[0006] The problem that the invention aims to solve

[0007] However, the fixing component and the rope safety component are parallel to each other. Therefore, if the fixing component is not parallel to the rope pulley, the rope safety component cannot be made parallel to the rope pulley. As a result, it is difficult to adjust the gap between each of the multiple ropes hanging on the rope pulley and the fixing component individually and evenly.

[0008] The present invention was made to solve the problems mentioned above, and its object is to provide a rope derailment device that enables the rope protection component to be parallel to the rope pulley and a method for adjusting the gap of the rope derailment device.

[0009] Methods for solving problems

[0010] The rope anti-derailment device of the present invention comprises: a fixing member, which is disposed opposite to the rope hanging on the rope sheave and fixed to the housing of a traction machine; a first adjusting member, which is supported on the fixing member and is movable relative to the fixing member along the axial direction of the rope sheave; a second adjusting member, which is supported on the fixing member and is disposed axially separate from the first adjusting member and is movable relative to the fixing member along the axial direction; a first adjusting bolt, which is disposed in a manner that allows it to move relative to the fixing member, thereby causing the first adjusting member to move axially; a second adjusting bolt, which is disposed in a manner that allows it to move relative to the fixing member, thereby causing the second adjusting member to move axially; and a rope protection member, which is disposed between the rope and the fixing member and is supported on the fixing member by means of the first and second adjusting members. The rope protection member has a first inclined surface that contacts the first adjusting member and a second inclined surface that contacts the second adjusting member. By moving the first adjusting member, the first inclined surface moves radially along the rope sheave by means of the first adjusting member, and by moving the second adjusting member, the second inclined surface moves radially by means of the second adjusting member.

Detailed Implementation

[0023] Implementation Method 1

[0024] Figure 1 This is a side view showing the rope anti-derailment device of Embodiment 1. The rope anti-derailment device of Embodiment 1 is installed on an elevator traction machine 1. The elevator traction machine 1 includes a traction machine housing 101 and a rope pulley 102. A plurality of rope grooves 103 are formed in the rope pulley 102. A rope 2 is hung in each of the plurality of rope grooves 103.

[0025] The direction along the axis of the rope pulley 102 is defined as axial direction D1. In a plane perpendicular to the axis of the rope pulley 102, the direction along the radius of the circle centered on the axis of the rope pulley 102 is defined as radial direction D2. Multiple rope grooves 103 are arranged along axial direction D1. Therefore, multiple ropes 2 are arranged along axial direction D1.

[0026] The rope anti-derailment device of Embodiment 1 includes a fixing component 3, a first adjusting component 4, a second adjusting component 5, a first adjusting bolt 6, a second adjusting bolt 7, a rope protection component 8, and a pair of fixing bolts 9. Furthermore, the rope anti-derailment device of Embodiment 1 includes a locking nut 10, a locking nut 11, and a pair of locking nuts 12.

[0027] The fixing component 3 is fixed to the traction machine housing 101. The fixing component 3 includes a mounting part 301, a base part 302, a first arm part 303, and a second arm part 304.

[0028] Mounting part 301 is mounted to traction machine housing 101 by means of multiple fastening bolts 13. Base part 302 extends from mounting part 301 in a direction away from traction machine housing 101 in the axial direction D1. First arm part 303 and second arm part 304 are respectively provided on base part 302. First arm part 303 and second arm part 304 are separated from each other in the axial direction D1. Second arm part 304 is located on the side closer to mounting part 301 than first arm part 303.

[0029] The first arm portion 303 includes: a first plate portion 305 extending from the base portion 302 in a radial direction D2 toward the pulley 102; and a second plate portion 306 extending from the front end of the first plate portion 305 in an axial direction D1 toward the second arm portion 304. A threaded hole 307 is formed in the first plate portion 305, extending through the axial direction D1.

[0030] The second arm portion 304 includes: a first plate portion 308 extending from the base portion 302 in a radial direction D2 toward the pulley 102; and a second plate portion 309 extending from the front end of the first plate portion 308 in an axial direction D1 toward the first arm portion 303. A threaded hole 310 is formed in the first plate portion 308, extending through the axial direction D1.

[0031] A pair of threaded holes 311 are formed in the base 302, which pass through the radial direction D2. The pair of threaded holes 311 are arranged separately from each other in the axial direction D1.

