Abstract
The invention discloses a steel-structure tensioning base, and aims to provide a steel-structure tensioning base, which is high in strength and stability, convenient to assemble and disassemble and reusable, for production of CRTS III type tensioning ballastless track slabs. The steel-structure tensioning base comprises tensioning bases, fixing bases, tensioning mechanisms, supporting mechanisms, tightening mechanisms and bolt connection assemblies. The steel-structure tensioning base is formed by welding and machining sheet metal, and is connected and fixed by bolts, the difficulty of the civil engineering construction is avoided, the time for factory building is shortened, it is simple and convenient for people to reuse the site for farming after completion of production, and the cost is lowered.
Description
Technical field the present invention relates to the production equipment of the pre-stretch-draw of a kind of CRTS type III without tiny fragments of stone, coal, etc. formula track plates, is specially the pre-stretch-draw of a kind of CRTS type III without the pretensioned steel construction stretching pedestal of the inner stretch-draw muscle of tiny fragments of stone, coal, etc. formula track plates.
Background technology, in order to adapt to the needs of Chinese Railway go-global strategy, must promote the autonomous innovation of Chinese non-fragment orbit technology, makes self brand of Chinese non-fragment orbit.For this reason, on the basis of summing up China existing non-fragment orbit research and apply experience, in conjunction with non-fragment orbit technology mathematical models again, research and develop and laid there is complete independent intellectual property right the pre-stretch-draw of CRTS type III without tiny fragments of stone, coal, etc. formula track plates.
Summary of the invention the object of the present invention is to provide a kind ofly manufactures that the pre-stretch-draw of CRTS type III is high without the intensity of tiny fragments of stone, coal, etc. formula track plates, stability strong, and the convenient steel construction stretching pedestal that can reuse of disassembly and assembly.
The present invention is sheet metal welding, machine add-on type, is fixed with bolts.There is high strength, the feature that simple installation fast can reuse, avoid the difficulty of civil engineering, shorten and found the factory the time, produce after terminating, easy to the second ploughing in its place, reduce required expense, substantially achieve environmental protection construction.
A kind of steel construction stretching pedestal of the present invention, it comprises stretch-draw pedestal, fixed pedestal, stretch-draw mechanism, supporting mechanism, tensioning mechanism and bolt connection assembly.
First stretch-draw pedestal and fixed pedestal are positioned over horizontal base in factory building above the ground, determine the relative position of each pedestal.Stretch-draw pedestal is divided into transverse stretching pedestal and longitudinal stretch-draw pedestal, and fixed pedestal is divided into horizontal fixed pedestal and longitudinal fixed pedestal, is connected and fixed between pedestal with high-strength bolt.
Stretch-draw mechanism is made up of stretch-draw beam, thrust beam, tensioning screw rod, locking nut and stretch-draw oil cylinder.Stretch-draw beam is put in above stretch-draw pedestal, is connected with locking nut by tensioning screw rod with thrust beam, and stretch-draw oil cylinder is bolted to outside stretch-draw pedestal, realizes stretch-draw action by thrust beam.
Supporting mechanism is made up of cross-brace beam, longitudinal bracing beam and Connection Block.By cross-brace beam, longitudinal bracing beam is connected fastening with Connection Block with bolt, and is bolted with stretch-draw pedestal and fixed pedestal, makes base interior form latticed support, adds the intensity of pedestal, prevent its stress deformation.
Tensioning mechanism is installed on base bottom, base bottom is strained to the inside by the nut at pull bar two ends, and during minimizing stretch-draw beam work, pedestal is to the active force of foundation bolt.
The present invention adopts metal structure, is bolted between parts.Relative to traditional reinforced concrete structure, achieve the recycling of equipment, and greatly reduce the difficulty of construction on facility floor basis, decrease the amount of reinforcement of ground base inside, thus shorten the workshop building duration, reduce construction cost.
Description of drawings 1 is front view of the present invention;
Fig. 2 is the A-A place sectional view of Fig. 1;
Fig. 3 is the B place enlarged drawing of Fig. 2.
In figure, sequence number is: 1. horizontal fixed pedestal, 2. longitudinal stretch-draw pedestal, 3. transverse stretching pedestal, 4. longitudinal fixed pedestal, 5. longitudinal stretch-draw beam, 6. thrust beam, 7. transverse stretching beam, 8. tensioning screw rod, 9. stretch-draw oil cylinder, 10. locking nut, 11. longitudinal bracing beam A, 12. longitudinal bracing beam B, 13. longitudinal bracing beam C, 14 cross-brace beam A, 15. cross-brace beam B, 16. cross-brace beam C, 17. Connection Blocks, 18. longitudinal ties, 19. cross-ties, 20. nuts, 21. connecting bolts.
The invention will be further described below in conjunction with accompanying drawing for detailed description of the invention; By horizontal fixed pedestal 1, transverse stretching pedestal 3, longitudinal stretch-draw pedestal 2 and longitudinal fixed pedestal 4 are laid according to its relative position, connect between pedestal with high-strength bolt.
Longitudinal stretch-draw beam 5 and transverse stretching beam 7 are put on longitudinal stretch-draw pedestal 2 and transverse stretching pedestal 3 respectively, are connected and fixed by tensioning screw rod 8, locking nut 10 and thrust beam 6; Stretch-draw oil cylinder 9 is connected with pedestal and thrust beam 6 respectively, is realized the stretch-draw action of stretch-draw beam by the pushing tow of stretch-draw oil cylinder 9.
Base interior is provided with supporting mechanism, and by longitudinal bracing beam A, longitudinal bracing beam B, longitudinal bracing beam C, cross-brace beam A, cross-brace beam B, cross-brace beam C is connected with Connection Block 17 according to its relevant position, fixes with connecting bolt 21.
Longitudinal tie 18 and cross-tie 19 are arranged on base bottom, lock with nut 20, base bottom tension is gained in strength.
