Description
Technical field
The utility model relates to a kind of suspender, especially a kind of closed type big mill Sling for lifting roller.
Background technology
Big mill, is the equipment for shaped steel first rolling process, the large body profile of the shaped steel that need to be shaped, therefore roll-force is larger, the roll of employing is all the very large rolls of weight.
Closed type big mill refers to the top cover shape that casing upper surface is as a whole, only on casing side, is provided with the big mill of opening.In closed type big mill, the weight of single roll reaches and approaches 20 tons of left and right, simultaneously in the time that maintenance is changed due to cannot be directly from above lifting, the unusual trouble therefore the dismounting and change of roll seems, each maintenance is changed and all can be expended a large amount of manpowers and time.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is: how to provide a kind of simple in structure, easy to use, the replacing that can be used in closed type big mill roll is installed, shorten disassembly and assembly time, the closed type big mill Sling for lifting roller of raising labour efficiency.
In order to solve the problems of the technologies described above, in the utility model, adopt following technical scheme.(in this programme, being described taking suspender use state as benchmark)
A kind of closed type big mill Sling for lifting roller, it is characterized in that, comprise the suspender main body of strip shape, suspender main body entire length is greater than closed type big mill casing top to the height distance between the interior lowest part roll of casing, suspender main body upper end has the elbow that 90 degree bendings turn to, lower end is provided with connector, on described connector, on the side consistent with elbow direction, be provided with and the roll end axle mounting hole of closed type big mill roll end axle coupling, on elbow, there is the suspension hook rope sling upwards arranging.
When suspender of the present utility model uses, first the bearing removal 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, by crane, suspender lower end is moved to roll end by displacement, roll end axle is inserted in the roll end axle mounting hole being installed on the connector of suspender main body lower end, then the bearing removal of the roll other end is fallen, reliable crane is gone out roll handling, completes dismounting and change.Therefore can facilitate the replacing dismounting of roll, there is feature simple in structure, convenient to operation simultaneously.
As optimization, described suspension hook rope sling is connected on elbow by lifting rope bindiny mechanism, described lifting rope bindiny mechanism, comprise and be positioned at an adapter shaft, adapter shaft lower end is fixedly connected in a mounting groove on elbow, adapter shaft upper end folds rotationally and is provided with two clamping plates, and two clamping plates upper end folds and is provided with a rope sling roller, and hang on rope sling roller described suspension hook rope sling lower end.
Optimize like this, be due to suspender own wt and roll weight all very heavy, therefore adopt above-mentioned lifting rope bindiny mechanism to realize the connection of lifting rope rope sling, can improve Joint strenght, guarantee handling stability, can limit well the rotational freedom of unnecessary direction, and ensure the rotational freedom of necessary direction simultaneously.
As optimization, also comprise that roll assists bindiny mechanism, described roll is assisted bindiny mechanism, comprise the basifacial journal stirrup of side that is arranged on elbow place side in suspender main body, on journal stirrup, be provided with connecting bore, also comprise an auxiliary lifting rope, auxiliary lifting rope upper end is connected on the connecting bore of journal stirrup, and lower end has the rope sling of and roll end axle coupling and establishes and articulate for the end axle sleeve that deviates from roll end axle mounting hole one end with roll.
After optimizing like this, in the time that suspender is worked, when inserting, big mill roll one end end axle is installed to after the mounting hole of connector, the lower end of auxiliary lifting rope can be overlapped on the end axle that receive the roll other end and formed and articulate, make the suspender breaker roll application of force better, make it keep balance, ensure the steadily reliable and safety of handling process.
Further, described journal stirrup can be vertical arrange multiple.Like this, in the time of the roll of above and below diverse location in dismounting big mill, can select the journal stirrup of coupling to connect, make the use of auxiliary lifting rope can not produce and interfere with big mill frame, guarantee the smooth and easy of handling process.
Again further, on auxiliary lifting rope, be also provided with rope length regulating device, described rope length regulating device, comprise the adjusting screw(rod) being connected to separately on auxiliary lifting rope upper semisection and lower semisection, screw thread on adjusting screw(rod) oppositely arranges, and between two adjusting screw(rod)s, corresponding screw thread is connected with a telescopic setting nut.
Like this, when auxiliary lifting rope connects after the roll other end, can it be tightened by rope length regulating device, reach the breaker roll other end and apply better the effect of pulling force, this rope length regulating device self has advantage simple in structure, easy to adjust simultaneously.
As another optimization, also comprise suspender body level(l)ing mechanism, described suspender body level(l)ing mechanism comprises adjusting rope, supporting rollern and hook, described hook is arranged at downwards and on connector, deviates from roll end axle mounting hole one middle side part, described supporting rollern is arranged on the back side in suspender main body knee by the support frame of a U-shaped structure, it is upper that described adjusting rope lower end is articulated in hook, 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.
After optimizing like this, before and after handling, in process, can lean on adjusting rope to apply a pulling force that deviates from roll direction to suspender main body lower end, make suspender body can keep vertical state always, just corresponding with the roll of horizontality, more convenient installation while making to install, more convenient dismounting when dismounting.
Further, on described adjusting rope, a rope length regulating device also can be set.Like this, can in advance adjusting rope upper end be fixed on suspension hook rope sling or suspension hook, then adjust the length of adjusting rope by rope length regulating device, to facilitate regulating rope tension to adjust, make suspender body can keep vertical state always, simultaneously this rope length regulating device have simple in structure, advantage efficiently easy to adjust.
In sum, suspender of the present utility model, the replacing that can be used in auxiliary closed type big mill roll is installed, and can shorten disassembly and assembly time, raises labour efficiency, and has advantage simple in structure, easy to use simultaneously.
