  FIG. 1 is a perspective view schematically showing an automatic combustion chamber temperature measuring device for a coke oven according to an embodiment of the present invention.

  As shown in FIG. 1, a coke oven combustion chamber temperature automatic measuring device 100 according to an embodiment of the present invention is attached to a first rail so as to cross a running direction of a charging vehicle 13 of a coke oven 11. A first slider 20 that is movably attached along the first rail portion 10 and travels along the length direction of the first rail portion 10 by driving of the first motor 23, and the first rail portion 10. The second rail portion 34 is attached to the first slider 10 in a direction intersecting the first slider 10, and is attached to the combustion chamber 18 of the coke oven 11 along the second rail portion 34 so as to be movable up and down, and travels by driving the second motor 28. The second slider 30, the position sensor 40 that is attached so as to move with the movement of the second slider 30, and senses the position of the combustion chamber lid 15, and the second slider 3. When the sensing signal of the position sensor 40 is transmitted, the clamping unit 50 that selectively clamps the lid 15 that opens and closes the combustion chamber 18, and the clamping state of the lid 15 by the clamping unit 50, When the opening operation of the lid 15 by the movement of the second slider 30 is performed, a temperature measuring device 60 that measures the temperature in the combustion chamber is included.

  2 is a perspective view of the coke oven automatic combustion chamber temperature measuring device of FIG. 1 as viewed from another direction. FIG. 3 is a first slider and a first slider of the coke oven automatic combustion chamber temperature measuring device of FIG. It is a principal part figure which shows the structure of 2 slider.

  As shown in FIGS. 2 and 3, the first rail portion 10 is attached so as to cross the traveling direction A of the charging vehicle 13. The first rail portion 10 is attached to the charging vehicle 13 in a state separated from the lid 15 by a certain distance from the upper portion of the combustion chamber. Such a first rail portion 10 is extended between one side and the other side of the loading vehicle 13 for the movement of the first slider 20 described later.

  The first rail portion 10 includes a first beam 12 attached so as to cross the traveling direction of the loaded vehicle, and a first traveling rail 14 attached along the length direction of the first beam 12.

  The first beam 12 can be attached in the form of a square beam that supports the first rail portion 10. A heat sink part 16 may be formed on a side surface of the first beam 12 so as to withstand a high temperature generated from the uptakes 19 at the upper part of the combustion chamber or the combustion chamber. The ascending pipe 19 refers to a portion where hot gas moves. The heat sink part 16 can be formed by a combination of a plurality of recesses and protrusions drawn inside on the side surface of the first beam 12. The heat sink portion 16 is formed on the side surface of the first beam 12 in the direction in which the rising tube 19 is viewed or in the combustion chamber direction. However, the heat sink portion 16 is not limited to one position on the side surface of the first beam 12, but may be formed in the entire peripheral region of the first beam 12 or a part of the selected side surface.

  The first traveling rail 14 is attached to the upper side of the first beam 12 with a length corresponding to the length of the first beam 12. The first traveling rail 14 is attached in a state of protruding from the upper side of the first beam 12, and the sliding operation of the first slider 20 is performed. The first slider 20 includes a roller 29. The roller 29 can be attached to a concave roller having a concave shape in contact with the first traveling rail 14. Therefore, the first traveling rail 14 protrudes in a convex shape so that the protruding shape is easily coupled to the roller 29. Here, when the roller 29 is not a concave roller but a square roller is applied, the protruding shape of the first traveling rail 14 is naturally changed to a square shape. The first traveling rails 14 can be formed on the upper side and the lower side of the first beam 12, respectively. This is for the purpose of performing a stable sliding operation of the first slider 20 on the first traveling rail 14. Such rolling driving of the roller 29 will be described in more detail while explaining the first slider 20. A rack gear 16 is attached in the length direction of the first beam 12.

  The rack gear 16 is attached to transmit the sliding driving force of the first slider 20.

  FIG. 4 is a cross-sectional view of the main part showing attachment of the first slider to the first beam.

  As shown in FIG. 4, the first slider 20 is attached to a bracket 21 slidably attached to the first beam 12, a first motor 23 attached to the bracket 21, and a drive shaft of the first motor 23. And a pinion gear 27 that meshes with the rack gear 16 and transmits a driving force.

