Description

1 DESCRIPTION Title of Invention: SUPPORT STRUCTURE FOR TRIPPER COUPLED TO STACKER, AND TRAVELING CARGO HANDLING DEVICE Technical Field [0001] The present invention relates to a support structure for a tripper coupled to a stacker, and a traveling cargo handling device, the stacker and the traveling cargo handling device being used when carried bulks, such as coals or iron ores, (hereinafter referred to as "carried bulks") transferred by, for example, a yard conveyor are stacked on a yard,. Background Art [0002] Conventionally, for example, in a cargo handling equipment at a pier, or an ironworks, the carried bulks, such as coals or iron ores to be carried in, are stacked on a yard 3 to be stored, and a traveling cargo handling device used for this stowage is widely known. As shown in Fig. 7, a stacker 2 included in a traveling cargo handling device 1 includes: a traveling machine body 5 configured to travel on rails 4 extending along the yard 3; a slewing superstructure 6 provided on the traveling machine body 5 so as to be slewable; and a boom 7 supported by the slewing superstructure 6 so as to be luffable. [0003] A yard conveyor 8 for carry-in and carry-out is laid between the rails 4. A tripper 9 is provided so as to pull a belt of the yard conveyor 8 obliquely upward and cause the carried bulks to fall down from an upper end of the belt. The tripper 9 is coupled to the traveling machine body 5 and transfers the carried bulks to a boom conveyor 10 provided at the boom 7. The carried bulks transferred to the boom conveyor 10 as above are conveyed to a tip end side of the boom 7, dropped on the yard 3, and stacked in a truncated cone shape or a cone shape.

2 [0004] The stacker 2 and the tripper 9 shown in Fig. 7 are separate structures and each configured to stand on its own. To be specific, the stacker 2 includes the traveling machine body 5, the slewing superstructure 6 provided on the traveling machine body 5, and the boom 7 supported by the slewing superstructure 6 so as to be elevatable. A counter weight beam 11 extending in a direction opposite to a direction in which the boom 7 extends is provided at a base end portion of the boom 7. [0005] The tripper 9 includes: a tripper traveling bogie 12 provided so as to be movable on the rails 4; a tripper support frame 13 provided on the tripper traveling bogie 12; and a tripper main body 9a provided on the tripper support frame 13. [0006] As another example of the traveling cargo handling device configured such that each of this type of stacker and this type of tripper stands on its own, a stacker reclaimer is disclosed in PTL 1. Citation List Patent Literature [0007] PTL 1: Japanese Laid-Open Patent Application Publication No. 2001-58725 Summary of Invention Technical Problem [0008] As shown in Fig. 7, the boom 7 included in the stacker 2 is provided with the counter weight beam 11. When the counter weight beam 11 passes under the tripper 9 by the slewing of the boom 7, the counter weight beam 11 needs to be prevented from contacting the tripper support frame 13 and the tripper traveling bogie 12. Therefore, the counter weight beam 11 needs to be formed such that a length Li thereof becomes comparatively small. The counter weight beam 11 includes a counter weight 11a for 3 adjusting a weight balance of the boom 7. [0009] In a case where the counter weight beam 11 is formed such that the length Li thereof becomes comparatively small as above, the weight of the counter weight 11 a needs to be increased in order to set the moments to be equal to each other. Therefore, the strengths of the counter weight beam 11 and other structures configured to support the counter weight beam 11 need to be increased. On this account, the cost increases, and a period of time required to manufacture the stacker 2 increases. [0010] To prevent the counter weight beam 11 from contacting the tripper support frame 13 and the like when the boom 7 slews, the tripper support frame 13 and the like may be arranged at positions away from the stacker 2. However, in a case where the tripper support frame 13 and the like are arranged at positions away from the stacker 2, left end portions of the tripper support frame 13 and the like shown in Fig. 7 get close to the position of the center of gravity of the tripper 9, and an overhang amount of the tripper 9 relative to the tripper support frame 13 increases. Thus, the stability decreases. [0011] Further, as shown in Fig. 7, in order to cause the tripper 9 to stand on its own, the tripper support frame 13 and the tripper traveling bogie 12 each having a strength capable of independently supporting the tripper 9 are necessary. Therefore, the cost for the tripper 9 increases, and a period of time required to manufacture the tripper 9 increases. [0012] The present invention was made to solve the above problems, and an object of the present invention is to provide a support structure for a tripper coupled to a stacker, and a traveling cargo handling device, the support structure and the traveling cargo