The rope braking device 8 brakes the main ropes 9 between the traction sheave 7 and the guide sheave 4.
The car 103 is connected to a counterweight 104 via a main rope 9. The elevator apparatus 101 configured as described above drives the main rope 9 by rotating the traction sheave 7 of the hoisting machine 5, and lifts and lowers the car 103 and the counterweight 104 in the elevator shaft 102 in opposition to each other.
In fig. 1, only the lowermost floor 106 and the uppermost floor 107 are schematically shown as floors of the building structure. However, the building structure may have 3 or more floors. Further, a landing door 109 is provided on each floor. When the car 103 is stopped, the landing door 109 faces a car door 110 provided in the car 103. The landing door 109 is opened and closed together with the car door 110.
As shown in fig. 2, a base 1 is disposed in the machine room 120. The base 1 is fixed to a beam member, not shown, of a building structure. A hoisting machine base 2 and an attachment base 3 are fixed to the upper portion of the base 1, and a guide wheel 4 is rotatably supported to the lower portion of the base 1. A hoisting machine 5 and a brake device 6 are mounted on the hoisting machine base 2. A traction sheave 7 is rotatably supported by the hoisting machine base 2.
On the other hand, a cable brake device 8 is mounted on the mounting base 3. When an abnormality or a failure occurs in the brake device 6 and the elevator control device (not shown) provided in the hoisting machine 5, the rope brake device 8 sandwiches and restricts the main rope 9 positioned between the guide sheave 4 and the traction sheave 7. Thereby, the rope brake device 8 brakes the main rope 9 and the car 103 (counterweight 104).
[ Structure of Cable brake device ]
Next, the structure of the cable brake device 8 will be described with reference to fig. 3 and 4. Fig. 3 is a side view showing the cable brake device. Fig. 4 is a top view of the cable brake device.
The cable brake device 8 has a cable brake base 11, and a brake shoe member 10 rotatably supported on the cable brake base 11. The cable brake base 11 is secured to the mounting base 3 by a plurality of bolts 40. That is, the cable brake base 11 is fixed to the beam member of the building structure via the mounting base 3 and the base 1. Further, the cable brake base 11 is provided with a long hole through which the bolt 40 passes. The elongated hole extends in an adjustment direction described later.
As shown in fig. 4, the cable brake base 11 is constituted by a pair of base members 11A, 11B. The pair of base members 11A and 11B are each formed in a substantially L shape by bending a plate-like member, and have a fixing portion fixed to the mounting base 3 and a support portion for supporting the brake shoe member 10.
The support portions of the pair of base members 11A and 11B face each other across the brake shoe member 10. The support portions are provided with through holes through which the rotation center shafts 16 such as bolts are inserted. The 2 rotation center axes 16 passing through the pair of base members 11A and 11B are fixed to a brake case 12, which will be described later, of the brake shoe member 10. The brake shoe member 10 can be angularly adjusted about the rotation center axis 16 by releasing the 2 rotation center axes 16 from fixing the brake case 12.
The 2 rotation center shafts 16 provided in the brake case 12 have screw holes for screwing them, which are located on the same axis. That is, the axial centers of the 2 rotation center shafts 16 are aligned in the direction in which the support portions of the pair of base members 11A, 11B face each other. Hereinafter, the direction in which the support portions of the pair of base members 11A and 11B face each other is referred to as the axial direction. The direction orthogonal to the ascending/descending direction and the axial direction is defined as an adjustment direction.
Further, an arc-shaped angle adjustment groove 17 drawn around the rotation center axis 16 is formed in the support portion of the pair of base members 11A and 11B. A shaft 18 fixed to the brake case 12 and an angle adjustment shaft 19 pass through the angle adjustment groove 17. The shaft 18 and the angle adjustment shaft 19 are, for example, bolts, and collars are attached to the outer peripheral portions of the angle adjustment shaft 19. When the brake shoe member 10 rotates about the rotation center axis 16, the shaft 18 and the angle adjustment shaft 19 move in the angle adjustment groove 17.
The brake shoe member 10 is inclined along the main cable 9, and includes a brake case 12, a fixed-side brake shoe 13 capable of gripping the main cable 9, a movable-side brake shoe 14, and a movable link 15. The fixed-side brake shoe 13 is fixed to the brake case 12, and the movable-side brake shoe 14 faces the fixed-side brake shoe 13 across the main cable 9.
