Description
The utility model relates to a kind of device that converter oxygen lance anti-fall falls that is used for.
For guaranteeing the safety in production in steelwork converter workshop, anti-block rifle crashes into explosion caused accident in the converter, needs to be equipped with the oxygen lance anti-fall dropping control device on the oxygen lance lifting bogie.The oxygen lance anti-fall dropping control device that present domestic steelworks is equipped with is commonly Nippon Steel's formula oxygen lance anti-fall dropping control device, this device is made up of pulley, pulley base, lever group, connecting rod and brake component, on pulley base, below the pulley spring is housed, brake component is made of voussoir, slide and friction plate.When oxygen rifle works better, oxygen rifle windlass is mentioned pulley by wireline, spring is compressed under the action of gravity of dolly and oxygen rifle, pulley base moves up with respect to vehicle frame, drive the lever group and rotate, thereby make connecting rod to pressing down voussoir, have guide groove to connect between voussoir and slide, move right simultaneously when voussoir moves down, make the distance of a safety of friction plate deorbit.Oxygen rifle dolly weightlessness when wire cable rupture, spring is released, and above-mentioned member inverse motion makes friction plate push down track brake.The brake component of said apparatus has the following disadvantages: 1. to the requirement height of friction plate frictional coefficient, thereby brake unreliable, the time have the rifle of bob accident to take place.2. if brake successfully, it is too tight then to block rail, removes difficulty, and workman's working aloft is dangerous big.3. limit because of structure, friction plate and interorbital gap are little, also may block rail when not braking, and produce thereby hinder.
The purpose of this utility model is to improve at defective brake component in Nippon Steel's formula antidrop device, to solve the above-mentioned deficiency that exists.
The technical solution that realizes the utility model purpose is: the converter oxygen lance anti-fall dropping control device, by pulley, pulley base, the lever group, connecting rod and brake component are formed, on pulley base, spring is housed below the pulley, the lever group is installed in the both sides of pulley base by hinge, connecting rod and lever group link by hinge, brake component is by friction plate, brake shoe, brake rod, pull bar, bearing constitutes, the friction plate nail is on brake shoe, between friction plate and brake shoe, be provided with the adjustment pad, the two ends of brake rod link with bearing and brake shoe respectively with hinge, be provided with extension spring between brake shoe and brake rod, the two ends of pull bar connect with brake rod and connecting rod with hinge, vertically be installed in the top of brake rod, establish a stage clip in the pull bar.
The utility model adopts the brake shoe structure, and the adjustment pad is set between friction plate and brake shoe, and is low to the frictional coefficient requirement of friction plate to adjust the position of friction plate on brake shoe, thereby braking is reliable.The purposes of establishing a stage clip in the pull bar is to help dismounting after the braking, and pushes down brake rod in case the brake rod contact track that upwards takeoffs during the oxygen lance lifting bogie lifting with spring force.Owing to adopted the brake rod structure, make that the dismounting after the braking is very easy, as long as lifting force is balance lifting dolly and oxygen rifle gravity.This device reliable operation, simple in structure, easy for installation, to existing oxygen gun apparatus be easy to the configuration.

Below in conjunction with accompanying drawing the utility model is further described:
The converter oxygen lance anti-fall dropping control device, form by pulley 13, pulley base 12, lever group 11, connecting rod 7 and brake component 10, on pulley base 12, below the pulley 13 spring 14 is housed, lever group 11 is installed in the both sides of pulley base 12 by hinge, and connecting rod 7 and lever group 11 link by hinge.Brake component 10 is made of friction plate 1, brake shoe 3, brake rod 8, pull bar 5, bearing 9, friction plate 1 nail is on brake shoe 3, be provided with adjustment pad 2 at friction plate 1 and 3 of brake shoes, the two ends of brake rod 8 link with bearing 9 and brake shoe 3 respectively with hinge, 8 of brake shoe 3 and brake rods are provided with extension spring 4, the two ends of pull bar 5 connect with brake rod 8 and connecting rod 7 with hinge, vertically are installed in the top of brake rod 8, establish a stage clip 6 in the pull bar 5.Brake shoe 3 can rotate in ± 2 °～4 ° scopes around the hinge point on the brake rod 8.The head of brake rod 8 has the chamfering of 1mm～2mm.
Mode of operation: when oxygen rifle works better, oxygen rifle windlass is mentioned pulley 13 by wireline, spring 14 is compressed under the action of gravity of dolly and oxygen rifle, pulley base 12 moves up with respect to vehicle frame 15, driving lever group 11 rotates, thereby make connecting rod 7 to pressing down pull bar 5, drive brake rod 8 by pull bar 5 and rotate, make friction plate 1 deorbit on the brake shoe 3.When wire cable rupture,, realize braking because the effect connecting rod 7 of spring 14 with up, drive brake rod 8 by pull bar 5 and rotates, thereby make the friction plate 1 on the brake shoe 3 compress track.
This device is low to the frictional coefficient requirement of friction plate 1, thereby braking is reliable.The brake shoe 3 of design can be around the hinge point on the brake rod 8 ± 2 °～and 4 ° of scopes rotate, and help friction plate 1 and contact with the good of track, thereby make braking more reliable, and the while has also been reduced installation requirement.Make antidrop device not hinder the oxygen lance lifting bogie operation, under the less prerequisite of connecting rod 7 strokes, need increase substantially friction plate 1 and interorbital gap, the head of brake rod 8 there is the suitable chamfering of 1mm～2mm for this reason, and has designed the extension spring 4 that is hung on the brake rod 8 to hold brake shoe 3.
This device can be widely used in the converter steelmaking workshop, is applicable to that also revolving furnace sublance is anti-fall.
