Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, specifically to a windproof ground anchor device for gantry cranes. Background Technology

[0002] A gantry crane is a type of lifting equipment widely used in industry, warehousing, and logistics. It mainly consists of a gantry structure, lifting mechanism, traveling mechanism, and control system. Gantry cranes are typically used for lifting, handling, and stacking heavy objects within a fixed area. Ground anchors are a crucial component of gantry cranes, primarily used to secure the crane and prevent it from moving or tipping over during lifting. During lifting, the crane may move due to the tension of the load or wind force. Ground anchors ensure stability by fixing the crane to the ground. When lifting heavy objects, the weight of the load may cause the crane to tip over; ground anchors provide additional support to prevent this. However, existing ground anchors are prone to failure or being blown out by the wind in windy conditions without protection, and their single-point fixation is ineffective and cannot guarantee a good restraining effect. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a windproof ground anchor device for a gantry crane, comprising a mounting base connected to the main body of the gantry crane, three ground anchor structures being mounted through the inner wall of the mounting base, the three ground anchor structures being arranged in a triangular pattern, and a windproof structure being mounted on the surface of the mounting base.

[0005] Preferably, the windproof structure includes a windproof cover, which is disposed on the surface of the mounting base. Connecting plates are symmetrically fixed to both sides of the windproof cover. Two first screws are installed through the inner wall of the connecting plates. The lower ends of the first screws are inserted into the mounting base and screwed in.

[0006] Preferably, the ground anchor structure includes a horizontal plate, a hollow anchor rod is fixedly mounted on the inner wall of the horizontal plate, four second screws are evenly penetrated through the surface of the horizontal plate, the lower ends of the four second screws are inserted into the mounting base and screwed in, a top rod is inserted into the upper end of the inner wall of the hollow anchor rod, a threaded section is fixedly mounted on the upper end of the top rod, the diameter of the threaded section is slightly larger than the top rod, and the threaded section is screwed into the inner wall of the hollow anchor rod, a plurality of insert rods are inserted through the inner wall of the hollow anchor rod, the inner end of the insert rod is set in a wedge shape, and the lower end of the top rod matches the inner end of the insert rod, and a locking block is fixedly mounted on the outer end of the insert rod, and the outer end of the locking block is a pointed tip.

[0007] Preferably, the upper end of the threaded section is fixedly fitted with a rotating rod assembly groove, and the inner wall of the rotating rod assembly groove can be used to insert a rotating rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: The installation base connects to the main body of the gantry crane, ensuring the stability of the gantry crane installation. Simultaneously, three sets of ground anchor structures fix the installation base, thereby securing the gantry crane. These three sets of ground anchor structures are arranged in a triangle, which provides natural stability and evenly distributes the force on the installation base, preventing tilting or movement in any direction. The triangular arrangement also effectively resists torsional forces, ensuring the installation base does not rotate under external force. Each ground anchor structure bears a relatively uniform force, preventing any single anchor structure from failing due to excessive stress. The windproof structure protects the ground anchor structures from wind damage, ensuring installation stability. The upper end of the windproof structure is sloped, facilitating wind direction guidance and reducing stress. It is convenient to use and highly practical. Attached Figure Description

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5This utility model provides a windproof ground anchor device for a gantry crane, including a mounting base 1, which is connected to the main body of the gantry crane. Three ground anchor structures 3 are installed through the inner wall of the mounting base 1, and the three ground anchor structures 3 are arranged in a triangle. A windproof structure 2 is installed on the surface of the mounting base 1.

[0017] The gantry crane body is connected to the mounting base 1, ensuring the stability of the gantry crane installation. Simultaneously, three sets of ground anchor structures 3 fix the mounting base 1, thus securing the gantry crane. These three sets of ground anchor structures are arranged in a triangle, which provides natural stability and evenly distributes the force on the mounting base 1, preventing it from tilting or moving in any direction. The triangular arrangement also effectively resists torsional forces, ensuring the mounting base 1 does not rotate under external forces. Each ground anchor structure 3 bears a relatively uniform force, preventing any single anchor structure 3 from failing due to excessive stress. The windproof structure 2 protects the ground anchor structures 3 from wind damage, ensuring their installation stability. The upper end of the windproof structure 2 is sloped, facilitating wind direction guidance, reducing stress, and making it convenient and practical.

[0018] The windproof structure 2 includes a windproof cover 21, which is placed on the surface of the mounting base 1. Connecting plates 22 are symmetrically fixed to both sides of the windproof cover 21. Two first screws 23 are installed through the inner wall of the connecting plates 22. The lower ends of the first screws 23 are inserted into the mounting base 1 and screwed in.

[0019] The upper end of the wind shield 21 is set as a slope. When the wind blows, it will guide the wind direction and make it blow upward, reducing the force on the wind shield 21. The wind shield 21 is fixed to the mounting base 1 by the connecting plates 22 on both sides and the first screw 23, which makes it easy to disassemble and maintain the equipment.

[0020] The ground anchor structure 3 includes a horizontal plate 31. A hollow anchor rod 36 is fixedly mounted on the inner wall of the horizontal plate 31. Four second screws 32 are evenly penetrated through the surface of the horizontal plate 31. The lower ends of the four second screws 32 are inserted into the mounting base 1 and screwed on. A top rod 33 is inserted into the upper end of the inner wall of the hollow anchor rod 36. A threaded section 34 is fixedly mounted on the upper end of the top rod 33. The diameter of the threaded section 34 is slightly larger than that of the top rod 33, and the threaded section 34 is screwed on the inner wall of the hollow anchor rod 36. Multiple insert rods 35 are inserted through the inner wall of the hollow anchor rod 36. The inner end of the insert rod 35 is set in a wedge shape, and the lower end of the top rod 33 matches the inner end of the insert rod 35. A locking block is fixedly mounted on the outer end of the insert rod 35, and the outer end of the locking block is a pointed tip.

[0021] When assembling the ground anchor structure 3, first insert the hollow anchor rod 36 into the ground, with the pre-drilled mounting holes for the anchor rod. Simultaneously, attach the horizontal plate 31 to the mounting base 1 and use the second screw 32 to thread through the horizontal plate 31 and connect it to the mounting base 1. Then, pour concrete into the pre-drilled mounting holes. After the concrete is filled, before it solidifies, insert the top rod 33 downwards and attach the threaded section 34 to the upper end of the hollow anchor rod 36. At this time, the top rod 33 will push out the hidden insert rods 35 and insert them into the unsolidified concrete, ensuring multi-directional contact and more stable anchor rod assembly. Then, rotate the threaded section 34 to screw it into the hollow anchor rod 36, completing the assembly.

[0022] The upper end of the threaded section 34 is fixedly fitted with a rotating rod mounting groove 4, and a rotating rod can be inserted into the inner wall of the rotating rod mounting groove 4.

[0023] The rotating rod assembly slot 4 facilitates the installation of the rotating rod, and the rotation of the threaded section 34 can be adjusted by the rotating rod.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
