The end of the wire rope 6 away from the winding roller 5 is fixedly connected to the outer surface of the outer casing 1.

[0023] Specifically, the cooperation between the guide slider 205 and the guide groove plays a role in guiding the movement of the threaded ring block 204, thereby improving the stability of the guiding movement of the threaded ring block 204 and the annular block 207.

[0025] Specifically, the cooperation between the threaded rod 203 and the threaded ring block 204 facilitates the driving and movement of the ring block 207, allowing the ring block 207 to change with the position of the wire rope 6, thus preventing the wire rope 6 from shifting significantly and playing a role in preventing deviation.

[0026] Please see Figures 1 to 7 The wire rope 6 passes through the annular block 207, which is fixedly connected to the oil reservoir 301. One end of the support rod 206 is fixedly connected to the threaded ring block 204, and the other end of the support rod 206 is fixedly connected to the outer surface of the oil reservoir 301.

[0027] Specifically, the sealing baffle 304 conveniently blocks the oil inlet, preventing external dust from entering the interior of the oil reservoir 301 and preventing the lubricating oil inside the oil reservoir 301 from being contaminated, thus facilitating the lubrication of the wire rope 6.

[0031] Specifically, the two semi-circular oil brushes 308 are closed to form a ring-shaped oil brush sleeve on the wire rope 6, which facilitates the application of lubricating oil to the wire rope 6. The cooperation between the locking block 408 and the locking groove improves the stability of the closure of the two semi-circular oil brushes 308.

[0032] Please see Figures 5 to 10 There are two semi-circular oil brushes 308. The sides of the two semi-circular oil brushes 308 abut against each other. The semi-circular oil brushes 308 abut against the outer surface of the wire rope 6. The locking block 408 is installed on one side of the semi-circular oil brush 308. A locking groove adapted to the locking block 408 is opened on one side of the semi-circular oil brush 308. The end of the locking block 408 is inserted into the inside of the locking groove.

[0033] Specifically, the stability of the semi-circular oil brush 308 is improved by the fit between the bolt 406 and the threaded hole.

[0034] Please see Figures 5 to 6 One end of the return spring 401 is installed inside the oil reservoir 301, and the other end of the return spring 401 is fixedly connected to the adjusting plate 402.

[0037] In use, this electric hoist addresses the pain points of traditional equipment, such as easy wire rope deviation and cumbersome lubrication and maintenance. With its core advantages of dynamic follow-up anti-deviation, closed-loop clean lubrication, and quick disassembly and maintenance, it is suitable for various industrial scenarios with specific requirements for lifting stability and maintenance efficiency. The electric hoist is connected to the lifting trolley of an external European-style crane for lifting heavy objects. During operation, the drive motor 7 rotates the winding roller 5, and one end of the wire rope 6 is wound around the winding roller 5, while the other end is fixed to the outer casing 1 for easy winding. Roller 5 winds up or unwinds the wire rope 6. Reducer 8 reduces speed and increases torque to suit operational needs, facilitating the lifting of heavy objects via the wire rope 6. An annular block 207 is fitted around the outside of the wire rope 6. Driven by the movement of the annular block 207, it moves with the position of the wire rope 6, preventing significant deviation and improving stability during lifting. As the annular block 207 moves, servo motor 202 drives the threaded rod 203 to rotate. The threaded rod 203 is connected to the threaded annular block 204, providing a guide. Block 205 slides along the length of the guide groove on the rectangular frame 201, causing the threaded ring block 204 to move along with the guide slider 205, support rod 206, and annular block 207. This allows the annular block 207 to move as the position of the wire rope 6 changes. When lubricating oil is added to lubricate the wire rope 6, the push block 306 is pushed downwards, causing the sealing baffle 304 to move along with the positioning slider 305. This causes the limit spring 303 to contract under force, allowing the positioning slider 305 to slide along the length of the positioning groove on the U-shaped plate 302. Move the sealing baffle 304 downward and away from the oil inlet. Add lubricating oil into the oil reservoir 301 through the oil inlet. Then release the push block 306. The elastic tension of the limit spring 303 causes the sealing baffle 304 to reset and block the oil inlet, preventing external dust from contaminating the lubricating oil in the oil reservoir 301. The lubricating oil in the oil reservoir 301 drips from the oil outlet pipe 307 to the semi-circular oil brush 308, making it convenient to apply lubricating oil to the wire rope 6 through the semi-circular oil brush 308, thus facilitating the lubrication of the wire rope 6.When the semi-circular oil brush 308 is disassembled and replaced after long-term wear, the bolt 406 is loosened to disengage it from the threaded hole in the oil reservoir 301 and the L-shaped plate 405. Then, the L-shaped plate 405 is moved, causing the limiting block 404, adjusting plate 402, and T-shaped slider 403 to move. This causes the return spring 401 to contract under force, guiding the T-shaped slider 403 to slide along the length of the T-shaped groove in the oil reservoir 301. Move the limiting block 404 away from the limiting groove on the positioning block 407, then move the two semi-circular oil brushes 308 downwards, causing the positioning block 407 to leave the positioning groove on the oil reservoir 301, making it easier to move the two semi-circular oil brushes 308 away from the oil reservoir 301. Then move the two semi-circular oil brushes 308 to both sides, causing the locking block 408 on one semi-circular oil brush 308 to leave the inside of the locking groove on the other semi-circular oil brush 308, making it easier for the semi-circular oil brush 308 to move away from the wire rope. 6. Facilitates the disassembly of the semi-ring oil brush 308; conversely, when installing a new semi-ring oil brush 308, move the two semi-ring oil brushes 308 to the outside of the wire rope 6, so that the locking block 408 is inserted into the inside of the locking groove, so that the two semi-ring oil brushes 308 are closed into a ring oil brush. Then move the semi-ring oil brush 308 upward so that the end of the positioning block 407 enters the inside of the positioning groove. When the limiting groove on the positioning block 407 is aligned with the limiting block 404, the L-shaped plate 405 is released. Through the elastic tension of the return spring 401, the end of the limiting block 404 is inserted into the inside of the limiting groove. When the end of the limiting block 404 reaches the end of the limiting groove, the threaded hole on the L-shaped plate 405 is aligned with the threaded hole on the oil reservoir 301. Tighten the bolt 406 so that the bolt 406 enters the inside of the threaded hole, which facilitates the restriction of the position of the positioning block 407, improves the stability of the installation of the semi-ring oil brush 308, and improves its practicality. ;
