Abstract
The utility model relates to a mounting tool for blade root flanges in wind generating sets. The mounting tool comprises a support base. A fork entry hole is arranged in the support base along the length-wise direction thereof. Locking bolts matching with a fork are arranged at the bottom of the support base. A vertical plate arranged in the vertical direction is disposed on the upper surface of the support base. A crane lifting hole is arranged in the top of the vertical plate. Three flange hanging rods fixedly connected with the vertical plate are disposed on the support base along the length-wise direction. The flange hanging rods are in one-to-one correspondence with holes arranged in a blade root flange. Distances from the flange hanging rods to the support base are larger than those from the holes of the blade root flange to an inner ring of thereof. The blade root flange and the mounting tool are integrally connected by inserting the flange hanging rods into the flange, the blade root flange is lifted with a crane through the crane lifting hole, the fork is inserted into the fork entry hole, and the fork of a forklift is moved so as to position and install the blade root flange. The mounting tool is simple in structure, convenient and quick to mount, and safe and reliable.
Description
Technical field
The utility model relates to a kind of mounting tool, particularly a kind of mounting tool for wind generator set blade flange at bottom.
Background technology
Along with the development of wind power technology, continually developing of wind field resource, all proposes higher requirement to blower fan and blade, and low wind speed, powerful blower fan are more and more subject to the favor in market.In order to obtain lower incision wind speed, blade becomes more and maximizes, and this ability to blade bearing capacity and antifatigue is had higher requirement.In order to improve carrying and the anti-fatigue ability of blade, conventionally between blade and wheel hub pitch variable bearings, increase the root of blade flange of a steel, flange is fixed by screws on pitch variable bearings.Because this step starts completing after hubcap assembling, pitch variable bearings is also in hubcap inner side, and the installed surface of flange and hubcap have a segment distance at vertical direction, cannot be with the installation of directly slinging of driving a vehicle.Directly use guide rod that the phenomenon of blocking because of the excessive frequent generation flange of length and guide rod is installed also, bring difficulty to assembling.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of simple in structure, the mounting tool for wind generator set blade flange at bottom safely and fast easy to use.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of mounting tool for wind generator set blade flange at bottom, be characterized in: comprise base for supporting, in base for supporting, be provided with pallet fork patchhole along its length direction, be provided with the clamping screw coordinating with pallet fork in the bottom of base for supporting, on the upper surface of base for supporting, be provided with the riser of vertical setting, the top of riser is provided with driving lifting eye, be provided with 3 flange suspension rods that are fixedly connected with riser along the length direction of base for supporting, 3 root flange suspension rods are corresponding one by one with the hole on root of blade flange, flange suspension rod is greater than the distance of the Kong Zhiqi inner ring on root of blade flange apart from the distance of base for supporting.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the described mounting tool for wind generator set blade flange at bottom, is characterized in: between riser and base for supporting, be provided with reinforcement.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the described mounting tool for wind generator set blade flange at bottom, be characterized in: described clamping screw is provided with 2, along the length direction setting of pallet fork patchhole.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and the described mounting tool for wind generator set blade flange at bottom, is characterized in: on the outer end of flange suspension rod, clamp nut is housed.
The utility model penetrates flange by 3 root flange suspension rods, flange and this device are connected as a single entity, then utilize driving by the driving lifting eye flange of slinging, after pallet fork inserted to pallet fork insert in the hole, realize the location and installation work of root of blade flange by the movement of fork of forklift truck.Compared with prior art, this apparatus structure is simple, easy to use, convenient and swift when installation, safe and reliable.

Fig. 2 is the utility model and flange assembly structure schematic diagram.
Fig. 3 is mounting structure schematic diagram of the present utility model.
Detailed description of the invention
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1, a kind of mounting tool for wind generator set blade flange at bottom, comprise base for supporting 12, in base for supporting 12, be provided with pallet fork patchhole 5 along its length direction, be provided with the clamping screw 6 coordinating with pallet fork 8 in the bottom of base for supporting 12, clamping screw 6 is provided with 2, along the length direction setting of pallet fork patchhole 5.Use clamping screw 6 pallet fork 8 and this device firmly can be fixed together, guaranteed the safe and reliable of installation process.On the upper surface of base for supporting 12, be provided with the riser 3 of vertical setting, between riser 3 and base for supporting 12, be provided with reinforcement 4.The top of riser 3 is provided with driving lifting eye 7, be provided with 3 flange suspension rods 1 that are fixedly connected with riser 3 along the length direction of base for supporting 12,3 root flange suspension rods 1 are corresponding one by one with hole connected on root of blade flange 9, and therefore 3 root flange suspension rods 1 are that the radian that is certain distributes.Flange suspension rod 1 is greater than the distance of the Kong Zhiqi inner ring on root of blade flange 9 apart from the distance of base for supporting 12, facilitate flange to be lifted on flange suspension rod 1.Clamp nut 2 is housed on the outer end of flange suspension rod 1, can in the time of assembling, prevents the unexpected landing of flange 9, the security that has improved this device.
With reference to accompanying drawing 2 and 3, when assembling, under root of blade flange 9 levels, three root flange suspension rods 1 of this frock to be inserted in the hole on corresponding root of blade flange 9, back is fastening with thin clamp nut 2, anti-skidding.Penetrate the driving lifting eye 7 on riser 3 with shackle, suspender belt, utilize the driving on riser 3 that root of blade flange 9 is vertically sling.Fork truck drives to assigned address, lifts pallet fork 8, and pallet fork 8 height flush with pallet fork patchhole 5.Mobile driving makes pallet fork patchhole 5 in pallet fork 8 tips, and tightens clamping screw, prevents that pallet fork 8 from sliding, and then pulls down the suspender on driving lifting eye 7.After being ready to complete, slowly adjust position and the height of fork truck, ensure that flange 9 is concentric with hubcap 11 cylindricals.Fork truck moves ahead constantly near pitch variable bearings inner ring 10, makes flange 9 and pitch variable bearings hole positioned in alignment with guide post, unclamps the clamp nut 2 after three root flange suspension rods 1, tightly blade root flange 9 is fastened on the inner ring of pitch variable bearings with screw.Screw installs rear fork truck and retreats, and just can take out frock, completes the installation of blade root flange 9.
