[0010] An embodiment of the present invention will be described below with reference to the drawings.

[0011] A construction elevator will be described using Figure 1. Figure 1 is a schematic diagram of a rope gripping device 8 according to an embodiment of the present invention used as part of a main rope fixing device 7 of a construction elevator.

[0012] The construction elevator comprises a main rope 1, a temporary machine room 6, a car 3, a counterweight 5, and a lifting machine 11. The temporary machine room 6 has a car-side rope end 2, a hoisting machine 4, a main rope fixing device 7, a diverting pulley 9, and a main rope drum 10. A rope gripping device 8 is installed in the main rope fixing device 7.

[0013] During construction operations, the main rope 1 starts at the cage-side rope end 2, passes through the cage 3, hoist 4, and counterweight 5, and is secured by a main rope securing device 7 installed in a temporary machine room 6. The excess length of the main rope 1 passes through a diverting pulley 9 and is wound around a main rope drum 10. At this time, the rope gripping device 8, which is part of the main rope securing device 7, plays the role of the rope end on the counterweight 5 side, and therefore must grip the secured main rope 1 without slipping.

[0014] During the lifting of the temporary machine room 6, the temporary machine room 6 is moved upward by the crane 11, extending the ascent and descent stroke of the construction elevator. Therefore, the rope holding device 8 must release its grip on the main rope 1 as appropriate and let out the main rope 1 wound around the main rope drum 10 downward. At this time, the rope holding device 8 must ensure an appropriate clearance for the main rope 1 to pass between a pair of clamping plates 14A, 14B (see Figure 2) that hold the main rope 1, and let out the main rope 1 smoothly. In addition, because the rope holding device 8 is installed in the temporary machine room 6, the working space for gripping and releasing the main rope 1 is limited.

[0015] The clamping plates 14A and 14B are members that have the function of holding the main rope 1 by clamping and pressing the main rope 1. Because the clamping plates 14A and 14B have the function of clamping and holding the main rope 1, they will be called "main rope clamping plates" or simply "clamping plates."

[0016] The rope gripping device 8 will be described with reference to Figures 2 and 3. Figure 2 is a diagram showing the overall configuration of the rope gripping device 8 shown in Figure 1, and is a diagram (side view) of the rope gripping device 8 as seen from the horizontal direction. Figure 3 is a diagram (top view) of the rope gripping device 8 shown in Figure 2 as seen from above. Figures 2 and 3 show the rope gripping device 8 during lifting of a temporary machine room, and show the state in which the grip on the main rope 1 has been released, i.e., the released state of the main rope 1. Note that in Figure 2, the main rope 1 is shown semi-transparent.

[0017] Simply put, the rope holding device 8 has the function of holding the main rope 1 by clamping it between a pair of opposing members. Specifically, it is equipped with a fixed plate 12, a movable plate 13, clamping plates 14A and 14B, a fastening plate 15, a guide (guide member) 16, a fastening bolt 17, a pressing bolt 18, a nut 19, and a release bolt 26. The release bolt 26 is a part used during release, and will be explained later using Figure 4.

[0018] The fixing plate 12 has fixing screw holes 20 and is fixed to the inside of the temporary machine room 6 using bolts or the like (not shown). The rope gripping device 8 is attached to the inside of the temporary machine room 6 by fixing the fixing plate 12 to the inside of the temporary machine room 6.

[0019] The movable plate 13 has a guide insertion hole 21, and the guide 16 is provided to pass through the guide insertion hole 21, so that the movable plate 13 can move along the guide 16. Specifically, in a state without the main ropes 1, the movable plate 13 can move along the axial direction (guiding direction) 16x of the guide 16 between the fixed plate 12 and the fastening plate 15 from the state shown in FIG. 2, i.e., a state in which the mutually opposing surfaces 13b, 15a of the movable plate 13 and the fastening plate 15 are in contact, until the mutually opposing surfaces 14Aa, 14Ba of the pair of clamping plates 14A, 14B abut against each other. In addition, the movable plate 13 has a threaded hole (second threaded hole) 22 into which a release bolt 26 is threaded, and the threaded hole 22 is used to pull up the movable plate 13 by the release bolt 26 when the main ropes 1 are released.

[0020] The clamping plate (second clamping plate) 14A is fixed to the movable plate 13 by fastening bolts 32 into screw holes 31 formed in the movable plate 13. The clamping plate (first clamping plate) 14B is fixed to the fixed plate 12 by fastening bolts 34 into screw holes 33 formed in the fixed plate 12. The clamping plate 14A is attached to the end face 13a side of the movable plate 13 opposite the end face 13b on the fastening plate 15 side (the main rope 1 side). The clamping plate 14B is attached to the end face 12a side of the fixed plate 12 on the fastening plate 15 and movable plate 13 side.

