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. Furthermore, for example, if the horizontal separation distance between the two rails 201 is equal to or greater than a predetermined threshold value, operational problems such as the wheels 102 coming off the rails 201 may occur.

[0008] For the reasons described above, 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 the entire length using a general distance measuring device or shape measuring device, it is necessary to suspend the operation of the sintering equipment 200 for a long period of time, and there is a problem that measurements cannot be performed frequently.

[0009] For example, Patent Document 1 proposes an optical cutting type device for measuring the cross-sectional shape of a rail. 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 positions of the rails 201, etc. over the entire length. However, since it is unclear to what position on the rail 201 the pallet trolley 10 will move, and the pallet trolley 10 may tilt around the conveying direction (movement direction), a configuration in which the device described in Patent Document 1 is simply attached to one pallet trolley 10 makes it impossible to accurately measure the vertical and horizontal positions of the slide bed 205 and the rail 201.

[0010] [Patent Document 1] Japanese Patent Application Publication No. 6-341819 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 have focused on using a total station capable of measuring the distance and angle to a target. By attaching targets to one rail side and the other rail side of one pallet cart, respectively, and installing a total station at a predetermined position outside the pallet cart, and measuring the distance and angle to each target (i.e., the position of each target based on the predetermined position where the total station is installed), it is possible to calculate the position (position in the conveying direction, horizontal position perpendicular to the conveying direction) and inclination (inclination around the conveying direction) of the pallet cart based on the predetermined position. Therefore, the inventors have come up with the idea that by attaching a sensor for measuring the position of the slide bed and rail to the pallet cart and combining the measurement result of the sensor with the position of the target measured by the total station (in other words, the position and inclination of the pallet cart based on the predetermined position), the position of the slide bed and rail (position based on the predetermined position) can be calculated with high accuracy without being affected by the position and inclination of the pallet cart (so that the influence of the position and inclination of the pallet cart is offset), and have 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 of the plurality of pallet carts; a wind box that is provided below the pallet cart between the two rails and forms a path for sucking in air; and two slide beds that are attached to the upper end of the wind box and parallel to each of the rails, the pallet cart comprising a pallet capable of holding raw materials for sintered ore and sintered ore therein; a plurality of wheels that rotate and move on each of the rails; a plurality of axles that are attached to the pallet and rotatably support each of the plurality of wheels; and a pallet cart that is arranged so as to face each of the two slide beds in the up-down direction, and two seal bars each attached to a lower part of a slide bed via a biasing means and biased toward each of the slide beds by the biasing means, wherein the sintering equipment inspection device comprises one of the pallet carts, a first sensor attached to the pallet cart and for measuring the positions of the slide bed, the support beam and the one of the rails located on one of the two rails, a second sensor attached to the pallet cart and for measuring the positions of the slide bed, the support beam and the other rail located on the other of the two rails, a total station installed at a predetermined position outside the pallet cart, a first target attached to the one of the rails of the pallet cart, a second target attached to the other of the rails of the pallet cart, and a calculation unit that inspects the sintering equipment based on the measurement results of the first sensor and the second sensor and the positions of the first target and the second target measured by the total station. 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, in the present invention, "the positions of the first target and the second target" means at least one of the positions in the up-down direction and the positions in the horizontal direction (the horizontal direction perpendicular to the transport direction), and the positions in the transport direction.

[0014] In the sintering equipment inspection device according to the present invention, a first sensor for measuring the positions of the slide bed, the support beam and the rail located on one rail side and a second sensor for measuring the positions of the slide bed, the support beam and the rail located on the other rail side are attached to one pallet cart. Therefore, by moving this pallet cart, the positions of the slide bed, the support beam and the rail located on both rail sides can be measured over their entire length by the first sensor and the second sensor. The positions of the slide bed, the support beam, and the rail measured as described above are positions based on the pallet cart to which the first and second sensors are attached. For this reason, for example, if the pallet cart meanders horizontally relative to the track, even if the slide bed, the support beam, and the rail extend straight, the measured positions (horizontal positions) of the slide bed, the support beam, and the 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, the support beam, and the rail will fluctuate vertically according to the tilt of the pallet cart.

