[0002] Rail cranes are material handling equipment widely used in factories, mines, ports, shopping malls, and warehouses, primarily for lifting, transporting, and loading / unloading heavy objects. With the continuous improvement of industrial automation and intelligence, the requirements for rail cranes in terms of operating efficiency, safety control, and intelligent management are also increasing. Traditional rail cranes typically consist of an electric hoist or winch, a drive mechanism, a driven mechanism, and a control system, driven by a disc motor to achieve movement and lifting operations along the rails.

[0052] In a preferred embodiment of the present invention, two connecting mechanisms are provided;

[0053] The connecting mechanism includes two connecting bushings 14, two slotted hexagonal nuts 38, and a lifting beam 35. One connecting bushing 14 is connected to the left side plate 12, and the other connecting bushing 14 is connected to the right side plate 4.

[0054] A retaining ring 28 connects the two lifting beams 35.

[0055] In a preferred embodiment of the present invention, a thin adjusting shim 37 and a cotter pin 16 are connected to the slotted hexagonal nut 38, and a thick adjusting shim 13 is connected to the connecting bushing 14.

[0056] In a preferred embodiment of the present invention, both the left side plate 12 and the right side plate 4 are connected to a safety plate 7. Example 1:

[0057] The electrical box mechanism includes an electrical box 1, hexagonal bolts 2, a contactor 3, a right side plate 4, an electrical unit 36, and a connecting plate 39. The electrical box 1 houses the electrical control components, providing protection and insulation to ensure the electrical safety and stable operation of the system. Hexagonal bolts 2 serve as a fixing connection, reliably mounting the electrical box 1 onto the right side plate 4 to ensure structural stability. The contactor 3 acts as a circuit switch control element, controlling the start, stop, and commutation of the disc motor 20.

[0059] The driven traveling mechanism includes a driven wheel 5, a limit pin 29, a flat washer 30, a hexagonal bolt 31, a rolling bushing 32, a connecting plate 33, and a rolling bearing 34. Figure 10 As shown, the driven wheel 5 abuts against the rail, bearing the rail load and rotating with the driving mechanism to achieve smooth movement. The limiting pin 29 serves to limit and guide, preventing the driven wheel 5 from derailing and restricting offset. By adjusting the position of the limiting pin 29 on the oblique strip hole 18 beforehand, and then fixing it in place using hexagonal bolts 31, the rolling bushing 32 is brought close to or abuts against the bottom wall of the rail, thus forming a clamping structure and improving the stability of the driven wheel 5. The flat washer 30 distributes the bolt connection pressure, preventing loosening and enhancing assembly reliability. The connecting plate 33 connects the rolling bushing 32 to the limiting pin 29. The rolling bearing 34 ensures smooth rotation of the rolling bushing 32, reducing energy consumption.

[0060] The driven walking mechanism has a compact structure. The combination design of the rolling bushing 32 and the rolling bearing 34 makes the wheel rotate smoothly, with low noise and long service life. The driven wheel 5, together with the rolling bushing 32, can effectively prevent the driven wheel 5 from derailing and ensure stable walking.

[0061] The drive mechanism includes an output gear 11, a left side plate 12, a reduction gearbox 15, a disc motor 20, and hex socket head cap screws 19. The disc motor 20 provides the main driving force and achieves stepless speed regulation through a control system. The hex socket head cap screws 19 secure the disc motor 20 and the reduction gearbox 15, ensuring coaxial accuracy of power transmission. The reduction gearbox 15 reduces the speed of the disc motor 20, increases the output torque, and improves drive efficiency. The output gear 11 meshes with a toothed drive wheel 17, transmitting power to the toothed drive wheel 17 of the active walking mechanism. The left side plate 12 supports and secures the reduction gearbox 15.

[0062] The drive mechanism features a compact structure and high transmission efficiency. The disc motor 20 provides stable driving force and can achieve stepless speed regulation. The hex bolts 19 ensure that the disc motor 20 and the gearbox 15 are coaxially fixed, ensuring the accuracy of power transmission.

The left side plate 12 provides solid support for the whole system, making the drive system run smoothly, with low noise, high transmission efficiency, and convenient maintenance, significantly improving the reliability and power performance of the crane.

[0063] The active walking mechanism includes a connecting bearing 6, a retaining ring 8, a bearing cage 9, bearing rings 10, and a toothed drive wheel 17. The connecting bearing 6 supports the toothed drive wheel 17 and ensures smooth rotation. The retaining ring 8 is used to fix the position of the connecting bearing 6 and prevent axial slippage. The bearing cage 9 separates and guides the rolling elements, preventing them from colliding with each other, ensuring even load distribution, smooth operation of the connecting bearing 6, and extending its lifespan. The bearing rings 10, serving as the inner and outer rings of the connecting bearing 6, bear the load and ensure accuracy. The toothed drive wheel 17 meshes with the output gear 11 and abuts against the track, realizing power transmission and active walking; it is the main active walking component of this device.