handling device being configured such that a counter weight beam can be formed so as to be comparatively long, and the weight of the counter weight beam, and therefore, the 4 weights of a traveling stacker and a tripper can be reduced. Solution to Problem [0013] A support structure for a tripper coupled to a stacker according to the present invention is a support structure for a tripper coupled to a stacker, the support structure including: a stacker main body configured to travel on rails; and the tripper coupled to the stacker main body and configured to travel on the rails together with the stacker main body, wherein the stacker main body supports a tip end portion of the tripper. [0014] The support structure for the tripper coupled to the stacker according to the present invention is configured such that the tip end portion of the tripper is coupled to and supported by the coupling support portion of the stacker main body. Therefore, a tripper leg portion configured to support the tripper and cause the tripper to move on the rails can be provided at a position away from the traveling stacker and reduced in size. On this account, the counter weight beam can be prevented from contacting the tripper leg portion when the counter weight beam passes under the tripper by the slewing of the boom. As a result, the counter weight beam can be formed so as to become comparatively long. The counter weight beam includes a counter weight configured to accessorily adjust the balance of the boom. [0015] In the support structure for the tripper coupled to the stacker according to the present invention, the stacker main body may include a slewing frame provided via a lower slewing support portion so as to be slewable, the slewing frame may be provided with a boom, and the tip end portion of the tripper may be provided at an upper portion of the slewing frame via an upper slewing support portion. [0016] With this, the weight of the tripper on the stacker main body side can be 5 supported by the upper slewing support portion, the slewing frame, and the lower slewing support portion. Since the slewing frame is supported by the lower slewing support portion so as to be slewable, and the tip end portion of the tripper is provided at the upper portion of the slewing frame via the upper slewing support portion, the boom provided at the slewing frame can be caused to freely slew together with the slewing frame without being restricted by a lower portion of the stacker main body at which the lower slewing support portion is provided, and the tripper. [0017] In the support structure for the tripper coupled to the stacker according to the present invention, a coupling support portion configured to support the tip end portion of the tripper at the stacker main body may have a pin connected structure in which the tip end portion of the tripper is supported so as to be swingable about a tripper support pin arranged horizontally. [0018] With this, a relative displacement of the tripper generated between the tripper and the stacker main body when the tripper bends by, for example, the weights of the tripper and the carried bulks on the tripper is acceptable by the pin connected structure. Thus, in the configuration including the tripper, the stacker main body, the upper slewing support portion, and the lower slewing support portion, a force, such as a moment, acting on respective slewing support portions based on the above relative displacement can be reduced or eliminated. [0019] In the support structure for the tripper coupled to the stacker according to the present invention, a boom may be provided at the stacker main body so as to be slewable, and an upper portion of the boom may be suspended from the stacker main body via a boom support pin such that the boom is luffable. [0020] With this, when the boom is caused to luff about the boom support pin in the elevating direction, the center of this luffing operation can be caused to be located at 6 an upper portion of the boom. Thus, in a case where a center of gravity (a center of gravity of the boom and the like) of the total of the weights of the boom, a boom conveyor, and the carried bulks conveyed by the boom conveyor is located at the upper portion of the boom, a center position of the luffing operation of the boom can be caused to get close to the position of the center of gravity of the boom and the like. As a result, a movement distance of the position of the center of gravity of the boom and the like in the horizontal direction when the boom is caused to luff can be reduced, and a force, such as a moment, acting on the stacker main body by the weights of the boom and the like by the movement of the position of the center of gravity of the boom and the like in the horizontal direction can be reduced. With this, a force generated by a luffing driving device configured to, for example, cause the boom to luff in the elevating direction can be made low, and the cost for the luffing driving device can be reduced. [0021] In the support structure for the tripper