Description

Large part hoisting device in wind power hub
Technical Field
The utility model relates to the field of wind power hoisting, in particular to a hoisting device for large parts in a wind power hub.
Background
With the maturity of wind power manufacturing and operation technology, the power of a wind turbine generator set is continuously increased, large parts in a wind turbine hub are more precise, and once the quality of large parts in the hub is in a problem due to the fact that the wind turbine hub is at the high altitude of 90-150 meters, an ultra-large crawler crane is needed for onshore large megawatt wind turbine generator set replacement according to the prior art, and a large offshore crane, a large offshore floating crane or a self-elevating ship can be used for offshore wind turbine generator set large part replacement. Not only will produce huge restoration replacement cost, still can reduce most part stability because the crane is easily influenced by factors such as artifical proficiency, wind speed. There is therefore a need in the art for a reliable device that provides stable lifting performance.
Currently, for the replacement of large parts in a wind power hub, 2 solutions are commonly used in the industry.
In the first solution, the crane is used directly to lift the large part to be replaced on the ground into the hub. The scheme has the problems that the price of a crane is very high, the hoisting price of a single fan is about 60-70 ten thousand yuan, and most parts in the hub cannot be kept stable and are easy to scrape in the process of passing through a side hole of the air guide sleeve from the outside. When large components within the hub are suspended from the ground or nacelle onto the hub, safety hazards may result from the overall structural instability.
For example, the application number CN201420244492.4 discloses a multipurpose hoisting tool for a wind turbine generator, which comprises a supporting frame, wherein the supporting frame is provided with a plurality of hoisting post holes, hoisting posts are arranged in the hoisting post holes, the lower ends of the hoisting posts are fixed in the hoisting post holes through hoisting post locking nuts, the direction of a hoisting point can be adjusted according to the gravity center requirement of the hoisting point of a hoisting machine, so that the requirement of different hoisting machines of a hoisting hook or a plurality of hoisting hooks can be met, the tool has the problem that the tool is lifted by a crane to move, and large parts in a hub cannot be stably maintained in the process of passing through a side hole of a flow guide cover from the outside, and are easy to scrape.
For example, the writing of "a combined hot galvanizing hoisting tool" of application number CN 202020435443: the utility model relates to the technical field of hot galvanizing equipment and discloses a combined hot galvanizing hoisting tool which comprises a driving device, support columns and a hoisting device, wherein the driving device is of a cuboid structure, the support columns are arranged at the bottom of the driving device, the tops of the support columns are fixedly connected to the bottom of the driving device, guide rails are respectively arranged on two sides of the front surface of the driving device, the support columns are respectively arranged at the bottoms of the other ends of the two groups of guide rails, and the support columns are fixedly connected with the bottoms of the guide rails. The tool has the problems that the tool cannot be stably combined with the tooth surface of the hub, and the tool cannot provide stable support for the hoisting process.
Such as application number CN 201220011209.4. A maintenance structure for a hub of a megawatt wind generating set belongs to the technical field of wind generating sets. A first hoisting hole is formed in the position, close to the main shaft, of the hub, the variable pitch speed reducer is arranged in the vertical direction of the first hoisting hole, a second hoisting hole and a hoisting opening are respectively formed in the front end variable pitch system of the air guide sleeve and the front end variable pitch system of the engine room cover, and the crane is arranged in the engine room. This frock can be in the wheel hub is hoisted to the major part that needs to be changed in the cabin, but can't guarantee to keep stable when major part passes through the kuppe side opening, takes place the scraping easily.
According to the second scheme, a large part to be replaced is hoisted into the engine room by using the self-hoisting machine of the fan, and then the tool and the engine room are connected into a whole by using connecting modes such as bolts and the like, so that the large part is hoisted into the hub from the engine room as a load. The problem of this scheme lies in that mainstream frock can only be applicable to single operating mode in the market, can't act on multiple operating mode.
For example, the application number CN201721675290.5 discloses a maintenance, replacement and transportation tool for a variable pitch speed reducer for a wind generating set, which comprises a first support, a second support, a third support, a cross beam, a linear slide rail, a roller assembly and a chain block. The tool can only hoist large parts in the engine room into the wheel hub, and when the crane hoists large parts on the ground out of the wheel hub, the tool cannot cooperate with the crane to hoist the large parts into the wheel hub, so that the tool can only be applied to a single working condition.
For example, application No. CN202022011868.5 is a lifting adjusting device for wind driven generator, which comprises two blade clamps, a tower top bracket and a lifting beam; a lifting machine is arranged above the tower top support and is connected with the fixed disc through a lifting rope; the hanging beam comprises a rotating frame, a bearing inner ring, a bearing outer ring and a fixed disc, a gear rack is arranged on the inner side of the bearing inner ring, a driving motor is installed on the fixed disc, and the driving end of the driving motor is meshed with the gear rack through a gear; two sides of the upper surface of the rotating frame are connected with winches which are connected to the blade clamp through steel wire ropes. The tool can only hoist large parts needing to be replaced on the ground into the hub, and cannot hoist the large parts in the engine room into the hub.
