Abstract
The invention relates to a screw-nut transmission device for a steel gate. The screw-nut transmission device comprises a screw; a sleeve sleeves the screw; the lower end of the screw is provided with a connecting rod; a nut is arranged in an inner cavity at the upper end of the connecting rod and sleeves the lower end of the screw; the outer circle of the upper end of the connecting rod is provided with a flange; the upper end of the flange is provided with a sealing gasket; the upper end of the sealing gasket is provided with a pressing plate and is connected with the flange through a bolt. The screw-nut transmission device is simple in structure, scum in water can be prevented from entering the screw-nut transmission device, the seizure between the screw and the nut can be avoided, and the steel gate can be normally opened and closed.
Description
Technical field
The present invention relates to the screw nut driving device that a kind of steel gate is used, belong to hydraulic engineering equipment technical field.
Background technology
Steel gate is normally used for crossing in the local hydraulic structure of opening and closing the bascule at the mouth of a river, is generally used for for dock pump house, and switching motion is more frequent.Traditional dark bar steel gate is that nut is set in upper end in steel gate door body, headstock gear screw mandrel active section is just forming screw nut driving pair with nut engagement bottom, when opening to rise, steel gate door body opens or descending when closed, screw rod transmission and nut is motionless, thereby make steel gate door body increase or decline, realizing opening and closing movement.Due to screw mandrel and nut transmission, work under water, lubrication oil is easily lost in water, and apply oil is very inconvenient under water.The loss of lubrication oil, has caused the too early wearing and tearing of screw mandrel and nut transmission, and in water, scum silica frost also easily penetrates in nut transmission simultaneously, thereby causes killing between screw mandrel and nut transmission, and steel gate cannot be opened.
Summary of the invention
For above-mentioned defect, the object of the present invention is to provide a kind of simple in structure, can anti-sealing in scum silica frost enter screw nut driving device, guarantee not kill between screw mandrel and nut the screw nut driving device that a kind of steel gate of phenomenon is used.
The technical solution adopted in the present invention is for this reason: comprise screw mandrel, described screw mandrel is provided with sleeve outward, screw mandrel lower end is provided with connecting rod, connecting rod upper end inner chamber is provided with nut sleeve and is connected on screw mandrel lower end, connecting rod upper end cylindrical is provided with flange, flange upper end is provided with sealing mat, and sealing mat upper end is provided with pressing plate and is connected with flange by bolt.
Described connecting rod inner chamber is provided with baffle plate and is positioned at nut lower end, and baffle plate is provided with through hole and passes for screw mandrel.
Advantage of the present invention is: the present invention is simple in structure, can anti-sealing in scum silica frost enter in screw nut driving device, guaranteed that screw mandrel and nut can not kill phenomenon, thereby guaranteed that steel gate can normally open and close.
