Supporting leg and universal wheel for heavy equipment

Abstract

The invention provides a supporting leg and a universal wheel for heavy equipment, which relate to the design and innovation of supporting and transporting components of the heavy equipment. A multi-ball type universal wheel is fabricated by evenly distributing a plurality of ball roller wheels on the same circumference of the same wheel disc; a spiral type supporting leg is arranged in the middle of the multi-ball type universal wheel; a layer of thick high-performance damping cushion is arranged above the multi-ball type universal wheel and is fixed under an equipment bracket by a plurality of symmetrically-distributed bolt washers. When extending out, the spiral type supporting leg replaces the multi-ball type universal wheel to play a role in supporting; and when the spiral type supporting leg retracts, the multi-ball type universal wheel restores the transporting function. The problems that the universal wheel has a large size, is easy to deform due to long-term stress, cannot adjust the height and the level of the equipment and the like are solved. The high-performance damping cushion can effectively absorb vibrations when the equipment runs, and can further reduce uneven stresses and vibrations of the roller wheels caused by uneven ground surface when the equipment is used for transportation. Thus the high-performance damping cushion is a caster wheel component with comparatively complete functions for the heave equipment.

Description

Technical field [0001] This invention relates to the design and innovation of heavy equipment support and transport components. Background technique [0002] At present, industrial casters and universal casters produced by professional manufacturers at home and abroad are widely installed on trolleys, furniture, seats, and small and medium-sized medical equipment and electromechanical equipment that must be frequently moved as standard parts or general parts. , life and production have brought great convenience. However, for many heavy equipment that are large in size and heavy in weight, do not need to be fixed by machine foot bolts, and are less mobile, there is a lack of a caster that is mainly supported and can be easily moved occasionally. The existing standard or general-purpose casters mainly for transportation obviously cannot take on their heavy responsibilities: first, the casters are prone to permanent deformation due to long-term static heavy loads; second, the ...

AI Technical Summary

Problems solved by technology

However, for many heavy equipment that are large in size and heavy in weight, do not need to be fixed by machine foot bolts, and are less mobile, there is a lack of a caster that is mainly supported and can be easily moved occasionally.

The existing standard or general-purpose casters mainly for transportation obviously cannot take on their heavy responsibilities: first, the casters are prone to permanent deformation due to long-term static heavy loads; ; The third is that the height and level cannot be adjusted, and it is difficult to meet the installation and use requirements of the equipment

With the development of society, the use of heavy equipment in all walks of life continues to increase. If you occasionally move heavy equipment indoors, it is definitely uneconomical and inconvenient to use large lifting and transportation equipment.
