Description

Technical Field

[0001] This utility model relates to the technical field of loading and unloading equipment, and in particular to a logistics loading and unloading equipment. Background Technology

[0002] Loading and unloading refers to the process of loading or unloading goods into transport equipment by manpower or machinery at a designated location. The basic actions of loading and unloading include loading, unloading, stacking, warehousing, and outbound transportation, as well as short-distance transportation connecting the above actions. It is a necessary activity that arises with transportation and storage activities. In the logistics process, loading and unloading activities occur continuously and are carried out repeatedly.

[0003] For example, Chinese utility model patent CN202422371927.8 describes a logistics loading and unloading device that is easy to lift and lower. A servo motor drives a screw-connected adjusting block and connecting frame to move up and down along a fixed frame via a lead screw. The tilt angle of the conveyor is adjusted by the rotational engagement between the connecting frame and the conveyor, and the sliding engagement between the movable block and the fixed rod. However, the lead screw bears the weight of the entire fixed frame and the goods. If the lifting height is too large under vertical pressure, the lead screw is prone to Euler buckling deformation, which can lead to structural instability. Utility Model Content

[0004] The purpose of this utility model is to provide a logistics loading and unloading device to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

[0006] A logistics loading and unloading device includes a loading and unloading assembly. The loading and unloading assembly includes: a lifting assembly disposed on the top of a base; a first transmission belt disposed on one side of the lifting assembly; a second transmission belt disposed on one side of the first transmission belt and located on the top of the base; and an auxiliary support assembly disposed at the bottom of the first transmission belt. The auxiliary support assembly includes: a first connecting seat symmetrical to the bottom of the first transmission belt; a first support rod disposed on the first connecting seat and rotatably connected to the first connecting seat; a second connecting seat disposed at one end of the first support rod and rotatably connected to the first support rod; a first sliding plate disposed at the bottom of the second connecting seat; a first sliding groove cooperating with the second connecting seat disposed on the top of the base; a pin disposed on the first sliding plate and passing through the first sliding plate; and a slot symmetrical to the top of the base.

[0007] Optionally, a limiting plate is provided at the bottom of the first slide plate and is located inside the first slide groove.

[0008] Optionally, a fixing frame is provided on the top of the first slide plate and is sleeved on the outside of the first support rod. A spring is sleeved on the outside of the first support rod and is located inside the fixing frame.

[0009] Optionally, the outer side of the first support rod has symmetrical locking blocks, and the top of the fixing frame is provided with a locking groove that cooperates with the locking blocks.

[0010] Optionally, a second support rod is provided between the first support rods.

[0011] Optionally, the sliding assembly includes: a second sliding plate disposed on one side bottom of the second transmission belt, and a second sliding groove that cooperates with the second sliding plate provided on the top of the base.

[0012] Optionally, the base has symmetrical casters at its bottom.

[0013] Optionally, a threaded rod is provided on the base and extends through the base, and a pressing seat is provided at the bottom of the threaded rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] As the first transmission belt moves up and down, it works in conjunction with the slide plate and chute to drive the support rod to deflect to adapt to the height of the first transmission belt. When the slide plate moves to the predetermined position, it pushes the pin downward so that the pin is inserted into the predetermined slot to fix the slide plate. In this way, the fixed support rod supports the weight of the first transmission belt, the second transmission belt and the goods, reduces the weight borne by the lifting components and increases the stability of the logistics loading and unloading equipment when loading and unloading goods.

[0023] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0025] Given that in the current technology, the lead screw bears the weight of the entire fixed frame and the goods, if the lifting height is too large under vertical compression, the lead screw is prone to Euler buckling deformation, which can lead to structural instability.

[0026] like Figure 1-3As shown, this utility model embodiment provides a logistics loading and unloading device, including a loading and unloading assembly 1. The loading and unloading assembly 1 includes: a lifting assembly 12 disposed on the top of a base 11; a first transmission belt 13 disposed on one side of the lifting assembly 12; a second transmission belt 14 disposed on one side of the first transmission belt 13 and located on the top of the base 11; an auxiliary support assembly 2 disposed at the bottom of the first transmission belt 13, the auxiliary support assembly 2 including: a first connecting seat 21 symmetrical to the bottom of the first transmission belt 13; a first support rod 22 disposed on the first connecting seat 21 and rotatably connected to the first connecting seat 21; a second connecting seat 23 disposed at one end of the first support rod 22 and rotatably connected to the first support rod 22; a first sliding plate 24 disposed at the bottom of the second connecting seat 23; a first sliding groove 241 that cooperates with the second connecting seat 23 disposed on the top of the base 11; a pin 25 disposed on the first sliding plate 24 and passing through the first sliding plate 24; and a slot 251 symmetrical to the top of the base 11.

[0027] In use, the lifting assembly 12 is activated according to the loading and unloading height to adjust the height of the first transmission belt 13 and the inclination of the second transmission belt 14. While the first transmission belt 13 moves up and down, it works in conjunction with the first slide plate 24 and the first slide groove 241 to drive the first support rod 22 to deflect to adapt to the height of the first transmission belt 13. When the first slide plate 24 moves to the predetermined position, the pin 25 is pushed down so that the pin 25 is inserted into the predetermined slot 251 to fix the first slide plate 24. Thus, the first support rod 22, after being fixed, supports the weight of the first transmission belt 13, the second transmission belt 14 and the goods, reducing the weight borne by the lifting assembly 12 and increasing the stability of the logistics loading and unloading equipment when loading and unloading goods.

[0028] Furthermore, a limiting plate 26 is provided at the bottom of the first slide plate 24 and is located inside the first slide groove 241 to limit the first slide plate 24 and prevent the first slide plate 24 from detaching from the inside of the first slide groove 241.

[0029] Furthermore, a fixing frame 27 is provided on the top of the first slide plate 24 and is sleeved on the outside of the first support rod 22. A spring 271 is sleeved on the outside of the first support rod 22 and is located inside the fixing frame 27. The elasticity of the spring 271 supports the stability of the pin 25 inserted into the slot 251, thereby increasing the stability of the pin 25 inserted into the slot 251.

[0030] Furthermore, the outer side of the first support rod 22 is symmetrically provided with locking blocks 28, and the top of the fixing frame 27 is provided with a slot 281 that matches the locking blocks 28. When it is necessary to remove the fixing of the pin 25, the pin 25 is pulled upward and rotated, so that the locking blocks 28 are inserted into the slot 281 to fix the position of the pin 25, thus avoiding the need for the staff to continuously pull the pin 25 upward to remove the fixing of the pin 25.

[0031] Furthermore, a second support rod 221 is provided between the first support rods 22 to support the two sets of first support rods 22, thereby increasing the stability of the first support rods 22 and preventing the first support rods 22 from shifting laterally.

[0032] Furthermore, the sliding assembly 15 includes: a second sliding plate 151 disposed on the bottom side of the second transmission belt 14, and a second sliding groove 152 provided on the top of the base 11 to cooperate with the second sliding plate 151, so that the second transmission belt 14 is slidably connected to the base 11, and the second transmission belt 14 moves with the first transmission belt 13 as it rises and falls.

[0033] Furthermore, the bottom of the base 11 is symmetrically equipped with casters 16, which facilitates the movement of the logistics loading and unloading equipment.

[0034] Furthermore, a threaded rod 17 is provided on the base 11 and extends through the base 11. A pressing seat 171 is provided at the bottom of the threaded rod 17. By rotating the threaded rod 17, the rotating threaded rod 17 drives the pressing seat 171 to move downward and press the ground, thereby increasing the stability of the logistics loading and unloading equipment.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
