Description
Technical field
The utility model belongs to converter annex, particularly relates to the safety guard of grate room before a kind of Converter.
Background technology
The converter that converter steelmaking workshop uses, different with the character of operation according to operation place, grate room after converter master control room, grate room, stokehold and stove is set before and after converter, STEELMAKING PRODUCTION whole process is controlled.Current, viewing window is established in grate room, stokehold, observes furnace cover lifting and oxygen rifle position etc., operator in grate room, stokehold at the hot metal charging that inclines, add steel scrap, thermometric sampling and slag tap and all want tilting converter fire door, carry out grate operation.Though the defect existed is that grate room, stokehold and converter mouth have certain skew span, but skew span is less, converter incline hot metal charging, add steel scrap, the time of falling stove, the situation that easy generation Injection In Molten Iron is quick-fried, the direct splash of molten iron is on the viewing window of grate room, stokehold, damage viewing window, and then threaten the personnel safety of stokehold grate in-house operation personnel, there is serious potential safety hazard.
Utility model content
In order to overcome the defect of prior art, the purpose of this utility model is to provide grate room aerodynamic slide rail safety guard before a kind of Converter, avoids stokehold to spray quick-fried damage viewing window, ensures operator's personnel safety, eliminate safe hidden trouble.
Aerodynamic slide rail safety guard in grate room before Converter, comprise grate room, stokehold, viewing window is established in grate room in stokehold, be characterized in that this device is made up of driving mechanism, guide rail and protective door, driving mechanism with cylinder and stay cord is located on grate room, establishes guide rail before viewing window, and protective door is installed in the guide groove of guide rail, stay cord is connected with protective door, and driving mechanism drives protective door to open and close along slide.
The utility model improves further, described driving mechanism is made up of cylinder, fixed pulley group, stay cord, running block and counterweight, cylinder is arranged at top, grate room, stokehold, the top edge setting tackleblock of grate room, stokehold, the line of centres of two fixed pulleys and grate room, stokehold top surface being parallel; Stay cord is by stay cord
and stay cord
composition, stay cord
one end connects counterweight, and the other end connects running block, and two travelling block are by stay cord
connect, stay cord
lower end connects protective door, and running block can reduce the weight of counterweight, avoids the counterweight using bulk.
The utility model improves further, described protective door is made up of framework, upper door-plate, lower door-plate and slide rail, upper door-plate, lower door-plate are made by steel plate, shape and the viewing window of steel framework adapt, and upper door-plate, are all placed in framework, and frame facet matches with guide rail, lower door-plate side vertical establishes slide rail, upper door-plate is placed on slide rail, and hanger is established, stay cord in upper door-plate upper surface
fasten through hanger.When pushing away before cylinder, counterweight drives stay cord
drop-down, protective door is closed; During cylinders retract, upper door-plate glides along guide groove, slide rail by deadweight, and upper door-plate is overlapping with lower door-plate, and whole protective door is opened, and does not stop the sight line of grate room, stokehold viewing window.
Compared with prior art, advantage is novel, and structure letter is gathered, rationally; This device makes full use of the space of grate room, stokehold, cylinder and counterweight are installed as propulsion source at furnace chamber top, realize closedown and the unlatching of protective door, and do not stop the sight line of grate room, stokehold viewing window, once stokehold spray is quick-fried, Injection In Molten Iron splashes on protective door, does not damage viewing window, avoid personal injury, ensure that converter is produced smoothly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of aerodynamic slide rail safety guard in grate room before Converter;
