Description

[Technical Field]

[0001] The present invention relates to a rack for an ore transport route and an ore transport facility. More specifically, the present invention relates to a rack for an ore transport route that supports a transport route for transporting ore or the like at a predetermined height from the ground, and to an ore transport facility in which the ore transport route is placed on the rack. [Background technology]

[0002] A stacker device (see Figure 1) used to continuously stack bulk materials such as ore and coal in a storage yard can stack loads higher if it runs as far away as possible from the ground surface (G in Figure 1).Therefore, the "ore conveying path (i.e., the running rails on which the stacker device itself runs)" is installed on a "frame for the ore conveying path" that supports it at a specified height above the ground (see Patent Document 1).

[0003] As described above, the "ore transport route frame" that supports the ore transport route at an elevated position a predetermined distance above the ground is composed of a beam that extends in the direction in which the ore transport route extends and a plurality of supports that support the beam from below. Generally, in bridge structures that support the travel paths of various heavy vehicles and heavy machinery, the beams that span between the supports are made of steel materials with horizontally protruding flanges, such as H-shaped steel, in order to maintain the required strength (see Patent Document 2). The same applies to the "ore transport route frame" that supports the running rails of a stacker device, and in the "ore transport route frame," the beams that support heavy structures are generally made of steel materials with horizontally protruding flanges, such as H-shaped steel.

[0004] In this way, the "ore transport route frame" ensures the necessary strength by using steel materials with horizontally protruding flanges as the beam components. However, a problem with this type of structure is that ore spilling from the ore transport route above tends to accumulate on the top surface of the horizontally protruding flanges. If this accumulation is left unchecked, there is a risk that the accumulated deposits will fall downward and hit people or equipment. To prevent such accidents, it has been necessary to periodically perform high-altitude work to remove the ore accumulated on the top surface of the flanges. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 63-306127 [Patent Document 2] Utility Model Registration No. 3218787 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to prevent ore that has spilled from an ore transport route from accumulating on the upper surface of the beams that make up the ore transport route's frame, thereby reducing or eliminating the workload involved in removing this deposit and preventing accidents caused by the falling of the deposit. [Means for solving the problem]

[0007] The inventors have found that the above-mentioned problems can be solved by providing a structure in which the ore transport path frame has an inclined surface that covers the upper surface of the flange, and have completed the present invention. Specifically, the present invention provides the following.

[0008] (1) A platform for an ore transport route, which is composed of a beam that supports the ore transport route and a plurality of pillars that support the beam at a predetermined height, wherein the beam is made of steel having at least a web arranged along the vertical direction and a lower flange that extends horizontally from the lower end of the web, and an inclined surface is formed that covers the upper surface of the lower flange and extends diagonally downward from the side of the web to reach the upper surface or outer end of the lower flange.

[0009] (1) The ore transport route stand prevents ore that falls from the ore transport route from accumulating on the upper surface of the beams that make up the ore transport route stand, thereby reducing or eliminating the workload for removing this deposit and preventing accidents caused by the falling of the deposit.

[0010] (2) A rack for an ore transport path according to (1), wherein the inclination angle of the inclined surface is equal to or greater than the angle of repose of the ore being transported on the ore transport path.

[0011] According to the ore transport route stand of (2), by optimizing the inclination angle of the inclined surface in accordance with the properties of the ore actually being transported in the ore transport route stand described in (1), it is possible to more reliably prevent ore that has spilled from the ore transport route from accumulating on the upper surface of the beams that constitute the ore transport route stand.

[0012] (3) The ore transport path rack according to (1), wherein the inclination angle of the inclined surface is 55° or more.

[0013] According to the ore transport route stand of (3), in the ore transport route stand described in (1), the inclination angle of the inclined surface is made large enough to be effective for the various types of ores handled in mining and industrial facilities. In an ore transport route that carries various ores, ore that falls off the ore transport route can be made to quickly slide off the top surface of the beam, preventing the ore from accumulating on the top surface of the beam.

[0014] (4) A rack for an ore transport path according to any one of (1) to (3), wherein the lower side end of the inclined surface reaches the outer side end of the lower flange.

[0015] According to the ore transport route stand of (4), the horizontal surface portion on the lower flange, which was prone to accumulation of fallen objects due to its structure, does not exist, so that the above-mentioned effects of the ore transport route stand described in any of (1) to (3) can be more reliably enjoyed.