coupled to the stacker according to the present invention, the boom may be arranged so as to be inserted through the slewing frame, an upper portion of the boom may be suspended from the slewing frame via a boom support pin such that the boom is luffable, and an inspection walkway may be formed on a side surface of the boom. [0022] In a case where the boom support pin configured to support the boom such that the boom is luffable is provided at the upper portion of the boom as above, the boom support pin can be prevented from becoming an obstacle when an inspector passes through the inspection walkway formed on the side surface of the boom. With this, the labor of an inspection work for the boom conveyor and the like can be reduced. [0023] In the support structure for the tripper coupled to the stacker according to the present invention, a tripper chute may be provided at the tip end portion of the tripper, the tripper chute may be provided inside the upper slewing support portion formed in a 7 circular shape, and the tripper chute may be formed such that a lower opening portion thereof faces a boom conveyor. [0024] In a case where the tripper chute is provided inside the upper slewing support portion formed in a circular shape as above, the upper slewing support portion can support the tip end portion of the tripper. In addition, the tripper chute can be prevented from interfering with the slewing boom, so that the boom can be caused to slew freely. Then, the carried bulks having passed through the tripper and conveyed by a yard conveyor can be caused to pass through the tripper chute to be transferred to the boom conveyor. [0025] A traveling cargo handling device according to the present invention includes: a traveling stacker to which the support structure according to the present invention is applied; and the tripper. [0026] The traveling cargo handling device according to the present invention includes the support structure for the tripper coupled to the stacker according to the present invention, and the support structure for the tripper coupled to the stacker acts in the same manner as above. According to the traveling cargo handling device, the traveling stacker and the tripper coupled to and supported by the traveling stacker can travel on the rails and move to a desired traveling position. At the position to which the traveling stacker and the tripper have moved, the carried bulks conveyed by the yard conveyor can be conveyed obliquely upward by the tripper to be transferred to the boom conveyor. The carried bulks transferred to the boom conveyor can be conveyed by the boom conveyor to be discharged from a tip end portion of the boom conveyor. The discharged carried bulks are stacked on, for example, a yard.

8 Advantageous Effects of Invention [0027] In the support structure for the tripper coupled to the stacker according to the present invention, and the traveling cargo handling device, the tip end portion of the tripper is coupled to and supported by the coupling support portion of the stacker main body, and the counter weight beam can be formed so as to become comparatively long. Therefore, the weight of the counter weight beam including the counter weight for generating a necessary predetermined moment can be reduced. In addition, since the tripper leg portion can be reduced in size, the cost for the traveling stacker and the tripper can be reduced, and a period of time required to manufacture the traveling stacker and the tripper can be reduced.

[Fig. 7] Fig. 7 is a side view showing a conventional traveling cargo handling device. Description of Embodiments [0029] Hereinafter, one embodiment of a support structure for a tripper coupled to a stacker according to the present invention, and a traveling cargo handling device including the support structure will be explained in reference to Figs. 1 to 6. In a traveling cargo handling device 15 shown in Figs. 1A and 1B, as shown in a plan view of Fig. 1B, a boom 17 provided at a traveling stacker 16 has slewed to be located at such a position as to form a substantially right angle with a direction in which rails 18 extend. Fig. 2 shows a tripper 19 coupled to and supported by the traveling stacker 16. A schematic side view of the traveling cargo handling device 15 in Fig. 3 shows a state where the boom 17 of the traveling cargo handling device 15 shown in Fig. 1 is located at such a position as to be parallel to the direction in which the rails 18 extend. [0030] According to the traveling cargo handling device 15 shown in Figs. 1 to 3, the traveling stacker 16 and the tripper 19 coupled to and supported by the traveling stacker 16 can travel on the rails 18, move to a desired traveling position, and stop. At the position to which the traveling stacker 16 and the tripper 19 have moved, the carried bulks conveyed by a yard conveyor 20 can be conveyed obliquely upward by the tripper 19 to be transferred to a boom conveyor 21. The carried bulks transferred to the boom conveyor 21 can be conveyed by the boom conveyor 21 to be