[0021] Clamping plate 14A is integrally assembled to movable plate 13, and clamping plate 14B is integrally assembled to fixed plate 12. For this reason, clamping plate (first clamping plate) 14B and fixed plate 12 are regarded as an integral member and are called the "first clamping member." Clamping plate (second clamping plate) 14A and movable plate 13 are regarded as an integral member and are called the "second clamping member."

[0022] The first clamping members 14B, 12 include a fixed plate 12 to which a fastening plate 15 is fixed by fastening bolts 17, and a first clamping plate 14B fixed to the fixed plate 12. The second clamping members 14A, 13 include a movable plate 13 in which a guide insertion hole 21 is formed, and a second clamping plate 14A fixed to the movable plate 13. The first clamping plate 14B and the second clamping plate 14A have grooves 25A, 25B that come into contact with the main rope (rope) 1 and clamp the main rope 1.

[0023] The second clamping members 14A and 13 are arranged to be movable between the first clamping members 14B and 12 and a fastening plate 15, which will be described later.

[0024] The clamping plates 14A and 14B have grooves 25A and 25B for gripping the rope. Groove 25A is formed on the end face 14Aa of the clamping plate 14A opposite the movable plate 13 side. Groove 25A has a V-shaped cross section and includes a deepest portion 25Aa where the groove is deepest, and side portions 25Ab formed on both sides of deepest portion 25Aa so as to be inclined relative to the groove depth direction. Groove 25B is formed on the end face 14Ba of the clamping plate 14B opposite the fixed plate 12 side. Groove 25B has a V-shaped cross section and includes a deepest portion 25Ba where the groove is deepest, and side portions 25Bb formed on both sides of deepest portion 25Ba so as to be inclined relative to the groove depth direction. When the main rope 1 is clamped by the clamping plates 14A, 14B in the groove 25 of the clamping plates 14A, 14B, it comes into contact with the side surface portion 25Ab of the groove 25A and the side surface portion 25Bb of the groove 25B, and receives a clamping force from the side surface portions 25Ab, 25Bb.

[0025] The fastening plate 15 is fastened to the fixed plate 12 by fastening bolts 17 passed through guides 16. The distance L0 between the fastening plate 15 and the fixed plate 12 is determined by the length of the guide 16, and the relative position of the fastening plate 15 to the first clamping members 14B, 12 is fixed. The distance L0 between the fastening plate 15 and the fixed plate 12 can be adjusted by changing the length of the guide 16. The guide (guide member) 16 constitutes a positioning mechanism that positions the fastening plate 15 relative to the first clamping members 14B, 12.

[0026] Fastening bolt through-holes 30 are provided in the fastening plate 15 to allow the fastening bolts 17 to pass through. When the fastening plate 15 is fastened to the fixing plate 12 by the fastening bolts 17, the position of the fastening plate 15 is fixed by the guide 16 so that the distance L0 between the fastening plate 15 and the fixing plate 12 is maintained at a constant value.

[0027] The fastening plate 15 has a press bolt threaded hole (first threaded hole) 23, and the press bolt 18 can be tightened or screwed in by threading the press bolt 18 into the press bolt threaded hole 23. The fastening plate 15 has a release bolt through-hole 24, and is configured so that a release bolt 26 can be inserted therethrough.

[0028] 2, when the main rope 1 is not gripped (released state), the tip 18a of the press bolt 18 does not protrude from the end face 15a of the fastening plate 15 on the movable plate 13 side toward the movable plate 13. In other words, the tip 18a of the press bolt 18 does not abut against the end face 13b of the movable plate 13. This is because the clamping plate 14A is pushed out toward the clamping plate 14B side so that the main rope 1 is not clamped or pressed between the clamping plates 14A and 14B when the main rope 1 is released; however, as long as the state in which the main rope 1 is not clamped or pressed can be maintained, the tip 18a of the press bolt 18 may protrude from the end face 15a of the fastening plate 15 toward the movable plate 13 and abut against the end face 13b of the movable plate 13.

[0029] 2, in the released state of the main rope 1, it is preferable to keep the tip 18a of the pressing bolt 18 out of contact with the end face 13b of the movable plate 13 and to retract the movable plate 13 toward the fastening plate 15 with the release bolt 26 so that the end face 13b of the movable plate 13 contacts the end face 15a of the fastening plate 15. In this case, the distance L2 between the end face 13b of the movable plate 13 and the end face 15a of the fastening plate 15 is zero (L2=0). This makes it possible to reliably prevent the main ropes 1 from sliding against the clamping plates 14A when the main ropes 1 are in a released state.

