Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, interlocking drive unit comprises a buncher 15, and it is fixed on support 25 by bolt 21 and packing ring 22.Buncher has 3 output shafts, and wherein the output shaft of motor afterbody and shaft coupling 11 are fixed together by back-up ring 13 and screw 14.Pneumatic motor 1 is fixed on motor bracket 26 by bolt 2, nut 3 and packing ring 4, the bottom of pneumatic clutch 8 is fixed on the output shaft of pneumatic motor 1 by screw 9 and back-up ring 10 simultaneously, block 5 is fixed on motor bracket 26 by bolt 6 and packing ring 7, be used for preventing the rotation of pneumatic clutch 8, the top of pneumatic clutch 8 is fixed on shaft coupling 11 by screw 12 simultaneously.
On another output shaft of buncher 15, be fixed together by packing ring 18 and bolt 19 with handwheel 16, handle 17 is fixed on handwheel 16 by thread connection, and axle sleeve 20 is used for adjusting the position of handwheel 16 on reducing motor output shaft.
As shown in Figure 2, buncher 15 also has an output shaft and torque limiter 34 to be fixed together by baffle plate 36, bolt 37 and packing ring 38, and axle sleeve 35 is used for adjusting the position of torque limiter 34 on output shaft.Photoelectricity approach switch 39 is fixed on support 40, and support 40 is fixed on support 42 by bolt 41 simultaneously, and support 42 is fixed on support 25 by bolt 43 and packing ring 44.
In the present embodiment, buncher can be selected the product of German SEW-EURODRIVE group company, and buncher model is S87VZ21DV100L4/2WE.When this class buncher is normally worked, three output shafts rotate simultaneously, and one of them output shaft drives boiler tube to rotate by chain gear, when power-off, can pass through to rotate one of two other output shaft, and then drive boiler tube to be rotated further.
Support 25 tops by bolt 23 and nut 24 be connected with fixed support 30, bottom is connected with fixed support 30 by bearing pin 29, by setting nut 24, whole drive unit can be around bearing pin 29 rotations, change the width between centers size of buncher 15 output shafts and boiler tube 33 axis, thereby play the effect of tensioner chain 31.
Under nominal situation, interlocking drive unit drives sprocket wheel 32 rotations on boiler tube 33 by chain 31.When the rising suddenly of boiler tube load torque is transshipped over the set(ting)value of torque limiter 34, the structure disengagement automatically that torque limiter 34 is own, dallies buncher 15 output shafts, thereby protects boiler tube 33 not by physical damage.Photoelectricity approach switch 39 captures overload signal simultaneously, and sends automatic control system to, and robot control system(RCS) is automatically cut off buncher 15 power supplys and sends sound and light alarm according to program setting.For guaranteeing the normal work of interlocking drive unit under overload operating mode, answer the required load torque of computing equipment, thereby select suitable torque limiter 34 models.
