Description

[Technical Field]

[0001] The present invention relates to a rope connection mechanism and an elevator. [Background technology]

[0002] Conventionally, an elevator comprises a car, a counterweight, a main rope connecting the car and the counterweight, and a hoisting machine around which the main rope is wound. The elevator also includes a governor that constantly monitors the car's ascent and descent speed and activates an emergency stop device installed in the car if it exceeds a predetermined speed. Furthermore, the governor is equipped with a governor rope connected to the car. Additionally, the main rope and the governor rope are provided with rope coupling mechanisms to connect both ends.

[0003] Furthermore, the main rope and governor ropes elongate due to aging and other factors. Therefore, the elongation of the main rope and governor ropes is adjusted periodically. When adjusting the elongation of the ropes, the ropes are rotated axially until the strand pitch, or the twist of the rope, returns to the correct dimension.

[0004] One example of a technique for adjusting rope twisting is the one described in Patent Document 1. Patent Document 1 describes a technique comprising: a rope tension detection means that detects the rope tension generated in a rope suspended in a hoistway with its end secured by a rope stopper as deformation of an elastic body; and a rope rotation means that rotates the rope around its central axis in a direction that eliminates the twisting generated in the rope according to the value of the rope tension detected by the rope tension detection means.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-84199 Summary of the Invention [Problem to be solved by the invention]

[0006] However, with the technology described in Patent Document 1, there was a risk that the rope would rotate around the central axis against the user's intention even under normal conditions. As a result, with the technology described in Patent Document 1, there was a risk that the rope would rotate under normal conditions and stretch, making it difficult to easily adjust the length of the rope.

[0007] In consideration of the above problems, the object of this invention is to provide a rope connection mechanism and an elevator that can prevent the rope from rotating around the central axis under normal conditions and that can easily adjust the length of the rope during adjustment work. [Means for solving the problem]

[0008] To solve the above problems and achieve the present object, a rope connection mechanism is installed at the end of a rope provided in an elevator. The rope connection mechanism includes a rotating shaft to which the end of the rope is connected, a rotor provided on the rotating shaft, a cylindrical portion formed with a cylindrical hole for accommodating the rotor, and a bearing portion that supports the rotor so that it can rotate around the central axis of the rope. The rope connection mechanism also includes a rotation restriction member that releasably restricts the rotation of the rotor around the central axis of the rope.

[0009] The elevator also includes a body that ascends and descends within the hoistway, a main rope connected to the body, a governor that monitors the ascending and descending speed of the body and has a governor rope that circulates in accordance with the ascending and descending movement of the body, and a rope connection mechanism that is connected to the end of the main rope or the end of the governor rope. The rope connection mechanism described above is used as the rope connection mechanism. [Effects of the Invention]

[0010] According to the rope connection mechanism and elevator of the above configuration, the rope can be prevented from rotating around the central axis under normal conditions, and the length of the rope can be easily adjusted during adjustment work. [Brief explanation of the drawings]

[0012] The rope coupling mechanism and elevator according to the embodiment will be described below with reference to Figures 1 to 7. Note that common components in each figure are denoted by the same reference numerals.

[0013] 1. First embodiment 1-1. Elevator configuration example First, the configuration of the elevator according to the first embodiment (hereinafter referred to as "this example") will be described with reference to Figure 1. Figure 1 is a schematic diagram showing an example of an elevator configuration.

[0014] As shown in Figure 1, the elevator 100 in this example is installed in a hoistway 100 formed within a building structure. As shown in Fig. 1, the elevator 100 in this example is a so-called 1:1 roping elevator. The elevator 100 is equipped with a car 2, which is an example of a lifting body for carrying people and luggage, a main rope 3, a counterweight 4, and a hoist 5. The elevator 100 also is equipped with an emergency stop device 10 and a speed governor 13.

[0015] A hoisting machine 5 is installed in a machine room 102 located at the top of the elevator shaft 100. The main rope 3 is wound around the sheave of the hoisting machine 5. A deflector wheel 6 on which the main rope 3 is mounted is also provided near the hoisting machine 5.

[0016] The upper part of the elevator car 2 is connected to one end of the main rope 3, and the upper part of the counterweight 4 is connected to the other end of the main rope 3. When the hoisting machine 5 is driven, the elevator car 2 and the counterweight 4 move up and down in the elevator shaft. Hereinafter, the direction in which the elevator car 2 and the counterweight 4 move up and down will be referred to as the vertical direction.

