Abstract
The utility model belongs to grinding equipment for maintaining a matched surface of a relief valve and an equalizing valve of an iron-making blast furnace and particularly relates to an automatic grinding machine for the relief valve and the equalizing valve. A portal bracket with a balance bar is fixedly connected onto a base; a nut fixedly connected with the center of the balance bar is matched with an adjusting screw rod; a pressure plate is fixedly connected to the lower end of the adjusting screw rod; a base plate is fixedly connected to the top of a support pillar arranged on the base in the portal bracket; a speed reducer driven by an electric motor is mounted on the base; a vertical shaft connected with an output shaft of the speed reducer extends out of a central hole of the base plate; a grinding turntable is fixedly connected to the upper end of the vertical shaft; bolt holes are uniformly formed in the grinding turntable; and the axis of the adjusting screw rod is superposed with that of the vertical shaft. The automatic grinding machine disclosed by the utility model has the advantages of reasonable structure, reliable performance, high grinding and processing efficiency and favorable processing quality; the grinding quality can be guaranteed to meet the technical standard; the labor intensity is reduced; the work time is shortened; and the maintenance cost is reduced.
Description
Technical field
The utility model belongs to the milling apparatus that the maintenance blast furnace diffuses valve, equalizing valve mating surface, particularly a kind of valve, equalizing valve autogenous mill of diffusing.
Background technology
Equalizing valve, to diffuse valve be one of very important water-tight equipment of blast furnace furnace roof, because equalizing valve, the quality of diffusing valve directly have influence on the normal reinforced of blast furnace, so that it plays a part in production technology is very important.
Diffuse the water-tight equipment that valve and equalizing valve all belong to furnace roof, very high to the requirement of pressure-equalizing and discharging valve mating surface, require the gap of pressure-equalizing and discharging valve matching surface will reach≤0.02mm according to technical standard.This has just had higher requirement to off-line maintainer's repair quality, former off-line maintenance lapping diameter 550 diffuse valve the time, arrange 4 human manual methods to grind minimum 2 days, labour intensity is very big, does not reach desirable result of use toward contact.Because the instability of in the underhand polish process, exerting oneself, thus be easy to cause the deflection of pressure-equalizing and discharging valve matching surface, thus have influence on the Grinding Quality of pressure-equalizing and discharging valve.
Summary of the invention
The purpose of the utility model is to provide a kind of valve, equalizing valve autogenous mill of diffusing, and it is rational in infrastructure, dependable performance; Lapping efficiency is high, and crudy is good, can guarantee that Grinding Quality reaches technical standard; Reduce labor intensity, practice thrift man-hour, reduce maintenance cost.
The purpose of the utility model is achieved in that a kind of valve, equalizing valve autogenous mill of diffusing; Affixed portal trestle on base with balance bar, the nut affixed at the center of balance bar matches with regulating leading screw, affixed the platen in the lower end of regulating leading screw; Its top of the support column that is provided with on the base in portal trestle affixed the chassis; The reductor of electric-motor drive is installed on base, and the vertical pivot that speed reducer output shaft connects stretches out from the centre bore on chassis, affixed the grinding rotating disk in the upper end of vertical pivot; On the grinding rotating disk, be uniformly distributed with bolt hole is being set, regulate the axis and the vertical pivot dead in line of leading screw.
The course of work of the utility model: as grind a diameter 550 and diffuse valve; Only need to arrange 2 people to get final product; To diffuse valve through set bolt and install on the grinding rotating disk, mating surface is coated abrasive pastes, adjust in mating surface and the gap of using the adjusting leading screw will regulate valve gap affixed on the leading screw platen and valve seat then; Start power supply and begin to grind, only need suitably adjust in the process of lapping and regulate leading screw and get final product.Per 15 minutes stop wiping old abrasive pastes, coat new abrasive pastes then, and the gap of its mating surface of grinding of about about 6-8 hour of process just can reach in the 0.02mm like this, can reach the instructions for use of on-the-spot technology fully.The utility model is rational in infrastructure, dependable performance, and lapping efficiency is high, and crudy is good, has guaranteed that Grinding Quality reaches technical standard, has alleviated labour intensity, has practiced thrift man-hour, has reduced maintenance cost.
Description of drawings
To combine accompanying drawing that the utility model is done further to describe below, accompanying drawing 1 is the main TV structure sketch map of the utility model.
The specific embodiment
A kind of valve, equalizing valve autogenous mill of diffusing, as shown in Figure 1, affixed portal trestle on base 1 with balance bar 6; The nut affixed at the center of balance bar 6 matches with adjusting leading screw 5; Affixed the platen 4 in the lower end of regulating leading screw 5, its top of support column that is provided with on the base 1 in portal trestle affixed chassis 3, the reductor 10 of electric-motor drive is installed on base 1; 3 centre bore stretches out the vertical pivot 2 of reductor 10 output shaft couplings from the chassis; Affixed the grinding rotating disk 9 in the upper end of vertical pivot 2 is being provided with bolt hole grinding to be uniformly distributed with on the rotating disk 9, regulates the axis and vertical pivot 2 deads in line of leading screw 5.Reductor 10 is a cycloidal planetary gear speed reducer.Diffuse valve seat 8 grinding on the rotating disk 9 to be installed with through set bolt, regulate the platen 4 of leading screw 5 lower ends affixed diffuse valve gap 7, regulate and diffuse valve gap 7 and the fit clearance of diffusing the mating surface of valve seat 8 through regulating leading screw 5.
Claims (2)
