Description

Technical Field

[0001] This application relates to the field of tree trunk support, and more particularly to a bottom support device for a tree trunk support pole. Background Technology

[0002] During the planting process, due to external factors such as gravity and wind, the trunk of a tree will tilt, causing the tree to bend and seriously affecting its normal growth. Currently, people use support poles to support the trunk of the tree.

[0003] Due to variations in soil looseness across different regions, in areas with loose soil, particularly during vegetation restoration and reconstruction along riverbanks, the support poles used to transplant large, rare trees may sink upon contact with the ground. In winter, freeze-thaw cycles and frost heave can cause soil displacement at the base of the tree, reducing the stability of the support poles in supporting the trunk. This unstable root system leads to a lower survival rate for transplanted large trees, making them unable to overwinter. Therefore, a trunk support pole bottom support device is needed. By installing the support device on the ground and then fixing it to the bottom of the support pole, the ground can support the bottom of the support pole through the support device, thereby improving the stability of the bottom position of the trunk support pole and ultimately enhancing the stability of the support pole's support for the trunk. Utility Model Content

[0004] To address the existing technical problems, this application provides a tree trunk support pole bottom support device. By setting the support device on the ground and then fixing the support device to the bottom of the support pole, the ground can support the bottom of the support pole through the support device, thereby improving the stability of the bottom position of the tree trunk support pole and thus improving the stability of the support pole's support for the tree trunk, thereby solving the problems mentioned in the background art.

[0005] This application provides a tree trunk support pole bottom support device, which adopts the following technical solution: A tree trunk support pole bottom support device includes a carrier plate: an arc-shaped plate is welded to the top of the carrier plate, an insert rod is welded to the bottom of the carrier plate, a threaded rod is threadedly connected to the surface of the arc-shaped plate, the end of the threaded rod passes through to the outside of the arc-shaped plate and is rotatably connected to a clamping block, a slider and a slide rail are provided below the clamping block, a handle is fixedly connected to the rear end of the threaded rod, two symmetrically arranged U-shaped blocks are welded to the top of the carrier plate, an internally threaded lug is welded to the top of the carrier plate, a bolt rod is threadedly connected to the inner wall of the internally threaded lug, and a hanging ring is rotatably connected to the end of the bolt rod.

[0006] By adopting the above technical solution, the insertion rod is inserted into the ground and the carrier plate is stably supported on the ground. Then, by rotating the threaded rod, the clamping block is moved and squeezed and limited on the bottom surface of the support rod. It is then fixed to the U-shaped block on the left side by a rope. The other end of the rope is then passed through the U-shaped block on the right side and fixed to the hanging ring. Finally, by rotating the bolt rod, the rope is tightened and fixed to the surface of the support rod. This achieves the goal of improving the stability of the bottom position of the tree trunk support rod by setting up a support device on the ground and then fixing the support device to the bottom of the support rod, so that the ground can support the bottom of the support rod through the support device. This improves the stability of the support rod's support for the tree trunk.

[0007] Preferably, the bottom end of the insertion rod is integrally formed with a guide block, which is a conical head block.

[0008] By adopting the above technical solution and setting the guide block, the resistance when inserting the rod into the ground is reduced, avoiding the situation where it takes a lot of effort to insert the rod into the ground, thereby improving the convenience of inserting the rod into the ground.

[0009] Preferably, the top of the carrier plate has a slot.

[0010] By adopting the above technical solution and setting the slot, the contact area between the bottom end of the support rod and the carrier plate is increased, thereby improving the stability of the connection between the bottom end of the support rod and the carrier plate.

[0011] Preferably, the slider and the clamping block are fixedly connected, the slide rail and the carrier plate are fixedly connected, and the slider and the slide rail are slidably connected.

[0012] Preferably, a connecting plate is welded together between the carrier plate and the arc-shaped plate.

[0013] By adopting the above technical solution and setting the connecting plate, the welding between the carrier plate and the arc plate is strengthened, avoiding the possibility of breakage at the connection due to the small welding surface, thereby improving the stability of the connection structure.

