Description

[Technical field]

[0001] The present invention relates to a sintering equipment inspection device that inspects a sintering equipment that produces sintered ore by heating raw materials for sintered ore while transporting them. In particular, the present invention relates to a sintering equipment inspection device that can accurately inspect a sintering equipment equipped with rails and a slide bed over the entire length from the ore supply side (upstream side in the transport direction) where the raw materials are supplied to the ore discharge side (downstream side in the transport direction) where the sintered ore is discharged. [Background technology]

[0002] FIG. 1 is a diagram showing a schematic configuration of a sintering facility. FIG. 1(a) is a side view (viewed from a horizontal direction perpendicular to the conveying direction) showing the overall configuration of the sintering facility. FIG. 1(b) is a front view (viewed from the conveying direction) showing the vicinity of one pallet cart. FIG. 1(c) is an enlarged view of the area surrounded by the dashed line A in FIG. 1(b). As shown in Fig. 1, the sintering equipment 200 produces sintered ore by transporting raw materials for sintered ore (ore powder, lime powder, and coal powder) from the ore supply side to the ore discharge side in the direction indicated by the thick arrow F in Fig. 1(a) while heating them. In Fig. 1 and the following description, both the raw materials for sintered ore and the sintered ore are denoted by the same symbol S.

[0003] The sintering equipment 200 includes two rails 201 (201a, 201b) arranged parallel to each other, two beams 202 (202a, 202b) supporting each of the two rails 201, a plurality of movable pallet carts 10 arranged on the two rails 201 so as to contact each other in the conveying direction parallel to each rail 201, a power unit 203 that transmits power in the conveying direction to any of the plurality of pallet carts 10, a wind box 204 that is provided below the pallet cart between the two rails 201 and forms a path for sucking in air, and two slide beds 205 (205a, 205b) that are attached to the upper end of the wind box 204 in parallel to each of the rails 201. In the example shown in FIG. 1, the power unit 203 is composed of a sprocket that meshes with the axle 103 of the pallet cart 10 described later. As the sprocket meshing with the axle 103 rotates, power is transmitted in the conveying direction to the pallet cart 10 having this axle 103.

[0004] The sintering equipment 200 also includes a wind leg 206 communicating with the wind box 204, and a main exhaust pipe 207 communicating with the wind leg 206. The wind box 204, the wind leg 206, and the main exhaust pipe 207 form a path for sucking in air. Furthermore, the sintering equipment 200 includes an ore supply section 208 that supplies raw material S of sintered ore to the pallet cart 10, and an ignition furnace 209 that ignites the raw material S. The raw material S supplied to the pallet cart 10 from the ore supply section 208 located upstream in the conveying direction of the raw material S is ignited in the ignition furnace 209 as the pallet cart 10 moves, and then air is sucked in through the wind box 204 and other passages. This causes a sintering reaction in the raw material S, and the sintering reaction spreads from the top to the bottom of the raw material S as the air is sucked in, producing sintered ore S. The produced sintered ore S is discharged from the pallet cart 10 downstream in the conveying direction, and only the pallet cart 10 moves in the direction indicated by the thick arrow R in FIG. 1(a), and the operation of supplying the raw material S of sintered ore from the ore supply section 208 again is repeated.

[0005] The pallet cart 10 has a pallet 101 capable of holding the raw material of sintered ore and the sintered ore S therein, a plurality of wheels 102 that rotate on each rail 201, a plurality of axles 103 that are attached to the pallet 101 and support each of the plurality of wheels 102 rotatably, and two seal bars 105 that are attached to the lower part of the pallet 101 via biasing means 104 such as springs so as to face each of the two slide beds 205 in the vertical direction, and are biased toward each of the slide beds 205 by the biasing means 104. Specifically, the two seal bars 105 are attached to the biasing means 104 provided in a recess formed on the lower surface of the pallet 101. Also, although not shown in the figure, the pallet cart 10 is attached to one of a pair of pallets 101 adjacent to each other in the conveying direction, and has a plate-shaped end liner that contacts the other pallet 101.