[0030] 2 and 3 show the main rope 1 in a released state, where the distance between the pair of clamping plates 14A and 14B, i.e., the distance L1 between the end face 14Aa of clamping plate 14A and the end face 14Ba of clamping plate 14B, has expanded to La (L1 = La). In this state, the space between the two grooves 25A and 25B has expanded, and the main rope 1 is released from the clamping by the pair of clamping plates 14A and 14B, and is no longer gripped by the clamping plates 14A and 14B.

[0031] In order to prevent the main rope 1 from slipping out of the grooves 25A and 25B of the clamping plates 14A and 14B, it is preferable to set La smaller than the diameter φ1 of the main rope 1 (La<φ1).

[0032] The gripping state of the main rope 1 will be described with reference to Figures 4 and 5. Figure 4 is a diagram (side view) showing the rope gripping state of the rope gripping device 8 shown in Figure 2. Figure 5 is a diagram (top view) of the rope gripping device 8 shown in Figure 4 as seen from above. Note that in Figure 4, the main rope 1 is shown semi-transparently.

[0033] The fastening plate 15 is fixed at a fixed position L0 from the fixed plate 12 by fastening bolts 17 and guides 16, and the movable plate 13 moves along the guides 16 by tightening the pressing bolts 18. In this embodiment, guides (guide members) 16 are provided to guide the movement of the second clamping members 14A, 13. The second clamping members 14A, 13 have guide insertion holes 21, and the guides 16 are provided to pass through the guide insertion holes 21, allowing the second clamping members 14A, 13 to move along the guides 16.

[0034] When the main rope 1 is in the released state (the state shown in FIGS. 2 and 3), by screwing the pressing bolt 18 into the screw hole 23 for the pressing bolt of the fastening plate 15, the tip 18a of the pressing bolt 18 presses the movable plate 13. That is, in this embodiment, the pressing bolt 18 is screwed into the screw hole (first screw hole) 23 for the pressing bolt from the side of the fastening plate 15 opposite to the side where the second clamping members 14A and 13 are arranged, and presses the second clamping members 14A and 13 toward the first clamping members 14B and 12. Thereby, the axial force of the pressing bolt 18 is transmitted to the clamping plate 14A via the movable plate 13, and the clamping plate 14A is pressed toward the clamping plate 14B. As a result, the main rope 1 receives a pressing force from the clamping plate 14A and the clamping plate 14B and is gripped by the clamping plate 14A and the clamping plate 14B.

[0035] FIGS. 4 and 5 show the gripping state of the main rope 1. In the gripping state of the main rope 1, the distance between the pair of clamping plates 14A and 14B, that is, the distance L1 between the end face 14Aa of the clamping plate 14A and the end face 14Ba of the clamping plate 14B becomes Lb (L1 = Lb). The magnitude Lb of the distance L1 at this time is smaller than the magnitude La of the distance L1 in the released state of the main rope 1 (Lb < La). Also, the distance L2 between the end face 13b of the movable plate 13 and the end face 15a of the fastening plate 1 is greater than zero and becomes δ (L2 = δ, δ > 0).

[0036] After gripping the main rope 1 by pressing the pressing bolt 18, fix it with the nut 19 so that the pressing bolt 18 does not loosen. That is, tighten the nut 19 in a state separated from the end face 15b of the fastening plate 15 so as to contact the end face 15b This embodiment adopts a pressing method in which the clamping plate 14A is pressed against the main rope 1 using the pressing bolt 18 and the main rope 1 is gripped together with the clamping plate 14B.

[0037] In this embodiment, the nuts 19 and press bolts 18, and the press bolt threaded holes (first threaded holes) 23 into which the press bolts 18 are fastened, are arranged on the same side with respect to the second clamping members 14A, 13 and the first clamping members 14B, 12. Furthermore, the fastening plate 15 in which the press bolt threaded holes 23 are formed does not need to be prevented from co-rotating when the press bolts 18 are fastened.

[0038] In this case, the press bolt 18 has a nut 19 for preventing the press bolt 18 from loosening, on the side of the fastening plate 15 opposite to the side on which the second holding members 14A and 13 are arranged.

[0039] This allows the operation of the press bolt 18 and the locking nut 19 to be performed from one direction when gripping the main rope 1. In this case, the operation of the press bolt 18 and the operation of the nut 19 are performed from one end face 15b side of the fastening plate 15.

[0040] 2 to 5, an operation (releasing operation) for returning the main rope 1 from the gripped state (the state shown in FIGS. 4 and 5) to the released state (the state shown in FIGS. 2 and 3) will be described.

