Abstract
The invention relates to a tool for quick disassembly and assembly of a blast furnace blowpipe and tight beating of tapered wedges. The tool includes a tool body; the upper end and the lower end of the tool body are respectively connected with two same-direction clamps in an integration mode; a jack is mounted on the bottom clamp; the jack can press against a connection flange tightly when a blowpipe and the corrugated compensator connection flange are clampingly connected between the clamp and the jack. The tool has the characteristics of reasonable design structure and high efficiency, can avoid a phenomenon that a flange joint has wind leakage because of uneven force application when manpower is used for tight beating of the tapered wedges, avoids a rework problem, can be applicable to location, connection and tight locking of various flanges, and has relatively good popularization and application values.
Description
Technical field
The invention belongs to the attaching/detaching apparatus technical field of blast furnace blowpipe, relate to the urgent wedge instrument of a kind of fast assembling-disassembling blast furnace blowpipe and using method thereof.
Background technology
Referring to Fig. 1, after blast furnace tuyere small sleeve 4 scaling loss, must remove blowpipe 3, could change little cover 4, due to the limitation of blast-furnace tuyere device design, pipeline each other, support gather, and operation field is narrow, brings very large difficulty to present dismounting operation; Referring to Fig. 1, the process that we remove blowpipe 3 is at present: with a 2T chain block, utilize the bearing welding in advance on blast furnace shell and blowpipe 3 by blowpipe 3 tensions; With sledgehammer, one by one the wedge on eight fore locks on the joint flange 2 of blowpipe 3 and FlexbleJoint 1 is beaten de-ly, unloaded fore lock; Remove blowpipe 3 take-up device screw rods; After utilizing fork truck that blowpipe 3 is lifted, loosen cucurbit; Fork truck shifts out operation field by blowpipe 3; The process of returning dress blowpipe 3 is: with fork truck, lift blowpipe 3, it is sent in air port, the blunt end of blowpipe 3 withstands on the conical surface of tuyere small sleeve 4 after cleaning, the bend pipe end of blowpipe 3 is connected by flange with one end of FlexbleJoint 1, adjust behind location, put into metal and asbestos gasket, utilize the bearing welding in advance on blast furnace shell and blowpipe 3 by blowpipe 3 tensions with a 2T chain block, fork truck exits; In position, eight wedge holes, pack fore lock into, with the even urgent wedge of sledgehammer, adjust upper and lower take-up device screw rod, remove cucurbit and complete installation.Because blowpipe 3 weight are large, when using cucurbit by the flange close contact of it and FlexbleJoint 1, last being fastenedly connected is by manpower, eight wedges are urgent completely, maintenance effort, workman's labour intensity is higher, and the personnel that drop into operation are also many, and the damping down time is longer; In addition, be responsible for the workman of urgent wedge, while brandishing sledgehammer through being everlasting, encounter the workpiece on side, damage trick, potential safety hazard is larger.
Summary of the invention
For overcoming above-mentioned technical disadvantages, the invention provides the urgent wedge instrument of a kind of fast assembling-disassembling blast furnace blowpipe and using method thereof, the steel plate that it is 30mm by a thickness is made by size Whole blanking, born greatly steel plate suffered tension force when screw block holds out against two flanges, guarantee urgent wedge, there is design light and handy, simple to operate, the feature of safe ready.
The present invention solves the technological method that its technical problem adopts: the urgent wedge instrument of a kind of fast assembling-disassembling blast furnace blowpipe, comprise tool body, at the upper and lower two ends of tool body, integrated two of being connected with in the same way block code respectively, on the card code of bottom, be mounted with a screw block, screw block can be between card code and screw block holds out against joint flange when clamping blowpipe and FlexbleJoint joint flange.
The urgent wedge instrument of above-mentioned fast assembling-disassembling blast furnace blowpipe, its application process is:
During dismounting blowpipe, first use a 2T chain block, utilize the bearing welding in advance on blast furnace shell and blowpipe that blowpipe is strained; Then a card code of this instrument is placed on the joint flange of blowpipe and FlexbleJoint, uses a screw block that joint flange is held out against; Then with sledgehammer, one by one the wedge on eight fore locks on the joint flange of blowpipe and FlexbleJoint is beaten de-ly, unloaded fore lock; Finally remove blowpipe take-up device screw rod, loosen cucurbit after utilizing fork truck that blowpipe is lifted, fork truck shifts out operation field by blowpipe;
While returning dress blowpipe, first with fork truck, lift blowpipe, it is sent in air port, the blunt end of blowpipe withstands on the conical surface of tuyere small sleeve after cleaning, and the bend pipe end of blowpipe is connected by flange with one end of FlexbleJoint; Adjust behind location, put into metal and asbestos gasket, with a 2T chain block, utilize the bearing welding in advance on blast furnace shell and blowpipe that blowpipe is strained, fork truck exits; In position, eight wedge holes, pack fore lock into again, two card codes of this instrument are placed on the joint flange of blowpipe and FlexbleJoint, use two screw block that joint flange is held out against; Finally, with the even urgent wedge of sledgehammer, adjust upper and lower take-up device, remove cucurbit.
The steel plate that described tool body is 30mm by a thickness is made by size Whole blanking.
The invention has the beneficial effects as follows: thus dress be dismantled and be returned to this device can by blowpipe by the joint flange of clamping blast-furnace tuyere device, and utilize after screw block clamping flange, reduce the number of times that manpower hits wedge, reduce the risk of safety injury, improved operating efficiency, by blowpipe of original dismounting, to shorten to 70 minutes with 90 minutes, reduced the damping down time, also reduce workman's labour intensity simultaneously, reduce the operating personnel who drops into, there is project organization reasonable, efficient feature, in the time of can avoiding due to the urgent wedge of manpower, inhomogeneous and the phenomenon that causes flange connections to leak out of size firmly, avoid the problem of doing over again, location applicable to various flanges, connect, locking, there is good application value.
