[0050] Working principle of the present invention:

[0051] When in use, when the motor 3 drives the crane to move through the electric trolley, the motor 3 will generate noise when it is running. The noise will be initially absorbed by the sound-absorbing cavity 63 and the noise-reducing sponge inside it. The weakened noise will enter the second cavity 81 and be absorbed again by the sound insulation pad 82 inside it. The weakened noise will continue to be transmitted outward. The third cavity 47 and the heat-conducting block 72 inside it will weaken the noise again to reduce the noise of the motor 3. At the same time, the roller 655 will rotate on the guide rail with the crane. The roller 655 will drive the first gear 653 and the rotating shaft 651 to rotate through the second gear 654, and the rotating shaft 651 will drive the blade 652 to rotate. The air flow near the air inlet 61 enters the heat dissipation tube 41 and is guided by the spiral air guide strip 62. When the flow rate reaches a certain level, a certain vortex will be formed between the motor 3 and the heat dissipation tube 41, further increasing the gas flow rate. The gas flow will take away the heat near the motor 3 and then be discharged from the air outlet 64. Part of the heat will be transferred to the connecting tube 42 through the heat dissipation tube 41 and the support plate 44. Part of the heat on the connecting tube 42 will be transferred to the outside of the shell 45 through multiple heat-conducting blocks 72 and heat-conducting columns 74, and will be dissipated through multiple fins 92 on the outer wall of the shell 45. The noise of the motor 3 can be reduced while dissipating the heat of the motor 3, thereby maintaining the stable performance of the crane.

[0052] To sum up: the new suspended single-beam lifting equipment, by providing a main body 1, a fixing plate 2, a motor 3 and a noise reduction device, can multiple absorb the noise generated by the operation of the motor 3 on the crane, and can multiple dissipate the heat of the motor 3, thereby solving the problem that the existing single-beam lifting equipment generates a large noise during operation, and if the noise of the motor 3 is reduced, the heat dissipation performance of the motor 3 will be reduced, and the problem that the heat dissipation and noise reduction of the motor 3 cannot be taken into account at the same time.
