Abstract
A group pairing detection method for large-scale memorial archway equipment comprises the following steps: firstly, detecting upright column centering; adjusting the cushion blocks of the upper and lower upright posts; adjusting the upper and lower arched girders; fourthly, the laser tracker is used for retesting the overall installation precision of the memorial archway. The invention adopts the laser tracker to respectively detect the centering of the post of the large-scale memorial archway equipment group, adjust the cushion blocks of the upper post and the lower post and adjust the upper arched beam and the lower arched beam, thereby not only ensuring the detection speed, but also ensuring the installation precision and the measurement precision.
Description
Technical field:
The present invention relates to a kind of assemble method of heavy mechanical equipment, particularly a kind of group of large-scale memorial archway kind equipment is to detection method.
Background technology:
In order to satisfy needs of economic development, device design is increasing with the size and the tonnage that produce, and an equipment can reach several kilotons sometimes.Therefore, equipment can't whole be supplied, and can only be assembled into integral body again behind the segmentation entering scene.And assembled on site is actually the further part of device fabrication, and assembly precision all is the installation and measuring that requires according to device fabrication manufacturer.The frequent form and position tolerance method of hanging steel wire messenger wire bob+steel ruler measurement checkout facility that adopts is measured inspection form and position tolerance method with extension steel wire messenger wire bob+micrometer inside caliper in the assembling.The former assembles quick and easy, but precision is lower; Latter's assembly precision is higher, but artificial precision influence factor is too many and efficient is lower in the operation.
Summary of the invention:
The object of the invention just is to overcome the deficiency that exists in the above-mentioned prior art; And the group that a kind of large-scale memorial archway kind equipment is provided is to detection method; The group that this method employing laser tracker carries out main equipment is to measuring; Both can simply measure installation accuracy fast, and can guarantee that again measuring accuracy was accurate.
As above design, technical scheme of the present invention is: a kind of group of large-scale memorial archway kind equipment is characterized in that detection method: comprising: 1. column centering is detected: behind the column hoisted in position, with two columns of laser tracker leveling, adjustment column center position; After the column center mixes up; Measure two column two-end-points, central point and column edge symmetrical 2 coordinate arbitrarily respectively with laser tracker and spherical prism; Go out the planimetric position of two columns then with the coordinate fitting of these points; Calculate the spacing and the depth of parallelism of column thus, utilize the distance between the two column two-end-point diagonal line to adjust again at last, qualified until adjustment; 2. upper and lower column cushion block adjustment: install on column the qualified back of column adjustment, the lower pillar stand cushion block; Measure the coordinate that column two-end-point coordinate and cushion block install its outer end points of back respectively with laser tracker and spherical prism then, calculate with this and adjust the column cushion block; 3. upper and lower arched girder adjustment: after the adjustment of column cushion block is qualified upper and lower arched girder hoisted in position is formed whole memorial archway; With laser tracker and spherical prism the flatness and the physical dimension of whole memorial archway are adjusted; Measure 8 point coordinate of upper and lower arched girder inner arc then respectively; With this optimality criterion circle that simulates upper and lower arched girder inner arc, draw the arched girder radius, calculate the arched girder cylindricity; 4. use laser tracker the integral installation precision of memorial archway is carried out repetition measurement.
The present invention adopt laser tracker respectively to large-scale memorial archway kind equipment group to after column centering detect, upper and lower column cushion block is adjusted, upper and lower arched girder is adjusted, and both can guarantee detection speed, can guarantee installation accuracy and measuring accuracy again.
Description of drawings:
Fig. 1 is a 660MN extruding/drop press column adjustment synoptic diagram;
Fig. 2 is a 660MN extruding/drop press column cushion block adjustment synoptic diagram;
Fig. 3 is a 660MN extruding/drop press arched girder adjustment synoptic diagram up and down.
Embodiment:
Utilize the present invention to the heavily about 1500t of the monolithic memorial archway of 660MN extruding/drop press, this equipment divides ten sections working-yard groups of supplying right, adopts the present invention to organizing measuring.Concrete grammar is following:
1) column centering is detected:
Behind the column hoisted in position, with two columns of laser tracker leveling, and then with laser tracker adjustment column center position.After the column center mixes up; Measure and A, B, C, D point coordinate respectively at 1,2,3,4,5,6 with laser tracker 1 and spherical prism 2, see Fig. 1: 660MN extruding/drop press column adjustment synoptic diagram goes out the planimetric position of two columns with the coordinate fitting of each point; Calculate the spacing and the depth of parallelism of column thus; The coordinate Calculation of ordering with A--D the distance between diagonal line AC and BD, adjusts according to this numerical value, and is qualified until adjustment.
2) go up the adjustment of lower pillar stand cushion block:
Install the lower pillar stand cushion block after the column adjustment is qualified; After last lower pillar stand cushion block installs; Measure the coordinate of 7--14 respectively with laser tracker and spherical prism, see Fig. 2: 660MN extruding/drop press column cushion block adjustment synoptic diagram, calculate adjustment column cushion block with this.
3) arched girder adjustment up and down:
To arched girder hoisted in position up and down after the adjustment of column cushion block is qualified, whole memorial archway upper surface is measured, memorial archway top surface plane degree is adjusted according to measuring numerical value with laser tracker and spherical prism.Adjustment is measured to the physical dimension of whole memorial archway in the qualified back of flatness adjustment; Measure the 15--30 point coordinate, simulate the optimality criterion circle of arched girder inner arc up and down with this, see Fig. 3: 660MN extruding/drop press is arched girder adjustment synoptic diagram up and down; Draw the arched girder radius, calculate the arched girder cylindricity.
4) memorial archway repetition measurement:
After the assembling of 660MN extruding/drop press memorial archway, use laser tracker the integral installation precision of memorial archway is carried out repetition measurement, guarantee that the integral installation precision meets installation requirement.
