Abstract
The utility model relates to a blast furnace smelting auxiliary device, especially a furnace roof hydraulic cylinder lifting structure in blast furnace smelting, which comprises hydraulic cylinders, pins, hangers, a support and crossbeams; the support is a frame type structure; a crossbeam is welded on the frame at the middle position of the top by a rib plate; the hangers are arranged and mounted on the bottom of the crossbeam by connecting pieces; the lower part of every hanger is mounted with a hydraulic cylinder by a pin. In the utility model, the original crossbeam mounted with hangers is move to under the support; the number of hangers mounted on the crossbeam is changed from one to multiple; every hanger is rotated by 90 degrees on the horizontal direction; while the pins form mounting the hydraulic cylinders are respectively disposed on three different horizontal line; thereby, maintaining any hanger will not bring inconvenience to other components in the operation space, the time spent for maintaining one hydraulic cylinder is shortened from 80 minutes to 10 minutes; and the labor efficiency is greatly improved.
Description
Technical field:
The utility model relates to the blast-furnace smelting auxiliary facility, specifically a kind of blast-furnace smelting furnace roof hydro-cylinder hoisting structure.
Background technology:
In the tradition blast-furnace smelting industry, the furnace roof hydro-cylinder auxiliary facility that is absolutely necessary.Generally, the furnace roof hydro-cylinder is made of hydro-cylinder, bearing pin, hanger, support, crossbeam five parts.Hydro-cylinder relies on bearing pin to connect with hanger, and hydro-cylinder is installed successively side by side, and bearing pin is on the same sea line, and both sides also have hydraulic cylinder leg, and distance is too near.Owing to use frequently, if a hydro-cylinder breaks down, middle bearing pin is not easy to take out, and needs adjacent hydro-cylinder is pulled down, and it is keeped in repair again.Like this, operation was both inconvenient, had wasted the time again, virtually, greatly reduced efficiency.
The utility model content:
The utility model is intended to solve the many unfavorable factor of above-mentioned furnace roof hydro-cylinder in actually operating and maintenance, and a kind of blast-furnace smelting furnace roof hydro-cylinder hoisting structure of being convenient to the dismounting maintenance, improving work efficiency is provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of blast-furnace smelting furnace roof hydro-cylinder hoisting structure, comprise hydro-cylinder, bearing pin, hanger, support, crossbeam, support is the frame-type structure, described frame roof mid-way is welded with a crossbeam that is solidified as a whole with it by gusset, described crossbeam underrun web member is arranged hanger is installed, and each hanger bottom is lifted with hydro-cylinder by bearing pin respectively.
Compared with prior art, the crossbeam that the utility model will be installed hanger originally moves on to the support below, and a crossbeam is only installed a hanger change crossbeam into and arrange a plurality of hangers are installed, make each hanger half-twist in the horizontal direction, the bearing pin of lifting hydro-cylinder then is in respectively on three sea lines.Therefore, this hoisting structure of the utility model can be as required keeps in repair any one hanger wherein, under the prerequisite that satisfies service requirements fully, with keeping in repair the 80 minutes time of a hydro-cylinder originally, shorten to 10 minutes, efficiency can improve 80%.
Description of drawings:
Fig. 1 is a structural representation front view of the present utility model.
Fig. 2 is a structural representation side-view of the present utility model.
Among the figure: support 1, crossbeam 2, web member 3, hanger 4, bearing pin 5, hydro-cylinder 6, gusset 7.
Embodiment:
Referring to Fig. 1 Fig. 2, the support 1 of this blast-furnace smelting furnace roof hydro-cylinder hoisting structure is the frame-type structure, its crown center position is welded with a crossbeam that is solidified as a whole with it 2 by gusset 7, these crossbeam 2 underrun web members 3 are vertically arranged three hangers 4 are installed, and each hanger 4 bottom is lifted with a hydro-cylinder 6 by bearing pin 5 respectively.Three bearing pins 5 are on three sea lines, and when wherein any one dismounting, installation, other parts all can not made troubles on the operating space.
Claims (1)
