For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0022] As Figures 1 to 2 As shown, the unmanned aerial vehicle body 1 is uniformly provided with a plurality of groups of wings 2, so that the unmanned aerial vehicle body 1 can move freely in the air.
[0023] The mounting bracket 3, the rudder 4 and the positioning device are arranged on the unmanned aerial vehicle body 1, the mounting bracket 3 is fixedly arranged in an inclined manner, two mounting brackets 3 are arranged, and the two mounting brackets 3 are rotatably provided with the rudder 4, one end of one group of rudders 4 is connected with the manipulator 5 in a matched manner, one end of the other group of rudders 4 is connected with the first motor 6 in a matched manner, the output end of the first motor 6 is connected with the paving plate 7, the rudders 4 are connected in parallel, and the adjacent rudders 4 are connected through the connecting block 16.
[0024] In this embodiment, the positioning device includes a detection camera 8, a push rod 9, a laser pen 10, a battery 11 and a controller 12, the unmanned aerial vehicle body 1 is provided with a detachable detection camera 8 at the upper end, a push rod 9 at the lower end, and a detachable laser pen 10 at the lower end of the push rod 9;The controller 12 and the battery 11 are arranged staggered on the inner side of the unmanned aerial vehicle body 1, and the battery 11 is used to power the manipulator 5, the first motor 6 and the push rod 9.
[0025] The two sides of the paving slab 7 are perpendicular, and a first slope 13 and a second slope 14 are provided between the two sides of the paving slab 7. The inclination angle of the first slope 13 is greater than that of the second slope 14. A groove 15 is provided on the second slope 14 for shoveling up excess cement during the paving process.
[0026] The robotic arm 5 is equipped with a second motor 17, the output of which is used to control the rotation and extension of the robotic arm 5.
[0027] The controller 12 is electrically connected to the robotic arm 5, the first motor 6, the second motor 17, the detection camera 8, the push rod 9, and the laser pointer 10.
[0028] It should be explained that the drone body 1, robotic arm 5, first motor 6, detection camera 8, push rod 9, laser pointer 10, battery 11, controller 12 and second motor 17 used in this utility model are all common models that can be purchased on the market. Their control connection methods are also easily implemented by those skilled in the art in the prior art. They are not the innovation of this utility model. Therefore, the specific electrical control connection methods are not shown in the figure and are not described in detail.
[0029] The working principle of this utility model is as follows: the drone body 1 arrives at the location where stairs need to be laid, that is, the wooden plank 18 that has been built. The detection camera 8 collects the data of the location. If an obvious stone protrusion is found, the wing 2 is used for coarse positioning. Multiple sets of servo motors 4 work together to make the robotic arm 5 reach the stone location. The second motor 17 rotates to drive the robotic arm 5 to extend and retract, grab the stone, and throw it to the location where stairs do not need to be laid.
[0030] Once there are no protruding stones inside the wooden plank 18, the drone body 1 returns to the side of the wooden plank 18, as... Figure 3 As shown, the first motor 6 adjusts the plank 7 to a vertical position, so that the plank 7 can be placed against the edge of the wooden board 18 to start working on the cement 19.
[0031] When the space within the wooden board 18 is sufficient to accommodate the paving board 7, such as Figure 4 As shown, the plank 7 is laid flat for leveling. If too much cement 19 is poured into the plank 18, the groove 15 will leave some cement 19 on the plank 7. Then the drone body 1 will transport this cement to the next plank 18. If the detection camera 8 finds that the cement 19 is dented, the drone body 1 will continue to push and compact the layer.
[0032] The work of the pushing flat treatment needs multiple cycles, after multiple cycles of the work of the pushing flat treatment, the detection camera 8 does not find obvious concave-convex areas, the push rod 9 moves to the position of the top of the next layer of the wood board 18, the wing 2 starts to drive the unmanned aerial vehicle body 1 to move from left to right, and the laser pen 10 starts to work and emits from the top of the next layer of the wood board 18, if a light spot is found at the lower end of the last layer of the wood board 18, it indicates that the two adjacent wood boards 18 are flush; if a part of the wood board 18 loses the light source of the laser pen 10, it indicates that the cement 19 of the part is still higher than the wood board, and the work of the pushing flat treatment should be continued to remove the excess cement 19.
[0033] The utility model uses the unmanned aerial vehicle body 1 to carry out the back and forth paving adjustment of the cement 19 needing to pave the stairs, and timely remedies the pit and the loss, and the laser pen 10 verifies the flatness of the paved cement 19, guarantees the flatness of the paving of the stairs.
[0034] The above embodiment is only the preferred embodiment of the utility model, and cannot be used to limit the right scope of the utility model, therefore, the modification, equivalent change, improvement and the like made according to the patent range of the utility model still belong to the range covered by the utility model.