[0006] In the sintering equipment 200 having the above-described configuration, the management of the positions of the slide bed 205 and the rail 201 in the vertical direction and the horizontal direction (the horizontal direction perpendicular to the conveying direction) is an issue. For example, if the vertical separation distance between the slide bed 205 and the rail 201 becomes smaller than a predetermined control range determined by the extension limit and contraction limit of the biasing means 104, a gap is generated between the slide bed 205 and the seal bar 105, and air leakage (a phenomenon in which unnecessary air other than the air required for intake in the sintering reaction enters the wind box 204, making it difficult to intake air in the wind box 204) that reduces the productivity of the sintered ore S may occur in the gap. Conversely, if the vertical separation distance between the slide bed 205 and the rail 201 becomes larger than the above-mentioned control range, the seal bar 105 is pressed strongly against the slide bed 205, making the seal bar 105 and the slide bed 205 more likely to wear, and air leakage may occur at the worn points.

[0007] Furthermore, for example, if the horizontal separation distance between the slide bed 205 and the rail 201 exceeds a specified control range (becomes larger or smaller than the specified control range), the seal bar 105 and the slide bed 205 will wear unevenly, and air leakage may occur at the unevenly worn points.

[0008] For the above reasons, the management of the vertical and horizontal positions of the slide bed 205 and the rail 201 is an issue, but generally, the distance from the ore supply side that supplies the raw material S of the sintering equipment 200 to the ore discharge side that discharges the sintered ore S is longer than 100 m. Therefore, in order to measure the vertical and horizontal positions of the slide bed 205 and the rail 201 over its entire length using a general distance measuring device or shape measuring device, it is necessary to stop the operation of the sintering equipment 200 for a long time, and it is not possible to perform the measurement frequently. In particular, in order to measure the vertical and horizontal positions of the slide bed 205 over its entire length, it is necessary to remove all the pallet carts 10 that get in the way during the measurement from the rail 201, which imposes an excessive burden on the measurement.

[0009] For example, Patent Document 1 proposes a device that calculates the center position between two rails using three-dimensional point cloud data that represents the shapes of objects around the rails as a three-dimensional point cloud scanned by a laser scanner installed on a measurement vehicle running on two rails. For example, if the device described in Patent Document 1 is attached to one of the pallet carts 10 of the sintering equipment 200 and the pallet cart 10 is moved, it is considered possible to measure the position of the rail 201 over its entire length. However, since the slide bed 205 is located directly below the pallet 101, it is necessary to take measures to prevent the laser light emitted from the laser scanner from being blocked by the pallet 101. For example, it is possible to process the shape of the pallet 101 so that the laser light is not blocked, but the shape of the pallet 101 is designed to have a strength such that buckling due to compressive stress does not occur, and processing the pallet 101 may cause the pallet 101 to buckle and break. Even if a strength calculation is performed and a design is made so that there are no strength problems, the pallet 101 is generally a cast metal, so it is not easy to manufacture a pallet of a different shape from the normal pallet 101 for holding the raw material for sintered ore and the sintered ore S inside. [Prior art documents] [Patent documents]

[0010] [Patent Document 1] Patent No. 6682087 Summary of the Invention [Problem to be solved by the invention]

[0011] The present invention has been made to solve the problems of the conventional technology as described above, and has an object to provide a sintering equipment inspection device that can accurately inspect sintering equipment equipped with rails and a slide bed over the entire length from the feeding side where raw materials are supplied to the discharge side where sintered ore is discharged. [Means for solving the problem]

[0012] In order to solve the above problem, the inventors focused on an end liner provided between a pair of pallets adjacent in the conveying direction. Since there is no pallet directly below this end liner, they thought that if a sensor for measuring the position of the slide bed or rail is attached to the position of this end liner, the position of the slide bed can be measured over the entire length even if an optical sensor such as a laser scanner described in Patent Document 1 is used, without the light being blocked by the pallet. Therefore, the inventors came up with the idea of ​​attaching a sensor attachment liner to which a sensor can be attached instead of an end liner to one pallet cart, and attaching a sensor for measuring the position of the slide bed or rail to this, and completed the present invention.

