[0021] The following description is only used to disclose the present utility model so that those skilled in the art can implement the present utility model. The embodiments described below are only examples, and those skilled in the art can think of other obvious deformations. The basic principles defined in the following description can be applied to other implementation schemes, deformation schemes, improvement schemes, equivalent schemes, and other schemes that do not deviate from the spirit and scope of the present utility model.

[0022] [Example 1]

[0023] A lifting and guiding mechanism for logistics conveying equipment, such as Figure 1 , including a frame 40, a lifting drive assembly and a guide assembly.

[0024] The lifting drive assembly includes a power module, a lifting drive shaft 12 and an eccentric rotating body 14. The power module includes a power motor 13 and a transmission mechanism 11. The lifting drive shaft 12 is provided with two groups. The power motor 13 is connected to the two lifting drive shafts 12 through the transmission mechanism 11. The transmission mechanism 11 can be a sprocket chain transmission, a gear transmission, etc. The eccentric rotating body 14 is installed on the lifting drive shaft 12. The eccentric rotating body 14 is a cam or a crank arm. In this embodiment, a crank arm is used, such as Figure 5 A crank arm roller 15 is installed on the crank arm to reduce friction.

[0025] like Figure 3 , Figure 4 The guide assembly includes a guide body 20, which is a groove structure in which a reinforcing plate 26 is arranged. At least four guide bodies 20 are arranged, and the two inner guide bodies 20 form an inner guide 21, and the two outer guide bodies 20 form an outer guide 22.

[0026] Four eccentric rotating bodies 14 are arranged on each lifting drive shaft 12. The four eccentric rotating bodies 14 are used to drive four guide bodies 20 respectively. The two inner eccentric rotating bodies 14 are used to drive the inner guide 21, and the two outer eccentric rotating bodies 14 are used to drive the outer guide 22. The eccentric rotating bodies 14 driving the inner and outer guides are installed at different angles on the lifting drive shaft 12, such as Figure 5 In this embodiment, the eccentric rotating body 14 for driving the outer guide 22 and the eccentric rotating body 14 for driving the inner guide 21 are installed on the lifting drive shaft 12 at an angle of 180 degrees, so that when the inner guide is raised, the outer guide is lowered, and vice versa.

[0027] The power motor 13 drives the two sets of lifting drive shafts 12 to move, so that the crank arm swings at different angles. At the same time, the crank arm drives the guide body 20 to move up and down. The heights of different guides are switched by the rotation angle of the crank arm to realize the lifting function of the guide. By providing multiple sets of guides, different pallet specifications are compatible, and the internal and external guides are switched synchronously, which makes the control simple.

[0028] Optionally, in other embodiments, only two eccentric rotating bodies 14 may be provided on each lifting drive shaft 12 to connect the two guide bodies 20 of the inner and outer guides. For example, when one guide body 20 in the inner guide is driven, the other guide body 20 in the inner guide follows the movement.

[0029] Optionally, the frame 40 is equipped with two conveying modules 31, which can be belt conveying or chain conveying and are driven by a motor.

[0030] Further, two hook plates 23 are symmetrically installed on the guide body 20, and the crank arm roller 15 contacts the hook plates 23 for lifting drive, as shown in Figure 3 、 Figure 4 . The crank arm roller 15 moves in the hook plates 23. The hook plates cooperate with the crank arms to hook the crank arms during operation, playing a limiting role. And since the guide body itself is not wear-resistant, the hook plates and the lifting guide can use different materials to achieve the wear-resistant effect.

[0031] Preferably, to fix the position of the guide body 20 in the horizontal direction, as shown in Figure 3 、 Figure 4 , limiting frames 24 are symmetrically installed on both sides of the guide body 20. Limiting rollers 25 (or sliders) are installed at the outer ends of the limiting frames 24. A limiting mating body 41 is provided on the frame 40. The limiting rollers 25 are located in the groove formed between the two limiting mating bodies 41. Further, three groups of limiting rollers 25 are provided, as shown in Figure 3 . One group is located between the two limiting mating bodies 41, and the other two groups are respectively in contact with the outer sides of the two limiting mating bodies 41, further ensuring the stable lifting of the guide body 20.

[0032] It should be noted that the number of pallet types that can be adapted can be increased by increasing the number of guide bodies, and the corresponding lifting drive components can be increased.

[0033] Those skilled in the art should understand that the above description and the embodiments of the present invention shown in the drawings are only examples and do not limit the present invention. The object of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation and modification.
