Such applications, for example, S彳 b X J疋 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里 里The application in special hard conditions is used in the steel industry by θ I and the wheel container. , measuring 1 molten pig iron or steel reformer for workability and high energy due to Xin, 栌 — 5 10 15 to the processing - wide processing. The genus is often transported from a production system. In the steel industry, the liquid pig iron is brought from the blast furnace to the reformer using a suitable container (generally called Γ; Γ) and it is regarded as a praying waste. Specifically, it is a continuous praying machine, a raw material processed in iron milling. These can accommodate hundreds of mouthpieces and the same day:: The shape of the steel drum has a lining. The lining is constructed-insulated. The steel sleeve of the inner:::r... is not affected by the melt. In the steel conversion = 9 ray-shaped steel drums, the lining suffered wear and tear, and the result was in a special installation: ^ individual plaque burst. Since such damage can seriously affect the status of the king and the land, the general situation of such transport equipment must be regularly checked, corrected or replaced, which of course leads to high costs. At the time of this inspection, the torpedo-shaped steel drum (or any other container for steel or iron) must be cooled and must be slowly warmed to the operating temperature (approx. 00 C). XI causes considerable disruption to the job, resulting in high costs. SUMMARY OF THE INVENTION The present invention provides an apparatus capable of accurately measuring the internal space of one of the containers. By using the reference record before the initial operation (data stored in a memory) and by forming a difference from the corresponding actual record, it is possible to accurately determine the change in the lining due to wear and brick burst. Therefore, the repair of the lining will only be carried out when it is really needed. 1334922 According to the present invention, the present invention proceeds to a stem that is supported on a support. Furthermore, 'providing' is arranged as a mirror unit that is stationary relative to the measuring head, by which the mirror unit is offset from the incident beam in a radial direction and vice versa, one of which is stationary 5 early 7L shots can be broken by the axial guidance associated with the hollow shaft, and can be transmitted by the mirror unit in a radial direction, and the mirror reflected from the object in the object space is conditioned by the mirror unit It can be deflected in the direction of the axis of the hollow shaft and can be transported to a receiving unit that is also stationary. Of course, the mirror unit can be constructed in a number of ways, for example by a 10 reflection! Brother and / or all or part of the reflection prism. For example, one optical system shared by the transmitter channel and the receiver channel has a coaxial arrangement, and the channels can be divided, for example, by a part of transparent mirrors, a single mirror or a corresponding 稜鏡. It is enough. However, in an advantageous further development of the present invention, the apparatus includes a rotational measurement of a motor-driven cymbal 15 2 positioned between the legs of a seat and supported on a hollow shaft, two of which The mirror is fixed in the measuring head in an axial direction relative to the hollow shaft, and a first mirror causes the emitting unit or a light guide to be inserted into the beam of the hollow shaft in an axial direction to be opposite to the The null = axis is offset in the radial direction and transmits the equal wave I (preferably in beamforming) while the second mirror is incident substantially parallel to the emitter beam and is sub-. The beam reflected by the object within the object space is offset in the axial direction relative to the hollow axis (preferably offset after beamforming) toward the receiving unit, optionally incorporating a light guide. In an advantageous manner, the support is, as is known per se, mounted on a shaft 1334492 = = an axis extending directly to the axis of rotation of the measuring head to enable the measuring system to pass through the narrow passage (for example, a container for injection 5 10 15 20 , 2nd space, according to one of the advantages of the invention, on a preferably cylindrical support tube, the second direction is the same as the axis of the support tube and preferably the same as the latter. When the steel drum or other glazed metal container, especially for the container of molten steel, can be substantially carried out at the operating temperature, it is no longer required to specifically cool the container. Preferably, the support and / or the skill or measuring head includes a material that is configured for this purpose, specific to the system, cooled