[0017] The elevator car 2 is slidably supported on two guide rails 7, 7 via a guide device. Similarly, the counterweight 4 is slidably supported on the counterweight-side guide rail 8 via a guide device. The guide rails 7 and the counterweight-side guide rail 8 extend vertically within the elevator shaft 100.

[0018] Furthermore, two emergency stop devices 10 are provided at the bottom of the elevator car 2 to stop its upward and downward movement in an emergency. The emergency stop devices 10 are positioned at the bottom of the elevator car 2, facing the guide rail 7.

[0019] The speed governor 13 has an upper pulley 12 and a lower pulley 14. The upper pulley 12 is installed in a machine room 102. The upper pulley 12 is provided with a speed detection mechanism (not shown). The lower pulley 14 is installed in a pit 101, which is the lower part of the elevator shaft 100. The lower pulley 14 is also arranged below the upper pulley 12 in the vertical direction.

[0020] The governor rope 15 is wound around the upper pulley 12 and the lower pulley 14. A tension weight is attached to the lower pulley 14. Therefore, the lower pulley 14 is subjected to a predetermined load in the vertical direction downward by the tension weight. A predetermined tension is then applied to the governor rope 15 wound around the lower pulley 14 via the lower pulley 14.

[0021] The governor rope 15 is formed into a so-called endless rope by connecting both of its axial ends with a rope connecting mechanism 20. This rope connecting mechanism 20 is connected to an emergency stop device 10 installed on the elevator car 2 via a connecting lever 21. The governor rope 15 then circulates between the upper pulley 12 and the lower pulley 14 in accordance with the raising and lowering movement of the elevator car 2. The upper pulley 12 then detects the raising and lowering speed of the elevator car 2 from the circulating speed of the governor rope 15.

[0022] 1-2. Example of a Rope Connection Mechanism Configuration Next, the configuration of the rope connection mechanism 20 will be described with reference to Figure 2. Figure 2 is a front view showing the rope connection mechanism 20.

[0023] As shown in Figure 2, the rope coupling mechanism 20 includes a rotating support part 22, a coupling part 23, a cylindrical part 24, a rotating shaft 25, a rotating body 26, a bearing part 27, and fixing bolts 28 and fixing nuts 29 indicating a rotation restricting member. The rotating support part 22 is located at the lower end in the vertical direction, and the coupling part 23 is located at the upper end in the vertical direction. The coupling part 23 is connected to the coupling lever 21 by a pivot shaft 23a. The coupling lever 21 rotates around the pivot shaft 23a. Furthermore, one end 15a of the governor rope 15 is connected to the coupling part 23. The other end 15b of the governor rope 15 is connected to the rotating shaft 25.

[0024] The rotation support portion 22 is formed in a substantially cylindrical shape. An insertion hole 22a is formed in the axial center of the rotation support portion 22. The insertion hole 22a penetrates the rotation support portion 22 from one end to the other end in the axial direction. A rotation shaft 25 is inserted into this insertion hole 22a.

[0025] The other end 15b of the governor rope 15 is connected to a portion of the rotating shaft 25 that is exposed downward in the vertical direction from the rotation support part 22. A rotating body 26 is provided on the opposite side of the end of the rotating shaft 25 to the end to which the other end 15b of the governor rope 15 is connected. The rotating body 26 is inserted into a cylindrical hole 24b of a cylindrical part 24, which will be described later.

[0026] A cylindrical portion 24 is formed at one axial end of the rotation support portion 22. The cylindrical portion 24 is formed in a substantially cylindrical shape. A hollow cylindrical hole 24b is formed in the cylindrical portion 24. The rotation support portion 22 is fixed to the other axial end of the cylindrical portion 24, and the connecting portion 23 is fixed to one axial end of the cylindrical portion 24. A fixing hole 24a is formed in a side surface portion of the cylindrical portion 24 that is perpendicular to the axial direction. The fixing hole 24a communicates with the cylindrical hole 24b. Two fixing holes 24a are formed in the side surface portion of the cylindrical portion 24, with the cylindrical hole 24b of the cylindrical portion 24 sandwiched between them. The threaded portions of fixing bolts 28 are inserted into these fixing holes 24a.

