Description
Technical field
The utility model relates to the loose feeding system gravity dragline type limit switch protector of a kind of converter; be adapted to especially the high temperature locations such as the loose blanking system that feeds intake of converter steelmaking, oxygen battle sight be spacing, belong to the loose feeding system limit-switch device technical field of metallurgy industry converter.
Background technology
Metallurgy industry, the loose feeding system of converter is the important procedure in steel smelting procedure, in smelting process, will, by adding lime, quartzite, agglomerate, magnetic concentration etc., remove sulphur and other impurity in molten iron, completes the smelting of different steel grades.The loose feeding system of converter is made up of three parts: be topmost 1, feed bin; 2, middle portion is for weighing blanking system; 3, bottom for gathering feeding system.What weigh blanking system and gather that feeding system all adopts is to control quadrant valve to open and close to realize and feed intake, and approach switch is installed on quadrant valve, is used for showing working order and the interlocked control of feed valves.In actual application, the hot gas rising along feed opening when smelting can often burn out approach switch and cable, and the expense of not only taking a lot of work material, also often can delay production.
Utility model content
The utility model object is to provide the loose feeding system gravity dragline type limit switch protector of a kind of converter, can effectively prevent that approach switch and cable from burning out, and solves the problem existing in background technology.
The technical solution of the utility model is:
The loose feeding system gravity dragline type limit switch protector of a kind of converter, comprise retaining screw, fixed pulley, cable wire, fixed support, spacing stone roller, approach switch, spacing stone roller conduit, iron ball and quadrant valve, one end of cable wire is fixed on the top of quadrant valve one side by retaining screw, the below of quadrant valve opposite side is provided with fixed pulley, cable wire passes from fixed pulley, the other end of cable wire connects iron ball, cable wire between fixed pulley and iron ball is provided with spacing stone roller, spacing stone roller is fixed on fixed support, spacing stone roller is located in spacing stone roller conduit, spacing stone roller conduit is provided with, lower two approach switchs.
Adopt the utility model, in the time that quadrant valve is opened, cable wire is stretched and drives spacing stone roller to promote, and while opening completely, spacing stone roller just in time triggers the approach switch (reaching position) of top; When quadrant valve is closed, the iron ball of cable wire below drives spacing stone roller to decline, and while closing completely, spacing stone roller triggers the approach switch (pass puts in place) of below.
The beneficial effects of the utility model are: can effectively allow approach switch stow away from heat, avoid often burning out, impact is produced, and have simple in structurely, are convenient to make the feature of convenient operating maintenance.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
In figure: retaining screw 1, fixed pulley 2, cable wire 3, fixed support 4, spacing stone roller 5, approach switch 6, spacing stone roller conduit 7, iron ball 8, quadrant valve 9.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
With reference to accompanying drawing 1, the loose feeding system gravity dragline type limit switch protector of a kind of converter, comprise retaining screw 1, fixed pulley 2, cable wire 3, fixed support 4, spacing stone roller 5, approach switch 6, spacing stone roller conduit 7, iron ball 8 and quadrant valve 9, one end of cable wire 3 is fixed on the top of quadrant valve 9 one sides by retaining screw 1, the below of quadrant valve 9 opposite sides is provided with fixed pulley 2, cable wire 3 passes from fixed pulley 2, the other end of cable wire 3 connects iron ball 8, cable wire between fixed pulley 2 and iron ball 8 is provided with spacing stone roller 5, spacing stone roller 5 is apart from iron ball 400mm, spacing stone roller 5 is fixed on fixed support 4, spacing stone roller 5 is located in spacing stone roller conduit 7, switch quadrant valve 9 drives spacing stone roller 5 to move up and down in spacing stone roller conduit 7, on spacing stone roller conduit 7, open, lower two holes, two approach switchs are installed.
In the time that quadrant valve 9 is opened, cable wire 3 is stretched and drives spacing stone roller 5 to promote, and while opening completely, spacing stone roller 5 just in time triggers the approach switch (reaching position) of top; When quadrant valve 9 is closed, the iron ball 8 of cable wire 3 belows drives spacing stone roller 5 to decline, and while closing completely, spacing stone roller 5 triggers the approach switch (pass puts in place) of below.
