Wire rope oil removal device

Abstract

To provide a wire rope oil removal device which can be installed at a proper position at all times regardless of an installation site of a wire rope.SOLUTION: An external hanging member 40 is connected to each connection member 34 to cause a support unit 30 to be disposed hanging from the hanging members 40. Further, in the support unit 30, displacement of a wire rope 1 is restricted at two points in a longitudinal direction of the wire rope 1 by guide holes 31c of a pair of guide members 31 which is disposed spaced apart from each other in the longitudinal direction of the wire rope 1, and thus the support unit 30 does not incline significantly even when receiving vibration or impact. Further, the guide members 31 are connected by a plurality of connection members 33 which is disposed spaced apart from each other in a circumferential direction of the guide members 31. The structure allows reduction of the weight of the support unit 30 and causes an oil removed from the wire rope 1 by an oil removing member 10 to pass through gaps between the connection members 33, thereby preventing adhesion of the oil to the support unit 30.SELECTED DRAWING: Figure 13

Description

[Technical Field]

[0001] The present invention relates to a wire rope oil removal device for removing oil from wire ropes used to open and close gates of water gates installed in rivers, dams, etc. [Background technology]

[0002] Generally, the gates of sluice gates installed on rivers, dams, etc. are opened by winding up the wire rope connected to the gate with a winch, and closed by unwinding the wire rope from the winch. The surface of the wire rope is coated with oil such as grease for lubrication and rust prevention, and the oil on the wire rope is regularly reapplied during maintenance and inspection of the sluice gate.

[0003] In this case, it is necessary to remove the old oil adhering to the wire rope, and in the case of a wire rope made of stranded wire, the oil must also be removed from within the spiral grooves. However, since the work of removing oil from the wire rope is done manually, it requires a great deal of human effort and places a heavy burden on the worker.

[0004] Therefore, a method is known in which oil removal from wire ropes can be performed without manual intervention, in which the wire rope is inserted into an oil removal member having a hole formed in a shape identical to the cross-sectional shape of the wire rope, and the oil is removed from the surface of the wire rope by the oil removal member while the wire rope is passed through the oil removal member (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2003-190888 Summary of the Invention [Problem to be solved by the invention]

[0006] In the device described in Patent Document 1, the oil removing member rotates due to the spiral groove of the wire rope passing through the oil removing member, so the oil removing member is rotatably supported by a plate-shaped support member, and the movement of the oil removing member relative to the wire rope is restricted by the support member. In this case, the support member is fixed to a frame or the like inside the machine room, and the oil removing member rotates while being supported by the support member.

[0007] However, for example, inside the machinery room of a floodgate, many pieces of equipment and their accessories are arranged in a complex manner, so there may be limited places where the oil removal member can be installed, and if there is no frame or the like to fix the support member around the wire rope, there is a problem that the oil removal member cannot be installed in an appropriate position.

[0008] The present invention has been made in consideration of the above-mentioned problems, and its purpose is to provide a wire rope oil removal device that can always be installed in an appropriate position regardless of the location of the wire rope. [Means for solving the problem]

[0009] In order to achieve the above object, the present invention provides a wire rope oil removal device for removing oil adhering to the surface of a wire rope while passing the wire rope having a spiral groove on its outer circumferential surface, the device comprising: a plate-shaped oil removal member having an insertion hole for inserting the wire rope, the insertion hole being formed in a shape equivalent to the cross-sectional shape of the wire rope; a cover member having an opening for inserting the wire rope and removably attached to the oil removal member so as to cover the peripheral side of the oil removal member; and a support member for supporting the oil removal member with the cover member attached from one longitudinal direction of the wire rope, the cover member being formed so as to be able to accommodate the wire rope from the radial direction inside. The support unit has a pair of guide members spaced apart from each other in the longitudinal direction of the wire rope, a plurality of connecting members connecting the guide members, a support member that supports the oil removal member with the cover member attached so that it can rotate circumferentially relative to the guide members and move radially relative to the guide members, and a connecting member that can be connected to an external hanging member, and each guide member has a guide hole through which the wire rope is inserted, and the connecting members are spaced apart from each other in the circumferential direction of the wire rope, and the support member is provided on one of the guide members that is located on the oil removal member side.

