[0015] Reference Figures 1 to 2 An anti-collision device includes a main plate 1, a swing plate 2, a lifting eye bolt and nut assembly 5, a counterweight 8, a limit switch 9, a swing plate stop bar 11, and other auxiliary components. The main plate 1 serves as a support structure. The swing plate 2 is connected to the main plate 1 via a rotating shaft 10 and can rotate around the shaft. The counterweight 8 is connected to the swing plate 2 via a rope or chain 6. The limit switch 9 is installed on the main plate 1 to detect the position of the swing plate 2. The swing plate stop bar 11 passes through the main plate 1 to limit the range of motion of the swing plate 2.

[0016] The main body plate 1 is the core supporting component of the entire device. It is made of high-strength metal materials, such as aluminum alloy or stainless steel, and its thickness is designed to be between 8mm and 15mm according to actual load-bearing requirements to ensure rigidity and stability. The surface of the main body plate 1 is precision-machined and has multiple holes to meet the installation requirements of various components and allow for flexible adjustment. In practical applications, the upper part of the main body plate 1 extends outwards to accommodate the equipment frame for installation. Specifically, it is installed on the equipment frame using bolts or other fixing methods, providing a stable support foundation. Furthermore, the main body plate 1 also provides installation positions for the limit switch 9 and the swing plate stop 11, ensuring the compactness and functionality of the overall structure.

[0017] The main plate 1 is connected to the clamping plate 3 via clamping bolt assembly 4, forming a placement space for the swing plate 2 between the main plate 1 and the clamping plate 3. The main plate 1 and the clamping plate 3 are connected by clamping bolt assembly 4, which is respectively located on the upper and lower sides of the swing plate 2 to limit the vertical position of the swing plate 2. At the same time, both the main plate 1 and the clamping plate 3 have mounting holes for the swing plate stop rod 11 to be inserted. The swing plate stop rod 11 is installed on the swing plate 2. After installation, the swing plate stop rod 11 is inserted into the mounting holes of the main plate 1 and the clamping plate 3. Similarly, in order to facilitate installation with the equipment frame, multiple holes are provided on the clamping plate 3, which are specifically installed on the equipment frame by bolts or other fixing methods to provide a stable support foundation.

[0018] The swing plate 2 is a component that can rotate around an axis, and its shape and size are customized according to the application scenario. The swing plate 2 is rotatably mounted between the main body plate 1 and the clamping plate 3, and is installed via a rotating shaft 10. The specific connection method is as follows: a through hole is opened at one end of the swing plate 2, and the rotating shaft 10 is passed through the through hole and aligned with the corresponding hole on the main body plate 1 and the clamping plate 3. This connection method allows the swing plate 2 to swing freely within a certain range while ensuring its stability during movement. The range of motion of the swing plate 2 is limited by the swing plate stop rod 11, which is fixed to the swing plate 2 by screws or welding. Its length and position are designed according to the maximum allowable swing angle of the swing plate 2, specifically set according to the diameter of the opening, to avoid damage caused by collision.

[0019] The weight 8 is an object with a certain weight, used to use gravity to hold the pendulum 2 in a specific position or to generate a specific motion trajectory. The weight 8 can be designed to be cylindrical or rectangular, and is made of cast iron or steel. Its weight ranges from 1 kg to 20 kg, with the specific value adjusted according to the size of the pendulum 2 and the application scenario. For example, an industrial production line may require a weight of 3 kg to 5 kg. The weight 8 is connected to the pendulum 2 by a rope or chain 6. One end of the rope or chain 6 is fixed to the bottom of the pendulum 2, and the other end is connected to the weight 8 by a hook or other connector.

[0020] To facilitate installation with the counterweight body 8, a lifting eye screw 7 is also provided on the counterweight body 8 for connection with a rope or chain 6.

[0021] The limit switch 9 is mounted on the main body plate 1 and is used to detect the position or movement state of the swing plate 2. The model of the limit switch 9 can be selected according to actual needs, such as a mechanical limit switch or a photoelectric limit switch. During installation, the limit switch 9 is connected to the main body plate 1 through a connector or adjustment component. The connector or adjustment component is designed as an adjustable structure, such as a threaded rod or a slide rail, to optimize the installation position and sensitivity of the limit switch 9. To facilitate the practical use of the limit switch 9, a side top plate 21 extends outward from the swing plate 2. The side top plate 21 is positioned above the switching position of the limit switch 9, i.e., within the swing angle range of the swing plate 2. When the swing plate 2 reaches a specific angle or position due to external force, it will touch the limit switch 9, triggering a corresponding electrical signal or mechanical action, thereby realizing real-time monitoring and control of the movement state of the swing plate 2.

[0022] The working principle of this device is as follows: S1, the gravity provided by the counterweight 8 keeps the pendulum 2 in a specific position or produces a specific motion trajectory. For example, in the initial state, the weight of the counterweight 8 keeps the pendulum 2 in a vertical position, at which time the center of gravity of the pendulum 2 is aligned with the axis of the eye bolt and nut assembly 5, forming a balanced state. S2, when an external force is applied to the pendulum 2, the pendulum 2 will swing and achieve flexible rotation through the eye bolt and nut assembly 5. For example, in an industrial automated production line, when material hits the pendulum 2, the pendulum 2 will rotate around the axis of the rotating shaft 10, and the swing angle depends on the magnitude and direction of the external force. S3, the range of motion of the pendulum 2 is limited by the pendulum stop bar 11 to ensure that it moves within a safe range and prevent damage to the limit switch 9. For example, when the pendulum 2 swings to one side beyond the maximum allowable angle, the pendulum stop bar 11 will stop it from continuing to move, avoiding excessive swing that could damage the device or cause malfunction. S4 When the swing plate 2 reaches a specific angle or position, it will touch the limit switch 9, triggering the corresponding signal or action, disconnecting the hoisting system circuit, stopping the hook from rising, and ensuring safety.

[0023] The advantages of this invention are that its structure is simple, easy to manufacture and assemble, and the design and installation of each component are precisely calculated to ensure the stability and durability of the device under various working conditions. By adjusting parameters such as the weight of the counterweight and the position of the limit switch, the device can adapt to the needs of various application scenarios. Furthermore, the device adopts a modular design, facilitating disassembly, replacement, and maintenance, thereby reducing maintenance costs.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
