Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments.
Fig. 1 is the front view of this blower fan generator set wheel hub system lifting upset fitting device;
Fig. 2 is the birds-eye view of the lifting upset fitting device among Fig. 1;
Fig. 3 is the running condition scheme drawing of this blower fan generator set wheel hub system lifting upset fitting device.
The specific embodiment
This blower fan generator set wheel hub system lifting upset fitting device (hereinafter to be referred as fitting device) is mainly used in the lifting upset operation of large fan generator set wheel hub system.As depicted in figs. 1 and 2, this fitting device is a triangular supports utilizing channel-section steel, steel plate to constitute.Channel-section steel GB/T707-198816 * 1720 millimeter are used as crossbeam 1, and channel-section steel GB/T707-198816 * 555 millimeter are used as longeron 4, and channel-section steel GB/T707-198816 * 3000 millimeter are used as cant beam 6.Each root beam in crossbeam, longeron and the cant beam all uses the channel-section steel of two same sizes to dock, and the steel plate of therebetween 12 millimeters thick increases bonding area when making the butt joint of two steel plates.Wherein, crossbeam 1, cant beam 6 and longeron 4 all are that channel-section steel is welded Face to face, are used to strengthen frock rigidity and intensity.
Below the two ends of crossbeam 1 length direction, be welded with 305 * 305 * 20 millimeters of two block plates as connecting panel 2, be used to connect fitting device and pitch variable bearings inner ring.The back will be described connection mode in detail.The arranged outside of each connecting panel 2 has three mounting holes 21.The described outside is meant, be installed to fitting device on the pitch variable bearings after, in an outer side (that is the outside of the above-below direction among Fig. 3) of the connecting panel on the diametric(al) of pitch variable bearings 2.
One end of cant beam 6 is connected with crossbeam 1, and is provided with attached plate 9 in the junction, plays booster action.The other end of cant beam 6, promptly the end away from crossbeam 1 is provided with boatswain chair 8.The size of boatswain chair 8 is 340 * 200 * 20 millimeters, and middle position is provided with lifting hole(eyelet), articulates suspension hook when being used to lift by crane.Boatswain chair 8 is welded between two channel-section steels of cant beam 6.
For guaranteeing support intensity, the channel-section steel that fitting device uses can adopt GB/T707-198816 type channel-section steel.All be furnished with clamping plate 9,10,11 on each channel-section steel and be used to increase bonding area assurance weld strength, crossbeam and longeron, crossbeam and cant beam, junction between longeron and the cant beam, three places all are provided with attached plate and are used for deep beam and longeron, being connected between crossbeam and the cant beam, longeron and cant beam, increase bonding area.
Introduce the use installing condition of this wheel hub system lifting upset fitting device below.
Weldering plate that thickness is 12mm as shown in Figure 3, be intended to increase the bonding area of two channel-section steels butt joint, strengthen weld strength), six mounting holes 21 of two connecting panels 2 are aimed at six inner ring blade bolt mounting holes of the inner ring of pitch variable bearings, the crossbeam 1 of fitting device is striden diameter to be installed on the inner ring of pitch variable bearings, and in the streamlined reefer housing sleeve, cant beam 6 then extends to outside the streamlined reefer housing sleeve and surpasses the position on the top of wheel hub.By inner ring blade bolt mounting holes, utilize bolt, two connecting panels 2 are fixed to bearing inner ring with three mounting holes respectively.At this, bearing arrangement adopts double row same diameter ball formula turntable bearing, and its anti-shearing crooking ability is very strong, so can not cause bearing deformation.The pitch circle diameter of pitch variable bearings blade bolt mounting holes is 1800 millimeters, and the vertical distance in adjacent two holes is 6.08 millimeters, 33 millimeters of the diameters in hole.When being connected with bearing, the diameter of interstitial hole is 1800 millimeters in the upset frock, with the vertical distance in adjacent two holes be 6 millimeters, the diameter in hole is 35 millimeters, is slightly larger than 33 millimeters in bearing blade installation hole, guarantees that connecting panel energy and bearing make things convenient for be connected.Guarantee to guarantee the support rigidity and the intensity of frock under the slick and sly full situation at weld seam.80 millimeters of lifting hole(eyelet) opening diameters on the cant beam 6 of fitting device away from being subjected to force direction, can strengthen lifting intensity.And lifting hole(eyelet) adopts the excessive fillet of 100 millimeters of diameters to be convenient to the suspension hook upset.Cant beam 6 length adopt 3000 millimeters, extend outside the wheel hub, and make lifting hole(eyelet) be positioned at position above the top of wheel hub.Like this, can make lifting rope and suspension hook be higher than hub height, when wheel hub overturns 90 when spending, lifting rope is unlikely to run into streamlined reefer housing; The length of longeron 6 adopts 555 millimeters, makes support stretch out the streamlined reefer housing sleeve; The length of crossbeam 1 adopts 1720 millimeters pitch circle diameters that are slightly smaller than bearing inner ring, can guarantee that the distance of two interstitial holes on the connecting panel 2 is 1800 millimeters when itself and connecting panel 2 are welded, and is convenient to be connected with bearing.The unified reasonable structural steel of this welding performance of Q235A that adopts of this frock material reduces stress concentration; Certain anti-corrosion treatment is carried out on the surface, can long-term use.The wheel hub system used channel-section steel of lifting frock is GB/T707-198816, and clamping plate and attached plate all are to play the increase bonding area, and it is used to strengthen frock intensity and rigidity.
More than blower fan generator set wheel hub provided by the utility model system lifting upset fitting device is had been described in detail.For one of ordinary skill in the art, any conspicuous change of under the prerequisite that does not deviate from the utility model connotation it being done all will constitute to the utility model infringement of patent right, with corresponding legal responsibilities.
