Description
Technical field
The present invention relates to a kind of closed type big mill roll method for dismounting.
Background technology
Big mill is the equipment for shaped steel first rolling process, needs to be shaped the general configuration of shaped steel, therefore roll-force is comparatively large, and the roll of employing is all the very large rolls of weight.
Closed type big mill refers to and on cabinet sides, is only provided with the big mill of opening by the dome shape that casing upper surface is as a whole.In closed type big mill, the weight of single roll reaches close to about 20 tons, simultaneously when examine and replace owing to cannot directly lift by crane from top, therefore the auxiliary dismounting of crane cannot be adopted, the dismounting and change of roll is seemed unusual trouble, and each examine and replace all can the manpower of at substantial and time.
Summary of the invention
For above-mentioned the deficiencies in the prior art, technical matters to be solved by this invention is: how to provide a kind of hanger structure of employing simple, it is convenient to implement, and remove and install the time short, efficiency is high and the closed type big mill roll method for dismounting that safety is good.
In order to solve the problems of the technologies described above, in the present invention, have employed following technical scheme.(in this programme, with suspender using state for benchmark is described)
A kind of closed type big mill roll method for dismounting, it is characterized in that, adopt the suspender of a curved shape, one end that suspender lower end and roll are first removed is fixedly connected with, suspender upper end is avoided casing by bending position and is interfered backward hanging oneself to hang on the suspension hook of crane, make lift hook position be positioned at suspender install roll after on integrally-built midperpendicalar, then sling after roll weight by crane and disassemble roll other end bearing, then by crane, roll is hung out big mill casing.
This method specifically comprises the following steps:
A, first obtain the suspender of following structure, described suspender comprises the suspender main body of strip shape, suspender entire body length is greater than the height distance in closed type big mill cabinet top to casing between lowest part roll, suspender main body upper end has 90 degree and bends the elbow turned to, elbow has the suspension hook rope sling upwards arranged, suspender main body lower end is provided with connector, side consistent with elbow direction on described connector is provided with the roll end axle mounting hole with closed type big mill roll end axle coupling, described roll makes roll end axle be installed to after in roll end axle mounting hole in the horizontal direction, described suspension hook rope sling is positioned on the gravity vertical of suspender and roll entirety just, suspender also comprises roll and assists bindiny mechanism, and bindiny mechanism assisted by described roll, comprises an auxiliary lifting rope, and auxiliary lifting rope upper end is connected in suspender main body, and lower end has the rope sling of and roll end axle coupling, suspender also comprises suspender body level(l)ing mechanism, described suspender body level(l)ing mechanism comprises adjusting rope and supporting rollern, described supporting rollern is arranged on the back side at suspender main body curves place, described adjusting rope lower end is connected to the back side that connector deviates from roll axle head mounting hole side, and upper end is upwards through the limited backward upper extension of support roller medial surface and for being connected with the suspension hook at suspension hook rope sling place, described auxiliary lifting rope and described adjusting rope are provided with the rope length regulating device that can regulate rope progress row,
When b, dismounting roll, first the bearing removal on the end axle of closed type big mill roll one end is fallen, then the easing out line cover of this suspender is hung on the suspension hook of crane, the length being changed adjusting rope by the rope length regulating device on adjusting rope makes suspender main body keep vertical state, hoist lifting hook is displaced to big mill cabinet top, makes the insertion of roll end axle be installed in the roll end axle mounting hole on the connector of suspender main body lower end;
C, then the bearing removal on roll other end end axle to be fallen, auxiliary lifting rope extension is made by regulating the rope length regulating device on auxiliary lifting rope, again the rope sling of auxiliary lifting rope lower end is socketed on this end roll end axle, regulate the rope length regulating device on auxiliary lifting rope to shorten the length of auxiliary lifting rope, make auxiliary lifting rope be tensioned state; Start crane back cabinet of being sling by roll and go out big mill casing along roll mandrel to parallel motion, complete dismounting.
This method, have employed the suspender of unique texture, make crane can avoid the interference of milling train casing by suspender, realize the handling dismounting to closed type big mill roll, and then shorten removal time, improve efficiency, and improve the safety of dismounting, it is simple that the suspender simultaneously adopted has structure, implements advantage easily.
As optimization, in the suspender of employing, roll assists bindiny mechanism also to comprise to be arranged on the journal stirrup of the side lower of side, elbow place in suspender main body, journal stirrup is provided with connecting bore and described journal stirrup be vertical arrange multiple; During dismounting, the connecting bore that suitable journal stirrup is selected to be connected in auxiliary lifting rope upper end is interfered to avoid auxiliary lifting rope and big mill casing to produce.
Like this, auxiliary lifting rope is reliably easy to connect, and during the roll of dismounting differing heights position, auxiliary lifting rope can be connected on the journal stirrup of diverse location, interferes, improve safety to avoid assisting lifting rope and casing to produce when dismounting better.
As optimization, in the suspender of employing, also comprise one in described suspender body level(l)ing mechanism and be arranged at hook connector deviating from roll end axle mounting hole one middle side part downwards, during dismounting, described adjusting rope lower end is articulated on hook.
Like this, adjusting rope connection is more convenient.
As optimization, in the suspender adopted, the rope length regulating device that described auxiliary lifting rope and described adjusting rope are arranged, comprise the adjusting screw(rod) be connected to separately on auxiliary lifting rope or adjusting rope upper semisection and lower semisection, screw thread on adjusting screw(rod) is oppositely arranged, and between two adjusting screw(rod)s, corresponding screw thread is connected with a telescopic setting nut; The length of section is coordinated to change rope by rotating adjusting nut change adjusting screw(rod) and setting nut when adjusting rope is long long.
After such optimization, have fast easy to adjust, the advantages such as control process is more reliable and more stable.
In sum, the present invention can rely on suspender, and adopt the dismounting of crane realization to closed type big mill roll, highly shortened removal time, improve efficiency, safety is simultaneously very good; It is simple that the suspender adopted in method in addition has structure, implements the advantages such as convenient.
