Problems solved by technology

Due to the heavy weight of the blowpipe 3, when the hoist is used to closely contact it with the flange of the corrugated compensator 1, the final fastening connection is to tighten the eight wedges completely by manpower, which is laborious for maintenance, and the labor intensity of the workers is high. There are many people working, and the wind break time is long; in addition, the workers who are responsible for tightening the wedge often touch the workpiece next to them when swinging the sledgehammer, which will damage their hands and feet, and pose a great safety hazard

Embodiment Construction

[0015] The present invention will be further described below in conjunction with the drawings and embodiments.

[0016] See figure 2 , A quick disassembly and assembly of blast furnace blowpipe tightening diagonal wedge tool, including a tool body made of a steel plate with a thickness of 30mm, which is integrally cut according to the size. The upper and lower ends of the tool body are integrated and connected with two clamps in the same direction. Code 5, a jack 6 is mounted on the bottom card code 5, and the jack 6 can clamp the connecting flange 2 between the card code 5 and the jack 6 when the blowpipe 3 is connected with the corrugated compensator 1 and the flange 2.

[0017] See image 3 , The application process of the above-mentioned quick disassembly and assembly blast furnace blowpipe tightening diagonal wedge tool is:

[0018] When disassembling the blowpipe 3, first use a 2T hand chain hoist to tighten the blowpipe 3 by using the pre-welded support on the blast furnace s...

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 [0001] The invention belongs to the technical field of disassembly and assembly devices for blast furnace blowpipes, and relates to a quick disassembly and assembly of blast furnace blowpipe tightening wedge tools and a use method thereof. Background technique [0002] see figure 1 , after the blast furnace tuyere small cover 4 is burnt, the blowpipe 3 must be removed to replace the small cover 4. Due to the limitation of the design of the blast furnace tuyere device, the pipes and supports between each other are densely distributed, and the operating site is narrow, which brings great difficulties to the current disassembly operation. with great difficulty; see figure 1 At present, the process of dismantling the blowpipe 3 is: use a 2T hand chain hoist to tighten the blowpipe 3 by using the pre-welded support on the blast furnace shell and the blowpipe 3; use a sledgehammer to connect the blowpipe 3 and the corrugated compensator 1 one by one The oblique w...
