Abstract

The utility model relates to a vertical measuring point frame. The frame is characterized in that: the frame consists of a vertical point measuring bar, a vertical point measuring bar reference surface, a longitudinal leveling instrument, a horizontal leveling instrument, a support board, a support adjusting screw, a magnetic prism base and a sphere prism, wherein the vertical point measuring bar and the vertical point measuring bar reference surface are perpendicular to each other and are formed into a whole; the support board is vertically fixed under the vertical point measuring bar through a support board fastening screw, and is supported by the support adjusting screw; the horizontal leveling instrument and the longitudinal leveling instrument are arranged at both sides under the vertical point measuring bar reference surface and at an angle of 90 degrees; the magnetic prism base is arranged above the vertical point measuring bar reference surface; and the sphere prism is arranged at the center of the magnetic prism base. The vertical measuring point frame has the advantages that: a measured impact point is drawn upwards vertically so as to reduce gross measurement error and uncertainty caused by nonlevel placement of a workpiece; moreover, point position pointing accuracy is less than 0.1mm after the measured impact point is drawn upwards vertically.

Description

A kind of vertical survey point frame

Technical field

The utility model relates to a kind of vertical survey point frame, and the measurement of angle between range observation between the point that is used for membrane type spiral water-cooling wall examination assembly unit and point and point and the line of putting formation belongs to the length metering technical field of measurement and test.

Background technology

Outer 0701 membrane type spiral water-cooling wall is the product that my company is given in the subpackage of French Alstom, foreign side to the assembly unit requirement of spiral water-cooling wall and measuring method clearly regulation must measure and proofread and correct with transit, measure the length that two of nearly 60m dash point, only allow ± tolerance of 3mm, existing measurement frock can't meet the demands, and measurement point is dashing a little on pipe, band magnetic prism pedestal can not be put the placement of extending vertically upward with measured dashing, so will extend vertically upward towards point is main points and the key of measuring, otherwise will bring very big sum of errors uncertainty.

Summary of the invention

The purpose of this utility model provides the vertical survey point frame of a kind of measuring error less than 3mm.

For realizing above purpose, the technical solution of the utility model provides a kind of vertical survey point frame, it is characterized in that, by the vertical point mark post, vertical point mark post reference field, longitudinal level, transversal bubble, supporting plate, the bracket adjustment screw, band magnetic prism pedestal, prismosphere is formed, vertical point mark post and vertical point mark post reference field are mutually perpendicular to one, supporting plate is vertically fixed on the below of vertical point mark post by the supporting plate holding screw, and by the support of bracket adjustment screw, the below that transversal bubble and longitudinal level are located at vertical point mark post reference field both sides at an angle of 90, band magnetic prism pedestal is located at vertical point mark post reference field top, and prismosphere is located at the center of band magnetic prism pedestal.

Described vertical point mark post reference surface center is provided with vertical point mark post reference field 3mm central campus on schedule, and the 3mm central campus is top on same center line with the vertical point mark post on schedule; Described band magnetic prism pedestal center is taper, and conical centre is the circular hole of 3mm.

Principle of the present utility model: prismosphere center, the center of band magnetic prism pedestal, the center and the top of vertical point mark post of vertical point mark post reference field are in together on the central axis, the prismosphere central point that obtains promptly is measured vertically the extending a little of point of dashing, and the precision of Ce Lianging can meet the demands like this.

The utility model has the advantages that measured dashing a little extended vertically upward, reduce that precision＜0.1mm is sighted in the measured some position that dashes after point is extended vertically upward because workpiece is put out-of-level thick measuring error and the uncertainty of bringing.

Fig. 1 is a kind of vertical survey point frame structural representation;

Fig. 2 is a vertical point mark post reference field structural representation;

Fig. 3 is the top calibrate bar of a 3mm structural representation.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment

As shown in Figure 1, 2, be a kind of vertical survey point frame structural representation, described a kind of vertical survey point frame is made up of vertical point mark post 1, vertical point mark post reference field 2, longitudinal level 3, transversal bubble 4, supporting plate 5, bracket adjustment screw 7, band magnetic prism pedestal 8, prismosphere 9, the top calibrate bar 11 of 3mm.

Vertical point mark post 1 and vertical point mark post reference field 2 are mutually perpendicular to one, described vertical point mark post reference field 2 centers are provided with vertical point mark post reference field 3mm central campus on schedule 10, the 3mm central campus is 10 top on same center line with vertical point mark post 1 on schedule, supporting plate 5 is vertically fixed on the below of vertical point mark post 1 by supporting plate holding screw 6, and by 7 supports of 3 bracket adjustment screws, the below that transversal bubble 4 and longitudinal level 3 are located at vertical point mark post reference field 2 both sides at an angle of 90, band magnetic prism pedestal 8 is installed in vertical point mark post reference field 2 tops, prismosphere 9 is placed on the center of band magnetic prism pedestal 8, described band magnetic prism pedestal 8 centers are taper, and conical centre is the 3mm circular hole.

During measurement, as shown in Figure 3, pass the circular hole at band magnetic prism pedestal 8 centers with the top calibrate bar 11 of 3mm, aligned perpendicular point mark post reference field 3mm central campus on schedule 10, securely coincide together with the baseplane of magnetic prism pedestal 8 and the reference field of vertical point mark post 1 this moment, places prismosphere 9 then on band magnetic prism pedestal 8; Measured the dashing a little of the top aligning of vertical point mark post 1, regulate the 1 piece bracket adjustment screw 7 parallel with longitudinal level 3, make longitudinal level 3 zero setting, top and this root bracket adjustment screw 7 of vertical point mark post 1 has formed two fulcrums at this moment; Regulate the 2 piece bracket adjustment screws 7 parallel with transversal bubble 4, regulate wherein 1 earlier, make transversal bubble 4 same zero setting, at this moment 3 fulcrums have been formed, gently revolve 1 bracket adjustment screw 7 contact bottom in addition then downwards, this moment, the central point of prismosphere promptly was measured vertically the extending a little of point of dashing, and recorded a position that dashes point earlier, record the position that another dashes point then after the same method, can calculate two distances of dashing point by Survey Software.In like manner, measure the 3rd measured towards point, can obtain the angle that needs.
