Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, for a kind of embodiment positioning retention mechanism of this utility model, including fastening bolt 1, alignment pin 2, positioning seat 3 and at least one locating ring 4, simple in construction, easy for installation；Fastening bolt 1 bottom is provided with external screw thread, and fastening bolt 1 is fixed with snap ring 5, and snap ring 5 is to 2 barrier effects of alignment pin, and during installation, snap ring 5 can promote alignment pin 2 forward, prevents alignment pin 2 from moving；Alignment pin 2 becomes the cylinder of hollow, and alignment pin 2 one end becomes 30oPyramid, alignment pin 2 external diameter 76mm, compared to original external diameter 40mm with due to the indefinite situation of open-close ways different angles, present arrangement avoids due to the different situation of open-close ways different angles, unified set alignment pin 2 external diameter overstriking and most suitable 30oPyramid, is the most suitable length through operation setup and angle, makes to connect more firm stable simultaneously；Alignment pin 2 is internal is provided with taper unthreaded hole, it is easy to fastening bolt 1 passes through, and connects simple and convenient；Positioning seat 3 is the hollow cylindrical that diameter is more than alignment pin 2 external diameter, is 30 matched with alignment pin 2 tapered end face inside positioning seat 3 one endoPyramid curved surface, positioning seat 3 is internal is provided with the female thread matched with fastening bolt 1 external screw thread, and positioning seat 3 is connected by screw thread with fastening bolt 1, simple and convenient；Locating ring 4 is fixed on positioning seat 2 periphery, and during use, retainer ring 4 adjusts and stationary positioned seat 3 position；Alignment pin 2 tapered end thereof inserts the conical camber end of positioning seat 3, alignment pin 2 insertion depth is 45mm, meet shield lining ring concrete segment die to guide and positioning requirements, by being connected of alignment pin 2 and positioning seat 3, meet shield lining ring concrete segment die fastening function and positioning function；Fastening bolt 1 is through alignment pin 2 and positioning seat 3, alignment pin 2 and positioning seat 3 are linked together by fastening bolt 1, use fastening bolt 1 easy accessibility, the bed knife of fastening bolt 1, act on the conical surface of alignment pin 2 and positioning seat 3, the metamorphosis of fastening force offside model cavity panel is completely eliminated.
Fastening bolt 1 is the trapezoidal thread of Tr36 × 6, and pretightning force meets shield lining ring concrete segment die fastening force requirement, shortens the time of screwing simultaneously, improves the shield lining segment prefabricated production efficiency of ring concrete.
Locating ring 4 has two, and die main body 6 can be fixed more stable by two retainer ring 4.
Two parallel positioning seat 3 peripheries that are fixed on of locating ring 4, two locating rings 4 are not close to, and leave certain distance between two locating rings 4, and this distance depends on the size of die main body 6, conveniently positioning seat 3 position are adjusted and are fixed.
Use process:
As shown in Figure 2, alignment pin 2 is arranged in fastening bolt 1, positioning seat 3 is screwed in fastening bolt 1, promotion alignment pin 2 is entered in positioning seat 3 by the snap ring 5 in fastening bolt 1, mounted fastening detent mechanism is arranged in the preformed hole of shield lining ring concrete segment die, side form 7 is welded on alignment pin 2, the most first the locating ring 4 getting close to the ragged edge of die main body 6 is welded, backing out fastening bolt 1 and open mould, the locating ring 4 of the inner side of die main body 6 is got close in welding.
After using technique scheme, easy to use, the positioning function integrator of fastening function and detent mechanism, meets shield lining ring concrete segment die fastening function and positioning function simultaneously, increases orientational cone-shaped surface fit dimension, improve locating effect, reducing error, the bed knife of fastening bolt acts on the conical surface of alignment pin and positioning seat, eliminates the metamorphosis of fastening force offside model cavity panel, maintaining is convenient, improves work efficiency.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
