[0001] The present invention relates to a suspended belt conveyor supported by a cable stretched along the conveying direction. [Background technology]

[0002] As this type of belt conveyor, for example, the technology described in Patent Document 1 is known. The belt conveyor described in the document has at least a pair of support columns, and the conveyor frame is supported in the conveying direction by two upper cables and two lower cables that are stretched between the pair of support columns in a catenary curve. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] EP1958896B1(FIG5) Summary of the Invention [Problem to be solved by the invention]

[0004] However, the support system that holds the conveyor frame with these four cables requires a large tension to reduce the inclination angle of the support column, so the support column and tensioner must be highly rigid, and the entire conveyor equipment becomes large-scale. Therefore, the present invention has been made with a focus on such problems, and an object of the present invention is to provide a suspended type belt conveyor that can reduce the tension of the main cable as much as possible and simplify the overall conveyor equipment. [Means for solving the problem]

[0005] In order to solve the above problems, a belt conveyor according to one embodiment of the present invention is a belt conveyor supported by a plurality of cables stretched along a load transport direction, and is characterized in comprising at least two main towers, a pair of main cables stretched between the two main towers at a distance from each other in a width direction perpendicular to the transport direction so as to draw a catenary curve, a plurality of pairs of hanger wires hanging down from each of the pair of main cables at opposing positions in the width direction, a conveyor body supported along the transport direction by the plurality of pairs of hanger wires, and an endless conveyor belt that is hung around a plurality of rollers of the conveyor body in the transport direction so as to be able to circulate infinitely.

[0006] According to the belt conveyor of the present invention, the conveyor body is supported in the conveying direction by multiple pairs of hanger wires hanging down from a pair of main cables. Therefore, even if the conveying path of the conveyor body is arranged horizontally, the tension of the pair of main cables can be made as small as possible, and the entire conveyor equipment can be configured simply.

[0007] Here, in a belt conveyor according to one embodiment of the present invention, it is preferable that the conveyor body comprises a plurality of cross beams supported horizontally along the width direction by each pair of the plurality of pairs of hanger wires, a pair of vertical beams respectively suspended between both side portions of the plurality of cross beams, a carrier roller set provided at opposing positions in the width direction between the pair of vertical beams and constituting the forward path of the plurality of rollers, and a return roller set provided on the cross beams and constituting the return path of the plurality of rollers. In addition, in the belt conveyor according to one aspect of the present invention, it is preferable that at least one adjacent one of the plurality of cross beams has an insulating structure that does not have a solid connection between them.

[0008] With this configuration, a cross beam is supported horizontally along the width direction for each pair of multiple pairs of hanger wires hanging from a pair of main cables, multiple return roller sets are provided on the multiple cross beams, a pair of vertical beams are hung between both sides of each of the multiple cross beams, and carrier roller sets are provided in opposing positions in the width direction between the pair of vertical beams, which is advantageous in simplifying the entire conveyor equipment while minimizing the tension in the pair of main cables as much as possible.

[0009] In the belt conveyor according to any one of the aspects of the present invention, the conveyor belt is arranged so that a conveying path of the conveyor belt is substantially horizontal. versus It is preferable that the lengths of the hanger wires are set in order. In addition, in the belt conveyor according to any one of the aspects of the present invention, it is preferable that the belt conveyor has a walkway that is arranged along the conveying direction, extends laterally in the width direction beyond the plurality of roller brackets, and allows workers to walk on the walkway.

[0010] In addition, in order to solve the above-mentioned problems, a belt conveyor according to another embodiment of the present invention is a belt conveyor supported by a plurality of cables stretched along a transport direction of a load, and is characterized in comprising at least two main towers, a pair of main cables stretched between the two main towers at a distance in a width direction perpendicular to the transport direction and drawn a catenary curve, a plurality of pairs of hanger wires hanging down from each of the pair of main cables at opposing positions in the width direction, a conveyor body supported along the transport direction between pairs of main cables facing each other in the width direction by the plurality of pairs of hanger wires, and a walkway arranged along the conveyor body, extending laterally in the width direction beyond the conveyor body, and on which workers can walk.

