Description

A kind of improved blast furnace stokehold Hydraulic clay gun angling cylinder
Technical field
Iron-smelting furnace stokehold Hydraulic clay gun technical field is the utility model is related to, more specifically refers to a kind of improved ironmaking Hydraulic clay gun angling cylinder before State of Blast Furnace.
Background technology
Hydraulic clay gun is the casthouse equipment of blast furnace, and it can quickly and accurately block the tapping hole after putting iron, make height Stove rapidly enters the operation of next circulation.1#2# blast furnaces stokehold Hydraulic clay gun includes single-revolution oil cylinder, reference picture 5 and figure 6, the end of piston rod 2 ' of the angling cylinder passes through oil pipe crossbeam 3 ', sets a transition valve block respectively in the both sides of piston rod 2 ' 4 ', the transition valve block 4 ' is above respectively equipped with an oil connection 5 ', and the hydraulic fluid port of oil connection 5 ' is radially arranged along piston rod 2 '.
Periodically Hydraulic clay gun angling cylinder is overhauled to ensure that blast furnace normally produces needs.With continued reference to Fig. 5 and figure 6, angling cylinder needs to pull down angling cylinder when overhauling, because the maximum outside diameter of both sides transition valve block 4 ' exceedes oil cylinder crossbeam hole 31 ' diameter, when angling cylinder dismounts, piston rod 2 ' may pass through oil cylinder crossbeam hole 31 ', but the transition valve of both sides by flexible Block 4 ' can not but pass through oil cylinder crossbeam hole 31 '.Therefore under normal circumstances, dismounting angling cylinder will first remove transition valve block 4 ', Specific purpose tool is made again oil cylinder crossbeam hole 31 ' is crossed into the end of piston rod 2 ' using jack top, could complete the disengaging of piston rod 2 ' Work.When angling cylinder is installed, draw ring need to be welded in the end of piston rod 2 ', then oil cylinder crossbeam 3 ' is pulled through by chain block, just may be used Complete oil cylinder and pass through work.It so will result in angling cylinder replacing efficiency lowly and maintenance personal's labor intensity be big.More Required maintainer up to 8 during changing, about 7 hours of repair time, the production of blast furnace are constrained significantly.Therefore, we A kind of improved blast furnace stokehold Hydraulic clay gun angling cylinder is provided.
The content of the invention
The utility model provides a kind of improved blast furnace stokehold Hydraulic clay gun angling cylinder, is torn open with solving angling cylinder Because transition valve block can not pass through oil cylinder crossbeam hole when unloading, causing angling cylinder to be changed, efficiency is low, labor intensity is big, replacing construction length With required maintainer it is more the problems such as.
The utility model adopts the following technical scheme that:
A kind of improved blast furnace stokehold Hydraulic clay gun angling cylinder, including cylinder barrel, piston rod, oil cylinder crossbeam, transition Valve block and oil connection, the piston rod front end are penetrated in cylinder barrel, and the piston rod and the cylinder barrel are coaxial, the piston-rod end Through oil cylinder crossbeam, the transition valve block is fixed on piston-rod end end face by transition valve block fastening bolt, the transition valve The maximum outside diameter of block is no more than the outer peripheral edge of piston-rod end end face, and the transition valve block is provided with two oil connections, described The hydraulic fluid port of oil connection is axially arranged along piston rod.
Further, the Hydraulic clay gun angling cylinder also includes a round nut, and the round nut is provided with internal thread, The piston rod is being provided with the longitudinal external screw thread being adapted with the round nut internal thread, institute with oil cylinder crossbeam junction front end Round nut is stated to be screwed onto at the external screw thread of the piston rod longitudinal direction.
Further, the transition valve block is cylinder, the external diameter of the transition valve block and the piston-rod end end face External diameter is equal.
Further, the oil connection on the transition valve block end face is symmetrical arranged on piston rod axis.
From the above-mentioned description to the utility model structure, compared to the prior art, the utility model has following excellent Point:
1st, piston-rod end is arrived due to transition valve block being changed, and transition valve block maximum gauge is no more than outside piston-rod end Footpath, it can directly be passed through using hydraulic system self-acting completion piston rod, depart from oil cylinder crossbeam, therefore blast-furnace hydraulic mud gun returns The replacing construction for turning oil cylinder shortens to 4 hours by 7 original hours, reduces influence of the maintenance process to production, for height The production of stove provides favourable conditions.
2nd, the utility model simplifies the maintenance step of Hydraulic clay gun angling cylinder, and the work for reducing maintainer is strong Degree, maintainer are also reduced to 5 people by 8 original people.

Embodiment
Illustrate specific embodiment of the present utility model with reference to the accompanying drawings.
Hydraulic clay gun angling cylinder before a kind of improved State of Blast Furnace, referring to Figures 1 and 2, including cylinder barrel 1, piston rod 2, oil Cylinder crossbeam 3, transition valve block 4 and oil connection 5, the front end of piston rod 2 is penetrated in cylinder barrel 1 to be connected with piston, the end of piston rod 2 then position In outside cylinder barrel 1, the piston rod 2 and cylinder barrel 1 are coaxial.One transition is fixed by transition valve block fastening bolt 41 in the end of piston rod 2 Valve block 4, it is preferable that the transition valve block 4 is cylinder, and its maximum outside diameter is no more than the outer peripheral edge of the distal end faces of piston rod 2, in mistake Cross on valve block 4 and be additionally provided with two oil connections 5.
Reference picture 1, an oil cylinder crossbeam hole 31 is opened up among oil cylinder crossbeam 3, the diameter in the oil cylinder crossbeam hole 31, which is more than, lives The diameter of stopper rod 2, the end of piston rod 2 is passed through into the oil cylinder crossbeam hole 31.When removing angling cylinder, due to the end of piston rod 2 Diameter be less than oil cylinder crossbeam hole 31 diameter, therefore piston rod 2 can by hydraulic system self-acting complete expanding-contracting action, So as to realize that work is passed through in the disengaging of piston rod 2 from oil cylinder crossbeam 3.
Reference picture 1, Fig. 3 and Fig. 4, angling cylinder also include a round nut 6, and the round nut 6 is provided with internal thread, living The longitudinal external screw thread 21 being adapted therewith is provided with the junction front end of oil cylinder crossbeam 3 on stopper rod 2, the round nut 6 is screwed onto work At stopper rod longitudinal screw 21.Two oil connections 5 of the end of piston rod 2 are respectively to be closed into and out of hydraulic fluid port, the two oil connections 5 Set in the axisymmetrical of piston rod 2, the hydraulic fluid port of oil connection 5 is axially arranged along piston rod 2.
Specific embodiment of the present utility model is above are only, but design concept of the present utility model is not limited thereto, All changes for carrying out unsubstantiality to the utility model using this design, all should belong to the row for invading scope of protection of the utility model For.
