Technical field
The utility model relates to a kind of right angle Position Scale, particularly a kind of right angle Position Scale that the shield door step plate is installed.
Background technology
The installation of screen door in rail transit step plate is the most important thing that whole shield door is installed, and installation dimension is not in place, directly influences the quality that whole shield door is installed.Step plate is installed the spacing dimension (1403 that not only will consider step plate and orbit centre
0 + 10Mm), also to consider the relative elevation size (1050 of step plate apart from the tread height
-10 0Mm), the levelness of step plate (≤2mm) and the spacing (12 ± 0.4mm) between two jigsaw of step plate.As finishing this work, use spirit-leveling instrument to construct by classic method, increase labour intensity and do not say, also to pay considerable manpower.
The utility model content
From accelerating the consideration of installation progress and reduction installation difficulty, the special right angle Position Scale of having done.
For achieving the above object, the technical solution of the utility model is as follows:
The right angle Position Scale comprises scale vertical beam (1), it is characterized in that, also comprises scale crossbeam (3), support end (4), and an end of described scale crossbeam (3) and scale vertical beam (1) link together, and the other end and support end (4) link together.
The right angle Position Scale is characterized in that, comprises reinforcement block (2), and reinforcement block (2) is connected the junction of scale vertical beam (1) and scale crossbeam (3) and the junction of support end (4) and scale crossbeam (3).
One end of scale vertical beam (1) and scale crossbeam (3) welds together.
The other end of scale crossbeam (3) and support end (4) weld together.
One end, the scale crossbeam (3) of reinforcement block (2) and scale vertical beam (1) welds together and the other end of scale vertical beam (1), and support end (4) welds together.
Beneficial effect:
In the installation process, behind the employing right angle Position Scale, improve the operating efficiency height, reduced difficulty of construction.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 to Fig. 5 is the structural representation that step plate is installed with classic method;
Fig. 6 to Fig. 8 is the structural representation that step plate is installed with the utility model;
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, the right angle Position Scale comprises scale vertical beam 1, it is characterized in that, also comprises scale crossbeam 3, support end 4, and an end and the scale vertical beam 1 of described scale crossbeam 3 link together, and the other end and support end 4 link together.
The right angle Position Scale is characterized in that, comprises reinforcement block 2, and reinforcement block 2 is connected the junction of scale vertical beam 1 and scale crossbeam 3 and the junction of support end 4 and scale crossbeam 3.
One end of scale vertical beam 1 and scale crossbeam 3 welds together.
The other end of scale crossbeam 3 and support end 4 weld together.
One end, the scale crossbeam 3 of reinforcement block 2 and scale vertical beam 1 welds together and the other end of scale vertical beam 1, and support end 4 welds together.
As shown in Figure 2, step plate 6 is installed the spacing dimension 10 (1403 that not only will consider step plate 6 and orbit centre
0 + 10Mm), also to consider the relative elevation size 9 (1050 of step plate 6 apart from the height at track 8 tops
-10 0Mm), the levelness of step plate 6 (≤2mm) and the spacing (12 ± 0.4mm) between 6 two jigsaw of step plate.
The classic method that step plate is installed is:
As shown in Figure 3, set up a spirit-leveling instrument 16 on platform 5,5m Sopwith staff 11 rests on the track 8, reads the scale of Sopwith staff 11 from spirit-leveling instrument 16.Then 5m Sopwith staff 11 is moved on to step plate 6 positions, read Sopwith staff 11 scales, as shown in Figure 4.Scale 1 is deducted scale 2, obtain step plate 6 and track 8 relative elevation sizes.If do not reach installation provision size 1050mm, regulate step plate 6 height successively, remeasure the absolute altitude of step plate 6 again, the data of reading up to spirit-leveling instrument 16 satisfy installation requirement.
When carrying out above-mentioned work, also need constantly to adjust step plate 6 and the spacing dimension of track 8, the levelness of step plate 6 and the spacing between 6 two jigsaw of step plate.Adjust the spacing dimension of step plate 6 and track 8, need use plumb bob 13, ruler 12, as shown in Figure 5.The levelness level measurement of step plate 6, the spacing between 6 two jigsaw of step plate is measured with ruler 12.
The spacing dimension of step plate 6 and orbit centre 7, step plate 6 are apart from relative elevation size, the levelness of step plate 6 and the spacing between 6 two jigsaw of step plate of the height on track 8 tops, these four sizes all are relevant interlocks, step plate 6 is as long as there is adjustment at a place, and its excess-three place size all can change.Therefore, step plate 6 of every installation, all will to this everywhere size carry out checking measurements, deviation does not take place to guarantee installation accuracy.The installation difficulty of conventional mounting method is big, and efficient is low, and installation progress is slow, can't satisfy the requirement of construction speed.
By the installation work of M8 line shield door facts have proved that right angle Position Scale 14 has improved work efficiency, reduced the installation difficulty of step plate 6, have suitable practicality and economy.Use this right angle Position Scale again in the installation work of M6 line shield door.
As shown in Figure 6, use right angle Position Scale 14, only need the one end is rested on the platform 5, the other end rests on the track 8, and the block of right angle Position Scale 14 is close to track 8.Put level meter 15 on right angle Position Scale 14 crossbeams, crossbeam is adjusted to level.When step plate 6 is installed, as shown in Figure 7, only need to measure the distance of step plate 6 and right angle Position Scale 14 crossbeams with ruler, whether the absolute altitude that can measure step plate 6 satisfies installation requirement (because of the tread distance of Position Scale crossbeam lower end, right angle and track is a fixed value), need not to read the Sopwith staff scale repeatedly with spirit-leveling instrument.
The spacing dimension of step plate and orbit centre also can measure with ruler, as shown in Figure 8.
After using the right angle Position Scale, when step plate is installed, no longer need spirit-leveling instrument, Sopwith staff and plumb bob to measure the shift position repeatedly, can measure all installation dimensions with ruler.Therefore, in the installation process, behind the employing right angle Position Scale, improve the operating efficiency height, reduced difficulty of construction.
