Abstract
The utility model relates to a distribution chute overhauling device, which comprises a furnace shell, a large furnace top platform and an overhauling crane. The large furnace top platform and the overhauling crane are arranged outside the furnace shell, wherein a furnace top framework is arranged on the large furnace top platform, and a small furnace top framework is arranged on the furnace shell. The distribution chute overhauling device is characterized by also comprising an overhauling hanger, an overhauling beam is arranged on the large furnace top platform, a track is arranged on the overhauling beam, the overhauling crane is arranged on the track and can move along the track, and the overhauling hanger is connected with the overhauling crane through a hanging rope and can realize removal and installation of a distribution chute along with movement of the overhauling crane. The overhauling beam penetrates through the small furnace top framework and extends out of the furnace top framework without interference against the small furnace top framework, thereby preventing the effect on the weighing accuracy of the weighing system. The overhauling crane drives the overhauling hanger to move on the overhauling beam for removal and installation of the distribution chute, and no platform for removal and installation is needed. Therefore, the utility model has short lifting distance and simple structure, can be flexibly, rapidly and conveniently used, and can be easily operated.
Description
Technical field
The utility model belongs to metallurgical industry, relates to a kind of apparatus for examination and repair of distributor chute, relates in particular to a kind of apparatus for examination and repair of novel and jar non-bell furnace top charging equipment distributor chute.
Technical background
Non-bell furnace top charging equipment comprises the furnace roof large platform that is arranged on furnace roof, be arranged on furnace top frame on the furnace roof large platform, be arranged on the maintenance beam on the furnace top frame and be arranged on the distributor chute of furnace roof.Distributor chute is a vitals in the non-bell furnace top charging equipment, and its repair rate is higher, to the maintenance of distributor chute be by above-mentioned maintenance beam with the distributor chute dismounting that damages, and intact distributor chute is installed.
Novel and jar no bell passes through to change the batch can shape, make the materials flow center as far as possible near the blast furnace medullary ray, to descend clack box to disintegrate and be divided into three parts, make the dismounting of all can disintegrating respectively of blanking lock, lower seal valve, remedied some inherent defects of tradition and jar no bell, making also, a jar no bell has had bigger vigor.Yet, new improvement has also brought new problem, in order to guarantee the accuracy of weighing system, on furnace shell, set up supporting structure furnace roof small frame, the maintenance beam that is provided with on the furnace roof small frame hangs length and limited by amount of deflection, distributor chute can't be shifted out outside the furnace roof small frame, must come the dismounting distributor chute by the furnace roof crane, and the furnace roof crane need pass down the clack box platform from top to bottom, blanking lock platform and weighing batch can support platform, need during the dismounting distributor chute to descend the clack box platform, the movable platform of blanking lock platform and weighing batch can support platform and walking beam are removed, therefore, cause the maintenance dismounting long in time limit and quite complicated.
The utility model content
The purpose of this utility model be to provide a kind of can be fast, the apparatus for examination and repair of dismounting distributor chute easily.
The purpose of this utility model is achieved in that a kind of apparatus for examination and repair of distributor chute, comprise furnace shell, be arranged on the furnace roof large platform and the maintenance crane of furnace shell outside, described furnace roof large platform is provided with furnace top frame, described furnace shell is provided with the furnace roof small frame, it is characterized in that: also comprise the maintenance suspender, on the described furnace roof large platform maintenance beam is set, on the described maintenance beam track is set, described maintenance crane places on the described track and can be along moving on the described track, and described maintenance suspender is connected with described maintenance crane also and can moves the dismounting of enforcement to distributor chute with overhauling crane by lifting rope, install.
For compact construction is simple, described maintenance beam passes the furnace roof small frame and stretches out furnace top frame, and described maintenance beam and furnace roof small frame do not interfere, and does not therefore influence the accuracy of weighing system.
In order to guarantee the reliability and stability of apparatus for examination and repair, above-mentioned maintenance beam is two and parallel and be symmetricly set on the both sides at body of heater center.
When distributor chute was overhauled, the maintenance crane drove the maintenance suspender and moves along above-mentioned track, entered in the furnace roof small frame, and the maintenance suspender is implemented dismounting to the distributor chute that damages, and intact distributor chute is installed, and the distributor chute of dismounting is shifted out.
The utility model has following beneficial effect, maintenance beam of the present utility model passes the furnace roof small frame and stretches out furnace top frame, do not interfere, therefore do not influence the weighing precision of weighing system, drive the maintenance suspender by the maintenance crane and on the maintenance beam, move dismounting, the installation of implementing distributor chute with the furnace roof small frame, need not the dismounting platform, not only lifting distance is short, uses flexibly rapid and convenient, and it is simple in structure, easy to operate.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model embodiment front view;
Fig. 2 is Fig. 1 side-view.
Embodiment
Embodiment, a kind of apparatus for examination and repair of distributor chute, comprise furnace shell 9, be arranged on the furnace roof large platform 1 of furnace shell 9 outsides, maintenance crane 4 and maintenance suspender 5, furnace roof large platform 1 is provided with furnace top frame 2, furnace shell 9 is provided with furnace roof small frame 3, maintenance beam 6 is set on the furnace roof large platform 1, maintenance beam 6 is two and parallel and be symmetricly set on the both sides at body of heater center, maintenance beam 6 passes furnace roof small frame 3 and stretches out furnace top frame 2, on the maintenance beam 6 track 7 is set, maintenance crane 4 places on the track 7 and can move along track 7, and maintenance suspender 5 is connected with maintenance crane 4 and can enters in the furnace roof small frame 3 with maintenance crane 4 by lifting rope 8 implements dismounting to distributor chute, install.
When distributor chute is overhauled, maintenance crane 4 drives maintenance suspender 5 and moves along track 7, enters in the furnace roof small frame 3, and the distributor chute of 5 pairs of damages of maintenance suspender is implemented dismounting, install intact distributor chute, drive maintenance suspender 5 by maintenance crane 4 then the distributor chute of dismantling is shifted out.
