Description
Technical field
It the utility model is related to a kind of gate of Hydraulic and Hydro-Power Engineering, and in particular to a kind of screw rod hydraulic pressure dual drive opens and closes
Machine.
Background technology
In some large hydraulic engineerings, often it is related to open-close sluice gate, wherein it is wider with vertical winding type open-close sluice gate application,
Vertical winding type open-close sluice gate has the advantages of simple in construction, manufacturing cost is low and service life is long, but vertical elevator at present
Formula open-close sluice gate can only realize opening and closing two states, and water-carrying capacity can not be adjusted, and largely limit volume
The promotion and application of formula open-close sluice gate are raised, and vertical winding type open-close sluice gate can only be by manually grasping using Mechanical Driven at present
Make or driven using motor, manual operation wastes time and energy, and motor driving cost of investment is high.
Utility model content
The utility model is in view of the deficienciess of the prior art, provide a kind of screw rod hydraulic pressure dual drive headstock gear.
The utility model includes drive mechanism and gate, and drive mechanism is connected by pull bar with gate, and gate locating is in door
In groove, it is that drive mechanism includes screw rod and oil cylinder to solve technical scheme used by its technical problem, screw front end and lower section
The piston rod of oil cylinder is connected, and piston rod bottom is connected by spring with pull bar, and oil cylinder sets oil inlet and oil-out, screw rod sidepiece
Lock screw is set.
Above-mentioned gate slot inside top sets guide pads.
Above-mentioned screw tip sets handle.
The utility model both can drive pull bar to move by screw rod, can also be realized and drawn by oil pressure distribution station by oil pump
Bar moves, and realizes the mechanical-hydraulic dual drive operator scheme of gate, improves the operation automation of gate, realize gate liter
The controllability of drop, there is the advantages of rational in infrastructure, easy to use and reliable and stable.
Brief description of the drawings
The utility model is further illustrated with specific embodiment below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model drive mechanism.
1 drive mechanism, 2 pull bars, 3 gates, 4 gate slotes, 5 guide pads, 11 screw rods, 12 oil cylinders, 13 piston rods, 14 bullets in figure
Spring, 15 oil inlets, 16 oil-outs, 17 lock screws, 18 handles.
Embodiment
As depicted in figs. 1 and 2：A kind of screw rod hydraulic pressure dual drive headstock gear, including drive mechanism 1 and gate 3, driving machine
Structure 1 is connected by pull bar 2 with gate 3, and gate 3 is arranged in gate slot 4, and gate slot inside top sets guide pads 5.Drive mechanism 1
Including screw rod 11 and oil cylinder 12, the front end of screw rod 11 is connected with the piston rod 13 of the oil cylinder 12 of lower section, and the bottom of piston rod 13 passes through bullet
Spring 14 is connected with pull bar 2, and oil cylinder 12 sets oil inlet 15 and oil-out 16, and the sidepiece of screw rod 11 sets lock screw 17, screw rod 11
Top sets handle 18.
The utility model both can drive pull bar to move by screw rod, can also be realized and drawn by oil pressure distribution station by oil pump
Bar moves, and realizes the mechanical-hydraulic dual drive operator scheme of gate, improves the operation automation of gate, realize gate liter
The controllability of drop, there is the advantages of rational in infrastructure, easy to use and reliable and stable.
