A kind of double-vane walking hoistable platform
Technical field
The invention belongs to wind power plant equipment field, particularly a kind of blower fan tower barrel encircling welding equipment.
Background technology
Wind-power tower mainly plays a supportive role in wind power generating set, and simultaneously stability unit shakes.And in the production of blower fan tower barrel, one of most important link is exactly the welding of tower cylinder circular weld.During original welding circular weld, utilize crane gear Lincoln weld dolly to be winched to place to be welded, tower cylinder top, adjust little truck position, it is made to keep balance under gravity, welding tractor is walked at pylon circumferential weld place, tower cylinder rotates along with opposite direction made by welding swing roller frame simultaneously, thus realizes the welding of tower cylinder circumferential weld.Preparation before girth welding is loaded down with trivial details, complicated, the quality of weld seam is subject to two motor (vibrations) impacts, therefore there is inefficiency, operating difficulties, easily produce mass defect, again because tower cylinder diameter is larger, weld job height, apart from ground 3-6 rice, has the problems such as certain potential safety hazard to operating personnel's personal safety.
This welding tooling is for solving tower cylinder external circular seam welding procedure technology problem.Tower cylinder is that conical and different tower section tower cylinder diameter is different, the relative ground elevation of each weld seam of same tower cylinder is uneven not at sustained height, the length of tip is fixing, because welding tooling can not be close to weld seam to be welded, vibrations when therefore submerged arc welding carriage is walked in frock can affect the shaping of weld seam.One Fans pylon is generally made up of 3 sections or four sections, each section is made up of several sections of shell rings again, often weld one section just to need to reappose tooling device, no matter be circumferential weld or longitudinal seam welding, all there is the problem that a workman can only look after a station, this also governs the welding efficiency of tower cylinder to a certain extent.Therefore inefficiency, easily produce mass defect.
In order to overcome above problem, needing to find a kind of new method or device, setting about from efficient, convenient, energy-conservation, safety, guarantee weldquality, fundamentally solving blower fan pylon ring longitudinal seam welding Problems existing.
