The utility model discloses utilizing wire rope and rope sheave to convert the displacement volume of clay gun piston the rotation angle of pointer into, not only having realized the accurate measurement of the blast -furnace mud gun volume of beating mud, have simple structure moreover, low cost maintains advantages such as convenient.
Description
Technical field
This utility model is related to a kind of device for showing clay gun of blast furnace amount, belongs to technical field of metallurgical equipment.
Background technology
At present, the mud amount of beating of most domestic blast furnace gun is shown by vertical machine sl iotadeways instruction device, this
The shortcoming of kind of instruction device is that indicating graduation is few, error is big, and the reality that operator is difficult to get hold of each heat clay gun beats mud amount,
Easily cause ferrum mouth depth unstable, tapping outlet difficulty increases, not only waste stemming, and increased the consumption of drill bit, drilling rod
Amount.Additionally, long-term control is bad beats mud amount, also can make ferrum mouth job insecurity, ferrum mouth local temperature raises, and serious also can
Induction hearth breakout accident.The advanced large blast furnace of minority employs digital mud quantity display apparatus, digital mud quantity display apparatus
Although display precision is high, it is expensive, maintenance cost high it is difficult to large-scale promotion application.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of clay gun of blast furnace amount display dress
Put, while ensureing display precision, reduce manufacture and the maintenance cost of display device.
Problem described in the utility model is to be realized with following technical proposals：
A kind of clay gun of blast furnace quantity display apparatus, composition includes pointer, graduated disc, back-moving spring, rope sheave and steel wire
Rope, described graduated disc is fixed on clay gun end cap by support, and described rope sheave and graduated disc coaxially and pass through bearing and graduated disc
Holder pivots connect, described pointer is located at the front portion of graduated disc solid with rope sheave by running through the mandrel of scale center hole
Connect, described steel wire rope is wound on rope sheave, and its one end is fixedly connected with rope sheave, the other end is fixing after the through hole through on clay gun end cap
On the piston of clay gun, described back-moving spring is arranged between rope sheave and the support of graduated disc.
Above-mentioned clay gun of blast furnace quantity display apparatus, also include fixed pulley in composition, and described fixed pulley is arranged on clay gun end
Cover, the steel wire rope being wound on rope sheave is connected with the piston of clay gun behind fixed pulley change direction.
The displacement of clay gun piston is converted to the anglec of rotation of pointer using steel wire rope and rope sheave by this utility model, not only
Achieve the accurate metering of clay gun of blast furnace amount, and there is structure simply, with low cost, the advantages of easy to maintenance.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the left view of Fig. 1；
Fig. 3 is A-A sectional view.
In figure is respectively numbered：1st, pointer；2nd, graduated disc；3rd, back-moving spring；4th, rope sheave；5th, fixed pulley；6th, clay gun end cap；7、
Piston；8th, steel wire rope.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1, Fig. 2 and Fig. 3, this utility model mainly includes pointer 1, graduated disc 2, back-moving spring 3, rope sheave 4, fixed cunning
Wheel 5 and steel wire rope 8.Graduated disc 2 is fixedly connected with the shell of clay gun by support, and rope sheave 4 is coaxially installed on the back side of graduated disc 2
And be connected with the holder pivots of graduated disc 2 by bearing, when rope sheave 4 rotates under the driving of steel wire rope 8 and back-moving spring 3,
It is arranged on before graduated disc 2（Carry graduated one side）And it is fixing with rope sheave 4 by running through the mandrel of scale center hole
The pointer 1 connecting can be with rope sheave 4 synchronous rotary.Around a circle on rope sheave 4, its one end is fixed on rope sheave 4 steel wire rope 8, another
End first bypasses fixed pulley 5, is fixed on clay gun piston 7 after being then passed through the through hole on clay gun end cap 6.5 regulation steel wires of fixed pulley
The effect of rope 8 trend, if the installation site of rope sheave 4 is properly it is also possible to cancel fixed pulley 5.Back-moving spring 3 is arranged on rope sheave 4
And the support of graduated disc 2 between, when clay gun piston 7 moves backward, back-moving spring 3 can drive rope sheave 4 by steel wire rope 8 and refer to
Pin 1 reversely rotates.
The operation principle of this clay gun of blast furnace quantity display apparatus is：Pull when clay gun piston 7 moves forward in mud cylinder
Steel wire rope 8, steel wire rope 8 changes direction rear-guard running rope wheel 4 through fixed pulley 5 and rotates, and rope sheave 4 is again by running through scale center hole
Mandrel drives pointer 1 synchronous rotary, when piston 7 stops mobile, can calculate blast furnace gun according to the angle that pointer 1 turns over
Beat mud amount.During clay gun piston 7 is moved rearwards by, steel wire rope 8 drives lower band running rope wheel 4 He in the elastic force of back-moving spring 3
Pointer 1 rotates backward, and clay gun piston 7 moves forward and backward and once completes once to beat mud instruction process.