[0015] However, a pallet cart to which a first sensor and a second sensor are attached has a first target attached to one rail side and a second target attached to the other rail side, and the positions of the first target and the second target are measured by a total station installed at a predetermined position outside the pallet cart. If the positions of the first target and the second target (the positions of the first target and the second target based on the predetermined position where the total station is installed) are measured by the total station, it is possible to calculate the position (position in the conveying direction, position in the horizontal direction perpendicular to the conveying direction) and tilt (tilt around the conveying direction) of the pallet cart based on the predetermined position. The calculation unit provided in the sintering equipment inspection device of the present invention inspects the sintering equipment based on the measurement results of the first and second sensors (the positions of the slide bed, support beam and rail with respect to the pallet cart) and the positions of the first and second targets measured by the total station (in other words, the position and inclination of the pallet cart with respect to a predetermined position). Therefore, the calculation unit can accurately calculate the positions of the slide bed and rail (positions with respect to a predetermined position) without being affected by the position and inclination of the pallet cart (so that the effects of the position and inclination of the pallet cart are offset), and can accurately inspect the sintering equipment based on this calculation result. As described above, according to the sintering equipment inspection device of the present invention, sensors (first sensor, second sensor) for measuring the positions of the slide bed, support beams and rails are attached to one pallet cart, and targets (first target and second target) whose positions are measured by a total station installed at a predetermined position outside the pallet cart are attached.Therefore, by moving this pallet cart, it is possible to accurately inspect the sintering equipment equipped with rails and slide bed over the entire length from the ore supply side to the ore discharge side.

[0016] 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.

[0017] 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.

[0018] Preferably, the calculation unit calculates the vertical positions of the two rails and the vertical positions of the two slide beds based on the specified position, and the amount of meandering of the two rails and the amount of meandering of the two slide beds based on the specified position, based on the measurement results of the first sensor and the second sensor and the positions of the first target and the second target measured by the total station, and inspects the sintering equipment based on the calculation results.

[0019] According to the above-mentioned preferred configuration, the calculation unit calculates the vertical positions of the two rails and the vertical positions of the two slide beds based on a predetermined position (i.e., not affected by the position or inclination of the pallet cart). Also, the meandering amount (amount of change in horizontal position) of the two rails and the meandering amount of the two slide beds based on the predetermined position are calculated. For example, if the vertical distance between the slide bed and the rail, calculated from the vertical positions of the slide bed and the rail, exceeds a predetermined control range, the calculation unit can determine that there is a risk of air leakage. Also, if the horizontal distance between the slide bed and the rail, calculated from the meandering amount of the slide bed and the meandering amount of the rail, exceeds a predetermined control range, the calculation unit can determine that there is a risk of air leakage.

[0020] Preferably, the calculation unit calculates the vertical separation distance between the two rails and the horizontal separation distance perpendicular to the conveying direction, based on the specified position, and the vertical separation distance between the upper surfaces of the two slide beds and the horizontal separation distance perpendicular to the conveying direction, based on the specified position, based on the measurement results of the first sensor and the second sensor and the positions of the first target and the second target measured by the total station, and inspects the sintering equipment based on the calculation results.

[0021] According to the above-mentioned preferred configuration, the calculation unit calculates the vertical separation distance between the two rails and the horizontal separation distance perpendicular to the conveying direction, based on a predetermined position (i.e., not affected by the position or inclination of the pallet cart). Also, the calculation unit calculates the vertical separation distance between the upper surfaces of the two slide beds and the horizontal separation distance perpendicular to the conveying direction, based on a predetermined position. For example, if the horizontal separation distance between the two rails is equal to or greater than a predetermined threshold value, the calculation unit can determine that there is a risk of operational trouble, such as wheels coming off the rails. Also, if the vertical separation distance between the two rails or the vertical separation distance between the upper surfaces of the two slide beds exceeds a predetermined control range, one of the slide beds becomes more susceptible to wear, and the calculation unit can determine that there is a risk of air leakage. Furthermore, if the horizontal separation distance between the upper surfaces of the two slide beds exceeds a predetermined control range, the contact area between the seal bar and the slide bed becomes smaller, and the calculation unit can determine that there is a risk of air leakage.

