[0002] As a crucial component of the hoist, the tail pulley's performance directly impacts the hoist's operational stability and service life. Heat treatment, especially quenching, is a key process in the manufacturing of the tail pulley, significantly improving its hardness, wear resistance, and strength. However, current traditional tail pulley quenching processes largely rely on manual labor. Operators must individually place the tail pulleys into heating equipment to a suitable temperature, then quickly transfer them to a quenching medium for cooling. This process is labor-intensive and requires substantial manpower. Furthermore, manual operation poses safety hazards, as operators are susceptible to burns from the high-temperature equipment or injuries from splashes of the quenching medium. Utility Model Content

[0018] This utility model discloses a heat treatment device for the tail wheel of a hoist.

The heating coil 4 is disposed on one side of the high-frequency heater 1. A water tank 2 is disposed on one side of the high-frequency heater 1 and below the heating coil 4. A movable plate 3 is disposed inside the water tank 2. Multiple through holes are opened on the surface of the movable plate 3 to facilitate the passage of coolant. Two pairs of support plates 14 are fixedly disposed on the upper surface of the movable plate 3. Multiple guide wheels are rotatably disposed between two adjacent support plates 14 from front to back. Limiting mechanisms are disposed on the front and rear sides of the movable plate 3. A transmission mechanism for moving the movable plate 3 is disposed inside the water tank 2.

[0020] Reference Figures 1-4 The limiting mechanism includes a baffle 12, an iron plate 15 is provided below the movable plate 3, two baffles 12 are abutted on the front and rear sides of the movable plate 3, the lower end of the baffle 12 is fixedly connected to the iron plate 15, and an electromagnet 18 is fixedly provided on the lower surface of the movable plate 3, and the electromagnet 18 is magnetically attracted to the iron plate 15.

[0021] Reference Figures 1-4The transmission mechanism includes a push rod 11 and a U-shaped plate 5. A bidirectional lead screw 6 is rotatably installed on the lower side of the interior of the water tank 2. Two U-shaped plates 5 are threaded onto one end of the corresponding bidirectional lead screw 6. The push rod 11 is located on the inner side of the U-shaped plate 5. Both ends of the push rod 11 are rotatably fitted with shaft pins 9. The two ends of the lower shaft pin 9 are rotatably connected to the inner wall of the corresponding U-shaped plate 5. Both ends of the upper shaft pin 9 are rotatably connected to connecting rods 10. The upper end of the connecting rod 10 is fixedly connected to the movable plate 3. A motor 8 is fixedly installed on one outer wall of the water tank 2. The output end of the motor 8 is fixedly connected to one end of the bidirectional lead screw 6. Slide rods 7 are arranged parallel to each other on both sides of the bidirectional lead screw 6. Both ends of the slide rods 7 are fixedly connected to the inner wall of the corresponding water tank 2. Both ends of the U-shaped plate 5 are movably fitted with the corresponding slide rods 7, so that the U-shaped plate 5 can slide stably.

[0022] Reference Figures 1-4 Two limiting rods 16 are fixedly installed on the lower surface of the movable plate 3. Both ends of the iron plate 15 are movably connected to the corresponding limiting rods 16. An anti-detachment block is fixedly installed at the lower end of the limiting rod 16, so that the iron plate 15 can slide stably. A spring 17 is movably connected to the rod wall of the limiting rod 16. Both ends of the spring 17 are fixedly connected to the corresponding iron plate 15 and the movable plate 3, respectively, so as to facilitate the iron plate 15 to move down and reset.

[0023] In this invention, during use, sufficient quenching coolant is first injected into the water tank 2. The tail wheel of the hoist to be quenched is placed between the guide wheels on the upper surface of the movable plate 3. At this time, the electromagnet 18 is energized and magnetically attracted to the iron plate 15. The iron plate 15 drives the baffle 12 to move upward. The two baffles 12 limit the tail wheel from the front and rear sides of the movable plate 3 to prevent the tail wheel from shifting. The high-frequency heater 1 is started. The high-frequency heater 1 generates a high-frequency magnetic field through the heating coil 4. Then, the motor 8 is started. The output end of the motor 8 drives the bidirectional lead screw 6 to rotate. Since the two U-shaped plates 5 are threadedly connected to the bidirectional lead screw 6 and movably connected to the slide rod 7, when the bidirectional lead screw 6 rotates, it drives the two U-shaped plates 5 to move towards each other along the slide rod 7. The U-shaped plates 5 drive the lower shaft pin 9 to move, causing the push rod 11 to rotate around the lower shaft pin 9 and tend to be vertical. The push rod 11 pushes the connecting rod 10 to move upward through the upper shaft pin 9. The connecting rod 10 drives the movable plate 3 and the tail wheel to rise synchronously until the tail wheel is completely inside the heating coil 4. On the side, motor 8 is turned off, and the high-frequency magnetic field induction heats the tail wheel. After reaching the preset quenching temperature, the heating is maintained for a preset time. After heating is completed, motor 8 is started in reverse, and the bidirectional lead screw 6 drives the two U-shaped plates 5 to move in opposite directions. The push rod 11 rotates towards the horizontal, and the connecting rod 10 drives the movable plate 3 and the heated tail wheel to descend. The tail wheel is gradually immersed in the coolant in the water tank 2 for quenching and cooling. After cooling for a preset time, motor 8 is started in the forward direction again, raising the movable plate 3 to the upper part of the water tank 2, so that the tail wheel is removed from the coolant. The power of electromagnet 18 is turned off, and the magnetic attraction between electromagnet 18 and iron plate 15 is released. Spring 17 releases its elastic force, pushing iron plate 15 to move downward along limit rod 16. Iron plate 15 drives baffle 12 to move downward, releasing the limit on the tail wheel. At this time, the tail wheel is pushed, and the tail wheel moves along the surface of movable plate 3 under the rolling action of guide wheel and is transported to the subsequent process, completing one fully automatic quenching process. The above steps are repeated to quench the tail wheel of the next hoist.

[0024] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