[0010] As a result, by connecting an external suspension member to each connecting member, the support unit is suspended by the suspension member. Furthermore, in the support unit, the guide holes of a pair of guide members, which are spaced apart in the longitudinal direction of the wire rope, restrict the displacement of the wire rope at two points in the longitudinal direction of the wire rope, so the support unit does not tilt significantly even when subjected to vibration or impact. Furthermore, since the guide members are connected to each other by multiple connecting members spaced apart in the circumferential direction of the guide members, the support unit is lightweight, and oil removed from the wire rope by the oil removal member passes through the gaps between the connecting members, preventing oil from adhering to the support unit. [Effects of the Invention]

[0011] According to the present invention, the support unit can be suspended and positioned using the suspension member, so that it can be installed in an appropriate position even in places where many pieces of equipment and their accessories are arranged in a complex manner, such as the machine room of a floodgate, where there is no frame or the like for securing the support unit around the wire rope. Furthermore, the support unit does not tilt significantly even when subjected to vibration or impact, so the support unit can always stably support the oil removal member. Furthermore, the support unit can be made lighter, which reduces the labor required for installation and suppresses oil adhesion to the support unit, making it easy to maintain the support unit after the oil removal work is completed.

[0013] 1 to 14 show an embodiment of the present invention, which shows a wire rope oil removal device for removing oil such as grease from a wire rope used to open and close a water gate of a river, a dam, etc.

[0014] The wire rope 1 shown in the same figure is formed by twisting together multiple strands 1a, for example made of metal, around a core rope 1b at a predetermined pitch, and one end is connected to the gate body of a floodgate (not shown), and the other end is connected to a winch (not shown).

[0015] The wire rope oil removal device of this embodiment is composed of an oil removal member 10 that removes oil from the surface of the wire rope 1, a cover member 20 that covers the peripheral side of the oil removal member 10, and a support unit 30 that supports the oil removal member 10 with the cover member 20 attached from one side of the longitudinal direction of the wire rope 1, and the cover member 20 is designed to be attached and detached freely to the oil removal member 10.

[0016] The oil removal member 10 is made of elastically deformable disc-shaped rubber, and has an insertion hole 11 in the radial center for inserting the wire rope 1, with the insertion hole 11 being formed in a shape similar to the cross-sectional shape of the wire rope 1. That is, the insertion hole 11 is formed so that multiple approximately semicircular inner peripheral surfaces that follow the outer periphery of each strand 1a of the wire rope 1 are continuous in the circumferential direction, and is formed so as to fit closely with the surface of the wire rope 1 without any gaps. The oil removal member 10 also has notches 12 that extend radially from the insertion hole 11 to the outer periphery, and can be attached to the wire rope 1 by elastically deforming the member to open the notches 12.

[0017] The cover member 20 is a circular, hollow member that is detachably attached to the oil removal member 10 and is formed by a pair of semicircular sections 21, 22. The sections 21, 22 are detachably connected to each other by a pair of bolts 23. One of the sections 21 has holes 21a at both circumferential ends for inserting the bolts 23, and the other section 22 has threaded holes 22a at both circumferential ends for threading the bolts 23. Circular openings 20a, 20b for inserting the wire rope 1 are provided on one and the other thickness-wise surfaces of the cover member 20, respectively, so that the cover member 20 covers the outer peripheral surface and the peripheral edges of both thickness-wise surfaces of the oil removal member 10. In this case, the opening 20a on the upper surface of the cover member 20 in the figure is formed with a larger inner diameter than the opening 20b on the lower surface.

[0018] The support unit 30 comprises a pair of disk-shaped guide members 31 arranged at intervals along the longitudinal direction of the wire rope 1, a plurality of support members 32 that support the oil removal member 10 to which the cover member 20 is attached so that it can rotate freely in the circumferential direction and move freely in the radial direction, and a plurality of connecting members 33 that connect each guide member 31 to each other at intervals, and some of the connecting members 33 are provided with a pair of connecting members 34 that can be connected to an external hanging member 40.

[0019] Each guide member 31 is composed of a pair of semicircularly divided sections 31a, 31b, each with a circular guide hole 31c at its radial center through which the wire rope 1 can be inserted. The divided sections 31a, 31b are rotatably connected at one circumferential end by a pivotal connector 31d, and the guide hole 31c is opened and closed by pivoting around the pivotal connector 31d. The other circumferential end of each divided section 31a, 31b is provided with a recess 31e and a protrusion 31f that engage with each other, each of which is semicircular. When the divided sections 31a, 31b are closed, the recess 31e and the protrusion 31f engage with each other in the circumferential direction of the guide member 31, and the protrusion 31f is configured to engage with the recess 31e in the thickness direction of each guide member 31.

[0020] Each support member 32 is made of a well-known free ball bearing consisting of a sphere 32a that abuts the underside of the cover member 20 in the figure and a holder 32b that supports the sphere 32a so that it can roll freely, and is attached to the upper surface of one of the guide members 31 in the figure at intervals around the circumferential direction of the guide member 31.

