The spacing general use approach switch of the vertical roaster clad of steel mill ladle lifting or limit switch control, interlocking often lost efficacy, and position higher be not easy to safeguard change.Institute's interlocking is all spacing by one, breaks down and will affect whole system.Service life and the production efficiency of ladle are had a strong impact on.
Summary of the invention
In order to solve the problem of making steel the spacing Problem of Failure of ladle baking facility clad, improving the reliability of the spacing interlocking of clad, the invention discloses the spacing interlock of a kind of vertical roaster clad lifting, this equipment adopts height limiter to carry out spacing chain control, have lightweight, volume is little, installation and debugging are convenient, it is sensitive and accurate to respond, the steady advantage such as reliable, long service life, setting height(from bottom) limiter on roaster gearbox axis, control more steadily reliable, longer service life of the each interlocking of roaster, be convenient to Maintenance and Repair.In addition, another technical problem that will solve of the present invention is the method for carrying out spacing chain operation that uses this spacing interlock.
The spacing interlock of a kind of vertical roaster clad lifting, comprising: bracing frame, height limiter, reductor shaft, it is characterized in that: the control of the spacing employing height limiter of vertical roaster clad lifting, height limiter is connected with reductor shaft end, and height limiter is fixed on bracing frame.Adopt height limiter to efficiently solve spacing frequent failure problem before, adopted height limiter, reliable in action, it is convenient to control, and result of use is remarkable.Can be spacing according to any adjusting of clad height, improve validity and the flexibility of overhaul of the equipments and maintenance.Height limiter can be realized multichannel output, and each road output all can realize separately interlocked control, adopts height limiter to realize single interlocked control, can not have influence on other interlocking, thereby reduce fault effects face.
As a modification of the present invention, described bracing frame is made up of steel plate for level altitude stop, be provided with retaining thread hole, height limiter bearing through hole, bracing frame is fixed on roaster base, after adopting this design, can improve the rigidity of height limiter, the precision of hoisting depth limiter.
As a modification of the present invention, described reductor shaft front end is provided with the groove of concentric degree, groove is square and the embedding of height limiter spool shaft phase, the degree of depth is 1-2cm, after adopting this design, facilitate height limiter to be connected with reduction box, can ensure height limiter job stability, increase work efficiency.
In order to make the spacing interlock of vertical roaster clad lifting realize its function, using method of the present invention comprises following step:
(1) motor rotates and drives reductor shaft to rotate;
(2) shaft rotates and drives height limiter reel to rotate;
(3) spool shaft drives worm screw, worm gear to rotate;
(4) cam on worm-wheel shaft also rotates thereupon;
(5) while forwarding a certain position to, the flange portion of cam contacts with limit switch;
(6) limit switch action;
(7) cut off and rise or decline power source;
(8) roaster clad is stopped on extreme position;
(9) can regulate spacing by adjusting height limiter, realize positioning function.
To sum up, spacing easy Problem of Failure before the spacing employing height limiter of vertical roaster clad lifting efficiently solves, adopts height limiter, reliable in action, and it is convenient to control, and result of use is remarkable.Highly non-adjustable problem before having solved, is convenient to the adjusting to roaster height, can adjust clad height according to on-site actual situations.Adopt each interlocking to separate control mode, effectively solve the problems such as buggy ladle is in the past interlocked, and clad lifting is interlocked, and coal gas is cut soon valve and interlocked by a spacing control, and after going wrong, coverage is wide, and influence surface is large.
