Description

[0002] To prevent electric shock accidents during lifting operations, the electrical control system of monorail cranes, which uses an operating handle to control the contactor, generally adopts a 36-volt safety voltage. However, in the working environment around a blast furnace, the presence of gases and dust can easily cause corrosion and oxide film formation on the electrical contacts of the hoisting device's circuit control components. This increases the contact resistance of the electrical contacts, leading to poor contact and thus increasing the likelihood of hoisting malfunctions. Therefore, a monorail crane hoisting device with good sealing performance is provided. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example 1, referring to Figure 1-4 A well-sealed monorail hoisting device includes a base 1, with supports 2 fixed on both sides of the top of the base 1. A drum 3 is rotatably mounted between the two supports 2 via bearings. A reducer 6 is fixed on one side of one of the supports 2. The output end of the reducer 6 is connected to one end of the drum 3. A servo motor 5 is connected to the input end of the reducer 6. The servo motor 5 is fixed to the outer wall of the reducer 6. An electrical control box 8 is provided on one side of the base 1. The electrical control box 8 is mounted on the base 1 by a fixing structure. Semiconductor cooling chips 10 are arranged at equal intervals on one side wall of the electrical control box 8. The cold end of the semiconductor cooling chip 10 is located inside the electrical control box 8, and the hot end of the semiconductor cooling chip 10 is located outside the electrical control box 8. A heat dissipation structure is provided on the side wall of the base 1 and on one side of the electrical control box 8.

[0021] A sealing door 9 is provided on one side of the electrical control box 8, and a sealing strip is provided on the side of the sealing door 9. A wire hole 16 is provided on the electrical control box 8, and a sealing sleeve is provided at the wire hole 16. After the conductive cable passes through the wire hole 16, the sealing sleeve blocks the gap at the wire hole 16, effectively reducing the air permeability of the electrical control box 8 and greatly preventing dust from entering the electrical control box 8 and causing component malfunctions.

[0022] A steel wire rope 4 is wound on the drum 3. One end of the steel wire rope 4 is fixed to the drum 3, and the other end of the steel wire rope 4 is equipped with a hook 7.

[0023] The servo motor 5 drives the reducer 6 to rotate, which in turn drives the drum 3 to rotate, thereby winding and unwinding the wire rope 4, making it easier to lift objects.

[0024] The heat dissipation structure includes a fixing frame 11 fixed to one side of the base 1, and two cooling fans 12 are symmetrically fixed on the fixing frame 11.

[0025] Temperature sensor 13 and controller are fixed on the inner wall of electrical control box 8. Cooling fan 12, semiconductor cooling chip 10 and temperature sensor 13 are all electrically connected to controller.

[0026] Temperature sensor 13 detects the temperature inside the electrical control box 8 and feeds the temperature information back to the controller. When the temperature is high, the controller controls the thermoelectric cooler 10 and the cooling fan 12 to turn on. The cold end of the thermoelectric cooler 10 cools the circuit components inside the electrical control box 8 to ensure the stable operation of the circuit components. The cooling fan 12 dissipates heat from the hot end of the thermoelectric cooler 10 to ensure the stable operation of the thermoelectric cooler 10.

[0027] Example 2 is an optimization based on Example 1, specifically:

[0028] The fixing structure includes a fixing rod 18 fixed to the outer wall of one side of the base 1, two supporting screws 14 fixed to one side of the fixing rod 18, and two connecting sleeves 17 fixed to the outer wall of one side of the electrical control box 8. The two connecting sleeves 17 are respectively sleeved on the two supporting screws 14, and a nut 15 is screwed to one end of each of the two supporting screws 14.

[0029] The electrical control box 8 is fixed by fitting the connecting sleeve 17 on the support screw 14 of the fixing rod 18 and tightening the nut 15 on the support screw 14. The disassembly is also quick and easy, making maintenance convenient.

[0030] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