[0027] A bearing 27 is disposed on the inner wall surface of the cylindrical hole 24b of the cylindrical portion 24 on the side of the rotation support portion 22. A thrust bearing is used as the bearing 27. The bearing 27 rotatably supports a rotor 26, which will be described later.

[0028] The rotor 26 is formed at one axial end of the rotary shaft 25. The rotor 26 is formed in a cylindrical shape. The rotor 26 is housed in the cylindrical hole 24b of the cylindrical portion 24. The diameter of the rotor 26 is larger than the opening diameter of the insertion hole 22a provided in the rotation support portion 22. This prevents the rotor 26 from falling out of the insertion hole 22a of the rotation support portion 22. The rotor 26 also has a rotation restriction hole 26a formed therein that penetrates in a direction perpendicular to the axial direction. The threaded portion of a fixing bolt 28 is inserted into the rotation restriction hole 26a.

[0029] Fixing bolt 28, which represents a rotation restricting member, has its threaded portion inserted into fixing hole 24a and rotation restricting hole 26a of tubular portion 24. Fixing bolt 28 is then fixed to tubular portion 24 via fixing nut 29. Fixing bolt 28 penetrates rotating body 26 in a direction perpendicular to its axial direction, thereby preventing rotating body 26 and rotating shaft 25 from rotating against the user's intention.

[0030] In this example, the fixing bolt 28 and the fixing nut 29 are used as the rotation restricting member, but the present invention is not limited to this. As the rotation restricting member, for example, a fixing pin inserted into the rotation restricting hole 26a and the fixing hole 24a, or various other members can be used as long as they can releasably restrict the rotation of the rotor 26 around the central axis of the governor rope 15.

[0031] 1-3. Adjustment of the governor rope Next, the adjustment work for the length of the governor rope 15 will be described with reference to Figures 3 to 5. Figure 3 is a front view showing a state in which the rope connection mechanism 20 is unlocked. Figure 4 is a diagram showing the adjustment operation for the governor rope 15 using the rope connection mechanism 20. Figure 5 is an explanatory diagram showing a state in which the governor rope is stretched.

[0032] First, as shown in Figure 5, the governor rope 15 is twisted at a predetermined strand pitch (twist length) 15c. Then, as elongation occurs due to aging or other factors, the spacing of the strand pitch 15c widens. Furthermore, as the elongation of the governor rope 15 progresses, there will be sections with long and short strand pitch 15c spacing. Then, after the sections with short strand pitch 15c pass through the upper pulley 12 and lower pulley 14, the tension on the governor rope 15 releases the tension, causing the strand pitch 15c to lengthen. When the strand pitch 15c lengthens, an abnormal noise is generated. Therefore, it is necessary to periodically adjust the strand pitch 15c of the governor rope 15 and adjust the length of the governor rope 15.

[0033] During the adjustment process, first, the elevator car 1 is moved to the top floor of the elevator shaft 100. This causes the other end 15b of the governor rope 15 to hang down along the elevator shaft 100. Then, as shown in Figure 3, the fixing nut 29 is removed from the fixing bolt 28. The fixing bolt 28 is then pulled out from the rotation restricting hole 26a of the rotating body 26 and the fixing hole 24a of the cylindrical part 24. As a result, the rotating body 26 and the rotating shaft 25 connected to this rotating body 26 can rotate around the central axis by the bearing part 27.

[0034] Next, as shown in Figure 4, the operator rotates the rotating shaft 25 in a direction that shortens the strand pitch 15c of the governor rope 15. By shortening the strand pitch 15c of the governor rope 15, the length of the governor rope 15 can be adjusted.

[0035] Next, the worker measures the strand pitch 15c of the governor rope 15 and confirms whether the strand pitch 15c is a regular dimension. After confirming that the strand pitch 15c is a regular dimension, the worker inserts the threaded portion of the fixing bolt 28 into the fixing hole 24a of the tubular portion 24 and the rotation restricting hole 26a of the rotating body 26. Then, the worker attaches a fixing nut 29 to the fixing bolt 28 to secure the fixing bolt 28 to the tubular portion 24 and the rotating body 26. This restricts the rotation of the rotating body 26 and the rotating shaft 25. As a result, the rotating body 26 and the rotating shaft 25 can be prevented from rotating against the user's intention, and the governor rope 15 connected to the rotating shaft 25 can be prevented from rotating.