The movable link 15 is attached to the brake case 12 and is connected to the movable-side brake shoe 14. A driving device (not shown) for moving the movable link 15 is disposed inside the brake case 12. When the movable link 15 is moved by the driving device, the movable-side brake shoe 14 connected to the movable link 15 moves to the fixed-side brake shoe 13 side. Thereby, the fixed-side brake shoes 13 and the movable-side brake shoes 14 grip the main cable 9 and apply a braking force to the main cable 9.
The drive device (not shown) provided in the brake case 12 includes: a spring member, and a solenoid device that normally maintains the spring member in a compressed state. The solenoid device is driven in an emergency to release the compressed state of the spring member. The spring member moves the movable link 15 when the compressed state is released. By the movement of the movable link 15, the movable-side brake shoe 14 moves to the fixed-side brake shoe 13 side, and the fixed-side brake shoe 13 and the movable-side brake shoe 14 grip the main rope 9.
On the side of the mounting base 3 opposite to the traction sheave 7 side, L-shaped support brackets 23, 24 are fixed by bolts 41. A position adjustment hook 25A is supported on the support bracket 23 so as to be movable in an adjustment direction. The support bracket 23 and the position adjustment hook 25A constitute a first adjustment block 21.
Further, a position adjustment hook 25B and an angle adjustment hook 26 are supported on the support bracket 24 so as to be movable in the adjustment direction. The support bracket 24, the position adjustment hook 25B, and the angle adjustment hook 26 constitute a second adjustment block 22. The position adjustment hook 25B and the angle adjustment hook 26 are arranged in the vertical direction (up-down direction), and the angle adjustment hook 26 is located above the position adjustment hook 25B.
Fig. 5 is a side view showing first adjusting block 21. As shown in fig. 5, support bracket 23 of first adjusting block 21 includes: a fixing portion 23a fixed to the mounting base 3, a hook fastening portion 23b fastening the position adjustment hook 25A, and a shaft fixing portion 23c fixing a guide shaft 42 described later.
The fixing portion 23a is formed in a flat plate shape having a plane orthogonal to the lifting direction, and the hook fastening portion 23b is formed in a flat plate shape having a plane orthogonal to the adjustment direction. The shaft fixing portion 23c is formed in a flat plate shape having a plane orthogonal to the axial direction. A guide shaft 42 is fixed to the shaft fixing portion 23 c. For example, a bolt can be applied as the guide shaft 42, but the cylindrical member is not limited to the bolt.
The position adjustment hook 25A includes a hook piece 25A that engages with the rotation center shaft 16 (see fig. 4), and a coupling piece 25b that is coupled to the hook piece 25A by a plurality of bolts 43. The coupling piece 25b is coupled to the hook piece 25a, and has a facing portion facing the shaft fixing portion 23c of the support bracket 23 and a bent portion 27 facing the hook fastening portion 23b of the support bracket 23.
The opposite portion of the connecting piece 25b has a guide groove (not shown) through which the guide shaft 42 passes. The guide groove extends in the adjustment direction. The movement of the position adjustment hook 25A in the lifting direction is restricted by engaging the guide shaft 42 with the guide groove. Further, the movement of the position adjustment hook 25A in the axial direction is restricted by the opposing portion of the connecting piece 25b abutting against the shaft fixing portion 23 c.
The bent portion 27 of the position adjustment hook 25A is fixed to the hook fastening portion 23b by an adjustment bolt 44. That is, a screw hole for screwing the adjustment bolt 44 is formed in the bent portion 27, and the adjustment bolt 44 is inserted through the hook fastening portion 23 b. By rotating the adjusting bolt 44, the screwing position of the adjusting bolt 44 with respect to the bent portion 27 changes, and the position adjusting hook 25A moves in the position adjusting direction.
Fig. 6 is a side view showing second adjustment block 22. As shown in fig. 6, support bracket 24 of second adjustment block 22 includes: a fixing portion 24a fixed to the mounting base 3, a hook fastening portion 24B fastening the position adjustment hook 25B and the angle adjustment hook 26, and a shaft fixing portion 24c fixing guide shafts 42 and 45 described later.
The fixing portion 24a is formed in a flat plate shape having a plane orthogonal to the lifting direction, and the hook fastening portion 24b is formed in a flat plate shape having a plane orthogonal to the adjustment direction. The shaft fixing portion 24c is formed in a flat plate shape having a plane orthogonal to the axial direction.
