Abstract

The utility model relates to a carbon-oxygen gun manipulator for electric furnace doors, and belongs to a machinery device for various alternate current and direct current arc furnace doors. The utility model is composed of a gun body support frame, a parallel four-connecting rod main arm, a water-cooling pipe, a hydraulic system, etc. The utility model is characterized in that the gun body support frame uses a return head support; the main arm uses a return support seat support; the gun body support frame is designed into a movably detachable support frame; the main arm is a water cooling box-type structure; a water guide pipe and a water return pipe between the main arm and the gun body use the flexible structure, and the connecting part of the water guide pipe and the water return pipe is hermetically connected by a flange. The utility model has the advantages of convenient assembly and disassembly of the gun body, good sealing performance of water-cooling pipe joint, no water leakage, and flexible rotation.

Description

Electric furnace furnace door carbon oxygen lance mechanical manipulator

This utility model is to be used for the preceding structural establishment of the various AC and DC electric arc furnace of steel industry fire door.It can once be sent into oxygen rifle, carbon rifle and combustion-supporting rifle in the electric furnace, carries out oxygen, the carbon dust of various necessity and carry and the operation of fluxing when molten steel is smelted.Make stokehold workman operation very simple and convenient, greatly reduce operator's labour intensity, realize the electrosmelting automatization.

Electric furnace is an Electric furnace steel making equipment with the furnace door carbon oxygen lance mechanical manipulator, it is made up of parallel four connecting rod principal arms, wander commentaries on classics bearing, the rotary head of wandering, rifle body, rifle body support frame and hydro-cylinder and water cooling tube etc., its transmission principle is to utilize parallel four connecting rod principles reposefully to send into electric furnace in from the original position spray gun, to carry out various smelting operations, after finishing, task sends it back to original place again, and the rifle body is overlapped with principal arm, make the stokehold area occupied reach minimum.German FUCHS company furnace door carbon oxygen lance mechanical manipulator is state-of-the-art technology and equipment in the prior art, and the oxygen rifle of this equipment and water cooled holder are an integral solder structure, and the swivel bearing sealed structure is adopted in the hinge point sealing.Its weak point is: (one) changes very difficulty when the oxygen rifle damages in smelting process, stop using if will only change, and gun barrel and water cooled holder are severed, and just can keep in repair, i.e. inconvenience maintenance is again produced in influence.(2) the water-cooled swivel joint is if will play good sealing function, and the working accuracy of its trim, setting accuracy and smooth finish all require very high, and are not suitable for working under the environment harsh conditions.Facts have proved that this robot device is in use changed extremely inconvenience of gun barrel, and in using less than year, its swivel joint position seriously leaks, what directly influence was produced normally carries out.

The utility model provides a kind of rifle body dismounting and easy to maintenance, and rotation is flexible, the electric furnace of water-cooled pipe joint good seal furnace door carbon oxygen lance mechanical manipulator.

The utility model is by the rifle body, the rifle body support frame, parallel four connecting rod principal arms, water cooling tube, compositions such as hydro-cylinder, characteristics are that the rifle body support frame adopts the rotary head supporting of wandering, principal arm adopts the commentaries on classics bearing support of wandering, described rifle body support frame is designed to a movable removable support, and promptly described rifle body support frame not only is connected to removable mechanical connection with the rotary head of wandering of principal arm termination, and the rifle body support frame is connected with the rifle body and also is removable mechanical connection; Principal arm is the water-cooled case structure, and diversion between principal arm and rifle body and return water pipe adopt hose construction, its interface flange seal.

The utility model compared with prior art, advantage is: rotating bearing is all adopted in (1) principal arm and the rotation of rifle body, promptly rotation is safe and reliable again flexibly, and can in stove, finish and advance, retreat, functions such as rising, descend and swing, can change according to the requirement of molten bath oxygen supply and the turning angle of stove, adjust oxygen-blowing gun position, angle and blowing track flexibly, give execute-in-place convenient with maximum.(2) suction between principal arm and the rifle body and return water pipe adopt hose construction, its interface is tightly connected with flange, has not only guaranteed the handiness of rifle body rotation but also thoroughly solved German FUCHS company to produce the unconquerable seal leakage problem of swivel bearing joint in the mechanical manipulator.(3) the rifle body support frame is designed to a movable removable support, has changed German FUCHS company and has produced in the mechanical manipulator shape that rifle body and rifle body support frame is designed to the integral solder structure, the maintenance of rifle body, changes easily.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the plan structure synoptic diagram of the utility model mechanical manipulator.

Fig. 2 is the structural representation of facing of the utility model mechanical manipulator.

Fig. 3 changes the N of bearing to synoptic diagram for principal arm among Fig. 2 with wandering.

1 is the rifle body among Fig. 1, Fig. 2, Fig. 3, and 2 is the water-cooled flexible pipe, and 3 is the rifle body support frame, and 4 are the rotary head of wandering, and 5 is principal arm, 6 are the commentaries on classics bearing of wandering, and 7 is hydraulic efficiency system, and 8 is water-cooled baffle, and 9 is rifle body briquetting, 10 is pull bar, and 11 is the pull bar rotary track, and 12 is the principal arm rotary track, and 13 is electric furnace.

During work, after rifle body (1) enters body of heater by hydraulic efficiency system (7) driving principal arm (5) automatically from original position (accompanying drawing dotted line position) rotation, drive by a pull bar (10) that has retractor device in four connecting rods, swing, being driven by hydraulic efficiency system simultaneously swings up and down rifle body (1), like this, can regulate operating angle arbitrarily during the rifle body running in stove, structure is very simple compact.When returning original position, its oxygen gun body can be automatically under the control of four connecting rods close up with big arm, and it is little that this equipment is taken up room in during inoperative.

Claims

1, a kind of electric furnace furnace door carbon oxygen lance mechanical manipulator, it is by the rifle body, the rifle body support frame, parallel four connecting rod principal arms, water cooling tube, compositions such as hydraulic efficiency system, it is characterized in that: the rifle body support frame adopts the rotary head supporting of wandering, principal arm adopts the commentaries on classics bearing support of wandering, described rifle body support frame is designed to a movable removable support, that is: described rifle body support frame not only is connected to removable mechanical connection with the rotary head of wandering of principal arm termination, and the rifle body support frame is connected with the rifle body also and is removable mechanical connection, principal arm is the water-cooled case structure, principal arm adopts hose construction to diversion between the rifle body and return water pipe, and its interface is tightly connected with flange.
