Abstract
The utility model relates to a hub converter cabinet body, which comprises three branch cabinet bodies with fan-like cross sections, wherein the outer peripheries of the bottoms of the branch cabinet bodies are all provided with arc flanges, light holes are distributed on each arc flange, the branch cabinet bodies are fastened into a whole body via bolt components, one side of the branch cabinet body, which is opposite to the outer arc surface of the branch cabinet body, is provided with an ear plate provided with through holes, and the through holes of the ear plates are corresponding to three connecting holes on a slip ring support on a hub casting. The utility model has the advantages of structure simple, convenient installation, safety, reliability, easy maintenance and low maintenance cost, the connecting holes for installing the cabinet body are all arranged outside the cabinet body, and when hoisting is carried out, the cabinet door does not need to be opened when tightening the screws or striking moment; and during hoisting or maintenance, all the electronic and electric elements in the cabinet body are not affected. The holes on the arc flange can align with a stud on the top of the hub casting as long as three hoisting screws align with the three connecting holes on the hub slip ring support.
Description
Technical field
The utility model relates to a kind of wheel hub unsteady flow cabinet cabinet, especially relates to the wheel hub unsteady flow cabinet cabinet in a kind of wind turbine generator.
Background technology
Wheel hub unsteady flow cabinet cabinet in the existing wind turbine generator is to divide cabinet to combine by three six prismatics, all be located in the cabinet because cabinet is installed connecting hole, so when cabinet is winched to the fastening locking nut of wheel hub cast top, must open the cabinet door, and filled electronics, electric components in the cabinet of this moment, therefore, must be very careful during lifting; And, according to specification requirement, also must apply suitable moment to locking nut, operate very difficult.If the loosening or stripped thread phenomenon at the cabinet generation connecting bolt of wind field operation when in time not handling, tends to cause cabinet to occur tearing, cause electronics in the cabinet, electric components to damage.Maintenance must be operated in the aerial narrow space of height again, and extremely inconvenient, labour intensity is big, the maintenance cost height.
The utility model content
The purpose of this utility model provides a kind of simple in structure, and is easy for installation, safe and reliable, and maintenance is easy, the wheel hub unsteady flow cabinet cabinet that maintenance cost is low.
The purpose of this utility model is achieved through the following technical solutions: it comprises 3 similar fan-shaped branch cabinets in cross section, each minute, the bottom of cabinet bulk excircle was equipped with the circular arc flange, be distributed with unthreaded hole on each circular arc flange, be beneficial to be connected with the stud of wheel hub cast top, fasten as one by bolt assembly between each minute cabinet, a side relative with the exterior arc surface of minute cabinet is provided with otic placode on the branch cabinet, otic placode is provided with through hole, and each otic placode through hole is corresponding with three connecting holes on the slip ring bearing of wheel on the hub casts.
The utility model is simple in structure, and is easy for installation, safe and reliable, maintenance easily, maintenance cost is low, cabinet is installed connecting hole and all is located at outside the cabinet, when implementing lifting, tighten the screws or beat moment and all needn't open the cabinet door; Lifting or when safeguarding, all electronics in the cabinet, electric components are unaffected.Need only three three connecting holes on the lifting bolts aligning wheel hub slip ring bearing, the hole on the circular arc flange gets final product the stud at aligned wheels hub casts top.
Description of drawings
Fig. 1 is the utility model one embodiment wheel hub unsteady flow cabinet cabinet and wheel hub slip ring bearing assembly structure schematic diagram;
Fig. 2 is a wheel hub unsteady flow cabinet cabinet hoisted in position structural representation shown in Figure 1.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
With reference to accompanying drawing, present embodiment comprises 3 similar fan-shaped branch cabinets 7 in cross section, each minute, cabinet 7 bottom excircles were equipped with circular arc flange 12, be distributed with 5 unthreaded holes 8 on each circular arc flange 12, be beneficial to be connected with the stud of taking turns hub casts 4 tops, fasten as one by bolt assembly 5 between each minute cabinet 7, a side relative with the exterior arc surface of minute cabinet is provided with otic placode 11 on the branch cabinet 7, otic placode 11 is provided with through hole, and each otic placode through hole is corresponding with three connecting holes on the slip ring bearing 6 of wheel on the hub casts 4.
During lifting, earlier lifting bolt 9 is screwed into the otic placode through hole, suspension ring by lifting bolt 9 heads are sling the wheel hub unsteady flow cabinet cabinet of the utility model, three connecting holes on the slip ring bearing 6 on the lifting bolt 9 aligned wheels hub casts 4, at this moment, the stud at wheel hub casts 4 tops is aimed at the unthreaded hole 8 on the circular arc flange 12 just, operating personnel can realize taking turns being connected between hub casts 4 tops and the wheel hub unsteady flow cabinet cabinet circular arc flange at this moment fast, withdraw from lifting bolt 9, change bolt assembly and tighten, and all bolts are applied definite value moment, easy and simple to handle.
