The countershaft overhanging place of the utility model outside the fan shroud at described motor top is designed with the handwheel for hand turning, and handwheel guard shield is housed outside handwheel; Described jiggering clutch guard and handwheel guard shield are all provided with compression type and often drive position limit switch, the two is connected in series, and only has pressure simultaneously could connect circuit, to ensure safety.
Described jiggering clutch is the tooth-like clutch structure of self-detaching, refers to Chinese patent 201310349627.3.
Described speed reducer bottom surface and clutch guard bottom surface are positioned in same plane, and are all arranged on above TRT turbine-shaft bearing housing.
Described small gear is together with by hinged bolts nut, half-clutch structure connects firmly with slip, can axially move on speed reducer output shaft under the effect of clutch operating mechanism, its displacement distance limited by operating device, but ensures to engage completely with the gearwheel be arranged on turbine-shaft and throw off completely.
Described gearwheel hot jacket clamping method is arranged on TRT set main shaft, and the teeth directional of the side that is meshed with small gear is chamfering structure, and during to ensure to need jiggering, small gear can be meshed with gearwheel easily under operating device effect.
Working principle of the present utility model is as follows:
When not needing jiggering, small gear and gearwheel are in the state of throwing off completely.When unit start needs jiggering, first guarantee handwheel guard shield correctly install and clamping motor guard shield on position limit switch, then clutch operating mechanism is pulled, the half-clutch structure of slip is made to move to the position of engaging completely with fixing half-clutch structure, now small gear also engages completely with gearwheel, position limit switch on the clutch guard of operating device pressure simultaneously, then open disk vehicle motor, unit can jiggering success.When set main shaft rotating speed increases to over jiggering output speed, under the effect of automatically throwing off tooth-like clutch structure, small gear will be separated with gearwheel automatically, and the position limit switch simultaneously on clutch guard unclamps, and jiggering circuit disconnects automatically.
The beneficial effects of the utility model are as follows:
The utility model proposes a kind of parallel-axis type barring gear for TRT jiggering, solve the problem that TRT device can not arrange coaxial-type jiggering.This barring gear is simple and compact for structure simultaneously, can realize automatic disengagement, convenient operating maintenance, safe and reliable.

Embodiment
The utility model is described further below in conjunction with embodiment's (accompanying drawing).
As shown in Figure 1, TRT electric barring equipment of the present utility model is arranged on above TRT turbine-shaft bearing housing, and it comprises the power plant be made up of motor 1, speed reducer 2, the jiggering clutch driven by power plant; Described jiggering clutch is comprised the fixing half-clutch structure 7 be fixed on described speed reducer 2 output shaft, is arranged in the mode be slidably matched on speed reducer 2 output shaft and the half-clutch structure of slip 6 be meshed with fixing half-clutch structure 7 and the small gear 5 be fixed together with half-clutch structure 6 of sliding by link; (torque that speed reducer exports is delivered to small gear, gearwheel by jiggering clutch to there is corresponding outer gearing relation between described small gear 5 and the gearwheel 3 being packed on TRT turbine-shaft 4 outside jiggering clutch guard 12, and pass to set main shaft, thus realize jiggering function), the operating device 11 doing to move axially for the half-clutch structure 6 that controls to slide is arranged on described jiggering clutch guard 12.
The countershaft overhanging place of the utility model outside the fan shroud at described motor top is designed with the handwheel 13 for hand turning, and handwheel guard shield is housed outside handwheel; Described jiggering clutch guard and handwheel guard shield are all provided with compression type and often drive position limit switch 10,14, the two is connected in series, and only has pressure simultaneously could connect circuit, to ensure safety.
Described jiggering clutch is the tooth-like clutch structure of self-detaching, refers to Chinese patent 201310349627.3.
Described speed reducer bottom surface and clutch guard bottom surface are positioned in same plane, and are all arranged on above TRT turbine-shaft bearing housing.
Described small gear 5 is together with by hinged bolts nut, half-clutch structure 6 connects firmly with slip, can axially move on speed reducer output shaft under the effect of clutch operating mechanism 11, its displacement distance limited by operating device 11, but ensures to engage completely with the gearwheel 3 be arranged on turbine-shaft 4 and throw off completely.
Described gearwheel 3 hot jacket clamping method is arranged on TRT set main shaft, and the teeth directional of the side that is meshed with small gear 5 is chamfering structure, and during to ensure to need jiggering, small gear 5 can be meshed with gearwheel 3 easily under operating device 11 acts on.
More specifically, position limit switch 14 on the position limit switch 10 of clutch guard described in the utility model and handwheel guard shield is compression type and often drives position limit switch, the two connected in electrical series, pressure is simultaneously only had to connect circuit, namely only have handwheel guard shield to be in place, simultaneously tooth-like clutch structure engagement, small gear engages with gearwheel, circuit could be connected, to ensure safety.After jiggering success, clutch is thrown off automatically, and the position limit switch simultaneously on guard shield unclamps, and circuit disconnects automatically.
When TRT unit starting needs jiggering, pull operating device 11, rotate handwheel 13 simultaneously, tooth-like clutch structure is engaged completely, and at this moment small gear 5 also engages completely with gearwheel 3, then installs handwheel guard shield, clamping stroke switch, then open disk vehicle motor.After TRT unit is successfully opened, tooth-like clutch structure is thrown off automatically, and jiggering circuit also disconnects automatically, and small gear 5 is separated with gearwheel 3 simultaneously.
