[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4This utility model provides a technical solution: a robot high-altitude positioning mechanism, including a conical base 1, a plurality of bearing seats 11 are uniformly fixed to the outer side of the conical base 1 by welding, a connecting arm 51 is rotatably arranged on one side of the bearing seat 11, a crank rod 5 is rotatably installed on the top of the connecting arm 51, a connecting rod 54 is rotatably connected to the top of the crank rod 5, a positioning platform 6 is movably arranged between the plurality of connecting rods 54, the bottom of the positioning platform 6 is movably connected to the top of the connecting rod 54 by bearings, the three crank rods 5 are used to control the overall lifting, angle adjustment and rotation of the positioning platform 6, the movement of one end of the crank rod 5 is controlled by adjusting the orientation angle of the connecting arm 51, thereby controlling the movement of the positioning platform 6, and the connecting rod 54 is used to swing the crank rod 5 while it rotates relative to the positioning platform 6;
[0020] A gyroscope 61 is installed at the bottom of the positioning platform 6. The gyroscope 61 is electrically connected to the external control system. Multiple laser sensors 4 are evenly installed on the outer wall of the positioning platform 6. The laser sensors 4 are electrically connected to the external control system. The gyroscope 61 detects whether the positioning platform 6 is in a horizontal state, thereby determining whether the orientation angle can be adjusted. The laser sensors 4 detect the surrounding environment to know the position of the robot above in space.
[0021] The inner wall of the conical base 1 is fixed with a mounting plate 13 by welding. Adjustment motors 7 are evenly fixed on the mounting plate 13. The adjustment motors 7 are connected to an output shaft 71 through a coupling. A bevel gear 72 is sleeved on the outside of the output shaft 71. By driving the adjustment motors 7 to work, the output shaft 71 rotates and causes the bevel gear 72 to rotate.
[0022] A rotating shaft 53 is rotatably mounted on the inner wall of the bearing housing 11 via a bearing. A bevel gear disk 52 is fixedly mounted on one end of the rotating shaft 53. The bevel gear disk 52 meshes with a bevel gear 72. The outer wall of the rotating shaft 53 is connected to the connecting arm 51. When the bevel gear 72 rotates, the bevel gear disk 52 rotates through the meshing action, thereby controlling the angle of the connecting arm 51.
[0023] The connecting arm 51 includes an arc-shaped block 511, an electric push rod 513 is mounted on the top of the arc-shaped block 511, the output end of the electric push rod 513 is connected to the arc-shaped block 511, and a folding bladder 512 is connected between the arc-shaped block 511 and the electric push rod 513. By activating the electric push rod 513, the distance between the bottom and top ends of the arc-shaped block 511 can be adjusted. The body of the electric push rod 513 is movably connected to the bottom end of the curved rod 5. The folding bladder 512 is used to freely extend and retract when adjusting the distance to maintain the sealing of the device.
[0024] Several movable rollers 2 are installed at the bottom of the conical base 1, and a radar sensor 3 is installed at the top of the conical base 1. The movable rollers 2 drive the entire conical base 1 to move, and the radar sensor 3 achieves spatial positioning.
[0025] By employing an adjustment structure with three cranks and bevel gear transmission, this positioning method, compared to a positioning platform with three telescopic cylinders, utilizes gear meshing transmission and avoids angular deviations caused by repeated extension and retraction of the telescopic cylinders, resulting in higher positioning accuracy. During operation, if the height of the positioning platform 6 needs adjustment, the three electric push rods 513 are simultaneously activated, raising or lowering the bottom of the crank 5 to adjust the height of the positioning platform 6. When the positioning platform 6 needs to rotate, the three adjustment motors 7 are activated simultaneously, causing the connecting arms 51 to swing, thereby adjusting the circumferential angle of the positioning platform 6. When the orientation angle of the positioning platform 6 needs adjustment, for example, when the gyroscope 61 detects a point requiring raising or lowering, the corresponding electric push rod 513 is activated, causing one of the connecting arms 51 to extend or retract, thus changing the orientation angle of the positioning platform 6.