[0014] Preferably, the surface of the U-shaped block on the right side is coated with a wear-resistant coating.

[0015] By adopting the above technical solution and applying a wear-resistant coating, the U-shaped block on the right side is treated to prevent wear on the surface of the U-shaped block when the rope moves on it, thereby extending its service life.

[0016] Preferably, the inner wall of the slider is embedded with rolling balls, and the rolling balls are in contact with the surface of the slide rail.

[0017] By adopting the above technical solution, the ball bearings are used to pad the slider and the slide rail, avoiding excessive wear when they are in direct contact, thereby extending their service life.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] Example 1:

[0031] Combination Figures 1-3 This application discloses a tree trunk support pole bottom support device, including a carrier plate 1: an arc-shaped plate 2 is welded to the top of the carrier plate 1, and an insertion rod 3 is welded to the bottom of the carrier plate 1. A threaded rod 6 is threadedly connected to the surface of the arc-shaped plate 2. The end of the threaded rod 6 extends to the outside of the arc-shaped plate 2 and is rotatably connected to a clamping block 7. A slider 8 and a slide rail 9 are provided below the clamping block 7. A handle block 11 is fixedly connected to the rear end of the threaded rod 6. Two symmetrically arranged U-shaped blocks 12 are welded to the top of the carrier plate 1. An internally threaded ear block 13 is welded to the top of the carrier plate 1. A bolt rod 14 is threadedly connected to the inner wall of the internally threaded ear block 13. A hanging ring 15 is rotatably connected to the end of the bolt rod 14. A guide block 4 is integrally formed at the bottom of the insertion rod 3. The guide block 4 is a conical head block. By setting the guide block 4, the resistance when the insertion rod 3 is inserted into the ground is reduced, avoiding the situation where it is difficult to insert the insertion rod 3 into the ground, thereby improving the convenience of inserting the insertion rod 3 into the ground.

[0032] Example 2:

[0033] Combination Figures 1-3The top of the carrier plate 1 has a slot 5, which increases the contact area between the bottom end of the support rod and the carrier plate 1, thereby improving the stability of the connection between the bottom end of the support rod and the carrier plate 1. The slider 8 and the clamping block 7 are fixedly connected, the slide rail 9 and the carrier plate 1 are fixedly connected, and the slider 8 and the slide rail 9 are slidably connected. A connecting plate 10 is welded together between the carrier plate 1 and the arc plate 2. The connecting plate 10 strengthens the weld between the carrier plate 1 and the arc plate 2, preventing the connection from breaking due to the small weld surface area, thereby improving the connection structure. To ensure stability, the surface of the U-shaped block 12 on the right side is coated with a wear-resistant coating 16. The wear-resistant coating 16 makes the U-shaped block 12 wear-resistant, preventing the surface of the U-shaped block 12 from being worn when the rope moves on the surface of the U-shaped block 12, thereby extending its service life. The inner wall of the slider 8 is embedded with rolling balls 17. The balls 17 are in contact with the surface of the slide rail 9. The balls 17 are used to pad the slider 8 and the slide rail 9, avoiding excessive wear when they are in direct contact, thereby extending their service life.

[0034] Working Principle: When using this utility model, the user inserts the insertion rod 3 into the ground and firmly supports the carrier plate 1 on the ground. Then, the support rod is fixed to the tree trunk, and the bottom end of the support rod is placed in the inner cavity of the slot 5. Subsequently, by rotating the threaded rod 6, the clamping block 7 is moved and squeezed and limited on the bottom surface of the support rod. During this process, the movement of the clamping block 7 is limited by the cooperation of the slider 8 and the slide rail 9, which improves the stability of the clamping block 7 during movement. It is fixed to the left U-shaped block 12 by the rope. Then, the other end of the rope is wrapped around the surface of the support rod and passed through the right U-shaped block 12 and fixed to the hanging ring 15. Then, by rotating the bolt rod 14, it moves in the inner cavity of the internal threaded ear block 13 and drives the rope to tighten and fix the surface of the support rod through the hanging ring 15. This realizes that by setting a support device on the ground and then fixing the support device to the bottom end of the support rod, the ground can support the bottom end of the support rod through the support device, thereby improving the stability of the bottom end of the tree trunk support rod and thus improving the stability of the support rod for the tree trunk.