[0064] The active walking mechanism has a precise structure and reliable operation. It adopts a dual-wheel parallel design, which makes the load distribution uniform and the operation more stable, improving the crane's movement accuracy and anti-deviation ability. The connecting bearing 6 provides stable support for the toothed drive wheel 17 and ensures smooth rotation. The bearing ring 10 bears and distributes the load to maintain accuracy. The toothed drive wheel 17 meshes precisely with the output gear 11 and abuts against the track to achieve efficient power transmission. The overall structure has smooth transmission, high efficiency and strong durability.

[0065] The connecting mechanism includes a connecting bushing 14, a slotted hexagonal nut 38, a lifting beam 35, a thick adjusting shim 13, a thin adjusting shim 37, a cotter pin 16, and a retaining ring 28. The connecting bushing 14 connects the electrical box mechanism and the drive mechanism and absorbs vibration. The slotted hexagonal nut 38, in conjunction with the cotter pin 16, prevents the connecting bushing 14 from loosening, improving safety. The lifting beam 35, as the core connecting and load-bearing component, is used to attach the retaining ring 28 and bear the load of the lifting device and goods. The thick adjusting shims 13 and thin adjusting shims 37 are used for fine-tuning the spacing and level, ensuring installation accuracy. The retaining ring 28 improves the overall stability of the lifting beam 35 connection, prevents deformation, and most importantly, is used to connect the electric hoist. The specific structure and shape of the retaining ring 28 can be designed according to actual conditions, for example... Figure 1 and Figure 2 As shown, no specific limitation is made here. The cotter pin 16 is used to lock the slotted hexagonal nut 38 in place to prevent it from loosening.

[0066] The connecting mechanism is robust and has excellent seismic resistance. The connecting bushing 14 ensures reliable connection and vibration reduction between the electrical box mechanism and the drive mechanism. The slotted hexagonal nut 38 and the cotter pin 16 form an anti-loosening structure to ensure long-term safe operation. The lifting beam 35 and the fixing ring 28 jointly bear the main load, with uniform force transmission and strong load-bearing capacity, preventing structural deformation. The thick adjusting shim 13 and the thin adjusting shim 37 can precisely adjust the spacing and level, improving installation accuracy. The overall design combines anti-loosening, anti-vibration, and high-precision characteristics, making the whole machine stable, safe, and reliable, with good versatility and durability.

[0067] Safety plate 7 is used to protect the toothed drive wheel 17 and driven wheel 5. Both the toothed drive wheel 17 and driven wheel 5 are located on the outer traveling part of the device and are exposed and rapidly rotating moving parts, which are highly susceptible to the influence of foreign objects, dust, or accidental contact. Installing safety plate 7 can effectively prevent foreign objects from getting caught in the gears or wheels, avoiding jamming, wear, or safety accidents. At the same time, it can also prevent operators from accidentally contacting rotating parts, thereby improving the safety and reliability of the entire machine operation.

[0068] In a preferred embodiment of the present invention, a stator 21 is fixedly connected to the inner wall of the disc motor 20, and a rotor 22, an internal gear ring 25, and a reduction gear 27 are rotatably connected to the inner wall of the disc motor 20. A heat-conducting ring 23 is fixedly connected to the stator 21, and a semiconductor cooling chip 24 is fixedly connected to the internal gear ring 25. The cold end face of the semiconductor cooling chip 24 abuts against the smooth surface of the heat-conducting ring 23. A thermal expansion member 26 is fixedly connected to the hot end face of the semiconductor cooling chip 24, and a ball 40 is rolledly connected to the telescopic end of the thermal expansion member 26. The reduction gear 27 meshes with the internal gear ring 25. A friction ring 44 is fixedly connected to the rotor 22, and a slip ring 41 is slidably connected to the inner wall of the disc motor 20. The slip ring 41 is connected to the inner wall of the disc motor 20 through a spring 43. A friction gear 42 is rotatably connected to the slip ring 41, and the friction gear 42 meshes with the reduction gear 27. The friction gear 42 has a friction surface, and the outer diameter of the friction gear 42 is smaller than the outer diameter of the reduction gear 27. The slip ring 41 has an inclined surface.