The guide shafts 42 and 45 are fixed to the shaft fixing portion 24 c. The guide shafts 42 and 45 are arranged in the vertical direction, and the guide shaft 45 is positioned above the guide shaft 42. Further, the guide shaft 42 is positioned on the same axis as the guide shaft 42 of the first adjusting block 21 described above. For example, bolts can be applied as the guide shafts 42 and 45, but the members are not limited to bolts as long as they are cylindrical.
The position adjustment hook 25B is formed to be plane-symmetrical to the position adjustment hook 25A of the first adjustment block 21 with a plane orthogonal to the axial direction as a plane mirror, and includes a hook piece 25A and a connection piece 25B. The connecting piece 25b has a facing portion facing the shaft fixing portion 24c of the support bracket 24 and a bent portion 27 facing the hook fastening portion 24b of the support bracket 24.
The opposite portion of the connecting piece 25b has a guide groove (not shown) through which the guide shaft 42 passes. The guide groove extends in the adjustment direction. The movement of the position adjustment hook 25B in the lifting direction is restricted by the engagement of the guide shaft 42 with the guide groove. Further, the movement of the position adjustment hook 25B in the axial direction is restricted by the facing portion of the coupling piece 25B abutting against the shaft fixing portion 24 c.
The bent portion 27 of the position adjustment hook 25B is fixed to the hook fastening portion 23B by an adjustment bolt 44. That is, a screw hole for screwing the adjustment bolt 44 is formed in the bent portion 27, and the adjustment bolt 44 is inserted through the hook fastening portion 24 b. By rotating the adjusting bolt 44, the screwing position of the adjusting bolt 44 with respect to the bent portion 27 changes, and the position adjusting hook 25B moves in the position adjusting direction.
The angle adjustment hook 26 includes a hook piece 26a engaged with the angle adjustment shaft 19, and a coupling piece 26b coupled to the hook piece 26a by a plurality of bolts 46. A plurality of elongated holes 28 through which a plurality of bolts 46 are inserted are formed in the hook piece 26 a. In addition, screw holes for screwing the plurality of bolts 46 are formed in the connecting piece 26 b. Thus, the angle adjustment hook 26 is configured to be adjustable in length in the adjustment direction, which is the longitudinal direction.
The coupling piece 26b of the angle adjustment hook 26 is coupled to the hook piece 26a, and has a facing portion facing the shaft fixing portion 24c of the support bracket 24 and a bent portion 29 facing the hook fastening portion 24b of the support bracket 24.
The opposite portion of the coupling piece 26b has a guide groove (not shown) through which the guide shaft 45 passes.
The guide groove extends in the adjustment direction. The movement of the angle adjustment hook 26 in the lifting direction is restricted by engaging the guide shaft 45 with the guide groove. Further, the movement of the angle adjustment hook 26 in the axial direction is restricted by the opposing portion of the connecting piece 26b abutting against the shaft fixing portion 24 c.
The bent portion 29 of the angle adjustment hook 26 is fixed to the hook fastening portion 24b by an adjustment bolt 47. That is, a screw hole for screwing the adjustment bolt 47 is formed in the bent portion 29, and the adjustment bolt 47 is inserted through the hook fastening portion 24 b. By rotating the adjustment bolt 47, the screwing position of the adjustment bolt 47 with respect to the bent portion 29 changes, and the angle adjustment hook 26 moves in the position adjustment direction.
[ method for adjusting position of Cable brake device ]
Next, a method of adjusting the position of the rope brake device 8 will be described. When the position of the cable brake device 8 is adjusted, the first adjustment block 21 and the second adjustment block 22 are attached to the cable brake device 8.
When the first adjustment block 21 is attached to the cable brake device 8, the support bracket 23 is first fixed to the attachment base 3 by the bolt 41. Then, in a state where the hook piece 25A of the position adjustment hook 25A is engaged with the rotation center shaft 16, the bent portion 27 of the position adjustment hook 25A is fixed to the hook fastening portion 23b of the support bracket 23 by the adjustment bolt 44. Thereby, the first adjusting block 21 is attached to the cable brake device 8.
When the second adjustment block 22 is attached to the cable brake device 8, the support bracket 24 is fixed to the attachment base 3 by the bolt 41. Then, in a state where the hook piece 25a of the position adjustment hook 25B is engaged with the rotation center shaft 16, the bent portion 27 of the position adjustment hook 25B is fixed to the hook fastening portion 24B of the support bracket 24 by the adjustment bolt 44.
