Description
Technical field
The present invention relates to the steel-making converter smelting equipment, relate to the sublance system that supporting converter smelting uses in the steelshop, particularly a kind of anti-falling mechanism for sublance body.
Background technology
The sublance system of the interior supporting converter smelting use of steelshop at present, the overwhelming majority is an introducing equipment, the homemade autonomous innovation work of sublance system was at the early-stage in recent years.When unexpected fracture appears in the wireline that promotes the rifle body,, all do not consider the safeguard procedures of this respect in most projects for how preventing that sublance weightlessness from falling into converter.Though analyze from the safety coefficient of wireline and possibility aspect that this unforeseen circumstances occurs, the probability that the generation sublance falls is very little, but in case this accident takes place, consequence is hardly imaginable, serious situation may take place is, a large amount of water coolants can enter the accident of blasting in the high-temperature molten steel because of the damage of rifle body in the rifle body.Therefore, be necessary on physical construction, to consider to set up to weigh down the rifle safeguard procedures.
Summary of the invention
Task of the present invention provides a kind of anti-falling mechanism for sublance body, and it has solved when sublance weightlessness falls and cause taking place the problem of major accident into converter.
Technical solution of the present invention is as follows:
A kind of anti-falling mechanism for sublance body, it comprises sublance body, sublance lifting guide frame, be installed in the lift cart car body that can move up and down on the sublance lifting guide frame, and being installed in the lift cart guide deflection sheave that rolls along sublance lifting guide frame guide rail on the lift cart car body, it also comprises the pulley gear that is installed on the lift cart car body, anti-fall block, anti-fall spring, and anti-fall buffering collision block;
Described pulley gear is equipped with pulley bracket, pulley, pulley gear alignment pin and pulley gear backstop, pulley gear is connected with the lift cart car body by alignment pin, wireline is wrapped on the pulley and with lift cart and is connected, and pulley gear backstop is installed in bottom two sides of pulley bracket;
Described anti-fall block is installed in pulley gear near on the sublance lifting guide frame steel plate of riser guide one side;
One end of described anti-fall spring is fixedlyed connected with the lift cart car body, and the other end of anti-fall spring is fixedlyed connected with the pulley bracket bottom;
Described anti-fall buffering collision block is fixedly mounted on the pulley bracket.
Anti-falling mechanism for sublance body of the present invention has following advantage: design is succinct practical, low cost of manufacture, and stopping distance is short, impact is little, and safe reliability is good, is convenient to install, and is convenient to adjust the position of buffering collision block, and the maintenance of the equipment amount is little.
Description of drawings
Accompanying drawing is the structural representation of a kind of anti-falling mechanism for sublance body of the present invention.
Embodiment
Referring to accompanying drawing, a kind of anti-falling mechanism for sublance body of the present invention comprises sublance body 1, sublance lifting guide frame 2, be installed in the lift cart car body 3 that can move up and down on the sublance lifting guide frame 2, and be installed in the lift cart guide deflection sheave 4 that rolls along sublance lifting guide frame 2 guide rails on the lift cart car body 3.
Anti-falling mechanism for sublance body of the present invention also comprises the pulley gear 5 that is installed on the lift cart car body 3, several anti-fall blocks 6, anti-fall spring 7, and anti-fall buffering collision block 8.
Pulley gear 5 is equipped with pulley bracket 51, pulley together with pulley rotating shaft 52, pulley gear alignment pin 53 and pulley gear backstop 54.Pulley is installed on the pulley bracket 51 by pulley rotating shaft 52.Pulley gear 5 is connected with lift cart car body 3 by alignment pin 53.Wireline is wrapped on the pulley and with lift cart and is connected.Pulley gear backstop 54 is installed in bottom two sides of pulley bracket 51.
Several anti-fall blocks 6 are installed in pulley gear near on sublance lifting guide frame 2 steel plates of riser guide one side, install an anti-fall block 6 at a certain distance, constitute several anti-fall blocks that gather and arrange, forming several anti-fall blocks 6 thus respectively has the arrangement of spacing ground to be installed on the sublance lifting guide frame steel plate.Several anti-fall blocks 6 can be by welded and installed on sublance lifting guide frame 2 steel plates.
Anti-fall buffering collision block 8 is fixedly mounted on the pulley bracket 51.As shown in FIG., anti-fall buffering collision block 8 can be installed in the bottom of pulley bracket 51.This anti-fall buffering collision block 8 can be made by intensity height, material that plasticity is good, and the high-strength material that promptly has plastic property is made.Anti-fall buffering collision block 8 is minimum with the horizontal clearance of anti-fall block 6.
When lift cart carries out normal lifting work by being installed in wireline on the pulley, because the own wt of parts such as sublance body 1 and lift cart, make the upper surface of pulley gear backstop 54 be pressed on the respective frame lower surface of lift cart all the time, the pretension power deficiency of anti-fall spring 7 is so that the pulley gear generation is the swing of medullary ray with alignment pin 53, and equipment can normally stably move.
When in case the accident of wireline fracture suddenly takes place, sublance becomes complete runaway condition together with lift cart has lost pull of steel wire, generation is along the movement tendency of the downward freely falling body of guide rail, at this moment, anti-fall spring 7 can shrink moment, the pulling pulley gear rotates along alignment pin 53, the anti-fall buffering collision block 8 that is fixed on the pulley bracket 51 is pressed close to the riser guide side rapidly, because the guide rail total length is all according to certain interval anti-fall block 6 that gathered, anti-fall buffering collision block 8 can be blocked and make lift cart and sublance to stop to fall at once by anti-fall block 6.Because anti-fall buffering collision block 8 is minimum with the gap of anti-fall block 6 during normality, the pretension of anti-fall spring 7 is abundant, the time of response of the anti-fall buffering collision block 8 in weightless back is extremely lacked (about 0.12s), and the range of interior during this period of time sublance and lift cart freely falling body (wire cable rupture takes place when at full throttle 150m/min descends) only is 350mm.The present invention has played the effect that prevents that sublance body from falling thus.
Certainly, those skilled in the art in the present technique field will be appreciated that, the foregoing description only is to be used for illustrating the present invention, and be not as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claim of the present invention conversion, the modification of the foregoing description.
