Detailed description of the invention
Below in conjunction with accompanying drawing 1 to accompanying drawing 5, the utility model is described further.
As shown in accompanying drawing 1 and accompanying drawing 4, this steel coal hopper abutting joint constructing operation platform, comprise annular for operative employee stand construction circle ring rack group 1 and be fixedly welded on the some hangers 2 in circle ring rack group 1, the external diameter of circle ring rack group 1 is than the little 1-1.5 rice of the internal diameter of steel coal hopper cylindrical section 9.As shown in Figure 5, when use, first utilize large-scale crane by also fixing to installation site the handling of cylinder cone section, then will make the operation platform of having assembled, and utilize large-scale crane that this steel coal hopper abutting joint constructing operation platform is passed through to hanger 2 handlings to steel coal hopper conical section 10 inside.Because steel coal hopper conical section 10 is pyramidal structure, therefore circle ring rack group 1 can be stuck in steel coal hopper conical section 10, realizes fixing.Use afterwards large-scale crane by 9 handlings of steel coal hopper cylindrical section to steel coal hopper conical section 10 tops, adjust hoist lifting hook position, make that steel coal hopper cylindrical section 9 end openings and steel coal hopper conical section 10 energy suitable for reading are identical to be docked.Constructor carries out steel coal hopper cylindrical section 9 end openings and steel coal hopper conical section 10 butt welding operation suitable for reading in circle ring rack group 1.After having welded, utilize large-scale crane by extremely next steel coal hopper conical section 10 inside of this steel coal hopper abutting joint constructing operation platform handling, to carry out next group installation work.Because this steel coal hopper abutting joint constructing operation platform is simple in structure, therefore make easily.Easy to assembly, not only raised the efficiency but also ensured with respect to the mode of building of scaffold to have shortened the safety of work high above the ground the construction period, and can repeatedly use.
As shown in accompanying drawing 2 and accompanying drawing 3, circle ring rack group 1 can be for following structure it comprise the outer ring 1.1 of the annular of being made by channel-section steel bending, the inner ring 1.2 of the annular made by channel-section steel bending, be connected in the some connecting rods 1.4 between outer ring 1.1 and inner ring 1.2, it is upper above with inner ring 1.2 that the diamond plate 1.3 of annular is fixedly welded on outer ring 1.1, and the external diameter of diamond plate 1.3 and internal diameter match with the external diameter of outer ring 1.1 and the internal diameter of inner ring 1.2 respectively.Because outer ring 1.1 and inner ring 1.2 are made by channel-section steel, therefore it is subject to force intensity high, has ensured reliability, between outer ring 1.1 and inner ring 1.2, is connected by some connecting rods 1.4, has further improved bonding strength.Therefore circle ring rack group 1 simple in structure, intensity is high, easily manufactured.Outer ring 1.4 is 400-600mm with the difference of the exradius of inner ring 1.2.If outer ring 1.4 is poor excessive with the exradius of inner ring 1.2, will cause the waste of the diamond plate 1.3 of laying, increased the weight of manufacturing cost and operating desk, and the too small space that will cause constructor to stand while construction of difference is too small, on the contrary construction working inconvenience.Therefore the difference that is arranged on 400-600mm is rational scope.
As shown in Figure 5, be fixed with soft cat ladder 11 in circle ring rack group 1, the lower end of soft cat ladder 11 contacts with ground.Constructor can, by the convenient climbing of soft cat ladder 11 to this steel coal hopper abutting joint constructing operation platform, further improve the convenience using.
Can also comprise some sleeves 3 of being along the circumferential direction vertically fixed on inner ring 1.2, be plugged in the vertical rod 4 on each sleeve 3 respectively, sleeve 3 and vertical rod 4 bottoms are respectively arranged with circular hole, bolt 7 is successively through the circular hole in sleeve 3 and vertical rod 4 fixing by nut 8, vertical rod 4 upper ends and middle part are respectively arranged with through wires hole, steel wire safety rope I 5 and steel wire safety rope II 6 are passed the through wires hole of each vertical rod 4 upper ends and middle part successively, and around the cast that forms sealing.Steel wire safety rope I 5 and steel wire safety rope II 6 around lopping can prevent that constructor from dropping from the endoporus of the inner ring 1.2 of this steel coal hopper abutting joint constructing operation platform, improved safety.
