Description

A lifting platform

Technical Field

The utility model relates to the field of lifting devices, in particular to a lifting platform.

Background Art

Lifting devices are widely used in life and industrial production. People can use lifting devices to transport heavy objects to places that are beyond the reach of some people. Some existing small lifting devices cannot carry heavy objects and have a small lifting range. Some lifting devices with good load-bearing effect and large lifting range usually have many components, complex structure, and are not easy to operate.

A lifting platform provided according to patent application number CN201310659748.8 includes a load plate, a bottom plate, a transmission assembly and at least one group of lifting assemblies; the load plate is arranged on the upper side of the bottom plate; the lifting assembly is arranged between the load plate and the bottom plate; each group of lifting assemblies includes two support arms cross-hinged with each other; the two ends of the transmission assembly are respectively connected to the ends of the two support arms; the lifting platform of the invention drives the load plate to rise and fall through the cooperation of the lifting assembly and the transmission assembly; the overall structure is simple, easy to operate, has a good load-bearing effect, and has a smooth transmission.

There are still some shortcomings in this patent application. The device adopts a scissor fork structure. When the lifting starts, the scissor fork structure contracts to increase the height, which will change the support point of the lifting platform, causing the two ends of the lifting platform to be farther and farther away from the support point. The edges are easily shaken due to the force, and it is difficult to meet the smoothness and stability during plane operation. A lifting platform is needed to solve these problems.

Beneficial effects:

The new model adopts a push rod to push the push shaft to rotate in the shaft sleeve, changing the height of its free end and then changing the height of the lifting frame to achieve lifting. During the lifting and lowering, the distance between the support rods remains unchanged, avoiding the problem of unstable edges in the cited patent. Generally, operations on the lifting platform require greater starting force and supporting force in the lowest and highest situations. When the new model is in the highest and lowest states, the push rod is horizontal and has no vertical force component, so the thrust utilization rate is maximized, saving resources. The new model fixes the supporting structure from the top and bottom through two rods, the connecting rod and the sliding shaft fixing rod, so that the lifting of the device is more stable.