  The bracket 21 is slid on the upper side of the first beam 12 to form a mounting space therein, and the first motor 23, the roller 29, and the pinion gear 27 are mounted. The bracket 21 can be bent and extended so as to cover the upper side of the first beam 12 in order to attach and protect the first motor 23, the roller 29, and the pinion gear 27.

  As for the 1st motor 23, a main-body part is attached to the bracket 21, and the drive shaft 25 is attached so that it may go to the 1st beam 12 direction. A pinion gear 27 is attached to the drive shaft 25 of the first motor 23. The pinion gear 27 meshes with the rack gear 16 of the first beam 12 and transmits the driving force of the first motor 23. As a result, the first slider 20 is slidingly driven by the meshing drive of the rack gear 16 and the pinion gear 27. The roller 29 is attached to the bracket 21 so as to be able to roll, and is driven to roll on the first traveling rail 14. The roller 29 performs a stable sliding operation by a guide action when the first slider 20 is sliding. Therefore, a plurality of rollers 29 can be attached to the upper side and the lower side of the first beam 12 via the first beam 12. In the embodiment of the present invention, the number of rollers 29 can be three respectively on the upper side and the lower side. However, for stable guide action and appropriate selection of the structural layout, the number of rollers 29 is It is possible to change without limitation.

  Such sliding operation of the first slider 20 moves as the operator performs the operation of the charging vehicle, and moves to the position of the lid 15 at the upper part of the combustion chamber. That is, when the loading drive of the loading vehicle is performed, the operation signal is transmitted to the first motor 23, and the sliding drive of the first slider 20 is performed. The first slider 20 stops when the position of the combustion chamber lid 15 is sensed by the operation of a position sensor 40 described later. Next, the second slider 30 is lowered at the stop position of the first slider 20 so that the clamping operation of the combustion chamber lid 15 is performed. The second slider 30 is slid along the second beam 22.

  The second rail portion 34 is attached to the bracket 21 of the first slider 20 in a direction intersecting with the first rail portion 10. That is, the second rail portion moves as the first slider 20 moves horizontally.

  FIG. 5 is a side view schematically showing the second rail portion and the second motor, and FIG. 6 is a view cut along the line V-V in FIG. 5.

  As shown in FIGS. 5 and 6, the second rail portion 34 includes a second beam 22 that is movably attached in a direction crossing the first beam 12, and a length direction of the second beam 22. And a second traveling rail 31 attached thereto. Reference numeral “21 a” represents a mounting bracket for mounting the second rail portion 34.

  The second beam 22 is attached to the bracket 21 in a direction crossing the first beam 12. The second beam 22 and the first beam 12 intersect with each other perpendicularly to drive the second beam 22. The mounting angle of the second beam 22 is to smoothly perform the clamping operation of the lid 15 in conjunction with the sliding operation. That is, the second beam 22 moves up and down perpendicular to the lid direction, and the clamping operation of the lid 15 can be performed with less force. The clamping operation of the lid 15 will be described in more detail while explaining a clamping unit 50 described later.

  A heat sink portion 24 is formed on the side surface of the second beam 22 so as to prevent deformation of the second beam 22 due to the high heat of the riser 19. The heat sink part 24 is formed by a combination of a concave part and a protrusion part drawn into the side surface of the second beam 22. The heat sink portion 24 formed on the second beam 22 may be formed only on the ascending tube side, or may be formed over the entire circumference without being limited to one side surface of the second beam 22.

  A rack gear 26 is attached in the length direction of the second beam 22. The rack gear 26 meshes with the pinion gear 23 attached to the drive shaft of the second motor 28 attached to the bracket 21. Therefore, the second beam 22 is slid in the direction of the lid 15 by driving the second motor 28. The driving of the second motor 28 is driven so as to lower the second beam 22 when the position sensor 40 is operated and the sensing operation of the lid 15 is performed. A second traveling rail 31 is attached to the second beam 22.

  The second traveling rail 31 is attached so as to protrude from the side surface of the second beam 22. The second traveling rails 31 can be attached in pairs along the length direction of the second beam 22 on both sides of the second beam 22. The second beam 22 is guided by a rolling drive of a roller 32 attached to the bracket 21 and is moved up and down. The roller 32 can be attached to a concave roller having a concave contact surface. Of course, when the roller 32 is applied to a concave roller, the second traveling rail 31 protrudes in a concave shape. A second slider 30 is attached to the tip of the second beam 22.

