Description

Lid-moving machine

The utility model relates to a kind of lid-moving machine, is a kind of equipment that the large blast furnace casting house is handled first section operculum colpi of main iron hook that is used for.

The effect of lid-moving machine is to handle first section operculum colpi of tap drain to finish lifting, traversing and revolution action, for taphole drilling machine and clay gun work provide condition.In the prior art,, mainly form by walking car, traversing mechanism, hoisting appliance as disclosed lid-moving machine in " the modern large blast furnace equipment and the manufacturing technology " of 1996 publication of metallurgical industry press.The walking car is realized through chain drive by pneumatic (hydraulic pressure) motor by walking on the bogie wheel, side wheel and the track of top wheel below being set up in the blast-furnace tuyere platform that are mounted thereon.The turret mount of traversing mechanism is installed on the walking vehicle carriage by bearings, and its cylinder body that drives gas (hydraulic pressure) cylinder is hinged on the vehicle frame of walking car, and piston rod head and turret mount are hinged.Hoisting appliance is the leverage by the air cylinder driven lifting, and lever head is a lifting dog, and the fulcrum of lever and lifting drive gas (hydraulic pressure) cylinder and all be hinged on the turret mount of traversing mechanism.In addition, also promising equipment provides the compressed air pipe (hydraulic oil pipe) and the lubrication management of power, and compressed air pipe (hydraulic oil pipe) and lubrication management are all realized and being connected of the car of walking by flexible pipe and towline supporter.During work, gas (hydraulic pressure) cylinder activation lever head lifting dog is mentioned operculum colpi, and the walking car retreats, and gets out of the way clay gun or taphole drilling machine working position.To taphole drilling machine or clay gun end-of-job, lid-moving machine resets operculum colpi.Operculum colpi just hangs over lever head generally speaking, when needs are changed operculum colpi, and the traversing mechanism rotation, hoisting appliance puts down old operculum colpi, mentions new operculum colpi, makes new operculum colpi in place.Its existing weak point is: track is positioned at about 2-3 rice directly over the main iron hook, and thermal distortion takes place easily in the baking of bearing high temperature liquid iron, the normal operation of influence walking car; The car of walking simultaneously is operated under the severe environment of the many dust of high temperature above the tap drain, increased manufacturing, maintenance requirement to equipment, and equipment is positioned at all below the tuyere platform, inconvenient maintenance.The load of lid-moving machine and operculum colpi all herein on the tuyere platform, has strengthened tuyere platform design, manufacture difficulty by rail effect.For the flexible pipe of equipment fuel feeding, air feed and towline supporter are in the severe environment of the many dust of high temperature of tap drain top, high temperature has quickened the aging of sebific duct, in case but and leakage of oil fire hazard.In addition, for the smaller blast furnace of adjacent two iron mouth angles, because clay gun has occupied both sides, the centre is the moving area of operculum colpi, so tuyere platform is difficult to establish pillar in this zone, span is very big.Therefore, be that locus or tuyere platform stressing conditions do not allow to install simultaneously in this position two lid-moving machines.

The purpose of this utility model provide a kind of simple in structure, equipment dependability is high, operating maintenance is convenient, the civil engineering workload is few, and is specially adapted to the lid-moving machine that uses on the very little blast furnace of adjacent two iron mouth angles.

The purpose of this utility model is achieved through the following technical measures.

A kind of lid-moving machine, have turn around table, track, walking car, hoisting appliance, turn around table is installed by bearing and is supported on fixedly on the support, track laying is on turn around table, the walking car cooperates with track by its wheel and is installed on the track, on the walking car car body hoisting appliance of being made up of lever and lifting hydraulic cylinder is installed, the front end of lever is a lifting dog.

The lever end of hoisting appliance is articulated on the walking car car body, and lifting hydraulic cylinder one end is articulated on the walking car car body, the hinged middle part that is supported on lever of the other end.

Bearing is the rotating bearing with external toothing, and the pinion(gear) that is installed on the oil motor is meshed with the external toothing of rotating bearing.

Track is a flange rail, and the wheel of walking car is fitted in the groove of track.

The walking car is driven through chain-drive mechanism by oil motor, and two sprocket wheels of chain-drive mechanism are fixed in the two ends of track, and the two ends of its chain are connected with the car body of walking car.

The advantage that the utility model is compared with prior art had is: 1. equipment is installed on the other casting house service platform of tap drain, and leave the certain distance of tap drain, not toasted by molten iron, reduced manufacturing, the maintenance requirement of equipment, simple in structure, improved working reliability; 2. support can be directly fixed on the foundation of civil work of casting house platform, and the civil engineering workload is few; 3. equipment is positioned on the service platform, and overhauls and can directly use the factory building crane, and good operation conditions is convenient to maintenance; 4. this equipment can be installed between two tap drains for the very little blast furnace of adjacent two iron mouth angles, the shared lid-moving machine of two tap drains both can satisfy the need of work of two tap drains, can save facility investment again, therefore was particularly suitable for using in this occasion.In addition, when lid-moving machine carries operculum colpi and moves on to off-position, sizable iron mouth, tap drain, operculum colpi service clearance can be abdicated, and personnel's in particular cases the passage of withdrawing can be abdicated.

Below in conjunction with accompanying drawing embodiment of the present utility model is discussed in detail.

Fig. 1 is the structural representation of the utility model lid-moving machine.

Fig. 2 is the A-A sectional view of Fig. 1.

As shown in Figure 1 and Figure 2, the utility model lid-moving machine is mainly by fixedly support 1, rotating bearing 2, turn around table 3, track 4, walking car 5, hoisting appliance 6, chain-drive mechanism 8, pinion(gear) 9 and

oil motor

7,10 are formed.The rotating bearing 2 of turn around table 3 by having external toothing installed and is supported on fixedly on the support 1, and the pinion(gear) 9 that is installed on the oil motor 10 is meshed with the external toothing of rotating bearing 2, and transmission simply, reliably.Track 4 is laid thereon for the center of turning circle that flange rail is symmetrical in turn around table 2, and walking car 5 is fitted in by its wheel in the groove of track 4 to cooperate with track 4 and is installed on the track 4.Walking car 5 is driven through chain-drive mechanism 8 by oil motor 7, two sprocket wheels of chain-drive mechanism 8 are fixed in the two ends of track 4, the two ends of its chain are fixedly linked with the car body of walking car 5, avoid being equipped with a large amount of flexible pipes, chain supporting frame, further the working reliability of simplified apparatus, raising equipment.On walking car 5 car bodies hoisting appliance of being made up of lever 6a and lifting hydraulic cylinder 6b 6 is installed, the front end of lever 6a is a lifting dog, end is articulated on the car body of walking car 5, and lifting hydraulic cylinder 6b one end is articulated on walking car 5 car bodies, the hinged middle part that is supported on lever 6a of the other end.

Lid-moving machine is installed between two tap drains of the smaller blast furnace of adjacent two iron mouth angles, and center of turning circle is positioned on the symmetry axis of two tap drains, and support 1 is fixed on the concrete foundation of casting house platform.During work, walking car 5 is along track 4 walkings, and turn around table 3 can drive track 4, walking car 5, hoisting appliance 6 and operculum colpi and realize the revolution action.

The hydro-cylinder that is adopted in each transmission rig of the utility model lid-moving machine, oil motor all can be substituted by pneumatic linear actuator, pneumatic motor or electronic cylinder, electro-motor.
