Its structure includes a base, support frame, bearing housing, motor, transmission box, connecting plate, support seat, locking device, handle, and roller. The upper surface of the base is welded to the bottom surface of the support frame. This device, an automatically lubricated safety winch specifically for bridge construction, features a roller. The left end face of the side plate is attached to the right end face of the support seat. Lubricating oil is injected into the inner cylinder through an oil pipe, and then the centrifugal force of the rotation causes the oil to be thrown out. The thrown-out oil is absorbed and discharged by oil-guiding cotton, automatically lubricating the cable and ensuring smooth winch operation.

[0004] Traditional winch transmission devices generally suffer from problems such as low transmission efficiency, high energy consumption, and high maintenance costs, making it difficult to meet the demands of modern industry for high efficiency, energy saving, and environmental protection.

[0005] Therefore, a winch transmission device is proposed to address the above problems. Utility Model Content

[0024] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 3 As shown below, see details:

[0025] In a preferred embodiment, the positioning assembly includes a fixed connecting plate 3, which is located above the right end of the gantry crane beam 1. The gantry crane beam 1 and the winch base 2 are positioned using the fixed connecting plate 3. Furthermore, the core component of the positioning assembly is the fixed connecting plate 3, which is precisely installed above the right end of the gantry crane beam 1 to form a stable support point. Through precise manufacturing and installation processes, the fixed connecting plate 3 ensures that the gantry crane beam 1 and the winch base 2 can be accurately positioned in both the horizontal and vertical directions, improving the stability of the entire hoisting system and providing strong support for the precise operation of the winch.

[0026] In a preferred embodiment, the connecting assembly includes a movable connecting plate 4, which is detachably installed on the side of the gantry crane beam 1. The gantry crane beam 1 and the winch base 2 are connected by the movable connecting plate 4, and bolts are detachably installed on the top of the movable connecting plate 4. Furthermore, the connecting assembly is composed of the movable connecting plate 4, which is designed to be flexibly and detachably installed on the side of the gantry crane beam 1, providing great convenience for the connection between the gantry crane beam 1 and the winch base. The movable connecting plate 4 is firmly connected to the gantry crane beam 1 and the winch base 2 by the detachable bolts on its top, which not only ensures the stability of the connection, but also facilitates quick disassembly and reinstallation when needed, improving the flexibility and maintainability of the entire hoisting system. The fixed connecting plate 3 is provided with a vertically downward positioning boss, and the gantry crane beam 1 has a groove with an interference fit with the positioning boss at the corresponding position. The movable connecting plate 4 is installed on the side of the gantry crane beam 1 by detachable bolts, and its top extends to the bottom of the winch base 2 to form a support structure.

[0027] In a preferred embodiment, the reducer 9 is located directly above the winch base 2. When the brake 7 rotates with the first rotating shaft 6, the brake 7 and the reducer 9 are linked. Furthermore, the reducer 9 is arranged directly above the winch base 2 and is closely connected to the winch's transmission system. When the motor 5 drives the first rotating shaft 6 to rotate, the brake 7 rotates synchronously and is seamlessly linked with the reducer 9 through a mechanical structure, ensuring the continuity and stability of power transmission. At the same time, the timely intervention of the brake 7 can effectively control the operating state of the winch and improve the safety and controllability of the operation.

[0028] In a preferred embodiment, a fixed bearing seat 13 is provided on one side of the drum 12. The fixed bearing seat 13 is located directly above the winch base 2 and is positioned with the winch base 2 using bolts. Furthermore, the fixed bearing seat 13 is firmly installed on one side of the drum 12. The fixed bearing seat 13 sits steadily on the winch base 2, forming a stable support for the rotation of the drum 12. In order to ensure the precise positioning of the drum 12 during high-speed rotation, the fixed bearing seat 13 is precisely positioned and connected to the winch base 2 with high-strength bolts. This not only improves the smoothness of the drum 12's operation but also greatly enhances the structural strength and stability of the entire hoisting system.

[0029] In a preferred embodiment, a pin body 14 is provided above the winch base 2, and there are multiple pin bodies 14. Furthermore, multiple pin bodies 14 are arranged above the winch base 2. These pin bodies 14 are evenly distributed, which not only enhances the structural stability of the winch base, but also facilitates quick connection with other components. The design of multiple pin bodies 14 makes the entire hoisting system more flexible and efficient in assembly, adjustment and disassembly, while also improving the safety and reliability of the operation.

[0030] The working process of this utility model is as follows: When in use, firstly, the fixed connecting plate 3 in the positioning component is used to accurately position the winch base 2 above the right end of the gantry crane beam 1. The fixed connecting plate 3 ensures the stability of the winch base 2 in the horizontal and vertical directions.

[0031] Next, the gantry crane beam 1 is connected to the winch base 2 via the movable connecting plate 4 in the connecting assembly. The bolts on the movable connecting plate 4 ensure a secure connection between the two while facilitating disassembly and reinstallation.

[0032] Above the winch base 2, start the motor 5. The output of the motor 5 drives the first rotating shaft 6 to rotate, which in turn drives the brake 7 to rotate. The brake 7 is linked with the reducer 9 through the second rotating shaft 8 to ensure the continuity and stability of power transmission.

[0033] After the reducer 9 lowers the speed and increases the torque, it drives the drum 12 to rotate via the third rotating shaft 11. The rotation of the drum 12 enables the winding and unwinding of the wire rope, completing the hoisting and transportation of goods.

[0034] During the hoisting process, the tension load sensor 10 monitors and provides feedback on the hoisting load information in real time to ensure operational safety.

[0035] When it is necessary to adjust or disassemble the winch, the winch base can be quickly fixed or released by loosening the bolts on the movable connecting plate 4 and using the multiple pin bodies 14 above the winch base 2, so as to achieve flexible adjustment of the winch.
