Description

Technical Field

[0001] This utility model relates to the field of winch technology, specifically a marine lifting winch with anti-loosening function. Background Technology

[0002] A lifting winch is a mechanical device used for vertically or inclinedly lifting heavy objects. It is typically driven by an electric motor or internal combustion engine, and the lifting and lowering of goods is achieved by winding wire ropes or chains onto a drum. Winches are widely used in various applications such as construction, dock loading and unloading, and mine hoisting. However, existing lifting winches still have certain shortcomings, such as:

[0003] The application CN202320953618.4, entitled "A Lifting Winch for Construction," includes a fixed base plate with two sliding grooves on its upper surface. Two drive electric cylinders are fixedly connected to both sides of the fixed base plate, and drill column modules are fixedly connected to the four corners of the bottom surface of the fixed base plate. Lifting columns are movably fitted into the sliding grooves of the fixed base plate, and shaft holes are opened at the upper ends of the lifting columns.

[0021] 1. After the electric winch drum is hoisted, start the No. 1 motor. The No. 1 motor drives the shaft to rotate.
