Abstract
The utility model discloses a connecting structure of a rapid gate hydraulic hoist and a sealing gate groove. The connecting structure of the rapid gate hydraulic hoist and the sealing gate groove comprises an oil cylinder, an oil cylinder support and the sealing gate groove. The oil cylinder support is horizontally arranged on a concrete platform which is arranged above the sealing gate groove, and is fixedly connected with foundation bolt embedded parts in the concrete platform through a gasket and a connecting plate. The upper portion of the oil cylinder is fixedly connected with the oil cylinder support through a cylinder body flange. A lower cover of the oil cylinder downwards penetrates through a sealing covering plate of the sealing gate groove. A sealing gland and a binding nut are upwards sleeved on the outer circumference surface of the lower cover of the oil cylinder which is arranged above the sealing covering plate in a threaded mode in sequence. A seal ring is arranged between the contact surface of the sealing covering plate and the contact surface of the sealing gland. An O-shaped seal ring is arranged between the inner circumference surface of the sealing gland and the outer circumference surface of the lower end cover of the oil cylinder. The connecting structure of the rapid gate hydraulic hoist and the sealing gate groove has the advantages of reducing the weight of equipment, reducing difficulty of manufacture and a machining process, being beneficial to installation of the equipment and elimination of deviation due to the fact that adjustment is carried out through rotation of the sealing gland, and being beneficial to later-stage operation of the equipment.
Description
Technical field
The utility model relates to the stop gate hydraulic hoist, especially relates to the syndeton of stop gate hydraulic hoist and sealed gate groove.
Background technology
Irrigation in the 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 then is suspended on the top, aperture; When flying 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 the water pump or the hydraulic turbine usually, and the hydraulic hoist of controlling stop gate directly links to each other with gate, is convenient to realize the Rapid door closer action.Because the position of runner is lower, the platform that hydraulic hoist equipment is installed at the gate slot top of stop gate is positioned under pumping plant or the power station ordinary water level, therefore, for preventing that hydraulic hoist is immersed in the 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, with the water shutoff seat board at gate slot top be one by Bolt Connection, 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 links to each other with gate, integral door scouring machine frame and water shutoff seat board, be provided with rubber seal between integral door scouring machine frame and the 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 complexity, heaviness.The whole processing in integral door scouring machine frame employing welding back, the difficulty of manufacturing process's complexity, machining accuracy height, increase transportation.When mounted simultaneously, elevation and the difficult adjustment of position deviation to forming in the civil engineering process have a negative impact to the operation of equipment later stage.
Summary of the invention
The utility model purpose is to provide the syndeton of a kind of stop gate hydraulic hoist and sealed gate groove.
For achieving the above object, the utility model is taked following technical proposals:
The syndeton of stop gate hydraulic hoist described in the utility model 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 fixedlys connected with the stone bolt embedded part in the concrete platform by pad, junction plate; Fixedly connected with cylinder bracket by the cylinder body flange in described oil cylinder top; The oil cylinder lower cover is passed down through the seal cover board of sealed gate groove, be positioned at above the described seal cover board oil cylinder lower cover outer peripheral face upwards successively thread bush gland, binding nut are housed; Between seal cover board and gland contact surface, be provided with sealing ring; Between gland inner peripheral surface and oil cylinder bottom end cover outer peripheral face, be provided with " O " shape sealing ring.
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 utility model advantage is existing integral door scouring machine shelf structure is decomposed into two of the seal cover board of sealed gate groove and cylinder brackets, changes the outside syndeton with the sealed gate groove of oil cylinder simultaneously.Therefore, during work, the stop gate hydraulic hoist 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, adjust, be convenient to the installation of equipment and eliminate deviation, help the operation of equipment later stage by the gland rotation.
