A junction connected by lifting cylinder 230, thus by changing bracket 210 and 220 bracket of workbench at above-mentioned three
210 spacing distance can play the corrective action to 220 levelness of workbench.
Corresponding with the above-mentioned setting of three lifting cylinders 230 outside it, in the present embodiment, bracket 210 further includes three
It is a to the fixed supporting leg extended to form far from 210 center position of bracket, uniform intervals between three fixed supporting legs.Above-mentioned three
Lifting cylinder 230 is arranged in a one-to-one correspondence respectively with three fixed supporting legs, plays the work for being connected and fixed supporting leg Yu workbench 220
With.It can be played between support working platform 220 and adjustment workbench 220 and bracket 210 by lifting cylinder 230 as a result,
Distance and workbench 220 levelness effect.
Further, in an embodiment of the present invention, one end of lifting cylinder 230 is fixedly connected with workbench 220, is risen
The other end and the bracket 210 for dropping oil cylinder 230 are hinged.Or one end of lifting cylinder 230 and 220 fixed hinge of workbench, it rises
The other end of drop oil cylinder 230 is fixedly connected with bracket 210.
Specifically, referring to figure 4., during lifting cylinder 230 are arranged, lifting cylinder 230 can also pass through connection
Part 240 is connect with workbench 220.Wherein, connector 240 is fixed including first connecting portion 241, second connecting portion 242, first
Part 243 and the second fixing piece 244.First connecting portion 241 has the shape with the cooperation of the outer peripheral surface of workbench 220;Second connects
Socket part 242 has the mounting groove 245 of the cylinder body for accommodating lifting cylinder 230.First connecting portion 241 passes through the first fixing piece
243 are fixedly connected with workbench 220, and lifting cylinder 230 is fixed in mounting groove 245 by the second fixing piece 244.As a result,
To guarantee the mounting stability of lifting cylinder 230, especially stability of the increase bracket 210 to 220 supporting role of workbench.
Further, in other embodiments of the invention, it during being tested, is also spaced on the bracket 210
It is provided with multiple vacuum cylinders, vacuum cylinder enables underwater static test device to be attached to the bottom for providing adsorption capacity, and
It carries out providing counter-force when cone penetration test, guarantee test is normally carried out.Outside it, vacuum cylinder can pass through movable support rod and branch
Frame 210 connects, and movable support rod is for adjusting the distance between bracket 210 and vacuum cylinder.
In addition, controlling for the ease of the movement to above-mentioned movable support rod, it is additionally provided with inclination angle biography on the bracket 210
Sensor, obliquity sensor are used to measure the levelness of bracket 210.In order to be measured simultaneously by the levelness to bracket 210
Control the movement of movable support rod.
It should be noted that the effect of above-mentioned movable support rod is to adjust the levelness of bracket 210, the adjustment mode
It can be used cooperatively with the adjustment of the levelness of workbench 220.
Based on above-mentioned fixed frame levelling device 200, the invention also discloses a kind of fixed frame leveling method, which employs
Above-mentioned fixed frame levelling device 200 comprising following steps:
The levelness of workbench 220 is detected by the obliquity sensor being arranged on workbench 220;
Control lifting cylinder 230 adjust workbench 220 between bracket 210 at a distance from, until obliquity sensor detects
Workbench 220 is horizontal.
The working principle of the fixed frame levelling device 200 is:
The levelness of workbench 220 is detected by obliquity sensor, and then by multiple lifting cylinders 230 to bracket
The distance between 210 and workbench 220 are adjusted, and adjust workbench 220 to horizontal effect to play.Specifically
, the fixed frame levelling device 200 include bracket 210, workbench 220 and setting bracket 210 and workbench 220 it
Between multiple lifting cylinders 230.In addition, being additionally provided with obliquity sensor on workbench 220, can be surveyed by obliquity sensor
Measure the levelness of workbench 220.When workbench 220 is not in level, work is able to detect that by obliquity sensor
Make the levelness signal of platform 220, and the levelness signal by will test is collected and calculates, and then passes through control
The lifting cylinder 230 connecting with hydraulic device is controlled, and can be adjusted to the levelness of workbench 220.As a result, just
Can rapidly calibration platform 220 horizontal position.Simplify operating procedure, and is effectively shortened adjustment workbench 220
Time needed for levelness.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
