Abstract
The utility model discloses a measuring device for space plane flatness. A plurality of measuring points are uniformly arranged on the end face of a segment to be measured; a total station with the autocollimation function is arranged on a construction platform at one side of the segment to be measured; and the total station is connected with a computer through wires. The utility model has the advantages that the position information of the measuring points is collected by the total station, the information is processed by the computer to obtain the end face flatness of the segment, the measuring data of the flatness of the segment can be timely obtained, the structure is concise, the cost is low, the flatness can be measured by the construction party without entrusting the other party or being limited by the other party, the production cost is greatly reduced, the measuring process can be repeated, and the accuracy of the measuring result is improved.
Description
Technical field
The utility model relates to large-diameter shield constructing device field, specifically is a kind of at the negative measurement mechanism that encircles measurement space flatness in the assembly unit of the first ring of large-diameter shield construction.
Background technology
In the negative ring of the first ring assembly unit engineering, because diameter is bigger, the assembly unit piece of every endless tube sheet is more relatively in large-diameter shield construction, so the flatness of reference surface and wedge shape measurement amount just seem very crucial.In large-diameter shield construction in the past, most of professional surveying and mapping company and the specialized equipment thereof of relying on of the space plane roughness measurement work of negative ring assembly unit engineering, the shortcoming of this pattern has:
(1), can not in time obtain measurement data, cause construction speed to lag behind;
(2), be unfavorable for the raising of unit in charge of construction's operating technique ability making construction party under one's control at technical elements.
(3), from the cost control aspect, rely on third party unit, from measuring data processing, all need pay high cost, strengthened the cost expenditure.
(4), unit in charge of construction can't check the construction data that mapping company provides, and this measurement data is difficult to further computational analysis application.
(5), its specialized equipment price is very high.
Summary of the invention
The utility model provides a kind of measurement mechanism of space plane flatness, it can solve the deficiency that exists in the known technology, employing has the total powerstation of sighting function automatically and comes measurement data, and data transfer is analyzed in computing machine, finally obtains the measurement result of space plane flatness.
The utility model for achieving the above object, be achieved through the following technical solutions: the measurement mechanism of space plane flatness, on section of jurisdiction end face to be measured, some measurement points are set evenly, setting has the total powerstation of sighting function automatically on the operation platform of section of jurisdiction to be measured one side, and total powerstation is connected with computing machine by lead.
On operation platform top first total powerstation is set, the operation platform bottom is provided with second total powerstation, and first total powerstation is corresponding with identical ring plate position with second total powerstation.
Advantage of the present utility model is: adopt total powerstation to gather the positional information of measurement point, and utilize computing machine that this information is handled the flatness that obtains the section of jurisdiction end face, can in time obtain section of jurisdiction roughness measurement data; Simple for structure, cost is low, and construction party self just can be measured flatness, need not the through committing others or is subject to other people, greatly reduces production cost; Measuring process can be carried out repeatedly, improves the degree of accuracy of measurement result etc.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail for the contrast accompanying drawing:
The measurement mechanism of space plane flatness described in the utility model, its agent structure is included in some measurement points 4 evenly is set on 3 end faces of section of jurisdiction to be measured, the quantity of described measurement point 4 requires to set according to measuring accuracy, and measuring accuracy requires high more, and the measurement point of required setting is many more.Setting has the total powerstation of sighting function automatically on the operation platform 6 of section of jurisdiction to be measured 3 one sides, utilizes total powerstation that each measurement point 4 is taken a picture, thereby obtains the positional information of each measurement point.Described total powerstation is connected with computing machine 7 by lead, positional information after total powerstation will be measured is input in the computing machine 7, adopt software program that information is handled by computing machine 7, set up unified coordinate system, the positional information of each measurement point 4 is unified in this coordinate system, computing machine 7 adopts AUTOCAD software that this information is handled, and finally obtains with the flatness of measuring section of jurisdiction 3 end faces.Number in the figure 8 is a construction tunnel.
The utility model is further characterized in that: when the measurement point 4 on 3 end faces of section of jurisdiction to be measured lays respectively at operation platform about in the of 6 during both sides, can be provided with first total powerstation 2 this moment on operation platform 6 tops, in operation platform 6 bottoms second total powerstation 1 is set, and first total powerstation 2 is corresponding with identical ring plate 5 positions with second total powerstation 1.Two total powerstations are measured the measurement point 4 on 3 end faces of section of jurisdiction to be measured simultaneously then, and data are imported into respectively in the computing machine 7 calculate, thereby draw the flatness of section of jurisdiction to be measured 3 end faces.
Claims (2)
1. the measurement mechanism of space plane flatness, it is characterized in that: on the end face of section of jurisdiction to be measured (3), some measurement points (4) are set evenly, go up setting at the operation platform (6) of section of jurisdiction to be measured (3) one sides and have the total powerstation of sighting function automatically, total powerstation is connected with computing machine (7) by lead.
2. the measurement mechanism of space plane flatness according to claim 1, it is characterized in that: first total powerstation (2) is set on operation platform (6) top, operation platform (6) bottom is provided with second total powerstation (1), and first total powerstation (2) is corresponding with identical ring plate (5) position with second total powerstation (1).
