[0002] In modern industrial and logistics scenarios, the lifting and rotating adjustment mechanism of electric flatbed carts plays a key role. It integrates hydraulic, electric drive and precision sensing technologies to achieve precise lifting and flexible rotation, adapt to the operation requirements of different heights and angles, and is widely used in assembly, warehousing and transportation.

[0003] The existing lifting and rotating adjustment mechanism of electric flatbed carts plays a crucial role. On the one hand, it facilitates raising goods to the same height as the loading and unloading platform, effectively reducing the intensity of loading and unloading for workers. On the other hand, the rotation adjustment mechanism allows for precise adjustment of the goods' angle, facilitating loading and unloading at specific angles. However, the maximum height raised by the lifting and adjusting mechanism is fixed, making it difficult to customize for different usage scenarios. This necessitates purchasing different models and even different brands of electric flatbed carts, resulting in a large number of parts required for subsequent maintenance. To address the shortcomings of existing technology, this utility model provides a lifting and rotating adjustment mechanism for electric flatbed carts to solve the above problems.

This facilitates the use of different parts and makes maintenance easier.

[0026] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0027] This utility model embodiment discloses the lifting and rotating adjustment mechanism of the electric flatbed cart.

[0028] According to the appendix Figure 1 and 2 As shown, it includes:

[0029] A support base 8 is provided, and a lifting mechanism power unit 1 is installed on top of it;

[0030] A rotating platform 6 is disposed above a support base 8, and a rotating mechanism drive unit 5 is disposed at the bottom of the rotating platform 6;

[0031] Two sets of first fork arms 12 are disposed between the support base 8 and the rotating platform 6. A first connector 14 is provided in the middle of the first fork arm 12, a connecting fork arm 10 is provided at one end of the first fork arm 12, and a second connector 15 is provided between the first fork arm 12 and the connecting fork arm 10.

[0032] Two sets of second fork arms 13 are hinged to the first connector 14, and the second fork arms 13 and the connecting fork arms 10 are hinged to each other through the second connector 15.

[0033] A limiting unit 7 is provided on the support base 8. The limiting unit 7 is used to limit the connecting fork arm 10. The limiting unit 7 includes:

[0034] The fixed base 71 is fixedly connected to the support base 8;

[0035] The connecting plate 72 is fixedly connected to the fixed base 71 at its bottom end;

[0036] The limiting plate 73 is fixedly connected to the upper end of the connecting plate 72, and the limiting plate 73 abuts against the connecting fork arm 10.

[0037] A lead screw 17 is provided on the support base 8. A transmission chain 16 is connected between the bottom end of the lead screw 17 and the output end of the power unit 1 of the lifting mechanism. A lifting structure 18 is provided on the upper end of the lead screw 17. The lifting structure 18 is connected to the first fork arm 12 and the second fork arm 13 at the bottom.

[0038] The bottom of the rotating platform 6 is provided with a rotary support fixing plate 4, the bottom of the rotary support fixing plate 4 is provided with a rotary support frame 3, the bottom of the rotary support frame 3 is provided with a rotary mechanism drive unit 5, the bottom of the rotating platform 6 is fixedly connected to the output end of the rotary mechanism drive unit 5, and the bottom of the rotary support frame 3 is fixedly connected to an upper support platform 2.

[0041] The lifting mechanism power unit 1 drives the lead screw 17 to rotate via the transmission chain 16. The lifting structure 18 carries the guide rail assembly 11 to move vertically upward or downward. The fixed seat assembly 19 retracts horizontally along the guide rail assembly 11. The connecting fork arm 10 drives the slider at its bottom to retract horizontally along the guide rail body 9. The change in the angle parameters of the connecting fork arm assembly 10 causes the fork arm assembly structure and its top fixed rotating mechanism to move upward or downward along the vertical dimension, achieving the purpose of adjusting the height of the loaded workpiece. The height of the workpiece lifting depends on the vertical movement range of the lifting mechanism and the number of connecting fork arms 10. When the workpiece height meets the required height, the lifting mechanism power unit 1 continuously outputs power to maintain the stability of the workpiece height. The rotating mechanism drive unit 5 further adjusts the position and posture of the rotating platform 6 through the rotary support frame 3, dynamically and controllably adjusting the position and posture of the workpiece placed on the rotating mechanism in real time. By using different movement modes of the first and second mechanisms, the required height and position and posture within a predetermined height are achieved, realizing the purpose of height lifting and in-plane rotation position and posture adjustment.

[0042] The structure of the first fork arm 12, the second fork arm 13 and the connecting fork arm 10 working together allows the workpiece to be lifted to a height that depends on the vertical movement range of the lifting mechanism and the number of connecting fork arms 10. The connecting fork arms 10 can be quickly connected through the first connecting piece 14 and the second connecting piece 15, so as to customize the electric flatbed cart to different heights required in different scenarios to meet the usage requirements. At the same time, the parts required for maintenance are of a single type, which is convenient for maintenance.
