Abstract
The utility model relates to a lifting appliance for replacing a furnace top roller of an annealing furnace. The lifting appliance comprises an arc hoisting frame and permanent magnet hoisting devices which are arranged at both sides of the arc hoisting frame and are used for adsorbing strip steels outside a furnace roller. When the furnace shuts down to replace the furnace top roller, only a furnace cover needs to be opened, so that the permanent magnet hoisting devices are close to the strip steels at the upper part of the furnace top roller; after the strip steels are adsorbed, the furnace top roller can be replaced; and then the permanent magnet hoisting devices are separated from the adsorbed strip steels, so that a roller replacement task can be completed. Not only is the mode without breaking strips time-saving and labor-saving after the lifting appliance is adopted, but also the lifting appliance is convenient to operate, so that the operating rate of the annealing furnace is improved.
Description
Technical field
The utility model relates to a kind of suspender that is used to change annealing furnace furnace roof roller.
Background technology
The vertical annealing furnace that continuous cold rolling band steel is used needs to change the furnace roof roller generally speaking when shutdown maintenance.Because of the band steel in the process of annealing, operation constantly on each furnace roller, so, want to change the furnace roof roller, prior art is to adopt earlier the band steel in the stove to be cut off, and reserves messenger on the band steel, and then changes the furnace roof roller.After the furnace roof roller is changed, more open circuited band steel is pulled out mode tape splicing, and wear band again according to the passage of furnace roof roller with welding, investigate according to the scene, adopt the mode of this kind replacing furnace roof roller generally to need 6-8 consuming time hour, length not only consuming time, operation are loaded down with trivial details, and the waste great amount of manpower; Wearing in the band tape splicing process after maintenance particularly, the easiest belt phenomenon that occurs, the generation of this phenomenon can influence the production efficiency of cold rolling unit annealing furnace greatly.
Summary of the invention
The purpose of this utility model provides a kind of mode of magnetic of utilizing and changes the furnace roof roller, to solve the suspender that is used to change annealing furnace furnace roof roller of problem such as the low and cost height of operating rate.
The suspender that the utility model proposed is used to change annealing furnace furnace roof roller comprises the arc mast-up and is installed in the permanent magnetism hoisting device that is used to adsorb furnace roller external belt steel of these arc mast-up both sides.
Described mast-up has two identical arcs and a stay bearing plate that is used to be connected described two arcs, and the top of stay bearing plate is provided with a hanger.The bottom of described arc all is provided with the engaging lug of a pair of band bearing pin.
Described permanent magnetism hoisting device has a hoisting device main body and a control magnetic handle that is positioned at this hoisting device body edge portion, and the bottom of hoisting device main body is provided with and the curved portions that the furnace roller profile is complementary of changing.
The arc mast-up of suspender employing and the permanent magnetism hoisting device that are used to change annealing furnace furnace roof roller that the utility model proposed, when annealing furnace overhauls, only need its bell is opened, make the band steel of permanent magnetism hoisting device near furnace roof roller top, it is risen after picking up is replaceable furnace roof roller, the permanent magnetism hoisting device is separated with the band steel that picks up can finishes the roll change task, and this mode that need not broken belt is not only time saving and energy saving, and easy to operate, thereby improved the operating rate of annealing furnace.
Description of drawings
Accompanying drawing 1 is that the utility model is carried being used to of being proposed and changed the surface structure scheme drawing of an embodiment of suspender of annealing furnace furnace roof roller;
Accompanying drawing 2 is the surface structure scheme drawings of an embodiment of permanent magnetism hoisting device among Fig. 1.
The specific embodiment
Referring to Fig. 1, this figure provides that the utility model proposes is used to change the overall appearance structure of an embodiment of suspender of annealing furnace furnace roof roller, this suspender has an arc mast-up 1, arc mast-up 1 has two identical arcs 11, the bottom of each arc 11 all is provided with the engaging lug 13 of two band bearing pins 12 symmetrically, two arcs 11 are fused by stay bearing plate 14, and the top of stay bearing plate 14 is provided with a hanger 15; This suspender has 2, four permanent magnetism hoisting devices 2 of four permanent magnetism hoisting devices and is fixed among the engaging lug 13 of arc 11 bottoms by bearing pin 12 respectively in twos.
Referring to Fig. 2, this figure provides the overall appearance structure of permanent magnetism hoisting device in the foregoing description, this permanent magnetism hoisting device 2 has a hoisting device main body 21, the bottom of hoisting device main body 21 is a curved portions 23, the arc of this curved portions 23 is complementary with the furnace roller profile radian of changing, and the limit portion of hoisting device main body 21 is provided with a control magnetic handle 22.
When blowing out replacing furnace roof roller uses this suspender, with overhead traveling crane this suspender of slinging, make it near the band steel on furnace roof roller, control magnetic handle 22 is adjusted to made permanent magnetism hoisting device 2 that magnetic state be arranged, be with steel to be picked up at this moment by permanent magnetism hoisting device 2, the operative employee begins to change the furnace roof roller, after having changed, control magnetic handle 22 is transferred to and is made the 2 no magnetic state of permanent magnetism hoisting device, falls the band steel, with overhead traveling crane this suspender is removed, promptly finished the furnace roof roller work of changing.
