Description
Technical field
The present invention relates to a kind of height adjustment device, more specifically, it relates to a kind of wedge shape elevation and subsidence regulating device.
Background technique
In equipment installation, since surface water Pingdu is bad, many times need to pad top block in appliance feet, so that
Equipment is steadily placed, and for the ease of adjusting bearing height, feet can generally carry out adjustable height adjusting, enable a device to quickly pacify
It keeps steady.At present using the adjusting screw rod that more feet generally comprises support base and is vertically connected on support base, by turning
Dynamic adjusting screw rod realizes different height adjustments, easy to adjust, but adjust when need feet and appliance feet is hanging,
And equipment is heavier, it is hanging inconvenient, and generally require repeatedly to adjust just to be adjustable suitable position, operation is very not
Just.This kind of feet bearing capacity is also limited, and support stationarity is bad, to many large scale equipments and is not suitable for.
Chinese patent publication No. CN102241377A, discloses a kind of dress of adjusting tool foot supporting plate heights through mechanical drive
It sets, including footing plate, power output device, transmission device and lifting device, transmission device includes turbine, worm screw, first gear
And rack gear, lifting device include second gear and screw rod, power output device outputs power to turbine and worm screw, turbine and
The connection of one gear, first gear are meshed with rack gear, and rack gear is meshed with the second gear, and internal screw thread and the screw rod of second gear are nibbled
It closes, screw rod is connect with the footing plate.This programme adjusts the mechanism of lathe backing plate height by using Mechanical Driven, so that feet
Plate can arbitrarily go up and down to adjust height.But his bearing capacity is limited, is not useful in progress bearing height tune in appliance feet
Section.
