[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] Figure 1 This is a schematic diagram of the lifting device switching mechanism of this utility model.

[0014] Please see Figure 1The lifting device switching mechanism provided by this utility model includes a base 1, on which a front switching component, a rear switching component, and a lifting device guide component are provided. The front switching component consists of a rotatable positioning pin 3 driven by a rotary drive motor 2, a lever 4, a limit block, a detection switch, etc. Specifically, the rotatable positioning pin 3 is provided on a positioning pin mounting seat 28. One side of the positioning pin mounting seat 28 is provided with a first position limit block 5 and a first detection switch 7, and the other side of the positioning pin mounting seat 28 is provided with a second position limit block 6 and a second detection switch 8. The base 1 is fixed on a mounting beam 26, and the mounting beam 26 is provided with adjustable feet 27.

[0015] In a preferred embodiment, the rear switching assembly of this utility model comprises a left support block adjustment drive motor 9, a right support block adjustment drive motor 10, a switching positioning pin 11, a slide rail 12, a slider limit block 13, a lifting device descent detection switch 14, and a switching assembly induction switch 15. Above the left support block adjustment drive motor 9 is a left connecting rod 22 and a left connecting rod extension induction switch 23; above the right support block adjustment drive motor 10 is a right connecting rod 24 and a right connecting rod retraction induction switch 25. The lifting device guide assembly comprises X and Y direction guide blocks and a Z direction limit rod; specifically, the lifting device guide assembly includes a symmetrically arranged first guide assembly and a second guide assembly. The first guide assembly includes a left X direction guide block 16, a left Y direction guide block 17, and a left Z direction limit rod 18; the second guide assembly includes a right X direction guide block 19, a right Y direction guide block 20, and a right Z direction limit rod 21.

[0016] With the front and rear switching components of the lifting device in their initial positions, the lifting device moves to the switching station and slowly descends, its positioning hole falling into the switching positioning pin 11. The switching component's inductive switch 15 detects the lifting device, and the rotary drive motor 2 on the front switching component rotates, rotating the positioning pin 3 and causing the lever 4 to rotate, thus switching the front positioning position of the lifting device. Simultaneously, the left support block adjustment drive motor 9 and the right support block adjustment drive motor 10 on the rear switching component rotate, causing the cam arm to rotate and moving the rear switching positioning pin 11 along the slide rail 12, thus switching the rear positioning position. After switching to the correct position, the lifting device descent detection switch 14 sends a signal back to the lifting device, causing it to rise and disengage from the switching positioning pin 11. Once the lifting device detection switch loses its signal, the lifting device moves away from the switching position and enters the conveyor line.

[0017] 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 can make some 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 determined by the claims.