[0032] The first adjusting member 4 is supported on the fixed member 3. Specifically, the first adjusting member 4 is mounted on the second plate portion 306 of the first arm portion 303. The first adjusting member 4 is movable relative to the fixed member 3 along the axial direction D1. The first adjusting member 4 is formed in a wedge shape.

[0033] The second adjusting member 5 is supported on the fixed member 3. Specifically, the second adjusting member 5 is mounted on the second plate portion 309 of the second arm portion 304. The second adjusting member 5 is movable relative to the fixed member 3 along the axial direction D1. The second adjusting member 5 is formed in a wedge shape.

[0034] The second adjusting member 5 is disposed separately from the first adjusting member 4 in the axial direction D1. The first adjusting member 4 is configured such that its radial thickness D2 decreases as it approaches the second adjusting member 5 in the axial direction D1. The second adjusting member 5 is configured such that its radial thickness D2 decreases as it approaches the first adjusting member 4 in the axial direction D1.

[0035] The first adjusting bolt 6 is configured to move axially D1 relative to the fixed component 3. Specifically, the first adjusting bolt 6 is inserted into the threaded hole 307 of the first arm 303. By rotating the first adjusting bolt 6, the first adjusting bolt 6 can move axially D1 relative to the first arm 303.

[0036] The first adjusting member 4 moves along the axial direction D1 by moving the first adjusting bolt 6. Specifically, the first adjusting member 4 is positioned closer to the second arm 304 than the first adjusting bolt 6. The front end of the first adjusting bolt 6 contacts the first adjusting member 4. Therefore, by moving the first adjusting bolt 6 towards the second arm 304, the first adjusting member 4 is pressed by the first adjusting bolt 6 and moves towards the second arm 304.

[0037] The second adjusting bolt 7 is configured to move axially D1 relative to the fixed member 3. Specifically, the second adjusting bolt 7 is inserted into the threaded hole 310 of the second arm 304. By rotating the second adjusting bolt 7, the second adjusting bolt 7 can move axially D1 relative to the second arm 304.

[0038] The second adjusting member 5 moves along the axial direction D1 by moving the second adjusting bolt 7. Specifically, the second adjusting member 5 is positioned closer to the first arm portion 303 than the second adjusting bolt 7. The front end of the second adjusting bolt 7 contacts the second adjusting member 5. Therefore, by moving the second adjusting bolt 7 towards the first arm portion 303, the second adjusting member 5 is pressed by the second adjusting bolt 7 and moves towards the first arm portion 303.

[0039] A rope protection element 8 is disposed between the rope 2 and the fixing member 3. The rope protection element 8 is supported on the fixing member 3 by means of a first adjusting member 4 and a second adjusting member 5. The rope protection element 8 is positioned directly above the rope pulley 102. The rope protection element 8 includes a mounting part 801, a rope protection element body 802, and a connecting part 803.

[0040] The mounting portion 801 is disposed in the axial direction D1 between the first arm portion 303 and the second arm portion 304. The mounting portion 801 has a first inclined surface 804 that contacts the first adjusting member 4 and a second inclined surface 805 that contacts the second adjusting member 5.

[0041] The first inclined surface 804 and the second inclined surface 805 are separated from each other in the axial direction D1. The second inclined surface 805 is located on the side closer to the mounting portion 301 than the first inclined surface 804.

[0042] The rope protection body 802 is positioned radially D2 closer to the rope 2 than the fixing member 3. The rope protection body 802 is radially opposite to multiple ropes 2. For example, in the event of an earthquake, the ropes 2 vibrate. In the event of rope 2 vibration, the rope protection body 802 prevents the ropes 2 from slipping out of the rope groove 103.

[0043] The connecting part 803 connects the mounting part 801 to the rope protection body 802. The connecting part 803 passes radially D2 between the second plate part 306 of the first arm part 303 and the second plate part 309 of the second arm part 304.

[0044] Figure 2 It is shown Figure 1 An enlarged view of the first inclined surface 804 being pushed upwards. Figure 3 It is shown Figure 1 An enlarged view of the first inclined surface 804 descending due to its own weight. The first inclined surface 804 is configured to approach the pulley 102 as it approaches the second inclined surface 805.

