Description

Technical Field

[0001] The utility model relates to material transportation, in particular to a lifting device. Background Art

[0002] Logistics refers to the whole process of planning, implementing and managing the transportation, storage and distribution of raw materials, semi-finished products, finished products or related information from the place of production to the place of consumption of the goods in order to meet the needs of customers. When transporting materials, lifting devices are needed to lift the materials to the corresponding height.

[0003] Existing technologies, such as: a positioning and lifting device for smart materials with announcement number CN217804794U, which places the logistics goods on the placement plate and then applies thrust to the armrest, and the armrest drives the trolley body to move. At this time, the rotating shaft and the auxiliary wheels roll in the inner cavity of the arc groove until they move to the specified position. When the logistics goods are transported and the height needs to be adjusted, the micro stepper motor is controlled to rotate, and the output shaft of the micro stepper motor drives the threaded rod to rotate. At this time, the threaded rod drives the fixed block to move. At the same time, the fixed block drives the placement plate to move until it is adjusted to a suitable height, thereby facilitating the height adjustment of the logistics goods placed on the placement plate, and the adjusted height is accurate.

[0004] There are other existing technologies such as: CN214653331U, an automatic lifting device for cargoes used in logistics transportation

[0005] CN208948760U, a lifting device for logistics equipment

[0006] However, the above and other typical existing technologies still have certain problems when used:

[0007] 1. When in use, the logistics lifting device will pass through uneven roads, which will cause collisions between the logistics and the support plate, resulting in damage to the logistics parts. It cannot provide cushioning and protection for the logistics parts during transportation, which reduces the quality of protection for the logistics parts and limits the applicability of the lifting device.

[0008] 2. The lifting device only relies on the cylinder for lifting support when in use, and the support method for logistics is single. When the cylinder is accidentally damaged, it will cause the logistics to fall from the top, causing damage to the logistics and there is a risk of hitting the staff. The lifting support effect of the logistics is poor. Utility Model Content
