[0024] Please see Figures 1-5 In this embodiment of the present invention, an explosion-proof remote control device includes an explosion-proof housing 1. The explosion-proof housing 1 includes an antistatic layer 101, a metal shell 102, and an anti-corrosion layer 103. Two sets of shock-absorbing columns 2 are installed on the inner wall of the explosion-proof housing 1. A connecting plate 3 is installed on the side of the two sets of shock-absorbing columns 2 that are close to each other. A fixing frame 4 is installed on the side of the two sets of connecting plates 3 that are close to each other. A symmetrical first bearing 5 is embedded in the inner wall of the fixing frame 4. This not only makes the device explosion-proof, but also makes it convenient for people to use the device to lift and transport items.

[0025] The inner rings of the two first bearings 5 ​​are each equipped with a connecting rod 6. The two connecting rods 6 are connected at their close ends and a rotating roller 7 is installed together. Two heat dissipation windows 14 are opened on the right side of the explosion-proof housing 1. Dustproof nets 15 are installed on the inner walls of the two heat dissipation windows 14. A steel cable 8 is wound around the outer surface of the rotating roller 7. A connecting block 16 is installed at one end of the steel cable 8. A fixing hook 17 is installed on the bottom surface of the connecting block 16. A second bearing 12 is embedded in the outer surface of the explosion-proof housing 1. A hook 13 is installed on the inner ring of the second bearing 12. This not only makes it convenient for people to use the equipment to lift and transport items, but also enables the equipment to effectively dissipate heat and prevent external dust from entering the interior of the equipment.

[0026] Two baffles 9 are installed on the outer surface of the rotating roller 7. Protective pads 10 are installed on the side of the two baffles 9 that are close to each other. A hydraulic motor 11 is installed on the left side of the fixed frame 4. The output end of the hydraulic motor 11 is connected to one of the connecting rods 6 through a coupling. The metal shell 102 is made of high-strength aluminum alloy with added specific trace elements such as titanium and chromium. The anti-corrosion layer 103 is an anti-corrosion paint surface, and the anti-static layer 101 is a nano coating. It can not only protect the steel cable 8, but also prevent the explosion-proof shell 1 from corrosion or cracking, thereby making the equipment safer.

[0027] The working principle of this utility model is as follows: First, people can use wires to connect the equipment to the ground wire. The nano-coating of the antistatic layer 101 conducts the static electricity generated on the surface of the shell and releases it through the grounding device to prevent static electricity from causing danger. The high-strength aluminum alloy metal shell 102 with titanium, chromium and other elements, combined with the anti-corrosion paint surface of the anti-corrosion layer 103, ensures the stability of the shell. During operation, the hydraulic motor 11 is powered on, and its output end drives the connecting rod 6 through the coupling, so that the rotating roller 7 rotates under the support of the first bearing 5 to wind or release the steel cable 8. The fixed hook 17 is used to hang items. The baffle 9 and the protective pad 10 prevent the steel cable 8 from slipping or being worn. The heat generated during operation is discharged through the two heat dissipation windows 14 on the right side of the explosion-proof shell 1. The dustproof net 15 blocks dust. The shock-absorbing column 2, the connecting plate 3 and the fixed frame 4 form a shock-absorbing structure to reduce the vibration of the device.
