[0002] A winch, also known as a winch, is a small and light lifting equipment, mainly used for lifting or dragging materials. It lifts or pulls heavy objects by winding a wire rope or chain around a drum. It can not only lift vertically, but also drag horizontally or tilted. There are three main types of winches: manual, electric and hydraulic. Currently, electric winches dominate. It uses an electric motor as a power source, and the drive device rotates the drum. It can be used alone, but it is also an important component of mechanical equipment such as lifting, road construction and mine hoisting. Due to its simple operation, large amount of rope winding and convenient relocation, winches are widely used in construction, water conservancy projects, forestry, mining, docks and other fields.

[0003] However, the process of adjusting the outlet line of the winch is relatively cumbersome. It involves multiple steps such as disassembly, measurement, adjustment, and installation, which need to be performed in a specific order, and each step requires precise operation. Therefore, this task requires high experience and skills of the operator. In addition, the winch usually works in harsh environments such as high temperature, high humidity, and dust. These factors may not only damage its mechanical components and affect the accuracy and stability of the outlet line adjustment, but also interfere with the operator's work, further increasing the difficulty of the outlet line adjustment.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 - Figure 5 As shown, a winch mainly includes the following parts: a base 1 is used as the basic structure of the entire winch, and a rotating base 2 is connected to its side through a hinge device. A housing 3 and a driving transmission device 4 are installed on the side of the end face of the base 1, and a through groove 6 facing the winch drum 5 is also opened on the end face; the housing 3 is divided into an upper housing and a lower housing, and the two are fixed by bolts and nuts, and a sealing strip is provided at the connection to ensure its air tightness. The housing 3 and the driving transmission device 4 are both installed on the side of the end face of the base 1; the driving transmission device 4 includes a transmission gear, a servo motor and a reducer. The output end of the servo motor is connected to the reducer, and the output end of the reducer is connected to the winch drum 5 through a transmission gear. A bearing is provided between the transmission gear, the winch drum 5 and the housing 3 to ensure smooth rotation; the winch drum 5 is connected to the driving transmission device 4 and is the main working part of the winch.

[0024] The end surface of the rotating seat 2 is provided with a slide groove 7, and a plurality of through holes 10 are evenly distributed. These through holes 10 are used to insert fasteners 11 to fix the bracket 8. The connection between the rotating seat 2 and the base 1 adopts a semicircular design, and a notch is provided at the hinge device; the fastener 11 includes bolts, nuts and washers, which are used to fix the bracket 8 through the through hole 10; the bracket 8 is mounted with a roller 9 for supporting and guiding the winding of wire or other objects; the support frame 12 is mounted on both sides of the lower end of the base 1, and its cross section is in a "T" shape, and the lower end is an inclined surface. The support frame 12 is used to fix the electric push rod 13 and is connected to the base 1 by bolts; the telescopic end of the electric push rod 13 is arranged opposite to the rotating seat 2, and is fixed to the inclined surface of the support frame 12 by bolts. A rubber pad is provided at the connection between the electric push rod 13 and the support frame 12 to reduce vibration and noise; overall, this winch is reasonably designed and compact in structure, and the angle of the rotating seat 2 can be easily adjusted by the telescopic electric push rod 13 to meet different work requirements. At the same time, the sealing design of the housing 3 also effectively protects the internal transmission device from the influence of the external environment.

[0025] Working process: The rotating seat 2 is connected to the base 1 through a hinge device, so that it can rotate freely within a certain range. When the electric push rod 13 is extended and retracted, it will push the rotating seat 2 to rotate around the hinge device, thereby adjusting the angle of the rotating seat 2. The end face of the rotating seat 2 is provided with a slide groove 7, and the bracket 8 is fixed to the rotating seat 2 by a fastener 11, and can slide in the slide groove 7 to achieve fine adjustment of the position. The drum 9 installed on the bracket 8 is used to support and guide the winding of wire or other objects. When the hoist drum 5 rotates, the wire or other objects wound on the drum 9 will also move accordingly.

[0026] The electric push rod 13 is fixed to the inclined surface of the support frame 12 by bolts, and its telescopic end is arranged opposite to the rotating seat 2. When the electric push rod 13 is extended and retracted, it will push the rotating seat 2 to rotate around the hinge device, thereby adjusting the angle of the rotating seat 2. This design allows the winch to adapt to different working requirements, such as adjusting the winding angle, tension, etc. of wire or other objects. At the same time, since the rubber pad is provided at the connection between the electric push rod 13 and the support frame 12, vibration and noise can be reduced and working stability can be improved; according to work requirements, the angle of the rotating seat 2 is adjusted by the extension of the electric push rod 13, so that the roller 9 on the bracket 8 reaches a suitable winding position; the servo motor is started, and the winding of the wire or other objects is realized through the linkage of the transmission gear, the reducer and the hoist drum 5; during the winding process, the winding angle and tension of the wire or other objects can be fine-tuned by adjusting the extension of the electric push rod 13 and the position of the bracket 8 in the slide 7; when the work is completed, the rotating seat 2 is reset by the extension of the electric push rod 13 to prepare for the next work; this winch has a reasonable design and a compact structure. Through the mutual cooperation of the electric push rod 13 and the rotating seat 2, the winding angle and tension can be easily adjusted to meet different work requirements. At the same time, the sealing design of the housing 3 also effectively protects the internal transmission device from the influence of the external environment, and improves the service life and stability of the equipment.
