[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] See Figures 1-4 The cross turnout for an aerial self-propelled trolley provided by the utility model includes a fixed frame 1 and a drive motor 2. A turntable 4 is provided on the fixed frame 1. The drive motor 2 is connected to the turntable 4 through a connecting rod assembly 3. The drive motor 2 can drive the turntable 4 to rotate 90 degrees in both directions through the connecting rod assembly 3; a movable rail 7 is provided on the turntable 4 for docking with a fixed rail 13, and a fixed-end docking mounting seat 6 is provided on the fixed frame 1. A groove is provided on the movable rail 7, and a convex slot is provided on the fixed rail 13. The fixed rail 13 and the movable rail 7 are connected by plugging and fixed by the fixed-end docking mounting seat 6.

[0020] The cross turnout for an aerial self-propelled trolley provided by the present invention has a movable end limit block 10 provided on the turntable 4, and a first fixed end limit block 11 and a second fixed end limit block 12 provided on the fixed frame 1; the first fixed end limit block 11 and the second fixed end limit block 12 are arranged at 90 degrees along the outer circumferential edge of the turntable 4.

[0021] The cross turnout for an aerial self-propelled trolley provided by the present invention has the following working process: the driving motor 2 is connected to the turntable 4 through the connecting rod assembly 3, and the movable rail 7 is installed on the turntable 4 using the track mounting seat 8. The driving motor 2 shaft rotates half a circle to drive the connecting rod assembly 3 and the turntable 4 to rotate 90 degrees. When the movable end limit block 10 on the turntable 4 contacts the first fixed end limit block 11 or the second fixed end limit block 12, the turntable 4 stops. The position of the fixed limit block is adjustable and can be used to adjust the stop position of the turntable 4. There are two stop sensing switches 9, which are located on the outside of the first fixed end limit block 11 or the second fixed end limit block 12; when the two stop sensing switches 9 sense signals in succession, the sensor signal after the track switching is completed is fed back to the trolley group, and the trolley can pass through the turnout after receiving the signal.

[0022] The cross-turnout for an aerial self-propelled trolley provided by this utility model features an aluminum rail mounting bracket 6 for mounting the fixed rail 13. The movable rail 7 is machined with a groove, and the fixed rail 13 is machined with a protruding slot, allowing for precise positioning of the movable and fixed rails 7 and preventing relative vertical displacement. The fixed rail mounting brackets 6 feature waist-shaped holes, facilitating adjustment of the gap between the fixed rail 13 and the movable rail 7 during installation. Four fixed rail mounting brackets 6 are mounted on the four sides of the fixed frame 1, allowing for easy adjustment of the straightness of the fixed rail 13 and movable rail 7 in three directions during installation.

[0023] In summary, the cross switch for the aerial self-propelled trolley provided by the utility model can not only realize track changing quickly and automatically, but also has a simple structure, is safe and reliable, and is easy to install and maintain.

[0024] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make slight modifications and improvements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the definition of the claims.
