[0029] Example 1

[0030] like Figure 1-4 As shown, a lifting and transfer cam lifting mechanism according to an embodiment of the present utility model includes multiple bases 1. A main drive mechanism 2 is provided in the middle of the top surface of the base 1. An electro-hydraulic push rod 3 is connected to the left side of the main drive mechanism 2. A moving plate 4 is provided on the top of the main drive mechanism 2. A guide mechanism 5 is provided on the top of the moving plate 4. A braking mechanism 6 is connected to one side of the guide mechanism 5. A vertical plate 7 is provided in the middle of one side of the base 1. An auxiliary drive mechanism 8 is provided in the middle of one side of the vertical plate 7, and the braking mechanism 6 is provided on one side of the auxiliary drive mechanism 8.

[0031] In this embodiment, the electro-hydraulic actuator 3 serves as a power source, directly driving the transmission components inside the main drive mechanism 2. The main drive mechanism 2 is rigidly connected to the moving plate 4 through a sliding component, transmitting linear motion to the moving plate 4. The guide mechanism 5 is fixed on the moving plate 4 and moves laterally synchronously with the moving plate 4. The guide mechanism 5 cooperates with the structure inside the braking mechanism 6 to convert the lateral movement into height adjustment. The braking mechanism 6 is located inside the guide mechanism 5, and its height is controlled by a specific trajectory of the guide mechanism 5. The components inside the auxiliary drive mechanism 8 slide to coordinately adjust the height of the braking mechanism 6.

[0032] Example 2

[0033] The main drive mechanism 2 includes a main drive groove 9 and a main drive block 10. The main drive groove 9 is carved in the middle of the top surface of the base 1. The main drive block 10 is slidably disposed in the main drive groove 9. A circular hole 11 is carved in the left side of the inner cavity of the main drive groove 9 and extends to the left side of the base 1. The electro-hydraulic push rod 3 extends into the main drive groove 9 through the circular hole 11 and is connected to the left side of the main drive block 10. The main drive groove 9, located in the middle of the top surface of the base 1, is a straight sliding groove that restricts the main drive block 10 to slide only horizontally to prevent offset or jamming. The main drive block 10 is rigidly connected to the electro-hydraulic push rod 3 and bears the main thrust. The moving plate 4 is fixedly connected to the main drive block 10 and acts as an intermediate carrier to transmit the main drive motion to the guide mechanism 5. The circular hole 11 provides an installation channel for the electro-hydraulic push rod 3. The hole diameter is slightly larger than the piston rod diameter to avoid motion interference. The electro-hydraulic push rod 3 pushes the main drive block 10, and the main drive block 10, along with its components, moves laterally in the main drive groove 9 by sliding.

[0034] The guiding mechanism 5 includes a guide plate 12 and a guide groove 13. The guide plate 12 is disposed on the top of the movable plate 4, and a guide groove 13 is cut out on one side of the guide plate 12. The guide plate 12 is fixed on the movable plate 4, and the guide groove 13 provided on the guide plate 12 has a curved structure. The shape of the guide groove 13 determines the movement trajectory of the brake wheel 18.

[0035] The auxiliary drive mechanism 8 includes an auxiliary drive groove 14 and an auxiliary drive block 15. The auxiliary drive groove 14 is carved out in the middle of one side of the vertical plate 7. The auxiliary drive block 15 is slidably disposed in the auxiliary drive groove 14. The auxiliary drive block 15 slides in the auxiliary drive groove 14 and is connected to a convex block 16. Adjusting the position of the convex block 16 further corrects the height of the brake wheel 18. When adjusting the height, the convex block 16 assists in the height adjustment by sliding the auxiliary drive block 15 on one side in the auxiliary drive groove 14.

[0036] The braking mechanism 6 includes a convex block 16, a brake shaft 17, and a brake wheel 18. The convex block 16 is disposed on one side of the auxiliary drive block 15, and the brake shaft 17 is disposed on one side of the convex block 16. The brake wheel 18 is sleeved on the outer wall of the brake shaft 17 and is disposed in the guide groove 13. A lifting plate 19 is disposed between the convex blocks 16. The main drive block 10, along with its components, slides laterally in the main drive groove 9, causing the movable plate 4 fixedly connected to the top of the main drive block 10 and its guide mechanism 5 to slide laterally, i.e., the guide plate 12 is driven to slide laterally. The brake wheel 18 located in the guide groove 13 and its components are adjusted in height as the guide mechanism 5 moves laterally.

[0037] In summary, with the help of the above-mentioned technical solution of this utility model, when this device is in use, the piston rod of the electro-hydraulic push rod 3 is directly connected to the main drive block 10 to provide horizontal thrust. The main drive block 10 slides in the main drive groove 9 and moves laterally through sliding. The moving plate 4 is rigidly fixed to the top of the main drive block 10 and moves laterally synchronously with the main drive block 10. The guide plate 12 is fixed on the moving plate 4 and drives the guide groove 13 and the brake wheel 18 inside it when moving laterally. When the guide plate 12 moves laterally, the oblique guide groove 13 forces the brake wheel 18 to move along the groove, which is converted into vertical displacement. When adjusting the height, the convex block 16 is adjusted by sliding the auxiliary drive block 15 on one side in the auxiliary drive groove 14.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
