Abstract
The present invention relates to a kind of novel dark lever brake door.Including doorframe and door body, described door body is arranged in doorframe, described doorframe is arranged over fixed mount, described door body upper end is provided with hanger, described hanger is connected with sleeve lower end, a screw mandrel it 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 block, described bearing block is arranged on fixed mount, Step Shaft upper end is provided with bearing cap, described bearing cap is fixedly connected with the bearing seat by bolt, described bearing cap and bearing block respectively and are provided with bearing between the upper and lower end face of Step Shaft, described sleeve upper end is internally installed 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.Present configuration is simple, by screw mandrel is built in sleeve pipe, it is to avoid lubricating oil is lost in water, also prevent during in water, scum silica frost enters screw mandrel and nut transmission simultaneously, reduce the phenomenon killed between screw mandrel and nut transmission, substantially prolongs service life.
Description
Technical field
The present invention relates to a kind of novel dark lever brake door, belong to water channel board plug type gate valve technical field in hydraulic engineering.
Background technology
Steel-slag sand is typically to be used for opening and closing the bascule crossing the mouth of a river in the hydraulic structure of local, is generally used for for dock pump house, and 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, headstock gear screw mandrel active section just becomes feed screw nut's transmission with nut engaging in bottom, when steel-slag sand door body open rise open or descending Guan Bi time, screw rod transmission and nut is motionless, so that steel-slag sand door body rises or falls, it is achieved opening and closing movement.Owing to screw mandrel works under water with nut transmission, lubricating oil is easily lost in water, and it is very inconvenient to add lubricating oil under water, the loss of lubricating oil, causes the premature abrasion of screw mandrel and nut transmission, during in water, scum silica frost also easily infiltrates into nut transmission, causing killing between screw mandrel and nut transmission, gate cannot be opened, and service life is short, needing to increase screw mandrel aisle during casting door body, complex process manufacturing cost is high.
Summary of the invention
For drawbacks described above, it is an object of the invention to provide a kind of simple in construction, lubricating status is good, it is to avoid kill phenomenon between screw mandrel and nut transmission, easy to assembly, lubrication a kind of novel dark lever brake door.
For this technical solution adopted in the present invention it is:
Including doorframe and door body, described door body is arranged in doorframe, described doorframe is arranged over fixed mount, described door body upper end is provided with hanger, described hanger is connected with sleeve lower end, a screw mandrel it 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 block, described bearing block is arranged on fixed mount, Step Shaft upper end is provided with bearing cap, described bearing cap is fixedly connected with the bearing seat by bolt, described bearing cap and bearing block respectively and are provided with bearing between the upper and lower end face of Step Shaft, described sleeve upper end is internally installed 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 cap 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 connected by bolt and screw mandrel lower end are fixing.
The invention have the advantage that
Present configuration is simple, by screw mandrel is built in sleeve pipe, it is to avoid lubricating oil is lost in water, also prevent during in water, scum silica frost enters screw mandrel and nut transmission simultaneously, reduce the phenomenon killed between screw mandrel and nut transmission, substantially prolongs service life.
