The connecting link 7 parallel with worktable 1 fixedly arranged between two pillars 6, by turning axle 8, two frame leg 8 tops of telescopic leg are installed respectively in the both sides of the middle part of connecting link 7 Width and all can rotate around turning axle; Frame leg 8 is in order to make worktable 1 maintenance level on Width by adjusting self length; Pillar 6 bottoms are equipped with fixedly slip foot pad 9, fixedly on the slip foot pad 9 pulley 16 are installed, and pulley 16 can slide at rail; Slip foot pad 9 arranged outside have the top to have the clamp screw 2 of vertical brake(-holder) block 17, and clamp screw 2 is used for rotation drive brake(-holder) block 17 and withstands the rail side, thereby slip foot pad 9 is locked on the rail.
Worktable 1 is provided with coordinate setting device 12, and coordinate setting device 12 adopts conventional odometer, is used for calculating the coordinate of worktable loca position and being presented at the display screen that self has by odometer; Worktable 1 upper surface is provided with circular bubble 13 and is used for whether level of judgment task platform 1; Worktable 1 upper surface is provided with the guide rail consistent with the worktable length direction, and being equipped with on the guide rail can be along the total powerstation mounting seat 11 of guide rail slip, and total powerstation mounting seat 11 is fixing by the vertical clamp screw 3 that is arranged on the worktable 1; Be provided with the second accurate graduated scale 15 at the edge of worktable 1 length direction, the zero graduation of the second accurate graduated scale 15 is concordant with the center line of the described pillar 6 that is connected worktable 1 by turning axle, the mid point of the middle scale of the second accurate graduated scale 15 between two pillars, 6 center lines; Total powerstation mounting seat 11 is provided with position line 14; The initial position of total powerstation mounting seat 11 is middle scales of position line 14 being aimed at the second accurate graduated scale 15; When needs changed the position of total powerstation mounting seat 11 on guide rail, loosening clamp screw 3 made total powerstation mounting seat 11 drive total powerstations and moves to position line 14 and aim at new scale and lock clamp screw 3 then and get final product.The Wince total powerstation is installed on the worktable 1 by total powerstation mounting seat 11.
When the orbital plane of two tracks formations is out-of-level, in order to guarantee the total powerstation operate as normal, need to adjust worktable 1 place planar horizontal, thereby specific practice is to adjust the length of expansion link 4 place pillars 6 indirectly by the height of adjusting expansion link 4, until worktable 1 place planar horizontal; After expansion link 4 is adjusted, apart from d, superelevation is used for calculating total powerstation mounting seat 11 at the scale of the second accurate graduated scale 15 of the mobile back of guide rail position line 14 indications apart from d to the scale value of the first accurate graduated scale 10 concordant with the upper edge of its place pillar 6 as superelevation.
Use the utility model as follows to the operation that the quick setting-out automatic measurement system of railway tunnel contact net tie point carries out setting-out:
Step 1: foot rest is installed and it is moved to the survey station point;
Foot rest is erected on the rail at place, certain known point position and with the Wince total powerstation and is installed on the total powerstation mounting seat 11, position line 14 is aimed at the middle scale of the second accurate graduated scale 15; Top contact worktable 1 lower surface of expansion link 4 place columns 6; Initialization coordinate setting device 12 is also imported foot rest and is set up the known point coordinate at place in coordinate setting device 12, survey crew promotes the some position that the direction of foot rest along track to the contact net tie point C point (coordinate is known) for the treatment of setting-out slides into certain and tie point C point intervisibility, as backsight point A point, coordinate setting this moment device 12 shows the coordinate (x that backsight point A is ordered with this point
A, y
A, z
A); Survey crew promotes foot rest to be continued to slide, the difference that the x coordinate that the x coordinate that shows on the Real Time Observation coordinate setting device 12 and y coordinate and tie point C are ordered and y coordinate are corresponding stops slip when all increase tendency occurring, with this halt as survey station point B point, locking clamp screw 2, coordinate setting this moment device 12 show survey station point B point coordinate (x
B, y
B, z
B).
Step 2: according to orbital plane level whether, adjust foot rest and make worktable 1 level and total powerstation be positioned at naturally on the center line of two rails;
(1) when the orbital plane level, as shown in Figure 6, the circular bubble 13 of the length of survey crew adjustment rack leg 8 on worktable 1 is placed in the middle, guarantees worktable 1 level, and this moment, total powerstation was positioned on the center line of two rails naturally;
(2) when orbital plane is out-of-level, the automatic measurement mechanism position can't correspondence coordinate on the spot, need the movement automation measurement mechanism to make the worktable level, because in the adjustment process, therefore total powerstation also needs to adjust the position of total powerstation mounting seat 11 on worktable 1 along with the movement of worktable 1 has been offset the mid point of two rail vertical join line; Concrete adjust as follows: referring to Fig. 4,7, the length of survey crew adjustment rack leg 8, to regulate the positions of expansion link 4 pillar 6 in placed in the middle until circular bubble 13 for loosening clamp screw 5 simultaneously, tightens clamp screw 5, assurance worktable 1 level; First accurate graduated scale 10 high scales that read on the expansion link 4 are zero as the initial value of superelevation apart from the d(superelevation apart from d, and namely the value of d is zero under the horizontal situation of orbital plane), measure the foot rest height H; Import wire spacing l in two rails by the interface to total powerstation then, superelevation is apart from d, the foot rest height H, and total powerstation utilizes formula 1 to calculate scale a and is presented on the interface; Survey crew moves total powerstation mounting seat 11 and aims at scale a until position line 14, makes total powerstation be positioned on the center line of two rails, locks clamp screw 3 then;
A=cos (arctand/l) * l/2-sin (arctand/l) * H (formula 1)
Wherein, d is the superelevation distance, and initial value is zero, and l is wire spacing in two rails (length of MN), and H is the foot rest height.
Step 3: measure and setting-out;
Referring to Fig. 5, Fig. 6 and Fig. 7, survey crew is measured the high h of instrument, and imports layout point C point coordinate (x by the interface to total powerstation
C, y
C, z
C), the limit difference M that sets among the high h of instrument, engineering
0Total powerstation calculates steering angle α by formula 2 and is presented on the interface; Survey crew turns over steering angle α (see figure 5) after making total powerstation aiming backsight point A, obtains the vertical plane at place, contact net tie point point position this moment, also is 2 determined perpendiculars of B, C; Survey crew slowly rotates the total powerstation camera lens and makes its Continuous Observation in fixed vertical plane, obtain many group measurement data (comprise survey the survey of establishing angle β and its correspondence establish distance b) in the observation process, total powerstation is surveyed every group in real time and is established data substitution formula 3, and total powerstation is reported to the police when formula 3 is set up; Stopping to measure and record this group this moment surveys the survey of establishing angle β and its correspondence and establishes distance b; Total powerstation is got laser display and a bit be layout point on tunnel wall, and survey crew marks this point in tunnel wall, and setting-out finishes.
M=|cos β * b+h+sin(arctand/l) * l/2+z