[0011] According to a belt conveyor according to another aspect of the present invention, the conveyor body is supported along the conveying direction by a plurality of pairs of hanger wires hanging down from a pair of main cables. Therefore, even if the conveyor body is arranged horizontally along the conveying path, it is possible to minimize the tension of the pair of main cables, and the entire conveyor equipment can be constructed simply. In addition, a walkway that protrudes laterally in the width direction from the conveyor body and on which workers can walk is arranged along the conveyor body, so that the entire conveyor equipment is constructed simply and has excellent maintainability. Effect of the Invention

[0012] As described above, according to the present invention, the tension in the main cable is reduced, and the overall conveyor facility can be constructed simply. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that the drawings are schematic. Therefore, it should be noted that the relationship and ratio between thickness and planar dimensions are different from the actual ones, and the drawings include parts where the relationship and ratio of dimensions are different from each other. Furthermore, the embodiments described below are merely examples of devices and methods for embodying the technical ideas of the present invention, and the technical ideas of the present invention do not limit the materials, shapes, structures, arrangements, etc. of the components to the embodiments described below.

[0015] As shown in Fig. 1, the belt conveyor 100 of this embodiment is a suspension type belt conveyor, and includes a pair of main cables 20 stretched along the direction of conveying the load, and multiple pairs of hanger wires 30 suspended at positions facing each other in the width direction from each of the pair of main cables 20. A conveyor body 40 of the belt conveyor 100 is supported along the conveying direction by the multiple pairs of hanger wires 30 in the middle of the conveying path.

[0016] The conveyor body 40 has a cylindrical header roller 41 arranged at the leading end of the conveying path, and a cylindrical footer roller 42 arranged at the trailing end. The conveyor belt 90 is wound around the header roller 41 and the footer roller 42 so as to be able to circulate endlessly along the conveying path. The conveyor belt 90 is wound around the conveyor body 40 in a flat, spread state near the header roller 41 and the footer roller 42.

[0017] A drive unit 43 is attached to the vicinity of the header roller 41. A hopper 44 is provided on the side of the header roller 41 so that loads such as excavated soil and sand can be dropped. A loading device 45 is disposed on the footer roller 42 side, which loads such as excavated soil and sand onto the conveyor belt 90. Also disposed on the footer roller 42 side are a tensioning mechanism for the conveyor belt 90, a counterweight, a cleaning device, and other equipment (not shown) that are provided below.

[0018] The belt conveyor 100 of this embodiment includes a plurality of main towers 10. Each main tower 10 is constructed of steel or reinforced concrete on a foundation at a distance in the width direction. When the foundation is underwater, the main towers 10 can be constructed by submerging a caisson in water and pouring concrete into it. Anchors 11 are constructed at both ends of the main towers 10 located at both ends. The anchors 11 are concrete blocks constructed at both ends of the suspended belt conveyor 100, and function as anchors for anchoring the main cable 20. When there are topographical constraints or solid bedrock, the bearing force of the ground can also be utilized.

[0019] In the belt conveyor 100 of this embodiment, as shown in an enlarged view in Fig. 2, a main cable 20 is stretched between at least two adjacent main towers. As shown in a perspective view in Fig. 3, the main cable 20 is composed of a pair of main cables 20L, 20R that are spaced apart in the width direction perpendicular to the conveying direction and form a catenary curve. Hereinafter, when there is no particular need to distinguish between the pair of main cables 20L, 20R, they will also be simply referred to as "main cables 20". A plurality of steel wires (piano wires) bundled in parallel is usually used as the main cable 20. The main cable 20 may be surface-treated with rubber or paint to prevent corrosion (rust).

