Abstract
The utility model relates to a locking device that is used for a vertical shaft of an electric stove, which comprises an inclined-block lock head that is arranged on the bottom of the vertical shaft, and a pull rod that is arranged inside a locking framework and is connected with a hydraulic cylinder, wherein, the pull rod can be matched with the inclined surface of the inclined-block lock head in a wedging way. The locking device has simple structure, and effectively breaks down the stress through the wedged locking design of the inclined surface, so that the mechanism can be reliably locked, and the safety, the reliability and the service life of the locking device are ensured.
Description
[technical field]
The utility model relates to a kind of fixture of steel-smelting electric furnace vertical shaft.
[background technology]
The effect of Electric furnace shaft locking device is vertical electric furnace locking vertical shaft chassis when smelting, and guarantees that vertical shaft is not subjected to displacement in electric furnace charging and the smelting process.The former structure of existing vertical shaft locking device as depicted in figs. 1 and 2.
Former Electric furnace shaft locking device operation principle and characteristics are: the vertical shaft chassis reaches the electric furnace working position, and the removable pin 1 of Electric furnace shaft lock is upwards jacking under the effect of hydraulic cylinder 4, cooperates with groove 2 on the chassis, locks the vertical shaft chassis.Electric furnace shaft is in the reinforced process of material basket, 70 tons of steel scraps impact the vertical shaft water-cooling wall from 14 meters high-altitude, produce very big component along the vertical shaft direct of travel, vertical shaft lock lock mode originally is telescopic, lock core relies on 8 locating pieces 3 to guarantee axiality with the lock frame, lock circle frame is too thin, even if the both sides vertical shaft is locked into the position, in fact the tapered end on lock core and the vertical shaft also is gapped, in the impact process that feeds in raw material repeatedly, the gap is by bigger and bigger, till the weld seam of latch frame was lost efficacy by drawing crack.Vertical shaft lock can not effectively lock vertical shaft, and latch frame is torn under impact force action on the contrary, and the forfeiture locking function also causes the big bell displacement of vertical shaft, thrusts electrode, damage equipment and cause danger easily.
Therefore, provide a kind of Electric furnace shaft locking device simple in structure, firm, safe and reliable, that the life-span is long real for necessary.
[summary of the invention]
The purpose of this utility model is to provide a kind of simple in structure, firm, safe and reliable, Electric furnace shaft locking device that the life-span is long.
For realizing the utility model purpose, provide following technical scheme:
The utility model Electric furnace shaft locking device, it comprises the skewback tapered end that is arranged on silo bottom, is arranged on the tie-bar that is connected with hydraulic cylinder in the latch frame, this tie-bar can cooperate with the inclined-plane wedging of skewback tapered end.
This skewback tapered end is arranged on the side of silo bottom, and hydraulic cylinder is horizontally installed in the latch frame, and this tie-bar is by Driven by Hydraulic Cylinder, and oblique setting, cooperates with the inclined-plane wedging of skewback tapered end.Such structure has reduced the lateral stressed impact of latch frame.Vertical shaft locking bit mode is by the telescopic inclined-plane wedging type of changing into up and down, the tapered end of silo bottom is made a skewback, in vertical shaft when locking, make tie-bar and inclined-plane wedging in the latch frame by the hydraulic cylinder pulling force, with stressed decomposition, the impulsive force that when coupling mechanism force that the inclined-plane produces is enough to resist the steel scrap tenesmus vertical shaft water-cooling wall is produced, thus make mechanism's locking reliable.
Simultaneously, can change the common hydraulic cylinder that originally used into the water-cooled hydraulic cylinder, stopped because under the worst hot case common hydraulic cylinder in let out phenomenon, thereby guaranteed that vertical shaft locking device hydraulic system pressure keeps constant.
The contrast prior art the utlity model has following advantage:
The utility model Electric furnace shaft locking device structure is simple, by inclined-plane wedging type locking design, with stressed effective decomposition, makes mechanism's locking reliable, has guaranteed the safe and reliable and service life of Electric furnace shaft locking device.

Fig. 1 is the structural representation of existing Electric furnace shaft locking device;
Fig. 2 is the side view of existing Electric furnace shaft locking device;
Fig. 3 is the structural representation of the utility model Electric furnace shaft locking device;
Fig. 4 is the side view of the utility model Electric furnace shaft locking device.
[specific embodiment]
See also Fig. 3 and Fig. 4, the utility model Electric furnace shaft locking device, it comprises the skewback tapered end 5 that is arranged on the silo bottom side, is horizontally installed on the hydraulic cylinder 4 in the latch frame 7, the oblique tie-bar that is connected with hydraulic cylinder 4 that is arranged in the latch frame 7.
This tie-bar 6 is driven by hydraulic cylinder 4, makes the inclined-plane wedging of tie-bar 6 and skewback tapered end 5 in the latch frame 7 during the vertical shaft locking by hydraulic cylinder 4 pulling force.Vertical shaft locking bit mode is by the telescopic inclined-plane wedging type of changing into up and down, such structure has reduced the lateral stressed impact of latch frame, vertical shaft stressed decomposition of when locking is also cushioned, the impulsive force that when coupling mechanism force that the inclined-plane produces is enough to resist the steel scrap tenesmus vertical shaft water-cooling wall is produced, thus make mechanism's locking reliable.
Simultaneously, change the common hydraulic cylinder that originally used into water-cooled hydraulic cylinder 4, stopped because under the worst hot case common hydraulic cylinder in let out phenomenon, thereby guaranteed that vertical shaft locking device hydraulic system pressure keeps constant.
The above only is preferred embodiment of the present utility model, and protection domain of the present utility model is not limited thereto, and anyly all belongs within the utility model protection domain based on the equivalent transformation on the technical solutions of the utility model.
