Abstract
The utility model discloses a lifting device for a high-speed wire collecting-coiling inner core rod and particularly relates to a method for collecting a high-speed wire coil, especially a method adopting the lifting of the collecting-coiling inner core rod. In order to solve the technical problems that an electric cylinder breaks down frequently and the consumption of spare parts is larger, the utility model provides the lifting device for the high-speed wire collecting-coiling inner core rod. The lifting device mainly comprises a three-position four-way reversing valve, a one-way throttle valve, a hydraulic cylinder, a proximity switch and the like. The inner core rod is driven by the hydraulic cylinder instead of the electric cylinder and the hydraulic cylinder is controlled by the three-position four-way reversing valve to reverse in direction so as to lift up and down. Compared with the prior art, the lifting device has the following advantages: the inner core rod is driven by the hydraulic cylinder and the hydraulic cylinder is small in volume, light in weight, convenient to install and easy to replace. The lifting device can greatly reduce the equipment failure rate of the inner core rod in a collecting-coiling area, save equipment cost and decrease the consumption of spare parts.
Description
Technical field
The utility model belongs to the Iron and Steel Production apparatus field, is specifically related to a kind of mode and lowering or hoisting gear thereof that plug goes up and down in the volume that collect, plug lowering or hoisting gear in particularly a kind of high line collection volume.
Background technology
Iron and steel is the alloy that iron and carbon, silicon, manganese, phosphorus, sulphur and a spot of other elements are formed.Wherein, outside the deironing, the content of carbon plays a key effect to the performance of iron and steel, so be called iron-carbon alloy again.The main production process of modern steel integrated complex is divided into two types: long flow process and short flow process.Long flow process is used the widest at present; Its process characteristic is: the iron ore raw material adopts blast furnace to produce molten iron, after Molten Iron Pretreatment after oversintering, pelletizing are handled; By pneumatic steelmaking, external refining to qualified composition molten steel; Be cast into difform strand by continuous casting, be rolled into all kinds of finished products, the iron and steel enterprise in the whole world about 70% takes this flow process to produce; Short flow process can be divided into two types again according to raw material; One type is iron ore behind direct melting and reducing, adopts electric furnace or pneumatic steelmaking, and its main feature is; The iron ore raw material is handled without sintering, pelletizing; Do not have the blast furnace ironmaking production link, this flow process is used less at present, accounts for below 10% greatly; Another kind of be with steel scrap as raw material, after melt smelting by electric furnace, get into subsequent process; There is not the blast furnace ironmaking production link yet; This technological process accounts for 20%, and in order to enhance productivity, domestic and international many steel plant also take to convert the technology of hot metal charging in electric furnace smelting at present.
In general, the production procedure of iron and steel comprises flow processs such as sintering, ironmaking, steel-making, continuous casting, steel rolling.Sintering is exactly iron mineral powder agglomeration, and for blast furnace provides a kind of method of fine fodder, it is to utilize Iron Ore Powder, flux, fuel and return mine and process a process of block raw materials for metallurgy by a certain percentage.The process of ironmaking is exactly the liquid pig iron that temperature and composition meet the requirements that obtains with the iron ore economical and efficient; Realize this process through blast furnace process; May be summarized to be: under the condition of low-energy-consumption of trying one's best; Through the reverse movement of controlled furnace charge and coal gas stream, processes such as high efficiency completion reduction, slag making, heat transfer and the reaction of slag iron obtain the comparatively desirable liquid metal product of chemical composition and temperature.Blast furnace burden is produced qualified molten iron through various chemical reduction reaction and is sent into steel-making through the torpedo jar then, goes into converter smelting Cheng Gang as steelmaking feed then.Slag enters slag bath through flush slag, separates through pulp water, and slag is drained, water circulation use.The byproduct that produces in the blast furnace ironmaking process---blast furnace gas is as uses such as low calorific value gas fuel heat supply wind furnace, sintering, boiler, preheating furnace and heating furnaces.Steel-making is meant that impurity such as carbon too much in the raw material (molten iron and steel scrap etc.), sulphur, phosphorus remove and add the process of the alloying component that adapts to.Continuous casting is meant molten steel in pans inject with water-cooled crystallizer continuously, behind the base shell that congeals into, pulls out with stable speed from crystallizer, through the water spray cooling, after treating all to solidify, is cut into the continuous casting billet of designated length again.Steel rolling is meant that the steel ingot that continuous casting comes out rolls into all kinds of steel with the hot rolling mode at different rolling mills with continuous casting billet, forms the process of product.
At present, the plug lowering or hoisting gear is that plug rises and down maneuver in being driven by electronic cylinder in the domestic more high line factory collection volume district.Jam takes place in rolling lead screw easily in the electronic cylinder, and the motor band-type brake needs often adjustment, rushes to summit easily.Electronic cylinder body is long-pending comparatively huge and heavy, and the space of installing is narrow, changes time and manpower that electronic cylinder needs labor.Because electronic cylinder failure ratio is more frequent, spare parts consumption is bigger, and is bigger to the production direct motion influence of high line.
The utility model content
The utility model is not enough to existing in prior technology; And plug lowering or hoisting gear in a kind of high line collection volume that provides; Plug lowering or hoisting gear in a kind of high line collection volume; Mainly comprise O type three position four-way directional control valve, one-way throttle valve, hydraulic oil pipe, hydraulic cylinder, connecting plate, interior plug, near switch and one group of bidirectional hydraulic lock, hydraulic cylinder and connecting plate are fixedly connected; Hydraulic oil pipe and hydraulic cylinder are suitable; Through the switching-over of O type three position four-way directional control valve control hydraulic cylinder, plug rose or descends in hydraulic cylinder drove through connecting plate again; The speed of hydraulic cylinder action is adjusted through two one-way throttle valves; Through three low level, meta and high-order three stations that guarantee interior plug near switch; One group of bidirectional hydraulic lock can stop hydraulic cylinder in any position.
In order to realize that hydraulic cylinder can stop in any position, meanwhile, prevent to let out in the hydraulic system, install one group of bidirectional hydraulic lock additional, play the pressurize effect.
In a word, the advantage of the utility model is: interior plug is driven by electronic cylinder and changes Driven by Hydraulic Cylinder into, through the switching-over of an O type three position four-way directional control valve control hydraulic cylinder; Control the speed that hydraulic cylinder rises or descends through the mode of two one-way throttle valve 2 meter outs; Realize that through one group of bidirectional hydraulic lock 3 hydraulic cylinder can stop and preventing letting out in the hydraulic system in any position.
The utility model compared with prior art owing to adopt Driven by Hydraulic Cylinder at the interior plug described in this utility model, the hydraulic cylinder volume is little and more in light weight, and is easy for installation, changes easily.Package unit is mainly formed by three position four-way directional control valve, one-way throttle valve, hydraulic oil pipe, hydraulic cylinder with near switch etc., and equipment cost is less, and spare parts consumption is less.Interior plug operation is more steady, and the speed of service is accelerated, and equipment failure rate reduces greatly.
