Abstract
The utility model relates to a lid structure of a ship ballast well. The structure comprises a ballast well mouth, a flange plate, a blind plate and a filter cylinder, wherein the step flange plate is welded on the inner wall of the ballast well mouth, and the step flange plate is composed of an annular upper shim plate and an annular lower shim plate which are concentrically welded from top to bottom; the blind plate is arranged on the upper end face of the upper shim plate, through holes corresponding to the upper shim plate are drilled in the blind plate, the lower ends of bolts A penetrate through the through holes of the blind plate and then are in threaded connection with the upper shim plate, and the upper end of each bolt A is in threaded connection with a locking nut A; and the filter cylinder is arranged on the upper end face of the lower shim plate, through holes corresponding to the lower shim plate are drilled in the filter cylinder, the lower ends of bolts B penetrate through the through holes of the filter cylinder and then are in threaded connection with the lower shim plate, and the upper end of each bolt B is in threaded connection with a locking nut B. When a crew needs to enter the ballast well for maintaining, the locking nuts A on the blind plate and the locking nuts B on the filter cylinder are rotated, and the crew can get in and out of the ballast well; and the structure is convenient to disassemble.
Description
Technical field
The utility model relates to a kind of ballast for cruising well well lid structure, particularly a kind of ballast for cruising well well lid structure of convenient disassembly.
Background technology
When ballast tank is ship in ballast, be used for holding the general name in the cabin of ballast, ballast is the weight that makes mooring stability be convenient to operate, and is generally seawater.In the ballast well of ballast tank filter cylinder is housed, the foreign material of filtered water when being used for introducing seawater, it mainly opens the ballast well head on the tank top plate of ballast tank, filter cylinder is fixed in the well head, and covers sealing through cover plate.It exists shortcoming to be: the crewman gets into when keeping in repair in the double bottom through ballast well opening, need unclamp the tie bolt of filter cylinder and tank top plate, and bolt employing countersunk head screw can not be opened easily sometimes.
Summary of the invention
The technical matters that the utility model will solve provides a kind of ballast for cruising well well lid structure of convenient disassembly.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of ballast for cruising well well lid structure; Comprise ballast well well head, flange, blind plate and filter cylinder; Said ballast well well head inwall is welded with stepped flange, and said stepped flange is by the annular upper padding plate and the annular lower bolster of welding constitute with one heart from top to bottom; Its innovative point is: be evenly distributed with some tapped bore on the said upper padding plate; The upper padding plate upper surface is provided with blind plate; Be drilled with on the blind plate and the cooresponding through hole of upper padding plate, the lower end of each double-screw bolt A is threaded with upper padding plate after passing the through hole of blind plate, the upper end of the double-screw bolt A jam nut A that is threaded; Be evenly distributed with some tapped bore on the said lower bolster; The lower bolster upper surface is provided with filter cylinder; Be drilled with on the filter cylinder and the cooresponding through hole of lower bolster, the lower end of each double-screw bolt B is threaded with lower bolster after passing the through hole of filter cylinder, the upper end of the double-screw bolt B jam nut B that is threaded.
The advantage of the utility model is: during the ballast tank ballast; The upper padding plate of stepped flange and the welding of ballast well well head inwall; Filter cylinder is fixed on the lower bolster of flange, and between each backing plate of flange and blind plate, filter cylinder, fills up waterproof grommet, guarantees the watertight of ballast well.Need the crewman to get into when keeping in repair in the ballast well, jam nut A on the rotation blind plate and the jam nut B on the filter cylinder can hold the crewman and pass in and out ballast well, convenient disassembly.
Description of drawings
Fig. 1 is the utility model ballast for cruising well well lid architecture scheme drawing.
The specific embodiment
As shown in Figure 1, comprise ballast well well head 1, flange, blind plate 2 and filter cylinder 3, ballast well well head 1 inwall is welded with stepped flange, and stepped flange is made up of with annular lower bolster 5 the annular upper padding plate 4 of welding with one heart from top to bottom; Be evenly distributed with some tapped bore on the upper padding plate 4; Upper padding plate 4 upper surfaces are provided with blind plate 2; Be drilled with on the blind plate 2 and upper padding plate 4 cooresponding through holes, the lower end of each double-screw bolt A6 is threaded with upper padding plate 4 after passing the through hole of blind plate 2, the upper end of the double-screw bolt A6 jam nut A7 that is threaded.
Be evenly distributed with some tapped bore on the lower bolster 5; Lower bolster 5 upper surfaces are provided with filter cylinder 3; Be drilled with on the filter cylinder 3 and lower bolster 5 cooresponding through holes, the lower end of each double-screw bolt B8 is threaded with lower bolster 5 after passing the through hole of filter cylinder 3, the upper end of the double-screw bolt B8 jam nut B9 that is threaded.
During the ballast tank ballast, upper padding plate of stepped flange 4 and the welding of ballast well well head 1 inwall, filter cylinder 3 is fixed on the lower bolster 5 of flange, and between each backing plate of flange and blind plate 2, filter cylinder 3, fills up waterproof grommet, the watertight of assurance ballast well.Need the crewman to get into when keeping in repair in the ballast well, jam nut A7 on the rotation blind plate 2 and the jam nut B9 on the filter cylinder 3 can hold the crewman and pass in and out ballast well, convenient disassembly.