[0016] (5) A rack for an ore transport path according to any one of (1) to (4), wherein the inclined surface is formed by an inclined surface forming member having a cross-sectional shape of a substantially right-angled triangle.

[0017] According to the ore transport route frame of (5), by additionally installing a member for forming an inclined surface having a simple three-dimensional shape on an existing frame, the ore transport route frame described in any one of (1) to (4) can be obtained. As a result, even in existing ore transport facilities, the above-mentioned effects provided by the ore transport route frame described in any one of (1) to (4) can be enjoyed by simply adding parts.

[0018] (6) The inclined surface forming member has a corner portion facing the inclined surface, which is formed by cutting out a groove along the longitudinal direction of the inclined surface forming member, in the ore transport path frame described in (5).

[0019] According to the ore transport route rack of (6), even if the corners where the flanges and webs of the H-shaped steel beams intersect have rounded corners or protrusions such as welded buildups, the bottom and vertical surfaces of the inclined surface forming members can be tightly attached to the surface of the beams without any gaps. This makes it possible to maintain the stability of the joint between the inclined surface forming members and the beams and the aesthetic appearance of the joints in a desirable state, even when the above-mentioned rounded corners or protrusions are present.

[0020] (7) The ore transport path stand according to (5) or (6), wherein the inclined surface forming member has fixing magnets embedded in a surface other than the surface that constitutes the inclined surface.

[0021] According to the ore transport route rack of (7), it is possible to easily install the inclined surface forming members on the steel material constituting the beam. Furthermore, it is also easy to replace the inclined surface forming members as needed, including replacing them with other members having different inclination angles.

[0022] (8) An ore transport facility, comprising a frame for an ore transport path according to any one of (1) to (7), and an ore transport path for transporting ore placed on the upper surface side of the beam.

[0023] According to the ore transport equipment of (8), the above-mentioned effects of the ore transport route stand described in any one of (1) to (7) can be enjoyed, and maintenance costs can be reduced while maintaining safety around the installation site during operation of the ore transport equipment.

[0024] (9) The ore conveying facility according to (8), wherein the ore conveying path is a belt conveyor.

[0025] According to the ore conveying equipment of (9), the above-mentioned effects of the ore conveying route stand described in (8) can be enjoyed, and maintenance costs can be reduced while maintaining safety around the installation site during operation of the ore conveying equipment equipped with a belt conveyor.

[0026] (10) The ore transport facility according to (8), wherein the ore transport path is a running rail of a stacker device.

[0027] According to the ore conveying equipment of (10), the above-mentioned effects of the ore conveying route stand described in (8) can be enjoyed, and maintenance costs can be reduced while maintaining safety around the installation location during operation of the ore conveying equipment equipped with a stacker device. [Effects of the Invention]

[0028] The present invention prevents ore that has spilled from the ore transport route from accumulating on the upper surface of the beams that make up the ore transport route's frame, thereby reducing or eliminating the workload involved in removing the deposits and preventing accidents caused by the deposits falling.

DETAILED DESCRIPTION OF THE INVENTION

[0030] Hereinafter, preferred embodiments of the "ore transport route platform" of the present invention and the "ore transport facility" that can be configured using the same will be described. However, the present invention is not limited to the following embodiments.

[0031] <Ore transport route platform> The "ore transport route frame" (hereinafter simply referred to as "frame") of the present invention is configured to include a beam that supports the ore transport route from below, and a plurality of supports that support the beam from below at a plurality of locations at a predetermined height. Figure 1 is a diagram that schematically shows an example of a preferred embodiment of the present invention, a frame 10 for an ore transport route, and the overall configuration of an ore transport facility 100 configured using the frame 10.

[0032] In this specification, the term "ore transport path" refers to the equipment itself, such as a "belt conveyor," on which ore or other transported materials are directly placed and transported. However, this is not limited to this, and structures such as the above-mentioned "stacker device running rails" and other running rails for moving heavy machinery that handles ore or other materials in a predetermined direction are also included as examples of "ore transport path" in this specification.

