DETAILED DESCRIPTION

[0026] like Figure 1-4 As shown, the utility model provides an AR projection device for installing a bridge box girder, including a drone 100, wherein propellers 101 are arranged at the four corners of the drone 100, and a battery compartment 102 is arranged at the bottom of the drone 100;

[0027] AR projector 200, which is embedded in the front side of the drone 100;

[0028] A vibration reduction assembly 300, which is disposed between the AR projector 200 and the drone 100. The vibration reduction assembly 300 includes a fixing plate 301, a spring A 304, a piston rod 305, a fixing column 306, and a damping plate 307. The spring A 304 and the piston rod 305 are both disposed at the bottom of the fixing plate 301, the fixing column 306 is sleeved on the outside of the piston rod 305, and the damping plate 307 is disposed at the bottom end of the spring A 304;

[0029] The stabilizing component 400 is arranged at the bottom of the drone 100 . The stabilizing component 400 includes a hook 401 , a connecting buckle 403 and a chain 404 . The connecting buckle 403 is arranged at the upper end of the hook 401 , and the bottom end of the chain 404 is connected to the connecting buckle 403 .

[0030] Furthermore, in the present embodiment, movable grooves 201 adapted to the vibration reduction assembly 300 are provided on the four sides of the AR projector 200, and the bottom of the fixed cylinder is threadedly engaged with the AR projector 200 through the movable groove 201. The movable groove 201 provides the vibration reduction assembly 300 with a telescopic space, thereby facilitating the vibration reduction assembly 300 to perform a vibration reduction function.

[0031] In this embodiment, the damping plate 307 is sleeved on the outside of the fixed tube and is threadedly matched with the fixed tube. The damping plate 307 is fixedly connected to the bottom end of the spring A 304. The upper ends of the spring A 304 and the piston rod 305 are fixedly connected to the fixed plate 301. Through the connection between the damping plate 307 and the fixed tube, the position of the damping plate 307 on the fixed tube can be adjusted according to the vibration size of the drone 100, and the stretching length of the spring can be adjusted to achieve the adjustment of the vibration reduction size.

[0032] In addition, the stretched length of the spring determines its stiffness. The longer the stretched length, the softer the spring and the lower the stiffness. Conversely, the shorter the stretched length, the harder the spring and the higher the stiffness, which allows the spring to better adapt to different vibration environments and maximize the vibration reduction effect.

[0033] In this embodiment, at least three springs B 303 are provided on the upper surface of the fixing plate 301, and damping blocks 302 are fixed to both ends of the spring B 303. The damping blocks 302 are respectively connected to the fixing plate 301 and the drone 100 by screws, and are connected to the drone 100 through the springs B 303 to perform preliminary vibration reduction. The double vibration reduction structure improves the vibration reduction effect, and the spring B303 is stabilized by the damping block 302 to prevent the spring from being in a state of continuous jumping.

[0034] In this embodiment, the upper end of the chain 404 is screwed to the drone 100, and a bolt 405 is provided between the lower end of the chain 404 and the connecting buckle 403. The bolt 405 passes through the upper end of the connecting buckle 403 and the chain 404, and the chain 404 is buckled on the connecting buckle 403 through the bolt 405.

[0035] In addition, considering the firmness, a through hole can be opened at the bottom end of the chain 404 for the bolt 405 to pass through, so as to fix the bottom end of the chain 404. Whether the bottom end of the chain 404 is fixed or movable is selected according to the actual situation.

[0036] In this embodiment, a connecting head 402 is provided at the upper end of the hook 401, and a connecting buckle 403 passes through the connecting head 402. The connecting buckle 403 is screwed to the connecting head 402, and the connection between the connecting buckle 403 and the connecting head 402 is fixed by screws to realize the connection between the hook 401 and the connecting buckle 403.

[0037] In this embodiment, the hook 401, the connecting buckle 403 and the chain 404 are all made of aluminum alloy or glass fiber reinforced plastic. Based on the material of the hook 401, the connecting buckle 403 and the chain 404, the weight is light while ensuring the strength, thereby reducing the impact on the weight of the drone 100.

[0038] In addition, considering the balance of the drone 100 , the stabilizing component 400 is disposed on the left and right sides of the bottom of the drone 100 , the four corners of the bottom of the drone 100 (ie, below the propeller 101 ) or at the bottom center of the drone 100 .

[0039] Specifically, when the box girder of the bridge erection machine needs to be installed, the design scheme of the installation is stored in the AR projector 200. The propeller 101 can be controlled to rotate by wireless data transmission, inserting a memory card, etc. Then, the remote controller of the drone 100 is used to control the rotation of the propeller 101. The drone 100 starts to fly to the pre-designed position, and the box girder is projected to the installation position in the design scheme through the AR projection device. The workers perform the construction and installation of the box girder according to the projection image position, and the power of the drone 100 comes from the battery in the bottom battery compartment 102;

[0040] Considering that the drone 100 will vibrate when maintaining the flight state, the vibration will affect the projection effect of the AR projector 200, and the projected image will shake. Therefore, a vibration reduction assembly 300 is set between the AR projection device and the drone 100 for vibration reduction. The damping block 302 on the spring B 303 at the upper end of the fixing plate 301 is connected to the drone 100 for preliminary vibration reduction. The spring A 304 and the piston rod 305 and the fixing cylinder perform piston movement to further reduce the impact of the vibration on the AR projector 200. The vibration reduction effect is adjusted by adjusting the position of the damping plate 307 on the fixing cylinder. The double vibration reduction structure improves the vibration reduction effect.

[0041] Taking into account that the wind may blow the drone 100, causing the drone 100 to be blown and the projected image of the AR projector 200 to shift, a stabilizing component 400 is provided at the bottom of the drone 100, and the hooking angle of the hook 401 is set according to the wind direction during use, and the opening direction of the hook 401 is consistent with the wind direction, and the hook 401 is hung on the building at the construction site of the bridge erection machine box beam, and the drone 100 is pulled by the chain 404 connected to the hook 401. After the drone 100 is blown, the drone 100 can be hooked to avoid excessive displacement of the position of the drone 100 being blown, reduce the adjustment time, and be able to adjust the position of the drone 100 more quickly and perform projection, and the stabilizing component 400 is selected to be light in weight and has a certain strength material to reduce the impact on the drone 100.

[0042] In addition, in consideration of the safety of workers in bad weather, construction will not be carried out, so there will be no extreme usage.

[0043] The components of the drone 100, propeller 101, battery compartment 102, AR projector 200, fixing plate 301, damping block 302, spring B 303, spring A 304, piston rod 305, fixing column 306, damping plate 307, hook 401, connector 402, connector buckle 403, chain 404, bolt 405 of the utility model are all universal standard parts or components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods.
