Description
Technical field
The utility model relates to the syndeton of a kind of box type electrical machine fan guard and support.
Background technology
The fan guard of absolutely empty cooling box type electrical machine is arranged on base outer, the below of cooler.When running for avoiding motor, fan guard change in location causes fan and fan guard or suction nozzle to rub the fan caused mutually to rupture, and fan guard needs reliably and support, cooler are fixed together.Fixing means conventional in prior art is fixed for adopting double threaded screw, end face of machine base is processed with screwed hole, fan guard has respective through hole, end face of machine base is processed with screwed hole, double threaded screw one end is fixed in end face of machine base, the other end penetrates in fan guard, and adopts two nuts to be clamped by fan guard side plate, thus completes the fixing of fan guard.This syndeton, because double threaded screw one end hold-down nut is in fan guard, is installed inconvenient.Palpus first double threaded screw during provided with fan cover, then provided with fan cover, rear installation cooler, assembly sequency is fixed, cannot according to production site, and material etc. adjust operation flexibly, causes production efficiency lower.When maintenance motor needs to dismantle fan guard, first must dismantle cooler, then dismantle fan guard, installation and maintenance are inconvenient.
Utility model content
The utility model provides the syndeton of a kind of box type electrical machine fan guard and support, and structure is simple, convenient for installation and maintenance, can improve motor production efficiency.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: the syndeton of a kind of box type electrical machine fan guard and support, motor fan housing, on the side plate of support, four Angle Position is welded with support bar, support bar is welded with fixed head, fixed head is processed with inverted U-shaped gap; When fan guard is installed, each double threaded screw one end is fixed on the screwed hole of end face of machine base, and the other end stretches in the inverted U-shaped gap of fixed head, and fan guard is fixed on electric machine stand outside by the nut tightening the fixed head left and right sides.
It is parallel with support side plate and towards on the facade outside motor that fixed head is welded on support bar.
The one side that fixed head is parallel with fan guard side plate is processed with inverted U-shaped gap, and gap runs through the lower limb of fixed head.
After fan guard is installed, there is certain distance at inverted U-shaped gap top to stud upper surface, and this distance to be greater than on end shield plane to the distance of cooler lower edge.
The length of double threaded screw is slightly shorter than the vertical range of end face of machine base and fan guard interior plate.
The utility model structure is simple, practical function, and convenient for installation and maintenance, raises labour efficiency, and also improves motor production efficiency simultaneously.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is right view of the present utility model.
Embodiment
Embodiment: as shown in Figure 1, 2, the syndeton of a kind of box type electrical machine fan guard and support, comprise support 1, cooling water pipe 2, fan, fan guard, the fan guard of motor is welded with support bar 4 on four Angle Position on the side plate of support 1, support bar 4 is welded with fixed head 5, fixed head 5 is processed with inverted U-shaped gap 5-1; When fan guard is installed, each double threaded screw one end is fixed on the screwed hole of end face of machine base, and the other end stretches in the inverted U-shaped gap 5-1 of fixed head, and fan guard is fixed on electric machine stand 1 outside by the nut 6 tightening fixed head 5 left and right sides, and nut 6 place is provided with pad 7.It is parallel with support 1 side plate and towards on the facade outside motor that fixed head 5 is welded on support bar 4.The one side that fixed head 5 is parallel with fan guard side plate is processed with inverted U-shaped gap 5-1, and gap runs through the lower limb of fixed head 5.After fan guard is installed, there is certain distance at inverted U-shaped gap 5-1 top to stud 3 upper surface, and this distance to be greater than on end shield plane to the distance of cooler 2 lower edge.The length of double threaded screw 3 is slightly shorter than the vertical range of support 1 end face and fan guard interior plate.
End face of machine base of the present utility model is processed with screwed hole near the corner of support side plate, fan guard is welded with support bar on the side plate of support, the welding position of support bar correspond to the position of end face of machine base screwed hole, and the other end is parallel with support side plate and be welded with fixed head on the facade outside motor.The one side that fixed head is parallel with fan guard side plate is processed with inverted U-shaped gap.When fan guard is installed, each double threaded screw one end is fixed in end face of machine base, the other end is with nuts and washers and stretch into inverted U-shaped gap, afterbody installs a bolt and a packing ring again, and firm for fan guard can be fixed on electric machine stand outside by the nut screwing clamping of the fixed head left and right sides.Screw rod and all fastening nuts all can operate outside support and outside fan guard, and outside motor, easy for installation, and can raise labour efficiency.
Support bar one end of the present utility model is welded on fan guard side plate, it is parallel with support side plate and towards on the facade outside motor that fixed head is welded on support bar, operating personnel can make spanner up and down without spatial limitation when being fastened and fixed the nut of plate both sides, easy for installation, and can raise labour efficiency.
The side plate lower edge of the surrounding of cooler of the present utility model is generally higher than the mounting plane of fan guard and cooler.In conventional mounting structure, support assorted hole on double threaded screw and fan guard is circular hole, because the height of fan guard whereabouts is lower than the distance of plane on end shield to cooler lower edge during dismounting fan guard, dismounting fan guard is caused to disassemble cooler, time-consuming.A kind of box type electrical machine fan guard of this utility patent and the syndeton of support, the one side that fixed head is parallel with fan guard side plate is processed with inverted U-shaped gap, gap runs through the lower limb of fixed head, after fan guard is installed, inverted U-shaped gap top to be greater than on end shield plane to the distance of cooler lower edge to the distance of stud upper surface.Fan guard and screw rod can not be dismantled during user's field stripping fan guard, only the nut of the fixed head left and right sides is unclamped, and the nut on right side, packing ring are taken off, the connecting bolt of fan guard and cooler is pulled down, fan guard can fall naturally, and fan guard can axially be dismantled down.When a kind of box type electrical machine fan guard of this utility patent and the syndeton of support can make user's site examining and repairing motor disassembling fan guard, do not need to dismantle cooler, convenient for users with maintenance.
The length of double threaded screw of the present utility model is slightly shorter than the vertical range of end face of machine base and fan guard interior plate, and stator has inverted U-shaped gap, can make double threaded screw after cooler, support, fan guard are installed together, by being screwed in the screwed hole of end face of machine base below inverted U-shaped gap.Thus the erection sequence of cooler, fan guard, double threaded screw is changed arbitrarily, and can according to production site, materials etc. adjust operation flexibly, improve motor production efficiency.
