Detailed description of the invention
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that the understanding of technician of the same trade:
As shown in figures 1 to 6, mark 1-20 in figure to be respectively: leveling support 1, support bar 2, leveling bar 3, leveling bar 4, expansion coupling 5, positioner 6, connector 7, circular bubble 8, bubble tube 9, hinge 10, stop screw 11, limited block 12, telescopic shaft 13, trimming hand wheel 14, external member 15, interior stay tube 16, main body 17, slide block 18, spring 19, briquetting 20.
Embodiment: as shown in Figure 1, 2, the forced centering foot rest superstructure measured for the optional centering CPIII in railway bed location in the present embodiment comprises leveling support 1, and the top of leveling support 1 connects the prism supporting CPIII and measure.Support bar 2, leveling bar 3, leveling bar 4 is provided with bottom leveling support 1, each body of rod utilizes determine at 3, and the principle of plane determines a plane for leveling support 1, and make this planar horizontal by adjustment two leveling bars, thus make the measuring prism on leveling support 1 and top thereof keep vertical.Support bar 2 is fixedly connected on the center of leveling support 1 bottom surface as the fixed point in 3 o'clock.Leveling bar 3 and leveling bar 4 form respectively by hinge 10 and leveling support 1 and are rotatably assorted, and leveling bar 3 and leveling bar 4 can be rotated around leveling support 1 respectively by hinge 10, support to coordinate support bar 2 pairs of leveling supports 1.The shaft of leveling bar 3 and leveling bar 4 is respectively arranged with expansion coupling 5 and positioner 6, expansion coupling 5 is for adjusting the shaft length of leveling bar 3 or leveling bar 4, thus push-and-pull is carried out to leveling support 1, realize the plane adjustment of leveling support 1, and positioner 6 is for the locking of expansion coupling 5, avoid expansion coupling 5 cannot ensure the stable support state of leveling pole pair leveling support 1 after stretching.The body of rod axis angle of leveling bar 3 and leveling bar 4 is rectangular, can from perpendicular both direction push-and-pull leveling support 1 to adjust its surface levelness both making.
As shown in Figure 3,4, the surface of leveling support 1 is fixedly connected with connector 7, circular bubble 8 and bubble tube 9, wherein the outer profile size of connector 7 and the portion that the is connected matching size of its top measuring prism share in being connected and fixed top measuring prism, and circular bubble 8 and bubble tube 9 are respectively used to the levelness showing leveling support 1 surface.Angle between two bubble tubes 9 is vertical, to show the levelness in the perpendicular both direction of leveling support 1.When three bubble show respectively leveling support 1 be in level time, measuring prism can be connected on connector 7 by technician.
As shown in Figure 5, the expansion coupling 5 in the present embodiment comprises stop screw 11, limited block 12, telescopic shaft 13, trimming hand wheel 14, external member 15, interior stay tube 16.Limited block 12 is fixed on the two side ends head of telescopic shaft 13 by two screws 11 respectively.It is inner that telescopic shaft 13 is sleeved on stay tube 16 in upper and lower two, coordinates formation to be connected and fixed between telescopic shaft 13 with interior stay tube 16 by internal and external screw thread.Connecting axle 13 is provided with trimming hand wheel 14 and external member 15, trimming hand wheel 14 is rotationally connected axle 13 for technician, make it flexible from interior stay tube 16 by threaded engagement, realize the length adjustment of leveling bar 3 and leveling bar 4, external member 15 is for carrying out spacing to trimming hand wheel 14.Be arranged on the outer profile size of outer profile size slightly larger than telescopic shaft 13 of the limited block 12 of connecting axle 13 two ends head, after telescopic shaft 13 screws out elongation in interior stay tube 16, can stop that telescopic shaft 13 departs from interior stay tube 16.Interior municipal administration 16 is arranged on the shaft of leveling bar 3 and leveling bar 4.
As shown in Figure 6, leveling bar 3 is provided with the positioner for carrying out locking positioning to leveling bar 3, when the length of leveling bar 3 needs to adjust, unlocking locating device, makes leveling bar 3 carry out length adjustment by the expansion coupling 5 on its body of rod; And when the length adjustment of leveling bar 3 is complete coincidence measurement needs time, locking positioning device, makes the length of leveling bar 3 be fixed, measurement misalignment when avoiding measuring caused by leveling bar 3 change in length.Positioner is made up of main body 17, slide block 18, spring 19, briquetting 20, is wherein provided with a cambered surface in main body 17, and the inner surface of two pieces of slide blocks 18 coincide adaptive respectively with this cambered surface, form between the two and be slidably matched.Be connected and fixed by spring 19 between two pieces of slide blocks 18.Form inclined-plane between the outer surface of briquetting 20 and slide block 18 to fit.Leveling bar 3 is clamped between slide block 18 and briquetting 20.In use, by briquetting 20 to pressing down, the inclined-plane of briquetting 20 can extrude two pieces of slide blocks, 18, two pieces of slide blocks 18 and can move in opposite directions along the cambered surface of main body 17, and now leveling bar 3 unlocks, and realizes freely adjusting of its length.Unclamp briquetting 20 after length adjustment completes, now spring 19 resets, and two pieces of slide blocks 18 move upward until coordinated the locking to leveling bar 3 with briquetting 20 along the cambered surface of main body 17.Leveling bar 4 is also provided with the positioner identical with on leveling bar 3.
The present embodiment is in the specific implementation: on the basis of three-point fix plan view, will be more fixing, its advantage be avoid 3 all undetermined situation time, technician need influence each other at 3 under, back and forth adjust 3 until the level of leveling support 1; In addition length is carried out to support bar 2 and fix the height measuring prism centers by prism, and then the CPIII survey mark height of fixing centering foot rest can be extrapolated, thus facilitate level gauge to carry out dimensional measurement.
Forced centering foot rest can be directly installed on CPIII measurement point or coordinate various survey mark to use.This survey mark needs offer the adaptive connecting hole that to match with the bar footpath of support bar 2.
Although elaborate the design of the utility model object and embodiment with reference to accompanying drawing with above-described embodiment, but those of ordinary skill in the art can recognize, the essence of above-described embodiment is determined a bit fixing in plan view at 3, realize the centering leveling of forced centering foot rest, make the survey data of measuring apparatus more accurate.So under the precondition not departing from claim limited range, still various improvement and conversion can be made to the utility model, as: the specific constructive form of expansion coupling 5, the level gauge form of structure, kind etc. on leveling support 1 surface, therefore do not repeat one by one at this.
