Description

Technical Field

[0001] This utility model relates to the field of construction technology for large-size tree transplantation box panels, and in particular to an auxiliary device for lifting and unloading large-size box panels. Background Technology

[0002] Tree transplantation technology plays a vital role in modern landscaping and ecological protection, especially in the relocation of extra-large trees. Ensuring tree survival rates and transplantation efficiency has become a core concern in the industry. With accelerating urbanization, the demand for the protection and relocation of ancient and famous trees is increasing. The development of related technologies not only relates to the sustainability of the ecological environment but also directly impacts the realization of urban landscape construction and cultural heritage value. Against this backdrop, continuous advancements in tree transplantation technology provide crucial support for ecological protection and landscaping construction.

[0003] In practice, to address the safety and stability issues during the hoisting of oversized trees, the industry typically employs various traditional methods. For example, ordinary steel hoisting beams are directly connected to the crane for lifting, or the tree roots are secured with a simple wooden frame before hoisting. Additionally, simple balancing devices with multi-point force distribution are sometimes used to attempt to distribute the pressure generated during hoisting.

[0004] The aforementioned traditional methods have significant shortcomings when hoisting oversized trees. Due to the large size and weight of the box panels, traditional hoisting methods easily lead to uneven stress on the panels, causing deformation of the box and even damage to the tree's root system, severely impacting the tree's survival rate. Therefore, there is an urgent need for a hoisting technology that can effectively protect the integrity of the box panels and the safety of the tree's root system. Utility Model Content

[0005] This application provides a large-size box-and-panel lifting and unloading auxiliary device, which can effectively improve the stability of trees and the safety of their root systems during transportation.

[0006] This application provides a lifting and unloading auxiliary device for large-size boxes and panels, which adopts the following technical solution:

[0007] A lifting and unloading auxiliary device for large-size box panels includes a steel structure frame, reinforcing ribs, a balance beam, and lifting ropes. The steel structure frame is equipped with reinforcing ribs and has pre-drilled lifting holes. The balance beam has two pre-drilled lifting holes at both ends of its upper part for docking with a lifting hook, and two pre-drilled lifting holes at each end of its lower part for connecting with a lower lifting beam. The lifting ropes are used to connect the crane, the balance beam, and the steel structure frame to each other to achieve lifting.

[0008] By adopting the above technical solutions, this utility model designs a large-size box panel lifting and unloading auxiliary device. During use, the reinforcing ribs enhance the stability of the overall structure, ensuring even distribution of force during lifting and preventing deformation or damage to the box panels due to their own weight. The pre-reserved lifting holes on the steel frame provide precise leverage points for lifting operations, ensuring safety during the lifting process. The lifting holes at both ends of the balance beam achieve stable connection with the hook and the lower lifting beam, effectively preventing the box panels from being squeezed during lifting and protecting the integrity of the tree root system. The lifting ropes connect the crane, balance beam, and steel frame, enabling coordinated operation during the lifting process, improving lifting efficiency, and ensuring a high success rate for tree transplantation.

[0009] Preferably, the steel structure frame is composed of multiple crossbeams, which are connected by angle brackets, and the angle brackets are provided with screws for fixing.

[0010] By adopting the above technical solution, the steel structure frame is composed of multiple beams and connected by corner brackets. The corner brackets are equipped with screws for fixing, thereby realizing convenient assembly and disassembly of the frame.

[0011] Preferably, the surface of the steel structure frame is provided with an anti-slip layer and coated with an anti-rust paint, which not only facilitates the stability of the tree roots but also ensures its service life.

[0012] By adopting the above technical solutions, the anti-slip layer on the surface of the steel structure frame can effectively prevent the tree roots from sliding during hoisting, ensuring the tree roots are placed stably. The anti-rust coating sprayed on the surface of the steel structure frame can effectively prevent rust problems caused by environmental factors during long-term use, extending the overall service life of the device.

[0013] Preferably, the lifting rope connected to the balance beam is adjustable, and it has four lifting holes at different positions. The adjustment is made by connecting the lifting rope to the lifting holes at different positions.

[0014] By adopting the above technical solution, the four lifting holes at different positions on the balance beam can be adjusted by connecting the lifting ropes to the lifting holes at different positions, resulting in different spaces between the lifting ropes. This method is flexible, simple, and lower in cost.

[0015] Preferably, the base length of the balance beam is 1.8 meters, the diameter is 24 centimeters, and the rated load is 100 tons.

[0016] By adopting the above technical solution, the foundation length of the balance beam is set to 1.8 meters during use, which can meet most hoisting requirements while ensuring structural strength. The rated load reaches 100 tons, which greatly improves the load-bearing capacity of the device, meets the hoisting requirements of extra-large tree box panels, and ensures the safety and reliability of the hoisting process.

[0017] Preferably, the wall of the hoisting hole is provided with a wear-resistant layer to further prevent excessive wear and breakage of the hoisting rope during connection.

