Description
Technical field
The present invention describes assembly type 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
Current maintenance of the rotor blade on wind turbine is time-consuming, relative risk and also expensive task with maintenance.The clamping device of prior art is usually by framework（Also referred to as yoke）With many band compositions, the many bands are wound around at least a portion of rotor blade, it is in place so that rotor blade to be clamped, this is related to many human assistances, more particularly to small maintenance and the transformation of vane tip, appeal monoblock type dismounting more time-consuming will be taken a lot of work, it is very frequent that the vane tip broken by lightning occurred at this stage changes vane tip with technology, because the blade tip for needing to change is in irregular shape and heavier-weight, maintenance personal overhauls at station in typical hanging basket in defined height will be extremely difficult, thus it is badly in need of a kind of blade tip for coordinating hanging basket to use clamping apparatus for examination and repair, and blade tip clamping apparatus for examination and repair must be highly precisely oriented towards rotor blade, so that the blade tip that the needs are changed is fitted in rotor blade, in addition, blade tip clamping apparatus for examination and repair must be artificially in high-altitude application, this is related to the work at a relatively high height, technical staff is operated during the assembly or disassembly of blade tip from the hanging basket.
In general, it is a subject matter that blade tip is connected into rotor blade, this is due to when blade tip clamping apparatus for examination and repair is placed on hanging basket and blade tip is in correct position on relative to rotor blade direction, during this adjustment, it is necessary to carry out substantial amounts of manually adjust.The crane or other lifting devices of apparatus for examination and repair are clamped by manipulating blade tip or by using the inside micro-positioning regulators that apparatus for examination and repair is clamped with mobile blade tip so that blade tip can be positioned relative to rotor blade.
Because visually control is required, 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, the demand is positioned in high space-time in rotor blade and has to comply with maintenance requirement, that is, by its from be in may be considerably beyond the installation blade tip at 80 meters of at a relatively high height when, then it is even more so.Meanwhile, during it make use of blade tip to clamp the connection procedure of apparatus for examination and repair and when rotor blade is positioned, it is necessary to ensure that rotor blade is not damaged by blade tip.
The content of the invention
To achieve the object of the present invention, the technical problem that presently, there are is solved, the technical solution adopted by the present invention is：
The present invention provides a kind of assembly type blade tip clamping apparatus for examination and repair, assembly type blade tip clamping apparatus for examination and repair includes base platform, it is set up in the workbench that base platform fixes skeleton and blade tip is clamped on fixed skeleton, base platform base platform first is by front side board, back side panel, level table, guide wheel, hand winch is formed by connecting, base platform is fixed on the guardrail left and right sides of work hanging basket by pressing plate, oblong aperture is left on base platform horizontal plane to facilitate blade tip to pass through and be provided with guide rod support and wheel bracket, secondly fixed skeleton includes the square cubic structure enclosed by crossbeam and longeron, stereochemical structure is provided with guide rod, horizontal guide sheave, lift directive wheel etc., the fixed skeleton is set up on base platform and does left and right linear motion along guide rod by horizontal guide sheave, the square cubic structure composition that workbench main body is enclosed by crossbeam and longeron again, stereochemical structure upper strata four direction is provided with four fixed hooks, loop chain and link up with it is equidirectional be provided with four corresponding hand winches, stereochemical structure four sides top is provided with leading block and can vertically moved along the longeron of fixed skeleton.
Blade tip clamping apparatus for examination and repair is embodied as clamping blade tip along the position of the Longitudinal extending of wind turbine blade；While in order to keep position, shape and the mechanism of such blade tip clamping apparatus for examination and repair so that carrying blade tip must essentially horizontally be kept when clamping the nacelle device of apparatus for examination and repair.In order to can guarantee that blade tip can be realized with the same position of wind turbine blade by following：Blade tip is set to clamp the interior side rail top that apparatus for examination and repair is fixed on work hanging basket by the pressing plate of base platform, blade tip upper end hanging point is connected 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 angle adjustment is carried out to blade tip, blade tip lower end four direction hanging point is connected to corresponding hand capstan respectively by steel wire rope, pass through the hand capstan of four direction tightening up and loosening and can adjust angle of the blade tip relative to vertical direction to steel wire rope, pass through angle adjustment, make the position of the Longitudinal extending of blade tip and wind turbine blade in the same direction, at this moment the hand capstan of fixed skeleton front end tightening up and loosening and can adjust blade tip upper-lower height to steel wire rope is passed through, so that blade tip and the fully mated installation of wind turbine blade.
Loop chain and being flexible coupling that steel wire rope is positioned that blade tip clamping apparatus for examination and repair is used, so make its blade tip when blade tip is clamped in adaptation procedure or bonding station of the apparatus for examination and repair progress with rotor blade, allow increased flexibility, 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 rod, at this time pass through artificial manual fine-tuning, so that blade tip is adaptively adapted to rotor blade, and being adapted to can be longer with the residence time after installing, in other words, blade tip clamps apparatus for examination and repair due to its higher flexibility to allow blade tip being connected to the blade tip clamping apparatus for examination and repair faster, easily and also safer process.
Technical scheme is effectively reduced maintenance difficulty, it is adaptable to overhaul frivolous board, complicated application environment, and with easy to assemble, good luck it is defeated, simple in construction, easy to operate, it is safe the features such as.