[0020] In this embodiment, a pair of main cables 20L, 20R are stretched between each main tower 10 and the anchor 11, and between a pair of adjacent main towers 10, as shown in Fig. 1. The main cable 20 is stretched over the top saddle 10s of each main tower 10, and suspends the conveyor body 40 through the hanger wire 30 along the conveying direction. Pairs of hanger wires 30L, 30R hang down from appropriate positions of the pair of main cables 20L, 20R at positions facing each other in the width direction. As with the "main cable 20," hereinafter, when there is no need to distinguish between the pairs of hanger wires 30L, 30R, they will also be referred to simply as "hanger wires 30."

[0021] In this embodiment, the hanger wire 30 is set to different lengths depending on the position in the conveying direction in order to connect the main cable 20, which forms a catenary line, to the roller brackets 60 so that the arrangement posture of the multiple roller brackets 60 is approximately horizontal, as shown in Figure 2. A twisted wire is used for the hanger wire 30. The multiple hanger wires 30 hang down from the main cable 20 to substantially horizontally support the conveyor body 40. The hanger wires 30 hang down from the main cable 20 at predetermined intervals.

[0022] In this embodiment, as shown in FIG. 3, the upper ends of each hanger wire 30L, 30R are connected to the corresponding main cables 20L, 20R by cable bands 33, and the hanger wires 30L and 30R hang down at a predetermined interval from the pair of main cables 20L, 20R, respectively. In this embodiment, as shown in Fig. 3 and Fig. 4, the lower end 32 of the hanger wire 30 is fixed to the upper surface of the cross beam 50. A return roller set 62 that constitutes the return path among the multiple guide rollers is provided on the upper surface of the cross beam 50. A pair of vertical beams 72 is hung between both side portions of the multiple cross beams 50.

[0023] Of the pair of vertical beams 72, roller brackets 60 are provided at positions facing each other in the width direction between the inner vertical beams 72, and a carrier roller set 61 is supported by each roller bracket 60. The carrier roller set 61 constitutes the outgoing path of the multiple guide rollers. More specifically, as shown in Fig. 3, the conveyor body 40 of this embodiment has a plurality of upper carrier roller sets 61 and a plurality of lower return roller sets 62 as guide rollers in the middle of the conveying path. Each of the carrier roller sets 61 and the return roller sets 62 is configured with a plurality of cylindrical guide rollers, and both ends of each guide roller are supported so as to be rotatable about its own axis.

[0024] In this embodiment, the upper carrier roller set 61 is provided on a gate-shaped roller bracket 60. In this embodiment, the carrier roller set 61 is mounted on the roller bracket 60, and each roller bracket 60 is formed into a gate shape using thin rectangular column members so as to be less susceptible to the effects of wind. The lower ends of the left and right support columns 60h of the roller bracket 60 are fixed to the inner surfaces of the pair of inner vertical beams 72, respectively. The upper carrier roller set 61 is supported in a U-shaped form upward by a roller support wire 61w connected to a roller bracket 60. For example, five guide rollers (carrier rollers) are connected in a bead-like manner to hold each guide roller rotatably about its axis. In this embodiment, both ends of the roller support wire 61w are fixed to the fixing portion 61j of the roller bracket 60, thereby supporting a plurality of guide rollers so as to be freely rotatable.

[0025] Also, the lower return roller set 62 supports, for example, two guide rollers (return rollers) in a V-shaped form that is nearly flat by a support bracket 62b, while holding each guide roller rotatably about its axis. Accordingly, in this embodiment, each of the plurality of upper carrier roller sets 61 provided on the roller bracket 60 conveys the conveyor belt 90 in a semi-circular arc-shaped support state with a substantially U-shaped cross-section that opens upward in the forward path, and in the return path, the conveyor belt 90 is conveyed in a substantially flat state by the plurality of lower return roller sets 62.