[0022] Preferably, the calculation unit calculates the inclination of the upper surfaces of the two rails with respect to the specified position and the inclination of the upper surfaces of the two support beams with respect to the specified position based on the measurement results of the light-cutting type sensors of the first sensor and the second sensor and the positions of the first target and the second target measured by the total station, and inspects the sintering equipment based on the calculation results.

[0023] According to the above-mentioned preferred configuration, the calculation unit calculates the inclination of the upper surfaces of the two rails based on a predetermined position (i.e., not affected by the position or inclination of the pallet cart). Also, the calculation unit calculates the inclination of the upper surfaces of the two support beams based on a predetermined position. For example, if the inclination of the upper surface of the rail or the upper surface of the support beam is above a predetermined threshold value, the pallet trolley is more likely to meander, and the calculation unit can determine that there is a risk of operational problems such as air leakage or wheel derailment.

[0024] 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.

[0025] 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 transport direction where air leakage may be occurring can be identified, for example, as the position in the transport direction where the vertical distance between the slide bed and the rail, calculated from the vertical position of the slide bed and the vertical position of the rail, exceeds a specified control range, or where the horizontal distance between the slide bed and the rail, calculated from the amount of meandering of the slide bed and the amount of meandering of the rail, exceeds a specified control range. Effect of the Invention

[0026] 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.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] 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 an embodiment of the present invention. FIG. 2(a) is a plan view showing the overall configuration of the sintering equipment inspection device 100. FIG. 2(b) is a front view (viewed from the conveying direction) showing an enlarged overall configuration of the sintering equipment inspection device 100. FIG. 2(c) is an enlarged view of the area surrounded by the dashed line B in FIG. 2(b). FIG. 3 is a diagram explaining the measurement points of the light-cutting type sensor 23 of the sintering equipment inspection device 100. The overall configuration of the sintering equipment to which the sintering equipment inspection device 100 is applied is the same as the sintering equipment 200 shown in FIG. 1(a) above, and the sintering equipment inspection device 100 is arranged instead of one pallet cart 10 of the sintering equipment 200. In FIG. 2(a), only one pallet cart 10 constituting the sintering equipment inspection device 100 is illustrated for convenience, but in reality, there are multiple pallet carts 10 adjacent to this pallet cart 10 in the conveying direction.

[0029] [Overall configuration of sintering equipment inspection device 100] As shown in Fig. 2, the sintering equipment inspection device 100 includes one pallet cart 10. Unlike the other pallet carts 10 included in the sintering equipment 200, this pallet cart 10 has a structure that allows a first sensor 20 and a second sensor 30, which will be described later, to be attached. In a preferred embodiment, this pallet cart 10 includes a sensor attachment liner 11 (a member hatched in dots in Fig. 2) that is 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(c).

[0030] The sintering equipment inspection device 100 also includes a total station 40 installed at a predetermined position outside the pallet cart 10 (a position that does not change during operation of the sintering equipment 200). The total station 40 is a surveying instrument that emits a spot-shaped laser beam (indicated by a dashed arrow in FIG. 2(a)) toward a target and can measure the distance and angle to the target. The configuration of the total station 40 is similar to that of a known total station, so a detailed description thereof will be omitted here. The sintering facility inspection device 100 also includes a first target 50 attached to one rail 201a side of the pallet cart 10, and a second target 60 attached to the other rail side 201b of the pallet cart 10. Furthermore, the sintering equipment inspection device 100 is equipped with a calculation unit 70 that inspects the sintering equipment 200 based on the measurement results of the first sensor 20 and the second sensor 30 and the positions of the first target 50 and the second target 60 measured by the total station 40.

[0031] [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.

[0032] [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 Figs. 2(b) and 2(c)), 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(c) 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.

