Description
Technical field
The present invention relates to a kind of arrangement for adjusting height, more specifically, it relates to a kind of wedge-shaped elevation and subsidence regulating device.
Background technology
When equipment is installed, because surface water Pingdu is bad, many times need to pad top block in appliance feet, so that
Equipment is steadily laid, and for the ease of adjusting bearing height, feet can typically carry out adjustable height regulation, enable a device to quickly pacify
Keep steady.Support base and the adjusting screw rod being vertically connected on support base are generally comprised using more feet at present, by turning
Dynamic adjusting screw rod realizes different height regulations, easy to adjust, but need when adjust feet and appliance feet is hanging,
And equipment is heavier, hanging operation inconvenience, and generally require repeatedly to adjust to adjust to arrive 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 does not apply to.
Chinese patent publication No. CN102241377A, disclose a kind of dress of adjusting tool foot supporting plate heights through mechanical drive
Put, including footing plate, PTO, transmission device and lowering or hoisting gear, transmission device include turbine, worm screw, first gear
And rack, lowering or hoisting gear include second gear and screw rod, PTO outputs power to turbine and worm screw, turbine and
One gear is connected, and first gear is meshed with rack, and rack is meshed with second gear, and internal thread and the screw rod of second gear are nibbled
Close, screw rod is connected with the footing plate.This programme adjusts the mechanism of lathe backing plate height by using Mechanical Driven so that feet
Plate can be lifted arbitrarily to adjust height.But his bearing capacity is limited, progress bearing height tune in appliance feet is not useful in
Section.
The content of the invention
Instant invention overcomes appliance feet arrangement for adjusting height to adjust operation inconvenience, and bearing capacity is poor, and support stationarity is not
Good deficiency, there is provided a kind of wedge-shaped elevation and subsidence regulating device, its lift adjustment is easy to operate, and bearing capacity is strong, and support is steady
Reliably.
In order to solve the above-mentioned technical problem, the present invention uses following technical scheme：A kind of wedge-shaped elevation and subsidence regulating device, including
