The connecting structure between the rapid gate hydraulic headstock gear and the sealing gate groove comprises a cylinder, a cylinder support and the sealing gate groove, wherein the cylinder support is horizontally arranged on a concrete platform arranged above the sealing gate groove and fixedly connected with foundation bolt embedded parts though a gasket and a connecting plate, the upper portion of the cylinder is fixedly connected with the cylinder support through a cylinder flange, the lower portion of the cylinder penetrates downward through a sealing cover plate of the sealing gate groove, the peripheral surface of a cylinder lower cover arranged above the sealing cover plate is upward and sequentially sleeved with a sealing pressing cover and a binding nut in a threaded mode, a sealing ring is arranged between contact surfaces of the sealing cover plate and the sealing pressing cover, and an O-shaped sealing ring is arranged between an inner periphery surface of the sealing pressing cover and the peripheral surface of a lower end cover of the cylinder. The connecting structure between the rapid gate hydraulic headstock gear and the sealing gate groove has the advantages of decreasing weight of equipment, reducing technical difficulty of manufacturing and processing, benefiting installation of the equipment and eliminating deviation, and facilitating operation of the equipment in a later period due to the fact that adjustment is achieved by means of the rotation of the sealing pressing cover.
Description
Technical field
The present invention relates to quick gate hydraulic headstock gear, especially relate to the syndeton of quick gate hydraulic headstock gear and sealed gate groove.
Background technology
Irrigation in hydraulic engineering, draining and water supply pumping plant or small hydropower station are provided with Emergency Gate, and when the unit of pumping plant had an accident, the stop gate of pumping plant water outlet side setting should cut off current protection unit.At the pumping plant normal operation period, stop gate is suspended on the top, aperture; When flying the accident such as ease when the water wheels unit in power station, require power station stop gate Rapid door closer in 2 minutes, the safety of protection water wheels unit and factory building, gate is in fully open position at ordinary times.Stop gate is suspended on the runner top of water pump or the hydraulic turbine usually, and the hydraulic hoist of controlling stop gate directly is connected with gate, is convenient to realize the Rapid door closer action.because the position of runner is lower, the platform of the gate slot top installation hydraulic switch machine equipment of stop gate is positioned under pumping plant or power station ordinary water level, therefore, for preventing that hydraulic hoist is immersed in water, need whole gate slot is totally-enclosed, conventional frame mode is: the seal cover board of the frame of hydraulic hoist and gate slot is united two into one be arranged to integral door scouring machine shelf structure, be integrated by Bolt Connection with the water shutoff seat board at gate slot top, hydraulic hoist is fixed on the flange of integral door scouring machine top of the trellis, piston rod passes integral door scouring machine frame and is connected with gate, integral door scouring machine frame and water shutoff seat board, be provided with rubber seal between integral door scouring machine frame and hydraulic cylinder piston rod, realize the integral sealing of gate slot.It is to be delivered to the water shutoff seat board by integral door scouring machine frame that the hydraulic hoist of this form of structure opens a force-summing device deadweight, causes integral door scouring machine shelf structure complicated, heavy.Integral door scouring machine frame adopts the rear whole processing of welding, and manufacturing process is complicated, machining accuracy is high, increase the difficulty of transporting.When mounted simultaneously, to elevation and the more difficult adjustment of position deviation that forms in the civil engineering process, the operation of equipment later stage is had a negative impact.
Summary of the invention
The object of the invention is to provide the syndeton of a kind of quick gate hydraulic headstock gear and sealed gate groove.
For achieving the above object, the present invention takes following technical proposals:
The syndeton of quick gate hydraulic headstock gear of the present invention and sealed gate groove comprises oil cylinder, cylinder bracket, sealed gate groove; Described cylinder bracket is horizontally set on the concrete platform of sealed gate groove top, and is fixedly connected with stone bolt embedded part in concrete platform by pad, junction plate; Described oil cylinder top is fixedly connected with cylinder bracket by the cylinder body flange; The oil cylinder lower cover is passed down through the seal cover board of sealed gate groove, be positioned at above described seal cover board oil cylinder lower cover outer peripheral face upwards successively thread bush gland, binding nut are housed; Be provided with sealing ring between seal cover board and gland contact surface; Be provided with " O " shape sealing ring between gland inner peripheral surface and oil cylinder bottom end cover outer peripheral face.
Described sealing ring is placed in the annular groove that is opened in the gland soffit, and described " O " shape sealing ring is placed in the annular groove that is opened in described oil cylinder bottom end cover outer peripheral face.
The invention has the advantages that existing integral door scouring machine shelf structure is decomposed into two of the seal cover board of sealed gate groove and cylinder brackets, change simultaneously the outside syndeton with the sealed gate groove of oil cylinder.Therefore, during work, quick gate hydraulic headstock gear is directly delivered to load on the concrete platform basis by cylinder bracket, has alleviated weight of equipment, has reduced manufacturing and processing technology difficulty.Simultaneously, rotate adjustment by gland, be convenient to the installation of equipment and eliminate deviation, be conducive to the operation of equipment later stage.
