Detailed description of the invention

For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

The housing 1 at gasifier nozzle position is respectively arranged with four corresponding and symmetrical housing burner adapters with internals 2 5 and four internals burner interfaces 6, and hoop intersection in 90 ° is divided into two-way, is vertically placed in ten meters of dells 3 Carry out docking to measure.The measurement apparatus that the gasification furnace adapter position housing that embodiment 1,2 uses docks with internals As shown in figs 1-9, it includes theodolite assembly and adjustable backlight number of degrees device 22, described theodolite assembly bag Include swashing of lateral displacement device 16, the theodolite 17 of band standard network 26 and band laser beam emitting device camera lens 18 Light emitting devices 19.Described theodolite assembly is fixed on spider 15.Laser beam emitting device camera lens 18 sets On the collimation axis of theodolite 17.Laser beam emitting device 19 is provided with laser beam emitting device switch 27, laser Display lamp 28, laser output interface 29 and power interface 30.Laser beam emitting device camera lens 18 is provided with laser Input interface 31, set screw 32.Theodolite 17 includes that one end connects the support bar 24 of fixing device, The other end of strut 24 passes through extension rod 25 connection standard network 26, and fixing device is that V-type inhales ferrum 23.

Embodiment 1

The measuring method that a kind of gasification furnace adapter position housing docks with internals:

Step 1: after theodolite 17 and laser beam emitting device 19 connect, on distance 170 meters of left sides of theodolite A target 34 (Fig. 8) is arranged on right metope.Adjust two angles (orientation and height) of theodolite 17 Adjustable screw, makes the center of theodolite 17 collimation axis fall in target 34 in the heart.After switching on power, beat Drive laser beam emitting device switch 27.Adjust the objective focal length of theodolite 17, make the laser spots that sends clear and chi Very little minimum, checks that laser spots falls in the orientation of target 34.Inclined according to laser spots relative target target 34 center From orientation, adjust the set screw 32 on laser beam emitting device camera lens 18, until laser spots falls at target 34 In in the heart.Now, the laser beam that laser beam emitting device 19 sends is coaxial with theodolite 17 collimation axis.

Step 2: place instrument: after an adjustment is respectively placed in the outside of two adjacent housing burner adapters 5 Theodolite 17, by laser output lead by the camera lens 18 of laser beam emitting device 19 and laser beam emitting device even Being connected together, laser beam emitting device 19 switches on power.As shown in Figure 1, 2, two theodolites 17 are put respectively Put to take at 45 ° of housing burners and (left, down, right, the housing burner adapter 5 of upper end in Fig. 2 are determined respectively Justice is 45 ° of housing burner adapters, 135 ° of adapters of housing burner, 225 ° of adapters of housing burner, 315 ° of housings Burner is taken over) and outside 135 ° of housing burners take over, below theodolite 17, it is furnished with horizontal mobile device 16, The lower section of horizontal mobile device 16 connects spider 15.

Step 3: set up two laser datum straight lines:

Point on the basis of the central point of two corresponding housing burner adapters 5 respectively, by theodolite 17 Angular adjustment, the moving left and right and the lifting of spider 15 of horizontal mobile device 16, open laser beam emitting device Switch 27, sets up two laser datum straight lines, the i.e. first laser datum straight line 20 and the second laser datum straight line 21:

Step 4: the deviation at the center of two internals burner interfaces 5 of measurement homonymy:

Two adjustable backlight reading devices 22 are individually positioned in the homonymy of two theodolites 17, use V-type magnetic Ferrum 23 fixedly adjustable formula backlight reading device 22, makes two standard grids 26 lay respectively at 45 ° of internals burners After interface center 11 and 135 ° of internals burner interface center 13 cross hairs, adjust support bar 24 and prolong Stock 25, make the center of two standard grids 26 respectively with 45 ° of internals burner interface centers 11 and 135 ° The cross point of internals burner interface center 12 cross hairs overlaps.Adjust the objective focal length of theodolite, make at mark Laser spots on quasi-grid 26 is clear and size is minimum.Check that laser spots falls in the azimuth deviation of standard grid 26, 45 ° of internals burner interface centers 11 of surveying record connect relative to 20,135 ° of internals burners of the first reference line Mouth center 12 is relative to the deviation of the second reference line 21;

Step 5: the deviation at two internals burner interface centers on rear side of measurement:

Two adjustable backlight reading devices 22 are individually positioned in the opposite side of two theodolites 17 again, use V Type Magnet 23 fixedly adjustable formula backlight reading device 22, makes two standard grids 26 lay respectively at 225 ° of internals After burner interface center 13 and 315 ° of internals burner interface center 14 cross hairs, adjust support bar 24 With extension rod 25, make the center of two standard grids 26 respectively with 225 ° of internals burner interface centers 12,315 The cross point of ° internals burner interface center 14 cross hairs overlaps.Adjust the objective focal length of theodolite, make Laser spots on standard grid 26 is clear and size is minimum.Check that laser spots falls inclined in the orientation of standard grid 26 Difference, 225 ° of internals burner interface centers 13 of surveying record are burnt relative to 20,315 ° of internals of the first reference line Mouth interface center 14 is relative to the deviation (as shown in figures 10-13) of the second reference line 21;

Step 6: deviation processing:

If four internals burner interface 6 center the most respective housing burner adapter 5 center reference straight line the first bases The deviation of line of collimation 20 and the second reference line 21 all meets technology requirement, then internals are fixed in spot welding, measure knot Bundle;Otherwise, at four internals burner interface 6 center the most respective housing burner adapter 5 center reference straight lines In the deviation of the first reference line 20 and the second reference line 21, as long as having in an internals burner interface 6 Heart deviation requires it is necessary to according to the direction of deviation adjustment internals and size more than technology.Again according to step 3 and The operational measure deviation of step 4, until four internals burner interface 6 center the most respective housing burner adapters The deviation of 5 center reference straight line the first reference lines 20 and the second reference line 21 meets technology requirement, spot welding Fixing internals, measurement terminates.

Embodiment 2

The present embodiment is with the difference of embodiment 1, and the present embodiment is that two internals first measuring rear side are burnt The deviation at mouth interface center, then measure the deviation at two internals burner interface centers of homonymy, will embodiment 1 In step 4) and step 5) order exchange.
