Abstract
The utility model relates to a tooling for replacing a temperature measuring device of a blast furnace and belongs to the technical field of metallurgy. The technical scheme includes that the tooling comprises a hydraulic oil cylinder, a traction pipe, an oil cylinder support and a triangular rolling frame, the traction pipe is disposed on the triangular rolling frame, one end of the traction pipe is coaxially connected with a temperature measuring device to be replaced, an oil cylinder connecting frame is arranged at the other end of the traction pipe, the hydraulic oil cylinder is arranged above the traction pipe and is parallel to the same, a shell of the hydraulic oil cylinder is fixed on the oil cylinder support and hinged with a blast furnace body, and a piston rod of the hydraulic oil cylinder is hinged with the oil cylinder connecting frame on the traction pipe. The temperature measuring device is pulled to axially move by the hydraulic oil cylinder, is pulled out from a mounting sleeve on the blast furnace body or is inserted into a sleeve, and thereby the temperature measuring device can be quickly mounted and demounted. Labor intensity of maintenance operators is greatly reduced, maintenance efficiency of the temperature measuring device is improved and maintenance cost is reduced. Besides, the tooling has the advantages of simple structure, convenience in operation, safety and the like.
Description
Technical field
The utility model relates to a kind of frock for changing large blast furnace furnace roof cross temperature measurer, belongs to metallurgical technology field.
Background technology
In recent years, along with the continuous increase of furnace volume, the maintenance of temperature measuring equipment and replacing difficulty are increasing, for example 2500 m
3Blast furnace has the temperature measuring equipment of 4 columns, and they evenly distribute around blast furnace throat, is cross and tilts to install (being called cross temperature measurer).Each temperature measuring equipment overall length 5400mm, the thickest position is Φ 300mm, gross weight reaches 5 tons, changes the manpower that temperature measuring equipment involves more at every turn, expends time in longer, changes a cross temperature measurer and needs about 10 hours, has greatly improved the cost of overhaul of blast furnace.Therefore, how the quick-replaceable blast furnace cross temperature measuring equipment just becomes the present problem that faces of relevant technologies personnel.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of frock for changing Thermo detector for blast furnace is provided, and to improve the overhaul efficiency of Thermo detector for blast furnace, reduces the cost of overhaul.
Problem described in the utility model is realized by following technical scheme:
A kind of frock for changing Thermo detector for blast furnace, it comprises that hydraulic jack, traction tube, cylinder bracket and triangle roll frame, described traction tube is placed on triangle and rolls on the frame, the one end is connected with temperature measuring equipment to be replaced is coaxial, the other end is provided with the oil cylinder link, described hydraulic jack is positioned at traction tube top and parallel with traction tube, and its shell is fixed on the cylinder bracket and is hinged with the body of heater of blast furnace, and the piston rod of hydraulic jack and the oil cylinder link on the traction tube are hinged.
Above-mentioned frock for changing Thermo detector for blast furnace, described traction tube adopts seamless pipe.
Above-mentioned frock for changing Thermo detector for blast furnace, the end that described traction tube and temperature measuring equipment join is provided with the welding muscle.
The utility model utilizes oil cylinder to drag temperature measuring equipment and moves along its axis, to extract out the mounting sleeve of temperature measuring equipment from body of heater or temperature measuring equipment be inserted sleeve pipe, thereby realize the fast assembling-disassembling of temperature measuring equipment, this device greatly reduces maintainer's labour intensity, improve the overhaul efficiency of temperature measuring equipment, reduced the cost of overhaul.In addition, the utility model also has the advantages such as simple in structure, easy to operate, safe.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Each label is among the figure: 1, temperature measuring equipment; 2, body of heater; 3, hydraulic jack; 4, oil cylinder link; 5, traction tube; 6, triangle rolls frame; 7, platform; 8, cylinder bracket; 9, welding muscle; 10, sleeve pipe.
The specific embodiment
Referring to Fig. 1, the utility model comprises that hydraulic jack 3, cylinder bracket 8, traction tube 5 and triangle roll frame 6, traction tube 5 is connected with the piston rod of hydraulic jack 3 by the oil cylinder link 4 of its end, during hydraulic jack 3 work, its piston rod tractive force that produces of stretching, contract acts on the temperature measuring equipment 1 by oil cylinder link 4 and traction tube 5, makes temperature measuring equipment 1 roll frame 6 along triangle and at the uniform velocity shifts out or slip into body of heater 2 by certain angle.
Frock making:
Facts have proved, adopt this frock to remove a cross temperature measurer, and with new cross temperature measurer spare part installation in position, the time spent is 3 hours, maintainer's configuration reduces by half, and has greatly improved overhaul efficiency, has shortened the blast furnace periodical repair time, has reduced the cost of overhaul.
Temperature measuring equipment 1 method for dismounting:
The first, break connecting bolt and welding position between temperature measuring equipment 1 and body of heater 2 flanges with gas cutting; The second, with jack lived in the temperature measuring equipment top; Three, by Fig. 1 hydraulic jack 3 and traction tube 5 are connected, open the petrol station oil pump, primer fluid compressing cylinder 3 makes temperature measuring equipment 1 roll frame 6 along triangle and skids off body of heater 2; Four, oil cylinder and oil cylinder link 4 are taken apart, primer fluid compressing cylinder 3, the cylinder piston rod retracted for clearance is closed oil cylinder; Five, with guide chain and overhead traveling crane thermometric is moved apart the scene; Six, remove the replacing frock of temperature measuring equipment.