[0013] That is, in order to solve the above-mentioned problems, the present invention provides a sintering equipment inspection device for inspecting a sintering equipment that produces sintered ore by heating raw materials for sintered ore while transporting them, the sintering equipment comprising: two rails arranged parallel to each other; two support beams supporting each of the two rails; a plurality of movable pallet carts arranged on the two rails so as to be in contact with each other in a transport direction parallel to the rails; a power unit that transmits power in the transport direction to any one of the plurality of pallet carts; and a power unit that is arranged between the two rails and below the pallet carts. The pallet cart comprises a wind box that constitutes a path for sucking in air, and two slide beds that are attached to the upper end of the wind box in parallel with each of the rails. The pallet cart comprises a pallet capable of holding raw materials for sintered ore and sintered ore inside, a plurality of wheels that rotate on each of the rails, a plurality of axles that are attached to the pallet and support each of the plurality of wheels so as to be freely rotatable, and axles that are attached to the lower part of the pallet via biasing means so as to face each of the two slide beds in the up-down direction, and axles that are biased by the biasing means. The sintering equipment inspection device has two seal bars that are biased toward each of the slide beds, and an end surface liner that is attached to one of the pair of pallets between the pair of pallets adjacent to each other in the conveying direction and contacts the other pallet, and the sintering equipment inspection device has one of the pallet cars having a sensor attachment liner provided in place of the end surface liner, a first sensor attached to the sensor attachment liner and for measuring the position of the slide bed, the support beam and the one rail located on the side of one of the two rails, a second sensor attached to the sensor attachment liner and for measuring the position of the slide bed, the support beam and the other rail located on the side of the other of the two rails, and a calculation unit that calculates the relative positional relationship between the slide bed located on the one rail side and the one rail and the relative positional relationship between the slide bed located on the other rail side and the other rail based on the measurement results of the first sensor and the second sensor, and inspects the sintering equipment based on the calculation result.The present invention provides a sintering equipment inspection device comprising: In addition, in the present invention, "the position of the slide bed, the support beam and the rail" means at least one of the positions in the vertical direction and the positions in the horizontal direction (the horizontal direction perpendicular to the conveying direction). In addition, the "relative positional relationship" in the present invention means at least one of the relative positional relationship in the up-down direction and the relative positional relationship in the horizontal direction (the horizontal direction perpendicular to the conveying direction).

[0014] In the sintering equipment inspection device according to the present invention, one pallet cart has a sensor mounting liner provided in place of an end liner, and a first sensor for measuring the positions of the slide bed, support beam and rail located on one rail side and a second sensor for measuring the positions of the slide bed, support beam and rail located on the other rail side are attached to the sensor mounting liner. Therefore, by moving the pallet cart having the sensor mounting liner, the positions of the slide bed, support beam and rail located on both rail sides can be measured over their entire length by the first sensor and the second sensor. As described above, the positions of the slide bed, support beam, and rail measured are based on the position of the sensor mounting liner (based on one pallet cart to which the sensor mounting liner is attached). For this reason, for example, if the pallet cart meanders horizontally relative to the track, even if the slide bed, support beam, and rail extend straight, the measured positions (horizontal positions) of the slide bed, support beam, and rail will fluctuate horizontally according to the meandering of the pallet cart. Also, if the pallet cart tilts around the conveying direction (moving direction) while moving, the measured positions (vertical positions) of the slide bed, support beam, and rail will fluctuate vertically according to the tilt of the pallet cart.