[0021] Each connecting member 33 is made of a columnar member extending in the longitudinal direction of the wire rope 1, and both longitudinal ends are joined to the opposing surfaces of each guide member 31. As a result, the support unit 30 is configured so that the divided parts 31a, 31b of each guide member 31 open and close integrally with the connecting member 32, with the pivotal coupling part 31d as a fulcrum. In addition, a pair of connecting members 33 located respectively on the circumferential center side of each divided part 31a, 31b of each connecting member 33 are formed with mounting holes 33a extending in the longitudinal direction of the connecting members 33 for mounting a coupling member 34.

[0022] Each connecting member 34 has an annular connecting portion 34a to which the hanging member 40 is connected, and is fixed to the connecting member 33 by a bolt 34b that is inserted through a mounting hole 33a of the connecting member 33. This makes the position of the connecting member 34 movable along the mounting hole 33a by loosening the bolt 34b.

[0023] The support unit 30 is also provided with a well-known locking mechanism 35, consisting of a so-called snap lock, that locks the support unit 30 in a closed state. The locking mechanism 35 includes a hook 35a attached to the connecting member 33 located at the other circumferential end of one guide member 31, a base 35b attached to the connecting member 33 located at the other circumferential end of the other guide member 31, a joint 35c engageable at one end with the hook 35a, and an opening / closing lever 35d rotatably connected at one end to the base 35b and at the other end to the joint 35c. The locking mechanism 35 is provided at two locations, one above the other in the figure, on the connecting member 33. That is, the locking mechanism 35 is locked by engaging the joint 35c with the hook 35a and rotating the opening / closing lever 35d in one direction, and is unlocked by rotating the opening / closing lever 35d in the other direction to disengage the joint 35c from the hook 35a. The joint 35c may be expanded or contracted by a spring.

[0024] The wire rope oil removal device configured as above is attached to a wire rope 1 extending in the vertical direction as shown in FIG. 13, and is designed to remove oil from the wire rope 1.

[0025] When the wire rope oil removal device of this embodiment is installed, the oil removal member 10 is elastically deformed to open the slit 12, and the wire rope 1 is placed in the insertion hole 11, thereby installing the device on the wire rope 1.

[0026] Next, the divided parts 21 and 22 of the cover member 20 are engaged with the oil removal member 10 and fastened together with bolts 23, thereby attaching the cover member 20 to the oil removal member 10.

[0027] 11, the wire rope 1 is accommodated from the radial direction inside the open support unit 30, and as shown in FIG. 12, the support unit 30 is closed to lock the locking mechanisms 35, and the suspending members 40 are connected to the connecting members 34 of the support unit 30. As a result, as shown in FIG. 13, the support unit 30 is suspended by the suspending members 40 with the wire rope 1 inserted therethrough, and the oil removal member 10 with the cover member 20 attached is supported by the support members 32 of the support unit 30. In this case, various members capable of suspending the support unit 30, such as a wire, a chain, or a turnbuckle, can be used for each suspending member 40.

[0028] Thereafter, the wire rope 1 is unwound or wound with a winch (not shown), thereby moving it downward relative to the wire rope oil removal device as indicated by the solid arrow in Fig. 13. As a result, the wire rope 1 passes through the insertion hole 11 of the oil removal member 10 as shown in Figs. 13 and 14. At this time, because the insertion hole 11 is formed in a shape identical to the cross-sectional shape of the wire rope 1, the insertion hole 11 is guided by the spiral grooves between the strands 1a of the wire rope 1, and the oil removal member 10 rotates together with the cover member 20 as indicated by the dashed arrow in the figures. Furthermore, because the inner surface of the insertion hole 11 is in close contact with the surface of the wire rope 1 with no gaps, the edge of the insertion hole 11 scrapes off the oil 2 from the entire surface of the wire rope 1, including the spiral grooves.

[0029] At this time, the oil 2 scraped off by the oil removal member 10 falls from the upper surface of the oil removal member 10 to the surrounding area, but since the support unit 30 is formed by a pair of guide members 31 arranged at a distance from each other and a plurality of columnar connecting members 33 connecting each guide member 31, the oil 2 passes through the gaps between each connecting member 33, and adhesion of the oil 2 to the support unit 30 is suppressed.

[0030] In addition, when the wire rope 1 passes through the oil removal member 10, the movement of the oil removal member 10 in the feed direction of the wire rope 1 is restricted by the support unit 30, and the rolling of the balls 32a of each support member 32 abutting against the cover member 20 allows the oil removal member 10 to rotate and move radially relative to the support unit 30.