In a state where the hook piece 26a of the angle adjustment hook 26 is engaged with the angle adjustment shaft 19, the bent portion 29 of the angle adjustment hook 26 is fixed to the hook fastening portion 24b of the support bracket 24 by the adjustment bolt 44. Thus, the second adjusting block 22 is attached to the cable brake device 8.
When the position of the cable brake device 8 in the adjustment direction is adjusted, the adjustment bolt 44 is rotated to move the position adjustment hooks 25A and 25B in the adjustment direction. Thereby, a thrust is applied to the rotation center shaft 16 engaged with the hook piece 26a of the position adjustment hooks 25A and 25B, and the cable brake device 8 moves in the adjustment direction.
At this time, the cable brake device 8 (the cable brake base 11 and the brake shoe member 10) can be moved in the adjustment direction by loosening the fastening of the bolt 40 that fixes the cable brake base 11 to the mounting base 3 in advance. After the position of the cable brake device 8 in the adjustment direction is determined, the bolt 40 is rotated to fix the cable brake base 11 to the mounting base 3. Thereby, the position of the rotation center axis 16 that becomes the rotation center of the brake shoe member 10 is determined.
As described above, the position adjusting hooks 25A and 25B, the support brackets 23 and 24, and the rotation center shaft 16 constitute a position adjusting device that adjusts the position of the cable brake device 8 in the adjustment direction. Further, the position of the cable brake device 8 can be easily adjusted simply by rotating the adjusting bolt 44.
When the angle of the brake shoe member 10 with respect to the cable brake base 11 is adjusted, the adjustment bolt 47 is rotated to move the angle adjustment hook 26 in the adjustment direction. Thereby, the angle adjustment shaft 19 with which the hook piece 26a of the angle adjustment hook 26 engages moves in the angle adjustment groove 17, and the brake shoe member 10 rotates about the rotation center axis 16.
For example, when the angle adjustment hook 26 is moved in a direction approaching the hook fastening portion 24b by rotating the adjustment bolt 47, the brake shoe member 10 rotates in the counterclockwise direction in fig. 3 about the rotation center axis 16. On the other hand, when the angle adjustment hook 26 is moved in a direction away from the hook fastening portion 24b, the brake shoe member 10 rotates clockwise in fig. 3 due to its own weight, and the angle adjustment shaft 19 moves in the angle adjustment groove 17 following the hook piece 26a of the angle adjustment hook 26.
Further, when the angle of the brake shoe member 10 is adjusted, the angle adjustment shaft 19 moves in the angle adjustment groove 17, and therefore the contact portion between the hook piece 26a of the angle adjustment hook 26 and the angle adjustment shaft 19 changes. As described above, since the collar is attached to the outer peripheral portion of the angle adjustment shaft 19, the packing portion of the angle adjustment shaft 19 has a cylindrical shape. As a result, even if the contact portion between the hook piece 26a and the angle adjustment shaft 19 changes, the contact area between the hook piece 26a and the angle adjustment shaft 19 can be secured, and the angle adjustment shaft 19 can be smoothly moved. Therefore, the angle of the brake shoe member 10 can be adjusted with high accuracy. Further, stress can be prevented from concentrating on a specific portion of the hook piece 26a and the angle adjustment shaft 19, and damage to the hook piece 26a and the angle adjustment shaft 19 can be suppressed.
When the rotation angle of the brake shoe member 10 is to be increased, the length of the angle adjustment hook 26 in the adjustment direction is changed by changing the position of the bolt 46 in the elongated hole 28. This can increase the amount of displacement (amount of movement) between the hook piece 26a of the angle adjustment hook 26 and the angle adjustment shaft 19, and can increase the rotation angle of the brake shoe member 10.
In addition, when the angle of the brake shoe member 10 is adjusted, the cable brake base 11 can be rotated by loosening the fastening of the rotation center shaft 16, the shaft 18, and the angle adjustment shaft 19 that fix the brake shoe member 10 to the cable brake base 11 in advance. After the angle of the cable brake device 10 is determined, the rotation center shaft 16, the shaft 18, and the angle adjustment shaft 19 are rotated to fix the brake shoe member 10 to the cable brake base 11. This determines the angle of the brake shoe member 10.
As described above, the angle adjusting hook 26, the support bracket 24, and the angle adjusting shaft 19 constitute an angle adjusting device for adjusting the angle of the cable brake device 8. Further, the angle of the brake shoe member 10 can be easily adjusted simply by rotating the adjusting bolt 47.