[0015] However, the relative positional relationship between the slide bed located on one rail side and the rail, and the relative positional relationship between the slide bed located on the other rail side, which are calculated by the calculation unit of the sintering equipment inspection device of the present invention based on the measurement results of the first sensor and the second sensor, can be calculated with high accuracy because the effects of the meandering and tilting of the pallet cart are offset. Therefore, the calculation unit can inspect the sintering equipment over the entire length from the ore supply side to the ore discharge side with high accuracy based on the calculation result. For example, if the vertical distance between the slide bed and the rail, which indicates the vertical relative positional relationship between the slide bed and the rail, exceeds a predetermined control range, or if the horizontal distance between the slide bed and the rail, which indicates the horizontal relative positional relationship between the slide bed and the rail, exceeds a predetermined control range, the calculation unit can determine that there is a risk of air leakage. As described above, according to the sintering equipment inspection device of the present invention, one pallet cart has a sensor mounting liner installed in place of an end liner, and sensors (first sensor, second sensor) for measuring the positions of the slide bed, support beam and rails are attached to this sensor mounting liner.Therefore, by moving this pallet cart, it is possible to accurately inspect the sintering equipment equipped with rails and a slide bed over the entire length from the ore supply side to the ore discharge side.

[0016] Preferably, the calculation unit calculates the relative positional relationship in the vertical direction between the support beam located on the one rail side and the one rail, and the relative positional relationship in the vertical direction between the support beam located on the other rail side and the other rail based on the measurement results of the first sensor and the second sensor, and inspects the sintering equipment based on the calculation results.

[0017] According to the above-mentioned preferred configuration, the calculation unit calculates the relative positional relationship between the support beam and the rail in the vertical direction. For example, the calculation unit can determine that wear of the rail is progressing if the vertical separation distance between the support beam and the rail, which indicates the relative positional relationship between the support beam and the rail in the vertical direction, is equal to or less than a predetermined threshold value.

[0018] Preferably, each of the first sensor and the second sensor includes a first laser rangefinder for measuring the distance to the top surface of the slide bed, a second laser rangefinder for measuring the distance to the side of the slide bed, and an optical cutting type sensor for measuring the cross-sectional shape of the rail and the support beam when viewed from above.

[0019] According to the above preferred configuration, the vertical positions of the slide bed, support beam and rail can be easily measured using the first laser rangefinder and the light cutting sensor, and the horizontal positions of the slide bed, support beam and rail can be easily measured using the second laser rangefinder and the light cutting sensor.

[0020] Preferably, the calculation unit identifies a position in the conveying direction where there is a possibility of air leakage occurring between the slide bed and the seal bar based on a result of the calculation.

[0021] According to the above-described preferred configuration, the calculation unit identifies the position in the conveying direction where air leakage may be occurring, which has the advantage that the operator can take measures such as focusing on inspecting the identified position. In addition, the position in the conveying direction where air leakage may be occurring can be identified, for example, as the position in the conveying direction where the vertical distance between the slide bed and the rail exceeds a specified control range, or where the horizontal distance between the slide bed and the rail exceeds a specified control range. Effect of the Invention

[0022] According to the present invention, it is possible to inspect a sintering facility equipped with rails and a slide bed with high accuracy over the entire length from the ore supply side where raw materials are supplied to the ore discharge side where sintered ore is discharged.

[Diagram 2] 1 is a diagram showing a schematic configuration of a sintering equipment inspection device according to an embodiment of the present invention; [Diagram 3] FIG. 2 is a diagram for explaining an example of an inspection result obtained by the sintering equipment inspection device according to the embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, a sintering equipment inspection device according to one embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 2 is a diagram showing a schematic configuration of a sintering equipment inspection device 100 according to one embodiment of the present invention. FIG. 2(a) is a front view (viewed from the conveying direction) showing the overall configuration of the sintering equipment inspection device 100. FIG. 2(b) is an enlarged view of an area surrounded by a dashed line B in FIG. 2(a). FIG. 2(c) is a diagram explaining the measurement points of a light-cutting type sensor 23 possessed by the sintering equipment inspection device 100. The overall configuration of a sintering equipment to which the sintering equipment inspection device 100 is applied is the same as that of the sintering equipment 200 shown in FIG. 1(a) described above, and the sintering equipment inspection device 100 is disposed in place of one pallet cart 10 of the sintering equipment 200.

