Description

The spray gun transmission apparatus

The utility model relates to a kind of spray gun transmission apparatus, belongs to the equipment that is used to control the spray gun position in the blast furnace discharge yard winding-up desiliconization agent desiliconization system.

In the prior art, many manufacturers as Kawasaki, Japan company, Chinese Baoshan Iron ﹠ Steel Group Corp., adopt the jet desiliconization system in swinging flow jet molten iron surface of desiliconization agent.Its spray gun transmission apparatus mainly is made up of travelling platform, column, coaster, chain-drive mechanism, tilting mechanism.Travelling platform, is driven by chain-drive mechanism on the track that is laid on the swinging flow jet cover plate by wheel support.The column that both sides have parallel symmetrically arranged slideway is hinged on the bearing support that is fixed on the travelling platform by rotating shaft, tilting mechanism is made of electronic leading screw screw block and crank, the housing of electronic leading screw screw block is hinged on the travelling platform, the screw mandrel rod end of crank one end and leading screw screw block is hinged, and the other end is fixedly mounted in the rotating shaft of column.The roller of coaster is fitted in the slideway of column, and two sprocket wheels of chain-drive mechanism are installed on slideway two ends up and down, are fixed on supratrochlear spray gun by the drive of chain drive coaster and move up and down along slideway.This equipment can realize spray gun traversing, fascinate, three actions of lifting, satisfy the processing requirement of molten iron surface winding-up desiliconization agent in swinging flow jet.But because of all devices is installed on the travelling platform, have only vertical force and a spot of side force between wheel rim and the track, stability when guaranteeing that equipment is traversing, travelling platform need have enough big planar dimension, structure is huge, lifting inconvenience, and because the needs of maintenance swinging flow jet will hang the job site once with whole spray gun transmission apparatus at set intervals.Removal cable is arranged is lifting to this equipment claimed, fascinate and traversing power devices in addition, is in that cable works under hard conditions under the hot environment, and working reliability is affected.

The purpose of this utility model provides a kind of compact construction, is convenient to handling and installation, the spray gun transmission apparatus that working reliability is high.

The purpose of this utility model realizes by following measure.

A kind of spray gun transmission apparatus, have column, coaster and chain-drive mechanism, the column both sides have parallel symmetrically arranged slideway, the roller of coaster is fitted in the slideway of column, the motor that drive sprocket is installed of chain-drive mechanism is fixed on the column, two sprocket wheels are installed on slideway two ends up and down, and the two ends of chain are connected with coaster, and spray gun is fixed on the coaster.It also has support and beam, beam is hinged on the support by the vertical bearing pin, electronic its housing of leading screw screw block and screw mandrel rod end perpendicular to the setting of vertical bearing pin are hinged on respectively on support and the beam, column is hinged on the beam by horizontal bearing pin, is hinged on respectively on column and the beam perpendicular to electronic its housing of leading screw screw block and the screw mandrel rod end of horizontal bearing pin setting.

Be provided with the intermediate chain wheels that are installed on the column in the chain-drive mechanism, to increase chaindriven working reliability.

Electronic leading screw screw block also can be by Electrohydraulic push rod, or hydro-cylinder substitutes.

The advantage that the utility model is compared with prior art had is: replace the translational motion of travelling platform with the rotation of beam, compact construction has reduced the physical dimension and the weight of equipment, is convenient to handling and installation.Avoided under hot environment, using removal cable, improved working reliability.

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

Fig. 1 is the structural representation of the utility model spray gun transmission apparatus.

Fig. 2 is the vertical view of Fig. 1.

The utility model type spray gun transmission apparatus as shown in Figure 1 and Figure 2, mainly is made up of support 1, beam 5, column 7, coaster 10, electronic leading

screw screw block

3,4 and chain-drive mechanism.Beam 5 is hinged on the support 1 by vertical bearing pin 2, and electronic leading screw screw block 3 its housings and the screw mandrel rod end that are provided with perpendicular to vertical bearing pin 2 are hinged on respectively on support 1 and the beam 5.Column 7 is hinged on the beam 5 by horizontal bearing pin 6, and electronic leading screw screw block 4 its housings and the screw mandrel rod end that are provided with perpendicular to horizontal bearing pin 6 are hinged on respectively on column 7 and the beam 5.Column 7 both sides have parallel symmetrically arranged slideway, and the roller of coaster 10 is fitted in the slideway of column 7.Chain-drive mechanism is made up of motor 11, drive sprocket 12, intermediate chain wheels 13,

sprocket wheel

8,15 and chain 14, the motor 11 of drive sprocket 12 and intermediate chain wheels 13 are installed to be made one and is fixed on the column 7, two

sprocket wheels

8,15 are installed on slideway, and about in the of 7 two ends, and the two ends of chain 14 are connected with coaster 10.Spray gun 9 is fixed on the coaster 10.

Entire equipment 4 below support 1 have the preset pieces 1a of groove and cooperate with preset pieces 16 on being fixed in the swinging flow jet cover plate, place on the swinging flow jet cover plate.During work, 3 actions of leading screw screw block drive beam 5 and rotate around vertical bearing pin 2, move along the enough big circular arc of radius through column 7 and coaster 10 drive spray guns 9, finish the traversing action of similar prior art.4 actions of leading screw screw block drive column 5 and rotate around horizontal bearing pin 6, drive spray gun 9 through coaster 10 and fascinate.Motor 11 starts, and drives the slideway traveling of coasters 10 along column 7 by motion-work wheel 12, intermediate chain wheels 13, last

lower sprocket

8,15 and the transmission chain 14 that is installed on its output shaft, realizes the lifting action of spray gun 9.When changing lance head, strengthen stretching out or the indentation amount of leading screw screw block 3, can make spray gun 9 forward enough distant places to apart from the working position, carry out the replacing operation of spray gun 9 easily.
