ratchet tensioner. Both the double-hook tensioner and the ratchet tensioner are commercially available products and will not be described in detail here.

[0029] In this embodiment, a reinforcing element 2, which is a shuttle-shaped rubber rod, is filled in the middle of the cable 1. When affected by wind, the cable 1 will be tightened under the wind load, causing the annular strip structure woven from PP nylon rope to shrink in the middle. This concentrates the tensile stress formed by the wind load in the middle part of the cable 1, making the cable 1 prone to tearing, breaking, or deformation and loss of elasticity in the middle part, thus causing it to fail. Filling the middle of the cable 1 with the reinforcing element 2 provides support to the middle of the cable 1 when the annular strip structure woven from PP nylon rope shrinks. This effectively prevents the cable 1 from being excessively tightened in the middle, which could lead to tearing, breaking, deformation, or loss of elasticity. This effectively improves the strength of the cable 1 and extends its service life.