[0025] [Overall configuration of sintering equipment inspection device 100] As shown in FIG. 2, the sintering equipment inspection device 100 includes one pallet cart 10 having a sensor mounting liner 11 (a member hatched with dots in FIG. 2) provided in place of an end surface liner. The sintering equipment inspection device 100 is attached to the sensor attachment liner 11 and includes a slide bed 205 (205a) located on one of the two rails 201 (201a, 202b), a support beam 202 (202a), and a first sensor 20 for measuring the position of the one rail 201a. Although detailed illustration of the other rail 201b is omitted, the sintering equipment inspection device 100 is attached to the sensor attachment liner 11 and includes a slide bed 205 (205b) located on the other of the two rails 201 (201a, 202b), a support beam 202 (202b), and a second sensor 30 for measuring the position of the other rail 201b, as with the one rail 201a side shown in FIG. 2(b). Furthermore, the sintering equipment inspection device 100 is equipped with a calculation unit 40 that calculates the relative positional relationship between the slide bed 205a located on the side of one rail 201a and one of the rails 201a, and the relative positional relationship between the slide bed 205b located on the side of the other rail 201b and the other rail 201b based on the measurement results of the first sensor 20 and the second sensor 30, and inspects the sintering equipment 200 based on the calculation results.

[0026] [Pallet Trolley 10] The sensor mounting liner 11 of the pallet cart 10 constituting the sintering equipment inspection device 100 according to this embodiment is attached by screwing or the like to a surface perpendicular to the conveying direction of the pallet 101. As with normal end surface liners, the sensor mounting liner 11 comes into contact with other pallets 101 adjacent in the conveying direction to the pallet 101 to which the sensor mounting liner 11 is attached. The sensor mounting liner 11 of this embodiment is configured to have a sensor mounting liner 11a located on one rail 201a side and a sensor mounting liner 11b located on the other rail 201b side, which are separate from each other. The sensor mounting liner 11a and the sensor mounting liner 11b have the same configuration. However, the present invention is not limited to this, and it is also possible to adopt a configuration in which the one rail 201a side and the other rail 201b side are integrated. The sensor mounting liner 11 has a sensor mounting liner body 111 attached to the pallet 101 and a frame 112 extending from the sensor mounting liner body 111 toward above the rail 201. The configuration of the members of the pallet cart 10 other than the sensor mounting liner 11 is the same as that of the normal pallet cart 10 described with reference to FIG. 1, and therefore a detailed description thereof will be omitted here.

[0027] [First sensor 20] The first sensor 20 has a first laser distance meter 21 for measuring the distance to the upper surface of the slide bed 205 (205a). The first laser range finder 21 of this embodiment is attached to a sensor mounting liner body 111. Specifically, a recess is formed in the sensor mounting liner body 111 in the thickness direction (the moving direction of the pallet cart 10, the direction perpendicular to the paper surface of FIG. 2), and the first laser range finder 21 is fitted and attached in this recess. Since the depth of the recess is set to be equal to or greater than the dimension of the first laser range finder 21 in the thickness direction, there is no risk of the first laser range finder 21 being damaged even if the sensor mounting liner body 111 comes into contact with another adjacent pallet 101. Moreover, the first laser distance meter 21 is attached at a position where there is no seal bar 105 directly below. Specifically, it is attached directly above the seal bar 105 of the pallet cart 10 constituting the sintering equipment inspection device 100 according to this embodiment and the seal bar 105 of the adjacent pallet cart 10. Therefore, the spot-shaped laser light emitted from the first laser distance meter 21 indicated by the dashed arrow in Fig. 2(b) is irradiated onto the upper surface of the slide bed 205 without being blocked by the seal bar 105, and the distance to the upper surface of the slide bed 205 can be measured.

[0028] In this embodiment, as a preferred embodiment, a pair of first laser range finders 21a, 21b arranged side by side in the horizontal direction is attached. Therefore, even if the pallet cart 10 meanders and the laser light emitted from one of the first laser range finders 21 is no longer irradiated onto the upper surface of the slide bed 205, the laser light emitted from the other first laser range finder 21 is irradiated onto the upper surface of the slide bed 205, so that the distance to the upper surface of the slide bed 205 can be reliably measured. The first laser rangefinder 21 described above measures the distance to the top surface of the slide bed 205, in other words, the vertical position of the slide bed 205 (the vertical position based on the position of the sensor mounting liner 11 on which the first laser rangefinder 21 is attached).

