Abstract
An angular measurement device for a blast furnace tuyere consists of an angle board, an indicator, a conduit, a sliding sleeve, a small plate, a pull rod and a striking plate, wherein the small plate and the angle board are respectively fixed at the left end and the right end of the conduit, the indicator is arranged on the angle board and is in vertical state at all times by means of self gravity; two ends of the pull rod penetrating through the conduit extend outside the conduit, and the striking plate and a pull ring are fixedly arranged at the left end and the right end of the pull rod respectively; and the sliding sleeve is sheathed between the small plate outside the conduit and the angle board in a sliding way, and a big plate corresponding to the small plate is fixed on the sliding sleeve. The practical installation angle of a blast furnace tuyere sleeve can be conveniently and fast measured, and the difference between the practical installation angle and the designed installation angle can be timely calculated, thus a certain guiding role is played for operation of a blast furnace.
Description
Technical field
The utility model relates to a kind of device of measuring the tuyere cover of blast furnace setting angle, specifically a kind of blast-furnace tuyere angle measurement unit.
Background technology
Its circumferential direction of the blast furnace that is used to smelt iron has the air port of a plurality of air blast in stove, and each air port can be formed by water flowing refrigerative air port cover by one group, and air port cover segmentation is nested with together by large, medium and small three successively.Because the air port cover is contact furnace high-temperature (more than 1000 degree) directly, therefore, is damaged than being easier to, cover is damaged whenever the air port, and blast furnace just must be changed by damping down.Because the air port is that certain regulation is arranged when being enclosed within the design and installation angle; And must be up to specification; But owing to receive the influence of interior furnace charge of stove and operating environment; The requirement that air port cover actual angle after often when more fresh wind port overlaps, upgrading does not reach air port Analysis of Nested Design setting angle, control has constituted influence to blast furnace operating to a certain extent, is ten minutes necessity so measure its setting angle.
The device of announcing in " a kind of device and method of measuring blast furnace tuyere small sleeve or middle cover deformation angle " announced in the Chinese patent 200910217157.9; Form by thief rod, fine rule, graduated scale and weight; Come down to insert in the little cover through the plug awl of thief rod one end; Observe the terminal weight of thief rod and the situation that departs from of graduated scale then and measure, after manual calculation, finally draw the distortion situation.Though this kind device can use to a certain extent, has the problem of using difficulty, especially the plug of thief rod end awl is difficult to insert smoothly the air port cover and withdraws from the air port cover smoothly, causes use very inconvenient.
The utility model content
The purpose of the utility model is the deficiency to prior art, and a kind of blast-furnace tuyere angle measurement unit is provided, and is intended in time detect the tuyere cover of blast furnace setting angle, so that promote the raising of air port installation quality.The utility model solves the technical scheme that its technical problem takes: a kind of blast-furnace tuyere angle measurement unit is characterized in that it is by angle board, pointer, conduit, slip cap, deep bid, shallow bid, pull bar and impact dish and form; Wherein, a fixing respectively shallow bid of said conduit right ends and an angle board are installed a pointer on the said angle board, and pointer relies on deadweight to be in plumbness all the time; Said pull bar passes the two ends, back and extends outside the conduit from conduit, and fixedly installs respectively in the right ends of said pull bar and to impact dish and draw ring; Said slip cap slidably is nested with between the shallow bid and angle board in the conduit outside, is fixed with the deep bid corresponding with shallow bid on the said slip cap.
For ease of best with the cone match of air port cover, said deep bid and shallow bid are all the frustum with certain taper.
During use with deep bid, shallow bid with impact dish end and insert air port cover centre hole; Through promoting conduit shallow bid at first is close to cover center, air port hole wall, through promoting deep bid and slip cap deep bid also is close to cover center, air port hole wall then, conduit just can not be swung like this; Catheter center and cover center, air port are fitted like a glove; This moment, pointer placed vertical downward direction, through the angle that pointer is read conduit, obtained the actual installation angle of air port cover according to this; The pulling draw ring makes to impact and coils the bump shallow bid when withdrawing from, and makes it loosening and breaks away from cover center, air port hole wall, takes off then to be used for other air ports measurements.
A kind of blast-furnace tuyere angle measurement unit of the utility model compared with prior art; Have following outstanding advantage and beneficial effect: can conveniently measure tuyere cover of blast furnace actual installation angle; Can in time calculate the difference of actual installation angle and design and installation angle, blast furnace operating is had certain directive function.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the use step 1 of the utility model;
Fig. 3 is the use step 2 of the utility model;
Fig. 4 is the use step 3 of the utility model;
Among the figure: 1 conduit, 11 shallow bids, 12 angle boards, 13 pointers, 2 pull bars, 21 impact dish, 22 draw rings, 3 slip caps, 31 deep bids.
Embodiment
As shown in Figure 1, a kind of blast-furnace tuyere angle measurement unit, it by angle board, pointer, conduit, slip cap, deep bid, shallow bid, pull bar and impact the dish form.Conduit 1 is a straight pipe, and a fixing respectively shallow bid 11 of conduit 1 right ends and an angle board 12 are installed a pointer 13 on the angle board, and pointer relies on deadweight to be in plumbness, the change conditions that can read pointer through pointer all the time.Pull bar 2 passes the two ends, back and extends outside the conduit from conduit 1, and fixedly installs respectively in the right ends of pull bar 2 and to impact dish 21 and draw ring 22, and draw ring is the Handheld Division, impacts dish 21 and adopts the mode of nuts to be fixed on the pull bar; Slip cap 3 slidably is nested with between the shallow bid and angle board in conduit 1 outside, is fixed with the deep bid 31 corresponding with shallow bid on the slip cap 3.
As shown in Figure 2, with deep bid, shallow bid with impact dish end and insert air port cover centre hole 4, shallow bid at first is close to cover center, air port hole wall during use through promoting conduit.Then; Like Fig. 3, through promoting deep bid and slip cap deep bid also is close to cover center, air port hole wall, conduit just can not be swung like this; Catheter center and cover center, air port are fitted like a glove; This moment, pointer placed vertical downward direction, through the angle that pointer is read conduit, obtained the actual installation angle of air port cover according to this.Like Fig. 4, the pulling draw ring makes to impact and coils the bump shallow bid when withdrawing from, and makes it loosening and breaks away from cover center, air port hole wall, takes off then to be used for other air ports measurements.
Except that the described technical characterictic of specification sheets, be the known technology of those skilled in the art.