[0033] 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).

[0034] 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 range finder 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(c)) is irradiated to the side of the slide bed 205 without being blocked. Specifically, the second laser range finder 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 FIGS. 2(b) and 2(c)). Therefore, even if the second laser range finder 22 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 second laser range finder 22 being damaged when a part of the frame 112 comes into contact with another adjacent pallet 101.

[0035] 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).

[0036] 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. 3) 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.

[0037] 3, 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 70 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.

[0038] [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.

[0039] 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 70 judges 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, and can infer whether the cause of the air leakage is wear of the slide bed 205 or not.

[0040] [Total Station 40] As shown in FIG. 2(a), the total station 40 of this embodiment is installed on an overbridge 210 that spans from one rail 201a to the other rail 201b above the pallet cart 10 of the sintering equipment 200. In this embodiment, as a preferred aspect, a pair of total stations 40 (total station 40a for measuring the position of a first target 50 described below, and total station 40b for measuring the position of a second target 60 described below) are installed. The total station 40a measures the position of the first target 50 (the vertical position, horizontal position, and conveying direction position based on a predetermined position where the total station 40a is installed), and the total station 40b measures the position of the second target 60 (the vertical position, horizontal position, and conveying direction position based on a predetermined position where the total station 40b is installed).

[0041] [1st target 50, 2nd target 60] The first target 50 is attached to one rail 201a side of the pallet cart 10. The first target 50 in this embodiment is attached to a position adjacent to the first sensor 20 inside the pallet 101. The second target 60 is attached to the other rail 201b side of the pallet cart 10. The second target 60 in this embodiment is attached to a position inside the pallet 101 near the second sensor 30. As the first target 50 and the second target 60, a reflecting prism that reflects the laser light emitted from the total station 40 in the same direction as the direction of emission but in the opposite direction is preferably used.

[0042] [Calculation unit 70] The calculation unit 70 is composed of, for example, a computer electrically connected to the first sensor 20, the second sensor 30, and the total station 40. That is, in this embodiment, the calculation unit 70 is composed of, for example, 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, and a computer electrically connected to the total stations 40a and 40b. The calculation unit 70 stores a program for performing a predetermined calculation and inspection, and performs a predetermined calculation by executing the stored program on 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 the positions of the first target 50 and the second target 60 input from the total stations 40a and 40b, respectively, and inspects the sintering equipment 200 based on the calculation results. The calculation unit 70 is installed, for example, inside the pallet 101.

[0043] An example of the inspection result obtained by the sintering equipment inspection device 100 having the above-described configuration will be described below. 4 and 5 are diagrams for explaining an example of the inspection result by the sintering equipment inspection device 100. FIG. 4(a) shows an example of the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b measured by the second sensor 30 and input to the calculation unit 70, and the vertical position of the second target 60 measured by the total station 40b and input to the calculation unit 70. FIG. 4(b) shows an example of the horizontal positions of the slide bed 205b and the rail 201b measured by the second sensor 30 and input to the calculation unit 70, and the horizontal position of the second target 60 measured by the total station 40b and input to the calculation unit 70. FIG. 5(a) shows the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b calculated by the calculation unit 70 based on the measurement result shown in FIG. 4(a) and based on a predetermined position where the total station 40b is installed. Figure 5(b) shows the amount of meandering (amount of change in horizontal position) of the slide bed 205b and the rail 201b, based on the specified position where the total station 40b is installed, calculated by the calculation unit 70 based on the measurement results shown in Figure 4(b). In addition, in Fig. 4 and Fig. 5, the position of the slide bed 205b is shown by a thick line, and the position of the rail 201b is shown by a thin line. In Fig. 4, the position of the second target 60 is shown by a thick line. Furthermore, in Fig. 4(a) and Fig. 5(a), the position of the support beam 202b is shown by a dashed line. The position in the conveying direction shown on the horizontal axis of Fig. 4 and Fig. 5 corresponds to the position in the conveying direction of the second target 60 measured by the total station 40b and input to the calculation unit 70. In Fig. 4(a) and Fig. 4(b), the vertical axis of the rail 201b, the support beam 202b, and the second target 60 has the value at the measurement start position as the origin (=0 mm), and the vertical axis of the slide bed 205b has the predetermined reference point of the first laser range finder and the second laser range finder constituting the second sensor 30 as the origin. In Fig. 4(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 of Fig. 4(b) has a positive value when it is located horizontally inside the origin (the right side of Fig. 2(b)) and a negative value when it is located horizontally outside the origin (the left side of Fig. 2(b)). The origins of the vertical axes of Fig. 5(a) and Fig. 5(b) are the same as the origins of the vertical axes of Fig. 4(a) and Fig. 4(b), respectively.

