Description
Technical field
The utility model relates to a kind of pit kiln, relates in particular to a kind of coke oven door cutting edge and repairs frock.
Background technology
Coke oven is used extensively in coking industry at present, and coke oven door is the very important furnace retaining equipment of coke oven.The fire door of coke oven generally all adopts iron to iron self-sealing, and the cutter front cover precision-fit of fire door knife edge and firedoor frame, seals coking furnace shaft.The tightness of fire door is burned with anger to preventing from smoldering and stove frame, furnace stay distortion, inefficacy have substantial connection.Whether fire door knife edge is intact, very large with the relation of burning with anger of preventing from smoldering.In process of production, because fire door is seted out frequently, and contact with atmosphere, temperature variation is violent, so easily bending damage of fire door knife edge.For this reason, in coke oven production system, be all provided with fire door service station, loop according to plan fire door repairs.Traditional fire door knife edge repair method is by after the artificial excision of the knife-edge of distortion, then new knife-edge is welded up.The rehabilitation cost of this kind of knife-edge restorative procedure is high, and the distortion knife-edge cutting down cannot recycle, and can only scrap, and the new knife-edge strength of joint after welding is not high, is easy to produce secondary deformation.
Utility model content
The technical assignment of technical problem to be solved in the utility model and proposition is that prior art is improved, and provides a kind of coke oven door cutting edge to repair frock, solves in current technology fire door knife edge maintenance cost high, the problem that frequency of maintenance is high.
For solving above technical problem, the technical solution of the utility model is:
A kind of coke oven door cutting edge is repaired frock, comprise flat board, calibration bars and standing groove, standing groove is fixed on flat board, calibration bars are connected on flat board by securing gear, and by regulating the gap between the adjustable calibration bars of securing gear and flat board, by flat board, calibration bars and standing groove three, form one and proofread and correct chamber, knife-edge is inserted into be proofreaied and correct in chamber, regulates securing gear to make calibration bars compress knife-edge and proofreaies and correct its deformation quantity.By regulating securing gear that the gap between calibration bars and flat board is shortened gradually, to producing the knife-edge of deformation, exert pressure, until knife-edge is flattened on flat board, its deformation quantity is proofreaied and correct, knife-edge recovers straight state.This kind of bearing calibration is simple, and knife-edge is not implemented to destructive replacing, has guaranteed the structural strength of knife-edge, has extended the work-ing life of knife-edge, is not prone to the secondary deformation while changing knife-edge as welding.And can repair by this coke oven door cutting edge that frock is repeated multiple times proofreaies and correct reparation to knife-edge, greatly extend the work-ing life of knife-edge, effectively reduce the maintenance cost of frequent replacing knife-edge, reduce the cost depletions in production process.
Further, described securing gear adopts the mode of bolted, and simple and practical, cost of manufacture is low, rotation adjusting bolt is the gap between adjustable calibration bars and flat board, the structural strength of bolt is high, and screw thread is with auto-lock function, guarantees fastening intensity, avoid resilience, can effectively guarantee the planeness quality that knife-edge is proofreaied and correct, make the knife-edge after proofreading and correct can reach good stopping property, prevent from that coke oven from smoldering to burn with anger the personnel that cause are injured.
Further, described calibration bars are arranged in a line and are formed by a plurality of independently compressing members, each compressing member have separately a securing gear can be local the application of force proofread and correct the deformation quantity of knife-edge.When knife-edge only has local generation deformation bending, only need to regulate near the several compressing member knife-edges of knife-edge generation deformation place to exert pressure and flattened on flat board, proofread and correct the Bending Deformation of blade.Adopt this kind of mode at timing without by the compressing member locking on whole calibration bars, save manpower and man-hour and reduce the working strength of proofreading and correct, also saved the manufacturing cost of the material reduction frock of making calibration bars simultaneously, thereby avoid making knife-edge in the engineering of proofreading and correct produce deformation with calibration bars because rectangular calibration bars itself have produced deformation, finally do not reach correction knife-edge and recover straight effect.
Further, on described platform, be also provided with set screw for fixed and repaired frock, avoid in the process of proofreading and correct coke oven door cutting edge to repair frock and be subjected to displacement that to cause securing gear to lock not tight, reduce the effect of proofreading and correct.
Compared with prior art, the utility model advantage is:
Coke oven door cutting edge described in the utility model is repaired frock the knife-edge that produces deformation is pressed on straight flat board, its deformation is restored and reaches straight state, guarantee the stopping property of coke oven door, this reparation frock is not implemented destructive replacing to knife-edge, correction repairing effect is better, guaranteed the structural strength of knife-edge, extended the work-ing life of knife-edge, and can repair by this coke oven door cutting edge that frock is repeated multiple times proofreaies and correct reparation to knife-edge, greatly reduce the maintenance cost that replacing knife-edge produces; The utility model is simple in structure, easy to use, is easy to realize, and low cost of manufacture, enhances productivity, and coke oven is produced and stablized long-term operation, reaches the good result of energy-saving and emission-reduction.