[0033] In the platform 10, the beam 1, which supports the ore transport path (running rails of the stacker device) 3 from below, is supported at multiple locations by multiple support columns 2 having a predetermined height. The support columns 2 may be any structure that can stably hold the beam 1, the ore transport path 3 placed above it, and other components of the ore transport equipment 100 at a predetermined height. Furthermore, it is preferable that the support columns 2 are of a height that ensures sufficient space for heavy machinery and workers to pass freely under the beam. The platform 10 having the above basic configuration is mainly characterized in that an inclined surface 141 is formed on the upper surface of the lower flange 11 of the steel material that constitutes the beam 1, as shown in FIG. 2.

[0034] As an example, the beam 1 constituting the frame 10 can be formed of an H-shaped steel having a lower flange 11, a web 12, and an upper flange 13, as shown in FIGS. 2 and 3 . The steel material constituting the beam 1 may be one in which the web 12 and the flanges 11 and 13 are joined by welding or the like, or may be integrally formed. Furthermore, the beam constituting the "frame" of the present invention is not limited to an H-shaped steel, and may be any steel material having at least a lower flange extending horizontally from the lower end of a web that can be arranged vertically, or a shape equivalent to this. Specifically, the beam of the "frame" of the present invention can be formed using various types of shaped steel, such as an H-shaped steel, an I-shaped steel, a channel steel, or an angle steel.

[0035] The inclined surface 141, which is a characteristic structure of the frame 10, is an inclined surface that is installed to cover a part, preferably the entirety, of the upper surface of the lower flange 11 of the beam 1. Moreover, this inclined surface 141 is a downward inclined surface that extends diagonally downward from the side surface of the web 12 to reach the upper surface of the lower flange 11. Note that, as shown in Figures 2 and 3, it is preferable that the lower side end of the inclined surface 141 reaches the outer side end of the upper surface of the lower flange 11 and is joined to this part, so that the entire upper surface of the lower flange 11 is covered by the inclined surface 141. Note that the above-mentioned "side surface of the web 12" refers to a vertical surface that extends along the traveling direction of the ore transport path among the surfaces of the web 12, including the side, front, and back surfaces.

[0036] In the frame 10, the inclined surface 141 can be installed anywhere on the upper surface of the lower flange 11 of the steel material forming the beam 1, as needed. However, when considering the overall configuration of the ore conveying equipment configured using the frame of the present invention, it is preferable to preferentially install this inclined surface in a portion where ore that has spilled from the ore conveying path (for example, the running rail of a stacker device) or the like is particularly likely to accumulate. As an example, in the case of a frame in which multiple beams are arranged in parallel, it is preferable to preferentially install the inclined surface on the upper surface of the lower flange of a pair of beams that are arranged at each outer end in a direction perpendicular to the traveling direction of the ore conveying path (the width direction of the beams), and in a portion that protrudes from the web toward the outside in the width direction of the conveying path.

[0037] The inclination angle of the inclined surface 141, i.e., the angle formed by the upper surface of the outward protruding portion of the lower flange 11 and the inclined surface 141, is preferably set to an angle equal to or greater than the angle of repose of the ore, etc., which is the material to be transported on the ore transport path installed on the platform. Here, the angle of repose of the ore, coal, etc., handled in a typical mining and industrial site varies depending on the variation in particle size and conditions such as humidity, but is generally within the range of 35° to 55°. For example, by setting the inclination angle of the inclined surface 141 to 55° or greater, it is possible to prevent ore spilling from the ore transport path 3 from accumulating on the upper surface of the beams 1 constituting the platform 10 of the ore transport path, even for various types of ores handled in a typical mining and industrial facility. Furthermore, by configuring the inclination angle to be 55° or more, preferably 60°, and by configuring the entire upper surface of the lower flange 11 to be covered by the inclined surface 141 as described above, it is possible to more reliably prevent ore and the like that has spilled from the ore transport path 3 from accumulating on the upper surface of the beam 1 that constitutes the frame 10.

[0038] [Inclined surface forming member] 2 to 5, the inclined surface 141, which is a characteristic structure of the gantry 10, can be formed using an inclined surface forming member 14 in the shape of a triangular prism whose cross section is a substantially right-angled triangle. The inclined surface forming member 14 is a substantially triangular prism-shaped member having two bottom surfaces each having a substantially right-angled triangle shape, and having three side surfaces: an inclined surface 141 (a surface that constitutes the inclined surface 141 in the gantry 10), and two other surfaces other than the inclined surface 141 that are perpendicular to each other, a vertical surface 142 and a horizontal surface 143. The material of the inclined surface forming member 14 is not particularly limited as long as it is durable and weather-resistant in accordance with the environment where the gantry 10 is installed. However, resin or rubber is preferable because it is lightweight, inexpensive, and easy to process.