[0029] The first sensor 20 also has a second laser distance meter 22 for measuring the distance to the side surface of the slide bed 205 (205a). The second laser rangefinder 22 in this embodiment is attached to the frame 112 so that the emitted spot-shaped laser light (indicated by a dashed arrow in FIG. 2(b)) is irradiated to the side of the slide bed 205 without being blocked. Specifically, the second laser rangefinder 22 is attached to a position on the frame 112 that is off the pallet 101 when viewed from the conveying direction (the direction perpendicular to the paper surface of FIG. 2). Therefore, even if the second laser rangefinder 22 is simply attached to the frame 112 without forming a recess like the above-mentioned sensor mounting liner main body 111, there is no risk of the second laser rangefinder 22 being damaged when a part of the frame 112 comes into contact with another adjacent pallet 101.

[0030] In this embodiment, as a preferred aspect, a pair of second laser range finders 22a, 22b are attached in a vertically juxtaposed manner. Therefore, even if the laser light emitted from one of the second laser range finders 22 is no longer irradiated onto the side surface of the slide bed 205 due to wear of the slide bed 205 or the rail 201, the laser light emitted from the other second laser range finder 22 is irradiated onto the side surface of the slide bed 205, so that the distance to the side surface of the slide bed 205 can be reliably measured. The second laser rangefinder 22 described above measures the distance to the side of the slide bed 205, in other words, the horizontal position of the slide bed 205 (the horizontal position based on the position of the sensor mounting liner 11 on which the second laser rangefinder 22 is attached).

[0031] Furthermore, the first sensor 20 has a light-cutting type sensor 23 for measuring the cross-sectional shapes of the rail 201 (201a) and the support beam 202 (202a) when viewed from above. The sensor 23 in this embodiment is attached to the frame 112. Specifically, the sensor 23 is attached to the tip of the frame 112 that is offset from the pallet 101 when viewed from the conveying direction. Therefore, even if the sensor 23 is simply attached to the frame 112 without forming a recess like the above-mentioned sensor attachment liner main body 111, there is no risk of the sensor 23 being damaged when a part of the frame 112 comes into contact with another adjacent pallet 101. The sensor 23 includes a light source (not shown) that emits a laser beam (indicated by a dashed arrow in Fig. 2(b) and Fig. 2(c)) that extends linearly in the horizontal direction from above in the vertical direction, an imaging means (not shown) that has an optical axis inclined in the conveying direction with respect to the vertical direction and captures the irradiated laser beam to obtain an image, and an image processing means (not shown). The sensor 23 is a sensor for measuring the cross-sectional shape (shape of the part of the rail 201 and the support beam 202 irradiated with the laser beam) of the rail 201 and the support beam 202 when viewed from above, based on the position of the pixel area corresponding to the laser beam in the captured image extracted by the image processing means.

[0032] 2(c), the light-cutting type sensor 23 described above measures the average value of the vertical position of the upper surface 201u of the rail 201 as the vertical position of the rail 201 (the vertical position based on the position of the sensor mounting liner 11 on which the sensor 23 is attached). Also, the average value of the vertical position of the upper surface 202u of the support beam 202 is measured as the vertical position of the support beam 202 (the vertical position based on the position of the sensor mounting liner 11 on which the sensor 23 is attached). Furthermore, the position of the foot edge (outer edge) 201e of the rail 201 is measured as the horizontal position of the rail 201 (the horizontal position based on the position of the sensor mounting liner 11 on which the sensor 23 is attached). In this embodiment, the light-cutting type sensor 23 is provided with an image processing means, and measures the cross-sectional shapes of the rail 201 and the support beam 202, and measures the vertical position of the rail 201, the vertical position of the support beam 202, and the horizontal position of the rail 201 based on the cross-sectional shapes. However, the present invention is not limited to this. The sensor 23 itself may be configured to simply capture the irradiated laser light and obtain the captured image, and the calculation unit 40 electrically connected to the sensor 23 may calculate the cross-sectional shapes of the rail 201 and the support beam 202, the vertical position of the rail 201, the vertical position of the support beam 202, and the horizontal position of the rail 201 based on the captured image input from the sensor 23.

