Manual and electric integrated mobile lifting work platform

Abstract

The invention relates to the technical field lifting machines, in particular to a manual and electric integrated mobile lifting work platform. The manual and electric integrated mobile lifting work platform comprises a mobile bearing trolley and a lifting platform body. The lifting platform body is fixed to the bearing trolley and comprises a lifting mechanism and a driving mechanism. The lifting mechanism is a shear type lifting mechanism. The driving mechanism comprises an electric driving end, a manual driving end and a wedge-shaped block device. The electric driving end and the manual driving end are connected with the wedge-shaped block device. The wedge-shaped block device is connected with the shear type lifting mechanism. The manual and electric integrated mobile lifting work platform has the beneficial effects that the structure is simple, cost is low, two driving manners are achieved, and the use reliability of equipment under an external field working condition can be ensured; and the mechanical lifting platform body is adopted, so that the equipment size and weight are reduced, stability and precision are improved, more advantages are achieved during assembly and butt joint, and the manual and electric integrated mobile lifting work platform is suitable for being applied and popularized.

Description

technical field [0001] The invention relates to the technical field of lifts, in particular to a manual and electric integrated mobile lifting work platform. Background technique [0002] Due to the characteristics of flexible transfer and vertical transportation, the mobile lifting work platform is widely used in the fields of production, processing, assembly and maintenance. At present, there are two types of mobile elevating work platforms, manual and automatic, and users can choose the appropriate type according to the working conditions and cost. However, when related operations are carried out outside the factory or other field, the automation equipment is sometimes not completely reliable. If a fault occurs or the power supply is insufficient, it will be a big trouble for the engineering personnel. [0003] Due to its compact structure, large bearing capacity, and strong passability of the drive device, the scissor lift platform is widely used in warehousing logistic...

AI Technical Summary

Problems solved by technology

However, the structure of connecting rod drive is generally low in precision due to the relatively complicated transmission mechanism.

Secondly, when the lifting stroke is large, the size of the linkage mechanism becomes significantly larger, which is not suitable for occasions with high space requirements.

Although the structure that uses the lead screw to directly drive the movement of the scissor arm has improved precision and reduced volume, due to the limitation of its driving position and driving form, the load-carrying capacity of the lifting platform is obviously lower than other structural forms.

On the other hand, the current scissor lift platform in the form of mechanical transmission generally has a high minimum lifting height, and the scope of use has great limitations.
