Description
Technical field
The utility model relates to water conservancy equipment technical field, especially a kind of steel arch-gate.
Background technique
Steel arch-gate is widely used in hydraulic and hydroelectric engineering, with simple, the required gate pier of structure height and thickness compared with
It is small, without influence water flow dynamic gate slot, hoisting capacity it is small, easy to operate the features such as, traditional steel arch-gate generally passes through lock
The open and close that move up and down to realize gate of the door in dam body track groove are kept away in track groove after a protracted use
Unavoidably there is the accumulation of silt, a degree of influence will certainly be caused on the open and close of steel arch-gate.
Utility model content
For above situation, for the defect for overcoming the prior art, the purpose of the utility model is just to provide a kind of without logical
Cross the steel arch-gate that the mode that track and track groove cooperate realizes gate opening and closing.
Its solution is a kind of steel arch-gate, including dam body, the first fixed base, the second fixed base, the first fixed base
In the opposite side of dam body, the second fixed base is located at the top between dam body and the first fixed base, and the top of dam body is hinged with arc
Gate, the medial surface of gate are fixed with bracket, and bracket is hinged with first connecting rod, and first connecting rod free end is connected with the liquid of hydraulic cylinder
Compression bar and second connecting rod, first connecting rod free end, hydraulic stem, second connecting rod form compound hinges, hydraulic cylinder and the second fixed base
Hingedly, the free end of second connecting rod and the first fixed base are hinged.
Preferably, when closing gate, first connecting rod and second connecting rod are conllinear.
Preferably, it is fixed with convex block on gate lower outside face, there is groove corresponding with convex block on dam body.
Preferably, bracket is located at the middle part of gate medial surface.
The beneficial effects of the utility model are: the contraction of hydraulic pressure bar of hydraulic cylinder, drives the free end of gate to rotate, makes gate
It opens, then the hydraulic stem of hydraulic cylinder stretches out, and drives the free end of gate to rotate, makes closing gate.The opening and closing of gate
It is easy to operate, and the open and close of gate are without track groove, avoid gate due in track groove silt too much can not
The such case opened or closed.
Detailed description of the invention
Fig. 1 is structural schematic diagram when the utility model steel arch-gate is opened.
Fig. 2 is structural schematic diagram when the utility model steel arch-gate is closed.
Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
It is provided by Fig. 1 and Fig. 2, a kind of steel arch-gate, including dam body 1, the first fixed fixed base 7 of base 9, second is described
First fixed base 9 is located at the top between dam body 1 and the first fixed base 9, the dam body in the opposite side of dam body 1, the second fixed base 7
1 top is hinged with the gate 2 of arc, and lateral surface and the dam body 1 of gate 2 fit closely, and enables the completely cut off water of gate 2
Stream, the medial surface of gate 2 are fixed with bracket 3, and bracket 3 is hinged with first connecting rod 4, and 4 free end of first connecting rod is connected with hydraulic cylinder 6
Hydraulic stem 5 and second connecting rod 8,4 free end of first connecting rod, hydraulic stem 5, second connecting rod 8 form compound hinges, hydraulic cylinder 6 with
Second fixed base 7 is hinged, and the free end of second connecting rod 8 and the first fixed base 9 are hinged.
When gate 2 is closed, first connecting rod 4 and second connecting rod 8 are conllinear, in this way when water impact gate 2, first connecting rod
4 and second connecting rod 8 impact force is stated can fastly pass to the first fixed base 9, to improve the reliability of arc cylinder gate 2.
It is fixed with convex block 10 on the 2 lower outside face of gate, there is groove corresponding with convex block 10 on dam body 1
11, the connection of gate 2 and dam body 1 can be made relatively reliable in this way.
Bracket 3 is located at the middle part of 2 medial surface of gate.
The use of the use of the new type is described further in conjunction with Fig. 1 and Fig. 2, the use of the new type when in use: when need
When gate 2 being wanted to open, the hydraulic stem 5 of hydraulic cylinder 6 is shunk, and so that first connecting rod 4 and second connecting rod 8 is generated linkage, and then make first
Connecting rod 4, second connecting rod 8, hydraulic stem 5 do clockwise circular arc as the center of circle using the hinge joint of the first fixed base 9 and second connecting rod 8 and transport
Dynamic, first connecting rod 4 drives bracket 3 to move, and bracket 3 is made to do circular arc fortune counterclockwise with the hinge joint center of circle of gate 2 and dam body 1
Dynamic, when hydraulic stem 5 is in a horizontal position, hydraulic stem 5 stops shrinking, at this point, hydraulic stem 5 vertically with first connecting rod 4, gate 2
Fully open, when need gate 2 close when, hydraulic stem 5 stretch out hydraulic cylinder 6, make first connecting rod 4, second connecting rod 8, hydraulic stem 5 with
The hinge joint of first fixed base 9 and second connecting rod 8 is that circular motion counterclockwise is done in the center of circle, and first connecting rod 4 drives bracket 3 to transport
It is dynamic, so that bracket 3 is done clockwise circular motion with the hinge joint center of circle of gate 2 and dam body 1, when first connecting rod 4 and second connect
When bar 8 is conllinear, gate 2 is completely closed, and hydraulic stem 5 stops stretching out hydraulic cylinder 6 at this time.
Embodiment described above is not defined the scope of the utility model, is not departing from the utility model design
Under the premise of design, the various changes and improvements that technical staff described in this field makes the technical solution of the utility model,
It should be included in the protection scope of claims determination of the utility model.