[0033] [Second sensor 30] Like the first sensor 20, the second sensor 30 has a first laser rangefinder 21 for measuring the distance to the top surface of the slide bed 205 (205b), a second laser rangefinder 22 for measuring the distance to the side of the slide bed 205 (205b), and an optical cutting type sensor 23 for measuring the cross-sectional shape of the rail 201 (201b) and the support beam 202 (202b) when viewed from above. The second sensor 30 is attached to the sensor mounting liner 11b located on the other rail 201b side, and has a configuration similar to that of the first sensor 20 attached to the sensor mounting liner 11a located on the one rail 201a side, except that it is configured in a mirror image. Therefore, detailed description thereof will be omitted here.

[0034] It is preferable to attach an imaging means (not shown) for imaging the upper surface of the slide bed 205 between the pair of first laser range finders 21a, 21b constituting the first sensor 20 and the second sensor 30. According to this preferable configuration, for example, when the calculation unit 40 determines that there is a possibility of air leakage between the slide bed 205 and the seal bar 105 as described later, the operator can visually check the image of the upper surface of the slide bed 205 acquired by the imaging means described above, and can infer whether the cause of the air leakage is wear of the slide bed 205 or not.

[0035] [Calculation unit 40] The calculation unit 40 is composed of, for example, a computer electrically connected to the first sensor 20 and the second sensor 30. That is, in this embodiment, the calculation unit 40 is composed of, for example, a computer electrically connected to the first laser distance meter 21, the second laser distance meter 22, and the light-cutting type sensor 23 of the first sensor 20 and the second sensor 30, respectively. The calculation unit 40 stores a program for performing a predetermined calculation and inspection, and performs a predetermined calculation by executing the stored program for the measurement results of the first laser distance meter 21, the second laser distance meter 22, and the light-cutting type sensor 23 input from the first sensor 20 and the second sensor 30, respectively, and inspects the sintering equipment 200 based on the calculation result. The calculation unit 40 is installed, for example, inside the pallet 101.

[0036] An example of the inspection result obtained by the sintering equipment inspection device 100 having the above-described configuration will be described below. Fig. 3 is a diagram for explaining an example of an inspection result by the sintering equipment inspection device 100. Fig. 3(a) shows an example of the vertical positions of the slide bed 205a, the support beam 202a, and the rail 201a measured by the first sensor 20 and input to the calculation unit 40. Fig. 3(b) shows an example of the horizontal positions of the slide bed 205a and the rail 201a measured by the first sensor 20 and input to the calculation unit 40. Fig. 3(c) shows an example of the relative positional relationship between the slide bed 205 and the rail 201 in the vertical direction (the vertical separation distance between the slide bed 205 and the rail 201) calculated by the calculation unit 40. In addition, in Fig. 3(a) and Fig. 3(b), the position of the slide bed 205a is shown by a thick line, and the position of the rail 201a is shown by a thin line. In Fig. 3(a), the position of the support beam 202a is shown by a dashed line. The position in the conveying direction shown on the horizontal axis of Fig. 3 can be calculated by the calculation unit 40, for example, by the product of the preset moving speed of the pallet cart 10 and the elapsed time. In Fig. 3(a) and Fig. 3(b), the vertical axis of the rail 201a and the support beam 202a has the value at the measurement start position as the origin (=0 mm), and the vertical axis of the slide bed 205a has the predetermined reference point of the first laser range finder 21 and the second laser range finder 22 constituting the first sensor 20 as the origin. In Fig. 3(a), the vertical axis has a positive value when it is located above the origin, and a negative value when it is located below the origin. In addition, the vertical axis in Figure 3(b) has positive values ​​when the point is located horizontally inside the origin (left side of Figure 2(b)), and negative values ​​when the point is located horizontally outside the origin (right side of Figure 2(b)).