[0036] In this way, according to the elevator 100 having the rope connection mechanism 20 of this example, the governor rope 15 can be prevented from rotating around the central axis under normal conditions, and the length of the governor rope 15 can be easily adjusted during adjustment work.

[0037] Here, the car 1 is moved to the top floor, and the other end 15b of the governor rope 15 is extended along the elevator shaft 100. As a result, the rotating body 26 and the rotating shaft 25 can be easily rotated, and the length of the governor rope 15 can be easily adjusted.

[0038] 2. Second Embodiment Example Next, a rope connecting mechanism according to a second embodiment will be described with reference to FIG. FIG. 6 is a front view showing the rope connecting mechanism according to the second embodiment.

[0039] The rope connection mechanism 30 according to the second embodiment differs from the rope connection mechanism 20 according to the first embodiment in the position of the rotation mechanism. Therefore, parts common to the rope connection mechanism 20 according to the first embodiment are given the same reference numerals and redundant explanations will be omitted.

[0040] As shown in Figure 6, the rope connection mechanism 30 has a rotation support part 32, a connecting part 33, a cylindrical part 34, a rotation shaft 35, a rotating body 36, a bearing part 37, and a fixing bolt 38 and a fixing nut 39 that represent rotation restricting members. The rotation support part 32 is disposed at the upper end in the vertical direction, and the connecting part 33 is disposed at the lower end in the vertical direction. The connecting part 33 is connected to the connecting lever 21 via a rotating shaft 33a. Furthermore, the other end 15b of the governor rope 15 is connected to the connecting part 33.

[0041] A rotating shaft 35 is inserted into the insertion hole 32a of the rotation support part 32. One end 15a of the governor rope 15 is connected to a portion of the rotating shaft 35 that is exposed upward from the rotation support part 32 in the vertical direction. A rotating body 36 is provided on the opposite side of the end of the rotating shaft 35 to the end to which the one end 15a of the governor rope 15 is connected. The rotating body 36 is inserted into the cylindrical hole 34b of the cylindrical part 34.

[0042] A cylindrical portion 34 is formed at the other axial end of the rotation support portion 32. That is, the rotation support portion 32 is fixed to one axial end of the cylindrical portion 34, and the connecting portion 33 is fixed to the other axial end of the cylindrical portion 34. A fixing hole 34a is formed in a side surface portion of the cylindrical portion 34 that is perpendicular to the axial direction. A threaded portion of a fixing bolt 38 is inserted into this fixing hole 34a.

[0043] A bearing 37 is disposed on the inner wall surface of the cylindrical hole 34b of the cylindrical portion 34 on the side of the rotation support portion 32. The bearing 37 rotatably supports the rotating body 36. The rotating body 36 is formed at the other axial end of the rotating shaft 35. The rotating body 36 is housed in the cylindrical hole 34b of the cylindrical portion 34. The rotating body 36 is also formed with a rotation restriction hole 36a that penetrates in a direction perpendicular to the axial direction. The threaded portion of a fixing bolt 38 is inserted into the rotation restriction hole 36a.

[0044] The fixing bolt 38, which indicates the rotation restricting member, has its threaded portion inserted into the fixing hole 34a and the rotation restricting hole 36a of the cylindrical portion 34. The fixing bolt 38 is then fixed to the cylindrical portion 34 via a fixing nut 39. By having the fixing bolt 38 pass through the rotating body 36 in a direction perpendicular to its axial direction, the rotating body 36 and the rotating shaft 35 can be prevented from rotating against the user's intention.

[0045] In the first embodiment, the rope coupling mechanism 20 rotates on its lower side in the vertical direction, whereas in the second embodiment, the rope coupling mechanism 30 rotates on its upper side in the vertical direction. Therefore, when adjusting the governor rope 15 in the rope coupling mechanism 30 of the second embodiment, the elevator car 1 is moved to the lowest floor of the elevator shaft 100. As a result, one end 15a of the governor rope 15 extends along the elevator shaft 100. Consequently, the rotational movement of the rotating body 36 and the rotating shaft 35 becomes easier, and the length of the governor rope 15 can be easily adjusted.

[0046] Other configurations are the same as those of the rope connection mechanism 20 according to the first embodiment described above, and therefore a description thereof will be omitted. The rope connection mechanism 30 according to this second embodiment can also achieve the same actions and effects as the rope connection mechanism 30 according to the first embodiment described above.

