The present invention is another the chute inclination angle transmission rig that provides for " device with hydrostatic transmission for feeding material " (application number 85109284).This mechanism replaces parts such as the original backing ring of " device with hydrostatic transmission for feeding material " (application number 85109284), jib, conical bearing roller, horizontal gear wheel, further simplifies the internal structure of an organization with inside and outside not toothed decussation roller (or ball) bearing of a standard type and Internal and external cycle stiffening plate thereof, make things convenient for processing and manufacturing, installation and maintenance, alleviate weight of equipment, reduce investment outlay, prolong equipment life.
Description
The present invention relates to a kind of chute inclination angle transmission rig of blast furnace bell-less loading device.
The feeder apparatus that at present most in the world blast furnaces use still is the PW type sun and planet gear different gear reducer transmission rig of Luxembourg.Though several times improve, ultimate principle does not become.
The transmission rig at Luxembourg PW type blast furnace bellless distributor chute inclination angle is that the moving side of the auxiliary motor that will transmit through the sun and planet gear different gear reducer by a master wheel with double flank of tooth reaches worm and wormwheel, fan type gear, drive gudgeon, realize that chute fascinates.This drive system structure complexity, design, processing and manufacturing and repairing are safeguarded and are all compared difficulty, invest also big.For many years, many people want to change this type of drive, and other wards off new footpath.
On March 26th, 1985, a blast furnace BT-83 of China Baogang type device with hydrostatic transmission for feeding material is gone into operation.Production practice over one year facts have proved, operational excellence has obtained user's favorable comment.With regard to this technology, iron and steel design and research institute in packet header is called " device with hydrostatic transmission for feeding material " on December 19th, 1985 with name and has applied for patent.Application number 85/109284.14 people such as contriver monk Quan Song.
The chute inclination angle transmission rig of " device with hydrostatic transmission for feeding material " (application number 85109284) is to utilize three synchronous fuel tanks (mechanical synchronization or electro-hydraulic servo the are synchronous) piston rod on the airtight box top cover to affect the translation up and down of horizontal backing ring.On the horizontal backing ring raceway is arranged.Between backing ring and the gudgeon pivoted housing jib is arranged, several conical bearing rollers that transverse axis is arranged are equipped with in the jib outside, and the conical bearing roller puts in the backing ring raceway.Stable in order to ensure the jib center, on jib, be provided with several horizontal gear wheels that vertical shaft is arranged again.Horizontal gear wheel abuts against the vertical rail level on the backing ring.Jib is provided with horizontal guide groove.Crank is sleeved on the gudgeon with the spline form, and the tail end of crank has roller, and it puts in the horizontal guide groove on the jib.When the gudgeon pivoted housing rotated, jib is rotation and then.Tapered roller and horizontal gear wheel roll on its rail level.When three synchronous fuel tanks are leading horizontal backing ring up and down during translation, jib is and then up and down translation simultaneously, and the crank tail wheel that horizontal guide groove band wherein moves up and down and since crank one end and gudgeon fix can not about, crank and tail wheel have to rotate around gudgeon, and gudgeon drives chute and fascinates.Not only rotate but also fascinate, can be combined into any mode of motion of arts demand.
Kawasaki, Japan system iron has been developed the bf fabric device of the outer shaking table formula transmission of a kind of garden conical tube type chute stove.Begin at a 400M in July, 1985
3The small furnace of ferroalloy smelting on test.
The simple and easy no bell of No. 2 blast furnaces of China Kunming Iron and Steel Works is gone into operation early, and its chute fascinates and adopts directly the leave behind way of end of pull bar.
Can also enumerate in addition, but not try out more.The chute inclination angle transmission rig of " device with hydrostatic transmission for feeding material " (application number 85109284) and gudgeon rotation PW sun and planet gear be differential, and to subtract the device transmission system different fully.It is simple that both compare former structure, and handling ease is easy to maintenance, and is sturdy and durable.But, since gapped between backing ring and the casing slideway, also gapped between jib and the gudgeon pivoted housing, and backing ring, the two unsteady phenomenons of jib have appearred.
The objective of the invention is in order further to simplify and improve the chute inclination angle transmission rig of " device with hydrostatic transmission for feeding material " (application number 85109284).The present invention provides the chute tilting mechanism of a kind of vertical translation bearing transmission for it.
Chute tilting mechanism synoptic diagram and the local enlarged diagram of accompanying drawing 2 vertical translation bearing transmission chute tilting mechanisms with reference to accompanying drawing 1 vertical translation bearing transmission describe.
The present invention adopts a horizontal positioned.Identical with gudgeon pivoted housing underslung bearing model.Specification is big some.Not with in decussation roller (or ball) standard bearing (11) of external tooth.Replace backing ring in above-mentioned " device with hydrostatic transmission for feeding material " (application number 85109284) and jib and on annex.
Among the present invention.Vertical slipper (14) on the outer ring of bearing (11) and its stiffening plate (12) and the stiffening plate.Be equivalent to original backing ring, vertical slipper and raceway.The inner ring of bearing (11) and its stiffening plate (10), and the crank tail wheel guide groove (5) that stiffening plate adheres to below is equivalent to original jib and tail wheel guide groove, roller (or ball) then is equivalent to original cone pulley and horizontal gear wheel.Establish enough studs on the inside and outside stiffening plate, to guarantee the rigidity of inside and outside stiffening plate.Three hinges that link to each other with the synchronous fuel tank piston rod are set on the outer stiffening plate.When three piston rod synchronization telescopes, the vertical thereupon translation of whole bearing, the crank tail wheel guide groove of setting up under the interior stiffening plate drives crank and rotates around gudgeon, and promptly chute fascinates.Because bearing enclose " separation ", inner ring and stiffening plate thereof can rotate when chute fascinates.Reaching chute rotates not only but also fascinate.According to the requirement of smelting technology, can form various distributing modes.The rotation of inner ring solves by several different methods.1. drive with crank and tail wheel thereof, about horizontal group mode.2. two steamboats with transverse axis are set on the interior stiffening plate clamp the vertical stud (25) that is located on the gudgeon pivoted housing.When the gudgeon pivoted housing rotates, thus vertical stud stir steamboat on the inner ring rotate thereupon realized inner ring and on annex rotatablely move together.3. a trundle with radial level axle is set on the bearing inner race stiffening plate.The rotational symmetry line of the crank tail wheel guide groove on its axis and the inner ring stiffening plate coincides.Correspondingly two vertical studs are being set about two gudgeon symmetric line on the gudgeon pivoted housing.Just clamp the trundle on the inner ring.And little band gap, bearing translation up and down when making the rotation of gudgeon pivoted housing rotating band dynamic bearing inner ring, its power transmission point is the contact of rolling.The lubricated of this roller can adopt the drier oil case fuel feeding that carries, also can be by the raceway of bearing outer ring through sized cross roller bearings, bearing inner race continuous oil supply.
This structure has adopted a standard rolling bearing and structural part to make up backing ring, jib, roller, the horizontal gear wheel that has replaced in the former transmission system, in addition parts significantly reduce, amount of finish minimizing, weight saving, installation, easy to maintenance, reliable, the life-span is long, has reduced facility investment.
