The specific embodiment

Below in conjunction with accompanying drawing one embodiment of the present of invention are further described:

Shown in the accompanying drawing, the present invention is used for the turning device of crane drum speed reducer general assembly, mainly is comprised of power and transmission device, a seat assembly, clamping device and chassis vehicle.Wherein: chassis vehicle mainly is comprised of vehicle frame 7, four wheels 6 and two directive wheels 8; Wherein vehicle frame 7 is the monolithic construction part that is become by Plate Welding, and four wheels 6 are installed in the two bottom sides of vehicle frame 7 by the wheel carrier symmetry, and wheel 6 can rotate holding up the plane; Two directive wheels 8 are installed in the longitudinal axis position of vehicle frame 7 bottoms by its wheel carrier, but rotate on the directive wheel horizontal plane.Prop up seat assembly and mainly formed by left support abutment 5, right support abutment 9, be located at respectively on the chassis vehicle; Left support abutment 5 and right support abutment 9 are welded by plurality of steel plates, and the upper face of its underpart and vehicle frame 7 welds together, and power and drive unit are located on the left support abutment 5; Clamping device is located between left support abutment 5 and the right support abutment 9.Power and transmission device mainly are comprised of piston type pneumatic motor 1, decelerator 2, driving gear 3; Wherein decelerator 2 is fixed by screws on the reducer stent 4, driving gear 3 is connected by flat key with decelerator 2 output shafts after passing through hole on left support abutment 5 wooden partitions, driving gear 3 be meshed by the driven gear 16 of bearing sliding bearing on left support abutment 5 inner side ends.Clamping device is comprised of crank 10, screw rod 11, bearing support 12, right anchor clamps 14, left anchor clamps 15, driven gear 16, and driven gear 16 is by the top of bearing sliding bearing at left support abutment 5; Left anchor clamps 15 are fixed on the right side of driven gear 16.Bearing support 12 by the bearing sliding bearing on the top of right support abutment 9, with left anchor clamps 15 on same axis, be located at 2 backplates 13 with driven gear 16 rotations between driven gear 16 and the bearing support 12.The central shaft of bearing support 12 is to being processed with tapped through hole, and screw rod 11 passes the screwed hole of centre that passes again bearing support 12 behind the through hole of right support abutment 9, and the inner end of screw rod 11 is connected with the right anchor clamps 14 corresponding with left anchor clamps 15, and the outer end is fixedly connected with crank 10.
