Referring to Fig. 1 and 2, it is made up of level components 3 and height gauge assembly 4, and the 1st, CAU;

Level components is, left end, right-hand member fixed block 36 that left end fixed block 32 is fixed on below the surveyor's staff 31 are fixed on the right-hand member below the surveyor's staff, when being placed on rail on direction surveyor's staff perpendicular to rail, the outside of left end fixed block abuts against the inboard of left side rail 2, just in time can insert limited block 33 between the outside of right-hand member fixed block and right side rail 5 inboards; For making slide block stable, above-mentioned chute 34 is established two, and each side indicates rule 35 in the both sides of chute, and promptly the upper surface at surveyor's staff has the centre zero scale chi, and every zero graduation to rule aligns with the outside of its left end fixed block;

Referring to Fig. 3, the height gauge assembly is made up of slide block 41 and vernier caliper 42 from bottom to top; Establish 34 li of two chutes that 411, two swallow-tail form slide rails of two swallow-tail form slide rails are embedded in surveyor's staff respectively below the slide block 41, do being slidingly matched with chute; Vernier caliper 42 is made up of blade 421 and vernier 422; Blade is square tube type, be positioned at the limb place at the square tube wall and open axial slit 4211, square tube with vertical be fixed on slide block above, its front indicates rule 4212, this rule 4212 is a datum line 412 with the extended line of the intersection of slide block, is marked on the slide block; Vernier 422 is column, the section configuration of its section configuration and blade compensates mutually, the inner chamber of vernier insertion blade above blade, the two is done and is slidingly matched, on blade, also be provided with the fastening bolt that allows vernier locate, protuberance 4221 on the vernier 422 protrudes from outside the axial slit 4211, vernier graduation chi 4222 is positioned on the protuberance, the top of vernier graduation chi 4222 protrudes from vernier, as surveying high reference edge 4223, one spill handle 4224 is arranged on protuberance one side, and finger stretches in the spill handle and can promote slide rule.

Using method is:

1. measure the deviate of center and the center between two rails of CAU

Referring to Fig. 4, measure A1 and A2 among Fig. 4 respectively, can draw the poor of the two, i.e. the deviate of the center between the center of CAU and two rails.Specifically be that the utility model is placed on the rail by mode shown in Figure 1, measure the B side that the people is positioned at Fig. 1, the height gauge assembly is moved under the CAU, be pulled upwardly slide rule, make the high reference edge 4223 of survey on the slide rule aim at upward intrinsic central screw 11 of CAU, the number of division that the datum line 412 on the slide block is aimed at surveyor's staffs is exactly the A1 value; Measure the opposite side that the people arrive surveyor's staff again,, the outside of fixed block 36 is abutted against the inboard of this side rail 5, limited block is inserted between the outside and rail 2 inboards of fixed block 32, repeat above-mentioned metering system, can obtain the A2 value the limited block taking-up.If A1-A2≤± 10mm, then CAU installs correct.Otherwise incorrect, reinstall CAU according to difference, up to A1-A2≤± 10mm.

2. measure the vertical range Z of CAU bottom surface and rail upper surface

Referring to Fig. 5, by measuring method 1., upwards promote the bottom surface of vernier to CAU, make and survey the bottom surface that high reference edge 4223 is met CAU, the reading on the vernier caliper adds that a definite value (this definite value is meant that the surveyor's staff lower surface is the distance between the zero graduation of rail upper surface and vernier caliper) is exactly the vertical range of CAU bottom surface and rail upper surface.Above-mentioned in the present embodiment definite value is 175mm.If it is Z that the reading on the vernier caliper adds the 175mm sum, in the 137-276mm scope, the deviation of permission is in 10mm, and then CAU installs correct.

3. measure the degree of tilt of CAU

Referring to Fig. 6, by 2. measuring method, T1 in the survey sheet 6 and the value of T2 respectively earlier are converted into the pitch angle of CAU again.In the present embodiment, because of the length of CAU is 410mm, during according to T1=T2 ± 7mm, the pitch angle is 1 ° and measures T1 and T2, and is converted into the pitch angle.If degree of tilt in 4 °, is then installed correct.

4. measure the elevation angle that CAU installs

Referring to Fig. 7, by 3. measuring method, P1 in the survey sheet 7 and the value of P2 respectively earlier are converted into the pitch angle of CAU again.In the present embodiment, because of the wide of CAU is 350mm, during according to P1=P2 ± 6mm, the pitch angle is 1 ° and measures P1 and P2, and is converted into the pitch angle.If degree of tilt in 3 °, is then installed correct.

5. measure the deflection that CAU installs

Referring to Fig. 8, by measuring the A1 method in 1., A1 in the survey sheet 8 and the value of A1 ' respectively are converted into the deflection angle of CAU again.In the present embodiment, the wide of CAU is 350mm, and during according to A1=A1 ' ± 6mm, the pitch angle is 1 ° and measures A1 and A1 ', and is converted into the pitch angle.If degree of tilt in 3 °, is then installed correct.

6. there is not the metal area distance around measuring CAU

Referring to Fig. 9, the railway norm definition, the D value among Fig. 9 is not for there being the metal area distance around the CAU.Referring to Fig. 9 right half part, because of shape right-angle triangle at 45, so Z(has surveyed) equate with S, deduct Z so D equals rail to the distance of CAU, surveyed and rail equals A1(to the distance of CAU) deduct 410/2 and S.

The utility model is made of duralumin (LC4) and aluminium section bar, superhard oxidation is adopted on the surface, has increased the hardness of tool structure to a great extent, prevents making after long-time the slip between the fixture component here the frock distortion, lose the accuracy of measurement, increased the reliability and the practicality of whole frock.Aluminium section bar makes the weight saving of whole frock, meets on-the-spot request for utilization.

Compared with prior art, the beneficial effects of the utility model are: 1, can accurately measure the various installation parameters of CAU,, avoid accident with the requirement of compliant, and the efficiency of measurement height.2, it organically combines vernier caliper and surveyor's staff, can measure at three dimensions, by changing the size of level components and height gauge assembly, just can measure the size and the position of various device, so it has also reserved expanded function.