by liquid, and / or with - insulation, for the support and / or the mouth of the cold & liquid The #1 and the discharge system shall be carried out by the official who conducts the inside of the support pipe. - In this way, for the first time, it is possible to use this cooling configuration and/or the insulation, ie, the 1 - part of the grain and the corresponding downtime Cost. Therefore, these (some) measurements, even mirrors The construction and arrangement and the measurement of the material must be regarded as its own invention. Moreover, it has been hitherto that the technician has been working to arrange the measuring head outside the container to be tested, otherwise on the other hand In an advantageous manner, the measuring head can additionally or alternatively be cooled by a gas C comprising an evaporative cooling medium such as Fre 〇n, the specific f is pressured. The air is cooled, for example, via the hollow, the side is introduced into the measuring head and can be discharged via the other side, and the gas supply is carried out through a conduit inside the branch pipe, and the gas can pass through the 11 1334922 The support tube is discharged. In order to protect the introduction and guidance of the rotatably supported measuring system, the protection range 5 10 15 is entered into the measuring device, and the measuring beam is derived from the inactive position. The window is oriented towards "two: where the contours adapted to the support are introduced, for example two: into: the contour of the contour is shaped by the analog. y into - spherical dome or in addition / then in the system, unified The protection can be violated by the support and measurement of the following position. In the case of no effect, the second tube can be directly obtained in the stepped shape of the branch pipe standard tube, and the stepped diameter of the first support and the measuring head Between the heart: Close the support, the turntable and the measuring head. In the evening, the branch pipe together with the support and the surveyor can be moved to - relative to the object to be tested 1 2 The invention has a container (4) and (4) a container and a liquid tank truck for the purpose of invading molten metal. (4) Knowing the beam whenever the measuring beam is emitted from the measuring head in a radial direction, and is supported by the support and the turntable. Shading occurs in one of the areas surrounding the building pipe or the like (shad 〇wing) Since the measuring system is usually introduced into the container via the injection neck of the container, this means that the measuring system is only in the area where the melt flows at a high flow rate when the filling neck is filled and/or discharged. Blocked (bUnd)' Therefore, we must assume that there is the greatest wear phenomenon here. In order to avoid the shadowing phenomenon and also to be able to measure in the critical area, according to the present invention, the front of the mouth is arranged. Each of the mirrors, the intrusion and the derivation of the measurement beam is offset in a substantially tangential direction. The scope of the invention is related to the measurement beam of the measurement head.

In addition, in order to check the torpedo-shaped steel drum, a measuring head 8 is injected into the hollowed-out package by injecting into the neck. The measuring head 8 is disposed in the inner tube of the tube 9 and the extension 1G of the tube is displaceably supported on the carrier; the free end of the f 15 Π: Η) has a casing which accommodates a laser ranging The electronic unit of the instrument and the control unit of the scanning device of the measuring head 8. Within the tubes 9, 10, the data transfer material, the control line and the power double line are guided to the measuring head 8. The laser emitter or transmitting station s, the photoelectron receiving E for the laser echo pulse, and the entire evaluation unit for switching between the two are arranged in the housing 12' and coupled via a glass fiber line 64 (Fig. 4) Connected to the measuring head 8: According to this, the evaluation unit can be understood to be referred to by reference numeral 。 2. Inside the official 9, 10 there is also a conduit for cooling the cooling medium of the appropriate measuring head 8 and/or a Pressurized air duct. The entire set of equipment is controlled by a control and data transmission cable 13, which is connected to an electronic computer c, which measures the measured data (as it is determined by the evaluation unit 12) in an online or offline state. A model is known, and a 3D cable 14 that is conveniently stored inside the model 1 is labeled as 14 - the memory of the magazine. A power 5 10 but the supply and discharge of the medium; It is indicated as 15, and the cold tool is introduced into the torpedo shaped steel drum with a shot of 16.

