Description
Technical field
This utility model relates to a kind of hydraulic spanner, particularly to a kind of air pipe of blast furnace wedge dismounting hydraulic spanner.
Background technology
Such as Fig. 1, steel mill workman is carrying out when removing and installing of air pipe of blast furnace, it is necessary to first being pulled down by the bolt of air duct flange 3 with blast furnace flange 2 place, this process completes mainly by manual operation at present, operation is divided into following steps: 1. such as Fig. 2, nut 4 is first loosened by operator with spanner；2. such as Fig. 3, firmly wedge 1 is beaten with tup so that it is separate with bolt 5, thus being pulled down by bolt 5.Owing to each airduct has several bolts 5, and each blast furnace includes several airducts, and therefore, by artificial unloading's bolt, the process beaing wedge particularly with tup wastes time and energy, and efficiency comparison is low.
Utility model content
In order to overcome above-mentioned the deficiencies in the prior art, this utility model purpose there is provided a kind of air pipe of blast furnace wedge dismounting hydraulic spanner, is not only simple in structure, and can improve production efficiency and alleviate labor strength.
For achieving the above object, this utility model is by the following technical solutions:
A kind of air pipe of blast furnace wedge dismounting hydraulic spanner, including hydraulic mandril and locating piece, locating piece includes the first draw-in groove, the second draw-in groove and the extension slot that are sequentially communicated, first draw-in groove is circular, and diameter is identical with the diameter of bolt, the second draw-in groove is rectangular configuration, and the second draw-in groove dual-side is corresponding to wedge front and rear surfaces, hydraulic mandril front end is positioned at the extension slot of locating piece, and hydraulic mandril front end has threeth draw-in groove corresponding with wedge side.
Preferably, extension slot is rectangular configuration, and extension slot length, width and the degree of depth are all higher than the length of the second draw-in groove, width and the degree of depth.
Preferably, locating piece is rectangular configuration, and has handle on surface.
The beneficial effects of the utility model:
Coordinate hydraulic mandril to coordinate by locating piece, do not need loose nut when dismounting airduct, positioned rear demounting bolt and can improve production efficiency less than 2s and alleviate labor strength；Overall structure is simple.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model being described in further details, the description below is merely illustrative of, and does not limit protection domain of the present utility model.
Such as Fig. 4 and 5, a kind of air pipe of blast furnace wedge dismounting hydraulic spanner, including hydraulic mandril 11 and locating piece 10, locating piece 10 includes the first draw-in groove the 6, second draw-in groove 7 and the extension slot 8 being sequentially communicated, and the first draw-in groove 6 is circular, and diameter is identical with bolt 5 diameter, second draw-in groove 7 is rectangular configuration, and second draw-in groove 7 dual-side corresponding to wedge 1 front and rear surfaces, hydraulic mandril 11 front end is positioned at the extension slot of locating piece 10, and hydraulic mandril 11 front end has threeth draw-in groove 9 corresponding with wedge 1 side.
Extension slot 8 is rectangular configuration, and extension slot 8 length, width and the degree of depth are all higher than the length of the second draw-in groove 7, width and the degree of depth.
Locating piece 10 is rectangular configuration, and has handle 12 on surface.
Its concrete operation step:
1. the rotational hydraulic spanner when dismantling wedge, makes the 3rd draw-in groove 9 block the minor face place of wedge 1, and the first draw-in groove 6 is enclosed within stud, and wedge 1 is arranged in the second draw-in groove 7；
2. operate hydraulic mandril, by hydraulic mandril 11 action, wedge 1 is ejected；
3. the rotational hydraulic spanner when installing wedge, makes the 3rd draw-in groove 9 block the long edge position of wedge 1, and the first draw-in groove 6 is enclosed within stud, and wedge 1 is arranged in the second draw-in groove 7；
4. operate hydraulic mandril, by hydraulic mandril 11 action, wedge 1 is inserted in bolt 5.
Above only describes ultimate principle of the present utility model and preferred implementation, those skilled in the art can make many changes and improvements according to foregoing description, and these changes and improvements should belong to protection domain of the present utility model.
