Abstract
The invention relates to a coke oven door spring blade edge repair device which comprises a platform, wherein supporting strips are welded and fixed to the platform; pressing plates are arranged on the platform and are connected with the platform through long bolts; spring blade edges are tightly pressed below the pressing plates and are locked on the supporting strips through locking devices; each locking device comprises a fastener and two locking bolts; the every two locking bolts are welded on the two sides of each fastener; the locking bolts are cooperatively used with the fasteners and have fixing and clamping effects. According to the repair device, effective parts of a few waste spring blade edges can be re-assembled into a spring blade edge capable of being normally used, so that the waste spring blade edges are recycled and the production cost is reduced.
Description
Technical field
The invention belongs to coking equipment technology prosthetic device technical field, relate to a kind of coke oven door spring knife-edge repair apparatus.
Background technology
Fire door knife edge is the significant points making fire door tight, is pressed on firedoor frame cuts off contacting of coking chamber and ambient atmosphere by knife-edge.Spring knife-edge angle steel and Steel Spring Plate are made, and by being bolted on fire door muscle, knife-edge is pressed on firedoor frame by spring jackscrew, the pressure of spring jackscrew can regulate with push bolt, automatically can regulate knife-edge owing to having, the advantage of convenient management, spring knife-edge is widely adopted.In coking production process, the residual substance such as coke tar refuse and coke powder can accumulate inside knife-edge.When these residual substances amass thick, knife-edge is easy to extrusion.In addition, when plucking, hanging fire door, fire door knife edge comparatively easily collides with coking chamber, knife-edge is out of shape, damage.Traditional spring knife-edge repair method utilizes to be arranged on the fire door service station at coke oven two ends, after first the fire door to be repaired be placed on fire door repairing rack being positioned over level attitude with windlass, corrects positions such as knife-edge distortion, damage, sealing-offs, repair welding.Because between angle steel and Steel Spring Plate being the connection of two-sided full weld, when spring knife-edge places level, its upper surface weld seam upward, repair welding repair procedures more for convenience, but when carrying out repair welding to its lower surface weld seam and repairing, due to weld seam down and operating space is little and cannot weld, push bolt must be unclamped, spring knife-edge is taken off from fire door, after upset one side, repair welding repairing could be carried out again.In this process, what lose push bolt because of spring knife-edge fixes to clamp effect, is heated and very easily deforms, be also difficult to take effective means to correct, do not reach good repairing effect in welding process.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of coke oven door spring knife-edge repair apparatus improving operating environment, improve repairing quality, reduce production cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of coke oven door spring knife-edge repair apparatus, include a platform, be welded with support bar on the platform, be provided with pressing plate on the platform, this pressing plate is connected with platform by thru-bolt, compress below pressing plate and have spring knife-edge, this spring knife-edge is then locked on support bar by locking latches, described locking latches is made up of a fastener and two securing bolts, securing bolt is welded on fastener both sides, with fastener with the use of, work the effect of fixing to clamp.
Described platform is made by rectangle steel plate, and bottom is supported by four steel columns.
Described support bar material is solid steel bar, and is weldingly fixed on platform according to the size of spring knife-edge, mainly plays a supportive role, to guarantee that the spring knife-edge taken off from fire door can smoothly be placed on platform.
Described pressing plate is connected with platform by thru-bolt.
Described fastener is provided with adjustment hole, reduces and is fixed on outside support bar through adjustment hole and platform steel plate body by bolt.
Described locking latches is respectively arranged in a line along land lengths, width, and the locking latches quantity along berm width direction is slightly few.
The invention has the beneficial effects as follows: existing fire door service station is all located at coke oven both sides end stand, operating environment high temperature and dust is larger; Repair apparatus of the present invention, without the need to being located at coke oven region, significantly improves the work situation of fire door service station operative employee; Adopt this repair apparatus can effectively solve when repairing spring knife-edge lower surface, spring knife-edge lose fix to clamp after be heated and very easily deform and the extremely difficult problem corrected, improve the repairing quality of spring knife-edge; Very smooth for spring knife-edge can be fixed on platform by this repair apparatus simultaneously, can play again the effect correcting fire door knife edge, improve the stopping property of fire door knife edge while facilitating spring knife-edge to repair; This repair apparatus can utilize the effective member of several waste and old spring knife-edges, be again assembled into the spring knife-edge that a pair can normally use, and the waste and old spring knife-edge of recycle, reduces production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is embodiments of the invention schematic diagram.
In figure: 1-platform, 2-support bar, 3-securing bolt, 4-fastener, 5-pressing plate, 6-spring knife-edge, 7-thru-bolt.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
See Fig. 1 and Fig. 2, a kind of coke oven door spring knife-edge 6 repair apparatus, include a platform 1, this platform 1 is welded with support bar 2, this platform 1 is provided with pressing plate 5, this pressing plate 5 is connected with platform 1 by thru-bolt 7, compress below pressing plate 5 and have spring knife-edge 6, this spring knife-edge 6 is locked on support bar 2 by locking latches, described locking latches is made up of a fastener 4 and two securing bolts 3, securing bolt 3 is welded on fastener 4 both sides, with fastener 4 with the use of, work the effect of fixing to clamp.
Described platform 1 is made by rectangle steel plate, and bottom is supported by four steel columns.
Described support bar 2 material is solid steel bar, and is welded and fixed on the platform 1 according to the size of spring knife-edge 6, mainly plays a supportive role, to guarantee that the spring knife-edge 6 taken off from fire door can smoothly be placed on the platform 1.
Described pressing plate 5 is connected with platform 1 by thru-bolt 7.
Described fastener 4 is provided with adjustment hole, reduces and is fixed on outside support bar 2 through adjustment hole and platform 1 steel plate body by bolt.
Described locking latches is respectively arranged in a line along platform 1 length, width, and the locking latches quantity along platform 1 width is slightly few.
When repairing spring knife-edge 6, be placed horizontally on support bar 2 by spring knife-edge 6 upper surface weld seam direction upward, first use fastener 4 by its fastening, then with securing bolt 3, spring knife-edge 6 is locked, finally again by regulating thru-bolt 7 pressing plate 5 to be compressed by spring knife-edge 6.
The residues such as the coke tar refuse, coke powder and the graphite that accumulate spring knife-edge 6 upper surface to be repaired are eliminated clean, find out knife-edge and damage and weld seam sealing-off position, and perform mark, and then repair welding, polishing, correction are carried out in pointwise.
