Load on pillar increases；When increasing to above the rated service loads of pillar design, highly pressurised liquid in column is by hand handle
Safety valve in triple-use valve body is opened, and liquid spill, cavity pressure reduces, movable post uniformly lower contracting；It is lower than when pillar bears load
When nominal operation carries, safety valve is closed, and cavity liquid stops excessive；Therefore pillar service load remains that nominal operation carries
Lotus claims fast constant-resistance type pillar, and in whole work process, above-mentioned phenomenon repeats pillar, and pillar is made to be in work in constant-resistance condition
Make, to achieve the purpose that effectively to manage top plate.
(4) uninstall process：Unloading hand handle to be inserted into unloading port, rotation unloading hand handle forces valve pocket to move axially, thus
The feather valve in hand handle triple-use valve body is opened, liquid is discharged into old man, work of the movable post in self weight and reset spring through unloading in pillar
With lower retraction, reach drop column purpose.
The beneficial effects of the utility model are：
Suspension hydraulic prop designed by the utility model is fast constant-resistance type pillar, and structure is simple, easy to operate；Base body
Outer space will not be occupied, raw material is saved；Reduce the friction between plunger tube and oil cylinder in plunger tube movement, so that movable post
The impulse stroke of cylinder is bigger, bearing capacity is strong, stability and safety are good；Hand handle triple-use valve body had not only had the function of valve body but also had had
There are hand handle, multi-purpose valve, design not wasting space, and saving raw material, low manufacture cost.
