Description
Technical Field
The utility model relates to a coke oven maintenance field, in particular to a coke oven door disc spring replacing device.
Background
The pressure of a disc spring in a bolt of the coke oven door is high, and the construction is difficult and the danger is high when the disc spring is replaced. Meanwhile, the weight of the door bolt is that maintenance personnel can not move and lift the door bolt, but the door bolt occupies a field crane, so that the crane can not exert the capacity of the door bolt, and the maintenance progress is influenced. Therefore, a replacement device is required.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a coke oven door disc spring replacing device, which reduces the work danger coefficient and improves the work efficiency.
In order to achieve the above object, the utility model adopts the following technical scheme:
coke oven furnace gate dish spring changes device, including overhead hoist and keeper dismounting device, overhead hoist includes the frame gallows, is equipped with hand-drive block on the frame gallows, and keeper dismounting device can dismantle with hand-drive block and be connected, and keeper dismounting device includes backup pad, bottom suspension fagging, and the long screw rod is worn to overlap at the both ends of going up backup pad and bottom suspension fagging, and it is spacing that the nut is passed through to the upper end of long screw rod, goes up and is equipped with the jack between backup pad and the bottom suspension fagging.
The footing of frame gallows be equipped with the universal wheel.
And a lifting ring connected with the manual hoist is arranged at the top of the upper supporting plate.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses reduce the work danger coefficient, improved work efficiency, do not occupy the crane.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic view of the present invention.
In the figure: frame gallows 1, hand hoist 2, go up backup pad 3, bottom suspension fagging 4, long screw 5, nut 6, jack 7, universal wheel 8, dish spring upper cover plate 9, keeper 10, dish spring 11.
Detailed Description
The following further describes the embodiments of the present invention with reference to the attached drawings:
according to the figures 1-2, the coke oven door disc spring replacing device comprises a lifting device and a door bolt dismounting device, wherein the lifting device comprises a frame type lifting frame 1, a manual hoist 2 is arranged on the frame type lifting frame 1, the door bolt dismounting device can be detachably connected with the manual hoist 2, the door bolt dismounting device comprises an upper supporting plate 3, a lower supporting plate 4, long screw rods 5 are sleeved at two ends of the upper supporting plate 3 and the lower supporting plate 4, the upper ends of the long screw rods 5 are limited through nuts 6, and jacks 7 are arranged between the upper supporting plate 3 and the lower supporting plate 4.
The footing of frame gallows 1 be equipped with universal wheel 8.
And a lifting ring 12 connected with the manual hoist 2 is arranged at the top of the upper supporting plate 3.
A method for replacing a disc spring of a coke oven door comprises the steps of flatly laying the coke oven door at a maintenance station, detaching two pairs of angle bolts of an upper cover plate 9 of the disc spring, hoisting a bolt detaching device to the upper side of a bolt 10 by a hoisting device, connecting a long screw rod 5 with a screw hole of the detached bolt, and supporting a lower supporting plate 4 at the top of the bolt 10. And pressurizing the jack 7 to prop against the bolt 10, and releasing the pressure of the disc spring 11 after removing the rest bolts of the upper cover plate 9 of the disc spring to the jack 7. The bolt dismounting device is dismounted, the lifting device is used for lifting the bolt 10 away, and the disc spring 11 is taken out for replacement.
The above is only the basic principle of the present invention, not to the present invention makes any limitation, all the bases of the present invention are the same changes and modifications to the above, all within the scope of the protection scheme of the present patent technology.