[0018] By adopting the above technical solution, a wear-resistant layer is applied to the wall of the hoisting hole during use, which effectively reduces the wear of the hoisting rope during the connection process and avoids the risk of the hoisting rope breaking due to excessive wear, thereby improving the safety of the hoisting process.

[0019] Preferably, the hoisting rope includes an upper section connected to the crane and the balance beam and a lower section connected to the balance beam and the steel structure frame, with the length ratio of the upper section to the lower section being 1:3 to 1:4.

[0020] By adopting the above technical solution, when using the equipment, the ratio of the length of the upper section to the lower section is set to 1:3 to 1:4, which can effectively optimize the force distribution during the hoisting process and ensure hoisting stability.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. The present invention relates to a large-size box panel lifting and unloading auxiliary device, which effectively disperses the force during the lifting process through the combination design of steel structure frame, reinforcing ribs and balance beam, avoids the box panel from being squeezed and deformed due to its own weight, and ensures the integrity of the box panel and the safety of tree roots;

[0023] 2. The present invention provides a large-size box lifting and unloading auxiliary device. The combination of the balance beam and the lifting rope changes the traditional direct force-bearing mode of wooden boxes, eliminates the secondary damage to the root system caused by the box compression, and improves the survival rate of trees.

[0024] 3. The auxiliary device for lifting and unloading large-sized box panels designed in this utility model has a reasonable layout of lifting holes and lifting ropes, which realizes the stability and safety of the lifting process and provides a guarantee for the efficient transplantation of extra-large trees.

[0029] This utility model discloses an auxiliary device for lifting and unloading large-size boxes and panels, such as Figure 1 and Figure 2 As shown, the structure includes a steel frame 1, reinforcing ribs 2, a balance beam 3, and lifting ropes 4. The steel frame 1 is equipped with reinforcing ribs 2 and has pre-drilled lifting holes 5. The balance beam 3 has two pre-drilled lifting holes 5 at both ends of its upper part for docking with the hook, and two pre-drilled lifting holes 5 at each end of its lower part for connecting with the lifting beam below. The lifting ropes 4 are used to connect the crane, the balance beam 3, and the steel frame 1 to each other to achieve lifting, thereby improving the safety of lifting, protecting the integrity of the box panels, and increasing the survival rate of trees.

[0030] Specifically, the steel structure frame 1 is a rectangular frame made of premium steel, measuring 4500*2600mm, with a thickness of 13mm, and the welds are full Class III welds. The steel structure frame 1 includes multiple crossbeams 11. These crossbeams 11 are connected by angle brackets 12, which are equipped with screws for fixing. The crossbeams 11 can be made of round or square steel tubing, depending on the actual application and load-bearing requirements.

[0031] Furthermore, an anti-slip layer is provided on the surface of the steel frame 1 to facilitate the placement of tree roots. This anti-slip layer can be made of rubber or a polyurethane coating, providing excellent anti-slip performance and wear resistance. The surface of the steel frame 1 is also coated with an anti-rust paint to extend its service life. The anti-rust paint can be an epoxy resin-based coating or a polyurethane-based coating, offering excellent corrosion resistance and adhesion.

[0032] The lifting rope 4 connected to the balance beam 3 is adjustable, and it has four lifting holes 5 at different positions. The rope 4 is adjusted by connecting it to different lifting holes 5. This allows for flexible adjustment of the connection point of the rope 4 according to the weight and center of gravity of the tree, ensuring the balance of the lifting operation.

[0033] A wear-resistant layer is provided on the wall of the lifting hole 5 to further prevent the lifting rope 4 from breaking due to excessive wear during connection. The wear-resistant layer can be made of hard alloy material or ceramic coating, which has excellent wear resistance and impact resistance.

[0034] The lifting rope 4 consists of an upper section connecting to the crane and the balance beam 3, and a lower section connecting to the balance beam 3 and the steel frame 1. The length ratio of the upper to lower sections is 1:3 to 1:4. This design can reasonably distribute the force during the lifting process and avoid excessive local stress that could cause the lifting rope 4 to break. The material of the lifting rope 4 can be either high-strength steel wire rope or nylon rope, depending on the actual usage scenario and load-bearing requirements.

[0035] Working Principle: This utility model designs a large-size box panel lifting and unloading auxiliary device. Through the rational combination of a steel structure frame 1, reinforcing ribs 2, a balance beam 3, and lifting ropes 4, it achieves stable lifting of large-size box panels. The steel structure frame 1 provides an overall support structure, ensuring the stable placement of the box panels; the crossbeam 11 and reinforcing ribs 2 enhance the rigidity of the structure, preventing deformation of the box panels during lifting; the adjustable length design of the balance beam 3 makes the lifting process more flexible and controllable; the reasonable length ratio of the lifting ropes 4 distributes the force during the lifting process, avoiding excessive local stress that could lead to damage. The overall solution not only improves the safety of lifting but also effectively protects the integrity of the box panels and the safety of the tree root system, providing a reliable guarantee for the survival of the trees.

[0036] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