discharged from a tip end portion of the boom conveyor 21, that is, a tip end portion of the boom 17. The 10 discharged carried bulks are stacked on, for example, a yard 22. [0031] The traveling stacker 16 included in the traveling cargo handling device 15 shown in Fig. 3 includes: a traveling machine body 23 (a travel bogie, for example) configured to travel on the rails 18 (see Fig. 1) extending along the yard 22; a slewing frame 24 provided on the traveling machine body 23 so as to be slewable; and the boom 17 supported by the slewing frame 24 so as to be luffable. [0032] The boom conveyor 21 is provided at an upper position of the boom 17. A counter weight beam 25 extending in a direction opposite to a direction in which the boom 17 extends is provided at a base end portion of the boom 17. The counter weight beam 25 includes a counter weight 25a. The traveling machine body 23 and the slewing frame 24 are included in a stacker main body 26. [0033] The traveling stacker 16 is provided with: a traveling driving portion for traveling; a slewing driving portion configured to cause the boom 17 to slew; a luffing driving device 27 (a hydraulic cylinder device, for example) configured to cause the boom 17 to luff in an elevating direction; and a conveyor driving portion configured to drive the boom conveyor 21. [0034] The tripper 19 included in the traveling cargo handling device 15 shown in Fig. 3 includes a tripper main body 19a. A tip end portion 19b that is a tip end portion of the tripper main body 19a is coupled to and supported by an upper end portion of the slewing frame 24 of the stacker main body 26 via a coupling support portion 28. The tripper 19 includes a tripper leg portion 29 configured to support the tripper main body 19a. The tripper leg portion 29 includes a wheel at its lower end. The tripper 19 can be towed by the traveling stacker 16 to move on the rails 18. The tripper 19 is hung with the yard conveyor 20 and configured to lift a belt of the yard conveyor 20 obliquely upward.

11 [0035] As shown in Fig. 3, the counter weight beam 25 is arranged so as to pass under the tripper main body 19a by the slewing of the boom 17. [0036] As shown in Fig. 3, the traveling machine body 23 and the tripper leg portion 29 are coupled to each other by a coupling member 41. However, as shown in Fig. 2, the coupling member 41 may be omitted. [0037] A support structure 30 for the tripper coupled to the stacker shown in Fig. 3 is configured such that the tip end portion 19b of the tripper 19 is coupled to and supported by the coupling support portion 28 of the stacker main body 26. Therefore, the tripper leg portion 29 configured to support the tripper 19 and cause the tripper 19 to move on the rails 18 can be provided at a position away from the stacker main body 26 and reduced in size. On this account, the counter weight beam 25 can be prevented from contacting the tripper leg portion 29 when the counter weight beam 25 passes under the tripper main body 19a by the slewing of the boom 17. As a result, the counter weight beam 25 can be formed such that a length L2 (> Li) thereof becomes comparatively large. The counter weight beam 25 includes the counter weight 25a configured to accessorily adjust the balance of the boom 17. [0038] As above, since the counter weight beam 25 can be formed so as to become comparatively long, the weight of the counter weight beam 25 including the counter weight 25a for generating a necessary predetermined moment can be reduced. In addition, since the tripper leg portion 29 can be reduced in size, the cost for the traveling stacker 16 and the tripper 19 can be reduced, and a period of time required to manufacture the traveling stacker 16 and the tripper 19 can be reduced. [0039] As shown in Fig. 3, the tripper leg portion 29 configured to support the tripper main body 19a is provided at a position away from the stacker main body 26. However, since the tip end portion 19b that is the tip end portion of the tripper main body 12 19a is coupled to and supported by the upper end portion of the stacker main body 26 via the coupling support portion 28, the stability of the tripper 19 is excellent. [0040] The slewing frame 24 shown in Fig. 3 is formed to have, for example, a rectangular frame shape and is provided on the traveling machine body 23 via a lower slewing support portion 31 so as to be slewable. The tip end portion 19b of the tripper 19 is provided at an upper portion of the slewing frame 24 via an upper slewing support portion 32. Each of the lower slewing support portion 31 and the upper slewing support portion 32 is constituted by, for example, a slew bearing formed in an annular shape. Instead of this, a different slewing support structure may be adopted. [0041] With this configuration, the weight of the tripper 19 on the stacker main body 26 side in Fig. 3 is supported by the upper slewing support portion 32, the slewing frame 24, the lower slewing support portion 31, and the traveling machine body 23. Since the slewing frame 24 is supported by