The hoisting device is simple in structure and strong in practicability; when the hoisting device is used for hoisting water pipe flanges, the hoisting device is fully adhered to the lugs at the roots of the water pipe flanges through a semicircular clamping slot and the support plates which are connected with the semicircular clamping slot so as to ensure that flange connection end faces are located accurately when the flanges are hoisted; and through the hoisting device, mounting and fastening of fastening parts are facilitated.
Description
Technical field
The utility model relates to hanging device technical field, particularly a kind of hanging apparatus.
Background technology
Converter oxygen gun plays vital effect in converter steelmaking production process, is undertaking to the task of molten steel bath lancing gas in converter, completes oxygen blowing in molten steel intensification decarbonization process.Can also realize the slag splashing to body of heater by high pressure nitrogen blowing simultaneously.Oxygen gun cooling water pipe Main Function is to carry water coolant to reduce the temperature of rifle body to oxygen gun body, and oxygen gun body is connected with water inlet pipe with rising pipe realizes rifle body circulating cooling function.The size of body of heater, oxygen rifle and oxygen gun cooling water pipe is conventionally larger, and quality is also heavier, and the replacing installation exercise of water-cooled tube is also relatively difficult, needs overhead traveling crane lifting coordinating operation.
On Converter Oxygen Lance In Steelmaking Plant water-cooled tube is owing to being subject to that size is large, quality is heavier, installation site is narrow and small and the restriction of the factor such as the bad lifting of water pipe connecting flange structure, and it is more difficult that its water-cooled tube is changed installation exercise.In the replacing installation process of oxygen rifle water pipe, the connecting end surface of water pipe flange will keep level, and suitable in the face of position is accurate, distance is located with oxygen gun body flanged ends, smoothly mounting flange joint bolt.When changing installation water pipe, directly with steel cable, be wrapped in flange root lifting water pipe in the past, while lifting with steel cable, can not guarantee flanged ends face maintenance level, can not make the flange of water pipe and the good contraposition of flange of oxygen gun body and coordinate, thereby the contraposition installation work that causes water pipe flange bolt difficulty very, causes upkeep operation overlong time.Water pipe installs with after for some time, and flange connections also has seepy question generation sometimes, can have influence on the normal production of converter when serious.
Utility model content
Technical problem to be solved in the utility model is to provide and a kind ofly can maintains flange connection surface level, the hanging apparatus being located to connect.
For solving the problems of the technologies described above, the utility model provides a kind of hanging apparatus, for flange, lifts; Described hanging apparatus comprises: draw-in groove, back up pad and hanger; Described draw-in groove is semicircle ring structure; The two ends of described draw-in groove arrange respectively back up pad; Hanger is set respectively in described back up pad; Described draw-in groove and described back up pad support described flange by the flange laminating with described flange.
Further, also comprise lug; Described lug is a pair of, is placed in respectively on the outer side wall of back up pad; Described hanger is placed in respectively on described lug.
Further, chamfering is offered at the edge of described draw-in groove and described back up pad.
Further, the binding face of the flange of described draw-in groove and described back up pad and described flange is laid rubber pad.
The hanging apparatus that the utility model provides, simple in structure, practical; Be used for lifting water pipe flange.By semicircle draw-in groove and the back up pad that the is attached thereto flange of water pipe flange root of fitting fully, thereby while guaranteeing flange lifting, flanged ends face keeps level, accurate location, and the installation of being convenient to fastening piece is fastening.
Accompanying drawing explanation
Fig. 1 is the front view of flange;
Fig. 2 is the vertical view of flange;
The structural representation of the hanging apparatus that Fig. 3 provides for the utility model embodiment;
Wherein, 1-draw-in groove, 2-back up pad, 3-hanger, 4-lug, 5-flange, 6-flange root.
Embodiment
Referring to Fig. 3, a kind of hanging apparatus that the utility model embodiment provides, comprising: draw-in groove 1, back up pad 2 and hanger 3; Draw-in groove 1 is semicircle ring structure, for coordinating the tubular structure of flange, blocks flanged pipe root; The two ends of draw-in groove 1 arrange respectively back up pad 2, and back up pad 2, for being engaged in flange hoisting process with draw-in groove 1, is carried the deadweight of flange; Hanger 3 is set in back up pad 2, and hanger 3 is for connecting stay cord at hoisting process, by weight handling equipment integral hoisting.
Referring to Fig. 1, Fig. 2 and Fig. 3, when this device is used, flange root 6 is embedded in the hanging apparatus of overall U-shaped, the outer wall laminating of the inwall of draw-in groove 1 and flange root 6, draw-in groove 1 and back up pad 2 are fitted with the lower surface of flange 5, thereby guarantee that the connecting end surface of flange is in level, the location of Optimal Hoisting device.When carrying out lifting operation, stay cord, through after a side hanger, is close to the outer wall of flange root 6, passing opposite side hanger; By stay cord and draw-in groove 1, flange root 6 is surrounded fastening.After confirming hanging apparatus and flange 5 laminatings closely, stay cord is connected to weight handling equipment and carry out lifting.
In order to prevent in hoisting process, the flange 5 of flange, because vibrations and hanger 3 produce extruding or friction damage flange 5, even causes its influence of crust deformation normally to use; Preferably, lug 4 is set respectively on the outer side wall of supported on both sides plate, hanger 3 is separately fixed on both sides lug 4, between flange 5 and hanger 3, reserve enough spaces.
Flange is as tubing interconnecting piece, and in order to prevent its corrosion, surface is all provided with electrolytic coating, can be good at preventing the corrosion corrosion of environment; But it is not high for friction, to scratch resistance; Therefore, in order to prevent that contact friction from scratching, preferred, chamfering is offered respectively at the draw-in groove 1 of hanging apparatus and the edge of back up pad 2, avoids in hoisting process, and the edge of hanging apparatus scratches flange.
In view of hanging apparatus and flange 5 laminatings, in order to prevent the deadweight due to flange, on the flange 5 of flange, leave indenture or produce deformation, affect the fastening effect of flange; Preferably, on the binding face of draw-in groove 1 and back up pad 2 and flange, lay rubber pad, stressed to cushion, protect to greatest extent flange.
The hanging apparatus that the utility model provides, simple in structure, practical; Be used for lifting water pipe flange.By semicircle draw-in groove and the back up pad that the is attached thereto flange of water pipe flange root of fitting fully, thereby while guaranteeing flange lifting, flanged ends face keeps level, accurate location, and the installation of being convenient to fastening piece is fastening.In addition, the electrolytic coating that chamfering avoids scratching flange is offered at the edge of hanging apparatus, has reduced the damage of lifting operation to flange; On the contact surface of hanging apparatus and flange, lay rubber pad for cushioning contact pressure, avoid the contact deformation of flange, thereby well protect flange, reduce the impact of lifting operation on its sealing effectiveness.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
