Problems to be solved by the invention
The ropes of an elevator are formed of a plurality of single-stranded wires, and thus the respective ropes are twisted, and the plurality of ropes are not arranged side by side but are scattered.
In a conventional rope gripping device for an elevator, a plate member sandwiching a plurality of ropes is separated into a support side and a pressure side. Therefore, the ropes are held in a manner that prevents the ropes from unraveling, while sandwiching the ropes with the separated 2-plate members. Then, the 2 plate members are pressed so that the plurality of ropes sandwiched therebetween are not loosened, and the 2 plate members are fastened and fixed by screws. Therefore, when the worker is a single person, there is a problem that a plurality of ropes cannot be well gripped in a state of being arranged side by side using the conventional rope gripping device for an elevator.
The present invention has been made to solve the above problems, and an object of the present invention is to provide a rope gripping device for an elevator, which can easily grip a plurality of ropes arranged side by one operator.
Means for solving the problems
The rope gripping device for an elevator of the present invention comprises: a base member having a plurality of rope holding grooves arranged in a direction perpendicular to a groove direction so that the groove direction is parallel to the groove direction on one surface of the base member; a 1 st shaft provided at one end side in the arrangement direction of the rope gripping grooves of the base member so that an axial direction thereof is parallel to a groove direction of the rope gripping grooves; and a 1 st pressing member having: a 1 st pressing body provided with a 1 st rope pressing groove corresponding to each of the rope holding grooves; a 1 st fitting part assembled to the 1 st pressing body; and a 1 st rotation direction changing lever. The 1 st pressing member is attached to the base member so as to be rotatable about the 1 st axis by fitting the 1 st fitting portion to the 1 st axis, and the 1 st pressing member is configured such that a rotatable direction of the 1 st pressing body about the 1 st axis is selectable between a closing direction and an opening direction by the 1 st rotation direction changing lever, the 1 st pressing member rotates in the closing direction to press the clamping rope by the rope gripping groove and the 1 st rope pressing groove to grip the rope, and the 1 st pressing member rotates in the opening direction to release the gripping of the rope.
Effects of the invention
According to the present invention, after the rope is set in the rope gripping groove of the open base member, the rotation direction of the pressing member is set to the closing direction by the rotation direction changing lever, and the rope can be gripped by the rope gripping device only by rotating the pressing member in the closing direction. Thus, the cord can be sandwiched between the base member and the pressing member while suppressing the cord from being loosened by simply rotating the pressing member about the 1 st axis. Further, a step of fixing the base member and the pressing member sandwiching the rope by other members is not required. Thus, even if the operator is a single person, the plurality of ropes can be easily gripped in a state of being arranged side by using the rope gripping device.

Detailed Description
First, before describing the embodiment, a rope winding method using the rope gripping device of the present invention will be described with reference to fig. 1. Fig. 1 is a schematic diagram for explaining a rope winding method using an elevator rope gripping device of the present invention.
In an elevator, as shown in fig. 1, a machine room 3 is provided in an upper part of a hoistway 1, and a hoisting machine 4 is provided in the machine room 3. In order to wind a rope in such an elevator, first, 3 drums 5 are carried into a pit 1a of a hoistway 1. Then, the end portions of the 3 ropes 6 fed out from the respective drums 5 are gripped by the rope gripping device 10. The rope gripping device 10 gripping the ends of the 3 ropes 6 is hoisted to the machine room 3 by the hoisting device 7 provided in the machine room 3. Next, the rope holding device 10 from which the hoisting device 7 is released from being fixed is held, and 3 ropes 6 are wound around the sheave 4a of the hoisting machine 4.
Next, the rope gripping device 10 is lowered in the hoistway 1, and the end of the rope 6 is connected to a counterweight (not shown) via a rope shackle in the pit 1 a. This allows the ropes 6 to be connected to the counterweight in a correct arrangement without crossing each other. The feeding side of the rope 6 is cut, and the cut side end portion is connected to a car (not shown) via a rope shackle. In addition, since the car is connected to the rope 6 in a state of being fixed to the upper portion of the hoistway 1, the length from the sheave 4a to the end of the rope 6 is short. Therefore, the ropes 6 are not crossed, and can be connected to the car in a correct arrangement.
Fig. 2 is a perspective view showing a rope gripping device according to embodiment 1 of the present invention, fig. 3 is a perspective view showing a base member of the rope gripping device according to embodiment 1 of the present invention, fig. 4 is a perspective view showing a pressing member of the rope gripping device according to embodiment 1 of the present invention, fig. 5 is a perspective view showing a pressing body of the pressing member constituting the rope gripping device according to embodiment 1 of the present invention, and fig. 6 is a perspective view showing a ratchet mechanism-equipped wrench constituting the pressing member of the rope gripping device according to embodiment 1 of the present invention.