  FIG. 7 is a diagram schematically showing attachment of the second slider and the clamping sensor.

  As shown in FIG. 7, the second slider 30 includes a connection bar 37 attached to the end of the second beam 22 and a lifting body 33 attached to the connection bar 37.

  One end of the connection bar 37 is connected to the end of the second beam 22, and the other end is extended in the horizontal direction to the first beam 12. The connecting bar 37 moves up and down in the direction of the lid 15 as the second beam 22 slides. The connecting bar 37 is attached in a bar shape or a bar shape having corners. The elevating body 33 is attached to the other extended end of the connecting bar 37. A clamp sensor 35 that senses the clamping operation of the lid 15 is attached to the elevating body 33.

  The clamping sensor 35 includes an elevating bracket 35a attached to the elevating body 33, an elevating body 35b attached to the end of the connecting bar 37, and slidably attached to the elevating bracket 35a, and the elevating body 35b and the elevating bracket 35a. And a load cell 35c attached therebetween.

  The raising / lowering bracket 35a is attached to the raising / lowering body 33 so that raising / lowering is possible. In order to mount the lifting bracket 35a so that it can be lifted and lowered, a long hole-shaped coupling hole 35d is formed on the side surface of the lifting bracket 35a. A coupling protrusion 35e protruding from the elevating body 35b is inserted into the coupling hole 35d. A hooking portion is formed at the end of the coupling protrusion 35e to prevent the coupling with the lifting bracket 35a from being released. Thereby, the raising / lowering operation of the raising / lowering bracket 35a is performed corresponding to the length of the coupling hole 35d.

  A load cell 35c is attached between the elevating bracket 35a and the elevating body 35b. The load cell 35c is attached to the upper side of the elevating body 35b and senses contact and release according to the relative movement of the elevating bracket 35a and the elevating body 35b, and senses whether the lid 15 and the clamping unit 50 are in contact with each other. To do.

  Hereinafter, the sensing operation of the lid of the clamping sensor using the load cell 35c will be described in more detail.

  First, as shown in FIG. 9, when the lid 15 is sensed via the position sensor 40, the second beam 22 is lowered by driving the second motor 28.

  Next, as shown in FIG. 9b, the second slider 30 descends as the second beam 22 descends, and as shown in FIG. 9c, the clamping unit 50 contacts the lid 15. The descent operation stops.

  Next, as shown in FIG. 9c, the lowering operation of the elevating bracket 35a connected to the clamping unit 50 is also stopped, and the elevating body 35b continues the lowering operation for a certain distance by the inertia force in the lowering direction. Done. The lowering of the elevating body 35b is limited to the length of the long hole 35d.

  Next, the contact between the load cell 35c on the upper side of the elevating body 35b and the elevating bracket 35a is released. Thereby, the load cell 35c generates a change in pressure, and can easily sense the contact between the clamping unit 50 and the lid 15.

  As described above, when the clamping unit 50 is lowered, when the position of the lid 15 is sensed using the position sensor 40, the clamping unit 50 is lowered.

  The position sensor 40 is attached to the lifting body 33 of the second slider 30. The position sensor 40 can be composed of a magnetic sensor. That is, the magnetic sensor is operated by magnetic lines of force, and when the lid 15 is positioned below the magnetic sensor, a sensing operation of the lid 15 is performed by sensing fluctuations of the magnetic lines of force. When the accurate position of the lid 15 is sensed by such sensing of the position sensor 40, the elevating body 33 of the second slider 30 is lowered and the clamping unit 50 clamps the lid 15.

  FIG. 8 is a diagram illustrating the clamping unit viewed from the bottom surface of the lifting body.

  As shown in FIG. 8, the clamping unit 50 is attached to the bottom surface of the elevating body 33 by an electromagnet. One or two or more electromagnets of the clamping unit 50 can be attached to the bottom surface of the elevating body 33. When the operation of the clamping unit 50 is determined to be in contact with the lid 15 by sensing of the clamping sensor 35, the lid 15 is clamped by the magnetizing action of the electromagnet when the power is applied.