If the system is not in the form of a mechanical A reference point:::copper:: may be measured by measuring the head 8 during the measurement. Λ Rotate. As can be seen in Figure 1, the tube 9 is surrounded by the conical area because the measuring beam hits the base portion 24 of the measuring skirt (Fig. == arranged here; see Figures 2 and 4a) and cannot reach the entire internal space by (4) torpedo After the completion of the shape of the shop 1 τ cool "Shi Ba direction of the rotation of the measuring head 8 way record - mother - individual data elements, will be derived from the distance value and the simultaneous judgment of 20 1334922 due to the beam deviation caused by the scanning device Space coordinates. By the sum of all the data elements, a 3D model of the internal space of the steel drum 1 can be established. If there is an older record of one of the torpedo shaped steel drums 1, it can be calculated by forming a difference. Any change in the surface of the lining. This older recorded data is directly compared to the measured data from the measuring head 8 in a memory, such as a computer C memory, or in the measured data. The comparison is made in the memory of the computer c. ίο 15 The construction of the measuring device is depicted in an axial section in Figure 2. The measuring head 8 comprises a cylindrical outer casing 28 with respect to the axis 27. Used in the jacket A substantially rectangular window 29 for measuring and receiving waves is received. Within the housing 28, behind the window 29 are two lenses 3, 31 for measuring beams (collimating lenses for transmitting beams and for reflecting echo signals). Focusing lens. The weight of these glass elements 29 to 31 is compensated by a counterweight 32 arranged in the outer ridge 2 den. The outer casing 28 is rotatable about the axis 27. The measuring raft 8 is supported at the end 33 of a hollow shaft 33 '34. This two-axis end, 34 is supported and guided by the bearing 35,% which is outlined green in the figure. Then the measuring head 8 is driven by a motor river, and the pinion 37 of the motor is sprayed on one The wall of the outer casing 28 is coaxially mounted on the inner gear 辋 38 of the hollow shaft. Alternatively, the outer gear system is driven to drive the measuring head 8 and the opening is available for driving. When measuring, the measuring head 8 is guided by an arrow. The direction of the buckle is turned into a circle. The emission is sent to the measuring head by the -glass fiber _9 = guided by a counter mirror 40 and enters the inner head through the hollow shaft in the axial direction, and the surface 41 is reflected by the hollow shaft. The (4) is thus sent to the collimator 20 1334922 mirror 30. From a target The light reflection of the body reflection is incident on the measuring head 8 through the window 29, and is concentrated by the focusing lens above the glass fiber material after being double-shifted by the reflecting surface 42 and the mirror 43. The (4) line will further echo signals. Further guided to the receiving unit of the range finder, the 5 seats 21, 22, 24 and their two legs 21 and 22 are arranged on a turntable 45. The turntable 45 performs a reciprocating motion in the direction of the arrow 47. When the broom has a full space angle, the angle is at least 8 〇, preferably 3 6 〇. For this reason, it is internally drawn by a dotted line with a toothed roller. The motor Ml drives. The toothed roller tr^ is combined with one point.

10 rounds ig. The mountain < n W support 2 22 22, 24 legs 21 and 22 and the turntable 45 are surrounded by a = 11 48 and / or - insulation layer 49, and the insulation is covered by a piece of metal sleeve Surrounded by 50. Water or even oil can be used as a cooling medium. In the case of extreme temperature loads, the measuring head 8 can be additionally equipped with an air cooling system, for example, a gas, such as Fre〇n, or with a pressurized air, but in the case of a small temperature load. It can also be used for individual use; For this reason, in the case of the present embodiment, the uncharged air ducts in the figure are guided into the legs 22 of the bearings 21, 22, 24, and the legs are connected in a manner not shown. To the end of the hollow shaft. The charge air = (or any other gas) flows through the measuring head 8 at a relatively high speed and exits the measuring head 8 via the hollow shaft end 34 and is then discharged through the legs 21 of the bearings 21, 22. In order to obtain by air or gas - optimal cooling effect, the guides are arranged inside the measuring head. As in the above embodiment, the Geguoliang beam is emitted from the measuring head in the radial direction by 17 1334922 and enters in the radial direction, which causes a large spatial angle to be obscured 2 5 , that is, the measured beam does not reach this point. This area is obscured by the base 24 of the supports 21, 22, 24 and the turntable 45. 