11.Small standpipe 9 is solid steel tube, and intermediate casing 10 and outer side sleeve 11 are hollow steel pipe, and the small outer wall of standpipe 9 has screw thread, middle
The inwall of sleeve pipe 10 has screw thread, the two threaded engagement.The equal non-threaded of the inside and outside wall of outer side sleeve 11.Intermediate casing 10, outer side sleeve 11
Lower end surface has teeth, and brake hoop B13, brake hoop A12 upper ends have teeth.
The outer wall of intermediate casing 10 has a neck A26, and card is stretched into the hole of the screw rod on clamp screw A24 through brake hoop A12 walls
In groove A26.When clamp screw A24 is placed in neck A26 tops and tightened, brake hoop A12 and the clamping of intermediate casing 10, brake hoop
A12 upper ends teeth are engaged with the lower end surface teeth of outer side sleeve 11, cause nothing between outer side sleeve 11 and intermediate casing 10
Relative motion.
The small outer wall of standpipe 9 has a neck B27, and neck is stretched into the hole of the screw rod on clamp screw B25 through brake hoop B13 walls
In B27.When clamp screw B25 is placed in neck B27 tops and tightened, brake hoop B13 and the small clamping of standpipe 9, brake hoop B13 tops
End-side teeth is engaged with the lower end surface teeth of intermediate casing 10, without relative motion between intermediate casing 10 and small standpipe 9.
Intermediate casing 10 and angular wheel B21, locating rod 22 are connected as one, and outer side sleeve 11 is connected with triangle frame 23
It is integrated, the one end of screw rod 19 connects as one with angular wheel A20, other end insertion triangle frame 23.Screw rod 19 passes through positioning
Block 17 and it is engaged with the internal whorl of locating piece 17, locating piece 17 can be along the translation of graduated scale 18.Angular wheel A20 and angular wheel
B21 is engaged.
Principle：Three locating pieces determine an equilateral triangle, the center of equilateral triangle and the axis coinciding of locating rod,
The locus of a steel ball is determined by locating rod top and three locating piece tops at 4 points.When steel ball is placed in locating rod top
During end, ensure the steel ball centre of sphere and locating rod axis coinciding by three locating pieces for forming equilateral triangle.
Application method (it is assumed that sphere centre coordinate is X, Y, Z, radius of a ball R)：
First, Primary Location：Fastener 1 is fixed on the steel pipe of scaffold, the survey using the top of locating rod 22 as the device
Set up an office, it is (X, Y, Z-R) to survey the theory three-dimensional coordinate to set up an office.Now the Primary Location position of the device sets position with final theoretical survey
Put deviation and 100mm is not to be exceeded.
2nd, connection spiral 6 is tightened, small standpipe chassis 8 and base plate 4 is bonded completely.
3rd, three foot screws 3 are rotated, make the bubble of circular bubble 14 placed in the middle, it is therefore an objective to ensure that base plate 4 is horizontal.
4th, survey is first found with in-site measurement instrument to set up an office (X, Y, (Z-R)), is then unscrewed connection spiral 6, is adjusted small standpipe
The position on chassis 8, it is (X, Y) to make the upper horizontal coordinate of locating rod 22, then tightens connection spiral 6.It is assumed that now clamp screw A24
It is in relaxation state with clamp screw B25.
5th, brake hoop A12 is pushed up, the teeth of brake hoop A12 upper ends is engaged with the teeth of the lower end of outer side sleeve 11,
Then clamp screw A24 screw rod is screwed into neck A26.Now clamp screw A24 is tight condition, and clamp screw B25 is to put
Loose state.
6th, rotate triangle frame 23 (now have between outer side sleeve 11 and intermediate casing 10 teeth constraint not can be movable relatively,
Can be movable relatively between small standpipe 9 and intermediate casing 10), triangle frame 23 drives outer side sleeve 11 and synchronous turn of intermediate casing 10
It is dynamic, because the small outer wall of standpipe 9 and the inwall of intermediate casing 10 have threaded engagement, so intermediate casing 10 rises when triangle frame 23 rotates
The upper parts of triangle frame 23 are driven to rise together including locating rod 22, the Z-direction coordinate etc. the top tip of locating rod 22 is (Z-R)
When stop operating triangle frame 23.
7th, brake hoop B13 is pushed up, is engaged brake hoop B13 upper ends and the teeth of the lower end of intermediate casing 10, then
Clamp screw B25 screw rod is screwed into neck B27, loosens clamp screw A24.Now clamp screw B25 is tight condition, brakes spiral shell
Rotation A24 is relaxation state.
8th, rotating triangle frame 23 (now has teeth constraint that relative transport can not occur between intermediate casing 10 and small standpipe 9
Dynamic, outer side sleeve 11 can rotate with triangle frame 23), because intermediate casing 10 is fixed from moving, so be attached thereto
Angular wheel B21 can not be moved, but angular wheel A20 and screw rod 19 can rotate, so as to drive locating piece 17 along screw rod 19
Moved with graduated scale 18.The steel ball of every kind of diameter has mark point on graduated scale 18.It is R to move to steel ball size for be positioned piece 17
Scale mark point when stop operating triangle frame 23, tighten clamp screw A24.
When the 9th, lifting the region that steel ball surrounds to the top of locating rod 22 and locating piece 17, steel ball under gravity, automatically
In place.So far the positioning work of a steel ball is completed.
In addition to the implementation, the utility model can also have other embodiment.It is all to use equivalent substitution or equivalent change
The technical scheme to be formed is changed, all falls within the protection domain of the requires of the utility model.