[0026] Here, in this embodiment, as shown in FIG. 4, the forward path guide pitch Pc in the forward path by the carrier roller sets 61 adjacent in the conveying direction and the return path guide pitch Pr in the return path by the return roller sets 62 adjacent in the conveying direction are configured such that the forward path guide pitch Pc is smaller than the return path guide pitch Pr (Pc < Pr). In the example of this embodiment, the forward path guide pitch Pc is set to 1 / 2 of the return path guide pitch Pr (that is, 2 × Pc = Pr). Thereby, the belt conveyor 100 of this embodiment increases the number of carrier roller sets 61 arranged in the forward path that receives a large load of the load, and minimizes the number of return roller sets 62 arranged in the return path that does not receive the load of the load, while maintaining a stable conveying ability and simplifying the entire conveyor facility.

[0027] In this embodiment, as shown in Fig. 3, the conveyor body 40 of the belt conveyor 100 has an insulation structure DS in which at least one adjacent cross beam 50 is not connected by a vertical beam 72, and thus does not have a firm connection between the cross beams. Note that the figure shows one insulation unit in which the front and rear of one vertical beam 72 are separated from the other vertical beam 72 adjacent to it in the conveying direction. The floor plate 70 and the vertical beam 72 may have a split structure or a joint structure at an appropriate location in the conveying direction. This split structure or joint structure may be provided at the cross beam 50 or between adjacent cross beams 50. It is preferable to arrange the split structure parts of the floor plate 70 and the vertical beam 72 at the location where the insulation structure DS is provided. In particular, in this embodiment, the split structure parts of the floor plate 70 and the vertical beam 72 are arranged at the cross beam 50.

[0028] Furthermore, in this embodiment, in order to allow workers to walk on the conveyor body 40 of the belt conveyor 100, a floor plate 70 made of punching metal or the like is placed and fixed on the upper surfaces of two adjacent vertical beams 72 on the side, and a walkway serving as a work passage W is provided. The walkway serving as the work passage W is arranged along the conveying direction and protrudes laterally in the width direction beyond the left and right supports 60h of the multiple roller brackets 60.

[0029] Furthermore, in this embodiment, at least one of the locations of the belt conveyor 100 in the middle of the conveying path of the conveyor body 40 is provided with an anti-sway wire 80, one end of which is connected and the other end of which is hung down and fixed to the ground. In this embodiment, two anti-sway wires 80L, 80R are provided on the lower surfaces of all the cross beams 50 of the conveyor body 40, spaced apart in the width direction. When the two anti-sway wires 80L, 80R are not particularly distinguished from each other, they are also simply referred to as "anti-sway wires 80". The upper end 83 of each anti-sway wire 80 is fixed to the underside of the cross beam 50, and the anchor 82 at the lower end of the anti-sway wire 80 is embedded in the ground surface and firmly fixed. In this embodiment, the anti-sway wires 80 are provided on the underside of all the cross beams 50 in the same configuration.

[0030] Next, the operation and effects of the belt conveyor 100 of this embodiment will be described. In the belt conveyor 100 of this embodiment, when the header roller 41 is driven by the driving device 43, the conveyor belt 90 starts infinite circulation between the leading header roller 41 and the trailing footer roller 42. The conveyor belt 90 is wound in a flat and spread state near the cylindrical header roller 41 and the cylindrical footer roller 42. In the middle of the conveying path, in the upper outward path, the conveyor belt 90 is conveyed in a state in which it is supported in a semicircular arc shape with a cross section opening upwardly in a substantially U-shape by a plurality of carrier roller sets 61 of a roller bracket 60. Furthermore, in the lower return path, the conveyor belt 90 is conveyed in a substantially flat state by a plurality of return roller sets 62.

[0031] As a result, according to the belt conveyor 100 of this embodiment, the endless conveyor belt 90 is rotated in a substantially U-shaped support state on the outward path. This prevents the load from spilling during transportation. In addition, since the conveyor belt 90 is transported in a substantially flat state on the outward path, the height of the conveyor body 40 can be made compact. This is preferable for simplifying the entire conveyor equipment. Although not shown in the above embodiment, it is preferable to cover the upper part of the roller bracket 60 with a roof or cover.