the lower slewing support portion 31 so as to be slewable, and the tip end portion 19b of the tripper 19 is provided at the upper portion of the slewing frame 24 via the upper slewing support portion 32, the boom 17 provided at the slewing frame 24 can be caused to freely slew together with the slewing frame 24 without being restricted by the traveling machine body 23 at which the lower slewing support portion 31 is provided, and the tripper 19. [0042] As shown in Figs. 4 and 5, the coupling support portion 28 is provided at the upper portion of the slewing frame 24 and has a pin connected structure. The coupling support portion 28 supports the tip end portion 19b of the tripper 19 such that the tip end portion 19b is luffable about a tripper support pin 33 arranged horizontally. [0043] To be specific, two lower pin support portions 34 each configured to support the tripper support pin 33 by a recess formed on an upper surface thereof are provided at the upper slewing support portion 32 shown in Figs. 4 and 5 so as to be spaced apart 13 from each other. Two upper pin support portions 35 each configured such that a recess formed on a lower surface thereof engages with the tripper support pin 33 are provided at a lower surface of the tip end portion 19b of the tripper 19 so as to be spaced apart from each other. The tripper support pin 33 is attached to the recesses formed at a pair of the lower pin support portions 34 and a pair of the upper pin support portions 35. [0044] Although not shown, instead of the above, the tripper support pin 33 may be inserted through through holes formed at a pair of lower projections and a pair of upper projections. [0045] With this configuration, as shown by a chain double-dashed line in Fig. 4, a relative displacement of the tripper main body 19a in a bending direction generated between the tripper 19 and the stacker main body 26 when the tripper main body 19a bends by, for example, the weights of the tripper main body 19a and the carried bulks on the tripper 19 is acceptable by the coupling support portion 28 (pin connected structure). Thus, a force, such as a moment acting on the stacker main body 26, acting on the tripper main body 19a and the stacker main body 26 based on the above relative displacement can be reduced or eliminated. [0046] Further, with this, an offset load acting on the upper slewing support portion 32 (slew bearing) and the lower slewing support portion 31 (slew bearing) shown in Fig. 4 can be reduced or eliminated. Therefore, the slewing support portions 31 and 32 can be reduced in size, and the lives thereof can be extended. [0047] As shown in Figs. 4 and 5, the boom 17 is provided so as to be inserted through the slewing frame 24, and an upper portion of the boom 17 is suspended from an upper frame of the slewing frame 24 via a boom support pin 36 so as to be luffable. The boom 17 can luff about the boom support pin 36 in the elevating direction. [0048] To be specific, two lower pin support portions 37 each including a pin hole 14 through which the boom support pin 36 is inserted are provided so as to respectively project upward from left and right side surfaces of the boom 17 shown in Fig. 5. Two upper pin support portions 38 projecting downward from a lower surface of the upper frame of the slewing frame 24 are provided so as to be spaced apart from each other. The boom support pin 36 is inserted through through holes formed at a pair of lower projections 37 and a pair of upper projections 38. [0049] With this configuration, when the boom 17 shown in Fig. 4 is caused to luff about the boom support pin 36 in the elevating direction, the center of this luffing operation can be caused to be located at the upper portion of the boom 17. [0050] With this, in a case where a center of gravity (a center of gravity of the boom 17 and the like) G1 of the total of the weights of the boom 17, the boom conveyor 21, and the carried bulks conveyed by the boom conveyor 21 is located at the upper portion of the boom 17, a center position of the luffing operation of the boom 17 can be caused to get close to the position of the center of gravity of the boom 17 and the like. [0051] As a result, as shown in a diagram on the left side of Fig. 6, movement distances S1 and S2 of the position of the center of gravity G1 of the boom 17 and the like in the horizontal direction when the boom 17 is caused to luff can be reduced, and a force, such as a moment, acting on the stacker main body 26 by the weights of the boom 17 and the like by the movement of the position of the center of gravity of the boom 17 and the like in the horizontal direction can be reduced. [0052] With this, a force generated by a luffing driving device 27 (see Fig. 1A), such as a hydraulic cylinder device, configured to, for example, cause the boom 17 to luff in the elevating direction can be made low, and the cost can be reduced, for example, the hydraulic cylinder device can be reduced in size. [0053] In the present embodiment, as shown in the diagram on the left side in Fig.