[0035] In summary, this trunk support pole bottom support device uses a rod 3 inserted into the ground to firmly support the carrier plate 1. Then, rotating the threaded rod 6 moves the clamping block 7, which presses and limits the bottom surface of the support pole. The clamping block is then fixed to the left-side U-shaped block 12 via a rope. The other end of the rope passes through the right-side U-shaped block 12 and is fixed to the hanging ring 15. Finally, rotating the bolt rod 14 tightens the rope to secure the support pole surface. This achieves the goal of improving the stability of the trunk support pole's bottom position by providing support to the ground and fixing it to the bottom of the support pole.

[0036] Experiment 1: Bearing Capacity Test of Support Rod Bottom Support Device

[0037] The support rod bottom support device of this experiment was applied to the construction project of the Bahekou flood storage and detention area in Chaoyang District, Beijing, during the restoration and reconstruction of vegetation on both banks of the river. The vegetation was planted in early September 2024, and large trees (metasequoia) were transplanted into the loose soil on both banks of the river. Each tree trunk was bound with three cylindrical support rods, and the bottom of each support rod was connected to the support rod bottom support device of this application. The control group was not connected to the support device and was directly supported on the surface soil. The main study is on the influence of different support structure methods on mechanical properties. Specifically, the system was set up on the same land and the design system of this application was used at the end of October of that year to simulate the erosive force of rainfall runoff. The raindrop diameter was selected as 5 mm, the raindrop flow velocity was 9.11 m / s, and the surface water flow depth was 100 mm. The influence of different structures on the mechanical performance parameters (tensile strength, elongation at break) of the connected design structure of this application was simulated and calculated. In addition, in December of that year and February of 2025, the soil displacement changes in the area of ​​the bottom support poles of the transplanted trees were measured (the quadrat was 1m*1m centered on the bottom of the tree), and the freeze-thaw tilt angle was the tilt angle of the soil movement along the vertical direction.

[0041]

[0042] Experimental Results: As shown in Table 1, the structure of this application not only considers the stability requirements of transplanting large trees, but also the impact of ground instability during rain erosion. This application cleverly utilizes a rotating threaded rod to move the clamping block and compress and limit the bottom surface of the support rod. This allows the ground to support the bottom of the support rod by setting a support device on the ground and then fixing the support device to the bottom of the support rod. The guide block reduces the resistance when the rod is inserted into the ground, and the slot increases the contact area between the bottom of the support rod and the carrier plate, thereby improving the stability of the connection between the bottom of the support rod and the carrier plate. The connecting plate reinforces the weld between the carrier plate and the curved plate, preventing breakage at the connection due to the small weld surface area.

[0043] The combined use of the aforementioned components results in a bottom support structure with superior support and mechanical properties. The mechanical performance of the structure in this embodiment is even better, exhibiting higher tensile strength and lower elongation at break compared to structures without a bottom support structure. This demonstrates that the mechanical performance parameters after simulating rainfall runoff erosion force tests using this novel structure are superior, especially for transplanting in loose soil along river embankments.

[0044] The soil on both sides of the river is loose and greatly affected by the erosion of the river water. Therefore, it is prone to repeated freezing and thawing in winter. The support device of this application is particularly effective against soil erosion in transplanted large trees. The support structure of this application is especially suitable for the preparation and restoration area on both sides of the river. Due to the influence of the erosion force of the river water, it avoids the problem of soil displacement caused by freezing and thawing in winter. The soil displacement change in the area of ​​the bottom support rod of the transplanted tree using this structure is small. The soil surface freezing and thawing tilt angle in winter is significantly lower than that of the bottom area of ​​the tree without a support structure. Therefore, using this application can not only stably support the tree trunk, but also prevent the bottom soil area from freezing and thawing displacement, further ensuring the overwintering of transplanted large trees.
