Companion ladder 4 adopts two-segment types, and the net of bottom one joint is closeer, and the net on top is thinner, the companion ladder two ends respectively be provided with 4 symmetrical mounting holes 41, the position is on middle beam and base cross members respectively.Steel rope 5 passes the mounting hole 41 of middle beam and base cross members successively, and mounting hole 41 is installed with steel rope 5 usefulness wire line hitchs 7.Wire line hitch 7 is resilient " youngster " fonts, above passing and behind two following mounting holes 41, is stuck on the following mounting hole 41.In the time will unloading down, clutch sling, can from the hole, pass.
In conjunction with Fig. 9, angle measurement equipment 6 is housed also on the companion ladder 4.Angle measurement equipment 6 comprises base 63, and semisphere transparent housing 62 is contained in base 63 tops, and liquid is filled in semisphere transparent housing 62 inside, floats the white floating debris 61 that has to scribble fluorescent material on the liquid, and its diameter is 2mm; Be parallel on the semisphere transparent housing 62 and be evenly distributed with the first scale 65, be evenly distributed with the second scale 66 on the circumference outer ring that is connected with semisphere transparent housing 62 on the base 63.
In conjunction with Figure 10, the first scale 65 along semisphere transparent housing 62 arcs walk downward from the top range of readings be 0～90 the degree.The first scale 65 is parallel at hemisphere face and evenly distributes, and is discontinuous.The first scale 65 minimum scales are 2mm.
In conjunction with Figure 11, the second scale 66 is marked on the base around semisphere transparent housing 62 1 circles, and range of readings is from 0～360 degree, and minimum scale is 2mm.The second scale 66 evenly distributes on the base circle, and the warp of being well-distributed scale index line is arranged on semisphere transparent housing 62 hemisphere faces, and is corresponding with the second scale 66.
There is bolt 64 base 63 belows, can with have mount pad hole equipment and carry out bolt and be connected, according to white floating debris 61 positions, read the angle that rolls deflection by arc the first scale 65, read the direction that rolls deflection by circular the second scale 66 again.
The scale mark of the first scale 65 and the second scale 66 all contains fluorescent material, and visbility also can clearly show when low.
The principle of work of angle measurement equipment 6 is as follows:
In the sphere of a smooth no concave-convex, if the inner filled with fluid of sphere, and the impact that exists a white floating debris, white floating debris to be subject to buoyancy always swims in the extreme higher position in the spheroid, and this point then is the point of contact P of sphere and horizontal surface.So at this constantly, the point at the centre of sphere and place, the white floating debris center L that draws a straight line, by line L make horizontal surface vertical surface S (360 any directions of spending can).Can suppose that the cross section that S face and ball intersect is S1, as shown in figure 12.As long as being in the rotation of static (perhaps not exclusively static, white floating debris rocks when smaller) section S 1 does not affect and floats to the vertex position on the white floating debris.According to this principle, can be at the sphere calibrate, thus show the rotation amplitude α (namely angle) of sphere by white floating debris with respect to the position of sphere scale, as shown in figure 13.Because spheroid is the same in the rotation situation through the arbitrary section S1 (any direction is arbitrarily angled) in the center of circle, so the white floating debris come-up principle in this cross section can apply on whole spheroid or upper half spheroid, the measurement at angle of inclination is then set up on three dimensional space equally.Then as shown in figure 14, can determine its circumferential orientation around spheroid one circle, indicate circumferential scale by the warp on ball surface; As shown in figure 15, can determine its angle of inclination by parallel indication, indicate angle of inclination on the cross section by the parallel on ball surface.Overall schematic such as Figure 16 after both unifications, warp, parallel cross-distribution are on sphere.
During use, first angle measurement equipment 6 is installed on the companion ladder 4 by bolt 4, installs when connecting, not necessarily will tighten fully, as long as to good positive dirction position.Behind companion ladder 4 position stabilities, can begin to read registration.At first, when measuring companion ladder 4 orientation by angle measurement equipment, be indexed to the second scale 66 by the warp of white floating debris 61 positions and can read orientation angles with respect to companion ladder 4 positive dirctions, then this scale is the orientation with respect to companion ladder 4.After stable, the weft strand by white floating debris 61 present positions causes the angle of inclination that the first scale 65 is read the position again, and suitably the rotational angle measurer makes white floating debris 61 adjust to the position of parallel index, runs through registration, again goes back to again.Note, during the second scale 66 reading, need companion ladder 4 that certain angle of inclination is arranged, otherwise white floating debris 61 can be in zero point, then can not read registration by warp.So when the orientation of adjusting companion ladder 4 and angle, should adjust first the orientation, adjust again the angle of inclination.
A kind of multiple degree of freedom jacking system that the utility model provides is the cart structure of a four-wheel when installing condition not, the guide rail that second stage platform stretches out is handrail, and a roller is arranged on each support of supporting bracket, companion ladder has been installed on the fourth stage platform, and rises in the position of top.Supporting bracket up passes first order platform, and the installation fitting that other some are similar to bearing support is placed in the companion ladder, and whole device is deflation integral body together, is shaped as a four-wheel go-cart.
During installation, all installation fittings can be put in order out, select the position that the road surface will be firmly grasped, bearing support is installed on the road surface.Positioning instant then can directly be stretched with support claw in common level land can.Be not suitable for the mounting support bearing if any the slope, then can be installed in the supporting bracket bottom with rubber coating.One section of bearing support or many sections support claws can be pricked in ground on the soft road surface of soil property.
Spherical pair with supporting bracket and bearing support couples together again, and roller is packed up.This moment can begin the rise of primer fluid pressure device supporting bracket, first the fine setting, allow four stent length quite after, allow again four supports rise to synchronously desired height.Can control at last motor puts down companion ladder.
During use, climb up companion ladder, after stable, judge the equilibrium condition of installation site according to angle measurement equipment, carried out again the fine setting of four supports by fluid control.Control electric machine rotation, companion ladder rises to extreme higher position (this moment, companion ladder only had half to be higher than support platform, half was arranged still inside) again.By the rotation of second stage platform, the slippage of the 3rd platform and the continuous position as required of hydraulic lifting of Siping City's platform, change the position of three directions in space three-dimensional space at last.
After using, return to uninstalled position, notice that handrail is consistent with the direction furnishing of roller.Then can be to promote, to lift, to drag or motor the form such as drives voluntarily and transports.