According to the elevator apparatus and the position adjustment method of the rope brake apparatus having the above-described configurations, the position adjustment hooks 25A and 25B and the angle adjustment hook 26 can be easily attached to the rope brake apparatus 8 only by fixing the first adjustment block 21 and the second adjustment block 22, each of which is formed by integrating the hook portion and the bracket, to the rope brake base 11. Further, since the position adjustment hooks 25A and 25B and the angle adjustment hook 26 are engaged with the rotation center shaft 16 and the angle adjustment shaft 19, it is not necessary to disassemble the cable brake device 8 or assemble the cable brake device 8 again after the adjustment blocks 21 and 22 are attached.
After the position of the cable brake device 8 is determined, the first adjustment block 21 and the second adjustment block 22 can adjust the angle of the brake shoe member 10 in this state. This reduces the burden on the operator, and allows the position adjustment (angle adjustment) of the cable brake device 8 to be performed easily. In addition, it is possible to achieve a reduction in the work time required for the position adjustment (angle adjustment) of the rope brake device 8.
That is, according to the present embodiment, it is not necessary to disassemble the other adjusting device or to assemble the other adjusting device again after each adjustment, as in the case where the position adjusting device and the angle adjusting device are independently configured, and the adjustment work can be efficiently performed with a simple configuration. Further, the burden on the operator can be reduced, and the adjustment work can be shortened.
In the present embodiment, the length of the angle adjustment hook 26 in the adjustment direction is made variable. Therefore, even when the angle of adjustment of the brake shoe member 10 is large, the angle adjustment hook 26 can be changed to a length corresponding to the angle to be adjusted, and thereafter the angle adjustment of the angle adjustment hook 26 can be performed by rotating the adjustment bolt 47.
The position adjustment hook 25B and the angle adjustment hook 26 are arranged above the angle adjustment hook 26 along the substantially horizontal direction (adjustment direction) in a state of being engaged with the rotation center shaft 16 and the angle adjustment shaft 19. This prevents the hook portions from interfering with each other, and allows the brake shoe member 10 to be easily rotated after the position of the adjustment direction of the cable brake device 8 is determined.
Further, since the hook piece 25a of the position adjustment hook 25B is configured to engage with the rotation center shaft 16, it is not necessary to change the configuration of the conventional cable brake device in which the rotation center shaft 16 is supported by the pair of cable brake bases 11 fixed to the mounting base 3. Further, since the rotation center shaft 16 is moved, it is only necessary to secure strength of the screw-engagement portion of the brake case 12 and the rotation center shaft 16, and it is not necessary to unnecessarily increase the strength of the entire brake case 12.
The position adjustment hooks 25A and 25B are disposed on both sides of the brake shoe member 10 (brake case 12), and the hook pieces 25A engage with the rotation center shaft 16 disposed on the same axis. Thus, the position in the adjustment direction can be stably adjusted by the position adjustment hooks 25A and 25B, and positioning can be performed without inclining the cable brake device with respect to the adjustment direction.
The angle adjustment hook 26 is disposed above the position adjustment hook 25B on one side of the brake shoe member 10 (brake case 12). This can reduce the number of components for rotating the brake shoe member 10.
[ modified examples ]
The embodiments of the elevator apparatus and the method of adjusting the position of the rope brake apparatus according to the present invention, including the operational effects thereof, have been described above. However, the elevator apparatus and the method of adjusting the position of the rope brake apparatus according to the present invention are not limited to the above-described embodiments, and various modifications may be made without departing from the scope of the invention described in the claims.
For example, in the above-described embodiment, the adjusting bolt 44 is applied as a position adjusting hook moving mechanism for moving the position adjusting hooks 25A and 25B in the adjusting direction. Further, an adjusting bolt 47 is applied as an angle adjusting hook moving mechanism for moving the angle adjusting hook 26 in the adjusting direction. However, the position adjustment hook moving mechanism and the angle adjustment hook moving mechanism according to the present invention are not limited to the adjustment bolt, and for example, an electric cylinder, an actuator such as an electric slider, a belt mechanism, and the like can be applied.
In the above embodiment, the angle of the brake shoe member 10 is adjusted after the position of the cable brake device in the adjustment direction is adjusted. However, as a method of adjusting the position of the cable brake device according to the present invention, the position of the cable brake device in the adjustment direction may be adjusted after the angle of the brake shoe member 10 is adjusted. Further, only either adjustment may be performed.