[0044] As shown in Figure 4, as the pallet trolley 10 moves in the conveying direction, the second sensor 30 attached to the sensor mounting liner 11b also moves in the conveying direction, making it possible to measure 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 over their entire length. The calculation unit 70 can calculate the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b based on a predetermined position as shown in Fig. 5(a) by calculating the difference between the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b shown in Fig. 4(a) and the vertical position of the second target 60. In other words, it is possible to calculate the vertical positions of the slide bed 205b, the support beam 202b, and the rail 201b that are not affected by the position or inclination of the pallet cart 10. The calculation unit 70 can calculate the horizontal positions of the slide bed 205b and the rail 201b based on a predetermined position as shown in Fig. 5(b) by calculating the difference between the horizontal positions of the slide bed 205b and the rail 201b and the horizontal position of the second target 60 as shown in Fig. 4(b). That is, the horizontal positions of the slide bed 205b and the rail 201b can be calculated without being affected by the position or inclination of the pallet cart 10.

[0045] Although the measurement results are not shown in the figure, as the pallet trolley 10 moves in the conveying direction, the first sensor 20 attached to the sensor mounting liner 11a also moves in the conveying direction, making it possible to measure 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 over their entire length. Then, by calculating the difference between the vertical positions of the slide bed 205a, the support beam 202a, and the rail 201a and the vertical position of the first target 50, it is possible to calculate the vertical positions of the slide bed 205a, the support beam 202a, and the rail 201a with respect to a predetermined position as a reference, similar to the result shown in Fig. 5(a). In other words, it is possible to calculate the vertical positions of the slide bed 205a, the support beam 202a, and the rail 201a that are not affected by the position or inclination of the pallet cart 10. 5(b), it is possible to calculate the horizontal positions of the slide bed 205a and the rail 201a with respect to a predetermined position as a reference by performing a difference calculation between the horizontal positions of the slide bed 205a and the rail 201a and the horizontal position of the first target 50. In other words, it is possible to calculate the horizontal positions of the slide bed 205a and the rail 201a that are not affected by the position or inclination of the pallet cart 10.

[0046] The calculation unit 70 can calculate the vertical separation distance between the slide bed 205b and the rail 201b by further calculating the difference between the vertical position of the slide bed 205b and the vertical position of the rail 201b shown in Fig. 5(a). Similarly, for the track side 201a, the calculation unit 70 can calculate the vertical separation distance between the slide bed 205a and the rail 201a by further calculating the difference between the vertical position of the slide bed 205a and the vertical position of the rail 201a. If the calculation unit 70 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 70 can determine whether the vertical separation distance between the slide bed 205a and the rail 201a calculated by the above difference calculation, or the vertical separation distance between the slide bed 205b and the rail 201b calculated by the above difference calculation, exceeds the upper limit or lower limit of the control range. If the vertical separation distance exceeds the control range, the calculation unit 70 can specify the conveying direction position where the distance exceeds the control range as a 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 70 specifies the conveying direction position where air leakage may occur, the operator can take measures such as inspecting the specified position intensively.

