The outer welding bead jig of wind power tower drum body circular seam
Technical field
The utility model relates to a kind of construction stage apparatus, is specifically related to a kind of platform that is used for the outer welding bead welding of circular steel structure cylindrical shell circumferential weld.
Background technology
In wind-power electricity generation pylon production process, the outer welding bead welding of cylindrical shell is difficulty very, it is bigger than interior welding bead welding degree-of-difficulty factor, danger coefficient is high, most of companies adopt rocker-arm to weld the frame welding automatically or adopt common platform fixed mount, this all exists welding inconvenient, the workman influences production efficiency easily from defectives such as cylindrical shell drop.
Summary of the invention
In order to overcome the problems referred to above that prior art exists, the utility model provides a kind of wind power tower drum body circular seam outer welding bead jig, and is esy to use, safe and reliable, can increase substantially efficiency.
The outer welding bead jig of the wind power tower drum body circular seam that the utility model provides, comprise main platform body, motor, gearbox, power transmission shaft, gearbox is connected with power transmission shaft, described gearbox has self-locking device, described main platform body is mainly by ledge, hoistable platform, lifting mechanism I and walking mechanism II form, described hoistable platform is provided with directional wheel, directional wheel is positioned on the both sides vertical beam of ledge, described lifting mechanism I comprises gear and roller chain, described gear is connected with power transmission shaft, described roller chain and gears engaged, the one end connects counterweight, and the other end is connected with hoistable platform; Described main platform body also comprises two tracks, lay respectively at the above and below of main platform body, described walking mechanism II comprises fixed wheel and roller, described fixed wheel is installed in the top of ledge, get on the right track and be positioned at the front of fixed wheel, described roller is installed in the bottom of ledge, lower railway be positioned at roller below, described roller is connected with power transmission shaft.
The outer welding bead jig of the wind power tower drum body circular seam that the utility model provides, compared with prior art its beneficial effect is: utilization elevating mechanism and walking mechanism are accurately located, need not to move continuously cylindrical shell, as long as move this jig by walking mechanism, not only save time, enhance productivity, but also guaranteed workman's safety.
