Abstract
The utility model discloses an oxygen lance winding steel wire rope groove-skipping prevention device for a converter, which includes an oxygen lance winding steel wire rope wound on a wire cable winding drum, wherein the oxygen lance winding steel wire rope is wound around a tension pulley; a rotating shaft of the tension pulley and a fixed pulley are connected with a balancing weight through a tension steel wire rope; a limit switch is installed on the falling path of the balancing weight; and the limit switch is connected with a control main engine of the converter. In the utility model, the looseness of the oxygen lance winding steel wire rope can be timely discovered by sensing the falling position of the balancing weight, and trouble shooting can be performed timely, so that the normal production can be guaranteed.
Description
Technical field
The utility model relates to a kind of converter oxygen gun hoisting rope groove separation preventing device.
Background technology
Oxygen blowing device is one of key processing equipment of top-blown oxygen converter.It accomplishes the work that in converter, blows oxygen.Oxygen blowing device is made up of oxygen rifle (claiming oxygen lance again), oxygen lance lifting device and oxygen rifle swivel arrangement three parts.During blowing, send in the burner hearth by the lifting device drive, on the certain altitude of metal pool surface, oxygen is being sprayed to liquid metal, to realize the smelting reaction of metal pool with the oxygen rifle of supporting pipeline to link to each other in the factory building.During blow off, the oxygen rifle drive to be risen by lifting device, cuts off oxygen during to certain altitude automatically, and after the oxygen rifle was extracted out in the stove, converter can be carried out other operation.Existing oxygen lance lifting equipment design behaviour in service is following: reel relies on three pulleys and a hoisting rope to connect with oxygen rifle column; And oxygen rifle column and oxygen rifle counterweight connect (conducting oneself with dignity about 9.5 tons) with the counterweight wireline, and when the driven by motor step-down gear rotated, the elevator reel that connects with step-down gear is rotation rotation thereupon also; After the reel rotation; The length of the hoisting rope that connects with tackleblock on the oxygen lance lifting device can change, and in conjunction with oxygen rifle counterweight, the oxygen lance lifting device is realized rising, down maneuver; And the oxygen rifle is fixed on the oxygen rifle transverse arm, also accomplishes rising, down maneuver; Under the prerequisite of hoist brake and spacing control, the oxygen rifle can be parked on the position of smelting technology requirement, realizes converter smelting.Slagging scorification is serious on oxygen gun body; Or rifle body deflection, and spacing up and down when malfunctioning, the oxygen rifle can be parked in nitrogen envelope ring (the oxygen rifle inserts the petticoat pipe mouth) or other possibly influence on the obstruction object of its motion; Even the situation of noting abnormalities; Stop the action of oxygen rifle immediately, hoisting rope also the groove phenomenon can occur taking off in the short period of time, and is difficult for finding.The accident generation frequency is about 6 times/month.Accident can cause steel wire stranded, distortion, clot after taking place, and the hoisting rope life cycle is shortened, in case and the hoisting rope fracture, can cause the oxygen rifle to weigh down the stove accident, there is big production safety hidden danger.
Summary of the invention
The purpose of the utility model is to provide a kind of converter oxygen gun hoisting rope groove separation preventing device, can in time find the loosening situation of oxygen rifle hoisting rope through the position, whereabouts of perception balancing weight, in time fixes a breakdown, and guarantees to produce and normally carries out.
The purpose of the utility model is to realize like this; A kind of converter oxygen gun hoisting rope groove separation preventing device; Be included in the oxygen rifle hoisting rope of reeling on the cable drum, this oxygen rifle hoisting rope is walked around from a tension pulley block, and the rotating shaft of tension pulley block is connecting a balancing weight through tensioning wireline and fixed pulley; A limit switch is installed on the descent path of balancing weight, and limit switch links to each other with the converter main control system.
The utility model can in time be found the loosening situation of oxygen rifle hoisting rope through the position, whereabouts of perception balancing weight, in time fixes a breakdown, and guarantees to produce and normally carries out.
Description of drawings
To combine accompanying drawing that the utility model is done further detailed explanation below.
Fig. 1 is the main TV structure synoptic diagram of the utility model.
Embodiment
A kind of converter oxygen gun hoisting rope groove separation preventing device; As shown in Figure 1; Be included in the oxygen rifle hoisting rope 8 of reeling on the cable drum 5, this oxygen rifle hoisting rope 8 is walked around from a tension pulley block 1, and the rotating shaft of tension pulley block 1 is connecting a balancing weight 3 through tensioning wireline 2 and fixed pulley; A limit switch 4 is installed on the descent path of balancing weight 3, and limit switch links to each other with the converter main control system.This limit switch 4 is wired travel switch or is wireless electric spacing safety device.When the utility model used, in oxygen rifle lifting process, motor 6 drove cable drum 5 through step-down gear 7 and discharges hoisting rope 8; When hoisting rope 8 meet come off or oxygen rifle jam after when being in relaxed state; Tension weight piece 3 falls voluntarily, and contacts electric spacing safety device, and the signal sender is to mainframe program; Can eject the warning picture at once on the operation room main control system screen; There are abnormal conditions (taking off groove or oxygen rifle jam) in prompting oxygen rifle hoisting rope, notifies producers' blowing out to check, avoids the generation of Serious Accident.
Claims (2)
1. converter oxygen gun hoisting rope groove separation preventing device; Be included in the oxygen rifle hoisting rope of reeling on the cable drum; It is characterized in that: this oxygen rifle hoisting rope is walked around from a tension pulley block; The rotating shaft of tension pulley block is connecting a balancing weight through tensioning wireline and fixed pulley, and a limit switch is installed on the descent path of balancing weight, and limit switch links to each other with the converter main control system.