[0047] The contents of the inspection by the sintering equipment inspection device 100 (the calculation performed by the calculation unit 70, the contents of the inspection) are not limited to the above, and various modes are possible. 6A and 6B are diagrams for explaining another example of the inspection results by the sintering equipment inspection device 100. Fig. 6A shows an example of the vertical separation distance between the two rails 201a, 201b, the vertical separation distance between the upper surfaces of the two slide beds 205a, 205b, and the vertical separation distance between the two support beams 202a, 202b, calculated by the calculation unit 70 based on the measurement results of the first sensor 20 and the second sensor 30 and the positions of the first target 50 and the second target 60 measured by the total station 40, with the predetermined position where the total station 40 is installed as the reference. Specifically, Figure 6(a) shows an example of the vertical separation distance between the two rails 201a, 201b, with the predetermined position where the total station 40 is installed as the reference, and the upward direction of the rail 201b as positive and the downward direction of the rail 201b as negative; the vertical separation distance between the upper surfaces of the two slide beds 205a, 205b, with the predetermined position where the total station 40 is installed as the reference, and the upward direction of the slide bed 205b as positive and the downward direction of the slide bed 205b as negative; and the vertical separation distance between the two support beams 202a, 202b, with the predetermined position where the total station 40 is installed as the reference, and the upward direction of the support beam 202b as positive and the downward direction of the support beam 202b as negative. Figure 6(b) shows an example of the horizontal separation distance between the two rails 201a, 201b and the horizontal separation distance between the upper surfaces of the two slide beds 205a, 205b, calculated by the calculation unit 70 based on the measurement results of the first sensor 20 and the second sensor 30 and the positions of the first target 50 and the second target 60 measured by the total station 40, based on a specified position where the total station 40 is installed. Specifically, Figure 6(b) shows an example of the horizontal separation distance between the two rails 201a, 201b, with the horizontal direction of the rail 201b indicated as positive and negative, based on a specific position where the total station 40 is installed, and the horizontal separation distance between the upper surfaces of the two slide beds 205a, 205b, with the horizontal direction of the slide bed 205b indicated as positive and negative, based on a specific position where the total station 40 is installed.

[0048] The vertical separation distance between the two rails 201a, 201b based on a predetermined position can be calculated by calculating the difference between the vertical positions of the rails 201a, 201b based on the predetermined position. The vertical separation distance between the upper surfaces of the two slide beds 205a, 205b based on a predetermined position can be calculated by calculating the difference between the vertical positions of the slide beds 205a, 205b based on the predetermined position. The vertical separation distance between the two support beams 205a, 205b based on a predetermined position can be calculated by calculating the difference between the vertical positions of the support beams 205a, 205b based on the predetermined position. In addition, the horizontal separation distance between the two rails 201a, 201b based on a predetermined position can be calculated by calculating the difference in the horizontal positions of the rails 201a, 201b based on the predetermined position. The horizontal separation distance between the upper surfaces of the two slide beds 205a, 205b based on a predetermined position can be calculated by calculating the difference in the horizontal positions of the slide beds 205a, 205b based on the predetermined position. In addition, in Fig. 6(a) and Fig. 6(b), the calculated value for the slide bed 205 is shown by a thick line, and the calculated value for the rail 201 is shown by a thin line. In Fig. 6(a), the calculated value for the support beam 202 is shown by a dashed line. The position in the conveying direction shown on the horizontal axis of Fig. 6 corresponds to the position in the conveying direction of the midpoint of the first target 50 and the second target 60 measured by the total station 40 and input to the calculation unit 70. The vertical axis of Fig. 6(a) is a positive value when the rail 201b, the support beam 202b, and the slide bed 205b are located above the rail 201a, the support beam 202a, and the slide bed 205a, respectively, and a negative value when they are located below. The vertical axis of Fig. 6(b) is a positive value when the horizontal separation distance between the two rails 201a and 201b becomes larger than the origin, and a negative value when it becomes smaller.

