Description
Technical field
The utility model relates to a kind of novel dark lever brake door, belongs to water channel board plug type gate valve technical field in hydraulic engineering.
Background technology
Steel-slag sand is normally used for opening and closing the bascule crossing the mouth of a river in the hydraulic structure of local, and be generally used for for dock pump house, switching motion is more frequent.Traditional dark bar steel-slag sand is that nut is set in upper end in steel-slag sand door body, to form screw nut driving secondary just engaging with nut bottom for headstock gear screw mandrel active section, when steel-slag sand door body open rise open or descending closed time, screw rod transmission and nut is motionless, thus make steel-slag sand door body increase or decline, realize opening and closing movement.Because 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, causes the premature abrasion of screw mandrel and nut transmission, in water, scum silica frost also easily penetrates in nut transmission, cause killing between screw mandrel and nut transmission, gate cannot be opened, and application life is short, need to increase screw mandrel aisle during casting door body, complex process manufacturing cost is high.
Utility model content
For above-mentioned defect, it is simple that the purpose of this utility model is to provide a kind of structure, and lubricating status is good, avoids between screw mandrel and nut transmission and kills phenomenon, easy to assembly, lubrication a kind of novel dark lever brake door easily.
The technical scheme that the utility model adopts for this reason is:
Comprise doorframe and door body, described door body is arranged in doorframe, fixed mount is provided with above described doorframe, described door body upper end is provided with hanger, described hanger is connected with an its lower end, a screw mandrel is socketed with in described sleeve pipe, described screw mandrel upper end is provided with Step Shaft, Step Shaft lower end is provided with bearing support, described bearing support is arranged on fixed mount, Step Shaft upper end is provided with bearing cover, described bearing cover is fixedly connected with bearing support by bolt, described bearing cover and bearing support are provided with bearing respectively and between the upper and lower end face of Step Shaft, described sleeve upper end inside is provided with keying nut, described keying nut sleeve is connected on screw mandrel, described screw mandrel lower end is provided with baffle plate, the upper end of described screw mandrel is connected with headstock gear.
Further, described bearing cover is provided with oil filler, and described oil filler is provided with plug.
Further, described its lower end is enclosed construction.
Further, described baffle plate is fixedly connected with screw mandrel lower end by bolt.
The utility model has the advantages that:
The utility model structure is simple, by screw mandrel is built in sleeve pipe, avoids lubrication oil and be lost in water, also prevent scum silica frost in water to enter in screw mandrel and nut transmission simultaneously, reduce the phenomenon of killing between screw mandrel and nut transmission, substantially prolongs application life.