[0032] Here, for example, in the suspended belt conveyor described in Patent Document 1, the conveyor frame is supported by four cables that form a catenary curve between a pair of supports, so a large tension is required to reduce the inclination angle of the supports. Therefore, the supports and tensioners are required to have high rigidity, and the entire conveyor equipment becomes large-scale.

[0033] In contrast, the belt conveyor 100 of this embodiment, as described above, is configured to include a pair of main cables 20L, 20R that are suspended at a distance in the width direction perpendicular to the conveying direction between at least two adjacent main towers 10 and tensioned to form a catenary curve, multiple pairs of hanger wires 30 that hang down from each of the pair of main cables 20L, 20R at opposite positions in the width direction, a conveyor body 40 that is supported along the conveying direction by the multiple pairs of hanger wires 30, and an endless conveyor belt 90 that is wrapped around multiple guide rollers of the conveyor body 40 in the conveying direction so as to be able to circulate infinitely.

[0034] In other words, the suspended belt conveyor described in Patent Document 1 is a so-called "catenary conveyor", whereas the suspended belt conveyor 100 of the present embodiment is a so-called "suspension conveyor". As a result, according to the belt conveyor 100 of this embodiment, the conveyor body 40 is supported along the conveying direction by a plurality of pairs of hanger wires 30 suspended from a pair of main cables 20L, 20R. Therefore, even if the conveying path of the conveyor body 40 is arranged to be horizontal, it is possible to reduce the tension of the pair of main cables 20L, 20R as much as possible, and the entire conveyor equipment constituting the belt conveyor 100 can be simply configured.

[0035] In particular, according to the belt conveyor 100 of this embodiment, the conveyor body 40 has an insulating structure DS that does not have a rigid connection between at least one adjacent location among the multiple cross beams 50, so that even if the conveying path by the conveyor body 40 is arranged horizontally, the tension of the pair of main cables 20L, 20R can be made as small as possible, which is preferable for simplifying the entire conveyor equipment. Furthermore, according to the belt conveyor 100 of this embodiment, the conveyor body 40 is arranged along the conveying direction, extends laterally in the width direction beyond the conveyor belt 90, and has a work passage W that serves as a walkway along which workers can walk, so that the entire conveyor equipment is simply constructed and has excellent maintainability.

[0036] In addition, according to the belt conveyor 100 of this embodiment, the conveyor body 40 has a vibration prevention wire 80, one end of which is connected to at least one location in the middle of the conveying path and the other end of which is hung down to the ground and fixed, thereby significantly reducing lateral vibration of the conveyor body 40. In other words, while a suspended conveyor has the drawback of being easily swayed by wind or weight, the anti-sway wire 80 pulls the conveyor body 40 downward, and the main cable 20 and the hanger wire 30 pull the conveyor body 40 upward, so that the conveyor body 40 does not easily move even if it is exposed to wind from the side, and the lateral swaying of the belt conveyor 100 can be significantly reduced.

[0037] As described above, according to the belt conveyor 100 of this embodiment, even if the conveying path of the conveyor body 40 is arranged horizontally, the tension in the pair of main cables 20L, 20R can be made as small as possible, while the entire conveyor equipment can be configured simply. The belt conveyor according to the present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0038] For example, in the above embodiment, a configuration example in which the cross beam 50 is supported by the hanger wire 30 has been shown, but the present invention is not limited to this. For example, a configuration in which the carrier roller set 61 and the return roller set 62 are directly supported by the hanger wire 30 without providing the cross beam 50 may be adopted. Even with this configuration, even if the conveying path of the conveyor body 40 is arranged horizontally, the tension in the pair of main cables 20 can be made as small as possible, and the entire conveyor facility can be simply configured.