[0045] The first adjusting member 4 contacts the first inclined surface 804 from below. The surface of the first adjusting member 4 that contacts the first inclined surface 804 is configured to approach the pulley 102 as it approaches the second adjusting member 5.

[0046] The first inclined surface 804 moves radially D2 by moving the first adjusting member 4 along the axial direction D1. Specifically, the first inclined surface 804 moves away from the rope pulley 102 by moving the first adjusting member 4 toward the second adjusting member 5. On the other hand, the first inclined surface 804 moves toward the rope pulley 102 by moving the first adjusting member 4 away from the second adjusting member 5, causing it to move closer to the rope pulley 102 due to its own weight.

[0047] Figure 4 It is shown Figure 1 An enlarged view of the second inclined surface 805 being pushed upwards. Figure 5 It is shown Figure 1 An enlarged view of the second inclined surface 805 descending due to its own weight. The second inclined surface 805 is configured to approach the pulley 102 as it approaches the first inclined surface 804.

[0048] The second adjusting member 5 contacts the second inclined surface 805 from below. The surface of the second adjusting member 5 that contacts the second inclined surface 805 is configured to approach the pulley 102 as it approaches the first adjusting member 4.

[0049] The second inclined surface 805 moves radially D2 by moving the second adjusting member 5 along the axial direction D1. Specifically, the second inclined surface 805 moves away from the rope pulley 102 by moving the second adjusting member 5 towards the first adjusting member 4. On the other hand, the second inclined surface 805 moves towards the rope pulley 102 due to its own weight by moving the second adjusting member 5 away from the first adjusting member 4.

[0050] like Figure 1As shown, a pair of fixing bolts 9 are disposed on the base 302 of the fixing member 3. Specifically, the pair of fixing bolts 9 are respectively inserted into a pair of threaded holes 311 in the base 302. By rotating each fixing bolt 9, the fixing bolt 9 moves radially D2 relative to the fixing member 3.

[0051] The fixing bolt 9 can contact the rope protection member 8 from the outside in the radial direction D2. The contact between the fixing bolt 9 and the rope protection member 8 restricts the outward movement of the first inclined surface 804 and the second inclined surface 805 in the radial direction D2. Without the first inclined surface 804 moving towards the pulley 102 due to its own weight, the operator operates the fixing bolt 9, causing the fixing bolt 9 to move towards the pulley 102. This movement of the fixing bolt 9 towards the pulley 102 presses the rope protection member 8 down, and the first inclined surface 804 moves towards the pulley 102. Similarly, without the second inclined surface 805 moving towards the pulley 102 due to its own weight, the operator operates the fixing bolt 9, causing the fixing bolt 9 to move towards the pulley 102. This movement of the fixing bolt 9 towards the pulley 102 presses the rope protection member 8 down, and the second inclined surface 805 moves towards the pulley 102.

[0052] The locking nut 10 is installed on the first adjusting bolt 6. By rotating the locking nut 10, the locking nut 10 moves axially relative to the first adjusting bolt 6. By contacting the first arm portion 303, the locking nut 10 fixes the first adjusting bolt 6 relative to the first arm portion 303.

[0053] The locking nut 11 is installed on the second adjusting bolt 7. By rotating the locking nut 11, the locking nut 11 moves axially relative to the second adjusting bolt 7. By contacting the second arm 304, the locking nut 11 fixes the second adjusting bolt 7 relative to the second arm 304.

[0054] A pair of locking nuts 12 are respectively installed on a pair of fixing bolts 9. By rotating the locking nut 12, the locking nut 12 moves axially relative to the corresponding fixing bolt 9. By contacting the base 302, the corresponding fixing bolt 9 is fixed relative to the base 302.

[0055] Next, the process of adjusting the gap S between the rope 2 and the rope protection member 8 using the rope anti-loosening device of Embodiment 1 will be described. Figure 6 This is a flowchart illustrating the gap adjustment method of the rope anti-loosening device according to Embodiment 1. The gap adjustment method of the rope anti-loosening device according to Embodiment 1 includes a first step S101, a second step S102, and a third step S103.

[0056] In the first step S101, the first adjusting bolt 6 and the second adjusting bolt 7 are moved in directions that separate them from each other, so that the rope protection member 8 comes into contact with the multiple ropes 2 respectively.

