1) owing to cannot guaranteeing to pull out, draw by steel wire rope and spool shaft to the depth of parallelism, often occur that gear is pulled out situation oblique and that axle is killed pulling out in being pulled through journey;
2) because steel wire rope is pulled through Cheng Zhonghui and is subject to very large tractive force pulling out, pull out be pulled through journey in because manual operation reason is easy to the situation that occurs that steel wire rope screw thread place throws off, and there is serious accident.
3) for avoiding steel wire rope to thread off, there is security incident and occur that gear is skewed the situation of killing with axle, therefore be to allow it expand to the heating of gear outer ring produce gap with hollow shaft, then pull out and draw with steel wire rope in actual mechanical process.Pull out and draw certain distance heating again after gear shrinkage, after heating, draw again a segment distance, so repeatedly until gear departs from hollow shaft, taking time and effort so very, efficiency is very low.
4), because of manual operation reason, in unloading process, be easy to occur that on gear and reel, hollow shaft binding face, by the situation of scratch, directly causes gear to be again utilized.
Summary of the invention
For the deficiency of background technology, the mode of jack apical axis for the present invention, has well avoided the generation of security incident.Simultaneously, pulling out the depth of parallelism that has guaranteed reel center and jack center in being pulled through journey, therefore needn't worry to occur the situation that gear and axle are killed, can directly with heat tape, continue constant temperature heats gear outer ring, and set directly dismounting after the force value of hydraulic jack, and pull out like this pulling rate degree even, the used time is short, removal efficiency is high, and can not drawn bad situation to occur because manual operation reason causes gear.The present invention is mainly used in the dismounting of reel gear in uncoiling on metallurgy strip equipment, coiling machine.
Technical scheme of the present invention is: a kind of provision for disengagement of reel, comprise framework, heating tape, jack, described framework one side can be blocked the gear and support reel on reel, it is characterized in that: described heating tape can be bundled on the gear of reel and to its heating, and the opposite side that framework is corresponding is installed jack.
The provision for disengagement of reel as above, is characterized in that: described framework is by H shaped steel HW200 * 200 * 8 * 12 welding fabrication.
The provision for disengagement of reel as above, is characterized in that: on the supporting surface of described reel and framework, latch wheel locates binding face perpendicularity in 0.05mm.
A method for dismounting for reel, comprises the following steps:
The gear of reel is snapped in after framework, in gear outer ring, tie up the step of ribbon heater heating;
When temperature is heated to predetermined temperature, set the force value of hydraulic jack, pressurization starts jack, jack withstands hollow shaft end face on reel, when the thrust of jack is increased to while being greater than gear and hollow shaft frictional force, because gear is blocked master, therefore, jack can slowly promote hollow shaft and gear departs from.
The method for dismounting of reel as above, is characterized in that: the temperature of described ribbon heater heating is arranged between 80 ℃ to 100 ℃.
The method for dismounting of reel as above, is characterized in that: it also comprises the step of reel center and jack center being adjusted to opposing parallel.

2, stressed large, because well having controlled the depth of parallelism of reel and hydraulic jack, therefore removal efficiency is improved, meanwhile, also improved the security in operating process;
3, avoided causing gear to be drawn bad situation to occur in manual operation process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Description of reference numerals: 1 is framework, 2 is heating tape, 3 is jack.
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, the provision for disengagement of reel of the present invention comprises framework 1, heating tape 2, jack 3.Framework 1 is by H shaped steel HW200 * 200 * 8 * 12 welding fabrication, and it has simple in structure, stressed large, the feature that cost is low.Framework 1 one sides are for blocking the gear and support reel on reel.Heat gear for being bundled on gear heating tape 2.The opposite side that framework is corresponding is installed jack 3.Jack 3 of the present invention is hydraulic jack.
In order to control the depth of parallelism at reel center line and hydraulic jack center, and guarantee not occur that the stuck phenomenon of gear occurs in pulling out the process of drawing.On framework 1 of the present invention, binding face and the roll support face of latch wheel were all processed.Concrete processing method is: framework is positioned on 8m CNC planer type milling machine, take framework bottom surface as benchmark, according to framework manuscript paper size milling roll support face.Then, Installing machine tool angle square milling head, 3 place's binding faces of latch wheel on milling framework 1.Finally, beat the form and position tolerance that table detects latch wheel binding face on roll support face and framework 1, require roll support face and 3 place's binding face perpendicularity in 0.05mm.