In fig. 2, the rope gripping device 10 includes: a base member 11 that grips the rope 6; a pressing member 20 that presses the rope 6 against the base member 11 and fixes the rope 6 in cooperation with the base member 11; and a handle 28 attached to the base member 11.
As shown in fig. 3, the base member 11 includes: a rectangular flat plate-like base main body 12; rope holding grooves 13, which are fitted to the ropes 6, and 3 rows of which are arranged on one surface of the base body 12 so that the groove directions are parallel to each other; a guide part 14 formed at a central part in the groove direction of the rope gripping groove 13 on one surface of the base body 12 so as to protrude from the one surface of the base body 12 with the rope gripping groove 13 therebetween, and having a rope guide groove 15 extending from a protruding end to the rope gripping groove 13; and a pair of hexagonal prisms 16 that are provided upright on one end side in the arrangement direction of the rope gripping grooves 13 on one surface of the guide portion 14 in the groove direction of the rope gripping grooves 13 and on the other end side in the arrangement direction of the rope gripping grooves 13 on the other surface of the guide portion 14 in the groove direction of the rope gripping grooves 13 so that the axial direction is parallel to the groove direction of the rope gripping grooves 13.
As shown in fig. 4, the pressing member 20 includes a pressing body 21, a wrench 24 with a ratchet mechanism, and a rotation direction changing lever 27.
As shown in fig. 5, the pressing body 21 is formed in a rectangular flat plate shape having a length equal to the length of the base body 12 in the arrangement direction of the rope gripping grooves 13. A through hole 22 is formed on one end side in the longitudinal direction of the pressing body 21 so as to penetrate along the thickness direction. Further, 3 rope pressing grooves 23 are arranged on one side surface of the pressing body 21 at the same pitch as the rope holding grooves 13, and the groove direction of these rope pressing grooves 23 is the thickness direction of the pressing body 21.
As shown in fig. 6, the ratchet wrench 24 includes: a handle main body 25; and a socket 26 as a fitting portion to be assembled to one end of the handle main body 25. The socket 26 is configured to be able to fit into the hexagonal prism 16, and is rotatable in only one direction with respect to the handle main body 25 by a ratchet mechanism (not shown). The rotation direction changing lever 27 is provided to the handle body 25, and can select the rotation direction of the socket 26 with respect to the handle body 25. Further, since the ratchet mechanism is known in the art, the description thereof is omitted here.
The socket 26 is inserted into the through hole 22, and the handle body 25 is welded to the pressing body 21, whereby the ratchet wrench 24 is fixedly attached to the pressing body 21.
The handle 28 is attached to the base body 12.
Here, the rope gripping device 10 shown in fig. 2 is assembled by inserting the hexagonal prism 16 into the insertion opening 26 and attaching the pair of pressing members 20 to the base member 11 so as to sandwich the guide portion 14. In the rope gripping device 10 assembled in this way, the rotation direction changing lever 27 is operated to change the rotation direction of the socket 26, whereby the pressing member 20 can swing about the hexagonal prism 16.
Next, a method of gripping the rope 6 by the rope gripping device 10 configured as described above will be described with reference to fig. 7 and 8. Fig. 7 is a perspective view showing a state before the rope is gripped by the elevator rope gripping device of the present invention, and fig. 8 is a perspective view showing a state after the rope is gripped by the elevator rope gripping device of the present invention.
First, the rotation direction changing lever 27 is operated so that the pressing member 20 can rotate in the opening direction, which is the direction away from the one surface of the base body 12, with the hexagonal prism 16 as the rotation center. Then, the pair of pressing members 20 are rotated in the opening direction about the hexagonal prism 16 as a rotation center, thereby opening one surface side of the base main body 12. At this time, the rotation of the pressing member 20 toward the one surface side of the base body 12, that is, the rotation in the closing direction is prevented, and thus the state where the one surface side of the base body 12 is opened is maintained.
Next, for example, in the pit 1a of the hoistway 1, the end portions of the 3 ropes 6 fed out from the respective drums 5 are passed through the rope guide grooves 15, and inserted into the respective rope gripping grooves 13. Thereby, as shown in fig. 7, the end portions of the 3 ropes 6 are fitted into the rope holding grooves 13.
