Abstract
The utility model provides a hydraulic type movable smoke hood lifting device comprising a driving device and a connecting device, wherein the connecting device is used for connecting driving device and a movable smoke hood, and the driving device is a swing type hydraulic cylinder. Because the hydraulic type movable smoke hood lifting device adopts a mechanical type synchronizing mechanism, only one swing type hydraulic cylinder is used as the driving device, and therefore, the hydraulic type movable smoke hood lifting device has high synchronous accuracy, simple structure and low cost.
Description
Technical field
The utility model relates to a kind of movable gas hood lowering or hoisting gear, is specifically related to a kind of fluid pressure type movable gas hood lowering or hoisting gear.
Background technology
Furnace gas after converter mouth ejection, no matter adopt that a kind of purification cooling treatment method, all must be at first through movable gas hood and fixing petticoat pipe, then enter waste heat boiler again or half waste heat boiler utilizes used heat, just enter the purification cooling system afterwards.The movable gas hood lowering or hoisting gear is divided three classes: electronic elevator form, electric screw lifting form, hydraulic-driven form, and wherein the structure of hydraulic-driven form is as described below:
This structure is to adopt the hydraulic cylinder synchronous lifting of four same models, to guarantee the horizontal lifting of movable gas hood.The oil motor of four mechanical connections of synchronous employing of four hydraulic cylinders (tetrad synchronous hydraulic motor) is realized.The shortcoming of this structure is: any motor all can not have identical volumetric efficiency; Hydraulic cylinder also has foozle, perhaps leaks different; These factors will cause four hydraulic cylinders to produce phase difference.This error accumulation then occurs can not guaranteeing the horizontal lifting of movable gas hood than mistake in the elevating movement of movable gas hood to the stroke of hydraulic cylinder.This synchronous error need be recompensed.And to compensate this synchronous error, and must set up compensation circuit in the hydraulic system, for guaranteeing the higher synchronous precision, the class of selected Hydraulic Elements is inevitable higher.And the hydraulic cylinder placement, the baking of being heated is so hydraulic cylinder must have the comparatively complicated solar heat protection measure of structure.These all certainly will cause cost higher.
The utility model content
The purpose of this utility model is to overcome the prior art deficiency, and a kind of synchronization accuracy height, simple in structure, fluid pressure type movable gas hood lowering or hoisting gear that cost is low are provided.
To achieve these goals, the utility model provides a kind of fluid pressure type movable gas hood lowering or hoisting gear, the jockey that comprises drive unit and connect described drive unit and described movable gas hood, and wherein, described drive unit is the swing type hydraulic cylinder.
Preferably, described jockey comprises some chains and connecting plate; Wherein an end of four chains is hinged with four suspension centres of described movable gas hood respectively, and the other end of two chains of homonymy is hinged with an end of a plate after deflecting roller turns in described four chains; One end of other two chains is articulated in the other end of described connecting plate respectively, and the other end of described two chains is fixedly connected on respectively on the corresponding sprocket wheel, and the power transmission shaft of described sprocket wheel is driven by described swing type hydraulic cylinder.
In above-mentioned preferred version, can adopt all or part of alternative chain of steel wire rope, simultaneously according to alternative case, sprocket wheel can replace with reel.
The utility model compared with prior art has the following advantages:
Fluid pressure type movable gas hood lowering or hoisting gear of the present utility model, adopt mechanical connecting devices such as chain (or steel wire rope) and connecting plate that drive unit and lowering or hoisting gear are coupled together, adopt the mechanical type lazy-tongs, and only by a hydraulic cylinder as drive unit, the synchronization accuracy height, hydraulic system is simplified, and need not to adopt syncmotor and corresponding compensation loop.Because the deflecting roller that adopts chain (or steel wire rope) and chain (or steel wire rope) is turned to makes the installation site variation of hydraulic cylinder and away from fire door, makes hydraulic cylinder can adopt the comparatively simple solar heat protection measure of structure.Therefore lowering or hoisting gear of the present utility model had both had the advantage of existing fluid pressure type movable gas hood lowering or hoisting gear and electronic elevator form movable gas hood lowering or hoisting gear, overcome its shortcoming again simultaneously, and connector was simple in structure, made and practicality easy for installation good reliability.
Description of drawings
Fig. 1 is the structural representation of fluid pressure type movable gas hood lowering or hoisting gear of the present utility model;
Fig. 2 is that A shown in Fig. 1 is to view.
The specific embodiment
The utility model provides a kind of fluid pressure type movable gas hood lowering or hoisting gear, the jockey that comprises drive unit and connect described drive unit and described movable gas hood, wherein, described drive unit adopts a swing type hydraulic cylinder, guarantees accurate synchronization accuracy.
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described.
See figures.1.and.2, four suspension centres on the movable gas hood 21 are hinged with an end of four steel chains respectively by four suspension rods and screw-button, two steel chains of homonymy in these four steel chains, after promptly the first steel chain 17 and the second steel chain 18 turn to through directive wheel 13, the other end of the first steel chain 17 and the second steel chain 18 is articulated in an end of a connecting plate 16, only show two steel chains, the first steel chain 17 and the second steel chain 18 of a visible side among the figure, two steel chains of opposite side are not shown, but its structure and connected mode are identical with the first steel chain 17 and the second steel chain 18, promptly also are that the other end is articulated on the connecting plate after deflecting roller turns to.One end of other two steel chains 12 is hinged with the other end of these two connecting plates respectively, the other end of these two steel chains 12 is connected with corresponding sprocket wheel 14 respectively, and the power transmission shaft 15 of these two sprocket wheels 14 is connected with the two ends output shaft of swing type hydraulic cylinder 11 by shaft coupling respectively.
During work, the power transmission shaft that the output shaft of swing type hydraulic cylinder 11 drives sprocket wheel 14 rotates, thereby drive 14 rotations of two sprocket wheels, two sprocket wheels 14 drive two fixedly connected chains 12, two connecting plates 16 and four chains that are connected in movable gas hood, and then by this four chains drive movable gas hood 21 vertical lifting or decline, shown in the four-headed arrow among Fig. 2.Use lowering or hoisting gear of the present utility model can make movable gas hood 21 be parked in petticoat pipe among Fig. 2 back limit inferior position H2 and the petticoat pipe arbitrary position between the limit inferior position H3 of back that descends of rising, top side location when wherein H1 covers for the place of hanging detains exactly.
As preferred embodiment, four chains that link to each other with movable gas hood in the above-mentioned example can adopt steel wire rope to substitute.Further, also other two chains, 12 usefulness steel wire ropes can be substituted, in this case, sprocket wheel 14 can replace with reel.Can certainly only be that other two chains, 12 usefulness steel wire ropes substitute, sprocket wheel 14 usefulness reels replace.The structural similarity of the lowering or hoisting gear in the structure of the lowering or hoisting gear after the replacement and the above-mentioned example, operation principle is identical, no longer repeats at this.
The fluid pressure type movable gas hood lowering or hoisting gear that uses the technical program to realize, manufacturing and installation are all convenient and practical, reliable, easy to maintenance.
