Description
Technical field
This utility model describes assembled blade tip clamping apparatus for examination and repair；The high-level localization method of blade tip；And positioning action method during blade tip installation.
Background technology
Rotor blade maintenance on wind turbine at present and the task that maintenance is time-consuming, relative risk and also costliness.The clamping device of prior art is usually made up of framework (also referred to as yoke) and many bands, these many bands are around at least some of winding of rotor blade, it is in place so that rotor blade is clamped, this relates to many human assistances, refer more particularly to small maintenance and the transformation of vane tip, appeal monoblock type dismounting will more time-consuming be taken a lot of work, it is the most frequent that the vane tip broken by lightning that present stage occurs and technology change vane tip, due to need to change blade tip is in irregular shape and also heavier-weight, maintainer stands in typical hanging basket, and on the height of regulation, maintenance will be extremely difficult, thus it is badly in need of a kind of blade tip coordinating hanging basket to use clamping apparatus for examination and repair, and blade tip clamping apparatus for examination and repair must highly precisely be oriented towards rotor blade, the blade tip that these needs are changed is fitted in rotor blade.Additionally, blade tip clamping apparatus for examination and repair must be artificially at high-altitude application, this relates to the work at a relatively high height, and technical staff operates from described hanging basket during the assembly or disassembly of blade tip.
In general, it is a subject matter that blade tip is connected to rotor blade, this is due to when blade tip clamping apparatus for examination and repair is placed on hanging basket and made blade tip be in tram relative on rotor blade direction, during this adjusts, it is necessary to carry out substantial amounts of manually adjusting.By handling crane or other lifting devices of blade tip clamping apparatus for examination and repair or passing through to utilize and the inside micro-positioning regulators of mobile blade tip clamping apparatus for examination and repair so that blade tip can be positioned relative to rotor blade.
It is required owing to visually controlling, so technical staff still must be close to the ongoing place of connection of blade tip clamping apparatus for examination and repair and rotor blade, this demand has to comply with maintenance requirement when rotor blade is positioned in high-altitude, that is, will by its from be in may considerably beyond installation blade tip at the at a relatively high height of 80 meters time, the most all the more so.Meanwhile, when make use of during the connection procedure of blade tip clamping apparatus for examination and repair and rotor blade positions, it is necessary to guarantee that rotor blade is not damaged by blade tip.
Summary of the invention
For the technical problem reaching the purpose of this utility model, solution presently, there are, the technical solution adopted in the utility model is:
This utility model provides a kind of assembled blade tip clamping apparatus for examination and repair, this assembled blade tip clamping apparatus for examination and repair includes base platform, is set up in base platform scissors lift table and is arranged on scissors lift table the workbench clamping blade tip, first base platform base platform is formed by connecting by front side board, back side panel, level table, guide wheel, hand winch, base platform is fixed on the guardrail left and right sides of work hanging basket by pressing plate, base platform horizontal plane leaves oblong aperture to facilitate blade tip to pass and to be provided with guide rod support and wheel bracket.Next scissors lift table includes that symmetrical frame type framework is bolted into have and moves up and down " shears " type structural member, scissors lift table is provided with guide post, horizontal guide sheave, lifting directive wheel etc., and described scissors lift table is set up on base platform and does left and right linear motion by horizontal guide sheave along guide post.The square cubic structure that workbench main body is enclosed by crossbeam and longeron again forms, stereochemical structure upper strata four direction is provided with four fixed hooks, loop chain and is linking up with equidirectional corresponding four hand winch that is provided with, and top, stereochemical structure four sides is provided with leading block and can vertically move along the longeron of scissors lift table.
Blade tip clamping apparatus for examination and repair is embodied as the position clamping blade tip of the longitudinal extension along wind turbine blade.Simultaneously in order to must essentially horizontally keep when keeping such blade tip clamping position of apparatus for examination and repair, shape and mechanism to make carrying the nacelle device of blade tip clamping apparatus for examination and repair.nullIn order to can guarantee that blade tip can be with wind turbine blade co-located，Can be realized by following: make blade tip clamping apparatus for examination and repair be fixed on the interior side rail top of work hanging basket by the pressing plate of base platform，Blade tip upper end hanging point is connected fixing with workbench by four hooks with loop chain，Keep blade tip side on the table，Blade tip lower end hanging point is connected with the steel wire rope in workbench hand winch，Ensure that the center of gravity of blade tip is in plummet state，Hanging basket reaches wind turbine blade front position by elevator crane gear，At this moment blade tip is carried out angle adjustment，Blade tip lower end four direction hanging point is connected to corresponding hand capstan respectively by steel wire rope，By the hand capstan of four direction steel wire rope tightened up and loosen the angle that can adjust blade tip relative to vertical direction，Pass through angle adjustment，Make the position of longitudinal extension of blade tip and wind turbine blade in the same direction，At this moment by the hand capstan of base platform front end, steel wire rope tightened up and loosen the upper-lower height that can adjust scissors lift table，To reach to adjust blade tip upper-lower height，Make blade tip and the fully mated installation of wind turbine blade.
The loop chain of blade tip clamping apparatus for examination and repair employing and being flexible coupling that steel wire rope positions, so make its blade tip when blade tip clamping apparatus for examination and repair is carried out in the adaptation procedure with rotor blade or bonding station, it is allowed to the motility of increase.Once blade tip clamping device is positioned in below rotor blade, the direction of blade tip then can be accurately controlled by hand capstan and guide post, at this time by artificial manual fine-tuning, make blade tip self adaptation adaptive with rotor blade, and adaptation install after can the time of staying longer, in other words, blade tip clamping apparatus for examination and repair due to its higher motility thus allow to be connected to blade tip described blade tip clamping apparatus for examination and repair faster, be easier to and also safer process.
The technical solution of the utility model is effectively reduced maintenance difficulty, it is adaptable to overhauls frivolous board, complicated applied environment, and has transport, simple in construction, easy to operate, safety high easy to assemble, good.
