Regarding to the issue above, the utility model provides a kind of power plant heavy type gate lifting device, its small volume, structure letter
It is single, can effectively reduce equipment cost.
A kind of power plant's heavy type gate lifting device, it is characterised in that：It includes support, and the top surface of the support is provided with tiltedly
Gear turbine worm reducer, the helical gear turbine worm reducer has two parallel output shafts, described in one of them
Output shaft is connected by shaft coupling with one end of a power transmission shaft, another described output shaft by torque force limiting device and another
One end connection of power transmission shaft, two other ends of the power transmission shaft are respectively by shaft coupling and the input shaft of turbine screw lift
Connection, two turbine screw lifts are arranged on the support；Micro limit switch is arranged on the support, and institute
The disengaging that micro limit switch senses the torque force limiting device is stated, when the torque force limiting device departs from, the microstroke is opened
Pass sends control signal and controls the helical gear turbine worm reducer to be stopped.
Further, drive shaft protection cover is provided with the outside of the power transmission shaft, the drive shaft protection cover is arranged on described
On support.
Further, switch bracket is fixed with the support, the micro limit switch is arranged on the switch bracket
On.
The beneficial effects of the utility model are：
1st, the utility model drives two drive axis, two power transmission shaft difference by helical gear turbine worm reducer
Two turbine rotations of turbine screw lift are driven, and then motion lifts heavy gate jack-up upwards to make screw mandrel, is lifted
Gate weight up to more than 25t, and lifting device simple structure, small volume, significantly reduce equipment cost；
2nd, the utility model is provided with micro limit switch and torque force limiting device, after gate is lifted in place, torque force limiting device
The moment of torsion for being born departs from the moment of torsion for exceeding its setting, and now micro limit switch senses the de- of torque force limiting device
Control signal control helical gear turbine worm reducer will be sent after to be stopped, overload so can be effectively prevented, and be realized

Specific embodiment
See Fig. 1-2, a kind of power plant's heavy type gate lifting device of the present utility model, it includes support 1, the top surface of support 1
Helical gear turbine worm reducer 2 is installed, helical gear turbine worm reducer 2 has two parallel output shafts, and two defeated
Shaft respectively positioned at helical gear turbine worm reducer 2 both sides and be coaxially disposed, one of output shaft by shaft coupling 3 with
One one end connection of power transmission shaft 4, another output shaft is connected by torque force limiting device 5 with one end of another power transmission shaft 4, and two
The other end of individual power transmission shaft 4 is connected by shaft coupling 3 with the input shaft of turbine screw lift 6 respectively, two turbine screw mandrel liters
Drop machine 6 is arranged on support 1；Switch bracket 7 is fixed with support 1, micro limit switch 8 is arranged on switch bracket 7, and micro-
Dynamic travel switch 8 senses the disengaging of torque force limiting device 5, and when torque force limiting device 5 departs from, micro limit switch 8 sends control letter
Number control helical gear turbine worm reducer 2 is stopped；The outside of power transmission shaft 4 is provided with drive shaft protection cover 9, power transmission shaft protection
Cover 9 is arranged on support 1.
Torque force limiting device 5 is the torque force limiting device with shaft coupling.
Preferably, the power of helical gear turbine worm reducer 2 is 0.37 kw, and speed is than being 389；Turbine screw lift 6
Speed than be 32, screw lead is 16m, maximum lift speed be 1.23mm/min.
Lifting process：
This lifting device is placed in gate lower section and the screw mandrel 6-1 of two turbine screw lifts 6 is withstood gate, started
Helical gear turbine worm reducer 2, it drives power transmission shaft 4 to rotate, and then drives the turbine rotation of turbine screw lift 6, makes
The screw mandrel 6-1 of turbine screw lift 6 rises, and the lifting of gate jack-up is lifted when in place, because helical gear turbine and worm slows down
Being rotated further for machine 2 can cause overload, and torque now has exceeded the torque that torque force limiting device 5 sets so that torque force limiting device 5
Depart from, the disengaging of torque force limiting device 5 has touched micro limit switch 8, micro limit switch 8 is sent control signal control
Helical gear turbine worm reducer 2 is stopped, and so as to prevent gate from continuing to rise, overload is played to this lifting device and gate
Protective effect, while also playing automatic shutdown effect, helical gear turbine worm reducer 2 is closed without artificial.