  When the clamping operation of the lid is completed, the clamping unit 50 is moved to one side. That is, the first motor 23 is driven to move the first slider 20, and the lid 15 is moved to open the combustion chamber 18. Next, the temperature in the combustion chamber is measured via the temperature measuring device 60 attached to the elevating body 33.

  The temperature measuring device 60 includes a protruding bracket 61 protruding from the side surface of the elevating body 33 and a pyrometer 63 attached to the protruding bracket 61 and remotely measuring the temperature in the combustion chamber.

  One end of the protruding bracket 61 is attached to the side surface of the elevating body 33 or the elevating bracket 35 a, and the other end can be attached to the outside of the elevating body 33. The protruding bracket 61 protrudes in a plate shape so that the pyrometer 63 is attached to the outside of the elevating body 33 while being separated.

  The action of the pyrometer 63 refers to a thermometer that measures color and intensity and senses temperature by utilizing the fact that when a high-temperature object becomes high temperature, heat radiation becomes strong and changes from red to incandescent color. Such a pyrometer 63 can easily measure the temperature remotely without directly contacting the high-temperature measurement object. Therefore, since the temperature in the combustion chamber of the coke oven can be measured remotely with the combustion chamber 18 opened, accurate temperature measurement and the occurrence of a safety accident can be prevented. The elevating body 33 is attached with a cooler 70 that protects the pyrometer 63 from the high temperature of the combustion chamber.

  The cooler 70 is attached to the elevating body 33, and an air injection nozzle 70 (the same reference number as the cooler) for injecting the cooling air 71 is attached. The air injection nozzle 70 injects the cooling air 71 onto the bottom surface of the pyrometer 63 so that the action of the air curtain is performed. Therefore, damage is not caused by preventing the high temperature of the combustion chamber from being directly transmitted to the pyrometer 63.

  On the other hand, a foreign matter remover 80 for removing foreign matters outside the lid 15 is attached to the clamping unit 50.

  The foreign matter remover 80 is attached to the bottom surface of the elevating body 33 and includes an air blower 80 (reference number is the same as the foreign matter remover) that injects air toward the lid 15. Thus, before the clamping operation of the lid 15 using the clamping unit 50, the air 81 is sprayed onto the lid 15 to remove foreign matters on the surface of the lid 15, so that the clamping operation is performed smoothly. To do.

  Hereinafter, an operation of the automatic combustion chamber temperature measuring device for a coke oven according to an embodiment of the present invention having the above-described configuration will be described.

  First, an operator inputs a measurement point of a combustion chamber of a coke oven to be measured.

  Next, the first slider 20 moves along the first rail portion 10. Such movement of the first slider 20 is performed by the driving force of the first motor 23.

  Next, as shown in FIG. 9, the measurement point of the combustion chamber set in advance via the position sensor 40 that moves as the first slider 20 moves, that is, the combustion chamber lid to be measured. Sense the position of.

  Next, when the position of the lid of the measurement point is sensed via the position sensor 40, air is injected to the lid at the measurement position using an air blower 80 as shown in FIG. Thereby, the foreign material on the upper side of the lid 15 is removed.

  Then, as shown in FIG. 11, when the second slider 30 is lowered, the clamping unit 50 and the lid 15 are brought into contact with each other. Here, the contact between the lid 15 and the clamping unit 50 is sensed via the clamping sensor 35.

  Next, as shown in FIG. 12, when the contact sensing signal of the lid 15 of the clamping sensor 35 is transmitted, the electromagnet of the clamping unit is magnetized and the clamping action of the lid 15 is performed.

  Next, the second slider 30 moves to the upper side of the lid 15 to remove the lid 15 from the combustion chamber so that the combustion chamber is opened.

  Next, as shown in FIG. 13, the second slider 30 moves a certain distance along the first rail portion 10 so that the pyrometer 63 moves to the position of the combustion chamber. Here, when the pyrometer 63 is moved, air from the air injection nozzle 70 is injected to prevent the pyrometer 63 from being damaged due to the high temperature of the combustion chamber 12.

  Next, the pyrometer 63 automatically and remotely measures the temperature in the combustion chamber. Therefore, it is possible to measure the temperature of the combustion chamber accurately and without causing a safety accident by replacing the temperature measurement of the combustion chamber by the operator's manual work.