[0069] In a preferred embodiment of the present invention, a temperature sensor is connected to the stator 21. Example 2:

[0070] The stator 21 is the primary heat-generating component within the disc motor 20. Cooling the stator 21 significantly reduces the heat within the disc motor 20. When the temperature sensor detects that the stator 21 temperature exceeds a threshold, the control system controls the cold end of the thermoelectric cooler 24 to cool the heat-conducting ring 23 and the stator 21. The hot end of the thermoelectric cooler 24 heats up, causing the expansion joint 26 to expand and elongate. This causes the inclined surfaces of the ball 40 and the slip ring 41 to abut against each other, pushing the slip ring 41 against the spring force 43 and moving it towards the friction ring 44. This causes the friction surface on the friction gear 42 to abut against the friction ring 44. When the friction ring 44 rotates, it drives the friction gear 42 to rotate through friction. The friction gear 42 then drives the reduction gear 27, the internal gear ring 25, and the thermoelectric cooler 24 to rotate, thus increasing the friction... Gear 42 rotates rapidly. After being reduced in speed by reduction gear 27 and internal gear ring 25, the thermoelectric cooler 24 rotates slowly. During rotation, the thermoelectric cooler 24 cools multiple locations on the heat-conducting ring 23, thereby cooling multiple locations on the stator 21, improving the uniformity of cooling and preventing local overheating of the stator 21. Since the sidewall of the stator 21 is uneven, in this design, the thermoelectric cooler 24 does not directly contact the stator 21, but conducts heat and cold through the heat-conducting ring 23. The contact between the cold end face of the thermoelectric cooler 24 and the smooth surface of the heat-conducting ring 23 not only improves the heat transfer efficiency, but also reduces frictional damage to the thermoelectric cooler 24.

[0071] When the temperature sensor detects that the temperature of stator 21 is lower than the threshold value 2, the control system controls the semiconductor cooling chip 24 to stop working. The hot end of the semiconductor cooling chip 24 gradually cools down, the expansion end of the thermal expansion member 26 cools down and contracts, the ball 40 releases its contact with the inclined surface of the slip ring 41, the slip ring 41 moves back to its original position under the elastic force of the spring 43, and the friction gear 42 releases its contact with the friction ring 44, thereby reducing the wear and tear of the friction gear 42, the reduction gear 27, the internal gear ring 25, and the semiconductor cooling chip 24, and extending the service life of the components.

[0072] The beneficial effects of this embodiment are as follows:

[0073] Automatic temperature control and dynamic heat dissipation adjustment are achieved. The temperature sensor set on the stator 21 can detect the operating temperature in real time. The control system automatically starts the semiconductor cooling chip 24. The cold end face cools the heat conduction ring 23 and the stator 21 to achieve rapid cooling and effectively prevent the stator 21 from overheating, which can lead to insulation aging and performance degradation.

[0074] The heat-conducting ring 23 and the semiconductor cooling chip 24 work together to cool the temperature. The heat-conducting ring 23 and the semiconductor cooling chip 24 are closely fitted to form an efficient heat transfer interface. The cold end face contacts the smooth surface of the heat-conducting ring 23 to improve the cooling efficiency and avoid damage to the cooling chip caused by friction. At the same time, it can achieve uniform heat dissipation in multiple areas of the stator 21 and improve the temperature distribution uniformity.

[0075] The thermal expansion component 26 and the ball 40 are adaptively linked. When the semiconductor cooling chip 24 generates heat, the thermal expansion component 26 is heated and expands. It pushes the slip ring 41 to move along the inclined plane through the ball 40, so that the friction gear 42 and the friction ring 44 are automatically engaged. This converts thermal expansion into mechanical linkage and realizes automatic switching of friction drive mode without manual intervention or additional electrical components, thus saving energy.

[0076] The friction gear 42 meshes with the reduction gear 27 and the internal gear ring 25 to form a multi-stage reduction mechanism, which ensures that the semiconductor cooling chip 24 rotates at a low speed, so as to slowly and uniformly cool the heat conduction ring 23, avoid local overcooling or thermal shock, and significantly improve the thermal stability and cooling uniformity of the system.

[0077] The return mechanism of slip ring 41 and spring 43 improves reliability. Slip ring 41 is connected to the inner wall of disc motor 20 through spring 43. When the temperature drops below the threshold, spring 43 automatically returns to its original position, causing friction gear 42 to separate from friction ring 44, stopping transmission, reducing wear and energy consumption of various components, and extending the service life of friction gear 42, reduction gear 27, internal gear ring 25 and semiconductor cooling chip 24.

[0078] The system boasts outstanding overall intelligence and energy-saving performance. Through temperature sensors, control systems, and thermo-mechanical coupling design, it achieves automatic detection and heat dissipation management of the internal heat of the disc motor 20, taking into account energy saving, durability, and intelligent control. The system can automatically switch cooling modes under specific working conditions, improving the safety, lifespan, and energy efficiency of the intelligent rail crane.
