Abstract
The utility model relates to a safe operation platform for welding the door frame of a wind turbine tower frame, which comprises a wind turbine tower barrel, and is characterized in that: a first platform and a second platform are arranged on two sides in the center of the door frame of the wind turbine tower barrel respectively and are connected with each other through a connecting plate; and at least one permanent magnet is arranged at the contact positions of the first platform and the second platform and the wind turbine tower barrel. The safe operation platform has the advantages that: the safety level during welding is improved, the life safety of welders and welding quality are ensured, the labor intensity of the welders is reduced, and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of arc-shaped surface safe operation platform, relates in particular to a kind of security platform that is used for the welding of windmill tower frame doorframe.
Background technology
Wind resource is very abundant on the earth, and wind energy more and more is subject to people's attention as a kind of cleaning, non-pollution of renewable energy, thereby wind-power electricity generation becomes one of regenerative resource exploration project of countries in the world common concern.
The section diameter is general more than 4 meters at the bottom of the MW class Large-scale Wind Turbines pylon, national Specification: " all eminences that (containing 2m) might fall more than height of fall datum level 2m are carried out operation, all are called high-rise working." to stand on the cylindrical shell more than 4 meters the welding doorframe very dangerous for the welder; accidentally personnel are easy to fall from the cylinder of eminence; cause casualties; for the condition of work of improving the welder and guarantee welding quality, are necessary to design a kind of security platform that is used for the welding of windmill tower frame doorframe.
Summary of the invention
The utility model technical issues that need to address have provided a kind of safe operation platform that is used for the welding of windmill tower frame doorframe, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: wind energy conversion system tower tube; Doorframe central authorities both sides at described wind energy conversion system tower tube are settled first platform and second platform respectively; Described first platform and second platform join by a plate; Contact position at first platform and second platform and wind energy conversion system tower tube is settled at least one permanent magnet respectively.
Compared with prior art, the beneficial effects of the utility model are: both improved the safe class when welding, guaranteed welder's life security, guaranteed the quality of welding again, reduced welder's labour intensity, improved production efficiency.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is a vertical view of the present utility model.
Fig. 3 is a side view of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
By Fig. 1, Fig. 2, Fig. 3 as seen: the utility model comprises: wind energy conversion system tower tube 9; Doorframe central authorities both sides at described wind energy conversion system tower tube 9 are settled first platform 1 and second platform 2 respectively; Described first platform 1 and second platform 2 join by a plate 3; Settle at least one permanent magnet 5 at first platform 1 and second platform 2 respectively with the contact position of wind energy conversion system tower tube 9.
Described first platform 1 and second platform 2 are respectively a framework.
Screw with first platform 1 and second platform, 2 different distance is set respectively on described connecting plate 3, forms the width of integral platform in order to regulate first platform 1 and second platform 2.
Described permanent magnet 5 is placed on the adjustable plate 4; Described adjustable plate 4 is connected with wind energy conversion system tower tube 9.
The doorframe welding process is as follows:
1, at first polishing must be cleared up with scale removal in the weld metal zone, and rust staining, gas cutting slag, grease and other dirts also keep dry.
2, begin to require before the welding that doorframe and tower body are welded the abundant preheating of two sides and reach welding process requirement to guarantee preheat temperature.
3, the welding method of doorframe and tower body adopts manual electric arc welding or gas shielded arc welding; because doorframe and end section tower body thickness are thicker; welding procedure generally is multi-pass welding and connects, and behind the weld defect of one deck, descends the welding of one deck again before must repairing earlier since the 2nd layer.Require the complete penetration of weld seam, do not have leak weld, burn, defective such as crackle, slag inclusion and face of weld should be smooth, smooth, be shaped well.
4, the welding of doorframe must be in horizontal level, to help guaranteeing weldquality, improves speed of welding.
In sum, doorframe and tower body welding requirements height, workload is big, the time is long.The welder stands on the circular cylinder body for a long time, and more than 4 meters, potential safety hazard is very big again for diameter.
The structure of the utility model security platform:
1, security platform by about 2 platforms connect into an integral platform (as shown in Figure 3) by connecting plate and bolt 6, nut 7 and packing ring 8.
2, two platforms respectively have 4 apertures about, by the width of connecting plate 3 adjustable platform, to adapt to the width requirement of different door frames.
3, whole security platform is held on the cylindrical shell about doorframe by two permanent magnets, with fixing whole security platform above the pylon cylindrical shell.
4, because tower tube diameter has nothing in common with each other, and the short transverse of magnet 5 can be adjusted, it is the adjustment that realizes the magnet short transverse by the slotted hole in the adjustable plate that welds together with magnet.Thereby guarantee that magnet holds cylindrical shell.
