Abstract
The utility model provides a wind power tower and flange installation platform mainly composed of a concrete round platform and a casting working platform. The concrete round platform is arranged at the bottom, and a concrete round platform periphery plate is arranged on the periphery. The casting working platform is laid on the upper portion of the concrete round platform, and the planeness of the casting working platform is smaller than or equal to 0.2 mm. The casting working platform is divided into multiple sector-shaped division pieces. Each sector-shaped division piece is provided with 2-4 inverted-T-type grooves toward the circle center and provided with a fixed lug plate in the radial direction, and the fixed lug plates are fastened through embedded bolts on the concrete round platform. Inner baffles are welded to the inner circles of the sector-shaped division pieces, and outer baffles are welded to the outer circles of the sector-shaped division pieces and welded to the periphery plate of the concrete round platform. The wind power tower and flange installation platform has the advantages that a wind power tower and a flange are convenient to assemble and weld, repeated utilization can be achieved, it is guaranteed that the planeness of the welded flange is 100% qualified, correcting work in the follow-up processes is omitted, working efficiency is improved, and labor intensity is greatly relieved.
Description
Technical field
The utility model relates to a kind of wind-power tower and flange mounting equipment.
Background technology
Wind-power tower is taper barrel weldment, segmentation manufacture, tens meters of every section of height, every section of internode adopts flange to connect, in making, the control of planeness of flange is most important, be applied in group to, weld, proofread and correct in whole process, planeness of flange is final to be required as 0.5-2mm, especially the requirement of epimere flange is the most sternly≤0.5mm, and do not allow to turn up, generally taked to level up group right, the method for tightly welding, effect is not satisfactory, and subsequent handling needs a large amount of corrections.
Summary of the invention
The purpose of this utility model is to provide a wind-power tower flange mounting platform, is suitable for different-diameter flange and tower wound packages is joined, and guarantees that assembly welding rear flange flatness reaches technical requirement control range.
The utility model is mainly made up of concrete round platform, foundry work platform, and bottom is 180-220mm concrete round platform, and periphery arranges thickness 18-22mm concrete round platform peripheral board; The thick foundry work platform of 180-220mm is laid on concrete round platform top, the flatness≤0.2mm of foundry work platform, and foundry work platform outside dimension is Φ 4500-5500mm, internal diameter size is Φ 1500-2200mm; Foundry work platform is divided into some fan-shaped bursts, every fan-shaped burst is 18-22 degree, interval 8-12 degree is uniform, every fan-shaped burst outer is provided with 2-4 bar towards center of circle direction and falls T-shape slot, the upper end open of falling T-shape slot 47-53mm, high 37-43mm, lower ending opening 62-68mm, dark 32-38mm; Every fan-shaped burst radially arranges fixing otic placode, fastening by the pre-embedded bolt on concrete round platform; Fan-shaped burst inner ring welding Internal baffle, outer ring is provided with outer baffle and the welding of concrete round platform peripheral board.
Adopt good effect wind-power tower of the present utility model and flange welding convenient operation, can reuse, guaranteed the flatness of welding rear flange, reach 100% qualified, reduced the correction work in subsequent handling, operating efficiency improves, and labour intensity reduces greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated:
Fig. 1 is structural representation of the present utility model;
T-shape slot, 6 fixing otic placodes, 7 pre-embedded bolts, 8 Internal baffles of 1 concrete round platform, 2 concrete round platform peripheral boards, 3 foundry work platforms, 4 outer baffles, 5 in figure.
The specific embodiment
As shown in the figure, bottom is 180-220mm concrete round platform 1, and periphery arranges thickness 18-22mm concrete round platform peripheral board 2; The thick foundry work platform 3 of 180-220mm is laid on concrete round platform 1 top, the flatness≤0.2mm of foundry work platform 3, and foundry work platform 3 outside dimensions are Φ 4500-5500mm, internal diameter size is Φ 1500-2200mm; Foundry work platform 3 is divided into some fan-shaped bursts, every fan-shaped burst is 18-22 degree, interval 8-12 degree is uniform, every fan-shaped burst outer is provided with 2-4 bar towards center of circle direction and falls T-shape slot 5, T-shape slot 5 upper end open 47-53mm, high 37-43mm, lower ending opening 62-68mm, dark 32-38mm; Every fan-shaped burst radially arranges fixing otic placode 6, fastening by the pre-embedded bolt 7 on concrete round platform 1; Fan-shaped burst inner ring welding Internal baffle 8, outer ring is provided with outer baffle 4 and welds with concrete round platform peripheral board 2.
When use, according to flange diameter, flange is placed in to the position that foundry work platform 3 is suitable, makes it fixed, tight with foundry work platform 3 with service bolt, the flatness of control flange neck, hangs in shell ring and docks with neck flange.Before docking, should check circularity, orifice plane degree and the girth of shell ring, guarantee shell ring and the poor 3.0mm that is not more than of flange girth; Group to after carry out CO
2gas shield backing welding, backing welding is taked equidistant segmentation bottoming method, interrupted, be symmetrically welded, until the bottoming of whole piece circumferential weld completes, its weld seam should be regular, even, postwelding is cleared up in time welding and is flown.
