[0032] Reference below Figure 1-Figure 2 A civil air defense door transportation device is described in detail with a specific embodiment. It is worth noting that the following description is only an exemplary description and not a specific limitation of the utility model.

[0033] like Figure 1-Figure 2 As shown, a civil air defense door transportation device includes an upper transportation mechanism and a lower transportation mechanism.

[0034] Among them, the upper transport mechanism includes an upper guide rail 100 arranged above the workshop, an upper pulley 110 arranged on the upper guide rail 100, a first driving component that drives the upper pulley 110 to move along the upper guide rail 100, and a lifting component arranged on the upper pulley 110. The lifting component includes a drum 120, a servo motor 130 that drives the drum 120 to move, a wire rope 140 wound on the drum 120, and a hook 150 arranged at the end of the wire rope 140 for suspending a protective door; the lower transport mechanism includes a lower guide rail 160 arranged on the ground and parallel to the upper guide rail 100, a lower carriage 170 arranged on the lower guide rail 160, and a second driving component that drives the lower carriage 170 to move along the lower guide rail 160. The second driving component is linked to the first driving component. The lower carriage 170 is provided with a receiving groove 180 for placing the protective door, and the receiving groove 180 is provided with a fixing component used to fix the protective door. During hoisting, the upper transport mechanism is used first. The upper pulley 110 of the upper transport is brought to the top of the civil air defense door along the upper guide rail 100 through the first drive assembly. The servo motor 130 of the lifting assembly rotates to release the wire rope 140, so that the hook 150 can be connected to the civil air defense door. Then the servo motor 130 retracts the wire rope 140 to lift the civil air defense door. The upper pulley 110 lifts the civil air defense door to the top of the lower transport mechanism, and puts the lower edge of the civil air defense door into the receiving groove 180. Then the second drive assembly is linked with the first drive assembly, and the lower pulley 170 transports the civil air defense door under the action of the second drive assembly. At the same time, the upper pulley 110 moves synchronously. This is because the upper lifting assembly plays the role of tightening the protective door to prevent the civil air defense door from swinging. Therefore, the pressure on the crane can be reduced, and the civil air defense door will not swing during the hoisting process, thereby improving safety.

[0035] According to some embodiments of the present invention, the first drive assembly and the second drive assembly are both electrically driven, and the upper pulley 110 and the lower pulley 170 are easily controlled by the motor drive.

[0036] According to some embodiments of the present invention, the upper pulley 110 and the lower pulley 170 are both provided with sensors 190 for detecting each other. The sensor 190 can ensure that the upper pulley 110 and the lower pulley 170 can move in a linked manner, so that the civil air defense door can be transported smoothly.

[0037] According to some embodiments of the present invention, the upper pulley 110 and the upper guide rail 100, and the lower pulley 170 and the lower guide rail 160 are all slidably connected by steel wheels 200. The use of steel wheels 200 ensures that they will not be crushed during transportation and is conducive to cooperation with the guide rail.

[0038] According to some embodiments of the present invention, two lifting assemblies are provided on the upper pulley 110 along the direction of the upper guide rail 100. Providing two lifting assemblies is conducive to lifting the civil air defense door, and it is also more stable during transportation.

[0039] According to some embodiments of the present invention, the lifting assembly is further provided with a reducer connected to the servo motor 130. The reducer is provided to enable the lifting assembly to always run at a low speed to ensure safety.

[0040] According to some embodiments of the present invention, the fixing assembly includes a pressing block 210 disposed on the side of the accommodating groove 180 and a pressing cylinder 220 driving the pressing block 210 to press the protective door. The pressing cylinder 220 is arranged to drive the pressing to press the protective door, which can reduce the occurrence of swinging of the civil air defense door.

[0041] According to some embodiments of the present invention, the fixing assembly includes an electromagnet 230 disposed at the bottom of the receiving groove 180. The electromagnet 230 is disposed to magnetically fix the civil air defense door, further reducing the occurrence of swinging of the civil air defense door.

[0042] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
