Description
Technical field
The utility model relates to a kind of electric block track structure, relates in particular to the movable electric block track of a kind of continuous casting, and tandem rolling copper rod job shop shaft furnace maintenance lifting.
Background technology
In the continuous casting, and tandem rolling copper rod manufacturing enterprise of widespread use, shaft furnace is for one of key equipment of melting copper raw material, uses more and more.Must be with fire brick and refractory material brickwork before the normal work of shaft furnace, and electrolysis copper coin need to be piled to fold in order to blow-on in burner hearth and use.In shaft furnace normal course of operation, shaft furnace mouth can not have suspension, prevents from coming off entering copper liquid in stove and affect liquid and melt the degree of purity of copper.Shaft furnace periodic inspection is to guarantee that shaft furnace is in good working order Main Means.In the cycle of operations of shaft furnace, for adapting to the manufacturing technique requirent of fusing shaft furnace brickwork and periodic inspection, must consider increases the hoist tool of electric block as fire brick and electrolysis copper coin is installed in fire door central authorities, enhances productivity.
Shaft furnace is vertical founding furnace, high approximately 20 meters of shaft, there is the square fire door of approximately 2 × 2 meters at the shaft furnace wall of approximately 18 meters of height, shaft furnace fire door top is provided with chimney and the exhaust fume collecting hood of diameter 1.8m, high approximately 10 meters of chimney, the most about 3 meters of shaft furnace bottom furnace diameter, reduces 2.5 meters of fire door place diameters along with highly increasing shaft diameter.Fire door is shaft furnace brickwork, maintenance, the reinforced entrance of production, and due to space constraint, conventional hoist tool can not be applicable to this special environment.In some old continuous casting, and tandem rolling copper rod manufacturing enterprises, there is no special electric block track, traditional method is to be welded on fire door and the inboard wall of furnace body to fire door just with a H shaped steel temporarily, as interim electric block track, cancels temporary track after using again.Although this way can realize the hoisting function of electric block, operational space is narrow and small, and installation difficulty is large, and installation personnel lacks safety control, and track girder installation strength and precision are low, and electric block operation stability is poor.Possess mobilizable function in view of above reason realizes hoist tool, while normally production, electric block track can exit from fusing shaft furnace mouth, and when maintenance, electric block track can slide into fire door central authorities.Effectively alleviating the labour intensity that operating personal track is installed, is to allow operate hommization more, makes the more secure inexorable trend of operating personal and device security.This new construction can increase handling stability, work more flexible, and management maintenance is easy.Only increase input on a small quantity, change track structure and just can realize.The practicality of this hoist tool is through practical application, and proving effect is obviously better than traditional method.Can promote in of the same type and similar type project.
Utility model content
The purpose of this utility model is to provide a kind of shaft furnace maintenance hoist tool, uses flexibly, is not subject to on-the-spot complex work environmental restraint, guarantees normally to bring into play the hoisting function of electric block.
A kind of shaft furnace maintenance hoist tool, it is characterized in that, comprise the Composite Double track being formed by trapped orbit beam and movable track girder, guide wheel device, electric block and be welded on the fixed bearing on the inwall that faces shaft furnace fire door, described trapped orbit beam and movable track girder are all selected H shaped steel, described trapped orbit beam is fixed on shaft furnace fire door dead ahead, described electric block is arranged on movable track girder, on described movable track girder, be welded with paired web, described guide wheel device is arranged on paired web center and is fixed in the groove of the track girder left and right sides, described movable track girder is overlapped on trapped orbit beam by guide wheel device and fixed bearing.
Further, for strengthening the stability of movable track, at the guide plate of shaft furnace fire door entrance, described guide plate hangs movable track girder with bolt connecting mode.
Further, also comprise and be arranged on two actuating devices on track girder.
When need of work, track slides into fire door middle position by guide wheel device, can complete the handling work in fusing shaft furnace; While needs, track slides into fire door scope in addition by guide wheel device again, does not affect normal production, makes the use of electric block more flexible.
The utility model has the advantage of:
1, the single track concept of electric block breaking traditions, the Composite Double track that creative use is special, the middle guide wheel device that adopts connects.
2, not limited by working environment, mode of operation is more flexible, can, according to the length of actual conditions advancing the track, give full play to handling resource, and space availability ratio is high, flexible working mode.
3, be particularly useful for narrow space and the lifting large region of the discrepancy in elevation.
4, guide wheel device makes orbiting motion steady, and handling precision is high, and handling efficiency is high, and reliability is strong.
5, can be according to actual conditions appropriate design guide wheel device installation site, install simple, easy to operate, safeguard easily.
6, the cost of increasing input is few, saves the input of human and material resources.