[0039] 2, the inclined surface 141, which is a characteristic structure of the frame 10, can be formed by joining and fixing the inclined surface forming member 14, which has a substantially triangular prism shape, with the horizontal surface 143 abutting against the upper surface of the lower flange 11 of the beam 1 and the vertical surface 142 abutting against the side surface of the web 12. Note that the angle formed by the horizontal surface 143 abutting against the upper surface of the lower flange 11 of the beam 1 and the inclined surface 141 of the inclined surface forming member 14 is preferably equal to or greater than the angle of repose of the ore or the like that is the transported object of the above-mentioned ore transport path, or an angle of 55° or greater.

[0040] 4, the inclined surface forming member 14 can have recessed portions 144 formed by cutting out grooves along the longitudinal direction of the inclined surface forming member 14 at the corners facing the inclined surface 141. The recessed portions 144 are structures for maintaining a good joint at the relevant portions by avoiding interference between the corners of the inclined surface forming member 14 and protrusions such as rounded portions or welding buildups that exist in the portions of the beam 1 that abut the above-mentioned corners. The recessed portions 144 may be formed as grooves or recesses of a size and shape that can absorb the shapes of various protrusions present in the beam 1 and perform the above-mentioned function.

[0041] 5 and 6, the inclined surface forming member 14 is preferably configured such that fixing magnets 145 are embedded in the other two surfaces other than the surface constituting the inclined surface 141, i.e., the vertical surface 142 and / or the horizontal surface 143. In this case, the fixing magnets 145 are preferably embedded in such a manner that the surface of each magnet is flush with the surface of each embedded surface (the vertical surface 142 and / or the horizontal surface 143), leaving only the surface of each magnet exposed. This can facilitate the installation of the inclined surface forming member 14 on the beam 1 and further improve the stability of the inclined surface forming member 14 relative to the beam 1 after installation.

[0042] The inclined surface forming member 14 having the fixing magnet 145 in the above-described embodiment can be easily installed on an existing frame. Furthermore, by installing the inclined surface forming member 14 on the beam 1 using the magnetic force of the fixing magnet 145, welding for joining is not required, and there is no risk of the heat from the welding work affecting the frame and reducing its strength. Nondestructive testing to confirm the soundness of the weld is also not required. Furthermore, installation using the magnetic force of the fixing magnet 145 is preferable to installation using bolts because it does not require the provision of through-holes for inserting bolts, which would reduce strength.

[0043] The method for covering the lower flange to form the inclined surface is not limited to the above-described embodiment. For example, a stay (metal fitting) bent into a "L" shape may be used, with a fixing magnet 145 for attaching to the lower flange 11 attached to one of the bent surfaces, and a sliding plate for sliding the ore attached to the end of the other surface to form an inclined surface for sliding the ore down.

[0044] <Ore transport equipment> The ore conveying equipment 100 of the present invention can be constructed by placing an ore conveying path 3 for conveying ore, etc., on the upper side of the beam 1 of the ore conveying path stand 10, either directly or via another member. The ore conveying path 3 may specifically be a belt conveyor, or as shown in FIG. 1, may be a running rail of a stacker device 4. The stacker device 4 is a cargo handling machine having a stacker device main body 41 that runs on a running rail and a boom 42 with a swiveling belt conveyor (see Patent Document 1). The ore conveying equipment of the present invention is not limited to the above-mentioned belt conveyor or stacker device, and is a technology that can be applied to various ore conveying facilities in general where conveyed objects such as ore may fall or scatter.

[0045] For example, when ore is stacked by the ore transport equipment 100 in which the stacker device 4 is arranged on the ore transport path (traveling rail) 3 on the platform 10, the ore that would conventionally fall and pile up on the lower flange 11 can be made to slide down the inclined surface 141 and quickly fall downward at any time. This makes it possible to prevent the ore from piling up on the surface of the lower flange 11, and furthermore, when the ore is stacked up to a height that interferes with the lower flange 11, it is also possible to prevent the stacked ore from remaining on the lower flange.