[0041] The release operation requires the operation of releasing the locking mechanism of the press bolt 18 and the operation of pulling up the press bolt 18. The operation of releasing the locking mechanism of the press bolt 18 is performed by loosening the nut 19. The operation of pulling up the press bolt 18 is performed by pulling the press bolt 18 from the end face 15a toward the end face 15b of the fastening plate 15 so as to move the tip portion 18a of the press bolt 18 away from the end face 13b of the movable plate 13.

[0042] Next, a release bolt 26 is passed through a release bolt through-hole 24 formed in the fastening plate 15 (see FIG. 2), and the release bolt 26 is tightened into a release bolt threaded hole (second threaded hole) 22 formed in the movable plate 13. The release bolt 26 is a member for pulling the second clamping members 14A, 13, which grip the main rope 1 together with the first clamping members 14B, 12, away from the first clamping members 14B, 12. With the release bolt 26 tightened into the release bolt threaded hole 22, the movable plate 13 can be pulled up to the fastening plate 15. In other words, by tightening the release bolt 26 into the release bolt threaded hole (second threaded hole) 22, the second clamping members 14A, 13 move in a direction away from the first clamping members 14B, 12.

[0043] When the movable plate 13 is pulled up to its maximum extent, the distance L2 between the end face 13b of the movable plate 13 and the end face 15a of the fastening plate 15 is zero (L2 = 0), as shown in Figures 2 and 3. At this time, the movable plate 13 has moved by δ from the state in which it is gripping the main rope 1, so the distance Lb between the pair of clamping plates 14A, 14B in the released state of the main rope 1 becomes La minus δ (Lb = La - δ).

[0044] The movable plate 13 has guide insertion holes 21 (see Figures 2 and 4) through which the guides 16 pass, and is capable of moving along the guides 16, allowing it to move parallel to the main rope 1. As a result, when the movable plate 13 is pulled up, a certain distance La can be provided from the upper end to the lower end between the pair of opposing clamping plates 14A, 14B. For this reason, by having the guides 16 and the release bolt 26, the rope gripping device 8 can ensure an appropriate clearance for the passage of the main rope 1 between the pair of clamping plates 14A, 14B when releasing the main rope 1 during the lifting of the temporary machine room 6, allowing the main rope 1 to be let out smoothly.

[0045] The operation of returning the main rope 1 from the gripped state to the released state includes the operation of the nut 19 and the pressing bolt 18, and the operation of the release bolt 26. These operations can be performed from one direction. In other words, these operations can be performed from one end face 15b side of the fastening plate 15.

[0046] In this embodiment, the nuts 19 and press bolts 18, the press bolt threaded holes (first threaded holes) 23 into which the press bolts 18 are fastened, and the release bolts 26 are arranged on the same side with respect to the second clamping members 14A, 13 and the first clamping members 14B, 12. Furthermore, the fastening plate 15 in which the press bolt threaded holes 23 are formed does not need to be prevented from co-rotating when the press bolts 18 are loosened.

[0047] The fastening plate 15 will be described with reference to Fig. 6. Fig. 6 is a cross-sectional view of the fastening plate 15 as seen from the direction shown in Fig. 2.

[0048] The fastening plate 15 has a press bolt threaded hole 23 on the side of the end face 15b, and a bolt relief hole 28 on the side of the end face 15a (movable plate 13). The diameter C of the bolt relief hole 28 is larger than the diameter B of the press bolt threaded hole. That is, the fastening plate 15 has a bolt relief hole (relief hole) 28, through which the press bolt 18 is inserted, provided on the side of the second clamping members 14A, 13 with respect to the press bolt threaded hole (first threaded hole) 23. The diameter C of the bolt relief hole 28 is larger than the diameter B of the press bolt threaded hole (first threaded hole) 23.

[0049] Pressing against the movable plate 13 can cause slight deformation in the tip 18a of the press bolt 18. By providing a bolt relief hole 28 in the fastening plate 15, the tip 18a of the press bolt 18 is prevented from getting caught on the end surface 15a of the fastening plate 15 when the press bolt 18 is pulled up to the inside of the fastening plate 15. This makes it possible to repeatedly grip and release the main rope 1. If the diameter C of the bolt relief hole 28 is 2 mm or more larger than the diameter B of the press bolt threaded hole 23, it is possible to suppress or prevent slight deformation of the tip 18a of the press bolt 18 from getting caught on the end surface 15a of the fastening plate 15.

[0050] The above-mentioned embodiment has been described as a rope gripping device used in a construction elevator, but it can also be used as a rope gripping device for gripping ropes in other devices other than elevators.

[0051] The present invention is not limited to the above-described embodiments, but includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the configurations. Furthermore, it is possible to add, delete, or replace part of the configuration of the embodiments with other configurations. [Explanation of symbols]
