Figure is as shown in figure 1, the fixed block 1 including fixing end, gauge head body 2, band elastic piece 3, radial direction stopper slot 4, the He of fixed screw 5
Annular array gauge head 6.The maximum radius of curvature up to shaft in wall of the radius of curvature of above-mentioned band elastic piece 3, can effectively keep away
Exempt from due to the smaller caused screens phenomenon of roller radius.
Above-mentioned band elastic piece 3 has a fixing end for being linked to gauge head body 2 and a free end.The gauge head pipe
The diameter of body 2 is less than gas storage well inner diameter, and the front and rear of the gauge head body 2 is provided with the fixation of fixed strip flexure strip
Block 1, leaves 2 screwed holes on each fixed block, the screwed hole fixes the fixing end of strip flexure strip 3, gauge head by fixed screw 5
The middle part of body 2 is provided with the stopper slot 4 of the free end of limitation band elastic piece 3, and installs pipe clamp additional at the middle part of stopper slot 4, limits
Position groove 4 makes the free end of radian band elastic piece 3 to be moved along the axial direction of gauge head body 2.
The band elastic piece 3 is forward and backward to placing a pair along the axial direction of gauge head body 2, and in gauge head body 2
Stagger certain angle in the radial direction, forms angled former and later two strong points of tool.
The band elastic piece 3 along the paired uniform arrangement of the radial direction of gauge head body 2, its quantity be 3 pairs and more than,
Be conducive to increase uprighting force and annular array gauge head 6 is maintained at pit shaft middle position and coaxially parallel with pit shaft.
The thickness of the band elastic piece 3 be less than width, can reach flexure strip it is in axial direction pliable preferably, Yi Jiyan
The preferable purpose of radial direction intensity.
The band elastic piece 3 is made using the material with good draftability and certain rigid, with good
Tensile property, contributes to flexure strip in axial direction to move, and is easy to that gauge head is agile in well to be moved up and down, meanwhile, radially side
Larger uprighting force is preferably provided to intensity.
Because gas storage well bore internal diameter is not of uniform size, using single bow structure, its Dan Gong is arranged on solid the band elastic piece
Fixed end, goes for large range of well radius variations.
After gas storage well gauge head centralizer installation, the maximum outside diameter of gas storage well gauge head centralizer is more than in gas storage well bore
Footpath, in the case where dynamic action is opened, gauge head and centralizer one are removed into gas storage well.The Dan Gong of the big radian flexure strip is come from
The pressure effect of shaft in wall, the bow height of big radian flexure strip diminishes generation elastic deformation, and free end axially extends, its reset
Power serves as uprighting force.When gauge head is moved up and down in well, run into pit shaft internal diameter and change or during etch pit, centralizer is utilized
The bow of flexure strip is high and free end it is flexible can consecutive variations adjustment effect, realize that gauge head is freely up and down moved in gas storage well.
In the application, according to the different centralizers using different size of tested pit shaft internal diameter, every group of centralizer adapts to certain
Inside diameter ranges, to ensure that centralizer telescopic extensions are matched with elastic size, reach optimal righting effect.
In sum, the gas storage well gauge head centralizer based on band elastic chip architecture of the embodiment of the present invention uses strip bullet
Property chip architecture, can be in close contact band elastic piece and shaft in wall, it is ensured that annular array gauge head is coaxially put down with gas storage well bore
OK, and be effectively prevented from the phenomenon of supporting leg roller screens at pit shaft joining place and barrel etch pit, realize in well up and down from
By movement, protection gauge head, the accuracy of detection and efficiency of annular array gauge head are improved.
Simple structure, the uprighting force of the gas storage well gauge head centralizer based on band elastic chip architecture of the embodiment of the present invention
Greatly, suitable for hole diameter scope it is big, be unlikely to deform, it is to avoid complicated machinery leg structure, convenient disassembly reduces maintenance cost.