[0047] 3. Third embodiment Next, a rope connecting mechanism according to a third embodiment will be described with reference to FIG. FIG. 7 is a front view showing the rope connecting mechanism according to the third embodiment.

[0048] The difference between the rope coupling mechanism 40 according to this third embodiment and the rope coupling mechanism 20 according to the first embodiment is that the rotation mechanism is provided on both the vertical and horizontal sides. Therefore, the same reference numerals are used for parts common to the rope coupling mechanism 20 according to the first embodiment, and redundant explanations are omitted.

[0049] The rope connecting mechanism 40 includes a first rotation support section 42, a connecting section 43, a first cylindrical section 44, a first rotating shaft 45, a first rotating body 46, a first bearing section 47, and a first fixing bolt 48 and a first fixing nut 49 indicating a first rotation restricting member. The rope connecting mechanism 40 also includes a second rotation support section 52, a second cylindrical section 54, a second rotating shaft 55, a second rotating body 56, a second bearing section 57, and a second fixing bolt 58 and a second fixing nut 59 indicating a second rotation restricting member.

[0050] The connecting portion 43 is located in the middle of the vertical direction. The connecting lever 21 is connected to the connecting portion 43 via the pivot shaft 43a. Below the connecting portion 43 in the vertical direction, the first rotation support portion 42, the first cylindrical portion 44, the first rotation shaft 45, the first rotating body 46, the first bearing portion 47, the first fixing bolt 48, and the first fixing nut 49 are arranged. The configuration of the first rotation support portion 42, the first cylindrical portion 44, the first rotation shaft 45, the first rotating body 46, the first bearing portion 47, the first fixing bolt 48, and the first fixing nut 49 is the same as that of the rotation support portion 22, the cylindrical portion 24, the rotation shaft 25, the rotating body 26, the bearing portion 27, the fixing bolt 28, and the fixing nut 29 in the first embodiment example. Therefore, their description is omitted.

[0051] Furthermore, a second rotation support portion 52, a second cylindrical portion 54, a second rotating shaft 55, a second rotating body 56, a second bearing portion 57, a second fixing bolt 58, and a second fixing nut 59 are arranged on the upper side of the connecting portion 43 in the vertical direction. The configuration of the second rotation support portion 52, the second cylindrical portion 54, the second rotating shaft 55, the second rotating body 56, the second bearing portion 57, the second fixing bolt 58, and the second fixing nut 59 is the same as that of the rotation support portion 32, the cylindrical portion 34, the rotating shaft 35, the rotating body 36, the bearing portion 37, the fixing bolt 38, and the fixing nut 39 in the second embodiment example. Therefore, a description of these will be omitted.

[0052] According to the rope connection mechanism 40 of this third embodiment, both the upper and lower sides in the vertical direction rotate. Therefore, during adjustment work, the strand pitch 15c of the governor rope 15, that is, the length of the governor rope 15, can be adjusted without being affected by the position of the elevator car 1.

[0053] Other configurations are the same as those of the rope connection mechanism 20 according to the first embodiment described above, and therefore a description thereof will be omitted. The rope connection mechanism 40 according to this third embodiment can also achieve the same actions and effects as the rope connection mechanism 20 according to the first embodiment described above.

[0054] The present invention is not limited to the embodiments described above and shown in the drawings, and various modifications can be made without departing from the spirit of the invention as set forth in the claims.

[0055] In the above-described embodiment, an example of applying a 1:1 roping elevator as shown in Fig. 1 has been described as an elevator configuration, but the present invention is not limited to this. As the elevator configuration, a 2:1 roping elevator or various other elevators can also be applied.

[0056] Furthermore, although the governor rope 15 is used as the rope to which the rope connection mechanism is attached, the present invention is not limited to this. Various other ropes, such as main ropes and compensating ropes, can be used as the rope to which the rope connection mechanism is attached. When the main rope or compensating rope is used as the rope to which the rope connection mechanism is attached, the rope connection mechanism is provided at the end of the main rope or compensating rope that is fixed to a thimble rod that connects to the car or counterweight.

[0057] In this specification, the words "parallel" and "orthogonal" are used, but these do not mean only "parallel" and "orthogonal" in the strict sense, but also include "parallel" and "orthogonal" and may also mean a "substantially parallel" or "substantially orthogonal" state within a range in which the functions can be exerted.
