Description
Technical field
The present invention relates to construction equipment field, in particular to a kind of dismountable building site temporary up-down mechanism.
Background technology
When modern architecture is constructed, it can usually use and arrive tower wagon or lowering or hoisting gear, staff or material transportation are arrived
Higher position, so as to save manpower.Such as need to use tower wagon progress work high above the ground when setting up cable in building site, or it is right
Some interior of building top surfaces spray emulsion paint, or need to use in tower wagon progress reinforcing bar when bridge construction processes box beam
Stress test, therefore be frequently necessary to use with certain altitude and moveable equipment on building site.
But the tower wagon constant height usually used in the prior art cannot be adjusted, cause its usage scenario less, fit
Answering property is poor.And the liftable mobile platform of in general mostly uses hydraulic shear cutter frame structure.Described hydraulic shear cutter frame structure
Although the regulation of certain altitude can be carried out, it is easily swung because of its architectural characteristic in rise, and height is higher
Amplitude of fluctuation is bigger, once later maintenance maintenance effect is poor, can also there is certain potential safety hazard；And use hydraulic pressure scissors
When frame structure is lifted, the thrust of hydraulic jack is not steady state value, and hydraulic jack load is larger when first section raises, once lifting
When article on platform is heavier, certain damage can be caused to hydraulic jack.
The content of the invention