[0057] Next, in the second step S102, starting from the state where the rope protection member 8 is in contact with each rope 2, the first adjusting bolt 6 and the second adjusting bolt 7 are moved towards each other. By moving the first adjusting bolt 6 and the second adjusting bolt 7 along the axial direction D1, the first adjusting component 4 and the second adjusting component 5 are moved along the radial direction D2, thereby adjusting the size L of the gap S between the rope 2 and the rope protection member 8. The adjustment of the size L of the gap S is performed by the operator while visually observing the gap S.

[0058] When the base 302 of the fixed component 3 is not parallel to the rope pulley 102, the movement of the first adjusting component 4 and the second adjusting component 5 is adjusted so that the rope protection component 8 is parallel to the rope pulley 102. By making the rope protection component 8 parallel to the rope pulley 102, the gap S between each of the multiple ropes 2 hanging on the rope pulley 102 and the rope protection component body 802 of the rope protection component 8 is adjusted evenly.

[0059] When the position of the rope protection member 8 relative to the rope pulley 102 in the axial direction D1 is deviated, the first adjusting bolt 6 and the second adjusting bolt 7 are moved by the same distance in the same direction. Consequently, the first adjusting component 4 and the second adjusting component 5 are moved by the same distance in the same direction. As a result, the dimension L of the gap S between the rope protection member 8 and the rope 2 remains unchanged, and the position of the rope protection member 8 relative to the rope pulley 102 in the axial direction D1 is adjusted.

[0060] Next, in the third step S103, a pair of fixing bolts 9 are brought into contact with the base 302. Furthermore, in the third step S103, the first adjusting bolt 6 is fixed relative to the first arm 303 using a locking nut 10. Furthermore, in the third step S103, the second adjusting bolt 7 is fixed relative to the second arm 304 using a locking nut 11. Furthermore, in the third step S103, a pair of fixing bolts 9 are respectively fixed relative to the base 302 using a pair of locking nuts 12. Thus, the process of adjusting the gap S between the rope 2 and the rope protection member 8 using the rope anti-derailment device of Embodiment 1 is completed.

[0061] As described above, the rope anti-derailment device of Embodiment 1 includes a fixing member 3, a first adjusting member 4, a second adjusting member 5, a first adjusting bolt 6, a second adjusting bolt 7, and a rope protection member 8. The fixing member 3 is disposed opposite to the rope 2 hanging on the rope pulley 102 and fixed to the traction machine housing 101. The first adjusting member 4 is supported by the fixing member 3 and is movable relative to the fixing member 3 along the axial direction D1. The second adjusting member 5 is supported by the fixing member 3 and is disposed separately from the first adjusting member 4 along the axial direction D1, and is movable relative to the fixing member 3 along the axial direction D1. The first adjusting bolt 6 is disposed in a manner that allows it to move relative to the fixing member 3, thereby moving the first adjusting member 4 along the axial direction D1. The second adjusting bolt 7 is disposed in a manner that allows it to move relative to the fixing member 3, thereby moving the second adjusting member 5 along the axial direction D1. The rope protection member 8 is disposed between the rope 2 and the fixing member 3 and is supported by the fixing member 3 by means of the first adjusting member 4 and the second adjusting member 5. The rope protection member 8 has a first inclined surface 804 that contacts the first adjusting member 4 and a second inclined surface 805 that contacts the second adjusting member 5. Movement of the first adjusting member 4 causes the first inclined surface 804 to move radially D2, and movement of the second adjusting member 5 causes the second inclined surface 805 to move radially D2. With this structure, when the base 302 of the fixing member 3 is not parallel to the rope pulley 102, the amount of movement of the first inclined surface 804 and the second inclined surface 805 in the radial direction D2 can be adjusted to make the rope protection member 8 parallel to the rope pulley 102. Thus, the rope protection member 8 can be made parallel to the rope pulley 102.

[0062] Furthermore, the gap adjustment method of the rope anti-derailment device in Embodiment 1 includes a first step S101 and a second step S102. In the first step S101, the rope protection member 8 is brought into contact with the rope 2. In the second step S102, the gap S is adjusted by moving the first adjusting bolt 6 and the second adjusting bolt 7 respectively from the state where the rope protection member 8 is in contact with the rope 2, thereby moving the first adjusting member 4 and the second adjusting member 5 respectively. According to this structure, when the base 302 of the fixing member 3 is not parallel to the rope pulley 102, the amount of movement in the radial direction D2 of the first inclined surface 804 and the second inclined surface 805 can be adjusted so that the rope protection member 8 is parallel to the rope pulley 102. Thus, the rope protection member 8 can be made parallel to the rope pulley 102.