[0049] For example, if a predetermined threshold value is set and stored in the calculation unit 70, the calculation unit 70 can calculate the horizontal separation distance between the two rails 201a and 201b based on a predetermined position as shown in FIG. 6(b) and determine whether the calculated separation distance is equal to or less than the threshold value. If the calculated separation distance is equal to or more than the threshold value, the calculation unit 70 can determine that an operational trouble such as the wheel 102 coming off the rail 201 may occur. If a predetermined control range is set and stored in the calculation unit 70, the calculation unit 70 can calculate the horizontal separation distance between the upper surfaces of the two slide beds 205a and 205b based on a predetermined position as shown in FIG. 6(b) and determine whether the calculated separation distance exceeds the predetermined control range. If the calculated separation distance exceeds the control range, the calculation unit 70 can determine that there is a risk of air leakage because the contact area between the seal bar 105 and the slide bed 205 is small. Similarly, if a predetermined control range is set and stored in advance in the calculation unit 70, the calculation unit 70 can calculate the vertical separation distance between the two rails 201a, 201b and the vertical separation distance between the two slide beds 205a, 205b, as shown in Fig. 6(a), with a predetermined position as the reference, and determine whether or not the calculated separation distance exceeds the predetermined control range. If the calculated separation distance exceeds the control range, the calculation unit 70 can determine that one of the slide beds 205 is prone to wear, and therefore there is a risk of air leakage.

[0050] FIG. 7 is a diagram for explaining another example of the inspection result by the sintering equipment inspection device 100. FIG. 7 shows an example of the inclination of the upper surface of the rail 201b and the inclination of the upper surface of the support beam 202b, calculated by the calculation unit 70 based on the measurement result of the light-cutting type sensor of the second sensor 30 and the positions of the first target 50 and the second target 60 measured by the total station 40, with the predetermined position where the total station 40 is installed as a reference. Specifically, FIG. 7 shows an example of the result of correcting the inclination of the upper surface of the rail 201b and the inclination of the upper surface of the support beam 202b calculated from the measurement result of the light-cutting type sensor of the second sensor 30 by the inclination of the pallet 101 calculated from the positions of the first target 50 and the second target 60 measured by the total station 40. In Fig. 7, the inclination of the upper surface of the rail 201b is indicated by a solid line, and the inclination of the upper surface of the support beam 202b is indicated by a dashed line. The position in the transport direction indicated on the horizontal axis of Fig. 7 corresponds to the position in the transport direction of the second target 60 measured by the total station 40b and input to the calculation unit 70. On the vertical axis of Fig. 7, the inclination of the upper surface of the rail 201b and the inclination of the upper surface of the support beam 202b at the measurement start position are set as the origin (=0°), and a positive value is used when the upper surface is inclined so that the horizontal outer side (left side of Fig. 2(b)) is higher than the origin, and a negative value is used when the upper surface is inclined so that the horizontal outer side is lower than the origin.

[0051] For example, if a predetermined threshold value is preset and stored in the calculation unit 70, the calculation unit 70 can calculate the inclination of the upper surfaces of the two rails 201a, 201b and the upper surfaces of the two support beams 202a, 202b with respect to a predetermined position as a reference, as shown in Fig. 7, and determine whether or not the calculated inclination is equal to or less than the threshold value. If the calculated inclination is equal to or more than the threshold value, the pallet cart 10 is likely to meander, and therefore the calculation unit 70 can determine that there is a risk of operational trouble such as air leakage or wheel loss.

[0052] As described above, according to the sintering equipment inspection device 100 of this embodiment, the first sensor 20 and the second sensor 30 for measuring the positions of the slide bed 205, the support beam 202 and the rail 201 are attached to one pallet cart 10, and the first target 50 and the second target 60 whose positions are measured by the total station 40 installed at a predetermined position outside the pallet cart 10 are attached. Therefore, by combining the measurement results of the first sensor 20 and the second sensor 30 with the positions of the first target 50 and the second target 60 measured by the total station 40, it is possible to accurately calculate the positions of the slide bed 205 and the rail 201 (positions based on a predetermined position) without being affected by the position or inclination of the pallet cart 10 (so that the influence of the position and inclination of the pallet cart 10 are offset), and by moving this pallet cart 10, it is possible to accurately inspect the sintering equipment 200 over the entire length from the ore supply side to the ore discharge side.