[0037] 3(a) and 3(b), as the pallet cart 10 moves in the conveying direction, the first sensor 20 attached to the sensor attachment liner 11a also moves in the conveying direction, and the vertical positions of the slide bed 205a, the support beam 202a, and the rail 201a, as well as the horizontal positions of the slide bed 205a and the rail 201a, can be measured over the entire length. Although the measurement results are not shown, as the pallet cart 10 moves in the conveying direction, the second sensor 30 attached to the sensor attachment liner 11b also moves in the conveying direction, and the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b, as well as the horizontal positions of the slide bed 205b and the rail 201b, can be measured over the entire length. The calculation unit 40 can calculate the vertical separation distance (relative positional relationship in the vertical direction) between the slide bed 205a located on the rail 201a side and the rail 201a as shown by the thick line in Fig. 3(c) by performing a difference calculation between the vertical position of the slide bed 205a and the rail 201a shown in Fig. 3(a). Similarly, for the track 201b side, the calculation unit 40 can calculate the vertical separation distance (relative positional relationship in the vertical direction) between the slide bed 205b located on the rail 201b side and the rail 201b as shown by the thin line in Fig. 3(c) by performing a difference calculation between the vertical position of the slide bed 205b and the vertical position of the rail 201b (measurement results are not shown).

[0038] 3(c), if the calculation unit 40 is made to preset and store the lower limit of the control range determined by the extension limit of the biasing means 104 and the upper limit of the control range determined by the contraction limit of the biasing means 104, the calculation unit 40 can determine whether the vertical separation distance between the slide bed 205a and the rail 201a calculated by the difference calculation, or the vertical separation distance between the slide bed 205b and the rail 201b calculated by the difference calculation, exceeds the upper limit or lower limit of the control range. When the vertical separation distance exceeds the control range, the calculation unit 40 can specify the conveying direction position where the distance exceeds the control range (for example, the positions indicated by the arrows X1 and X2 in the example shown in FIG. 3(c)) as the conveying direction position where air leakage may occur between the slide bed 205 and the seal bar 105. In this way, if the calculation unit 40 identifies the position in the conveying direction where air leakage may be occurring, the operator can take measures such as focusing on inspecting the identified position.

[0039] The contents of the inspection by the sintering equipment inspection device 100 (the calculations performed by the calculation unit 40, the contents of the inspection) are not limited to the above, and various modes are possible. For example, the calculation unit 40 can calculate the vertical separation distance (relative positional relationship in the vertical direction) between the support beam 202a located on the rail 201a side and the rail 201a by calculating the difference between the vertical position of the support beam 202a and the vertical position of the rail 201a as shown in Fig. 3(a). Similarly, the calculation unit 40 can calculate the vertical separation distance (relative positional relationship in the vertical direction) between the support beam 202b located on the rail 201b side and the rail 201b by calculating the difference between the vertical position of the support beam 202b and the vertical position of the rail 201b. If a predetermined threshold value is set and stored in advance in the calculation unit 40, the calculation unit 40 can determine whether the vertical separation distance between the support beam 202a and the rail 201a calculated by the difference calculation, or the vertical separation distance between the support beam 202b and the rail 201b calculated by the difference calculation, is equal to or less than the threshold value. If the vertical separation distance is equal to or less than the threshold value, the calculation unit 40 can determine that wear of the rail 201a or the rail 201b is progressing.

[0040] As described above, according to the sintering equipment inspection device 100 of this embodiment, one pallet cart 10 has a sensor mounting liner 11 provided in place of an end liner, and a first sensor 20 and a second sensor 30 for measuring the positions of the slide bed 205, the support beam 202 and the rail 201 are attached to this sensor mounting liner 11.Therefore, by moving this pallet cart 10, the sintering equipment 200 can be accurately inspected over its entire length from the ore supply side to the ore discharge side.
