[0028] Example 1

[0029] See attached Figure 1-4 The present application provides a device for transporting accessories for civil air defense projects, including a base 1, on which a hanging mechanism, a limiting mechanism and a driving mechanism are provided. The hanging mechanism is used for hoisting civil air defense accessories, and the limiting mechanism is used for protecting civil air defense accessories during hoisting;

[0030] The hanging mechanism includes a hook 3, an arm 8 and a hydraulic component. The arm 8 drives the hook 3 to lift the civil air defense accessories through the hydraulic component. When the civil air defense accessories are lifted off the ground, they can be easily moved and transported. The hydraulic component includes a liquid bag 25 and a hydraulic rod. The hydraulic rod is arranged between the base 1 and the arm 8. The limiting mechanism includes an air bag 24 and an airbag 2. The airbag 2 wraps the civil air defense accessories by expanding itself, thereby providing a protective effect for the transportation of the civil air defense accessories. The liquid bag 25 and the hydraulic rod, as well as the airbag 2 and the airbag 24 are connected by pipelines, that is, when the liquid bag 25 is squeezed, the hydraulic oil will be transported to the hydraulic rod to extend its length, and when the airbag 2 is squeezed, gas will be filled into the airbag 2 to expand it. The driving mechanism includes a power component and a connecting plate 21. The power component squeezes the liquid bag 25 and the airbag 24 by driving the connecting plate 21 to move, so that the civil air defense accessories can be lifted off the ground and wrapped by the airbag 2 at the same time, thereby ensuring the convenience of the transportation process.

[0031] Preferably, the base 1 is U-shaped. By moving the device, the human air defense accessories can be located on the inner side of the base 1. This will ensure that the lifting process of the human air defense accessories will not cause a large shift in the center of gravity of the entire device, thereby maintaining the stability of the device. In addition, when the human air defense accessories are located on the inner side of the base 1 for lifting, there is no need to load and unload the human air defense accessories on the base 1, so that the transportation process can be more convenient. The airbag 2 is fixedly connected to the inner side of the base 1, and rollers 4 are installed at the four corners of the outer side of the bottom end of the base 1. The rollers 4 are universal wheels with built-in brakes. A handle 5 is fixedly connected to one side of the base 1, and a circular through hole is opened in the middle of one side of the base 1. The side wall of the base 1 is fixedly connected to the outer side of the circular through hole. The housing 6, the power assembly includes a motor 18, and the motor 18 is a servo motor. By controlling its rotation speed, the lifting speed of the human air defense accessories can be adjusted to facilitate its lifting and lowering. The motor 18 is fixedly connected to the inside of the housing 6.

[0032] When using the device to transport civil air defense project accessories, the device can be pushed to the outside of the accessories, that is, the accessories are placed on the inside of the U-shaped base 1, and then the lifting rope 9 is pulled and the accessories are hooked with the hook 3;

[0033] Then, the motor 18 can be started, and the motor 18 drives the two driving wheels 17 to rotate through the rotating shaft 16. The two driving wheels 17 can drive the two driven wheels 20 to rotate synchronously through two belts 19, so that the two threaded rods 14 rotate synchronously. The rotation of the threaded rod 14 can make the threaded sleeve 15 move in the horizontal direction. The threaded sleeve 15 can squeeze the air bag 24 and the liquid bag 25 by driving the connecting plate 21 to move.

[0034] Preferably, the base 1 is rotatably connected to a rotating shaft 16 at the circular through hole, and two driving wheels 17 are connected to the outside of the rotating shaft 16 by a key. Threaded rods 14 are rotatably connected at both ends between the inner walls on both sides of the base 1, and one end of the outside of the two threaded rods 14 is connected to a driven wheel 20 by a key.

Therefore, the transmission ratios of the two sets of driving wheels 17 and driven wheels 20 are the same during transmission, so the two threaded rods 14 can run synchronously, thereby ensuring that the two booms 8 can swing synchronously and jointly drive the civil defense accessories to rise.

[0035] Preferably, the outsides of the two threaded rods 14 are both threadedly connected with threaded sleeves 15, and there are four connecting plates 21, which are respectively fixedly connected at the top and bottom ends of the two threaded sleeves 15, one end of the air bag 24 and the liquid bag 25 are respectively fixedly connected to the two connecting plates 21 on the same threaded sleeve 15, and the other ends of the air bag 24 and the liquid bag 25 are fixedly connected to the inner wall of the base 1 away from the driven wheel 20.

[0036] At this time, the air bag 24 will fill the gas inside it into the air bag 2, so the air bag 2 can expand on the inner side of the base 1 and wrap around the outside of the accessory; at the same time, the liquid bag 25 can be squeezed to fill the hydraulic oil inside it into the sleeve 13, so the hydraulic oil can push the piston 26 to rise, and the piston 26 pushes the boom 8 to deflect upward through the support rod 12, and the deflection of the boom 8 pulls the lifting rope 9 through the connecting rod 10, thereby lifting the accessory off the ground.

[0037] Preferably, the top inner wall and the bottom inner wall of the base 1 are fixedly connected with guide rails 22 above and below the threaded sleeve 15, and the two connecting plates 21 on the same threaded sleeve 15 are respectively provided with slide grooves at the top and bottom ends, and the two connecting plates 21 are slidably connected with the two guide rails 22 at the two slide grooves, respectively, and the guide rails 22 can guide the movement of the connecting plates 21, that is, the guide rails 22 can limit the rotation of the connecting plates 21 so that it can only move in the horizontal direction. A steel wire hose 23 is fixedly connected between the two threaded sleeves 15 and the inner wall of the side of the base 1 away from the driven wheel 20 at the outside of the air bag 24 and the liquid bag 25. The steel wire hose 23 can limit the expansion of the air bag 24 and the liquid bag 25 to the surroundings, so that the two will only be compressed in a direction, thereby ensuring that the hydraulic oil and air can be smoothly filled into the sleeve 13 and the airbag 2.

[0038] Preferably, there are two booms 8 and two hydraulic rods, both ends of one side of the top of the base 1 are fixedly connected to fixed piles 7, the two booms 8 are rotatably connected to the tops of the two fixed piles 7 respectively, the hydraulic rod includes a strut 12 and a sleeve 13, the sleeve 13 is sleeved on the outside of the strut 12, one end of the strut 12 in the sleeve 13 is fixedly connected to a piston 26, the strut 12 is fixedly connected to the end of the boom 8, and the sleeve 13 is fixedly connected to the top of the base 1 away from the fixed pile 7.

[0039] Preferably, a connecting rod 10 is fixedly connected at the middle part between the two booms 8, a bearing 11 is fixedly connected at the middle part of the outer side of the connecting rod 10, a lifting rope 9 is fixedly connected to the bottom end of the bearing 11, and the hook 3 is fixedly connected to the bottom end of the lifting rope 9.

[0040] In this state, the accessories can be moved by pushing the device to achieve the effect of transportation, and the accessories can also be protected and limited under the wrapping of the airbag 2 to ensure the safety of the accessories during transportation; after the accessories are lifted to the destination, the motor 18 can be controlled to run in reverse to put the accessories back on the ground, and then the hook 3 can be unhooked and the device can be moved away.