15 6, the center of gravity G1 is located above the boom 17. Because of the weight of the counter weight 25a, the center of gravity G1 is located above the boom 17. [0054] Fig. 6 shows a relation between the boom support pin 36 and the position of the center of gravity G1 of the boom 17 and the like. The diagram on the left side in Fig. 6 shows an example of the present embodiment, and the boom support pin 36 is provided at a position above the boom 17. A diagram on the right side in Fig. 6 shows an example in which the boom support pin 36 is provided at a substantially center position of the boom 17. As is clear from Fig. 6, in a case where a distance K2 between the boom support pin 36 and the center of gravity G1 is reduced to a distance K1 (K2 K1 = K3), the movement distances S3 and S4 of the center of gravity G1 in the horizontal direction when the boom 17 is caused to luff can be respectively reduced to the distances S1 and S2. [0055] As shown in Fig. 5, the boom 17 is provided so as to be inserted through the slewing frame 24, and the upper portion of the boom 17 is suspended from the slewing frame 24 via the boom support pin 36 so as to be luffable. In addition, inspection walkways 39 are respectively formed on left and right side surfaces of the boom 17. [0056] In a case where the boom support pin 36 configured to support the boom 17 such that the boom 17 is luffable is provided at the upper portion of the boom 17 as above, the boom support pin 36 can be prevented from becoming an obstacle when an inspector passes through the inspection walkways 39 respectively formed on the left and right side surfaces of the boom 17. With this, the labor of an inspection work for the boom conveyor 21 and the like can be reduced. [0057] As shown in Fig. 5, since the boom support pin 36 and the boom conveyor 21 are respectively provided at positions located at the upper portion of the boom 17 and close to each other, the inspector can easily inspect both the boom support pin 36 and the 16 boom conveyor 21 from the inspection walkways 39. [0058] Further, as shown in Figs. 4 and 5, the tip end portion 19b of the tripper 19 is provided with a tripper chute 40. The tripper chute 40 is provided inside the upper slewing support portion 32 formed in a circular shape and is formed such that a lower opening portion thereof faces an upper surface of the boom conveyor 21. [0059] In a case where the tripper chute 40 is provided inside the upper slewing support portion 32 formed in a circular shape as above, the upper slewing support portion 32 can support the tip end portion 19b of the tripper 19. In addition, the tripper chute 40 can be prevented from interfering with the slewing boom 17, so that the boom 17 can be caused to slew freely. Then, the carried bulks having passed through the tripper 19 and conveyed by the yard conveyor 20 can be caused to pass through the tripper chute 40 to be transferred to the boom conveyor 21. [0060] As shown in Fig. 3, the above embodiment has explained an example in which the traveling machine body 23 configured to travel is provided at the traveling stacker 16, not at the tripper 19. However, instead of this, the traveling machine bodies each configured to travel may be respectively provided at the traveling stacker 16 and the tripper 19. [0061] In the above embodiment, the boom 17 is configured to be luffable. Instead of this, the boom 17 is configured to be not luffable. Industrial Applicability [0062] As above, the support structure for the tripper coupled to the stacker according to the present invention, and the traveling cargo handling device have an excellent effect in which the counter weight beam can be formed so as to be comparatively long, and this can reduce the weight of the counter weight beam, and 17 therefore, the weights of the traveling stacker and the tripper. The present invention is suitably applied to the support structure for the tripper coupled to the stacker, and the traveling cargo handling device.