[0063] Implementation Method 2

[0064] Figure 7 This is a side view showing the first adjusting component of the rope anti-loosening device according to Embodiment 2. Figure 8This is a side view showing the second adjusting member of the rope anti-loosening device according to Embodiment 2. In the rope anti-loosening device of Embodiment 2, the first adjusting member 4 has a first hemisphere 401 and a first moving part 402, and the second adjusting member 5 has a second hemisphere 501 and a second moving part 502.

[0065] A convex hemispherical surface 403 and a flat surface 404 are formed in the first hemispherical portion 401. A concave hemispherical surface 405 is formed in the first movable portion 402, which contacts the convex hemispherical surface 403 of the first hemispherical portion 401. The radius of the convex hemispherical surface 403 and the radius of the concave hemispherical surface 405 are the same. The first hemispherical portion 401 is rotatable relative to the first movable portion 402 inside the concave hemispherical surface 405.

[0066] The orientation of the plane 404 changes as the first hemisphere 401 rotates relative to the first moving part 402. The first hemisphere 401 rotates relative to the first moving part 402 so that the plane 404 of the first hemisphere 401 is parallel to the first inclined surface 804. The plane 404 of the first hemisphere 401 contacts the first inclined surface 804. The front end of the first adjusting bolt 6 contacts the first moving part 402.

[0067] A convex hemisphere 503 and a flat surface 504 are formed in the second hemisphere 501. A concave hemisphere 505 is formed in the second moving part 502, which contacts the convex hemisphere 503 of the second hemisphere 501. The radius of the convex hemisphere 503 and the radius of the concave hemisphere 505 are the same. The second hemisphere 501 is rotatable relative to the second moving part 502 inside the concave hemisphere 505.

[0068] The orientation of the plane 504 changes as the second hemisphere 501 rotates relative to the second moving part 502. The second hemisphere 501 rotates relative to the second moving part 502 so that the plane 504 of the second hemisphere 501 is parallel to the second inclined surface 805. The plane 504 of the second hemisphere 501 contacts the second inclined surface 805. The front end of the second adjusting bolt 7 contacts the second moving part 502.

[0069] The other structures in the rope anti-loosening device of Embodiment 2 are the same as those in Embodiment 1.

[0070] As explained above, in the rope anti-derailment device of Embodiment 2, the first adjusting member 4 includes a first hemisphere 401 and a first moving part 402. The first hemisphere 401 has a convex hemisphere 403 and a plane 404. The first moving part 402 has a concave hemisphere 405 that contacts the convex hemisphere 403 of the first hemisphere 401. The plane 404 of the first hemisphere 401 contacts the first inclined surface 804. With this structure, the first hemisphere 401 rotates relative to the first moving part 402 such that the plane 404 of the first hemisphere 401 is parallel to the first inclined surface 804. This allows the plane 404 to contact the first inclined surface 804.

[0071] Furthermore, in the rope anti-loosening device of Embodiment 2, the second adjusting member 5 includes a second hemisphere 501 and a second moving part 502. The second hemisphere 501 has a convex hemisphere 503 and a plane 504. The second moving part 502 has a concave hemisphere 505 that contacts the convex hemisphere 503 of the second hemisphere 501. The plane 504 of the second hemisphere 501 contacts the second inclined surface 805. According to this structure, the second hemisphere 501 rotates relative to the second moving part 502 such that the plane 504 of the second hemisphere 501 is parallel to the second inclined surface 805. This allows the plane 504 to contact the second inclined surface 805.

[0072] Furthermore, in each embodiment, a structure in which the rope protection member 8 is positioned directly above the rope pulley 102 has been described. However, it is also possible to have a structure in which the rope protection member 8 is positioned at a location offset circumferentially from directly above the rope pulley 102.

[0073] The preferred embodiments of the rope anti-loosening device have been described above, but the invention is not limited to the rope anti-loosening devices of the above embodiments. Various modifications and alterations can be made to the rope anti-loosening devices of the above embodiments without departing from the scope of the claims.
