Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Refer to Fig. 1-3, the mounting structure of shield range restraint measurement forced centering bracket:
Bracket 1 includes setting up and down two otic placode 1-1, is provided with installing hole 1-1-1, two otic placode shapes on two otic placodes
Becoming angle, the medial surface of two otic placodes forms locating surface and lower locating surface respectively, is provided with connecting plate 1-2 between two otic placodes,
Connecting plate connects near the position of upper end gripper shoe 1-3 horizontally outward extended, and the upper surface of gripper shoe forms measuring instrument peace
Assembling platform, the position near middle part is welded with the shank of bolt 1-4 for fixation measuring instrument on the supporting plate, in connecting plate and support
Connecting between plate and have tilt prop 1-5, connecting plate, gripper shoe and tilt prop form triangle joint structure.
Two otic placodes pass through two locating surfaces snaps respectively, in the two panels section of jurisdiction building block 2 that existing tunnel is circumferentially adjacent
Organize on the two ends locating surface of prefabricated hoop bolt connecting hole, the angle of two side-locating faces formation of i.e. two otic placodes and two side-locating faces
Between distance and shield tunnel in the location, two ends of prefabricated hoop bolt connecting hole in circumferentially adjacent two panels section of jurisdiction building block
The distance between angle and two ends locating surface between face is the most consistent.And above-mentioned two otic placodes are by through this group prefabricated hoop bolt
The hoop segment bolt 3 of the installing hole on connecting hole and two otic placodes is fixed in described two panels section of jurisdiction building block, the prefabricated ring of this group
It is arranged in the middle part of tunnel to bolt connecting hole or position that middle part is on the lower side.
