Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in further detail.
The present embodiment is taking transmission line of electricity emergent repairing tower base as example, as shown in Figure 2 to Figure 3, and the power transmission line that the embodiment of the present invention providesRoad emergent repairing tower base point comprises: flap 1, basis 2, pivot pin 3, tower body 4, bolt 5. Basic 2 levels are arranged on groundFace, fixes by the fixing hole of four jiaos of basic 2 bottom surfaces, inserts pivot pin 3 after flap 1 are docked with the pin-and-hole of basic 2 end faces,Open flap 1, make flap 1 and the angle of basic 2 end faces remain on 90 °, by the emergent repairing tower tower body of horizontal positioned 4 withAfter the pedestal docking of flap 1, be bolted to connection, establish emergent repairing tower tower body 4, flap 1 rotate straight around pivot pin 3To fitting with basic 2 end faces, now flap 1 are 0 ° with the angle of basic 2 end faces, at flap 1 and basic 2 end facesCorresponding through hole in construction bolt 5 fastening, so far emergent repairing tower tower body 4 is established on base.
Emergent repairing tower base folding paper syndeton provided by the invention is with the difference that is articulated and connected of tradition, and folding paper structure is fullFoot is established and when the functional requirement of the tower body that fell, has greatly been simplified the version of parts, and, reduce the number of partsMeasure, improved the unfailing performance of structure. On the other hand, after emergent repairing tower has been established, the lower end the way of restraint of whole tower structure to some extentDifference, traditional being articulated and connected is similar to and is articulated and connected, and folding paper syndeton provided by the invention is fixed by connecting bolt,For fixed constraint connects, for the feature of long fine texture pressure-bearing, folding paper syndeton provided by the invention is more conducive to improve wholeThe pressure-bearing critical load of body structure.
Application Euler's formula represents the critical load of elongated compressed structure:
In formula, π is constant, and E is relevant to material properties, and I is the geometric attribute relevant to tower body cross section, the height that l is tower,μ is the length factor relevant to end restraint condition.
Under material and the measure-alike condition of emergent repairing tower, emergent repairing tower top is fixed by bracing wire, belongs to hinged. Traditional repairingTower tower body lower hinge bearing is hinged, μ value 1.0; And folding paper of the present invention connects, emergent repairing tower tower body bottom and baseFor clamped, μ value 0.7; Hence one can see that, traditional end of critical bearing capacity ratio of the emergent repairing tower base that the embodiment of the present invention providesSeat has improved about 2 times.