5 10 Figure 3 shows an overview of how to reduce this shadowing effect or to completely avoid this shadowing effect with the appropriate configuration of the measuring head. In accordance with the present invention, a 稜鏡52 replacement window 29 is provided, the surface 53 of which is made reflective. The measuring beam of the measuring head of this embodiment does not enter and exit in a radial direction but in a substantially tangential manner. If the cymbal 52 is constructed such that the distance 54 of the inner boundary 55 of the measuring beam 56 is at least equal to the radius of the base 24 or the turret 45 of the pedestal 21, 22, 24, no shadowing effect will occur. When the turret 45 pivots the pedestals 21, 22, 24 together with the measuring head 8 18 〇, the 稜鏡 52 and the measuring beam 56 will be in the positions indicated by the dashed lines (52, and 56,). With a measuring device modified in this way, even an area where one of the injection/frozen ports 2 15 weeks is subjected to extreme stress can be inspected. According to the present invention, the measuring device is subjected to stress in a plurality of faces when applied to a steel product, particularly when measuring a lining of a torpedo-shaped steel drum. First of all, there is a special working temperature of about 30 (the high working temperature of rc. When the measuring system is introduced into the steel ladle, there is a possibility of 20 collision with the inner wall of the injection neck 2, steel granules from the furnace wall, slag Or the liner may become loose and may contaminate the port 29 or prism 52 and/or damage the entire measuring device. A measuring device is schematically depicted in Figures 4a and 4b, partially in section, which is protected in a wide range. In order to prevent the above-mentioned dangers during the key section of the guide torpedo-shaped steel drum i. Each of the legs 21 and 22 is surrounded by a cooling sleeve of a zigzag shaped small copper tube 57. The cooling jacket is _ The barrier layer 18 1334922 49 is covered and the insulation layer is surrounded by a sheet metal sleeve 50. The holders 21, 22, 24 are mounted on a turntable 45 which is also cooled by a small copper tube 57 and is - The heat insulating layer 49 is surrounded. The turntable 45 is fixed to one of the flanges 58 of the tube 1 , and the s-tube has a liquid cooling layer and a heat insulating layer. The cooling heat insulating tube is thinned together with the 5 turntable 45. The wall-like metal tube 9 is covered. A tube 59 is detachably fitted over the tube 9 and the holders 21, 22, 24. In the inactive position of the star system, the tube 59 takes the position shown in Figure 4a; and in the active position 'the tube 59 is at least retracted to the turntable 45 (see Figure 4b). When the system is disconnected, borrow The measuring head 8 is moved by the control unit to the position shown in Figures 4a 1 and 4b. The tube 59 and the driver of the measuring head 8 are only switchable when the measuring head is retracted in the tube 59. The mode is electrically locked against each other. Another option is 'When the driver of the measuring head is turned on but the tube is not retracted, a position sensor that cooperates with the tube 59 sends a signal. In this case, 'sensing' The signal of the device will be sent to a finger 15 that reminds the user to retract the tube 59, or the tube will be translated by a servo motor that is automatically activated by the sensor signal until the tube is in the retracted position. The two legs 21 and 22 of the brackets 21, 22, 24 shown in Fig. 4b preferably have shoulder steps in the plane 60. The free ends of the legs 21 and 22 and the upper half 61 of the measuring head 8 It is shaped into a half ball. When the 20-volume system is introduced into the torpedo-shaped steel drum!, the measuring head 8 is in the position shown in Figure 4 and 4b. The officer 59 is translated in the previous direction according to Fig. 4a so that the sensitive measuring head is protected in a wide range. By measuring the spherical shape of the free end of the configuration, the different container has an extremely narrow opening, and the operation of introducing into the container is substantially helpful. The free end of the arrangement can also be shaped into a certain 1343492 elliptical shape, leading to the measuring head, to the turn 4 4 5 and to the cooler are guided by the cooled tube 9; for the supports 21, 22 2, the supply of cooling medium with the wire and the return conduit are marked as 62, the control line of the _45 5 8 and the turntable 45, the power material and the data line are marked with the standard 63, the fiberglass to and from the measuring head The cable is marked as . 2 Mark the cooling medium supply conduit to the cooling device of tube 9 or 10. 10 [Simple description of the diagram] Figure 1 shows a schematic diagram of a torpedo-shaped steel drum.
