As shown in Figure 6 and Figure 7, in the present embodiment, the principle of work of the utility model pipeline detector centering device is as follows:
When internal diameter of the pipeline increases, support wheel 10 does not touch inner-walls of duct, spring 3009 shrinks, traction moving arm carrier seat 3005 slides along slide rail 50 to the direction away from surveying instrument 60, thus drive the fixed arm of sway brace 20 and lever arm mutually to draw in, support wheel 10 opens to inner-walls of duct direction, until support wheel props up inner-walls of duct, or spring 3009 draws the outer end (now internal diameter of the pipeline change is excessive, the larger sized train unit of replaceable use) of moving arm carrier seat 3005 to slide rail;
When internal diameter of the pipeline reduces, inner-walls of duct gives the pressure that support wheel 10 shrinks to axle center, support wheel 10 draws in axle center, fixed arm and the lever arm of sway brace 20 open mutually, moving arm carrier seat 3005 is driven to slide along slide rail 50 to the direction of surveying instrument 60, until the thrust-balancing that the negative drawing power that gives of spring 3009 and lever arm bring.
In addition, varying in size according to internal diameter of the pipeline, can select the different connecting holes on the second end of fixed arm support 3004 and moving arm carrier.When Figure 6 shows that the connecting hole selected farthest away from axle center, spring 3009 shrink traction support wheel 10 be flared to expanded diameter maximum time structure.When Figure 7 shows that the connecting hole selected near axle center, spring 3009 stretching and drawing support wheel 10 collapse to expanded diameter minimum time structure.
Fig. 8 is the train cellular construction schematic diagram of the utility model pipeline detector centering device second embodiment.
As shown in Figure 8, the difference of present embodiment and the first embodiment is mainly following 2 points:
1, in the first embodiment, slide rail 50 and surveying instrument 60 are fixed on described support bracket fastened same side; And in the present embodiment, slide rail 50 and surveying instrument 60 are fixed on described support bracket fastened two relative side, described train unit also comprises a stiff end, and slide rail 50 first end is fixed on described fixed support, and the second end is fixed on described stiff end.Particularly, as shown in Figure 8, surveying instrument 60 is fixed on the right side of instrument Connection Block 3001, and slide track seat 3002 is fixed on the left of instrument Connection Block, and slide rail 50 first end is fixed on slide track seat 3002, and second segment is fixed on the stiff end in left side.This set-up mode is determined by the size of train unit, train unit in present embodiment is applicable to the pipeline that internal diameter is 90mm-125mm, insufficient space between three one slide rails is to hold surveying instrument, therefore train unit can only be arranged on the opposite side of instrument Connection Block, when the size of train unit increase to be enough to arrange surveying instrument between slide rail time, slide rail and surveying instrument should be adopted to be fixedly mounted on the setting of fixed support homonymy, thus to shorten the entire length of centering device and surveying instrument.