[0031] At this time, the support unit 30 receives a reaction force due to the resistance when the wire rope 1 passes through the oil removal member 10, and so its position and orientation relative to the wire rope 1 tend to change due to vibration or impact, but the displacement of the support unit 30 is restricted within the range of the guide holes 31c of each guide member 31. In this case, the pair of guide members 31 restrict the displacement of the wire rope 1 at two points in the longitudinal direction, so the support unit 30 does not tilt significantly around the connection points (connecting members 34) with each hanging member 40.

[0032] As described above, the wire rope oil removal device of this embodiment comprises an oil removal member 10 that removes oil from the surface of the wire rope 1, a cover member 20 that covers the peripheral edge of the oil removal member 10, and a support unit 30 that supports the oil removal member 10 with the cover member 20 attached from one longitudinal direction of the wire rope 1, and since the support unit 30 is provided with a plurality of connecting members 34 that can be connected to an external hanging member 40, the support unit 30 can be suspended and positioned by the hanging member 40. This allows the oil removal member 10 to be installed in an appropriate position even in a place where many pieces of equipment and their accessories are arranged in a complex manner, such as the machine room of a water gate, and where there is no frame or the like for fixing the support unit 30 around the wire rope 1.

[0033] In addition, the guide holes 31c of a pair of guide members 31, which are arranged at intervals in the longitudinal direction of the wire rope 1, can restrict the displacement of the wire rope 1 at two points in the longitudinal direction of the wire rope 1, so that the support unit 30 does not tilt significantly even when subjected to vibration or impact, and the oil removal member 10 can always be stably supported by the support unit 30.

[0034] Furthermore, since each guide member 31 is connected to another by a plurality of connecting members 33 arranged at intervals in the circumferential direction of the guide members 31, the weight of the support unit 30 can be reduced, and the labor required for installation can be reduced. In this case, the oil 2 removed from the wire rope 1 by the oil removal member 10 passes through the gaps between the connecting members 33, which prevents the oil 2 from adhering to the support unit 30, and makes it easy to maintain the support unit 30 after the oil removal work is completed.

[0035] In addition, the oil removal member 10 is made of an elastically deformable material and has a notch 12 formed from the insertion hole 11 to the outer peripheral surface, so that it can be attached to and detached from the wire rope 1 by elastically deforming it to open the notch 12, making it easy to attach and detach the oil removal member 10 to the wire rope 1.

[0036] Furthermore, the cover member 20 consists of a pair of divided parts 21, 22 divided radially into two, and each divided part 21, 22 is formed to be detachable from the other, so that the attachment and detachment work to the oil removal member 10 attached to the wire rope 1 can be easily performed.

[0037] Furthermore, the cover member 20 is formed so as to cover both sides of the oil removal member 10 in the thickness direction, and the opening 20a on one side of the oil removal member 10 in the thickness direction is formed to have a larger inner diameter than the opening 20b on the other side of the oil removal member in the thickness direction, so that by arranging the opening 20b with the smaller inner diameter on the support unit 30 side, the contact area between the cover member 20 and each support member 32 can be increased, and a sufficient range of movement of the oil removal member 10 relative to the support unit 30 can be ensured. In this case, the opening 20a with the larger inner diameter can reliably prevent interference between the cover member 20 and the wire rope 1 being fed toward the oil removal member 10.

[0038] Furthermore, each guide member 31 of the support unit 30 consists of a pair of divided parts 31, 32 divided radially into two, and is formed so as to be openable and closable by connecting one circumferential end of each divided part 31, 32 so that it can be rotated freely.Therefore, by opening each divided part 21, 22, the wire rope 1 can be easily inserted and removed from the support unit 30.

[0039] Furthermore, since each connecting member 34 of the support unit 30 is arranged so that its position can be moved in the longitudinal direction of the wire rope 1, by changing the position of each connecting member 34, interference between the hanging member 40 connected to each connecting member 34 and surrounding equipment can be prevented, and the balance of the support unit 30 can be adjusted, so that the support unit 30 can always be positioned in the appropriate position and orientation.

[0040] In the above embodiment, the support unit 30 is arranged vertically on the wire rope 1 extending in the vertical direction, but the support unit 30 can also be arranged horizontally or diagonally depending on the direction of the wire rope 1.

[0041] Furthermore, the above embodiment is an example of the present invention, and the present invention is not limited to the above embodiment. [Explanation of symbols]
