Description
Technical field
The utility model relates to the dark bar steel of a kind of Wet-dry gate, belongs to water channel board plug type gate valve technical field in the hydraulic engineering.
Background technology
The steel gate normally is used for crossing in the local hydraulic structure of opening and closing the bascule at the mouth of a river, the general dock pump house that is used for, and switching motion is more frequent.Traditional dark bar steel gate is that nut is set in upper end in the steel gate door body, headstock gear screw mandrel active section is just forming feed screw nut's transmission with the nut engagement bottom, when opening to rise, steel gate door body opens or descending when closed, screw mandrel transmission and nut is motionless, thereby steel gate door body is risen or decline, realize opening and closing movement.Because screw mandrel and nut transmission are worked under water, lubrication oil is lost in the water easily, 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 scum silica frost also penetrates in the nut transmission easily in the water simultaneously, thereby causes killing between screw mandrel and the nut transmission, makes the steel gate to open.
The utility model content
At above-mentioned defective, the purpose of this utility model be to provide a kind of simple in structure, lubricating status good, avoided killing phenomenon between screw mandrel and the nut transmission the dark bar steel of a kind of Wet-dry gate that has prolonged application life greatly.
The technical scheme that adopts of the utility model is for this reason: comprise lock groove doorframe, the door body, double-hanging point headstock gear and two service bridges, described double-hanging point headstock gear is installed on two service bridges, described each service bridge lower end is provided with sleeve, be provided with screw mandrel in the sleeve, the screw mandrel upper end is passed service bridge and is connected with the main shaft of headstock gear, the screw mandrel lower end is provided with connecting rod, connecting rod upper end inner chamber is provided with the nut that is socketed in the screw mandrel lower end, connecting rod upper end cylindrical is provided with flange, the flange upper end is provided with sealing mat, the sealing mat upper end is provided with pressing plate and is connected with flange by bolt, and the connecting rod lower end is connected with the door body, and the door body is positioned at lock groove doorframe.
Described sealing mat diameter is greater than the sleeve inner diameter.
Described double-hanging point headstock gear is two suspension centre manual and electric double-purpose headstock gears.
The described door body left and right sides is provided with roller, and described roller is positioned at lock groove doorframe, and described lock groove doorframe bottom is provided with sealing rubber pad.
Described door body upper end is provided with two hangers, and described hanger is connected with connecting rod by bearing pin.
Described connecting rod central exterior surface is provided with the spindle guide tube, and described spindle guide tube is fixed by the spindle guide tube frame that is installed on the lock groove doorframe.
The utility model has the advantages that: the utility model is simple in structure, by screw mandrel and nut transmission are placed in the space of sealing, avoided lubrication oil to be lost in the water, stoped also simultaneously that scum silica frost enters into screw mandrel and nut transmission in the water, screw mandrel and nut transmission can not killed phenomenon thereby reduced between screw mandrel and the nut transmission by seawater corrosion yet.
