Description
The utility model belongs to the blast furnace servicing installation, and particularly a kind of blast-furnace tuyere disassembly-and-assembly machine is used for removing and installing blast-furnace tuyere.
The air port is often burnt out in blast furnace ironmaking production, and changing the air port needs special-purpose mechanical means that bad air port is disassembled, and installs new air port.Employed air port disassemblerassembler adopts air port demountor and air port fitting machine respectively in the blast furnace ironmaking production at present.The major parts of air port demountor hits pneumatic hammer, pneumatic hammer by travelling car, front and back leveling hydraulic lifting oil cylinder, horizontal girder, backhander and moves master cylinder, tears the air port gib head open and hydraulic control system, pneumatic control system are formed (seeing accompanying drawing 5).The air port fitting machine mainly by travelling car, front and back leveling hydraulic lifting oil cylinder, install that cut somebody's hair, just hitting pneumatic hammer in the air port, pneumatic hammer moves master cylinder and hydraulic control system, pneumatic control system is formed (seeing accompanying drawing 6).
The dismounting in each air port and installation are proceed step by step.Horizontal girder before will tearing the air port machine open and shifting the air port onto, is risen by the front and back hoist cylinder in first dismounting air port, align the air port, again backhander is hit pneumatic hammer and dismounting air port gib head puts in the air port, open pneumatic control system, backhander hits pneumatic hammer and begins reverse strike, by hitting repeatedly, the air port is disassembled.To tear the air port dolly then open pulls out and hangs away, before will adorning the air port dolly again and winching to the air port, rise horizontal girder with front and back leveling hoist cylinder equally, cut somebody's hair fresh wind port under the effect of hitting power just by just hitting pneumatic hammer and dress air port, with the air port installation in position, finish more changing jobs of air port.
Hence one can see that, air port of every dismounting, hang two equipment that change by crane, needing to push away first two demolition, installation instrument and backhander with air port gib head, air port hits pneumatic hammer, just hits two pneumatic pneumatic hammers of pneumatic hammer and be used alternatingly and finish air port dismounting, installation work, need carry out multi-pass operations, the working routine more complicated.Need several operator to carry out multi-pass operations simultaneously and just can finish the air port disassemble and assemble work.
The purpose of this utility model provides and a kind of backhander pneumatic hammer and forehand pneumatic hammer is fitted together, and can will tear the air port gib head open, adorn the incorporate blast-furnace tuyere disassembly-and-assembly machine of cutting somebody's hair and fit together in the air port of dismounting, simplify blast-furnace tuyere dismounting operation, reach save time, laborsaving, improve operating efficiency, reduce the blast furnace staying time, improve the purpose of furnace processor.
The utility model is realized by following technical proposals.
Blast-furnace tuyere disassembly-and-assembly machine of the present utility model comprises travelling car, front and back leveling hydraulic lifting oil cylinder, horizontal girder, just hits that pneumatic hammer, backhander hit pneumatic hammer, tear the air port gib head open, cut somebody's hair in the dress air port, push-pull rod, hydraulic control system, the master cylinder of driving pneumatic hammer, pneumatic control system.Being characterized in just hitting pneumatic hammer and backhander hits pneumatic hammer assembling and is serially connected and forms the integral type pneumatic hammer, this integral type pneumatic hammer bottom is the dovetail type guide path, be slidingly matched with the guide rail of horizontal girder 3, a master cylinder is connected to this pneumatic hammer bottom, adorn a built-up type dismantling devices being contained in the front end that backhander hits the push-pull rod of pneumatic hammer front end, by tear the air port gib head open, cut somebody's hair and the air port claw hook is formed in the dress air port, cut somebody's hair and are removably mounted on the claw hook of air port in air port gib head and air port.
According to blast-furnace tuyere disassembly-and-assembly machine of the present utility model, distribution valve chamber, back distribution valve chamber are provided with valve block before being provided with around the tup that just hits pneumatic hammer in the described integral type pneumatic hammer in the distribution valve chamber.The tup that backhander hits pneumatic hammer also is provided with preceding distribution valve chamber and back distribution valve chamber on every side, is provided with valve block in the distribution valve chamber.The distribution amount difference of these valve blocks just makes, backhander hits pneumatic hammer that different ballistic works is arranged, and promptly makes surging force to be installed greater than the dismounting surging force.
According to blast-furnace tuyere disassembly-and-assembly machine of the present utility model, dolly can advance under the driving at hydraulic efficiency plant on the tuyere platform or retreat, and disassembly-and-assembly machine is parked on the needed working position.Adopt composite entity formula air port dismantling devices, can finish the dismounting and the installation in air port, saved the number of times of the instrument of changing, simplified operation with this composite entity formula dismantling devices.
According to blast-furnace tuyere disassembly-and-assembly machine of the present utility model, to just hit pneumatic hammer and backhander hits pneumatic hammer and is combined into one the formula pneumatic hammer, be installed on the dismounting car body, therefore can finish dismounting, the installation in air port as long as adjust a disassembly-and-assembly machine, backhander is hit try hard to keep hold constant, positive hitting power then increases many, is adapted to the processing requirement of dismounting fully.
Blast-furnace tuyere disassembly-and-assembly machine of the present utility model, compact construction, control is simple, and is flexible to operation.Shorten the replacing time of blast-furnace tuyere, thereby shortened the blast furnace staying time, improved the operating rate and the productivity of blast furnace.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a built-up type dismantling devices synoptic diagram of the present utility model.
Fig. 3 is that the A-A of Fig. 2 is to view.
