It measures.
Adjustable support 1 includes using for the horizontal location plate 11 of fixed suspension prism 2 and in 11 side of horizontal location plate
In the adjusting rod 12 of support level positioning plate 11, wherein, prism 2 is lifted on the middle position of horizontal location plate 11, adjusting rod 12
The height of horizontal location plate 11 can be adjusted, so that horizontal location plate 11 is horizontal, when in use, passes through adjusting rod
12 adjusting horizontal location plates 11 make its horizontal, then measure absolute altitude.
Wherein, adjusting rod 12 is set as three, and three are in equilateral triangle, is uniformly arranged on close to 2 side of prism
Surrounding, so as to relatively stable support level positioning plate 11, meanwhile, horizontal location plate is adjusted using adjusting rod 12
11 it is horizontal when, due to only using three adjusting rods 12, during adjusting, be relatively easy to leveling, meanwhile, horizontal location plate 11 is more steady
It is fixed.
Further, adjusting rod 12 can be adjusted, i.e., can be carried out in length of the horizontal location plate 11 close to 2 side of prism
Adjust, offer adjusting screw hole 111 on horizontal location plate 11, adjusting rod 12 pass through adjusting screw hole 111 and with adjusting screw hole 111
It is threadedly coupled, so as to pass through rotation adjusting lever 12, thus it is possible to vary adjusting rod 12 passes through in the position of 11 lower section of horizontal location plate
Change the length of three adjusting rods 12, so as to which level be adjusted to horizontal location plate 11.
In order to facilitate use, fixed in the upper end of adjusting rod 12 in end of the horizontal location plate 11 far from 2 side of prism
Rotation hand knob 121 is provided with, so as to facilitate rotation adjusting lever 12.
It is more preferred, level(l)ing bubble 13 is fixedly installed on horizontal location plate 11, and level(l)ing bubble 13 is provided with two
It is a, it is mutually perpendicular between two level(l)ing bubbles 13, a level(l)ing bubble 13 is parallel with two 12 line directions of adjusting rod, thus
When adjusting horizontal, when two level(l)ing bubbles 13 all show level, then horizontal location plate 11 is in level, preferably, level(l)ing bubble
13 be preferably long level(l)ing bubble 13, when being adjusted, can preferably show level so that it is more accurate to measure.
More, in the interim absolute altitude datum mark 112 that has been fixedly arranged at the upper side of horizontal location plate 11, and interim absolute altitude benchmark
Point 112 is the spherical shape in one end far from horizontal location plate 11 in the upper end of horizontal location plate 11, and when being monitored, Sopwith staff is put
It puts and measures absolute altitude on interim absolute altitude datum mark 112, by the interim absolute altitude datum mark 112 of setting, with Sopwith staff lower extreme point
Contact, so as to reduce the operating error caused by the injustice of Sopwith staff end.
In construction, the possible out-of-flatness in ground, in order to reduce influence of the ground out-of-flatness to measurement work, adjusting rod
12 lower end setting is in tip-shape, thus so that 12 points of supports of adjusting rod on the ground, face with preferably avoiding out-of-flatness
The influence of horizontal location plate 11.
Further, adjusting rod 12 is more than the length of prism 2 in the length that level is determined below positioning plate, so as to rib
Mirror 2 is protected, and is reduced it and is collided.
Embodiment two：
The present embodiment and one structure of embodiment the difference lies in：As shown in Fig. 2, horizontally outward extend on horizontal location plate 11
There are three extension bar 113, adjusting rod 12 is arranged on the one end of 113 end of extension bar i.e. far from horizontal location plate 11, passes through for molding
The extension bar 113 of setting can reduce the area of horizontal location plate 11, so that entire measuring device quality is lighter, right
When different floors is detected, carry more convenient.
Embodiment three：
The present embodiment and one structure of embodiment the difference lies in：As shown in figure 3, the regulative mode of adjusting rod 12.
Adjusting rod 12 includes the regulating sleeve 122 being fixed on horizontal location plate 11 and is plugged in regulating sleeve 122
Supporting rod 123, wherein, hook knob 124 is threaded on the side wall of regulating sleeve 122, hook knob 124 can pass through
122 side wall of regulating sleeve is connected on supporting rod 123, so as to which supporting rod 123 be fixed.
When in use, supporting rod 123 is slided in regulating sleeve 122, so as to change the entire length of adjusting rod 12,
So as to fulfill the horizontal purpose for adjusting horizontal location plate 11, need what is illustrated, the fixed form of regulating sleeve 122 can be weldering
It connects or is threadedly coupled and fix.
Example IV：
As shown in figure 4, it is a kind of using the vertical transfer device of absolute altitude measurement absolute altitude method, measure absolute altitude the specific steps are：
A, total powerstation horizontal line of sight absolute altitude is determined
Total powerstation 3 is erected on lower floor's floor, and is directed at the measured hole 41 that upper strata floor 4 opens up, it is true by using Sopwith staff 31
Determine the horizontal absolute altitude S1 of total powerstation.
B, prism is set up
Adjustable support 1 is placed on upper strata floor 4 and is located at measured hole 41 so that the infrared ray that total powerstation is sent out can
It is radiated on prism 2, by adjusting rod 12, by 11 leveling of horizontal location plate, meanwhile, it determines on prism 2 to horizontal location plate 11
The distance between the interim absolute altitude datum mark 112 in surface S2.
C, total powerstation sight absolute altitude is measured to prism absolute altitude
Total powerstation 3 is directed at camera lens and carries out reading, total powerstation is obtained and throws survey reading S3（I.e. between total powerstation center and camera lens away from
From）, calculate：The horizontal absolute altitude S1+ total powerstations of horizontal location plate upper surface absolute altitude H plates=total powerstation, which are thrown, surveys reading S3+ S2.
D, using spirit level by absolute altitude pilot measurement to required position
Levelling rod 32 is placed on interim 112 upper end of absolute altitude datum mark, and passes through spirit level 33 and reading is carried out to levelling rod 32, is obtained
To 33 backsight of spirit level, calculate：33 horizontal absolute altitude H water of spirit level=H plates+spirit level backsight, then by levelling rod
32 stand on tested point, and pass through 33 reading of spirit level, obtain 33 forward reading of spirit level, then absolute altitude H=H water-water of tested point
Quasi- instrument forward reading.
This application method by the adjustable support 1 of setting, is placed it at the measured hole 41 on upper strata floor 4, can
It is more convenient to operating on it, when replace floor carry out absolute altitude when, measure it is simple, easy to carry.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, people in the art
Member can as needed make the present embodiment the modification of no creative contribution after this specification is read, but as long as at this
It is all protected in the right of invention by Patent Law.