Next, the rotation direction changing lever 27 is operated so that the pressing member 20 can rotate in the direction of one surface of the base body 12, that is, in the closing direction with the hexagonal prism 16 as the rotation center. Then, the pair of pressing members 20 are rotated in the closing direction about the hexagonal prism 16 as a rotation center, thereby closing one surface side of the base body 12. By the rotation operation of the pressing member 20, the rope 6 is pressed to the rope gripping groove 13 by the rope pressing groove 23, and is pressed and held between the base member 11 and the pressing member 20. At this time, since the rotation of the pressing member 20 away from the one surface of the base body 12, that is, the rotation in the opening direction is prevented, the state in which the clamping cord 6 is pressed between the base member 11 and the pressing member 20 is maintained. Further, the movement of the pressing member 20 in the axial direction of the hexagonal prism 16 is restricted, and the attached state of the pressing member 20 is maintained. Thereby, as shown in fig. 8, 3 ropes 6 are gripped by the rope gripping device 10. The operator grips the handle 28 and winds the rope 6 around the sheave of the hoisting machine.
Next, the rotation direction changing lever 27 is operated so that the pressing member 20 can rotate in the opening direction with the hexagonal prism 16 as the rotation center. Then, the pair of pressing members 20 are rotated in the opening direction about the hexagonal prism 16 as a rotation center, thereby opening one surface side of the base main body 12. Thereby, the rope 6 is released from being gripped by the rope gripping device 10.
In fig. 2, the hexagonal prism 16, the pressing member 20, the pressing body 21, the socket 26, and the rotation direction changing lever 27 disposed above the guide portion 14 are the 1 st shaft, the 1 st pressing member, the 1 st pressing body, the 1 st fitting portion, and the 1 st rotation direction changing lever, respectively. On the other hand, the hexagonal prism 16, the pressing member 20, the pressing body 21, the socket 26, and the rotation direction changing lever 27 disposed below the guide portion 14 become a 2 nd shaft, a 2 nd pressing member, a 2 nd pressing body, a 2 nd fitting portion, and a 2 nd rotation direction changing lever, respectively.
According to embodiment 1, the base member 11 has a base body 12, and the rope holding grooves 13 are arranged in parallel on one surface of the base body 12. The hexagonal prism 16 is provided on one end side in the arrangement direction of the rope gripping grooves 13 of the base member 11 such that the axial direction is parallel to the groove direction of the rope gripping grooves 13. The pressing member 20 includes: a pressing body 21 provided with rope pressing grooves 23 corresponding to the rope holding grooves 13; and a ratchet mechanism-equipped wrench 24, and the pressing member 20 is integrally formed by welding the ratchet mechanism-equipped wrench 24 to the pressing body 21. The rotatable direction of the socket 26 with respect to the pressing body 21 can be selected by a rotation direction changing lever 27.
Therefore, after the rope 6 is set in the rope gripping groove 13 of the open base body 12, the rotation direction of the pressing member 20 is set to the closing direction by the rotation direction changing lever 27, and the rope 6 can be gripped by the rope gripping device 10 by simply rotating the pressing member 20 in the closing direction. Thus, the cord 6 can be sandwiched between the base member 11 and the pressing member 20 while suppressing the cord 6 from unraveling merely by rotating the pressing member 20 around the hexagonal prism 16. Further, a process of fixing the base member 11 and the pressing member 20, which sandwich the cord 6, by other members is not required. Thus, even if the operator is a single person, the plurality of ropes 6 can be gripped in a parallel arrangement by the rope gripping device 10.
The pair of hexagonal prisms 16 are provided on both ends of the base member 11 in the direction of arrangement of the rope gripping grooves 13 so that the axial direction thereof is parallel to the groove direction of the rope gripping grooves 13 and is spaced apart in the groove direction of the rope gripping grooves 13. The pair of pressing members 20 are disposed on both end sides in the arrangement direction of the rope gripping grooves 13 of the base member 11 by fitting the insertion holes 26 to the pair of hexagonal prisms 16, respectively. Therefore, the ropes 6 arranged side by side are pressed and held from both sides in the arrangement direction of the rope gripping grooves 13 by the pair of pressing members 20, and therefore, the ropes 6 are suppressed from being spread and the fluctuation of the rope holding force is suppressed. This enables the rope 6 to be gripped in a stable state by the rope gripping device 10.
Further, the guide portion 14 is provided to protrude from one surface of the base body 12 across each of the rope gripping grooves 13, and the rope guide groove 15 is formed from the protruding end of the guide portion 14 to the rope gripping groove 13. Therefore, by guiding the ropes 6 through the rope guide grooves 15 into the rope gripping grooves 13, the 3 ropes 6 can be provided to the base member 11 without being separated from each other, and therefore the gripping operation of the ropes 6 is facilitated.
In embodiment 1, the case where the number of ropes suspending the car is 3 has been described, but the number of ropes is not limited to 3. The number of rope holding grooves of the rope gripping device is set to correspond to the number of ropes suspending the car.
In embodiment 1, the ratchet mechanism-equipped wrench and the pressing body are welded to form an integral structure, but the socket may be assembled to the pressing body to form an integral structure.
