Description
Technical field
The utility model relates to a kind of novel headstock gear that is applied in the Hydraulic and Hydro-Power Engineering, especially a kind of side-pull type fixation winding headstock gear.
Background technology
At present, the layout of Hydraulic and Hydro-Power Engineering sluice is because of being subjected to the restriction of water level, hinge layout etc., and more employing Vertical Lift plane gate adds the arrangement of Straight pull fixation winding headstock gear.When the river middle and lower reaches are built sluice, the highest flood discharge water level and normal pool level differ bigger, cause between inspection platform and the end bank clear height bigger; When simultaneously the gate height was big, inspection platform was also bigger with the clear height that opens and closes between the platform, thereby caused that civilwork engineering quantity is big, difficulty of construction is big, long in time limit, whole shock resistance is poor and a series of problems such as difficulty are overhauled comparatively in the headstock gear installation.
Summary of the invention
The utility model is to overcome above-mentioned problems of the prior art, and a kind of side-pull type fixation winding headstock gear is provided, and vertical-lift gate and headstock gear are staggered on the plane on arranging, makes inspection platform and keying platform on same elevation.Not only can avoid high framed bent building is set, make dam facing arrange that neat and artistic, installation and Maintenance and Repair are convenient, and minimizing civilwork engineering quantity and difficulty of construction that can be bigger, the reduction of erection time, generating electricity in advance for the power station creates conditions.
The technical solution adopted in the utility model is: it includes motor, brake, reducer, pinion shaft, reel, running block, stabilizer device, combination wire rope and frame, described brake is arranged between motor and the reducer, motor is connected with input shaft of speed reducer, the output shaft of reducer is connected with pinion shaft, the two ends that it is characterized in that described pinion shaft and reel are provided with helical gear and are meshing with each other the transmission of composition open type; Described running block adopts layout, and is arranged in the outside of reel and frame; Described reel conspires to create the duplex reel system with combination wire rope, running block, stabilizer device.
The open type transmission of described pinion shaft and described reel is the transmission of herringbone shunting.
Described reel and combination wire rope, running block, stabilizer device composition multiplying power are two duplex reel system.
During electric motor starting, the running block of headstock gear moves up or down, and reaches the purpose that opens and closes gate.
The beneficial effects of the utility model are: 1) needn't design the high framed bent of concrete and open and close platform on arranging, reduce civilwork engineering quantity, reduce the civil engineering difficulty, shorten the duration, increase the resistance to overturning and the shock resistance of hydraulic structure.2) gate and headstock gear stagger on the plane on arranging, their installation, debugging can be carried out synchronously, have shortened metal construction installation period.3) the dam facing layout is neat and artistic, and installation and Maintenance and Repair are convenient.4) since civil engineering and metal construction installation period obvious shortening is arranged, for advantage has been created in the engineering generating that is completed ahead of schedule.5) the running block plane is adopted and is arranged to have less gauge, is convenient to the gate close arrangement; Closely spaced assembly pulley rope stretching design, even under water at the complete slack rope state of wire rope, also can guarantee wire rope at the movable pulley place disorder cable not, thereby guaranteed the operational reliability of headstock gear.6) the herringbone shunting is adopted in the open type transmission of headstock gear, and the two pairs of helical gears are by axial thrust load balance voluntarily, uniform distribution transfer torque, make the headstock gear stable drive, effectively reduce noise and impact force.7) to adopt multiplying power be two duplex reel system to headstock gear, each stressed wire rope branch, and all the changed course by pulley becomes a whole rope, need not carry out the stretch-draw adjustment, therefore, reel is not had special making requirement, installs and also adjusts simple and fast relatively.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: as accompanying drawing 1,2,3, shown in 4, the utility model side-pull type fixation winding headstock gear, it includes motor 1, brake 2, reducer 3, pinion shaft 4, reel 5, running block 6, stabilizer device 7, combination wire rope 8 and frame 9, described brake 2 is arranged between motor 1 and the reducer 3, motor 1 is connected with the power shaft 3a of reducer 3, the output shaft 3b of reducer 3 is connected with pinion shaft 4, it is characterized in that the described pinion shaft 4 and the two ends of reel 5 are provided with helical gear and are meshing with each other the transmission of composition open type; Described running block 6 adopts layout, and is arranged in the outside of reel 5 and frame 9; Described reel 5 conspires to create the duplex reel system with combination wire rope 8, running block 6, stabilizer device 7.
Described pinion shaft 4 is the transmission of herringbone shunting with the open type transmission of described reel 5.
Described reel 5 and combination wire rope 8, running block 6, stabilizer device 7 composition multiplying powers are two duplex reel system.
The method of operation of this headstock gear is: motor 1 starts, transfer a torque to reducer 3, by exporting pinion shaft 4 to after reducer 3 decelerations, the open type helical gear that pinion shaft 4 is arranged by herringbone passes to reel 5 with moment of torsion, drive reel 5 rotations, thereby make the duplex reel system work that reel 5, running block 6, stabilizer device 7 and combination wire rope 8 are formed, reach the purpose that opens and closes gate.When gate arrived assigned address, motor 1 stopped, and brakes by brake 2.
